The trace forward search unit 32 accesses the traceability management server 4, refers to the traceability information database 27, and performs a trace forward search (identification of a product in which the defective part is used).

  As a result, when a problem occurs in a certain product or product, the manufacturing number (lot number) of the part in which the problem has occurred is identified by the traceback search, and then the trace is performed from the manufacturing number (lot number) of the specified part. All products using defective parts can be identified by forward search.

  Hereinafter, the operation of the traceability management system will be described with reference to FIGS. FIGS. 4 to 6 are flowcharts showing a work procedure in which each worker creates a product, and FIGS. 7 to 13 are flowcharts showing an operation of each server. In this example, as shown in FIG. 2, a plurality of work tables 41 are provided in a certain process, and different products are created on each work table 41 and delivered to the production line 50 of the next process. Such a manufacturing form will be described. Each work table 41 is provided with a label (work table tag) on which a barcode indicating the work table number is printed, and a product manufactured on the work table 41 on the shelf of the work table 41 today. It is assumed that a product manufacturing instruction list (similar to a label) on which a barcode indicating the product number is printed is placed.

(Work instruction work: see Fig. 4)
In this traceability management system, an instructing operator who instructs work in each manufacturing process inputs a work table tag number from the work instruction PC 1 (step S101 in FIG. 4), and manufactures on the work table 41 in one day. The product numbers and the production numbers (number of lots) of all products are input in the order of production (step S102).

  The instruction worker repeats this input work until the input of all the product numbers manufactured on each workbench 41 is completed (step S103). When the input of work instructions for all work tables 41 is completed (Yes in step S103), a product manufacturing instruction list for each work table is printed and distributed to each work table 41 (step S104).

(Vehicle allocation: see Fig. 5)
The worker in charge of the cart takes out the first cart, for example, the cart 45, etc. from the cart storage area at the start of the work (step S111 in FIG. 5), and the work table 41 into which the cart 45 is loaded is changed. If the work table is changed (Yes in step S112), the work table tag attached to the cart 45 is changed to the work table tag to be changed. Replace (step S113). When the work table 41 to be dispatched is the same as the previous time, the work table tag is not replaced.

  Then, the worker in charge of the carriage moves the carriage 45 to the position of the reading device 2 and causes the reading device 2 to read the cart tag and the work table tag (step S114). Thereafter, the operator in charge of the cart distributes the cart 45 to the work table 41 (step S115).

(Manufacturing work on work bench: see Fig. 6)
The manufacturing worker places the product 51 to be manufactured by assembling the parts on the cart in the order in which the carts are allocated among the carts 45 to 48 (cart 45 → cart 46 → cart 47 → cart 48, etc.). A carriage is prepared (step S121 in FIG. 6), a manufacturing operation is started (step S122), and a plurality of parts prepared on the work table 41 are sequentially assembled to manufacture a product.

  When there are no lot controlled parts during the product manufacturing operation on the work table 41 (“No” in step S123), the parts are put into a predetermined place on the work table 41 and the parts mounting tag is attached to the parts of the cart 45. The tag is inserted into the tag pocket, which is a storage location for the attached tag (step S124). If there are no parts (“Yes” in step S123), the process proceeds to the next step S125.

  When all the parts are attached and the product 51 is completed (step S125), the completed product 51 is placed on the carriage 45 (step S126). This operation is repeated until the production of one lot of the product 51 is completed (step S127). When the production for one lot is completed (Yes in step S127), the manufacturing worker moves the carriage 45 to a place where it can be transferred in preparation for transfer (step S128). This operation is performed until all the operations on the work table 41 are completed.

(Discharge work of the cart from the work table: see Fig. 7)
The worker in charge of the carriage moves the produced product 51 from each worktable to the collective reading place (step S131 in FIG. 7). The product 51 is loaded on the cart 45 in units of lots (one lot).

At the collective reading place, the worker in charge of the carriage puts the carriage tag on the reading device 2 and causes the reading device 2 to read the carriage tag number from the carriage tag (step S132).
At the collective reading place, the worker in charge of the cart confirms the tag pocket of the cart 45, and if a component mounting tag is contained in the tag pocket ("Yes" in step S133), the component mounting tag contained in the tag pocket. Is collected (step S134), that is, taken out, the component mounting tag is applied to the reading device 2, and the component mounting tag number is read from the component mounting tag by the reading device 2 (step S135).

  If there is no component mounting tag in the tag pocket of the carriage 45, the operation proceeds to the next operation step S136. And all the component attachment tags in the trolley | bogie 45 are collect | recovered, and the said operation | work is repeated until a component attachment tag number is read.

  Then, after the product attachment tag is read (step S136), the product attachment tag is put into the tag pocket of the carriage 45 (step S137). Thereafter, the operator in charge of the cart pays out (moves) the cart 45 to the production line 50 of the upper process (step S138).

Next, the operation order information creation operation of this traceability management system will be described with reference to FIG.
In the manufacturing management server 3 in the work table work process, when the work table number is key-input by the work instruction operation from the work instruction PC 1 (step S141 in FIG. 8), the work order information creation unit 12 is input. The work table number is stored in the memory 11 (step S142). Next, when the manufactured article number is input (step S143), the manufactured article number is stored in correspondence with the work table number in the memory 11 (step S142). . When the production quantity (number of lots) is further input (step S144), the work sequence information creation unit 12 stores the production quantity (number of lots) in the memory 11 (step S145).

  Subsequently, the work order information creating unit 12 issues a new production number by referring to the production number issuer register in the production number issuer register storage unit 13 (step S146), and the memory corresponding to the manufactured article number. 11 (step S142).

  Then, the work order information creation unit 12 registers the work order information held in the memory 11 at the end of the work order management information in the work order management information storage unit 14 (step S147). The above step S processing is repeated until the processing for all the input quantities is completed. The processes in steps S146 to S147 are repeated until the work instruction for all product numbers manufactured on the workbench 41 is completed.

Next, the dispatch order information creation operation of this traceability management system will be described with reference to FIG.
When the work table tag is input from the reader 2 (step S151 in FIG. 9), the dispatch order information creation unit 16 holds the work table number in the memory 11 (step S152).

  Subsequently, when a cart tag is input (step S153), the dispatch order information creation unit 16 stores the cart number in association with the work table number in the memory 11. Thereafter, the dispatching order information creation unit 16 deletes the cart management information of the entered cart number from the cart management information storage unit 19 (step S154).

  Then, the dispatch order information creation unit 16 registers the dispatch order information stored in the memory 11 at the end of the dispatch order management information in the dispatch order management information storage unit 17 (step S155).

Next, the cart information creation operation of the traceability management system will be described with reference to FIG.
The cart information creation unit 18 checks whether or not the work order management information is stored in the work order management information storage unit 14 at predetermined time intervals (step S161 in FIG. 10). When the work order management information is stored in the information storage unit 14, that is, when the work order management information exists (Yes in step S161), the work order management information registered earliest is read into the memory 11.

  Next, the cart information creation unit 18 checks whether or not the dispatch order management information having the same work table number as the work order management information read into the memory 11 is stored in the dispatch order management information storage unit 17 (step S162) When the dispatch order management information is stored in the dispatch order management information storage unit 17 (Yes in step S162), the information registered earliest is read into the memory 11. Note that if the dispatch order management information having the same work table number as the work order management information read into the memory 11 is not stored, the process is terminated.

  Then, the cart information creation unit 18 registers the cart management information stored in the memory 11 at the end of the cart management information in the cart management information storage unit 19 (step S163).

  After the registration, the cart information creation unit 18 deletes (deletes) the used work order management information from the work order management information storage unit 14 (step S164), and the used vehicle order management information storage unit 17 Is deleted (deleted) from (step S165).

  Next, the operation of this system from reading of a cart tag to creation of component information will be described with reference to FIG.

  At the start of work, the dispatcher dispatches a desired one of the carts 45 to 48 stopped at the cart storage area 40, for example, the top cart 45 to the work table 41. At this time, the dispatcher moves the cart 45 to the position of the reading device 2 and causes the reading device 2 to read the cart tag of the cart 45 and the work table tag of the work table 41.

  When the reading device 2 reads the cart tag number and the work table tag number, the reading device 2 transmits the cart tag number and the work table tag number to the manufacturing management server 3. Then, the dispatch order information creation unit 16 of the manufacturing management server 3 is activated.

  The dispatching order information creation unit 16 that has started up reads the cart tag number from the reading device 2 (step S171 in FIG. 11). And the dispatch order information creation part 16 memorize | stores the read cart tag number in the memory 11 (step S172). In the memory 11, cart tag numbers are stored in the order received from the reading device 2.

  Subsequently, the dispatching order information creation unit 16 searches for the cart management information in the cart management information storage unit 19 using the cart number stored in the memory 11 as a key, and the cart number is the highest among the same work platform numbers. By checking whether or not the data is registered early, it is confirmed whether the order of dispatch is correct or not (step S173).

  As a result of this check, if the dispatch order is correct (Yes in step S173), the dispatch order information creation unit 16 reads the work table number and the product information from the carriage management information storage unit 19 and associates them with each other in the memory. 11 to store.

  As a result of the check, if the dispatch order is incorrect (No in step S173), the dispatch order information creation unit 16 executes an error process and ends the process. Error processing means outputting an error by display or buzzer.

  When an error is output, the worker searches for a carriage other than the carriage 45 registered first on the work table 41, for example, the carriages 46 to 48, and again applies the carriage tag to the reader 2 to read the carriage tag number and perform processing. Execute.

  When the work table number and the product information are stored in the memory 11, the process traceability information creation unit 21 searches the work table input part management information storage unit 23 using the work table number stored in the memory 11 as a key, The part number of the product configuration management master 22 of the manufactured article number stored in the memory 11 is extracted from the worktable input part management information, and used part information is created (step S174) and stored in the memory 11 (step S175).

  The process traceability information creation unit 21 creates component part information from the manufactured part information and the used part information stored in the memory 11 (step S176), and registers them in the traceability information database 27 through the LAN 6 (step S177).

Next, the process traceability information generation operation by the component mounting tag will be described with reference to FIG.
When the component attachment tag placed in the carriage 45 is applied to the reader 2, the component attachment tag number is read by the reader 2 and input to the manufacturing management server 3 as information on the component attachment tag (step S181).

  Then, in the manufacturing management server 3, the process traceability information creation unit 21 stores the component attachment tag number input from the reading device 2 in the memory 11 (step S182).

  The process traceability information creation unit 21 searches the inter-process linkage information database 26 of the traceability management server 4 using the component attachment tag number stored in the memory 11 as a key, and reads and uses the product information of the corresponding component attachment tag number. Stored in the memory 11 as component information.

  That is, the process traceability information creation unit 21 converts the component mounting tag number into used component information (product number and manufacturing number) which is product information (step S183) and stores it in the memory 11 (step S184).

  The process traceability information creating unit 21 creates component part information from the manufactured part information and the used part information stored in the memory 11 (step S185), and registers it in the traceability information database 27 through the LAN 6 (step S186).

  Further, the process traceability information creation unit 21 creates new worktable input parts information including information on the changed parts from the worktable number and the used parts information stored in the memory 11, and provides worktable input parts management information. Registration (workbench input part change registration) is performed in the storage unit 23 (step S187).

  After registration, the process traceability information creation unit 21 deletes the inter-process linkage information of the used traceability management server 4 (step S188).

  Thereafter, the above processing is repeated for the component mounting tag numbers read from the component mounting tags of the same cart 45, and when all the component mounting tag numbers have been processed (Yes in step S189), the process traceability information creating unit 21 determines the process traceability. The information generation process ends.

Next, the process traceability information generation operation by the product attachment tag will be described with reference to FIG.
When the product attachment tag number read by the reading device 2 is input to the production management server 3 (step S191), in the production management server 3, the process traceability information creation unit 21 stores the product attachment tag number in the memory 11. Store (step S192).

  Then, the process traceability information creating unit 21 creates inter-process linkage information from the product attachment tag number stored in the memory 11 and the manufactured part information already captured in the memory 11, and the inter-process linkage of the traceability management server 4. Register in the information database 26 (step S193).

Here, the operation of the entire traceability management system will be described.
In this traceability management system, when a work order instruction from the work instruction PC 1 to each work table 41 is input, the work order information creating unit 12 is activated in the manufacturing management server 3.

The work order information creating unit 12 creates work order management information for each work table 41 with reference to the production number issuing book in the production number issuing book storage unit 13 and stores the work order management information in the work order management information storage unit 14.
Further, when the work table tag and the cart tag are input from the reader 2, the dispatch order information creating unit 16 is activated. The activated dispatch order information creating unit 16 creates the dispatch order management information by associating the cart number and the work table number, and stores them in the dispatch order management information storage unit 17.

When both the work order management information for each work table 41 and the dispatch order management information for the trucks 45 to 48 are obtained in this way, the car information creation unit 18 is activated.
The cart information creation unit 18 creates cart management information from the work order management information of each work table 41 and the dispatch order management information of the carts 45 to 48 and stores the cart management information in the cart management information storage unit 19. Further, the cart information creation unit 18 deletes the work order management information and the dispatch order management information used when creating the cart management information from the respective storage units.

  In the operation of paying out the trolley 45 from the work table 41 to the manufacturing line 50 of the upper process, when the trolley tag number, the part mounting tag number, the product mounting tag number, etc. are input from the reader 2 at the installation location in the middle of transfer, The process traceability information creation unit 21 of the manufacturing management server 3 is activated.

  The activated process traceability information creation unit 21 includes cart management information in the cart management information storage unit 19, product configuration information in the product configuration management master 22, and workbench input component management in the workbench input component management information storage unit 23. The product number and serial number of the product being transferred are obtained from each tag number by referring to the information and the inter-process linkage information of the lower process of the inter-process linkage information database 26 managed by the traceability management server 4, and manufactured. Create inter-process linkage information consisting of component information (component information consisting of product number and manufacturing number) and tag number and product information (manufactured product number and product manufacturing number) In 41, information on the parts actually put in to manufacture the product is generated, and the worktable input parts management information in the worktable input parts management information storage unit 23 is updated.

  Further, the process traceability information creation unit 21 issues a deletion instruction (chain line 62 in FIG. 3) to the traceability management server 4 and inter-process linkage information of the lower processes of the inter-process linkage information database 26 used in the process traceability information generation process. Is deleted.

  Then, the component information and inter-process linkage information created by the process traceability information creating unit 21 are transferred from the manufacturing management server 4 to the traceability management server 4 via the LAN 6.

  In the traceability management server 4, the passed component information is stored in the traceability information database 27. Further, the inter-process linkage information of each manufacturing process is stored and managed in the inter-process linkage information database 26 in a lump.

  When the key input for the traceback search is performed from the search PC 5, the traceback search unit 29 is activated. The traceback search unit 29 refers to the traceability information database 27 based on the key-input information, performs a traceback (specification of the manufacturing number of a part used in the defective product), and searches for the traceback result in the search PC 5. Display on the screen.

  Further, when a key input for the trace forward search is performed from the search PC 5, the trace forward search unit 32 is activated. The trace forward search unit 32 refers to the traceability information database 27 based on the key input information, performs a trace forward (specification of a product in which the defective part is used) search, and displays the trace forward result on the screen of the search PC 5. To do.

  With this search function, if a problem occurs in a product, the manufacturing (lot) number of the part in which the problem has occurred is identified by traceback, and all products that use the defective part and the defective product are identified by trace forward. Can be identified.

Next, with reference to FIG. 14, the specific manufacturing procedure of a manufacturing process and the change of the process traceability information accompanying a change of components are demonstrated.
In FIG. 14, the product number (A1) indicates the lot number 1 of the manufactured article number A. Similarly, the part number is composed of a part number and a lot number.

[1] Dolly management information is created from work instruction input and dolly allocation information. In the dolly management information, the dolly (D1) corresponds to the product (A1), and the dolly (D2) and the product (A2) correspond to each other. Correspondingly, the cart (D3) corresponds to the product (B1). That is, the manufacturing management server 3 (the product (A1) is loaded on the cart (D1), the product (A2) is loaded on the cart (D2), and the product (B1) is loaded on the cart (D3). System) recognizes.

When the component mounting tag (T11) is read by the reading device 2,
[5] The manufacturing management server 3 refers to the inter-process linkage information (T11 = component X1) of the traceability management server 4 and replaces (converts) the tag number with the component information (X1), thereby constituting the component of the process traceability information It is additionally registered in the information as used part information of the product (A1). As a result, the component information of the process traceability information becomes (Product: A1, Component: X0, X1, Y0, Z0).
[6] Further, the manufacturing management server 3 updates the worktable input parts management information (X0) to (X1). As a result, the worktable input parts management information is (X1, Y0, Z0, W0).
[7] After the above process is completed, the manufacturing management server 3 deletes the inter-process linkage information (T11 = component X1) of the traceability management server 4.

When the product attachment tag (T1) is read by the reading device 2,
[8] The manufacturing management server 3 registers inter-process linkage information (T1 = product A1) in the process traceability information.

Next, when the cart number tag (D2) is read by the reading device 2 when the cart is paid out,
[9] The manufacturing management server 3 registers the product (A2) as the component information of the process traceability information and the product information of the inter-process linkage information.
[10] Also, in the worktable input parts management information (X1, Y0, Z0, W0) managed by the worktable 41, the component (X, Since Y, Z) is the target, the worktable input parts management information (X1, Y0, Z0) is registered as the used parts information of the product (A2) in the component information of the process traceability information.

Thereafter, when the component mounting tag (T12) is read by the reading device 2,
[11] The inter-process linkage information (T12 = part Y1) is referred to the traceability management server, converted into part information (Y1), and used as component information of the product (A2) in the component part information of the process traceability information. Register additional. As a result, the component information of the process traceability information is (Product: A2, Component: X1, Y0, Y1, Z0).
[12] The worktable input parts management information (Y0) is updated to (Y1). As a result, the worktable input parts management information is (X1, Y1, Z0, W0).
[13] After the above process is completed, the inter-process linkage information (T12 = component Y1) of the traceability management server is deleted.

Similarly, when the component mounting tag (T13) is read by the reading device 2,
[14] The manufacturing management server 3 refers to the inter-process linkage information (T13 = part Z1) with the traceability management server 4 and replaces (converts) the tag number with the part information (Z1) to configure the process traceability information. It is additionally registered in the component information as the used component information of the product (A2). As a result, the component information of the process traceability information becomes (Product: A2, Component: X1, Y0, Y1, Z0, Z1).
[15] Further, the manufacturing management server 3 updates the workbench input parts management information (Z0) to (Z1). As a result, the worktable input parts management information is (X1, Y1, Z1, W0).
[16] After the above process is completed, the manufacturing management server 3 deletes the inter-process linkage information (T13 = part Z1) that is no longer needed by the traceability management server 4. Thereafter, the tag T13 can be reused.

When the product attachment tag (T2) is read by the reading device 2,
[17] The manufacturing management server 3 registers inter-process linkage information (T2 = product A2) in the process traceability information.

Next, when the cart number tag (D3) is read by the reading device 2 when paying out the cart,
[18] The production management server 3 registers the product (B1) as the component information of the process traceability information and the product information of the inter-process linkage information.
[19] In addition, in the worktable input part management information (X1, Y1, Z1, W0) managed by the worktable 41, the component (X, Therefore, the manufacturing management server 3 registers the worktable input parts management information (X1, Y1, W0) as the used parts information of the product (B1) in the component information of the process traceability information. .

When the component mounting tag (T14) is read by the reading device 2,
[20] The manufacturing management server 3 refers to the inter-process linkage information (T14 = part X2) with the traceability management server, is converted into part information (X2), and is converted into the component information of the process traceability information as a product (B1 ) Used part information. As a result, the component information of the process traceability information becomes (Product: B1, Component: X1, X2, Y1, W0).
[21] Further, the manufacturing management server 3 updates the worktable input parts management information (X1) to (X2). As a result, the worktable input parts management information is (X2, Y1, Z1, W0).
[22] After the above process is completed, the manufacturing management server 3 deletes the inter-process linkage information (T14 = component X2) of the traceability management server 4.

When the product attachment tag (T3) is read by the reading device 2,
[23] The manufacturing management server 3 registers inter-process linkage information (T3 = product B1) in the process traceability information.

  As described above, according to the traceability management system of this embodiment, when the parts used in the work of the work table 41, which is one of the manufacturing processes, and the products manufactured from the parts are transported to the manufacturing line 50. The reading device 2 installed at a predetermined position in the middle of reading reads the tag of the cart 45 (cart tag), the tag of the work table 41 (work table tag), and the added component mounting tag, and uses the tag information as a manufacturing management server. 3, in accordance with the work order instruction received and inputted in advance, the component information and inter-process linkage information of the product to be conveyed are created and stored in the traceability management server 4, so that the work table 41 and the production line 50 can be stored. It is possible to reliably perform traceability management, which is often interrupted.

In addition, parts and products are managed in lot units, moved between lots, and the inter-process information is linked with tags attached to the carts 45 to 48 for transferring products, so that the fixed number is The assigned tag can be reused and used, and it is possible to save the tag resources that have conventionally been required to be attached to each individual part or product.
Further, the product mounting tag 44 (for reusability) placed in the tag box 43 at the position of the tag reader 2 installed on the way of transporting the product between the work table 41 and the production line 50 by the carriage 45. Tag is read as one of the inter-process linkage information when it is put into the cart 45, so that the reading device 2 is installed on each work table 41, and the tag is attached to a large number of parts and products to be assembled. Compared with reading, it is possible to reduce the installation cost of the reading device 2 and the tag reading work man-hours.

(Second Embodiment)
In the first embodiment described above, the inter-process linkage information is managed only by the tag information and the product information (product number / manufacturing number). Here, a case where intermediate conversion information having a unique number is provided will be described.

  In the first embodiment described above, the inter-process linkage information is managed by tag information and product information (product number / manufacturing number), and the component mounting tag number read by the reading device 2 is the component on the manufacturing management server 3 side. Information (product number / manufacturing number) is converted and managed as worktable input parts information, and product information (product number / manufacturing number) and used parts information (article number / manufacturing number) are generated as component information of process traceability information And sent to the traceability management server 4.

  However, in this case, in order to manage the product number and the production number so that they do not become the same number for a long time globally, a large number of digits may be taken, and in some cases, it may be a few tens of digits.

  In addition to acquiring traceability information, the manufacturing management server 3 may control manufacturing of the process in real time, and it is necessary to reduce performance degradation due to acquisition of traceability information as much as possible. For this purpose, it is necessary to compress the amount of traceability information handled by the manufacturing management server 3.

  Therefore, in the second embodiment, the inter-process linkage information (tag information and product information) sent from each manufacturing management server 3 is stored at the manufacturing base for a certain period (for example, about one day) by the traceability management server 4. A unique number (for example, date + serial number) is issued, and the issued number (for example, date + serial number) is added and managed.

  Each manufacturing management server 3 manages a unique number indicating inter-process linkage information instead of a manufacturing number as input part information, and changes between used part information (part number / manufacturing number) of component part information of process traceability information. The component information of the process traceability information is created using the unique number indicating the linkage information and sent to the traceability management server 4.

  The traceability management server 4 converts the used part information of the component information of the traceability information received from each manufacturing management server 3 from the unique number indicating the inter-process linkage information to the used part information (part number / manufacturing number), The part information is managed in the traceability information database 27 as product information (article number / manufacturing number) and used part information (article number / manufacturing number).

  According to the second embodiment, while avoiding tag operation restrictions when using reused tag information as it is, the amount of data handled in a production management system with high performance requirements is reduced, and performance degradation is suppressed. The amount of communication data between the manufacturing management server 3 and the traceability management server 4 can be reduced, and the network load can be reduced.

(Third embodiment)
In the above-described first embodiment, the truck number and the work bench number to be used are associated with each other in the dispatch work, and the truck can be used on any work bench. However, in actual operation, the product manufactured on the work bench 41 is transferred. In many cases, the operation order is fixed to the carts 45 to 48 used for the work table 41 according to the method. Here, the case where the carts 45 to 48 used for the work table 41 and the order of use is fixed will be described.

  As in the first embodiment, in order to relate the cart number to the product number of the product on the work table 41 and use it for checking the production order when the cart is paid out, the reading device 2 is used one by one at the time of vehicle allocation work. It is necessary to read the carriage number and the work bench number to be used by the reading device 2 and relate them to each other, which increases the man-hours at the time of dispatch.

Therefore, in the third embodiment, the cart used on the work table and the order of using the cart are fixed, and the cart number is set as the work table number + sequential number.
The trolley number is set to work platform number + sequential number, the work platform number is not read when the trolley is paid out, and the trolley information creation unit 18 and the process traceability information creation unit 21 are activated by reading only the trolley number.

  According to the third embodiment, it is possible to read the cart number and the work table number to be used by the reading device 2 at the time of dispatching, and to reduce the number of work steps to be related.

  Here, with reference to FIG. 15 and FIG. 16, the difference in the installation cost of the reading device between the general management method using the tag and the traceability management system will be described. The general management method is a method of generating product component configuration information by comparing, for example, a product creation time and a component input time.

  In comparing each other, the product “01” using the parts X to Z on the work table 41a in a certain lower process, the product “02” using the parts A to C on the work table 41b, and the part L on the work table 41c. -N is used to manufacture the product "03", and the work table 41d is used to manufacture the product "04" using the parts S to U. It is to be transferred to the input places 71-74.

In the case of a general management method, as shown in FIG. 15, it is necessary to install one reading device 2 on each of the work tables 41a to 41d in order to acquire input part information on each work table.
Further, it is necessary to install one reading device 2 for inputting input start information at each input place 71 to 74 of the line F of the next process which is a transfer destination of each product 54 to 57.

Further, in the line F, an end portion of the line F includes a reading device 2 for inputting manufacturing start information of the product of the line F and a reading device 2 for inputting manufacturing end information of the product of the line F. It is necessary to install in.
Therefore, the required number of installations that need to install the reader 2 in the lower process and the upper process is 10. In the case of a general management system, the required number of installations increases as the number of work tables 41 for manufacturing products in the lower process increases.

On the other hand, in the case of the traceability management system, as shown in FIG. In addition to this, it is only necessary to attach a tag of a part to be newly input to the product when a part lot change occurs.
Moreover, it is only necessary to install one reading device 2 at the production end location in the next upper process line F. Therefore, in this traceability management system, the necessary number of installations that need to install the readers 2 in the lower process and the upper process is always two regardless of the increase in the number of work tables, that is, the number of expensive readers 2 installed. Can be significantly reduced, and the system construction cost can be kept low.

  In addition, this invention is not limited only to the said embodiment, You may deform | transform a component in the range which does not deviate from the summary in an implementation stage. For example, each component may be realized by a program installed in a storage such as a hard disk device of a computer, or the program is stored in a storage medium such as a computer-readable CD-ROM, and the program is stored in the storage medium. You may implement | achieve by making a computer read from. Further, the configuration may be realized by distributing and storing the constituent elements in different computers connected via a network and communicating between the computers in which the respective constituent elements function.

  In addition, various inventions can be configured by appropriately combining a plurality of components disclosed in the embodiment. For example, some components may be deleted from all the components shown in the embodiment. Furthermore, constituent elements over different embodiments may be appropriately combined.
