Abstract

A wire body winding device that winds a wire body around a bobbin includes a bobbin pivoting mechanism that pivotally supports and pivots the bobbin, a wire body holding mechanism that holds the wire body, and a wire body moving mechanism configured to move the wire body holding mechanism. When the wire body is pulled out, the wire body moving mechanism moves the wire body holding mechanism between a take-up position where the wire body holding mechanism is capable of holding the wire body and a wire body winding position where the wire body is woundable around the bobbin.

First claim

The invention claimed is:

1. A wire body winding device that winds a wire body around a bobbin, the wire body winding device comprising:
a bobbin pivoting mechanism comprising a rotation shaft that pivotally supports and pivots the bobbin;
a wire body holding mechanism that holds the wire body by suction or by pinching; and
a wire body moving mechanism configured to move the wire body holding mechanism,
wherein a plurality of the bobbin pivoting mechanisms are provided, and
wherein the wire body moving mechanism:
is moved in a horizontal direction, and between the plurality of the bobbin pivoting mechanisms in a vertical direction; and
when the wire body is pulled out, moves the wire body holding mechanism between a take-up position where the wire body holding mechanism is capable of holding the wire body and a wire body winding position where the wire body is windable around the bobbin.

2. The wire body winding device according to claim 1 ,
wherein each of the bobbin pivoting mechanisms includes a rotation shaft that is inserted into one end side of the bobbin to drive the bobbin, a motor that rotates the rotation shaft, and a support shaft that is inserted into the other end side of the bobbin to support the bobbin.

3. The wire body winding device according to claim 1 ,
wherein the bobbin comprises a plurality of bobbins,
the bobbin has a wire body catching portion comprising a claw that locks the wire body,
the wire body winding device further comprises:
a bobbin selection mechanism comprising a slider configured to select the bobbin around which the wire body is wound; and
a wire body cleaving mechanism comprising a cutter configured to cleave the wire body locked to the bobbin.

4. The wire body winding device according to claim 1 ,
wherein the wire body holding mechanism is at least one of a suction nozzle configured to suction the wire body or a pinch roller configured to pinch the wire body.

5. The wire body winding device according to claim 1 ,
wherein a moving speed of the wire body holding mechanism is slower than a wire body pulling out speed of the wire body.

6. A wire body winding method using a wire body winding device, the wire body winding device including a plurality of bobbin pivoting mechanisms comprising a rotation shaft that pivotally support and pivot a bobbin around which a wire body is to be wound, a wire body holding mechanism that holds the wire body by suction or by pinching, a wire body moving mechanism configured to move the wire body holding mechanism, a bobbin selection mechanism comprising a slider configured to select the bobbin around which the wire body is to be wound, and a wire body cleaving mechanism comprising a cutter configured to cleave the wire body, the wire body winding method comprising:
holding the wire body by the wire body holding mechanism when the wire body is pulled out;
moving the wire body holding mechanism in a horizontal direction, and between the plurality of the bobbin pivoting mechanisms in a vertical direction, to a wire body winding position where the wire body is windable around the bobbin after the holding;
selecting the bobbin around which the wire body is to be wound by the bobbin selection mechanism after the moving;
locking the wire body by a wire body catching portion comprising a claw after the setting; and
cleaving the wire body locked to the bobbin by the wire body cleaving mechanism after the locking.
