Next, with respect to the hanger 1, the number of pieces or the number of sheets is measured by a sensor 8, and the total area of the film F is calculated by an arithmetic unit. Subsequently, the hanger 1 advances to notches (d), (e)..., drawn up by a command from a control system, and fed to the next tank. When said area reaches an area which is prescribed by a processing capability of the tank, a replenishing device operates and replenishes automatically a component required for the treating liquid, into the tank.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a method for managing processing liquids when developing various films.

(Prior art) When developing a film using a developing device, for example, 13
5 (35m>, 120.220 type, etc., and sheet films such as 4 x 5 size, 5 x 7 size, etc.) are processed in the same process. Workers replenish the processing solution estimated to be necessary based on their experience based on the type and number of films being processed.Processing usually involves the use of a first developer, a reversal solution, and a reversal solution. Seven liquids are used: a color developing solution, a cleaning solution, a bleaching solution, a fixing solution, and a stabilizing solution, but replenishing each of these as necessary requires skill and tension. At present, no technology for managing processing liquids in the development process has been disclosed yet.

(Technical Problem) The present invention was developed in view of the above points, and its purpose is to grasp the state of the processing liquid by accurately knowing the processing area even if the film type is 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 present invention achieves the above object by moving a film hanger to which each film of the same screen size is attached in the longitudinal direction of the film, and measuring the number of films or sheets using a number sensor and accumulating the number of films. A film characterized in that it includes a step of calculating the total area of the film, and a step of activating a replenishing device when the result of the opening reaches a certain area to replenish the developer and other necessary components. This is a method for managing processing liquid during development.

In the above method, if the film hanger is for 135, only 35#1III size film is attached (however, it does not matter how many shots are taken). This determines the width of the film required 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 transmitted to a computing device such as a microcomputer or computer. It is possible to automatically process the data.

In the calculation step, in order to know the processing area of the film, the number of films or sheets is measured, and the area is calculated by multiplying that 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 rolls or sheets, 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 a calculation device, the number of films is calculated from the known film size, these are integrated, and the 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 below the developer. - Operates to replenish each component individually by command signals issued from the control system. Considering the effect on the film, replenishment of the necessary components should be carried out to the tank when the film hanger is moved between processing tanks, preferably immediately after leaving the tank, and the replenishment should be carried out to correspond to the above-mentioned fixed area. A predetermined amount is put in, and as a general rule, no replenishment is done in between.

(Function of the invention) In the method of the present invention, the number of frames of films hung by size on a film hanger is measured by a number sensor, so even if films of different sizes are mixed and processed for each hanger, 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 regarding 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 stabilizer, 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, and 3 is a in the figure for receiving the film hanger.
The locking notch 4 provided at the position of ~i is a moving member for advancing the film hanger, and has a support arm 5 for the hanger shaft, and by rotation of the arm 5, the film hanger is transferred to the next locking notch 3. 6 is the first developer tank; 7 is a type sensor provided in the notch at position C; 8 is a number sensor provided above it; 9 is a sensor for raising the film hanger 1 in the longitudinal direction of the film, and It is an elevator for transferring to the support arm 5, and has a sprocket 9a.

The hanger shaft is locked by a locking piece 10 attached to the chino 9C between 9b and activated by a detector 11 installed at the C position.

As shown in FIG. 3, the film hanger 1 has a mounting frame 13 for the film F suspended below the hanger shaft 12.
It has a classification piece 14 attached to the end of the hanger shaft 12 that is locked in the locking notch 3, and the type of film is distinguished according to the manner in which the small hole 15 formed therein is formed. 16 is a floodlight, 17
is a light receiver, and the sensor with this configuration is the type sensor 7.
, the sheet number sensor 8, and a means for detecting development processing conditions 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 conditions such as ten-and-a-half aperture, +1/3 aperture, -half aperture, etc. can be given by the combination code of the small holes provided in the classification piece 14, and the development 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 shown in FIG. 3 has three light emitting and light receiving sets, the total number of combinations is seven, and with the addition of one without holes, it can be used to discriminate eight types of film, and these are allocated as shown in Table 1.

In addition, the 135 type with 24 shots and 12 shots is 135.
-20.

The codes for the sensitization and desensitization conditions in Table 1 can be created in exactly the same way, but since there are many conditions due to strict correction, it is better to combine four small holes and divide them into 16 stages.

In the number sensor 8, a projector 21 and a receiver 22 are installed 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 hung from each hanger is first set in the notch at position a on the hanger support member, and after the sensitization conditions set for that film group are read here, The arm 5 of the moving member advances the hanger to the notch C through the next position, and the type sensor 7 reads the information on the type piece 14 to determine the type of film in the group of films suspended from this hanger. The hanger 1 passes a sheet number sensor 8 by means of an elevator 9 operated by a detector 11 that detects its progress to this position, and the number of sheets or sheets is measured for each film by the sensor 8 at the gate. 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, so the calculation device calculates the total area of the film that has passed through the number sensor 8. , are integrated as needed, and the results are input to a comparator and compared with the ability of a processing solution such as a first developer that can be processed in a first developer tank or the like.

The sensitization 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 it is calculated according to the sensitization and desensitization conditions input to the calculation device. It is necessary to correct the area values.

The elevator 9 advances the hanger 1 to the notch in the position lid, and each arm 5 sequentially sends the hanger 1 to e, f, etc., but the position to which it is sent is determined by a command from a control system linked to a computing device. At the determined position, the developer is pulled up from the first developer tank by a lifting means (not shown) and sent to the next tank, for example, a reversing tank, and the other tank is also processed by the same means and method. As a result of the comparison, when the total area of the various films that have passed through the first developer tank reaches a certain area determined by the processing capacity of the tank, or a set value of some percentage thereof, a signal is sent to the replenishing device. is emitted, and each tank such as the first developer tank is replenished with necessary components. The timing of this replenishment is such that 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 by taking into account the type and number of films can be carried out automatically without any manual intervention. In particular, the method of the present invention suspends the same film on each film hanger and detects the type of film on the hanger and the number of films obtained by the number sensor. Since the total area is determined by the number and length of sheets, an accurate value can be obtained, and based on this, calculation processing is performed and the necessary components are individually replenished into the 8 tanks, so there is no waste of stock solution, and the current @
We were able to improve accuracy.
