DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a winding device for a tube winding machine, a twining machine and a text yard processing machine having a yarn path which can be moved linearly.

[0002]

2. Description of the Related Art In a tube winding machine, a yarn path is mainly used. Grooved drum winders or splined groove winders are known. Here, the yarn is guided directly into the groove of the drum. These known machines have the disadvantage that the thread runs relatively close to the machine part to be lubricated, so that the thread can become soiled. Previously, tube winding machines with a reciprocating yarn path were also used, with linear movement being performed through eccentrics. However, this known machine has a limited processing speed.

[0003]

SUMMARY OF THE INVENTION The object underlying the present invention is to provide a winding device which allows a high processing speed and prevents yarn contamination.

[0004]

In a winding device of the type mentioned at the outset, in order to solve this problem, according to the invention, the rotational movement of the drive shaft is converted into a linear movement of the yarn path and 3

Supported at the outer end of the displacement arm to hold the thread path and
A second arm driven to rotate is provided, and the second arm is

You .

[0005]

The triple speed ratio according to the invention allows a very high speed of the yarn path to be obtained. In addition, an expediently meshing planetary gearing provides sufficient spacing between the thread and the machined part to be lubricated. Therefore, the winding device according to the present invention has no risk of contamination.

[0006] A planetary gear device has a first planetary gear revolving in an internal ring gear, and a displacement arm is rotatably supported on a rotating shaft of the planetary gear. A driven second arm is provided to hold the thread path. In this way, a significantly higher speed of the yarn path is obtained, in contrast to the known eccentric drives. The second arm is driven by a gear provided on the displacement arm and connected to the second planetary gear via a toothed belt or chain. By appropriate selection of the gear ratio, the speed of the yarn path can be increased. Furthermore, three gear ratios prevent the yarn path from stopping unnecessarily long at its reversal point.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the winding device according to the present invention will be described below with reference to the drawings. Winding device 10 according to FIG.
Has a drive shaft 11 which is fixedly connected to a disk 12. Below the disk 12, a first planetary gear 13 is eccentrically supported rotatably about an axis 14. First
The planetary gear 13 revolves along an internal gear 15 provided on a fixed disk 16. A displacement arm 17 is likewise supported on the first planetary gear 13 so as to be rotatable about an axis 14. The structure above the displacement arm 17 can be seen from the detailed view of FIG. Above the displacement arm 17, a second arm 18 is provided rotatably about an axis 19. This second arm 18 holds a thread path 20 at its outer end. The second arm 18 is connected to a gear 30 via a shaft 21, which is engaged with a cylinder 31. The cylindrical body 31 is rotatably supported on the projection of the displacement arm 17. Cylinder 3
The upper part 1 is covered by a lid 32, and the shaft fixedly connected to the lid 32 via a connecting piece 33 is driven by the gear 22. This gear 22 is driven by a second planetary gear 23 which is fixedly connected to the disc 12 via a toothed belt 24 (FIG. 1).

FIG. 2 shows the winding device according to FIG. 1 in plan view. As can be seen, the disc 12 is above the ring gear 15 in which the first planetary gear 13 revolves. Similarly, the second driving gear 22
Is recognized. Similarly, the lid 32 of the cylindrical body 31
And a second rotatably supported inside the lid 32
A thread path 20 is rotatably supported by the arm 18. The yarn path 20 is guided into a rail 26 via a grooved sliding piece 25 shown in FIG.

The rotational movement of the drive shaft 11 is transmitted to the first planetary gear 13 via the disk 12. Internal gear 1
The orbital movement of the first planetary gear 13 in 5 is converted into a linear movement of the thread path 20 along the rail 26 via the displacement arm 17. The yarn path 20 is then subjected to additional acceleration via the rotationally driven second arm 18. By a suitable choice of the gear ratio of the gears 13, 23 and 30, the desired speed of the linear movement of the yarn path 20 can be set. Since the part of the winding device to be lubricated, such as the drive shaft 11, is far away from the yarn path 20, the winding device according to the invention has no risk of thread contamination.
