Field of the Invention The present invention relates to a developing device for a photosensitive resin plate used for flexographic printing or the like, and more particularly, to prevent the plate from being displaced or deflected from a conveying path by the movement of a brush. In addition, the present invention relates to a photosensitive resin plate developing apparatus capable of uniformly removing the resin material in the unexposed portion over the entire plate.

It is particularly suitable for flexographic printing.

けることにより、未露光部分を除去する方法。In the production of the above-mentioned photosensitive resin plate, a so-called developing step of removing the resin material in the unexposed portion after exposing the printing pattern is essential, followed by a purifying step,
The drying step and the post-exposure step are sequentially performed. The following methods (a) to (c) are typical methods employed in the developing step. (A) A method in which compressed air is blown onto the photosensitive resin plate and the unexposed portion is blown off to form a convex portion. (B) A method in which a developing solution (hereinafter also referred to as a washout solution) is jetted toward the photosensitive resin plate at a constant pressure, and the unexposed portion is blown off or washed away. (C) A method of removing the unexposed portion by spraying a developing solution or immersing the photosensitive resin plate in the developing solution and rubbing a brush or the like on the plate surface of the photosensitive resin plate.

つ、未露光部分を剥ぎ取るものである。It is expected that the method (c) has the highest effect of removing the unexposed portion, and for example, JP-A-62-217249 is known. This technology uses multiple rotating brushes to move the rotating brush group together in a reciprocating direction in a direction orthogonal to the direction in which the photosensitive resin plate is conveyed. The unexposed portion is stripped off while preventing deviation of the resin plate (changing the orientation of the photosensitive resin plate).

った。。By the way, in the technique of the above publication, since the brushes are rotated in opposite directions, it is possible to prevent the deviation of the photosensitive resin plate when the brushes are rotated in the same direction. Since the rotating brush group is configured to reciprocate together, there is a problem in that a positional deviation (a phenomenon in which the plate itself shifts in a direction intersecting the transport direction of the photosensitive resin plate) occurs. This problem was particularly remarkable in a system in which only the front part of the plate is fixed and the plate is conveyed so as to be dragged. ..

理するときにはこの不具合が顕著にあらわれた。Even when a plurality of rotating brushes are arranged adjacent to each other, a planar gap causes a gap between the circular rotation loci of the rotating brushes. Has a problem that it is not uniformly applied to the printing plate. This problem was particularly noticeable when the photosensitive resin plate was fixed in a fixed position for development processing.

う。On the other hand, in order to completely remove the unexposed portion around the exposed portion of the fixed photosensitive resin plate, the bristles of the brush should be entirely covered with respect to the periphery of the exposed protrusion in plan view. It must act from the circumferential direction to peel off the unexposed portion.If this action is insufficient even partially, the unexposed portion will not be removed in the part around the convex portion. It remains and impairs its function as a printing plate.

It is an object of the present invention to provide a developing device capable of preventing the photosensitive resin plate from being displaced due to the force in the horizontal direction accompanying the movement.

(Indicated by the white arrow) adjacent to each other. Further, as shown in FIG. 2 or 3, each moving brush 13a (13b) has a pair of crank arms 15a, 15a (15b,
15b) are respectively connected to the arms 15a, 15a (15b, 15b).

され、結局版は位置ずれを生じなくなる。The crank arms 15a and 15b of the adjacent moving brushes 13a and 13b are arranged so as to be offset by 180 degrees, and the chain 16 is stretched so that the shafts 14a and 14b rotate in opposite directions. To be done. That is, when the chain 16 is moved in the arrow K direction in FIG. 3, the rotary shaft 14a and the crank arm 15a rotate in the arrow X direction, and the rotary shaft 14b and the crank arm 15b rotate in the Y direction opposite to the X direction. It is found, in the direction crossing the conveying direction S of the photosensitive resin plate 1, the mobile brush 13a along with moves in the arrow X 1 -X 2 direction, moving the brush 13b is moving in the arrow Y 1 -Y 2 direction Then, the moving brushes 13a and 13b adjacent to each other move in the directions opposite to each other so as to rub (side portions). Therefore, the photosensitive resin plate 1, which is conveyed so as to be in contact with the lower side of the moving brush group 13, will not be displaced in a direction intersecting the conveying direction. This is because in the above-mentioned crossing direction, the adjacent moving brushes try to pull the plates in the opposite directions and these forces cancel each other out so that the plates are not displaced.

In the reciprocating movement in this direction, all the moving brushes 13a,
13b ... move in a lump, so adjacent moving brushes 13
There is no possibility that the a and 13b collide with each other to stop the movement or that the moving brushes 13a and 13b are largely separated from each other.

In the plate 1, the resin material in the unexposed portion around the exposed convex portion is reliably removed by the brush bristles.

It can be rubbed uniformly against the surface, and the unexposed area can be removed without damaging it, and uneven development does not occur.

止される。The number of revolutions of the moving brushes 13a and 13b, the eccentric length of the crank arms 15a and 15b, and the reversal period of the rotation direction can be arbitrarily selected according to the type and size of the photosensitive resin plate 1. Preferably, the rotating speed of the moving brush is 30 to 90 rpm, the eccentric length is 20 to 50 mm, and the reversing period is 0.
It is recommended to set within 5 to 3 minutes. On the other hand, the shape of the moving brushes 13a, 13b is not limited to a rectangular shape, but may be a polygonal shape or the like, and the number of arrangements is an odd number of 3 to 9 so that the bridging condition of the chain 16 is satisfied as described above and the movement is reversed. By making the total areas of the moving brushes 13a and 13b equal to each other, the displacement of the plate 1 in the intersecting direction is completely prevented.

It is desirable to set it higher than the b-brush arrangement position of b ..., and this can prevent the surfactant and the like contained in the washout liquid 3 from foaming. Further, it is preferable to form a plurality of through holes 130 in each of the moving brushes 13a and 13b, so that a new washing liquid 12 can be obtained.
Is easily supplied to the plate surface and also acts as an air vent hole to prevent air from remaining between the bristles and causing foaming. Reference numeral 11B in FIG. 4 indicates an adjuster for raising and lowering the bottom surface 11A of the tank, and the adjusters provided at the four corners allow the bottom surface 11A of the tank to be adjusted up and down according to the thickness of the plate.

When a 610 x 460 mm photosensitive resin plate (Cosmolite manufactured by Toyobo Co., Ltd.) was conveyed at a low speed of 1.5 mm / min in the direction of the white arrow S, the photosensitive resin plate 1 meandered. In addition, it was possible to completely remove the resin material in the unexposed portion without remaining, and it was possible to form a beautiful printing plate without redeposition of the resin material on the plate surface.

It has become possible to uniformly remove the resin material in the portion. Further, the cured portion (convex portion) exposed on the plate surface can be rubbed with the brush bristles over the entire circumference thereof, and even in microscopic view, the unexposed portion does not remain around the convex portion.
