Next, the operation of the embodiment of the present invention will be described.

The work W made of strip-shaped steel is pinched between the upper feed roll 2 and the lower feed roll 3 supported by the left and right roll mounts 1 and 1r via the rotary shafts 4 and 5 to correct the curling. It is fed in the direction of the arrow a toward the decorator roll. When the work W is being fed by the two feed rolls 2 and 3 in this way, the rod 22 of the air cylinder 20 is extended and the substrate 16 of the cleaning member 14 is swung around the hinge 15. The non-woven fabric 18 covering the material 17 is brought into sliding contact with the surface of the upper feed roll 2.

At the same time, the air motor 26 is driven, and its driving force is transmitted to the drive shaft 29 through the sprocket 27, the chain 31, and the sprocket 30, and the sprocket 32 provided on the drive shaft 29 and the sprocket provided on the driven shaft 34. The chain 36 wound between 35 is driven. Then, the slider 13 connected to the chain 36 moves along the upper and lower guide bars 11 and 12, and the cleaning member 14 provided on the slider 13 moves in the axial direction of the rotating upper feed roll 2 and its upper feed. Cleaning is performed by removing dust adhering to the surface of the roll 2. When the slider 13 reaches one moving end indicated by the chain line and the dog 39 provided on the slider 13 actuates the limit switch 41, the rotation direction of the air motor 26 is reversed and the slider 13 moves in the opposite direction to the above. . When the dog 38 of the slider 13 that has reached the other moving end shown by the solid line actuates the limit switch 40, the rotation direction of the air motor 26 is reversed and the slider 13 moves again in the opposite direction. Thus, when the slider 13 reciprocates in the left-right direction, the cleaning member 14 provided on the slider 13 cleans the surface of the upper feed roll 2 over the entire length. Thus the upper feed roll 2
When the cleaning is completed, the rod 22 of the air cylinder 20 is contracted, so that the cleaning member 14 swings upward and is separated from the surface of the upper feed roll 2, and at the same time, the movement of the slider 13 by the air motor 26 is stopped.

Although the embodiments of the present invention have been described in detail above, the present invention is not limited to the above embodiments, and various small designs can be made without departing from the present invention described in the scope of claims for utility model registration. It is possible to make changes.

For example, instead of the non-woven fabric 18 provided on the cleaning member 14 and slidingly contacting the upper feed roll 2, it is possible to use another appropriate flexible material. Further, in the embodiment, only the upper feed roll 2 that comes into contact with the surface side of the work W that needs to be particularly strictly prevented from being scratched by dust is cleaned. However, both upper and lower feed rolls 2 and 3 are cleaned as necessary. It is also possible to apply a cleaning member to each. Further, it is obvious that the roll to which the cleaning device of the present invention is applied is not limited to the feed roll of the decorator.

C. Effect of the Invention As described above, according to the features of the invention, the cleaning member provided on the slider is forcibly rocked to the cleaning position by the drive source and is biased toward the roll side at the same position so that the surface of the roll is supported. Since the rolls are cleaned by bringing them into contact with each other, the work of inserting a cleaning member between the upper and lower rolls is not required each time cleaning is performed, and workability is improved, and the work is fed by the rolls. Even during the cleaning, the cleaning of the rolls can be performed in parallel at the same time, which eliminates the need to stop the line for cleaning the rolls, which can contribute to the improvement of productivity.

Further, since the cleaning member is hinged to the slider so that it can swing between the cleaning position and the non-cleaning position, the movement between the two positions can be smoothly performed with little resistance, and the two positions can be forced. The load of the drive source to move is reduced,
Further, the drive source is also used as the urging means for urging the cleaning member at the cleaning position to the roll side, which simplifies the structure and contributes to cost reduction.

Further, in particular, the cleaning member has a core material having a recess having an arc-shaped cross section following the surface shape of the roll, an inner rubber plate laminated so as to double-cover the surface of the core material, and an outer flexible sheet shape. Since the wiping member is provided, the wiping member can be pressed against the roll surface with a proper contact surface pressure without a gap, and minute dust and dirt on the surface can be effectively wiped and removed by the wiping member. Moreover, since the wiping member itself is flexible and the pressing force from the core material is transmitted to the wiping member via the rubber plate in a buffer manner, the damage to the roll surface due to the dust or the like is also effective. Can be avoided. Furthermore, since the sliding contact surface of the wiping member with the roll is an arc surface that follows the roll surface corresponding to the concave portion of the core material, even if the roll surface is a convex curved surface, the cleaning member always plays in a stable posture. It can be pressed accurately on the roll surface without sticking.
