DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a winding device.

[0002]

2. Description of the Related Art In general, a transformer or the like is manufactured by alternately performing winding and taping and winding in a multi-layer. In this case, a winding machine and a taping machine are alternately arranged on a conveyor, and a winding to a work is performed. And taping are sequentially performed.

[0003] However, this requires a winding machine and a taping machine corresponding to the number of layers, which is expensive and bulky. Therefore, a winding device that repeats winding and taping in one station has been proposed.

This is a device in which a taping device is provided on a support structure of a nozzle holder movable in X, Y, and Z directions.
The wire rod is wound and tied by the rotation of the nozzle and the spindle attached to the nozzle holder, and a tape is attached to the bobbin by a taping device that can be moved in the X, Y, and Z directions, and taping is performed with the rotation of the spindle. (See Japanese Patent Application Laid-Open No. 63-280404).

[0005]

Incidentally, in a transformer or the like, a wire having a different wire type and wire diameter may be wound in multiple layers on the same bobbin. Replacement equipment must be added.

However, in the above-described winding device, since the position of the spindle is fixed, the winding position and the taping position are at the same position, and the taping device is provided on the support structure of the nozzle holder. Therefore, even if the wire rod changing device is provided, the taping device hinders the replacement of the wire rod.

Further, in this case, since the wire replacement is performed at the same place in addition to the winding and taping, all the operations are performed in series, and there is a disadvantage that the operation becomes longer in terms of tact.

An object of the present invention is to solve such a problem.

[0009]

A winding device according to the present invention comprises:
A drive unit that rotates the spindle for mounting the work is provided,
A winding mechanism for winding a wire on a work through a plurality of standing winding nozzles and a taping device for taping the work at a position distant from the winding position are arranged with a drive unit interposed therebetween, and the spindle is mounted on the work. together with movably formed between the winding position and the taping position, the wire exchange <br/> winding mechanism provided automatic exchangeable wire changer to allow parallel with taping.

[0010]

When the workpiece is wound, the spindle is moved toward the winding mechanism, and when taping, the spindle is moved toward the taping device.

As a result, the winding position and the taping position are different from each other, so that the taping device can be separated from the winding side.
A wire replacement device can be provided to facilitate wire replacement.

Further, since the winding position and the taping position are different from each other, taping and wire exchange can be performed simultaneously, and the tact time can be reduced.
