Wire harness winding device

1. A wire harness winding device comprising:

a fixing member to which one ends of a plurality of wire harnesses are fixed; and

a winding member of a tubular shape which is formed coaxially with the fixing member, and is able to wind the plurality of wire harnesses on a circumferential surface thereof,

wherein the circumferential surface of the winding member is provided with a plurality of wire harness insertion portions at an interval in a circumferential direction,

wherein the plurality of wire harnesses are individually inserted with an excess length into the plurality of wire harness insertion portions, and other ends of the plurality of wire harnesses are led out to an outside of the winding member, and

wherein when the plurality of wire harnesses are at a first position of a winding position at which the plurality of wire harnesses are wound by the winding member and a leading position at which the plurality of wire harnesses are led from the winding member, a portion of the excess length is wound by the fixing member, and

when the plurality of wire harnesses are at a second position of the winding position and the leading position, the portion of the excess length is slacked between the fixing member and the winding member.

2. The wire harness winding device according to claim 1 , wherein when the plurality of wire harnesses move from the winding position to the leading position,

the winding member rotates in a direction opposite to a winding direction in which the portion of the excess length is wound by the fixing member, and

the portion of the excess length wound by the fixing member is slacked between the fixing member and the winding member.

3. The wire harness winding device according to claim 1 , wherein when the plurality of wire harnesses move from the winding position to the leading position,

the winding member rotates in a direction identical to a winding direction in which the portion of the excess length is wound by the fixing member, and

the portion of the excess length slacked between the fixing member and the winding member is wound by the fixing member.

4. The wire harness winding device according to claim 1 , further comprising a housing portion of a cylindrical shape which is vertically provided opposing to the circumferential surface and in which the plurality of wire harnesses is housed between the circumferential surface of the winding member and the housing portion,

wherein the housing portion is provided at an interval from the wire harnesses wound in a slack state at an outermost side of the winding member when approximately half of lengths of the plurality of wire harnesses are wound by the winding member.

5. The wire harness winding device according to claim 1 , wherein the plurality of wire harnesses are formed in a belt shape.

6. The wire harness winding device according to claim 1 , wherein

a portion of each of the plurality of wire harnesses which is inserted in the wire harness insertion portion is folded back, and

the folded portion of each of the plurality of wire harnesses is movably provided in a circumferential direction of the circumferential surface.

7. The wire harness winding device according to claim 1 , wherein.

the plurality of wire harnesses are wired over a base and a slide structure which is slidably provided to the base, and

the winding member rotates in synchronization with a motion of a driving member which slidably drives the slide structure to lead or wind the plurality of wire harnesses.
