Abstract

PURPOSE:To perform development processing without water piping for washing, to remove piping for a waste processing solution which is dangerous to the operation environment, and to improve the safety and to reduce in size by providing a solution supplementing device which detects the liquid level in a processing tank and supplements the processing solution. CONSTITUTION:Photographic processing tanks includes, for example, a coloring development tank CD, bleaching and fixing tank BF, stabilizing tank ST, etc., and stabilization processing employs washing alternative processing which eliminates the need for washing processing. The stabilizing tank 1 is linked to the stabilizing solution supplementing tank 2 through a passage 3 for the solution supplementing device for the stabilizing tank, and the solution is supplemented by a birds fountain system. Then, when the liquid level in the stabilizing tank 1 drops below a point A, i.e. the exit position of a stabilizing solution reservoir container 4, a supplementary solution is supplied from the passage 3, and the container 4 is raised above the liquid level in the tank 2 through a controller 5 while the processing solution is supplemented up to the position of the liquid level B and lowered after reaching a point B, thereby performing intermittent processing solution supplementation automatically.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to an automatic processor used for processing color photographic materials. More specifically, the present invention relates to an automatic developing machine for color photographic materials, which is substantially composed of processing tanks for color development, bleach-fixing, and stabilization processing, and has substantially no washing tank.

[Prior Art] In photographic processing, when the photographic light-sensitive material to be processed is for color, for example, steps such as color development, bleaching, fixing, washing, and stabilization are automatically performed. In some cases, bleach-fixing processing is performed in which both functions are provided in one bath.

In photographic processing, there is a method in which a processing tank such as a color developing tank contains a processing solution in an amount necessary for development, and a color photographic light-sensitive material is processed in a batch manner while being immersed in the processing solution in the tank. This method is generally called tank development or tank development. In this method, washing is carried out with standing water, but there is a drawback that the stability of the color dye is generally impaired, and the color developer becomes fatigued after two to three treatments, resulting in changes in color development characteristics. To compensate for this drawback, there is a method of processing while replenishing the consumed components due to fatigue, but it is difficult to stably process a large amount of color photographic material using this batch processing. To this end, it is common practice to continuously replenish the consumable components one after another while processing the photographic material to keep the processing solution components constant, thereby maintaining constant photographic performance.

g −M, n51z'**'1X4H'H:
I'll;l:34j*y - Durability of photographic pigments is also an extremely important characteristic, and it is now common knowledge to maintain this durability by thoroughly washing with water. It has become. Therefore, commercial continuous color photographic processing requires a large amount of water, has a large amount of water to drain, and allows for the supply and drainage of large amounts of washing water.

The location conditions were necessary.

However, recently, the price of municipal tap water has risen sharply due to the rise in water development costs, and sewerage drainage costs continue to rise. While this soaring price of water may be due to mere economic reasons, there are also situations in which supply cannot keep up with increasing demand in densely populated large cities.

In this way, water, which was once said to be infinite, has now become finite, and drought conditions are actually occurring in some parts of the world, leading to water supply restrictions. In such areas, there is a shortage of drinking water and washing water, and it seems extremely difficult to secure washing water for photographic processing.

In large cities, a water-saving society is forming, and it is no longer permissible to use multiple electric flushing water for photographic processing.

Generally, a desired size of work space is required around each of these automatic processors, in which operations such as adjusting the replenishment cock, correcting evaporation, replacing the processing solution, and dissolving the replenisher are performed. It is dangerous and undesirable in terms of the work environment to have water pipes for flushing water and pipes for drainage under the feet of these workers. Furthermore, when newly installing or relocating an automatic processor, piping work is always required, and such work requires time and money. For this reason, an automatic developing machine equipped with a printing liquid recovery tank is desired.

Furthermore, as another trend in recent years, automatic color development processing is shifting from large-sized laboratories to small-sized laboratory processing, and so-called mini-labs with small throughputs are rapidly emerging. In such small-sized laboratories, there is a strong desire for miniaturization of automatic processors. In the case of such small automatic processors, in addition to the requirement to omit water pipes for washing, it is also necessary to omit piping for discharging the processing liquid discharged from each processing tank to the sewer, etc. Therefore, it is desirable to reduce the capacity of the waste liquid recovery tank as much as possible. .

Then, a processing method in which stabilization treatment is performed immediately after bleach-fixing or fixing treatment without washing with water was proposed by the present applicant in Japanese Patent Laid-Open No. 5
No. 8-14834, No. 58-34448, No. 57-1
No. 32146 and No. 58-18631, etc., and clarify solutions to the above problems. However, as a result of research conducted by the present inventors, it has been found that this method has various problems. For example, since a large amount of water is conventionally used in water submerging, the prebath components that arrive on the photosensitive material and are brought in are considerably diluted. For this reason, the waste liquid could be directly discharged into rivers, sewers, etc., but when attempting to carry out the stabilization treatment, a large amount of pre-bath components would accumulate in the stabilization treatment liquid. Therefore, it is impossible to directly discharge this wastewater into rivers or sewers due to pollution laws and regulations. Therefore, it becomes necessary to pay a collection fee to a specialist in wastewater collection and processing to have the wastewater collected. Therefore, although the expense required for washing water is eliminated, a large amount of expense is required to dispose of the waste liquid.

In order to reduce such wastewater disposal costs, it is considered advantageous to reduce the amount of replenisher or actively evaporate the processing solution, but in this case, the difference between the amount of replenisher and the amount of evaporation of the processing solution is considered to be advantageous. It is difficult to maintain a balance, and not only can the liquid level in the processing liquid tank drop too low, resulting in changes in processing time, but it can also be eluted from the photosensitive material or brought in from the previous bath. The concentration of components that accumulate during
However, in extreme cases, precipitation may occur. As a result of research by the inventor of the wood, it has become clear that such inconveniences occur significantly in stabilization tanks, especially in water-washing alternative stabilization tanks.

[Problems to be Solved by the Invention 1] The present invention has been made in view of the above-mentioned problems, and firstly, it is possible to perform the developing process of an automatic developing machine without using water pipes for washing. t
t 61. 6゜, 2.3 □□□, ゎRemove dangerous treatment drainage piping to further improve safety. Thirdly,
It eliminates the need for piping work and makes relocation extremely easy.Fourthly, the treated υ1 liquid can be recovered, reducing environmental pollution. Sixthly, even if the wastewater collection tank for storing treated wastewater is made smaller, there is no need to increase the collection frequency; The technical challenge is to prevent the concentration increase and precipitation of accumulated components.

[Means for Solving the Problems] -2 The automatic developing machine for color photographic light-sensitive materials of the present invention for solving the technical problem is an automatic developing machine for color photographic light-sensitive materials having a processing tank including at least a stabilizing tank. The apparatus is characterized in that it has a liquid replenishing device that detects the liquid level in the processing tank and replenishes the processing liquid.

The system has a liquid recovery tank and is configured to store the waste liquid from the processing tank, and has at least two waste liquid recovery tanks, one of which stores the waste liquid from the color developing tank. The other tank is a tank (common tank) that mixes and stores wastewater from the processing tank with fixing ability and the stabilization tank, and the processing tank with fixing ability is It is a bleach-fix tank. Further, it is preferable that the color developing tank of the present invention is not provided with a heat exchange type cooling device using tap water, and that the processing temperature of the processing tank of the present invention is 30° C. or higher.

These processes are carried out in a color developing tank, a bleach-fixing tank, and a water-washing alternative stabilizing tank, and the liquid replenishing device of the present invention may be installed in one of these tanks, or in two or more tanks. may be provided. Most preferably, the liquid replenishment device of the present invention is provided for the stabilization tank.

An example of a liquid replenishing device preferably used in the present invention is shown in FIG.

In FIG. 9, 1 is a stabilizing tank, 2 is a stabilizing liquid replenishing tank which communicates with the stabilizing tank 1 through a passage 3, and 4 is a stabilizing liquid storage container using a bird's fountain system. In this embodiment, in addition to the configuration in which the bird's fountain system supplies replenishment liquid from the passage 3 when the liquid level of the stabilizing tank l falls below the point A, that is, the outlet [1 position of the container 4], The following configuration is adopted. That is, until the processing liquid is replenished to the position of the set liquid level B, the controller 5
The container 4 is raised to ]- from the liquid level in the tank 2 by
When reaching point B, the container 4 is lowered and restored to its original position. As a result, intermittent processing liquid replenishment is automatically performed depending on the amount of photosensitive material processed.

In this way, in addition to the bird's fountain system, it is preferable to forcibly replenish the processing liquid.

Each treatment liquid replenishment may be performed when the volume of the treatment liquid reaches 85% or less (more preferably 80% or less) of the full volume of the treatment liquid. Further, each treatment step (bath) in the present invention is most preferably a single bath, but does not necessarily need to be a single bath. 1) To increase the processing speed, there may be two or more baths, each bath may be connected and the liquid may freely flow in and out, or there may be a method in which the overflow circulates in a reverse direction called the anti-wetting method. It may also be a method in which they are tied together. Further, each processing liquid may be composed of a plurality of processing agents having different functions. For example, the first color developing tank and the second color developing tank are filled with processing solutions made of different processing agents,
In addition, the consumable components may be replenished separately, and the tanks may also be separated from each other. Also, regarding the stabilizing liquid, the first stabilizing liquid may contain an anti-piping agent as a main component, and the second stabilizing liquid may contain a surfactant as a main component. Of course, in this case,
Replenishment fluids are prepared separately and replenished separately. In the case of a "two or more" two-part processing tank configured to allow liquid to flow in and out as described in -1-, only when the processing steps are the same, the processing liquid of the entire [two or more split processing tank] Volume is 5

In addition, letters such as (a), (b), etc. indicate tanks filled with processing liquids of the same composition.

In each figure, solid lines indicate that the six tanks are substantially partitioned, dashed lines and one-way arrows indicate that adjacent tanks are connected in a white wave manner, and dashed lines and two-way arrows indicate that adjacent tanks are connected in a white wave manner. indicates that adjacent tanks are connected in such a way that they can mix freely. And the uppercase letters of A, B, C, as are 6
Replenishment liquids for the tanks are shown, and lowercase letters a, b, c, . . . indicate overflow liquids from the six tanks.

The preferred processing tank arrangement is as shown in Figures 1 to 8 above. In particular, the examples shown in Figures 4 and 5 are for color negatives and are characterized by the use of two types of stabilizing solutions; An example is shown in which the stabilizer is divided into a first stable liquid for the purpose of desalting components, and a second stable liquid for final drainage, exerting a bath-like effect and preventing uneven water droplets.

Regarding the first stable liquid, although the compactness is lost in the case of two tanks compared to the case of one tank, the amount of replenishment to obtain the same desalting effect may be extremely small. This is because the countercurrent method greatly improves the theory (11) effect.

The automatic processor of the present invention having these processing tank arrangements has a total capacity of 0.95% of the total amount of replenishing processing liquid for each processing tank.

8 times or less). The means for doing this is arbitrary, and for example, as shown in the examples below, the entire treatment tank is sealed using a moon panel, etc.
Each treatment tank may be evacuated using a loss-of-air fan to promote evaporation of the treatment liquid filled in each treatment tank. In addition, the temperature of each processing liquid was
High temperature treatment at 0°C or higher (preferably 33°C or higher),
Evaporation may be accelerated. Furthermore, total replenishment can be achieved, for example, by recycling some or all of the stabilizer wastewater and reintroducing it into the stabilization tank, or by using it as a processing solution in other processing tanks, such as a bleach-fix solution or a fixer solution. In order to reduce the total amount of waste liquid relative to the amount of treated liquid, 4j L i 6

Next, taking the configuration shown in Figures 1 to 8 above as an example, JJI
An example of a liquid recovery system will be explained. J in Figures 1 to 8
Jl liquids C and b (or C and g) and waste liquid a are collected and stored in a separate liquid collection tank. In this case, JJI liquids C and b may be collected and stored in the same grain liquid collection tank, or may be stored in separate rice grain liquid collection tanks. Figure 1~

It may be stored in the liquid collection tank of Section 2 C and b (or C and g), or it may be stored in a completely separate waste liquid collection tank.

The publication liquid recovery tank used in the present invention does not necessarily need to be built into the main body of the automatic processor; for example, it may be installed at the bottom of the main body, housed in a pedestal, or provided near the main body. , the present invention includes cases in which the external number of the main body can be specified.

In addition, in the automatic developing machine of the present invention having various tank arrangements as shown in -]-, the stabilizer is
-1 and the second stabilizing liquid tank 5T-2, the 4A liquid in the tank ST-1 which is closer to the processing liquid (bleach-fixing liquid or fixing liquid) having a fixing ability is used as the fixing liquid 45 Although it is preferable to mix it with a processing solution that has a fixing ability and store it (in one collection tank), both tanks 5T-1 and 5T-2 may also mix it with a processing solution that has a fixing ability and store it (in one collection tank). .

According to the present invention, for example, the processing liquid volume ratio of each processing tank is [C
D tank] : [BF tank] : [ST tank] −
[1,5~2.5] : [1] : [2~
3], and when the ST tank is divided into two or more, the volumes of the processing liquid may be approximately the same.

When replenishing the stabilizing solution, it is preferable to calculate the throughput and perform intermittent large-scale replenishment rather than continuous small-volume replenishment. For example, 70 to 120 sheets of color paper 8th edition (82mm x 117mm) (
It is preferable to carry out intermittent (sequential) large-scale replenishment by calculating the amount of 2-3 mJL per 8-plate sheet each time 80-100 sheets (preferably 80-100 sheets) are processed.

The processing amount of the photosensitive material can be calculated in any manner. For example, if the conveyance speed of the photosensitive material is kept constant and the width of the processed photosensitive material and the processing time are detected and calculated, the processed area of the photosensitive material can be obtained.

The stabilizing solution replenishment ratio in the present invention is, for example, [CD replenisher amount]: [ST replenisher speed] = [+]: [1 to 4]
, more preferably [11:[1,5-3].

The automatic developing machine of the present invention prevents stabilizer components from being carried into the color developing tank by adopting a method other than the endless belt method as a method of transporting the photosensitive material.
It is preferable to do so. The conveyance system preferably used in the present invention is disclosed in Japanese Patent Application Laid-open Nos. 51-60526 and 55-4874.

The processing liquid and the like used in each processing tank will be explained below.

Compounds that are preferably used together with ammonium compounds include acids, and sulfuric acid, hydrochloric acid, and the like are more preferably used.

The pH value of the stabilizer according to the present invention is preferably adjusted to 0.1 to 1O, preferably 2 to 8, more preferably p)I
A suitable range is 4 to 8.5.

The processing temperature during the stabilization treatment is preferably 30°C to 60°C, 3°C or more, preferably 5°C or more lower than the color developing tank, and more preferably 33°C to 60°C.
It is preferable to accelerate evaporation at a temperature of 38°C. In addition, from the viewpoint of rapid processing, the shorter the treatment time, the better, but it is usually 20 seconds to 10 minutes, most preferably 20 seconds to 3 minutes, and in the case of multiple tank stabilization treatment, the first stage tank can be used for a shorter time. It is preferable that the treatment time for the latter stage tank is long. In particular, it is desirable to perform the treatment sequentially with a treatment time 20% to 50% longer than in the previous tank. In addition, it is preferable to perform the stabilization treatment process in a multi-stage tank, and use a backflow method in which the replenisher is replenished from the final stage tank and sequentially flows into the previous stage tank, since the amount of replenishment can be reduced. After the stabilization treatment according to the present invention, there is no need for any water rinsing treatment, but rinsing with a small amount of water in a very short time, surface cleaning, etc. can be carried out as desired. In particular, it is preferable to wash the transport carriers such as endless belts and sorters for transporting photographic materials by rinsing them with a small amount of water (preferably standing water) or by wetting them with water using a sponge or the like.

When the bleach-fix treatment step of the present invention is followed by a direct stabilization treatment without substantially a water washing step, a short period of time for silver recovery between the bleach, white fix bath and stabilization feed is provided. Alternatively, rinsing with water or standing water may be provided.

Further, after the stabilization treatment, a draining bath containing a surfactant or the like may be provided, but preferably, a silver recovery bath, rinsing, draining bath, etc. are not provided. These additional treatments can also be done by spraying or painting.

In the present invention, the stabilizing solution and the ion exchange resin may be brought into contact with each other during the treatment. This can be done by placing the ion exchange resin in a cloth bag or the like and bringing it into direct contact with the stabilization tank where the photosensitive material is being processed, or by placing chemical fibers etc. in the resin column or filter case directly connected to the stabilization tank.

This means that the stabilizing liquid is taken out from the stabilizing tank, brought into contact with the ion exchange resin by a column method or a mixing method, and then at least a part of it is put into the stabilizing tank. show. In this case, putting it into the stabilization tank means the replenisher 4″, xns, =″t @
-c s h hs・0130 Filling System 211 Regardless of whether the liquid is ion exchanged in the circulation system or not, this liquid is returned to the stabilization tank again. The stabilized waste liquid thus regenerated can also be placed in a bleach-fix tank.

The ion exchange resin may be brought into contact with any tank in the case of stable supply in multiple tanks, but it is preferably treated in the tank immediately after the bleach-fixing process. More preferably, this treatment is carried out in two or more tanks, particularly preferably in all tanks.

In the case of one stabilizing tank, a preferred embodiment is to put the ion exchange resin in a resin column and directly connect it to the stabilizing tank. In the case of two tanks for stable supply, a preferred embodiment is to place the ion exchange resin in a resin column or filter case, and directly connect and contact the 1st tank immediately after the bleach-fixing process, and more preferably to contact the 2nd tank 11 in the same manner. let In the case where the stable supply is 3 or more tanks, a preferred embodiment is to directly connect and contact the tank 11 immediately after the bleach-fixing process as described above, and more preferably, the stable supply in tanks other than the first tank is These six tanks are directly connected and in contact with each other. As mentioned above, it is most preferable to directly connect the ion exchange resin and the stabilizing solution to the stabilizing tank, but if there is not enough space to install the resin column and filter case in the automatic processor, overflow or increase the amount of replenishment may be necessary. It is also possible to bring the stabilizing solution forcibly removed from the stabilizing tank into contact with the ion exchange resin and return it to the stabilizing supply. When one stabilization tank is used, the stabilized liquid taken out is brought into contact with an ion exchange resin using a resin column, and the stabilized liquid after contact is returned to the stabilization tank. In this case, it is preferable to add the stabilizing liquid component after contact. If there are two or more stabilizing tanks, the overflow and resin column are used to contact the ion exchange resin from the foremost tank near the bleach-fixing process, and the product is returned to the stabilizing tank on the drier side.

In this case, it is desirable to add back the stabilizing liquid components.

Furthermore, although it is possible to reuse the stabilizing solution after contact with the above-mentioned ion exchange resin as a replenisher, in this case it is desirable to add a stabilizing solution component.

In addition, it is preferable that the above-mentioned ion exchange resin be brought into contact with a stabilizing solution, then brought into contact with a bleach-fix solution, and then regenerated. Especially in the case of an anion exchange resin, silver recovery can also be performed by regenerating the resin, which is effective. big.

The case where the stabilizing solution is brought into contact with the ion exchange resin has been described above, but this is not limited to electrodialysis treatment (see Japanese Patent Application No. 59-96352) and reverse osmosis treatment (Japanese Patent Application No. 59-96352).
96350) etc. can also be used.

In the present invention, a conditioning tank may be provided after the color development process, and the conditioning tank is used to stop the development and accelerate the bleaching reaction, thereby preventing the developer from being mixed into the bleach-fix solution. The conditioning bath contains, for example, a bleaching agent and a buffering agent to help reduce the negative effects of bleaching. As the bleaching accelerator, organic sulfur compounds are generally used, including mercapto compounds and thione compounds. Furthermore, acids and alkaline agents such as acetic acid, citric acid, succinic acid, sulfuric acid, and sodium hydroxide are used to adjust the pH of the condidigoner.

The amount of these bleaching accelerators and buffer agents used ranges from 0.001 g to 100 g per 1 liter of conditioner. In addition to the above additives, chelating agents and the like may also be added. This conditioning tank is also preferably configured to have a processing liquid volume of 50 cubic feet or less.
