Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a film transport device that transports photographed films of different sizes to an automatic developing machine.

[Prior Art] In such a film transport apparatus, for example, a photographed film is supplied and temporarily mounted on a film mounting table, and the film is sucked and taken out one by one from the film mounting table. Some are transported to an automatic developing machine via an automatic processor.

An example of the film mounting table will be described with reference to FIGS. A film front end abutment section 42 is provided below the back plate 41 of the film mounting table 40, and the lower end of the film F is placed in contact with the film front end abutment section 42. .

The film mounting table 40 is provided with a guide for referencing one side surface in the transport direction of the film F, that is, a one-side reference surface portion 43 in order to transport films F of different sizes. Along it, for example, a film F from six cuts to half cuts can be set.

The film width B differs in the transport direction (B1>B2> B
3) Each of the films F is placed on one side of the reference surface 43 so as to be offset, and the suction cup 44 for adsorbing the film F is connected to a compressor (not shown). And the film mounting table 40
And send it to the transport means.

[Problems to be Solved by the Invention] For this reason, for example, when a small film F is placed, if there is a suction cup 44 having no film F to be sucked,
The suction force is consumed by the suction cup 44, and the suction force of another suction cup 44 within the film width is weakened.

Therefore, the arrangement of the suction cups 44 had to be adjusted to the narrowest film width, for example, the film width B3 in FIG.

However, as shown in FIG. 6, a film F having a large width such as a film width B1, for example, a half-cut (17 inch wide) film F
As described above, since the arrangement of the suction cups 44 is biased toward the one-side reference surface 43 side as described above, the sucker 44 is sucked on the side opposite to the one-side reference plane 43 with respect to the portion (A) sucked by the suction cups 44. The portion (B) not adsorbed by 44 is in a state where the phase is delayed during the movement. In this state, when the suction of the suction cup 44 is released, a part of the film F does not fall freely to the next transport path because a part of the film F remains on the film mounting table 40. It was likely that the film F came into contact with the front end butting unit 42 and dropped obliquely, resulting in poor conveyance.

Also, in order to eliminate the above-mentioned conveyance failure without changing the position at which the suction cup 44 releases the suction shown in FIG. 6, that is, the home position (I), the sixth phase is moved by the amount corresponding to the phase delay during the movement. In the figure, it is necessary to retract the film mounting table 40 by the distance L0, which has a disadvantage that the film transport device becomes large.

The present invention solves the above-mentioned drawbacks of the conventional film transport apparatus, can easily transport the film to the outside of the film mounting table, and reliably transports films of different sizes without increasing the size of the apparatus. It is an object of the present invention to provide a film transport device capable of performing the above.

[Means for Solving the Problems] In order to solve the above problems, a film transport device according to the present invention includes a back plate portion of a film mounting table on which films of different sizes can be mounted, and one side surface in the film transport direction. A one-side reference surface provided on one side of the back plate for placing the same, and a one-side reference surface of a film provided and mounted on the back plate opposite to the one-side reference surface. A projecting portion for projecting the opposite end from the end toward the discharge side, a film tip abutment portion provided so that the lower tip of the film abuts on the lower back portion, and a bias toward the one-side reference surface portion side. And a film suction moving means which is disposed opposite to the back plate portion and moves the film out of the film mounting table while moving toward and away from the film.

[Operation] In the film transporting apparatus of the present invention, films of different sizes are placed on the back plate of the film mounting table along one side of the reference surface with one side in the transport direction of the film aligned. The back plate is provided with a protruding portion on the side opposite to the one-side reference surface portion. The protruding portion protrudes from the end on the one-side reference surface portion side of the film to the discharge side. This film is successively sucked by the film sucking and moving means disposed opposite to the film mounting table, and the film is carried out to the film front end abutment section.

At this time, the film, from its one reference surface side end,
Since the opposite end protrudes toward the discharge side, it is reduced that a portion that is not adsorbed on the opposite side of the one-side reference surface portion has a phase delay when moving. For this reason, a part of the film does not remain on the film leading end abutment portion, and the film can freely fall to the next transport path. In addition, a part of the film comes into contact with the film front end abutment portion, and the film does not drop obliquely, so that a conveyance failure or the like does not occur.

Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a side view showing the overall structure of the film transport device of the present invention, FIG. 2 is a perspective view of a film mounting table, FIG. 3 is a plan view of the film mounting table, and FIG. It is a figure which shows the state which carries out.

In FIG. 1, a film transport device 1 is mounted on a gantry 2 and transports a photographed film F to an automatic developing machine (not shown). A film supply unit 3 is provided at an upper portion of the film transport device 1, and the film F is supplied from the film supply unit 3 into the mounting. As shown in FIG. 2, the size of the supplied film F can be, for example, each size from six cuts to half cuts, and these films F are provided at the lower part of the film supply unit 3. It is mounted on the mounting table 4. The film mounting table 4 has a back plate 5 inclined at a predetermined angle with respect to the vertical direction, and each film F is mounted on the back plate 5. In order to transport films F of different sizes to the film mounting table 4, a guide for referencing one side surface in the transport direction of the film F, that is, a one-side reference surface portion 6 is provided on one side surface portion of the back plate portion 5. Films F of different sizes are set along the one-side reference surface portion 6.

A projecting portion 5a is provided on the back plate portion 5 opposite to the one-side reference surface portion 6, and a film F having a wide size is placed across the back plate portion 5 and the projecting portion 5a. In this mounting state, the film F mounted on the back plate portion 5 at the protruding portion 5a has an end F2 on the opposite side from the end F1 on one reference surface side protruding toward the discharge side. As shown in FIG. 1, a guide 3a is provided above the protruding portion 5a, and the film F is guided by the guide 3a, so that the film F is easily loaded onto the protruding portion 5a. Further, as shown in FIGS. 2 to 4, the protruding portion 5a is inclined from the outer portion 5b to the inner portion 5c so that the end of the film F projects toward the discharge side.

The protruding portion 5a may be formed separately from and fixed to the back plate portion 5, may be formed integrally with the back plate portion 5, and the shape of the protruding portion 5a is not particularly limited.

Further, a film front end abutment section 7 having a cutout portion 7a at the end opposite to the one-side reference surface section 6 is provided at a lower portion of the film mounting table 4, and the lower end of the film F has a film front end. It comes into contact with the abutment portion 7. Further, a film separating means 8 having a convex cross-sectional shape is provided on the film leading end abutment portion 7 similarly to the one-side reference surface portion 6 side.

A film sucking / moving means A is disposed so as to be deviated to one reference surface 6 side of the film mounting table 4 and opposed to the back plate 5, and the film sucking / moving means A moves toward and away from the film F. Then, the film F is carried out of the film mounting table A.

Since the film F set on the film mounting table 4 is in close contact with each other and so-called blocking is likely to occur, the film suction moving means A is used to separate and transport the film F one by one. And two suction cups 9 facing each other, and the suction cups 9 are arranged so as to be displaced toward the one-side reference surface portion 6 side.

In order to increase the frictional resistance, the film separating means 8 may be formed with a corrugated narrow groove on its surface, or may be coated with a rubber film on its surface.

Next, the operation of separating and unloading the film F will be described in detail with reference to FIGS.

As described above, the films F having different film widths B in the transport direction (B1>B2> B3) are mounted on the film mounting table 4 while being shifted to the one-side reference surface 6. The suction cup 9 disposed opposite to the film F is initially located at the home position (I). The suction cup 9 is connected via a conduit 10 to a compressor (not shown), and sucks the film F by driving the compressor.

In addition, the suction cups 9 are arranged in accordance with the narrowest film width, that is, the film width B3, so that the plane arrangement of the suction cups 9 is not open air. The number of the suction cups 9 is, of course, not limited as long as the suction cups 9 are arranged within the above-mentioned range of the film width and as long as the film F can be held by suction.

The sucker 9 and the conduit 10 can be moved toward and away from the film F by the driving means 11, and after the film F is supplied to the film mounting table 4, the driving means 11 is driven. The suction cup 9 is brought into contact with the film F to be sucked.

Thereafter, as shown in FIG. 4, the sucked film F is moved toward the home position (I) while being sucked and held by the sucker 9. By this movement, the film F moves while sliding on the film leading end abutment portion 7, and slides the lower end of the film F attracted to the film separating means 8, so that the film F is separated one by one by its frictional resistance. Then, it is moved to the position of the home position (I).

At this time, when the film width of the film F to be sucked is B3, B2, the film F is mounted on the film mounting table 4 so as not to interfere with the protrusion 5a. When the film width of the film F to be sucked is B3, the movement phase is not delayed in the portion not sucked by the suction cup 9, and the film F
Even when the film width is B2, the movement phase is relatively little delayed in the portion not sucked by the suction cup 9.

At this time, if the film width of the film F to be sucked is large, such as B1, the film F is placed across the back plate portion 5 and the protruding portion 5a. The portion not adsorbed by 9 is located on the discharge side on the home position (I) side, whereby the delay of the movement phase is corrected. Furthermore, the presence of the protruding portion 5a causes an air reservoir K to be formed between the film F and the back plate portion 5, so that the film F can be prevented from sticking to the back plate portion 5, and smooth suction can be performed.

By the way, when the film width of the film F to be sucked is as large as B1, the one-side reference surface portion 6 of the film F
Even if a phase lag of the temporary movement occurs in a portion which is not sucked by the suction cup 9 on the opposite side of the film, the film leading end abutment portion 7
In the home position (I) where the suction cup 9 releases the suction, the entire area of the sucked film F is located outside the film leading end abutment 7 because of the notch 7a.

When the suction cup 9 releases the suction at the home position (I), the film F separated one by one as shown in FIG. In some cases, the phase may be delayed by the distance L0, and even if suction is released in this state, the film leading end abutment 7 has a cutout portion 7a on the opposite side of the one-side reference surface portion 6. Therefore, a part of the film F does not remain on the film leading end butting portion 7,
It can fall freely to the next transport path. Also,
A part of the film F comes into contact with the film front end abutment portion 7, and the film F does not drop obliquely, so that a transport failure or the like does not occur.

In this way, the film F falls freely into the drop guide 12, and is then guided by the transport rollers 13 and the transport guide 14,
It is carried out to an automatic developing machine (not shown).

Note that the planar shape of the cutout portion 7a of the film leading end abutment portion 7 may be appropriately determined according to the position of the home position (I) of the suction cup 9, the stroke of the suction cup 9, the film size, the curl state of the film, and the like. .

[Effects of the Invention] As described above, in the film transporting device of the present invention, since the projecting portion is provided on the back plate portion of the film mounting table on the side opposite to the one-side reference surface portion, the projecting portion provides one-side reference surface portion of the film. The opposite end protrudes from the side end to the discharge side. For this reason, when the film is sucked by the suction moving means and is carried out of the film front end abutment portion,
The opposite end of the film protrudes to the discharge side from the one reference surface side end, so that the portion that is not adsorbed on the opposite side of the one reference surface portion does not have a phase delay when moving. Therefore, a part of the film does not remain on the abutment portion of the film and can freely fall to the next transport path, and a part of the film contacts the abutment portion of the film. The film can be easily transported out of the film mounting table without causing the film to drop obliquely or causing transport failure, etc., and multiple films of different sizes can be secured without increasing the size of the mounting device. Can be transported.
