出し工程に関するものである。 Photosensitive resin plates used as plate materials for letterpress printing are usually used for printing after going through the following plate-making process. That is, (1) a negative film is closely attached to a photosensitive resin plate and irradiated with ultraviolet light. Then, the portion irradiated with ultraviolet light undergoes photopolymerization, forming a latent image. Portions of this latent image are no longer soluble in common solvents. (2) Next, when this photosensitive resin plate is treated with an appropriate solvent, the resin in the areas that were not irradiated with ultraviolet rays will be dissolved and washed out, but the areas that have been irradiated with ultraviolet rays will not dissolve in the solvent. Leave it as is to form a relief. In the above board making process, the step (1) is called exposure, and the step (2) is called washing out. The present invention relates to the above-mentioned cleaning process of plate manufacturing.

置は、
(1) 感光性樹脂版の取付け、取外しに人手を要
し、作業性が悪い。 In such a washing-out device, when the number of washing plates is increased, the concentration of the photosensitive resin plate dissolved in the solvent in the device increases. Therefore, if the printing plate is left to dry after washing, a thin film of resin dissolved in the solvent will adhere to the relief surface, and if used as is for printing, uneven printing and other problems will occur. Therefore, as shown in FIG. 2, it is necessary to wash the plate surface with fresh solvent 5 after washing out. Such a conventional cleaning device has (1) labor required for attaching and detaching the photosensitive resin plate, resulting in poor workability;
(2) 感光性樹脂版の取付け、取外し時のフタの開

災上も問題である。(2) When opening the lid to install or remove a photosensitive resin plate, the surface of the cleaning solvent inside the device will be exposed each time, so when using an organic solvent-based cleaning solution, be careful not to let the solvent vapor reach the operator. Due to concerns about its effects, it is not desirable in terms of occupational safety and health, and is also a problem in terms of disaster prevention.

本発明者等は、これら欠点を克服すべく鋭意検
討した結果、本発明に到達した。 The present inventors have made extensive studies to overcome these drawbacks, and as a result, have arrived at the present invention.

Built-in means for supplying washing liquid to wash out the photosensitive resin plate,
A rotating brush for cleaning, which has a rotation axis perpendicular to the plane of the photosensitive resin plate placed and fixed on the conveyor belt, and rotates along and comes into contact with the surface of the plate, and the print after cleaning is completed. This is a continuous washing device for photosensitive resin plates, characterized by comprising a washing means for washing the plates.
以下に本発明を図面で説明する。 The invention will be explained below with reference to the drawings.
第３図は、本発明の装置の一例である。 FIG. 3 is an example of the apparatus of the present invention.

選択できることは言うまでもない。 Reference numeral 2 denotes a rotating brush for washing (hereinafter simply referred to as the rotating brush), and a conduit 7 for supplying a washing liquid for washing out the photosensitive resin in the unexposed areas is installed in the center of the brush. Reference numeral 8 denotes a crank arm for imparting rotational motion to the rotating brush 2, which has a rotation axis perpendicular to the plate surface, and rotates the rotating brush 2 along the surface of the plate 1 to bring it into contact. The rotation direction of the rotating brush 2 can be selected as appropriate. The rotation speed of the rotating brush 2 affects the washing speed; generally, the faster the rotation speed, the faster the washing speed will be. However, if the rotation speed is too fast, it will have a negative effect on the plate surface being washed, so the rotation speed should be approximately 30 to 300 times/min. Preferably, the rotational speed is in the range of . In FIG. 3, the rotating brush 2 is
Although the rotary brushes 2 are arranged in rows, it goes without saying that the number of rows of the rotating brushes 2 can be selected as appropriate depending on the required washing time and other operating conditions of the device.

方式では、折返し部でブラシは一旦停止させられ
るので現像むらができ易いとい問題点を有する。 FIG. 7 is a schematic diagram for explaining the action of the rotating brush 2 applied to the present invention on the plate 1 conveyed by the conveyor belt 6. That is, as is clear from FIG. 7, the plate 1 conveyed in the direction of the arrow by the conveyor belt 6 is rotated along the surface of the plate 1 while being in plane contact with the rotating brush 2.
As a result, the A1 area receives a leftward brushing action, and the A2 area receives a rightward brushing action, which is opposite to the A1 area. Therefore, since the rotating brush 2 of the present invention makes surface contact with the plate 1 and makes a rotating movement, it is possible to process thick relief materials such as letterpress plates at high speed, and the same rotating brush can handle the plate 1 while it is in progress.
As a result, the printing plate is subjected to a brushing action in the same direction, and a uniform cleaning action is applied to the plate surface. Therefore, there is no need to reverse the rotating brush.
In the generally considered method of reciprocating a rotating brush, the brush is temporarily stopped at the folded portion, which causes a problem in that uneven development is likely to occur.
洗い出し方法としては、洗い出し液をノズルか
ら高速で版面に噴射する方式もあるが、この方式
では次のような欠点がある。 As a washing method, there is a method in which a washing liquid is sprayed onto the printing plate from a nozzle at high speed, but this method has the following drawbacks.
(1) 洗い出し時間が長くなる。(1) Washing out time becomes longer.
(2) ノズルの管理が難しく、洗い出しのムラが発
生し易い。(2) It is difficult to manage the nozzle, and uneven cleaning is likely to occur.

部から供給することが好ましい。 The rotating brush 2 of the present invention, which is in planar contact with the plate 1 and has a built-in cleaning nozzle 9 for supplying a washing liquid for washing out the unexposed portions of the photosensitive resin plate and rotates along the plate surface, overcomes these drawbacks. can. That is, since the cleaning nozzle 9 is built into the rotating brush 2, the liquid can be supplied only to the area being developed while being smoothed by the brush, and since the brush area is large, a sufficient residence time can be ensured. 〓〓〓〓〓
This allows effective development with a small amount of liquid.
In this case, it is preferable to supply fresh washing liquid from the center of the rotating brush.

い。 The important thing about the shape of the plate holding clamp 21 is that the shape of the clamp 21 is as shown in FIGS. 4 and 5.
The angle θ of the arm portion with respect to the surface of the magnetic sheet 22 is 90 degrees. If θ is less than 90 degrees, the brushing force applied in the horizontal direction of the plate exerts a wedge effect on the clamp 21, and the holding force of the clamp 21 is significantly reduced, making it unusable.
Further, the thickness of the clamp 21 is preferably about 0.2 to 0.5 mm from the viewpoint of preventing it from getting caught on the rotating brush 2.

る。 Furthermore, although the use of the present invention is not limited by the type of cleaning liquid or the resin that is the base material of the photosensitive resin plate 1, it is effective for cleaning nylon resin plates using hydrous ethyl alcohol. be.
さらに、本発明の装置に、洗い出しの終つた版
を乾燥する手段や、後露光を行なう手段を必要に
より付設できることは言うまでもない。 Furthermore, it goes without saying that the apparatus of the present invention may be provided with means for drying the washed plate and means for post-exposure, if necessary.
以上のように、この発明の洗い出し装置による
効果をまとめると次の通りである。 As described above, the effects of the cleaning device of the present invention are summarized as follows.
露光済の感光性樹脂版を装置に供給するのみで
感光性樹脂版の洗い出し作業が連続して自動的に
行なえるから、生産能率が向上し、かつ労働安全
衛生上および防災上安全である。 Since the cleaning operation of the photosensitive resin plates can be carried out continuously and automatically simply by supplying the exposed photosensitive resin plates to the apparatus, production efficiency is improved, and it is safe in terms of occupational safety and health and disaster prevention.
回転ブラシは、版と面接触して旋回運動をする
ので、凸版などのレリーフの厚いものを高速で処
理でき、また同一回転ブラシで版は進行中に２方
向のブラツシング作用を受けることになり、版面
にはむらのない均一な洗浄作用が旋される。した
がつて、回転ブラシを逆転させる必要はない。 Since the rotating brush rotates in surface contact with the plate, it is possible to process thick relief plates such as letterpress plates at high speed, and with the same rotating brush, the plate receives brushing action in two directions while it is in progress. A uniform cleaning action is applied to the plate surface. Therefore, there is no need to reverse the rotating brush.
洗浄用ノズルが回転ブラシに内蔵されているた
め、現像加工しつつある部分のみにブラシでなら
されながら液が供給でき、かつブラシ面積が大き
いので充分に滞留時間をとることができ、少量の
液で効果的な現像ができる。 Since the cleaning nozzle is built into the rotating brush, the solution can be supplied only to the area being developed while being smoothed by the brush, and the brush area is large, allowing sufficient residence time, allowing small amounts of solution to be applied. Effective development is possible.
搬送ベルト上に感光性樹脂版を平板部材を介し
て載置固定する版固定用治具を使用し、版の全裏
面を平板部材を介して搬送ベルトに固定したた
め、版はこすり方向が変つても蛇行せず、ブラツ
シングで版が湾曲したり、折れ曲ることがなく、
さらに版面を強い押圧でニツプしないため画像部
を歪ませることはない。 A plate fixing jig was used to place and fix the photosensitive resin plate on the conveyor belt via a flat plate member, and the entire back side of the plate was fixed to the conveyor belt via the flat plate member, so the rubbing direction of the plate did not change. There is no meandering, and the plate does not curve or bend due to brushing.
Furthermore, since the printing plate is not nipped with strong pressure, the image area will not be distorted.
