  In the component assembling process, each manufacturing history for each tag 30 (manufacturing history storage device for each part) issued in association with each temporarily-joined part A, temporarily-joined part B, torque-tightening part C, etc. Data is recorded. Each tag 30 is transported to the assembly and assembly production line, which is the next production line, together with each of the temporary connection parts A, temporary connection parts B, and torque fastening parts C associated therewith.

  In the assembly process, the manufacturing history data of each tag 30 is read and checked when each temporary connection part A, temporary connection part B, and torque tightening part C are received.

  In addition, manufacturing history data and the like written to the tag 30 issued to each component are written and merged into the tag 30 (aggregate manufacturing history storage device) issued to the wire harness 20. After that, the tag 30 issued for each component is collected. Furthermore, the manufacturing history data in the present assembly process is additionally written to the tag 30 issued to the wire harness 20.

  Then, the tag 30 issued to the wire harness 20 is conveyed to the next process line together with the wire harness 20.

  In the next water stop process, when the wire harness 20 is received, the tag 30 is read and manufacturing history data and the like are checked. Then, manufacturing history data in the water stop process is additionally written to the tag 30.

  In the final overall inspection process, the manufacturing history data stored in the tag 30 associated with the wire harness 20 is read and stored in a predetermined database in association with the manufacturing number unique to each wire harness 20. . Thereafter, the production number unique to the wire harness 20 is associated with the production history data and managed on the database. In this step, the tag 30 issued to the wire harness 20 is collected.

<Description of tag issuing device and each production line>
Hereinafter, the tag issuing device and each production line in the above steps will be described in more detail.

<Tag issuing device>

  The tag 30 is a so-called wireless tag or the like. When a radio wave signal is received via the antenna coil 31, the received signal is given from the transmission / reception unit 32 to the control unit 34 via the demodulation circuit 33. The control unit 34 is connected to the memory 35 and writes predetermined data into the memory 35 in accordance with the received signal. Alternatively, the control unit 34 reads predetermined data in the memory 35 according to the received signal, outputs the predetermined data from the modulation circuit 36 to the antenna coil 31 via the transmission / reception unit 32, and outputs the predetermined data from the antenna coil 31. Output radio signal including.

  The tag issuing device 40 is a device that issues a tag 30 in which a product number is written, and includes a product number receiving unit 42, a tag issuing control unit 44, and a tag reader / writer device 46. Here, the product number is a number (manufactured product identification code) indicating the type of a component to be manufactured or assembled (temporary component A, temporary component B, torque tightening component C, etc.) or a product (wire harness 20). is there.

  In this embodiment, a printer device is incorporated in the tag issuing device 40, and when the product number is written to the tag 30, the product number and the like are printed on the surface of the tag 30 by the printer device. ing. Thereby, recording of information such as the product number for the tag 30 and printing of the display information for the tag 30 can be performed at the same timing, and inconsistency between the two information can be prevented. In this case, a rewritable sheet may be attached to the surface of the tag 30 and a rewritable printer device may be used as a printer device so that display information on the surface of the tag 30 can be repeatedly printed and erased.

  When the product number receiving unit 42 receives a product number to be issued from an input device such as a keyboard or a numeric keypad or another terminal device, the product number receiving unit 42 outputs the received product number to the tag issue control unit 44.

  The tag reader / writer device 46 is a reader / writer for a so-called wireless tag, and performs wireless communication with the tag 30 to transmit a command for writing predetermined data to the tag 30 to the tag 30. Write predetermined data or receive predetermined data from the tag 30 and read the data of the tag 30.

  When the product number to be issued is instructed through the product number receiving unit 42, the tag issue control unit 44 writes the product number instructed through the tag reader / writer device 46 into the tag 30. Thereby, the tag 30 in which the designated product number is written is issued.

  In the tag issuing device 40, the tag 30 is issued in association with each of the temporary connection part A, the temporary connection part B, and the torque tightening part C, which are component parts. Each tag 30 has a product number (for example, “XXX-001”, “XXX-002”, “XXX-003”) corresponding to the temporarily-attached part A, the temporarily-attached part B, and the torque-tightening part C. Etc.) is written.

  Moreover, in the tag issuing device 40, the tag 30 is issued in association with the wire harness 20 that is a collective product. A product number (for example, “ΔΔΔ-001”, etc.) corresponding to the wire harness 20 is written on the tag 30.

  These tags 30 are managed by being physically associated with the temporary parts A, the temporary parts B and the torque fastening parts C, and the wire harness 20, and can be transported together therewith. As a configuration for physically associating each tag 30 with the temporary connection part A, the temporary connection part B and the torque tightening part C, and the wire harness 20, for example, each tag 30 is temporarily connected with the temporary connection part A, the temporary connection part B, and the torque. Examples include a configuration in which the fastening component C and the wire harness 20 are tied with a string or the like, and a temporary attachment component A, a temporary connection component B and a torque fastening component C, and a configuration in which the tag 30 corresponding to the case housing the wire harness 20 is attached.

<Preliminary part A production line>
FIG. 6 is a block diagram showing a continuity inspection apparatus and a temporary connection part A production management apparatus provided in the temporary connection part A production line, and FIG. 7 is a schematic perspective view showing the temporary connection part A production management apparatus.

  This temporary connection part A production line is a production line for manufacturing the temporary connection part A, and includes a continuity inspection apparatus 50 and a temporary connection part A production management apparatus 60.

  The continuity test apparatus 50 includes a plurality of connector connection parts 52 connectable to the connector 14 and a continuity test part 54. The connector connecting portion 52 is configured to be connectable to the connector 14 of the temporary connection part A, and an inspection pin capable of contacting the connector terminal 12 of the connector 14 is incorporated therein. Then, the connector connection portion 52 is connected to the connector 14 so that conduction is obtained between each connector terminal 12 and the inspection pin.

  Each connector connection part 52 is connected to the continuity inspection part 54 through a plurality of wires (only one is shown in FIG. 6) associated with each inspection pin. In the continuity inspection unit 54, between the connectors 14, the continuity between the connector terminals 12 and the non-conduction state (conduction pattern) are set. Note that this conduction pattern is set according to the wiring mode of the temporary component, that is, the product number.

  And in the state which connected each said connector connection part 52 to each corresponding connector 14, the conduction | electrical_connection between each connector terminal 12 and a non-conduction state are test | inspected, and the conduction | electrical_connection test of the temporary connection component A is performed. As a result, when the connector terminal 12 is attached at an incorrect position, or when the connector terminal 12 is disconnected in the middle, a conduction failure is detected.

  When the continuity test is completed, information for specifying a defective position when the continuity state is good or bad is given to the temporary component A manufacturing management apparatus 60.

  The temporary connection part A manufacturing management device 60 is a device for writing manufacturing history data in the manufacturing line to the tag 30, and includes a management control unit 62, a storage unit 63, an input unit 64, a display unit 65, A reader / writer device 66.

  The management control unit 62 is a general microcomputer including a CPU, a ROM, a RAM, and the like, and all of the arithmetic operations are executed by a software program stored in advance. Then, the continuity test result, a predetermined instruction and data through the input unit 64 are input to the main management control unit 62, and the main control unit 62 writes and reads data to and from the storage unit 63 and passes through the reader / writer device 66. Writing and reading of the tag 30, product number instruction to the continuity testing device 50, display control for the display unit 65, and the like are performed. Specific operations performed by the management control unit 62 will be described in detail later.

  The input unit 64 is an input unit including an input switch and the like, and through this input unit 64, a predetermined operation instruction, an operator name, the fact that there is a defect, the content of the defect, and a check when there is a defect are confirmed. The person who has performed (hereinafter simply referred to as the confirmer) or the like is input. It should be noted that these input contents (particularly, the operator name, the confirmer, etc.) may be input via the reader / writer device 66 described later.

  The display unit 65 is an element including a light emitting unit, a liquid crystal display device, or the like. The display unit 65 confirms the input contents, displays a predetermined error, and other work contents (for example, continuity check). Result) is displayed.

  Similar to the tag reader / writer device 46, the reader / writer device 66 performs wireless communication with the tag 30 and writes predetermined data to the tag 30 or reads predetermined data from the tag 30. It is.

  The reader / writer device 66 includes a reader / writer main body 66b (writing unit, history reading unit) including an antenna unit for wireless communication, a transmission / reception circuit, and the like in a main body unit of a case body 66a (set unit) opened at the top. It is supposed to be installed configuration. Then, by setting the tag 30 so as to be housed in the case body 66a, wireless communication is performed with the tag 30, and data is written to and read from the tag 30.

  In the temporary connection part A production line, the continuity inspection device 50 and the input unit 64 function as a first production line device. In particular, the continuity inspection device 50 is an inspection device that performs inspection on the production line. The input unit 64 functions as an input device that accepts inputs such as defective content and a confirmer.

  FIG. 8 is a flowchart for explaining the operation of the temporary connection part A manufacturing management apparatus, and FIG. 9 is a diagram showing an example of manufacturing history data written on a tag in the manufacturing line.

  First, in step S1, it is determined whether there is an operator setting. If there is no operator setting, step S1 is repeated. On the other hand, if the operator is set through the input unit 64, the process proceeds to the next step S2.

  In step S <b> 2, it is determined whether or not the tag 30 is set in the reader / writer device 66. If communication with the tag 30 is not established through the reader / writer device 66, step S2 is repeated. On the other hand, as a result of the operator setting the tag 30 in the reader / writer device 66, if communication is established with the tag 30, it is determined that the tag 30 is set, and the process proceeds to the next step S3.

  In step S3, an attempt is made to read out the product number registered in the tag 30 to determine whether the tag check has passed. As the tag check, here, for example, whether or not the product number is registered and whether or not the read product number is the correct product number (such as the product number to be manufactured in the present production line) is checked. Here, when it is unacceptable, it progresses to step S9, an error display is performed, it returns to step S2, and the following processes are repeated. On the other hand, if it is determined that the product number is registered, the read product number is correct, and the tag check is passed, the process proceeds to step S4.

  In step S4, the work start time and the worker are written in the tag 30, and the process proceeds to step S5.

  In step S5, the read product number is given to the continuity test apparatus 50, and the like. Thereby, in the continuity inspection apparatus 50, the inspection initial setting according to the product number is performed, and the inspection is started.

  In a succeeding step S6, it is determined whether or not there is an input operation indicating that there is a defect through the input unit 64. Here, for example, when the operator visually finds a defective part and inputs that there is a defect through the input unit 64, it is determined that there is a defect input operation, and the process proceeds to step S10. On the other hand, if it is determined that there is no defective input operation, the process proceeds to step S7.

  In step S <b> 7, it is determined whether the inspection has passed or failed based on the inspection result signal from the continuity inspection device 50. That is, when an operator connects each connector 14 to the corresponding connector connection portion 52 and conducts a continuity test using the continuity test apparatus 50, the test result is input to the temporary connection part A manufacturing management apparatus 60. Here, when it is determined that the inspection has failed, the process proceeds to step S10.

  If it is determined in step S6 and step S7 that there is a defect input operation or the inspection fails, the process proceeds to step S10. In step S10, it is determined whether or not there is a defect content input or a defect content confirmation input. If there is no such content, step S10 is repeated, and if there is an input, the process proceeds to the next step S11. For example, when it is determined that there is a defect input operation (see step S6), if the operator inputs defect contents (for example, whether or not the conduction state is good or bad) through the input unit 64, the process proceeds to the next step S11. Further, for example, after the continuity inspection device 50 determines that the inspection has failed (see step S7), the defect content (for example, a defective portion) is identified based on the inspection result signal from the continuity inspection device 50. When the worker confirms the content of the defect and inputs confirmation through the input unit 64, the process proceeds to the next step S11. By this step S10, the generated defect content is identified and confirmed.

  In step S11, it is confirmed whether or not there is an input from the confirmer. If there is no input from the confirmer, step S11 is repeated. If it is determined that there is an input from the confirmer, the process proceeds to the next step S12. For example, when the worker corrects the identified and confirmed defect and inputs the confirmer who has corrected the defect, the process proceeds to the next step S12. As for the confirmer here, it is preferable to advance to the next step S12 only when an authorized confirmer is set in advance and an authorized regular confirmer is input.

  In step S12, the defect content and the confirmer are recorded in the tag 30, the process returns to step S6, and the following processing is repeated.

  If it is determined in step S7 that the inspection has passed, the process proceeds to step S8. In step S8, the manufacturing history and work end time indicating that the continuity test has been passed are recorded in the tag 30, and the process ends.

  Note that the input unit 64 is configured to accept that the operation of this process is interrupted, and in steps S6, S7, and S10 to S12, if it is accepted that the operation is interrupted, the content of the defect or the like is added to the tag 30 as necessary. Then, the process may be terminated without recording a history of success or the like in the tag 30.

  After passing through the above manufacturing process, the tag 30 associated with the temporary component A includes at least a product number, an operator, a start time, an end time, and an inspection pass judgment in the process, as shown in FIG. Manufacturing history data is stored. Further, when an inspection failure occurs, a defect content, a confirmer, etc. are added to the manufacturing history data.

  The temporary connection part B is manufactured in a temporary connection part B manufacturing line configured in the same manner as the temporary connection part A manufacturing line.

<Torque tightening part C production line>
FIG. 10 is a block diagram showing a torque tightening device and a torque tightening component C production management device provided in the torque tightening component C production line.

  The torque tightening device 70 is a device for tightening the screw 19, and includes a screw tightening portion 72, a rotation driving portion 74 such as a servo motor for rotating the screw tightening portion 72, and the rotation driving portion 74. And a screw tightening controller 76 for controlling the driving of the motor. When the screw tightening unit 72 is rotationally driven, the torque tightening device 70 monitors the rotation amount and necessary torque by the rotation driving unit 74, the advance / retreat amount of the screw tightening unit 72, and the like. Then, when the screw tightening portion 72 does not rotate after reaching the original screw tightening start position, or when the rotation amount is relatively small or the advance / retreat amount is relatively small, the necessary torque becomes excessive and the screw tightening is finished. In some cases, a screw tightening failure is detected. Then, when the screw tightening is good or not, the torque required for screw tightening is given to the torque tightening part C manufacturing management device 60C.

  The torque tightening device 70 functions as a manufacturing processing device that performs manufacturing processing on the torque tightening part C manufactured in this manufacturing line, and also functions as an inspection device that inspects the quality of screw tightening during the manufacturing processing. To do.

  The torque tightening part C production management device 60C has the same configuration as the temporary component A production management device 60 except for the points described below. That is, a torque tightening device 70 is connected to the torque tightening part C production management device 60C in place of the continuity inspection device 50. As shown in FIG. 11, the manufacturing history data written in the tag 30 includes a product number, an operator, a start time, an end time, and screw tightening quality (manufacturing history). When the screw tightening is good, the necessary torque is added to the manufacturing history data. When the screw tightening is poor, the defect content and the confirmer are added to the manufacturing history data.

  Other configurations and operations relating to the torque tightening part C production management device are the same as those of the temporary component A production management device 60, and thus detailed description thereof is omitted here.

<Assembly assembly line>

  Each clamp holding jig 82 is installed at a position corresponding to the wiring path of the wire harness 20. The clamp holding jig 82 is configured to be able to set a clamp, and is configured to be able to detect the set state of the clamp by detection means such as a limit switch. The detection signal from each clamp holding jig 82 is given to the clamp inspection unit 84.

  The clamp inspection unit 84 inspects the attachment state of each clamp based on the detection signal from each clamp holding jig 82 and determines pass / fail. For example, when clamps are set on all necessary clamp holding jigs 82, it is determined that the mounting state is acceptable and no clamps are set on the necessary clamp holding jigs 82. Judge that it is a pass. Then, the pass / fail judgment result is given to the collective assembly manufacturing management apparatus 60D.

  The clamp attachment inspection device 80 functions as an inspection device that inspects the wire harness 20 manufactured on the production line.

  The assembly / assembly manufacturing management device 60D is generally configured in the same manner as the temporary connection part A manufacturing management device 60, and here, the main differences will be mainly described.

  That is, a clamp mounting inspection device 80 is connected to the assembly / manufacturing management device 60D instead of the continuity inspection device 50.

  As shown in FIG. 13, the reader / writer device 66D can read and write a plurality of tags 30 simultaneously. Accordingly, when a predetermined tag 30 is set on the reader / writer device 66D and the tag 30 is recognized and readable and writable, the other tag 30 is placed in front of the reader / writer device 66D. Is also recognized and can be read and written.

  Further, the assembly / assembly manufacturing management device 60D has a function of storing the manufacturing history data in the manufacturing line in the tag 30 in the same manner as the temporary connection part A manufacturing management device 60.

  In addition, as shown in FIG. 14, the storage unit 63 of the assembly / assembly manufacturing management device 60D stores product number data (necessary product number data) necessary for assembling a predetermined assembly product in this line. In addition, as shown in FIG. 15, data relating to the manufacturing history required for the part (necessary manufacturing history data) is stored. For example, in FIG. 14, the part numbers (for example, “xxx-001”, “xxx-002”) required for the assembly product having a predetermined part number (for example, “ΔΔΔ-001”). "," Xxx-003 ") are registered in a linked format. Further, for example, in FIG. 15, “predetermined process” as a necessary history for the part number (for example, “xxx-001”, “xxx-002”, “xxx-003”) of each part. The inspection manufacturing history (inspection pass, good screw tightening, etc.) in (process XX, process ΔΔ, process XX, etc.) is set to be necessary.

  The assembly / manufacturing production management device 60D has a function of checking whether the product is a necessary part by comparing the product number stored in each tag 30 with the necessary product number data. Moreover, it has the function to determine the inspection pass / fail in the previous process by collating the production history data stored in each tag 30 with the necessary production history data.

  Further, the assembly / assembly manufacturing management apparatus 60D has a function of merging manufacturing history data of each tag 30 associated with each part into one tag 30.

  FIG. 16 is a flowchart for explaining the operation of the collective assembly manufacturing management apparatus 60D for realizing the above functions.

  First, in step S21, it is determined whether or not there is an operator setting. If there is no operator setting, step S21 is repeated. On the other hand, when the operator is set through the input unit 64, the process proceeds to the next step S22.

  In step S22, it is determined whether or not the tag 30 is set in the reader / writer device 66. If communication with the tag 30 is not established through the reader / writer device 66, step S22 is repeated. On the other hand, when communication is established with the tag 30 as a result of the operator setting the tag 30 issued to the wire harness 20 in the reader / writer device 66D, it is determined that the tag 30 is set, Proceed to next step S23.

  In step S23, an attempt is made to read out the product number and manufacturing history registered in the tag 30 to determine whether the tag check has passed. As the tag check, here, for example, whether or not the product number is registered, whether the read product number is the correct product number (whether it is a product number to be manufactured in this production line, etc.) and the manufacturing history corresponding to the product number are satisfied. It is checked whether or not it has passed (previous process or passed in previous process). Here, when it is unacceptable, it progresses to step S34, an error display is performed, it returns to step S22, and the process after step S22 is repeated. On the other hand, if it is determined that the tag check is passed, the process proceeds to step S24.

  In step S24, the work start time and the worker are recorded in the tag 30, and the process proceeds to step S25.

  In step S25, based on the data shown in FIGS. 14 and 15, the product number required to manufacture the wire harness 20 and the manufacturing history required for the product number are determined, and the process proceeds to the next step S26.

  In step S26, the presence / absence of communication with another tag 30 is confirmed. If communication with another tag 30 is not established, step S26 is repeated. On the other hand, when the operator holds the tag 30 associated with the temporary connection part A, the temporary connection part B, the torque fastening part C, or the like over the reader / writer device 66D, communication is established with the other tags 30. It is determined that there is communication with another tag 30, and the process proceeds to the next step S27.

  In step S27, an attempt is made to read the product number and manufacturing history data stored in the other tag 30, and it is determined whether or not the tag check is successful. In the tag check pass / fail determination, for example, it is determined whether or not the product number is registered, whether or not the read product number is the required product number, and whether or not the read manufacturing history data satisfies the required manufacturing history. . If the determination result is unsuccessful, the process proceeds to step S35, an error is displayed, the process returns to step S26, and the processes after step S26 are repeated. On the other hand, if the determination result is acceptable, the process proceeds to step S28, and the read product number and manufacturing history data are written into the tag 30 issued to the wire harness 20 that is the aggregate product and merged. .

  In the next step S29, the presence or absence of other necessary product numbers is determined. Here, if it is determined that other parts are necessary based on the data shown in FIG. 14, the process returns to step S26, and the processes in and after step S26 are repeated to accept other parts. On the other hand, if it is determined that there is no other necessary product number, the process proceeds to step S30, the product number of the wire harness 20 read in step S23 is given to the clamp mounting inspection device 80, the inspection setting is performed, and the inspection start state It becomes. Thereby, the clamp mounting inspection apparatus 80 performs the inspection initial setting according to the said product number.

  In a succeeding step S30, it is determined whether or not there is an input operation indicating that there is a defect through the input unit 64. Here, for example, if the operator finds a defective part by visual observation and inputs that there is a defect through the input unit 64, it is determined that there is a defect input operation, and the process proceeds to step S36. On the other hand, if it is determined that there is no defective input operation, the process proceeds to step S32.

  In step S32, based on the inspection result signal from the clamp mounting inspection device 80, it is determined whether the inspection has passed or failed. That is, after the operator performs the bundling work of the wire harness 20, the clamps are attached, the clamps are set on the holding jig 82, and the attachment state of the clamps is inspected. Input to the management device 60D. If it is determined that the inspection has failed, the process proceeds to step S36.

  If it is determined in step S31 and step S32 that there is a defective input operation or the inspection fails, the process proceeds to step S36. In step S36, it is determined whether or not there is a defect content input or a defect content confirmation input. If these inputs are not present, step S36 is repeated. If there is an input, the process proceeds to the next step S37. For example, when it is determined that there is a defect input operation (see step S31), if the operator inputs the defect content (for example, defective mounting of the clamp) through the input unit 64, the process proceeds to the next step S37. Further, for example, after it is determined that the inspection has failed in the clamp attachment inspection device 80 (see step S32), the defect content (for example, whether the clamp attachment is good or bad) based on the inspection result signal from the clamp attachment inspection device 80. Etc.) is specified and displayed, and if the operator confirms the content of the defect and inputs confirmation through the input unit 64, the process proceeds to the next step S37. By this step S36, the generated defect content is identified and confirmed.

  In step S37, it is confirmed whether or not there is an input from the confirmer. If there is no input from the confirmer, step S37 is repeated. If it is determined that there is an input from the confirmer, the process proceeds to the next step S38. For example, when the worker corrects the identified and confirmed defect and inputs the confirmer who has corrected the defect, the process proceeds to the next step S38. As for the confirmer here, it is preferable to advance to the next step S38 only when an authorized confirmer is set in advance and an authorized regular confirmer is input.

  In step S38, the defect content and the confirmer are recorded in the tag 30, the process returns to step S31, and the following processing is repeated.

  If it is determined in step S32 that the inspection has passed, the process proceeds to step S33. In step S33, the manufacturing history and work end time indicating that the continuity test is passed are recorded in the tag 30, and the process is terminated.

  The input unit 64 is configured to be able to accept that the operation of this process is interrupted. In steps S31, S32, and S36 to S38, if it is accepted that the operation is interrupted, the content of the defect or the like is added to the tag 30 as necessary. Then, the process may be terminated without recording a history of success or the like in the tag 30.

  Thereby, for example, as shown in FIG. 17, the tag 30 associated with the wire harness 20 that is a collective assembly product in the production line includes at least a product number, an operator, a start time, an end time, Manufacturing history data including an inspection pass judgment is stored. Further, when the inspection fails, a confirmer or the like is added to the manufacturing history data.

  The tag 30 also stores manufacturing history data (see FIGS. 9 and 11) in the previous process.

<Water stop production line>
FIG. 18 is a block diagram showing a water-stopping agent application device and a water-stop production management device provided in the water-stop production line.

  This water stop production line is a production line for applying a water stop treatment to the wire harness 20 and includes a water stop agent coating device 90 and a water stop production management device 60E.

  The water stop agent coating apparatus 90 controls the application head 92, a water stop agent supply mechanism 94 for supplying a water stop agent such as a silicon water stop agent to the application head 92, and the water stop agent supply mechanism 94. Water-stop agent supply control unit 96.

  And in the state which arranged the water stop part of the wire harness 20 in the front end side of the application head 92, a water stop agent is apply | coated around the water stop part of the wire harness 20 by discharging a water stop agent from the application head 92. It has come to be. This water-stopping agent application device 90 determines that the application operation has failed when the amount of water-stopping agent supplied by one application is insufficient or when the operation is stopped due to a system abnormality or the like. Then, the result of the water-stopping agent application work is output and given to the water-stop manufacturing management device 60E. In addition, when the application work does not fail, information on manufacturing processing including the application amount of the water-stopping agent is given to the water-stop manufacturing management device 60E.

  The water-stopping agent application device 90 functions as a manufacturing processing device that performs manufacturing processing on the wire harness 20 manufactured in the manufacturing line, and also functions as an inspection device that inspects the quality of the water stopping that is the manufacturing processing. To do.

  The still water production management device 60E has the same configuration as the temporary connection part A production management device 60, and here, the description will focus on the main differences.

  That is, a water-stopping agent coating device 90 is connected to the water-stop manufacturing management device 60E instead of the continuity testing device 50. And the still water production management device 60E has a function of storing the production history data in the production line in the tag 30 in the same manner as the temporary connection part A production management device 60.

  In addition, the storage unit 63 of the water stoppage manufacturing management device 60E corresponds to the product number corresponding to the wire harness 20 with the manufacturing history required for the wire harness 20 (for example, the pass inspection of the clamp inspection). Necessary manufacturing history data is stored. And the still water manufacture management apparatus 60E reads the manufacture history data memorize | stored in the tag 30 matched with the wire harness 20, and collates this with the said required manufacture history data, and the pass / fail of the wire harness 20 is confirmed. It also has a function to determine.

  FIG. 19 is a flowchart for explaining the operation of the water stop production management device 60E realizing the above functions.

  First, in step S41, it is determined whether or not there is an operator setting. If there is no operator setting, step S41 is repeated. On the other hand, when the operator is set through the input unit 64, the process proceeds to the next step S42.

  In step S42, it is determined whether or not the tag 30 is set in the reader / writer device 66. If communication with the tag 30 is not established through the reader / writer device 66, step S42 is repeated. On the other hand, as a result of the operator setting the tag 30 in the reader / writer device 66, if communication is established with the tag 30, it is determined that the tag 30 is set, and the process proceeds to the next step S43.

  In step S43, an attempt is made to read the product number or the like registered in the tag 30 to determine whether or not the tag check is successful. As the tag check, here, for example, based on the presence / absence of product number registration, check whether the read product number is the correct product number (whether it is the product number to be manufactured in this production line, etc.) and the necessary manufacturing history data, A check is made as to whether the manufacturing history necessary for manufacturing the wire harness 20 having the product number is satisfied. Here, when it is unacceptable, it progresses to step S49, an error display is performed, it returns to step S42, and the following processes are repeated. On the other hand, if it is determined that the product number is registered, the read product number is correct, and the tag check is passed, the process proceeds to step S44.

  In step S44, the work start time and the worker are written in the tag 30, and the process proceeds to step S45.

  In step S45, the read product number is given to the water-stopping agent coating apparatus 90, the inspection setting is performed, and the inspection is started. Thereby, the water-stopping agent coating apparatus 90 performs the inspection initial setting according to the product number.

  In a succeeding step S46, it is determined whether or not there is an input operation indicating that there is a defect through the input unit 64. Here, for example, when the operator visually finds a defective part and inputs that there is a defect through the input unit 64 (such as a defective water stop operation), it is determined that there is a defect input operation, and step S50 is performed. Proceed to On the other hand, if it is determined that there is no defective input operation, the process proceeds to step S47.

  In step S <b> 47, it is determined based on the inspection result signal from the water-stopper coating device 90 whether the inspection has passed or failed. That is, when an operator performs a water-stopper application work with the water-stopper application device 90, the result of the operation (good or bad water-stopper application work, amount of water-stopper applied, etc.) Entered. If it is determined that the result is unacceptable based on this work result (for example, when the water stop work is interrupted, the amount of application is poor, or excessive), the process proceeds to step S50.

  If it is determined in step S46 and step S47 that there is a defect input operation or the inspection fails, the process proceeds to step S50. In step S50, it is determined whether or not there is a defect content input or a defect content confirmation input. If there is no such content, step S50 is repeated, and if there is an input, the process proceeds to the next step S51. For example, when it is determined that there is a defect input operation (see step S46), if the worker inputs defect details (for example, lack of water-stopper application, protrusion, etc.) through the input unit 64, the next Proceed to step S51. In addition, for example, after it is determined that the inspection has failed by the water-stopping agent application device 90 (see step S47), the defect content is specified and displayed based on the work result result signal from the water-stopping agent application device 90. If the worker confirms the content of the defect and inputs the confirmation through the input unit 64, the process proceeds to the next step S51. By this step S50, the generated defect content is identified and confirmed.

  In step S51, it is confirmed whether or not there is an input from the confirmer. If there is no input from the confirmer, step S51 is repeated. If it is determined that there is an input from the confirmer, the process proceeds to the next step S52. For example, when the worker corrects the identified and confirmed defect and inputs the confirmer who has corrected the defect, the process proceeds to the next step S52. As for the confirmer here, it is preferable to advance to the next step S52 only when an authorized confirmer is set in advance and an authorized regular confirmer is input.

  In step S52, the defect content and the confirmer are recorded in the tag 30, the process returns to step S46, and the following processing is repeated.

  If it is determined in step S47 that the inspection has passed, the process proceeds to step S48. In step S48, the manufacturing history indicating that the continuity test has been passed and the work end time are recorded in the tag 30, and the process ends.

  The input unit 64 is configured to be able to accept that the operation of this process is interrupted. In steps S46, S47, and S50 to S52, if it is accepted that the operation is interrupted, the content of the defect or the like is added to the tag 30 as necessary. Then, the process may be terminated without recording a history of success or the like in the tag 30.

  Thereby, the tag 30 associated with the wire harness 20 includes, for example, an operator in the production line, work start time, work flow time, manufacturing history data including a pass judgment of the coating work, and a defective coating work. If it occurs, the manufacturing history data to which the defect content, the confirmer, etc. are added is stored.

<Overall inspection line>
FIG. 20 is a block diagram showing an overall inspection management device provided on the overall inspection line and a data server device connected thereto.

  That is, the final overall inspection line is provided with the overall inspection management device 60F and the database server device 100.

  The overall inspection management device 60F has the same configuration as the temporary component A manufacturing management device 60, except that an optical mark reading device 68 (also referred to as OMR or bar code reader) is additionally provided.

  The database server device 100 is constituted by a so-called personal computer or the like, and a predetermined database is constructed in the storage device 102 of the database server device 100.

  The overall inspection management device 60F and the database server device 100 are communicably connected via a LAN communication line or the like.

  When the wire harness 20 is conveyed to the production line, the tag 30 associated with the wire harness 20 is set in the reader / writer device 66. Then, all manufacturing history data stored in the tag is read through the reader / writer device 66. At this time, when the manufacturing number assigned to the wire harness 20 is read through the optical mark reading device 67, a number obtained by adding a unique identification number to the manufacturing number is assigned to the wire harness 20. Thereby, all the manufacturing history data regarding the wire harness 20 is stored in the storage device 102 of the database server device 100 as a manufacturing history database in association with the manufacturing number unique to each wire harness 20.

  Thereby, the correspondence between each tag 30 and the wire harness 20 is released, and the tag 30 is collected.

  Subsequent inspection results such as appearance inspection and continuity inspection are managed in the manufacturing history database in association with the unique manufacturing number.

<Overall explanation>
An overall manufacturing procedure of the wire harness 20 in this management system will be described.

  First, the tag issuing device 40 issues tags 30 corresponding to the temporarily connected parts A, the temporarily connected parts B, and the torque tightening parts C.

  Then, in each of the temporary connection part A production line, the temporary connection part B production line, and the torque tightening part C production line, each temporary connection part A, temporary connection part B, and torque tightening part C are set with the tag 30 set. Manufacture and test. Then, each tag 30 includes manufacturing results including inspection results (pass / fail of continuity, pass / fail of torque tightening, etc.), input results (defect contents, confirmers, etc.) and manufacturing status (torque values, etc.) in each manufacturing line. Historical data is written. Of course, according to the work contents of each process, the contents of the manufacturing history data written in each tag 30 include the inspection results (pass / fail of conduction, pass / fail of torque tightening, etc.) by a predetermined manufacturing apparatus or inspection apparatus, and manual operation. Only one of the input results (defect contents) may be used.

  Then, each temporarily bonded part A, temporarily bonded part B, and torque tightening part C are transported to the next collective assembly production line together with the tag 30 associated with each.

  Further, the tag 30 is issued from the tag issuing device 40 to the wire harness 20 that is a collective assembly product. By setting the tag 30 in the reader / writer device 66D of the collective assembly production management device 60D in the collective assembly production line, the required part numbers and the necessary manufacturing history of each part number are determined.

  Then, the tag 30 corresponding to each of the temporary connection part A, the temporary connection part B, and the torque tightening part C is read by the reader / writer device 66D to determine whether it is a required part. It is determined whether the manufacturing history has passed. When these determination results are unacceptable, an error is displayed. This eliminates parts having product numbers other than the required product number. Moreover, even if the part number is required, the part that does not have the required manufacturing history is excluded.

  At the same time, the manufacturing history data stored in the tags 30 corresponding to the temporary parts A, the temporary parts B, and the torque tightening parts C are written and merged in the tags 30 corresponding to the wire harness 20. The

  And when each temporary connection component A, temporary connection component B, and torque fastening component C are received through the above, an operator will assemble these and manufacture wire harness 20. Further, the clamped state of the wire harness 20 is inspected. Then, the inspection result (such as whether or not the clamp is attached) is additionally written to the tag 30 as manufacturing history data on the manufacturing line.

  This wire harness 20 is conveyed to the next water stop production line with the tag 30 matched with it.

  First, the water stop production line sets the tag 30 on the reader / writer device 66 of the water stop production management device 60E. Then, the product number and manufacturing history data of the tag 30 are read, and it is checked whether or not the required manufacturing history corresponding to the product number is satisfied. After the manufacturing history is checked, when the water harness 20 is subjected to water stop processing, the manufacturing result (quality of the water stop operation or the like) is additionally written to the tag 30 as manufacturing history data in this line.

  The wire harness 20 subjected to the water stop treatment in this way is conveyed to the next whole inspection line together with the tag 30 associated therewith.

  In the overall inspection line, the entire manufacturing history data of the tag 30 is read, and a database in which the manufacturing number assigned to each wire harness 20 is associated with the manufacturing history data is created and updated. Thereafter, inspection management of the wire harness 20 is performed based on the database.

  In this product management system, when considering the part assembly process and the assembly process, the temporary assembly part A production line, the temporary connection part B production line, and the torque tightening part C production line for carrying out the part assembly process Corresponds to the first production line, the continuity inspection device 50, the torque tightening device 70, the input unit 64 and the like in those lines correspond to the first production line device, and the temporary connection part A production management device 60, The torque tightening part C production management device 60C and the like correspond to the first production management device. Further, a collective assembly production line for performing the collective assembly process corresponds to the second production line, and the collective assembly production management device 60D corresponds to the second production management device.

  According to the product management manufacturing system, the product management manufacturing method, and the manufacturing management apparatus configured as described above, the temporary connection part A manufacturing line, the temporary connection part B manufacturing line, and the torque tightening part C, which are upstream manufacturing lines. Manufacturing history data in the production line is stored in the tag 30, and the temporary connection part A, temporary connection part B, and torque tightening part C, which are parts in the upstream production line, are downstream production lines together with the respective tags 30. It is transported to the assembly line. Then, in the assembly / assembly manufacturing line, the assembly / assembly manufacturing management device 60D collates the manufacturing history data and the necessary manufacturing history data in the upstream manufacturing line to determine whether or not the parts are acceptable. For this reason, if there is a manufacturing history deficiency or the like due to a process skip or defective product mixing in the upstream production line, it is determined that the part has been rejected, and the process skip or defective product mixing can be more reliably eliminated. . Further, since the manufacturing history data is stored in the tag 30, the manufacturing history can be easily managed using the tag 30.

  Further, the assembly / manufacturing management device 60D collects the manufacturing history data of each tag 30 associated with each upstream component into one tag 30 and merges them. When manufacturing a product, each manufacturing history data can be easily collected and managed in one tag 30.

  In particular, in each component stage, which is a higher-level process than the assembly and assembly production line, each tag 30 is physically associated with each component, and therefore a unique identification number (serial number) or the like is assigned to each component. Each history can be managed, and further, the history of each part can be managed as a database by associating with the manufacturing number at the stage of assigning the manufacturing number to the wire harness 20 that is a collective product. There is also an advantage of being able to.

  Moreover, since the manufacturing history data is written in the tag 30 based on the processing status (for example, torque value, amount of water-stopping agent) of the manufacturing processing apparatus, the inspection result, and the output result from the input unit 64, various manufacturing processes are performed. History data can be accumulated.

  In particular, by storing the processing status (for example, torque value, amount of water-stopping agent) of the manufacturing / processing device, not only the presence / absence of a defect, but also the operation status (for example, torque or supplied water-stopping agent) of the manufacturing / processing device. It is also possible to grasp the situation where the amount is a phenomenon tendency) and to refer to a prior failure prediction.

  In addition, in this product management system, when considering the assembly and assembly process and the water stop production management device 60E as a reference, it can be understood as follows. That is, a collective assembly production line for performing the collective assembly process corresponds to the first production line, the clamp mounting inspection device 80 and the input unit 64 in this line correspond to the first production line device, and collective assembly production. The management device 60D corresponds to the first manufacturing management device. Moreover, the water stop production line for implementing a water stop process corresponds to a 2nd production line, and the water stop production management apparatus 60E corresponds to a 2nd production management apparatus.

  In addition, although the said embodiment demonstrated the case where a wire harness was manufactured, it is not restricted to this, It can apply about all the products manufactured through a some manufacturing line.

  Further, the manufacturing history data is not limited to the above example, but can include manufacturing status output from various manufacturing processing apparatuses, manufacturing status and inspection information based on inspection result output from inspection apparatuses using various sensors. . In addition to this, it is also possible to accept the contents of the manufacturing process by manual labor and the inspection result of the worker by visual inspection or the like through the input unit, and include the contents in the manufacturing history data. Further, at least one of these pieces of information may be included as manufacturing history data. Further, as the tag 30 used in the above embodiment, a member that can repeatedly write and erase data, more preferably, a member that can repeatedly print and erase can be recycled, which contributes to resource saving. be able to.

  In the present embodiment, the example in which the components A, B, and C and the wire harness 20 and the tag 30 are issued in a one-to-one correspondence has been described. One type of component (or product) of B, C and wire harness 20 and tag 30 may be issued in association with each other in a one-to-one relationship. As a more specific example, one tag 30 may be issued in association with a plurality of parts A. In this case, manufacturing history data is stored for each tag 30 in a group unit including a plurality of parts A associated therewith, and the manufacturing history is checked and managed in the group unit.
