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 prior art, the present invention can obtain a spun yarn that is substantially free of fluff, can keep the quality of the spun yarn constant, and adjust the assembling. It is an object of the present invention to provide a fluff suppressing device that is easy to remove.

[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 supported by a swingable support member. Further, the biasing member is provided on the supporting member via the rod and the screwing member screwed to the rod.

[0005]

[Action]

 The support member that supports the pulley on which the endless belt is mounted is biased by the biasing member via the rod, so that the endless belt is pressed against the touch roller. 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. The contact pressure of the endless belt with respect to the touch roller is adjusted by changing the relative position of the rod and the biasing member depending on the screwed state of the rod and the screw member screwed to the rod.

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

In FIGS. 2A and 2B, the fluff suppressing device 1 includes a touch roller 12 that is driven to rotate, and an endless belt that is obliquely contacted with the touch roller 12 and is mounted between a drive pulley 13 and a driven pulley 14. The endless belt 15 and the touch roller 12 feed the spun yarn Y while nipping the spun yarn Y to provide a false twisting and rubbing operation to the spun yarn Y.

The drive pulley 13 is fixed to one end of a rotation shaft (not shown) rotatably supported by a support member 18 with a screw 19, and the support member 18 is fixed to the frame 10 by a bolt 16 in a bracket. It is fixed to 11 with a bolt 17.

A bevel gear is formed at the other end of the rotary shaft, and the bevel gear meshes with a bevel gear formed on the rotary shaft of the friction roller 20 rotatably supported by the support member 18, and further, The friction roller 20 is pressed against a roller 22 provided on the drive shaft 21 of the touch roller 12, so that the drive shaft 21 rotates via the roller 22, the friction roller 20, and a pair of bevel gears (not shown). Is transmitted to the driving pulley 13, and the driving pulley 13 drives the endless belt 15 with the touch roller 12 at a constant speed ratio. The contact pressure between the friction roller 20 and the roller 22 is appropriately adjusted by changing the mounting position of the bracket 11 on the frame 10 through the elongated hole 11a formed in the bracket 11.

The driven pulley 14 is rotatably supported by a support shaft 24 provided on the support member 23. The support member 23 is formed by inserting a support shaft 25 projecting parallel to the support shaft 24 on the side surface of the base of the support member 23 into a circular hole 28 formed in a member 27 fixed to the support member 18 by a bolt 26. Thus, the support shaft 25 is swingably supported, and a snap ring 29 is engaged with the support shaft 25 to prevent the support shaft 25 from being pulled out from the circular hole 28.

A rod 31 is swingably supported by a support shaft 30 projecting from a side surface of the support member 23 on the tip side, and the other end of the rod 31 is attached to a support member 18 and a member 27 by a bolt 32. Is inserted into a circular hole 34 formed at the tip of the supporting member 33 fixed by the above, and a washer 37 is interposed between the nut 36 screwed into the screwing portion 35 of the rod 31 and the supporting member 33. 2 is interposed by the spring 38, the rod 38 and the support member 23 interlocking with the rod 31 are urged downward in FIG. 2a, and thereby rotatably supported by the support member 23. The endless belt 15 mounted between the driven pulley 14 and the driving pulley 13 is pressed and brought into pressure contact with the touch roller 12. Then, as shown in FIG. 2B, the thread guide 39 is fixed to the lower surface of the support member 23.

The contact pressure of the endless belt 15 against the touch roller 12 is obtained by rotating the nut 36 screwed into the screw portion 35 of the rod 31 to increase or decrease the amount of protrusion of the rod 31 from the spring 38. Adjusted by.

An air cylinder is provided as a biasing member instead of the spring 38, the rod 31 is biased by the air cylinder to pressurize the endless belt 15, and the air pressure of the air cylinder is adjusted to adjust the endless belt 15. It is also possible to adjust the contact pressure with respect to the touch roller 12.

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 39, touches the touch roller 12, and the endless belt which is driven in the direction of arrow 40 on the contact surface. 15 is sent while being nipped, and at this time, the spun yarn Yo is given a false twisting and rubbing action, whereby the surface of the spun yarn Yo is fluffed and the spun yarn is substantially fluff-free. Y is sent to the downstream side.

The fluff suppressing state of the spun yarn Y is determined by the driving speed of the endless belt 15 and the touch roller 12 and the contact pressure of the endless belt 15 to the touch roller 12, but in the fluff suppressing device 1 of the present invention, the spring is used. Since the endless belt 15 is pressed against the touch roller 12 by the urging force of 38, even if the thickness of the belt 15 is reduced due to friction of the endless belt 15, the contact pressure is always kept constant.

Further, the contact pressure of the endless belt 15 of the fluff suppressing device 1 to the touch roller 12 is irrespective of the attached state of the fluff suppressing device 1 by rotating the nut 36 after the assembly of the fluff suppressing device 1. Since it is also easy to adjust, the contact pressure in each spindle of the spinning machine 2 in which a large number of spinning units shown in FIG. 1 are arranged can be set uniformly. The quality of the spun yarn Y between the weights can be kept uniform.

[0020]

[Effect of device]

 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 as described above. Since the support member is supported by a swingable support member, and the support member is provided with a biasing member via a rod and a screw member that is screwed to the rod, the attachment state of the fluff suppressing device and the belt Since the belt contact pressure can be kept constant regardless of the wear state, the quality of the spun yarn can be kept constant, and the above belt contact pressure can be easily adjusted. When assembled on each weight of the spinning machines arranged in parallel, it is easy to make the fluff suppression state between the weights uniform.
