CONSTITUTION:The anastatic material 12 is carried by a conveyor roller 22 to the development part 24. Then a liquid developer 32 is sucked out of a storage layer 34 by a pump 38 and while the liquid developer is sucked from above a washing brush 36, the exposed surface of the anastatic material 12 in the conveyance is brushed with a brush 36 for the development processing. Then a washing part 26 cleans the exposed surface, which is dried at a drying part 28 and exposed at an exposure part 30. The development part 24 is covered with the chamber 70 to confine odor molecules scattered from the liquid developer 32. A slit hole 76 is formed in the interference part between the side wall 72 of the chamber 70 and the conveyance path for the anastatic material 12. The vaporized deodorizer 82 is sent in the chamber 70 from a deodorizer production device 80 through the duct of a pipe 78 and made to react on the odor molecules, thereby eliminating the odor. When the pressure in the chamber 70 becomes high, it is discharged through the hole 76.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a plate-making apparatus that develops a plate material to form an image and makes a plate.

[Prior art]

When a letterpress material that has been exposed to light is inserted into a plate-making device (treleaf processor) that forms an image on a plate material, such as a letterpress material with a photosensitive resin layer, a development (washing out) process is first performed. Then, it is subjected to water washing (squeezing) treatment, drying treatment, and post-exposure treatment, and then discharged. The developer (washing solution) used during the development process is stored in a storage tank in advance, sucked out by a pump, sent to a washing brush on the conveyance path of the letterpress material, and then blown out. There is. The blown out washing liquid falls back into the storage tank and is reused.

[Problem to be solved by the invention]

However, during the development process, the odor (attributable to the material of the plate material) emitted from the washing solution is strong and unpleasant to the operator, and is also environmentally unfavorable.

To solve this problem, it is possible to forcibly eliminate odors by installing a ventilation hood above the storage tank (above the washing brush due to the device configuration), but it is possible to ensure that all odors are guided to the ventilation hood. Can not do it.

We also try to change the materials used for the printing plates to ones that are as odorless as possible, and even if there is a slight odor, we try to avoid causing discomfort.
Although efforts are being made to combine it with fragrances,
Odors cannot be completely eliminated.

The present invention has been made in consideration of the above-mentioned facts, and an object of the present invention is to obtain a plate-making apparatus that can reliably eliminate the odor generated during development processing, does not cause discomfort to workers, and can prevent environmental conditions from being disturbed. be.

[A means of promise to solve problems]

A plate-making apparatus according to the present invention is a plate-making apparatus that develops a plate material to form an image and makes a plate, and includes a storage tank for storing a developer for developing the plate material, and transports the plate material in a predetermined manner. a developing section that performs development processing while being conveyed along a path; a chamber provided to cover the opening of the storage tank and provided with a plate passage hole so as not to obstruct the conveyance path of the plate; and the chamber. and a deodorizing air supply means communicating with the chamber and sending deodorizing air into the chamber.

1 Effect] According to the present invention, odor molecules diffused from the storage tank during development processing remain within the chamber, and therefore do not exit the apparatus as they are. Further, deodorizing air generated by a deodorizing air supply means is fed into the chamber. Therefore, the odor can be eliminated by reacting with the odor molecules diffused within the chamber.
