<First embodiment>
<1. Overview of beverage production equipment>
FIG. 1 is a schematic diagram of the beverage manufacturing apparatus 1, and FIG. 2 is a block diagram of a control device 11 of the beverage manufacturing apparatus 1. The beverage manufacturing apparatus 1 is an apparatus for automatically manufacturing a coffee beverage from roasted coffee beans and a liquid (here, water), and is capable of manufacturing one cup of coffee beverage per one manufacturing operation. The beverage manufacturing device 1 includes a bean processing device 2, an extraction device 3, and a control device 11.

  The control device 11 controls the entire beverage manufacturing device 1. The control device 11 includes a processing unit 11a, a storage unit 11b, and an I / F (interface) unit 11c. The processing unit 11a is a processor such as a CPU, for example. The storage unit 11b is, for example, a RAM or a ROM. The I / F unit 11c inputs and outputs signals between the external device and the processing unit 11a.

  The processing unit 11a executes a program stored in the storage unit 11b, and controls the actuator group 14 based on an instruction from the operation unit 12 or a detection result of the sensor group 13. The operation unit 12 is a unit that receives a user's instruction input, and is, for example, a touch panel or a mechanical switch. The user can instruct via the operation unit 12 to produce a coffee beverage. The sensor group 13 is various sensors (for example, a hot water temperature sensor, a mechanism operation position detection sensor, a pressure sensor, and the like) provided in the beverage manufacturing apparatus 1. The actuator group 14 is various actuators (for example, a motor, a solenoid valve, a heater, and the like) provided in the beverage manufacturing apparatus 1.

  The bean processing device 2 produces ground beans from roasted coffee beans. The extraction device 3 extracts coffee liquid from the ground beans supplied from the bean processing device 2. The extraction device 3 includes a fluid supply unit 7, a drive unit 8, which will be described later, an extraction container 9, and a switching unit 10. The ground beans supplied from the bean processing device 2 are put into the extraction container 9. The fluid supply unit 7 puts hot water into the extraction container 9. The coffee liquid is extracted from the ground beans in the extraction container 9. Hot water containing the extracted coffee liquid is delivered to the cup C as a coffee beverage via the switching unit 10.

<2. Fluid supply unit and switching unit>
The configurations of the fluid supply unit 7 and the switching unit 10 will be described with reference to FIG. First, the fluid supply unit 7 will be described. The fluid supply unit 7 supplies hot water to the extraction container 9 and controls the pressure in the extraction container 9. In the present specification, when the pressure is exemplified by a numeral, it means an absolute pressure unless otherwise specified, and the gauge pressure is a pressure at which the atmospheric pressure is set to 0 atm. The atmospheric pressure refers to the atmospheric pressure around the extraction container 9 or the air pressure of the beverage manufacturing device. For example, when the beverage manufacturing device is installed at a point at 0 m above sea level, the International Civil Aviation Organization (= “International Civil Aviation”) Aviation Organization [[abbreviation] ICAO]) is a standard atmospheric pressure (1013.25 hPa) at 0 m above sea level of the International Standard Atmosphere ([abbreviation] ISA)) established in 1976.

  The fluid supply unit 7 includes pipes L1 to L3. The pipe L1 is a pipe through which air flows, and the pipe L2 is a pipe through which water flows. The pipe L3 is a pipe through which both air and water can flow.

  The fluid supply unit 7 includes a compressor 70 as a pressure source. The compressor 70 compresses and sends out the atmosphere. The compressor 70 is driven using, for example, a motor (not shown) as a drive source. The compressed air sent from the compressor 70 is supplied to a reserve tank (accumulator) 71 via a check valve 71a. The air pressure in the reserve tank 71 is monitored by the pressure sensor 71b, and the compressor 70 is driven so as to be maintained at a predetermined air pressure (in this embodiment, 7 atm (6 atm in gauge pressure)). The reserve tank 71 is provided with a drain 71c for drainage, so that water generated by compression of air can be drained.

  Hot water (water) constituting the coffee beverage is accumulated in the water tank 72. The water tank 72 is provided with a heater 72a for heating the water in the water tank 72 and a temperature sensor 72b for measuring the temperature of the water. The heater 72a maintains the temperature of the accumulated hot water at a predetermined temperature (120 degrees Celsius in the present embodiment) based on the detection result of the temperature sensor 72b. For example, the heater 72a is turned on when the temperature of the hot water is 118 degrees Celsius, and is turned off when the temperature is 120 degrees Celsius.

  The water tank 72 is also provided with a water level sensor 72c. The water level sensor 72c detects the water level of the hot water in the water tank 72. When the water level sensor 72c detects that the water level has dropped below a predetermined water level, water is supplied to the water tank 72. In the case of this embodiment, tap water is supplied via a water purifier (not shown). An electromagnetic valve 72d is provided in the middle of the pipe L2 from the water purifier. When a decrease in the water level is detected by the water level sensor 72c, the electromagnetic valve 72d is opened to supply water, and when a predetermined water level is reached, the electromagnetic valve 72d is opened. The valve 72d is closed to shut off the water supply. In this way, the hot water in the water tank 72 is maintained at a constant water level. The water supply to the water tank 72 may be performed each time the hot water used for manufacturing the coffee beverage is discharged.

  The water tank 72 is also provided with a pressure sensor 72g. The pressure sensor 72g detects the atmospheric pressure in the water tank 72. The water tank 72 is supplied with the pressure in the reserve tank 71 via a pressure regulating valve 72e and a solenoid valve 72f. The pressure regulating valve 72e reduces the pressure supplied from the reserve tank 71 to a predetermined pressure. In the case of the present embodiment, the pressure is reduced to 3 atm (2 atm in gauge pressure). The solenoid valve 72f switches between supply and cutoff of the pressure regulated by the pressure regulating valve 72e to the water tank 72. The solenoid valve 72f is controlled to open and close so that the pressure in the water tank 72 is maintained at 3 atm except when tap water is supplied to the water tank 72. At the time of supply of tap water to the water tank 72, the air pressure in the water tank 72 is set to a pressure lower than the water pressure of the tap water by the solenoid valve 72h so that tap water is supplied to the water tank 72 smoothly by the water pressure. (For example, less than 2.5 atm). The solenoid valve 72h switches whether or not to release the inside of the water tank 72 to the atmosphere, and releases the inside of the water tank 72 to the atmosphere when the pressure is reduced. Also, the solenoid valve 72h releases the inside of the water tank 72 to the atmosphere when the pressure in the water tank 72 exceeds 3 atm and supplies the inside of the water tank 72 to 3 atm other than when supplying tap water to the water tank 72. maintain.

  Hot water in the water tank 72 is supplied to the extraction container 9 via the check valve 72j, the solenoid valve 72i, and the pipe L3. Hot water is supplied to the extraction container 9 by opening the electromagnetic valve 72i, and shut off by closing it. The amount of hot water supplied to the extraction container 9 can be controlled by the opening time of the solenoid valve 72i. However, the opening and closing of the solenoid valve 72i may be controlled by measuring the supply amount. The pipe L3 is provided with a temperature sensor 73e for measuring the temperature of the hot water, and monitors the temperature of the hot water supplied to the extraction container 9.

  The pressure in the reserve tank 71 is supplied to the extraction container 9 via a pressure regulating valve 73a and a solenoid valve 73b. The pressure regulating valve 73a reduces the pressure supplied from the reserve tank 71 to a predetermined pressure. In the case of the present embodiment, the pressure is reduced to 5 atm (4 atm in gauge pressure). The solenoid valve 73b switches between supply and cutoff of the pressure regulated by the pressure regulating valve 73a to the extraction container 9. The air pressure in the extraction container 9 is detected by the pressure sensor 73d. At the time of pressurizing the inside of the extraction container 9, the solenoid valve 73b is opened based on the detection result of the pressure sensor 73d, and the inside of the extraction container 9 is kept at a predetermined atmospheric pressure (in the case of the present embodiment, 5 atm (4 atm in gauge pressure) )). The pressure in the extraction container 9 can be reduced by the solenoid valve 73c. The solenoid valve 73c switches whether or not to release the inside of the extraction container 9 to the atmosphere, and releases the inside of the extraction container 9 to the atmosphere when the pressure is abnormal (for example, when the inside of the extraction container 9 exceeds 5 atm).

  After one production of the coffee beverage, in the case of the present embodiment, the inside of the extraction container 9 is washed with tap water. The solenoid valve 73f is opened at the time of washing, and supplies tap water to the extraction container 9.

  Next, the switching unit 10 will be described. The switching unit 10 is a unit that switches the destination of the liquid delivered from the extraction container 9 to one of the pouring unit 10c and the waste tank T. The switching unit 10 includes a switching valve 10a and a motor 10b that drives the switching valve 10a. The switching valve 10a switches the flow path to the pouring unit 10c when sending out the coffee beverage in the extraction container 9. The coffee beverage is poured into the cup C from the pouring section 10c. When discharging the waste liquid (tap water) and the residue (ground beans) at the time of washing, the flow path is switched to the waste tank T. The switching valve 10a is a three-port ball valve in this embodiment. Since the residue passes through the switching valve 10a at the time of washing, the switching valve 10a is preferably a ball valve, and the motor 10b switches its flow path by rotating its rotation shaft.

<3. Bean processing equipment>
The bean processing device 2 will be described with reference to FIG. FIG. 3 is a perspective view of the bean processing device 2. The bean processing device 2 includes a storage device 4 and a crushing device 5.

<3-1. Storage device>
The storage device 4 includes a plurality of canisters 40 in which roasted coffee beans are stored. In the case of the present embodiment, three canisters 40 are provided. When distinguishing three canisters 40, they are called canisters 40A, 40B, and 40C. Each of the canisters 40 </ b> A to 40 </ b> C may store different types of roasted coffee beans, and the operation input to the operation unit 12 may be used to select the type of roasted coffee beans used for manufacturing a coffee beverage. The different types of roasted coffee beans are, for example, roasted coffee beans having different types of coffee beans. The roasted coffee beans of different types are coffee beans of the same variety, but may be roasted coffee beans having different roasting degrees. Further, the roasted coffee beans having different types may be roasted coffee beans having different varieties and roasting degrees. Further, at least one of the three canisters 40 may accommodate roasted coffee beans in which a plurality of types of roasted coffee beans are mixed. In this case, the roasted coffee beans of each variety may have the same degree of roasting.

  Although a plurality of canisters 40 are provided in the present embodiment, a configuration in which only one canister 40 is provided may be employed. When a plurality of canisters 40 are provided, the same type of roasted coffee beans may be stored in all or a plurality of canisters 40.

  Each canister 40 is provided with a conveyor 41 individually. The conveyor 41 is a delivery mechanism (transport mechanism) for automatically delivering a predetermined amount of roasted coffee beans stored in the canister 40 to the downstream side. The conveyor 41 of the present embodiment is a screw conveyor using a motor 41a as a driving source, and is a weighing unit that automatically weighs roasted coffee beans. The delivery amount of roasted coffee beans can be controlled by the rotation amount of the motor 41a (the rotation amount of the screw). Each conveyor 41 discharges roasted coffee beans to a collective conveyance path 42 on the downstream side. The collective conveying path 42 is formed of a hollow member, includes an inlet 42a for each conveyor 41, and a common outlet 42b, and roasted coffee beans are supplied to the crusher 5 from the common outlet 42b. You.

<3-2. Crusher>
The pulverizing device 5 will be described with reference to FIGS. FIG. 4 is a longitudinal sectional view of the crusher 5. The pulverizing device 5 includes grinders 5A and 5B and a separating device 6. The grinders 5A and 5B are mechanisms for grinding the roasted coffee beans supplied from the storage device 4. The grinders 5A and 5B differ in the grain size at which the beans are ground. The grinder 5A is a grinder for coarse grinding, and the grinder 5B is a grinder for fine grinding.

<3-2-1. Grinder>
The grinder 5A includes a motor 52a and a main body 53a. The motor 52a is a drive source of the grinder 5A. The main body 53a is a unit that houses the cutter, and has a built-in rotation shaft 54a. The rotating shaft 54a is provided with a gear 55a, and the driving force of the motor 52a is transmitted to the rotating shaft 54a via the gear 55a.

  The rotary shaft 54a is provided with a rotary blade 58a as a cutter. Around the rotary blade 58a, a fixed blade 57a as a cutter is provided. The inside of the main body 53a communicates with the inlet 50a and the outlet 51a. The roasted coffee beans supplied from the collective conveyance path 42 enter the main unit 53a laterally from the input port 50a formed on the side of the main unit 53a, and are sandwiched between the rotary blade 58a and the fixed blade 57a. And crushed. A suppression plate 56a is provided above the rotary blade 58a of the rotating shaft 54a, and the suppression plate 56a suppresses roasted coffee beans from escaping upward. In the grinder 5A, the roasted coffee beans are ground to, for example, about 1/4. The pulverized ground beans are discharged to the separation device 6 from the discharge port 51a.

  Note that the roasted coffee beans supplied to the input port 50a may be supplied not at a position above the rotary blade 58a but at a height such that it hits the side surface. In this case, since the roasted coffee beans are prevented from escaping upward by the rotary blade 58a, the suppression plate 56a may not be provided.

  The grinder 5A may change the size of the roasted coffee beans discharged after being pulverized by changing the rotation speed of the rotary blade 58a. Further, the distance between the rotary blade 58a and the fixed blade 57a may be changed by manually adjusting the distance.

  The separation device 6 is a mechanism for separating unnecessary materials from the ground beans. The separation device 6 is disposed between the grinder 5A and the grinder 5B. That is, in the case of the present embodiment, the roasted coffee beans supplied from the storage device 4 are first coarsely ground by the grinder 5A, and the unnecessary material is separated from the coarsely ground beans by the separation device 6. The coarsely ground beans from which unnecessary materials are separated are finely ground by the grinder 5B. Unnecessary substances separated by the separation device 6 are typically chaff and fine powder. These may reduce the taste of the coffee beverage. The separating device 6 is a mechanism for separating unnecessary objects by the suction force of air, and the details thereof will be described later.

  The grinder 5B includes a motor 52b and a main body 53b. The motor 52b is a driving source of the grinder 5B. The main body 53b is a unit that houses the cutter, and has a built-in rotation shaft 54b. The rotating shaft 54b is provided with a pulley 55b, and the driving force of the motor 52b is transmitted to the rotating shaft 54b via the belt 59b and the pulley 55b.

  A rotary blade 58b is provided on the rotary shaft 54b, and a fixed blade 57b is provided above the rotary blade 58b. The inside of the main body 53b communicates with the inlet 50b and the outlet 51b. The ground beans falling from the separation device 6 enter the main body 53b from the input port 50b, and are further pulverized so as to be sandwiched between the rotary blade 58b and the fixed blade 57b. The ground beans ground into powder are discharged from the discharge port 51b. The particle size of the ground beans in the grinder 5B can be adjusted by adjusting the gap between the rotary blade 58b and the fixed blade 57b.

  The grinding of the roasted coffee beans may be performed by one grinder (one-stage grinding). However, by performing the two-stage pulverization using the two grinders 5A and 5B as in the present embodiment, the particle size of the ground beans can be easily made uniform, and the degree of extraction of the coffee liquid can be made constant. When the beans are crushed, heat may be generated due to friction between the cutter and the beans. By using two-stage pulverization, heat generation due to friction at the time of pulverization can be suppressed, and deterioration of the ground beans (for example, a decrease in flavor) can also be prevented.

  In addition, by going through the steps of coarse grinding → separation of unnecessary materials → fine grinding, when separating unnecessary materials such as chaff, the mass difference between the unnecessary materials and the ground beans (necessary part) can be increased. This can increase the efficiency of separating unnecessary substances and can prevent the ground beans (required portion) from being separated as unnecessary substances. In addition, since the separation of unnecessary substances using air suction is interposed between the coarse grinding and the fine grinding, the heat generation of the ground beans can be suppressed by air cooling. This can also prevent the deterioration of the ground beans (for example, a decrease in flavor).

<3-2-2. Separation device>
Next, the separation device 6 will be described with reference to FIGS. FIG. 5 is a partially cutaway perspective view of the separation device 6. The separation device 6 includes a suction unit 6A and a forming unit 6B. The forming unit 6B is a hollow body forming a separation chamber SC through which ground beans freely falling from the grinder 5A pass. The suction unit 6A communicates with the separation chamber SC in a direction (left and right direction in the present embodiment) crossing the direction in which the ground beans pass (in the present embodiment, the vertical direction), and the air in the separation chamber SC. This is a unit for sucking. By sucking the air in the separation chamber SC, light objects such as chaff and fine powder are sucked. Thereby, unnecessary materials can be separated from the ground beans.

  The suction unit 6A is a centrifugal separation type mechanism. The suction unit 6A includes a blowing unit 60A and a collection container 60B. In the case of the present embodiment, the blower unit 60A is a fan motor, and exhausts the air in the collection container 60B upward.

  The collection container 60B includes an upper portion 61 and a lower portion 62 that are separably engaged. The lower part 62 has a bottomed cylindrical shape whose upper part is open, and forms a space for storing unnecessary objects. The upper part 61 constitutes a lid mounted on the opening of the lower part 62. The upper part 61 includes a cylindrical outer peripheral wall 61a and an exhaust pipe 61b formed coaxially with the outer peripheral wall 61a. The blower unit 60A is fixed to the upper part 61 above the exhaust pipe 61b so as to suck air in the exhaust pipe 61b. The upper portion 61 also includes a cylindrical connecting portion 61c extending in the radial direction. The connecting portion 61c is connected to the forming unit 6B, and connects the separation chamber SC and the collection container 60B. The connection part 61c is open on the side of the exhaust pipe 61b.

  By driving the blower unit 60A, an airflow indicated by arrows d1 to d3 in FIG. 5 is generated. By this air flow, air containing unnecessary substances is sucked from the separation chamber SC into the collection container 60B through the connection portion 61c. Since the connection portion 61c is open to the side of the exhaust pipe 61b, the air containing unnecessary matter turns around the exhaust pipe 61b. Unnecessary matter D in the air falls due to its weight and is collected in a part of the collection container 60B (accumulates on the bottom surface of the lower part 62). The air is exhausted upward through the inside of the exhaust pipe 61b.

  A plurality of fins 61d are integrally formed on the peripheral surface of the exhaust pipe 61b. The plurality of fins 61d are arranged in the circumferential direction of the exhaust pipe 61b. Each fin 61d is obliquely inclined with respect to the axial direction of the exhaust pipe 61b. By providing such fins 61, the turning of the air including the unnecessary matter D around the exhaust pipe 61b is promoted. Further, the separation of the unnecessary matter D is promoted by the fins 61. As a result, the length of the suction unit 6A in the vertical direction can be reduced, which contributes to downsizing of the device.

  Further, in the present embodiment, the forming unit 6B is arranged on the path of falling of the ground beans by the grinders 5A and 5B, while the centrifugal suction unit 6A is arranged on the side of the falling path. The mechanism of the centrifugal separation method tends to be long in the vertical direction, but by disposing the suction unit 6A from the falling path and arranging the suction unit 6A on the side, the suction unit 6A is arranged side by side with respect to the grinder 5A and the grinder 5B. Can be. This contributes to reducing the vertical length of the device. In particular, when two-stage pulverization is performed by the two grinders 5A and 5B as in the present embodiment, the length of the device in the vertical direction tends to be longer. It is effective for conversion.

  The forming unit 6B will be described with reference to FIGS. FIG. 6 is a longitudinal sectional view of the forming unit 6B. FIG. 7 is a perspective view and a partially enlarged view of the forming unit 6B. FIG. 8 is a plan view of the forming unit 6B, and is a comparative explanatory view of the sectional area.

  In the case of the present embodiment, the forming unit 6B is formed by combining two members that are vertically divided in half. The forming unit 6B includes a tube portion 63 and a separation chamber forming portion 64, and has a spoon shape in plan view. The pipe portion 63 is a cylindrical body that forms a communication passage 63a with the suction unit 6A, and extends in a lateral direction (a direction intersecting a later-described center line CL). The separation chamber forming part 64 is an annular hollow body connected to the tube part 63 and forming the separation chamber SC and having a vertically opened center at the center.

  In the present embodiment, when separating unnecessary materials from the ground beans, a method is adopted in which the horizontal wind pressure acts on the ground beans falling from the grinder 5A to suck the unnecessary materials. This is advantageous in that the length in the vertical direction can be made shorter than in the centrifugal separation method.

  The separation chamber forming portion 64 includes a tubular portion 65 extending in the vertical direction. The cylindrical portion 65 protrudes into the separation chamber SC from the vertical center to the lower portion. The cylindrical portion 65 has an opening 65a at one end on the upper side, and the opening 65a forms an inlet for ground beans that is connected to the separation chamber SC. The opening 65a is located outside the separation chamber SC, and is connected to the outlet 51a of the grinder 5A. As a result, the ground beans falling from the discharge port 51a are introduced into the separation chamber forming section 64 without leakage. The cylindrical portion 65 has an opening 65b at the other end on the lower side. The opening 65b is located in the separation chamber SC. Since the opening 65b faces the separation chamber SC, the ground beans falling from the discharge port 51a are introduced into the separation chamber SC without leakage.

  In the case of the present embodiment, the tubular portion 65 has a cylindrical shape, and the openings 65a and 65b have concentric circular shapes located on the center line CL. This makes it easier for the ground beans falling from the discharge port 51a to pass through the tubular portion 65. The cylindrical portion 65 has a tapered shape in which the sectional area of the internal space gradually decreases from the opening 65a side toward the opening 65b side. Since the inner wall of the cylindrical portion 65 has a mortar shape, the falling beans can easily collide with the inner wall. In some cases, the ground beans falling from the grinder 5 </ b> A fall down as a lump with the particles adhered to each other. If the ground beans are in a lump state, the efficiency of separating unnecessary substances may decrease. In the case of the present embodiment, the lump of ground beans collides with the inner wall of the tubular portion 65, thereby breaking up the lump and making it easier to separate unnecessary substances.

  Note that the inner wall of the tubular portion 65 is not limited to the mortar shape in breaking the lump of ground beans. If there is a portion in the middle of the tubular portion 65 where the cross-sectional area of the internal space is smaller than that of the opening 65a, and if there is an inner wall inclined (not horizontal) with respect to the center line CL, collision with the lump may be prevented. While promoting, the ground beans can be dropped smoothly. Further, the cylindrical portion 65 does not need to protrude into the separation chamber SC, and may have only a portion protruding upward from the outer surface of the separation chamber forming portion 64. However, by projecting the cylindrical portion 65 into the separation chamber SC, the wind speed around the cylindrical portion 65 can be improved. For this reason, in the region R1 relatively far from the pipe portion 63, the effect of separating unnecessary substances by wind pressure can be enhanced.

  The separation chamber forming section 64 has a discharge port 66 communicating with the separation chamber SC, from which the ground beans after separating the unnecessary matter are discharged. In the case of the present embodiment, the outlet 66 is located below the opening 65b, and the ground beans that have passed through the cylindrical portion 65 pass through the separation chamber SC and fall freely from the outlet 66. In the case of the present embodiment, the outlet 66 is a circular opening located on the center line CL, and is a concentric opening with the openings 65a and 65b. For this reason, the ground beans can easily pass through the separation chamber forming section 64 by free fall, and the accumulation of the ground beans in the separation chamber forming section 64 can be prevented.

  As shown in FIG. 8, in the case of the present embodiment, the sectional area SC2 of the outlet 66 is larger than the sectional area SC1 of the opening 65b. In the case of the present embodiment, the opening 65b and the outlet 66 overlap each other when viewed in the up-down direction. Therefore, when the opening 65b is projected in the up-down direction with respect to the outlet 66, the opening 65b fits inside the outlet 66. In other words, the opening 65b is accommodated in a region in which the outlet 66 extends in the vertical direction. A configuration in which the opening 65b and the discharge port 66 are not on the same center line but overlap each other, or a configuration in which at least one is not circular but overlaps is also applicable.

  The ratio of the sectional area SC1 to the sectional area SC2 is, for example, 95% or less, or 85% or less, and is, for example, 60% or more, or 70% or more. Since the opening 65b and the outlet 66 are concentric, they overlap each other when viewed in the direction of the center line CL. For this reason, the ground beans that fall freely from the opening 65b are easily discharged from the discharge port 66. Further, it is possible to prevent the falling ground beans from colliding with the edge of the discharge port 66 and jumping to the pipe portion 63 side, and it is possible to prevent the required ground beans from being sucked into the suction unit 6A. Although the opening area of the one end opening (for example, 65a) is smaller than the opening area of the discharge opening (for example, 66), the opening area of the discharge opening (for example, 66) and the opening area of one end opening (for example, 65a) are described. The area may be the same, or the opening area of one end opening (for example, 65a) may be larger than the opening area of the discharge port (for example, 66). Although the opening area of the other end (for example, 65b) is smaller than the opening area of the outlet (for example, 66), the opening area of the outlet (for example, 66) and the other end (for example, 65b) are smaller. May have the same opening area, or the opening area of the other end opening (eg, 65b) may be larger than the opening area of the discharge port (eg, 66). Although the suction unit (for example, 6A) illustrates that the air is sucked from the outlet 66 and the inlet (for example, 65a, 65a '), the amount of air sucked from the inlet (for example, 65a, 65a') is smaller than the amount of air sucked from the inlet (for example, 65a, 65a '). The amount of air sucked from the outlet 66 may be larger. This is realized by the fact that the other end opening (for example, 65b) protrudes into the separation chamber and that the cross-sectional area of the discharge port 66 is larger than the opening area of the one end opening (for example, 65a). It may be realized by the fact that the cross-sectional area of the discharge port 66 is larger than the opening area of the other end opening (for example, 65b), or from the one end opening (for example, 65a) to the separation chamber. May be realized by making the distance from the discharge port 66 to the separation chamber shorter than the distance from the discharge port 66 to the exhaust pipe 61b rather than the distance from one end opening (for example, 65a) to the exhaust pipe 61b. It may be realized by a short distance, or by a distance from the outlet 66 to the blower unit 60A being shorter than a distance from one end opening (for example, 65a) to the blower unit 60A. Any one of the inner wall portions of the forming unit 6B and the members (63 to 65) constituting the separation chamber SC, the cylindrical portion 65, and the other end opening (for example, 65b), but at least one of the grinders (5A and 5B) ) May be configured to directly or indirectly contact with other members via other members, to transmit vibration caused by rotation of the grinder, and to vibrate. For example, in the case of the beverage manufacturing apparatus 1 in the embodiment, since they are in direct or indirect contact, during operation of the grinder, the members (63 to 65) of the forming unit 6B and the separation chamber SC are formed. Any of the inner wall portions, the cylindrical portion 65, and the other end opening (for example, 65b) vibrate, and the disturbed air generated in the separation chamber SC due to the vibration causes the other end opening (for example, 65b) to move to the separation chamber SC. A brake is applied to a light unnecessary object that enters, thereby facilitating the suction of the unnecessary object by a suction unit (for example, 6A). In particular, the forming unit 6B is in direct contact with the grinder 5A of the grinder 5A and the grinder 5B as in the beverage manufacturing apparatus 1 in the embodiment, and thus the forming unit 6B is brought into direct contact with one grinder. May be given an appropriate vibration to facilitate the suction of light unnecessary objects.

  In the case of this embodiment, the air sucked by the suction unit 6A is mainly sucked from the outlet 66. Therefore, a gap is provided between the discharge port 66 and the input port 50b of the grinder 5B, and the suction of air is promoted. The arrow d4 schematically shows the direction of the airflow of the air sucked by the suction unit 6A. By sucking air from the discharge port 66, unnecessary substances are less likely to be discharged from the discharge port 66, and the performance of separating ground beans and unnecessary substances can be improved. The air sucked by the suction unit 6A is also sucked from the opening 65a.

  A turbulence promoting portion 67 is formed on a peripheral wall defining the discharge port 66. The turbulence promoting unit 67 causes turbulence in the air sucked from the outlet 66 into the separation chamber SC. By forming the turbulence promoting portion 67, turbulence is likely to occur particularly in a region R2 between the opening 65b and the discharge port 66. Further, in the case of the present embodiment, since the wind speed increases around the cylindrical portion 65, the generation of turbulence in the region R2 can be synergistically promoted.

  The ground beans input into the input port 65a are stirred under the influence of the turbulent flow when passing through the region R2. In the case of the present embodiment, in particular, since the sectional area SC2 of the outlet 66 is larger than the sectional area SC1 of the opening 65b as described above, the ground beans always pass through the region R2. Turbulence facilitates the separation of unwanted matter such as chaff and fines from the ground beans. Therefore, even if the separation chamber SC is a small space, the separation efficiency of unnecessary substances can be improved, and in particular, it contributes to reducing the vertical length of the separation chamber SC, and as in the present embodiment, This is advantageous for miniaturization of the apparatus when two-stage pulverization is performed by the two grinders 5A and 5B.

  In the case of the present embodiment, the turbulence promoting unit 67 includes a plurality of turbulence promoting elements 67a. The turbulence promoting element 67a is a projection that protrudes downward in the up-down direction. The projecting direction of the turbulence promoting element 67a may be any direction. However, in order to more easily generate the turbulent flow in the separation chamber SC, a direction within a range from the lower direction to the radially inner direction is preferable. is there. If the projecting direction is downward as in the present embodiment, it is more preferable that the ground beans that have fallen will not be caught.

  The cross-sectional shape of the turbulence promoting element 67a is such that a trapezoidal quadratic prism is arranged so that the upper bottom of the cross section is directed in the direction of the center line CL, and a chamfer 67b is formed inside the front end. The shape of the turbulence promoting element 67a is not limited to the shape of the present embodiment, but a shape that complicates the shape of the outlet 66 three-dimensionally is preferable.

  In the case of the present embodiment, the turbulence promoting element 67a is formed repeatedly in the circumferential direction d5 of the outlet 66. Thereby, air is blown into the region R from multiple directions, and the generation of turbulence is promoted. The pitch of the adjacent turbulence promoting elements 67a may be different, but is equal in this embodiment. Although 12 turbulence promoting elements 67a are formed, the number of turbulence promoting elements 67a is arbitrary.

<3-2-3. Other Configuration Examples>
Another configuration example of the separation chamber forming section 64 will be described with reference to FIG. The turbulence promoting element 67a may be a notch or a hole in addition to the protrusion. The example of EX1 in FIG. 9 illustrates an example in which the turbulence promoting element 67a is a through hole formed in the peripheral wall of the outlet 66. Such holes can also promote the generation of turbulence in the region R2.

  The example of EX2 in FIG. 9 shows an example in which the tubular portion 65 is not provided. Also in this case, a configuration in which the sectional area SC2 of the outlet 66 is larger than the sectional area SC1 'of the inlet 65a' is preferable.

  The opening 65b of the tubular portion 65 may be an opening on an inclined surface instead of an opening on a horizontal plane. In the example of EX3 in FIG. 9, the lower end of the tubular portion 65 on the tube 63 side protrudes downward from the lower end on the opposite side. By doing so, the ground beans can be easily guided to the region R1 side, so that the residence time of the ground beans in the separation chamber SC can be increased, and the separation effect can be enhanced.

<4. Drive unit and extraction container>
<4-1. Overview>
The drive unit 8 and the extraction container 9 of the extraction device 3 will be described with reference to FIG. FIG. 10 is a perspective view of the drive unit 8 and the extraction container 9.

  The drive unit 8 is supported by the frame F. The frame F includes upper and lower beams F1 and F2 and a column F3 that supports the beams F1 and F2. The drive unit 8 is roughly divided into three units: an upper unit 8A, a middle unit 8B, and a lower unit 8C. The upper unit 8A is supported by the beam F1. The middle unit 8B is supported by the beam F1 between the beam F1 and the beam F2. The lower unit 8C is supported by the beam F2.

  The extraction container 9 is a chamber including a container main body 90 and a lid unit 91. The extraction container 9 may be called a chamber. The middle unit 8B includes an arm member 820 that detachably holds the container body 90. The arm member 820 includes a holding member 820a and a pair of shaft members 820b that are separated to the left and right. The holding member 820a is an elastic member such as a resin formed in a C-shaped clip shape, and holds the container body 90 by its elastic force. The holding member 82a holds the left and right sides of the container body 90, and exposes the front side of the container body 90. This makes it easier to visually recognize the inside of the container main body 90 in a front view.

  The container main body 90 is attached to and detached from the holding member 820a by a manual operation, and the container main body 90 is mounted on the holding member 820a by pressing the container main body 90 rearward in the front-rear direction against the holding member 820a. Further, the container main body 90 can be separated from the holding member 820a by pulling out the container main body 90 from the holding member 820a to the front side in the front-rear direction.

  Each of the pair of shaft members 820b is a rod extending in the front-rear direction, and is a member that supports the holding member 820a. In this embodiment, the number of the shaft members 820b is two, but may be one or three or more. The holding member 820a is fixed to front ends of the pair of shaft members 820b. By a mechanism described later, the pair of shaft members 820b is moved forward and backward, whereby the holding member 820a is moved forward and backward, so that a movement operation of moving the container body 90 in the front-rear direction can be performed. The middle unit 8B can also perform a turning operation to turn the extraction container 9 upside down, as described later.

<4-2. Extraction container>
The extraction container 9 will be described with reference to FIGS. FIG. 11 is a view showing a closed state and an open state of the extraction container 9, and FIG. 12 is an exploded perspective view of the extraction container 9. As described above, the extraction container 9 is turned upside down by the middle unit 8B. The extraction container 9 in FIGS. 10 and 11 shows a basic posture in which the lid unit 91 is located on the upper side. In the following description, a vertical positional relationship means a vertical positional relationship in a basic posture unless otherwise specified.

  The container main body 90 is a container with a bottom and has a bottle shape having a neck portion 90b, a shoulder portion 90d, a body portion 90e, and a bottom portion 90f. The whole or a part of the container main body 90 may have a transmission part. The transmission part may be made of a colorless transparent or colored transparent material. Thereby, the inside of the container main body 90 can be visually recognized from the outside. A flange portion 90c that defines an opening 90a that communicates with the internal space of the container body 90 is formed at an end of the neck portion 90b (an upper end portion of the container body 90).

  Each of the neck portion 90b and the body portion 90e has a cylindrical shape. In the neck portion 90b, a region having the same cross-sectional area or cross-sectional shape of the internal space extends in the vertical direction. The body 90e also has a region having the same cross-sectional area or cross-sectional shape extending vertically, and is longer than the neck 90b. The cross-sectional area of the internal space is larger in the trunk portion 90e than in the neck portion 90b. The ratio of the cross-sectional area of the neck portion 90b to the body portion 90e is, for example, 65% or less, 50% or less, or 35% or less, and is, for example, 10% or more, or 20% or more. The shoulder portion 90d is a portion between the neck portion 90b and the body portion 90e, and has a tapered shape such that the cross-sectional area of its internal space gradually decreases from the body portion 90e side to the neck portion 90b side. ing. However, the neck portion 90b is simply named for the position closer to the opening 90a than the bottom portion 90f, and the cross-sectional area of the internal space is not necessarily limited to the trunk portion 90e being larger than the neck portion 90b. Instead, the neck portion 90a may be a part of the body portion 90e. That is, the extraction container 9 may not have a shape having a constricted portion as shown in FIG. 10 and the like, and may have a small body shape or a small body shape and a flange portion such as 90c provided near the opening 90a or the opening 90a. The shape may be changed.

  The lid unit 91 is a unit that opens and closes the opening 90a. The opening / closing operation (elevation operation) of the lid unit 91 is performed by the upper unit 8A.

  The container main body 90 includes a main body member 900 and a bottom member 901. The main body member 900 is a cylindrical member that opens up and down and forms a neck portion 90b, a shoulder portion 90d, and a body portion 90e. The bottom member 901 is a member that forms the bottom part 90f, and is inserted and fixed below the main body member 900. A seal member 902 is interposed between the main body member 900 and the bottom member 901 to improve the airtightness inside the container main body 90.

  A convex portion 901c is provided at the center of the bottom member 901, and a shaft hole 901b is formed in the convex portion 901c. A plurality of communication holes 901a are formed around the shaft hole 901b. The communication hole 901a is a through hole that allows the inside of the container body 90 to communicate with the outside, and is mainly used for discharging waste liquid and residue when cleaning the inside of the container body 90.

  The shaft hole 901b penetrates the bottom member 901 and the shaft 903a of the plug member 903 is inserted therein. The plug member 903 opens and closes the communication hole 901a from inside the container body 90. A seal member 904 is provided between the plug member 903 and the inner side surface (upper surface) of the bottom member 901 to improve the airtightness in the container main body 90 when the plug member 903 is closed.

  On the outside (lower side) of the bottom member 901, a coil spring 905 and a cylindrical spring receiver 906 are mounted on the shaft 903 a, and an E-ring 907 is engaged with an end of the shaft 903 a. The coil spring 905 and the spring receiver 906 are held between the bottom member 901 and the E-ring 907, and the coil spring 905 urges the plug member 903 in the closing direction. The projection 901c is provided with a seal member 908. The seal member 908 is a member for maintaining the airtightness between the upper unit 8A or the lower unit 8C and the bottom member 901.

  The lid unit 91 includes a hat-shaped base member 911. The base member 911 has a protrusion 911d and a flange 911c that overlaps the flange 90c when closed. The base member 911 is provided with the same opening and closing mechanism as the plug member 903 in the container main body 90. Specifically, a shaft hole 911b is formed at the center of the base member 911, and a plurality of communication holes 911a are formed around the shaft hole 911b. The communication hole 911a is a through hole that allows the inside of the container body 90 to communicate with the outside, and is mainly used for injecting hot water into the container body 90 and sending out a coffee beverage.

  The shaft hole 911b penetrates the base member 911, and the shaft 913a of the plug member 913 is inserted therein. The plug member 913 opens and closes the communication hole 911a from inside the container main body 90. A seal member 914 is provided between the plug member 913 and the inner surface of the base member 911, and improves the airtightness in the container main body 90 when the plug member 913 is closed.

  Outside (upper side) of the base member 911, a coil spring 915 and a cylindrical spring receiver 916 are mounted on the shaft 913a, and an E-ring 917 is engaged with an end of the shaft 913a. The coil spring 915 and the spring receiver 916 are held between the base member 911 and the E-ring 917, and the coil spring 915 urges the plug member 913 in the closing direction. The protrusion 911d is provided with a seal member 918a and a ring spring 918b. The seal member 918a is a member for maintaining the airtightness between the upper unit 8A or the lower unit 8C and the base member 911. The ring spring 918b is an engagement member for holding the lid unit 91 on the upper unit 8A when the lid unit 91 is opened.

  A fixing member 919 is fixed to the inside (lower side) of the base member 911. The fixing member 919 supports the filter 910 and the holding member 910a. The filter 910 is a filter for separating a coffee beverage and ground bean residues, and is, for example, a metal filter. By using the metal filter, a coffee beverage containing coffee oil can be provided to the user. The holding member 910a is a porous member that suppresses deformation of the filter 910. The seal member 919a is supported by the fixing member 919. In the case of the present embodiment, the fixing member 919 is an elastic member, and the fixing member 919 and the sealing member 919a improve the airtightness between the lid unit 91 and the container body 90 when the lid unit 91 is closed.

  Note that a configuration that does not use the seal member 919a can be adopted by bringing the flange 90c and the flange portion 911c into airtight contact with each other.

<4-3. Upper unit and lower unit>
The upper unit 8A and the lower unit 8C will be described with reference to FIGS. FIG. 13 is a front view showing a configuration of a part of the upper unit 8A and the lower unit 8B, and FIG. 14 is a cross-sectional view taken along line II of FIG.

  The upper unit 8A includes an operation unit 81A. The operation unit 81A performs an opening / closing operation (elevating / lowering) of the lid unit 91 with respect to the container body 90 and an opening / closing operation of the plug members 903 and 913. The operation unit 81A includes a support member 800, a holding member 801, a lifting shaft 802, and a probe 803.

  The support member 800 is fixedly provided so that the relative position to the frame F does not change. Includes a housing section 800b that houses the holding member 801. The accommodation section 800b is a cylindrical space that opens downward and has a closed top. The support member 800 also includes a communication part 800a that allows the pipe L3 to communicate with the inside of the housing part 800b. Hot water, tap water, and air pressure supplied from the pipe L3 are introduced into the storage section 800b via the communication section 800a.

  The holding member 801 is a member that detachably holds the lid unit 91. The holding member 801 includes a housing portion 801b into which the protrusion 911d of the lid unit 91 or the protrusion 901c of the bottom member 901 is inserted. The accommodation section 801b is a cylindrical space that opens downward and has a closed top. The holding member 801 further includes a communication portion 801a that allows the housing portion 800b to communicate with the housing portion 801b. Hot water, tap water, and air pressure supplied from the pipe L3 are introduced into the storage unit 801b via the communication unit 800a and the communication unit 801a. The holding member 801 is a movable member provided to be slidable in the up-down direction in the housing portion 800b. The holding member 801 is formed with a seal member 801c for sealing between the holding member 801 and the housing portion 800b, so that the airtightness in the housing portion 800b is maintained even while the holding member 801 slides.

  An engagement portion 801d that protrudes radially inward is formed on the inner wall of the storage portion 801b. The lid unit 91 is held by the holding member 801 by the engagement between the engaging portion 801d and the ring spring 918b of the lid unit 91. When a force equal to or greater than a predetermined value acts to separate the holding member 801 and the lid unit 91 in the vertical direction, the engagement between the engaging portion 801d and the ring spring 918b is released by the elastic deformation of the ring spring 918b. Thereby, the lid unit 91 and the holding member 801 are separated.

  The elevating shaft 802 is provided so that its axial direction is the up-down direction. The elevating shaft 802 penetrates the top of the support member 800 in the up-down direction, and is provided to be vertically movable with respect to the support member 800. The support member 800 is provided with a seal member 800c at a portion of a hole through which the elevating shaft 802 passes, so that the airtightness in the housing portion 800b is maintained even while the elevating shaft 802 slides.

  The top of the holding member 801 is fixed to the lower end of the elevating shaft 802. The holding member 801 slides up and down by the raising and lowering of the elevating shaft 802, so that the holding member 801 can be attached to and separated from the protrusions 911 d and 901 c. Further, the lid unit 91 can be opened and closed with respect to the container body 90. FIG. 15 shows a case where the lid unit 91 is in the open state. The holding member 801 holding the lid unit 91 is at the raised position, and the held lid unit 91 is separated above the container body 90. FIG. 15 does not show some components.

  A screw 802a constituting a lead screw mechanism is formed on the outer peripheral surface of the elevating shaft 802. A nut 804b is screwed to the screw 802a. The upper unit 8A includes a motor 804a, and the nut 804b is rotated on the spot (without moving up and down) by the driving force of the motor 804a. The rotation of the nut 804b causes the lifting shaft 802 to move up and down.

  The elevating shaft 802 is a tubular shaft having a through hole at the center axis, and a probe 803 is inserted into the through hole so as to be slidable up and down. The probe 803 penetrates the top of the holding member 801 in the up-down direction, and is provided so as to be vertically movable with respect to the support member 800 and the holding member 801. The holding member 801 is provided with a seal member 801e at a portion of a hole through which the probe 803 passes, so that airtightness in the housing portion 801b is maintained even while the probe 803 slides.

  The probe 803 is provided coaxially with the axis 903a of the plug member 903 (and the axis 913a of the plug member 913). By lowering the probe 803, the shaft 903a of the plug member 903 is pressed downward, and the plug member 903 can be changed from the closed state to the open state. Note that the plug member 903 can be pressed from the closed state to the open state by using the pressure of the air supplied to the extraction container 9 or the pressure of water without using the probe 803. In this case, the air pressure or the water pressure may be set to a pressure higher than the urging force of the coil spring 905.

  FIG. 16 shows an opening and closing mode of the plug member 903 (and the plug member 913). The holding member 801 is at the lowered position, and the protrusion 911d is inserted into the holding member 801. Then, it is understood that the plug member 903 can be displaced to the open state shown by the broken line by the lowering of the probe 803 (not shown in FIG. 16). When the extraction container 9 is turned upside down, the plug member 913 can be changed from the closed state to the open state. FIG. 16 does not show some components.

  A screw 803a constituting a lead screw mechanism is formed on the outer peripheral surface of the probe 803. A nut 805b is screwed to the screw 803a. The upper unit 8A includes a motor 805a, and the nut 805b is provided so as to rotate on the spot (without moving up and down) by the driving force of the motor 805a. The probe 803 moves up and down by the rotation of the nut 805b.

  The lower unit 8C includes an operation unit 81C. The operation unit 81C has a configuration in which the operation unit 81A is turned upside down, and performs opening and closing operations of the plug members 903 and 913. The operation unit 81C is also configured to be able to open and close the lid unit 91. However, in this embodiment, the operation unit 81C is not used to open and close the lid unit 91.

  Hereinafter, the operation unit 81C is substantially the same as the operation unit 81A, but the operation unit 81C will be described. The operation unit 81C includes a support member 810, a holding member 811, an elevating shaft 812, and a probe 813.

  The support member 810 is fixedly provided so that the relative position to the frame F does not change. It includes a storage section 810b that stores the holding member 811. The accommodation section 810b is a cylindrical space that is open upward and has a closed bottom. The support member 810 further includes a communication part 810a that allows the switching valve 10a of the switching unit 10 to communicate with the inside of the storage part 810b. The coffee beverage, tap water, and ground bean residues in the container body 90 are introduced into the switching valve 10a via the communication portion 810a.

  The holding member 811 includes a housing portion 811b into which the protrusion 911d of the lid unit 91 or the protrusion 901c of the bottom member 901 is inserted. The accommodating portion 811b is a cylindrical space that opens upward and has a closed bottom. The holding member 811 further includes a communication portion 811a that connects the housing portion 810b and the housing portion 811b. Coffee beverage, tap water, and ground bean residues in the container main body 90 are introduced into the switching valve 10a through the communicating portions 810a and 811b. The holding member 811 is a movable member provided to be slidable in the up-down direction in the housing portion 810b. The holding member 811 is provided with a seal member 811c for sealing between the holding member 811 and the housing portion 810b, and the airtightness in the housing portion 810b is maintained even while the holding member 811 slides.

  An engagement portion 811d that protrudes radially inward is formed on the inner wall of the storage portion 811b. The lid unit 91 is held by the holding member 811 by the engagement between the engaging portion 811d and the ring spring 918b of the lid unit 91. When a force equal to or more than a predetermined value that vertically separates the holding member 811 and the lid unit 91 is applied, the engagement between the engaging portion 811d and the ring spring 918b is released by the elastic deformation of the ring spring 918b. Thereby, the lid unit 91 and the holding member 811 are separated.

  The elevating shaft 812 is provided so that its axial direction is the up-down direction. The elevating shaft 812 vertically penetrates the bottom of the support member 810 and is provided so as to be able to move up and down with respect to the support member 810. The support member 810 is provided with a seal member 810c at a portion of a hole through which the elevating shaft 812 passes.

  The bottom of the holding member 811 is fixed to the lower end of the elevating shaft 812. The holding member 811 slides up and down by the raising and lowering of the elevating shaft 812, so that the holding member 811 can be attached to and separated from the protrusions 901c and 911d. A screw 812a constituting a lead screw mechanism is formed on the outer peripheral surface of the elevating shaft 812. A nut 814b is screwed to the screw 812a. The lower unit 8C includes a motor 814a, and the nut 814b is rotated on the spot (without moving up and down) by the driving force of the motor 814a. The rotation of the nut 814b causes the lifting shaft 812 to move up and down.

  The elevating shaft 812 is a tubular shaft having a through hole at the center axis, and a probe 813 is inserted into the through hole so as to be slidable up and down. The probe 813 penetrates the bottom of the holding member 811 in the up-down direction, and is provided so as to be vertically movable with respect to the support member 810 and the holding member 811. The holding member 811 is provided with a seal member 811e at a portion of a hole through which the probe 813 passes, so that the airtightness in the housing portion 811b is maintained even while the probe 813 slides.

  The probe 813 is provided coaxially with the axis 913a of the plug member 913 (and the axis 903a of the plug member 903). By raising the probe 813, the shaft 913a of the plug member 913 is pressed upward, and the plug member 913 can be changed from the closed state to the open state. Note that, without using the probe 813, the plug member 913 can be pressed from the closed state to the open state using the air pressure of the air supplied to the extraction container 9 or the water pressure of the water. In this case, the air pressure or the water pressure may be higher than the urging force of the coil spring 915. For example, at least one or both of the charging of the liquid for steaming (for example, hot water) and the charging of the liquid for cleaning the extraction container 9 (for example, purified water, hot water, and a detergent) may be a liquid charging portion (plug member). Rather than opening the liquid 913 or the plug member 903) in advance and injecting the liquid, the user's preference, how to show the user through the transmission unit 101, and the degree of the force of the liquid are different from the usual. In order to do so, it may be preferable to close or open the input section (the plug member 913 or the plug member 903) less than the fully opened state and open the input section with the water pressure of the liquid to be input. For example, there is a case where the liquid instantaneously enters the extraction container 9 or is dropped on the shower on the inner wall portion of the extraction container 9 or the extraction target (eg, ground coffee beans).

  FIG. 16 shows an opening and closing mode of the plug member 913 (and the plug member 903). The holding member 811 is at the raised position, and the protrusion 901c is inserted into the holding member 811. Then, it is understood that the stopper member 913 can be displaced to the open state shown by the broken line by the raising of the probe 813 (not shown in FIG. 16). When the extraction container 9 is turned upside down, the plug member 903 can be changed from the closed state to the open state.

  On the outer peripheral surface of the probe 813, a screw 813a constituting a lead screw mechanism is formed. A nut 815b is screwed to the screw 813a. The lower unit 8C includes a motor 815a, and the nut 815b is provided so as to rotate on the spot (without moving up and down) by the driving force of the motor 815a. The probe 813 moves up and down by rotation of the nut 815b.

<4-4. Chubu Unit>
The middle unit 8B will be described with reference to FIGS. FIG. 17 is a schematic diagram of the middle unit 8B. The middle unit 8B includes a support unit 81B that supports the extraction container 9. The support unit 81B includes a unit main body 81B ′ that supports the lock mechanism 821, in addition to the arm member 820 described above.

  The lock mechanism 821 is a mechanism that maintains the lid unit 91 in a closed state with respect to the container main body 90. The lock mechanism 821 includes a pair of gripping members 821a that vertically clamp the flange 911c of the lid unit 91 and the flange 90c of the container body 90. The pair of gripping members 821a have a C-shaped cross section that fits by sandwiching the flange portion 911c and the flange portion 90c, and is opened and closed in the left and right directions by the driving force of the motor 822. When the pair of grip members 821a are in the closed state, as shown by the solid line in the encircled view of FIG. 17, each grip member 821a fits over the flange portion 911c and the flange portion 90c so as to sandwich the flange portion 911c up and down. The unit 91 is hermetically locked to the container body 90. In this locked state, the lid unit 91 does not move (the lock is not released) even if the lid unit 91 is opened by raising the holding member 801 by the elevating shaft 802. That is, the locking force of the lock mechanism 821 is set to be stronger than the force of opening the lid unit 91 using the holding member 801. Thus, it is possible to prevent the lid unit 91 from being opened with respect to the container main body 90 in the event of an abnormality.

  When the pair of grip members 821a are in the open state, as shown by the broken lines in the encircled view of FIG. 17, each grip member 821a is separated from the flange portion 911c and the flange portion 90c, and the lid unit 91 and the container main body 90 are separated. The lock with is released.

  Note that the C-shaped cross section of the gripping member 821a is rectangular (the upper side and the lower side are parallel) in the illustrated example, but may be a trapezoidal shape in which the cross-sectional area becomes narrower on the opening end side. Thereby, the flange portion 911c and the flange portion 90c can be more firmly locked.

  When the engaging portion 801d of the holding member 801 and the ring spring 918b of the lid unit 91 are in the engaged state, and when the holding member 801 is raised from the lowered position to the raised position, the pair of gripping members 821a are in the open state. The lid unit 91 is separated from the container body 90. Conversely, when the pair of gripping members 821a are in the closed state, the engagement between the engaging portion 801d and the ring spring 918b is released, and only the holding member 801 rises.

  The middle unit 8B also includes a mechanism that horizontally moves the arm member 820 in the front-rear direction using the motor 823 as a driving source. Thereby, the container main body 90 supported by the arm member 820 can be moved between the rear extraction position (state ST1) and the front bean insertion position (state ST2). FIG. 18 shows a movement mode of the container main body 90. In FIG. 18, the position of the container main body 90 indicated by a solid line indicates an extraction position, and the position of the container main body 90 indicated by a broken line is a bean input position. The bean charging position is a position where the ground beans are charged into the container body 90, and the ground beans ground by the grinder 5B are charged into the opening 90a of the container body 90 from which the lid unit 91 is separated. The extraction position is a position where the container main body 90 can be operated by the operation unit 81A and the operation unit 81C, is a position coaxial with the probes 803 and 813, and is a position where the coffee liquid is extracted. FIGS. 10, 13 to 16 show the case where the container main body 90 is at the extraction position. Thus, by making the position of the container main body 90 different between the input of the ground bean, the extraction of the coffee liquid, and the supply of the water, the steam generated at the time of extracting the coffee liquid is supplied to the grinder 5B, which is a supply section of the ground bean. Of the ground beans can be prevented from adhering to the outlet 51b due to the moisture of steam.

  Referring back to FIG. 17, the middle unit 8B also includes a mechanism for rotating the support unit 81B around a shaft 825 in the front-rear direction using the motor 824 as a drive source. Thereby, the posture of the container body 90 (extraction container 9) can be changed from the upright posture (state ST1) in which the neck portion 90b is on the upper side to the inverted posture (state ST3) in which the neck portion 90b is on the lower side. FIG. 13 shows a state where the extraction container 9 is in the upright posture. FIG. 19 illustrates a state in which the posture of the extraction container 9 is changed by rotating the extraction container 9. While the extraction container 9 is rotating, the state where the lid unit 91 is locked to the container main body 90 by the lock mechanism 821 is maintained. In FIG. 19, the extraction container 9 indicated by a solid line indicates an inverted posture state, and the extraction container 9 indicated by a broken line indicates an intermediate posture (a posture in the middle of rotation) between the upright posture and the inverted posture. The extraction container 9 is turned upside down between the upright posture and the inverted posture. The convex portion 911c is located at the position of the convex portion 901c in the upright posture, and the convex portion 911d is located at the position of the inverted posture. In the upright posture, the convex portion 911c is located at the position of the convex portion 911d in the upright posture. Therefore, in the inverted posture, the operation unit 81A can perform the opening / closing operation on the plug member 903, and the operation unit 81C can perform the opening / closing operation on the plug member 913.

  Note that the grip member 821a may include a grip cover. In this case, in order to reduce the rotation radius of the entire lock mechanism 821 during the rotation operation, the rotation surface may have a shape in which the outside of the gripper cover is cut in a front view. This makes it possible to protect the lock mechanism while preventing interference with other components.

  In the example of FIG. 17, the arm member 820 is moved forward and backward relative to the unit main body 81B ′. However, as shown in the example of FIG. 24, a mechanism for fixing the arm member 820 to the unit main body 81B ′ is also available. Can be adopted. In the example of FIG. 24, the unit main body 81B 'is horizontally moved in the front-rear direction by a mechanism using the motor 823 as a drive source. As a result, the arm member 820 also moves in the front-rear direction, so that the container body 90 can be moved between the extraction position and the bean charging position.

<5. Operation control example>
An example of control processing of the beverage manufacturing apparatus 1 executed by the processing unit 11a will be described with reference to FIGS. FIG. 20 shows a control example related to one coffee beverage production operation. The state of the beverage manufacturing apparatus 1 before the production instruction is called a standby state. The state of each mechanism in the standby state is as follows.

  The extraction device 3 is in the state of FIG. The extraction container 9 is in the upright posture and is located at the extraction position. The lock mechanism 821 is in a closed state, and the lid unit 91 closes the opening 90 a of the container main body 90. The holding member 801 is at the lowered position and is mounted on the convex portion 911d. The holding member 811 is at the raised position and is mounted on the convex portion 901c. The plug members 903 and 913 are in a closed state. The switching valve 10a makes the communication part 810a of the operation unit 81C communicate with the waste tank T. The standby state is not limited to the state of FIG. 10. For example, the extraction container 9 is in the upright posture and is located at the extraction position, the lock mechanism 821 is in the open state, and the lid unit 91 is in the open state of the container main body 90. 90a may be open.

  In the standby state, if there is a coffee beverage production instruction, the processing in FIG. 20 is executed. In S1, a pre-heat treatment is performed. This process is a process of pouring hot water into the container main body 90 and heating the container main body 90 in advance. First, the plug members 903 and 913 are opened. Thereby, the pipe L3, the extraction container 9, and the waste tank T are brought into a communicating state.

  The electromagnetic valve 72i is closed after being opened for a predetermined time (for example, 1500 ms). Thereby, hot water is poured from the water tank 72 into the extraction container 9. Subsequently, the solenoid valve 73b is opened for a predetermined time (for example, 500 ms) and then closed. Thereby, the air in the extraction container 9 is pressurized, and the discharge of hot water to the waste tank T is promoted. By the above processing, the inside of the extraction container 9 and the pipe L2 are preheated, and it is possible to reduce the cooling of hot water in the subsequent production of a coffee beverage.

  In addition, when hot water is injected into the extraction container 9 in the pre-heat treatment, the hot water passes through the filter 910. Even if the residue of the ground beans used in the previous production of the coffee beverage or the oil generated by extracting the coffee liquid has adhered to the filter 910, it is washed out and discharged.

  In S2, a grinding process is performed. Here, the roasted coffee beans are pulverized, and the ground beans are put into the container body 90. First, the lock mechanism 821 is opened, and the holding member 801 is raised to the raised position. The lid unit 91 is held by the holding member 801 and rises together with the holding member 801. As a result, the lid unit 91 is separated from the container body 90. The holding member 811 descends to the descending position. The container body 90 is moved to the bean charging position. Subsequently, the storage device 4 and the crushing device 5 are operated. Thereby, one cup of roasted coffee beans is supplied from the storage device 4 to the grinder 5A. The roasted coffee beans are ground in two stages by the grinders 5A and 5B, and unnecessary materials are separated by the separation device 6. The ground beans are put into the container body 90.

  Return the container body 90 to the extraction position. The holding member 801 is lowered to the lowered position, and the lid unit 91 is mounted on the container body 90. The lock mechanism 821 is closed, and the lid unit 91 is hermetically locked to the container body 90. The holding member 811 is raised to the raised position. Of the plug members 903 and 913, the plug member 903 is in an open state, and the plug member 913 is in a closed state.

  In S3, an extraction process is performed. Here, the coffee liquid is extracted from the ground beans in the container body 90. FIG. 21 is a flowchart of the extraction process in S3.

  In S11, in order to steam the ground beans in the extraction container 9, an amount of hot water smaller than one cup of hot water is poured into the extraction container 9. Here, the electromagnetic valve 72i is opened and closed for a predetermined time (for example, 500 ms). Thereby, hot water is poured from the water tank 72 into the extraction container 9. Then, after waiting for a predetermined time (for example, 5000 ms), the process of S11 ends. With this process, the ground beans can be steamed. Note that the pressure and temperature in the extraction container 9 after this treatment slightly increase, but there is no significant difference from before the treatment.

  By steaming the ground beans, carbon dioxide contained in the ground beans can be released, and the subsequent extraction effect can be enhanced. In order to steam the whole ground beans, the amount of hot water for steaming is preferably evenly applied to the ground beans. Therefore, when pouring hot water for steaming into the extraction container 9, the electromagnetic valve 72h may be temporarily opened and the water tank 72 may be poured while reducing the pressure. In this manner, the steaming hot water can be reduced, and the beans can be heated as evenly as possible, so that the steaming effect can be enhanced. The pressure in the extraction container 9 at the time of steaming may be lower than the pressure at the time of the subsequent immersion-type extraction (S14) described later (the pressure at which hot water does not boil). Thereby, the release of carbon dioxide gas can be promoted. When the ground bean is brought into contact with a liquid (for example, hot water), for example, during steaming, when immersing the carbon dioxide gas released from the ground bean, the release valve 73c is opened once after the steaming to open the air. It is also possible to release the ground beans without releasing them, and to immerse the ground beans later by applying the pressure of the carbon dioxide gas when immersing the ground beans in a liquid (for example, hot water). For example, in the case of the beverage manufacturing apparatus 1, the ground beans are steamed at 2 atm (3 atm in absolute pressure) or 0 atm (1 atm in absolute pressure), and then one cup is served at 2 atm (3 atm in absolute pressure). A liquid (for example, hot water) is poured into the extraction container 9, immersed at 4 atm (5 atm in absolute pressure), bumped at atmospheric pressure (0 atm (1 atm in absolute pressure)), and rotated in the extraction container 9. After that, immersion and sending out of the extraction container 9 are performed while giving a pressure of 0.7 atm (1.7 atm in absolute pressure) into the extraction container 9, but the pressure of the carbon dioxide gas released from the ground beans is also reduced. Taking into account, steaming, immersing or sending out the ground beans may be performed, and steaming may be performed after releasing carbon dioxide to the atmosphere before execution, or by releasing carbon dioxide to the atmosphere before immersion at 4 atm. Carbon dioxide gas is released to the atmosphere before the immersion at 2 atm before the 4 atm. The carbon dioxide gas may be or discharged into the atmosphere before the immersion and transmission of pressure. The steaming is performed by adding the pressure of carbon dioxide gas, and the immersion at 4 atm is also performed by adding the pressure of carbon dioxide (for example, the immersion is performed at 4 atm + the pressure of carbon dioxide). The immersion at 2 atm is also performed by adding the pressure of carbon dioxide gas (for example, the immersion is performed at the pressure of 2 atm + carbon dioxide gas). (For example, immersion at a pressure of 0.7 atm + carbon dioxide gas).

  The presence or absence of steaming may be selectable by setting. When the steaming is not performed, the water injection is performed only once, which has an effect of shortening the time until the completion of the production of the coffee beverage.

  In S12, the remaining amount of hot water is poured into the extraction container 9 so that one cup of hot water is stored in the extraction container 9. Here, the electromagnetic valve 72i is opened and closed for a predetermined time (for example, 7000 ms). Thereby, hot water is poured from the water tank 72 into the extraction container 9. In the present embodiment, the amount of hot water is managed by the opening time of the solenoid valve 72i, but the amount of hot water may be managed by measurement with a flow meter or measurement by another method.

  By the process of S12, the inside of the extraction container 9 can be brought into a state of a temperature of more than 100 degrees Celsius at 1 atm (for example, about 110 degrees Celsius). Subsequently, the inside of the extraction container 9 is pressurized by S13. Here, the electromagnetic valve 73b is opened and closed for a predetermined time (for example, 1000 ms), and the inside of the extraction container 9 is pressurized to a pressure at which hot water does not boil (for example, about 4 atm (about 3 atm in gauge pressure)). Thereafter, the plug member 903 is closed.

  Subsequently, this state is maintained for a predetermined time (for example, 7000 ms), and immersion coffee liquid extraction is performed (S14). Thus, the coffee liquor is extracted by the immersion method under high temperature and high pressure. The following effects can be expected by immersion extraction under high temperature and high pressure. First, by applying a high pressure, hot water can easily penetrate into the ground beans, and the extraction of coffee liquid can be promoted. Second, the high temperature promotes extraction of the coffee liquor. Third, by raising the temperature, the viscosity of the oil contained in the ground beans is reduced, and the extraction of the oil is promoted. Thereby, a fragrant coffee beverage can be manufactured. In addition, there is a view that if the coffee liquid is extracted at a high temperature, it is easy to produce an astringent taste. However, in the present embodiment, the separation device 6 removes unnecessary substances such as a chaff that causes the astringent taste. Therefore, even when the coffee liquid is extracted at a high temperature, the astringency can be suppressed.

  The temperature of the hot water (high-temperature water) may be higher than 100 degrees Celsius, but a higher temperature is more advantageous in extracting coffee liquid. On the other hand, raising the temperature of hot water generally increases costs. Therefore, the temperature of the hot water may be, for example, 105 degrees Celsius or higher, 110 degrees Celsius or higher, or 115 degrees Celsius or higher, and, for example, 130 degrees Celsius or lower, or 120 degrees Celsius or lower. The pressure may be any pressure at which hot water does not boil.

  In S15, the pressure inside the extraction container 9 is reduced. Here, the pressure in the extraction container 9 is switched to the pressure at which the hot water boils. Specifically, the plug member 913 is opened, and the electromagnetic valve 73c is opened and closed for a predetermined time (for example, 1000 ms). The inside of the extraction container 9 is released to the atmosphere. Thereafter, the plug member 913 is closed again.

  The pressure in the extraction container 9 is rapidly reduced to a pressure lower than the boiling point pressure, and the hot water in the extraction container 9 boils at a stretch. Hot water and ground beans in the extraction container 9 explode in the extraction container 9. Thereby, hot water can be boiled uniformly. Further, the destruction of the cell wall of the ground bean can be promoted, and the subsequent extraction of the coffee liquid can be further promoted. In addition, since the ground beans and the hot water can be stirred by the boiling, the extraction of the coffee liquid can be promoted. Thus, in this embodiment, the extraction efficiency of the coffee liquid can be improved. By opening the release valve (73c), the air pressure in the extraction container 9 is rapidly reduced. The rapid depressurization may be, for example, depressurizing at a speed at which one of a bumping state and a state close to bumping occurs. Specifically, the pressure in the extraction container 9 is reduced by a vapor pressure (saturated steam pressure, equilibrium pressure). The pressure may be reduced to a pressure less than the pressure below, or the liquid in the extraction container 9 (for example, hot water or a mixture of hot water and coffee liquid) may be suddenly boiled at a temperature exceeding the boiling point. The pressure may be reduced at an appropriate speed. Due to bumping (for example, a phenomenon in which a liquid that has not boiled (for example, hot water) suddenly boils at a temperature above the boiling point), the cells of the ground bean may be destroyed or the ground bean and the hot water may be stirred. .

  In S16, the extraction container 9 is reversed from the upright posture to the inverted posture. Here, the holding member 801 is moved to the raised position, and the holding member 811 is moved to the lowered position. Then, the support unit 81B is rotated. Thereafter, the holding member 801 is returned to the lowered position, and the holding member 811 is returned to the raised position. FIG. 23 shows the state of the inside of the extraction container 9 before and after inversion. The left side of the figure shows the extraction container 9 in the upright posture, and the right side of the figure shows the extraction container 9 in the inverted posture. The lid unit 91 including the neck portion 90b and the filter 910 is located on the lower side. The reversal from the upright posture to the inverted posture is not limited to rotating the extraction container 9 by 180 degrees by performing an operation involving rotation of the extraction container 9, and is not limited to rotating the extraction container 9 by 180 degrees (for example, 170 degrees). ) Or a certain angle exceeding 180 degrees (for example, 190 degrees). The extraction container 9 may be rotated to an angle exceeding ± 90 degrees. For example, with respect to the upright posture and the inverted posture, the upright posture is defined as a part that forms the opening 90a of the extraction container 9 and a part that does not form the opening 90a of the extraction container 9 and that is farthest from the certain part. It is a posture in which the certain part is located at a higher position than the distant part, and the inverted posture may be a posture in which the certain part is located in a lower position than the distant part. Is a posture in which the certain part is at a higher position than the distant part and is stationary, and the inverted posture is a state in which the certain part is at a lower position than the distant part and is stationary. The posture may be used. In addition, what kind of action is performed during the change in posture from the upright posture to the inverted posture, such as a predetermined number of rotations (for example, once or multiple times) of 360 degrees when the posture is changed from the upright posture to the inverted posture. The position of the extraction container 9 in the upright posture and the position of the extraction container 9 in the inverted posture may be different positions in front, rear, up, down, left and right, instead of merely rotating.

  In step S17, a permeation type coffee liquid extraction is performed, and the coffee beverage is delivered to the cup C. Here, the switching valve 10a is switched so that the pouring section 10c communicates with the passage section 810a of the operation unit 81C. In addition, both the plug members 903 and 913 are opened. Further, the solenoid valve 73b is opened for a predetermined time (for example, 10,000 ms), and the inside of the extraction container 9 is set to a predetermined pressure (for example, 1.7 atm (0.7 atm in gauge pressure)). In the extraction container 9, the coffee beverage in which the coffee liquid is dissolved in hot water passes through the filter 910 and is sent to the cup C. Filter 910 regulates the leakage of ground bean residues. By using both the immersion extraction in S14 and the permeation extraction in S17, the extraction efficiency of the coffee liquid can be improved. Thus, the extraction process ends. Here, an example is shown in which the pressure due to the carbon dioxide gas is not released to the atmosphere before the permeation-type coffee liquid extraction, but before the permeation-type coffee liquid extraction, the release valve 73c is opened to open the inside of the extraction container 9. It is preferable that the pressure due to the carbon dioxide gas is released to the atmosphere by releasing the carbon dioxide gas released from the ground beans of the ash to the atmosphere.

  In addition, at the time of the permeation type coffee liquid extraction in S17, only the plug member 903 may be in the open state, and may be once released to the atmospheric pressure. By doing so, it is possible to reduce the pressure inside the extraction container 9 which has been increased by the carbon dioxide gas generated during the immersion extraction. After performing this operation, the coffee member may be extracted by opening the plug member 913 and opening the electromagnetic valve 73b.

  The end of the extraction process may be determined based on a change in the pressure inside the extraction container 9 during the extraction process. For example, when the pressure drops below 1.7 atm to maintain 1.7 atm, pressurization is performed by opening and closing the solenoid valve 73b, and the time interval from pressurization to the next pressurization is less than half the time from the start of sending. , It may be determined that the transmission has been completed, and the extraction processing may be terminated. Alternatively, the determination may be made based on an increase in the number of pressurizations per unit time.

  Here, the relationship between the reversing operation in S16 and the transmission type coffee liquid extraction in S17 will be described with reference to FIG. When the extraction container 9 is in the upright posture, the ground beans are deposited from the body 90e to the bottom 90f. On the other hand, when the extraction container 9 is in the inverted posture, the ground beans are deposited from the shoulder 90d to the neck 90b. The cross-sectional area SC11 of the trunk portion 90e is larger than the cross-sectional area SC12 of the neck portion 90b, and the accumulation thickness H2 of the ground beans in the inverted posture is larger than the accumulation thickness H1 in the upright posture. That is, the ground beans are relatively thin and widely accumulated when the extraction container 9 is in the upright posture, and relatively thick and narrowly accumulated when the extraction container 9 is in the inverted posture.

  In the case of the present embodiment, since the immersion extraction in S14 is performed in a state where the extraction container 9 is in the upright posture, the hot water and the ground beans can be brought into wide contact with each other, and the extraction efficiency of the coffee liquid can be improved. However, in this case, the hot water and the ground beans tend to partially contact. On the other hand, since the permeation extraction in S17 is performed in a state where the extraction container 9 is in an inverted posture, the hot water passes through the accumulated ground beans while contacting more ground beans. The hot water comes into contact with the ground beans more evenly, and the extraction efficiency of the coffee liquid can be further improved.

  In reducing the cross-sectional area of the internal space of the extraction container 9 on the opening 90a side, the neck portion 90b may be formed so as to have a shape that is gradually narrowed (continuously inclined) to the opening 90a. It is preferable that a portion where the cross-sectional area of the neck portion 90b is constant is secured in the up-down direction by a certain length. By doing so, the amount of hot water permeated per unit volume of the ground bean can be made nearly uniform, so that over-extraction can be prevented and the efficiency of extraction by the permeation method can be increased. Further, the cross-sectional shape of the extraction container 9 is not limited to a cylindrical shape, and may be a rectangular tube shape or the like. However, the coffee liquid can be more uniformly extracted by using a cylindrical shape as in the present embodiment.

  Further, when the extraction container 9 is inverted, the hot water and the ground beans are stirred, so that the extraction efficiency of the coffee liquid can be further improved. In the case of the present embodiment, since the shoulder 90d is formed between the body 90e and the neck 90b, the ground beans can be smoothly moved from the body 90e to the neck 90b at the time of inversion.

  After the pressure reduction, the operation of shaking the extraction container 9 may be performed for the purpose of stirring the inside of the extraction container 9. Specifically, for example, the operation of tilting and returning the position of the extraction container 9 within a range of 30 degrees may be repeated a plurality of times. This shaking operation may be performed before or after the inversion of the extraction container 9.

  Further, in the present embodiment, the immersion extraction is performed in S14 before the decompression, but the immersion extraction may be performed after the decompression. In this case, the process in S14 may be deleted, The process of S14 may also be performed to perform the immersion extraction before and after the pressure reduction.

  Further, in the present embodiment, as a method of decompression in S15, the inside of the extraction container 9 is opened to the atmosphere, but the invention is not limited to this. Any method may be adopted, such as a method of conducting with the container of (1). However, the method of the present embodiment is advantageous in terms of the temperature in the subsequent extraction, the temperature of the coffee drink to be delivered, ease of decompression, and the width of decompression. Of course, the opening time of the release valve 73c may be adjusted so that the pressure after the pressure reduction becomes a certain pressure (for example, 1.1 atm) higher than the atmospheric pressure. The pressure after the pressure reduction may be set to a certain pressure lower than the atmospheric pressure (for example, 0.9 atm). Of course, the pressure after the pressure reduction may be set to the atmospheric pressure.

  In addition, in order to make the inside of the extraction container 9 a high-temperature and high-pressure state, in the present embodiment, a method of injecting high-temperature and high-pressure hot water into the extraction container is adopted. For example, a method of injecting water or hot water lower than a desired temperature into the extraction container 9 and then pressurizing and heating may be adopted.

  Returning to FIG. 20, after the extraction processing in S3, the discharging processing in S4 is performed. Here, processing related to cleaning of the inside of the extraction container 9 is performed. FIG. 22 is a flowchart thereof.

  In S21, the extraction container 9 is reversed from the inverted posture to the upright posture. Here, first, the plug members 903 and 913 are closed. The holding member 801 is moved to the raised position, and the holding member 811 is moved to the lowered position. Then, the support unit 81B is rotated. The lid unit 91 including the neck 90b and the filter 910 is located on the upper side. Thereafter, the holding member 801 is returned to the lowered position, and the holding member 811 is returned to the raised position. The inside of the extraction container 9 can be cleaned without removing the filter 910. In addition, the vibration of the extraction container 9 at the time of inversion or the impact at the time of completion of the inversion can promote the separation of the ground bean residue attached to the filter 910 from the filter 910 and dropping.

  In S22, the plug member 913 is opened. The solenoid valve 73f is opened and closed for a predetermined time (for example, 2500 ms). Thereby, tap water (purified water) is injected into the extraction container 9. The hot water in the water tank 72 can be used for cleaning, but the consumption of the hot water deteriorates the continuous production performance of the coffee beverage. For this reason, in this embodiment, tap water (purified water) is used. However, for cleaning, the hot water in the water tank 72 or the detergent delivered from a detergent tank (not shown) may be used.

  In the present embodiment, there is a portion near the end on the filter 910 side (neck portion 90b) where the cross-sectional outer shape is constant. For this reason, when pouring the water for cleaning into the extraction container 9, water can flow along the wall surface of the extraction container 9, and the cleaning effect can be improved.

  Before the injection of S22 or before the reversal of S21, the interior of the extraction container 9 may be released to the atmosphere for a predetermined time (for example, 500 ms). The residual pressure in the extraction container 9 can be released, and the water injection in S22 can be performed smoothly.

  When the inside of the extraction container 9 is thus released to the atmosphere, the inside of the extraction container 9 has a gauge pressure of 0 atm. Therefore, when water is injected, the plug member 913 may be automatically opened by water pressure. In this case, the process of opening the plug member 913 is unnecessary. When the plug member 913 is opened by the water pressure, the water is easily flowed along the inner wall surface of the extraction container 9 due to the balance between the force for returning the plug member 913 to the closed state and the water pressure, and the inside of the extraction container 9 Water is easily supplied to the whole.

  In S23, the plug member 903 is opened. The switching valve 10a makes the communication part 810a of the operation unit 81C communicate with the waste tank T. Thereby, the pipe L3, the extraction container 9, and the waste tank T are brought into a communicating state. The solenoid valve 73b is opened and closed for a predetermined time (for example, 1000 ms). Thereby, the pressure in the extraction container 9 is increased, and the water in the extraction container 9 is discharged to the waste tank T together with the residue of the ground beans. Thereafter, the plug members 903 and 913 are closed, and the process ends.

  Since the water used for cleaning is sent from the communication hole 901a different from the communication hole 911a for sending the coffee beverage, it is possible to prevent the communication hole 911a from being soiled.

  Note that the communication hole 901a may be larger than the communication hole 911a, thereby facilitating discharge of residues and the like. The pressurization in the extraction container 9 may be started in the middle of the water injection in S22. This makes it possible to more effectively discharge water and residues in S23. The pressurization in the extraction container 9 can be performed, for example, by rapidly increasing the pressure to about 5 atm (4 atm in gauge pressure), so that the residue can be discharged more vigorously. Water can be supplied to every corner in the interior 9 to improve the cleaning ability of the entire interior.

  Further, the plug members 903, 913 may not be closed after the process of S23 is completed, but may be kept open.

  Thus, one coffee beverage manufacturing process ends. Thereafter, the same processing is repeated for each manufacturing instruction. The time required for one production of a coffee beverage is, for example, about 60 to 90 seconds.

<Second embodiment>
Another processing example regarding the cleaning of the extraction container 9 will be described.

<Discharge processing>
In the discharge process illustrated in FIG. 22, the water injection and the discharge of the water and the residue in S22 and S23 are performed only once, but may be performed a plurality of times. Thereby, the inside of the extraction container 9 can be maintained more clean. FIG. 25 is a flowchart showing an example of a discharging process which is an alternative to the discharging process of FIG.

  The processing in S21 to S23 in FIG. 25 is the same as the processing in S21 to S23 in FIG. After the process in S23, it is determined in S24 whether the specified number of cleanings has been completed. The prescribed number of times is, for example, two times. If not completed, the process returns to S22, and the processes of S22 and S23 are executed again. If it has been completed, one discharge process ends.

  In addition, when repeating the processes of S22 and S23, the amount of water, the degree of pressurization, or the timing may be changed.

  Further, the plug member 903 may be in a closed state during the water injection in S22. In this case, water may be stored in the extraction container 9 to close the plug member 913, and the inverting operation of the extraction container 9 may be performed once or a plurality of times. Thereby, the cleaning effect in the extraction container 9 can be improved. When the water injection process of S22 is performed a plurality of times as in the example of FIG. 25, such an inversion operation of the extraction container 9 may be performed in the second and subsequent water injection processes. In the first time, the amount of the residue remaining in the extraction container 9 is large, and the scattering in the container is avoided.

<Re-cleaning process>
The extraction container 9 may be cleaned at a timing other than after the extraction of the coffee liquid. For example, it can be performed in a standby state. Alternatively, it can be performed when the user gives an instruction from the operation unit 12. The cleaning process of the extraction container 9 performed at a timing other than immediately after the extraction of the coffee liquid is referred to as a re-cleaning process. FIG. 26 is a flowchart illustrating an example of the re-cleaning process.

  In S31, a water injection process is performed. This is the same processing as S22. In S32, the water injected in S31 is drained. This is the same processing as S23. Thus, one unit process is completed.

  In addition, the plug member 903 may be closed at the time of water injection in S31. In the case of the discharging process in FIGS. 22 and 25, the plug member 903 may not be in the closed state during the water injection, but may be in the closed state only during the water re-cleaning process in FIG. Alternatively, the plug member 903 is closed during the water injection also in the case of the discharge processing in FIGS. 22 and 25, but the amount of water injection may be different between the case of the discharge processing and the case of the re-cleaning processing. Further, the water injection amount may be instructable by the user from the operation unit 12.

  In addition, the re-cleaning process is basically performed when the extraction container 9 is in the upright posture. However, the re-cleaning process may be performed with the extraction container 9 turned upside down and in an inverted posture.

  Further, after a certain period of time has elapsed since the production of the coffee beverage, the re-cleaning process using the hot water in the water tank 72 may be automatically performed. By performing this operation, the oil component and the like of the coffee liquid cooled and solidified in the flow path can be washed away.

<Third embodiment>
Another configuration example of the bean processing device 2 and the extraction device 3 will be described. In the following description, the same configurations as those in the first embodiment, or configurations having the same functions, are denoted by the same reference numerals as those in the first embodiment, description thereof will be omitted, and different configurations or functions will be mainly described. I do.

  As in the first embodiment, the extraction device 3 is disposed below the bean processing device 2 in this embodiment, and has a common basic structure. The bean processing device 2 includes a storage device 4 and a crushing device 5. The pulverizing device 5 includes a grinder 5A for coarse particles, a grinder 5B for fine particles, and a separating device 6 for separating unnecessary substances from the ground beans between them.

  The forming unit 6B of the separation device 6 and the grinder 5B are connected by a conveying pipe 500 extending obliquely downward from the rear to the front. The ground beans from which unnecessary materials have been removed by the separation device 6 are supplied to the grinder 5B through the transport pipe 500 (substantially fall naturally).

  The grinder 5B is provided with a nozzle type delivery pipe 501. The ground beans refined by the grinder 5B are discharged through the delivery pipe 501. The delivery pipe 501 is arranged such that its outlet is located just above the opening 90a of the container main body 90 when the container main body 90 is located at the bean input position. In the embodiment of FIG. 27, the container main body 90 is located at the extraction position, and the outlet of the delivery pipe 501 is located slightly in front of the container main body 90.

  In the case of the present embodiment, the container body 90 at the extraction position is located at a position laterally shifted from immediately below the grinder 5B. For this reason, the delivery pipe 501 is curved so that the ground beans are delivered to a position shifted from immediately below the grinder 5B.

  The main body 53 is provided with a gear 53b # for adjusting the grain size of the ground beans. The gear 53b 'is operated by a particle size adjusting mechanism (not shown).

<Suction unit>
The configuration of the suction unit 6A will be described with reference to FIGS. FIG. 28 is a vertical sectional view of the suction unit 6A. The suction unit 6A of the present embodiment is a centrifugal separation mechanism like the suction unit 6A of the first embodiment. The same applies to the basic operation. That is, the air in the collection container 60B is exhausted upward by the blowing unit 60A. Thereby, the air containing the unnecessary material from the forming unit 6B turns around the exhaust pipe 61b via the connection portion 61c, and the unnecessary material D falls into the collection container 60B due to its weight. When the air turns around the exhaust pipe 61b, the fin 61d accelerates the turning of the air and the separation of the unnecessary matter D.

  In the case of the present embodiment, the lower portion 62 of the collection container 60B includes an upper curved portion 62A and a lower collection portion 62B, which are separably engaged. The curved portion 62A is a cylindrical body that extends downward from the upper portion 61 and then bends forward.

  The collecting portion 62B is a straight bottomed cylindrical body without bending, and is fitted to the lower end of the curved portion 62A. For this reason, the collecting part 62B is attached obliquely downward from the rear to the front. Unnecessary materials D are collected in a part of the recovery unit 62B (accumulated on the bottom). When discarding the unnecessary material D, the collection unit 62B is removed from the bending unit 62A. At this time, the user only has to pull out the collection unit 62B downward and forward, so that the user can easily remove the collection unit 62B from the front of the apparatus.

  The upper portion 61 of the collection container 60B preferably extends in the vertical direction for centrifugation. By providing the curved portion 62A, it is possible to achieve both the centrifugal separation performance and the easy attachment and detachment of the recovery portion 62B.

  The lower part 62 of the collection container 60B may have a transmission part whose inside can be visually recognized from the outside. Alternatively, the curved portion 62A may be a non-permeable member, and only the collection portion 62B may be a transparent member. In any case, the user can visually check the amount of the unnecessary material D deposited.

<Chubu unit>
The configuration of the middle unit 8B, in particular, the configuration for moving the container body 90 in the horizontal direction and the like will be described with reference to FIGS. 27, 29 and 30. FIG. 29 is a partial perspective view of the horizontal movement mechanism provided in the middle unit 8B, and FIG. 30 is a partial perspective view of the arm member 820.

  As in the first embodiment, the arm member 820 includes a holding member 820a and a pair of shaft members 820b separated to the left and right. The pair of shaft members 820b are guided by the unit main body 81B 'so as to be able to move back and forth, and are supported. In this embodiment, the number of the shaft members 820b is two, but may be one or three or more.

  Racks 820c are provided at the rear ends of the pair of shaft members 820b, respectively. This rack 820c meshes with a pinion driven by a motor 823 (FIG. 17), and the arm member 820 moves in the front-rear direction by the rotation of the pinion. The movement range can be limited by the front and rear ends of the rack 820c interfering with other components (for example, a disk portion on the front side of the unit body 81B '). In the present embodiment, the arm member 820 is horizontally moved by the rack-pinion mechanism, but another driving mechanism such as a ball screw mechanism may be used.

  The holding member 820a is fixed to the front ends of the pair of shaft members 820b. The holding member 820a is an elastic member such as a resin as in the first embodiment, and holds the container body 90 by its elastic force. The container main body 90 is attached to and detached from the holding member 820a by a manual operation, and the container main body 90 is mounted on the holding member 820a by pressing the container main body 90 rearward in the front-rear direction against the holding member 820a. Further, the container main body 90 can be separated from the holding member 820a by pulling out the container main body 90 from the holding member 820a to the front side in the front-rear direction.

  The holding member 820a forms an annular frame that integrally includes a bottom portion BP, left and right side portions SP, an upper portion UP, and left and right locking portions EP. By forming the holding member 820a as an annular frame, high elasticity can be secured as a whole while allowing its elastic deformation.

  The bottom BP has a C-shape whose front side is open in plan view, and the container body 90 is mounted on the bottom BP. The left and right side parts SP extend upward from the left and right ends on the rear side of the bottom part BP, and are fixed to the front ends of the pair of shaft members 820b. In a state where the container main body 90 is held, the left and right side portions SP are located on the rear side of the side of the container main body 90. The upper part UP is formed so as to connect between the upper ends of the left and right side parts SP, and has an upwardly convex arch shape in the present embodiment. In a state where the container main body 90 is held, the upper UP is located on the rear side of the container main body 90, and the arch portion slightly overlaps the shoulder 90d. Thereby, the container main body 90 is prevented from being inadvertently displaced upward.

  The left and right locking portions EP extend upward and forward from the upper ends of the left and right side portions SP, and face slightly inward. In the state where the container main body 90 is held, the left and right locking portions EP are located from the side of the container main body 90 to the front side, and the front ends press the neck portion 90b from the front side. Thus, the container main body 90 is prevented from dropping from the holding member 820a to the front side.

  As described above, the holding member 820a of the present embodiment is configured so that the front side of the container main body 90 is easily visible from the front in a state where the container main body 90 is held, so that the user can easily confirm the operation of the container main body 90. . When the whole or a part of the container main body 90 has a transparent portion, the inside of the container main body 90 is easy to see from the front, and the extraction state of the coffee liquid is easy to see.

  A roller RL is provided on the rear side of the unit main body 81B '. The roller RL slides along a circular edge provided on the main body frame when the unit main body 81B 'rotates. The three rollers RL may be provided every 120 degrees or four every 90 degrees along the circumference of the unit main body 81B '. Regardless of the rotation angle of the unit body 81B ', at least one of the rollers RL is designed to support its weight by the circular edge of the body frame. By making the distance from the roller RL to the holding member 820a shorter than the distance from the portion supported behind the unit main body 81B ', vertical bending can be reduced.

<Storage device>
<Canister and its detachable structure (first example)>
The storage device 4 will be described with reference to FIG. 27 and FIGS. In the present embodiment, the canister 40 is configured as a cartridge that is detachable from the holder unit 43. Thereby, for example, the type of the roasted coffee beans can be easily and quickly exchanged. 31 is an exploded perspective view of the canister 40, FIG. 32 is a cross-sectional view of a cylindrical portion of the canister 40, FIG. 33 is an operation explanatory view of components of the canister 40, and FIG. 34 is a vertical cross-sectional view around the canister 40 in a mounted state. .

  The holder unit 43 includes a plurality of mounting portions 44. One canister 40 is detachably attached to one attachment portion 44. In the case of the present embodiment, the holder unit 43 includes three mounting portions 44. Therefore, three canisters 40 can be mounted at the same time. When distinguishing three canisters 40, they are called canisters 40A, 40B, and 40C.

  The canister 40 of the present embodiment is an elongated hollow bean container that stores roasted coffee beans. The canister 40 includes respective members of a tube portion 401, a lid portion 402, a connection portion 403, a packing 404, an outlet forming portion 405, and an outlet opening / closing portion 408.

  The cylindrical portion 401 has a cylindrical shape with both ends open, and defines a storage space for roasted coffee beans. Both ends of the cylindrical portion 401 constitute mouths through which roasted coffee beans can enter and exit. The mouth of the end of the cylinder 401 on the side of the lid 402 is a mouth through which the roasted coffee beans do not pass when the roasted coffee beans move from the canister 40 into the beverage manufacturing apparatus 1 (to the conveyor 41). The opening through which the roasted coffee beans pass when the lid 402 is opened to replenish the roasted coffee beans.

  In the case of the present embodiment, the cylindrical portion 401 is formed of a transmissive member. Thereby, the remaining amount of the roasted coffee beans contained can be visually recognized from the outside. On the peripheral wall of the cylindrical portion 401, a scale SC extends in parallel with the axial direction thereof. A scale is formed on the scale SC as a measure of the remaining amount of the roasted coffee beans. As shown in the cross-sectional view of FIG. 32, the scale SC also functions as a connection portion that connects the ends of the plate-like material forming the cylindrical portion 401.

  A cylindrical connecting portion 403 is fitted to one end of the cylindrical portion 401 via an annular packing 404. The packing 404 seals between the flange portion of the connection portion 403 and the edge of the cylindrical portion 401, but may be omitted. A female screw is formed on the inner peripheral surface of the connection portion 403. The cover portion 402 is formed with a male screw that is screwed to the female screw, and is detachable from the connection portion 403. Therefore, with the canister 40 attached to the attachment portion 44 as shown in FIG. 27, the lid portion 402 can be turned and removed to replenish roasted coffee beans.

  The lid 402 has a hemispherical shell shape, and closes one end of the cylinder 401. A plurality of recesses are formed in the outer peripheral surface of the cover 402 in the circumferential direction, so that the user can easily turn the cover 402 with his / her finger.

  The outlet forming portion 405 is fixed to the other end of the cylindrical portion 401 by bonding or the like. The outlet forming portion 405 is a cup-shaped member opened upward, and an outlet 405a is formed on a peripheral wall thereof. The outlet 405a is a port through which roasted coffee beans can enter and exit, and the roasted coffee beans stored in the cylindrical portion 401 can be discharged from the outlet 405a to the outside. That is, the outlet 405a is a port through which the roasted coffee beans pass when the roasted coffee beans move from the canister 40 into the beverage manufacturing apparatus 1 (to the conveyor 41), and a port for supplying the beans to the crushing apparatus 5. It is.

  The outlet forming portion 405 is also formed with a protrusion 405b, which protrudes outside the peripheral wall of the tube 401 through the opening 401a of the tube 401. A mark indicating the mounting direction of the canister 40 with respect to the mounting portion 44 is attached to the protrusion 405b.

  A detection piece 405c extending downward from the protrusion 405b is formed in the outlet forming section 405, and the detection piece 405c also protrudes outside the peripheral wall of the cylindrical section 401 through the opening 401a. The detection piece 405c is used to detect whether or not the canister 40 is mounted on the mounting section 44.

  A coil spring 407 is provided at the bottom of the outlet forming portion 405. A fixing member 406 is attached to the bottom of the outlet forming portion 405. FIG. 31 shows a state in which the fixing member 406 is assembled to the outlet forming portion 405. However, actually, after the outlet opening / closing portion 408 is attached to the outlet forming portion 405, the outlet forming portion 405 and the fixing member 406 Then, the fixing member 406 is attached to the outlet forming portion 405 so as to sandwich the outlet opening / closing portion 408.

  The outlet opening / closing unit 408 is a cup-shaped member that is open upward to receive the outlet forming unit 405, and forms a lid mechanism or a lid member that opens and closes the outlet 405a. An opening 408a is formed in the peripheral wall of the outlet opening / closing section 408. When the opening 408a overlaps with the outlet 405a, the outlet 405a is opened, and when the peripheral wall of the outlet opening / closing unit 408 overlaps with the outlet 405a, the outlet 405a is closed. That is, the outlet opening / closing section 408 is mounted on the outlet forming section 405 so as to be rotatable around the central axis of the cylindrical section 401 with respect to the outlet forming section 405. In the case of the present embodiment, the outlet opening / closing unit 408 is operated by a mechanism on the mounting unit 44 side described later, and opens / closes the outlet 405a.

  A cylindrical portion 408b projecting downward is provided at the bottom of the outlet opening / closing portion 408, and a space 408b 'inside the cylindrical portion 408b forms a concave portion in which the coil spring 407 is arranged. The fixing member 406 described above is inserted into the cylindrical portion 408b and is assembled to the outlet forming portion 405. The coil spring 407 constantly urges the outlet opening / closing section 408 in a direction away from the outlet forming section 405.

  A projection 408c is formed around the cylindrical portion 408b, and a notch 408d with which a claw 406a formed on the fixing member 406 engages is formed below the projection 408c.

  With reference to FIG. 33, the rotation restriction state and the rotation allowable state of the outlet opening / closing section 408 will be described. FIG. 33 shows a state where the outlet forming section 405, the outlet opening / closing section 408, and the fixing member 406 are assembled.

  State ST11 is a diagram in which the outlet forming section 405, the outlet opening / closing section 408, and the like are viewed from two directions in a state where the canister 40 is not mounted on the mounting section 44. The claw portion 406a is engaged with the notch 408d, and the rotation of the outlet opening / closing portion 408 with respect to the outlet forming portion 405 around the central axis of the cylindrical portion 401 is restricted. The outlet 405a is in a closed state. By the bias of the coil spring 407, the outlet forming portion 405 is biased in a direction away from the outlet opening / closing portion 408 as indicated by an arrow. Thereby, the engagement between the notch 408d and the claw portion 406a is strongly maintained. As described above, the notch 408d and the claw portion 406a function as a regulating mechanism that regulates the outlet opening / closing unit 408 from opening the outlet 405a when the canister 40 is not mounted on the mounting unit 44.

  State ST12 is a diagram in which the outlet forming section 405, the outlet opening / closing section 408, and the like are viewed from two directions in a state where the canister 40 is mounted on the mounting section 44. The mounting portion 44 is provided with a contact portion (a shutter portion 443 to be described later) that comes into contact with the outlet opening / closing portion 408. When the canister 40 is mounted on the mounting portion 44, the outlet opening / closing portion is opposed to the bias of the coil spring 407. The outlet opening / closing section 408 is relatively displaced toward the outlet opening / closing section 408 as indicated by the arrow.

  As a result, the notch 408d is separated from the claw portion 406a, and the engagement between them is released. The outlet opening / closing section 408 is allowed to rotate with respect to the outlet forming section 405 about the central axis of the cylindrical section 401. In the state ST12 of FIG. 33, the outlet 405a is in the closed state, but by rotating the outlet opening / closing unit 408, the outlet 405a can be opened.

  FIG. 34 is a vertical cross-sectional view of the state in which the canister 40 is mounted on the mounting portion 44, including the peripheral structure thereof. The mounting section 44 includes a cup-shaped main body section 441 into which an end of the canister 40 is inserted. The main body 441 has a front side opening upward. The end of the cylindrical portion 401 of the canister 40, the outlet forming section 405, and the outlet opening / closing section 408 are accommodated in the main body 441. The rear side has a lattice shape (rib shape). Is formed.

  A groove 441a with which the protrusion 405b is engaged is formed at an edge of the peripheral wall of the main body 441. A sensor 441b for detecting the detection piece 405c is disposed adjacent to the groove 441a. The sensor 441b is, for example, a photo interrupter. When the sensor 441b detects the detection piece 405c, the processing unit 11a recognizes that the canister 40 is mounted. Unless the sensor 441b detects the detection piece 405c, the processing unit 11a recognizes that the canister 40 is not mounted.

  A receiving portion 442 for receiving roasted coffee beans from the canister 40 is formed on the peripheral wall of the main body 441. In the case of the present embodiment, the receiving section 442 is an opening communicating with the inside of the conveyor 41. The roasted coffee beans discharged from the outlet 405a of the canister 40 are guided to the conveyor 41 through the receiving section 442.

  A shutter portion 443 which is a member having a cup shape that fits the outer shape of the outlet opening / closing portion 408 is provided in the main body portion 441. The shutter portion 443 is rotatably supported around the central axis of the canister 40 within the main body portion 441, and opens and closes the receiving portion 442. In the case of the present embodiment, a plurality of rollers 441d are arranged on the peripheral wall of the main body 441 in the circumferential direction (see FIG. 27). An opening that exposes the roller 441d to the inside is formed in the peripheral wall of the main body 441. The roller 441d is rotatably supported around an axis parallel to the radial direction of the canister 40. The outer peripheral surface of the shutter portion 443 is in contact with the plurality of rollers 441d inside the main body portion 441, and is rotatably supported.

  When the canister 40 is not mounted, the shutter unit 443 closes the receiving unit 442 to prevent foreign matter from entering the conveyor 41. FIG. 34 shows a state where the shutter unit 443 has closed the receiving unit 442. After the canister 40 is mounted, the shutter portion 443 can be rotated by driving the motor 41a, and the receiving portion 442 can be opened.

  The shutter 443 is attached to the rotating member 444. The rotating member 444 operates and rotates the outlet opening / closing unit 408 to open / close the outlet 405a. The rotation member 444 is connected to the drive shaft 445. The drive shaft 445 is disposed so as to be coaxial with the center axis of the canister 40 when the canister 40 is mounted, and is one of the elements for transmitting the driving force of the motor 41a to the rotating member 444. The rotating member 444 is a cylindrical member that opens upward on the front side. A groove 444a is formed at the edge of the peripheral wall of the rotating member 444, and the projection 408c of the outlet opening / closing portion 408 is engaged with the groove 444a. By this engagement, when the rotating member 444 is rotated, the outlet opening / closing section 408 is also rotated, and the outlet 405a is opened / closed. FIG. 34 shows a state in which the outlet opening / closing unit 408 closes the outlet 405a.

  According to the above configuration, the rotation of the rotating member 444 causes the shutter portion 443 to close the receiving portion 442 and the outlet opening / closing portion 408 to close the outlet 405a (the state in FIG. 34; this is referred to as a closed state). And a state in which the shutter unit 443 opens the receiving unit 442 and the outlet opening / closing unit 408 opens the outlet 405a (a state in which roasted coffee beans are supplied into the apparatus, which is referred to as an open state). The state of the storage device 4 can be switched. These states can be recognized by the processing unit 11a by detecting the rotational position of the shutter unit 443 by a sensor (not shown) (feedback control). As another example, a stepping motor may be used as the motor 41a, and the state of the storage device 4 may be recognized and switched based on the control amount (the number of steps) (open loop control).

  A bevel gear 445 a is provided on the drive shaft 445, and the bevel gear 445 a meshes with a bevel gear 445 b provided on the drive shaft 46.

  The drive shaft 46 is provided with a gear 45b that meshes with a pinion gear 45a provided on the output shaft of the motor 41a, and is rotated by the drive of the motor 41a. A one-way clutch 445c is interposed between the drive shaft 46 and the bevel gear 445b. One-way clutch 445c transmits only rotation of drive shaft 46 in one direction to bevel gear 445b. That is, when the motor 41a is rotated in one direction, the driving force of the motor 41a is transmitted to the rotating member 444 through the path of the bevel gear 445b, the bevel gear 445a, and the drive shaft 445. Is not transmitted when rotated in the other direction.

  The conveyor 41 is a transport mechanism that transports roasted coffee beans from the canister 40. In the case of the present embodiment, the conveyor 41 is provided not on the canister 40 side but on the mounting portion 44 side. That is, the conveyor 41 is provided so as to remain on the mounting unit 44 side when the canister 40 is removed from the mounting unit 44. Although a configuration in which the canister 40 and the conveyor 41 are integrated can be adopted, the canister 40 can be simplified and reduced in weight by being configured separately as in this embodiment.

  The screw shaft of the conveyor 41 is connected to the drive shaft 46 via a one-way clutch 47a. The drive transmission direction of the one-way clutch 47a is opposite to that of the one-way clutch 445c. In other words, when the motor 41a is rotated in the other direction, the driving force of the motor 41a is transmitted to the screw shaft 47, and the roasted coffee beans are conveyed, but when the motor 41a is rotated in one direction opposite to this. Is not transmitted.

  In this manner, in the present embodiment, the rotation of the rotating member 444 (that is, the rotation of the shutter unit 443 and the outlet opening / closing unit 408) and the rotation of the screw shaft 47 are exclusively performed by switching the rotation direction of the motor 41a between normal and reverse. be able to.

  A control example of the processing unit 11a relating to mounting and removing the canister 40 will be described. When the canister 40 is mounted on the mounting portion 44 by the user, this is detected by the sensor 441b. The processing unit 11a drives the motor 41a to open the shutter unit 443 and the outlet opening / closing unit 408. The protrusion 408c engages with a stopper 441c provided on the inner peripheral wall of the main body 441 in the axial direction of the canister 40, so that the canister 40 does not fall off the mounting portion 44 even when the user releases his hand. In other words, the protrusion 408c functions as a restricting portion that restricts the canister 40 from being removed from the mounting portion 44 when the outlet opening / closing portion 408 opens the outlet 405a. Thereby, it is possible to prevent the canister 40 from being removed and the roasted coffee beans in the canister 40 from falling off while the outlet 405a is kept open.

  The roasted coffee beans in the canister 40 are introduced into the conveyor 41 through the receiving unit 442 by opening the shutter unit 443 and the outlet opening / closing unit 408. Wait in this state.

  At the time of manufacturing a coffee beverage, the motor 41a is driven to rotate the screw shaft 47 and stop. Thus, the roasted coffee beans are transported to the collective transport path 42. The amount of roasted coffee beans used for producing a coffee beverage is automatically measured based on the rotation amount of the screw shaft 47. When one coffee beverage is to be produced and a plurality of roasted coffee beans are to be blended to produce a coffee beverage, the ratio of the transport amount to the collective transport path 42 by the conveyor 41 between the canisters 40 is changed. Is also good. As a result, ground beans in which a plurality of types of roasted coffee beans are blended can be supplied to the extraction container 9.

  When replacing the canister 40, the user issues a replacement instruction from the operation unit 12. The processing unit 11a drives the motor 41a to return the shutter unit 443 and the outlet opening / closing unit 408 to the closed state. The user can remove the canister 40 from the mounting section 44.

<Canister and its detachable structure (second example)>
A second example of the canister 40 and the mounting portion 44 partially different from the first example of the canister 40 and the mounting portion 44 described with reference to FIGS. 31 to 34 will be described with reference to FIGS. 35 to 47. Among the configurations of the second example, the same configurations as those of the first example or configurations having the same functions are denoted by the same reference numerals as those of the first example, and description thereof will be omitted. Will be described.

  35 to 37 show external views of the canister 40 and the mounting portion 44 of the second example viewed from multiple directions. In the main part 441 of the mounting part 44 of the first example, it has been described that the rear side is formed in a lattice shape (rib shape). However, the structure is the same as that of the main part 441 of the second example. 36 and so on. The rear side of the main body 441 is formed of a plurality of ribs 441e, and the rotating member 444 and the like inside the rib 441e are visible.

  The rotating member 444 has two detecting pieces 444b separated by 180 degrees in the circumferential direction. Two sensors 441f such as a photo interrupter are provided, and these detect two detection pieces 444b. The processing unit 11a recognizes the rotational position of the rotating member 444 based on the detection result of the sensor 441f. That is, it is recognized whether the shutter unit 443 and the outlet opening / closing unit 408 described in the first example are in the closed state or the open state.

  FIG. 38 is a vertical sectional view including the peripheral structure of the canister 40 mounted on the mounting portion 44. The structure of the second example is basically the same as that of the first example, except that an elastic deformation portion 405d is formed on the peripheral wall of the outlet forming portion 405 at the periphery of the outlet 405a. The elastically deforming portion 405d is a portion formed by inserting a slit parallel to the peripheral wall of the outlet forming portion 405 from the peripheral edge of the outlet 405a, and thereby is configured to be more easily deformed than the surrounding portion. The function of the elastic deformation portion 405d will be described later.

  The second example is different from the first example in the configuration relating to the rotation restriction and the rotation permission of the outlet opening / closing section 408. This point will be described with reference to FIGS. The state ST1 in FIG. 39 shows a case where the outlet opening / closing section 408 is in the rotation restricted state, and the state ST22 in FIG. 39 shows a case where the outlet opening / closing section 408 is in the rotation permissible state. FIG. 40 is a cross-sectional view taken along the line II-II of FIG. 39, and states ST21 and ST22 of FIG. 39 correspond to states ST21 and ST22 of FIG.

  In the second example, the coil spring 407 of the outlet forming portion 405 and the claw portion 406 a of the fixing member 406 in the first example are not provided, and the outlet opening / closing portion 408 is provided in the axial direction of the cylindrical portion 401 with respect to the outlet forming portion 405. However, only relative rotation is possible around this axis.

  The scale SC of the second example has a groove GR in which the slider 409 is incorporated. The slider 409 is configured by fastening a member on the front side and a member on the back side of the scale SC with two bolts, and is slidable along the groove GR in the longitudinal direction of the scale SC. As a configuration corresponding to the projection 405b and the detection piece 405c of the first example, the slider 409 has a projection 405b 'and a detection piece 405c'. The slider 409 also has a grip portion NB for the user to grip with a fingertip.

  The slider 409 has a protrusion 409a that can be engaged with one of the recesses CT1 and CT2 formed on the scale SC. The slider 409 is slidable between a first position where the protrusion 409a engages with the recess CT1 and a second position where the protrusion 409a engages with the recess CT2. State ST21 and state ST22 show a state where the slider 409 is located at the first position, and state ST23 of FIG. 40 shows a state where the slider 409 is located at the second position. The slider 409 is basically located at the first position, and is manually slid to the second position when the bite of roasted coffee beans described later is released.

  At the end of the scale SC of the second example, a cylindrical support portion SC 'opened toward the outlet forming portion 405 is fixed. The support portion SC 'supports a coil spring 407 of the first example, a coil spring 407' replacing the claw portion 406a, and a movable member 406a '. A notch 408d 'is formed at the edge of the outlet opening / closing portion 408 in place of the notch 408d of the first example. As shown in state ST21, the engagement of the movable member 406a 'with the notch 408d' regulates the rotation of the outlet opening / closing portion 408 relative to the outlet forming portion 405 about the central axis of the cylindrical portion 401. At this time, the outlet 405a is in a closed state. The movable member 406a 'is constantly urged toward the notch 408d' by the coil spring 407 '. Thereby, the engagement between the notch 408d 'and the movable member 406a' is strongly maintained. As described above, the notch 408d 'and the movable member 406a' function as a regulating mechanism that regulates the outlet opening / closing unit 408 from opening the outlet 405a when the canister 40 is not mounted on the mounting unit 44.

  When the canister 40 is mounted on the mounting portion 44, as shown in a state ST22, the movable member 406a 'abuts on the edge of the shutter portion 443 and is pushed into the support portion SC' against the bias of the coil spring 407 '. It is. As a result, the engagement between the movable member 406a 'and the notch 408d' is released, and the rotation of the outlet opening / closing portion 408 relative to the outlet forming portion 405 around the central axis of the cylindrical portion 401 is allowed.

  In the second example, a control example of the processing unit 11a relating to mounting and dismounting of the canister 40 will be described mainly with reference to FIGS. When the canister 40 is mounted on the mounting portion 44 by the user, the movable member 406a 'comes into contact with the edge of the shutter portion 443, whereby the engagement between the movable member 406a' and the notch 408d 'is released ( (State of state ST22).

  The mounting of the canister 40 is detected by the sensor 441b, and the processing unit 11a drives the motor 41a to open the shutter unit 443 and the outlet opening / closing unit 408. The state ST31 in FIG. 41 illustrates a case where the outlet opening / closing unit 408 is in the closed state, and the state ST32 illustrates a case where the outlet opening / closing unit 408 shifts from the state ST31 to the open state.

  When the shutter portion 443 and the outlet opening / closing portion 408 are opened, the projection 408c engages with the stopper 441c provided on the inner peripheral wall of the main body portion 441 in the axial direction of the canister 40. 40 does not fall off from the mounting portion 44. In other words, the protrusion 408c functions as a restricting portion that restricts the canister 40 from being removed from the mounting portion 44 when the outlet opening / closing portion 408 opens the outlet 405a. Thereby, it is possible to prevent the canister 40 from being removed and the roasted coffee beans in the canister 40 from falling off while the outlet 405a is kept open.

  The roasted coffee beans in the canister 40 are introduced into the conveyor 41 through the receiving unit 442 by opening the shutter unit 443 and the outlet opening / closing unit 408. Wait in this state.

  At the time of manufacturing a coffee beverage, the motor 41a is driven to rotate the screw shaft 47 and stop. Thus, the roasted coffee beans are transported to the collective transport path 42. The amount of roasted coffee beans used for producing a coffee beverage is automatically measured based on the rotation amount of the screw shaft 47.

  A beans remaining amount detection sensor SR is provided at the base of the receiving unit 442. The beans remaining amount detection sensor SR is, for example, a transmission type sensor (photo interrupter). If coffee beans are manufactured a predetermined number of times (for example, two cups) after it is detected that there is no bean at this position, it may be notified that the contents of the canister 40 are empty.

  When replacing the canister 40, for example, the user issues a replacement instruction from the operation unit 12. The processing unit 11a drives the motor 41a to return the shutter unit 443 and the outlet opening / closing unit 408 to the closed state. A state ST33 in FIG. 41 shows a state in which the outlet opening / closing unit 408 is returning to the closed state from the state ST32.

  When the shutter portion 443 and the outlet opening / closing portion 408 are closed, the engagement between the protrusion 408c and the stopper 441c is released, and the user can remove the canister 40 from the mounting portion 44. When the canister 40 is removed from the mounting portion 44, the movable member 406a 'is engaged with the notch 408d' again by the bias of the coil spring 407 '(state in the state ST21). Accordingly, the rotation of the outlet opening / closing portion 408 with respect to the outlet forming portion 405 about the central axis of the cylindrical portion 401 is again regulated, and the roasted coffee beans remaining in the canister 40 from the outlet 405a may be inadvertently spilled. Is prevented.

<Measures against biting>
When the shutter section 443 and the outlet opening / closing section 408 are returned from the open state to the closed state, the degree of exposure (opening area) of the outlet 405a gradually decreases as it overlaps with the peripheral wall of the outlet opening / closing section 408. A change in the degree of exposure of the outlet 405a in the process of returning the outlet opening / closing unit 408 from the open state to the closed state is shown below the broken line in FIG.

  The edge ED1 of the peripheral wall defining the outlet 405a of the outlet forming portion 405, and the edge ED2 of the peripheral wall defining the opening 408a of the outlet opening / closing portion 408 are both bulged in directions facing each other, The outlet 405a is shaped so that the width of the outlet 405a becomes wider on the cylindrical portion 401 side. This makes it easy for the roasted coffee beans located between the edge ED1 and the edge ED2 to be extruded toward the cylinder portion 401 side, so that the beans are less likely to bite at a plurality of points. The edges ED1 and ED2 may not be inflated, but may be in a straight line shape, and may have a shape in which the width of the outlet 405a on the cylindrical portion 401 side is widened.

  Since the end of the edge ED1 is formed by the elastic deformation portion 405d, when the roasted coffee beans are about to be caught between the elastic deformation portion 405d and the edge ED2 just before the outlet 405a is closed, the elastic deformation occurs. The portion 405d is deformed and the beans are easily flipped. This can further prevent biting of the roasted coffee beans.

  Next, a control example relating to prevention of biting of roasted coffee beans will be described. 42 to 44 are cross-sectional views in the radial direction of the canister 40, and illustrate the state of roasted coffee beans to be stored. 42 to 44 exemplify the control from mounting to removal of the canister 40.

  FIG. 42 shows a state immediately after the canister 40 is mounted on the mounting section 44. The shutter section 443 and the outlet opening / closing section 408 are in a closed state. FIG. 43 shows a state in which the shutter unit 443 and the outlet opening / closing unit 408 have been switched from the state of FIG. 42 to the open state. The outlet 405a and the receiving part 442 are opened, and the roasted coffee beans flow into the conveyor 41.

  FIG. 44 shows a state where the shutter section 443 and the outlet opening / closing section 408 return to the closed state again. Before the outlet 405a is completely closed, the rotation of the shutter unit 443 and the outlet opening / closing unit 408 is stopped once. The outlet 405a is partially closed, and is opened, for example, so that one roasted coffee bean can pass through. When the motor 41a is a stepping motor, the opening degree of the outlet 405a can be controlled by the control amount (the number of steps).

  In this state, the conveyor 41 is driven to remove the roasted coffee beans from around the receiving section 442. Thereafter, the conveyor 41 is stopped, the shutter unit 443 and the outlet opening / closing unit 408 are completely closed, and the closed state is completely returned. This makes it possible to more reliably prevent the roasted coffee beans from biting.

  As shown in FIGS. 42 to 44, the cross-sectional shape of the edge of the outlet forming portion 405, the outlet opening / closing portion 408, and the shutter portion 443 has a wedge shape or a tapered shape. Since the contact area between the roasted coffee beans and the edge is reduced, it contributes to prevention of biting.

  As shown in the cross-sectional views of FIGS. 34 and 38, the space around the receiving portion 442 has a larger volume on the front side than on the rear side. Thereby, when returning the shutter part 443 and the outlet opening / closing part 408 from the open state to the closed state, it is possible to secure a larger space around the outlet 405a, which gradually narrows, and to prevent the roasted coffee beans from biting. By narrowing the rear side, the roasted coffee beans remaining here can be reduced, and when driving the conveyor 41 in the state of FIG. 44, the roasted coffee beans carried out by the conveyor 41 (for example, discarded) ) Can be reduced.

  45 to 47 are radial cross-sectional views of the canister 40, and illustrate the state of roasted coffee beans to be stored. FIGS. 45 to 47 illustrate a case where the shutter 443 and the outlet opening / closing unit 408 are returned from the open state to the closed state in a state where a relatively large amount of roasted coffee beans remains in the receiving unit 442 and the canister 40. I have.

  FIG. 45 shows a case where the shutter unit 443 and the outlet opening / closing unit 408 are in an open state. A relatively large amount of roasted coffee beans stays near the outlet 405a and the receiving section 442.

  FIG. 46 shows a state in which the shutter section 443 and the outlet opening / closing section 408 return to the closed state. As in the example of FIG. 44, before the outlet 405a is completely closed, the rotation of the shutter unit 443 and the outlet opening / closing unit 408 is stopped once. In this state, the conveyor 41 is driven to remove the roasted coffee beans from around the receiving section 442. Thereafter, the conveyor 41 is stopped, and the shutter section 443 and the outlet opening / closing section 408 are completely returned to the closed state. However, roasted coffee beans may be bitten as shown in FIG.

  For example, when it is not confirmed that the shutter unit 443 and the outlet opening / closing unit 408 have returned to the closed state within a predetermined time, the processing unit 11a notifies the user of the occurrence of biting. Biting of roasted coffee beans is often eliminated by slightly widening the outlet 405a. Therefore, the outlet 405a (the cylindrical portion 401) may be slightly turned manually to slightly widen the outlet 405a. However, when the canister 40 is mounted on the mounting portion 44, the outlet forming portion 405 (tubular portion 401) cannot be rotated manually due to the engagement between the protrusion 405b 'and the groove 441a.

  Therefore, as shown in a state ST23 of FIG. 40, the user manually slides the slider 409 to the second position. As a result, the protrusion 405b 'is detached from the groove 441a, and the engagement between them is released. The outlet forming portion 405 (tubular portion 401) can be manually rotated to eliminate biting. Thereafter, the user manually returns the slider 409 to the first position, and instructs the operation unit 12 to restart the operation to the closed state. The processing section 11a drives the motor 41a to completely return the shutter section 443 and the outlet opening / closing section 408 to the closed state.

<Reception unit and collective transport path>
The storage device 4 may be provided with a receiving part at a site different from the mounting part 44, separately from the receiving part 442 for each mounting part 44. The configuration example will be described again with reference to FIG.

  In the example of FIG. 27, a receiving unit 42c different from the receiving unit 442 is provided. The receiving portion 42c is an opening formed in the front wall of the collective conveyance path 42. The user can put the roasted coffee beans into the collective transport path 42 by hand or using a funnel-shaped device from the receiving section 42c. The inserted roasted coffee beans are supplied by their own weight to the grinding device 5 from the outlet 42b, and the coffee beverage can be manufactured.

  The receiving portion 42c can be used, for example, when manufacturing a coffee beverage using special roasted coffee beans that are not contained in the canister 40. The production processing program used for producing such a special cup of coffee beverage may be selectable, or may be a production processing program that operates under the production conditions set by the user.

  As described above, in the present embodiment, the receiving unit 442 that receives the supply of the roasted coffee beans from the canister 40 and the receiving unit 42c that receives the supply of the roasted coffee beans are provided. It is possible to provide the beverage manufacturing apparatus 1 that can respond to individual needs by the receiving unit 42c while securing mass productivity of the coffee beverage.

  In the case of the present embodiment, the crushing device 5 (especially, coarse particles) is supplied from the receiving portion 42c rather than the supply route RT1 (see FIG. 27 and FIG. 34) from the receiving portion 442 to the crushing device 5 (especially, the coarse grinder 5A). The supply path RT2 to the grinder 5A) has a shorter path length. When the roasted coffee beans are thrown in from the receiving section 42c, they generally fall directly to the outlet 42b and are supplied to the crushing device 5. This makes it possible to more reliably supply the whole amount of the roasted coffee beans that have been input to the crushing device 5, thereby suppressing the waste of beans and the occurrence of measurement errors. The supply route RT2 is a route that joins in the middle of the supply route RT1. The structure can be simpler than the configuration in which completely independent paths are formed.

  The conveyor 41 does not exist on the supply route RT2, and therefore, the roasted coffee beans input from the receiving unit 42c is not automatically weighed. For this reason, a user can measure coffee freely, and can manufacture a coffee drink by throwing in a desired amount of roasted coffee beans from the receiving unit 42c. However, it is also possible to provide a mechanism for automatically measuring the roasted coffee beans on the supply route RT2.

  The collective transport path 42 of the present embodiment has its front wall inclined forward and upward, and is arranged in an inclined posture as a whole. By tilting, the roasted coffee beans can be easily received in the receiving section 42c, and the roasted coffee beans conveyed from the conveyor 41 can also be directed to the crusher 5.

  Since the receiving portion 42c is an opening, the condition of the conveyor 41 can be visually inspected via the receiving portion 42c. That is, the receiving part 42c can also be used as an inspection window.

  Hereinafter, another example of the collective conveyance path 42 and the receiving unit 42c will be described.

  In the example of FIG. 48, two receiving units 42c are provided. In this way, a plurality of receiving sections 42c may be provided. One receiving portion 42c is provided with a lid 42d which can be opened and closed by a hinge 42e. When not used, the receiving portion 42 is closed with the lid 42d to prevent foreign matter from entering the collective conveyance path 42. The portion where the hinge 42e is provided may be any one of the upper side, the lower side, the back side, and the front side of the lid 42d. The other receiving portion 42c is formed by a hopper-like tube member 42f.

  The pipe member 42f may be separable from the collective conveyance path 42 as shown in FIG. The opening 42g is a hole for attaching the pipe member 42f. The opening 42g can also be used as an inspection hole for visually inspecting the inside of the collective conveyance path 42 and the conveyor 41.

In the case of the configuration example in FIG. 28, only the portion on the front side of the broken line L11 may be visible from the outside of the housing 100 via the transmission portion 101.

  Further, regarding the pulverizing device 5, all or a part of the coarse-grain grinder 5 </ b> A and the fine-grain grinder 5 </ b> B may be visible from the outside of the housing 100 via the transmission part 101.

  Further with respect to the extraction device 3, all or a part of the extraction container 9 may be visible from the outside of the housing 100 via the transmission part 101. All or a part of the change of the posture of the extraction container 9 such as the reversing operation of the extraction container 9 and the horizontal movement of the extraction container 9 (container main body 90) in the front-rear direction are transmitted from the outside of the housing 100 via the transmission unit 101. It may also be possible to visually recognize it. The opening and closing of the first plug member (for example, 913) in the extraction container 9 may or may not be visible from the outside of the housing 100 via the transmission unit 101. The opening and closing of the second plug member (for example, 903) in the extraction container 9 may or may not be visible from the outside of the housing 100 via the transmission unit 101. The opening and closing of the lid unit (for example, 91) in the extraction container 9 may or may not be visible from the outside of the housing 100 via the transmission unit 101.

<Fifth embodiment>
Another configuration example of the extraction container 9 will be described. FIG. 59 is a cross-sectional view of the extraction container 9 of the present embodiment, and shows a state where the extraction container 9 is locked by the gripping member 821a. FIG. 60 is an explanatory diagram of a guide function for automatically centering the container body 90 and the lid unit 91.

  In the extraction container 9 of the present embodiment, a guide portion 911e and a guide portion 90g are provided on the flange portion 911c and the flange portion 90c, respectively. When the lid unit 91 closes the opening 90a, one of the guides 911e and 90g guides the other to automatically center the container body 90 and the lid unit 91.

  In the case of the present embodiment, the guide portion 911e is an annular groove formed over the entire circumference of the flange portion 911c. The cross-sectional shape of this groove is triangular and opens downward (toward the container body 90). The guide portion 90g is an annular rib formed over the entire circumference of the flange portion 90c. The rib protrudes upward (toward the lid unit 91) from the flange portion 90c, and is inclined corresponding to the inclination of the inner surface of the guide portion 911e.

  FIG. 60 illustrates a case where the lid unit 91 closes the opening 90a from a state where it is separated from the opening 90a. In the case of the example shown in the figure, the lid unit 91 is shifted from the center line CLc of the container main body 90 by a very small amount. Note that the center of the lid unit 91 is the axis of the shaft 913a.

  As shown in FIG. 60, when the lid unit 91 is displaced from the center line CLc of the container main body 90, when the flange portion 911c and the flange portion 90c are overlapped, the guide portion 90g is inclined radially inward of the guide portion 911e. And at least one of them is slightly displaced laterally by the guide so that the center of the lid unit 91 is aligned with the center line CLc of the container body 90. As a result, the container body 90 and the lid unit 91 are automatically centered.

  In the present embodiment, the guide portion 911e is a groove, and the guide portion 90g is a rib. However, the relationship may be reversed. Further, the shapes of the guide portion 911e and the guide portion 90g can be appropriately selected.

  In the case of the present embodiment, the cross-sectional shape of the gripping member 821a is rectangular as in the example of FIG. 17, and the upper inner surface US forming the upper side of the cross-sectional shape and the lower inner surface LS forming the lower side of the cross-sectional shape are mutually separated. Parallel. In the locked state, the upper inner surface US contacts a part (contact surface) 911c 'of the upper surface of the flange portion 911c, and the lower inner surface LS contacts a part (contact surface) 90c' of the lower surface of the flange portion 911c. In the locked state, in the case of the present embodiment, the upper inner surface US, the lower inner surface LS, and the contact surface 911c 'The contact surface 90c' is parallel to each other and orthogonal to the center line CLc. When the inside of the extraction container 9 is pressurized, a force acts on the lid unit 91 and the container main body 90 in the vertical direction (more precisely, in the direction of the center line CLc) to separate them. Since the upper inner surface US, the lower inner surface LS, and the contact surface 911c 'are parallel to each other, a component force in a direction in which the pair of gripping members 821a is opened right and left acts as a component force of the separating force. The lock state can be more reliably maintained.
