The distribution table file indicates the type of the component C to be transferred from the automatic warehouse 6 to the plurality of mounting devices 11, respectively. The distribution table file may contain not only the types of the components C but also the number of the components C allocated to each of the plurality of mounting devices 11.

In the present embodiment, the distribution table file indicates the reels 23 allocated to the plurality of mounting devices 11, respectively. A plurality of tape feeders 117 are provided in one mounting apparatus 11. The distribution table file indicates reels 23 allocated to the plurality of tape feeders 117, respectively.

The distribution table file is determined based on the specifications of the mounting device 11 or the component supply device 112. In addition, the distribution table file may also be determined based on the electronic device to be manufactured. The distribution table file is registered in the management control device 4 before the electronic device is manufactured. The delivery table file obtaining unit 61 obtains a delivery table file registered in the management control device 4.

The work order obtaining unit 62 obtains a work order indicating a product of the number of boards P on which the components C are mounted and the number of components C mounted on the boards P from the management control device 4.

Fig. 12 is a schematic diagram for explaining a work order of the present embodiment. In the manufacture of electronic devices, the substrate P is sequentially conveyed to the plurality of mounting devices 11. The plurality of mounting devices 11 mount the components C on the conveyed substrates P, respectively. The component C is mounted on the substrate P by the plurality of mounting devices 11, thereby manufacturing the electronic apparatus. In the example shown in fig. 12, the first mounting device 11 mounts the component C in the first region Pa of the substrate P, the second mounting device 11 mounts the component C in the second region Pb of the substrate P, the third mounting device 11 mounts the component C in the third region Pc of the substrate P, and the fourth mounting device 11 mounts the component C in the fourth region Pd of the substrate P.

The kind and the number of the components C mounted to the substrate P are determined based on the electronic apparatus to be manufactured. Further, the number of substrates P on which the components C are mounted is determined based on the number of electronic devices to be manufactured. The work order represents a part C determined based on the number of electronic devices to be manufactured. The work order indicates the kind and the number of parts C that should be transferred from the automated warehouse 6 to the plurality of mounting devices 11, respectively. The work order is determined based on the electronic device to be manufactured. The work order is registered in the management control device 4 before the electronic device is manufactured. The work order obtaining unit 62 obtains a work order registered in the management control device 4.

The component-use-up data acquisition unit 63 acquires component-use-up data indicating that the component C of the reel 23 is consumed from the information terminal 5. The plurality of reels 23 are mounted to the plurality of tape feeders 117, respectively. In the mounting device 11, a plurality of components C of the reel 23 are consumed in sequence. The operator WM of the mounting device 11 can recognize whether all the components C held by the reel 23 are consumed. For example, when all of the components C held by the reel 23 are consumed, the production control device 12 operates a warning device provided to the mounting device 11. The warning device may be a warning light or an audio output device. The operator WM can recognize that all the components C held on the reel 23 are consumed based on the warning device. The operator WM can visually recognize that all of the components C held on the reel 23 are consumed. When recognizing that all the components C held by the reel 23 are consumed, the operator WM operates the information terminal 5 and sends component-use-up data indicating that all the components C of the reel 23 are consumed to the warehouse control device 8. The component-use-up data acquiring unit 63 acquires component-use-up data transmitted from the information terminal 5.

The component-end data contains identification data of the reels 23 in which the components C are all consumed. A uniform identifier 25 is assigned to the reel 23. When the uniform identifier 25 includes a barcode and the information terminal 5 has a function of a barcode reader, the operator WM reads the uniform identifier 25 assigned to the reel 23 where the component C is entirely consumed, using the information terminal 5. Thereby, the reels 23 and the components C that are all consumed are determined. The component-use-up data acquiring unit 63 can identify the reels 23 in which all the components C are consumed and all the components C that are consumed, based on the component-use-up data transmitted from the information terminal 5.

The warehouse command unit 64 outputs a warehouse command of the reels 23 to the automatic warehouse 6 and the elevator apparatus 7. The warehouse entry command unit 64 outputs a warehouse entry command for causing the reels 23, which are delivered from the component suppliers and assigned with the uniform identifier 25, to be warehoused in the automated warehouse 6.

The delivery instruction unit 65 outputs a delivery instruction of the reel 23 to the automated warehouse 6 and the elevator apparatus 7. The delivery instruction unit 65 outputs a delivery instruction for delivering the reels 23, to which the uniform identifier 25 is assigned and which are stored in the automated warehouse 6, from the automated warehouse 6.

The delivery instruction unit 65 outputs a delivery instruction for the reel 23 based on the delivery table file. The components C suitable for the mounting device 11 are taken out of the warehouse by taking out the reels 23 from the automated warehouse 6 based on the distribution table file. By discharging the component C suitable for the mounting device 11, the component C suitable for the manufacture of the electronic apparatus can be efficiently discharged.

The delivery instruction unit 65 outputs a delivery instruction based on the delivery table file and the selection instruction of the work order. The selection instruction is output from the information terminal 5. The operator WM can select, for example, the shipment of the component C based on the delivery table file and the shipment of the component C based on the work order based on the manufacturing condition of the electronic device. The operator WM operates the information terminal 5, and sends a selection instruction of the delivery of the component C based on the delivery table file and the delivery of the component C based on the work order to the warehouse control device 8. The delivery instruction unit 65 acquires a selection instruction transmitted from the information terminal 5. The delivery instruction unit 65 outputs a delivery instruction based on a selection instruction by the operator WM. Thus, the component C suitable for manufacturing the electronic device can be efficiently delivered based on the selection of the operator WM.

The shipment instruction unit 65 outputs a shipment instruction based on the component-end data. When all the components C of a specific reel 23 among the reels 23 mounted on the plurality of tape feeders 117 are consumed, the operator WM operates the information terminal 5 and transmits component-use data indicating that all the components C of the specific reel 23 are consumed to the warehouse control device 8. The delivery instruction unit 65 acquires the component-use data transmitted from the information terminal 5. As described above, the component-end data contains the reel 23 that determines that the component C is entirely consumed and the identification data of the entirely consumed component C. The payout command unit 65 outputs a payout command to payout the reel 23 holding the same type of component C as the all of the consumed components C held on the specific reel 23.

The inventory management unit 66 manages the inventory of the components C stored in the automatic warehouse 6. The inventory management unit 66 acquires inventory data of the components C stored in the automatic warehouse 6. The inventory management unit 66 stores the acquired inventory data. The stock data includes identification data of the component C stored in the automated warehouse 6. The identification data of the component C contains identification data of the uniform identifier 25 given to the reel 23. The inventory data of the parts C includes the types (names) and the numbers of the parts C stored in the automatic warehouse 6. The types of the components C include those held by the plurality of reels 23. The number of components C includes the number of components C held by the plurality of reels 23, respectively.

The stock data output unit 67 outputs stock data of the same type of component C as the component C of the reel 23 that is consumed in the whole mounting apparatus 11 to the information terminal 5 based on the component-end data. For example, when all of the components C of the predetermined type held by the reels 23 are consumed in the mounting apparatus 11 and a plurality of reels 23 holding components C of the same type as the components C of the predetermined type are stocked in the automatic warehouse 6, the stock data output unit 67 transmits stock data indicating that the reels 23 holding components C of the same type as the components C of the predetermined type are stocked in the automatic warehouse 6 to the information terminal 5.

The information terminal 5 causes a display device of the information terminal 5 to display inventory data. In the present embodiment, the stock data displayed on the display device of the information terminal 5 includes list data indicating the time of storage of the plurality of reels 23.

Fig. 13 is a diagram schematically showing a display device of the information terminal 5 according to the present embodiment. When a plurality of reels 23 holding the same type of component C as the first component of the predetermined type of component C are stored in the automatic warehouse 6, inventory data indicating the plurality of reels 23 holding the same type of component C are displayed on the display device of the information terminal 5. As shown in fig. 13, list data indicating the serial numbers of reels 23 stocked in the automatic warehouse 6 and the time of stocking indicating the time of stocking the reels 23 in the automatic warehouse 6 is displayed on the display device of the information terminal 5.

The operator WM can select a reel 23 to be stocked from among a plurality of reels 23 stocked in the automatic warehouse 6 by operating the information terminal 5. The operator WM operates the information terminal 5 and transmits request data for discharging the selected reel 23 from the automatic warehouse 6 to the warehouse control device 8. The operator WM operates the information terminal 5, and for example, transmits request data for requesting the shipment of the reel 23 having the longest elapsed time from the time of shipment to the warehouse control device 8.

The delivery instruction unit 65 outputs a delivery instruction for delivering the reels 23 holding the component C selected from the stock data by the operator WM. The delivery instruction unit 65 outputs, for example, a delivery instruction for delivering the reel 23 having the longest elapsed time from the time of delivery to the information terminal 5, based on the request data.

The count value acquisition unit 68 acquires the count value of the component C of the reel 23 output from the information terminal 5. The operator WM counts the number of components C held by the reel 23 in the mounting device 11. The operator WM operates the information terminal 5 and sends a count value indicating the number of components C held by the reel 23 to the warehouse control device 8. The count value acquisition unit 68 acquires the count value of the component C of the reel 23 transmitted from the information terminal 5.

The counting unit 69 obtains a count value of the component C of the reel 23 output from the production control device 12 that controls the mounting device 11. The production control device 12 counts the number of components C carried out from the reel 23 and mounted on the substrate P based on the operation of the suction nozzle 113 and the operation of the mounting head 114. The production control device 12 outputs a count value indicating the number of components C held by the reel 23 to the counting section 69. The counting unit 69 obtains the count value of the component C of the reel 23 sent from the production control device 12. The stock management unit 66 stores the count value of the component C of the reel 23 acquired by the counting unit 69.

When it is determined that all the components C of the reel 23 are consumed based on the count value of the components C of the reel 23 output from the information terminal 5 and acquired by the count value acquisition unit 68, the zero processing unit 70 outputs a zero processing instruction to change the count value of the components C of the reel 23 stored in the inventory management unit 66 to zero.

The count value of the components C of the reel 23 obtained by the counting unit 69 may be different from the number of components C actually held by the reel 23. As described above, the count value of the component C of the reel 23 acquired by the counting section 69 is calculated based on the operation of the suction nozzle 113 and the operation of the mounting head 114. For example, the count value of the components C obtained by the counting unit 69 may be different from the number of components C actually held by the reel 23 due to some cause such as an error in mounting the components C by the mounting head 114. When the count value of the components C obtained by the counting unit 69 is different from the number of components C actually held by the reel 23, the inventory management unit 66 stores an erroneous count value.

Therefore, even if the count value of the component C of the reel 23 stored in the stock management unit 66 is 1 or more, the zero processing unit 70 outputs a zero processing instruction to zero the count value of the component C of the reel 23 stored in the stock management unit 66 when it is determined that all the components C of the reel 23 are consumed based on the count value of the component C of the reel 23 output from the information terminal 5 and acquired by the count value acquisition unit 68. The count value of the components C transmitted from the information terminal 5 is the number of components C actually counted by the operator WM, and is a correct value. The inventory management unit 66 can store a correct count value by correcting the count value of the component C of the reel 23 stored in the inventory management unit 66 based on the count value of the component C transmitted from the information terminal 5.

Even if the count value of the component C of the reel 23 stored in the stock management unit 66 is zero, the zero processing unit 70 can output a zero release instruction to change the count value of the component C of the reel 23 stored in the stock management unit 66 to the remaining value when it is determined that the component C remains in the reel 23 based on the count value of the component C of the reel 23 output from the information terminal 5.

The discard command unit 71 outputs a discard command of the reel 23, which is set to zero in the count value of the component C by the zero processing unit 70, to the stock management unit 66 and the information terminal 5. The stock management unit 66 deletes the stock data of the reel 23 whose count value of the component C is zero based on the discard instruction. The display device of the information terminal 5 displays display data of the reel 23 for setting the count value of the operator WM disposing member C to zero based on the discard instruction.

The format storage unit 72 stores the format of the individual identifier 24 assigned to each reel 23.

Fig. 14 is a diagram schematically showing the individual identifier 24 of the present embodiment. The identification data of the individual identifier 24 includes the type (name) of the component C held in the reel 23, the serial number of the component C, and the number of the components C.

Fig. 14A shows the individual identifier 24 of the reel 23 delivered from the first component supplier. Fig. 14B shows the individual identifier 24 of the reel 23 delivered from the second component supplier. In the individual identifier 24 shown in fig. 14A, the first part 24A indicates the kind of the component C, the second part 24B indicates the serial number of the component C, and the third part 24C indicates the number of the components C. In the individual identifier 24 shown in fig. 14B, a fourth portion 24D represents the serial number of the component C, a fifth portion 24E represents the number of the components C, and a sixth portion 24F represents the kind of the component C.

As shown in fig. 14A and 14B, the format of the individual identifier 24 of the reel 23 delivered from the first component supplier is different from the format of the individual identifier 24 of the reel 23 delivered from the second component supplier.

The individual identifier 24 is in a variety of formats. The format storage 72 stores, for example, the format of the individual identifier 24 for each of the plurality of component suppliers.

The identification data acquisition unit 73 acquires, from the reading device 33, identification data of the individual identifier 24 read by the reading device 33 during the warehouse entry of the reel 23. The reading means 33 read the individual identifier 24 with reference to the format of the individual identifier 24. Even if reels 23 having individual identifiers 24 of different formats are sequentially carried into the elevator apparatus 7, the reading apparatus 33 can read the individual identifiers 24 by referring to the format of the individual identifiers 24, respectively.

The uniform identifier output unit 74 generates identification data of the uniform identifier 25 assigned to each of the plurality of reels 23 based on the format of the individual identifier 24 stored in the format storage unit 72 and the identification data of the individual identifier 24 acquired by the identification data acquisition unit 73. The unified identifier output unit 74 unifies the formats of the plurality of individual identifiers 24 based on the formats of the individual identifiers 24 and the identification data of the individual identifiers 24, and generates the unified identifier 25 in the unified format. The unified identifier output unit 74 outputs the generated identification data of the unified identifier 25 to the assigning device 35.

In the present embodiment, the identification data of the universal identifier 25 includes at least one of the type of the component C held in the reel 23, the serial number of the component C, and the number of the components C. The identification data of the universal identifier 25 may include only the type of the component C, or may include only the serial number of the component C. The identification data of the uniform identifier 25 may include at least two of the type of the component C, the serial number of the component C, and the number of the components C. In the present embodiment, the identification data of the uniform identifier 25 includes the type of the component C and the serial number of the component C, and does not include the number of the components C. Since the plurality of formats are unified into one format, the component C held on the reel 23 can be specified based on the unified identifier 25 even if the amount of information included in the identification data is small.

The component data registration unit 75 stores component data indicating the unique value of the component C stocked in the automatic warehouse 6. The component data is registered in the component data registration unit 75 in advance before the component C is put into the automated warehouse 6.

Fig. 15 is a diagram showing component data of the present embodiment. As shown in fig. 15, in the present embodiment, the component data includes the type (name) of the components C held by the reel 23, the number of the components C, and the size of the components C. The dimensions of the component C include the dimensions in the X-axis direction, the dimensions in the Y-axis direction, and the dimensions in the Z-axis direction. The component data may include the shape of the component C held by the reel 23.

The uniform identifier output unit 74 can output the identification data of the uniform identifier 25 based on the detection data of the detection device 34 and the component data registered in the component data registration unit 75. For example, it is possible to deliver the reel 23 to which the individual identifier 24 is not assigned from the component supplier. Even if the individual identifier 24 is not given to the reel 23, the unified identifier output section 74 can determine the component C held by the reel 23 based on the detection data of the detection device 34 and the component data registered in the component data registration section 75. The detecting device 34 is capable of detecting the number of the components C and the size of the components C. The component data registered in the component data registration section 75 includes the type (name) of the component C, the number of the components C, and the size of the component C. Therefore, the uniform identifier output unit 74 can identify the type of the component C held on the reel 23 by collating the detection data of the detection device 34 with the component data registered in the component data registration unit 75. By specifying the type of the component C held by the reel 23, the uniform identifier output unit 74 can output the identification data of the uniform identifier 25.

The determination unit 76 compares the detection data of the detection device 34, the component data registered in the data registration unit 75, and the identification data of the uniform identifier 25 given to the reel 23, and determines whether or not the uniform identifier 25 is correct. For example, the uniform identifier 25 that should be assigned to the first reel 23 may be erroneously assigned to the second reel 23. After the uniform identifier 25 is given to the reel 23 by the giving device 35, when a confirmation process for determining whether or not the uniform identifier 25 given to the reel 23 is correct is performed, the determining unit 76 can determine whether or not the uniform identifier 25 is correct by collating the detection data of the detecting device 34, the component data registered in the component data registering unit 75, and the identification data of the uniform identifier 25 given to the reel 23.

The notification unit 77 outputs an operation instruction to the notification device 38 based on the determination data of the determination unit 76. The notification device 38 may be, for example, a warning lamp provided in the elevator apparatus 7 or an audio output device. When the determination unit 76 determines that the error uniform identifier 25 is given to the reel 23, the notification unit 77 outputs an operation instruction to the notification device 38 based on the determination data of the determination unit 76. By the operation of the notification device 38, the operator WM can recognize the uniform identifier 25 to which the error is given to the reel 23.

Warehousing (in the case of having an individual identifier)

Fig. 16 is a flowchart showing the warehouse entry processing according to the present embodiment. Fig. 16 shows the warehouse entry processing when the individual identifier 24 is given to the reel 23. The reels 23 delivered from the parts suppliers are carried into the elevator apparatus 7 by the parts transporting apparatus 9. The reading device 33 reads the individual identifier 24 in the elevator device 7. The identification data acquisition unit 73 acquires the identification data of the individual identifier 24 read by the reading device 33 (step SA 1).

The identification data of the individual identifier 24 includes the kind (name) of the component C held in the reel 23, the serial number of the component C held in the reel 23, and the number of the components C held in the reel 23. The type, serial number, and number of the components C acquired by the identification data acquisition unit 73 are stored in the inventory management unit 66 (step SA 2).

The unified identifier output unit 74 generates the identification data of the unified identifier 25 based on the format of the individual identifier 24 stored in the format storage unit 72 and the identification data of the individual identifier 24 acquired by the identification data acquisition unit 73. The unified identifier output unit 74 outputs the generated identification data of the unified identifier 25 to the assigning device 35 (step SA 3).

The uniform identifier output unit 74 outputs an operation command for operating the applying device 35. The assigning means 35 assigns the reel 23 with the uniform identifier 25. After the reel 23 is given the uniform identifier 25, the warehouse-in command unit 64 outputs a warehouse-in command for warehousing the reel 23 to the automated warehouse 6 (step SA 4).

The plurality of reels 23 to which the uniform identifier 25 is assigned are stored in the automated warehouse 6.

Warehousing (without individual identifier)

Fig. 17 is a flowchart showing the warehouse entry processing according to the present embodiment. Fig. 17 shows the warehouse entry processing when the individual identifier 24 is not given to the reel 23. The reels 23 delivered from the parts suppliers are carried into the elevator apparatus 7 by the parts transporting apparatus 9. The detecting device 34 detects the component C held by the reel 23 in the elevator apparatus 7. The unified identifier output unit 74 acquires the detection data of the detection device 34 (step SB 1).

The unified identifier output unit 74 determines whether or not the component C carried into the elevator apparatus 7 is the component C registered in the component data registration unit 75 based on the detection data of the detection device 34 and the component data registered in the component data registration unit 75 (step SB 2).

The detection data of the detection device 34 contains the size and the number of the components C. The component data registered in the component data registration section 75 includes the size and the number of the components C. Therefore, the unified identifier output unit 74 can determine whether or not the component C loaded into the elevator apparatus 7 is the component C registered in the component data registration unit 75 by collating the detection data of the detection device 34 with the component data registered in the component data registration unit 75.

In step SB2, when it is determined that the component C loaded into the elevator apparatus 7 is the component C registered in the component data registration unit 75 (step SB2: yes), the unified identifier output unit 74 generates the identification data of the unified identifier 25 and outputs the identification data to the assigning apparatus 35 (step SB 3).

The uniform identifier output unit 74 outputs an operation command for operating the applying device 35. The assigning means 35 assigns the reel 23 with the uniform identifier 25. After the reel 23 is given the uniform identifier 25, the warehouse-in command unit 64 outputs a warehouse-in command for warehousing the reel 23 to the automated warehouse 6 (step SB 4).

In step SB2, when it is determined that the component C loaded into the elevator apparatus 7 is not the component C registered in the component data registration unit 75 (step SB2: NO), the warehouse-in processing is completed. The reel 23 is carried out of the elevator apparatus 7.

[ confirmation Process ]

Fig. 18 is a flowchart showing the confirmation processing of the present embodiment. The confirmation processing is processing for determining whether or not the uniform identifier 25 given to the reel 23 is correct.

In the elevator apparatus 7, the reel 23 is given a uniform identifier 25 by a giving device 35. After the reel 23 is given the uniform identifier 25, the reader 33 reads the uniform identifier 25 in the elevator apparatus 7 before the reel 23 is put in the automated warehouse 6. The determination unit 76 acquires the identification data of the uniform identifier 25 read by the reading device 33 (step SC 1).

Before the reels 23 are stocked in the automatic warehouse 6, the detecting device 34 detects the components C held on the reels 23 in the elevator apparatus 7. The determination unit 76 acquires detection data of the detection device 34 (step SC 2).

The determination unit 76 collates the detection data of the detection device 34, the component data registered in the component data registration unit 75, and the identification data of the unique identifier 25 (step SC 3).

The determination unit 76 determines whether the universal identifier 25 is correct or not by comparing the detection data, the component data, and the identification data (step SC 4).

The identification data of the individual identifier 24 before conversion into the unified identifier 25 includes the kind of the component C, the serial number of the component C, and the number of the components C. The identification data of the uniform identifier 25 contains the type of the component C and the serial number of the component C. The detection data of the detection device 34 contains the number of the components C and the size of the components C. The component data includes the type of the component C, the serial number of the component C, and the number of the components C. The determination unit 76 can determine the type of the component C held by the reel 23 by collating the detection data of the detection device 34 with the component data. The determination unit 76 can determine whether or not the uniform identifier 25 is properly assigned to the reel 23 to be assigned by comparing the type of the component C determined by the comparison of the detection data of the detection device 34 and the component data with the type of the component C included in the identification data of the uniform identifier 25.

If it is determined in step SC4 that the uniform identifier 25 is properly assigned to the reel 23 (yes in step SC 4), the warehouse-in command unit 64 outputs a warehouse-in command for warehousing the reel 23 to the automatic warehouse 6 (step SC 5).

If it is determined in step SC4 that the uniform identifier 25 is not properly assigned to the reel 23 (step SC4: no), the notification unit 77 outputs an operation instruction to the notification device 38 (step SC 6).

By the operation of the notification device 38, the operator WM can recognize that the wrong uniform identifier 25 is given to the reel 23.

The selection shipment process refers to a process of bringing reels 23 out of the automated warehouse 6 based on a shipment table file shipment and a selection instruction of shipment based on a work order.

The delivery instruction unit 65 acquires the delivery table file and the work order selection instruction transmitted from the information terminal 5 (step SE 1).

The delivery instruction unit 65 determines whether or not the delivery table file is selected based on the selection instruction (step SE 2).

In step SE2, when it is determined that the delivery table file is selected (step SE2: yes), the delivery table file obtaining unit 61 obtains the delivery table file from the management control device 4 (step SE 3).

The delivery instruction unit 65 outputs a delivery instruction based on the delivery table file acquired by the delivery table file acquisition unit 61 (step SE 4).

In step SE2, when it is determined that the work order is selected (step SE2: NO), the work order obtaining unit 62 obtains the work order from the management control device 4 (step SE 5).

The shipment instruction unit 65 outputs a shipment instruction based on the work order acquired by the work order acquisition unit 62 (step SE 4).

[ parts use-up ex-warehouse Process ]

Fig. 21 is a flowchart showing the component-use-up shipment process according to the present embodiment. The component-depleted shipment process refers to a process of bringing out reels 23 from the automated warehouse 6 when all of the components C of a particular reel 23 in the mounting device 11 are consumed.

The component-use-up data acquiring unit 63 acquires component-use-up data indicating that the component C of the reel 23 is consumed from the information terminal 5 (step SF 1).

The stock management unit 66 determines whether or not the reels 23 holding the same type of components C as those of the reels 23 consumed in the entire mounting apparatus 11 are stocked (step SF 2).

In step SF2, when it is determined that a plurality of reels 23 holding components C of the same type are stocked (step SF2: yes), the stock data output unit 67 outputs stock data of components C of the same type as those of the reels 23 consumed in the whole mounting apparatus 11 to the information terminal 5 based on the component-end data (step SF 3).

As described with reference to fig. 13, when the inventory data is output to the information terminal 5, the inventory data is displayed on the display device of the information terminal 5. The display device of the information terminal 5 displays, as inventory data, inventory data indicating serial numbers of reels 23 stocked in the automatic warehouse 6 and a warehouse-in time indicating a time when the reels 23 are stocked in the automatic warehouse 6.

The operator WM operates the information terminal 5 to select a reel 23 to be stocked from among a plurality of reels 23 stocked in the automatic warehouse 6. The operator WM operates the information terminal 5, and transmits request data for requesting the shipment of the reel 23 having the longest elapsed time from the time of shipment to the warehouse control device 8, for example.

The delivery instruction unit 65 acquires the request data transmitted from the information terminal 5 (step SF 4).

The delivery instruction unit 65 outputs a delivery instruction for delivering the reel 23 having the longest elapsed time from the time of delivery, for example, based on the request data transmitted from the information terminal 5 (step SF 5).

By taking out the reel 23 having the longest elapsed time from the time of storage, the old reel 23 can be kept from being stored in the automatic warehouse 6.

[ zero treatment ]

Fig. 22 is a flowchart showing zero processing in the present embodiment. The zero processing is processing for changing the count value of the component C of the reel 23 stored in the stock management unit 66 to zero.

The counting unit 69 obtains the count value of the component C of the reel 23 output from the mounting device 11 (step SG 1).

The count value of the component C of the reel 23 output from the mounting device 11 is registered in the stock management section 66. The stock management unit 66 stores the count value of the component C of the reel 23 acquired by the counting unit 69 (step SG 2).

The count value acquisition unit 68 acquires the count value of the component C of the reel 23 output from the information terminal 5 (step SG 3).

The zero processing unit 70 determines whether all the components C of the reel 23 are consumed based on the count value of the components C of the reel 23 acquired by the count value acquisition unit 68 (step SG 4).

In step SG4, when it is determined that all parts C of the reels 23 are consumed (step SG4: yes), the zero processing unit 70 outputs a zero processing instruction to change the count value of the parts C of the reels 23 stored in the stock management unit 66 to zero (step SG 5).

The discard command unit 71 outputs the discard command of the reel 23, which is set to zero by the zero processing unit 70, to the stock management unit 66 and the information terminal 5 (step SG 6).

The stock management unit 66 deletes the stock data of the reel 23 whose count value of the component C is zero based on the discard instruction. The display device of the information terminal 5 displays display data of the reel 23 for setting the count value of the operator WM disposing member C to zero based on the discard instruction.

In step SG4, when it is determined that all of the components C of the reel 23 have not been consumed (step SG4: NO), the zero-processing unit 70 does not output a zero-processing command, and the zero-processing is completed.

Even if the actual count value of the component C is zero and the count value stored in the stock management unit 66 is 1 or more, the stock management unit 66 can store the correct count value by performing zero processing.

[ zero release treatment ]

Fig. 23 is a flowchart showing the zero release processing according to the present embodiment. The zero release process is a process of changing the count value of the component C of the reel 23 stored in the stock management unit 66 to an actual remaining value.

The counting unit 69 obtains the count value of the component C of the reel 23 output from the mounting device 11 (step SH 1).

The count value of the component C of the reel 23 output from the mounting device 11 is registered in the stock management section 66. The stock management unit 66 stores the count value of the component C of the reel 23 acquired by the counting unit 69 (step SH 2).

The count value acquisition unit 68 acquires the count value of the component C of the reel 23 output from the information terminal 5 (step SH 3).

The zero processing unit 70 determines whether or not the component C remains on the reel 23 based on the count value of the component C of the reel 23 acquired by the count value acquisition unit 68 (step SH 4).

In step SH4, when it is determined that all the components C of the reels 23 are consumed (step SH4: yes), the zero processing unit 70 outputs a zero release instruction for changing the count value of the components C of the reels 23 stored in the inventory management unit 66 to an actual remaining value (step SH 5).

The remaining number refers to the number of components C remaining on the reel 23. The count value of the component C transmitted from the information terminal 5 indicates the actual remaining value. The remaining number of components C transmitted from the information terminal 5 is the number of components C actually counted by the operator WM, and is a correct value. The inventory management unit 66 can store a correct count value by correcting the count value of the component C stored in the reel 23 of the inventory management unit 66 based on the remaining number of components C transmitted from the information terminal 5.

The discard command unit 71 outputs a recovery command of the reel 23, which is changed from the count value of the component C to the remaining value by the zero processing unit 70, to the stock management unit 66 and the information terminal 5 (step SH 6).

The inventory management part 66 restores the inventory data of the deleted reel 23 based on the restoration instruction. The display device of the information terminal 5 displays display data for restoring the reel 23 having the remaining number of the component C of 1 or more to the mounting device 11 based on the restoration instruction.

In step SH4, when it is determined that the component C of the reel 23 is not left (step SH4: NO), the zero release instruction is not output from the zero processing unit 70, and the zero release processing is completed.

Even if the count value (remaining number) of the actual component C is 1 or more and the count value stored in the stock management unit 66 is zero, the stock management unit 66 can store the correct count value by performing the zero-release processing.

[ computer System ]

Fig. 24 is a block diagram showing an example of the computer system 1000. The management control device 4, the warehouse control device 8, the conveyance control device 10, the production control device 12, and the information terminal 5 described above each include a computer system 1000. The computer system 1000 has: a processor 1001 such as a CPU (Central Processing Unit central processing unit); main Memory 1002 including a nonvolatile Memory such as a ROM (Read Only Memory) and a volatile Memory such as a RAM (Random Access Memory random access Memory); a memory 1003; and an interface 1004 including input-output circuitry. The functions of the management control device 4, the functions of the warehouse control device 8, the functions of the conveyance control device 10, the functions of the production control device 12, and the functions of the information terminal 5 are stored in the memory 1003 as computer programs, respectively. The processor 1001 reads out a computer program from the memory 1003, expands the computer program in the main memory 1002, and executes the above processing according to the computer program. In addition, the computer program may also be distributed to the computer system 1000 via a network.

The computer program can be executed according to the above embodiment: based on the format of the individual identifier 24 assigned to each of the plurality of components C and the identification data of the individual identifier 24 read in the warehouse-in of the component C, the identification data of the unified identifier 25 is output, and the unified identifier 25 is assigned to each of the plurality of components C in the warehouse-in.

[ Effect ]

As described above, according to the present embodiment, the individual identifier 24 of the reel 23 is converted into the uniform identifier 25. In this way, when identifying a plurality of reels 23 delivered from a plurality of component suppliers, the identification can be performed by a single identification process. Therefore, occurrence of errors is suppressed in the recognition processing. In addition, the recognition process is simplified, and the reduction in manufacturing efficiency of the electronic device is suppressed.

The identification data of the individual identifier 24 includes the type of the component C held in the reel 23, the serial number of the component C, and the number of the components C. The identification data of the uniform identifier 25 includes at least one of the type of the component C held in the reel 23, the serial number of the component C, and the number of the components C. The identification data of the uniform identifier 25 includes one or both of the type of the component C held in the reel 23, the serial number of the component C, and the number of the components C, and thus the amount of information of the identification data included in the uniform identifier 25 is smaller than the amount of information of the identification data included in the individual identifier 24. Since the plurality of formats are unified into one format in the unified identifier 25, the component C held on the reel 23 can be determined based on the unified identifier 25 even if the amount of information included in the identification data is small.

The reading device 33 reads the individual identifier 24 in the elevator device 7. Since the individual identifier 24 is read during the reel 23 is put in storage, the identification process can be efficiently performed before the reel 23 is put in storage.

The assigning device 35 assigns the uniform identifier 25 to the reel 23 in the elevator device 7. Since the reel 23 is assigned the uniform identifier 25 during the storage, the reel 23 to which the uniform identifier 25 is assigned can be stored.

The detecting device 34 detects the component C in the elevator apparatus 7. Since the uniform identifier 25 is assigned during the warehouse-in of the reel 23, the component C can be specified before the warehouse-in of the reel 23.

Based on the detection data of the detection device 34 and the component data, the identification data of the uniform identifier 25 is output. Even if the reel 23 to which the individual identifier 24 is not given is delivered from the parts supplier, the reel 23 can be given the uniform identifier 25.

The detection data of the detection device 34, the component data, and the identification data of the uniform identifier 25 are collated to determine whether the uniform identifier 25 is given to the correct reel 23. Accordingly, the assignment of the uniform identifier 25 to the wrong reel 23 is suppressed. When the uniform identifier 25 is given to the wrong reel 23, the notification device 38 operates. Thus, the operator WM can recognize that the uniform identifier 25 is given to the wrong reel 23.
