Japanese Patent Publication No. 8-24851 (page 3, Fig. 1) Japanese Patent No. 2798079 (second page, FIG. 1)

  In automatic rice milling equipment, it is common for rice milling and polishing to be performed automatically for a certain period of time by inserting predetermined coins into the operation panel. It becomes an overcrowded arrangement configuration in which the devices of the operation stroke are arranged, and the maintainability and the like are easily hindered. In addition, in the form in which the charge tank for storing the polished rice is disposed above the rice milling apparatus, it is necessary to add a lift and the like having a high head, which is further complicated.

  The invention according to claim 1 is an automatic rice milling apparatus provided with a rice milling apparatus 11 that circulates through a rice milling chamber a plurality of times to mill brown rice and polish the rice, and is provided with a charge tank 14 in the middle of the circulation path. A switching means to switch to the charge tank side or product hopper side is provided on the discharge path side, and in the initial stage of polished rice and polished rice, the unpolished rice and unpolished rice are switched to the charge tank side, so that the initial circulation of polished rice and polished rice is temporarily stored. It is configured to return the polished rice and polished rice to the polished rice room in the process of finishing the polished rice and polished rice. Unpolished rice conveyed from the unpolished rice hopper 4 is received by the milled rice tank 12 and supplied to the milling apparatus 11 to perform milling. In the rice milling process alone, the milled rice at the initial stage of rice milling is stored in the charge tank 14 for a small amount, and then returned to the rice milling tank 12 for circulation. Other polished rice is taken out to the product hopper 5. Further, the white rice in the final stage of the rice polishing can be stored in the charge tank 14 and then returned to the rice polishing tank 12 and taken out to the product hopper 5 while circulating rice.

  In addition, when the polishing process is performed after the milling, the milled rice at the initial stage of the milling process is circulated and supplied to the milled tank 12 through the charge tank 14 to eliminate milling unevenness, and the subsequent charge tank 14 The rotation of the feeding valve 15 is stopped, and the white rice discharged from the rice milling apparatus 11 is stored in the charge tank 14. When the rice milling action is completed, the process is switched to the rice polishing process and the feed valve 15 of the charge tank 14 is driven to reduce the stored white rice in the charge tank 14 to the rice milling tank 12 to perform the rice polishing action. The rice is taken out to the product hopper 5. In the final process of the polishing, part of the polishing can be reduced to the milled rice hopper 5 via the charge tank 14 to eliminate unevenness of the polishing.

  The invention according to claim 2 is configured to automatically perform rice polishing and rice polishing for a certain period of time by inserting a predetermined coin into the operation panel, and the charge tank 14 is configured to store the brown rice hopper or the amount of coins. It is characterized in that the total amount of polished rice per predetermined unit price is set to a storable capacity. Although the rice milling or polishing action is performed as described above, the capacity of the charge tank 14 can accommodate the whole amount of the rice milling target amount supplied from the brown rice tank to the maximum. When the rice is polished, it is possible to supply the polished rice to the charge tank 14 with a single switching, or to switch to the polishing process.

  The invention according to claim 3 is a case where the polished rice is returned to the rice milling room in the polishing process, and the supply of white rice from the rice polishing tank 12 to the rice milling apparatus 11 is completed at the time of the rice polishing from the charge tank. It is characterized by the fact that a predetermined time required until the polished rice in the charge tank 14 is circulated and supplied to the rice milling apparatus 11 is passed.

  Therefore, when performing the rice milling and the rice polishing treatment as described above, a part or all of the polished rice is stored in the charge tank 14 and fed out by the feeding valve 15 to be returned to the rice milling apparatus 11. During the processing, the polishing rice is fed out continuously after a predetermined time has elapsed since it is determined that the supply of the white rice to the rice milling apparatus 11 has ended. During this time, even if there is no supply rice in the rice milling apparatus 11, the rice milling action is not stopped. When this predetermined time has elapsed, the polished rice in the charge tank 14 is reduced and circulated and supplied to the rice milling apparatus 11.

  The invention according to claim 4 is characterized in that the predetermined time is provided so as to be changeable according to the supply amount of brown rice, a usage fee or the like. Since polished rice and polished rice differ depending on the supply amount of brown rice, usage fees, and the like, the time for circulating supply from the charge tank 14 to the rice milling apparatus 11 also changes. For this reason, a predetermined time, which is the supply time of white rice fed out from the charge tank 14, is supplied to the brown rice by the supply amount of brown rice set at the time of rice polishing, the usage fee charged for the rice polishing, etc. Change and control according to the amount and usage fee.

  According to the first aspect of the present invention, when the rice milling process and the rice polishing process are performed by the rice milling apparatus 11, all or a part of the rice milling and rice polishing discharged from the rice milling apparatus 11 is a single charge tank 14. Therefore, it is possible to carry out circulation rice polishing and rice polishing action by storing or feeding and reducing the amount of the charge tank 14, so that the configuration can be simplified by sharing the charge tank 14.

  In the invention according to claim 2, the capacity of the charge tank 14 is formed large, but can be unified, and therefore can be shared with the feeding valve 15, the rice milling machine 10 and the like. In addition, it is possible to shift from the circular milled rice to the initial circular milled rice as it is, so that the processing efficiency can be improved.

  In the invention according to claim 3, when the white rice in the charge tank 14 is circulated to the rice milling apparatus 11 for polishing, the lower limit sensor 26 detects that the brown rice has been supplied to the rice milling apparatus 11. Since the stop control of the feeding valve 15 is performed when a predetermined time has passed after that, a special sensor for detecting whether or not the white rice in the charge tank 14 is less than a predetermined amount is unnecessary. It can be simplified.

  In the invention according to claim 4, the predetermined time set as the feeding time of the white rice from the charge tank 14 as described above is set according to the brown rice supply amount, the usage fee, etc. that are set and supplied in advance when the rice is polished. Since the change adjustment control is performed, it is possible to set the masking time (non-operation time) according to the small-scale rice polishing and the standard polishing rice, and the start time is appropriately set.

  Regarding the embodiment based on the drawings, an automatic rice milling machine that supplies a predetermined amount of brown rice for rice milling and coins required for the rice milling or rice milling automatically is equipped with various kinds of equipment for rice milling and rice polishing. The machine room 1 to be accommodated and the operation room 3 partitioned by the partition wall 2 are configured as a rice mill house H in the form of a small simple assembly house. In this partition wall 2, a brown rice hopper 4 for feeding brown rice, a product hopper 5 for receiving polished rice or polished white rice, and a rice milling and polishing operation are set. An operation panel 6 or the like having a coin roll box for performing is arranged. The machine room 1 is provided with a feeding valve 7 for feeding out the brown rice of the brown rice hopper 4 and is connected to a stone lifting elevator 8. This stone removal elevator 8 is put on a stone removal device 9 that performs a stone removal action. The stone removing device 9 sorts and removes gravel and foreign matters in the brown rice. The brown rice that has flowed down through the stone removing device 9 can be raised by a rice milling elevator 10 driven by a motor M2 and supplied to a rice milling (brown rice) tank 12 above the rice milling device 11. The rice milling device 11 is disposed at the upper part on the back side of the product hopper 5 so that the white rice extruded from the rice milling chamber port 13 flows down to the product hopper 5 below the front surface or flows down to the side charge tank 14. Can do. This charge tank 14 has a feeding valve 15 driven by a motor M3 at the bottom, and by this rotation, white rice in the charge tank 14 can flow to the rice mill elevator 10 and be reduced and supplied to the rice milling tank 12.

  The rice milling apparatus 11 is configured in a rice milling chamber 18 having a rice milling trochanter 16 driven by a motor M1 and having a rice milling net 17 on the outer periphery. An auger portion 19 is formed at the base of the rice milling trochanter 16 to receive the brown rice flowing from the rice milling tank 12 and push it into the rice milling chamber port 13 of the rice milling chamber 18. A resistance plate 20 is elastically provided at the rice milling chamber entrance 13 so as to be closed by a weight 21 or the like, and this resistance plate is moved while the brown rice in the rice milling chamber 18 is transferred and rubbed by the rotation of the rice milling trochanter 16. The rice is milled by extrusion against 20 pressures. The weight 21 can be moved back and forth with respect to the arm 23 protruding from the upper shaft 22 of the resistance plate 20 to change the pressure for closing the rice milling chamber port 13 of the resistance plate 20 to determine the degree of rice polishing. . In addition, regardless of the weight 21, by making the resistance plate 20 fully open (no resistance), the rice polishing action can be performed with almost no rice milling action. A shooter 24 is provided below the rice milling chamber port 13 to guide it down to the product hopper 5. A switching valve 25 is provided in the middle of the shooter 24 to guide the white rice flowing down into the charge tank 14.

  The rice milling action can be performed by keeping the resistance plate 20 in a closed state and supplying brown rice from the rice mill elevator 10 to the rice milling tank 12. Is stored in the charge tank 14, and the resistance plate 20 is opened after the rice milling action, and the white rice in the charge tank 14 is fed out by driving the feeding valve 15 and returned to the rice milling tank 12 through the rice milling elevator 10. Let it be done by feeding.

  The amount of brown rice that can be fed and polished at a time is limited by the amount of brown rice supplied to the brown rice hopper 4, the amount of coins to the operation panel 6, etc. The capacity of the charge tank 14 is set so that the total amount of polished rice corresponding to the maximum supply amount of brown rice can be stored. For example, it is set to a capacity that can accommodate 30 kg packed brown rice. The rice milling tank 12 is provided with a lower limit sensor 26 for detecting a state in which the brown rice in the tank 12 is supplied into the rice milling chamber 18 and almost disappeared. This is a standard for discriminating the start timing of circulating white rice supply at the end of rice.

  The rice milling and polishing operations are performed by setting or specifying from the operation panel 6, but at the time of the rice milling operation, the resistance plate 20 is in a state of closing the rice milling chamber opening 13 and gives a predetermined rice milling extrusion resistance. . When the brown rice supplied from the brown rice hopper 4 is supplied to the milled rice tank 12 through the stone punching elevator 8, the stone punching device 9, the rice milling elevator 10, etc., the lower limit sensor 26 is turned on and the rice milling device 11 is turned on. The rice is polished in the rice milling chamber 18 and extruded from the milling chamber port 13 to the shooter 24. At this time, for about 30 seconds from the start of milling, the switching valve 25 is switched so that the milled rice flows down from the shooter 24 into the charge tank 14, and the feeding valve 15 is driven. For this reason, since the rice milling pressure in the rice milling chamber 18 is low at the start of rice milling, unmilled rice grains are produced and collected into the charge tank 14 and then returned to the rice milling tank 12 to be polished. When 30 seconds have elapsed after the start of the rice polishing, the rotation of the feeding valve 15 is stopped. About 15 seconds after the rotation is stopped, the switching valve 25 is switched so that the white rice flowing down the shooter 24 flows into the product hopper 5. In this way, the white rice polished by the rice milling apparatus 11 is taken out to the product hopper 5 and subjected to processing such as bagging A.

  When all the brown rice in the milled rice tank 12 is supplied into the milled rice chamber 18 at the end of the milled rice, the lower limit sensor 26 is turned OFF and the feeding valve 15 of the charge tank 14 is driven for a certain time. The white rice in the charge tank 14 that has been stored for about 15 seconds due to the stop of the feeding valve 15 is reduced and supplied as circulating white rice to the milled rice tank 12 through the elevator 10, and the remaining rice in the milled rice chamber 18 is pushed out and polished. It is something to be made. At this time, even if the brown rice in the rice milling tank 12 decreases and the lower limit sensor 26 is turned off, the rice milling control is not stopped and the rice milling action can be continued within a predetermined time. This predetermined time (masking time) is started approximately 5 seconds before the lower limit sensor 26 is turned off, and is approximately the time required for the white rice in the charge tank 14 to be reduced and supplied again to the rice milling apparatus 11 as circulating white rice. The corresponding time length is set, and during this predetermined time, even if the lower limit sensor 26 is OFF, this OFF is ignored and the rice milling control is continued. For this reason, even if the white rice in the charge tank 14 is delayed due to a bridge phenomenon or the like, or even if there is a transport delay in the transport path from the feed valve 15 to the milling elevator 10 or the like, the unpolished rice grains remain in the milling chamber 18. This eliminates stopping the rice milling action in the state.

  The predetermined time (masking time) is set as a non-operation time of the rice milling control. Even if it is detected that the lower rice sensor 12 of the brown rice tank 12 is turned off and the brown rice is exhausted, this is ignored. This is to maintain and continue the operation of rice milling control. Here, by setting a masking time corresponding to the usage fee so that the lower limit sensor 26 does not remain in the OFF state after the predetermined time has elapsed, the ON timing of the lower limit sensor 26 is set due to an abnormality in the transport device or the like. Even if it is delayed, almost all of the white rice in the charge tank 14 can be discharged. In place of the lower limit sensor 26, a load sensor for detecting the rotational driving load of the rice milling trochanter 18 and detecting the presence or absence of brown rice in the rice milling tank 12 based on the magnitude of the load may be provided.

  Next, when polishing after rice polishing, the switching valve 25 is switched so as to guide the flow down to the charge tank 14, and the white rice polished by the rice polishing device 11 is driven for 30 seconds at the start of the rice polishing. After the valve 15 is stopped, the whole brown rice is polished and stored in the charge tank 14. When the brown rice in the milled rice tank 12 is milled and the lower limit sensor 26 is turned off, the feeding valve 15 is driven to feed the white rice in the charge tank 14. When the lower limit sensor 26 detects that the brown rice has run out and a predetermined time has elapsed, the white rice in the charge tank 14 is reduced and supplied to the rice milling tank 12 through the rice milling elevator 10 and is subjected to a rice polishing action in the rice milling chamber 18.

  At this time, the polished rice remaining rice in the previous stroke is pushed out by the reduced white rice supplied, but is maintained so that the switching valve 25 flows down to the charge tank 14 for about 30 seconds at the start of polishing. When 30 seconds have elapsed, the switching valve 25 is switched to guide the flow down to the product hopper 5 side, and the polished rice is taken out to the product hopper 5. When all of the white rice in the charge tank 14 is returned to the milled rice tank 12 and the lower limit sensor 26 is turned off, the rice polishing operation control is continued within the predetermined time, and the switching valve 25 is temporarily connected to the charge tank 14 side. The milled rice is reduced and supplied to the milled rice tank 12 through the feed valve 15 and the milling lift 10 and the like, and the milled rice grains in the milling chamber 18 are extruded as auxiliary milled rice. Is.

  The polished rice processed in the rice milling chamber 18 in this way is switched so as to be guided to flow down to the product hopper 5 of the switching valve 25, and is all taken out to the product hopper 5.

  Further, when only a part of the amount of brown rice supplied to the brown rice hopper 4 is polished, the amount of white rice to be switched and accommodated in the charge tank 14 can be selected. The excess milled rice guided and accommodated in the charge tank 14 by switching the switching valve 25 is taken out to the product hopper 5 by switching the switching valve 25. After this rice polishing, the white rice in the charge tank 14 is reduced and supplied to the rice milling tank 12 to perform the rice milling action.

  In the automatic rice milling apparatus, a trial button 27 is provided on the operation panel 6 (FIG. 5), and when the user selects the trial button 27 before using the grinding course to be polished, a small amount of brown rice is taken in and polished. Processing is performed. At this time, the usage fee is reduced by one unit price, but the remainder of the operation time of the feeding valve 15 is added when the final course is selected. If the user is satisfied with the Kengo course, continue the Kensei process by selecting the Kenkyu course button. If you don't like it, add the operating time and process it in the rice milling course. It is possible to re-select the course even if the rice grains are easy to break due to the nature of the rice or the user does not like it.

  This selection button includes a selection button 28 for a polished rice course, a selection button 29 for a polished rice course, and selection buttons 30, 31, 32, etc. for selecting a degree of milling. It is possible to press the course selection button 28 to perform rice polishing and rice polishing. Alternatively, if the test course selection button 27 is pressed, the small amount of brown rice is polished and polished. In addition, when the selection button 30 of the milled rice course is pressed, the milling degree of the upper white rice is finished, the standard milling degree is obtained with the selection button 31, and the milling degree of 8 minutes can be designated with the selection button 32.

The study course can be started by selecting only the study button 28, but by pressing the finish button 33, 34, or 35 after the start, the pressure adjustment during the study process can be selected. The rice milling course is started by pressing the rice milling course button 29 and the finishing button 30, 31, or 32, and can be polished with a desired degree of milling.

  You can also select finishes for the Kenken course. When old rice is introduced, the rice grain breaks and loses its taste in the Ken rice course, and the amount of polished rice decreases significantly. In that case, by selecting a finish button, the pressure during polishing can be reduced to prevent grain cracking. Alternatively, it can be configured to be activated by designating “upper white” by operating only the rice milling button 29, and switching to other milling degrees such as “standard” and “8 minutes” after the start.

  Based on FIGS. 2 and 8, the partition wall 2 is provided with a confirmation window 36 through which the inside of the charge tank 14 can be seen.
