Abstract

Invention m. B. used for the manufacture of offset printing plates on pre-sensitized mono and polymetallic plates and ensures a stable quality of processing. The processing solution, poured into the container 5, is pumped by the pump 7 through the discharge pipeline 8 into the chamber I to the shower elements 3. After interacting with the material 15, the solution is discharged through the pipeline 4 to the second tank 6. Information about the total consumption of the processing solution from the tank 5 and filling the container 6, the sensors 13 installed therein transmit to the control unit 12, a switching valve 9 and a means for alternately collecting the solution, which can be made in the form of the valve 10. 2 3.

This invention relates to devices for

; processing of photosensitive materials and can be used in the printing industry, in particular, for the manufacture of offset printing plates on previously susceptible mono- and polymetallic plates.

I The purpose of the invention is to ensure a stable quality of processing.

 FIG. 1 shows a block diagram of the device; in fig. 2 and 3 are embodiments of the device.

The device comprises a treatment chamber 1, a transporting mechanism 2, a perforating elements 3, a drain pipe 4, as well as a circulation system for the treatment solution, including storage tanks 5 and 6, a pump 7, pipelines 8, a valve 9 for alternately directing the solution to be drained in the tank and the means of alternate sampling solution from the tanks.

The tool alternate sampling solution can be made in the form of a valve 10 (Fig. 1, 3) or in the form of an additional pump 11 (Fig. 2). The pickup means and valve 9 are controlled by block m 12, which receives information about the solution level in containers 5 and 6 from sensors 13. The camera also contains a support table 14 for the material being processed 15. Switching pump 7 (or 11) on and off is carried out by a limit switch 16, with which the material to be processed 15 interacts through a spring-loaded lever 17. The additional pump 1 1 is connected via a pipe 18 to the additional components 19.

The device works as follows. In one of the containers, for example, capacity 5, the treatment solution is poured. The processed material 15 is fed into the chamber 1 while it is through the lever 17 interacts with the limit switch 16, which turns on the pump 7. The processing solution through the discharge pipe 8 enters the mutation elements 3. The processed material 15 is captured by the transporting mechanism 2 and is passed through the chamber 1 on the table 14. The treatment solution interacts with the material 15 and through the pipe 4 and the valve 9 is discharged into the container 6. When the treatment of the processed material 15 is stopped on the lever 17 and the final switch The holder 16 shuts down the pump 7.

When applying the following batches of processed material, the cycles are repeated. The full flow of the solution from the tank 5 and the filling of the tank 6 are signaled by sensors in the control unit 12. After filling the tank 6, a command is entered into the control unit to switch the valves 9 and 10 and to prepare the power supply circuit of the pump 11 (Fig. 2). When processing the next batch of material 15, the supply of the processing solution to the bleeding elements 3 (19) is carried out from the tank 6, and the spent solution is collected in the container 5. In the future, the cycle is repeated.

To ensure a stable quality of material processing after transferring the solution from one container to another, corrective additives are introduced into it or the processing time given by the control unit is changed.
