Abstract

PURPOSE:To surely separate yarns at the time of ending by constituting a device of a guide block provided before a rewinding package, feelers provided in the vicinity of each end part of a needle guide groove provided in this guide block and needles of making a motion along the concerned needle guide groove. CONSTITUTION:Needles 3, 4 are normally separated from each other to right and left and positioned in the upper of a needle guide groove 2, but when a signal of ending is generated, the two needles 3, 4 are moved to the inside to approach each other along the groove 2, next lowered together and placed in the groove 2. Thereafter, both the needles are moved in a direction of separating from each other to right and left in the groove 2 and again lifted when both the needles arrive at end parts of the groove 2. This motion is repeatedly performed from now on. When the needles 3, 4 are moved to the end parts of the groove 2 by hooking a yarn through a motion mentioned in the above, the yarn is detected by feelers 5, 6, and the motion of the needle and a package P are stopped by generating a yarn separation signal with the two yarns assumed to separate when the yarn is detected by both the two feelers 5, 6.

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 and winds two yarns or a spinning machine that takes up two yarns.
The present invention relates to a device for separating two threads.

[Conventional technology]

Conventionally, when splicing two yarns together and winding them around a winding package, the yarns are separated from the package and unwound individually and sent to a splicing device as single yarns. 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 were able to nip the thread, if it is a thick thread, you will not know about it, and if it is a thin thread, it will come off while you are moving it.
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.

mouth. Structure 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:
Winding: A guide block l provided in front of the package P and having a needle guide groove 2 parallel to the axis of the package P, and a guide block l provided near each end of the needle guide groove 2 to detect the thread when the thread is detected. Feelers 5 and 6 that issue a separation signal, and needles 3 and 4 that repeat the movements of approaching and descending along the needle guide groove 2, separating in the needle guide groove 2, and rising until they issue a yarn separation signal during yarn splicing. Thus, the winding package P is stopped at the same time as the yarn separation signal.

[For production]

In the yarn separating device configured as described above, when the slab catcher senses a yarn breakage or detects a yarn defect, and the suction mouth 9 suctions the yarn end on the package side and turns toward the yarn splicing device, the second Dollars 3 and 4 are feelers 5 and 6
The movements of approaching along the needle guide groove 2, descending, moving away from the needle guide groove 2, and rising are repeated until the needle generates a yarn separation signal. The two threads are separated and sent to fillers 5 and 6.
When the yarn separation signal is issued, the winding package P also stops.

〔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) sucks 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 9 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 FIG.

A guide plate 7, feelers 5 and 6, a guide block 1, needles 3 and 4, and a guide plate 8 are provided in this order on the front side of the winding package P.

The guide plate 7 and the guide plate '8 are for guiding the yarn when the suction mouth 9 sucks the yarn end on the package P side and turns.

The guide block 1 has a needle guide groove 2 formed in its upper surface parallel to the axis of the package P, and guides the tips of the needles 3 and 4 along the needle guide groove 2.

The needles 3 and 4 are normally located above the needle guide groove 2 apart from each other left and right, but when a yarn splicing signal is issued, the two needles 3 and 4 move along the needle guide groove 2. They move inward until they touch each other, and then descend together and enter the needle guide groove 2. Thereafter, both move in the needle guide groove 2 in a direction that leaves each other left and right, and reach the end of the needle guide groove 2. Then, both of them rise again.From now on, repeat this exercise.

The feelers 5 and 6 detect the thread when the thread is caught and moved to the end of the needle guide groove 2 by the above-described movement of the needles 3 and 4.
When both threads are detected, a thread separation signal is issued as the two threads are separated, and the movement of the above-mentioned 21 do/l/3 and 4 is stopped.

When the yarn separation signal is issued, the winding package P
I also try to stop it. In this embodiment, the feelers 5 and 6 are provided in front of the needle guide groove 2, but they may also be provided in the rear thereof.

As mentioned above, when the slub catcher senses a yarn breakage or detects a yarn defect, the suction mouth 7 sucks the yarn end of the package P side which is being rewound, and inserts it into the yarn splicing device. The yarn is guided along guide plates 7 and guide plates 8. Immediately after that, the needles 3 and 4 approach and descend along the 21-torcaide groove 2, and move away from and rise in the 21-torcaide groove 2, and the feelers 5 and 6 detect the yarn and send a yarn separation signal. Repeat until uttered. At the same time as the yarn separation signal is issued, the winding package P also stops.

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

In other words, unlike conventional thread separation devices, two threads can be separated reliably and easily because there is no need for a very delicate thread nip caused by a mechanical member.

FIG. 1 is a schematic perspective view of the thread separation device.
