Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a fluff suppressing device which is a spun yarn processing device.

[0002]

[Prior art]

 Conventionally, in an air spinning machine, for example, a sliver supplied from a can is drafted by a draft device composed of a pair of draft rollers of 3 to 5 lines, and then, by an air spinning device provided on the downstream side of the draft device. It was false twist spinning. On the surface of the spun yarn obtained by such an air spinning device, many fluffs were formed by the air action during spinning, which had a considerable influence on the quality of the product.

[0003]

[Problems to be solved by the device]

 In view of these points of the conventional technique, the present invention has an object to provide a fluff suppressing device that can obtain a spun yarn that is substantially free of fluff, and that is compact and has a simple structure. is there.

[0004]

[Means for Solving the Problems]

 It is composed of a touch roller and an endless belt that obliquely contacts the touch roller and nips the yarn. One of a pair of pulleys on which the endless belt is mounted is located outside the one end surface of the touch roller. I was prepared to do.

[0005]

[Action]

 When the spun yarn introduced into the fluff suppressing device from the upstream side is nipped by the touch roller and the endless belt, false twisting and rubbing action are given, and the fluff on the spun yarn surface is substantially caught in the yarn itself. It is sent out as fluff-free spun yarn. Since one of the pair of pulleys on which the endless belt is mounted is located outside the one end surface of the touch roller, even if the pulley is installed close to the touch roller, the endless belt is Since the contact pressure with the touch roller can be sufficiently secured, it is possible to reduce the size of the fluff suppressing device itself, and thereby, between the weights of various textile machines such as spinning machines arranged in parallel. It is easy to attach to a restricted attachment site.

【Example】

 An example of the embodiment will be described with reference to the drawings.

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.

2 and 3, the fluff suppressing device 1 includes a touch roller 12 that is driven to rotate, and an endless member that is obliquely contacted with the touch roller 12 and is mounted between a drive pulley 13 and a driven pulley 14. The belt 15 is mainly configured to have a mechanism for feeding the spun yarn Y while nipping it with the endless belt 15 and the touch roller 12, and providing the spun yarn Y with false twisting and rubbing operations.

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 deviating, 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. Further, the collar 13b on the yarn introducing side is held to the thickness of the endless belt 15 in order to avoid contact with the touch roller 12. The drive pulley 13 is fixed to one end of a rotary shaft 26 rotatably supported by a supporting member 18 with a screw 19, and the supporting member 18 is bolted to a bracket 11 fixed to a frame 10 with a bolt 16. It is fixed at 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 3c of the drive pulley 13 is located outside the one end surface 12a of the touch roller 12, and at the lower end 13d of the drive pulley 13, the endless belt 15 is the contact surface between the belt 15 and the touch roller 12. It is supported on the lower surface than t.

As a result, the endless belt 15 mounted between the drive pulley 13 and the driven pulley 14 is brought into pressure contact with the touch roller 12 at the contact surface t by an appropriate contact pressure, and the lower end 13 d of the drive pulley 13 is pressed. It is possible to dispose the drive pulley 13 close to the touch roller 12 while avoiding the contact of the collar 13b with the outer peripheral surface of the touch roller 12 in FIG.

A bevel gear 27 is formed on the other end of the rotary shaft 26, and the bevel gear 27 meshes with a bevel gear 29 formed on a rotary shaft 28 of a friction roller 20 rotatably supported by the support member 18. Further, the friction roller 20 is in pressure contact with the roller 22 provided on the drive shaft 21 of the touch roller 12, so that the drive shaft 21 is rotated by the roller 22, the friction roller 20, the rotary shaft 28, and the pair of rollers. It is transmitted to the drive pulley 13 via the bevel gears 29, 27 and the rotating shaft 26, and the endless belt 15 is driven by the drive pulley 13 at a constant speed ratio with the touch roller 12.

The driven pulley 14 is rotatably supported by a support shaft 24 provided on the support member 23, and the support member 23 is fixed to the support member 18 by a bolt (not shown). A thread guide piece 25 is provided on the lower surface of the support member 23 so as to hang down.

Next, the operation will be described based on examples.

The spun yarn Yo sent out from the delivery roller 6 is guided by the yarn guide piece 25 and comes into contact with the touch roller 12 and the touch roller 12 and is driven in the direction of arrow 26 on the contact surface. The yarn is sent while being nipped with the belt 15. At this time, the spun yarn Yo is given a false twisting and rubbing action, so that the fluff on the surface of the spun yarn Yo is caught in the yarn itself and the spinning is substantially fluff-free. The yarn Y is sent to the downstream side.

Further, by locating the drive pulley 13 outside the one end surface 12 a of the touch roller 12, the drive pulley 13 can be brought close to the touch roller 12 and the device itself can be reduced in the width direction. Since a sufficient distance is provided between the friction roller 20 and the friction roller 20, the pair of bevel gears can drive and rotate the drive pulley 13 with a relatively simple drive transmission structure. This ensures a sufficient contact pressure with a simple structure in a limited mounting space.

In the above embodiment, 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 It can be applied to various textile machines such as machines and winders that are effective in suppressing fluff.

[0019]

[Effect of device]

 As described above, the fluff suppressing device of the present invention comprises the touch roller and the endless belt that obliquely contacts the touch roller and nips the yarn, and one of the pair of pulleys on which the endless belt is mounted is Since it is provided outside the one end surface of the touch roller, it is possible to obtain a spun yarn that is substantially free of fluff, and because it is compact and simple in structure, a large number of fluff suppressing devices are arranged in parallel. It can be installed in the limited space between each spindle of the spinning machine.
