Abstract

PURPOSE:To surely separate a yarn at the time of ending by constituting a device of a feeler, provided opposedly to a yarn guide passage before a rewinding package, and a yarn separating member, positioned before the feeler, and stopping the rewinding package when a yarn separation signal is generated. CONSTITUTION:A yarn guide member 1, formed with a yarn guide passage 2, is provided before a rewinding package P, and a feeler, consisting of a light projector 3 and light receiver 4, is provided in a lower part of the passage 2 further with clamps 5 to 8 provided in a before side successively to the passage 2. The larger is a degree of overlapping two yarns the smaller a degree of spreading light of the light receiver 4 is decreased, when the two yarns are separated, spread of the light is increased, and a yarn separation signal is generated by assuming the two yarns separated when a degree of this spread of light is in the predetermined or more. Being based on this yarn separation signal, upper part clamps 5, 7 are lowered to hold each yarn between lower part clamps 6, 8, and the left side clamps 5, 6 and the right side clamps 7, 8 are paired and moved to right and left simultaneously with the package P 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 and winds two yarns or 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 have been unwound in a doubled state from a patch stand are separated individually and sent to a splicing device. The threads are fed in and 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 can nip the thread, if it's thick, you won't know, and if it's thin, it will come off while you're 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 during splicing when two yarns are combined and wound onto a take-up reversing cage.

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:
Feelers 3 and 4 are provided facing the yarn guide path 2 in front of the winding package P and detect that two yarns are separated during yarn splicing and issue a yarn separation signal. It consists of yarn separating members 5 to 8 or IO which separate the separated yarns in response to a yarn separation signal, and stops the winding package when the yarn separation signal is issued.

[For production]

In the yarn separating device configured as described above, when the slab catcher senses a yarn breakage or a yarn defect, and the suction mouth 9 suctions the yarn end on the package side and turns toward the yarn splicing device, each The yarn is guided into a yarn guide path 2. Then, the feelers 3 and 4 search for the separated parts of each yarn, and when the feelers 3 and 4 locate the separated parts, the feelers 3 and 4
emits a thread separation signal. As a result, the thread separating member 5~
8 or 10 acts on the separated part of the thread and the thread is separated. The winding package also stops at the same time as the yarn separation signal is issued.

〔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 suctioned 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 FIGS. 1 and 2.

On the front side of the winding package P, a yarn guide member 1 having a relatively wide yarn guide path 2 formed in its upper part is provided, and a feeler consisting of a light emitter 3 and a light receiver 4 is provided at the bottom of the yarn guide path 2. It is set up. Furthermore, clamps 5, 6, 7, and 8 are provided on the front side of the thread guide member 1 following the thread guide passage 2.

The light projector 3 projects light from below the yarn guided to the yarn guide path 2, and the light receiver 4 receives the reflected light and determines the degree to which the two yarns overlap. In other words, the larger the degree of overlap between the two threads, the smaller the spread of the received light, and if the two threads are separated, the larger the spread of the light. Applying this principle, when the spread of the received light exceeds a predetermined value, it is determined that the two threads are separated and a thread separation signal is issued.As will be described later, A command is issued to the clamps 5, 6, 7, and 8 based on this thread separation signal. At the same time, the winding bucket P is stopped.

As shown in FIG. 1, four clamps 5, 6, 7, and 8 are provided on the left, right, top, and bottom. Usually, the lower clamps 6 and 8 are in contact with each other, and the upper clamps 5 and 7 are in contact with the lower clamps 6 and 8. The clamps 5 and 7 are separated above the clamps 8 and are waiting in a state where they are in contact with each other. However, when the light receiver 4 issues a thread separation signal, the upper clamps 5 and 7 descend and the lower clamp 6
, 8, and then the left clamp 5
, 6 and the right-hand clamps 7 and 8 form a pair and move left and right. The clamps 5, 6, 7, and 8 are preferably made of an elastic material such as rubber in order to securely grip the thread.

In addition, instead of separating the threads using the clamps 5, 6, 7, and 8, a twenty-one dollar separator 10 having a twenty-one dollar tip facing upward as shown in FIG. 2 is used, and this is controlled by the yarn separation signal. It may be raised to separate the threads. At this time as well, there is no difference in that the winding package P is stopped at the same time as the yarn separation signal.

As mentioned above, when the slub 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. is guided to the thread guide path 2. Then, the emitter 3 and receiver 4 locate the separated portion of the yarn, and the clamps 5, 6, 7, 8 or the 21 dollar seberator 10 separate the yarns further. At the same time, the winding package P 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 yarn separation devices, the system does not rely solely on extremely delicate yarn nips caused by mechanical members, but uses a feeler to find the separation of the yarn and then separates the separated portion, which is reliable and simple. The two threads can be separated.
