Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application in Business A] The present invention relates to a photosensitive material processing apparatus, and more particularly, to a photosensitive material processing apparatus that prevents scattering of a supply liquid and generation of bubbles.

[Prior Art] Some photosensitive material processing apparatuses carry out development processing while conveying a photosensitive material in a processing solution, for example.

In this way, when automatically developing photosensitive materials,
The processing liquid is replenished, and for example, as shown in FIG. 7, the rinsing tank 100 is sometimes replenished with rinsing water from a water supply pipe 101 connected to a water pipe.

This one washes the water supply pipe 101 connected to the water supply 4'J with water.
1 o o to the injection part 10 of the water supply pipe 101.
ta is supplied at a predetermined distance Lllljl from the surface of the flushing water, and overflows from the inner wall 102! A: The buried liquid is drained.

By the way, in this case, for example, if a hole opens in the part totb of the water supply pipe 101 that is immersed in the flushing water,
There is a risk that the dirty washing water in the washing tank will flow back into the water supply pipe 101, which is unfavorable from a safety standpoint.

Also, the distance between the injection part 101a of the water supply pipe 101 and the wall surface 100a of the washing tank 100 is 1! IffL2 and the injection part 101a
If there is no distance 11111LI between and the liquid level of the flushing water,
If the drainage becomes clogged due to the surface tension of the liquid surface or for some other reason and the liquid level rises, there is a possibility that the processing liquid will flow back from the water supply pipe 101.

[Problem to be solved by the invention] Therefore, as shown in FIG.
01 passes through the outside of the washing tank 100, and its injection part 101a
A chisel is placed in the washing tank to supply washing water.

Furthermore, in order to improve safety, the distance jlffL2 between the injection part 101a of the water pipe 101 and the wall surface 100a of the flush a to o, and the distance 111LI between the injection part 101a and the liquid level of the flush water are set large. This prevents backflow to the water supply.

However, if you do this, the injection part of the water pipe and the flush 4f
Since the distance between t and the liquid surface is long, the injection is discharged from a high place, the flow velocity is high, and the flow diameter is large, making it easy for air to get mixed in, foaming, and scattering. For this reason,
Rinse water may mix into other processing tanks, or air bubbles may cause problems such as poor fixing and other changes in processing performance. This results in problems such as a decrease in the safety and processability of the photosensitive material processing apparatus, and conspicuous stains due to scattering of the processing liquid.

The present invention was made in view of the above circumstances, and an object of the present invention is to provide a photosensitive material processing apparatus that prevents the scattering of supplied water and the generation of bubbles.

[Means for Solving the Problems] In order to solve the above-mentioned problems, the present invention provides a photosensitive material processing apparatus that is provided with a water supply pipe to the processing tank so as to supply the processing liquid from the surface of the processing liquid. , is characterized by comprising an auxiliary water supply means for reducing the flow rate of the supply water and subdividing the flow diameter.

In the photosensitive material processing apparatus of the present invention, the auxiliary water supply means may include a pipe member and a dividing member provided inside the pipe member to subdivide the flow diameter of the supplied water.

[Function] In this invention, the supply water is processed 4ff from the injection part of the water supply pipe.
At this time, the feed water hits the auxiliary water supply means, the flow rate is reduced, and the flow diameter is subdivided. Therefore, the level of the processing liquid is less likely to be hit by the supply water.
This prevents the processing liquid from scattering and getting mixed into other processing tanks, and from changing processing performance such as poor fixing due to air bubbles.

Further, in the photosensitive material processing apparatus of the present invention, the auxiliary water supply means includes a pipe member and a water supply means provided inside the pipe member.
% if it is composed of divided members that subdivide the M diameter? The J-shaped structure allows the flow rate of the supplied water to be reduced, and the flow diameter to be subdivided, and scattering at this time can be reliably prevented by the pipe member.

[Example] Hereinafter, an example of the photosensitive material processing apparatus of the present invention will be described in detail based on the accompanying drawings.

Figure 1 below is a schematic diagram of a photosensitive material processing apparatus.

In the figure, reference numeral 1 denotes the main body of a photosensitive material processing apparatus that blocks external light.This equipment is equipped with a supply stage 2 on one side of the main body 1. For example, a roll or sheet-like material that has been exposed to 0 images is A photosensitive material 3 such as a film is supplied from this supply stage 2 into the apparatus main body l. A collection rack 4 is provided on the other side of the apparatus main body 1, and a photosensitive material intake port 5 is provided on the supply table z side of the apparatus main body 1, from which the developed photosensitive material 3 is stored. On the other hand, a photosensitive material outlet 6 is provided on the collecting rack 4 side. Between the photosensitive material inlet 5 and the photosensitive material outlet 6, that is, inside the apparatus main body 1, a large number of conveyor rollers driven at a constant speed by a driving means (not shown) are disposed.
This forms a meandering conveyance path.

A developing tank 8 and a fixing tank 9 are arranged next to each other along this conveyance path.
, a rinsing tank 10, and a drying section 11 are provided, and predetermined amounts of processing liquid are stored in these processing tanks, and each is maintained at a predetermined temperature. In addition, when processing color photosensitive materials, the number of processing tanks for bleaching and fixing increases.

This flushing tank IO is equipped with a water supply pipe 12 communicating with the water supply, and flush water is supplied from an injection part 12a of this water supply pipe 12.

This water supply pipe 12 is attached to the washing tank 10 as shown in FIG. A water supply pipe 12 connected to the water supply passes through the outside of the washing tank 10, and only its injection portion 12 is positioned inside the washing tank to supply washing water.

Furthermore, in order to improve safety, the distance 1111L between the injection part 12a of the water supply pipe 12 and the wall surface 10a of the water wash 4910 is
4, the distance between the injection part +2a and the liquid level of the flushing water is 1! By setting lL5 large, adverse conditions to the water supply are prevented.

The injection part 12a of the water supply pipe 12 is equipped with an auxiliary water supply means 13 that reduces the flow velocity and subdivides the flow diameter.
The impact of the flushing water injected by the auxiliary water supply means 13 directly hitting the liquid surface is reduced, the scattering of the liquid and the inclusion of air bubbles in the liquid are reduced, and the generation of bubbles is prevented.

This auxiliary water supply means 13 consists of a pipe member 14 and a dividing member 15 provided inside this pipe member 14. The pipe member 14 has a predetermined diameter larger than the water supply pipe 12 and is made of, for example, rubber, resin, metal, etc.
It is attached to the side wall 10a of the washing tank 10 via an attachment part 14a formed on the outside.

As shown in FIG. 3, the dividing member 15 is made of axially long blades 15a made of rubber, resin, and metal, for example, and crossed in a cross shape, and has an inclined surface 15b at one end of the blades 15a. It is formed. Although the blades 15a of this dividing member 15 are composed of four blades, the blades 15a are not limited to this,
It is sufficient if it can be subdivided by making it into a plurality of parts and being brought into contact with the washing water.

Therefore, when flush water is supplied from the water supply pipe 12, the flush water projected from the injection part 12a is transferred to the auxiliary water supply means 13.
Abuts against the center of the dividing member 15 at the center to be subdivided into multiple directions, and the impact in the liquid outflow direction hitting the liquid surface of the washing tank 10 is alleviated. In addition, the liquid splashing in the direction perpendicular to the liquid outflow direction hits the pipe member 14 and falls along the wall surface, and is no longer scattered and is gradually supplied to the liquid surface, causing bubbles to be generated on the liquid surface. is prevented.

4 and 5 show another embodiment of the auxiliary water supply means 13. In this embodiment, the pipe member 14 is formed in the same manner as in the previous embodiment, but the one-piece member 16 is constructed as shown in FIG. It is formed with a net 16a. The mesh 16 of this dividing member 16
The mesh a is preferably made of aluminum, for example, and the smaller the mesh is, the better the impact relaxation of the supplied water and the ability to subdivide the flow diameter, but if it is too small, clogging will occur, so it is preferably about 50 to 100 mesh.

Further, the attachment position of the dividing member 16 to the pipe member 14 is not particularly limited, but a position close to the liquid level of the flushing water is preferable since it can alleviate the impact.

Next, in Fig. N6, an example in which the dividing member 15 shown in Figs. 2 and 3 is a blade 15a, and an example in which the dividing member 16 shown in Figs. 4 and 5 is a rope 16a are used. The experimental results for the case where the auxiliary water supply means 1 is connected to the conventional water supply pipe 12 are
This will be explained in comparison with the case where 3 is not used.

In this example experiment, ○ indicates no scattering, △ indicates that there is a risk of occasional scattering to other processing tanks or the outside, and × indicates a judgment level that indicates flow into the equipment that constantly scatters to other processing tanks or the outside. It shows.

When the guide member of this invention was used, very good results were obtained with almost no scattering when the flow rate was low, and even when the flow rate increased, the judgment level did not decrease. .

[Effects of the Invention] As described above, the photosensitive material processing apparatus of the present invention includes an auxiliary water supply means for reducing the flow rate of the supply water and subdividing the flow diameter at the injection part of the water supply pipe that injects the supply water into the processing tank. This reduces the possibility of the surface of the processing liquid being hit by the supply water.
This reduces the chance of the processing solution getting mixed into other processing tanks or changes in processing performance such as poor fixing caused by air bubbles, improving the safety and processing performance of the photosensitive material processing equipment, and also reducing dirt caused by scattering of the processing solution. is reduced.

Further, in the photosensitive material processing apparatus of the present invention, if the auxiliary water supply means is composed of a pipe member and a dividing member provided inside the pipe member for subdividing the flow diameter, the flow rate of the supplied water can be reduced with a simple structure. Moreover, the flow diameter can be subdivided, and scattering can be reliably prevented by the pipe member.

In addition, in the above-mentioned example, washing with water is carried out for 4f! Although the description has been made for the case where water is supplied to the water treatment tank 10, if the water supply pipe is connected to the water supply and water is supplied, the present invention is not limited to the rinsing tank but can be similarly applied to the case where water is supplied to other processing tanks.
