[0006]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, according to the present invention, an electric wire supporting jig is erected on an assembling work table, and the electric wire supporting jig holds a group of electric wires constituting a wire harness. In a wire harness manufacturing apparatus that lays wires along a required path and then winds and bundles a group of wires after wiring, the above-mentioned assembly work table is removed by removing a long section where no wire support jig is erected. Then, the both sides of the section are divided and formed, and the divided assembly worktables can be moved from a regular position spaced apart by a dimension corresponding to the removal section to a close position from the regular position. An assembly work table moving means for moving the divided assembly work table to a close position when laying the wire group, hanging down and laying the wire group in the removal section, and dividing the wire group when winding the tape. Move platform to proper position Allowed to provide an apparatus for manufacturing a wire harness is configured to extend the wire group.

The section to be removed is a section in which the trunk line of the electric wire group is laid in a straight line for 2 m to 10 m. Make up.

As the means for moving and stopping the divided assembly work table, conventionally known means can be appropriately employed. For example, while mounting the rails on the lower surface of the divided assembly work table, these rails are slidably fitted to guide rails fixed below, and the rails are moved to the lower guide rails at the regular position and the proximity movement position. A stopper is provided to stop the operation.

As described above, when the section where the wire group is laid in a straight line is long, if the section is removed and the wire group is hung downward, the worker does not need to reciprocate in the long section, and The burden on members can be reduced. This is particularly effective when the number of electric wire groups to be repeatedly wired is large. When the assembling workbench is moved to the normal position after the completion of the wiring, the group of electric wires hanging downward is extended linearly, so that the tape winding operation can be performed easily and accurately.

[0010]

Embodiments of the present invention will be described below with reference to the drawings.

The conventional assembling worktable 1 shown in FIG. 4 is constituted by divided assembling worktables 10 and 11 on both sides by removing the distance L between the main line supporting jigs 2F and 2G in FIG. The removed section L is a section in which the jig is not erected and the wire group is laid in a straight line. The removal section L is a section of 2 m to 10 m.

The above-mentioned split assembling work table 10 has a conventional FIG.
Similarly, the jigs 2A and 2D for supporting the terminals of the electric wires that connect the connectors A and D to the terminals or the terminals of the electric wires that are connected later to the connectors A and D are erected in the same manner as in the related art, and the trunk line support jig is used. The tool 2F is erected. Further, a wire support jig 2H is newly set up near the divided end 10a.

The other divided assembly work table 11 is also the same, and similarly to the conventional FIG. 4, a group of wires connecting the connectors B, C and E to the terminals or a group of wires connecting the connectors B, C and E later. The jigs 2B, 2C, and 2E for supporting the terminal are provided upright as in the conventional art, and the trunk support jig 2G is provided upright. Further, an electric wire support jig 2I is newly erected near the divided end 11a.

As shown in FIGS. 3A and 3B, rails 13, 1
4 is installed. On the other hand, a guide rail 15 protrudes from a base 20 below the assembly work table, and
14 is slidably fitted on a guide rail 15 so that an operator can move by pressing the divided assembly work tables 10 and 11. In addition, it is good also as a structure which moves the division | segmentation work tables 10 and 11 by drive means, such as a motor.

On the guide rail 15, stoppers 16A and 16B for stopping the rails 13 and 14 at regular positions are protruded at both ends, while the rail 1 is located at a position close to the intermediate portion.
Stoppers 17A and 17B for stopping the positions 3 and 14 are protrudingly provided.

In the present embodiment, the outer end of the rail 13 abuts against the stopper 16A and stops.
When the outer end of the rail 14 comes into contact with the outer end of the rail 6B and stops, the dimension (shown in FIG. 2) of the removal section L between the split ends of the split assembling worktables 10 and 11 is set to be a regular dimension of 10 m. I have. Further, the inner end of the rail 13 abuts against the stopper 17A and stops.
When the inner end of No. 4 comes into contact and stops and comes to the close position, the dimension L ′ between the split ends of the split assembling work tables 10 and 11 is 50 cm.
It is set to become.

In the apparatus having the above-described structure, when manufacturing the wire harness, first, as shown in FIG.
0 cm. In this state, the wire bundle W that has been temporarily bound is wired along each predetermined path while being supported by the jigs 2A to 2I.

At this time, the main line portion which is originally laid in a straight line is the removal section L 'of the divided assembling work tables 10 and 11 on both sides.
Then, it is hung downward in a U-shape while being held by the jigs 2H and 2I on both sides. As described above, since the wiring section of 10 m can be reduced to 50 cm, the worker does not need to repeatedly reciprocate the wiring section of 10 m to perform wiring.

After completing the wiring of all the electric wire groups, the divided assembling worktables 10 and 11 at the close positions are moved to the guide rails 15.
To return to the normal position. In this state, the distance between the divided ends of the divided assembling worktables 10 and 11 becomes a regular size of 10 m, and the wire group hanging downward extends linearly.

Thereafter, the tape is wound around the wire group W to perform the final binding. At the time of this tape winding operation, since the wire group W can be performed in a straightened state, the tape winding operation can be easily and accurately performed.

[0021]

As is apparent from the above description, according to the present invention, the wire harness assembling work table is divided by removing a long span section for linearly laying the electric wire group, and the divided assembly is performed. Since the work table is positioned close to the wiring line, a long span can be reduced. In this shortened section, the wires are hung down and wired, so there is no need for the operator to repeatedly go back and forth over long spans, thus greatly reducing the burden on the worker and improving work efficiency. Can be.

Further, after the wiring is completed, the divided assembly work table is moved away from the base and returned to the normal size, so that the tape group can be wound in a state where the wire group is extended linearly. Therefore, the tape winding operation can be easily and accurately performed without lowering the efficiency of the tape winding operation.
