FIG. 1 shows a spinning machine 2 provided with a fluff suppressing device 1 of the present invention. In FIG. 1, a spinning machine 2 includes a trumpet guide 3, a back roller pair 4a, a third roller pair 4b, a second roller pair 4c on which an apron belt 4e is mounted, and a front roller pair 4d. 5, a delivery roller 6 in pressure contact with the nip roller 6a 6, a fluff suppressing device 1, a slack tube 7, a yarn clearer 8 for detecting a yarn defect, and a winding device 9 are sequentially arranged from the upstream side to the downstream side. The sliver S supplied from the can is bundled by the trumpet guide 3, drafted by the draft device 4, then false twisted by the air spinning device 5, and the spun yarn Yo sent from the delivery roller 9 is In the winding device 9, the traverse guide 9 is used as the spun yarn Y whose fluff is suppressed by passing through the fluff suppressing device 1. By while traversing, in pressure contact with the actively the rotating winding drum 9b are supported by the rotary self standing on the cradle arm 9c bobbin is wound as a package P.

The fluff suppressing device 1 is fixed to the tip of a frame 10 supporting a drive shaft 6b of the delivery roller 6 on the downstream side of the delivery roller 6 of the spinning machine 2 via a bracket 11, The fluff suppressing device 1 will be described below with reference to the drawings.

The fluff suppressing device 1 according to the first embodiment of the present invention shown in FIG. 2 is a pair of driving rotary elements, and a touch roller 12 fixed to a drive shaft 21 and an oblique contact with the touch roller 12. , The endless belt 15 mounted between the drive pulley 13 and the driven pulley 14 is used, and when the spun yarn Y is sent while nipping the spun yarn Y with the endless belt 15 and the touch roller 12, It is equipped with a mechanism that provides false twisting and rubbing.

The drive pulley 13 is a pulley with a collar formed with collars 13a and 13b on the outer peripheral edges thereof respectively to prevent the endless belt 15 from departing, and the collar 13a on the yarn sending side of the endless belt 15 is a yarn introducing side. It has a larger diameter than the brim 13b. This is because the endless belt 15 is likely to come off to the yarn delivery side due to contact with the drivingly rotating touch roller 12. The drive pulley 13 is fixed to one end of a rotary shaft 28, which is rotatably supported by a supporting member 18 also serving as a gear box, with a screw 19, and the supporting member 18 is fixed to the frame 10 with bolts 16. The bracket 11 is fixed to the bracket 11 with bolts 17.

At this time, the relative positional relationship between the drive pulley 13 and the touch roller 12 is as follows. That is, the rotation center line 13c of the drive pulley 13 is located outside the one end surface 12a of the touch roller 12, and the endless belt 15 between the belt 15 and the touch roller 12 is located on the nip side (tension side) of the drive pulley 13. It is supported below the contact surface.

As a result, the endless belt 15 mounted between the drive pulley 13 and the driven pulley 14 is pressed against the touch roller 12 at the contact surface by appropriate contact pressure, and at the nip side of the drive pulley 13. It is possible to dispose the drive pulley 13 close to the touch roller 12 and obliquely while avoiding the contact of the collar 13b with the outer peripheral surface of the touch roller 12.

A bevel gear 27 is formed at the other end of the rotary shaft 28. The bevel gear 27 meshes with a bevel gear 26 integral with a rotary shaft 25 of a pulley 24 rotatably supported by the support member 18, Further, a drive transmission belt 23 is mounted between the pulley 24 and the pulley 22 provided on the drive shaft 21 of the touch roller 12.

The driven pulley 14 is rotatably supported by a support shaft 29 provided on the support member 20, and the support member 20 is fixed to the support member 18 by a bolt (not shown). A thread guide piece 30 is provided on the lower surface of the support member 18.

A fluff suppressing device 201 according to a second embodiment of the present invention shown in FIG. 3 is a pair of drive rotary elements that obliquely contact each other and send out a yarn while nipping the yarn. Similarly, the touch roller 12 fixed to the drive shaft 21 and the endless belt 15 mounted between the drive pulley 213 and the driven pulley 214 are used, but in the fluff suppressing device 1 of the first embodiment, The drive pulley 13 and the driven pulley 14 are arranged on the downstream side of the touch roller 12 in the rotational axis direction, and the endless belt 15 is driven and rotated by the downstream drive pulley 13, while the fluff of the second embodiment is used. In the suppressing device 201, the drive pulley 213 is arranged on the upstream side in the rotation direction of the touch roller 12, and the driven pulley 214 is arranged on the downstream side, and the endless belt 15 is arranged by the drive pulley 213 on the upstream side. It is driven and rotated.

The driven pulley 213 is fixed by a screw 19 to one end of a rotary shaft 228 rotatably supported by a support member 218 which also serves as a gear box, and a bevel gear 227 is formed at the other end of the rotary shaft 228. Has been done. The bevel gear 227 is rotatably supported by the support member 218, meshes with a bevel gear 226 that is integral with the rotary shaft 225 of the pulley 24, and further includes the pulley 22 and the pulley 22 provided on the drive shaft 21 of the touch roller 12. A drive transmission belt 223 is mounted between them.

Next, the operation will be described based on examples.

In the spinning machine 2 shown in FIG. 1, the sliver S supplied from a can (not shown) is focused by the trampet guide 3, drafted by the drafting device 4, and then false twisted by the air spinning device 5, and then delivered by the delivery roller. 6 is sent out as spun yarn Yo. Many fluffs are formed on the surface of the spun yarn Yo in this state by the action of air during spinning. The spun yarn Yo sent from the delivery roller 6 is composed of the touch roller 12 in the fluff suppressing device 1 and the endless belt 15 that is in contact with the touch roller 12 and is driven in the direction of the arrow 31 on the contact surface. At the same time, the spun yarn Yo is sent out while being nipped, and the spun yarn Yo is given a false twisting and rubbing action, whereby the fluff on the surface of the spun yarn Yo is caught in the yarn itself and becomes a spun yarn Y having substantially no fluff. It is sent to the downstream side, passed through the yarn clearer 8 and wound up as a package P by the winding device 9.

In each of the fluff suppressing devices 1 and 201 shown in FIGS. 2 and 3, the touch roller 12 is directly driven and rotated by a drive shaft 21 connected to a power source (not shown). The rotation of the drive shaft 21 is performed by the pulley 22, the drive transmission belt 23 (223), the pulley 24 (224), the rotary shaft 25 (225), the pair of bevel gears 26, 27 (226, 227), the rotary shaft 28 (228). Is transmitted to the drive pulley 13 (213) via the drive pulley 13 (213), so that the endless belt 15 mounted between the drive pulley 13 (213) and the driven pulley 14 (214) moves at a constant speed with the touch roller 12. It is driven in a ratio.

The contact pressure between the endless belt 15 and the touch roller 12 is set by the mounting state of the bracket 11 to the frame 10, and the contact pressure is used for suppressing the fluff of the spun yarn Y in the fluff suppressing devices 1 and 201 of the present invention. Since it is extremely important, when assembling the fluff suppressing devices 1 and 201, it is first necessary to fix the bracket 11 to the frame 10 so that the contact pressure becomes an optimum value. Although the distance between the pulley 22 and the pulley 24 (224) is also changed by changing the mounting state of the bracket 11 to the frame 10, it is mounted between the pair of pulleys 22, 24 (224). Since the belt tension of the drive transmission belt 23 (223) can be appropriately adjusted later, the contact pressure of the endless belt 15 with respect to the touch roller 12 can be set to an optimum value without impairing the drive transmission. Adjustment and maintenance are extremely easy.

The case where the touch roller 12 and the endless belt 15 are used as the pair of driving rotary elements constituting the fluff suppressing device 1 (201) has been described. It is also possible to use a pair of endless belts. Further, in the above-described embodiment, an example is shown in which the fluff suppressing device 1 of the present invention is applied to the spinning machine 2 having the air spinning device 5, but the present invention is not limited to this, and other spinning machines and winders. It can be applied to various textile machines for which the suppression of equal fluff is effective.
