[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a coil winding machine for manufacturing a coil such as a deflection yoke coil, and more particularly to a winding clip delivery device interposed between a wire and a coil.

[0002]

2. Description of the Related Art A conventional coil winding machine grips a wire with a stepped tip, and in this state, a spindle flange rotates together with the tip to wind up a coil. After winding,
Once the grip by the tip is released, the wire and the coil are gripped again, and the gap between the tip and the coil is cut with a cutter. Thereafter, the coil is dropped downward, and the spindle flange is rotated again to wind the next coil.

[0003]

The conventional coil winding machine described above has the following disadvantages. That is, according to this coil winding machine, a mark gripped by the stepped chip is formed at the end of the wound coil, and the mark becomes a hook-like portion and accompanies the coil. Since this hook is completely unnecessary as a coil, it is cut off in a separate step.Before reaching this cutting step, the hook does not come off from the winding machine or get stuck between the coils. Sometimes you have to rely on manual labor to understand. Since the winding process of the coil is automated, the prior art has a disadvantage that the hook-shaped portion formed on the coil requires manual labor to increase the cost and increase the cost.

Further, in the winding machine, in the step of setting the wire material to the winding portion, that is, in the step of transferring, there is only one clip for performing the transfer. Therefore, only one chip constituting a part of the clip is provided. There is only. In order to wind a coil, one end of the wire is gripped and wound, so after winding one coil, the wire portion once gripped must be wound in order to wind the next coil. Release it and re-hold the wire at the end of the coil. This operation process for regripping is a useless process, and reduces the production efficiency. Furthermore, when the wire is bent again, the wire may be bent, which may cause the winding machine to run idle due to failure to hold the wire.In recent years, the number of wires wound at the same time has increased. Accidents due to damage tend to occur frequently. In view of the above-mentioned drawbacks of the prior art, the present invention provides two sets of clips each having a set of tips for gripping a wire and a cutter for cutting the wire, without regripping the wire, and An object of the present invention is to provide a winding clip delivery device of a coil winding machine capable of manufacturing a coil having no hook portion.

[0005]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a disk-shaped face plate attached to a shaft of a driving base, and a first clip receiving member provided on an end face of the face plate. And a second clip receiver, a first clip and a second clip attached to the drive base, and when coupled to one of the first clip receiver and the second clip receiver or the first clip and the second clip, the other And two sets of moving clips that separate from
A first cutter attached to the first clip and a second cutter
A second cutter attached to a clip; and a mold guide for coil winding fixed to the face plate, wherein the moving clip grips a wire at the end of coil winding, and Two winding cutters separate the coil from the two sets of moving clips, and the driving base moves in the axial direction of the shaft to retract the mold guide from the coil.

Further, a first notch is formed near the first clip receiving portion on the peripheral portion of the disc-shaped face plate, and a second notch is formed near the second clip receiving portion. The moving clip connected to the second clip grips the wire rod passing through the first notch, and the moving clip connected to the second clip receiver grips the wire rod at the coil winding end end passing through the second notch. And a winding clip delivery device.

[0007]

The winding clip delivery device of the present invention grips one end of a wire and winds it on a coil. After the winding is completed, the other end of the wire is gripped and both ends of the coil are gripped. The coil is energized and heated to melt the insulating enamel and solidify the coil. Thereafter, the wires at both ends of the coil are cut. For this reason, a linear wire remains at both ends of the coil, and a portion that is gripped and bent in a hook shape does not remain. Therefore, the coils are not entangled with each other at the hook-shaped bent portion, and the members are smoothly circulated. In addition, when the starting end of the coil is grasped, there is no need to grasp the coil again, so that there is no waste in the operation and quick processing can be performed in terms of time.

The coil 14 is held while being sandwiched between the guides 8 and 6, but is fixed to the female guide 6 by energizing and solidifying the coil 14 as described above. The coil 14 is released from the formation plate (not shown). Since the guides 8 and 6 are separated from each other, the coil 14 loses its holding and falls downward as shown in FIG. 9, and is carried by a carry-out conveyor (not shown). Alternatively, the coil 14 can be
To move to a predetermined position. Then, the drive base 1
Operates in the direction opposite to arrow F and returns to the position shown in FIG. Then, the holder cylinders 17, 17 are operated to release the engagement of the hooks 16a, 16a from the grooves 18a, 18a of the moving clips 18, 18, respectively. Next, the first and second clip cylinders 9a and 20a are retracted to
The second clips 11 and 21 are separated from the moving clips 18 and 18. As shown in FIG. 7, when the coil 14 is wound and then separated from the wire 5, the end of the wire 5 is gripped by the moving clip 18 and thereafter moves from the state of FIG. 9 to the state of FIG. 1. I did not release the grip. Therefore, the above-mentioned winding is started again from the preparation state of FIG.

[0019]

As described above, according to the present invention, in the clip delivery device of the coil winding machine, the first clip and the second clip are provided.
Since two clips including a clip are provided, and each of the two clips has a cutter and a moving clip, a coil made of a straight wire without hooks can be obtained. That is, the wire on the coil winding start side and the end on the end side are gripped with a chip, and the wire between the gripped portion and the coil is cut. At the end of the wire, only the straight portion of the wire is left, and the hook-shaped bent portion due to gripping is cut off and does not remain on the coil side. Therefore, according to the present invention, since a coil having no hook-shaped bent portion is obtained as described above, the coil is not massed or caught during transfer by a conveyor, and the coil is automatically mass-produced. Thus, accidents such as no coil supply are prevented, and smooth coil supply is performed.

Further, according to the present invention, since the first and second clips grip the both ends of the coil at the end of the winding as described above, the next coil is wound after the end of the winding. In this case, a step of re-gripping the wire is not required, and the time can be significantly reduced. That is, when the wound coil is cut, it is already ready to start winding, so there is no need to perform a special preparation operation, and there is no wasted time, so that the working cost is reduced.

Further, according to the present invention, two sets of moving clips are provided, and the two sets of moving clips are moved and connected between the first and second clips. Because the wire is delivered in the form,
Troubles that easily occur at the time of delivery do not occur. As described above, according to the present invention, coil winding can be performed in a short time without causing an accident or the like, and therefore, a high quality and low cost coil can be provided.
