[0046] [Automated warehouses and elevator equipment] Fig. 5 is a perspective view showing the automatic warehouse 6 and the elevator device 7 according to the embodiment. Fig. 6 is a front view showing the automatic warehouse 6 according to the embodiment.

[0047] The automated warehouse 6 stores a plurality of tape reels 23. The elevator device 7 stores the plurality of tape reels 23 in the automated warehouse 6. Before being stored in the automated warehouse 6, an identifier 24 is assigned to each of the plurality of tape reels 23.

[0048] The tape reel 23 is stored in the automated warehouse 6 while being supported by the tray 30. The elevator device 7 performs an entry process for entering the tray 30 into the automated warehouse 6 and an exit process for removing the tray 30 from the automated warehouse 6.

[0049] 5 and 6, an intermediate storehouse 40 is disposed between the automatic storehouse 6 and the elevator device 7. The trays 30 before being taken out are temporarily stored in the intermediate storehouse 40. The automatic storehouse 6 and the intermediate storehouse 40 are connected by a cover 41.

[0050] The intermediate warehouse 40 has an entrance / exit 42 through which the trays 30 pass, and a shutter 43 that opens and closes the entrance / exit 42. The shutter 43 opens the entrance / exit 42 when the trays 30 are entering and leaving the warehouse, and closes the entrance / exit 42 when the trays 30 are not entering and leaving the warehouse. This suppresses temperature and humidity changes in the internal space of the intermediate warehouse 40.

[0051] 7 is a cross-sectional view showing an elevator device 7 according to an embodiment. The elevator device 7 has a frame 44, a lifting stage 45 that can lift and lower the tray 30 while supporting it, and a lifting mechanism 46 that lifts and lowers the lifting stage 45.

[0052] Moreover, the elevator device 7 has a side guide member 47 that is provided on the lift stage 45 and guides the side surface of the tray 30. The tray 30 is disposed inside the side guide member 47.

[0053] The trays 30 are stacked on the lifting stage 45. The component conveying device 9 can convey a plurality of stacked trays 30. The plurality of trays 30 conveyed by the component conveying device 9 are delivered to the lifting stage 45 in a stacked state. In addition, the plurality of trays 30 supported by the lifting stage 45 are delivered to the component conveying device 9 in a stacked state.

[0054] When the tray 30 is taken out from the automated warehouse 6, the warehouse control device 8 controls the lifting mechanism 46 so that the upper surface of the lifting stage 45 is positioned at the same height as the entrance / exit gate 42. The tray 30 present in the intermediate warehouse 40 is taken out from the intermediate warehouse 40 by a conveying mechanism (not shown) provided in the elevator device 7. The tray 30 taken out from the intermediate warehouse 40 passes through the entrance / exit gate 42 and is taken out from the intermediate warehouse 40. The tray 30 taken out from the intermediate warehouse 40 is placed on the lifting stage 45. When the tray 30 is placed on the lifting stage 45, the warehouse control device 8 controls the lifting mechanism 46 so that the lifting stage 45 is lowered by a distance equal to the height of the tray 30. By repeating the taking out of the tray 30 and the lowering of the lifting stage 45, multiple trays 30 are stacked on the lifting stage 45.

[0055] When storing the tray 30 in the automated warehouse 6, the warehouse control device 8 controls the lifting mechanism 46 so that the uppermost tray 30 among the multiple trays 30 stacked on the lifting stage 45 is positioned at the same height as the loading / unloading gate 42. The tray 30 is stored in the intermediate warehouse 40 by a conveying mechanism (not shown) provided in the elevator device 7. The tray 30 passes through the loading / unloading gate 42 and is stored in the intermediate warehouse 40. When the tray 30 is stored in the intermediate warehouse 40, the warehouse control device 8 controls the lifting mechanism 46 so that the lifting stage 45 rises by a distance equal to the height of the tray 30. By repeating the storing of the tray 30 and the rising of the lifting stage 45, the multiple trays 30 are sequentially carried out from the lifting stage 45.

[0056] The elevator system 7 also includes a reading device 33. The reading device 33 reads the identifier 24 of the tape reel 23 in the elevator system 7. The reading device 33 includes a camera. If the identifier 24 includes a barcode, the reading device 33 includes a barcode reader. If the identifier 24 includes an RFID tag or an RFID sticker, the reading device 33 includes an RFID reader.

[0057] [Parts conveying device] 8 is a perspective view showing a component conveying device 9 according to an embodiment. The component conveying device 9 includes a conveyor 50 having drive wheels 52, and a conveying cart 51 attached to the conveyor 50. The tray 30 is supported by the conveying cart 51. The conveying cart 51 is detachable from the conveyor 50. The conveyor 50 moves on its own with the conveying cart 51 connected thereto.

[0058] The transport cart 51 has a pair of side covers 53, a top cover 54 connecting upper ends of the pair of side covers 53, and driven wheels 55 provided on the lower part of the side covers 53. The transport machine 50 is disposed in a space formed by the pair of side covers 53 and the top cover 54.

[0059] The transport cart 51 is disposed on top of the top cover 54, and has a transport stage 56 supporting a plurality of trays 30, a front guide member 57 for guiding the front of the tray 30 supported by the transport stage 56, and a rear guide member 58 for guiding the rear of the tray 30. The front guide member 57 includes a pair of sub-guide members 57A and an opening / closing door 57B connected to one of the sub-guide members 57A. When the opening / closing door 57B is opened, the tray 30 passes between the pair of sub-guide members 57A and is transported out of or into the transport stage 56.

[0060] The tray 30 can move between the lift stage 45 and the transport stage 56 while being guided by a front guide member 57 and a rear guide member 58 .

[0061] [Warehouse control device] 9 is a functional block diagram showing a warehouse control device 8 according to an embodiment. The warehouse control device 8 controls the automated warehouse 6 and the elevator device 7. The warehouse control device 8 communicates with each of the management control device 4, the transport control device 10, the production control device 12, and the information terminal 26.

[0062] The warehouse control device 8 has a production plan data storage unit 61, an identification information acquisition unit 62, a warehousing command output unit 63, a request command acquisition unit 64, and a warehousing command output unit 65.

[0063] The production plan data storage unit 61 stores production plan data 71 that represents a production plan that is a plan for producing a product in the component mounting system 3. The production plan data 71 is transmitted from the management control device 4 or the production control device 12 to the warehouse control device 8 and stored in the production plan data storage unit 61.

[0064] 10 is a diagram illustrating an example of production plan data 71 according to an embodiment. The production plan data 71 includes a first column 71a for storing a production plan number indicating an execution sequence, a second column 71b for storing the names of parts to be used, and a third column 71c for storing the number of parts to be used.

[0065] The first row 71d of the production plan data 71 indicates that in the first production, "3" trays of parts with the part name "AAA" will be used.

[0066] The second line 71e of the production plan data 71 indicates that in the second production run after the first production run is completed, three trays of parts with the part name "BBB" will be used.

[0067] The third line 71f of the production plan data 71 indicates that in the third production run after the second production run is completed, three trays of parts with the part name "CCC" will be used.

[0068] 9 again, the identification information acquisition unit 62 receives the identification information of the delivered part C from the information terminal 26 of the receiving space 16. Here, it is assumed that a part named "AAA" is delivered to the receiving space 16 in tray "10", a part named "BBB" is delivered to tray "10", and a part named "CCC" is delivered to tray "10".

[0069] The storage command output unit 63 outputs a storage command to the automated warehouses 6, the elevator device 7, and the transport control device 10 to distribute the multiple trays 30 to the multiple automated warehouses 6 and store them in parallel (preferably simultaneously) based on the identification information and production plan data 71. In detail, the storage command output unit 63 outputs a storage command to distribute the multiple trays 30 to at least the same number of automated warehouses 6 as the number of trays used in each production and store them in parallel. The transport control device 10 causes part transport devices 9, the number of which is the same as the number of automated warehouses 6 where storage is performed, to transport parts C in parallel (preferably simultaneously).

[0070] For example, the first line 71d of the production plan data 71 shown in Fig. 10, which is the production plan number "1", indicates that "3" trays of parts with the part name "AAA" will be used. Therefore, the storage command output unit 63 outputs a storage command to distribute "10" trays of delivered parts with the part name "AAA" to "3" or more automated warehouses 6 and store them in parallel.

[0071] Fig. 11 is a diagram showing a schematic diagram of storing part C into the automated warehouse 6 according to the embodiment. In Fig. 11, the storing command output unit 63 distributes "10" trays of delivered parts named "AAA" to the three automated warehouses 6-1, 6-2, and 6-3 and stores them in parallel. The transport control device 10 causes the three part transport devices 9-1, 9-2, and 9-3 to transport "10" trays of parts named "AAA" in parallel.

[0072] The parts conveying device 9-1 conveys trays 30-1, 30-2, and 30-3 of parts with the part name "AAA" from the receiving space 16 to the automated warehouse 6-1. The automated warehouse 6-1 stores the trays 30-1, 30-2, and 30-3 conveyed by the parts conveying device 9-1.

[0073] The parts conveying device 9-2 conveys the trays 30-4, 30-5, and 30-6 of parts with the part name "AAA" from the receiving space 16 to the automated warehouse 6-2. The automated warehouse 6-2 stores the trays 30-4, 30-5, and 30-6 conveyed by the parts conveying device 9-2.

[0074] The parts conveying device 9-3 conveys the trays 30-7, 30-8, 30-9, and 30-10 of parts with the part name "AAA" from the receiving space 16 to the automated warehouse 6-3. The automated warehouse 6-3 stores the trays 30-7, 30-8, 30-9, and 30-10 conveyed by the parts conveying device 9-3.

[0075] 11 shows an example in which the storage command output unit 63 distributes and stores "10" trays of delivered parts named "AAA" into three automated warehouses 6-1, 6-2, and 6-3, but the present disclosure is not limited to this. The storage command output unit 63 may distribute and store "10" trays of delivered parts named "AAA" into four or more automated warehouses 6.

[0076] In addition, it is preferable that the storage command output unit 63 outputs a storage command that causes the number of trays 30 stored in each automated warehouse 6 to be as equal as possible. In other words, since 10÷3=3.33..., it is preferable that the storage command output unit 63 causes each automated warehouse 6 to store "3" trays or "4" trays. For example, when storing "10" trays of parts with the part name "AAA" in three automated warehouses 6, it is preferable that the storage command output unit 63 causes each of two automated warehouses 6 to store "3" trays and one automated warehouse 6 to store "4" trays. However, the present disclosure is not limited to this.

[0077] Similarly, the storage command output unit 63 distributes the "10" trays of parts with the part name "BBB" to the three automated warehouses 6-1, 6-2, and 6-3 and stores them in parallel. The transport control device 10 causes the three part transport devices 9-1, 9-2, and 9-3 to transport the "10" trays of parts with the part name "BBB" in parallel.

[0079] The parts conveying device 9-2 conveys the trays 30-14, 30-15, and 30-16 of parts with the part name "BBB" from the receiving space 16 to the automated warehouse 6-2. The automated warehouse 6-2 stores the trays 30-14, 30-15, and 30-16 conveyed by the parts conveying device 9-2.

[0080] The part conveying device 9-3 conveys the trays 30-17, 30-18, 30-19, and 30-20 of parts with the part name "BBB" from the receiving space 16 to the automated warehouse 6-3. The automated warehouse 6-3 stores the trays 30-17, 30-18, 30-19, and 30-20 conveyed by the part conveying device 9-3.

[0081] Similarly, the storage command output unit 63 distributes the "10" trays of parts with the part name "CCC" to the three automated warehouses 6-1, 6-2, and 6-3 and stores them in parallel. The transport control device 10 causes the three part transport devices 9-1, 9-2, and 9-3 to transport the "10" trays of parts with the part name "CCC" in parallel.

[0082] The parts conveying device 9-1 conveys the trays 30-21, 30-22, and 30-23 of parts with the part name "CCC" from the receiving space 16 to the automated warehouse 6-1. The automated warehouse 6-1 stores the trays 30-21, 30-22, and 30-23 conveyed by the parts conveying device 9-1.

[0083] The parts conveying device 9-2 conveys the trays 30-24, 30-25, and 30-26 containing parts with the part name "CCC" from the receiving space 16 to the automated warehouse 6-2. The automated warehouse 6-2 stores the trays 30-24, 30-25, and 30-26 conveyed by the parts conveying device 9-2.

[0084] The parts conveying device 9-3 conveys the trays 30-27, 30-28, 30-29, and 30-30 of parts with the part name "CCC" from the receiving space 16 to the automated warehouse 6-3. The automated warehouse 6-3 stores the trays 30-27, 30-28, 30-29, and 30-30 conveyed by the parts conveying device 9-3.

[0085] 12 is a diagram showing a schematic diagram of the automated warehouse 6 after part C according to the embodiment has been stored. The automated warehouse 6-1 stores trays 30-1, 30-2, and 30-3 for parts with the part name "AAA." The automated warehouse 6-1 also stores trays 30-11, 30-12, and 30-13 for parts with the part name "BBB." Furthermore, the automated warehouse 6-1 stores trays 30-21, 30-22, and 30-23 for parts with the part name "CCC."

[0086] The automated warehouse 6-2 stores trays 30-4, 30-5, and 30-6 for parts with the part name "AAA." The automated warehouse 6-1 stores trays 30-14, 30-15, and 30-16 for parts with the part name "BBB." The automated warehouse 6-1 also stores trays 30-24, 30-25, and 30-26 for parts with the part name "CCC."

[0087] The automated warehouse 6-3 stores trays 30-7, 30-8, 30-9, and 30-10 for parts with the part name "AAA." The automated warehouse 6-3 also stores trays 30-17, 30-18, 30-19, and 30-20 for parts with the part name "BBB." Furthermore, the automated warehouse 6-1 stores trays 30-27, 30-28, 30-29, and 30-30 for parts with the part name "CCC."

[0088] 9 again, the request command acquisition unit 64 acquires a request command for a component C. The request command is a command requesting a component C to be used in the component mounting system 3. The component C to be used in the component mounting system 3 includes a component C to be mounted on a board P by the mounting apparatus 11.

[0089] In the embodiment, the request command acquisition unit 64 acquires a request command for a part C from the production control device 12. The production control device 12 transmits a request command to the request command acquisition unit 64 when executing a production plan.

[0090] The request command acquisition unit 64 may acquire a request command for the part C from the management control device 4. When executing a production plan in the component mounting system 3, the management control device 4 can output a request command requesting the part C necessary for manufacturing electronic devices to the warehouse control device 8. The request command acquisition unit 64 can acquire the request command for the part C output from the management control device 4.

[0091] Furthermore, the request command acquisition unit 64 may acquire a request command for the component C from the information terminal 5. When executing a production plan in the component mounting system 3, the worker WM can transmit a request command requesting the component C required for manufacturing electronic devices from the information terminal 5 to the warehouse control device 8. The request command acquisition unit 64 can acquire the request command for the component C output from the information terminal 5.

[0092] When the request command is acquired by the request command acquisition unit 64, the retrieval command output unit 65 outputs a retrieval command to the automated warehouses 6, the elevator device 7, and the transport control device 10 to retrieve multiple trays 30 in parallel (preferably simultaneously) from the multiple automated warehouses 6. The transport control device 10 causes part transport devices 9, the number of which is the same as the number of automated warehouses 6 from which retrieval is performed, to transport the trays 30 of parts C in parallel.

[0093] For example, the first line 71d of the production plan data 71 shown in Fig. 10, which is the production plan number "1", indicates that "3" trays will be used for the part named "AAA". Therefore, the outgoing command output unit 65 outputs an outgoing command to in parallel outgo the trays 30-1, 30-4, and 30-7 of the part named "AAA" stored in the automated warehouses 6-1, 6-2, and 6-3, respectively.

[0094] Fig. 13 is a diagram showing the schematic diagram of the retrieval of part C from the automated warehouse 6 according to the embodiment. In the example shown in Fig. 13, the retrieval command output unit 65 causes the tray 30-1 of the part named "AAA" stored in the automated warehouse 6-1 to be retrieval. The transport control device 10 causes the part transport device 9-1 to transport the tray 30-1 of the part named "AAA".

[0095] In addition, the take-out command output unit 65 takes out the tray 30-4 of the part named "AAA" stored in the automated warehouse 6-2. The transport control device 10 causes the part transport device 9-2 to transport the tray 30-4 of the part named "AAA".

[0096] In addition, the take-out command output unit 65 takes out the tray 30-7 of the part named "AAA" stored in the automated warehouse 6-3. The transport control device 10 causes the part transport device 9-3 to transport the tray 30-7 of the part named "AAA".

[0097] The automated warehouse 6-1 delivers the stored tray 30-1 containing the part named "AAA" to the part conveying device 9-1. The part conveying device 9-1 conveys the tray 30-1 delivered from the automated warehouse 6-1 to the production line 25.

[0098] The automated warehouse 6-2 delivers the tray 30-4 containing the part named "AAA" to the part conveying device 9-2. The part conveying device 9-2 conveys the tray 30-4 delivered from the automated warehouse 6-2 to the production line 25.

[0099] The automated warehouse 6-3 delivers the stored tray 30-7 containing the part named "AAA" to the part conveying device 9-3. The part conveying device 9-3 conveys the tray 30-7 delivered from the automated warehouse 6-3 to the production line 25.

[0100] [Comparative Example] FIG. 14 is a diagram showing a schematic diagram of part C being removed from an automated warehouse 6 according to a comparative example. In general, identical parts are stored together in one automated warehouse 6. In the comparative example, automated warehouse 6-1 stores trays 30-1 to 30-10 for a part named "AAA." Automated warehouse 6-2 stores trays 30-11 to 30-20 for a part named "BBB." Automated warehouse 6-3 stores trays 30-21 to 30-30 for a part named "CCC."

[0101] For example, the first line 71d of the production plan data 71 shown in Fig. 10, which has a production plan number "1", indicates that "3" trays will be used for a part named "AAA". In this case, trays 30-1, 30-2, and 30-3 for parts named "AAA" are removed from the automated warehouse 6-1. The removed trays 30-1, 30-2, and 30-3 are transported to the production line 25 by the part transport device 9-1.

[0102] [Comparison between the embodiment and the comparative example] If it takes 20 seconds for each tray to be removed, then in the comparative example shown in FIG. 14, 20 (seconds / tray)×3 (trays)=60 (seconds), so a removal time of 60 seconds is required.

[0103] On the other hand, in the embodiment shown in FIG. 13, the ejection of the trays 30-1, 30-4, and 30-7 is performed in parallel, so that the ejection can be completed in 20 seconds.

[0104] Therefore, the parts management system 2 of the embodiment can reduce the delivery time compared to the comparative example.

[0105] [When the number of parts transport devices is small] Since the parts conveying device 9 is very expensive, there are cases where only a few of them are installed in a factory. For example, there are cases where only two parts conveying devices 9-1 and 9-2 are installed in a factory. In this case, if trays 30-1 to 30-10 containing parts with the part name "AAA" are stored in the three automated warehouses 6-1 to 6-3, there is a possibility that the time required for storing or retrieving the parts will actually be longer.

[0106] Therefore, when the number of part conveying devices 9 is less than the number of trays 30 used in the production plan, it is preferable that the storage command output unit 63 outputs a storage command to distribute the trays 30 to the same number of automated warehouses 6 as the number of part conveying devices 9 and store them in the warehouse.

[0107] For example, the storage command output unit 63 causes trays 30-1 to 30-5 containing parts with the part name "AAA" to be stored in the automated warehouse 6-1. In addition, the storage command output unit 63 causes trays 30-6 to 30-10 containing parts with the part name "AAA" to be stored in the automated warehouse 6-2. The transport control device 10 causes the parts transport device 9-1 to transport trays 30-1 to 30-5 from the receiving space 16 to the automated warehouse 6-1. In addition, the transport control device 10 causes the parts transport device 9-2 to transport trays 30-6 to 30-10 from the receiving space 16 to the automated warehouse 6-2.

[0108] In addition, when the number of part conveying devices 9 is less than the number of trays 30 used in the production plan, it is preferable that the outgoing command output unit 65 outputs an outgoing command to in parallel outgo the trays 30 to the same number of automated warehouses 6 as the number of part conveying devices 9.

[0109] For example, the outgoing command output unit 65 outgoes trays 30-1 and 30-2 containing parts with the part name "AAA" to the automated warehouse 6-1. In addition, the outgoing command output unit 65 outgoes tray 30-6 containing parts with the part name "AAA" to the automated warehouse 6-2. The transport control device 10 causes the parts transport device 9-1 to transport the trays 30-1 and 30-2 outgoing from the automated warehouse 6-1 from the automated warehouse 6-1 to the production line 25. In addition, the transport control device 10 causes the parts transport device 9-2 to transport tray 30-6 outgoing from the automated warehouse 6-2 from the automated warehouse 6-2 to the production line 25.

[0110] As a result, the parts management system 2 of the embodiment can reduce the possibility that the time required for entering or leaving the warehouse will actually be longer.

[0111] [Inventory Processing] FIG. 15 is a flowchart showing the warehousing process according to the embodiment.

[0112] The tape reels 23 are delivered from a parts supplier. A worker WM in the receiving space 16 places the tape reel 23 holding the part C on the tray 30. The worker WM uses an information terminal 26 to read the identifiers 24 of each of the multiple tape reels 23. The information terminal 26 transmits the identification information of the identifiers 24 to the identification information acquisition unit 62 of the warehouse control device 8. The identification information acquisition unit 62 acquires the identification information (step S100).

[0113] The storage command output unit 63 determines whether the number of part conveying devices 9 is less than the number of trays 30 used in the production plan (step S102). If the storage command output unit 63 determines that the number of part conveying devices 9 is not less than the number of trays 30 used in the production plan (No in step S102), the process proceeds to step S104. If the storage command output unit 63 determines that the number of part conveying devices 9 is less than the number of trays 30 used in the production plan (Yes in step S102), the process proceeds to step S106.

[0114] If the storage command output unit 63 determines that the number of part conveying devices 9 is not less than the number of trays 30 used in the production plan (No in step S102), it outputs a storage command to distribute and store the trays 30 in at least the same number of automated warehouses 6 as the number of trays 30 used in the production plan (step S104), and terminates the processing.

[0115] If the storage command output unit 63 determines that the number of part conveying devices 9 is less than the number of trays 30 used in the production plan (Yes in step S102), it outputs a storage command to distribute and store the trays 30 in the same number of automated warehouses 6 as the number of part conveying devices 9 (step S106), and terminates the processing.

[0116] [Outbound Processing] FIG. 16 is a flowchart showing the shipping process according to the embodiment.

[0117] When a production plan is executed in the component mounting system 3, the production control device 12 transmits a request command to the request command acquisition unit 64. The request command acquisition unit 64 acquires a request command for the component C from the production control device 12 (step S200).

[0118] The out-of-stock command output unit 65 determines whether the number of part conveying devices 9 is less than the number of trays 30 used in the production plan (step S202). If the out-of-stock command output unit 65 determines that the number of part conveying devices 9 is not less than the number of trays 30 used in the production plan (No in step S202), the process proceeds to step S204. If the out-of-stock command output unit 65 determines that the number of part conveying devices 9 is less than the number of trays 30 used in the production plan (Yes in step S202), the process proceeds to step S206.

[0119] If the out-of-stock command output unit 65 determines that the number of part conveying devices 9 is not less than the number of trays 30 used in the production plan (No in step S202), it outputs an out-of-stock command to instruct trays 30 to be shipped in parallel from the same number of automated warehouses 6 as the number of trays 30 used in the production plan (step S204), and terminates the processing.

[0120] If the out-of-stock command output unit 65 determines that the number of part conveying devices 9 is less than the number of trays 30 used in the production plan (Yes in step S202), it outputs an out-of-stock command to instruct the trays 30 to be out-stocked in parallel from the same number of automated warehouses 6 as the number of part conveying devices 9 (step S206), and terminates the processing.

[0121] [Computer System] FIG. 17 is a block diagram showing an example of a computer system 1000 according to an embodiment. Each of the above-mentioned management control device 4, warehouse control device 8, transport control device 10, production control device 12, and information terminals 5 and 26 includes a computer system 1000. The computer system 1000 has a processor 1001 such as a CPU (Central Processing Unit), a main memory 1002 including a non-volatile memory such as a ROM (Read Only Memory) and a volatile memory such as a RAM (Random Access Memory), a storage 1003, and an interface 1004 including an input / output circuit. Each of the functions of the management control device 4, the functions of the warehouse control device 8, the functions of the transport control device 10, the functions of the production control device 12, and the functions of the information terminals 5 and 26 are stored in the storage 1003 as a computer program. The processor 1001 reads the computer program from the storage 1003, expands it in the main memory 1002, and executes the above-mentioned processing according to the computer program. Note that the computer program may be distributed to the computer system 1000 via a network.

[0122] The computer program can execute, in accordance with the above-described embodiment, the following: acquiring identification information of part C; and, based on the identification information and production plan data, outputting a storage command to distribute and store multiple parts C in multiple automated warehouses 6.

[0123] The computer program can also output a storage command to distribute and store multiple trays 30 into at least as many automated warehouses 6 as the number of trays 30 used in the production plan, and when the production plan is executed, output an out-of-stock command to unload the multiple trays 30 in parallel from the multiple automated warehouses 6.

[0124] The computer program can also execute, when a production plan is executed, outputting an out-of-stock command to cause multiple trays 30 to be out-stocked in parallel from the same number of automated warehouses 6 as the number of trays 30 used in the production plan.

[0125] In addition, the computer program can execute the following: when the number of part conveying devices 9 is less than the number of trays 30 used in the production plan, outputting a storage command to distribute and store multiple trays 30 in the same number of automated warehouses 6 as the number of part conveying devices 9.

[0126] In addition, the computer program can execute the following: when the number of part conveying devices 9 is less than the number of trays 30 used in the production plan, outputting an out-of-stock command to cause multiple trays 30 to be out-stocked in parallel from an automated warehouse 6 in a number equal to the number of part conveying devices 9.

[0127] [effect] As described above, according to the embodiment, the warehouse control device 8 can distribute and store multiple parts C to multiple automated warehouses 6 based on the identification information and production plan data 71. Therefore, the multiple automated warehouses 6 can retrieve parts C in parallel when retrieving them from the warehouse. This allows the parts management system 2 to reduce the time required for retrieving parts C.

[0128] The storage command output unit 63 can distribute and store the multiple trays 30 into at least the same number of automated warehouses 6 as the number of trays 30 used in the production plan. Therefore, the multiple automated warehouses 6 can retrieve the number of trays 30 used in the production plan in the time it takes to retrieve one tray 30. This allows the parts management system 2 to reduce the time required to retrieve parts C.

[0129] When the number of part conveying devices 9 is less than the number of trays 30 used in the production plan, the storage command output unit 63 can store the multiple trays 30 in a distributed manner among the same number of automated warehouses 6 as the number of part conveying devices 9. This enables the part management system 2 to reduce the possibility that the storage or removal time will actually be longer. [Explanation of symbols]
