By the way, in the technical examples of Patent Document 1 and Patent Document 2, it is preferable that the time required for delivery of individual articles can be shortened. However, in the parts warehouse, when the individual reels are delivered separately, the delivery operation becomes frequent, so that the operator's response is frequent and troublesome. Further, each time the reel is delivered, it takes time and effort to take out the reel and transport it to the parts mounting machine or the parts mounting line. The reel is not always directly conveyed to the component mounting machine, but may be conveyed to the setup work area and loaded into the feeder device.

In this specification, it is an issue to be solved to provide a parts warehouse capable of streamlining the reel unloading operation and the subsequent transportation work.

In this specification, a warehouse housing, a reel provided in the warehouse housing and wound with a carrier tape for accommodating a plurality of parts, and a carrier case capable of accommodating the plurality of the reels are loaded and unloaded. The reel and the carrier are provided between the opening, a storage unit provided inside the warehouse housing and having a plurality of storage positions for storing the reel and the carrier case, and the warehousing / delivery port and the storage position. A parts warehouse including a transport operation unit for transporting a case and a storage operation unit for storing a plurality of the reels in the carrier case inside the warehouse housing is disclosed.

In the parts warehouse disclosed in this specification, a plurality of reels can be stored in a carrier case inside the parts warehouse. Therefore, by delivering the carrier case, a plurality of reels can be delivered at the same time, and the delivery operation can be made more efficient. Further, since the carrier case can be conveyed to the place where the subsequent process is performed, a plurality of reels can be conveyed at the same time, so that the transfer work can be made more efficient. In addition, since the reel can be supplied quickly, it contributes to the improvement of the production efficiency of the substrate product.

1. 1. Equipment Configuration of Parts Warehouse 1 of the First Embodiment The equipment configuration of the parts warehouse 1 of the first embodiment will be described with reference to FIGS. 1 to 4. The parts warehouse 1 stores, stores, and exits a reel 81 on which a carrier tape for accommodating a plurality of parts is wound and a carrier case 85 capable of accommodating the plurality of reels 81. The reel 81 is used in the component mounting line 9 in which one component mounting machine or a plurality of first to fourth component mounting machines (91 to 94) are lined up (see FIG. 5).

As shown in FIGS. 2 and 3, the reel 81 has a disk shape and has a through hole 82 at the center thereof. The reel 81 has a part type label 83 affixed to it when it is procured. The part type label 83 indicates, for example, the type and characteristics of the parts contained in the carrier tape, the expiration date, the width dimension of the carrier tape, the size of the reel 81, the production lot number, and the like. The part type label 83 is produced and affixed by the part supplier. As the part type label 83, a bar code, a two-dimensional code, a number string, or the like is used.

The manufacturer of the board product manages the procured reel 81 by attaching the reel identification label 84 later. The reel identification label 84 identifies the individual reel 81. The reel identification label 84 may be associated with incidental information desired by the manufacturer. As the incidental information, the information possessed by the part type label 83 can be exemplified. According to this, if the reel identification label 84 is read in the subsequent operations and operations, it is not necessary to read the part type label 83 each time.

As shown in FIGS. 3 and 4, the carrier case 85 is formed in a box shape that opens upward. The depth of the carrier case 85 is appropriately set according to the number of reels 81 to be stored. At the center of the carrier case 85, a shaft rod 86 extending in the vertical direction is provided. The shaft rod 86 engages in the through holes 82 of the plurality of reels 81. As a result, the carrier case 85 stores the plurality of reels 81 in an vertically stacked manner. A case identification label 87 is affixed to the collar of the upper edge of the carrier case 85. The case identification label 87 identifies the individual of the carrier case 85. The carrier case 85 may have a shape different from the above, and for example, the shaft rod 86 may be omitted in a cylindrical shape that opens upward.

The parts warehouse 1 is composed of a warehouse housing 2, an entry / exit port 3, a reel storage unit 4R, a case storage unit 4C, a holding / moving unit 5, a warehouse control unit 7 (see FIG. 5), and the like. The warehouse housing 2 is formed in a rotationally symmetric shape having a vertical axis AX. In the first embodiment, as shown in FIGS. 1 to 3, the warehouse housing 2 is formed in a vertical cylindrical shape. The inside of the warehouse housing 2 has a three-stage structure consisting of an upper stage, a middle stage, and a lower stage.

Seven reel storage units 4R are provided side by side in the circumferential direction of the upper stage of the warehouse housing 2. The entrance / exit 3 and the six reel storage units 4R are provided side by side in the circumferential direction of the middle stage of the warehouse housing 2. Four reel storage units 4R and three case storage units 4C are provided side by side in the circumferential direction of the lower part of the warehouse housing 2. The positions of the three case storage units 4C are directly below the entrance / exit 3 and on both the left and right sides thereof. Therefore, a total of 17

reel storage units

4R and 3 case storage units 4C are provided. The number of each storage unit (4R, 4C) may be other than the above. Further, the arrangement and structure of the storage units (4R, 4C) inside the warehouse housing 2 can be variously deformed.

The entrance / exit 3 is arranged at an intermediate height in front of the warehouse housing 2. The warehousing / delivery port 3 is a place where the reel 81 and the carrier case 85 are carried in and out. By locating the warehousing / delivery port 3 at an intermediate height, the average value of the transport distances to all the storage shelves 42 is minimized. Therefore, the average value of the time required for warehousing and the average value of the time required for warehousing are also minimized. The warehousing port may be arranged at the intermediate height of the front surface of the warehouse housing 2, and the warehousing port may be arranged separately at the intermediate height of the rear surface of the warehouse housing 2. The entrance / exit 3 is composed of an opening 31, a stand 32, a camera 34, a label production / sticking machine 35, and the like.

The opening 31 is formed in a horizontally long rectangle at an intermediate height position on the front surface of the warehouse housing 2. A stand 32 is provided behind the lower edge of the opening 31. The stand 32 is composed of two plate members separated from each other on the left and right sides. The two plate members are arranged at a slight inclination angle so that the front side close to the opening 31 is low and the back side is high. The lower arm 562 of the grip portion 56, which will be described later, can enter between the two plate members. A positioning member 33 extending in the left-right direction is provided on the upper portion in front of the stand 32. The positioning member 33 stabilizes the mounting position of the reel 81 and the carrier case 85 mounted on the stand 32.

The camera 34 is arranged behind the upper edge of the opening 31, and images are taken downward. The camera 34 has a light source for illumination and has a function of automatically adjusting imaging conditions according to an imaging object. The camera 34 takes an image of the reel 81 on the stand 32 and reads the part type label 83 and the reel identification label 84. Further, the camera 34 takes an image of the carrier case 85 on the stand 32 and reads the case identification label 87. Further, the camera 34 may have a function of discriminating the sizes of a plurality of types of the reel 81 and the carrier case 85, and confirming the mounting position and orientation.

The label production and sticking machine 35 is arranged further back than the camera 34 on the upper edge of the opening 31. The label production sticking machine 35 produces a reel identification label 84 according to a command. The label production / sticking machine 35 further moves the produced reel identification label 84 to the lower sticking execution position and sticks the produced reel identification label 84 to the reel 81 located at the lower side.

The internal configuration of the 17 reel storage units 4R is almost the same. Each of the reel storage units 4R is composed of a storage container 41 and five storage shelves 42. The storage container 41 is formed in a box shape that opens laterally toward the axis AX. The five storage shelves 42 are arranged at equal intervals in the vertical direction inside the storage container 41. The storage shelf 42 is made of two plates separated to the left and right like the stand 32, and has the same inclination angle as the stand 32. The storage shelf 42 is a form of a storage position for storing the reel 81. Since the storage shelf 42 and the stand 32 have an inclination angle, the reel 81 is prevented from slipping due to the influence of vibration or the like.

The parts warehouse 1 stores reels 81 in a total of 85 storage shelves 42, which are 17 reel storage units 4R. The actual parts warehouse can store a larger number of reels 81. Each of the storage shelves 42 is assigned an identification number and managed. The identification number is assigned by, for example, a combination of a number for specifying the storage container 41 and a number indicating the arrangement height of the storage shelf 42.

The internal configuration of the three case storage units 4C is almost the same. Each of the case storage units 4C is composed of a storage container 41 having the same shape as the reel storage unit 4R and two storage shelves 42. The height positions of the two storage shelves 42 correspond to the bottom and the third storage shelves 42 from the bottom of the reel storage unit 4R. Therefore, the vertical separation distance of the storage shelf 42 is increased, and the storage shelf 42 can store the tall carry case 85. A maximum of six carrier cases 85 are stored in the three case storage units 4C. Each of the storage shelves 42 is assigned an identification number and managed in the same manner as the reel storage unit 4R.

The storage shelf 42 is removable from the storage container 41. The work of attaching and detaching the storage shelf 42 is performed through an openable and closable hand hole (not shown) provided in the warehouse housing 2. Therefore, the reel storage unit 4R can be changed to the case storage unit 4C, and vice versa. Further, the storage container 41 can be moved in position or replaced with a spare part.

The holding / moving unit 5 moves inside the warehouse housing 2 while holding the reel 81 and the carrier case 85. The holding / moving unit 5 also serves as a transport operation unit and a storage operation unit. The transport operation unit transports the reel 81 and the carrier case 85 between the warehousing / delivery port 3 and the storage shelf 42 of the storage unit (4R, 4C). The storage operation unit stores a plurality of reels 81 in the carrier case 85 inside the warehouse housing 2.

The holding and moving portion 5 is composed of two elevating shafts 51, a bearing portion 52, a rotation drive portion 53, an elevating rotation portion 54, an elevating drive portion 55 (see FIG. 5), a grip portion 56, and the like. The two elevating shafts 51 extend in the vertical direction and are arranged symmetrically with the axis AX interposed therebetween. In FIG. 1, the two elevating shafts 51 overlap in the front and back directions of the paper surface, and only one is displayed.

The bearing portion 52 is arranged on the bottom plate 21 of the warehouse housing 2. The bearing portion 52 supports the lower ends of the two elevating shafts 51, and allows the two elevating shafts 51 to revolve around the axis AX. The rotation drive unit 53 is arranged under the top plate 22 of the warehouse housing 2. The rotation drive unit 53 supports the upper ends of the two elevating shafts 51, and revolves the two elevating shafts 51 around the axis AX.

The elevating rotation unit 54 is arranged in a region where the storage unit (4R, 4C) in the center of the warehouse housing 2 does not exist, and is attached across the two elevating shafts 51. As the two elevating shafts 51 revolve, the elevating rotating portion 54 rotates around the axis AX. Further, an elevating drive unit 55 is attached to the elevating rotation unit 54. The elevating rotation unit 54 is driven by the elevating drive unit 55 and elevates and descends along the two elevating shafts 51. The elevating and rotating portion 54 is formed long in the front-rear direction (the left-right direction in FIG. 1), and has the same inclination angle as the stand 32 and the storage shelf 42.

The grip portion 56 is provided on the elevating and rotating portion 54 so as to be movable in the radial direction. The grip portion 56 is composed of a grip body portion 561, a lower arm 562, an upper arm 563, and a grip drive portion 564. The gripping body portion 561 can move back and forth on the upper surface of the elevating and lowering rotating portion 54. As a result, the entire grip portion 56 moves back and forth in the radial direction about the axis AX. The lower arm 562 is attached to the lower part of the gripping main body portion 561 and extends forward. The upper arm 563 is attached at a position higher than the lower arm 562 of the gripping main body 561, and extends forward. The upper arm 563 can be raised and lowered with respect to the gripping main body portion 561. The length of the upper arm 563 is shorter than that of the lower arm 562. The lower arm 562 and the upper arm 563 have the same inclination angle as the stand 32 and the storage shelf 42, and are parallel to each other.

As shown in FIG. 1, when the gripping main body portion 561 is located at the rear end of the elevating rotation portion 54, the tip of the lower arm 562 does not protrude from the elevating rotation portion 54. Therefore, the lower arm 562 does not interfere with the rotation operation and the elevating operation of the elevating rotating portion 54. When the gripping main body portion 561 moves in front of the elevating rotation portion 54, the lower arm 562 protrudes from the elevating rotation portion 54 and enters between the two plate members constituting the stand 32 and the storage shelf 42. ..

The gripping drive unit 564 is provided above the gripping main body unit 561. The gripping drive unit 564 drives the upper arm 563 up and down. As a result, the vertical separation distance between the lower arm 562 and the upper arm 563 changes. Therefore, the lower arm 562 and the upper arm 563 can grip the reel 81 and the carrier case 85 placed on the stand 32 and the storage shelf 42 from above and below, and can be opened. It is also possible to adopt a configuration in which the gripping body portion 561 does not move and the lower arm 562 and the upper arm 563 expand and contract in the front-rear direction.

2. Configuration related to control of parts warehouse 1 Next, a configuration related to control of parts warehouse 1 will be described. As shown in FIG. 5, the parts warehouse 1 includes a warehouse control unit 7. Further, as shown in FIG. 2, an operation display panel 79 is provided on the upper side of the entrance / exit 3 on the front surface of the warehouse housing 2. The operation display panel 79 includes an operation unit operated by the operator and a display unit that displays information toward the operator. The operation display panel 79 functions as a man-machine interface for exchanging information between the operator and the warehouse control unit 7.

The warehouse control unit 7 is a computer device that has a CPU, a storage unit, and the like and operates by software. The warehouse control unit 7 controls the camera 34 and the label production / pasting machine 35. Further, the warehouse control unit 7 controls the rotation drive unit 53, the elevating drive unit 55, the gripping main body unit 561, and the gripping drive unit 564 of the holding / moving unit 5. Further, the warehouse control unit 7 includes three control function units that comprehensively control the operation of the parts warehouse 1, that is, a transport control unit 71, a storage control unit 72, and a storage position control unit 73.

The warehouse control unit 7 is communicated with the line control unit 99. The line control unit 99 is communicated and connected to the first to fourth component mounting machines (91 to 94) constituting the component mounting line 9, respectively. The component mounting line 9 is a part of a production line for mass-producing substrate products by mounting components on a substrate. The line control unit 99 manages the progress of the mounting work of the first to fourth component mounting machines (91 to 94). Further, the line control unit 99 manages the change of the type of the substrate product to be produced and the type of the original substrate.

The transport control unit 71 controls the holding / moving unit 5 to perform the warehousing operation and the warehousing operation. More specifically, the transport control unit 71 first recognizes that the reel 81 and the carrier case 85 have been carried into the warehousing / delivery port 3. The presence of the reel 81 and the carrier case 85 is automatically recognized by the periodic imaging operation of the camera 34, or is recognized by the input operation to the operation display panel 79 of the operator.

Next, the transport control unit 71 designates the identification number of the storage shelf 42 and instructs the holding / moving unit 5 to perform transport and storage (command for warehousing operation). The identification number of the storage shelf 42 is specified by the transport control unit 71 autonomously, or according to an input operation on the operation display panel 79 of the operator. Thirdly, the transport control unit 71 stores the reel identification label 84 of the stored reel 81 or the case identification label 87 of the carrier case 85 in association with the identification number of the storage shelf 42.

Further, the transport control unit 71 receives a request from the line control unit 99 and a request input to the operation display panel 79. The transport control unit 71 identifies the required reel identification label 84 of the reel 81 or the case identification label 87 of the carrier case 85, and further identifies the identification number of the storage shelf 42, as required. Next, the transport control unit 71 designates the identification number of the storage shelf 42, and instructs the holding / moving unit 5 to transport the reel 81 or the carrier case 85 to the warehousing / delivery port 3 (command for warehousing operation). .. The control functions of the storage control unit 72 and the storage position control unit 73 will be described later.

3. 3. Details of the warehousing operation of the parts warehouse 1 Next, the details of the warehousing operation of the parts warehouse 1 will be described with reference to the time-series situations and operations of FIGS. 6 to 12 when the reel 81 is warehousing. Prior to the warehousing operation, the elevating rotation unit 54 is driven to a position facing the warehousing / delivery port 3, the gripping main body portion 561 is located at the rear end of the elevating rotation unit 54, and the upper arm 563 is driven ascending. Therefore, the distance from the lower arm 562 is widened.

At the beginning of the warehousing operation, the reel 81 is carried in and placed on the stand 32 as shown in FIG. The reel 81 is placed by an operator. Alternatively, the reel 81 may be automatically placed by the transfer robot. Next, the camera 34 performs an imaging operation (see reference numeral TP in FIG. 6), and reads the part type label 83 and the reel identification label 84 attached to the reel 81. Here, the reel 81 to which the reel identification label 84 is already attached is in use.

On the other hand, the reel 81 to which the reel identification label 84 is not attached is a new product. The warehouse control unit 7 sets an identification code on the new reel 81, and instructs the label production / sticking machine 35 to produce the reel identification label 84 corresponding to the identification code. The warehouse control unit 7 further stores the part type label 83 of the new reel 81 and the reel identification label 84 in association with each other. Upon receiving the command, the label production and sticking machine 35 creates the reel identification label 84 and moves it to the lower sticking execution position. This is the situation shown in FIG.

Next, as shown by the arrow M1 in FIG. 8, the transport control unit 71 advances the grip portion 56, causes the lower arm 562 to enter the lower side of the reel 81, and moves the upper arm 563 above the reel 81. Let it enter. Next, the transport control unit 71 raises the elevating and rotating unit 54 as shown by the arrow M2 in FIG. 9, and lowers the upper arm 563 as shown by the arrow M3. As a result, the lower arm 562 and the upper arm 563 grip the reel 81.

Next, as shown by the arrow M4 in FIG. 10, the transport control unit 71 retracts the grip portion 56 while raising the elevating and rotating portion 54. As a result, the reel 81 approaches the label production / sticking machine 35 and moves to a position immediately below the sticking execution position. Next, the warehouse control unit 7 instructs the label production and pasting machine 35 to attach the reel identification label 84. Upon receiving the command, the label production and sticking machine 35 attaches the reel identification label 84 to the reel 81 as shown by the arrow M5 in FIG. The position where the reel identification label 84 is attached does not have to be the position adjacent to the part type label 83.

Next, the transport control unit 71 further retracts the grip unit 56 as shown by the arrow M6 in FIG. As a result, the elevating and rotating unit 54 carries out the reel 81 from the warehousing / delivery port 3. The transport control unit 71 controls the holding / moving unit 5 so that the used reel 81 directly shifts from the situation of FIG. 9 to the situation of FIG. 12 without going through FIGS. 10 and 11. do.

After that, the transport control unit 71 drives the elevating and rotating unit 54 to a position facing the storage shelf 42 to which the identification number is designated, and advances the grip unit 56. As a result, the reel 81 reaches the storage shelf 42. The transport control unit 71 increases the separation distance between the lower arm 562 and the upper arm 563, and places the reel 81 on the storage shelf 42 for storage. As a result, the warehousing operation of the reel 81 is completed.

In the warehousing operation of the reel 81, the reel 81 is gripped by the storage shelf 42, and the reel 81 is opened by the warehousing / delivery port 3. In addition, the label production / pasting machine 35 is not used in the delivery operation. Further, the carrier case 85 is also subjected to the same warehousing and unloading operations. However, the difference is that the label production / sticking machine 35 is not used and that the separation distance between the lower arm 562 and the upper arm 563 is significantly increased.

4. Control functions of the storage control unit 72 and the storage position control unit 73 Next, the control functions of the storage control unit 72 and the storage position control unit 73 will be described. The storage control unit 72 controls the holding and moving unit 5 so that a plurality of reels 81, which are required as the mounting work progresses on the component mounting line 9, are stored in the carrier case 85. Further, the storage control unit 72 stores a plurality of reels 81 together in the carrier case 85 based on the order of the required reels 81. Here, the line control unit 99 predicts the order of the required reels 81 and transmits the prediction result to the warehouse control unit 7.

The storage control unit 72 controls the holding / moving unit 5 based on the received prediction result, and stores the plurality of reels 81 in the carrier case 85 in order. Specifically, the holding and moving unit 5 repeats an operation of gripping the reel 81 on the storage shelf 42 of the reel storage unit 4R, transporting the reel 81 to the upper part of the carrier case 85, opening the reel, and dropping the reel 81. Here, when the carrier case 85 can store, for example, four reels 81, the required first to fourth reels 81 are stored in the first carrier case 851 (see FIG. 13). Then, the required fifth to eighth reels 81 are housed in the second carrier case 852, and the required ninth to twelfth reels 81 are housed in the third carrier case 853.

Then, the first carrier case 851 is delivered first, then the second carrier case 852 is delivered, and the third carrier case 853 is delivered third. The delivered carrier cases (851, 852, 853) are transported to the component mounting line 9 by an operator or a transfer robot, and the reels 81 are taken out and used respectively. Alternatively, the delivered carrier cases (851, 852, 853) are conveyed to the setup work area, and the reels 81 are taken out and loaded into the feeder device. Then, this feeder device is transported to the component mounting line 9 for use.

In this way, in the storage based on the order of the required reels 81, the reels 81 required for the component mounting line 9 are reliably supplied. Therefore, the risk of production interruption due to parts shortage is reduced. When the required reel 81 does not exist in any of the storage shelves 42, the storage control unit 72 displays a message requesting the operator to store the reel 81 on the operation display panel 79. Further, with the delivery of the carrier cases (851, 852, 853), a vacancy is generated in the storage shelf 42 of the case storage unit 4C, so that a new carrier case 85 can be stored.

The storage position control unit 73 controls the holding / moving unit 5 so that the carrier case 85, which is scheduled to be delivered earlier, is stored in the storage shelf 42 closer to the entry / exit port 3. More specifically, the order of the storage shelves 42 near the warehousing / delivery port 3 is predetermined based on the length of the warehousing time required, not the physical distance. The time required for delivery depends on the rotation operation time and the elevating operation time of the elevating rotation unit 54. In the first embodiment, as shown in FIG. 13, the upper storage shelf 421 of the case storage unit 4C1 directly below the warehousing / delivery port 3 is the closest to the warehousing / delivery port 3, and the lower storage shelf 422 is the second. It is stipulated that it is close to the entry / exit port 3.

Then, the storage shelf 423 on the upper side of one case storage unit 4C2 that is removed from directly below the warehousing / delivery port 3 is defined as the third, and the storage shelf 424 on the upper side of the other case storage unit 4C3 that is removed from directly below is defined as the fourth. There is. Further, the lower storage shelf 425 of one case storage unit 4C2 is defined as the fifth, and the lower storage shelf 426 of the other case storage unit 4C3 is defined as the sixth.

In this case, the first carrier case 851 is stored in the nearest storage shelf 421, and the second carrier case 852 is stored in the second closest storage shelf 422. Then, the third carrier case 853 is stored in the storage shelf 423 closest to the third. Hereinafter, the fourth to sixth carrier cases 85 are stored in the storage shelves (424 to 426) closest to the fourth to sixth, respectively.

After the first carrier case 85 is delivered from the storage shelf 421, the storage position control unit 73 moves the second carrier case 852 of the storage shelf 422 to the storage shelf 421 in the spare time when the warehousing / delivery operation is not performed. .. Further, the storage position control unit 73 sequentially moves the third carrier case 853 of the storage shelf 423 to the storage shelf 422. Further, the storage position control unit 73 sequentially moves the fourth and subsequent carrier cases 85 to the storage shelf 42 near the warehousing / delivery port 3.

Further, for example, the four reels 81 required for the first component mounting machine 91 and the second component mounting machine 92 are housed in the first carrier case 85, and the third component mounting machine 93 and the fourth component mounting machine 94 are used. The required four reels 81 can be stored in the second carrier case 85. As described above, in the storage based on the arrangement positions of the first to fourth component mounting machines (91 to 94), mistakes are less likely to occur when the reel 81 is taken out from the carrier case 85 and used in the component mounting line 9. Moreover, since the work is easy, the workability is improved.

Furthermore, it is not always necessary to perform the warehousing operation in units of the carrier case 85. That is, when the required time of a certain reel 81 is significantly different from the required time of another reel 81, the transport control unit 71 can control the holding and moving unit 5 so that the reel 81 is delivered independently. can. In addition, the transport control unit 71 can immediately deliver the reel 81 that is urgently needed due to the occurrence of a trouble or the like. That is, by combining the unloading operation of the carrier case 85 and the unloading operation of the reel 81, the reel 81 can be provided elastically and in a timely manner.

Further, the storage control unit 72 uses the same carrier case 85 for a plurality of reels 81 required for each of the first to fourth component mounting machines (91 to 94) when the type of the board is changed in the component mounting line 9. The holding and moving unit 5 is controlled so as to be collectively stored in. In the setup change work when changing the type of the board on the component mounting line 9, it is usually necessary to replace a large number of reels 81. The storage control unit 72 can acquire information on the execution time of the setup change work and the type and number of required reels 81 from the line control unit 99.

Then, the storage control unit 72 controls the storage operation of the reel 81 in the carrier case 85 by the holding / moving unit 5 based on the acquired information. In this case, it is preferable to assign the carrier case 85 to each of the first to fourth component mounting machines (91 to 94). The number of carrier cases 85 to be allocated may be different for each of the first to fourth component mounting machines (91 to 94).

In the parts warehouse 1 of the first embodiment, a plurality of reels 81 can be stored in the carrier case 85 inside the parts warehouse 1. Therefore, by delivering the carrier case 85, a plurality of reels 81 can be delivered at the same time, and the delivery operation can be made more efficient. Further, since the carrier case 85 can be conveyed to the place where the subsequent process is performed, a plurality of reels 81 can be conveyed at the same time, so that the transfer work can be made more efficient. In addition, since the reel 81 can be supplied quickly, it contributes to the improvement of the production efficiency of the substrate product. In addition, it is possible to reduce the waiting time of the worker at the warehousing / delivery port 3.
