Abstract

PURPOSE:To surely perform thread separation by constituting a device of thread separating rollers, which are provided before a rewinding package being overlapped laterally and vertically and rotated at the time of ending to hold fluff of a thread, passing through a space of the rollers, and to separate the thread, and feelers, provided before the thread separating rollers, for detecting the thread. CONSTITUTION:When a thread end in a side of a package P, during being wound back, is sucked by a suction mouth 7 and introduced into a thread ending device by sensing a thread cut and detecting a thread defect by a slub catcher, thread separating rollers 3 to 6 are rotated in a direction of an arrow head, and each thread, passing between the rollers 3, 5, is guided to a space surrounded by the four thread separating rollers. Each thread, whose fluff is put between the rollers 3, 4 or the rollers 5, 6, is dragged in a direction of separating from each other, following rotation of the rollers 3 to 6. The thread traverses a space between feelers 1, 2 to generate an electric signal, when the electric signals are simultaneously generated, the package P and the rollers 3 to 6 are stopped.

Description

[Detailed description of the invention] a. Purpose of the Invention [Field of Industrial Application] This invention provides a method for splicing yarns in a winder that combines two yarns and winds them, or in a spinning machine that winds double yarns.
The present invention relates to a device for separating two threads.

[Conventional technology]

Conventionally, when splicing two yarns together and winding them into a winding package, the yarns that are unwound in the doublet from the package are separated individually and sent to a splicing device in a single yarn state. The threads are spliced separately.

The yarn separation device guides two yarns into a separation space, where each yarn is nipped separately with a mechanical member, and each wheel yarn is separated by moving each mechanical member left and right. be.

[Problem to be solved by the invention]

Conventional yarn separation devices require a very delicate yarn nip using a mechanical member, which is quite difficult. Even if you manage to nip the thread, if it is a thick thread, you will notice it, and if it is a thin thread, it will come off during movement.
It cannot serve its purpose.

SUMMARY OF THE INVENTION An object of the present invention is to provide a yarn separation device that can reliably separate yarns when splicing two yarns together and winding them into a winding package.

Configuration of the Invention [Means for Solving the Problem] In order to achieve the above object, the thread separation device of the present invention has the following features:
The winding package P is stacked horizontally and vertically in front of it,
It has an abacus bead shape with two tapered parts on the circumference.
The tapered portions touch each other to form a gap, and are provided in front of the yarn separation rollers 3, 4, 5, and 6, which rotate during yarn splicing to pinch the fuzz of the yarn passing through the gap and separate each yarn. It consists of feelers 1 and 2 that detect the yarn, and feelers 1 and 2
The winding package and the yarn separation rollers 3, 4, 5, and 6 are stopped when the yarn detection signals are simultaneously generated.

[For production]

In the yarn separation device configured as described above, when the slub catcher senses yarn breakage or yarn defects, and the suction mouth 7 suctions the yarn end on the package side and turns to the yarn splicing device side, the yarn The separation rollers 3, 4, 5, and 6 rotate, each yarn enters the gap surrounded by each separation roller, and the fluff of the yarn is caught between the yarn separation rollers 3, 4, 5, and 6.
As the threads move away from each other. The separated yarn acts on feelers 1 and 2, and a yarn detection signal is generated. When the signals are issued simultaneously, the winding package and yarn separation rollers 3, 4, 5, 6 are stopped.

〔Example〕

In a winder that combines two yarns and winds them, or in a winding device in a spinning machine that takes up two yarns, a slab catcher detects yarn breakage or yarn defects and automatically cuts the running yarn. Then, a suction pipe (not shown) suctions the yarn end on the yarn feeding side, while the yarn end wound around the package P is unwound and sucked by the suction mouth 7 as shown in FIG. The yarn is then introduced into a yarn splicing device (not shown). There, each yarn end is spliced separately.

In order to separately splice the yarns using the splicing device, the yarns must be separated using the yarn separating device.

Next, the thread separation device will be explained with reference to FIGS. 1 and 2.

Two pairs of yarn separation rollers 3 are installed on the front side of the winding package P.
, 4, 5, and 6 are arranged side by side in the left-right direction in a state where they are in contact with each other. Further in front of this, feelers 1 and 2 are provided on the left and right sides.

The feelers 1 and 2 emit electrical signals when a thread enters the gap between them.

The two pairs of yarn separation rollers 3, 4 and 5, 6 have shapes as shown in FIG. That is, they are flat rollers in the shape of an abacus bead with two tapered portions formed on the circumferential surface. Their rotational axes are inclined to each other as shown in FIG. 2, so that the tapered portions of the shaft sides of the yarn separation rollers 3, 4 and yarn separation rollers 5, 6 are in contact with each other. Then, an enclosed rj1 gap is formed that is large enough for two threads to pass through. The yarn guided there removes its fluff by a yarn separation roller 3.
, 4 or between the yarn separation rollers 5 and 6, and as they rotate, the two yarns are dragged away from each other. 5 and 6 are preferably made of an elastic material such as rubber, and the yarn separation rollers 3 and 4 and the yarn separation opening rollers 5 and 6 are preferably pressed against each other lightly.

As mentioned above, when the slab catcher senses a yarn breakage or detects a yarn defect, the suction mouth 7 sucks the package P side yarn end which is being rewound and introduces it into the yarn splicing device, and the yarn separation roller 3 , 4, 5, and 6 rotate in the direction of the arrow in FIG. 1, and each thread is guided through the thread separating rollers 3, 5 into the gap surrounded by the four thread separating rollers. As the yarn separation rollers 3, 4, 5, and 6 rotate, the fluff of each yarn is pinched by the yarn separation rollers 3, 4 or the yarn separation rollers 5, 6, and is dragged away from each other. The thread then crosses the gap between the feelers 1 and 2, and an electrical signal is emitted. When electrical signals are emitted at the same time,
The winding package P and the yarn separation rollers 3, 4, 5, and 6 are stopped.

If either feeler 1 or 2 works, it means that the two yarns are stuck together or the separation is incomplete, so a single signal will cause the winding package P and yarn separation rollers 3, 4, 5, 6 to Never stop.

C. Effects of the Invention Since the present invention is configured as explained above,
This produces the effects described below.

That is, unlike conventional thread separation devices, two threads can be easily separated without the need for a very delicate thread nip using a mechanical member.

The longer the thread, the more effective it is.
