Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to bunch winding in a thread winding machine, particularly a contact friction drive type thread winding machine using friction rollers.

Bunch winding of bobbins is essential for continuous post-processing of synthetic fibers that require post-processing such as false twisting.

As shown in FIG. 1, one of the bunch winding devices described above moves a thread shifting lever 1 in both the axial direction of the bobbin shaft 2 and the direction perpendicular to the axial direction at the same time, and removes the thread from the traverse guide G and winds the bunch. There is a device in which thread shifting to the winding W is performed simultaneously using a thread shifting lever 1. Each bobbin B1, B2, B is attached to the thread shifting lever 1.
3.Protrusions T1, T2, T3, T4 corresponding to B4
is provided, and the yarn removed by the traverse guide G is brought to the right bunch winding position W by the projection.

When the bunch winding W is completed, the thread shifting lever 1 moves to the left toward the position shown in the figure, and at this time, the threads of each bobbin are placed at the center of each bobbin B1, B2, B3, and B4 on the delivery roller. Therefore, when the thread shifting lever 1 returns, the thread of each bobbin returns to the center position of each bobbin, is automatically picked up by the traverse guide G of each bobbin, and thread traverse is started.

Therefore, the conventional device described above is a bunch winding device suitable for the case where the godet roller and the bobbin shaft 2 are parallel.

However, as shown in FIG. 2, the bobbin shaft 2 and the godet rollers 3, 4, 5 may be arranged at right angles to each other due to the type of yarn to be handled, the installation relationship between the spinning nozzle and the winding machine, etc.

Furthermore, due to the requirements of post-processes such as stretching and false twisting, as well as doffing, the bobbin B is made into a disk shape with a short width.
It is a normal configuration of a spinning winding machine that a plurality of (four in the figure) are supported on one bobbin shaft 2.

In the device as shown in FIG.
The bunch winding device can be used as is by providing a thread separation position of each godet roller and setting it at the center of each bobbin B1, B2, B3, B4. However, as the number of godet rollers increases, the machine becomes more complex, and there are drawbacks such as the quality of the yarn wound on each bobbin being slightly different due to the arrangement thereof.

It is also conceivable to provide a thread guide corresponding to the central position of each bobbin after the godet roller 5, but undrawn thread has particularly unstable properties and it is extremely undesirable to pass the thread through such a thread guide.

Normally, the thread is divided into a plurality of bobbins by a thread guide 8 directly below the oiling rollers 6, 7, with the aid of oil lubrication.

For various reasons as mentioned above, in the one shown in FIG.
2, the thread is guided from the godet roller 5 to the bobbins B3 and B4.

In this case, the thread separation point of the godet roller 4 is set between the bobbins B1 and B2, and the thread separation point of the godet roller 5 is set between the bobbins B3 and B4, that is, at the butt part of the two bobbins.
In the figure, when the thread shifting lever 1 returns from the bunch winding position, the thread returns for bobbins B2 and B4 and is picked up by the traverse guide of each bobbin, but for bobbin B1,
As for B3, it does not return and therefore it is impossible to shift to yarn traverse.

The present invention is aimed at solving the above-mentioned drawbacks, and will be described in detail below with reference to FIGS. 2 to 4.

In Figs. 1 and 2, a plurality of (four in the figure) bobbins B1, B2, B3, B4 are arranged on the bobbin shaft 2.
are supported with their ends abutting each other. The bobbin B is brought into surface contact with the friction roller 9 and is driven by friction. Reference numeral 10 denotes a traverse cam box, and the box 10 is provided with traverse guides G1, G2, G3, G4 corresponding to each bobbin B1.

The traverse cam box 10 and the friction roller 9 are arranged in one movable bracket 11.
On the other hand, the bobbin shaft 2 is fixed in position, so that the traverse cam box 10 and the friction roller 9 are moved in accordance with the winding of the yarn layer on the bobbin.

The thread shifting lever 1 is mounted on slide pieces 14 and 15 which are slidably and rotatably fitted into the guide tube 12. It is constructed as an extending bar, and is provided with thread shifting protrusions T1, T2, T3, T4 corresponding to each bobbin B1. It is located at the bobbin end (the left end of each bobbin in FIG. 3).

First, at the beginning of winding, turn the thread outer lever 27 and place it at the chain line position 27a in FIG.
3. Hang friction roller 9 and bobbin B on D4.
Winding of each thread onto each bobbin is started by winding the end of the thread onto bobbin B through the gap.

After this, when the thread outside lever 27 is returned to the position shown by the solid line in Fig. 4, each recess D1, D2, D3, and D4 will be automatically picked up by each traverse guide G1, G2, G3, and G4, and the initial winding will be performed on each bobbin. administered.

After this, the piston 19 is advanced, and the thread shifting lever 1 is advanced and turned to the chain line 1a in FIG. 4. By the above-mentioned turning of the thread shifting lever 1, each thread is moved to the thread outer lever 27.

Moving to E4, the thread shifting lever 1 is advanced in the axial direction, and is hooked onto the protrusions T1, T2, T3, and T4, and brought to the bunch winding position at each bobbin end, and the bunch winding W1,
W2, W3, and W4 are performed.

While the thread shifting lever 1 is advanced, the bobbins B1 and B3 are
threads are engaged in the recesses 25,26.

After the bunch winding is completed, the piston 19 moves back and the thread shifting lever 1 is returned to the solid line position in FIG. The threads of bobbins B1 and B3 return to the recess 2.
5, 26, and eventually the threads of all the bobbins follow the return of the thread shifting lever 1 and return all at once to each traverse guide G1, G2, G3, G.

As described above, in the present invention, the thread shifting lever 1 simultaneously removes the thread from the traverse guide and shifts the thread to the bunch winding position, so bunch winding can be performed without causing stick winding, and the recesses 25 and 26 are provided. As a result, even if the thread does not run over the center position of the bobbin, it is possible to move from bunch winding to regular traverse without any problem.
