  The apparatus for drying a liquid plate photosensitive resin relief plate according to the present invention has a small contact area between the liquid plate photosensitive resin relief plate and the convex portion even if the liquid plate photosensitive resin relief plate is wet with water by post-exposure treatment. The friction resistance when the liquid plate photosensitive resin relief plate is carried in is small, and the liquid plate photosensitive resin relief plate can be smoothly carried into the casing. Therefore, there are few troubles such as bending of the liquid plate photosensitive resin relief plate during carrying in, and the quality of the liquid plate photosensitive resin relief plate can be improved.

  An embodiment of a drying apparatus for a liquid plate photosensitive resin relief plate according to the present invention will be described with reference to the drawings.

  The drying apparatus 1 of the present embodiment is a box-shaped casing having a plane area and a height sufficient to carry the liquid plate photosensitive resin relief plate 2 in a substantially horizontal state and to store drying means (not shown). 3 (see FIGS. 1 and 2). Although the illustration of the rear surface of the casing 3 is omitted, the casing 3 is connected to the upper edge of the casing 3 so as to be rotatable by a hinge mechanism, and the rear surface is opened manually or electrically to be an opening of the casing 3. The

  An inclined guide 4 is connected to the bottom surface of the casing 3 so as to be continuous with the edge on the back side (see FIG. 2). The inclined guide 4 is substantially equal to the width dimension of the casing 3 so that the liquid plate photosensitive resin relief plate 2 can be slid along the inclined guide 4 and smoothly moved to a substantially horizontal state in the casing 3. Three plate members are connected in an arc shape.

  Stored in the casing 3 is drying means for drying the water adhering from the liquid plate photosensitive resin relief plate 2 by post-exposure processing by dehumidification and generation of hot air (not shown).

  A carry-out door for taking out the liquid plate photosensitive resin relief plate 2 after drying is connected to the side surface of the casing 3 by a hinge mechanism so as to be opened and closed (not shown).

  That is, the drying apparatus 1 having the above-described configuration is carried into the casing 3 while being suspended from above along the inclined guide 4 and is in a substantially horizontal state while sliding the bottom surface of the casing 3 in the same manner as a typical drying apparatus. The liquid plate photosensitive resin relief plate 2 is dried by a drying means provided in the casing 3. In particular, a plurality of convex portions 5 that reduce friction with the liquid plate photosensitive resin relief plate 2 are formed on the upper surface of the inclined guide 4 substantially in parallel with the loading direction of the liquid plate photosensitive resin relief plate 2. Features (see FIG. 3). Even if the liquid plate photosensitive resin relief plate 2 is wet with water by post-exposure treatment, the liquid plate photosensitive resin relief plate 2 is carried in because the contact area between the liquid plate photosensitive resin relief plate 2 and the projections 5 is small. In this case, the liquid plate photosensitive resin relief plate 2 can be smoothly carried into the casing 3. Therefore, there are few troubles such as the liquid plate photosensitive resin relief plate 2 being bent during the carry-in, and the quality of the liquid plate photosensitive resin relief plate 2 can be improved.

  The convex portion 5 has a length that can be accommodated in each plate material of the inclined guide 4, and is made of a resin that is molded to a height (for example, about 50 mm) where the placed liquid plate photosensitive resin convex plate 2 does not contact the inclined guide 4. It is a rod-shaped member. In this embodiment, a rod-like member 6a joined to the upper plate of the tilt guide 4 and a rod-like member 6b joined to the middle and lower plate members are prepared.

  The rod-like member 6a is joined to the upper plate by bonding means such as an adhesive with an interval (for example, about 100 mm) set so that the placed liquid plate photosensitive resin relief plate 2 does not contact the plate. Has been. The upper end corner of the rod-like member 6a is chamfered so that the liquid plate photosensitive resin relief plate 2 to be carried is not caught (see FIG. 3).

  The rod-like member 6b has a lower end joined to, for example, a wooden base 7 by a joining means such as an adhesive (see FIG. 4). Incidentally, in the rod-shaped member 6b of the present embodiment, the liquid plate photosensitive resin relief plate 2 placed with a length equal to that of the rod-shaped member 6b in the longitudinal direction of the rod-shaped member 6b is further The convex portion 8 having a height (for example, about 15 mm to 20 mm) that does not contact the upper surface is integrally formed, and the contact area with the liquid plate photosensitive resin relief plate 2 is further reduced to reduce the frictional resistance. (Invention of Claim 3).

  The bar-shaped member 6b is spaced from the middle and lower plate members of the inclined guide 4 with a space (for example, about 100 mm) set so that the liquid plate photosensitive resin relief plate 2 placed thereon does not contact the plate member. It is joined by joining means such as bolts via the pedestal 7 (see FIG. 3, invention of claim 2).

  The drying apparatus 1 of the present embodiment can be carried in while sliding the liquid plate photosensitive resin relief plate 2 into the casing 3 on the upper surface of the inclined guide 4 (in the illustrated example, the middle and lower plate members) and the bottom surface of the casing 3. In addition, a guide roller 9 is provided substantially in parallel with the carrying-in direction of the liquid plate photosensitive resin relief plate 2 (see FIGS. 1 and 3 and claim 4).

  The guide roller 9 is configured such that a plurality of rollers 10 are rotatably supported by a frame material 11. That is, both sides of the rotating shaft of the roller 10 are joined to the vertical piece of the L-shaped frame material 11 so that the outer peripheral upper end of the roller 10 is disposed at a height position substantially equal to the upper surface of the convex portion 8 of the rod-shaped member 6b. The horizontal piece of the frame member 11 is joined to the upper surface of the inclined guide 4 or the bottom surface of the casing 3 by a joining means such as a bolt (the invention according to claim 5).

  The roller 10 is preferably supported eccentrically (invention 6). The liquid plate photosensitive resin relief plate 2 is brought into close contact with the roller 10 due to vibration generated when the roller 10 rotates, and the rotational force of the roller 10 is easily transmitted to the liquid plate photosensitive resin relief plate 2, so that the liquid plate is surely provided. The photosensitive resin relief 2 can be carried into the casing 3. At this time, the roller 10 is disposed at a height position where the outer peripheral upper end on the short diameter side is substantially equal to the upper surface of the convex portion 8 of the rod-shaped member 6b.
