Abstract

PURPOSE:To stop the revolution of a coil former support shaft under a noncontacting state while also feeding a wire rod smoothly by projecting the coil former support shaft inserted into a flyer rotary hollow shaft from the reverse end of a flyer, fixing a detent core with a magnetic pole and arranging a field stator on the outer circumference of the detect core through an air gap. CONSTITUTION:An electric wire W fed to a flyer 11 enters a guide 29, and is introduced to a wire guide reel 10 through a wire-rod path hole 32 penetrated up to the flyer 11 from a hollow shaft 8 through an air gap 19. The electric wire W is wound on the outer circumferences of coil formers 16, 17 with the revolution of the flyer 11. Accordingly, predetermined tension applied to the electric wire is generated as the revolving torque of a coil former support shaft in the coil former support shaft 14, and the torque is constrained by the force of magnetic attraction of a detent core and a magnetic pole fitted to a field stator, thus stopping the rotation of a coil former.

Description

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

[Conventional technology]

Conventionally, the 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 a winding system as shown in Japanese Patent Publication No. 59-32ggg. Place the winding form W +g in a position that does not interfere with one revolution of the lyre.
Adopting a mechanism that directly prevents rotation by pinching with a non-slip member, and also special public service in the 1970s! As disclosed in Publication No. 2/2/, this is accomplished by a mechanism that transmits a force for preventing rotation of the winding form from the outside of the rotary shaft of the flyer.

[Problems that the invention aims to solve]

The first dish has a rotating part that hides the volume, so
It is limited to stator cores with a small Pg diameter and thin thickened coils, and it is difficult to stop the winding form 11 of a short coil and to stop the long winding form of a multi-stage coil, and the latter is difficult to prevent from rotating due to the mechanism. In addition, the weight of the fryer rotation shaft increases, the responsiveness to acceleration/deceleration of the fryer rotation speed decreases, and the required motor space becomes large.

[Means for solving problems]

SUMMARY OF THE INVENTION An object of the present invention is to provide an apparatus which eliminates the above-mentioned drawbacks of the conventional method, allows rotation of a winding form support shaft without contact, and allows smooth supply of wire.

Therefore, in the present invention, the winding form support shaft inserted into the fryer rotating hollow shaft is extended from the opposite end of the fryer, and a magnetic pole is provided.
It is fixed to a gl-stop core 1, and a field stator is arranged around the outer periphery of the core with an air gap interposed therebetween.

〔Example〕

In the illustrated embodiment (1), a coil insertion jig (2) is fixed to the flat part using a frame, a box (3) is provided to the side part,
A hollow shaft (8) is supported via a bearing 16) +7) on the hatching (4th eye 6) attached to the box (3). The dry gooley (9) is fitted onto one end of the middle nine shaft (8) to form the fryer rotation shaft, and the dry gooley (

The said hollow shaft (8) that fixes the υ is carefully bearing α2
ml inserts and supports the winding form support shaft α, and installs the winding form α11 (Lη) through the winding form mounting bracket (Is) fixed to its lower end.The winding form aG ar has a two-part structure with seven Configure the @ type.

Further, a rotary core 〇Fj is fixed to the other end of the winding form support shaft α4, and a field stator 121) fixed to the box (3) is provided with an air gap alY on its outer periphery.

[year/month]

Electricity supplied to the flyer αυ! ! (4) enters from the guide 4, passes through the air gap 0, passes through the wire passage hole (to) from the hollow shaft (8) to the flyer αυ, and leads to the wire guide reel (1 (1). As the flyer αυ rotates, the winding form Wrap the wire around the outer circumference of the frame.

In this way, the predetermined tension exerted on the electric wire is generated on the winding form support shaft α4 as rotational torque of the winding form support shaft, and this torque is rotated to rotate the magnetic poles a of the magnetic poles installed in the city core and field stator.
It is restrained by kA suction force and can be pulled out around the winding form.

〔Effect of the invention〕

According to the present invention, the rotation vt of the frame support shaft can be adjusted in a non-contact state, and the drawbacks of the conventional method are eliminated.

In addition, the wire rod is supplied smoothly, and the performance of the winding machine is improved.
