When the size of the PS plate 12 is larger than the ordinary one, the puncher 752 moves in the top-and-bottom direction of the PS plate 12, then interference between the PS plate 12 and the punchers 750 and 752 is prevented.

Description

[Detailed description of the invention]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plate printing apparatus for printing an image on a document film onto a photosensitive planographic printing plate (hereinafter referred to as "PS plate").

0002

[Prior art] PS used in rotary presses for newspaper printing, etc.
The plate is a negative film or an image of the negative film pasted on a transparent sheet is printed by a plate material printing device.

[0003] A stacker loaded with a plurality of PS plates is fed into the supply section of the printing plate printing apparatus by an auto feeder. After the PS plate is sent from the supply section onto the surface plate of the printing section, it is positioned at a predetermined position on the surface plate by a positioning device and held on the surface plate. The PS plate is movable in plane on the surface plate, and its relative position with the negative film or negative sheet can be changed.

On the other hand, a negative film or a negative sheet is inserted into a printing section from a negative film loading section (negative sheet loading section), aligned and placed at a predetermined position on a PS plate, and then brought into close contact with the printing section.

A predetermined amount of light is irradiated onto the PS plate on which the negative film or sheet is placed from a light source located in the printing section. As a result, the image recorded on the negative film is printed onto the PS plate.

[0006] There are two types of negative films or negative sheets that can be used: one for color printing and one for monochrome printing.
When loading a negative film or negative sheet, the operator operates an operation button on the operation panel to manually determine whether it is for color printing or monochrome printing. Such discrimination is based on the reasons shown below.

[0007] For color printing, multiple PSs are used for each color.
Since the plates are mounted on the rotary press and one image is printed, it is necessary to accurately position the plurality of PS plates on the rotary press. For this reason, when printing an image onto a PS plate, a circular hole and/or notch is provided at a predetermined position on the PS plate, the bending is performed using the circular hole and/or notch as a reference, and each Plate is bent using the notch as a reference.
I am trying to attach the S version to the rotary press. Note that in the case of monochrome printing, there is no need to provide a cutout because the printing is in a single color.

[0008] Since the notch is made by a puncher,
In order to decide whether or not to operate this puncher during image printing, the negative film or negative sheet is discriminated.

[0009] The puncher is arranged so as to provide notches on two sides corresponding to a direction perpendicular to the direction in which the PS plate is transported from the supply section. That is, the puncher has an insertion groove into which the end of the PS plate is inserted, and inserts the end of the PS plate by moving the PS plate placed on the surface plate in a direction perpendicular to the conveying direction. With the groove inserted, the punch blade is operated to create a notch.

0010

[Problem to be Solved by the Invention] However, although it is sufficient that the notch formation position by the puncher is always constant,
Depending on the type of rotary press to which the plate is installed, it may be necessary to change the notch position by several millimeters in the direction in which the plate is supplied. Conventionally, the relative position between the puncher and the PS plate cannot be changed, so
If a notch is required at a different position than the notch on the S plate,
This is done using a manual flat printer.

On the other hand, in the case of PS plates, sometimes a PS plate of a size larger than the normal size is subjected to a printing process. In such a case, since the relative position between the puncher and the PS plate is fixed, the edge of the PS plate may interfere with the puncher. The printing process for PS plates of different sizes is also performed using a manual flat printer.

[0012] As described above, although it is compatible with PS plate sizes and rotary presses that are usually frequently used, it cannot be compatible with sizes outside of these mainstream sizes, and the versatility of the equipment is limited. There is a problem of poor work efficiency.

The present invention takes the above facts into account, and provides a printing plate printing apparatus that improves the versatility of the apparatus, allows one unit to perform printing processing for several types of printing plates, and improves work efficiency. The purpose is to obtain.

[0082] A slope 12 is provided on the lower surface side of the guide piece 120.
0A is formed. This slope 120A is in contact with a slope 126A formed on the guide plate 126, and when the air cylinder 118 is actuated, the guide piece 1
20 rises while sliding on the slope 126A.

Furthermore, the drive shaft 118 of the air cylinder 118
A passes through another guide piece 123 so as to be freely inserted, and a protrusion 128 is provided on the lower surface side of this guide piece 123. One end of a tension coil spring 130 is fixed to the tip of this protrusion 128. The other end of the tension coil spring 130 is fixed to the tip of a pole 132 erected on the base 88. Therefore, the air cylinder 118 is biased clockwise in FIG. 13 around the shaft support.

Therefore, when the drive shaft 118A of the air cylinder 118 is extended, the rotary body 124 moves against the guide plate 1.
While being guided by the slope 126A of 26 and pressing the PS plate 12, it moves on the surface plate 22 to the position indicated by the two-dot chain line in FIG.
When the drive shaft 118A of the air cylinder 118 is retracted,
Since the drive shaft 118A is urged downward by the tension coil spring 130, it is guided by the slope 126A of the guide plate 126 and moved to the position shown by the solid line in FIG.

As shown in FIG. 14, in the second pusher 114B, an air cylinder 118B is arranged substantially horizontally, and a roller 119 is pivotally supported at the tip of the drive shaft 118C. When the drive shaft 118C is extended, the end face of the PS plate 12 is pressed through the roller 119 to abut against the reference pin 110 in the surface plate, thereby positioning the right side of the PS plate 12 for printing. Note that the portion of the PS plate 12 protruding from the surface plate 22 is supported by a guide plate 118D arranged at the same height as the surface plate 22.

Furthermore, the air cylinder 118B is connected to a compressed air supply device 278 via a solenoid valve 283, as shown in FIG. Compressed air is supplied to the air cylinder 118B by opening the solenoid valve 283. Solenoid valve 283 is connected to output port 274 of control device 264, as shown in FIG.

As shown in FIG. 32, punchers 750 are mounted on the bases 88 corresponding to the vertical directions of the surface plate 22, respectively.
, 752 are arranged. This pancha 750, 75
Reference numeral 2 is for forming a circular hole used when folding the exposed plate material and a rectangular notch that serves as a reference when positioning a plurality of PS plates at the same position in the case of color printing.

The puncher 750 is arranged at a position corresponding to the edge of the PS plate 12 when the PS plate 12 is positioned during top side exposure in the vertical direction, and the puncher 750 is positioned at a position corresponding to the edge of the PS plate 12 when the PS plate 12 is positioned during top side exposure in the vertical direction. It is arranged at a position corresponding to the end of the PS plate 12 when the PS plate 12 is opened.

The punchers 750 and 752 have different structures. First, when the right side of the PS plate 12 is positioned on the surface plate 22 by the reference pins 82, 84, 86, the punchers 750 and 752 have different structures. The puncher 750 corresponding to the end portion will be explained.

As shown in FIG. 33, the puncher body 754 of the puncher 750 is fixed on a base 88. The puncher body 754 has a rectangular block shape, and
A notch 756 is formed at the lower end of the surface facing the S plate 12. For this reason, the PS version 12 has the reference pin 82,
Once positioned by 84 and 86, the right end of the PS plate 12 is accommodated within the notch 756.

[0091] The mounting surface 88A of the base 88 on which the puncher 750 is mounted is located at a position slightly lower than the normal height position. On this mounting surface 88A, there is a surface plate 22.
A pair of widthwise guide rails 758 are attached parallel to each other along the widthwise direction of the frame. Width direction guide rail 75
A base 762 for movement in the width direction is placed on the base 8 via a support 760. The upper surface of the widthwise moving base 762 is at the same height as the normal surface of the guide plate 88A, and the right end of the PS plate 12 is placed on this widthwise moving base 762.

The widthwise moving base 762 is attached to the tip of the rod 765 of the air cylinder 763. The air cylinder 763 expands and contracts the rod 765 by driving a solenoid valve 767. The solenoid valve 767 is connected to the output port 274 of the control device 264 shown in FIG. Therefore, a signal from the control device 264 causes the solenoid valve 767 to
When actuated, the width direction movement base 762 is moved in the width direction of the surface plate 22 along the width direction guide rail 758. This movement allows punching to a predetermined punching position even if the punching position on the applied PS plate 12 is slightly different.

A through hole 764 is formed from the upper surface 754A of the puncher main body 754 to the notch 756. A punch blade 768 is slidably inserted into the through hole 764. Here, as the punch blade 768 descends along the through hole 764, a rectangular notch is formed at the end of the PS plate 12 accommodated in the notch 756.

The upper end of the punch blade 768 passes through the punch blade base 770. This punch blade base 770
is connected to the tip of the arm 772 via a shaft 774. A longitudinally intermediate portion of the arm 772 is accommodated between a pair of parallel vertical walls 776 formed on the upper part of the puncher body 754. The vertical wall 776 has a circular hole 7

Further, a circular hole (not shown) is formed in the arm 772 and is coaxial with the circular hole 778 when the arm 772 is accommodated between the vertical walls 776, and a shaft 780 is inserted therethrough. Therefore, the arm 772 is rotatable about the shaft 780, and when the arm 772 rotates counterclockwise in FIG. 33, the punch blade 768 is pushed down and a notch can be formed in the PS plate 12.

A connecting member 788 is attached to the base of the arm 772 via a shaft 782 to the tip of a rod 786 of an air cylinder 784. The air cylinder 784 is operated by the rod 786 by driving the solenoid valve 790.

When excited by a signal from the control device 264, the rod 786 is axially moved in the extending direction. Therefore, when the solenoid valve 790 is activated, the arm 772
is rotated counterclockwise about axis 778.

Next, the puncher 752 corresponding to the left end of the PS plate 12 when the right side of the PS plate 12 is positioned on the surface plate 22 by the reference pins 108, 110, 112 will be described.

As shown in FIG. 32, this puncher 75
2 has almost the same configuration as the puncher 750, but
A pair of arms 794 and 796 are provided on the puncher body 792. These arms 794, 796 are connected to each other by an air cylinder 798 operated by a solenoid valve 797, similar to the puncher 750.

A punch blade 804 having the same structure as the punch blade 768 is attached to the tip of one arm 794 via a punch blade base 802A, and is slidably inserted into the through hole 764. Further, a cylindrical punch blade 808 is attached to the tip of the other arm 796 via a punch blade base 802. This punch blade 808 is slidably inserted into a circular hole 806 formed in the puncher body 792 and penetrates into the notch 756 . Therefore, in addition to the rectangular notch, a circular hole is formed at the left end of the PS plate 12. This circular hole is used as a reference when bending the PS plate 12.

As shown in FIG. 34, this puncher 75
The mounting surface 88B of the base 88 on which the holder 2 is mounted is located at a position slightly lower than the normal height position. A pair of width-direction guide rails 812 that are parallel to each other are mounted on the mounting surface 88B along the width direction of the surface plate 22. The width direction guide rail 812 includes a width direction movement base 8.
14 is placed. An auxiliary base 818 for vertical movement is fixed to the widthwise movement base 814 via a vertical guide rail 816. The upper surface of the auxiliary base 818 for vertical movement is set at the same height as the normal surface of the base 88, and the left end of the PS plate 12 is placed on this auxiliary base 818 for vertical movement. Become.

The widthwise moving base 814 is attached to the tip of the rod 822 of the air cylinder 820. The air cylinder 820 expands and contracts the rod 822 by driving a solenoid valve 824. Solenoid valve 824 is connected to output port 274 of control device 264 shown in FIG. Therefore, a signal from the control device 264 causes the solenoid valve 824 to
When actuated, the width direction movement base 814 is moved in the width direction of the surface plate 22 along the width direction guide rail 812. This movement allows punching to a predetermined punching position even if the punching position on the applied PS plate 12 is slightly different.

A pair of vertical guide rails 816 are provided and are parallel to each other. Therefore, the auxiliary base 818 for vertical movement has a substantially L-shaped bracket 826.
It is attached to the tip of the rod 830 of the air cylinder 828 via the air cylinder 828. The air cylinder 828 expands and contracts the rod 830 by driving a solenoid valve 832. Solenoid valve 8
32 is the output port 27 of the control device 264 shown in FIG.
Connected to 4. Therefore, when the solenoid valve 832 is actuated by a signal from the control device 264, the auxiliary base 818 for vertical movement is moved in the vertical direction of the surface plate 22 along the vertical guide rail 816. This movement causes
Even if the applied PS plate is slightly larger than the normal size, interference between the PS plate 12 and the puncher 752 is prevented. <Plate Feeding Device> Also, as shown in FIG. 3, a PS plate feeding device 132 is arranged on the side of the surface plate 22. This PS plate feeding device 132 uses a pusher having the same configuration as the first and second pushers described above, and is shown in FIG.

Further, as shown in FIG. 3, a plate feed detector 318 is attached to the frame 11 for detecting the end of the PS plate 12 moved by the PS plate feeding device 132. This detector 318 is connected to the control device 264 and detects when plate feeding of the PS plate is completed. <Light Source> As shown in FIGS. 1, 15, and 16, a light source section 134 is arranged above the surface plate 22. Figure 1
5, in this light source section 134, a light source unit 500 on which a lamp or the like is installed forms a ceiling surface, and a box section 500A that projects upward is provided in the center of this light source unit 500. It is being

[0103] The lamp is housed within this box portion 500A. A cylindrical bracket 500C is attached to the side wall 500B of the box part 500A, and the exhaust unit 5
One end of a duct 504 constituting 02 is attached. The other end of the duct 504 is attached to the intake port of the fan 506.

[0104] The downwardly facing surface of the box portion 500A is open, and a reflective hood 508 is attached to correspond to this opening. The reflective hood 508 has a cylindrical shape with rectangular openings provided in both the upper and lower directions. The reflective hood 508 has a side wall 508A having an inclined surface that gradually widens downward. The back side of this inclined surface is a reflective mirror surface, which diffusely reflects the light rays from the lamp.

A transparent glass plate 510 serving as a heat-insulating glass plate is placed in the lower opening of the reflective hood 508, and is held between a frame member 512 serving as a mounting bracket. This frame member 512 is fixed to the reflective hood 508 with a plurality of screws 514, thereby holding the transparent glass plate 510.

[0106] With the above structure, the portion in which the lamp is housed is shaped like a closed box, and the air heated by the lamp is exhausted from the duct 504 of the exhaust unit 502. The operation of the exhaust unit 504 causes a certain amount of dirt and dust inside the reflective hood 508 to be sucked in.

[0107] Air cylinders 138 and 140 are provided on mutually opposing side wall portions 508A of the reflective hood 508, respectively.
is attached via a bracket 516. A rectangular frame-shaped light source hood 136 is supported in a suspended state at the tips of the drive shafts of the air cylinders 138 and 140.

Here, when the drive shafts of the air cylinders 138 and 140 are retracted, the light source hood 136
It is held at a position surrounding the reflective hood 508 (the position indicated by the solid line in FIG. 16).

These air cylinders 138, 140 are connected to a compressed air supply device 278 via electromagnetic valves 284, 286, as shown in FIG. Compressed air is supplied to the air cylinders 138 and 140 by opening these solenoid valves 284 and 286. Solenoid valve 284, 2

It is smoothly raised and lowered between the position indicated by the two-dot chain line. Around this light source hood 136, an upper detector 288 and a lower detector 290 are arranged at the upper and lower parts, respectively.

These detectors detect the upper and lower positions of the light source hood 136. These detectors are also connected to input port 272 of controller 264 as shown in FIG.

As shown in FIG. 16, the light source unit 5
A shutter 292 is arranged inside 00. This shutter 292 blocks the light from the light source section 134 or allows it to pass through, thereby blocking the light onto the surface plate 22.
Light is irradiated onto the surface plate 22. Further, an integrated light amount meter sensor 320 is arranged at the middle part of the inner wall of the light source hood 136. The light from the lamps of the light source unit 500 is made incident on the detection surface of the integrated light amount meter sensor 320. The integrated light amount meter sensor 320 converts the incident light amount into a pulse signal according to the amount of incident light, counts the pulse signal, and outputs it to the control device 264 when it reaches a set value. Thereby, the amount of light emitted by the lamp can be recognized.

A hard sponge 147 is attached to the lower end surface of the light source hood 136 via a substantially L-shaped bracket 146. This sponge 147 is the light source hood 1

An opening/closing board 518 is attached to the side frame body 11. This opening/closing board 518 is of a so-called double-opening type, and can be opened during maintenance inside the device.

[0115] A gap is created between the opening/closing board 518 and the table 520. This is to pull out the negative frame 194, and the cover sheet is attached and detached at the position shown by the solid line in FIG. During machine operation, this gap is closed by a shielding plate 522 for safety.

The shielding plate 522 has a rectangular flat plate shape, and both ends of the shielding plate 522 in the width direction are spanned between the frames 11 erected on the left and right sides of the back side of the opening/closing board 518.

[0117] Both ends in the width direction of the shielding plate 522 are connected to air cylinders 528 driven by electromagnetic valves 524, respectively.
It is supported by the frame 11 via the opening/closing board 508, and is normally held hidden behind the opening/closing board 508. Here, when the air cylinder 528 is driven, it protrudes downward from the lower end of the opening/closing board 518, and is configured to cover the gap. <Squeeze device> A squeeze device 148 is arranged between the surface plate 22 and the light source hood 136. This squeeze device 148 presses the negative sheet 24 on the PS plate 12 placed on the surface plate 22, and presses the negative sheet 24 and the PS plate 12.
This is to remove air between them and bring the PS plate 12 and negative sheet 24 into close contact.

As shown in FIGS. 17 and 18, the guide rails 150 are located on both sides of the surface plate 22 in the width direction (in the direction of the large arrow B in FIG. (However, Fig. 17, Fig. 1
8, the guide rail on one side was omitted). Slide blocks 152 are fitted into these guide rails 150, respectively, and are movable in the longitudinal direction of the guide rails 150, that is, in the longitudinal direction of the surface plate 22 (in the direction of the large arrow A in FIGS. 17 and 18 and in the opposite direction). It has become.

[0119] The intermediate portions of squeeze arms 154 are each pivotally supported on the slide block 152 by pins 155. A squeeze roller 156 is pivotally supported between the lower ends (one end) of these squeeze arms 154, and a guide roller 158 is pivotally supported at the upper end (other end) of each of these squeeze arms 154.

Further, one end of a pair of arms 162 is connected between the lower end of the squeeze arm 154 and the pin 155, respectively. The other end of these arms 162 is supported by a block 164 that is pivotally supported by the slide block 152. A compression coil spring 166 is disposed between the block 164 and the arm 162, and the tip of the arm 162 is pushed downward, that is, the squeeze arm 15
4 is constantly biased counterclockwise using the pin 155 as a fulcrum.

Further, a guide 160 is fixed to the frame body 11 corresponding to each guide roller 158, and a guide 160 is fixed to the frame body 11 in correspondence with each guide roller 158.
In the raised position, each guide roller 158 comes into contact with each guide 160, and the squeeze arm 154 is swung to the position shown by the solid line in FIG. 17 against the biasing force of the compression coil spring 166. Furthermore, squeeze arm 15
A stopper 157 is disposed corresponding to a portion between the upper end of 4 and the pin 155.

Therefore, when the motor 176 is rotated, the driving force of the motor 176 is transmitted to the sprocket wheel 174, the sprocket wheel 168 is rotated, and the belt 172 is conveyed. The conveyance of the belt 172 causes the slide block 152 to move in the length direction of the surface plate 22.

[0124] Squeeze device 14 configured as described above
8, when the holding frame 182 is in the raised position, the squeeze arm 154 is swung to the position shown by the solid line in FIG. 17 as described above. From this state, when the holding frame 182 is lowered onto the surface plate 22 together with the negative frame 194 (described later), the squeeze arm 154 moves around the pin 155 as shown in FIG. It is swung counterclockwise and comes into contact with the stopper 157 to stop the swiveling.

The swinging stop position of the squeeze arm 154 is shown by the dashed line in FIG. 17, and at this position the squeeze arm 154 is not pressing the negative sheet 24 against the PS plate 12. Therefore, negative film 36 and PS version 12
No excessive force is applied to the negative film 36 except when the two are brought into close contact with each other. After this, negative frame 194

The light beam irradiated from A is reflected at a predetermined distance and reaches the light receiving section 85.
The contact switches depending on whether or not light is received at 6B. Here, this rectangular hole 854 will be covered with a part of the negative sheet 24, but if the above-mentioned transparent sheet for color printing 25A is applied, the reflective tape 718 will correspond to this rectangular hole 854. It turns out. Therefore, the light beam emitted from the light projecting section 856A is reflected by the reflective tape 718 and reaches the light receiving section 856B. On the other hand, in the case of the transparent sheet 25B for monochrome printing, since the transparent portion covers the rectangular hole 854, the light beam emitted from the light projecting section 856A passes through the transparent sheet 25B as it is.

Therefore, the reflective photoelectric sensor 856 can determine whether the negative sheet 24 loaded in the negative frame 194 is for color printing or for monochrome printing.

This reflective photoelectric sensor 856 is connected to the input port 272 of the control device 264 shown in FIG.

As shown in FIG. 24(B), the pin bar 2
A pair of support pins 218 protrude from both sides of 10, respectively. These support pins 218 are inserted into elongated holes 220A of a pair of support blocks 220 fixed to the lower part of the negative frame 194, respectively. For this reason, pin bar 21

It is held rotatably around B.

[0147] Further, a shaft member 236A is supported between the pair of plates 240 by being sandwiched between these plates 240. This shaft member 236A includes an air cylinder 2
A connecting block 243 fixed to the tip of the drive shaft 42 is fitted onto the outside, and the pair of plates 240 and the drive shaft of the air cylinder 242 are swingably connected by a shaft member 236A. Air cylinder 242 is supported by negative frame 194. Furthermore, the air cylinder 242 is connected to a compressed air supply device 278 via a solenoid valve 298, as shown in FIG. Compressed air is supplied to the air cylinder 242 by opening the solenoid valve 298 .

[0148] Solenoid valve 298 is connected to output port 274 of control device 264, as shown in FIG.

As shown in FIG. 24(B), a holding member 244 is connected to the pin bar 210 by a hinge 246. One end of a pair of stoppers 248 is supported at the intermediate portion of this pressing member 244. This stopper 248
The other end is arranged to close the notch 232. This stopper 248 is located in the notch 23 of the pair of plates 240.
Extraction from within 2 is prevented. As a result, the pin bars 210 and 212 are operated by the air cylinder 242.
The negative sheet 24 supported by is pulled and tension is applied.

As shown in FIG. 20, the pin bar 212
A rectangular notch 224 and a V-shaped notch 226 are formed on the back side thereof.

[0151] These notches 224 and 226 are shown in FIG.
And as shown in FIG. 23, a cylindrical positioning cam follower 228, 2 attached to the side of the surface plate 22
30, and when the negative frame 194 moves in the longitudinal direction by the operation of the air cylinder 206, the notch 22
By inserting the cam follower 228 into the notch 226 and the cam follower 230 into the notch 226, the negative frame 194 comes into contact with the cam followers 228 and 230 at three points, allowing positioning in the length direction and width direction. (See Figure 23). In other words, the cam follower 228 contacts the bottom surface of the cutout 224 at one point, and the cam follower 230 contacts the bottom surface of the cutout 226 at two points, respectively.

In this way, the notches 224, 226, cam followers 228, 230, air cylinder 206, etc. constitute the negative sheet positioning device 23 shown in FIG.

Further, as shown in FIG. 24, the pressing member 244 of the pin bar 210 is rotated approximately 90 degrees after one end of the negative sheet 24 is supported by the pin bar 210, and held between the pin bar 210 and the negative sheet 24. The end of 24 is pressed down.

Further, as shown in FIGS. 22 and 25, negative frames 194 are arranged at both ends of the pin bar 212 side.
A pair of air cylinders 250 are arranged inside. These air cylinders 250 are connected to a compressed air supply device 278 via a solenoid valve 300, as shown in FIG. By opening this solenoid valve 300, compressed air is supplied to the air cylinder 250.

[0155] Solenoid valve 300 is connected to output port 274 of control device 264, as shown in FIG.

[0156] Between the drive shafts of these air cylinders 250, the ends of press rollers 252 arranged in the width direction are connected. Enlarged diameter portions are formed at predetermined intervals in the intermediate portion of this pressing roller 252, and are used to hold down a pressing member 256 connected by a hinge of the pin bar 212.

Further, as shown in FIG. 20, a pair of handles 253 are attached to one of the long sides of the negative frame 194, and are used when pulling out the negative frame 194 from the holding frame 182. be done. <PS plate ejection unit> A transport roller (not shown) is arranged in the PS plate ejection unit 20, and the PS plate with the image printed thereon is
The plate 12 is discharged to the outside of the plate printing device 10.

[0158] The frame body 11 is also equipped with a discharge detector 322 (Fig.
) are located. The ejection detector 322 is connected to the control device 264 to detect the state in which the PS plate 12 is ejected from the apparatus, and transmits the detected state to the control device 264. <Control Device> As shown in FIGS. 27 and 28, a display device 302 is connected to the output port 274 of the control device 264.

As shown in FIG. 28, this display device 302 includes a plate-making LED 304 that indicates that the process is in progress, that is, that the image is being printed onto the PS plate, and a plate-making LED 304 that indicates whether or not electricity is on. Power LED 306, emergency stop LED 308 indicating emergency stop, and trouble (failure within the device)
A trouble LED 310 is provided to indicate the trouble.

[0160] Furthermore, plate feeding, plate feeding carrier, positioning 1
, exposure 1, plate feeding, alignment 2, exposure 2, and plate discharge. These small LEDs 312 are arranged in the order in which the PS plates 12 are sent, and when the PS plates 12 are located at each processing step, they indicate that the PS plates 12 are present in that processing step.

[0161] Therefore, if a trouble occurs in the printing plate printing apparatus 10, it can be easily known that the trouble has occurred when the PS plate 12 has stopped.

Next, the operation of this embodiment will be explained. First, the negative frame 194 is pulled out from the holding frame 182, and the negative sheet 24 to which the negative film 36 has been pasted is attached to the pins 214A and 214 of the pin bar 210 and the pin bar 212.
C and pins 216A and 216B. From this state, the pressing members 244 and 256 are respectively brought down and pressed. From this state, the pair of air cylinders 250 are operated to move the press roller 252 from inside the negative frame 194 onto the press member 256. This ensures that one end of the negative sheet 24 is supported by the negative frame 194.

From this state, the air cylinder 242 is operated to pull the negative sheet 24 and apply tension. At this time, the pin bar 210 supporting one end of the negative sheet 24 is movable in the width direction of the negative sheet 24 and swingable around the shaft member 236A, so when applying tension to the negative sheet 24, No force such as twisting is applied, and the negative sheet 24 does not wrinkle.

After the negative sheet 24 is set in the negative frame 194, the negative frame 194 is pushed into the lower part of the holding frame 182.

On the other hand, as shown in FIG. 6, the tip of the plate feeding conveyor 40 is moved to the vicinity of the surface plate 22. here,
When a start button (not shown) is turned on, initialization is executed in step 398 shown in FIG. 29, and each process waits at its initial position.

At step 399, the flag F is set to 0, and the process moves to step 400, where the type of rotary press to be used and the size of the PS plate 12 are read. Usually, P
The S plate is of a fixed size, but if the rotary press used after plate making differs, the position of the notch used for positioning in color printing will differ in the width direction. Therefore, in this embodiment, it is necessary to move the punchers 750 and 752 in the width direction. Further, some PS plates 12 are large in size and may interfere with the puncher 752 arranged correspondingly to the normal size PS plate 12. Therefore, in this embodiment, it is necessary to move the puncher 752 in the vertical direction. Panchaya 750, 75 like this
2, the type of rotary press used and the size of the PS plate 12 are read.

[0167] In the next step 401, step 400
Puncher 7 based on the type of rotary press loaded in
50, 752 in the width direction. That is, the air cylinders 763 and 820 are driven to move the widthwise moving bases 762 and 8 along the widthwise guide rails 758 and 812.
Move 14. Here, in the puncher 752 on the left side, the auxiliary base 818 for moving in the vertical direction is moved in the width direction together with the base 814 for moving in the width direction, and the puncher 752 is moved in the width direction.
0,752 can be moved in the width direction with respect to the surface plate 22.

In the next step 402, the puncher 752 is moved in the vertical direction according to the size of the PS plate 12. That is, the air cylinder 828 is driven to move the auxiliary base 818 for vertical movement along the vertical guide rail 816 relative to the base 814 for widthwise movement. Thereby, the puncher 752 can be moved vertically with respect to the surface plate 22.

[0169] In the next step 404, plate feeding is started. This plate feeding is carried out by operating the auto feeder 9 and feeding the PS plate 1.
2 is sent out and inserted between the pair of conveyance rollers 65. The PS plate 12 sent out from between the pair of transport rollers 65 is guided onto the plate feeding conveyor 40 by guide rollers 68 and 70, is conveyed obliquely by the plate feeding conveyor 40, and is sent onto the surface plate 22. The detector 262 detects this and the control device 2
64.

[0170] In step 406, the control device 264 operates the display device 302 to turn on the plate feeding LED 312. This makes it possible to recognize that the PS version 12 is in the PS version supply section 14. At this time, if the leading end of the PS plate 12 is caught on the surface plate 22 and is not conveyed, the rear end of the PS plate 12 is pushed toward the surface plate 22 by the hooking member 74 by operating the air cylinder 72. This allows the PS plate 12 to be reliably conveyed onto the surface plate 22 (FIG. 7).

[0171] The PS plate 12 transported onto the surface plate 22 is moved to a predetermined position by a transport mechanism such as a suction cup (not shown).

[0172] In step 408, the PS plate 1 is placed on the surface plate 22.
2 is sent, the detector 262 detects this, and in step 410 the plate feeding carrier LED 312 is lit. This makes it possible to confirm that the PS plate 12 has been fed onto the surface plate 22.

At step 412, it is determined whether the printing position on the PS plate 12 is the first side or the second side.

In the case of the first side, alignment 1 is performed in step 414. That is, the air cylinder 92 of the first pusher 90A or 90C is activated by opening the solenoid valve 280. As a result, as shown in FIGS. 9 and 10, it is pressed and moved toward the reference pin 82 inside the surface plate and the reference pin 84 outside the surface plate, and comes into contact with these pins 82 and 84. At the same time, the air cylinder 118 of the second pusher 114A is activated by opening the solenoid valve 282. As a result, it is pressed and moved toward the reference pin 86 outside the surface plate, and comes into contact with this pin 86 . In this way P
The S plate 12 is positioned at a predetermined position on the surface plate 22 (the position indicated by the two-dot chain line in FIGS. 9 and 10). In this state, negative pressure is supplied to the suction groove 78C, and the PS plate 12 is moved to the surface plate 22.
fixed on top.

[0175] The state of alignment 1 is changed to step 416.
The alignment 1 LED of the display device 302 is turned on. This allows the operator to recognize to which position within the printing plate printing apparatus 10 the PS plate 12 is being sent and what processing is being performed thereon. The detector 324 detects the end of this positioning 1, and step 418 is executed.

Next, in step 418, it is determined whether or not the negative sheet 24 is being supplied. If the determination is positive, proceed to step 600; if the determination is negative, proceed to step 4.
After the following processing is performed in step 20, the process moves to step 418, and it is again determined whether or not the negative sheet 24 is being supplied.

[0177] In step 420, the surface plate 2 of the PS plate 12 is
2, the holding frame 182 and the negative frame 194 are lowered by the operation of the air cylinder 184 and placed on the ball casters 203 and 207.

From this state, the air cylinder 206 operates to move the negative frame 194 and fill the notches 224, 226.
Insert the cam followers 228, 230 inside. As a result, the negative frame 194 is positioned at a predetermined position on the surface plate 22. When the negative sheet 24 is positioned at a predetermined position on the PS plate 12, the squeeze device 148 is activated, and the negative sheet 24 and the PS plate 12 are brought into close contact with each other by the squeeze roller 156. When the squeeze roller 156 finishes squeezing, the squeeze roller 156 moves the negative sheet 24
Separate from above.

Next, negative pressure is supplied to the suction groove 78A, and P
The space between the S plate 12 and the negative sheet 24 is degassed, and the negative sheet 24 is suctioned and fixed to the surface plate 22.

In the next step 600, the reflective photoelectric sensor 856 determines whether the loaded negative sheet 24 is for color printing or monochrome printing. That is, the transparent sheet 15A for color printing is coated with reflective tape 718 in advance.
is pasted on the transparent sheet 15B for monochrome printing. When the negative sheet 24 is loaded into the negative frame 194, the light emitting part 856A of the reflective photoelectric sensor 856 passes through the rectangular hole 854 provided at one longitudinal end of the pin bar 212 (the end on the back side with respect to the device). If there is a reflective tape 718, the irradiated light beam
18 and reaches the light receiving section 856B. On the other hand, in the case of the transparent sheet 25B for monochrome printing, since the transparent part is placed over the rectangular hole 854, the light emitting part 8
The light rays emitted from 56A are directly transmitted to the transparent sheet 2.
It will pass through 5B. For this reason, the negative sheet 24
After loading the printer, you can determine whether it is for color printing or monochrome printing.

[0181] In the next step 602, if it is determined that the negative sheet 24 is for color printing, it is necessary to provide a notch in the PS plate 12, so the process moves to step 604 and the first side is printed with flag F set. or the second side, and
If it is determined that it is a surface (F=0), step 60
6, the puncher 750 is driven to form a notch at the right end of the PS plate 12 in FIG. Pancha 750
By driving the air cylinder 784, the arm 772 rotates in the counterclockwise direction in FIG. 33 about the shaft 778, and the punch blade 768 slides along the through hole 764. As a result, the punch blade comes into contact with the PS plate 12 housed in the notch 756, and a notch can be formed.

[0182] In step 602, it is determined that the second surface is
F=1), the process moves to step 608 and P
The puncher 752 is driven to provide a notch at the left end of the S plate 12 in FIG. The drive of the puncher 752 is the same as that of the puncher 750, but two arms 796 and 794 are provided at the left end, one of which has a rectangular punch blade 804 attached, and the other has a cylindrical punch blade 804. A punch blade 808 is attached, and at the same time a rectangular notch and a circular hole are provided. Note that the circular hole is used as a reference when bending the PS plate 12.

[0183] In the next step 421, the solenoid valve 524,
526 is energized to operate the air cylinders 528 and 530 to lower the shield plate 522, and then step 422
The air cylinders 138 and 140 are activated, the light source hood 136 is lowered, and the sponge 147 of the holding member 146 is activated.
contacts and presses the overlapping portion 145 between the negative sheet 24 and the edge portion of the PS plate 12. Thereby, the negative sheet 24 can be reliably brought into close contact with the PS plate 12, and blurring or the like will not occur.

[0184] When the lowering of the light source hood 136 is completed, the lower detector 2
90 is detected, the light from the light source section 134 is irradiated onto the PS plate 12 in step 424, and the image of the negative film 36 pasted on the negative sheet 24 is printed onto the PS plate 12. That is, in step 426, the display device 302 is activated to indicate that image exposure is to be performed.
Turn on D312. When the image exposure detector 320 detects this and the light is irradiated for a predetermined period of time, the shielding plate 522 is raised in step 427, and then the light source hood 136 is raised in step 428. When the upper detector 288 detects that the light source hood 136 has been raised, step 432 is executed.

At step 432, it is determined whether flag F is 1 or not. That is, in the case of printing on the second side, step 4
At step 34, the PS plate 12 is discharged from the surface plate 22, and the discharge detector 322 detects this discharge state, and at step 436, the display device 312 is activated and the discharge LED 312 is turned on.

If flag F is 0, it is determined again in step 412 whether or not it is the second side. In other words, if flag F is 0, it indicates that the first page is burned, so
Steps 438 and subsequent steps are executed.

[0187] In step 438, the PS plate feeding device 13
2 is activated to move the PS plate 12 on the surface plate, and as shown in FIG.
Or it is moved in the direction of the large arrow B in FIG. In step 440, the display device 302 is activated and the plate advance display LED lights up to indicate the state of plate advance. The plate feed detector 318 detects that the plate feed is completed, and step 442 is executed.

At step 442, alignment 2 is performed to align the PS plate 12 to a predetermined position on the surface plate 22. In step 444, the display device 302 is activated to indicate the state of alignment 2, and the alignment 2 LED lights up.

When alignment 2 is completed, alignment 2 detector 316 detects and executes step 446.

At step 446, flag F is set to 1. From this state, steps 418 and subsequent steps are executed to print the image recorded on the negative film 36 of the negative sheet 24 onto the PS plate 12.

[0191] At step 448, it is determined whether or not to continue processing the PS version 12. If the process is to be continued, steps 400 and subsequent steps are executed again. If processing is not continued, the process ends.
