Description

[Detailed description of the invention] (Industrial field of application) The present invention is a hanging film in a device that automatically wraps the fed film in a suspended state around the developing tank and develops the film by sequentially moving it through each processing tank. Regarding a conveyance device.

(Prior art) In a conventional automatic processing machine, a hanging film transport device, in particular an FD (First Develop), which sequentially moves each processing tank for development processing while the film is suspended from a hanger. In the development process of so-called reversal film, in which a single lifting device is directly connected to a main body moving device equipped with a main body lifting device, and these are operated in a series of fixed cycles, the film is fed in by an automatic feeding device. The hanging film is supported by a hanger holder of a single FD lifting device that moves up and down, and placed in the first developer tank, and is moved within the first developer tank in a series of fixed cycles by the main body moving device. The hanging film is pulled up from the first developing tank by the lifting operation of the main unit's lifting device, and immersed into the next processing tank by the lowering operation. The film was immersed in a processing tank and transported to a drying room, where the hanging film was automatically developed.

(Problem that the invention aims to solve) In this way, conventional automatic processing machines are designed to be transported in a fixed cycle based on the appropriate exposure at the time of shooting, so there is no possibility of overexposure or underexposure during shooting When developing a certain film, it is developed in an inappropriate state, with either too much or too little. Conventionally, in order to correct this excess or deficiency during the development process, the FD is dipped into the first developer tank by a single lifting device and moved within the tank. I was gone. That is, the hanger on which the film is being moved by the main body moving device is manually picked up and removed from the receiving portion, and if the exposure is insufficient, the hanger is moved back and placed on the receiving portion at the rear of the moving device. The time taken by the moving device to move within the first developing tank is increased, and in the case of overexposure, the first developing tank By shortening the travel time in the developing tank,
Previously, desensitization processing was performed, but this manual operation involved fumbling around in a darkroom, making it even more complicated, and there were problems such as poor processing efficiency. The idea is to solve this problem.

(Means for Solving the Problems) In order to achieve the above-mentioned object, the present invention provides a transport device for an automatic film processing machine in which film is suspended from a hanger and is sequentially immersed in each processing tank for development processing. , an independent elevating device for transporting the main body up and down into the first developing tank is installed separately from a main body moving device combined with an elevating device for the main body spanning each processing tank, and this independent elevating device and the first developing tank An independent moving device is provided between the main body moving device and the main body moving device to move the hanger receiver in the conveying direction independently of these devices, and this independent moving device is driven separately from the independent lifting device and the main body moving device. By configuring the hanger in series, it is possible to adjust the length of time the film hanger is moved by the independent moving device corresponding to the first developing tank, and the increase in the length of time during which the hanging film is developed in the first developing tank can be adjusted. , which performs a desensitization process.

Moreover, this independent moving device can also be constructed by constructing a moving frame in which a hanger receiver provided on the upper part moves circularly in the conveying direction.

(Function) The independent lifting device is installed separately from the main body moving device combined with the lifting device, and the independent moving device provided between the two is configured to be driven independently of the main body moving device. It becomes easy to drive the movement cycle of the independent moving device in one developing tank by changing the movement cycle of the main body moving device in another processing tank, and the moving speed of only the independent moving device in the first developing tank can be changed. You can easily adjust the speed.

Therefore, the hanger on which the film is suspended is received by the independent moving device from the independent lifting device and suspended in the first developing tank to be immersed, and the length of the transfer cycle of the independent moving device to the main body moving device is adjusted. Thereby, the immersion time of the film in the first developing tank can be adjusted as appropriate.
