2. Description of the Related Art A photosensitive lithographic printing plate (hereinafter referred to as "PS plate") mounted on a mounting table (hereinafter referred to as "skid")
Are placed in a layered manner with the photosensitive surface facing the lower layer and slightly inclined (about 15 °) with respect to the vertical.

The outermost PS plate on the skid has a punching hole for a breeding plate, which serves as a breeding plate reference position in the breeding machine, and a bending punch for determining a folding margin for hanging on a rotary press. It is necessary to form a punch hole for printing that serves as a hole and a printing reference position by the rotary press. At present, with some exceptions, the breeding punch hole and the bending punch hole are common, and the printing punch hole is abolished by using the end surface of the PS plate as a printing reference.

For punching the punch holes, an operator takes out the PS plate of the uppermost layer from the skid and carries it to a surface plate for punching the punch holes. After that, a punch hole is formed at a predetermined position with the end surface of the PS plate as a reference, and the PS plate is transported to the next process or another skid again.

As described above, since the punching work for punching holes is carried out by hand including transportation, it requires an excessive amount of labor and is poor in workability. Therefore, if the PS plate on the skid is transported by using a transport device, the labor of the transport work is reduced.

[0006]

However, the PS plate on the skid is placed vertically with an inclination of 15 °, and the PS plate on the surface plate is
Since the plate mounting surface is a horizontal surface or an inclined surface close to a horizontal surface, it is necessary to rotate the PS plate so as not to interfere with other devices and surface plates. Since the above-mentioned known transporting device is only for transporting, the work of placing it on a substantially horizontal surface plate after transportation to the vicinity of the surface plate becomes complicated, and the photosensitive surface of the PS plate may be damaged.

In consideration of the above facts, the present invention provides a photosensitive lithographic printing plate transfer device capable of reliably mounting a photosensitive lithographic printing plate taken out from a mounting table on a platen for punching holes. The purpose is to obtain.

According to the first aspect of the invention, the photosensitive lithographic printing plate is held upright by the holding means and transferred to the upstream side of the punch hole punching surface plate, and then rotated by the rotating means. Rotate so that the photosensitive surface of the plate faces upward. At this time, since the supporting means is in the retracted position and is retracted from the movement track of the photosensitive lithographic printing plate, the photosensitive lithographic printing plate and the supporting means do not interfere with each other during the rotating operation.

When the photosensitive lithographic printing plate is in a horizontal state, the photosensitive lithographic printing plate is positioned upstream of the platen for punching holes. Here, the photosensitive lithographic printing plate is transferred onto the supporting means by moving the supporting means to the supporting position. Then, the photosensitive lithographic printing plate can be placed on the surface plate by conveying the photosensitive lithographic printing plate in the direction of the surface plate by the conveying means.

According to the second aspect of the invention, the photosensitive lithographic printing plate which is leveled by the rotating means is horizontally slid by the sliding means from the upstream side of the surface plate by the sliding means, whereby the photosensitive lithographic printing plate is exposed. The lithographic printing plate can be placed horizontally on a surface plate.

According to the third aspect of the invention, the radius of gyration is expanded by sliding the photosensitive lithographic printing plate upward by the sliding means and then rotating it by the rotating means.
This allows the photosensitive lithographic printing plate to be in a horizontal state on the surface plate.

According to the fourth aspect of the present invention, the photosensitive lithographic printing plate which is parallel to the mounting surface of the punch hole punching surface plate by being rotated by the rotating means is used for punching the punch hole punches. When mounting on the mounting surface of the surface plate, the conveying device and the punch hole surface plate are relatively moved. This allows the photosensitive lithographic printing plate in the horizontal state to be opposed to the mounting surface of the platen for punching holes.

The adsorption positions of 0, 172, 194, and 220 are almost the same on the front and back surfaces of the PS plate 12 (the position where the PS plate 12 is sandwiched).
Therefore, there is no problem that the PS plate 12 is deformed by the suction force of these suction cups.

Here, when the PS plate 12 has a large size,
The lower part of the PS plate 12 is adsorbed by the preliminary suction cup 224.
This prevents the PS plate 12 from sagging in a horizontal state due to the rotating operation of the PS plate 12 described later.

74, 276, the positioning rollers 272,
It is confirmed that the positioning of the PS plate 12 has been completed by making 274 and 276 conductive.

When the positioning of the PS plate 12 is completed, the PS plate 1
A punch hole is punched by the puncher 294 or the puncher 296 at the leading end in the conveyance direction 2. This punch hole is used as a reference for printing by the plate breeding apparatus and as a reference for plate bending for loading into a rotary press.

When the PS plate 12 is punched, the suction on the fixed surface plate 244 side is released. Next, the servo motors 250 and 260 are driven, and the moving surface plate 246 is moved in the XY directions. Thereby, the PS plate 12 can be pulled out from the accommodating portion 300 of the punchers 294, 296, 298. Here, the air cylinder 332 of the discharge device 310 is driven, the suction cup support frame 334 is lowered, and the PS plate 12 is sucked by the suction cup 336. After the PS plate 12 is adsorbed, the suction plate support frame 334 moves up again, whereby the PS plate 12 is taken out of the surface plate 242. At this time, the PS plate 1 is moved by the moving surface plate 246.

The moving plate 404 is raised with respect to the base plate 402. At this time, since the suction cup support frame 218 is also moved together with the moving plate 404, the PS plate 12 rises while being sucked by the suction cup 220 (and / or the preliminary suction cup 225).

Here, when the air cylinder 214 is extended, the rotary frame 400 rotates, but since the rotary frame 400 has a substantially expanded outermost radius of rotation, the PS plate 12 swirls largely. Then, it is placed directly on the surface plate 242.

When the PS plate 12 becomes substantially horizontal,
When the suction by the suction cup 220 is released, the PS plate 12 is placed at a predetermined position on the surface plate 242.

The procedure for punching holes in the PS plate 12 placed on the surface plate 242, taking them out again by the discharge device 310, and passing them to the next step is the same as that in the first embodiment described above. Is omitted.

As described above, in the second embodiment, the rotating frame 400 has the double structure of the base plate 402 and the moving plate 404, and the moving plate 404 is rotated when the rotating frame 400 is rotated.
Since the rotation radius of the outermost circumference of the rotating frame 400 is increased by raising the PS plate 12, the PS plate 12 is directly attached to the surface plate 242.
It can be placed on the top, and the delivery process from the fixed transfer device 210 to the punch device 240 can be simplified.

[Third Embodiment] A third embodiment of the present invention will be described below with reference to FIG.

In the third embodiment, the same components as those in the first embodiment are designated by the same reference numerals, and the description of the configuration will be omitted.

The feature of the third embodiment is that the fixed transfer device 21 is used.
0 is used to receive the PS plate 12 from the moving transfer device 110 and place the PS plate 12 on the surface plate 242 of the punch device 240.

As shown in FIG. 21, the fixed transfer device 210.
The frame main body 211 is supported at its lower ends in the width direction by the sliding portions of the guide rails 227, respectively. For this reason, the frame main body 211 is moved along the guide rail 227 by the driving force of the driving means (not shown).
10 and the surface plate 242 can be moved in a direction toward and away from each other (direction of arrow S in FIG. 21).

The operation of the third embodiment will be described below. When the PS plate 12 is received from the moving transfer device 110, the frame body 211 is moved to the side closer to the moving transfer device 110. When the PS plate 12 is received, the frame body 211
Moves in a direction away from the moving transfer device 110 along the guide rail 227. Then, the PS plate 12 can be opposed to the surface plate 242 by laterally moving the support frame 216 by the driving force of the rodless cylinder 222.

Next, when the rod of the air cylinder 214 is extended, the suction cup support member 218 is rotated to the horizontal state. At this time, since the frame main body 211 is at the position most separated from the surface plate 242, there is no interference between the rotating PS plate 12 and the surface plate 242. In addition, the mobile transfer device 110
There is no interference with.

When the PS plate 12 is in the horizontal state, the frame body 211 is moved along the guide rails 227 to the surface plate 242.
Is moved in the direction of approaching the
Can be opposed to the surface plate 242.

The timings of the movement of the frame body 211 along the guide rails 227, the lateral movement of the support frame 216, and the rotation of the suction cup support frame 218 are not limited to the above, and the PS plate 12 is moved from the moving transfer device 110. After receiving, it is also possible to move the support frame 216 laterally while retracting the frame body 211.

Further, in the third embodiment, the frame body 2
11 can be moved along the guide rail 227,
The surface plate 242 may be moved toward or away from the frame body 211.

[Fourth Embodiment] The fourth embodiment of the present invention will be described below. The fourth embodiment is a modification of the second embodiment, and the essential components are functionally the same as those in the second embodiment, but there are some differences in shape and the like, and therefore, FIG.
2 and FIG. 23, the configuration will be described. The same components as those of the second embodiment will be described with the same reference numerals of the second embodiment.

The feature of the fourth embodiment is that the rotating frame 400 is rotated after the moving plate 404 is raised with respect to the base plate 402 in the second embodiment. After rotating the frame 400 to bring the PS plate 12 into a horizontal state, the moving plate 404 is moved (horizontally moved) with respect to the base plate 402 to move the PS plate 12 to the surface plate 242.
That is, they are made to face each other.

As shown in FIGS. 22 and 23, the rotary frame 400 is constructed by stacking a base plate 402 and a moving frame 403. The base plate 402 is attached to the support frame 216 by a pair of hinges 224, and is rotatable about the hinges 224 from a vertical position to a horizontal position by approximately 90 °. This rotation is performed by the air cylinder 214, as in the second embodiment.

The moving frame 403 includes a suction cup support frame 21.
8 is supported in parallel with the moving frame 403.

This sucker support frame 218 and the moving frame 4
A slide member 405 is interposed between the slide member 03 and the switch 03. The slide member 405 is fixed to the suction cup support frame 218 via a bracket 407 on the back side thereof,
The moving frame 403 is fixed to both ends in the width direction. The slide member 405 includes a pair of substantially C-shaped main bodies 40.
The openings 5A are opposed to each other and are connected via a slide block (not shown).

As a result, the moving frame 403 and the suction cup supporting frame 218 are relatively movable along the longitudinal direction of the main body 405A of the slide member 405.

The body of the rodless cylinder 410 is attached to the base plate 402, and its slider 410A is
It is attached to the back surface of the suction cup support frame 218. Therefore, by driving the rodless cylinder 410, the suction cup support frame 218 is moved along the longitudinal direction of the main body 405A of the slide member 405.

Here, the PS plate 1 is transferred from the moving transfer device 110.
This PS plate 12 is punched by the punching device 24 while receiving 2.
When laterally moved to a position corresponding to 0, the air cylinder 214 is driven to move the base plate 40 around the hinge 224.
After 2 is rotated (horizontal state), the moving frame 403 is horizontally moved by driving the rodless cylinder 410.

The fourth embodiment will be described below.
The PS plate 12 of the outermost layer is taken out from the skid 14 and conveyed by the moving transfer device 110, and the fixed transfer device 2
The process up to the transfer to the suction cup 220 of No. 10 is the same as that of the first embodiment, so the description will be omitted.

The PS plate 12 adsorbed by the suction cup 220 (and / or the preliminary suction cup 225) of the fixed transfer device 210 is driven by the rodless cylinder 222 as shown in FIG. 15 of the first embodiment. The lateral movement of 216 opposes the punch device 240.

Next, as shown in FIGS. 22 and 23,
When the air cylinder 214 is extended, the rotating frame 4
00 rotates, but in this state, the PS plate 12 does not reach the surface plate 242 and is held in a horizontal state.

When the PS plate 12 becomes substantially horizontal,
By driving the rodless cylinder 410,
The suction cup support frame 218 is horizontally moved with respect to the moving frame 403. Therefore, the PS plate 12 has a suction cup 220 (and / or
Alternatively, it moves horizontally while being attracted to the preliminary suction cup 225). When the suction by the suction cup 220 is released after the completion of the horizontal movement, the PS plate 12 is placed at a predetermined position on the surface plate 242.

The procedure for punching holes in the PS plate 12 placed on the surface plate 242, carrying them out again by the discharging device 310, and passing them to the next step is the same as in the first embodiment described above. Is omitted.

As described above, in the fourth embodiment, since the suction cup support frame 218 is horizontally moved after the rotation of the rotation frame 400, the PS plate 12 can be directly placed on the surface plate 242. From the fixed transfer device 210 to the punch device 24
The delivery process to 0 can be simplified.

As shown in FIG. 23, the surface plate 242
By attaching the synthetic resin columnar body 409 to the upstream corner, even if the PS plate 12 is bent from the vertical state to the horizontal state, it does not come into direct contact with the surface plate 242. , As guided by the cylindrical body 409, P
The back surface (lower surface) of the S plate 12 is not scratched.
