JPS6347275A - Winder for toroidal coil - Google Patents

Abstract

PURPOSE:To perform the stable winding on a toroidal core by providing an arm section rotating around the tip of a clip section. CONSTITUTION:A core 1 is pinched by a clip 18b, then winding is performed once. Next, a switch is turned on to drive a motor 12. The driving force of the motor 12 rotates a shaft 9 via a belt 19. An arm section 15 and a desk 10 are rotated by the rotation of the shaft 9. When the desk 10 is rotated and a photo-interrupter 11a senses a slit 8, the motor 12 is stopped. The rotation of the arm section 15 is stopped by the rotation stop of the motor 12, then the toroidal core 1 is wound. Accordingly, the toroidal core is wound once, then the switch is turned on, and after the toroidal core is confirmed to have been rotated to the next winding position, winding is performed again.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a winding machine for a toroidal coil that winds a wire around an annular toroidal core.

[Prior Art] Fig. 4 is a perspective view showing a conventional toroidal coil winding machine holding an annular toroidal core.
A core holder 2 for holding a toroidal core 1 is attached to a base 4 via a rod 3. The core holder 2 is made of a cushioning material such as urethane rubber and is rotatably attached to the rod 3.

When winding with this winding machine, three core holders 2
The toroidal core 1 is held between the toroidal cores 1 and 1, and the wires are wound while rotating the core in the horizontal direction.

[Problems to be Solved by the Invention] However, in the conventional holding method, when the diameter of the two-ring toroidal core 1 is less than 10flII11 and the thickness is less than a mathematical value, as the core 1 is wound horizontally,
The core holder 2 cannot press the core 1 evenly, and the core 1 falls off from the core holder 2. Therefore, an object of the present invention is to provide a stable winding machine for toroidal cores.

[Means for Solving the Problems] The present invention includes a clip portion that clamps a toroidal core, an arm portion that rotates around the tip of the clip portion, and a drive portion that rotationally drives the arm portion.

[Function] When winding the core using a toroidal coil winding machine configured as described above, the toroidal core l is held between the clips 18b and the motor 12 is driven, thereby rotating the arm part. Wind the wire while rotating it around the tip of the clip.

[Example] An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows an embodiment of the present invention, in which a stand 6 is attached to the end face of the base 5 so as to stand perpendicularly to the base 5. As shown in FIG. An upper plate 7 extending in a direction opposite to the base 5 is attached to the upper surface of the stand 6. Upper pre desk 10. Support metal fittings 11
A photointerrupter 11a (light sensor) and a motor 12 are provided, which are attached to the edge of the disc-shaped desk 10 via b'. The shaft 9 attached to the center of the desk 10 passes through the upper plate 7 and has a bearing 13.
and the supporter 1 of the arm portion 15 through the pulley 14.
Connected to one end of 6. The motor 12 is attached to the pulley 14.
A belt 19 is attached to transmit the power from.

On the other hand, the arm portion 15 is connected to the supporter 16 and the desk 1.
Supporter 15 on the opposite side connected to shaft 9 extending from 0
The shaft 17 is attached to the other end of the desk 10 and extends on the opposite side of the shaft 9 extending from the desk 10, and the clip portion 18 is attached to the shaft 17. This clip portion 18 consists of a clip holder 18a connected to the shaft 17 and a clip 18b that holds the toroidal core from above and below.

First, as shown in FIG. 2, the toroidal core 1 is held between the clips 18b. After the core 1 is held between the clips 18b, winding is performed again. Next, step on a foot switch (not shown) to turn on the switch and drive the motor 12. The driving force of the motor 12 is transmitted through the belt 19 and rotates the shaft 9. The arm part 15 and the desk 1 are rotated by 90 rotations of the axis.
0 rotates. The desk 10 rotates and the photo interrupter
When 11a senses the slit 8, the motor 12 is stopped. By stopping the rotation of the motor 12.

When the arm portion 15 stops rotating, the toroidal core 1 is again wound.

After winding the wire around the toroidal core in this way, press the foot switch to complete the next winding. Since the toroidal core is characterized by having an arm part that rotates around the tip of the part and a drive part that rotationally drives the arm part, it is possible to securely hold the toroidal core with the clip and wind the core.
