Abstract

A twisted wire manufacturing method for manufacturing a twisted wire, includes hanging U-turn portions of the at least two wires on a wire hanging member, checking one end portions and the other end portions of the at least two wires, pulling up the at least two wires in a state that the U-turn portions are hung on the wire hanging member, twisting the at least two wires together after the wire pull-up step is conducted, and transferring a twist-completed wire produced by the wire twisting step to a twisted wire temporary placement hook which is disposed above the wire hanging member.

Claims

1. A twisted wire manufacturing method for manufacturing a twisted wire by twisting at least two wires together, the method comprising:

a wire middle portion hanging step of hanging U-turn portions of the at least two wires on a wire hanging member, the U-turn portions being positioned at a middle portion of the at least two wires;

a wire end portions chucking step of chucking one end portions and the other end portions of the at least two wires;

a wire pull-up step of moving the wire hanging member upward and away from the one end portions and the other end portions to pull up the at least two wires in a state that the U-turn portions are hung on the wire hanging member after the wire end portions chucking step is conducted;

a wire twisting step of twisting the at least two wires together after the wire pull-up step is conducted; and

a twisted wire discharging step of transferring a twist-completed wire produced by the wire twisting step to a twisted wire temporary placement hook which is disposed above the wire hanging member.

2. The twisted wire manufacturing method according to claim 1, wherein the wire hanging member is formed in a circular roller, a recess being formed over a full circumference of the circular roller for hanging the U-turn portions are hung;

and

wherein in the wire pull-up step, the U-turn portions being hung on the recess of the circular roller are pressed by a wire pressing member.

4. The twisted wire manufacturing method according to claim 1, further comprising:

a same direction rotating step of rotating one end portions and the other end portions of the at least two wires in the same rotation direction.

5. The twisted wire manufacturing method according to claim 1, wherein a transfer hook is mounted on a rotary shaft extending perpendicular to the upward direction.

3. A twisted wire manufacturing method for manufacturing a twisted wire by twisting at least two wires together, the method comprising:

a wire middle portion hanging step of hanging U-turn portions of the at least two wires on a wire hanging member, the U-turn portions being positioned at a middle portion of the at least two wires;

a wire end portions chucking step of chucking one end portions and the other end portions of the at least two wires;

a wire pull-up step of pulling up the at least two wires in a state that the U-turn portions are hung on the wire hanging member;

a wire twisting step of twisting the at least two wires together after the wire pull-up step is conducted; and

a twisted wire discharging step of transferring a twist-completed wire produced by the wire twisting step to a twisted wire temporary placement hook which is disposed above the wire hanging member,

wherein in the wire pull-up step, the U-turn portions being hung on the wire hanging member are separated into a prescribed wire arrangement by a separating plate.
