Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement of a photographed sheet film recovery device for a 5xtji photographic device, and the present invention relates to an improvement of a photographed sheet film recovery device for a 5xtji photographic device. Even if film is used, the film can be collected and collected smoothly in the collection magazine.
The present invention provides a photographic film recovery device for a radiography device.

Conventionally, a single size cassetteless sheet film was used.
In an X-ray imaging device, the sheet films that have undergone X-ray imaging are sequentially ejected from the imaging area, and fed into the collection magazine diagonally from the top side of the collection magazine using a feeding roller, and then stored in a stack. Photographic film recovery devices designed to do this are known.

In such a single-size film recovery device, the size of the recovery magazine is almost the same as the size of the sheet film, and the feed roller is installed as close as possible to the top surface of the recovery magazine at one end thereof. Then, the direction in which the film enters the collection magazine becomes relatively parallel to the film accumulation surface of the collection magazine, and the film can be easily slid into the collection magazine. When it reaches the other end, the rear end of the film comes off the feeding roller and falls into the collection magazine, so the leading edge of the film easily hits the wall of the collection magazine and is aligned. They will be stored in a stacked state. However, if the photographed film has self-staining characteristics, it may not be fed into the collection magazine from the feed roller.

In addition, when using sheet film of a size suitable for X-ray imaging equipment, especially when the lengths in the feeding direction to the collection magazine are different, it is necessary to place the leading edge of the film on the wall of the collection magazine as described above. It is no longer possible to stack and store them in a state where they are aligned against each other. In other words, since the collection magazine must be able to store the largest size of sheet film, if there are lengths in the feeding direction of the sheet film to the collection magazine, then for that long film, Even if you can store the film with the ends aligned like before, for short films, by the time the end of the film reaches the wall of the collection magazine, one end will get caught in the feed and come off the roller, falling into the collection magazine and falling from the center of the film. It is not possible to stack and store all films of different sizes with their tips aligned with the wall of the collection magazine. x! I When photographic film is taken out of the photographic koji equipment and placed in an automatic developing device, and the photographic film is developed one after another by the automatic developing device, the film cannot be taken out smoothly from the collection magazine, making it impossible to develop it. This causes such inconvenience.

The present invention was developed in order to eliminate the same layer as described above.The sheet film that has been photographed is sequentially dyed into the collection magazine from the top side using the feeding and dyeing roller. A photographic film collecting device for an X-ray photographing apparatus that is stacked and stored, wherein an air blowing nozzle and a guide are arranged between the paper feeding roller and the collecting magazine, and the air blown from the nozzle causes the sheet film to follow the guide. A photographic film collection device for an l-ray photographic apparatus is characterized in that the photographic film collection device for an l-ray photographing apparatus is provided with one device for blowing the film into a collection magazine along with the film.

The present invention will be explained below based on illustrated examples.

FIG. 1 is a schematic sectional view showing an example of an X-ray imaging apparatus according to the present invention, FIG. 2 is a sectional view of a portion of a photographic film recovery device, and FIG. 3 is a partial plan view of FIG. 2.

In FIG. 1, cassetteless sheet films of different sizes are each fed into a feeding magazine F/.

] It is taken out from r by suction supply devices 8/, S, is supplied to paper feed rolls R/, R, is guided by paper feed guides G/, G, and reaches intermediate feed roller Rj.
Furthermore, feed roller R4! , the sand feeding guide G3 and the sand feeding rollers RjK are fed into the photographing area. and,
The photographic film 1, which has been photographed at 1g indicated by the arrow in the photographing area E, is sent to the feed roller of the recovery device by the discharge roller R4 and the G roller.

In FIGS. 2 and 3, l denotes a photographic film including different sizes photographed in photographing area X, and C denotes a feeding roller, which are the same as those in No. 1 IIK. It is assumed that the photographic film l has different lengths in the feeding direction of the feeding roller. However, the dimensions of the film I in the width direction of the L1 feeding roller may be the same or different.

The feed roller 9 transports the film 1 into the collection magazine set inside the collection frame 3 of the X-ray imaging device.
4Lb, which is inserted diagonally from the opening loader a on the upper surface side, is a sliding door for the collection magazine, which blocks the opening loader a from light. As shown in the first WJ, it is preferable that the collection magazine is loaded into the frame of the collection unit in an inclined state in which the advancing direction of the film 1 being fed is downward. Then, as in the conventional collecting device, when the rear end of the film l comes off the feeding roller, it falls into the collection magazine Hironai without any trouble.
It is provided at one end of the collection magazine l.

For such a feed rollercoat and a collection magazine 30,
An air blowing nozzle and a feeding guide t are each fixedly provided on the collection section frame 3. In addition, 7 and l are a ventilation fan and a ventilation duct, respectively.

The air blown from the nozzle j, indicated by the arrow, blows the film l sent in by the rollercoat along the guide ≦, and further blows it into the collection magazine along the film l. For this purpose, the angle θ between the feeding direction of the film I by the feed dye roller and the feed dye guide t and the film stacking bottom surface of the collection magazine is tzs.
The angle θ is preferably in the range of '~/41''.
When becomes smaller than /Jj', the air blowing from nozzle 5 causes a blowing effect! When the size becomes larger than 0, there is no longer enough space to install the nozzle 5, etc.

As described above, the air blown from the nozzle j causes the film l to follow the guide ≦ positioned on the upper surface of the film l, so that the film l can be reliably placed in the collection magazine even if it has some bends or irregularities. Also, the blown air flows along the film I into the collecting magazine l.
By being blown in, the film L is easily blown away within one collection magazine L, and the stacked storage of films with the leading edge aligned with the wall surface of the collection magazine L becomes K.

As mentioned above, if the length of the film in the feeding direction has a length, the extension of the guide t in the film guiding direction will be larger than the wall of the collecting magazine in the film advancing direction. The shortest length of the film L from the PC to the front! It should be located closer to the wall surface PC than the far position. As a result, even if another film L is fed into the collection magazine after a short length of film L, the leading edge of the film L will not get caught on the rear end of the short length of film L that was fed first. This does not happen, and all sizes of films can be stacked and stored with their tips touching the wall of the collection magazine.

1*, the illustrated collection device includes a static eliminator 9 that removes the static charge from the film L, and a rear end of the film L that is caught in the upper entrance of the wall of the collection magazine L on the opposite side of the film traveling direction. In such a case, a pushing plate 10 for pushing the film l into the collection magazine l is provided on the side of the feeding guide 6. This pushing plate 10 is connected to the collecting section frame 3.
A rack is provided on the movable guide // which is movable along the top surface, and when the movable guide // is moved in the direction of the arrow, the pushing plate wheel /3 is moved counterclockwise via the pinion lλ that engages with the rack. When rotating in the direction, from K,
Together with this, it rotates counterclockwise to push the film into the collection magazine l. Such a pushing device can be operated automatically by providing a detection means such as a photoelectric or limit switch above the entrance of the collection magazine where the rear end of the film l is caught. be able to.

The static eliminator may be provided before the feed roller or may be provided along with the pushing device if necessary, but it is very difficult to store the film stably. It is valid.

As described above, according to the present invention, even in a single size film, the influence of songs and quirks can be corrected.

KL enables smooth stacked storage in the collection magazine.Especially in X-ray imaging systems that use films with different lengths in the feeding direction, stacked storage with the leading edges of the films aligned, which was not possible with conventional collection devices, is possible. enable.
