Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a sheet film feeding device that conveys a sheet film between two devices, such as by connecting and operating a film conveying device to a photosensitive sheet film loading/recovering device.

Regarding equipment for processing sheet films such as X-ray films, for example, equipment for loading and recovering sheet films into cassettes is used in combination with other equipment depending on the conditions of installation and use.

FIG. 1 shows an example of its combined use.

In the figure, the inside of the receiver is kept light-tight, and the exposed cassette is opened to take out the film, transported to the receive magazine or automatic developing machine, and unused X-ray film taken out from the magazine is placed inside the cassette. , a receive supply device 1 which is inserted into the cassette and conveys the cassette to the outside of the device; a receive device 2 equipped with a receive magazine; an autofeed device 3 which takes out the film from the receive magazine 31 and conveys it to the automatic developing machine; A conveyor device 4 for conveying the film from a film processing device to an automatic developing machine is coupled to a merging conveyor device 5, and further an automatic developing device 6
It is combined with

In the figure, when the cassette 11 is inserted from the left side in the figure with its lid closed and conveyed to a predetermined position, a stop detector S11 is activated to stop the conveyance. Next, the opening/closing lid mechanism 12 is operated to open the cassette 11, and the built-in sheet film is taken out by the suction cup 13 and conveyed from the supply device 14 to the merging conveyor device 5.

The sheet film conveyed to the merging conveyor device 5 follows a conveyance path to the right or left by a preset selection section 51, and is conveyed to the automatic developing device 6 through a supply device 52. 53 and is conveyed to the receiving device 2. The sheet film conveyed to the automatic developing device 6 is developed and then discharged. Further, the sheet film conveyed to the receiving device 2 is stored in the magazine 21.

Further, the sheet film conveyed a distance by the conveyor device 4 is conveyed from the supply device 41 to the merging conveyor device 5, passes through the selection section 54, passes through the supply device 52, and is conveyed to the automatic developing device 6. Or through the supply device 53 to the receiving device 2
transported to. Also, from the magazine 31 loaded in the auto feed device 3, one feed is fed by a suction cup 32.
The sheet film is unloaded and conveyed from the supply device 33 to the merging conveyor device 5. The sheet film conveyed to the merging conveyor device 5 is conveyed to the automatic developing device 6 via the supply device 52.

In a combination device as shown in FIG. 1 which performs such unit coupling, for example, the receiving device 3
It may be necessary to remove each device such as the conveyor device 4 or the conveyor device 4. Each of these devices is made in the shape of a box, but if you do not close the transport port through which the sheet film installed on the wall of each device is transported when you remove them, light leakage may occur and an accident may occur. becomes. Conventionally, a worker had to operate a light-shielding plate to close the transport port. However, this was not only time-consuming, but also caused an accident if the user forgot to close it or forget to open it after installing it.

The purpose of the present invention is to eliminate the above-mentioned drawbacks, and the purpose is to create a light-tight interior between two devices that is equipped with a transport port for transporting the sheet film to another adjacent sheet film processing device. In the sheet film processing device held by the sheet film processing device, the device has means for detecting connection when connected to another sheet film processing device, and opens and closes the transport port in response to detection of the presence or absence of connection by the connection detection device. A member is provided on the wall surface of the processing apparatus on both sides of the transport port, and when connected to another sheet film processing apparatus, comes into contact with the other sheet film processing apparatus,
The present invention is achieved by a sheet film processing apparatus characterized in that a shielding member is provided to maintain light shielding between the processing apparatuses until the opening/closing member closes the transport port at least when the connection is released.

Hereinafter, the present invention will be explained in detail by way of examples and with reference to the drawings.

FIG. 2 is a sectional view showing the first embodiment of the present invention. Device A and device B, which have adjacent wall surfaces 71 and 72, respectively, are in a coupled state and have transport ports 73 and 74 at opposing positions. The wall surface 71 and the wall surface 72 are kept light-tight by a spigot 75.

The sheet film passes through transport ports 73 and 74 and is transported by transport rollers 76. The tip of a detection rod 78 urged leftward by a spring 77 protrudes from the wall surface 72 and comes into contact with the wall surface 71 .
The other end of the detection rod 78 is connected to one end of a link 79. The link 79 is designed to swing around a fixed support shaft 80, and a wire 81 is tied to the other end of the link 79, and the other end of the wire is connected to a shield biased downward by a spring 82. It is tied to the closing door 83.

When device A is to be removed from device B, the wall surface 71 moves away from the wall surface 72 and the detection rod 7
8 protrudes to the left, the link 79 rotates clockwise, lifts the blocking door 83 via the wire 81, and closes the conveyance port 74. This conveyance port 74 is closed by two walls 71, 7.
2 is performed while the light tightness is maintained by the spigot 75, so that no light leakage occurs when the device A is removed.

FIG. 3 shows a second embodiment, in which the detection rod 7
A micro switch 85 is provided at one end of the device B, and when the device A is to be removed from the device B, the micro switch 85 switches from ON to OFF and moves the blocking door 83 upward, either integrally or in conjunction with the blocking door 83. The solenoid 86, which had been operating to lift it up, is cut off, and the closing door 83 falls under its own weight, closing the transport port 74.
This conveyance port 74 is closed by two walls 71,
72 is carried out while the light tightness is maintained by the sponge 84 provided between them, so there is no possibility that light leakage will occur when the device A is removed. The second electrically implemented embodiment shown in FIG. 3 has the effect of further increasing safety by shutting off not only when the device A is removed, but also when the power is turned off.

The present invention described above not only saves the worker's time and effort, but also has the effect of increasing safety.
