Abstract

A wire harness manufacturing system includes a display unit, a wire cutting machine that draws an electric wire from a wire feed reel and cuts the electric wire to a predetermined length, a control unit that directs the display unit to display a wire laying image and wire work identification information for identifying a work regarding each electric wire, the wire laying image including a plurality of wire images showing the plurality of electric wire in the laid state and the wire work identification information being displayed in the vicinity of the corresponding wire image, and a memory unit that stores the wire laying image and work instruction information so as to correspond to the wire work identification information, the work instruction information including cut length of the electric wire. The control unit sends the cut length information to the wire cutting machine.

First claim

What is claimed is:

1. A wire harness manufacturing system, comprising:
a display unit;
a wire cutting machine that draws an electric wire from a wire feed reel and cuts the electric wire to a predetermined length;
a control unit that directs the display unit to display a wire laying image and wire work identification information for identifying a work regarding each of a plurality of electric wires, the wire laying image including a plurality of wire images showing the plurality of electric wires in the laid state and the wire work identification information being displayed in the vicinity of the corresponding wire image; and
a memory unit that stores the wire laying image and work instruction information so as to correspond to the wire work identification information, the work instruction information including cut length of the electric wire,
wherein the control unit acquires the cut length information corresponding to the wire work identification information from the memory unit when the wire work identification information displayed on the display unit is read by a reading machine and is received as a signal instructing to read the work instruction information including the cut length information, and sends the cut length information to the wire cutting machine so that the wire cutting machine cuts the electric wire to a length corresponding to the cut length corresponding to the wire work identification information.

2. The wire harness manufacturing system according to claim 1 , further comprising a travel unit that travels while gripping the electric wire drawn from the wire feed reel, wherein the travel unit travels a distance corresponding to the cut length in accordance with an instruction from the wire cutting machine or the control unit.

3. The wire harness manufacturing system according to claim 1 , wherein the work instruction information includes wire-end information indicating end-processing of the electric wire, and the control unit directs the display unit to display the wire-end information near an end portion of the wire image.

4. The wire harness manufacturing system according to claim 3 , wherein the wire work identification information and the wire-end information are stored, separately from the wire arrangement image, in the memory unit.
