Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a winding device, and in particular,
The present invention relates to a device for traversing a traveling yarn left and right in a direction parallel to an axis of a package in which the yarn is wound.

[0002]

BACKGROUND OF THE INVENTION In one form of such a traverse device, the device comprises a roll and a yarn guide device. The roll is provided in the textile machine, is located in the vicinity of the package in which the running yarn is wound and is rotatable about an axis parallel to the axis of the package. This roll is provided with a double spiral endless groove on the cylindrical surface, and the yarn guide device is provided in the driven part, the driven part located in this groove, and extends parallel to the axis of the roll and the package. The guide post is regulated between two guide rails spaced apart from each other, and the thread guide provided on the guide post is provided. The rotation of the roll moves the yarn guide device left and right between the guide rails. Such devices have been used for many years in numerous textile machines for winding yarn packages.

[0003]

However, the center of gravity of such a yarn guide device is deviated from the driven part, and the yarn tension acting on the yarn guide device is further apart from the driven part, so that the yarn guide device rolls. There is a tendency to tilt in the groove, which results in uneven wear of the follower. Therefore, it is necessary to replace the yarn guide device with a relatively frequent cycle. In addition, lint and other debris falling between the two guide rails and entering the groove of the roll accelerates this wear and impedes the traverse movement of the yarn guide device. Further, the lubricant applied to the guide rail and the guide post easily contaminates the running yarn.

[0004]

OBJECT OF THE INVENTION It is an object of the present invention to provide a winding device of the type mentioned above, which device makes it possible to eliminate or reduce the abovementioned drawbacks.

[0005]

According to the present invention, a winding device includes a long roll having an endless guide structure on a cylindrical surface, a guide means arranged in the vicinity of the roll and extending in the longitudinal direction thereof, and A yarn guide device, the driven part adapted to slide in the longitudinal direction of the roll guide structure, the yarn guide provided at one end of the driven part, and the other end of the driven part. The driven guide structure regulates the movement of the yarn guide device in a direction parallel to the guide means in cooperation with the guide means.

The guide means may be provided so as to extend substantially parallel to the axis of the roll. The roll guide structure may consist of an endless groove formed on the cylindrical surface of the roll, or may have a double spiral shape. The driven guide structure may be a guide post provided on the driven portion, in which case the guide means is a pair of parallel guide rails with a guide post provided therebetween. Alternatively, the driven guide structure may be a long groove-shaped guide rail having a cooperating structure therein and extending along the guide rail. Alternatively, the driven guide structure may comprise a laterally extending groove of the driven portion, in which case the guide means comprises a long rib-shaped cooperating structure extending along the guide rail. It may be a guide rail provided above. The cooperating structure may be provided on the lower surface of the guide rail.

The follower may be made of an injection molded plastic material and the thread guide may be made of a ceramic material.

FIG. 1 is a perspective view showing an embodiment of a winding device according to the present invention, FIG. 2 is a perspective view of an embodiment of a yarn guide device, and FIG. 3 is a perspective view of a second embodiment of the yarn guide device. FIG. 4 is a partial cross-sectional view of a winding device similar to FIG. 1 provided with the yarn guide shown in FIG. 2, and FIG. 5 is shown in FIG. 1 provided with the yarn guide device shown in FIG.
6 is a partial sectional view of the winding device shown in FIG. 6, and FIG. 6 is a partial sectional view of the winding device provided with the yarn guide device shown in FIG.

A winding device 10 is shown in FIG. 1, the winding device 10 acting to wind a running yarn 11 into a package 12 provided on a textile machine 13, which winds the fiber. It constitutes a part of the machine 13. The winding device 10 has a long roll 14 provided such that its axis 15 is parallel to the axis 16 of the package 12, and a guide means 1 provided in the vicinity of the roll 14 and extending in the longitudinal direction thereof.
7 and a yarn guide device 18. The guide means 17 includes an axis 15 of the roll 14 and the package 12,
It has a rail shape extending substantially parallel to 16.

The roll 14 has a double spiral groove-shaped endless guide structure 19 formed on the cylindrical surface 20 of the roll 14. As shown in more detail in FIGS. 2 to 6, the yarn guide device 18 includes a long follower 21 (preferably made of injection molded plastic material), a follower 21.
Guide 2 made of ceramic material and provided at one end of the
2 and a driven guide structure 23 provided at the other end of the driven portion 21.

In the embodiment shown in FIG. 2, the driven guide structure 23 is in the shape of a guide post 23a, while the driven guide structure shown in FIG. 3 is a slot 23b extending laterally of the driven portion. It has the shape of. In any of the embodiments, the driven portion 21 has a “boat shape” when seen in a plan view.
Or it is oval in shape, allowing its orientation to change smoothly within the roll groove 19 as the end of the traverse stroke is reached and the groove 19 changes from one spiral to the other in the opposite direction.

As the roll 14 rotates, the yarn guide device 18 is moved by the reaction force between the groove 19 and the wall of the driven portion 21. This movement is restricted in the direction parallel to the guide means 17 by the reaction force between the driven guide structure 23 and the guide means 17.

In the embodiment shown in FIG. 4, a driven guide structure 23 in the shape of a guide post 23a is provided between two parallel and spaced guide rails 17a, 17b. Form guide means 17.

In the embodiment shown in FIG. 5, the driven guide structure 23 is in the shape of a guide post 23a and a long groove 24 extending along a single guide rail 17.
It is provided in a cooperating structure 24 in the shape of a.

In the embodiment shown in FIG. 6, the driven guide structure 23 is in the shape of a traverse slot 23b, in the shape of a long rib 24b extending along a single guide rail 17 therein. A cooperating structure 24 is provided.

In all the embodiments described above, the center of gravity of the yarn guide device 18 is very close to the intermediate height of the driven part 21. In addition, the yarn guide 2 by the tension of the traveling yarn 11
The force acting on 2 is very close to the driven part 21.
Therefore, the tendency of the yarn guide device 18 to tilt due to the force acting on it is significantly reduced compared to that which occurs in the known yarn guide device in which a relatively heavy ceramic yarn guide 22 is provided on the top surface of the guide post 23. It By reducing this tilting tendency, the uneven wear of the driven post, which was characteristic of previously known yarn guiding devices, is reduced. Further, the risk that the yarn 11 is contaminated by the lubricant of the guide rail 17 and the driven guide structure 23 is far less likely to occur in the device according to the present invention as compared with the conventionally known device. Particularly in the case of the embodiment shown in FIG. 5, the tendency of lint and other debris to impede the movement of the yarn guide device 18 is reduced compared to previously known devices. Furthermore, in order to prevent such dust and the like from falling into the groove 19, a cover 25 may be provided as shown in FIG.
Further, the guide rail 17 may achieve a covering effect.

Other embodiments of the winding device according to the present invention will be readily apparent to those skilled in the art. For example, the endless guide structure on the cylindrical surface of the rail may be rib-shaped, and the thread guiding device may in this case be a "saddle" structure mounted on the rib.
