Description

[Detailed description of the invention]

(Industrial Application Field) The present invention relates to a method for managing processing liquids when developing various films. (Prior art) When developing film using a developing device, different types (sizes) such as roll film such as 135 (35 mm), 120, and 220 types, and sheet film such as 4 x 5 size and 5 x 7 size are used. In the past, workers had to make judgments based on their experience based on the type and number of films and replenish the processing liquid they estimated was necessary. In the case of reversal film, processing usually involves a first developer, a reversal solution, a color developer, a cleaning solution,
Seven solutions are used: a bleaching solution, a fixing solution, and a stabilizing solution, and skill and tension are required to replenish each of these as needed. However, at present, no technology has been disclosed for managing processing liquids in a developing process involving a mixture of various films. (Technical Problem) The present invention was developed in view of the above points, and its purpose is to grasp the condition of the processing solution by accurately knowing the processing area even when the types of films are different, and to extract the necessary components in a timely manner. It is an object of the present invention to provide a method for managing a processing solution in film development, which eliminates waste of the stock solution and improves the accuracy of development by replenishing the solution. (Technical means) The purpose of the first stage is to set a film hanger hanging films of the same screen size at a predetermined position along the development line, and to increase or decrease the type of film from the type piece provided on the hanger, as well as from the information piece. A process of reading the film specifications, a process of moving the film using a hanger moving means installed along the development line, a process of moving the film hanger in the hanging direction before development, and measuring the number of films or sheets using a number sensor. At the same time, the process of calculating the total area of the film by integrating it, correcting the stated area according to the specifications of the increase/decrease sensitivity, and comparing and estimating the result of this calculation with the processing capacity of the processing liquid set in advance, determines the timing of replenishment. This can be achieved by a configuration that includes the steps of determining: and, in accordance with the determination, operating a replenishing device when the film is not in the bath to replenish the developer and other necessary components. In the above method, the film hanger is 135
If you are using the camera for business purposes, install only 35mm size film (however, it doesn't matter how many shots you take). This determines the width of the film necessary to calculate the film area, and although the film may be different for each hanger, it is necessary to hang only films of the same screen size on one hanger.
In this embodiment, several holes are provided on the side of the film hanger, and the presence, location, and number of holes are used as information to identify the film. According to this method, the read information is sent to an arithmetic device such as a microcomputer. Automatic processing is possible. In the calculation step, the number of films is measured in order to know the processing area of the film, and the area is calculated by multiplying the measured value by the film width known in the previous step. In this process, it is necessary to move the hanger and the film in the longitudinal direction of the film, and the sensing method does not matter, but when using a transmitted beam as in the example, infrared rays etc. Use it and do not let it emit light except when necessary. In addition to the above-mentioned methods for measuring the number of films, it is also possible to directly measure the length from the number of rotations by bringing a rotating roll into contact with the film, or to calculate the length from the speed and time. Since it is a film, a non-contact type is preferable. The measured values are sent to an arithmetic unit, the number of films is determined from the known film size, these values are integrated, and this value is compared with a fixed area determined by the processing capacity of the processing liquid in the developing tank or the like. The replenishment process is a process of replenishing each processing solution with necessary components when the total area of the film calculated by the above process reaches a certain area that can be processed with each processing solution including the developer. - Operates to replenish each component individually by command signals issued from the control system. Considering the effect on the film, replenishment of necessary components should be carried out when the film hanger is moved between processing tanks, preferably immediately after leaving a certain tank, and the replenishment should be carried out to correspond to the above-mentioned fixed area. A predetermined amount is added to the tank, and as a general rule, no replenishment is performed during that time. (Function of the Invention) In the method of the present invention, the number of frames of film hung by size on a film hanger is measured by a number sensor, so even if films of different sizes are mixed and processed, the total number of frames is It is easy to synthesize as an area, and it is easy to obtain accurate values. Once the processing area for a mixture of different types of films is obtained in this way, it is possible to decide which processing solution to replenish the necessary components and how, based on known data on the components consumed in each processing solution. can. In the present invention, necessary components are replenished when the total processing area of the film reaches a certain value, so replenishment can be carried out while keeping an eye on the overall balance from the first developing solution to the stabilizing solution, thereby improving the quality of management. It also improves. (Example) Examples will be described below with reference to the drawings, but the present invention is not limited thereto. <Mechanical Configuration> Figures 1 and 2 illustrate a part of the mechanical configuration of the developing system that implements the present invention. The parts are illustrated. In the figure, 1 is a film hanger, 2 is a hanger support member provided along the development line, 3 is a locking notch provided at positions a to i in the figure to receive the film hanger, and 4 is a movement for advancing the film hanger. The member has a support arm 5 for the hanger shaft, and the arm 5
It is transferred to the next locking notch 3 by the rotation of . 6 is the first developer tank, 7 is the type sensor provided in the notch at position c, 8 is the number sensor provided above it, 9
is an elevator that raises the film hanger 1 in the longitudinal direction of the film and transfers it to the support arm 5 of the first developer tank 6, and the hanger shaft is locked by a locking piece 10 attached to the chain 9c between the sprockets 9a and 9b. It is activated by the detector 11 provided at position c. As shown in FIG. 3, the film hanger 1 has a mounting frame 13 for the film F suspended below a hanger shaft 12, and a type piece attached to the end of the hanger shaft 12 that is locked in a locking notch 3. 14, and the type of film is distinguished by the manner in which the small holes 15 formed therein are formed. 16 is a light emitter, 17 is a light receiver,
The sensor having this configuration can be used as the type sensor 7, the sheet number sensor 8, and the developing processing condition detection means described below. The development processing conditions are sensitization and desensitization development, and the sensitization and desensitization conditions are also read by providing an information piece on the hanger shaft, such as + half aperture, +
Conditions such as one-third aperture, -half aperture, etc. can be given by the combination code of the small holes provided in the classification piece 14, and the developing time can be controlled. 18 is the information piece, and 19 is a reading sensor. A large number of information pieces 18 are prepared depending on the type of sensitivity increase/decrease specifications, and are detachable and replaced. A code consisting of a combination of several small holes is made as follows. Since the sensor 7 in the example of FIG. 3 has three transmitting and receiving sets, the total number of combinations is seven, and with the addition of non-porous one, it can be used to discriminate eight types of film, and these are allocated as shown in Table 1. In addition, 24 shots of 135 type, 135 for 12 shots
Treated as -20.

[Table] (Note) ○: Perforated: No hole Codes for sensitivity increase/decrease conditions can be created in exactly the same way, but since there are many conditions due to strict correction, four small holes are combined and divided into 16 stages. It's good. In the sheet number sensor 8, a light emitter 21 and a light receiver 22 are provided facing each other in the width direction of the film hanger 1, but the number of films that can be hung on the hanger varies depending on the type of film, so for example, When using other sizes, operate only the necessary floodlights. An infrared light emitting diode is used as a light emitter, and a phototransistor is used as a light receiver. Emission of light is prohibited except during detection or measurement to ensure that the film is not affected. In addition, the oval-shaped chain line between positions ab and de in FIG. 2 indicates the rotation locus of the arm 5. <Management method> The same type of film is hung from each hanger and is first set in the notch at position a on the hanger support member, and after reading the sensitization and desensitization conditions set for that film group, The arm 5 of the moving member advances the hanger to the notch c through the next position b, and the type sensor 7 moves the hanger to the notch c.
The hanger 1 is moved past the sheet number sensor 8 by an elevator 9 operated by a detector 11 that reads the information of 4 and determines the type of film in the group of films hung on this hanger, and detects the progress to this position. During this time, the sensor 8 measures the number of films for each film. The output from the type sensor 7 determines the width of the film, and the output from the number sensor 8 determines the length of the film.
In the arithmetic unit, the total area of the film that has passed through the sheet number sensor 8 is calculated and integrated at any time, and the result is input to a comparator to apply a processing solution such as a first developer that can be processed in a first developer tank or the like. Comparisons are made with the capabilities of The sensitization and desensitization conditions determine the development time, that is, the time the film stays in the first developing tank, and therefore the degree of fatigue of the developer varies depending on these conditions, so the sensitization and desensitization conditions are It is necessary to correct the calculated area value. The elevator 9 advances the hanger 1 to the notch at position d, and each arm 5 sequentially sends it to e, f, etc., but the position to be sent to is determined by a command from a control system linked to a computing device, and At a predetermined position, the first
It is pulled up from the developer tank and sent to the next tank, for example, an inversion tank.
This tank is also treated using similar means and methods. As a result of the comparative weighing, when the total area of each type of film that has passed through the first developing tank reaches a certain area determined by the processing capacity of the tank, or a set value of a percentage of that area, replenishment is performed. A signal is issued to the device, and each tank such as the first developer tank is replenished with the necessary components. The timing of this replenishment is when the film is not in the bath, and more specifically, immediately after it is lifted from the bath. (Effects of the Invention) Since the present invention is constructed and operates as described above, the conventional work in which an operator replenishes each film based on the type and number of films can be performed automatically with almost no human intervention. In particular, the method of the present invention suspends the same film on each film hanger, and detects the type and number of films on each hanger using a sensor. Since the total area is determined based on the number of films or their length, an accurate value can be obtained, and based on this, calculation processing is performed to replenish the necessary components to each tank individually, so there is no waste of stock solution. Therefore, the development accuracy could be improved.
