Abstract

PURPOSE:To obtain a sheet material peeling method by which a sheet material is smoothly peeled from a surface plate without being damaged by lighting contact force between the sheet material and the surface plate. CONSTITUTION:Plural circular grooves 402 are formed on the placing surface of the surface plate 400 for a PS plate 12, and the contact area between the surface plate 400 and the back surface of the PS plate 12 placed on the surface plate 400 is decreased. Namely, the PS plate 12 does not reach a specified position immediately after it is fed from a fixed shifting device, and allowed to slide on the surface plate 400 by pushers 404 and 406 so as to be positioned at the specified position. In the case the contact area between the surface plate 400 and the PS plate 12 is large at the time of sliding, sliding ability is deteriorated, for example, because of effect by static electricity. Therefore, the contact area is decreased by the circular groove 402, the sliding ability is prevented from being deteriorated by the static electricity. Furthermore, resistance force in the case of separating (peeling) the PS plate 12 from the surface plate 400 is lightened.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention positions a sheet material on a surface plate by a conveying device, performs a predetermined processing, and sends the sheet material to the next step after the processing is completed. The present invention relates to a sheet material peeling method for peeling a sheet material.

[0002]

2. Description of the Related Art An image is printed on a sheet material, for example, a photosensitive lithographic printing plate (hereinafter referred to as "PS plate") by a stencil machine, developed, and then printed on a rotary press.

In this case, the PS plates are placed one by one on a punch table (plate) by hand, and the plates are used for winding around the punch holes for the plate and the rotary press, which serve as a positioning reference for printing by the plate. A punch hole serving as a reference for a plate bending position for bending is formed.

By the way, when the PS plate is positioned on the punch table, a groove is provided on the surface plate so as not to cause a deviation when punching holes, and the groove is set to a negative pressure so that PS
Holds the plate by suction. PS with punched holes completed
After releasing the negative pressure state of the groove, the plate is sucked by a suction cup and lifted to be conveyed to the next step.

[0005]

However, when the PS plate is sucked and lifted by the suction cup after punching holes, the PS plate is
The plate may come into close contact with the surface plate, and the lifting force may act. This is because the base of the PS plate is made of an aluminum plate, the surface treatment is anodizing (alumite) treatment, and the platen is also made of metal (aluminum). It is possible that static electricity is generated (charge is charged) during sliding (lateral movement for positioning after mounting) and negative pressure release of the groove is unsatisfactory. In order to determine the main cause of these two factors, an experiment was conducted in which the negative pressure of the groove is reversely applied when the negative pressure is released. As a result, since there is no great effect, it can be determined that adhesion due to static electricity is the main cause.

If the PS plate is forcibly peeled from the surface plate, the film surface (image recording surface) will be damaged.
The suction force of the suction cup cannot be increased.

In consideration of the above facts, the present invention provides a sheet material peeling method that alleviates the adhesive force between the sheet material and the surface plate and allows the sheet material to be smoothly separated from the surface plate without damaging the sheet material. Is the purpose.

[0008]

According to a first aspect of the present invention, a sheet material is positioned on a surface plate by a conveying device, a predetermined processing is performed, and after the processing is finished, the sheet material is sent to a next step. At this time, a sheet material peeling method for peeling a sheet material from the surface plate, characterized in that the contact area between the sheet material and the surface plate is reduced when the sheet material is positioned on the surface plate. There is.

The invention according to claim 2 is characterized in that a plurality of concave portions are provided on the sheet material mounting surface of the surface plate to reduce a contact area between the sheet material and the surface plate.

According to a third aspect of the present invention, when the sheet material is a photosensitive lithographic printing plate, the contact area ratio with the surface plate with respect to the surface area of the photosensitive lithographic printing plate is 70% or less. Is characterized by.

[0011]

According to the invention described in claim 1, when the sheet material is placed on a surface plate and a predetermined processing (for example, processing for punching a hole in the sheet material) is performed, the sheet material is Precise positioning and flatness must be maintained. This allows the sheet material to be processed with high accuracy.

After the above processing, the sheet material is conveyed to the next step. However, if the sheet material is in close contact with the surface plate, the sheet material cannot be smoothly separated from the surface plate.
Therefore, the contact area between the surface plate and the sheet material is reduced to the extent that the flatness is not impaired. As a result, the resistance at the time of peeling can be mitigated, and problems such as forcibly peeling and damaging the sheet material can be avoided.

According to the second aspect of the present invention, in order to reduce the contact area, a plurality of concave portions are provided on the sheet material mounting surface of the surface plate. This reduces the contact area between the surface plate and the sheet material by the sum of the opening areas of the recesses,
The peeling resistance can be relaxed.

According to the third aspect of the present invention, when the sheet material is a photosensitive lithographic printing plate, if the contact area ratio with the surface plate to the surface area of the photosensitive lithographic printing plate is 70% or less, The resistance at the time of peeling can be relaxed to the maximum without impairing the flatness.

When the rodless cylinder 508 is driven, the drive block 508A moves, so that the base 502 moves along the guide rail 506. Further, when the horizontally moving sub-cylinder 510 is driven while the rodless cylinder 508 is not driven, the base 50 is moved.
2 will be moved a little horizontally, but in this case,
The drive block 508A and the base 502 are designed to move relative to each other.

The horizontal movement amount by the horizontal movement sub-cylinder 510 is determined by the accommodating portion 300 of the punchers 294 and 296.
Is determined according to the depth dimension of
Since the depth is about 20 mm, the drive rod 508A and the base 502 are relatively moved with a slightly larger movement amount (about 25 mm). As a result, the vertical movement path of the PS plate 12 and the puncher 2
94 and 296 will not be interfered with each other.

A drive shaft 516 is provided at the center of the base 502.
An air cylinder 516 having A projecting downward is fixed, and a drive shaft 516A penetrates the base 502 and is fixed to a suction cup support frame 518 arranged below and parallel to the base 502. In addition, the air cylinder 51
6, a plurality of guide rods 520 whose axial direction is parallel to the drive shaft 516A of the air cylinder 516,
It is slidably arranged on the base 502 via a slide bearing 522. The upper ends of the guide rods 520 are fixed to the rectangular top plate 524, respectively. A rectangular hole 524A is formed in the center of the top plate 524,
The structure does not interfere with the air cylinder 516.

The lower end of the guide rod 520 is fixed to the sucker support frame 518, and the air cylinder 5
16 is driven to sucker support frame 518 and top plate 5.
Both 24 are raised and lowered in a horizontal state. Suction cups 526 and 527 are attached to the suction cup support frame 518, and these suction cups 526 are connected to a negative pressure supply means (not shown), and the PS plate on the surface plate 400 is supplied with the negative pressure. 12 is adsorbed.
The suction cup 527 is attached via a bracket 529 to a position separated from the suction cup support frame 518, and sucks the vicinity of the punched portion of the punch hole. The suction cup 527 has an outer diameter smaller than that of the suction cup 526 directly attached to the suction cup support frame 518.

Further, as shown in FIG. 31A, in the vicinity of the suction cup 527, an air jet nozzle 531 is provided.
Is provided, and the ejection port thereof is directed to the suction direction of the PS plate 12. From the nozzle 531, guide pins 602 on the pallet 600 described later (see FIG. 31B).
When it is inserted into the punch hole, air is blown out.

As shown in FIGS. 28 and 32, the base 502 has the body of the lifting sub-cylinder 528 fixed to the upper end of the base 502 corresponding to the guide rods 520 at the four corners. The drive shaft 5 of this lifting sub-cylinder 528
28A is projected upward, and the tip thereof is fixed to a bracket 532 which is stretched over a pair of moving frames 530 supporting the base 502.

When the lifting sub-cylinder 528 is driven, the driving shaft 528A is slightly expanded and contracted. The amount of expansion and contraction corresponds to the gap size of the accommodating portion 300 of the punchers 294 and 296.
The amount of expansion and contraction (for example, about 4 mm) is smaller than the gap size of 00 (about 7 mm).

That is, in the suction cups 526 and 527 of the suction cup support frame 518, the lifting sub-cylinder 528 is shown in FIG.
In the state of 2 (B), the PS plate 12 is brought into close contact with the PS plate 12, and a part of the PS plate 12 placed on the surface plate 242 is accommodated in the accommodating portion 300, and is driven when adsorbing and lifting ( FIG. 32 (A) (state), which allows the PS plate 12
Is held (lifted) from the surface plate 400 and held without interference with the punchers 294 and 296.

Then, the horizontally moving sub-cylinder 510 is used.
The PS plate 12 is completely removed from the accommodating portion 300 of the punchers 294, 296 by driving
Interference between the movement locus of the S plate 12 and the punchers 294 and 296 when it is moved up and down is eliminated.

Therefore, the PS plate 12 can be discharged from the surface plate 400 onto the pallet 600 in the subsequent process by raising the suction cup support frame 518 by the air cylinder 516 and horizontally moving it by the rodless cylinder 508. It will be possible.

As shown in FIGS. 31A and 31B,
A guide pin 602 is projected on the pallet 600. As for the guide pin 602, the PS plate 12 has a suction cup 52.
6 and 527 are sucked and moved horizontally, and pallet 600
When it is placed on the PS plate 12, the PS plate 12 is arranged at a position corresponding to the punched hole. Therefore, when the PS plate 12 is placed on the pallet 600, the guide pins 602 are inserted into the punch holes, so that the placement position of the PS plate 12 on the pallet 600 is always constant.

Here, the guide pin 602 has an outer diameter L
Is 5.8 mm, which is slightly smaller than the opening diameter M (6 mm) of the punched holes formed in the PS plate 12 for easy insertion, and the air jet from the nozzle 531 In the PS plate 12, the punch hole is pressed in the direction in which it is inserted into the guide pin 602, and the insertability is further enhanced.

Next, the operation of the automatic punching device 10 according to this embodiment will be described. After loading the skid 14 having the PS plate 12 of a predetermined size and type into each loading port of the skid loading unit 16, the PS plate 12 of a desired size and type is loaded by the transfer device 110.
It is taken out from the skid 14 and delivered to the fixed transfer device 210.

The movement of the movement transfer device 110 will be described below (see the flowchart of FIG. 33).

When the power switch (not shown) is turned on to start the operation, the flag G is confirmed (step 90
0), if the flag G is not set, the reference position (original position) is set. In order to pulse-control the drive of the servo motor 114, it is necessary to determine the reference position. This reference position is provided with an original position near the end of the rail 100 opposite to the fixed transfer device 210, apart from the position where the skids 14 are arranged, and corresponds to each skid 14 by the number of pulses from this original position. It is moved to the position where you want to.

At the original position, the proximity sensor 201 is provided, the moving transfer device 110 moves toward the original position (step 902), and the detected piece 208 provided on the moving transfer device 110 side. By blocking this, the preliminary position of the moving transfer device 110 is detected (step 904).
Here, the drive of the servo motor 114 is not immediately stopped, but the drive is continued.

That is, if control is performed so that the driving of the servo motor 114 is stopped when the preliminary position is detected,
Due to machine difference (deviation of proximity sensor, deviation of detected piece 208), an error corresponding to one rotation of the drive shaft of the servo motor 114 may occur. Therefore, the drive of the servo motor 114 is stopped and the original position is set at the time when the pulse output every one rotation of the drive shaft of the servo motor 114 is detected among the output pulses accompanying the drive of the servo motor 114 (step 90
6) The flag G is set (step 908). The flag G is reset when the operation of the device is finished (for example, when the power is turned off) or when the device is reset.

In this way, the displacement at the time of positioning the moving transfer device 110 can always be positioned at a constant position as long as the machine difference is within the range of one rotation of the drive shaft of the servo motor 114.

Here, the movement range of the movement transfer device 110 is determined by the instructed number of pulses because the servo motor 114 is pulse-controlled, but may overrun due to some factor. For example, as a mechanical factor, a shift in meshing of the teeth of the rack gear 108, a relative shift between the servo motor drive shaft and the pinion gear 116, and the like can be considered.

Therefore, in this embodiment, the movement of the movement transfer device 110 is controlled by pulse control, and limit switches 201 and 202 for confirmation are provided near both ends of the movement range (outside the normal movement range). Limit switch 2
The mobile transfer device 110 is detected at 01 and 202 (step 9
10, 912), the servo motor 114 is forced
Is stopped (step 912). This prevents the mobile transfer device 110 from significantly overrun. Further, since the shock absorber 203 is used together with the limit switches 201 and 202, the shock can be softened when the moving transfer device is forcibly stopped.

As described above, the movable transfer device 110 positioned at the original position is moved to the position corresponding to the predetermined skid 14 in accordance with the instruction by the pulse number thereafter. Also,
In this original position, since the skid 14 does not exist, a maintenance work space can be relatively ensured even when the arm unit such as the suction cup support frame 160 is extended to the maximum extent.

Further, in the moving transfer device 110, the servo motor 114 and the suction cups 168, 170, 172, 19 are provided.
Electrical wiring such as a solenoid valve, air piping, and the like, which are arranged between the negative pressure supply means 2 and the negative pressure supply means, are also provided, and these also move, but in this embodiment, a cable bear 189 or the like is used. Therefore, for example, even if the wiring is frequently deformed, its strength is sufficient and there is no problem such as disconnection.

Next, when the size and type of the PS plate 12 are selected and input to the control panel 50 (step 916),
From the skids 14 loaded in the skid loading section 16, the skid 14 on which the PS plate 12 is placed according to the selection is searched (step 918), and the mobile transfer device 110 is moved to the rail based on the search result. Begin moving along 100 (step 920).

The servo motor 114 is driven based on the number of pulses corresponding to the retrieved skid 14, and when the servo motor 114 reaches a predetermined position, the drive of the servo motor 114 is stopped.
Along with this, a proximity sensor 206 is provided at a position corresponding to each skid 14, and the presence or absence of the moving transfer device 110 can be confirmed by blocking the detected piece 208 (step 922).

That is, the servo motor 11 is controlled by pulse control.
The position corresponding to each skid 14 can be confirmed by controlling the drive and stop of No. 4 and the proximity sensor 206, and the positional deviation by pulse control (that is, feedforward control) can be confirmed by other means. . Therefore, before a serious problem such as interference with the skid 14 due to the subsequent extension of the arm 140 occurs,
Errors can be suppressed to a minimum. If an error occurs, error processing is performed (step 924). This error processing may be performed, for example, by returning the movable transfer device 110 to the original position and then moving it from the original position again. If this does not stop at the predetermined position even after repeating this several times, the manual operation is performed. You may make it position-align by.

The moving transfer device 110 moves on the rail 100 by the drive of the servo motor 114, and the desired PS
When the plate 12 is stopped at a predetermined position of the loading port 44, the moving transfer device 110 starts the suction operation of the PS plate 12 (step 926).

When the PS plate 12 of a desired size is taken out from the skid 14 by the suction operation, the moving transfer device 110
Moves toward the standby position on the fixed transfer device 210 side (step 928). At this time, the mobile transfer device 110
Is decelerated when it reaches the vicinity of the standby position, and the proximity sensor 20
5 detects the detected piece 208 (step 930),
It stops at a predetermined position (standby position) in the same manner as it stops at the original position (step 932). In this way
Mobile transfer device 110 that moved the PS plate 12 to the standby position
Performs the process of delivering the PS plate 12 to the fixed transfer device 210 (step 934).

Here, it is confirmed by the flag F whether or not the stop switch 90 of the operation switch panel 89 is operated (step 936). If the flag F is set, the process proceeds to step 938 and temporarily. Perform stop processing. The suspension will be described later.

Next, the PS plate take-out process will be described (see FIG. 3).
(See the flowchart of 4). The movable transfer device 110 stopped at a predetermined position is contracted and arranged in the original position on the front surface of the support base 134 and the support frame 1 and the support frame 1.
50 is extended by driving the rodless cylinders 142 and 148 (step 1000). At this time, since the rodless cylinders 142 and 148 operate simultaneously so as to extend the support frame 150 in the same direction, the suction cup support frame 160 arranged on the support frame 150 is mounted on the skid 14 in a short time. It can be made to face the surface of the PS plate 12 present. In addition, the support frame 150
Can be accommodated in a compact state even if the difference between the extended state and the contracted state is large because the arm 140 expands and contracts in two stages via the arm 140.

By making the suction cup support frame 160 attached to the support frame 150 face the surface of the PS plate 12, the suction cups 168, 170, 172, 192 attached to the suction cup support frame 160 are moved to the P position on the skid 14.
It can be arranged corresponding to the S plate 12.

Next, the suction cup supporting frame 160 is moved from the vertical position by 15 by driving the air cylinder 156.
Tilt (step 1002), PS on skid 14
The plate 12 is parallel to the surface of the plate 12. In this state, the air cylinders 180, 182, 184 are driven to suck the suction cups 168,
170 and 172 are projected and the air cylinder 5
After driving 1, 52, 53 to project the block 55 (step 1004), the suction cup support frame 160 is moved to P
It approaches toward the S plate 12 (step 1006). When the suction cup support frame 160 is brought close to the surface of the PS plate 12, the servo motor 114 of the moving transfer device 110 is used.
At the same time, the servomotor 130 is driven to approach while descending, so that the suction cup support frame 160 faces a certain position of the PS plate 12.

In this way, the suction cup support frame 160
When the skid 14 approaches the PS plate 12 of the skid 14, the block 55 of any of the air cylinders 51, 52, and 53 comes into contact with the surface of the PS plate 12 or the back plate 22. As a result, it is confirmed whether or not the remaining amount of the PS plate 12 on the skid 14 is equal to or more than a predetermined amount (about 50 sheets in this embodiment) (step 1).
008, 1010, 1012, 1014).

That is, when a predetermined number or more of PS plates 12 are stacked on the skid 14, the P stacked plates are stacked.
Since the thickness of the S plate 12 is larger than the difference X in the protrusion amount of the block 55 between the air cylinder 51 and the air cylinder 53, the blocks 55 of the air cylinders 51 and 52 first come into contact with the outermost PS plate 12 and are driven. The shaft 54 contracts and an internal switch (not shown) operates. This makes it possible to detect that the remaining amount of the PS plate 12 mounted on the skid 14 is not insufficient.

Further, the remaining amount of the PS plates 12 mounted on the skid 14 is insufficient, and the thickness of the stacked PS plates 12 is smaller than the difference X in the protrusion amount of the blocks 55 of the air cylinder 51 and the air cylinder 53. In this case, when the suction cup support frame 160 approaches the back plate 22 of the skid 14, the block 55 of the air cylinder 53 first comes into contact with the back plate 22 of the skid 14, and the drive shaft 54 of the air cylinder 53 contracts. Thereby, the air cylinders 51, 52
The sensor of the air cylinder 53 operates before the sensor of 1. As a result, the remaining amount of the PS plate 12 mounted on the skid 14 is less than or equal to a predetermined amount (about 50 in this embodiment).
It is possible to detect that the PS plate 12 is insufficient, and output that the remaining amount of the PS plate 12 is insufficient (step 101).
6). As a result, the yellow light 88 of the signal tower 84 provided corresponding to each of the loading ports 44 blinks, and it can be confirmed that the remaining amount of the PS plate 12 mounted on the skid 14 is insufficient. It is like this.

Further, when the blocks 55 of the air cylinders 51 and 52 do not contact the surface of the PS plate 12 at substantially the same time, the PS plate 1 is kept in a predetermined state with the suction cup support frame 160.
When it is determined that the PS plate 12 is not opposed to the second plate, the work for taking out the PS plate 12 is stopped (step 1018).

As described above, in this embodiment, by using the air cylinders 51, 52, 53 of the same standard, the mounting positions are changed and the remaining amount of the PS plate 12 mounted on the skid 14 is equal to or more than a predetermined amount. Since it is detected whether there is a shortage, it is extremely easy to set and confirm the detection range.

Block 55 of air cylinders 51 and 52
Contact the surface of the PS plate 12 at substantially the same time and determine that the suction cup support frame 160 faces the surface of the PS plate 12 in a predetermined state, a negative pressure is supplied to the suction cups 168, 170, 172 to supply PS. Start adsorption of the plate 12 (step 10)
20). At the same time, the air cylinders 51, 52, 5
The drive shaft 54 of No. 3 is contracted. After that, when it is confirmed that the suction plates 168, 170, 172 have adsorbed the PS plate 12 by a vacuum switch (not shown) (step 102).
2) The air cylinder 186 is operated to cause the suction cup 192 to protrude, and the PS plate 12 is adsorbed by the suction cup 192 (step 1024). At this time, when the plate detection sensor 200 detects the PS plate 12 (step 1026),
A single-wafer process is performed in which only the outermost PS plate 12 is adsorbed and taken out (step 1030). When the plate detection sensor 200 does not detect the PS plate 12, it is determined that there is no PS plate 12 on the skid 14. And suckers 168, 170, 1
The negative pressure supply to 72 and 192 is released, and the taking out of the PS plate 12 is stopped (step 1028).

In the moving transfer device 110, the suction of the PS plate 12 of the outermost layer is started while confirming the remaining amount of the PS plate 12 mounted on the skid 14 in this way.

As shown in FIGS. 11 (A) to 11 (C), the upper suction cups 168, 172, 174 have different strokes.
The plate 12 elastically deforms into a mountain shape. The elastic deformation of the PS plate 12 is caused between the suction cup 168 and the suction cups 170 on both sides of the suction cup 168.
Two chevron shapes can be formed, and a gap is formed between each of the chevron-shaped portions and the PS plate 12 of the next layer, and air is supplied from the air nozzle 196 to this gap. As a result, air enters between the outermost PS plate 12 and the next PS plate 12, and the suction cup 16 of the suction cup support frame 160 is sucked.
PS plate 12 adsorbed by 8, 170, 172, 192
It is possible to release the close contact state between the PS plate 12 of the next layer.

In this way, the suction cups 168, 170, 1
With the PS plate 12 adsorbed by the 72, 192, the air cylinders 180, 182, 184, 186 are contracted and the suction cup support frame 160 is skided.
By separating from the skid 14, only the outermost PS plate 12 can be reliably taken out from the skid 14.

The suction cup support frame 160, which has taken out the PS plate 12 of the outermost layer from the skid 14, is in its original position (vertical state).
And the air cylinders 142 and 148 are driven to return the arm 140 and the support frame 150 to the original position (step 1032). This makes rail 100
The suction cup support frame 160, which has largely protruded from the skid loading section 16 side, is returned to the rail 100 in a state where the PS plate 12 is adsorbed and held.

By the way, around the skid loading section 16,
The rope posts 85 and the signal towers 84 are arranged so that the rope 86 is stretched around to prevent entry into the moving range of the moving transfer device 110, thereby ensuring safety within the moving range of the moving transfer device 110. If the rope 86 is detached and the rope is to be inserted into the skid loading section 16, the mobile transfer device 110 is designed to be in an emergency stop. The skid 1 loaded in the loading port 44 of the skid loading section 16
4 is replaced, the stop switch 90 of the operation switch board 89 is operated to stop the mobile transfer device 110 at the original position or the standby position.

Next, the temporary suspension of the mobile transfer device 110 will be described (see the flowcharts of FIGS. 37 and 38).

In the interrupt routine shown in FIG. 37, it is confirmed whether or not the stop switch 90 of the operation switch board 89 has been operated (step 940). When the stop switch 90 is operated, the operation state of the moving transfer device 110 is confirmed (step 942), and the operation for adsorbing the PS plate 12 is performed, or when the PS plate 12 is adsorbed. Is set to the flag F (step 944). If the PS plate 12 is not in the suction operation, the moving / transferring device 110 is moved to the standby position or the original position (step 946), and the temporary stop process is performed (step 938).

The flowchart of FIG. 38 shows a temporary stop state of the moving transfer device 110.

In this paused state, the first step 9
At 50, the power and air (including negative pressure) to the mobile transfer device 110 are shut off to bring about the same state as an emergency stop, and a melody phon not shown is sounded to stop the mobile transfer device 110. Notification (step 9)
52). At this time, the stop display of the operation switch panel 89, etc. 9
2 lights up.

In this way, the mobile transfer device 110 is set to P
In a state where the S plate 12 is not adsorbed, the power supply and the air supply are shut off in a state where the S plate 12 is moved to the original position on the control panel 50 side or the standby position on the fixed transfer device 210 side, and the transfer device 11 is moved.
After confirming the stop of 0 by the stop indicator lamp 92 of the operation switch panel 89 or the melody horn,
By removing the rope 86 of 4, the skid 14 can be replaced. Here, in a state where the rope 86 is removed from the signal tower 84 or the rope post 85, the transfer device 110 is not activated.

The skid 14 is replaced to move and transfer device 11
When activating 0, the rope 86 is hung on the signal tower 84 (confirmed in step 954), and then the activation switch 91 of the operation switch panel 89 is operated (step 9).
Confirm with 56). As a result, power and air can be supplied to the moving transfer device 110 (step 958),
In the next step 960, the flag F is reset. As a result, the mobile transfer device 110 can start from the work next to the work completed before the stop.

When the moving transfer device 110 is stopped, the moving transfer device 110 is stopped at the original position or the standby position at the end of the rail 100 while the PS plate 12 is not adsorbed. It is easy to restart the mobile transfer device 110.

For example, if the mobile transfer device 110 is the PS plate 12
If it is stopped while sucking and holding the PS plate 12, the supply of air (negative pressure) is cut off, so that the PS plate 12 cannot be sucked and held.
Will fall on the floor, for example. In addition, the suction cup support frame 160 may stop in a protruding state.
It is not easy to restart the mobile transfer device 110 from such a state and to continue the processing before the stop, and the suction cup support frame 160 is used by the skid loading unit 1.
When stopped in a state of protruding toward the 6 side, the skid 14
Will hinder the replacement work.

On the other hand, in the present embodiment, the moving transfer device 110 sucks the PS plate 12 before or after the PS plate 12 is sucked.
Since the S plate 12 is transferred to the fixed transfer device 210 and stopped at the time when the work of one cycle is completed, it is extremely easy to shift to the next work when restarted. Further, since the position where the mobile transfer device 110 is stopped can be a position where the skid 14 is not loaded in the vicinity, for example, even when performing maintenance of the mobile transfer device 110, a relatively large work space is provided. Can be secured. Further, even when the skid 14 is exchanged at the loading port 44, the moving transfer device 110 does not interfere with the skid 14 exchange work.

Next, according to the flow chart of FIG. 35, the PS plate 1 from the mobile transfer device 110 to the fixed transfer device 210 will be described.
The second delivery procedure (based on step 980 in FIG. 33) will be described.

First, in step 1100, the rodless cylinder 222 is driven to drive the fixed transfer device 210.
Are moved to the side corresponding to the rail 104.

The fixed transfer device 210 includes the suction cup 16
A suction cup 220 is provided so as to face a part of each of 8, 170, 172, and 192.
In step 1, the moving base 112 is moved with the suction of the suction cup 220 and the preliminary suction cup 225 started (step 1104). As a result, the suction cup 220 becomes the PS plate 12
Contact with the photosensitive surface of. At this time, the mobile transfer device 110
Is moving at a slow speed, and is stopped when the suction by the suction cup 220 is confirmed (for example, detected by the vacuum switch) (steps 1106 and 1107). Here, the suction cup on the side of the moving transfer device 110 is not opposed to the suction cup 225 on the side of the fixed transfer device 210.
Only the hanging PS plate 12 faces 25. For this reason, if the PS plate 12 is curled, the PS plate 12 may not be adsorbed by the preliminary suction cup 225. However, in this embodiment, the air nozzle 197 is provided below the moving transfer device 110 side, and P
By ejecting air from the air nozzle 197 when the S plate 12 is delivered (step 1108),
Since the PS plate 12 is pressed by the wind pressure toward the fixed transfer device 210, even if the PS plate 12 has a curl tendency, the PS plate 12 can be smoothly brought into close contact with the preliminary suction cup 225, and the preliminary suction cup 225 can be surely attached. Thus, the PS plate 12 can be adsorbed. This prevents the PS plate 12 from sagging in a horizontal state due to the rotating operation of the PS plate 12 described later.

In the next step 1110, the suction cups 220,
It is determined whether or not suction has been confirmed in all of the used suction cups of the preliminary suction cups 225, and if a negative determination is made, step 1
The process moves to 112, and processing such as abnormal stop is performed. If an affirmative decision is made in step 1110, the operation moves to step 1114 and the following processing is performed. That is, the discharge of air from the air nozzle 197 is stopped, and the back surface side of the PS plate 12 is sucked while the photosensitive surface of the PS plate 12 is sucked by the suction cup 220 and the preliminary suction cup 225 of the fixed transfer device 210 side. Mobile transfer device 1
The suction of the suction cups 168, 170, 172, 192 of 10 is released. As a result, the PS plate 12 is transferred to the moving transfer device 1
10 can be transferred to the fixed transfer device 210.

In this case, the suction cups 168, 17 of each other are
The suction positions of 0, 172, 192, and 220 are almost the same position on the front and back surfaces of the PS plate 12 (the position where the PS plate 12 is held).
Therefore, there is no problem that the PS plate 12 is deformed by the suction force of these suction cups.

The PS plate 12 adsorbed by the suction cup 220 (and / or the preliminary suction cup 225) on the fixed transfer device 210 side is driven by the rodless cylinder 222 to support frame 2.
The horizontal movement of 16 causes it to face the punch device 240 (step 1116).

Next, as shown in FIG. 18, when the air cylinder 214 is extended, the rotating frame 228 rotates, but in this state, the PS plate 12 does not reach the surface plate 400 and is in a horizontal state. Held in.

When the PS plate 12 becomes substantially horizontal,
By driving the rodless cylinder 238,
The suction cup support frame 218 is horizontally moved with respect to the moving frame 232. 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 this horizontal movement, the PS plate 12 is placed at a predetermined position on the surface plate 400.

As described above, since the suction cup support frame 218 is horizontally moved after the rotation of the rotation frame 228, P
The S plate 12 can be placed directly on the surface plate 400, and the delivery process from the fixed transfer device 210 to the punch device 240 can be simplified.

Incidentally, as shown in FIG.
By attaching the synthetic resin columnar body 408 to the upstream side corner portion, even if the PS plate 12 is bent when it is rotated from the vertical state to the horizontal state, it does not come into direct contact with the surface plate 400. , As guided by the cylindrical body 408, P
The back surface (lower surface) of the S plate 12 is not scratched.

When the PS plate 12 is placed on the surface plate 400, the punchers 298 and 304 in the PS plate width direction are pulled in from the surface plate 400. Also, the pusher 404,
Both 406 are in the retracted state.

Therefore, the large-sized PS plate 12 has the surface plate 4
Even when placed on 00, this puncher 304,
There is no interference with the positioning roller 444 and the pushers 404 and 406.

Next, according to the flow chart of FIG. 36, P
The positioning procedure of the S plate 12 on the surface plate 400 will be described.

When the PS plate 12 is placed at a predetermined position on the surface plate 400, the motor 421 is driven to move the pusher 404 to a position corresponding to the PS plate 12 on which the pusher 404 is mounted (step 1200), and the pusher 404. , 406 is
By driving the air cylinder 282, the air cylinder 282 is moved in the direction perpendicular to the axis (step 1202) and the PS plate 12 is pressed.

The side of the pressed PS plate 12 opposite to the side pressed by the pushers 404 and 406 is brought into contact with the positioning roller 444. This positioning roller 444 is used for the punchers 294, 304 (puncher 30
4 is integrally formed with the PS plate 12 only on the back side in the transport direction), so that the punchers 294, 296, 298, 3
Accurate positioning can be performed without causing the relative position of the punching hole 04 to the punching position to change. Further, since the presence or absence of the PS plate 12 is also confirmed by the sensor 425 (step 1204), there is no possibility that a post-process work (perforation work) is erroneously performed in the absence of the PS plate 12.

When the PS plate 12 is placed on the surface plate 400, they come into close contact with each other, and the pushers 404, 4
When pressed by 06, a large resistance force may be generated. It is considered that one of the factors is that the static electricity charged on the surface plate 400 or the PS plate 12 attracts each other.

Therefore, in this embodiment, a plurality of circular grooves 402 are provided on the surface plate 400 so that the PS plate 12 and the surface plate 400 can contact each other without impairing the flatness of the PS plate 12 on the surface plate 400. Since the area is reduced, the force of attracting each other is reduced, and P by the pushers 404 and 406 is reduced.
The S plate 12 can be pressed smoothly.

In this embodiment, the surface plate 400 is provided with a plurality of circular grooves 402, but the present invention is not limited to this. For example, circular holes may be used as long as the contact area can be reduced. .

When the positioning of the PS plate 12 is completed (affirmative determination in step 1204), the groove provided in the surface plate 400 is set to a negative pressure (step 1206).
Hold 2 in close contact. This completes the positioning of the PS plate 12.

In this holding state, a punch hole is punched by the puncher 294 or the puncher 296 at the leading end of the PS plate 12 in the carrying direction (step 1208). 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.

Here, the punch scraps pass through the through holes of the fixed blade 436 and are guided below the surface plate 400, and the shooter 4
46, 448 through the waste box 450, 452, 454
Housed in. This waste box 450, 452, 454
Has a side surface (a side surface on the side where the punchers 298 and 304 are disposed) that is perpendicular to the PS plate conveying direction of the surface plate 400 as an outlet, and a pair of waste receiving boxes 452 on the back side of the PS plate conveying direction. 454, connected in series (hook 456
In this state, the punch scraps from the two punchers are respectively handled in a state of being connected to each other. Therefore, by grasping and pulling the grip 452A of the scrap collecting box 452 on the front side, the scrap collecting box on the back side is held. 454 can also be pulled out. As a result, scrapping work can be performed from one side surface of the surface plate 400, and workability is improved. Further, since the waste receiving boxes 452, 454 are divided into two, this drawing work space can be small.

When the PS plate 12 is punched, the punchers 298 and 304 are retracted and the surface plate 400 is removed.
The suction of the PS plate 12 is released, and the base 502 of the discharging device 500 is moved on the surface plate 400. At this time, the cylinder 534 is driven and the drive shaft 534A is moved to the cylindrical portion 536.
Guide to and house. This allows the base 502 to be accurately positioned.

Next, the air cylinder 516 is driven,
The suction cup support frame 518 is lowered, and the PS plate 12 is sucked by the suction cup 526. After the PS plate 12 is sucked, the lifting sub-cylinder 528 is driven to raise the suction cup support frame 518 by a slight amount (about 4 mm). That is, since the PS plate 12 after punching holes is partially accommodated in the accommodating portion 300 of the punchers 294 and 296, the PS plate 12 cannot be greatly raised as it is. Therefore, the PS sub-plate 12 is raised by the elevating sub-cylinder 528 to such an extent that it does not interfere with the surroundings of the accommodating portion 300.
Disengage from.

At this time, as described above, the surface plate 400 is provided with the plurality of circular grooves 402 to reduce the contact area between the PS plate 12 and the surface plate 400, so that the attraction force to each other is reduced, and the suction cup 526. Therefore, the PS plate 12 does not have a function of being forcibly separated from the surface plate 400, and deformation or damage does not occur.

Next, when the horizontally moving sub-cylinder 510 is driven, the driving rod 50 of the rodless cylinder 508 is driven.
8A and the base 502 move relative to each other, the base 502 moves horizontally a little (about 25 mm), and the PS is moved from the accommodating section 300.
The plate 12 can be removed.

After that, the air cylinder 516 is driven to raise the suction cup support frame 518 significantly, so that the PS plate 12 can be smoothly lifted upward without any interference with the punchers 294 and 296.

Next, after the drive shaft 534A of the cylinder 534 is disengaged from the cylindrical portion 536, the rodless cylinder 5
When driving 08, the driving rod 508A is moved,
The PS plate 12 can be conveyed to the next step. In this case, the drive rod 508A and the base 502 are moved integrally.

When the PS plate 12 reaches the delivery position for the next process, the cylinder 534 is driven again to drive the drive shaft 534A.
To stretch. Since the cylindrical portion 536 is also provided at this delivery position, the drive shaft 534A is guided and housed in the cylindrical portion 536 and positioned at a predetermined position.

Next, the drive shaft 51 of the air cylinder 516.
By extending 6A and releasing the suction by the suction cups 526 and 527, the PS plate 12 can be easily placed on the pallet 600 for delivery to the next step.

At the time of this placement, the suction cup 527 and this suction cup 5
The punch holes provided in the PS plate 12 are moved to the pallet 600 by releasing the suction cup 526 opposite to the suction plate 27 first.
The guide pin 602 is inserted into the punch hole because it corresponds (substantially coaxially) with the guide pin 602 provided on the. In this case, since the outer diameter of the guide pin 602 is slightly smaller than the opening diameter of the punch hole, the insertion is facilitated.
Further, since air is ejected from the nozzle 531 during this insertion, the PS plate 12 is pressed in the direction in which it is inserted into the guide pin 602, and the insertability is further improved. afterwards,
The PS plate 12 is placed at a predetermined position on the pallet 600 by releasing the suction of the PS plate 12 by the other suction cups 526.

In this way, the PS plate 12 is transferred to the pallet 600.
Since it is inserted into the punch hole of the guide pin 602 when the sheet is placed, the position of the PS plate 12 on the pallet 600 is always constant, and the subsequent steps (for example, plate-making machine)
Can be smoothly transported to.

In this embodiment, PS is used as the sheet material.
Although an example in which the plate (photosensitive lithographic printing plate) 12 is applied has been described, the sheet material to which the present invention is applied is not limited to the PS plate. For example, it can be applied to a sheet material suction device for taking out other photosensitive materials and sheet materials such as paper one by one from the outermost layer.

As described above, the sheet material peeling method according to the present invention alleviates the adhesive force between the sheet material and the surface plate so that the sheet material can be smoothly separated from the surface plate without damaging the sheet material. It has an excellent effect.
