The film 14 falling is such a condition has its curl corrected by abutting on a pillow member 146 and becomes to be supported in the curved (protruded downwards) condition in the width direction. When there is only one sheet of film 14, its central part in the width direction of the film 14 in such a supported state is not in contact with the bottom 142A of the box, or in other words, it is supported by being hung across a pair of pillow members 146. Thus successive films 14 falling one after another are accumulated as having their curls corrected correspondingly to the above therefore hindrance for accomulation of the film 14 falling next by virtue of its curl can be prevented.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a film accumulating box for accumulating films that are naturally curled in a curled state that is convex downward.

[0002]

2. Description of the Related Art Conventionally, in a processing apparatus for recording an image on a sheet-like film such as microfiche and developing it,
The film wound into a roll is pulled out, positioned at the exposure position, cut to a predetermined length after exposure, and conveyed to the development processing step.

In the development processing step, the film is conveyed while being immersed in the processing solution, developed, fixed and washed with water, and the film treated with the processing solution is dried by a drying air. The dried film is discharged from the apparatus main body and accumulated in a predetermined vat (saucepan).

[0004]

However, in a film processing apparatus having a conventional structure, when a film having a strong curl is accumulated when the film is accumulated, the curl may be crushed to bend the film, and It may not be integrated on the previous film.

In particular, when the curl is convex downward and is accumulated (when the photosensitive surface is upward, a curl convex downward is generated), the above-mentioned problem is apt to occur and the defective accumulation occurs. I was waking up.

In view of the above facts, an object of the present invention is to obtain a film stacking box capable of surely stacking a curled film.

[0007]

According to a first aspect of the present invention, there is provided a film accumulation box for accumulating a film that is naturally convex in a downwardly curled state, and is orthogonal to the direction in which the curl occurs. By raising the bottom portion corresponding to the both end portions of the film, the spontaneously falling film is hung over the raised portion, and the center of the both end portions of at least the first film is in the direction orthogonal to the curl. It is characterized in that it is curved and is not in contact with the bottom portion.

[0008]

According to the first aspect of the invention, for example, when the first film is curled in a state where the film is curled along the transport direction and the downward curl is generated in the stacking box. When naturally falling, the intermediate portion in the film transport direction first comes into contact with the raised portion. After that, due to the weight of the film,
When the center of the film (in the vicinity of the intersection of the diagonal lines) is lowered, the center in the film width direction is lowered in a state in which both ends of the film width direction (both ends orthogonal to the curl direction) are supported by the raised portion. As a result, the curl is corrected, and the curl is curved in a so-called toyo shape having a relatively small and substantially constant curvature. In this case, due to the waist of the film, the central portion in the width direction is in a state of not being in contact with the bottom of the stacking box, that is, a state of being stretched over the raised portion.

In this toyo-shaped curved state, the film is conveyed in a straight line and only the toyo-shaped curve having a small curvature in the width direction is formed. Curved.

That is, in order to correct the curl that changes depending on the processing condition, an extremely small curl (toyo shape) is formed in a direction orthogonal to the curl direction, so that the curl is surely collected regardless of the strength of the original curl. Done.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows a film processing apparatus 10 according to this embodiment. The film processing apparatus 10 is loaded with a supply roll magazine 12, and the roll-shaped film 14 stored in the supply roll magazine 12 is pulled out and processed.

The drawn film 14 is first positioned at the exposure position of the exposure device 16, the image is exposed, and then cut into a predetermined length by the cutter 18 and sent to the development processing section 20. The exposure device 16 is adapted to expose the main image together with the title characters and symbols for identifying the film 14. In the present embodiment, the standard film 14 has a size of about 148 mm in the transport direction and about 105 mm in the width direction. The wall thickness is 100 μm.

A stocker section 22 is provided on the right side surface of the development processing section 20 so that the films 14 processed by the development processing section 20 are accumulated.
The stocker unit 22 will be described later.

In the casing 24 of the development processing section 20, a processing solution processing section 26, a squeeze section 28 and a drying section 30 are provided. The processing liquid processing section 26 includes two developing processing sections 26A, 2A,
6B, two fixing processing parts 26C, 26D and three water washing processing parts 26E, 26F, 26G.

Each of these processing units is provided with a box-shaped rack 32. The racks 32 are supplied with respective processing liquids, and are driven by a motor (not shown) to horizontally convey the film 14 with a pair of rollers 34. There are two pairs each.

The processing liquid in the rack 32 is circulated and used, and is heated at the time of circulation to be maintained at a temperature within a predetermined range.

Therefore, the film 14 fed into the processing liquid processing section 26 is conveyed horizontally while being developed.
6A and 26B development processing and fixing processing units 26C and 26D
The fixing process and the washing process in the washing process parts 26E, 26F and 26G are performed.

A squeeze portion 28 is provided on the downstream side of the water washing processing portions 26E, 26F and 26G. A squeeze roller 36 is provided in the squeeze portion 28.
The squeeze roller 36 is configured to squeeze the film 14 sent from the rinsing processing unit 26G and to which the rinsing water is attached, and to convey it to the drying unit 30 in the next step.

In the drying section 30, a pair of transport rollers 38 for transporting the film 14 are arranged vertically at a plurality of locations. The transport roller pair 38 is rotated by the driving force of a driving unit (not shown), and transports the film 14 fed into the drying unit 30 in the horizontal right direction. The drying unit 30
A heater 40 and a fan 42 are provided, and the fan 42 blows dry air onto the surface of the film 14.

The film 14 that has been dried in the drying section 30 is nipped and conveyed by two pairs of exit rollers 44 and reaches the stocker section 22.

By the way, the photosensitive surface of the film 14 discharged from the pair of exit rollers 44 faces downward, and in this state, the image exposed by the exposure device 16 is viewed in a normal state (when viewed from above. ), The opposite image. Therefore, the title characters, symbols, etc. for identifying the film 14 exposed with the main image also become reverse images. For this reason,
In the stocker section 22, the film 14 discharged from the exit roller pair 44 is reversed.

The stocker section 22 is housed in a frame casing 100 assembled in a frame shape, and is arranged along the conveying path of the film 14 discharged from the pair of exit rollers 44, and the film is inverted. And a stacking unit 104 that is arranged below the stacking mechanism unit 102 and stacks the reversed film 14.

(Reversing Mechanism Section 102) As shown in FIGS. 2 and 3, the film 1 discharged from the exit roller pair 44.
4 is mounted on a swing bat 106 as a support. The swing bat 106 has a box shape and an inclined surface is formed on the bottom surface at an intermediate portion in the film transport direction.
A step is formed in which the downstream side is lower than the upstream side. A pair of claws 108 are formed at the upstream end of the swing bat 106 in the film transport direction, and the base of the claw 108 is placed on the swing bat 106.
4 corresponds to one end of the outlet roller 4 and the leading end of the outlet roller pair 44.
It is close to the peripheral surface of the lower roller 44A.

Here, the film 14 is curled due to the difference in expansion and contraction of the base layer and the photosensitive layer of the film 14, and since it is wound into the roll, the curl due to the curl is caused. It has occurred. Since these curl directions are convex upward in the horizontal transport state, the film 14 discharged by the exit roller pair 44 is discharged in the curl state. For this reason, it may be caught up following the rotation of the lower roller 44A of the outlet roller pair 44. The claw portion 108 has a function of peeling the film 14 in which the winding has occurred from the lower roller 44A and reliably guiding the film 14 to the swing bat 106.

A stop plate 110 is mounted on the lower surface of the swing butt 106 so as to be slidable in the film transport direction. The position of the stopper plate 110 can be changed according to the length of the film 14, and the swing bat 1
The position of the film 14 on 06 is fixed and a predetermined curled state is formed. For example, if the length of the film 14 is 148 mm, the swing bat 10
The length of the substantial supporting surface on 6 is preferably 130 mm.

On the bottom surface of the swing bat 106,
Three guide shafts 112 as ribs are arranged parallel to the film transport direction. This guide shaft 1
The strips 12 are arranged along the bottom surface of the swing bat 106 in a streak shape and directly support the leading end of the film 14 in the transport direction. The leading edge of the film 14 may abut in a nearly vertical state due to curl. By supporting the leading end of the film 14 on the guide shaft 112, it is possible to prevent the film 14 from being caught and smoothly guide and convey the film.

The swing butt 106 is supported by the swing arm 114. This swing arm 114
Are assembled in a rectangular frame shape by a pair of arm members 116 that are parallel to each other and a pair of stays 118 that are hung on the arm members 116. A cylindrical spacer 120 is laid between the arm members 116 near the downstream end in the film transport direction. This spacer 12
A circular hole (not shown) is formed at a position of the arm member 116 which is coaxial with 0, and the shaft 122 penetrates the hole.

The shaft 122 is pivotally supported by the frame casing 100, whereby the swing arm 114 is rotatable about the shaft 122.

A spur gear 124 is attached to the outside of one arm member 116 of the shaft 122.
Further, the frame casing 100 is provided with a drive unit 130 including a motor 126 and a speed reducer 128. Output shaft of this drive unit 130 (not shown)
A spur gear 132 is attached to and meshes with the spur gear 124. The drive of the motor 126 is controlled by a signal from the control unit 134. When the motor 126 is driven, the friction 113 and the swing arm 114 are driven.
(And the swing bat 106) is adapted to rotate from a substantially horizontal position to a substantially vertical position. By this rotation, the film 14 on the swing bat 106 is reversed with its front and back sides dropped. That is, since one end of the film 14 is supported by the claw portion 108 up to the substantially vertical position of the swing bat 106, the film 14 is rotated together with the swing bat 106 (approximately 1).
10 °), when it reaches a substantially vertical position, only the film 14 is rotated and inverted due to the displacement of the center of gravity (the displacement from the state where the center of gravity is in the direction approaching the swing bat 106 to the state where it is separated). .

When the film 14 is placed on a flat surface, the center of gravity of the film 14 and the swing bat 10 are displaced.
Although the rotation position of 6 depends on the strength of the curl, in this embodiment, since the step is provided on the bottom surface of the swing bat 106, even if the center of gravity is displaced during the rotation of the swing bat 106 or the swing bat 106 is in a substantially vertical position. It eliminates the instability that the center of gravity is not displaced.

The substantially horizontal position and the substantially vertical position are detected by position detecting sensors 136 and 138, respectively. These position detecting sensors 136 and 13 are detected.
The signal line 8 is connected to the control unit 134. A signal line from a film detection sensor 140 arranged near the exit roller pair 44 is also connected to the control unit 134, detects the rear end of the film 14, and the film 14 is supported on the swing butt 106. You can recognize that.

(Stacking Unit 104) FIG. 4 shows a stacking box 142 for receiving and stacking the film 14 which has been inverted and dropped.
Are shown in detail.

The accumulating box 142 corresponds to the width direction both ends of the film 14 and one end in the transport direction from the bottom 142A.
A plurality of side wall portions 142B, 142C, 142D are provided upright, and a guide rod 144 is provided upright from the bottom portion on the side portion near the apparatus body. Such a stacking box 142 on the desk is detachably arranged at the bottom of the frame casing 100. The surface area of the bottom portion 142A is equal to that of the film 14 to be integrated.
Is slightly larger than the area.

Pillow members 146 are arranged in the bottom portion 142A at positions corresponding to both ends of the film 14 in the width direction along the transport direction. The pillow member has a substantially triangular contour in the circumferential direction and a corner shape, and is an inclined surface that becomes lower as the supporting surface of the film 14 approaches the center. As shown in FIG. 5, the widthwise inner dimension X of the stacking box 142 is 11
If it is 5 mm, the maximum height H of the pillow member 146 is 10 m.
The width m is 20 mm and the width W is 20 mm.

Here, the reversed film 14 falls downward in a curled state that is convex along the transport direction. By contacting the pillow member 146, the film 14 falling in such a state has its curl corrected and is supported in a state of being curved (projected downward) in the width direction. In this support state, the first film 14 is in a state in which the widthwise central portion is not in contact with the bottom portion 142A, that is,
The pair of pillow members 146 are supported while being suspended.

Therefore, the films 14 that are successively dropped are also accumulated while curling is corrected in accordance with this.
The curl prevents the film 14 that falls next from being accumulated.

At the center of the frame casing 100, on which the stacking box 142 is mounted, the guide plates 14 are provided in correspondence with both end portions in the film width direction and the end portion on the film apparatus main body side.
8A to 8C are attached, and a guide portion 150A is formed on the cover member 150 that covers the frame casing 100 corresponding to the remaining one end portion. These guide plates 1
48A to C and the guide portion 150A are inclined in a direction in which they gradually approach each other as they go downward, and guide the falling film 14 toward the stacking box 142.

Below the frame casing 100, one end of each of a pair of arms 152 is pivotally supported. These arms 152 are extended to the lower end of the stacking box 142 on the outlet side, and a stopper member 154 having a substantially triangular shape is bridged. One end of a tension coil spring 156 is locked to the stopper member 154, and the other end is locked above the frame casing 100. Therefore, the stopper member 154 has the extension coil spring 1
Normally, the stacking box 142 is positioned on the attachment / detachment movement trajectory by the urging force of the stacking box 142. When the stacking box 142 is mounted, the inclined surface of the stopper member 154 abuts on the corner of the stacking box 142, and It is adapted to be pushed down against the biasing force of the coil spring 156. Further, when the stacking box 142 is completely mounted, it is pulled up again by the urging force of the tension coil spring 156 to prevent the stacking box 142 from coming off.

When taking out the stacking box 142, the stopper member 154 may be pressed.

Below the frame casing 100, a contact plate 158 is arranged corresponding to the guide bar of the stacking box 142. The contact plate 158 is formed with a slit-shaped notch portion 158A for preventing interference with the guide rod 144, and can enter the inside of the accumulation box 142 in a slightly mounted state. The lower part of the contact plate 158 is urged by the compression coil spring 160, and presses the film 14 to be accumulated to the other side wall portion 142B, so that the film 1
4 is separated from the guide rod 144.

The operation of this embodiment will be described below. The roll-shaped film 14 is pulled out, positioned at the exposure position of the exposure device 16, and the image is exposed. In this case, the exposure surface faces downward, and the title characters and symbols are exposed together with the main image. When the exposure is completed, it is cut into a predetermined length and conveyed to the development processing section 20. In the development processing unit 20, while being conveyed horizontally, development processing is performed while being immersed in the processing liquid (developing liquid, fixing liquid, washing water) in the processing liquid processing unit 26, and then adhered by the squeeze roller 36 in the squeeze unit 28. The washed water is squeezed and conveyed to the drying unit 30. In the drying unit 30, a drying air is blown onto the surface of the film 14 to dry it. The film 14 that has been subjected to the drying processing in the drying unit 30 has two pairs of exit rollers 44.
It is nipped and conveyed to the stocker section 22. The film 14 discharged from the pair of exit rollers 44 is curled upward. This is caused by a curl when wound in a roll shape and a difference in expansion and contraction between the exposed surface and the base surface due to development processing, drying processing, etc., and in particular, curl strength is weak between the roll-shaped unwinding and the core. It's very different. Further, the strength and weakness of the curl also changes depending on the time during which the curl is rolled up.

In the stocker section 22, the position detection sensor 1
The swing bat 106 stands by in a horizontal state by the control of the control unit 134 by the detection of the film 36.
Are gradually fed onto the swing bat 106.

Here, the claw portion 10 is attached to the swing bat 106.
8 is formed in a protruding shape, and the tip end thereof is brought into sliding contact with the lower roller 44A of the outlet roller pair 44, so that the film 14 is curled, and even if it is fed so as to be wound around the lower roller 44A. The film 14 can be reliably guided to the swing bat 106 by the claw portion 108.

Further, at the bottom of the swing bat 106,
Since the three guide shafts 112 are provided, the film 14 slides well, and even if the curl is strong and the tip portion is in contact in a substantially vertical state, the film 14 can be surely slid.

When the film detection sensor 140 detects the rear end of the film 14, after a predetermined time has elapsed (after the time from the position of the film detection sensor 140 until the rear end of the film reaches the swing butt 106), the control unit. 1
A driving signal is output from the motor 34 to the motor 126, and the motor 1
The driving of 26 is started.

By driving the motor 126, the spur gear 1
The swing arm 114 rotates via 24, 132,
At the same time, the swing bat 106 starts rotating.

The swing bat 106 moves (rotates) from a substantially horizontal position to a substantially vertical position in about 2 seconds. If the moving time is too fast, the film 14 is not stable, and if the moving time is too slow, the timing with the development processing section does not match, so that 1 second or more,
It is optimal to set it to about 2 seconds. In addition,
The substantially vertical position is detected by the position detection sensor 138,
The drive signal from the control unit 134 to the motor 126 is stopped, and the swing bat 106 is stopped.

By the rotation of the swing bat 106,
One end of the film 14 is supported by the base of the claw 108 and is rotated by about 110 °.

If the support surface of the film 14 (the bottom of the swing bat 106) is a flat surface, the displacement of the center of gravity becomes unstable due to the curled state of the film, and the film 14 swings while the swing bat 106 rotates. It may start to separate from 106. However, in this embodiment, since the step portion is provided at the bottom of the swing bat 106, the displacement of the center of gravity becomes slow, and the displacement of the center of gravity occurs when the swing bat 106 reaches the substantially vertical position regardless of the curled state, The support portion for the claw portion 108 serves as a center to separate from the swing bat 106.

The film 14 separated from the swing bat 106 has a thickness of about 1 with the supporting part for the claw 108 as the center.
Rotate 10 °, which completes the inversion.

The inverted and curled film 14 is naturally dropped as it is, guided by the guide plates 148A to 148C and the guide portion 150A, and reaches the stacking box 142.

In the accumulation box 142, the pillow member 14 is provided on the bottom of the accumulation box 142.
6 is provided, the film 14 is used for the pillow member 1.
46 is abutted. Since the pillow member 146 is formed with an inclined surface which is gradually lowered toward the center of the stacking box 142, the film 14 is curved along the inclined surface,
The curl is corrected and supported in a so-called toyo shape. In this case, the central portion in the width direction of the first film 14 is the accumulation box 1
It is supported in a state of being hung over a pair of pillow members 146 without contacting the bottom of 42.

Usually, the curl is weak when the vicinity of the outside of the film 14 wound in a roll is processed, and the curl is strong when the vicinity of the winding core is processed. Therefore, the curl is collected without being corrected. If it is attempted, the curl may be accumulated in the upper layer, or the film 14 may be bent. However, in the present embodiment, the pillow member 146
By curling the curl of the first film 14 by the above, the curls of the first film 14 are then corrected and accumulated, so that the curl can be surely accumulated regardless of the strength of the curl.

When a predetermined amount of the film 14 has been accumulated (up to about 900 sheets), the stopper member 154 is released and the accumulation box 1
Remove 42. At this time, since the film 14 is separated from the guide rod 144 by the contact plate 158, the guide rod 14 for taking out the film 14 from the stacking box 142.
The work of pulling out No. 4 becomes easy.

In this way, by inverting and accumulating the film 14, the title characters and symbols exposed together with the main image can be seen as a normal image from above, and the sorting operation can be easily performed.

Further, when the sheets are reversed and accumulated, the curls can be surely accumulated regardless of the strength of the curl, and there is no problem that the curls are accumulated and the film 14 is bent.

In this embodiment, the swing bat 10 is used.
Although the downstream side of 6 in the film transport direction is the lower position and the vicinity of the downstream end of the film transport direction is the center of rotation, the upstream side of the swing butt 106 in the film transport direction may be the lower position, and in this case, the upstream side of the film transport. The rotation center is near the side end.

Further, in this embodiment, a pair of pillow members 146 are arranged on the bottom portion 142A of the stacking box 142 to form the bottom portion 142A.
However, the film 14 to be accumulated has a so-called toyo shape, but this raised portion may be formed integrally with the bottom portion 142A.

Further, in this embodiment, the pair of exit rollers 44
The claw portion 108 is brought into sliding contact with the lower roller 44A of the lower mold, but as shown in FIG.
If the small-diameter portion 44B is formed in a portion corresponding to 8 to form a stepped roller, and the claw portion 108 is inserted into the small-diameter portion, the film 14 can be guided more reliably.

As described above, the film stacking box according to the present invention has an excellent effect that the curled film can be surely stacked.
