Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a keeling device.
Conductive wire used in electrical coils, such as solenoids and relay coils, is usually strengthened in skeins, ie, by winding them in multiple layers and then twisting the skeins. This step is performed frequently, usually by hand, and is time-consuming, labor-intensive, unreliable, and expensive. Furthermore, the efficiency of the coil winding machine is reduced because the coil winding machine must be temporarily stopped during the process of skeining the conductor wire.

In accordance with the present invention, a shuttle member is provided with a wire guide which is constrained to reciprocate along a linear trajectory and through which the wire traverses between a supply reel and a coil winder. A wire guide on the shuttle member reciprocates across the linear trajectory, and a wire guide for locking the wire when the shuttle member reciprocates and winds the wire multiple times. The wire is moved on an annular track surrounding the holding members, and one of the wire holding members is configured to be rotatable so as to twist the multi-wound wire to form a skein. A skein device is provided that includes means for removal from a wire holding member.

In one embodiment, the shuttle member is preferably driven by a chain drive and preferably includes a plurality of wire guides so that a plurality of corresponding wires can be skeined simultaneously. The rotatable wire holding member has a hook shape, and the drive device that drives the hook is used for positioning to return the hook to its original position and correct its direction after the rotation of the hook is completed. Equipped with a motor.

The control mechanism also includes a proximity switch for stopping the chain drive as soon as the shuttle member completes multiple windings of the wire and simultaneously starting rotation of the rotatable wire holding member.

Another wire holding member consists of a retractable pin.

The invention will now be described in more detail with reference to the accompanying drawings, which show preferred embodiments of a keeling device according to the invention.

The attached drawings show a conductor storage reel (not shown) to be placed on the right side of the keeling device shown in FIGS. 1 and 2, and a coil winding wire (not shown) to be placed on the left side. A dual skeining device is shown for simultaneously skeining two wires in the process between.

During the actual winding of the coil, i.e. when no skein winding operation is being carried out, the wire is
It passes through the guide eye 2 provided on the shuttle member 3, which is stopped at this stage of the working process, and exits from the second ceramic guide 4 to reach the coil winding machine. The shuttle member 3 is a sliding member that moves between the rails 5,5. The sliding member is provided with a lever member having two eyes 2, and the lever member is connected to a link member 6 attached to a circulation chain 7 that circulates between two chain wheels 8, 9. There is. The chain wheel 8 is driven by a motor 10, and the chain wheel 9
is an idler. When the motor 10 operates, the shuttle member 3 moves back and forth on the rail 5, and the eye 2
each moves on a circular orbit. chain 7
is a marker member 12 that cooperates with the proximity switch 13;
When the proximity switch 13 is energized, the chain drive is stopped by the arrival of the marker member 12, and acts to stop the shuttle member at a predetermined position.

The two hollow rotating members 14 are each provided with a rearwardly bent pin 15, thereby forming a hook member on the trajectory followed by the wire as the eye 2 moves on the annular trajectory. The hook member or pin 15 thus locks the wire each time the shuttle member 3 reaches the end of the device. pin 15
On the opposite side of the hook member formed by
pins 17, 17 are provided. These pins 17, 17 normally protrude into the wire trajectory, and when the shuttle member 3 reciprocates, the wire is wound around the pins 15, 17, thereby performing multiple windings. . pin 17,
17 is attached to a plate 18 configured to pivot around an axis 19 under the action of a solenoid 20. Since the entire member with the pins 17, 17 can be adjusted in position in the longitudinal direction of the device, the length of the skein can be adjusted as required within the length of the annular track formed by the eye 2. You can change it accordingly. The pins 17, 17 project through the plate which serves to release the formed skein from the pins when they are retracted.

In order to give twist to the multi-wound wire, the rotating members 14, 14 are configured to be rotatable by a belt transmission means 21 driven by a motor 22 and a pulley 23, and the pulley 24 is configured to be rotatable by a belt transmission means 21 driven by a motor 22 and a pulley 23. It is set up for. motor 22
A positioning motor 25 is provided in combination. This positioning motor 25 has the same rotor as the motor 22, but when the stator is energized, it stops at a predetermined position, brings the pins 15, 15 to the final position shown in the figure, and then stops at that position. hand,
After retracting the pins 17, 17, the formed wind is drawn out through the hollow rotating member 14 and the eye 4 when the coil winding machine is started.

The operation of the apparatus of the present invention will be briefly described below. As previously mentioned, while the coil winder is in operation, the wire passes through the interior of the skein machine. That is, it enters through eye 1, passes through eye 2, and exits through hollow rotating member 14 and eye 4. When the coil is sufficiently wound, the coil winding machine stops, and the motor 10 drives the chain 7 to move the shuttle member 3 back and forth. The wire is wound between pins 15 and 17 a fixed number of turns, usually adjusted by a timer, and when the appropriate number of turns is completed,
When the proximity switch 13 is actuated and the marker 12 reaches the switch, the chain 17 is stopped and the shuttle member 3 is stopped approximately at the position shown.

Motor 22 is then started to give pin 15 a predetermined number of rotations to form a skein. After a predetermined number of rotations, the motor 22 is switched off and the positioning motor 25 is energized to correct the final position of the pins 15,15. Subsequently, the pins 17, 17 are pulled in by the solenoid 20, and the skein is pulled out when the coil winding machine is started, and the above cycle is repeated.

It should be noted that in order to strengthen the conductors of two consecutive coils, one skein can be formed and then cut.

Furthermore, when using two or more coil winding machines, a plurality of winding devices may be stacked as required.

Various other embodiments may be possible within the scope of the invention.
