However, with the rotary brush or the suction device, it is not possible to remove dust from the surface of the platen material which moves the coating device or the printing device at high speed.

Therefore, there has been considered a method of contacting the roller having adhesiveness on the circumferential surface to the plate-making material to stick dust to the outer circumferential surface of the roller.

[PROBLEMS TO BE SOLVED BY THE INVENTION]

However, since the initially adhered roller outer circumferential surface is also covered with dust adhering to the outer circumferential surface and loses adhesiveness, periodic cleaning operations are necessary to remove dust adhering to the outer circumferential surface of the roller.

[ Effects of the Invention ]

(1) According to the present invention as set forth in claim 1, the dust removal roller 17 whose adhesiveness is lost due to the dust adhered to the outer circumferential surface contacts the wiper 18 away from the inner conveying surface 15, and the dust on the outer circumferential surface thereof. It can be used for cleaning again by wiping by the wiper 18 and restoring adhesiveness of an outer peripheral surface.

In the present invention described in claim 1, since the two dust removal rollers 17 and 17 are provided on one side of the inner conveying surface 15, two dust removal rollers 17 and 17 are used alternately. By cleaning by using the same, the object can be achieved without stopping the coating device or the printing device during the cleaning operation.

Therefore, the operation rate of the coating device or the printing device is not lowered by the cleaning operation of the dust removal rollers 17 and 17.

(2) In the present invention described in claim 3, since the detection sensor 20 for detecting contamination of the outer circumferential surface of the dust removal roller 17 is installed toward the outer circumferential surface of the dust removal roller 17, the dust removal roller 17 The dust attached to the outer circumference can be completely removed. For this reason, the dust remaining in the attached state without being wiped is transferred from the dust removal roller to the plate material 11, so that the plate material is not contaminated. Therefore, the dust removing apparatus according to the present invention is particularly suitable as a pretreatment apparatus such as a printing apparatus or a painting apparatus for preventing product defects such as printing defects or painting defects of the platen plate 11 caused by dust attached to the outer circumferential surface. Suitable.

(3) In each of the inventions of Claims 1, 2 and 3, the wiper 18 is mounted on the carrier 19 which is parallel to the shaft center of the dust removal roller 17, so that the narrow wiper 18 Can be cleaned over the entire length of the dust removal roller 17. For this reason, the dust control apparatus may be manufactured so that the cleaning liquid may be automatically supplied to the wiper 18 from one nozzle. In addition, one detection sensor 20 may be mounted on the carrier 19 to produce a dust removal device so that the presence or absence of dust can be irradiated over the entire length of the dust removal roller 17.

(4) In the present invention as set forth in claim 2, one of the front and rear of one of the transport surfaces 15, the front and rear of the front and rear bordering the position where the dust removal roller contacts the inner transport surface 15 of the plate material, and these front and rear Since the conveying rollers 12 and 13 are respectively provided above the other conveying surface 15 of, the outer conveying surface 16 is tilted downward by, for example, the conveying roller 13 in front. The outer conveyance surface 14 can be inclined upward by the rear conveying roller 12.

In this way, the conveyance roller 13 and the conveyance roller 12 of the inner conveying surface 15 which the dust removal roller 17 contacts, and the outer conveying surface 16 and the outer conveying surface 14 which are front-and-surface bounding each other are mutually mutually. By bending in the reverse direction, even when the plate material 11 is bent in the width direction of the cross section, the plate material 11 can be flattened without bending at the position contacting the dust removal roller 17.

In detail, the present invention described in claim 2 will be described. For example, when the curved young bark is bent in the longitudinal direction of the wrinkles, the curved portion disappears and the folded two-sided boundary line It becomes a straight line and becomes almost flat near the folded part. As can be understood by this example, even when the plate material 11 is bent in the width direction, when the conveying surface 15 is bent in the thickness direction with respect to the conveying rollers 12 and 13, the conveying roller ( 12) In the portion adjacent to 13, the curvature disappears and becomes a plane.

For example, when the plate-shaped material 11 is the same as a steel plate, even if it is curved in the width direction from the front of the conveyance roller 13, and the center part becomes concave by bending the edge of both left and right sides upward, It becomes flat between the conveyance roller 13 and the conveyance roller 12 which passed through the conveyance roller 13.

Therefore, after passing through the conveying roller 12, it is returned to the curved state where the left and right both edges are bent upward again by the elastic recovery force with the plate material 11.

On the contrary, when the left and right edges are bent downward from the front of the conveyance roller 13 and the center portion rises, the conveyance roller 13 and the conveyance roller 12 which have passed through the conveyance roller 13 become flat. Thus, after passing through the conveying roller 12, the left and right edges are bent downward again by the elastic recovery force of the plate member 11, and the center portion is returned to the curved state with the center portion rising.

Thus, when the plate-shaped material 11 is strong like a steel plate, it is easy to return to the original curved state at the same time as the conveyance rollers 13 and 12 pass, so that the conveyance rollers 12 and 13 of The gap makes the distance as narrow as possible within the limit in which the dust removal units 21 and 22 can be installed therebetween.

Therefore, since the conveying surface is bent by the two conveying rollers 12 and 13, even if the plate-shaped material 11 is bent in the width direction, the plate-shaped material between the conveying roller 12 and the conveying roller 13 ( The front and back surfaces of 11) become flat planes.

Therefore, since the dust removal roller 17 is provided toward the inner conveying surface 15 between this conveyance roller 12 and the conveyance roller 13, even if the plate-shaped material 11 is curved in the width direction, it contacts with it. There is no gap between the dust removal roller 17.

For this reason, according to this invention of Claim 2, even if the plate-shaped material 11 is curved in the width direction, the dust adhering to the outer peripheral surface is reliably absorbed and removed by the dust removal roller 17, and such dust Since the removal roller 17 is in contact with the flat plate material 11, only the left and right both edges or the center portion are not evenly worn.

The present invention as set forth in claim 4 is provided with the essential components of the dust removing apparatus as set forth in claims 1, 2 and 3, so that the cleaning operation of the dust removal roller having the outer circumferential surface is adhesive is automated, and the plate material is in the width direction. In the case where the rollers are bent, the dust removal rollers can be pressed together without gaps in the width direction of the plate-making material without unnecessarily pressing, and the dust adhered to the surface can be cleaned and adhered efficiently.

In addition, in the matters described in the claims section of the present specification, the numbers corresponding to the numbers shown in the drawings are appended, but the appendix numbers are for easy understanding of the contents of the present specification. The description in the appended claims is not meant to be limited to the description in the drawings.
