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 displaying a wire laying image showing plural electric wires constituting the wire harness in the laid state;
a wire transfer robot travelling along one long side of the display unit to convey an electric wire, and
a wire cutting machine for cutting the electric wire conveyed by the wire transfer robot at a cutting position,
wherein the display unit includes a screen on which a worker can carry out tasks, and
wherein the one long side of the display unit is a travelling area of the wire transfer robot, wherein another long side of the display unit is a working area of the worker.

2. The wire harness manufacturing system, according to claim 1 , wherein the display unit comprises a rectangular shape.

3. The wire harness manufacturing system, according to claim 1 , wherein the display unit comprises plural displays arranged along a longitudinal direction of a wire harness to be manufactured.

4. The wire harness manufacturing system, according to claim 1 , wherein an entire length of the wire harness is displayed by plural displays of the display unit.

5. The wire harness manufacturing system, according to claim 1 , wherein the wire laying image to be displayed on the display unit includes divided images to be displayed on respective displays.

6. The wire harness manufacturing system, according to claim 1 , wherein the display unit is supported such that the screen is substantially level on which the worker can carry out tasks.

7. A wire harness manufacturing system, comprising:
a rectangular display unit comprising plural displays arranged along a longitudinal direction of a wire harness to be manufactured and displaying a wire laying image showing plural electric wires constituting the wire harness in the laid state, an entire length of the wire harness being displayed by plural displays of the display unit, the wire laying image to be displayed on the display unit including divided images to be displayed on respective displays;
a wire transfer robot travelling along one long side of the display unit to convey an electric wire, and
a wire cutting machine for cutting the electric wire conveyed by the wire transfer robot at a cutting position,
wherein the display unit includes a screen that is substantially level on which a worker can carry out tasks, and
wherein the one long side of the display unit is a travelling area of the wire transfer robot, wherein another long side of the display unit is a working area of the worker.

8. The wire harness manufacturing system according to claim 7 , wherein the travelling area of the wire transfer robot is above the screen of the display unit.

9. The wire harness manufacturing system according to claim 8 ,
wherein the wire cutting machine includes a measurement unit which measures a fed length of the electric wire, and
wherein when the sum of a measured length L 2 of the electric wire measured by the measurement unit and a length L 3 of the electric wire from the cutting position to a gripping portion of the wire transfer robot reaches a cutting length L 1 , wherein L 1 , the wire transfer robot is stopped from travelling, and the wire cutting machine cuts the electric wire at the cutting position.
