Abstract

(57) [Abstract] [Purpose] An object of the present invention is to obtain a cleaning device that can easily remove fly dust adhering to a draft roller or an apron. A flexible member is provided so as to be capable of contacting a draft roller or an apron, and a drive means for intermittently abutting the flexible member on the draft roller or apron is provided.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a cleaning device for a draft device.

[0002]

[Prior art]

 In a draft device, for example, a four-wire draft device including a back roller 1, a third roller 2, a middle roller 3, and a front roller 4 shown in FIG. For cleaning, as shown in FIGS. 4 and 5, a rubber band 7 is pressed against the outer peripheral surface thereof, and the contact pressure of the rubber band 7 scrapes off the cotton wool adhering to the surface of the bottom apron 6 and the cotton wool scraped off. Is suctioned off by the suction duct 8.

However, since the cotton dust cannot be reliably and sufficiently sucked and removed by the suction duct 8, the cotton dust is accumulated between the bottom apron 6 and the rubber band 7 to form a lump, and the pressure contact force of the rubber band 7 is finally exerted. Against the rubber band 7, the rubber is mixed with the sliver S being fed from the back roller 1 to the middle roller 2 to generate a slab, or the air spinning nozzle 9 adjacent to the downstream side of the draft device is clogged. Was causing a problem.

[0004]

[Problems to be solved by the device]

 The invention is to obtain a cleaning device for a draft device, which can reliably remove fly dust adhering to a draft roller or an apron before it becomes lumpy, and prevent slab formation and clogging of an air spinning nozzle. With the goal.

[0005]

[Means for Solving the Problems]

 The flexible member is provided so as to be capable of contacting the draft roller or the apron, and the flexible member is provided with a drive means intermittently abutted against the draft roller or the apron.

[0006]

[Action]

 The cotton wool attached to the draft roller or apron is blown off, and the blown cotton wool is sucked and removed into the dust collector. As a result, it is possible to prevent the cotton wool from wrapping up or becoming clumped on the draft roller or apron, and as a result, it is possible to prevent the generation of slabs and the like, and the clogging of the air spinning nozzle.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a view showing a drafting device equipped with a cleaning device of the present invention, showing a four-way drafting device including a back roller 1, a third roller 2, a middle roller 3 and a front roller 4. There is. Reference numeral 6 denotes a bottom apron mounted on the bottom roller 5 of the middle roller 3, and the bottom apron 6 rotates with the driving of the bottom roller 5 rotating counterclockwise. This structure is the same as the conventional draft device shown in FIG. 3, and therefore the same parts are designated by the same reference numerals.

Reference numeral 10 denotes a cleaning device of the present invention, which is rotatably supported by bearings 13 and 14 on a front surface of a frame 12 having an apron belt guide 11 on an upper portion thereof as shown in FIGS. 2 and 3. The shaft 15 is provided with a dust collector 17 having a suction pipe 16 at the bottom thereof.

An L-shaped member 20 having a parallel portion 18 and a rising portion 19 is fixed to the shaft 15, and both ends of the bearing portion 4 and the parallel portion 18 are locked to the portion. A spring 21 fitted in the shaft 15 is provided.

Further, a flexible member, for example, both leg ends of a belt 22 folded in two are brought into contact with both the front and back surfaces of the parallel portion 18 of the L-shaped member 20, and the backing pads 23 and 24 are attached from both the front and back surfaces. The belt 22 is fixed by contacting and screwing.

The tip of the rising portion 19 of the L-shaped member 20 is constantly in contact with the peripheral surface of the shaft 25 of the bottom roller 5, and a cam 26 for swinging the L-shaped member 20 about the shaft 15 is provided on the shaft 25. Has been. The cam 26 is constituted by fixing a ring 27 to the shaft 25 of the bottom roller 5 that positively rotates, and the mounting convex portion 28 of the ring 27 is arranged so as to contact the rising portion 19 of the L-shaped member 20. Therefore, the convex portion 28 presses the rising portion 19 of the L-shaped member 20 every one rotation of the shaft 25, so that the belt 22 swings in the clockwise direction against the shaft 15 and the urging force of the spring 24. Move. When the shaft 25 further rotates and the contact is released, the belt 22 oscillates counterclockwise around the shaft 15 by the urging force of the spring 24, and the above operation is repeated for each rotation of the shaft 25. 29 is a stopper as a detachment preventing member.

Since the cleaning device of the present invention has the above-described structure, the fly dust adhered to the surface of the bottom apron 6 is scraped off at the curved portion of the belt 22 which intermittently contacts the bottom apron 6 due to the rocking. Then, it is sucked and removed into the dust collector 17. As a result, it is possible to prevent the cotton wool from wrapping up or clumping on the bottom apron 6, and as a result, it is possible to prevent the generation of slabs and the clogging of the air spinning nozzle.

As the belt 22 used, rubber having an appropriate elasticity or other appropriate flexible member is used.

In the above-mentioned embodiment, the fly cotton attached to the bottom apron 6 of the four-wire draft device has been described, but the present invention is not limited to this, and the fly cotton attached to another draft roller is removed. It can be used as a cleaning device, and further, the device of the present invention can be provided in a three-wire draft device or a five-wire draft device to clean the draft roller or apron.

Although the belt 22 has been illustrated and described as being oscillated once for each rotation of the cam 26, the number of times the belt 22 is oscillated is increased by providing a plurality of convex portions 28 on the ring 27. Of course, it is possible to increase the frequency of scraping off the cotton wool.

[Effect of device]

 As described in detail above, in the cleaning device of the present invention, the flexible member is provided so as to be able to contact the draft roller or the apron, and the flexible member is provided with the driving means intermittently abutted against the draft roller or the apron. Since it is provided, the fly dust adhering to the draft roller or apron is actively scraped off by a flexible member that intermittently contacts the draft roller or apron by swinging, and is sucked and removed into the dust collector. can do. This prevents the cotton wool from wrapping up or becoming clumped on the draft roller or apron. As a result, the generation of slabs is prevented, and the cotton wool scraped off is re-worn as before. It has become possible to spun out high-quality yarn by completely preventing the trawl that mixes with the sliver to generate slabs or causes clogging of the air spinning nozzle.
