Abstract

PURPOSE:To surely separate yarns at the time of ending by providing constitution of feelers, which are provided in right and left before a rewinding package, and a screw roller which is provided before the feelers and formed with threads in directions different in each side with the central part bordered. CONSTITUTION:In a process in which a yarn end in a side of a package P, while it is rewound back by sensing a yarn cut and detecting a yarn defect by a slub catcher, is sucked by a suction mouth 7 and introduced to an ending device, each yarn is guided parts 5, 6 of a yarn traversing member 4. Thereafter, the member 4 slowly traverses. When the two yarns are separated by this action, the respective yarn is separated to right and left to ride on a thread of a screw roller 3. The separated yarn is brought into contact with feelers 1, 2 to generate an electric signal. When the electric signals are simultaneously generated, a rewinding package driving motor Mp and a motor Ms for driving the screw roller 3 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 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 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:
There are feelers 1 and 2 installed on the left and right sides in front of the winding package P to detect the yarn, and in front of the feelers 1 and 2, screws in different directions are formed in the center of the winding package. When the feelers 1 and 2 simultaneously issue thread detection signals,
This is to stop the winding package drive motor Mp and the screw roller 3 drive motor Ms.

[For production]

In the yarn separating device configured as described above, when the slub catcher senses a yarn breakage or a yarn defect, and the suction mouth sucks the yarn end on the package side and turns toward the yarn splicing device, the screw roller 3 rotates, and the two threads ride on the screws on each side of the Neshi roller 3 and are separated to the left and right. The separated yarn acts on feelers 1 and 2, and a yarn detection signal is generated. When the signals are issued at the same time, the winding package drive motor Mp and the screw roller 3 drive motor Ms 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, the 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, and the yarn ends are rotated together and introduced into the yarn splicing device (not shown). Ru. 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.

Feelers 1 and 2 are provided on the left and right sides of the front side of the winding package P, respectively. Further in front of this, a screw roller 3 is provided. A yarn swinging member 4 having guide portions 5 and 6 at the front and rear of the yarn path is provided so as to sandwich the feelers 1 and 2 and the screw roller 3.

The feelers 1 and 2 emit electrical signals when the thread comes into contact with them.

On the surface of the screw roller 3, screws are formed in different directions with the center as a boundary, so that when it rotates as shown by the arrow in FIG. 1, the thread moves toward the end of the screw roller 3. There is. In this case, the left side of the screw roller 3 is a right-handed screw, and the right side is a left-handed screw. The depth and spacing of the threads are as shown in Figure 2, where d is the diameter of the thread.
The depth of the screw threads is d to 2d, and the spacing is d or less.

As mentioned above, the slub catcher detects a yarn breakage or a yarn defect, and in the process of suctioning the yarn end of the package P side that is being rewound using the suction mouth 7 and introducing it into the yarn splicing device, each yarn is is guided by the guide portions 5 and 6 of the thread swinging member 4. After that, the thread swinging member 4 slowly traverses. When the two threads are separated by this action, each thread rides on the screw of the screw roller 3 and separates to the left and right. Then, the separated threads touch feelers 1 and 2,
Emit an electrical signal. When the electric signals are emitted at the same time, the motor Mp for driving the winding package and the motor Ms for driving the screw roller 3 are stopped.

If either feeler 1 or 2 works, it means that the two threads are stuck together, so a single signal will not stop each motor.

C. Effect of the invention Since this 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.
