BEST MODE FOR CARRYING OUT THE INVENTION The method and apparatus for preparing a chemical solution for a photographic light-sensitive material of the present invention will be described in detail below. The means for dealing with the current problems will be explained. As a means for solving the above problems, a chemical solution preparation tank and a chemical solution stock tank are configured in a one-to-one manner, and the chemical solution preparation tank includes a stirring / mixing means such as a stirrer, and a temperature control means if necessary. The chemical liquid stock tank has a stirring / mixing means as necessary, a temperature control means as necessary, and an instrument for controlling the amount of liquid in the tank. Transfer control of the liquid in the chemical liquid preparation tank To enable.

Separately from this, the production control system instructs the end of the current product, and after cleaning the chemical solution stock tank, automatically prepares the chemical solution prepared in the chemical solution preparation tank at the stage when the type of the next production item is set. It is also possible to transfer to a chemical solution stock tank and prepare for the production of the next product. Further, when the chemical prepared in the chemical solution preparation tank is sent to the chemical solution stock tank, it is usually filtered, but this filtration can be carried out by gravity or filtration using a transfer means such as a transfer pump. After transfer-filtration, it is possible to wash the filtration equipment at the same time as the chemical preparation tank, to wash the filtration equipment at the same time as the chemical stock tank, or to wash the chemical preparation tank and the chemical stock tank independently. It is possible. If the chemicals in the chemical preparation tank are different from the chemicals in the chemical stock tank, you can use by washing as described above, or you can use multiple liquid transfer systems, each with its own filtering device, and attaching and detaching the filtration filter. It is also possible to have a degree of freedom.

Further, the method and apparatus for preparing a chemical solution for a photographic light-sensitive material of the present invention is an improvement on the following matters. [1] Improving detergency for eliminating contamination of chemicals When a chemical preparation system is used in common, adverse effects on the photographic light-sensitive material due to residual chemicals prepared before become a problem. As a means for solving such a problem, in order to improve the smoothness of the inner wall of the tank, for example, buffing # 400 or more is performed, and the blades immersed in the liquid, the sensor, etc. are welded so as not to have a gap structure. A general method is known.
Further, in order to improve the cleaning property, methods such as chemical cleaning, solvent cleaning, immersion cleaning, high pressure cleaning, and low surface tension of the inner surface of the tank are known, and the effect is sufficient for tank cleaning.

However, the problem that occurs in the actual system is not such a part that is easy to wash, but a connection part of piping,
It is a pump used for liquid transfer or a filtration device for filtering and separating. In order to improve the cleanability of such parts, the number of pipe joints from the chemical preparation tank to the chemical stock tank should be reduced as much as possible to reduce the amount of penetration into the gap of the connection part. After cleaning the liquid transfer system of the preparation tank and the stock tank normally in synchronization with either the preparation tank or stock tank, or separately from the preparation tank and stock tank, from the preparation tank to the stock tank. The pipe portion is filled with the cleaning liquid for 10 seconds or longer, preferably 1 minute or longer, the chemical liquid that has penetrated into the gap due to diffusion is eluted, and the filling liquid is discharged. The same operation is repeated n times (n> 1) to wash and prevent contamination. By cleaning with a liquid that is highly soluble in various chemicals, the cleaning time is shortened and the amount of cleaning liquid used is reduced. Specifically, water, warm water, organic solvents, chemical cleaning agents, etc. are effective. In the case of an organic solvent, cost performance is important, and generally inexpensive methanol or ethanol is generally used. Further, in the case of a chemical cleaning agent, a method of increasing the solubility by reacting with an object to be cleaned, a strong alkali,
A method of decomposing with an enzyme, a method of dissolving and removing by using the solubilizing ability of a surfactant, a method of dissolving a substance to be washed in oil with a two-phase emulsion and removing it are also common.

[2] In order to use a chemical solution preparation tank for increasing the variable range of the preparation scale of the chemical solution for many purposes in general preparation of the chemical solution, since each chemical solution naturally has a different usage amount, each preparation tank has its own preparation tank. Although it must have a function of adjusting the preparation scale corresponding to the chemical solution, the conventional stirring and mixing device could be used only up to about 1/3 of the maximum scale due to problems such as foam generation and stirring and mixing efficiency. .

EXAMPLES The present invention will be described below with reference to examples, but the present invention is not limited thereto. Example 1 In one step of manufacturing a color photographic light-sensitive material, the total number of chemicals used by the following types, the number of chemicals common to these types, and the approximate production time of each type are shown.

[0026]

[Table 1]

In such a production item, a maximum of 25 chemical preparation systems shown in the above table are provided for chemicals, and as an example of the embodiment shown in the present invention, a chemical preparation tank having a stirrer is provided in 20 series, and further, A chemical solution preparation tank with a stirrer having a temperature control function is provided in 5 systems, and a chemical solution stock tank corresponding to the chemical solution preparation tank is provided with a system with an agitator
Liquid level monitoring function for a total of 25 systems with 5 systems with temperature control function and 15 systems for chemical stock tanks only (D
/ P cell, differential piezoelectric transmitter), gravity transfer method is used as the transfer method from the chemical solution preparation tank, filter mesh filter specified for each chemical is used as the filtration method, and two types of filters are installed in parallel. It was confirmed that it is possible to work on a daily basis by two people using the mechanism that can be automatically switched, and to work five days a week. In addition, product E, which has a short operating time,
In B etc., the types of chemicals in the chemical solution stock tank and the chemical solution preparation tank are different. After the chemical solution preparation tank → chemical solution stock tank transfer, it is independent of the chemical solution preparation tank washing and used at a timing with sufficient work time Remove the filter, wash the filter section, and set the filter for the next chemical at any timing from the time when the chemical solution preparation tank after the cleaning is completed to the time when the solution is transferred to the chemical solution stock tank. I used it, but it was possible to use the system without any problems due to contamination.

[Example 2] When a color photosensitive material consisting of 15 layers is manufactured for 7 days using a system in which 30 chemical solution preparation tanks and 30 chemical solution stock tanks are configured in a one-to-one manner, preparation until the start of production Since each time had its own chemical solution preparation tank, the work crew could handle it without overtime in one day.
In addition, 5 kinds of chemicals used in large quantities and 6 kinds of chemicals with a short quality guarantee period of chemicals needed to be re-prepared during manufacturing, but 4 kinds of preparations were required in the same preparation tank. However, in the method of the present invention, the liquid chemical preparation tank was empty, and it was possible to prepare at the required timing, and the substantial preparation time was one day shift. In addition, the cleaning time and the amount of cleaning water (cleaning solvent) used for such a system do not require elaborate cleaning because the same chemicals are manufactured continuously, and it takes about 10 minutes to clean one tank (CPI, Cleaning In
Place, about 3 minutes, drainer 7 minutes), by starting the cleaning immediately after the transfer from the chemical solution preparation tank to the chemical solution stock tank, the overall cleaning time could be completed in about 2 to 3 hours. . Also, the amount of wash water used is about 4
Completed at t.

Comparative Example Preparation of the same chemical liquid as in Example 2, that is,
A chemical solution was prepared when a color light-sensitive material consisting of 15 layers was produced for 7 days. However, instead of the chemical liquid preparation device of Example 2, one chemical liquid preparation tank of 300 liters and five chemical liquid stock tanks connected to the six chemical liquid preparation system 6 systems (the scale of the chemical liquid preparation tank differs depending on the system) The conventional drug preparation system was used. As a result, the preparation time required 2.5 days (day shift + 3 hours overtime) due to the restriction of the chemical solution preparation tank. Further, the re-preparation of the above-mentioned 5 types of chemicals used in large amounts and 6 types of chemicals having a short quality guarantee period of the chemicals required 1.5 days of preparation time. On the other hand, when comparing the amount of (cleaning solvent) used, various chemicals are prepared in one chemical solution preparation tank, and one tank is used for cleaning the necessary parts to prevent quality deterioration due to mutual contamination. It took about 60 minutes on average and about 1 day in total. In addition, the amount of wash water required was about 13 ton of wash water (+ wash solvent).
