Abstract

PURPOSE:To perform the drawing of a yarn doubling out of the side of a take-up package and its separation to each constituent yarn forming the yarn doubling in an easy manner by holding the constituent yarn so far left in a paralleled state at each constituent yarn, separating holding points to each other in the rectangular direction orthogonal with the drawing direction of the yarn doubling, and separating the yarn doubling into each constituent yarn. CONSTITUTION:Each yarn doubling 2 drawn out of a take-up package 1 is taken out along a hourglass guide 3 constricted in the center, and slightly bent at the outlet side of the guide 3 and each constituent yarn, 2a, 2b, constituting the yarn doubling 2 is paralleled in line. Next, the constituent yarns 2a, 2b kept in this paralleled state are held by clamps 5, 6 individually at each constituent yarn, 2a, 2b, and holding points are separated to each other in the rectangular direction to the drawing direction of the yarn doubling 2, whereby the yarn doubling 2 is separated into these constituent yarns 2a, 2b.

Description

[Detailed Description of the Invention] (Occupational Field of Use) This Kouma is known for
This invention relates to a method of separating each component thread.

K Conventional technology In a doubling machine, after the yarn is cut, the yarn is spliced by connecting the cut end of the doubling yarn wound into the package and the yarn glue pulled out from the yarn feeding package to a drawn state. ζ is connected to each other using an air splicer, nonta, etc.

When using this conventional method, if one of the yarns pulled out from the yarn supply package in an aligned state is cut and the other yarn is not cut, the other yarn that has not been cut is also cut. In addition, because the cut end of the doubled thread is simply tied to the cut end of the thread that has been pulled out in the aligned state, the knots become large and easily noticeable, causing the product to deteriorate over time. This could be a drawback.

Therefore, by separating the yarn end of the winding package which has been first spun into its constituent yarns and tying them separately to the yarns pulled out from the yarn supplying package, the position of the knotted portion is shifted.
Attempts have also been made to make knots small and inconspicuous to prevent defects from occurring, and attempts have also been made to automate this process, but it is particularly difficult to separate the yarn ends on the winding package side after the yarn has been doubled, so complete automation is not possible. has not been done yet.

SUMMARY OF THE INVENTION The present invention has been made with the object of providing a simple method for separating a doubled yarn on the winding package side into each constituent yarn.

Means for Solving the Problem The component yarns constituting the doubling yarn are arranged in parallel, the component yarns placed in a drawn state are gripped separately for each component yarn, and the gripping points are separated from each other in a direction perpendicular to the direction in which the doubling yarns are pulled out. , the doubling yarn is separated into each component yarn.

K-Function] The doubled yarn on the winding package side can be separated into constituent yarns forming the doubled yarn, and each constituent yarn and the cut end of the supply package can be spliced separately.

K implementation example) Hereinafter, the present invention will be described in detail with reference to the drawings.

In the first embodiment shown in FIGS. 1 and 2, a guide 3
, 4 are provided at intervals, between which guides 3, 4 are provided.
Clamps 5.6 are provided for separately clamping each structure J2a, 2b of the doubling yarn 2 drawn on the top of the clamp 4. Reference numeral 7 denotes a suction mouth that sucks the cut end of the doubling yarn 2 wound onto the winding package 1 and pulls it out into an unwound state.

As shown in FIG. 4, the clamps 5 and 6 are moved forward and backward by the operation of air cylinders 8 and 9.
11, and the tips of the air chucks 10 and 11 are provided with fingers 12 and 13 that can be opened and closed, respectively.

Further, the guides 3 and 4 have a narrow, constricted central portion in the shape of a drum, and the doubling yarn 2 pulled out from the winding package 1 is pulled out along the guide 3, and is slightly bent at the exit side of the guide 3. The constituent threads 2a and 2b of the doubling thread 2 which are bent and placed on the guide are arranged in parallel and aligned between the guides 3 and 4.

Now, as shown in Fig. 1, when the doubling yarn 2 wound on the winding package breaks for some reason, the suction mouth 7 is rotated by a signal from a detection device (not shown). Then, the cut end of the doubled yarn 2 wound on the winding package 1 is suctioned, pulled out, and placed on the guide 3 with the constituent yarns 2a and 2b of the doubled yarn 2 aligned. The guide 3 is slightly bent at the exit side so that the component yarns 2a and 2b of the doubling yarn 2 are arranged in parallel, and then placed on the guide 4 so that they are aligned on the guides 3 and 4. Next, as shown in FIG. 2, the clamp 5.6 is moved forward by the operation of the air cylinder 8.9, and the fingers 12 and 13 at the tips of the clamp 5.6 pull the component threads 2a and 2b of the doubling thread 2, which are in the pulled state 11, respectively. At the same time, the doubling thread 2 is cut by a cutter (IN, not shown) at an arbitrary position between the clamp 6 and the suction machining machine 9. At the same time, the clamps 5 and 6 are held together as shown in FIG. When returning to the old position, the constituent threads 2a of the doubling threads 2.

2b is held by the fingers 12, 13 of the clamps 5, 6, respectively, and can be pulled apart and separated into threads 2a, 2b.

Note that the cutting system on the suction mouth 9 side is removed by suction by the suction force of the suction mouth 9 and disposed of as waste thread.

However, in the case of Example 1, the constituent yarns 2a of the doubling yarn 2,
2b was sometimes separated only into a 0-shape but not completely separated into two.

Therefore, in the second embodiment shown in FIGS. 5 to 8, between the guides 3 and 4 described in the first embodiment,
The clamps 5 and 6 also connect the guide 3 and the clamp 5,
Suction nozzles 14 and 15 are inserted between the two. Other than that, the configuration is exactly the same as that of the first embodiment. Therefore, the same parts as in Example 1 are given the same numbers.

The suction nozzle 14.45 is attached to a holder 18 to which a suction pipe 16.17 is fixed, as shown in FIG.
．． 19 is fixed to the cylinder shaft 22.23 of the air cylinder 20.21, and the suction pipe 16.17 can be moved back and forth by the operation of the air cylinder 20.21.

Now, as shown in Fig. 5, when the doubling yarn 2 wound on the winding package breaks due to some reason,
As in the case of the embodiment, the suction mouth 7 rotates to suction and pull out the cut end of the doubling yarn 2 that has been wound around the winding package 1, and the respective components constituting the doubling yarn 2 are removed. Thread 2
A and 2b are aligned and placed on guides 3 and 4. Next, as shown in FIG. 6, the clamps 5 and 6 are moved forward by the operation of the air cylinder 8.9, and the fingers 12.13 at their tips separate the component threads 2a and 2b of the doubling thread 2, which are in the aligned state, respectively. At the same time, as shown in FIG.
0.21, and the doubling thread 2 is cut at an arbitrary position between the clamp 6 and the suction mouth 7 by a cutter (not shown). Then, as shown in FIG.
When the clamps 5 and 6 are returned to their old positions, the constituent yarns 2a and 2b of the doubling yarn 2 are respectively inserted into the suction nozzle 1.
4.15 is sucked into the suction vibe 16.17,
When the suction nozzles 14, 15 are then returned to their original positions, the thread 2a is removed even more reliably and completely than in the first embodiment.

2b.

Note that, as in the first embodiment, the cut thread on the suction mouth 7 side is removed by suction by the suction force of the suction mouth 7 and disposed of as waste thread.

If the above-mentioned 1. When the doubling yarns 2 that were aligned in the second embodiment did not separate properly into the component yarns 2a and 2b, or when the component yarns 2a and 2
When both of the threads b are suctioned and held by one of the suction nozzles 14 and 15, the clamps 5 and 6 repeat the clamping of the constituent threads 2a and 2b of the doubling thread 2, and the constituent threads 2a and 2b are moved to the constituent threads 2a and 2b. separation and gripping by both suction nozzles 14 and 15.

Note that in the second embodiment, the suction nozzle 14
．． 15 has been described as being provided between the guide 3 and the clamp 5.6, but it may also be provided between the clamps 5, 6 and the guide 4.
Although it is most appropriate to hold the threads a and 2b separately, it is of course possible to hold the fluff of the constituent yarns 2a and 2b in the same way.

Furthermore, the suction nozzle 14 in the second embodiment.
15, prepare a separate clamp and attach the component thread 2 of doubling thread 2.
It is also possible to grip a and 2b separately.

K Effects of the Invention This invention draws out the doubled yarn pulled out from the winding package along a drum-shaped guide with a narrow constriction in the center, and bends the guide slightly on the exit side to form the doubled yarn. The component yarns are arranged in parallel, the component yarns placed in a drawn state are gripped separately for each component yarn, and the gripping points are separated from each other in a direction perpendicular to the pulling direction of the doubling yarns, and the doubling yarns are separated into each configuration. Since the yarn is separated into yarns, it is possible to easily pull out the doubled yarn from the winding package and separate it into the constituent yarns forming the doubled yarn using an extremely simple device. The splice between the cut yarn end on the take-up package side and the cut end on the supply package side can also be carried out by shifting the knots for each component yarn using an air splicer, knock, etc., and as a result, the knots It is possible to make it small and inconspicuous and prevent the occurrence of defects, and it can greatly contribute to the complete automation of yarn splicing in yarn doubling machines and the like.
