Description

The invention relates to the printing industry, in particular to devices for processing photographic materials in a printing house and a photographic laboratory.

The aim of the invention is to improve the reliability of work, quality of processing and simplify the design.

Figure 1 shows the device, a general view; figure 2 - the device with the location of the overflow pipe inside the tank, a General view; on fig.Z - section aa in figure 1.

The device contains a container 1 for treatment solutions, a carrier of 2 photographic materials 3, clamps 4, a partition 5 with a relief valve 6. an overflow pipe 7 with a check valve 8 and a filter 9, a drain valve 10, clamps 11. The drive of the carrier consists of an electric motor 12, gearbox 13, chain transmission 14, eccentric 15 and base 16 connected via studs 17 to partition 5. Electric heater 18, cooling coil 19, thermostat 20 and electromagnetic valve 21 are included in the thermostating system.

In the embodiment with the location of the overflow pipe in the tank for processing solutions (Fig. 2), the carrier drive is located under the bottom of the tank and is designed as an eccentric 22. The gearbox with an electric motor located on the output shaft, has a spring-loaded pusher 23 rigidly connected through pipe 24 with a baffle 5. A pusher 23 with a sliding bearing 25 is located in a pipe 26, which is fixed in the bottom of the container. In the pipe 24 there are openings along its entire length above the partition 5, as well as a check valve 27. The partition 5 rigidly attached to the pipe divides the container into two parts, one of which is in the temperature-controlled tank and the other in the main cavity of the tank.

The device works as follows.

The photo material 3 is fastened with the help of clips 4 on the working surface of the carrier 2, made in the form of a removable drum. Then the carrier with the photo material is installed in the container 1 filled with the processing solution and attached to it or to the pipe 24 with the help of fixethedrons

11. When you turn on the drive partition 5 begins to make a reciprocating motion. When lifting its solution from the upper cavity of the tank 1 enters the

bottom through valve 6. When lowering the partition 5, valve 6 closes, valve 8 opens and solution nq overflow pipe 7 through filter 9 enters the upper cavity of the container. In this way, the solution is circulated in the container of the device. Then the cycle repeats.

In the second embodiment of the circulation system, the solution from the lower cavity of the container flows evenly into the top

cavity through the holes located along the entire length of the pipe 24 above the partition 5.

Claims (4)

1. A device for processing fstomete rials containing a container for the processing solution with a removable photographic material carrier and a means for circulating the solution, characterized in that, in order to increase the reliability of the work, the quality of processing and simplify the design, the solution circulation means horizontal transfer with an overflow valve installed with the possibility of return-accessible movement in a vertical plane in the tank for processing i-s, and overflow pipe an inverse with respect to the septum valve g linking the top and bottom of the-vessel walls is flax cavity, thus, eregorodkz mounted under the carrier of the photographic material. 2. The device according to claim 1, that is, that the overflow pipe is installed outside the tank for solutions or into the tank, the passage through the peretrodyu / t is rigidly connected with it. 3. The device according to claim 2, that is, with the fact that in the wall of the overflow pipe with its location in the tank; above the point of its connection with the partition, and holes are made at different levels 4. The device according to claim 1, that is, with the fact that the carrier of photographic material is fixed on the partition. I  tez l A-A 15 vz. wm Sh. 77/7 /. figs
