Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This invention relates to a pneumatic spinning device.

[0002]

[Prior Art]

 In the conventional pneumatic spinning device, as shown in FIG. 2, the sliver S pulled out from the can 1 is introduced into the draft device 5 through the guides 2, 3 and the trumpet guide 4, drafted by the draft device 5, The yarn Y is twisted by a spinning nozzle 6 to form a yarn Y, which is wound by a winding device 10 via a delivery roller 9 provided in a bending portion 8 of a yarn path on the front surface of a downstream side spinning machine base 7. Then, the delivery roller 9 nips and sends out the spun yarn Y, and also contacts other parts on the spinning machine base 7, for example, a knotter (not shown) provided between the delivery roller 9 and the winding device 10. It also has the function of guiding the thread so as to prevent it.

In this device, since the yarn Y is traversed by the winding device 10, as the distance between the winding device 10 and the delivery roller 9 is increased, the damage to the yarn Y is reduced, and the yarn Y is good with less fluff. Yarn can be obtained. However, if the space between the winding device 10 and the delivery roller 9 is simply expanded, the height of the entire spinning device becomes high, and maintenance of the draft device 5 and the pneumatic spinning nozzle 6 is difficult.

[0004]

[Problems to be solved by the device]

 The present invention aims to obtain a good quality yarn with less fluff without increasing the size of the entire spinning device.

[0005]

[Means for Solving the Problems]

 It is equipped with a draft device, a spinning device and a winding device, and the yarn path is inclined between the draft device and the spinning step part, and is bent between the spinning device and the winding device so as to be substantially vertical on the downstream side of the draft device and the spinning device. A delivery roller for pulling out the yarn is provided upstream of the bending portion of the yarn path, and a guide roller that positively rotates is provided at the bending portion of the yarn path.

[0006]

[Action]

 By providing the delivery roller on the upstream side of the bent portion of the yarn path, it is possible to expand the space between the delivery roller and the winding device without increasing the height of the entire spinning device, and to increase the nip point of the yarn and the winding device. Since the space between the machine and the traverse guide can be widened, fluctuations in the tension of the yarn due to traverse motion are reduced, and by providing a guide roller at the bend of the yarn path, the yarn is not The contact with other parts is prevented, and the positive rotation of the guide roller reduces friction with the yarn to prevent generation of fluff.

[0007]

【Example】

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

The pneumatic spinning device of the present invention is the same as the conventional pneumatic spinning device except that the position of the delivery roller is different from the conventional one and the guide roller is provided. Therefore, in FIG. 1 showing an embodiment of the present invention, the same parts as those in FIG. 2 showing a conventional pneumatic spinning device are designated by the same reference numerals.

That is, the pneumatic spinning device of the present invention comprises a trumpet guide 4, a back roller pair 5a, a middle roller pair 5b, and a front roller pair 5c on the spinning machine stand 7 from the back of the machine stand toward the front. A draft device 5 and an air spinning nozzle (spinning means) 6 are arranged adjacent to each other in series and inclined. A winding device 10 for the yarn Y is provided below the front surface of the machine base. Due to the positional relationship between these devices 5 and 10 and the air spinning nozzle 6, the yarn path Ya is inclined at the draft device 5 and the air spinning nozzle 6 portion and is substantially vertical on the downstream side thereof. And the take-up device 10 are bent. On the upstream side of the bent portion 8 of the yarn path Ya, a delivery roller 9 is provided close to the yarn outlet of the air spinning nozzle 6. Further, the bent portion 8 is provided with a guide roller 11 that positively rotates. The rotation speed of the guide roller 11 is equal to the rotation speed of the delivery roller 9. In the figure, reference numeral 12 denotes a traverse guide, which is supported by a traverse bar (not shown) and reciprocates in the direction perpendicular to the paper surface in FIG. 1 to traverse the yarn Y.

Therefore, in the present invention, the delivery roller 9 is arranged close to the yarn outlet of the air spinning nozzle 6 as shown in FIG. 1, and the positively rotating guide roller 11 is the yarn on the front surface of the spinning machine stand 7 downstream of the delivery roller 9. The sliver S, which is provided on the curved portion 8 of the road and pulled out from the can 1, forms the yarn Y by the guides 2, 3, the trumpet guide 4, the draft device 5, and the air spinning nozzle 6, and the air spinning nozzle 6 After being sequentially fed while being nipped by the delivery roller 9 arranged in close proximity, the yarn path is bent while contacting the peripheral surface of the actively rotating guide roller 11 provided at the bending portion 8 of the thread path on the front surface of the spinning machine stand 7. Then, the package 14 is wound on the bobbin 13 of the winding device 10 while forming the package 14. The guide roller 11 also serves to guide the yarn so as not to come into contact with other parts on the spinning machine base 7, for example, a knotter (not shown) provided between the guide roller 11 and the winding device 10. There is.

Since the delivery roller 9 is provided on the upstream side of the bent portion 8 of the yarn path Ya as described above, the height of the entire spinning device is increased as compared with the case where the delivery roller 9 is provided in the bent portion 8 (FIG. 2). Therefore, the space between the delivery roller 9 and the winding device 10 can be expanded. As a result, the distance between the traverse position of the winding device 10 and the nick point of the yarn of the delivery roller 9 becomes larger than before, so that the tension fluctuation of the yarn due to the traverse movement is reduced, and even the yarn with less strength is used. Since the yarn breakage does not occur and the guide roller 11 positioned downstream of the delivery roller 9 positively rotates, friction with the yarn does not occur and fluffing of the yarn is reduced to obtain a high quality yarn. be able to.

[Effect of the device]

 As described in detail above, the pneumatic spinning device of the present invention comprises a draft device, a spinning device and a winding device, and the yarn path is inclined at the draft device and the spinning device portion and is substantially vertical on the downstream side thereof. A delivery roller that bends between the spinning means and the winding device to draw out the yarn is provided upstream of the bending portion of the yarn path, and a guide roller that positively rotates is provided at the bending portion of the yarn path. It is possible to expand the space between the delivery roller and the winding device without increasing the height of the entire spinning device, and as a result, the distance between the traverse position of the winding device 10 and the yarn nip point of the delivery roller 9 is increased. Since it is larger than before, thread tension fluctuation due to traverse motion is reduced, thread breakage does not occur even with less strong thread, and a guide roller is provided at the bending portion of the thread path. As a result, the yarn is prevented from coming into contact with other parts on the spinning device, and the guide roller 11 located downstream of the delivery roller 9 is positively rotated, so that friction with the yarn does not occur and the yarn becomes fluffy. It is possible to obtain a yarn of good quality by reducing
