Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a processing tank array for developing a photographic photosensitive material, for example, a negative film or color photographic paper.

[Conventional technology]

A photographic light-sensitive material development processing apparatus includes a processing tank row in which a color developing tank, a bleach-fixing tank, and a rinsing tank are arranged in order.
The photographic light-sensitive material is guided into each of these processing waters by a guide device or the like, and development processing is continuously performed. In the above-mentioned processing tank row, usually, 5 to 6 processing tanks are arranged side by side.

However, since the above-mentioned processing tank row is configured by arranging a plurality of processing tanks, when cutting and joining plate materials, it is suitable for small-quantity production, but the number of steps is large and the manufacturing cost is increased. There is a problem.

On the other hand, as shown in, for example, Japanese Utility Model Laid-Open Publication No. 1-103840, a processing tank row in which a cross-section is formed by using a U-shaped or square-shaped or Z-shaped molding material to reduce the number of joining steps has been proposed. ing.

[Problems to be solved by the invention]

However, in the case of a processing tank row using a molding material having a U-shaped or Z-shaped cross-section, each molding material is joined at a corner portion of the processing tank. It becomes difficult because of the corners. For this reason, there is a problem that burrs due to welding or adhesion and fine irregularities on the joining surface remain.

Furthermore, since the joint at the corner cannot be finished to a smooth surface with high accuracy, the processing liquid tends to crawl up due to the capillary phenomenon, and the inside of the processing apparatus may be contaminated with the processing liquid.

Further, in the case of a processing tank using a molding material having a square cross section, although there is no inconvenience due to the above-described joining, when the processing tank row is used, two partition plates of adjacent processing tanks are used. There is a problem that the material is wasted. In addition, a molding material having a square cross section has a problem that it is difficult to form a processing tank having a large opening because extrusion molding and the like are difficult when the opening area is large.

The present invention has been made to solve the above-described problems, and can reduce the number of assembling steps, can easily finish a joint, and can prevent a processing liquid from climbing up. It is an object of the present invention to provide a row of photosensitive material processing tanks.

[Means for solving the problem]

In order to achieve the above object, the present invention provides a frame using an H-shaped member in which flanges are integrally formed on both sides of a plate portion, arranging a plurality of these members, and joining the abutted flanges to form a frame. The bottom plate is joined to the bottom of the box. Also,
Another invention joins a U-shaped member to both ends of the processing tank row of the above invention, and also joins a bottom plate to a frame of this U-shaped material and an H-shaped material,
It constitutes a processing tank row.

[Action]

In the present invention, the flanges of the H-shaped members are butted against each other,
In order to join these flanges, a joining portion is located near the center of the side surface of the completed frame body, so that finishing can be easily performed. Then, the joining portion is smoothed by the finishing process, and the joining portion is not located at the corner portion, so that the treatment liquid is prevented from rising due to the capillary phenomenon.

〔Example〕

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is an exploded view of the processing tank row divided into constituent members. The processing tank row 10 includes extruded members (hereinafter, referred to as U-shaped members) having a U-shaped cross section disposed at both ends.
Extruded members (hereinafter, referred to as H-shaped members) 13 to 15 each having an H-shaped cross section disposed between them, and a frame formed into a rectangular cylindrical shape by joining these U-shaped members and the shaped members 17 (2nd
(See the figure) and a bottom plate 18 that closes the lower end opening.

The U-shaped members 11 and 12 and the H-shaped members 13 to 15 are formed by extruding a synthetic resin such as vinyl chloride or stainless steel, which is not affected by the processing liquid. Each of these profiles 11-15
Is cut to a length corresponding to the depth of each of the processing tanks 10A to 10E.

The U-shaped members 11, 12 are provided with flanges 11B, 12B on both side edges of the plate portions (webs) 11A, 12A, and are configured so that the cross section becomes a U-shape. In addition, H-shaped material 13
15 are provided with flanges 13B to 15B on both side edges of the plate portions 13A to 15A, and are configured so that the cross section becomes H-shaped.

The joining of each of these formations 11 to 15 is performed by the flanges 11A to 15A
The welding is performed by abutting and welding each other, whereby a rectangular cylindrical frame 17 is formed. The joint 20 is finished smoothly after joining. The bonding can be performed by ultrasonic welding or the like, in addition to the bonding or welding using an adhesive or a solvent.

After the smoothing of the joining portion 20, the bottom plate 18 is joined to the frame 17. Because the joint of the bottom plate 18 is located at the bottom of the processing tank. It is not necessary to consider the rise of the processing liquid due to the capillary phenomenon as described above. For this reason, smooth processing like the above-mentioned joint part 20 is unnecessary, and simple finishing which only removes burrs etc. may be sufficient.

Next, a description will be given of a processing tank array having different processing tanks in place of the processing tank array 10 including the processing tanks 10A to 10E having the same depth.

FIG. 3 shows a processing tank array in which the depths of the processing tanks 30A to 30E are different.
FIG. 3 shows a state in which 30 is assembled to a printer processor 29. As is well known, the depth of each of the processing tanks 30A to 30E and the number of the tanks are determined in consideration of each processing time such as a development processing, a fixing processing, and a cleaning processing. Rinse tank 30 connects tank 30A and bleach-fix tank 30B.
The processing tank array 30 is formed by arranging three rinsing tanks 30C to 30E deeper than C to 30D. In this way, when changing the depth of each processing tank, as shown in FIG. 4, the U-shaped members 31, 32 and the H-shaped members 33 to 35 are cut in accordance with the depth of each processing tank. These are welded to form frame bodies 36A, 36B with different depths.
The unnecessary flange portions 38 (hatched portions in the figure) of the H-shaped members 33, 34 of the frame bodies 36A, 36B, which are stepped, are cut and removed from the frame bodies 36A. After that, each frame 36
A bottom plate 39 is welded to the bottom of A ...
