Further, in this embodiment, a displacement sensor 30 and a movable machine 4 interlocked with the displacement sensor 30 are attached to the lower end 29 of the suction mouse 22.
1131 is provided. This displacement sensor 30 is
It is configured to check the distance of the yarn feeding package P from the surface of the yarn layer, and when the outer diameter of the yarn feeding package P changes, the movable fl[31 is driven to move the yarn feeding package P. By moving in the transverse direction B of the path S, the distance between the suction mouth 22 and the yarn supply package P is maintained at a predetermined pressure Ud that allows suction.

The yarn end guide means 23 is held in the upper part of the suction mouth 22 via a bracket 32 near the yarn path of the yarn @Y to be pulled out, and has a lever member 33 that is rotatably provided. When the lever member 33 is driven to rotate, the lever member 33 pulls the thread sY with its tip, and the protruding veg 21
The thread path is changed so as to engage the side portion 34 of the thread.

The package rotation means 24 is formed of a drive roller 35 that contacts the circumferential surfaces of the rays 1 to T, and a drive motor 36 that rotates the drive roller 35 in forward and reverse directions.

When the lever member 33 is rotated, the drive roller 35
It is designed to rotate in sync with this. The rotation direction C is opposite to the winding direction of the yarn supply package P. That is, the yarn feeding package P is rotated several times in a direction such that the yarn end Y is wound around the yarn layer, and the pulled out yarn end Y is wound around the circumferential surface of the protruding beg 21. ing. Also, suction mouse 2
When 2 sucks the yarn @Y, the yarn feeding package P is rotated in the direction in which the yarn is released (the same direction as the winding direction), and the yarn is pulled out together.

The cutter means 25 is supported by a bracket 32 above the yarn end guide means 23 at a predetermined distance from the top hole 37 of the protruding beg 21, and is attached to yarns arranged in parallel so as to cross the yarn path. It is formed with an end guide plate 38 and a cutter 39 provided therebetween. And the protruding beg 21
The thread end Y is cut at the timing when the thread end Y is wound around the thread end Y.

The suction pipe 26 is provided coaxially with the protruding beg 21,

along the central hole 27 of No. 1.

Furthermore, in addition to this, a light wave preventing member 4o is provided to prevent the wound yarn end Y from being released. The light wave preventing member 40 is made of a plate having a predetermined width,
It is supported by the suction mouth 22 so as to be able to rotate substantially horizontally. When the yarn end Y is wound around the protruding beg 21, it is turned and comes into contact with the circumferential surface of the protruding beg 21.

Further, the transfer path S is formed by two belt conveyors 41, and the suction pipe 26 can be placed between them. Positioning rollers 42 and 43 are provided on the opposite side of the drive roller 35 with the belt conveyor 41 in between. After being stopped at the position, it turns and comes into contact with the circumferential surface of the tray T.

Next, the operation of this embodiment will be explained.

The yarn feeding package P moves on the transfer path S and reaches a predetermined value (i[
When the positioning roller 42°113 is stopped at the second
The package is rotated to the position shown by the solid line in the figure, comes into contact with the tray T, and is rotated around the axis A by the drive of the package rotation means 24. Following this rotation, the suction mouth 22 separates the yarn end Y from the yarn layer, pulls it out obliquely upward, and engages the yarn end guide plate 38 of the cutter means 25. At this time, the position of the suction mouse 22 is
0 and the movable m-ellipse 31, the suction is finely adjusted according to the outer diameter of the yarn supply package P.

When the yarn 1y is pulled out, the yarn end guide means 23
Turn counterclockwise in the figure to cross the yarn path and engage the yarn end Y with the side portion 34 of the protruding beg 21. At this time, the drive roller 35 of the package rotating means 24 starts rotating in the opposite direction to that at the time of taking out the package. The yarn end Y has a shape in which the yarn supply package p@ is restrained, and according to this rotation (direction C), it takes on a substantially conical shape and turns around the axis A. That is, as shown in FIG. 4, while being pulled back from the upper side of the suction mouth 22, it is wound helically around the circumferential surface of the protruding beg 21.

After being wrapped a predetermined number of times, the light wave passes through the prevention member 40.
comes into contact with the upper circumferential surface of the protruding beg 21 and blocks the suction mouth 22 from the upper part of the yarn end Y that is not wound. That is, when the yarn end guide means 23 is turned back to its original position, the winding is prevented from being released by the upward suction air of the suction mouth 22.

Then, the cutter means 25 cuts the upper part of the wound yarn @Y. The suction pipe 26 causes the cut yarn end Y to hang down from the upper end of the ceiling hole 37 by a downward air flow, as shown by the dashed line in FIG.

The yarn supply balance gauge P whose yarn end Y has been processed is sent to an automatic winder. Then, the yarn end Y is unwound and sent to the suction vibrator of the automatic winder as shown by the two-dot chain line in FIG. It is subjected to a rewinding process.

In this way, since the yarn end Y is wound around the protruding veg 21 and further suspended into the center hole 27, the yarn guide 5 and a means for blowing up the yarn guide 5 are not required.

Conventionally, the yarn 1 is transferred to the yarn grip 6 of the yarn guide 5.
Il! The lY was locked manually by a worker. For this reason, there was a limit to the processing speed, but according to the present invention, all the processing of the yarn end Y is automatically performed, thereby speeding up the processing of picking out large packages such as dyed bag gauges. In other words, it can contribute to improving the productivity of the rewinding process.

Note that when winding the yarn around the protruding veg 21, the rotation direction of the yarn feeding package P may be such that the yarn @Y is released, as shown in FIG. Simply pulling the yarn end Y by means 23 will not work.
By being sucked by the suction mouth 21,
It is not possible to wrap the thread around the protruding beg 21. Therefore, it is necessary to provide a gripping means 51 at the position of the lever member 33 to restrain the upper part of the thread end Y. By doing so, the yarn end Y is wound around the protruding veg 21 while being pulled out from the yarn supply balance gauge P.

Further, the rotation of the package rotation means 52 may be in one direction, which is released.

Furthermore, as an axle that projects from the yarn supply package P, a center pipe that passes through the yarn supply balance gauge P may be provided as a separate body, without using the protrusion beg 21 provided on the tray T.

Further, the present invention is also applicable to the case where the yarn feeding package is taken out with the tray T placed sideways.

[Effects of the Invention] In summary, according to the present invention, the following excellent effects are achieved.

A suction mouth for pulling out the yarn end of a yarn supply package having a shaft body, a yarn end guide means for engaging the pulled-out yarn end with a side part of the shaft body, and a package for rotating the yarn supply package axially. Since the present invention is equipped with a rotating means, it is possible to simplify the processing of the leading yarn end of the large package, contributing to speeding up the processing and improving the productivity of the rewinding process.
