Description

  The present invention relates to an assembling apparatus for assembling a wire harness for automobiles and the like, and more particularly, to a wire harness assembling apparatus for facilitating a routing operation when a plurality of branch lines branched from a trunk line or the like are densely packed. .

  Conventionally, when assembling a branch portion of a wire harness, as shown in FIG. 4, a plurality of branch lines branched from the main line by holding the main line portion of the wire harness W on the routing jig 2 erected on the assembly work table 1. A connector 5 connected to a terminal of Wa is hooked on a plurality of routing jigs (connector receiving jigs) 3 erected on the wire harness assembly work table 1 to form a branch of the wire harness W. Usually, the wiring jig 3 for receiving the connector is fixed with a bolt or the like at a position away from the branch point O by a predetermined distance.

  By the way, in recent years, due to an increase in electrical components for automobiles, the number of branch lines branching from the trunk line of the wire harness increases, and a lot of branch lines Wa branch from the same branch point O on the trunk line. Wa tends to be dense. Therefore, the routing jigs 3 holding a large number of branch lines Wa will be set up close to each other, and therefore the work space when routing each branch line Wa or winding the tape becomes narrow, There has been a problem that workability deteriorates.

  Therefore, as a wire harness assembling apparatus for solving this problem, as shown in FIG. 5, a rail 10 is provided on the work table 1 along an arc centering on the branch point O of the branch line Wa. A device is provided in which the lower end 12 of the routing jig 3 is movably engaged so that the routing jig 3 can be moved while maintaining a certain distance from the branch point O (for example, patents). Reference 1). Some of them provide grooves instead of the rails 10.

According to this assembling apparatus, the routing jig 3 can be moved while maintaining a certain distance from the branch point O while the branch line Wa is supported, so that the routing operation and the tape winding operation of the adjacent branch line Wa are performed. In this case, the work space can be expanded by appropriately moving the adjacent routing jig 3.
