Detailed Description of the Invention

[0001]

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

[0002]

2. Description of the Related Art Conventionally, in the case of a coil in which winding and taping are alternately performed, a winding device and a taping device are arranged side by side, and a work (bobbin) whose winding is completed is automatically or manually sent to the taping device and repeated. The method is taken.

However, this requires a large installation space, and since the work is attached and detached for each work, the reliability is low. Therefore, there has been proposed a winding device that repeats winding and taping in one station.

This is a device in which a taping machine is provided on a support structure of a nozzle bar which is movable in X, Y and Z directions.
The work on the opposing spindle is wound and twisted by rotating the nozzle attached to the nozzle bar and the spindle, and the tape is attached to the work by the taping machine which is also movable in the X, Y and Z directions. Taping is performed in accordance with the rotation of the paper (Japanese Patent Laid-Open No. 63-63119).
-See the 280404 publication, etc.).

However, in such a winding device, since the taping machine is provided on the support structure of the nozzle bar and the winding position and the taping position are at the same position, there is a space in the space. No, it is difficult to handle. When changing specifications, work such as wire replacement is difficult due to the taping machine.

Further, since the taping machine does not have a tape holding mechanism, there is a drawback that the position is not stable when the tape is attached to the work.

Further, since the taping machine is integrally attached to the base, the tape cannot be easily replaced. Therefore, when changing the specifications of the tape, the tape holder must be removed or the base must be replaced. I had to do it.

The present invention aims to solve such problems.

[0009]

According to the present invention, there is provided a spindle of a headstock on which a work is mounted, and a winding mechanism for winding a wire rod on the work of the spindle through a nozzle. A chuck that holds the tape from the tape holder on a carriage that can be moved forward and backward, left and right, and up and down independently of the spindle stock. Arrange the roller and tape cutter to stroke the tape.

[0010]

The spindle headstock, which is located on the winding mechanism side when the work is wound, is moved from the winding position to the taping position when taping.

Therefore, the taping machine can be arranged at a position distant from the winding mechanism side, so that the space is widened and the work such as wire replacement can be easily performed.
