Abstract

PURPOSE:To simplify full automatic carrying of a photosensitive material by rotating half the tip part of the photosensitive material left in a guidance tool so that it can be removed automatically. CONSTITUTION:A guidance tool 15 moves with an endless belt 14, and stops temporarily in a photosensitive material inserting part by a projection of a stop member 20 by a detecting member 19 and a solenoid 21. A pring paper 16 is fed by a feed roller 17, engaged by a notch 16b of a tip 16a, and installed onto the guidance tool. It is carried by the belt 14 and processed by a processing tank group 12. After the processing, the paper 16 is cut by a cutting edge 23. The tip part 16a left in the guidance tool 5 is rotated half by an inserting arm 15c of the first member 24, and subsequently, the second member 25 contacts an end part 16d which becomes the front end by a half-rotation, said part is scraped from a groove 15d, and the tip part 16a of the paper 16 drops automatically from the guidance tool 15 and is removed.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to an automatic photographic developing device.

[Prior art]

In conventional automatic photo processing equipment, a leader fixture called a kanzashi is fixed to an endless belt that moves through multiple processing tanks, and photographic paper, which is a photosensitive material, is attached to this leader fixture. There is a device that supports and develops photographic paper as it moves with an endless belt, and the cost of the equipment is low;
It has advantages such as stable transportation.

However, such devices had the following drawbacks. That is, the conventional leading tool is as shown in FIGS. 1 to 3.
A base 3 having three hooks 2 that engage on both sides of the endless belt 1 has an elongated insert arm 5 protruding from the base 3, which has three hooks 2 that engage on both sides of the endless belt 1. As shown in <i7';5V, the tip 6 of the photographic paper 6 inserted
A is folded once, P is bent, and then wrapped again around L4 to prevent it from coming off. Furthermore, the leading tool supporting the photographic paper 6 in this way is manually attached to the locking pin endless belt 1. When the hook 2 is locked and the locking pin is released, it moves together with the endless bell 1 to convey the photographic paper.

After the development process, the leading tool is removed from the VC endless belt and the photographic paper is torn off by hand.
After cutting off all of the paper with a 0 tone cutter, the leading tool was removed from the endless belt and the remaining photographic paper was removed by hand.

[Purpose of the invention]

The present invention has been developed in view of the above-mentioned problems, and is designed to achieve full automation by automatically removing the processed photosensitive material from the leading tool.

[Structure of the invention]

Its features include a cutter that engages with the insertion arm of the leading tool to cut the transported material near the leading tool, and a cutter that comes into contact with the ntJ end of the proximal end of the cut photosensitive material. It has a first guide that inserts the tip and rotates it half a turn on the arm, and a second guide that comes into contact with the end of the half-rotated tip and scrapes the tip from the arm.

[Practice of the invention f/! 1] Hereinafter, one embodiment of the present invention will be described with reference to FIGS. An endless belt 14 suspended from the EI I, i: l rotates in and out of each part in the direction of the arrow.

A plurality of leading tools 15 are slidably secured to the endless belt 14. This lead tool 15 has hooks 15b formed at the four corners of a base 15a, and the base 15a and the hooks 15b.
The endless belt 14 is held between the belts 1 and 14.
4, an insertion yoke 150 is formed protruding from the base 15a, and a groove 15d is formed in the arm 15C.

An insertion opening 11a for photographic paper 16 is formed in the main machine frame 11 corresponding to the photosensitive material insertion section.
, a guide member 18 is provided, and when the leading tool 15 reaches the photosensitive material insertion part, a detection member 19 such as a micro switch that detects the leading tool 15 is activated to operate a -C stopper 20 to stop the leading tool from moving within the movement trajectory. An upper blade 22a1 and a lower blade 22b are provided to form a notch 16b) in which the insertion arm 15CVC can be fully locked at the tip 16a of the photographic paper 16 inserted into the groove 15d of the leading tool 15.
One incision forming member 22 is provided.

A mechanism for automatically removing the developed photographic paper 16 from the leading tool 15 is provided at an appropriate position behind the processing tank group 12. This mechanism includes a cutter 23 that cuts off the photographic paper 16 from the leading end 16a, and a cutter 23 that cuts off the photographic paper 16 from the leading end 16a, and a cutter 23 that abuts the front end of the leading end 16a of the photographic paper 16 remaining on the leading tool 15, and a cutter 23 that cuts off the photographic paper 16 from the leading end 16a.
The first guide 24 rotates half a lL] one time, and the first guide 24 rotates half a
Tip part 16a that is Cme f'l'l VilIi
I7) Touch the rear end and move the tip Milj part IGa to the leading tool 15
It has a stuffiness guide 25 that allows it to slide 7h from the insertion arm force.

Note that the first guide 24 is located at the tip 16a of the paper 16 marked 1I8ii.
It is provided at an angle in order to half-turn the first . The second guides 24, 25 are preferably made of a flexible material such as a leaf spring.

Next, the operation of the device configured in this way will be described. The leading tool 15, which is slidably engaged with the endless belt 14 moving in the direction of the arrow, moves together with the endless belt 14,
When the leading tool 15 reaches the vicinity of the photosensitive material insertion part, the detection member 19 detects the leading tool 15, and the solenoid 21 is actuated to project the stopper 20 into the moving trajectory of the leading tool, which temporarily stops at the photosensitive material insertion part and the endless belt. 14 continues to move.

Then, the photographic paper 16 is supplied by the supply roller 17, and its tip 16a is inserted into the groove 15d of the insertion arm 15C of the leading tool 15.
inserted into. And the upper blade 22 of the notch forming member 22
A and the lower blade 22b make a cut 16 in the tip 16a.
b is formed. When the upper blade 22a and the lower blade 22b are activated by V-coupling ω1 and the stopper 20 is retracted by the solenoid 21 and the connection with the guide tool 15 is released, the guide tool 1 is released.
5 moves together with the endless belt 14, and the photographic paper 14 is conveyed into the processing tank group 12 and subjected to development processing.

The developed photographic paper 16 is cut by the cutter 23 at a rearward position 501 of the insertion arm 15C of the leading tool 15 and taken out, as shown in FIG. 7(A). The front end 16a of the photographic paper 16 left behind on the insertion arm 15G of the leading tool 15 is brought into contact with the first guide 24 by the front end 16c as the endless belt 14 moves, as shown in FIG. 7(b). The insertion arm 1sc makes a half turn around the upper part of the groove, and as shown in FIG. 7(c), the second guide 25 makes a half turn and comes into contact with the front end 16d, scraping it off from the groove 15d. , the leading end 16a is automatically removed from the leading tool 15.

〔Effect of the invention〕

As described above, according to the present invention, the tip of the photosensitive material left behind on the leading tool can be automatically removed by turning the leading tool in half, making it easy to fully automatically transport the photosensitive material. becomes.
