Description

[Detailed description of the invention] (Industrial application field) The present invention is a component of a twisting device of a winding machine,
More specifically, in a twisting device that uses an automatic winding machine to wind the ends of a winding wire multiple times and twists them by rotating one end or one point in the center, one end of the ring around which the ends of the winding wire are wound is attached to a fixed body. Or it relates to a wire hook for a winding twist device for locking to a rotating body.

(Prior Art) An automatic winding machine is known in which a bobbin is fixed to a spindle, the spindle is rotated at high speed, and a wire is supplied while a wire supply nozzle is moved to perform winding.

FIG. 9 is a diagram for explaining an example of winding of an automatic winding machine and winding of the ends of the winding.

For winding, fix the bobbin 1 to the spindle 4,
This is carried out by moving the wire supply nozzle 2 in the direction indicated by arrow p in the figure while rotating the spindle 4 at high speed.

To wind the wire, stop the spindle 4 at a position where the terminal pin 1a of the bobbin 1 is parallel to the wire supply nozzle 2, and rotate the wire supply nozzle 2 in the direction indicated by the arrow r in FIG. 9b. This is done by

In such automatic winding machines, the end of the winding was twisted using only one wire, so that sufficient strength could not be obtained. For this reason, the winding portion was sometimes broken during the winding work or when the wound coil was used. In addition, if a single wire was used, there was a possibility that the electrical connection would become uncertain.

To solve this problem, a twisting device for twisting the winding ends has been proposed.

FIGS. 2 to 6 are explanatory diagrams showing the operation of an example of the twisting device.

As shown in Figure 2, the winding 3 is connected to the tension device 2.
After tension is applied by the tension pulley 23a of No. 3, the rotary tube 6 passes through the nozzle 21a of the wire guide 21 via the pulley 22 and has the wire hook 6.
1 and is guided to the winding machine.

The wire hook 6 is for twisting the wire rod 3, and the wire guide 21 is moved between the twist locking pin 5 and the wire hook 6 as shown in FIGS. 3 and 4. After multiple winding, the rotating cylinder 61
By rotating the strands, they are twisted together as shown in FIG. As shown in FIG. 6, the twisted wire rods are moved by retracting the movable part 51a of the air cylinder 51, retracting the twisting locking pin 5, and then feeding the wire rods 3 in the direction of the arrow. Remove it from the machine and move towards the winding machine.

(Problem to be solved by the invention) At the end of the part twisted together by the above-mentioned twisting device, there is always a loop where the claw passes through the locking part.
This ring should be as small as possible. If this ring is large, when the coil is finished winding, this part will come out on the top layer and may press against other parts of the winding, causing a shortcut. Also,
When passing a twisted wire through a nozzle, the ring on the side that enters the nozzle hole first may hit the entrance surface of the nozzle hole and break.

However, conventional wire hooks not only require troublesome processing in manufacturing, but also have the problem that it is difficult to make the ring at the twisting and locking end sufficiently small.

FIG. 10 shows an example of a conventional line hook.

As shown in FIGS. 10a and 10c, a hard rod-shaped pin 31 for locking the winding is mounted on a triangular pin support plate 32.
The pin support plate 32 is fixed to the claw fixing portion 30a of the line hook main body 30 by brazing.

In order to fix the pin 31 to the pin support plate 32 in a correct posture, the pin support plate 32 is provided with a V-shaped groove as shown in an enlarged view in FIG. 10b. As described above, there is a problem in that complicated processing is required and it is difficult to perform brazing accurately, and furthermore, if the thickness of the pin 31 is made too thin, the pin 31 may be damaged during brazing. There will be more. Therefore, since the pins 31 cannot be made very thin, there is a drawback that the twisted ends also become large.

The purpose of the present invention is to eliminate these drawbacks, do not require complicated processing, and furthermore, when windings are twisted together, the ring formed at the locked twisted end can be made much smaller than before. An object of the present invention is to provide a wire hook for a winding twisting device.

(Means for Solving the Problems) In order to solve the above-mentioned problems, the wire hanging device of the winding twisting device according to the present invention twists the winding ends of the winding wire material 3 by winding them multiple times and burning them together. As a component constituting the device, there is at least an L-shaped part for temporarily locking one end of the wound ring, and an elastic hard member with one side of the L-shape serving as a locking part for the winding wire material. Line hook 11 made of wire material
In order to support one side of the L-shape of the line hook 11,
A claw support metal fitting 12 made of another wire material having at least a V-shaped portion, and one side of the L-shape and the bent portion of the V-shaped portion intersect and contact each other inside the bent portion, and the mutual positions are not the same. The structure has a claw fixing part 10a for assembling the line hanging claw 11 and the claw support fitting 12 with screws so that they can be adjusted.

According to the above structure, the object of the present invention can be completely achieved.

(Example) Hereinafter, an example of the wire hanging tool of the winding twisting device will be described in more detail with reference to the drawings and the like.

FIG. 1 is a plan view, a front view, and a right side view showing an embodiment of the present invention.

As shown in FIG. 1, the claw fixing part 10 forming the main body of the line hanging tool is cylindrical, and is provided with a claw fixing part 10a having a partially extended shape. The nail fixing part 10a has two screw holes, and screws 15 and 16 are used to tighten the holding plate 13 for fixing the line hook 11 and the holding plate 14 for fixing the claw support fitting 12, respectively. It's getting old. The wire hooking claw 11 that locks the winding wire material 3 is made of a thin elastic hard wire material and is L-shaped.The short side of the L-shape is inserted between the holding plate 13 and the claw fixing part 10a, and the screw 15 is inserted. Tighten and fix it to the claw fixing part 10a. A V-shaped groove 10b is provided at the tip of the claw fixing portion 10a so that the long side of the L-shape of the line hanging claw 11 faces in the correct direction.

The claw support metal fitting 12 is made of a wire rod that is thicker than the wire hook 11 and easier to work with, and is formed into a V-shape in part. Both ends of the V-shape are bent into two stages, the parallel ends are inserted between the presser plate 14 and the claw fixing part 10a, and the screws 16 are tightened to fix it to the claw fixing part 10a. At this time, line hook 1
The line hanging claw 11 and the claw support metal fitting 12 are each assembled to the claw fixing part 10a so that the claws 1 and 1 intersect inside the V-shaped bent portion of the claw support metal fitting 12. When the claw support fitting 12 is assembled, recesses 10c, 1 are formed in the portion where both side surfaces of the claw fixing part 10a intersect with the claw support fitting 12 so that the claw support fitting 12 is fixed at a position within a certain range.
0c, the claw support metal fitting 12 can be moved along the longitudinal direction of the claw fixing portion 10a and fixed at an appropriate position within the range limited by the recess.

By adjusting the fixing position of the claw support fitting 12 in this way, the position where the long side of the L-shape of the line hanging claw 11 hits the bent part of the V-shaped portion of the claw support fitting 12 changes, and the inclination thereof is changed. be able to.

The more the long side of the L-shaped wire hook 11 is inclined, the shorter the part protruding from the V-shaped bent part becomes, and after twisting, the winding is sent out to the winding machine. At this time, there is less resistance when the annular part of the twisted end comes off the wire hook 11. In addition, as shown in FIG. 8, when the annular portion of the twisted end is about to come off the wire hook 11 (in the state shown in FIG. 8 a), the elasticity of the wire hook 11 causes it to lie further in the direction. Turn to Figure 8b
It also has the characteristic that it comes off more easily. This has the effect of eliminating problems in making the wire hook 11 thinner and the annular portion at the twisted end smaller.

In addition, the wire hanging tool of this example is similar to the conventional one shown in FIG.
It can be used in place of the line hook 6 shown in FIG. 6, and can be used in the same manner as described in the prior art described above. In Figures 2 to 6, the windings are twisted together by rotating the wire hook 6, but as shown in Figure 7, the wire hook 6 is fixed and the multiple winding loops are twisted together. By inserting the tip 7a of the rotating claw 7 into the center and rotating the rotating claw 7 in the direction of the arrow in the figure around the wound wire, twists in different directions can be applied to the left and right sides of the rotating claw 7. can. Further, in order to remove the twisting locking pin 5 shown in FIGS. 2 to 7 from the twisting end, the locking pin 5 is pulled in with the air cylinder 51 by pulling its movable part 51a.
In this case, the locking pin 5 can be removed by tilting the tip of the locking pin 5 in the direction in which the winding is sent out.

(Effects of the invention) As explained in detail above, according to the invention,
The wire hanging tool used in the winding twisting device consists of an L-shaped wire hook made of thin elastic hard wire, a hook support metal fitting having a V-shaped part that supports the wire hook, and an L-shaped wire hook of the wire hook. One side of the shape is in contact with and supported inside the V-shaped bent part of the claw support metal fitting.
In addition, by using a screw-fastening structure that allows the position of the claw support metal fittings to be adjusted with respect to the wire hanging claws, the structure is much easier to process than conventional ones, and the annular part formed at the end of the twisted wires has been made easier than before. This has the effect of making it much smaller.

Therefore, when manufacturing a coil using windings twisted together by the twisting device using the present embodiment, there is an effect that wire breakage during manufacturing or wire breakage during use of the coil can be prevented.
