2. Description of the Related Art FIG. 3 shows a spinning machine on which the present invention is based. The spinning machine has a top arm 2 supported on a spindle 1. The top arm 2 includes a pair of left and right back top rollers 3, 3 and front top rollers 4, 4, and each of the rollers 3, 4 is opposed to a respective bottom roller 5,
6 is pressed against. The rollers 3 and 5 constitute back rollers, and the rollers 4 and 6 constitute front rollers, respectively. A draft device 9 including a pair of aprons 7 and 8 is disposed between the back roller and the front roller. Then, the roving yarn 10 guided and guided by the trumpet 11 is spun into a yarn 12 through the peripheral surfaces of the rollers 3 and 5 having different speeds, the draft device 9 and the peripheral surfaces of the rollers 4 and 6, respectively. Each spun yarn 12 is collected by winding it around a bobbin mounted on a spindle (not shown). By the way, it is known that the honeydew mixed in the roving yarn 10 adheres to the peripheral surfaces of the top rollers 3 and 4, leading to yarn breakage and deterioration of yarn quality. To resolve this situation,
A bracket is attached to each top arm 2, and a cleaning roller that rotates by receiving the rotation of the top roller between the adjacent top arms 2, 2 or a flat plate coated with a gauze or the like is laid horizontally, and the rollers and flat plates are adjacent to each other. Back top roller 3,3
There has been proposed a method of removing a honeydew by contacting the peripheral surface of a honeydew.

[0003]

[Problems to be Solved by the Invention] There are the following problems in the above-mentioned honeydew removal technique.

<A> When the top arm 2 is raised for the purpose of solving a trouble or the like, a roller or a flat plate for cleaning becomes an obstacle, and it is necessary to detach and attach the roller or the flat plate each time. Also, when cleaning the support shaft of the top roller in which fly waste easily accumulates, the roller and the flat plate need to be similarly attached and detached.
Therefore, it takes a lot of trouble to attach and detach rollers and flat plates, which is troublesome.

<B> Since the top roller is cleaned using the weight of the roller or the flat plate, the cleaning roller or the flat plate is heavy, which is inconvenient for transportation and handling.

<C> Although air is blown to eliminate the accumulation of fly waste on the top roller, a cleaning roller, a flat plate, or a bracket supporting the same shuts off the air, and the fly waste is applied to the spindle of the top roller. Easily accumulate.

<D> As a method for preventing the adhesion of honeydew to the top roller, it is known to lower the relative humidity of the spinning environment. However, although this method can prevent the adhesion of honeydew, on the other hand, it is easy for the spinning machine to accumulate fly waste due to the effect of drying. There are drawbacks such as a decrease in quality.

Embodiment 1 An embodiment of the present invention will be described below with reference to the drawings.

<A> Configuration of Top Roller Cleaning Device FIG. 1 shows a top roller cleaning device 30 mounted on the back top rollers 3 and 3 of the top arm 2, and FIG. 2 shows a perspective view of the top roller cleaning device 30. The top roller cleaning device 30 includes a frame 31, an annular pad 32 provided on the frame 31, and a magnet 37 provided at the center of the frame 31. Hereinafter, each part will be described in detail.

<B> Frame As shown in FIG. 2, the frame 31 is formed by punching a thin and thin plate made of spring steel or the like having an appropriate elasticity to form a pair of left and right blade frames 33, 33. The connecting plate 34 is formed by attaching steps 341 and 341 between the respective ends of the 33. An opening 35 that can be fitted to the saddle 20 is formed between the blade frames 33, 33. Further, one of the connecting plates 34
A magnet 37 is fixed to the portion . Step 341,
341 , that is, the distance between the steps 341 and 341 is
The body 21 of the top arm 20 between the steps 341 and 341
It can accommodate a and is set to a dimension that can be fitted with no looseness between the body 21. The opening 35 is set to a size that can be fitted to the saddle 20 of the top arm 2 as a member to which the back top rollers 3 and 3 are attached without rattling. Step 34 at the boundary between the connecting plate 34 and the wing frame 33
The formation of the pads 1 and 341 allows the pad 32 to abut on the peripheral surfaces of the back top rollers 3 and 3 with an appropriate elasticity. By forming an opening 35 in the frame 31 or providing a step 341 between the connecting plate 34 and the blade frame 33, a single top roller cleaning device 30 can be used to change the type of the top depending on the manufacturer (for example, NSK, Sussen, SKF). It is also possible to correspond to an arm.

<C> Pad The pad 32 is mounted on the wing frame 33 and is a member for directly removing the honeydew by directly contacting the peripheral surface of the back-top rollers 3 and 3. The pad 32 has flexibility and moderate elasticity. For example, natural rubber, synthetic rubber, polyurethane elastomer, felt, vinyl chloride resin, cloth tubes,
A known member having a large number of short hairs implanted on the outer peripheral surface of the rubber tube may be used. Alternatively, an unevenness process, an opening process, a creasing process parallel or oblique to the support shaft of the back top roller 3, or the like may be performed so that the surface of the pad 32 has a rough surface. Further, the shape and the material of the pad 32 are not limited to the above, and a known material may be used, or the pad 32 may be attached to only the lower half of each wing frame 33 as long as the above object can be achieved. When the annular pad 32 is used, a diameter that can restrict free rotation of the pad 32 when the pad 32 is mounted on the wing frame 33 is selected. As means for adjusting the elastic contact force with the back top rollers 3, 3, pads 3 having different thicknesses are used.
2 or a method of replacing the wing frame 33 with a frame 31 manufactured by changing the step amount. If the set elastic contact force of the pad 32 that makes elastic contact with the back top rollers 3, 3 is too large, the brake is applied to the back top rollers 3, 3 and there is a concern that spinning may be adversely affected. It is desirable to set in the range of 1200 g.
