  The present invention relates to a method for manufacturing a wire harness and a manufacturing support device, and more particularly, to a method for manufacturing a wire harness for a vehicle and a manufacturing support device that implements the method.

  In the manufacture of wire harnesses mounted on automobiles and the like, a manufacturing apparatus is often used which erections a plurality of assembly jigs along the wiring pattern on an assembly drawing board. A manufacturing method is performed in which the electric wires are arranged in a predetermined order while being supported by a corresponding jig on the assembly drawing board, and are bundled after the arrangement of all electric wires.

  Further, in the manufacture of a wire harness having a large number of wires mounted on an automobile or the like, not only is the wire entangled easily, but the length and length of each wire can be excessive or insufficient depending on the position and orientation of each wire in the wire bundle. Therefore, the assembly work is not easy and it takes time to learn the work. In view of this, a manufacturing method and a manufacturing support apparatus that reduce the work load during the assembly work have been proposed.

  For example, when manufacturing a wire harness having a large number of electric wires, there is a manufacturing method in which a plurality of sub-harnesses are produced by temporarily binding a plurality of electric wires into semi-finished products (intermediate assemblies) and combining the sub-harnesses. (For example, refer to Patent Document 1).

  In addition, as a manufacturing support device that makes it easy to visually grasp the final assembly shape when manufacturing a new wire harness, a temporary assembly model simulating the assembly shape of a wire harness is composed of a plurality of rod-shaped members and connecting members. There are known ones that are configured to be compatible with various assembly shapes of wire harnesses (see, for example, Patent Document 2).

A circuit 61, a sequence control circuit 62 for controlling the order of light emission driving of the plurality of sets of light emitting elements 56, 57, 58, 59, etc. by the switching circuit 61 in a predetermined sequence, and a switching command signal are supplied to the sequence control circuit 62 And a command switch 63.

  The predetermined order corresponds to a wiring work order set in advance for a plurality of sub-harnesses 31 used for manufacturing the wire harness W. For example, the sub-harness 31 is first subjected to wiring, and then the sub-harness. The order of wiring on the assembly drawing board 10 is fixed and set in a fixed order in advance such that 32 is a wiring target.

  The plurality of light emitting elements 56 are composed of, for example, single color light emitting diodes (LEDs) of the same color, and are easily visible to the worker who performs the wiring work on the holding members 53A, 53B, 53C, 53D and the like.

It has become. Further, when only one set of light emitting elements 56 corresponding to the wiring target sub-harness 31 is caused to emit light, the light emitting elements 57, 58, 59, etc. corresponding to other sub-harnesses that are not the wiring target are turned off. Yes.

  The order control circuit 62 corresponds to one set of light-emitting elements corresponding to each of the sub-harnesses to be wired among the plurality of sets of light-emitting elements 56, 57, 58, 59, etc. The switching circuit 61 controls the order of switching of the light emission drive system so that the switching circuit 61 switches to the pair of light emitting elements 57 corresponding to the sub-harness 32 in the predetermined order. It is a circuit to execute (sequential circuit).

  The order switching timing in the order control circuit 62 is determined in accordance with a command signal from the command switch 63. The logic of such order control and the hardware configuration of the control circuit itself are known, for example, a predetermined sequence. It may be the same as that of the CPU configuration that executes the program.

  The command switch 63 detects, for example, the operation input of the work completion button by the operator when the wiring work is completed, or the assembly board 10 is sequentially placed in the wiring work area such as each sub-harness 31 as a pallet on the line conveyor. When transported, it is configured to detect that the wiring work area is switched to the next area. However, the command switch 63 detects only the start of the entire wiring work of the wire harness W or the wiring work of each sub-harness, and thereafter, the command signal is output every time the preset work time of each wiring work is elapsed. A command signal circuit may be configured so that

  As described above, the switching circuit 61 and the order control circuit 62 of the partial illumination means 55 cooperate with the command switch 63 so that a part of the sub-harnesses to be wired out of the plurality of sub-harnesses 31 and the like are in a predetermined order. A plurality of sets of light emitting elements 56, 57, 58, 59, etc. are arranged in accordance with the operation of the switching circuit, and the wiring work of a part of the sub-harness to be wired is configured. It is a light output unit that presents visual indication information by executing selective partial illumination on the area.

  Next, the manufacturing method of the wire harness of this embodiment that can be suitably executed using the manufacturing support apparatus as described above will be described.

  First, in the preparation stage, a plurality of sub-harnesses 31 or the like in which any one of the attachments 35a to 35d (connection parts) corresponding to at least one electric wire is attached and temporarily bound, and a plurality of sub-harnesses 31 and the like A plurality of sets of assembly jigs 21 to 26 corresponding to the above are prepared, and the assembly drawing board 10 mounted along the predetermined wiring shape 11 is prepared.

  Specifically, partial illumination means 55 that presents visual instruction information on the assembly drawing board 10 by selective partial illumination with respect to a plurality of sets of assembly jigs 21 to 26, etc. is prepared, and in a predetermined order. According to the above, while some of the sub-harnesses, for example, the sub-harness 31 are to be wired, only a part of the assembling jigs 23 to 26 among the plural sets of assembling jigs 21 to 26 is partially illuminated. 55 so that partial illumination is possible.

  It should be noted that a plurality of monochromatic light emission type or multicolor light emission type light emitting elements 56 and the like that can be individually illuminated individually for a plurality of sets of assembly jigs 23 to 26 are prepared, and some sub-harnesses are arranged in a predetermined order. While 31 is an object to be wired, selective partial illumination with respect to some assembly jigs 23 to 26 that are wiring work target jigs is performed in a selective lighting order of the plurality of light emitting elements 56 and the like. It may also be possible to accompany a change in lighting state such as lighting color.

  Next, as described below, a plurality of sub-harnesses 31 and the like are wired on the assembly drawing board 10 in a predetermined order and finally bound to manufacture the wire harness W.

  When wiring a plurality of sub-harnesses 31 etc. on the assembly drawing board 10, on condition that some sub-harnesses of the plurality of sub-harnesses 31 etc. are to be wired according to a predetermined order, Among a plurality of sets of assembly jigs 21 to 26, etc., some of the sub-harnesses, for example, some assembly jigs 23-26 corresponding to the sub-harness 31 are replaced with a plurality of sets of assembly jigs 21-26, etc. Among them, visual instruction information for instructing visually so as to be visually distinguishable from other assembly jigs is presented to the operator.

  Specifically, for example, when the command switch 63 is first pressed after the power is turned on, a set of assembly jigs 21 to 26 corresponding to the sub-harness 31 to be wired first, particularly the holding Of the plurality of switches 61a, 61b, 61c, 61d, etc. of the switching circuit 61 by the order control circuit 62 so that the plurality of light emitting elements 56 mounted on the assembly jigs 23 to 26 for lighting are turned on. 61a is controlled to be in an on (closed) state, and the other switches 61b, 61c, 61d and the like are controlled to be in an off (open) state.

  At this time, only the plurality of light emitting elements 56 are lit on the assembly drawing board 10, and the assembly jigs 23 to 26 are partially illuminated so as to be visually distinguishable from the other assembly jigs. Visual instruction information indicating that the jig is a line work target jig is presented to an operator who stands by at a predetermined work position with respect to the assembly drawing board 10. Therefore, even if the number of the plurality of sub-harnesses 31 is large, the plurality of assembly jigs 23 to 26 that are the wiring target jigs in a predetermined order according to the visual instruction information presented by the plurality of light emitting elements 56. Can be easily identified while clearly distinguishing it from other assembly jigs located in the vicinity, and the sub-harness 31 to be wired can be easily and quickly identified. As a result, it is hard to be confused about which sub-harness is the next wiring target, and it is possible to clearly grasp the wiring work target area, and the workability of the wiring work is greatly improved, and the entanglement and attachment of wires Work mistakes such as erroneous insertion of the product into the jig can be reliably prevented.

  Next, when the wiring work of the sub-harness 31 is completed, a switching command signal is supplied from the command switch 63 to the order control circuit 62, for example, by an operation input of a work completion button by an operator.

  At this time, in the order control circuit 62, the light emission driving state of the set of light emitting elements 57 corresponding to the next sub harness 32 from the light emission driving state of the pair of light emitting elements 56 corresponding to the first sub harness 31 according to a predetermined order. The switching order of the switching circuit 61 is controlled so as to shift to step S4. Some of the switches 61a among the plurality of switches 61a, 61b, 61c, and 61d are turned on, and the other switches 61b, 61c, 61d, and the like are turned off. From the first partial lighting state, the switch 61b is turned on, and the other partial lighting states are switched to the other switches 61a, 61c, 61d and the like.

  That is, only the plurality of light emitting elements 57 are lit, and the assembly work jig corresponding to the sub-harness 32 among the assembly jigs 21 to 26 can be visually distinguished from other assembly jigs. By being partially illuminated, visual instruction information for instructing a jig for the next wiring work target is presented to the worker. Therefore, even if the number of the plurality of sub-harnesses 31 is large, the plurality of assembly jigs corresponding to the sub-harness 32 are replaced with other assembly jigs by the visual instruction information presented by the plurality of light-emitting elements 57. Can be clearly identified, the workability of the wiring work of the sub-harness 32 is significantly improved, and work mistakes are also prevented.

  Next, when a command for switching is supplied from the command switch 63 to the sequence control circuit 62 when the wiring work of the sub-harness 32 is completed, the light-emitting drive state of the pair of light-emitting elements 58 corresponding to the next sub-harness is further changed. The second part in which the switching order of the switching circuit 61 is controlled so as to shift, the switch 61b is turned on among the plurality of switches 61a, 61b, 61c, 61d, and the other switches 61a, 61c, 61d are turned off. From the illumination state, the switch 61c is turned on, and the third partial illumination state in which the other switches 61a, 61b, 61d and the like are turned off is switched.

  Therefore, as described above, the partial illumination on the next wiring target work jig significantly improves the workability of the next wiring target sub-harness, and prevents work mistakes.

  Hereinafter, in the same procedure, the order control is executed so that the partial illumination state for the wiring target work jig is switched in a predetermined order in response to the switching command signal input from the command switch 63 to the order control circuit 62. At the same time, the wiring work for the plurality of sub-harnesses 31 and the like is sequentially executed, and the necessary partial binding work is performed in a timely manner. The final main bundling is performed on the main line portion, and the wire harness W is completed.

  In addition, even if the next switching command signal is input from the command switch 63 to the sequence control circuit 62 for a certain period of time after the last sub-harness becomes the wiring target among the wiring work of all the sub-harnesses 31 and the like. The order control circuit 62 may wait without shifting to the next order control from the switch 61a, or may cause some or all of the light emitting elements 56 to blink.

  Thus, in the manufacturing method of the present embodiment, even if the number of the sub-harnesses 31 is large, the sub-harness to be wired according to a predetermined order is determined by the visual instruction information from the partial illumination unit 55. It can be easily specified without hesitation, and the work target jig among the many assembly jigs on the assembly drawing board 10 can be easily and accurately visually identified. As a result, the workability of the wiring work of the wire harness W combining the plurality of sub-harnesses 31 and the like is remarkably improved.

  Further, according to the manufacturing support apparatus of the present embodiment, even if the number of the sub-harnesses 31 is large, the wiring target according to the predetermined order can be easily visually confirmed by partial illumination on the assembly board 10. It can be quickly identified, and among the many assembly jigs 21 to 26 corresponding to the many sub-harnesses 31 etc., the wiring work target jig can be easily discriminated by visual inspection, and a similar jig nearby can be mistaken. Insertion can be surely prevented.

  In each of the above-described embodiments, the light emitting element 56 and the like constituting the partial illumination means 55 are directly attached to the plurality of assembly jigs 21 to 26 and the like that are erected on the assembly drawing board 10. However, the partial illumination means provided on the outside of the assembly drawing board 10 from the partial illumination means to the wiring target jig as a beam spot, and a part by light of a specific color corresponding to the wiring shape of the wiring target Illumination or the like may be performed. In that case, electrical wiring may not be provided on the assembly drawing board 10.

  The partial illumination means 55 switches the partial illumination state on the assembly board 10 in a predetermined order by the order control circuit 62 in response to a command signal from the command switch 63. Are sequentially conveyed to a plurality of wiring work areas corresponding to a plurality of sub-harnesses according to a predetermined order by the conveyor, and corresponding wiring work is performed in each wiring work area, each assembly drawing Each time the assembly drawing board 10 is transported from the preceding wiring work area to the next wiring work area so that the partial illumination state is switched in a predetermined order with respect to the board, a command is sent to the command switch 63. It is conceivable to make an operation input.
