After that, the photographing tool 16 moves from the photographing position to the photographing start position by the fluid pressure cylinder 17f in a state of photographing the outer peripheral edge portion of the interleaving paper P ', and continuously from the photographing start position by the rodless cylinder 17c. Move horizontally to the standby position. As a result, the interleaving paper P ′ taken by each of the photographing tools 16 is sequentially rolled up from the plate material P. Then, when the photographing tool 16 returns to the standby position, one side of the outer peripheral edge of the interleaving paper P ′ rolled up from the plate material P is sandwiched between the lower roller 18a and the upper roller 18b, and The photographing state of the interleaving paper P ′ by the photographing tool 16 and the vacuum suction state of the interleaving paper P ′ by the vacuum suction holes 16e formed in the claws 16a and 16b are released. Finally, the rollers 18a, 18b,
The rollers 18c and 18d are rotationally driven in the direction in which the interleaving paper P'is discharged by the roller driving device. This allows the roller 18
The interleaving paper P ′ sandwiched between a and 18b is completely rolled up from the plate material P and discharged to the outside of the dark box 3, and the interleaving paper receiving port 1a formed in the light-shielding cover 1 inserts the interleaving paper receiving cart. 15 will be discharged.

In the exposure device B, a table 20, a plate material drawing mechanism 21, an exposure drum 22, and a plate material winding roller 2 are provided on a frame 19 installed adjacent to the plate supply device A on the downstream side.
3 and a pair of exposure devices 24 (laser light scanning heads), etc., respectively, and the entire frame 19 is covered with a metal light-shielding cover 25 having a door that can be opened and closed. A drawing image signal (digital signal) from (not shown) is sent to the exposure device 24 via a drawing controller (not shown), and laser scanning corresponding to the image signal is performed by the plate material P (photopolymer plate, silver salt plate, etc.). The image drawing signal is drawn as a latent image on the plate material P by being performed on the photosensitive surface. This exposure apparatus B is disclosed in Japanese Patent No. 3105217.
The structure is similar to that of the structure disclosed in the publication.

That is, the exposure apparatus B, as shown in FIG.
A table 20 which is swingably supported in the vertical direction by a frame 19 via a bearing 26 and receives the plate material P sent from the plate supply device A, and a fluid pressure cylinder 27 which swings the table 20 in the vertical direction. , Provided on the table 20,
Positioning and pushing mechanism 28 including a plurality of movable pins 28a for positioning and feeding the plate material P on the table 20.
And a plate material drawing mechanism 21 including a plurality of vacuum suction plates 21a for drawing the plate material P onto the table 20 and two cylinders 21b and 21c, and a plate material retracting mechanism 21 arranged at a lower position on the upstream side of the table 20 so as to be rotatable forward and backward. And an exposure drum 22 around which the plate material P on the table 20 is wound,
And a gripper mechanism 29 for fixedly holding the upstream end of the plate material P on the outer peripheral surface of the exposure drum 22, and the exposure drum 2.
A vacuum suction unit 30 that is provided on the second suction unit 2 and that suction-holds the downstream end of the plate P on the outer peripheral surface of the exposure drum 22 by vacuum suction.
A plate material winding roller 23 that is swingably arranged in the vertical direction, a fluid pressure cylinder 31 that rocks the plate material winding roller 23, and an exposure drum 22 at a position downstream of the exposure drum 22. A pair of right and left exposure units 24, which are provided so as to be movable in parallel to the axis and directly expose the plate material P, which is wound around the exposure drum 22, with a drawing corresponding to a drawing image signal from a computer; Is composed of a drive device 32 (comprising a ball screw mechanism, a servomotor, etc.) for reciprocating the exposure drum 22 along the axis of the exposure drum 22.

Thus, according to the exposure apparatus B, the downstream end of the plate material P on the plate material receiving shelf 8 located at the plate material feeding position is located on the exposure apparatus B side by the plate material feeding mechanism 14. Table 2
When it is sent to 0, the suction plate 21a of the plate material drawing mechanism 21 first sucks and holds the downstream end of the plate material P by vacuum suction, and in this state, the suction plate 21a is placed in a horizontal posture by the cylinder 21b. The table 20 is moved from the upstream side to the downstream side, and the suction plate 21 is moved to a position downstream of the table 20.
The vacuum holding state of a is released. As a result, the plate material P fed into the exposure apparatus B from the plate material inlet 25a of the exposure apparatus B is completely placed on the table 20 of the exposure apparatus B. At this time, the positioning and pushing mechanism 28 operates to position the plate material P on the table 20. Next, the table 20 is swung by the fluid pressure cylinder 27 from the horizontal position to the inclined position, and the upstream end of the table 20 is positioned near the outer peripheral surface of the exposure drum 22. In this state, the plate material P on the table 20 is pushed toward the exposure drum 22 by the positioning and pushing mechanism 28, and the upstream end of the plate material P is fixedly held on the outer peripheral surface of the exposure drum 22 by the gripper mechanism 29. After that, the plate material winding roller 23 swings downward to come into contact with the end surface of the plate material P, and the exposure drum 22 is rotated in the winding direction of the plate material P by a servomotor (not shown). As a result, the plate material P is sequentially wound around the exposure drum 22 with its photosensitive surface facing outward. When the downstream end of the plate material P is wrapped around the outer peripheral surface of the exposure drum 22, the vacuum suction unit 30 operates and the downstream end of the plate material P is suction-held on the outer peripheral surface of the exposure drum 22. When the plate material P is completely wound around the outer peripheral surface of the exposure drum 22, the table 20 in the inclined position is swung to the horizontal position by the fluid pressure cylinder 27, and the plate material take-in roller which is in contact with the plate material P. After 23 swings upward,
The exposure device 24 moves along the exposure drum 22 by the driving device 32, and the exposure device 24 draws (exposes) on the plate material P. When the drawing process of the plate material P wound around the exposure drum 22 is completed, the plate material winding roller 23 swings downward to come into contact with the surface of the plate material P, and the plate material P by the vacuum suction unit 30. The suction holding of the downstream side end of the exposure drum 22 is released, and the exposure drum 22 is rotated by the servomotor in the direction of feeding the plate material P. As a result, the exposure drum 22
The plate material P wound around is sequentially removed from the exposure drum 22 and sent to the plate discharge device C located on the downstream side. Finally, the holding and holding mechanism 29 releases the upstream side end of the plate material P from being fixedly held, and the plate material P wound around the exposure drum 22 is completely transferred to the plate discharge device C with its photosensitive surface facing upward. Sent in.

The plate discharge device C receives the exposed plate material P sent from the exposure device B and receives the exposed plate material P, and the subsequent developing device E.
And is disposed adjacent to a position on the downstream side of the exposure drum 22 above the exposure device. As shown in FIG. 13, the plate discharge device C has a table 33 for receiving the exposed plate material P sent from the exposure drum 22.
And a belt conveyor 34 for sending the plate material P on the table 33 to the subsequent developing device E. The table 20 has a plurality of plate members for positioning the plate material P on the table 20 at a predetermined position. The reference pin 35 is provided so as to be able to project to the upper surface of the table 20.

The direction changing device D is provided in the succeeding developing device E.
The posture of the plate material P is changed so that the rubber roller is not worn out, or the posture of the plate material P is changed so that the punch bender F can easily process the plate material P.
Specifically, as shown in FIG. 13, the direction changing device D is disposed above the plate discharging device C, and the plate material P on the plate discharging device C is disposed.
One or two of them are rotated at the same time by 90 degrees, and a rotary shaft 42 that is rotatably and vertically movable above the plate discharging device C, and a frame body 36 attached to the lower end of the rotary shaft 42, Attached to the frame body 36 at appropriate intervals,
It is composed of a plurality of vacuum suction plates 37 that suction-hold the plate material P on the plate discharging device C by vacuum suction, a fluid pressure cylinder 38 that rotates the rotating shaft 42 and the frame body 36 by 90 degrees, and a link 39. The reason why the posture of the plate material P is changed is that in the developing device E, two plate materials P each having a size of two pages of a newspaper are simultaneously developed with the long side thereof extending along the longitudinal direction of the plate making device. When it is fed into the apparatus E, the rubber roller in the developing section is unevenly worn in a slight gap between both plate materials P, and development unevenness is generated when the plate material P having a size of four newspaper pages is developed. Is. Further, in the punch bender F, the punching process and the bending process are performed at both ends in the longitudinal direction of the plate material P at the position in the width direction of the plate making device.
This is because if the sheet is fed to the punch bender F with its long side extending along the conveying direction of the plate material P, both ends of the plate material P cannot be processed.

The developing device E has a case 40 in which a heating part, a developing part, a water washing part, a gumming part, a drying part and the like are housed, and the latent image part of the plate surface formed by the exposure device B is stored. After heat fixing in the heating part, the high-sensitivity photopolymer layer other than the image part fixed using an alkaline solution in the developing part is removed to form a printing plate surface for printing, and finally in the water front part and gumming part. The plate surface is protected by washing with water or applying a gum solution.

The punch bender F has positioning holes for the plate cylinder of the printing press at the upper and lower ends of the developed printing plate, and folds for mounting on the plate cylinder at the upper and lower ends of the plate. The locking pieces are formed respectively, and are installed adjacent to the downstream side of the developing device E. This punch bender F has
The applicant first applied for a patent (Japanese Patent Application No. 2000-33982).
2) Punch bender F is used. That is, the punch bender F has a movable and adjustable table 41 for supporting and placing the plate in a horizontal posture, an image sensor camera (not shown) for detecting the position of a marker mark formed on the plate on the table 41, A punch mechanism (not shown) is formed at the upper and lower ends of the plate to form positioning holes on the plate cylinder of the printing press, and a punch mechanism is provided at both upper and lower ends of the plate for mounting the printing press on the plate cylinder. It is composed of a bender mechanism (not shown) that forms a bent locking piece, and the image sensor camera detects the position of the marker mark of the printing plate on the table 41 and moves the table 41 based on the detected value. After adjustment to adjust the position of the printing plate, a punching mechanism and a bender mechanism are used to form a positioning hole and a bending locking piece at both upper and lower ends of the printing plate.

The plate-making device G receives the plate materials P (printing plates) sent from the punch bender F and stores them in a stacked state in a vertical posture.
It is installed adjacent to the downstream side of.

Next, the case where the plate material P is supplied to the exposure device B by using the plate supply device A having the above-described structure will be described.
First, the packaged unexposed plate material P is unpacked in a common dark room installed at a different place from the plate making device, and the unexposed plate material P taken out is stored in a dark box 3 on a carrier in the dark room. The main body 3a of the dark box 3 is covered with the lid 3a so as to prevent light from entering the dark box 3.

Next, the dark box 3 placed on the transporting vehicle is transported by the transporting vehicle through the light chamber to a position near the plate feeding apparatus A on the upstream side of the plate making apparatus, and is formed on the light shielding cover 1 of the plate feeding apparatus A. The opening / closing port (not shown) is opened, and the dark box 3 on the carrier is put into the space surrounded by the light blocking cover 1 from the loading / unloading port of the light shielding cover 1 and placed on the support 2a.

In the same manner, the dark box 3 containing the unexposed plate material P is transported by the transport vehicle through the light chamber to a position near the plate-making apparatus, and in the space surrounded by the light-shielding cover 1 by the procedure described above. Are arranged in parallel in the width direction of the plate making apparatus on the support base 2a. If you put the dark box 3 on all the supports 2a,
The door provided on the light shielding cover 1 is closed to close the access port.

When a plate material P having a specific size, for example, a plate material P having a size of four newspaper pages is requested, first, the suction portion of the plate material take-out device 6 located above the large dark box 3 is first requested. 9
So that the tray can be lowered, the lid temporary storage shelf 7 and the plate material receiving shelf 8
Respectively move horizontally to the retracted position (in this case, the position above the small dark box 3).

When it is confirmed by a sensor (not shown) that the temporary lid placing rack 7 and the plate receiving rack 8 are not located above the large dark box 3, the suction portion 9 of the plate taking-out device 6 descends to drop the dark box 3. After suction-holding the lid 3b of the vacuum suction by vacuum suction, the suction temporary storage shelf 7 with the suction portion 9 holding the lid 3b of the dark box 3
Rises to a position (adsorption start position) slightly higher than the height of and stops at that position. As a result, the large dark box 3 is opened.

Next, the temporary lid placing rack 7 in the retracted position is horizontally moved to the lid receiving position (the position directly below the suction portion 9 holding the lid 3b by suction) and stopped at that position. The vacuum holding state of the suction unit 9 is released, and the lid 3b of the dark box 3 is released.
Is delivered to the temporary lid storage shelf 7. The temporary lid placing rack 7 that has received the lid 3b of the dark box 3 horizontally moves again to the retracted position (the position above the small dark box 3).

Subsequently, the interleaf sheet take-out device 5 is operated to remove the interleaf sheet P'on the plate material P located at the uppermost position in the dark box 3 to the outside of the dark box 3 and discharge it into the interleaf sheet trolley 15. The part 9 descends again from the suction start position and the unexposed plate material P
After sucking and holding the plate material P, the suction portion 9 rises to a position (standby position) slightly higher than the height of the plate material receiving shelf 8 while holding the plate material P by suction.

After that, the plate material receiving shelf 8 in the retracted position is horizontally moved to the plate material receiving position (the position directly below the suction portion 9 which holds the plate material P by suction), and stops at that position. Then, the vacuum holding state of the suction portion 9 is released, and the plate material P is delivered to the plate material receiving shelf 8. The plate material receiving rack 8 that has received the plate material P moves horizontally to the plate material feeding position (the same position as the retracted position), and the plate material P on the plate material receiving rack 8 is exposed by the plate material feeding mechanism 14. Push in to the B side.

Then, when the plate material P of the same size is continuously supplied to the exposure device B, the slip sheet take-out device 5 is activated again and the slip sheet P'for protecting the plate material P in the dark box 3 is dark box 3. At the same time as removing it to the outside, the plate material take-out device 6 and the plate material receiving shelf 8 are sequentially operated to feed only one plate material P in the dark box 3 to the exposure device B side. In this way, by removing the interleaving paper P'and carrying the plate material P alternately, the plate materials P of the same size can be sequentially supplied to the exposure device B.

On the other hand, when the size of the plate material P supplied to the exposure device B is changed during the plate making operation, for example, the newspaper 4 is used.
A plate P having a size of two pages to a plate P having a size of two pages of a newspaper
In the case of switching to, first, the plate material take-out device 6 and the lid temporary storage shelf 7 are used to close the dark box 3 containing the plate material P having a size of four pages of newspaper, and then the plate material take-out device 6 and the lid. The two small dark boxes 3 are opened by the temporary storage shelves 7, and the interleaving paper P ′ on the plate material P of the two opened small dark boxes 3 is simultaneously removed by the interleaving paper ejecting device 5 and the plate material ejecting device 6
The two plate materials P are simultaneously taken out by the
Then, the two plate materials P on the plate material receiving rack 8 are delivered to the exposure apparatus B side by the plate material delivery mechanism 14 at the same time.
At this time, the two plate materials P taken out from the inside of the two small dark boxes 3 are arranged in the plate material take-out device 6 so that a large gap is not formed between the two plate materials P fed to the exposure apparatus B side. The suction unit 9 is moved horizontally to reduce the gap between the plate materials P, and then the plate materials are placed on the plate material receiving shelf 8.

In the above embodiment, the three dark boxes 3 are arranged in parallel in the space surrounded by the light shielding cover 1. However, the number and size of the dark boxes 3 are the same as those in the above embodiment. The number and size are not limited to those described above, and may be any number and size. In this case, it goes without saying that the number of suction portions 9 of the plate material take-out device 6 corresponds to the number of dark boxes 3.
Further, in the above-described embodiment, among the three suction portions 9 of the plate material take-out device 6, two suction portions 9 located above the small dark box 3 are supported by the same lifting support mechanism 10. However, in another embodiment, the three suction portions 9 may be supported by separate lifting / lowering support mechanisms 10.
Further, in the above-described embodiment, the suction parts 9 of the plate material take-out device 6 are arranged above the respective dark boxes 3, but in other embodiments, the dark boxes 3 group. One suction part 9 is provided above the above so as to be horizontally movable and vertically movable,
You may make it open and close each dark box 3 and take out the plate material P with one suction part 9.

[0052]

As is clear from the above description, the plate feeding apparatus of the present invention can exhibit the following excellent effects. (1) In the plate feeding apparatus of the present invention, dark boxes in which unexposed plate materials are stored in a stacked manner are arranged in parallel, and an appropriate dark box is opened from each dark box to expose the unexposed plate material to the exposure device side. Therefore, when feeding plate material to the exposure apparatus like the conventional plate feeding apparatus described at the beginning, it is possible to move up and down all the heavy dark boxes stored in the stacking receiving frame. You don't have to. That is, the plate supply device of the present invention can supply the unexposed plate material in the dark box to the exposure device without lifting a heavy dark box or requiring large power. (2) Since the plate feeding device of the present invention is arranged such that the dark boxes in which the unexposed plate materials are housed in a stacked form are arranged in parallel, as compared with the conventional plate feeding device in which the dark boxes are stored in a stacked form. The height of the device itself can be reduced. (3) In the plate feeding device of the present invention, the dark boxes in which the unexposed plate materials are stored in a stacked manner are arranged in parallel, and a suitable dark box is opened from each dark box to store the plate materials stored inside. Since it can be supplied to the exposure device side, it is not necessary to replace the dark box with a dark box of another size when changing the size of the plate material during the plate making operation, and the plate material can be easily replaced and handled. You can do well. Further, several kinds of plate materials having different sizes can be stored, and the plate material having a desired size can be supplied to the exposure apparatus. However, since the number of plates to be stored is extremely large, it is not necessary to replenish plates frequently. (4) The plate feeding device of the present invention includes a plurality of dark boxes arranged in parallel, a plate material take-out device that opens and closes the dark boxes and takes out the plate material, and an interleaf paper take-out device that removes the interleaf paper. Since it is provided, the opening and closing of each dark box, the removal of interleaving paper, the switching of the dark box to be used, the transportation of the plate material to the exposure device, etc. can be automated, and the processing capacity can be improved. However, since opening and closing the dark box and taking out the plate material can be performed by the same plate material take-out device, it is not necessary to separately provide a device for opening and closing the dark box and a device for taking out the plate material, and the structure can be simplified. (5) In the plate feeding apparatus of the present invention, since the temporary lid placing rack and the plate material receiving shelf are configured to be horizontally movable, one lid temporary placing shelf and the plate material receiving shelf should be compatible with all dark boxes. Therefore, the structure can be simplified. However, since the temporary lid storage shelves and the plate material receiving shelves are formed in a grid pattern, the weight of each shelf can be reduced and the power for moving each shelf can be small. (6) Since the plate feeding apparatus of the present invention includes the plate material feeding mechanism for feeding the plate material received by the plate material receiving shelf to the plate material inlet of the exposure apparatus, the plate material inlet of the exposure apparatus is unnecessarily required. It is not necessary to increase the size, and the size of the plate material inlet of the exposure apparatus can be set to a size that allows the plate material to pass through. As a result, the shutter device provided between the plate supply device and the exposure device can be omitted.
