Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a traverse device for traversing one yarn by a plurality of blades mounted on a pair of rotating bodies which rotate in opposite directions.

[0002]

2. Description of the Related Art Generally, when winding a yarn spun from a spinning machine, a bobbin mounting spindle rotatably mounted on a machine frame and a spindle located above the spindle and capable of moving up and down on the machine frame. A winder composed of a traverse device attached to the machine or a turret type winder in which a plurality of bobbin mounting spindles are rotatably mounted on a turret member that is rotatably supported by a machine frame is used. Has been done.

The traverse device installed in the winder for winding the yarn at a high speed has a pair of rotating bodies rotatably installed on the frame body at a predetermined interval and is attached to each rotating body. And a plurality of blades and a thread guiding guide attached to the frame so as to be located within the rotation trajectory of the thread guiding edge portion of the blade form one traverse unit, and the traverse unit is mounted on the bobbin. A plurality of units are provided at a predetermined interval in the axial longitudinal direction of the spindle, and a touch roller is rotatably attached to the frame body so as to be positioned close to the downstream side of the blade of the traverse unit.

In the traverse unit, the blades are attached to the rotating body so that the two blades are offset by 180 ° and the three blades are offset by 120 °.
A pair of rotating bodies to which the same number of blades are attached are rotatably attached to the frame body so as to have a predetermined interval, and the rotating bodies are rotated in opposite directions.

Traverse devices having such a structure are disclosed in, for example, Japanese Patent Publication No. 3-72544 and Japanese Patent Publication No. 4-2715.
It is described in Japanese Patent No.

In the traverse device as described above, since the axial distance between the rotating bodies in each traverse unit becomes extremely short, it is almost impossible to directly transmit the rotation from one rotating body to the other rotating body. It is possible to make each rotary body rotate by its own drive mechanism, or install an intermediate gear and mesh with a gear attached to each rotary body, and make one rotary body a common drive mechanism. It is necessary that the other rotating body is simultaneously rotated when rotated by.

When the intermediate gears are installed as described above, the structure becomes very complicated, and there is a problem that a lot of time is required for machining, assembling, and maintenance of parts.

In the package wound by the traverse device as described above, the turning point of the yarn and the running locus of the yarn are at the same position from the winding start to the winding end. As the size increases, there is a problem that the frequency of overlapping yarns in the ribbon region also increases.

Therefore, in order to reduce the height of the ears generated in the package and the size of the ribbon, the shape of the thread guide edge of the blade attached to the rotating body is made different, and the folding position of the thread and the running locus are provided at a plurality of locations. The method (end face ear breaking method) has been proposed.

Such a traverse device having a plurality of folding positions is described in, for example, Japanese Patent Publication No. 49-2394.

The above-described method of forming the yarn guide edges of the blades in different shapes has a problem in that the yarn turning point can be equal to the number of blades.

When the number of folding points is two or three, the ends are likely to be stepped, and the number of blades is increased to 6 to 8 in order to further reduce the height of the ears. Then, there is a problem that the traverse device becomes very large and cannot be put to practical use.

[0013]

The first problem is two sheets,
Alternatively, in a traverse device in which a pair of three rotating bodies having the same number of blades are eccentrically eccentrically mounted so as to be freely rotatable, the axial center spacing of the rotating bodies is extremely short, and one rotating body can rotate the other rotating body. In order to rotate, it is necessary to install parts such as intermediate gears, which complicates the configuration and requires a lot of time for parts working, assembling, and maintenance.

The second problem is that even if the shapes of the thread guide edges of all the three blades are different, the turning points of the thread can be set only at three points, and the ear height and the ribbon are used as products. The point is that the size cannot be affected.

The third problem is that the turning point cannot be changed without replacing the blade.

[0016]

In order to solve the first problem, in the traverse device of the present invention, the number of blades mounted on the first rotary member is set to m, and the traverse device is mounted on the second rotary member. The number of blades is set to n (m ≠ n), the blades are arranged so that they are equally divided on the circumference on the rotation plane, and the rotations of the first rotating body and the second rotating body are made. The center position is rotated by one blade on one rotating body contacting the yarn to move the yarn along the yarn guiding guide, and then by the time the yarn on the other rotating body begins to guide the yarn. When the rotation angle of the rotating body is the first rotating body, it is approximately 360 ° / 2m.
In the case of the second rotating body, the rotation speed ratio between the first rotating body and the second rotating body is n.
It is configured to be a pair m.

In order to solve the second problem, the traverse device of the present invention uses the number of blades mounted on the first rotor as m.
The number of blades attached to the second rotating body is set to n (m ≠ n), and each blade has a thread guide edge formed at the end of the blade on the rotation plane. The first rotating body and the second rotating body are mounted so as to be different from the position where the top is equally divided.

In order to solve the third problem, in the traverse device of the present invention, the mounting position of each blade is changed with reference to the arcuate guide portions formed on the first rotating body and the second rotating body, respectively. It has a configuration that allows it.

4-4, a toothed belt 27 stretched around a toothed pulley 10c formed on the first rotating body 10.

When the electric motor 25 is operated and the first rotating body 10 of each of the traverse units 4-1 to 4-4 is rotated, the gear 10b formed on the first rotating body 10 causes the first rotating body 10 and The two rotating body 15 is rotated.

The attachment of the blades 12-1 to 12-3 to the first rotating body 10 and the attachment of the blades 17-1 and 17-2 to the second rotating body 15 in the traverse units 4-1 and 4-3 described above will be described below. Do as follows.

Here, the traverse unit 4-1 will be described.

First, in order to perform the temporary positioning, as shown in FIG. 4, the blades 17-1 and 17-2 are 18 viewed from the rotation plane.
The blades 12-1 to 12-3 are attached to the second rotating body 15 so that the angle is shifted by 0 °, that is, the point is symmetrical with respect to the point (P), and the blades 12-1 to 12-3 are angled by 120 ° when viewed from the rotation plane. When attached to the first rotating body 10 so as to be displaced, the blades 17 from the yarn delivery position (A) to the yarn delivery position (B)
The position of the point (P) is determined so that the rotation angle of 1 and 17-2 is 90 °. Further, the point (R) and the yarn guiding guide 20 are set so that the rotation angles of the blades 12-1 to 12-3 from the yarn delivering position (B) to the yarn delivering position (A) are 60 °.
Determine the position of.

The above-mentioned point (P) is the rotational axis center position of the second rotating body 15, and (R) is the rotational axis center position of the first rotating body 10.

Further, the gear 10a formed on the first rotating body 10 and the gear 19 attached to the second rotating body 15 are arranged so that the rotation ratio of the first rotating body 10 and the second rotating body 15 is 2 to 3. The number of teeth is determined, and the first rotation is performed so that the blades 12-1 to 12-3 and the blades 17-1 and 17-2 intersect at each yarn transfer position (A) and (B) so that the yarn can be transferred. The meshing position of the gear 10b of the body 10 and the gear 19 of the second rotating body 15 is selected.

Then, the point (P) determined by the above method,
(R), the yarn guiding guide 20, the first rotating body 10 and the second rotating body 15 are kept as they are, and the actual blades 12-1 to 12-3 and the blade 17- are shown in FIG. Adjust the position of 1, 17-2.

First, with reference to the blade 12-1, the blade 12-1
The blade 12-3 is moved clockwise so that the angle between the blade and the blade 12-3 is smaller than 120 °, and the first rotor 1 is rotated.
The blade 12-2 is fixed to 0, and the blade 12-2 is moved counterclockwise so that the angle between the blade 12-1 and the blade 12-2 is smaller than 120 ° and fixed to the first rotating body 10. In addition, the blade 17-1 is moved counterclockwise from the above position to the blade 1
7-2 is moved clockwise and fixed to the second rotating body 15.

That is, the blades 12-1 to 12-3 are based on the straight line (RE) passing from the point (R) in FIG. 5 to the point (E) of the yarn guide edge formed at the tip of the blade 12-1. Then, a straight line (R
F) On the other hand, the blade 12-3 is in contact with the straight line (RF ') displaced by θ-1 in the rotation direction (clockwise direction), and is 1 in the clockwise direction.
The blade 12-2 is attached so as to be in contact with the straight line (RG ') displaced by θ-2 in the direction opposite to the rotational direction (counterclockwise) with respect to the straight line (RG) displaced by 20 °.

Further, the blade 17-1 and the blade 17-2 have the gear 19b of the second rotating body 15 and the gear 19b of the second rotating body 15 on the basis of the straight line (RE) in the blade 12-1 described above. In the meshed state, the blade 12-1 and the blade 17-1 are formed at the tip of the blade 17-1 in a state where the blade 12-1 and the blade 17-1 cross each other at the thread delivery position (A) on the thread guide 20 to deliver the thread. The point (S) of the yarn guiding edge and the point (T) of the yarn guiding edge formed at the tip of the blade 17-2 at a position shifted by 180 ° with respect to the point (S) are set. Next, with reference to the straight line (SPT) where the point (S) and the point (T) contact, the blade 17
-2 is touched by a straight line (PT ') displaced by θ-4 in the rotation direction (clockwise), and blade 17-1 is displaced by θ-3 in the opposite direction (counterclockwise) to the rotation direction. Attach it so that it touches the straight line (PS ').

The above-mentioned displacement angles θ-1 to θ-4 differ depending on the thread thickness, the type of thread, the winding speed, etc., but they are point (F) and point (F ') and point (G) and point (G). The distance between (G '), point (S) and point (S'), point (T) and point (T ') is 0.5 to 3 mm.
It is preferable to set it so that it becomes a degree.

The movement of each blade in the above traverse unit 4-1 will be described.

First, when the first rotating body 10 is rotated clockwise, the yarn is conveyed by the blade 12-1 on the yarn guiding guide 20 from the delivery position (B) toward the delivery position (A). When the blade 12-1 reaches the delivery thread (A), the thread intersects with the blade 17-1 attached to the second rotating body 15 which is rotated counterclockwise, and the thread moves from the blade 12-1 to the blade. It is delivered to 17-1. Then, the yarn is conveyed toward the delivery position (B) by the blade 17-1, and when the blade 17-1 reaches the delivery position (B), the yarn intersects the blade 12-3 and the yarn 17- It is delivered from 1 to the blade 12-3. By this operation, the yarn makes one round trip. Subsequently, the blade 12-3 to the blade 17-2 at the transfer position (A), the blade 17-2 to the blade 12-2 at the transfer position (B), and the blade 12-2 to the blade 17-at the transfer position (A). 1, from the blade 17-1 to the blade 12-1 at the delivery position (B),
Blade 12-1 to blade 17-2 at the delivery position (A)
In the delivery position (B), blade 17-2 to blade 12
-3, blade 12-3 to blade 1 at the delivery position (A)
7-1, from the blade 17-1 to the blade 12-2 at the delivery position (B), from the blade 12-2 to the blade 17-2 at the delivery position (A), from the blade 17-2 at the delivery position (B). The yarn is sequentially delivered to the blade 12-1 and returns to the initial state.

Thus, the yarn is traversed on the yarn guide 20 by being successively delivered by the three blades 12-1 to 12-3 and the two blades 17-1 and 17-2.

The movement of the yarn traversed by the above-mentioned blades is as shown in FIG. 6, and the position of the yarn between the package widths A and B is continuously shown in the up and down direction of the time and in the left and right direction. It is shown in.

Here, the blade 12-displaced in the rotational direction
The blades 3 and 17-2 are (+) displaced blades, and the blades 12-2 and 17-1 displaced in the direction opposite to the rotating direction are blades displaced (-).

When the above traversing operation is repeated, the blade 17-2
Is displaced to (+), blade 17-1 is displaced to (-), blade 12
Since -3 is displaced (+) and blade 12-2 is displaced (-), the relationship between the position of the yarn and the time is as shown by the solid line in FIG. Have a relationship,
It can be seen that the folding position moves synchronously.

Next, the change in the yarn delivery position between the blades is as shown in FIG. 7, and for the blade displaced to (+) to the blade displaced to (+) or the blade displaced to (-). The delivery position is different.

Here, if θ-1 to θ-4 are all set to different division angles, there are six folding points. That is, the three blades 12-1 to 12-3 and the two blades 17-1 and 17-2 are sequentially combined, and 3 × 2 = 6 combinations are generated.

In this embodiment, six traverse inversion positions can be obtained.

When the number of blades is 3 and 4 and the blades have different division angles, the folding point can be 12 points.

Although the folded-back portion of the yarn in FIGS. 6 and 7 described above is indicated by a dot, when the yarn is actually wound on the package, the yarn contact point (U) of the yarn guiding guide 20 in FIG. ) And the yarn contact point (W) of the touch roller 5 is relaxed by a free length, and the line is folded back along a smooth curved locus, and the folded back line is different depending on the shape of the tip guide portion of each blade. Become.

When the ribbon region, that is, the traverse period and the number of revolutions of the package have an integer ratio or an integer fraction ratio, for example, when the package makes two revolutions while the yarn makes one reciprocation, the yarn in the ribbon region is As for the locus on the package surface, since the yarn returns to the same locus only after the yarn reciprocates six times, the growth of the ribbon is delayed, and it is possible to prevent the loop slippage from occurring during the unwinding operation.

As is apparent from the development view of the secondary ribbon shown in FIG. 8, the intersection (K) intersects at six points, and the growth of this portion in the thickness direction of each blade is made. The speed is ⅙ of that when the mounting position is not displaced, and since the threads are not continuously wound on the same trajectory, the threads do not overlap at both ends of the traverse and are being unwound. It can be seen that the yarn and the yarn to be unwound next are not pulled out at the same time. For these reasons, it is possible to prevent sudden tension fluctuations from occurring when the yarn is unwound, and it is possible to unwind the yarn at a high speed.

When two blades and three blades are combined as described above, the distance between the rotation center point (R) of the first rotating body 10 and the rotation center point (P) of the second rotating body 15 is It becomes about 1/3 of the traverse width dimension. Therefore, the traverse width is 12
In the case of 3 mm, the axial distance between the first rotating body 10 and the second rotating body 15 is approximately 42 mm, and in the case of a traverse width of 85 mm, the axial distance is approximately 30 mm, and the gears attached to each rotating body are directly meshed. Therefore, the rotation can be transmitted.

Polyester yarn (75D, 36 filaments) was traversed by the traverse device described above:
123mm, Twill angle: 5.7 °, Winding speed: 3100m /
min, package diameter dimension at the end of winding: 420 mm,
The state where the mounting position of each blade is not changed and each blade is about 1 mm
The hardness distribution of the package obtained by winding in a displaced state and measured by a JIS A hardness tester is shown in FIG.
It can be seen that the hardness difference when the blade mounting position is displaced is smaller than that when the blade mounting position is not changed.

Further, the amount of raised edges (α) at both ends of the package
The relationship between the end face bulge amount (β) is as shown in Table 1,
It can be seen that the size is smaller when the mounting position of each blade is displaced.

[0052]

[Table 1] The number of blades attached to the first rotating body 10 and the second rotating body 15 is a small number of blades when a combination of an odd number and an even number such as three and four or three and four. You can get more turning points.

[0053]

According to the traverse device of the present invention, as in claim 1, the number of blades mounted on the first rotating body is m, and the number of blades mounted on the second rotating body is n ( m ≠ n)
At the same time, the blades are arranged so that they are equally divided on the circumference on the plane of rotation, and
At each rotation center position of the rotating body and the second rotating body, one blade on one rotating body comes into contact with the yarn to move the yarn along the yarn guide guide, and then the blade on the other rotating body. The rotation angle of the rotating body that rotates before the yarn starts to be guided is set to about 360 ° / 2m for the first rotating body and about 360 ° / 2n for the second rotating body. Since the rotational speed ratio of the first rotating body and the second rotating body is configured to be n to m, the axial distance between the first rotating body and the second rotating body becomes large, and parts such as intermediate gears are provided. Can be rotated directly without installing, and the structure can be simplified, and the processing time of parts, assembly work, and maintenance work time can be shortened.

According to a second aspect of the present invention, the number of blades attached to the first rotating body is set to m, and the number of blades attached to the second rotating body is set to n (m ≠ n).

According to a third aspect of the present invention, when the respective blades are arranged so that the mounting positions can be changed with reference to the arcuate guide portions formed on the first rotating body and the second rotating body, respectively, the folding position of the thread Can be changed easily.
