Wire laying-out apparatus

A wire laying-out apparatus, comprising:

• a wire laying-out head for laying out electric wires on a wire laying-out plate for manufacturing a wiring harness,
• wherein the wire laying-out head includes:
• a base,
• a plurality of wire guiding means which are arranged in a linear manner with respect to the base for guiding an electric wire to be laid out, wherein different electric wires are fed to the respective wire guiding means, and
• selecting means, which is movable back and forth in a linear manner parallel to a direction in which the wire guiding means are arranged, such that the single selecting means selects a wire guiding means at a position corresponding to a position wherein the selecting means is stopped, to bring the selected wire guiding means into an activated state;
• Y-direction moving means connected to the base for moving the base in a predetermined Y direction, such that the base crosses the wire laying-out plate parallel to a surface of the wire laying-out plate;
• X-direction moving means connected to the Y-direction moving means for moving the Y-direction moving means in a X direction parallel to the surface of the wire laying-out plate and orthogonal to the Y direction,
• wherein the base includes a support frame which extends in the Y direction and has a predetermined height in a Z direction orthogonal to the X direction and the Y direction,
• wherein the plurality of wire guiding means are arranged in the Y direction of the support frame, and each of the plurality of wire guiding means respectively includes a wire guide hole extending in the Z direction for guiding an electric wire in the Z direction, wherein the wire guiding means are respectively held movably up and down in the Z direction by the support frame, wherein the plurality of wire guiding means respectively include change means which is switchable between a pass state where an electric wire can pass through the respective wire guide hole and a stop state where an electric wire cannot pass through the respective wire guide hole, wherein the plurality of wire guiding means further respectively include tension applying means for applying tension to electric wires which pass through the wire guide holes,
• wherein the selecting means lowers the selected wire guiding means in the Z direction, wherein the selecting means brings the change means in the wire guiding means lowered in the Z direction into the pass state, and wherein the selecting means activates the tension applying means of the wire guiding means lowered in the Z direction;
• and
• an arch obliquely inclined and provided above the support frame, wherein a plurality of guide rollers for guiding electric wires to be fed to the respective wire guiding means are disposed in the arch.
