[Action]

 The line shaft is driven and rotated by the drive means provided at the machine frame end of the spinning device, and the roller that constitutes the fluff suppressing device together with the nip member is pressed against the line shaft to rotate. Further, the rotation of the line shaft is transmitted to the nip member side through an appropriate drive transmission means such as a round belt, so that the nip member is driven at a constant speed ratio with the roller. Then, when the spun yarn introduced from the upstream side to the fluff suppressing device is nipped by the roller and the nip member, false twisting and rubbing action are given, so that the fluff on the spun yarn surface is caught in the yarn itself. It is sent out as spun yarn that is virtually fluff free. When the roller is replaced due to wear of the roller, the roller is removed from the support member while the pressure contact of the roller with the line shaft is released, and parts of the roller are replaced or re-polishing is performed.

Mainly configured, the endless belt 15 of the nip member obliquely contacts the peripheral surface of the roller 12 and drives the endless belt 15 and the roller 12 to feed the spun yarn Y while nipping the spun yarn Y, It is equipped with a mechanism that gives false twisting and rubbing action to the yarn Y.

The roller 12 is formed by fitting a rubber roller 12b onto a metal sleeve 12a, and is freely rotatable via a bearing 12c on a support shaft 10a fixed to the tip of a support arm (support member) 10. Supported by. The support arm 10 is swingably supported at its base by a support shaft 17 projecting from the side of the frame 16, and a spring 18 is provided between the frame 16 and the support arm 10 so as to be wound around the support shaft 17. It The support arm 10 is urged downward in the drawing by the spring 18, and the roller 12 rotatably cantilevered at the tip of the support arm 10 is pressed against the line shaft 11.

The line shaft 11 is provided for each span having 6 to 8 weights of the spinning machine 2 as one span, and by connecting the respective end portions to each other, the line shaft 11 is provided over the entire weight of the spinning machine 2. It is driven by drive means (not shown) provided in an end box at the machine frame end of the spinning machine 2. Further, a pulley 21 for transmitting drive to the drive pulley 13 side is fixed to the line shaft 11.

The drive pulley 13 is a flanged pulley in which flanges 13 a and 13 b are formed on the outer peripheral edges of the endless belt 15 to prevent the endless belt 15 from deviating. The collar 13 a on the yarn sending side of the endless belt 15 is a yarn introducing side. It has a larger diameter than the collar 13b. This is to prevent the endless belt 15 from easily coming off to the yarn feeding side due to contact with the roller 12 which is driven and rotated. The drive pulley 13 is rotatably supported by the support member 19, and is fixed by a screw 20 to one end of a rotating shaft (not shown) which fixes the pulley 23 to the other end. A round belt 22 is stretched between the pulley 23 and the pulley 21.

In addition, in the second embodiment of the present invention shown in FIGS. 3A and 3B, the round belt 22 is not directly stretched between the pulley 21 and the pulley 23, but each pulley 21, The pulley 2 is supported by a pair of idle pulleys 31, 32, 33, and 34, which are attached to the coil 23 at twisted positions, and the round belt 22 is rotatably supported. 1 and 23 are pressed against each other with an appropriate contact length.

The roller 12 is rotatably provided on the frame 16 and is rotated by being pressed against the line shaft 11 by the support arm 10 urged downward by the spring 18 in the figure.

The rotation of the line shaft 11 is transmitted to the drive pulley 13 via the pulley 21, the round belt 22, the pulley 23, and a rotation shaft (not shown). The roller 12 is driven at a constant speed ratio with the roller 12 while being obliquely contacted with the peripheral surface thereof.

In the spinning machine 2 shown in FIG. 1, the sliver S supplied from the can 3 is drafted by the draft device 4 and then false twisted by the air spinning device 5 to be spun yarn Y from the delivery roller 6. Sent out. Many fluffs are formed on the surface of the spun yarn Y in this state by the air action during spinning. Further, the spun yarn Y sent out from the delivery roller 6 is guided by the yarn guide piece 29 in the fluff suppressing device 1 and comes into contact with the roller 12 and the roller 12 in the direction of the arrow 30 in the drawing. The spun yarn Y is fed while being nipped by the endless belt 15 that is being driven. At this time, the spun yarn Y is given a false twisting and rubbing action, whereby the fluff on the surface of the spun yarn Y is caught in the yarn itself. The spun yarn Y having substantially no fluff is sent out to the downstream side, passed through the yarn clearer 8 and wound into a package P in a winding device 9.

When the roller 12 is worn, the roller 12 is removed from the support shaft 10a of the support arm 10 together with the bearing 12c, and the rubber roller 12b is removed from the sleeve 12a and replaced with a new one. 12b may be re-polished. Further, the bolts 28 are removed, the holders 19 and 24 are removed from the brackets 27, the contact state of the endless belt 15 with the roller 12 is released, and then the support arm 10 is splashed upward against the elastic force of the spring 18. If the roller 12 is lifted to release the pressure contact of the roller 12 with the line shaft 11, the rubber roller 12b can be replaced without stopping the line shaft 11.

At this time, in the apparatus of the first embodiment shown in FIG. 2, it is necessary to remove the round belt 22 prior to the work, but in the apparatus of the second embodiment shown in FIG. When 9 is removed, the round belt 22 is simultaneously removed from the pulley 23 and the driving of the endless belt 15 is stopped, so that the work is extremely easy. Instead of providing the pulleys 21, 23, the round belt 22 and the idle pulleys 31, 32, 33, 34, a plurality of conical friction wheels are provided between the rotary shaft of the drive pulley 13 and the lie shaft 11. Can obtain the same effect.
