[Detailed description of the invention]

0001

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

0002

[Prior Art] Generally, transformers and the like are manufactured by winding wires and taping them alternately and winding them in multiple layers. A method is used in which taping is performed sequentially.

[0003] However, this requires winding machines and taping machines for the number of layers, making it expensive and large. Therefore, a winding device has been proposed that repeatedly performs winding and taping at one station.

[0004] This is a device in which a taping device is provided on a support structure for a nozzle holder that is movable in the X, Y, and Z directions, and the taping device is attached to a workpiece (bobbin) on an opposing spindle.
The wire is wound and tied by the rotation of the nozzle and spindle attached to the nozzle holder, and the tape is applied to the bobbin by a taping device that can also move in the X, Y, and Z directions, and the taping is performed as the spindle rotates. (Refer to Japanese Patent Laid-Open No. 63-280404, etc.).

[0005]

[Problems to be Solved by the Invention] By the way, in transformers and the like, wire rods of different wire types and wire diameters are sometimes wound in multiple layers on the same bobbin. replacement equipment must be added.

However, in the above-mentioned 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 a wire changing device is provided, the taping device gets in the way and it is difficult to change the wire.

In addition, in this case, in addition to winding and taping, wire rod replacement is also performed at the same location, which has the disadvantage that all operations are performed in series, resulting in a longer takt time.

The present invention aims to solve these problems.

[0009]

[Means for Solving the Problems] A winding device of the present invention includes:
A drive unit is provided to rotate the spindle on which the work is mounted.
A winding mechanism that winds a wire on a workpiece through a winding nozzle and a taping device that tapes the workpiece are installed at a position away from the winding position, and the spindle is placed between the winding position of the workpiece and the taping position. The winding mechanism is formed to be movable, and is provided with a wire changing device that can automatically change the wire of the winding mechanism.

0010

[Operation] When winding a workpiece, the spindle is moved to the winding mechanism side, and when taping the workpiece, the spindle is moved to the taping device side.

[0011] Therefore, the winding position and the taping position are different from each other, and therefore the taping device can be separated from the winding side, so the taping device does not get in the way.
A wire replacement device is provided to facilitate wire replacement.

Furthermore, since the winding position and the taping position are different from each other, taping and wire replacement can be performed at the same time, and the takt time can be shortened.
