Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a coil winding machine in which a coil lead-out section for winding a coil is configured to rotate around the outer periphery of a member to be wound to perform winding work.

A coil winding machine that winds a coil by rotating a coil lead-out part around the outer periphery of a member to be wound generally has a coil lead-out part formed in a flyer that is rotationally driven by an electric motor, etc. The winding work is performed by rotating the inner and outer circumferences of the slotted portion of the iron core. (In this case, an annular winding is applied to each slot.) By the way, in this type of conventional method, if the lead-out part of the coil and the member to be wound are separated, the coil will vibrate and the amplitude will be reduced. Because of the large size, it is difficult to wind the wire uniformly, and it is also extremely difficult to wind the wire in a narrow place, such as in a slot of a motor core.

For this reason, in the past, a nozzle was formed to protrude radially inward from the coil lead-out part, and the coil led out from the coil lead-out part was configured to be further drawn out through the nozzle to the vicinity of the wound part. Ta.

Such a conventional example will be explained based on FIGS. 1 and 2.

FIG. 1 is a partial vertical cross-sectional view showing the structure of a conventional coil winding machine in an easy-to-understand manner, and FIG. 2 is an enlarged view of the main part of the winding portion.

In the figure, 1 is a fryer configured to rotate around the outer periphery of the wire-wound member 2, 3 is an electric motor that is a power source for rotationally driving the fryer 1, and 4 is a partially hollow space formed integrally with the fryer 1. shaped arm, 5
is the winding coil 6 from the arm 4 of the fryer 1.
A coil lead-out portion 7 is a nozzle for guiding the coil 6 drawn out from the coil lead-out portion 5 to the vicinity of the wire-wound member 2 .

According to such a coil winding machine, since the coil 6 is pulled out through the nozzle 7 to the vicinity of the member 2 to be wound, the coil 6 related to the winding work is
Although the vibration of the fryer 1 can be suppressed to a very low level, the rotation speed of the fryer 1 cannot be increased too much because the rotation of the fryer 1 becomes unbalanced due to the nozzle 7 extending radially inward of the fryer 1. First, it had the problem of being unsuitable for high-speed winding due to its structure.

In addition, since the tip 7a of the nozzle 7 and the coil 6 pulled out from there are heavily rubbed, the tip 7a of the nozzle 7 may be worn out, or the coil 6 may be worn out.
The problem was that they were easily damaged.

The present invention has been made in view of the above circumstances, and includes forming a coil lead-out portion on a ring-shaped disc that rotates around the outer periphery of a wire-wound member, and also provides a gap on the coil lead-out side of the disc. This design focuses on providing ring-shaped guide discs facing each other through the coil lead-out portion, and drawing out the coil led out from the coil lead-out portion to the vicinity of the wire-wound member through the gap between both discs.

The present invention will be explained below based on an embodiment shown in the drawings. Note that the same parts in the figures are given the same symbols.

Fig. 3 is a diagram showing the main structure of the coil winding machine according to the present invention, Fig. 4 is a partial vertical sectional view thereof, and Fig. 5 is a diagram clearly showing the winding operation by rotating the flyer. .

In the figure, 1 is a fryer configured to rotate around the outer circumference of a wire-wound member 2, 3 is an electric motor that is a power source for rotationally driving the fryer 1, and 4 is a part formed integrally with the fryer 1. It is a hollow arm.

Reference numeral 11 designates a ring-shaped disc that is provided to connect and reinforce the inner peripheral sides of the arms 4, 4 of the fryer 1 and rotates around the outer periphery of the wire-wound member. Coil lead-out portion 1 communicated with
2 is formed.

Reference numeral 13 denotes a ring-shaped guide disk provided opposite to the coil lead-out side of the disk 11 with a gap 14 in between, and the coil 6 led out from the coil lead-out portion 12.
The wire is drawn out through the gap 14 into the vicinity of the wire-wound member 2.

Further, the wire-wound member 2 is arranged so as to be inserted through the ring portions of both discs 11 and 13, and is configured to be moved in the insertion direction, that is, in a direction perpendicular to rotation, to change the wire-wound position. There is.

According to the above configuration, after the coil 6 is led out from the coil lead-out part 12, the gap 1 between the disks 11 and 13 is
4 to the vicinity of the wire-wound member 2, vibrations in the direction perpendicular to the rotation can be suppressed to an extremely low level, making it possible to uniformly wind the wire at a predetermined position.

In addition, the disks 11 and 13 are provided facing each other in a sandwich-like configuration, and since there is nothing that rubs against each other in the direction of rotation of the coil 6, there is no risk of damaging the coil 6, and there are no wear parts such as in conventional nozzles. This makes operation and management extremely easy.

Furthermore, since the guide for guiding the coil 6 to the vicinity of the wire-wound member 2 is formed in the gap 14 between the two concentrically arranged discs 11 and 13, the rotational balance of the fryer 1 is good. , it is possible to significantly improve the winding speed due to high-speed rotation.

On the other hand, when the arm 4 is formed integrally with the fryer 1 as in this embodiment, the disc 1
1, the reinforcing effect against the centrifugal force between the arms 4, 4 becomes extremely large.

Then, by rotating the fryer 1 to move the coil lead-out part 12 around the outer periphery of the wire-wound member 2, and moving the wire-wound member 2 in a direction perpendicular to the rotational direction of the fryer 1, the disk 11,
The coil 6 is wound around the member 2 to be wound at the ring portion 13, and a winding operation is performed.

Further, the coil winding machine of the present invention is disclosed in Japanese Patent Application No. 55-70185 or Japanese Patent Application No. 56-7278 filed by the applicant of the present invention.
It is also extremely suitable for winding work as shown in No.

As explained above, according to the present invention, it is possible to obtain a coil winding machine that can perform winding work quickly and reliably.
