BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a traverse device for traversing a yarn at the time of winding a yarn, for example, when forming a package.

[0002]

2. Description of the Related Art When winding a yarn such as forming a package or bobbin, the yarn is wound in a predetermined shape in the axial direction. Do. In order to perform this traverse, a traverse guide for guiding the yarn to be wound is reciprocated in the axial direction. Various methods have been proposed and implemented as driving means for the traverse guide. As one of them, a traverse guide is fixed to a traverse rod supported reciprocally in an axial direction and a follower member is protruded, and this follower member is fitted into a cam groove of a drum having a cam groove on a surface. In some cases, the follower member is reciprocated in the axial direction along the cam groove of the drum by the rotation of the drum, whereby the traverse guide provided on the traverse rod is reciprocated in the axial direction to perform traverse.

[0003] In the traverse using such a traverse rod, the traverse rod is usually formed by a single or long connecting member, and the traverse guides of a winding device arranged in a large number are arranged on the traverse rod. The traverse rod is driven by one drum fixed to the end of the traverse rod, thereby simultaneously driving the traverse guides of the winding device arranged in a large number.

[0004]

In the above-described apparatus for performing traverse using the traverse rod, the follower member is guided by the cam groove formed in the drum. The reversal is performed by reversing the guide direction of the cam groove at the axial end of the drum. In this reversing part, the cam groove may change its direction greatly, and the traverse rod changes its moving direction rapidly. Therefore, a traverse rod having a length of about several tens of meters and having a large number of traverse guides is provided. Receives a large inertial force and reverses the moving direction. As a result, the traverse rod bends between the support portions due to the compressive force.

[0005] Such bending of the traverse rod also occurs between the supporting metals provided at both ends where the follower member reciprocatingly guided by the cam moves. Therefore, the follower member jumps in the cam groove due to the bending of the traverse rod, and collides violently with the wall surface forming the cam, generating loud noise and possibly damaging the cam and the follower.
Further, the traverse rod bends between the supporting metals arranged in the axial direction, and at that time, the rod moves in a minute gap between the supporting metal and the rod, and the rod collides with the inner surface of the supporting metal. For this reason, each time the direction of movement of the traverse rod is reversed at each support metal portion, a collision noise is generated, and there is a drawback that a loud noise is generated in the factory together with the noise in the cam groove.

In particular, in recent years, a traverse rod has tended to use a carbon rod having a high strength. Therefore, a metal portion using a gunmetal tends to be worn, and a bearing gap is increased, so that the noise is further increased. There is.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a noise prevention device for a traverse device that does not generate a large noise when the moving direction of the traverse rod is reversed.

[0008]

According to the present invention, in order to solve the above-mentioned problems, a traverse guide and a follower member are mounted on a traverse rod, and a cam groove formed in a rotary drum is used for the hologram.
In the traverse device that guides the lower member to reciprocate the traverse rod, the traverse device is located outside the reciprocating range of the follower member.
A pair of bearings that slidably support the traverse rod
And one shaft outside the pair of bearings.
By providing a pair of guide rollers for holding and guiding the traverse rod between the receiver and the traverse guide, a noise prevention device of the traverse device is constituted, thereby generating a large noise when the traverse rod reverses the moving direction. It does not occur.

[0009]

SUMMARY OF Invention The present invention, since the structure described above, when the moving direction of the traverse rod reversal, by the inertia force of traverse rod, although the traverse rod near the drive unit is going to deflect, bearing and traverse guide and the By providing a pair of guide rollers between the traverse rods, the traverse rods are clamped, so that the traverse rods are restrained from bending, and the noise caused by the traverse rods is prevented from being generated.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings. A traverse guide 4 that traverses the yarn Y by reciprocating in the axial direction with respect to a package P that is supported by the cradle 2 and is driven in contact with the winding drum 3 is fixed to the traverse rod 1. . Although not shown, a large number of such winding devices W are arranged in the axial direction of the traverse rod 1.

A follower member 5 is fixed to the shaft end of the traverse rod 1. A follower 6 provided at the tip of the follower member 5 has a cam formed on the outer peripheral surface of a rotary drum 7 which is driven to rotate from the outside. The follower member 5 moves in the axial direction along the cam groove 8 when the rotary drum 7 rotates, so that the follower member 5 is inverted at the shaft end side of the rotary drum 7. , The follower member 5 is also inverted, so that the follower member 5 reciprocates along the cam groove 8, and the traverse rod 1 also reciprocates.

Outside the reciprocating range of the follower member 5, cylindrical cylindrical metal bearings 9, 9 for supporting the traverse rod 1 are provided.
Is provided. As shown in FIGS. 2 and 3, shafts 11 and 12 attached to a frame 10 are provided with a pair of bearings 9 and 9.
A pair of guide rollers 13 and 14 are supported on the side and between one of the bearings 9 and the traverse guide 4 so as to clamp the traverse rod 1. Guide rollers 13, 14
May be baked with a rubber material on its outer peripheral surface, or may be provided with a depression on its outer periphery.

As shown in FIG. 4, a pair of holding rollers 22 and 23 rotatably supported by shafts 20 and 21 hold the traverse rod 1 at appropriate positions in the axial direction of the traverse rod 1. Is attached to the frame 24. The holding rollers 22 and 23 have recesses 25 and 2 on the outer circumference.
6 are provided, and the horizontal and vertical vibrations are prevented by the depressions 25 and 26.

In operation of the above device, the follower member 5 is guided by the cam groove 8 by the rotation of the rotary drum 7, and the traverse rod 1 reciprocates in the axial direction. Package 3
Traverse of the yarn Y to be wound.

As the cam groove 8 reverses on the shaft end side of the rotary drum 7, the follower member 5 also reverses, and the moving direction of the traverse rod 1 also reverses. At that time, the traverse rod 1 moving with a large inertia due to the weight of the traverse rod 1 and the weight of the traverse guide 4, etc., tends to bend as shown by the two-dot chain line in FIG. This bending B is suppressed to some extent by bearings 9, 9 that support the traverse rod 1 on both sides of the follower member 5.
However, the bearings 9, 9 have a gap between the inner surface of the bearing and the outer peripheral surface of the traverse rod due to abrasion even during play and slide play existing from the beginning, so that the deflection of the traverse rod 1 is sufficiently suppressed. I can't stop it.

According to the present invention, such a movement of the traverse rod 1 to be flexed is strongly restrained by the pair of guide rollers 13 and 14, as shown in FIG. Inverted and reciprocated in a substantially linear state.

[0017]

Since the present invention is constructed and operates as described above, it is possible to prevent the traverse rod from bending when the traverse rod is reversed in the axial direction, so that the traverse rod can be bent. Can prevent the occurrence of various noises. Further, since such noise can be reduced, the moving speed of the traverse rod can be further increased, and the work efficiency of the winding device is improved.
