Abstract

(57) [Abstract] [Purpose] The yarn supplied from the air-spinning nozzle is provided with a fluff suppressing device arranged on the yarn path on the downstream side of the roller, thereby reducing the fluff of the spun yarn obtained by the air-spinning device and performing high-quality spinning. To obtain a spun yarn processing device capable of obtaining a yarn. A fluff suppressing device including a delivery roller that is positively driven and a driven roller that is arranged in contact with the delivery roller with its shaft inclined obliquely is provided on the yarn path on the downstream side of the delivery roller for the yarn supplied from the air spinning nozzle. The yarn introduced into the contact surfaces of both rollers of the fluff suppressing device is fed while giving a false twisting action.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a spun yarn processing device obtained by an air spinning device.

[0002]

[Prior art]

 A conventional spinning device includes a draft device for drafting a sliver supplied from a can, an air spinning nozzle (false twisting device) for twisting the sliver drafted by the draft device, and a nip roller for delivering the formed yarn. The delivery roller includes a delivery roller and a winding device that winds the delivered yarn. The spun yarn is formed between the air spinning nozzle and the delivery roller, and then wound by the winding device. Many fluffs were formed on the surface of the conventional spun yarn thus obtained, which had a considerable influence on the quality of the product.

[0003]

[Problems to be solved by the device]

 This invention is to reduce the fluff of the spun yarn obtained by the air spinning device by using the fluff suppressing device arranged on the yarn path on the downstream side of the delivery roller for the yarn supplied from the air spinning nozzle to obtain a spun yarn of good quality. The purpose is to obtain a processing device for spun yarn that is capable of

[0004]

[Means for Solving the Problems]

 A fluff suppressing device is provided on the yarn path on the downstream side of the delivery roller for the yarn supplied from the air-spinning nozzle, the delivering roller being positively driven and a driven roller having a shaft obliquely in contact with the delivery roller and being in contact with the delivery roller. The yarn introduced into the contact surface of both rollers of the machine is sent out while giving false twisting action.

[0005]

[Action]

 The fluff generated on the yarn surface is wound around the core yarn to reduce the fluff.

【Example】

 Embodiments of the present invention will be described below with reference to the drawings.

As shown in FIG. 1, a spinning device including a spun yarn processing device of the present invention includes a back roller pair 1a, a third roller pair 1b, a second roller pair 1c mounted with an apron band, and a front roller. A drafting device 1 composed of a pair 1d, an air spinning nozzle 2 for twisting a sliver S drafted by the drafting device 1, and a delivery roller 3 comprising a nip roller 3a for delivering the formed yarn Y and a delivery roller 3b, and It comprises a fluff suppressing device 4 located on the downstream side and a winding device 5 for winding the yarn Y sent out from the fluff suppressing device 4, 6 is a dust collector equipped with a suction pipe 7, 8 is a slack tube, 9 Is a slab catcher, and 10 is a traverse device of the winding device 5.

The air-spinning nozzle 2 is composed of a first nozzle and a second nozzle that cause swirl flows in opposite directions to act on the yarn. The yarn exiting the air-spinning nozzle 2 is a bundled spun yarn that is basically composed of core fibers (core yarns) that are aligned substantially parallel to each other and wrapping fibers that are spirally wound around the core fibers.

However, in the present invention, as described above, the fluff suppressing device 4 is provided on the yarn path on the downstream side of the feeding roller 3 for the yarn Y supplied from the air spinning nozzle 2, and the fluff suppressing device 4 is provided. As shown in FIGS. 2 and 3, the delivery roller 11 having a rubber coating 11a on its surface, which is positively driven by a drive device (not shown), is disposed in contact with the delivery roller 11 with its shaft obliquely inclined. The driven roller 12 is made of rubber and is introduced between the rubber coating 11a of the delivery roller 11 and the driven roller 12 to give a false twisting and twisting action to the yarn, while maintaining the same speed as the delivery roller. Or the yarn is delivered at a slightly faster speed.

Since the driven roller 12 needs to be in line contact with the delivery roller 11, the driven roller 12 has a drum shape, and the crossing angle θ of the driven roller 12 with the delivery roller 11 is set to 15 to 75 degrees so that the driven roller 12 is in contact with the delivery roller 11 while straddling the delivery roller 11. It is arranged and can be contacted and separated by the arm rod 13. The delivery roller 11 may have a smooth surface as shown in FIG. 4, but when the fluff control device 4 is used, the delivery roller 11 is applied to the thread introduced between the rubber coating 11 a of the delivery roller 11 and the driven roller 12. Since a thrust force that tends to move to the left is applied, a drum with diagonal streaks 14 on the surface as shown in FIG. 5 or a drum with diagonal streaks 15 on the surface as shown in FIG. The shape is preferable because it can prevent the yarn from being offset.

In the above embodiment, as shown in FIG. 3, the driven roller 12 is arranged so as to intersect the axial direction of the delivery roller 11 in the axial direction from the upper left to the lower right. However, the yarn Y can be twisted in the opposite direction when the yarn Y intersects with the axis of the delivery roller from the upper right to the lower left.

The yarn Y that is being spun now runs while being ballooned (untwisted) between the air spinning nozzle 2 and the delivery roller 3, and is then delivered from the delivery roller 3 to provide a fluff suppressing device. 4, the yarn Y is given a false twist and a fluff holding action between the driven roller 12 and the delivery roller 11, and the fluff 16 on the yarn Y is wound around the core yarn 17 as shown in FIG. That is, the yarn Y having no fluff is formed.

[0013]

[Effect of device]

 As described in detail above, the present invention is directed to a delivery roller that is positively driven and a driven roller that is arranged in contact with the delivery roller by inclining its shaft obliquely on the yarn path on the downstream side of the delivery roller of the yarn supplied from the air spinning nozzle. The fluff suppressing device is provided to feed the yarn introduced into the contact surfaces of both rollers of the fluff suppressing device while giving false twisting action to the yarn. Therefore, the balloon is provided between the air spinning nozzle and the feeding roller. While the yarn is running, it is introduced into the fluff suppressing device having the above-mentioned configuration, and a false twisting action is given between the driven roller and the delivery roller, and the fluff on the yarn easily winds around the core yarn and has no fluff. It was possible to obtain spun yarn of excellent quality.
