Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a textile machine equipped with 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.

Therefore, a fluff suppressing device has been developed that feeds the spun yarn while nipping the spun yarn with a touch roller that is driven to rotate to eliminate the fluff of the spun yarn and a belt that obliquely contacts the touch roller. When the suppressing device is provided on each of the spindles arranged side by side in the spinning device, a touch roller for each spindle is provided on a common rotary shaft connected to one drive source, and the endless belt is driven by the rotation of the rotary shaft. If all the weights are driven simultaneously, the drive system will be simplified.However, in such a fluff suppressing device, the fluff suppressing device is driven even with the unspun weight, which is a waste. However, there was a problem that the whole weight had to be stopped even when performing maintenance on the fluff suppressing device for one weight.

[0004]

[Problems to be solved by the device]

 In view of these points of the conventional technique, the present invention can obtain a spun yarn that is substantially free of fluff, can stop the drive of an arbitrary weight, and can be used during machine operation. It is an object of the present invention to provide a fluff suppressing device capable of performing maintenance of a weight.

[0005]

Means for Solving the Problems A fluff suppressing device including a pair of nip members that obliquely contact each other and nips a yarn is provided for each weight, and each fluff suppressing device is provided between the pair of nip members and their drive sources. A clutch was provided for each weight.

[0006]

[Action]

 When the spun yarn introduced into the fluff suppressing device from the upstream side is nipped by a pair of nip members (for example, a touch roller and an endless belt), false twisting and rubbing action are applied, which causes the fluff on the spun yarn surface to occur. It is entangled in itself and delivered as spun yarn that is virtually fluff free. Then, by disengaging the clutch of the fluff suppressing device on any weight and cutting off the transmission of the rotation from the drive shaft to the pair of nip members, the rotation of the drive shaft is not stopped even during machine operation. The maintenance work of the fluff suppressing device of the weight can be performed.

【Example】

 An example of implementation of the present invention will be described with reference to the drawings.

FIG. 1 shows one spindle of a spinning machine 2 equipped with a fluff suppressing device 1. In FIG. 1, the spinning machine 2 is composed of 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. , A delivery roller pressing 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 sequentially arranged from the upstream side to the downstream side. One weight is provided, and a large number of weights configured in this way are arranged in parallel.

2 and 3, the fluff suppressing device 1 includes a touch roller 12 provided on a drive shaft 10 via a clutch 11 and a drive pulley 13 and a driven pulley 14 that obliquely contact the touch roller 12. A mechanism mainly composed of an endless belt 15 mounted between the endless belts 15 and the touch roller 12 feeds the spun yarn Y while nipping the spun yarn Y to give a false twisting and rubbing action to the spun yarn Y. I have it.

As shown in FIG. 3, the touch rollers 12 are provided over the respective weights of the spinning machine 2 and are driven all at once by a power source (not shown) at the machine frame end of the spinning machine 2. The drive shaft 10 is externally fitted to a cylindrical roller core body 17 that is rotatably provided via a bearing 16.

A flange portion is formed at one end of the roller core body 17 and connected to the clutch 11, and a friction roller 19 for transmitting drive to the endless belt 15 side is fixed at the other end.

The clutch 11 includes a coil 20 fixed to the machine frame via a cover 24, a clutch plate 21 fixed to the drive shaft 10 and rotating together with the drive shaft 10, and a flange of the roller core body 17 via a spring 23. When the coil 20 is in a non-excited state, the movable iron piece 22 is connected to the clutch plate 21 as shown in FIG. However, when the coil 20 is excited by a power source (not shown), the movable iron piece 22 resists the biasing force of the spring 23 due to the attractive force acting between the coil 20 and the movable iron piece 22. The drive shaft 10 is pressed against 21 and is connected to the roller core body 17 via the clutch plate 21, the movable iron piece 22, and the spring 23.

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 27 rotatably supported by a supporting member 26 with a screw 32, and the supporting member 26 is fixed to a bracket 35 fixed to a frame 33 with bolts 34. It is fixed with bolts 36.

A bevel gear 28 is formed on the other end of the rotary shaft 27, and the bevel gear 28 is formed on a rotary shaft 30 of a friction roller 31 rotatably supported by the support member 26. Further, the friction roller 31 is in pressure contact with the friction roller 19 provided on the roller core body 17 of the touch roller 12, whereby the rotation of the roller core body 17 is caused by the friction rollers 19, 31 and the rotary shaft. The endless belt 15 is transmitted to the drive pulley 13 via 20, a pair of bevel gears 29 and 28, and the rotating shaft 27, 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 38 provided on a support member 37, and the support member 37 is fixed to the support member 26 by a bolt (not shown). A yarn guide member 39 is provided on the lower surface of the support member 37 to prevent the spun yarn Y from flowing in the driving direction 40 of the endless belt 15 and from escaping by the touch roller 12.

Next, the operation will be described based on the above embodiment.

In the spinning machine 2 shown in FIG. 1, a sliver S supplied from a can 3 is drafted by a drafting device 4, then false twisted by an air spinning device 5 and sent out as spun yarn Y by a delivery roller 6. Many fluffs are formed on the surface of the spun yarn Y in this state by the action of air during spinning. The spun yarn Y sent out from the delivery roller 6 contacts the touch roller 12 and the touch roller 12 in the fluff suppressing device 1, and is driven in the direction of the arrow 40 in FIG. 2 on the contact surface. The yarn is sent while being nipped with the endless belt 15. At this time, the spun yarn Y is given a false twisting and rubbing action, so that the fluff on the surface of the spun yarn Y is caught in the yarn itself and becomes substantially fluff. The spun yarn Y that does not exist is sent out to the downstream side, passes through the yarn clearer 8, and is wound up as a package P in the winding device 9.

When performing maintenance work such as replacement of the endless belt 15 of the fluff suppressing device 1 in any weight of the spinning machine 2 or adjustment of contact pressure of the belt 15 to the touch roller 12, The clutch 11 on the weight is disengaged to cut off the transmission of rotation from the drive shaft 10 to the roller core body 17, thereby stopping the touch roller 12 and the friction roller 19, and the endless belt 15 is also stopped. Even during operation of the machine base of No. 2, it is possible to perform the above-mentioned work in a state where the rotation of the drive shaft 10 is not stopped and only the fluff suppressing device 1 in this weight is completely stopped.

In the above-described embodiment, an example in which an excitation type electromagnetic clutch is used as the clutch 11 is shown, but the present invention is not limited to this, and the same effect can be obtained by using another type of clutch. The power consumption can be reduced by using a non-excitation type electromagnetic clutch.

Further, in the above-described embodiment, an example is shown in which only the fluff suppressing device 1 can be driven / stopped for each weight, but in addition to this, the draft device 4, the delivery roller 6, the winding device 9 are also provided. It may be possible to drive and stop each weight. Further, in the above-described embodiment, an example in which the touch roller 12 and the endless belt 15 are used as the pair of nip members forming the fluff suppressing device 1 is shown, but rollers may be used instead of the endless belt 15. Also, an endless belt may be used instead of the touch roller 12. Further, although the spinning machine 2 provided with the air spinning device 5 is shown as an example of the textile machine in the above-described embodiment, the present invention is not limited to this, and various spinning machines, winders, and other various types of fluff suppression are effective. It can be implemented in textile machines.
