Description

[Detailed explanation of the idea] 〓Industrial application field〓 This invention relates to a two-nozzle type spinning device.

〓Conventional technology〓 In a so-called two-nozzle type spinning device in which a pair of air jet nozzles are arranged in parallel for a draft device of one spindle, the joining point of the spun yarn is provided upstream of the delivery roller. In order to align the yarns that still have untwisting torque, the remaining torque causes the yarns to loosen, which has the advantage of preventing separation of both yarns in the subsequent process.

However, when this method is used, the above-mentioned yarn doubling point moves further upstream, or multiple doubling points occur, and the yarn exiting the nozzle is not fully untwisted. A phenomenon was observed in which the threads were doubled and the strength of the threads was significantly reduced.

〓Problems to be solved by the invention〓 In the untwisting process in a two-nozzle spinning device, the movement of the yarn doubling point and the occurrence of multiple yarn doubling points are prevented,
The purpose is to double the yarn after the yarn has been sufficiently untwisted.

〓Means for solving the problem〓 In a two-nozzle type spinning device in which a pair of air jet nozzles are provided in parallel for one draft device, a doubling guide is provided at a position directly above the delivery roller, and the above-mentioned A yarn separation guide running parallel to each other was provided between the air jet nozzle and the yarn doubling guide.

〓Effect〓 The separation guide provided between the air injection nozzle and the yarn doubling guide separates the yarns running in parallel from each other,
Prevents twisting of the same yarn, movement of the yarn doubling point, and occurrence of multiple yarn doubling points.

〓Example〓 Embodiments of this invention will be described below with reference to the drawings.

In FIG. 1 showing a first embodiment of this invention, 1 is a two-nozzle type spinning device of this invention, in which a pair of air injection nozzles 3a and 3b are connected to a nozzle support 4 for one draft device 2. are arranged parallel to each other on the top. The draft device 3 is
Two non-twisted fiber bundles 5a supplied in parallel,
5b to a specified thickness,
Bat crawler pair 6a, 6b, apron 7a, 7b
It consists of a pair of middle rollers 8a, 8b, and a pair of front rollers 9a, 9b. Inside the air injection nozzles 3a and 3b (not shown),
It is provided with a nozzle that blows out a compressed air flow in the direction of movement of the fiber bundles 5a and 5b. Further, a gutter-like dust collector 10 is attached to the nozzle support 4, and a first dust collector 10 standing upright from the bottom is installed at an intermediate position.
The separation guide 11 is further provided with an opening 12 on the bottom of the tip.
are provided respectively. A suction pipe 13 is provided in the opening 12.
is connected to generate a suction airflow to prepare for suction removal of fly fluff, fluff, and other fibrous debris generated on the dust collector 10. and the dust collector 1
The tip of 0 is connected to a pair of delivery rollers 16a, 16 via a doubling guide 15 equipped with a second separating guide 14.
facing b.

Therefore, the two fiber bundles 5a and 5b supplied in parallel to the drafting device 2 pass through the drafting device 2 and the air injection nozzles 3a and 3b, respectively, and then form threads 17a and 17b to be sent to the dust collector. 10, separated by a first separation guide 11 and a second separation guide 14, move while being prevented from interlocking with each other, and are pulled together by a doubling guide 15 in an aligned state, and a pair of delivery rollers 16a,
While being nipped by 16b, it is actively sent out and wound up into a package (not shown).
Then, the generated fluff and other fiber waste are removed from the opening 1.
2 into the suction pipe 13.

Next, in the second embodiment shown in FIG.
A cutter 20 consisting of a fixed blade 18 provided on the first separation guide 11 in the first embodiment and a movable blade 19 positioned close to the fixed blade 18 and meshing with the fixed blade 18 is provided, and the cutter 20 is provided with a cutter 20, When a defective portion occurs in the slab or the like in 17b, the yarn is cut and removed, and other configurations are no different from the first embodiment. Therefore, the same parts are given the same numbers.

In each of the above embodiments, in order to eliminate the tension between the yarns 17a and 17b, and to eliminate the movement of the yarn doubling point and the occurrence of multiple yarn doubling points, the first separation guide 11 is provided on the dust collector, and the Although the second separation guide 14 has been described as being provided on the guide 15, a plate-shaped separate guide may be provided on the dust collector 10 to separate the threads 17a, 17b in parallel to the running direction of the threads 17a, 17b. Of course,
The key point is the thread 17 coming out from the air injection nozzles 3a and 3b.
Until a and 17b reach the doubling guide 15,
The remaining torque from untwisting causes them to tighten each other,
Any structure may be used as long as it can prevent the yarn doubling point from moving or the occurrence of multiple yarn doubling points.

= Effect of the invention = As described in detail above, the two-nozzle type spinning device of the present invention is a two-nozzle type spinning device in which a pair of air jet nozzles are arranged in parallel for one draft device. A yarn doubling guide is provided directly above the yarn doubling guide, and a yarn separating guide is provided between the air jet nozzle and the yarn doubling guide that runs parallel to each other, so the yarn doubling guide passes through the air jet nozzle. Even if residual torque exists, the two threads running parallel to each other are isolated from each other by the presence of the separation guide, and as a result, the threads do not sag each other.
In addition, the doubling point may be moved by the separation guide,
There is no risk of multiple doubling points occurring, and the yarns are untwisted and then doubled, so each yarn can be twisted one at a time.
Extremely strong twin threads can be easily obtained without reducing the strength of the main thread.
