Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic processor for photographic processing (hereinafter sometimes abbreviated as an automatic processor),
More specifically, a waste liquid generated along with the development processing of the photographic light-sensitive material (hereinafter, abbreviated as photographic processing waste liquid or waste liquid).
The present invention relates to an automatic processor capable of reducing the amount of water and effectively utilizing the distillate generated in the evaporative concentration process of photographic waste liquid as the dissolving water for the processing agent and / or the evaporative correction water.

[0002]

BACKGROUND OF THE INVENTION Generally, photographic processing of a silver halide photographic light-sensitive material is carried out by processing steps such as development, fixing and washing with a black-and-white light-sensitive material, and color development and bleach-fixing (or bleaching) with a color light-sensitive material. , Fixing), washing with water, stabilization and the like. In a photographic process for processing a large amount of a light-sensitive material, the components consumed by the process are usually replenished, and the components eluted from the light-sensitive material into the processing liquid are removed to keep the processing liquid component constant. Therefore, a means for maintaining the performance of the processing liquid constant is taken. Specifically, the replenisher is replenished with the treatment liquid for the above replenishment, and a part of the treatment liquid is discarded as a waste liquid out of the system to remove the eluted components.

However, such a photographic processing waste liquid has an extremely high pollution load, and along with the recent tightening of environmental pollution regulations, it is practically impossible to dispose of it in sewers and rivers. For this reason, it is currently in the form of recovery processing, and a specialized contractor is in charge of this. However, the method of entrusting a waste liquid treatment company with waste liquid treatment has the drawbacks that a considerable space is required to store the waste liquid and the recovery cost is high. Further, in order to detoxify the collected waste liquid, an extremely large-scale facility is required, and installation of such a treatment facility requires enormous cost and the treatment cost becomes expensive. For this reason, some of the collected waste liquids have been dumped into the ocean, and under the current situation where a global ban on the dumping of oceans is approaching due to the movement of environmental protection, the treatment of the waste liquids has become a serious problem.

In order to solve the above problems, efforts have been made to reduce the amount of waste liquid as much as possible, and, for example, low replenishment treatment and regeneration treatment have been actively researched and developed. However, it is still insufficient to reduce the amount of waste liquid, and another innovative method was desired.

On the other hand, with the spread of minilabs, the minilabs are becoming more and more dispersed, and the number of stores with a low throughput of 5 or less per day when converting 24 color negative films per day has increased. Although the temperature control time is long, the replenisher does not enter, and evaporation inevitably occurs, causing concentration of the processing liquid and lowering of the processing liquid level. If this happens, it will not be possible to maintain a constant processing performance.Therefore, water equivalent to the amount of evaporation is generally referred to as evaporation correction, and water is added manually at every start-up every morning or a fixed amount of water is added automatically. There is.

However, in the case of manual operation, it may be forgotten, and even if the environment is different, the method of automatically adding a fixed amount of water is not sufficient. As a technique for improving these, Japanese Patent Laid-Open No. 3-28
[0043] Although the use of a pressure sensor, a level sensor, and a concentration sensor is disclosed in Japanese Patent Laid-Open Nos. 4-11258 and 1-281446, it is still technically and costly. Not enough. It is an urgent task to solve the above problems at the same time as soon as possible.

Further, as a recent tendency, the shortage of human resources has been taken up as a serious problem also in the field of DP processing, and the need for a photographic processing device that requires as little human labor as possible is being sought.

[0008]

SUMMARY OF THE INVENTION It is, therefore, a first object of the present invention to provide an automatic processor having a substantially reduced amount of waste liquid.

A second object of the present invention is to provide an automatic processor which does not require evaporation correction work and can perform stable processing even under a low processing amount.

[0010]

(5) The automatic photographic developing machine according to any one of (1) to (4) above, wherein the pressure reducing means is 200 mmHg or less. (6) The automatic developing machine for photographs according to the above (1) to (5), wherein the heating means is a heat radiating portion of a heat pump.

The present invention will be described in more detail below.

The development processing section of the automatic processor of the present invention is not particularly limited and may be any one. Further, it may be for film development or for paper development, or may be in the form of a so-called film and paper common type automatic developing machine which has recently appeared. However, considering the installation environment of each automatic developing machine and the combination with the waste liquid processing mechanism that constitutes the waste liquid concentrating section, it is more effective to realize it with a developing machine in the form of a film and paper shared type automatic developing machine. .. Further, in the present invention, the photographic processing agent used in the automatic developing machine of the present invention may be in any form such as a liquid processing agent or a solid processing agent such as powder, granule or tablet. The tablet-like solid processing agent is most suitable in consideration of the stability, storage stability, and automation of replenishment operation. Also,
Even if the photographic processing agent is dissolved in advance and added to each photographic processing tank as a replenishing solution, the photographic processing agent is added to each photographic processing tank and the replenishing water is added to each photographic processing tank. It may be one. in this case,
It is preferable to use a tablet-shaped photographic processing agent.

In order to achieve the above-mentioned object, the photographic processing liquid processing apparatus, which is one of the constitutional requirements of the present invention, is preferably one capable of reusing the distillate generated in the waste liquid concentrating processing process. Evaporative concentrators are preferred. Further, as the heating means, a heat pump and a Peltier element having good thermal efficiency are suitable. A preferable processing condition for the evaporative concentration processing is that the processing temperature is 90 ° C. or lower, and more preferably 60 ° C. or lower. The processing pressure is preferably 200 mmHg or less, more preferably 100 mmHg or less. By performing waste liquid treatment with such equipment and conditions, there is no decomposition or volatilization of the substances contained in the waste liquid, a distillate that can be reused for photographic processing is obtained, and harmful gas and foul odor can be prevented. ..

The automatic processor of the present invention comprises (a) a development processing section, (b) a stock tank for storing a waste solution, (c) a waste solution processing section for evaporating and concentrating the waste solution, and (d) a distillate solution. It is preferable to have at least a stock tank, (e) a mechanism for supplying a distillate used for dissolving the treating agent, a replenisher, etc. from (d). As a result, photographic processing and waste liquid processing can be efficiently combined, and a kind of closed system can be constructed. With such a configuration, waste liquid processing is performed in accordance with development processing,
The resulting distillate can be used as a treatment agent-dissolving water or makeup water. Therefore, the amount of waste liquid discharged from the automatic processor can be extremely reduced regardless of the amount of replenishment. Further, it is easy to automate the dissolution of the treatment agent, the supply of the treatment agent, the replenishment of water, etc., and the labor required for the dissolution of the treatment agent, the supply of the treatment agent, the replenishment of water, etc. can be reduced.

Further, the evaporation correction is unnecessary by supplying the dissolved water and the replenishing water in an amount not less than the amount of evaporation and adopting the so-called multiple dilution replenishing system. This eliminates the need for a special means for evaporation correction, solves all the troubles, techniques, and costs, and stabilizes the processing of the low-processing automatic developing machine in which evaporation is a serious problem.
