First, as shown in FIG. 1, FIG. 7, the string Y which is radiated and continuously supplied is wound on the bobbin B at the winding position Wp while being advanced by the vane traverse device 16 and package P It becomes During winding, the bobbin holder 11 at the winding position Wp rotates, and the contact roller 13 rotates in contact with the package P being wound to control the rotation of the bobbin holder 11 and at the same time to take up the winding diameter. The slide box 14 is raised with increasing.

When this winding package P is wound up as shown in FIG. 3, the turret plate 12 shown in FIG. 1 rotates, and the bobbin B of the standby position Sp turns into the winding position Wp. Move, and the full take-up package P moves to the standby position Sp as indicated by the trajectory L, the slide box 14 descends, and the contact roller 13 and the bobbin bin B Contact. Subsequently, as shown in FIG. 4, the threading guide 33 advances to the thread line Y side, and peels the thread Y from the traverse apparatus 16. FIG.

That is, as illustrated in FIG. 2, the rod 38 of the retracting cylinder 37 extends, the connecting rod 36 moves in the left direction of the drawing, and the threading guide 33 passes through the link mechanism 35. Advances to the position (25P) indicated by the dashed-dotted line.

Until the threading guide 33 advances and the string Y is peeled off from the traverse device 16, the thread Y is in the traverse range T and at the same time the thread guide 44 and the thread guide guide ( 46).

In this state, when the thread guide cylinder 48 is elongated, the thread guide guide 46 moves, so that the string Y in the traverse range T is caught by the thread guide guide 45, and finally pulls the thread. It will be captured between the guide 44 and the thread guide guide (45).

In this state, the thread Y is out of the traverse range T and is in the position of the thread hook part S of the bobbin B. As shown in FIG.

In this state, the proximity switch 50 described in FIG. 2 operates, the threading guide 33 retreats, and the string Y is bent toward the traverse device 16 as shown in FIG. As shown in Fig. 6, the thread string Y is held in close contact with the thread catching portion 44a of the thread pulling guide 44 in a state of being captured by the thread guide guide 45, the thread pulling guide 44, or the like. have.

Subsequently, due to the operation of the thread movement guide of the lower thread guide device 21a, the thread string Y is caught by the thread hanger portion S of the gongbobin B, and the thread connected to the full winding package P is tensioned. It is cut | disconnected and isolate | separated from the string Y of the bobbin bin B. As shown to FIG.

After that, when the thread guide cylinder 48 degenerates and the thread guide guide 45 retreats, the thread Y moves along with the retraction of the thread guide guide 45. When the threaded portion 44a slides and moves while sliding, the thread guide guide 45 is separated from the thread pull guide 44, the thread string is released from the thread catching portion 44a, and the thread line Y immediately becomes a traverse device ( 16) is captured and stiffened, and the string Y of the new bobbin B is wound.

The thread stripping guide 33, the thread pulling guide, and the thread guide guide 45 are located on one side rear with respect to the thread passage being wound, and are provided on the traverse device 16 side, and the opposite side, which is the front of the thread passage, is an open space. (open space). For this reason, work can be easily performed at the time of thread hanging and maintenance work.

In addition, after the thread is caught in the thread hanger portion S of the bobbin, when the thread is moved into the traverse range, the thread pulling guide 44 guides the thread passage during thread winding to the traverse device 16 side. , Since the thread guide guide 45 is located on the traverse device 16 side with respect to the thread passage being wound, the thread is guided when the thread is pulled away from the thread pulling guide 44 by the traverse device 16. It does not interfere with (45), and the winding thread is not broken. In addition, as shown in Fig. 6, the thread pulling guide 44 is capable of finely adjusting the installation position in the axial direction of the thread cutting guide 25 by the long hole 55, It is possible to make a fine adjustment of the forward and backward movement in the traverse direction, to adjust the range of the spiral portion formed when transitioning to the original winding after forming the bunching winding in the thread hook portion S, and cutting the spiral portion later. It becomes easy to form.

Since the thread pulling guide 44 and the thread guide guide 45 are configured to retreat in a direction orthogonal to the traverse direction in conjunction with the thread pulling guide 33, for the thread pulling guide 44 or the thread guide guide. As for (45), there is no need to provide means for separately driving in that direction, and the operation control of the guide is also simplified. In the above-described embodiment, the threading guide 33 is provided close to the traverse device 16. However, the close guide 33 is advantageous in terms of compactness, and the fine passage can be easily adjusted.

In the above-described embodiment, the slide box with the contact rollers and the like rises as the package diameter increases, but the box with the contact rollers and the like is fixed and the turret plate rotates with the increase in the package diameter. good.

This apparatus can be used not only for the thread wrapping from the full package to the empty package illustrated in the above embodiment, but also for the thread hanger, so that the apparatus can be applied to a spin winder instead of the automatic switching method.

As described above, according to the present invention, since a traverse device, a threading guide, and the like are concentrated on one side of the thread passage, and the other side of the thread passage is an open space, it is easy to perform maintenance work or thread hook work. . In addition, since the thread guide guide and the thread pulling guide are arranged to be completely pushed on one side of the thread passage without crossing the thread passage, the above-mentioned thread guide guide and the thread pulling guide interfere with the thread hook work. It will not be possible.
