Abstract

PURPOSE:To surely deliver photosensitive plates one by one from an uppermost layer by installing a pressing means for pressing the photosensitive plate in the uppermost layer on a placing board onto a photosensitive plate in the next layer, sucking means, shifting means, angle changing means, and a separating means. CONSTITUTION:As for a receiving/delivery means 112, a grommet 162 and a sucking board 114 are projected in the A-direction by the driving revolution in an angle of theta1 of a motor 146, and the grommet 162 presses the vicinity of the lower edge part of a photosensitive plate 16 in the uppermost layer on a placing board 14, and after slightly deformed, said plate 16 is sucked by the sucking board 114. Therefore, the plate 16 in the uppermost layer is slightly deformed, and air is introduced between the next layer, and the plate 16 is separated from the next layer. After the adsorption by the sucking board 114, the motor 146 revolves by an angle theta2, and the negative pressure force is released over a hook 64. Therefore, the lower edge part of the plate 16 in the uppermost layer is dropped into the hook 64.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is used in a photosensitive plate auto feeder for feeding exposed photosensitive plates to an automatic developing machine.
Photosensitive plate delivery for the photosensitive plate auto feeder, which transfers the lower end of the photosensitive plate placed on the mounting table to the hook that supports the lower end of the photosensitive plate and feeds it into the automatic developing machine. Regarding equipment.

[Prior art] An automatic processor is used to process photosensitive plates (the photosensitive layer whose solubility changes with light irradiation is aluminum plate, zinc plate, iron plate, paper, etc.).
If a large number of photosensitive plates are to be processed continuously, a photosensitive plate auto feeder connected to an automatic processor may be used. sent.

Conventional photosensitive plate auto feeders are disclosed in JP-A-63-171728 and JP-A-63-106245, in which a plurality of photosensitive plates are placed vertically on a mounting table, and the lower end is supported by a support means. A photosensitive plate auto feeder has been proposed in which the photosensitive plate is separated from the mounting table by a separating means, the supporting means is raised by a lifting means, and the photosensitive plate is fed into an automatic developing machine. According to this device, since the photosensitive plate is placed vertically, the photosensitive plate can be quickly supplied to the automatic developing machine with a small installation space.

In this device, as shown in FIG.
A suction cup 190 that moves with the plate 8 tilted at about 15 degrees to the horizontal is used to move the top of about 20 photosensitive plates 194 placed on a mounting table 192 tilted at about 15 degrees to the vertical. The upper layer 9 is attracted and the lower end is supported by a hook 196 serving as a support means. The mounting table 192 is inclined at an angle of about 15 degrees with respect to the vertical direction because it is necessary to mount a plurality of photosensitive plates 194 in the vertical direction.

Further, the suction cup 190 moves linearly while adsorbing the photosensitive plate 194 while being inclined at about 15 degrees with respect to the horizontal direction.

Therefore, the photosensitive plate 194 is 1
It moves at an angle of 5 degrees and is transferred from the mounting table 192 to a hook 196 which is a supporting means.

However, when the photosensitive plate 194 is moved while being sucked by the suction cup 190 and tilted, both ends of the photosensitive plate 194 sag due to its own weight, vibration during movement, curling, etc., and are formed along the width direction 1 of the photosensitive plate 194. There is a problem in that the lower end of the hook 196 cannot be reliably accommodated in the groove of the hook.

Furthermore, when the photosensitive plate 194 is moved from the mounting table 192 using the suction cup 190, the suction cup 190 moves while tilting at a certain angle with respect to the horizontal direction while adsorbing the photosensitive plate. 194
There is a problem in that the lower end of the device rubs against the top of the mounting table, causing noise.

In order to solve this problem, it is conceivable to move the suction cup 190 not in a straight line, but to change its inclination angle with respect to the horizontal direction as it moves, so that both ends of the photosensitive plate do not sag.

On the other hand, since a plurality of photosensitive plates 194 are stacked on the mounting table, two photosensitive plates 194 may be transferred when they are sucked by the suction cup 190 and transferred. This is because the next photosensitive plate 194 is in close contact with the back side of the uppermost photosensitive plate, and two photosensitive plates 194 move at a time.

For this reason, before suctioning the photosensitive plate 194 with the suction cup 190, as shown in FIG. After pressing the suction cup 1
90 to slightly deform the uppermost photosensitive plate 194 and insert air between it and the next photosensitive plate 194 to prevent them from coming into close contact with each other to ensure that only one photosensitive plate 194 is moved. It looks like this.

[Problems to be Solved by the Invention] However, when the pusher for preventing two photosensitive plates from being fed is activated and the photosensitive plate is sucked and moved by the suction cup, the pusher also moves at the same time as the suction cup. However, even if the inclination angle of the suction cup relative to the horizontal direction is changed, the pusher continues to press the photosensitive plate, making it impossible to maintain the flatness of the photosensitive plate and preventing both ends of the photosensitive plate from sagging. The problem arises that it cannot be done. For this reason, it is not possible to reliably transfer the photosensitive plates one by one to the hook.

In consideration of the above facts, the present invention provides a photosensitive plate delivery device for a photosensitive plate auto feeder that can reliably transfer a plurality of photosensitive plates stacked on a mounting table to a hook one by one starting from the top layer. The purpose is to

[Means for Solving the Problems] In order to achieve the above object, the present invention includes a pressing means for pressing the uppermost photosensitive plate on the mounting table to the next layer photosensitive plate, and a pressing means for adsorbing the photosensitive plate. a suction means; a moving means for driving the suction means to move the lower end of the photosensitive plate to the hook and moving the pressing means in the same direction; angle changing means for changing the inclination angle of the photosensitive plate with respect to the inclination angle of the photosensitive plate placed on the mounting table and supporting the lower end of the photosensitive plate to the hook; and a pressing means that moves together with the suction means by the moving means. and a separating means for separating the photosensitive plate from the photosensitive plate after the photosensitive plate is separated from the mounting table.

[Function] According to the present invention having the above configuration, the uppermost photosensitive plate stacked on the mounting table is pressed by the pressing means and sucked and attached by the suction means.

In this state, air enters between the uppermost photosensitive plate and the next photosensitive plate, preventing the photosensitive plates from coming into close contact with each other.

In this state, the moving means starts moving the suction means and the suppressing means. After the photosensitive plate is separated from the mounting table, the pressing means is separated from the photosensitive plate by the separating means. Thereafter, the suction means moves along the movement trajectory while changing the angle with respect to the horizontal direction, and transfers the lower end of the photosensitive plate to the hook. The photosensitive plate, whose lower end is supported by the hook, is sent into the automatic developing machine by the upward movement of the hook.

Since the pressing means presses the uppermost photosensitive plate before the lower end of the photosensitive plate is suctioned by the suction means, feeding of two photosensitive plates is prevented. Further, when the photosensitive plate is delivered to the hook by the suction means, the suction shaft of the suction means changes from a state where it is inclined with respect to the horizontal direction to a substantially horizontal state by the angle changing means,
When the lower end of the photosensitive plate is supported on the hook,
The photosensitive plate is delivered in a substantially vertical position.

This prevents both ends of the photosensitive plate from being exposed to its own weight, vibration,
Since the photosensitive plate does not sag due to curling or the like, the lower end of the photosensitive plate can be reliably supported by the supporting means.

Furthermore, the angle changing means transfers the photosensitive plate from an inclined state to the vertical direction to a substantially vertical state, so the lower end of the mounting table and the photosensitive plate do not slide, and no sound is generated. .

[Example] Fig. 2.3 shows a photosensitive plate auto feeder 10 using a photosensitive plate delivery device 112 for a photosensitive plate auto feeder according to the present invention, and an automatic developing machine 12.
Shown connected to. In the photosensitive plate auto feeder 10 of this embodiment, a large number of photosensitive plates 16 exposed in a separate process are stacked and stacked vertically on a mounting table 14 inclined with respect to the vertical direction. 18, the images are sequentially sent to the automatic developing machine 12.

The mounting table 14 has protrusions 22 on both sides of the frame 200 (however, the protrusions 22 on the near side are not shown in FIG. 3).
Support pieces 24 are respectively protruded from the lower ends, and the lower ends of the exposed photosensitive plates 16 are sequentially placed on the support pieces 24. The angle of inclination of the frame 20 from the vertical is approximately 15
It is set at a certain degree. For this reason, the exposed photosensitive plate 16 is sequentially polymerized from the right side in FIG. 3, with the uppermost layer facing the separation supporter 18.

In this case, it is preferable for the photosensitive plate 16 which has a photosensitive surface on one side of each support to face the opposite side of the separation supporter 18 in order to protect the photosensitive surface.

As shown in FIG. 2, a pair of side plates 28 and 30 are erected on both sides of the separating support upper part 18.
．． 30 are connected to each other by a bottom plate 32 at their lower ends. As shown in FIG. 3, these side plates 28 and 30 are connected at their upper ends by a support shaft 34 and at their lower ends by support shafts 36 and 38, so that they are parallel to each other.

Posts 40 are respectively projected from the opposing surfaces of the side plates 28, 30, and inner guide plates 42 are fixed to the tips of these posts 40, respectively.

Therefore, these inner guide plates 42 are connected to the pair of side plates 28.3.
0 and are parallel to each other, and the inner guide plate 4
The two are connected by a plurality of support shafts 44.

A plurality of guide rings 46 are supported on each of these support shafts 44 at regular intervals. These guide rings 46 are for supporting the photosensitive plate 16 separated from the mounting table 14, and as shown in FIG. The guide ring 46 that is pivotally supported on the shaft 44 is gradually separated from the mounting table 14, and the photosensitive plate 16 separated from the mounting table 14 is supported with respect to the vertical axis opposite to the supporting angle to the mounting table 14. It can be supported at an angle.

Support plates 48 are attached to the plurality of support shafts 44 with screws 50, and a plurality of notches 52 are formed in these support plates 48 to allow a part of the guide ring 46 to protrude toward the mounting table 14 side. has been done. As a result, the photosensitive plate 16 supported on the guide ring 46 may be inadvertently moved to the third position.
In the figure, care is taken to prevent the guide ring 46 from being pulled out to the left side.

A rotary shaft 54 is supported parallel to the side plates 28 and 30 between the second and third support shafts 44 from the top of the plurality of support shafts 44, and a sprocket wheel 56 is fixed. These sprocket wheels 56 are arranged above the inner guide plate 42, and an inner chino 60 is wound around each sprocket foil 56. This inner chino 60 is the support shaft 3
The other part is wrapped around a sprocket foil 62 fixed to the sprocket wheel 8, and moves along the surface of the inner guide plate 42 between the sprocket foil 56 and the sprocket foil 62.

This inner chino 60 has a hook 64 fixed at its longitudinal end. This hook 64 has a 7-shaped side surface as shown in FIG. The uppermost photosensitive plate 1 of the plurality of photosensitive plates 16 installed on the mounting table 14
This is for accommodating the lower end of 6.

Further, a motor 66 is attached to the rotating shaft 54,
The rotating shaft 54 is rotated clockwise and counterclockwise in FIG. Therefore, the hook 64 is located at the third position of the sprocket wheel 62.
By rotating counterclockwise in the figure, the photosensitive plate 16 containing the lower end can be lifted and sent toward the automatic developing machine 12 while being guided by the rotation of the guide ring 46.

Movement of the hook 64 is restricted by a lower limit switch 58A1 attached near the sprocket wheel 62 and an upper limit switch 58B attached near the sprocket wheel 56.

As shown in FIG. 4, between the side plates 28, 30 and the inner guide plate 42, a sprocket foil 70, a sprocket foil 72, and a sprocket foil 72 are attached to the support shaft 34 and the support shaft 38, respectively, when viewed from the front. Hesprocket foils 74 are attached and outer chains 76 are wrapped around each. These outer chinos 76 are rotatable clockwise and counterclockwise in FIG. 3 under the driving force of a motor (not shown) connected to the support shaft 38.

These outer chinos 76 are guided by an outer guide plate 80 disposed between the support shaft 34 and the support shaft 38. These outer guide plates 80 extend above the support shaft 38 in parallel with the inner chain 60, and above the inner chain 60 are bent into an arc shape, the extension of which forms a tangent to the pitch circle of the sprocket wheel 70. are doing.

Further, a plurality of connecting shafts 82 are extended between the outer teeth 776, and guide rings 84 similar to the guide ring 46 are supported at equal intervals in the intermediate portions of these connecting shafts 82.

Therefore, these guide rings 84 are attached to the photosensitive plate 1.
When the lower end of the photosensitive plate 16 is mounted on the hook 64 and rotated counterclockwise in FIG. It can be moved.

Note that a notch 85 (see FIG. 2) is formed in a portion of the hook 64 through which a guide ring 84 passes.

In order to control the stroke of the outer cholera 76, an upper limit switch 86 and a lower limit switch 88 (not shown) are arranged near the sprocket wheel 70 and the sprocket wheel 72, respectively.

A photosensitive plate detection switch is attached to a stay (not shown) on the leading edge and the next connecting shaft 82 attached to the outer chino 76 that moves counterclockwise in FIG. The tip of the photosensitive plate 16 transferred to the plate 18 can be detected.

A pair of clamping rollers 92 and 94, which constitute a part of the automatic developing machine 12, are arranged adjacent to the sprocket wheel 70, and grip the leading end of the photosensitive plate 16 that is raised along the separating support section 18. The film is then fed into the automatic developing machine 12.

Therefore, these clamping rollers 92 and 94 are connected to the automatic developing machine 1.
It has the same peripheral speed as the developing speed in 2.

A transfer device 112 is provided in the lower part between the side plates 28 and 30.

This delivery device 112 includes
As shown in the figure, a pair of suction cups 114 and 116 are arranged to suction the photosensitive plate 16. These suction cups 114 and 116 are attached to the tip of the support shaft 118, and are supplied with negative pressure from a negative pressure source (not shown) to suction the photosensitive plate 16.

The support shaft 118 passes through the support bracket 120 and is slidable with the support bracket 120. Support shaft 118
An E IJ song 22 (see Figure 5) is attached to the middle part of the E IJ song 22 and the support bracket 1.
20, a compression coil spring 124 is interposed. Therefore, when the support bracket 120 is pushed toward the mounting table 14 and the suction cups 114 and 116 are pressed against the photosensitive plate 16, the support bracket 120 that moves further is moved by the compression coil spring. While compressing the spring 124, the suction cups 114 and 116 are pressed against the photosensitive plate 16 by the elastic force of the compression coil spring 124.

The support bracket 120 is pivotally supported by pins 128 on both sides of a support arm 1260 disposed between the support brackets 120, and is swingable around the pins 128.

The support arm 126 is formed long along the width direction of the mounting table 14, and has suppression rods 130 connected to both ends thereof. The middle part of this pressing rod 130 is supported by a bearing 134 attached to a base plate 132.
It is guided by this bearing 134 and can slide.

One end of a long link 138 is pivotally supported by a pin 136 at a widthwise intermediate portion of the support arm 126 . This long link 13
The other end of 8 is pivotally supported by a pin 140 to one end of a short link 142. The other end of the short link 142 is fixed to a rotating shaft 144, which is connected to the output shaft 1 of the motor 146.
48.

Therefore, the rotation of the motor 146 is transmitted as the rotational force of the short link 142, and the long link 138 receives this rotational force via the pin 140.
A reciprocating slider crank mechanism is configured to reciprocate the slider 22.

Here, the axial center of the rotating shaft 144 is arranged offset from the movement extension line of the reciprocating pin 136, thereby forming a rapid feed mechanism. That is, as shown in FIG. 6, the forward stroke and return stroke of the reciprocating movement of the pin 13G correspond to the rotation angle θ weight and θ2 of the short link 1420. Therefore, the rotation speed of the rotating shaft 1440, which rotates at a constant speed, is such that the rotation angle of zero fold corresponds to the forward stroke of the suction cup 114, 116, and the angle θ2, which is larger than this, corresponds to the return stroke, so the suction cup 114.
11B can quickly approach the mounting table 14, attract the photosensitive plate 16, and pull the attracted photosensitive plate 16 toward the hook 64 at a slower speed.

One end of a connecting arm 150 is connected to the upper end of the support bracket 120 . A pin 152 is attached to the other end of the connecting arm 150.

The pin 152 is inserted into a cam groove 156 of a cam plate 154 that stands up from the base plate 132, and the pin 152 moves along the cam groove 156 when the support arm 126 reciprocates. As a result, the support arm 120 swings about the pin 128 and stores the lower end of the photosensitive plate 16 into the hook 64 with the lower end of the photosensitive plate 16 in a substantially vertical state.

As shown in FIG. 8, the support arm 126
4, the pin 152 is located at one end 156A of the cam groove 156, and at this time, the suction cups 114 and 116 are at an angle α,
It is sloping. The angle α is set to approximately 5°. Also, the position where the support arm 126 is closest to the mounting table 14 (
8), the pin 152 is located at the other end 156B, and at this time the suction cups 114 and 116 are tilted at an angle α2 with respect to the horizontal direction, and this α2 is It is set at approximately 15°. In this state, it is located parallel to the surface of the photosensitive plate 16 on the mounting table 14.

In addition, a step is formed in the middle part of the cam groove 15G,
When the pin 152 moves within this cam groove 156, the support bracket 120 moves to the pin 128 via the connecting arm 150.
It oscillates in the range of about 15 degrees to about 5 degrees around the center.

After suctioning the photosensitive plate 16, these suction cups 114 and 116 move the photosensitive plate 1 above the hook 64.
6 is moved, the negative pressure is released and the lower end of the photosensitive plate 16 is moved to the hook 64. In this case, only the uppermost photosensitive plate 16 of the photosensitive plates 16 mounted on the mounting table 14 is suctioned by the suction cups 114 and 116, but this uppermost layer photosensitive plate 16 and the next layer are If the photosensitive plate 16 is in close contact with the top layer photosensitive plate 16, the next layer photosensitive plate 16 may be inadvertently pulled out while remaining in close contact with the top layer photosensitive plate 16. Therefore, after the suction cups 114 and 116 have suctioned the photosensitive plate 16, they are moved slightly to the left in FIG. 3 and then stopped temporarily.
It is preferable to allow time for outside air to enter between the top and bottom layers, so that the next layer of photosensitive plates can separate from the uppermost photosensitive plate 16 and slide down under its own weight, remaining on the support piece 24.

Furthermore, for this purpose, a photosensitive plate) 1 is applied onto the support piece 24.
It is preferable that a tape 158 provided with a plurality of small protrusions is pasted toward the end face of 6.

This tape 158 can be made of a material such as Velcro tape (trade name) having a plurality of small protrusions protruding from one side thereof. This provides a movement resistance force to the lower end surface of the photosensitive plate 16 that is attracted by the suction cups 114 and 116, and the next layer photosensitive plate 16 that moves inadvertently without swaying under the attraction force. The top layer of photosensitive plate 1
It can be separated from 6.

Furthermore, as is clear from Fig. 2, the suction cups 114 and 116
The 0 interval is 1/ of the width of the separation holding part 18 and the mounting table 14.
2 or less, and among the multiple types of photosensitive plates 16 used, the photosensitive plate [6] with the smallest width dimension is
It corresponds to In order to suction a photosensitive plate 16 with a large width dimension, it is preferable to provide a larger number of suction cups or to widen the spacing between the suction cups 114 and 116. 16, the next layer, the wide photosensitive plate 16, will also be suctioned, so the suction cup 114 should be
．． The interval of 116 is fixed.

Further, as shown in FIG. 6, the tape 158 is attached to the suction cup 1.
It is preferable to attach it to the support piece 24 corresponding to the part between 14 and 116. If the suction cups 114 and 116 are provided at a position away from the space between the suction cups 114 and 116, resistance will be given to the movement of the photosensitive plate 16 when the suction cups 114 and 116 move by suction.
The bending of both ends of the photosensitive plate 16 in plan view is thick (
As a result, the bent end portion causes people not to enter the hook 64.

Further, as shown in FIGS. 1, 4, and 5, a press rod 160 is slidably connected to the intermediate portion of the support arm 126 through the support arm 126. As shown in FIGS. The distal end protruding through the support arm 126 has a
A grommet 162 is attached. This grommet 162 is molded from a relatively flexible material so as to come into contact with the surface of the photosensitive plate 16. This grommet 16

is provided to urge the grommet 162 toward the photosensitive plate 16. For this reason, the pressing rod 160
The photosensitive plate 16 is also biased toward the photosensitive plate 16 .

An end of the suppression rod 160 opposite to the grommet 162 is supported by a stopper 166. A bottle 168 protrudes from both sides of the stopper 166, and a pressing rod 160
The lever 170 is supported via a bearing 172 between the upper ends of a pair of levers 170 arranged on both sides.

The lever 170 is connected to a pair of connecting brackets 172 and 1
It is pivotally supported via 76. The connecting bracket 172 is connected to the movable bracket 174 with screws 173.

The movable bracket 174 has a flat plate shape, and both ends of the movable bracket 174 are bent downward to form a bent portion 174A. The connecting bracket 172 is inserted into the bent portion 174 and connected. Further, a guide plate 175 is fixed to one bent portion 174A with screws 173. The other side of the movable bracket 174 is fixed to the lower end of the support arm 126 with a screw 177. Therefore support arm 1
26 moves toward the mounting table 14, the lever 170,
The pressing rod 160 also moves toward the mounting table 14.

Further, a hollow stay 178 is arranged between the levers 170, and a bottle 180 passes through it.

Both ends of the bottle 180 protrude outward between the levers 170 and are supported by the levers 170. One end of the bottle 180 further protrudes, and a roller 18 is attached to the tip.
2 is installed.

The roller 182 is inserted into a cam groove 186 of a cam plate 184 that stands up from the base plate 132.

As shown in FIGS. 4 and 7, the cam groove 186 is formed along the moving direction of the lever 170, and a step is provided at the intermediate portion connecting the lower groove 186A and the upper groove 186B. .

Therefore, when the lever 170 moves toward the mounting table 14 (in the six directions of arrows shown in the figure), the roller 182 is guided by the cam groove 186 and moves from the lower groove 186A to the upper groove 186B.
When the lever 170 is moved to the position, the lever 170 swings clockwise in FIG.
direction). Further, when the lever 170 moves in the direction away from the mounting table 14 (in the direction of arrow B), the roller 182 moves within the cam groove 186, and when it moves from the upper groove 186B to the lower groove 186A, the lever 170 moves
The pressing rod 160 swings counterclockwise in FIG.
is moved in the direction of separating it from the mounting table 14 (in the direction of arrow B in the figure). In this case, the support arm 126 is also connected to the lever 170.
Similarly, the suction cups 114 and 116 are separated from the mounting table 14 and moved in the same direction. However, halfway through, the pressing rod 160 moves in the direction of arrow B due to the swinging of the lever 170, so it becomes retracted from the suction cups 114 and 116.

Therefore, from the photosensitive plate 16, the grommet 162
are separated and are sucked by suction cups 114 and 116,
Moving.

Next, the operation of this embodiment will be explained.

As shown in FIG. 3, in the initial state, the hook 64 is stopped on the side of the sprocket wheel 62 and facing the mounting table 14, and the outer chino 76 has a guide ring 84 at the forefront of the hook 64. It is arranged horizontally.

Here, a plurality of exposed photosensitive plates 16 are stacked and mounted vertically on the mounting table 14.

The delivery means 112 has an angle θ of the motor 146.

Due to the drive rotation of the grommet 162, suction cup 114.
116 protrudes to the right (six arrow directions) in FIGS. 8, 6, and 7 (the position indicated by the two-dot chain line in FIG. After slightly deforming the photosensitive plate 16 by pressing near the lower end of the photosensitive plate 16 (the position indicated by the two-dot chain line in FIG. 7),
It is sucked by suction cups 114 and 116. As a result, the uppermost photosensitive plate 16 is slightly deformed, air is inserted between it and the next layer, and the uppermost photosensitive plate 16 is separated from the next layer. After being sucked by the suction cups 114 and 116, the motor 146 rotates by an angle θ2 and the suction cups 114 and 11
6 returns to the left in FIG. 8, releasing the negative pressure above the hook 64.

As a result, the lower end of the uppermost photosensitive plate 16 falls into the hook 64.

When the suction cups 114 and 116 adsorb the lower end of the photosensitive plate 16 and move, the support bracket 120
The suction cup 114.11 swings according to the cam groove 156.
Since the suction surface of 6 is swung, the photosensitive plate 16 is
Both ends of the photosensitive plate 1 do not hang down.
The rigidity of the hook 6 allows the hook 6 to maintain its flat state.
The lower end is received into 4. This ensures that the photosensitive plate 16 is transferred to the hook 64.

Furthermore, the suction cups 114 and 116 swing after adsorbing the lower end of the photosensitive plate 16 on the mounting table 14 and move by lifting the lower end from the mounting table, so that they do not slide on the mounting table 14. There is no sound generation.

Further, when the suction cups 114 and 116 suction the lower end of the photosensitive plate 16 and move, the pressing rod 160 moves from the upper groove 186B of the roller 182 to the lower groove 186A, so that the lever 170 is moved in the opposite direction in FIG. By swinging clockwise, the suction cups 114 and 116 move in the direction of arrow B faster than the movement of the suction cups 114 and 116, and are separated from the photosensitive plate 16. As a result, when the photosensitive plate 16 is transferred by the suction cups 114 and 116, the photosensitive plate 16 is not deformed, and the suction cups 114 and 116 ensure that the photosensitive plate 16 is photosensitive while maintaining the flatness of the photosensitive plate 16. The lower end of the plate 16 can be transferred to the hook 64.

Here, the motor 78 is driven, and the outer chino 76 rotates counterclockwise in FIG. 3. For this reason, the uppermost photosensitive plate 16 whose lower end is housed in the hook 64 is moved upward by the guide ring 84 sequentially moving up the photosensitive surface (the right surface in FIG. is gradually separated from the mounting table 14 from the lower part to the upper part, and is moved to the upper part of the separating support part 18, so that the anti-photosensitive side comes into contact with the plurality of guide rings 46.

In this case, the lower end of the photosensitive plate 16 is accommodated in the stationary hook 64, so that the guide ring 8
The photosensitive plate 16 can be stably supported even when the photosensitive plate 4 is raised. If this hook 64 is also attached to the outer chain, that is, if the inner chain 60 is omitted, the suction cups 114 and 116 will hold the photosensitive plate until the hook 64 corresponds to the lower end of the photosensitive plate 16. 1
6 must be held, so the holding force of the suction cup must be increased.

When the photosensitive plate detection switch 68 guided by the guide ring 84 at the tip rises along the photosensitive surface side of the photosensitive plate 16 and detects the upper end of the photosensitive plate 16, the motor 66 is also driven and the inner chino 60 moves to the outer side. It rotates counterclockwise in FIG. 3 at the same speed as the chino 76. This causes the hook 64 to rise and lift the photosensitive plate 16.

Therefore, the guide ring 84 at the tip gradually bends the upper end of the photosensitive plate 16 in the horizontal direction along the outer guide part 80 while holding the upper end of the photosensitive plate 16 between the guide ring 46 and the holding roller 92. .94 between.

In this case, the motor 78 and the motor 66 rapidly raise the photosensitive plate 16, and when the tip of the photosensitive plate 16 reaches just before the clamping rollers 92, 94, the guide ring 84 at the tip is activated by the upper limit switch. When detected,
It is preferable to rotate at a low speed, thereby reducing the working time. This low speed is caused by the clamping roller 92
．． The rotation speed is set to be slower than the rotation speed of 94 so that the leading end of the photosensitive plate 16 can be smoothly fed.

When the tip of the photosensitive plate 16 is clamped by the clamping rollers 92, 94, the motor 66 is reversed, rotating the inner chain 60 counterclockwise in FIG. 3, and the hook 64 is in the state shown in FIG. Stop. The reverse rotation of the motor 66 may be started after a predetermined time delay after the upper limit switch 86 detects the guide ring 84. On the other hand, outer chain 7
6 is stopped until the rear end of the sent photosensitive plate 16 passes near the sprocket foil 56, and the rear end of the photosensitive plate 16 becomes straight due to its rigidity, and the next layer on the mounting table 14 is stopped. This prevents the problem of contact with the photosensitive plate 16. At this point, the outer chino 76 is reversed and the guide ring 84 at its tip returns to the state shown in FIG. 3 in preparation for adsorption of the next layer of photosensitive plate 16. Stopping and reversing of the outer chain 76 may be started after a predetermined time delay after the upper limit switch 86 detects the guide ring 84.

Note that the photosensitive plate 16. 3, the frame 20 is rotated around the left or right end of the frame 20 to make it easier to mount the separating support part 18.
A rotating shaft may be provided to increase the distance between the two.

[Effects of the Invention] As explained above, according to the present invention, the uppermost layer of a plurality of photosensitive plates placed on the mounting table is pressed by the pressing means, and the uppermost layer of the photosensitive plates is adsorbed by the suction means. When moving the photosensitive plate from the mounting table in this state, the suppressing means is moved away from the photosensitive plate faster than the suction means moves, so the lower end of the photosensitive plates stacked on the mounting table is It has the excellent effect of being able to reliably transfer the sheets one by one from the upper layer to the hook.
