Abstract

There is disclosed a wiring harness assembly line wherein a member supply line (2) including a looped track (20) and hangers (30) movably suspended from the track (20) is provided on the outer periphery of a plate supply line (1) so that the hangers (30) pass through a work space of an operator at an assembly position, whereby the member supply line is adapted to replenish a plate for wiring with members such as sub-assemblies.

Claims

1. A wiring harness assembly line comprising at least one plate adapted to receive a plurality of members which constitute a wiring harness, said plate moving in a plate direction in a closed plate path past at least one operator, a supply line, carrying said members in a downstream direction along a track forming a closed supply path, said supply line extending between a supply station, where said members are placed on said track, to a discharge station, where said operator removes said members from said supply line for inclusion in said wire harness on said plate, said discharge station being between said operator and said plate path, a plurality of hangers on said supply line, each of said hangers carrying one of said plurality of elements, said hangers being coupled to each other to form a plurality of groups of said hangers.

2. The assembly line of claim 1 wherein said discharge station is above said operator.

3. The assembly line of claim 1 wherein said supply line comprises a driver to move said supply line in said downstream direction along said track.

4. The assembly line of claim 1 wherein said supply line comprises a plurality of rings, depending from carriages in said track, a plurality of hangers, each said hanger comprising a coupling rod linked to two successive said rings, at least one suspension element, attached to and depending from said coupling rod, said suspension element adapted to releasably retain at least one said member.

5. The assembly line of claim 4 wherein a first said coupling rod extends between a first upstream ring and an adjacent first downstream ring, a second coupling rod extends between a second upstream ring and an adjacent second downstream ring, said first downstream ring being spaced apart from said second upstream ring in said downstream direction, and linked thereto.

6. The assembly line of claim 4 wherein there are two suspension elements on each said coupling rod spaced apart in said downstream direction.

8. The assembly line of claim 6 wherein each of said suspension element comprises a vertical depending rod having a supporting portion adjacent its distal end, said supporting portion extending in a perpendicular direction to said downstream direction.

9. The assembly line of claim 6 wherein a receiving unit is suspended from two adjacent said suspension elements, said unit adapted to receive at least one of said members.

7. The assembly line of claim 21 wherein said suspension element comprises a vertical depending rod having a supporting portion adjacent its distal end, said supporting portion extending in a perpendicular direction to said downstream direction.

10. The assembly line of claim 18 wherein said unit is a basket.

11. The assembly line of claim 18 wherein said unit is an open grating.
