Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a winding machine, and particularly to a winding form rotation prevention device for a winding machine.

[Conventional technology]

Conventionally, a winding machine in which a winding form support shaft is rotatably installed at the flyer's rotating axis and supports the winding form in a cantilevered manner has been designed to prevent rotation of the winding machine, as seen in Japanese Patent Publication No. 59-32888. A mechanism is adopted in which the winding form is clamped by a winding prevention member at a position where it does not interfere with the winding, and the winding is directly stopped from rotating. This is done by a mechanism that transmits the locking force of the mold.

[Problem that the invention seeks to solve]

The former has a detent member that clamps the winding form, so it is limited to stator cores with thin laminated layers and a small inner diameter. It is difficult to prevent rotation of a long winding form of a member, and the latter complicates the mechanism, increases the weight of the fryer rotating shaft, reduces responsiveness to acceleration/deceleration of the fryer rotation speed, and increases the required motor capacity. There are other problems.

[Means for solving problems]

SUMMARY OF THE INVENTION An object of the present invention is to provide an apparatus which eliminates the above-mentioned conventional drawbacks, prevents rotation of a winding form support shaft in a non-contact manner, and allows smooth supply of wire.

Therefore, in the present invention, a winding support shaft inserted through a fryer rotating hollow shaft is fixed with a detent core having a magnetic pole protruding from the opposite end of the fryer, and a field stator is arranged around the outer periphery of the core via an air gap. be.

〔Example〕

In the illustrated embodiment, reference numeral 1 denotes a frame on which a coil insertion jig 2 is fixed on a flat surface, a box 3 is provided on a side surface, a hollow shaft 8 is attached to the box 3, and a hollow shaft 8 is attached to the housings 4 and 5 via bearings 6 and 7. To support.
A drive pulley 9 is fitted onto one end of the hollow shaft 8 to constitute a fryer rotating shaft.
A winding form support shaft 14 is inserted and supported by bearings 12 and 13 at the axial center of the hollow shaft 8 to which a fryer 11 having a wire guide reel 10 is fixed.
Winding forms 16 and 17 are installed via winding form mounting fittings 15 fixed to the lower ends thereof. The winding forms 16 and 17 have a two-part structure, and a pair constitutes one winding form. Further, a detent core 18 is fixed to the other end of the winding form support shaft 14, and field stators 20 and 21 fixed to the box 3 with an air gap 19 on the outer periphery thereof are provided. In the figure, 22 is a guide, 23 is a stripper shaft, 24 is a coil stripper, 25 is a field stand, 26 and 27 are covers, 28 is a guide stand, 29 is its guide, 30 and 31 are magnetic poles, and 32
indicates a wire passage hole, and W indicates an electric wire.

[Effect]

The electric wire W supplied to the fryer 11 is connected to the guide 2
9 through the air gap 19 and the hollow shaft 8
Wire rod passage hole 32 penetrating from to fryer 11
The wire is guided to the wire guide reel 10 through. The electric wire W is wound around the outer periphery of the winding forms 16 and 17 as the fryer 11 rotates. In this way, the predetermined tension applied to the electric wire is generated on the winding form support shaft 14 as rotational torque of the winding form support shaft, and this torque is restrained by the magnetic attraction force of the magnetic poles installed in the detent core and the field stator. , which stops the winding form from rotating.

〔Effect of the invention〕

According to the present invention, the rotation of the winding form support shaft can be stopped in a non-contact state, and the conventional drawbacks are solved.
In addition, the wire rod is supplied smoothly, and the performance of the winding machine is improved.

Claims (1)

[Claims] 1. A winding form support shaft that is prevented from rotating is rotatably installed around the flyer's rotation axis, and a coil is formed by winding the wire around the outer circumferential surface of the winding form with the flyer rotating around the winding form fixed to the support shaft. In a type of winding machine in which the coil wound around the outer circumferential surface of a winding form is taken out using a coil stripper, a winding form support shaft inserted through a flyer rotating hollow shaft is protruded from the opposite end of the flyer to form a detent core with a magnetic pole. is fixed to the core, and a field stator is arranged around the outer periphery of the core via an air gap.
