  FIG. 2 is a diagram schematically illustrating a schematic configuration of the support system 1 according to the present embodiment. FIG. 3 is a functional block diagram of the support system 1.

  When the management device 10 of the support system 1 conducts an appearance inspection, it codes a barcode of a predetermined management label 91 (indicated as “in-process kanban” in the drawing) associated with the wire harness 99 to be inspected. Read with the reader 50 to obtain the product number and the like.

  When the wire harness 99 is manufactured and the appearance inspection process is completed, and the wire harness 99 is accommodated in a predetermined accommodation means for sending it to the next process, the worker can support the wire harness 99 appropriately. It is.

  A polytenor shelf 80 is disposed at a place where the appearance inspection process is performed. The polytenor shelf 80 is provided with first to third polyteners 81 to 83 corresponding to a plurality of types of product numbers, here three product numbers. The wire harness 99 for which the appearance inspection has been completed is accommodated in a corresponding polytenor (any one of the first to third polytainers 81 to 83) for each product number. Usually, an operator takes out an appropriate polytenor, stores the wire harness 99, and returns it to its original location.

  The part number of the wire harness 99 to be accommodated is shown at the place where the first to third polytainers 81 to 83 are accommodated. Furthermore, the 1st-3rd LED71-73 which has a switch function is attached to each place. When the operator presses the completion button on the management device 10 at the end of the inspection of the wire harness 99, since the product number and the like can be grasped, the LED corresponding to the wire harness 99 (any one of the first to third LEDs 71 to 73) Lights up and guides the worker to an appropriate polytainer. In FIG. 2, since the second LED 72 is lit, the worker accommodates the wire harness 99 in the second polytenor 82.

The function of the support system 1 will be specifically described with reference to FIG.
The support system 1 includes a management device 10, first to third LEDs 71 to 73 attached to a polythener shelf 80, a PLC (Programmable Logic Controller) 60, and a code reader 50. The PLC 60 may be configured integrally with the management apparatus 10. Note that here, mainly the function of guiding the wire harness 99 to a desired polytenor after completion of the inspection is shown, and explanations of other functions are omitted as appropriate.

  The PLC 60 is a relay control device that operates the first to third LEDs 71 to 73. The code reader 50 reads the code (here, a bar code) of the management label 91 of the wire harness 99.

  The management apparatus 10 is composed of, for example, a PC and an installed application. Specifically, the management apparatus 10 includes a main control unit 12, a display unit 14, an SP (speaker) 16, a user interface 18, and an inspection management unit 20.

  The main control unit 12 comprehensively controls each component of the management device 10. The display unit 14 is an LCD display device, for example. The user interface 18 is input means such as a keyboard and a mouse.

  The inspection management unit 20 has a function of performing inspection registration of the wire harness 99. Specifically, the examination management unit 20 includes an examination registration unit 22, a data holding unit 24, and a guidance control unit 26.

  The inspection registration unit 22 is connected to the code reader 50 and reads the code of the management label 91 of the wire harness 99 via the code reader 50. Thereby, the management apparatus 10 can grasp | ascertain the product number etc. of the wire harness 99 used as a test object.

  In addition, the inspection registration unit 22 displays the inspection status or the like on the display unit 14 or displays a completion button or the like at the end of the inspection, and acquires the user's press via the user interface 18. When the inspection completion button is pressed, the guidance control unit 26 is notified, and the first to third LEDs 71 to 73 corresponding to the corresponding product numbers are turned on. Further, when the first to third LEDs 71 to 73 are pressed, the lighting is extinguished and the inspection registration unit 22 detects it, and the management apparatus 10 does not proceed to the next process unless the lights are turned off.

  Further, the inspection registration unit 22 clearly indicates the corresponding first to third polyteners 81 to 83 together with the photograph of the polytenor shelf 80 on the display unit 14 or sends a voice notification from the SP 16 to guide the worker.

  The data holding unit 24 stores the inspection result in a predetermined format. The data holding unit 24 may be provided in an external server.

  When the inspection registration unit 22 obtains the completion of inspection from the operator, the guidance control unit 26 controls the PLC 60 to turn on the first to third LEDs 71 to 73 that have received instructions from the inspection registration unit 22.

  FIG. 4 is a diagram illustrating an example of a guidance screen displayed on the display unit 14 of the management apparatus 10. At the top of the screen, the product part number, the inspector, etc. are displayed. The inspection number is displayed below it. Further, the number of inspections, the number of acceptable products, the number of unacceptable materials, etc. are displayed on the left side in the middle wide area. On the right side, the first to third polyteners 81 to 83 of the polytenor shelf 80 are squared. The product part number is shown in an easy-to-understand manner. The operator can definitely accommodate the wire harness 99 in an appropriate place by checking this screen and visually recognizing the first to third LEDs 71 to 73 that are actually lit.

FIG. 5 is a flowchart showing a procedure during an appearance inspection.
When starting the inspection, the operator reads the name using the code reader 50 (S10). Here, the inspection registration unit 22 of the management device 10 reads the code of the management label 91 of the wire harness 99 via the code reader 50.

  Subsequently, the worker performs an appearance inspection of the wire harness 99 (S12). In the appearance inspection, the worker inputs necessary items in the inspection registration unit 22 as necessary. If it is determined that reworking is necessary, the wire harness 99 is sent to the reworking process. When the appearance inspection is completed without any defects in the wire harness 99 (S14), the operator presses the completion button (or confirmation button) displayed on the display unit 14 of the management apparatus 10 (S16).

  When the pressing of the completion button is detected, the examination registration unit 22 notifies the guidance control unit 26 and turns on the desired first to third LEDs 71 to 73 (S18).

  An operator confirms whether the 1st-3rd polytainer 81-83 exists in the lighting location of 1st-3rd LED71-73 (S20). If not, the polytenor should be placed at hand, so the wire harness 99 (inspected part) is put into the polytenor (S22).

  If there is a polytainer at the lit place, if there is another polytenor at the operator's hand (next to the inspection table), the polytenor is temporarily returned to the polytenor shelf 80 (S24). Then, the worker takes out the corresponding polytenor (first to third polytainers 81 to 83) that is lit from the polytenor shelf 80, places it next to the inspection table (S26), and stores the wire harness 99 therein. (S22).

  After that, when the number has been reached and the shipping label has been issued (Y in S28), the shipping label is attached to the wire harness 99 and sent to the next process (shipping process or the like), and the inspection process is completed. In addition, since it will be conveyed for every polytenor in the next process when the accommodation number is reached, there will be no mistake in quantity. When the number has not been reached and the shipping label has not been issued (N in S28), the process returns to S10 and the next wire harness 99 is inspected.

  Conventionally, after a shipment label is attached, a packing inspection, a storage number inspection, and a mixed product mixing check are performed, and finally shipping processing is performed. However, in the present embodiment, since it is possible to eliminate mixing of foreign products in the inspection process, the quantity has been substantially confirmed at the inspection stage. Therefore, after the inspection process, it is not necessary to perform the accommodation number inspection and the check for mixing different types, so that the work efficiency can be improved and the work quality can be appropriately secured.

  The present invention has been described based on the embodiments. This embodiment is an exemplification, and it is understood by those skilled in the art that various modifications can be made to each of those components and combinations thereof, and such modifications are also within the scope of the present invention.

  FIG. 6 is a diagram schematically illustrating a schematic configuration of the support system 101 according to the modification. Here, differences from the above-described embodiment will be described. In this support system 101, instead of the first to third LEDs 71 to 73, first to third fences 174 to 176 are attached to the openings of the respective stages of the polytenor shelf 80. The 1st-3rd fences 174-176 are opened and closed by the 1st-3rd solenoids 171-173 provided corresponding to each. That is, the first to third fences 174 to 176 are configured to open instead of lighting the first to third LEDs 71 to 73. Moreover, the interruption | blocking sensor etc. are provided instead of the switch function of 1st-3rd LED71-73, and the test | inspection registration part 22 can detect an appropriate accommodation state. By setting it as such a structure, the selection mistake of the 1st-3rd polytainers 81-83 can be avoided more effectively.

  In addition, the support systems 1 and 101 are not only applied to the inspection process before shipment, but also can be applied when the wire harness 99 is transported from one process to the next process in a production line, for example. .
