2. Description of the Related Art In recent years, as the number of people who enjoy photography has increased in many countries around the world, the production volume has increased. It is important to sort small-volume production varieties as much as possible, and to increase the operating time of equipment for mass production as much as possible to reduce costs and rationalize in order to improve production efficiency. When constructing such production equipment, it is important to reduce the equipment investment by increasing the operating efficiency of each equipment as much as possible, reduce the initial investment, and reduce the running cost. From this point of view, when looking at the chemical preparation process used in the photosensitive material manufacturing plant, the photographic light-sensitive material uses a large amount of chemicals in a specific layer; They are made at the same time; each chemical has an expiration date; it is a very special field where photographic performance is adversely affected if even small amounts are mixed together.

To produce a certain type of photographic light-sensitive material,
It is necessary to apply a coating liquid of at least two or more layers of the photographic light-sensitive material that composes the variety on the support, and to prepare the coating liquid of each layer, it is necessary to prepare a dozen or more kinds of chemicals. A chemical solution is prepared, stocked, and mixed and prepared, but many chemical systems must be replaced every time, although the chemicals used differ depending on the variety and there are some common chemicals. In recent years, with the expansion of applications in the sensitive material market, the production of small-quantity, multi-product types has increased, and in order to frequently respond to chemical changes, manual work is required to shorten the changeover time, reduce capital investment, We have been striving to improve product response capabilities. However, the number of work mistakes increases due to manual work, and it takes time if the check function is enhanced to prevent mistakes, the production efficiency is lowered due to the need for manpower, and the labor cost is increased. In addition, the chemical liquid of the chemical received in the stock tank,
In order to distribute each layer constituting a photographic light-sensitive material, JP-A-1
The automatic pipe switching device described in Japanese Patent Publication No. 0-47600 has been used to speed up the work and prevent mistakes. However, as the market needs diversify as described above, the number of product types increases, and In accordance with the model change of the sensitive material, it is necessary to modify and expand such equipment, and it is becoming a method that is not so suitable for the small-quantity, high-mix-age era.

EXAMPLES The present invention will be described below with reference to examples, but the present invention is not limited thereto. Example The equipment shown in FIG. 1 is shown as a reference example of the present invention. First, in the chemical liquid preparation tanks shown in 2 (a, b, C), chemical liquids of different chemicals A, B, and C are prepared, and after the preparation is completed, filtration treatment is performed and 3 (a, b, C
Transfer to one of the chemical solution stock tanks shown in C and d). According to the manufacturing start signal, this chemical liquid is added with the chemical liquid addition tanks 4 (a, b, c, for preparing liquids required for using the respective chemical liquids at the same time or in the same production lot).
The various chemical solutions prepared are supplied to d, e, f, g, h) using the automatic dispensing device 7. During the preparation in such a chemical solution preparation tank, the preparation of the chemical solution required for the next production variety is started.For example, the chemical solution currently in use is the chemical solution stock tank 3
If it is a, 3b, 3c, it is supplied to the vacant 3d after the filtration process, and when the preparation of the chemical solution addition tank of the current product is completed,
In order to receive the necessary chemicals for use in the next variety,
After cleaning the chemical stock tanks 3a, 3b, 3c, and after cleaning,
The chemical solutions prepared in the chemical solution preparation tanks 2a, 2b, 2c are filtered and transferred to the chemical solution stock tanks 3a, 3b, 3c, respectively, and the minimum number of chemical solution preparation tanks for the four types of chemicals required for the next variety The solution is prepared by dissolving and the liquid is switched in a short time. Although the number of chemical solution preparation tanks, chemical solution stock tanks, chemical solution addition tanks, etc. is limited in the present embodiment, in practice, it is not such a small number, and an effect can be exhibited in a system composed of more tanks. I can.

As described above, the method and apparatus for distributing a chemical solution for a photographic light-sensitive material according to the present invention are: 1) In order to prevent work mistakes, automatic pipe switching prevents mistakes during pipe connection (destination at the time of connection). , Leakage due to poor piping connection, etc.) was attempted. 2) For rapid switching, the introduction of an automatic switching device enabled simultaneous switching. 3) Regarding the handling of multiple types and the minimization of equipment remodeling, the maximum number of products produced by the target blunt can be achieved by giving flexibility to supply from the chemical solution preparation tank to the chemical solution stock tank and from the chemical solution stock tank to each layer emulsion preparation system. By installing the number of equipment that can handle chemicals, it is possible to achieve an effect that it can be used in any combination.
