Description

[Detailed description of the invention] Industrial application field This invention is an automatic processing device for photographic film that has already been photographed, in particular, a long reader that transports the film and applies processes such as development, fixing, washing, and drying. It relates to a processing device.

2. Description of the Related Art This type of processing device generally consists of a combination of a developing machine and a dryer, but for the purpose of saving installation floor space, a processing device is installed on the developing machine main body A as shown in FIGS. 5 and 6. In many cases, the dryers B are mounted and supported in a stacked state, and when using this stacking method,
Since the top surface of the developing machine main body A is blocked by the dryer B, for management convenience such as internal maintenance and inspection of the developing machine main body A, the dryer B is placed on one side of the lower part of the developing machine main body A. Assume that the edges are pivotally connected by a pivot member P, and by rotating the dryer B around the pivot member so as to lie forward or backward on its side as shown by the chain line in FIG. In many cases, the top surface can be left open.

Problems to be Solved by the Invention By the way, in the above-mentioned photographic film processing apparatus, the following problems have arisen, particularly when a long leader system is adopted as the film transport system.

That is, in the long leader conveyance method described above, the long leader 1 is passed through all processing steps in advance from each processing tank such as development and fixing in the developing machine main body A to the drying chamber 3 of the dryer B. When processing the film, the end of the film is connected to the rear end of the reader, and the film is indexed and transported by the reader. Therefore, the leader 1 is naturally guided continuously from the guide roller 4 on the exit side of the developing machine main body A toward the introduction guide roller 5 on the entrance side of the dryer B above it. Therefore, when the dryer B is rotated as described above to inspect the inside of the developing machine main body A with the leader 1 set in this way, the leader 1 is placed in the sixth position between the two. It will be forcibly pulled as shown by the chain line 1' in the figure. Therefore, in order to prevent the leader from breaking, the leader 1 is manually fed by a predetermined amount from the outlet side of the dryer B in the opposite direction to the normal feeding direction, so that the leader 1 is sufficiently spaced between the guide rollers 4 and 5. Dryer B could only be rotated after creating a sufficient margin. Of course, the above-mentioned feeding operation of the reader 1 is really troublesome and extremely inconvenient in terms of maintenance and management of the developing machine.

This invention aims to eliminate such inconvenience.

Means for Solving the Problems In order to achieve the above-mentioned purpose, this invention substantially fixes the final delivery guide roller on the developing machine side at a fixed position in the dryer, and provides a guide roller for introduction into the dryer. A vertical distance corresponding to the extra length of the leader required during rotation of the dryer is set between the leader and the roller.

That is, as shown in FIGS. 1 to 4 corresponding to the embodiment, this invention is a photographic film dryer B in which a dryer B is mounted and supported on a developing machine main body A so as to be rotatable backwards or forwards. In the automatic processing apparatus, a transfer rack 6 located at the outlet side end of the developing machine main body A is extended upwardly and protruded into the inlet side end of the dryer B. A feeding guide roller 1 provided at the upper end of 6
4, the introduction guide roller 15 in the dryer B to which the leader 1 or the film is guided via the roller 14 rotates about the pivot member P of the dryer B below the delivery guide roller 14. The gist of the present invention is an automatic processing device for photographic film, characterized in that the device is provided with a height difference h corresponding to a distance equal to or larger than the moving distance l of the introduction guide roller 15 at a time. It is.

Effect With the above configuration, when the dryer B is turned on its side with the pivot member P as the center as shown in FIG. It moves a distance l from P ₁ to P ₂ , but the introduction guide roller 1 is moved from the delivery guide roller 14 fixed to the developing machine main body A side.
5, the leader 1 is designed to have a height difference h between both rollers that can correspond to the above-mentioned distance l. Therefore, as shown in FIG. 4, the leader 1 allows the dryer B to rotate freely without causing any undue tension between the rollers 14 and 15 during the rotation of the dryer B.

Embodiment In Figures 1 to 3, A is the main body of the developing machine, B is the dryer mounted and supported on it, and P is a pivot member that allows the dryer B to be turned sideways to the rear. .

The leader 1 is guided from the entrance of the developing machine main body A around each processing zone therein into the dryer B, and is wound onto a take-up reel 7 from the exit end thereof. Reference numeral 8 designates an intermediate guide roller for guiding the leader 1 and the following film within the developing machine main body A, and 9 designates an intermediate guide roller of the dryer B as well.

A reader, etc. transfer rack 6 located at the exit side end of the developing machine main body A has both side frames 6a and 6b penetrating the upper wall of the developing machine main body A and the bottom wall of the dryer B and extending upwardly. and is thrust into the interior of the dryer B at the inlet side end. At the lower part of this transfer rack 6, intermediate guide rollers 8, 8 similar to those described above are provided at appropriate height positions within the developing machine main body A, while at the upper end protruding into the dryer, a flanged conveyor roller is provided. guide roller 14;
A restraining roller 16 for preventing the leader from coming off is attached close to the upper circumferential surface thereof. The feeding guide roller 14 is shaped like a medium-high drum, and the restraining roller 16 has a conical portion at its base.

On the other hand, an introduction guide roller 15 in the entrance side end of the dryer B through which the leader 1 or the film is guided via the delivery roller 14 is located below the delivery guide roller 14. Moreover, the height difference h between these rollers 15 and 16 is at least equal to or larger than the moving distance l of the introduction guide roller 15 when the dryer B is turned sideways around the pivot member P. ing. That is, h≧l is set. In addition, a small-diameter pinch roller 1 is provided on the lower side of the introducing guide roller 15 in contact with the lower circumferential surface thereof.
0 is set.

In the above, the leader 1 and the following films pass through the upper circumferential surface of the feed-out guide roller 14 to the lower side of the introduction guide roller 15 at the transfer point from the developing machine main body A side to the dryer B side. be guided. Therefore, we will now inspect the inside of the developing machine body A.
When the dryer B is turned on its side around the pivot member P for maintenance or the like as shown by the chain line in FIG. Leader 1 does not create tension as described above,
As shown in FIG. 4, it is in a "twisted" state and is in a state where it crosses between both rollers 14 and 15 with a margin. Moreover, even if this "twisting" occurs, the leader 1 is prevented from coming off the delivery roller 14 by the restraining roller 16, so after the above inspection, the dryer B is turned over to its original position. When it is returned, the reader 1 is automatically reset to its normal position.

Effects of the invention As mentioned above, this invention is an automatic processing device for photographic film that adopts the long leader method for film transport.Moreover, the dryer B is installed on the developing machine body A and can be rotated backwards or forwards. In an automatic processing device for photographic film mounted and supported, a transfer rack 6 located at the exit side end of the developing machine main body A is extended high upwards and plunged into the entrance side end of the dryer B. The feeding guide roller 1 provided at the upper end of the transfer rack 6
4, the introduction guide roller 15 in the dryer B to which the leader 1 or the film is guided via the roller 14 rotates about the pivot member P of the dryer B below the delivery guide roller 14. Since the guide rollers 15 are provided with a height difference h corresponding to a distance equal to or larger than the moving distance l of the introduction guide roller 15 at the time, maintenance inside the developing machine main body A can be avoided as described above. When rotating the dryer B for inspection, there is no need to perform the troublesome operation of feeding the leader 1 in the opposite direction from the outlet side of the dryer to give the leader some slack, as in the conventional method. It can be made into something. Therefore, while the reader is loaded, it is possible to freely knock down the dryer B and inspect the inside of the developing machine body A at any time.
Maintenance management and operational convenience can be further improved.
