Abstract

PURPOSE:To obtain the high twisting speed for a wire material and reduce noise by forming a supporting structure for supporting a twist pin to a form having the superior balance for the rotary shaft. CONSTITUTION:As twisting proceeds, a part wound in multiple turns is twisted and made short, and the position of a wire laying pin is shifted to a wire laying pin 11. At this time, also the position of a twist pin 21 is pulled toward a wire laying pin 11 at the speed half of the shift of the position of the wire laying pin from the time when twisting is started, and this shift is absorbed by the shift of the position where the twist pin 21 crosses with a wire material traveling shaft S because of the change of attitude of the twist pin 21 due to the deflection of an elastic piece. Therefore, each tension of the right and left twisted parts of the twist pin 21 is made uniform, and the twisting free from unevenness can be carried out. Further, since, in a twist pin supporting arm which revolves at a high speed, the distribution of the mass of each part for the revolution shaft is balanced exceedingly superior, the noise in the high speed traveling can be reduced.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a winding twisting device, more specifically,
The present invention relates to a support structure for a twist pin that rotates at high speed when twisting the windings in a twisting device that uses an automatic winding machine to wind the ends of a winding wire multiple times and rotates one point in the center to twist the windings.

(Prior art) A bobbin is fixed to a spindle, the spindle is rotated at high speed, and a wire is supplied while moving a wire supply nozzle.
In an automatic winding machine that winds a wire, the end of the winding is performed before and after the winding, and if the wire is thin, it may break because sufficient strength cannot be obtained if the winding is done as is.

In order to solve this problem, a twisting device is used that twists the wire rods in the twisted portion in advance.

FIGS. 6 to 10 are explanatory diagrams showing the operation of an example of the twisting device.

As shown in FIG. 6, the wire 60 is tensioned by the tension pulley 53a of the tension device 53, passes through the nozzle 51a of the wire guide 51 via the pulley 52, and passes through the inside of the rotary cylinder 62 having the twist pin 61. and guided to the winding machine.

The twist pin 61 is for twisting the wire rod 60, and the wire rod 60 is twisted between the pin 71 and the twist pin 61, and the wire guide 51 is moved as shown in FIGS. After winding, the rotating tube 62 is rotated to twist the wires as shown in FIG. 9. In addition,
As the wire rods are twisted together, they become shorter, so the wire hook pin 71 is moved slightly to the left in the figure accordingly.

As shown in FIG. 10, the wire rods twisted together in this manner are pulled in by the movable part 71a of the pin 71 with a cylinder (not shown), and after retracting the pin 71, the wire rod 60 is moved in the direction of the arrow. If it is sent, the mating end will come off the twist pin 61 and advance toward the winding machine.

In addition to this method, there is a method shown in FIG. 11 that improves the efficiency of the alignment work.

In the case of FIG. 11, the wire rod is fixed to the fixed pin holder 82, the wire rod 60 is wound around the pin 71 multiple times, and the central part of the wire rod 60 wound multiple times is The twist pin 91 is arranged, and the rotating tube 92 integrated with the twist pin support arm 90 is driven around the wound wire 60 as an axis, and the twist pin 91 is rotated in the direction of the arrow in the figure. You can add twists in different directions to the left and right.

(Problem to be solved by the invention) Recently, as winding speeds have increased, the heating process for reinforcing the ends of the wire must be performed with the winding temporarily stopped, so the time required to do so has to be shortened. They tend to be highly demanded.

Among the heating methods using conventional twisting devices, the method shown in Fig. 11 simultaneously twists the multi-wound wire from the center to the left and right, so the heating speed is faster than the method in which one end is rotated. If the rotational speed is the same, it is possible to twist at twice the speed.

Moreover, there is no need to worry about this, compared to the case where rotating one end would also twist the adjacent single wire, which could lead to deterioration in the performance of the wire.

This method of simultaneously twisting multiple wound wire rods from the center on the left and right sides has many advantages, but the conventional twisting device using this method has a twist pin 9 as shown in Fig. 11.
The structure of the twist pin support arm 90 that supports 1 is usually unbalanced with respect to the 1 rotation axis, and due to vibration etc.
The rotation speed cannot be increased above a certain level. In addition, as wire rods are shortened due to combustibility, generally only one of the pins of a wire hanger is movable, so if the center twist pin is not moved, the hole created by the center twist pin will become larger and the left and right At the same time, there are drawbacks such as the twisting of the twisted portions becoming uneven.

The purpose of the present invention is to eliminate such drawbacks and to create a structure that supports a twist pin for aligning multi-wound wire from the center to the left and right in a well-balanced symmetrical shape around the rotation axis. By doing so, it is an object of the present invention to provide a winding twisting device that can twist wires at a much higher speed than conventional ones.

Furthermore, it is an object of the present invention to provide a winding twist device having a twist bin support structure that can change the central twist position in response to the shortening of the twisted portion in the process of twisting multiple wound wires. purpose.

(Means for Solving the Problems) In order to achieve the above object, the winding twisting device of the present invention intersects the wire running axis S and a pair of wire hooks disposed at separate positions are connected to pins 11 and 31. , a pair of wire hooks are pin 11.3
1 has a twist pin 21 which is disposed to intersect with the wire rod running axis S and can rotate about the wire rod running axis S as an axis.
1 and the twist pin 21, and twist the wire by rotating the twist pin 21.
The structure of the twist pin support arm 1618 that connects the twist pin drive unit 13 that rotates the rotation axis S is as follows: The structure is such that the cross sections of each part are dynamically balanced and symmetrical about the rotation axis S.

Further, the twist pin support arm 16.18 has a pair of wire hooks that support one of the pins 11.31 with the bottle support portion 4 in between, and a wire hook that is opposite to the pin support portion 4. and a pair of rod-shaped portions 18 parallel to the rotation axis S.
18, the tip and base of which are connected to each other by connecting portions 19.17 that do not intersect with the rotation axis S, and the twist bin support portion 20 engages with each of the pair of rod-shaped portions 18.18, The structure is such that the mounting position can be changed.

Furthermore, the twist pin 21 is supported by the twist bin support part 20 via the elastic piece 22 in a posture inclined to the rotation axis S of the twist pin support arm 16.18.

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

(Example) Examples of the winding twisting device of the present invention will be described below.
This will be explained in more detail with reference to the drawings and the like.

FIG. 1 is a plan view and a front view (sectional view) showing the main parts of an embodiment of the present invention. In addition, the same figure (bl is the same figure (
It is a sectional view cut along AA shown in figure a).

FIG. 5 is a sectional view taken along line DD in FIG. 1 [b).

As shown in FIGS. 1(a), (b), and 2,
The pair of wire hooks 11 and 31 and the twist pin 21 are arranged at positions apart from each other in an attitude that intersects the traveling axis S of the winding wire material, It is placed in the center.

The wire hook 11 is fixed to the front end of the pin support 4, and the vibrator wire hook is fixed to the front end of the pin support 4. The line hook is fixed by being screwed into the threaded part cut inside the pipe of the bottle support tube 3 in the bottle support part 4, and the line hook has a structure that can be replaced when the thickness of the pin 11 needs to be changed. It is said that

The line hook is fixed to the base plate 1 via the pin support tube 3 and the bottle support tube fixing plate 2.

The twist pin 21 is soldered to one end of the elastic piece 22, as shown in FIGS.
It is attached to the twist bin support part 2o via.

Since the elastic piece 22 is elastic, the twist pin 21
As shown by the two-dot chain line in Figure (a), the posture can be changed and the location where it intersects with the wire running axis (same as the twist pin rotation axis) can be moved.

The twist pin support section 20 has a second arm 18 which is a rod-shaped part of the twist pin support arm that supports the twist pin support section 20.
．． 18 is attached to the arm by the elasticity of the material. Therefore, the twist pin 21 can be replaced together with the twist pin supporting portion, and its mounting position can also be finely adjusted.

The second arm 18.18 has a U-shape, and the bent part at the tip (second arm tip connection part 19) avoids the wire running axis S and allows the wire to Lower left when multiple winding.

Alternatively, it is formed to extend from the right to three points.

The other ends of the second arms 18, 18 (the left end in FIG. 1) are connected to the second arm 18 by the arm connecting portion 17
8 and the tip of the first arm 16.16.

The side surface of the arm connecting portion 17 is as shown in FIG.
Notches are made so that the wire does not interfere with the running of the wire, and are formed so that when the wire is wound multiple times, it extends to three points from the lower left or right.

The other end, which is the base of the first arm 16.16, rotates w1
It is fixed at 15.

The rotating tube 15 is a concentric tube with the wire hanging outside the pin support tube 3, and is rotatably attached to the rotating support table 10 and the base til via ball bearings, so that the wire running axis S can be rotated freely. It can be rotated as an axis.

In this way, all cross sections of each part of the first arm 16.16 and the second arm 18.18 are relative to the rotation axis S.
Not only are they symmetrical, but the parts that connect them are also made as close to symmetrical as possible with respect to the rotation axis S, so that the dynamic balance during rotation is considered and designed.

The rotating barrel 15 is driven by rotating a gear 13 attached to one end of the rotating barrel 15 using a motor and a belt (not shown).

The wire hook is attached to the movable part of the bottle support tube 30, and the wire hook is attached to the pin support tube when the winding wire material is wound multiple times or when the wound wire material is twisted together. 3
0, but when the twisting is completed and the wire rod is moved toward the winding machine, the wire hook is pulled into the inside by actuating the movable part of the pin support tube 30 with an air cylinder (not shown). , the wire hook is designed to remove the pin 31 from the wire.

In addition, when twisting the wire rods, the wire rod winding portion becomes shorter due to the twisting.
As shown by the two-dot chain line in the figure, the wire hook moves the entire pin support tube 30 in the moving direction of the wire rod.

The structure and functions of the main parts of this embodiment are as described above. When twisting wire rods according to this embodiment, the first
The wire rod shown in the figure is supported by a guide support stand 42. The wire rod is passed through the guide 41, and the wire rod drives the guide support stand 42. When driven through the guides 41.41, the wire hooks shown in FIG. 1(a) move simultaneously along guide movement paths 40.40. Therefore, the winding wire material is the same as in the prior art, and the pair of wire hooks are pin 11. ．． 31 and a common circumference of the twist pin 21 located between them, the winding guide is wound around the wire running axis S, and after the winding guide stops on the arc of the wire rod 31, the twist pin 21 starts rotating. , twist the wound wire from the center to the left and right.

In this process, as the twisting progresses, the multi-wound portion is twisted and shortened, and the wire hook moves toward the pin 31 and the wire hook moves toward the pin 11 accordingly. At this time, the position of the twist pin 21 is also drawn toward the pin 11 at half the speed of the movement of the position of the bin 3 from the time when twisting is started, but this movement is The change in the posture of the twist pin 21 due to the deflection of the elastic piece 22 is absorbed by the movement of the position where the twist pin 21 intersects with the wire traveling axis S. Therefore, twist pin 2
The tension in the left and right twisted portions of No. 1 is uniform, and even twisting is performed.

In addition, the twist pin support arm, which rotates at high speed, has an extremely well-balanced mass distribution of each part with respect to its rotation axis, so compared to conventional twist pin support structures of this type, it can operate at much higher speeds and generate less noise. Rotation with less is possible.

(Effects of the Invention) As described in detail above, according to the present invention, in a twisting device that twists a multi-wound wire in different directions from the center to the left and right, the support structure that supports the twist pin is connected to the rotation axis of the twisting device. By creating a shape that is as well-balanced as possible, the heating rate of the wire can be made faster and less noisy than in the past, and the winding process can be speeded up.

Furthermore, by adding elasticity to the support of the twist pin, it can cope with the reduction of the same part of multiple windings due to twisting.
Do not create excessive tension. Therefore, although the structure is inexpensive and simple, it is possible to perform uniform twist reinforcement even during high-speed operation.
