Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a synthetic fiber yarn 10
The present invention relates to a yarn winding machine and a traverse device capable of winding at a speed of 00 m / min or more.

[0002]

2. Description of the Related Art When a synthetic fiber yarn is wound around the end of the package without causing a selvage, for example, JP-A-58-58 is used.
A winder equipped with a traverse device as described in Japanese Patent No. 78955 is used.

In the traverse apparatus, a traverse guide is provided at the tip of an L-shaped lever, the L-shaped lever is reciprocated, and the angle of the L-shaped guide is changed at both ends of the reciprocal movement, thereby the traverse guide. It is configured to change the traverse stroke of.

In the traverse device having such a structure, the mass of the reciprocating part becomes large, the noise due to the impact due to inertia is large, and the part is damaged due to the impact, so that it cannot be operated at a high speed and 1000 m / It has been used for winding a false twisted yarn at a low speed of about min.

On the other hand, in the spinning winding process of winding at a speed of 3000 m / min or more, the traverse device described above cannot be used. Therefore, a traverse device that does not change the traverse stroke is used.

However, when the yarn is wound by the traverse device that does not change the traverse stroke, the load of the touch roll is concentrated on the edge of the wound yarn body at the height of the selvages, especially inside the fiber. When winding a semi-undrawn yarn (POY) having an unstable structure, the yarn is damaged and stretch unevenness is generated in the drawing false twisting step of the subsequent process, etc. There has been a problem that partial dyeing spots occur in the length direction of the yarn.

In order to solve such a problem, Japanese Patent Laid-Open No. 9-
A touch roll as described in 202522 is formed into a shape having a difference of 0.1 to 2.0 mm in the outer diameter dimension at the position where it comes into contact with the end of the wound body and the position at the center of the wound body. A method has been proposed.

However, despite the fact that the height of the selvage, that is, the difference between the diameter of the outer peripheral end of the wound body and the diameter of the center, varies depending on the type of yarn, the type of oil agent used, and the winding conditions. Since the shape (dimension difference) of the touch roll is fixed, there is a problem that it cannot be a radical solution with general versatility.

[0009]

The problem of the present invention is 300
It is an object of the present invention to provide a traverse device and a yarn winding machine that can wind a yarn at a speed of 0 m / min or more and that can obtain a wound body with high yarn quality that does not cause ear height. .

In order to achieve the above-mentioned object, the traverse device of the present invention has a pair of flanges mounted on a shaft so as to have a predetermined space, and a yarn guide. A plurality of guide members each having a portion and attached to the flange at predetermined intervals in the circumferential direction so that the yarn sequentially contacts the yarn guide portion by the rotation of the flange and traverses the yarn in the axial direction. And the pair of flanges are configured so that the phase in the rotational direction can be changed.

Further, in the yarn winding machine of the present invention, as described in claim 2, the traverse device is a yarn winding device which is the traverse device according to claim 1.

10-8a) has a relationship as shown in FIG.

The bearing 9 is made of a cylindrical synthetic resin having abrasion resistance or the like, and the bearing is not particularly limited as long as it can be operated for a long time without lubrication.

The guide member 10 is made of aluminum alloy, stainless steel or the like, and a guide having abrasion resistance such as ceramic is attached to the thread guide portion 10a by adhesion or the like. It can be formed by a member having abrasion resistance and provided with the thread guide portion 10a, and the cross-sectional shape is not limited to a rectangle having an arc shape at one end, and may be a square, a triangle, an ellipse, a circle, or the like. it can.

Then, the servo motor 16 operates to operate the shaft 1
When 6a rotates, the bearing 18 moves together with the positioning plate 17 to move the second flange 8 toward the first flange 6, and the distance between the first flange 6 and the second flange 8 becomes (W1). Since the length dimension (L) of the guide member 7 does not change even if the spacing dimension is reduced, the first dimension is changed from the state shown in FIG. 4 to the first dimension as shown in FIG.
The flange 4 is rotated in the same direction as the rotation direction of the shaft 3a of the motor 3, and the first flange 6 and the second flange 8 have a phase difference in the rotation direction of (θ), thereby causing a traverse stroke as shown in FIG. Becomes (TW1).

Next, when a preset time elapses, the servo motor 16 is actuated, the shaft 16a is reversely rotated, the second flange 8 is moved in the axial direction and returned to the original position, and the first flange 6 and the first flange 6 are removed. When the distance between the two flanges 8 is (W0), there is no phase difference in the rotational direction between the first flange 6 and the second flange 8, and the traverse stroke is (TW0).
Then, the state shown in FIG. 5 is changed to the state shown in FIG.

When a preset time elapses in this state and the servo motor 14 operates to rotate the shaft 14a, the motor 3 moves together with the movable bed 15 and the first flange 6 moves toward the second flange 8. Then, the distance between the first flange 6 and the second flange 8 becomes (W1) as in the case where the above-mentioned second flange 8 is moved. Since the length dimension (L) of the guide member 7 does not change even if the space dimension is reduced, the first first flange 6 is attached to the shaft 3a of the motor 3 from the state shown in FIG. 4 to the state shown in FIG. Due to the rotation, the shaft 3a is rotated in the same direction as the rotation direction of the shaft 3a, and the first flange 6 and the second flange 8 have a phase difference in the rotation direction of (θ), and the traverse stroke becomes (TW1). The stroke becomes (W1) / (W0) times shorter.

Next, when a preset time elapses, the servo motor 14 is actuated, the shaft 41a is reversely rotated, the first flange 6 is moved in the axial direction and returned to the original position, and the first flange 4 and the second flange 4 are returned. The distance between the flanges 6 becomes (W0), the phase difference in the rotation direction disappears, and the traverse stroke returns to (TW0).
