摘要： PROBLEM TO BE SOLVED: To provide a sheet-by-sheet suction method for sheet bodies, which can reduce the size and cost of a suction device by not only allowing stable suction of the uppermost layer sheet body accurately separated from the other lower layer sheet body, but also minimizing the suction area of a sucker and the capability of a negative pressure source as required, and a sheet-by-sheet suction device.
SOLUTION: Sheet-by-sheet suction is performed with the sucker controlled to be in the condition of a first minimum negative pressure P
1 required for sucking only one sheet of uppermost layer printing plate. Then, the feed of the printing plates is performed with the sucker controlled to be in the condition of a second negative pressure P
2 required for feeding the printing plates (a line Z). The degree of deformation of the printing plates, when sucked, into recessed shape along with the shape of the sucker is reduced, restricting the multiple suction of the number of printing plates. Thus, no need exists for great suction negative pressure P
x and for an increase in the suction area of the sucker or in the capability of a vacuum pump.

摘要： PROBLEM TO BE SOLVED: To provide a suction disk for a printing plate stably sucking and sending the printing plate together with a protective sheet, without getting wrinkles of the protective sheet in sucking and sending the protective sheet.
SOLUTION: A suction disk 40 comprises: a main body part 42 made of a rigid body; a skirt part 44 made of an elastic body; and a spring 50. If moment from the printing plate 12 acts on the suction disk 40 in sending the sheet, the spring 50 is elastically deformed, so that the main body part 42 is displaced (inclined) toward a direction of the moment acting on the suction disk 40 and actual load with respect to the suction disk is reduced, and thereby reducing the moment acting on the suction disk 40 (the moment is substantially absorbed). Since the spring 50 releasing the moment is structurally separated from the main body part 42 and the skirt part 44, the deformation of the suction disk is eliminated to prevent deformation and wrinkles of an interleaving paper sheet 13 along with the deformation of the suction disk 40.

摘要： PROBLEM TO BE SOLVED: To provide a suction and feed device for printing plates having reduced costs without complicating its construction while reliably sucking and feeding the printing plates without the need for calculating the proper arrangement of suckers and manual work for resetting of the suckers even when sucking and feeding the size different printing plates and changing the size of the printing plates in cassettes.
SOLUTION: The suction and feed device for the printing plates, a control device 54 actuates a motor 48 for a sucker moving mechanism 46 in accordance with size information for the printing plates 12 in the selected cassette 38 during sucking and feeding the printing plates 12 at a sheet feeding part 15 to move each sucker 40 to a predetermined sucking position where it is not placed at the cross edge of the printing plate 12. Thus, no air leakage occurs in the sucker 40 and the degradation of suction force is prevented, permitting stable suction and feed of the printing plates 12. No need exists for resetting each sucker 40 (changing a mounting position), greatly improving working efficiency.

摘要： PROBLEM TO BE SOLVED: To provide a suction pad for a printing plate capable of stably suction-adhering and sheet-feeding both a printing plate and a protective sheet simultaneously without causing wrinkling at the protective sheet during suction-adherence.
SOLUTION: This suction pad 40 is composed of a main body part 42 formed of a stiff body and a skirt part 44 formed of a resilient body. When sucking, a suction face 46 of the main body part 42 generates suction force by opposing to an interleaf sheet 13, and the skirt part 44 is resiliently elastically deformed along the interleaf sheet 13 and adheres closely to the interleaf sheet 13 to ensure airtightness. Since the main body part 42 is not deformed even if load when sucking is applied, the interleaf sheet 13 is not drawn and wrinkle does not occur. Consequently, air leakage does not occur between the interleaf sheet 13 and the printing plate 12 to suck both of the interleaf sheet 13 and the printing plate 12 stably and simultaneously for feeding.

摘要： PROBLEM TO BE SOLVED: To provide a sucking and sending device for a sheet body surely sending an uppermost-layer sheet body from a lower-layer sheet body and stably separating the uppermost-layer sheet, when the uppermost layer sheet body out of a stacked plurality of sheet bodies is sucked and sent.
SOLUTION: In the sucking and sending device 50, a vacuum pump 52 generates pulsating negative pressure for making suction disks 40 suck a printing plate, and a solenoid two way valve 58 and a variable throttle valve 64 can release suction negative pressure into the air within a range where the suction disks 40 can suck the printing plate. By releasing the suction negative pressure into the air, differences occur in suction force among the suction disks 40 caused by differences in levels of the pulsating negative pressure, the suction disks 40 are vertically deformed along with the pulsations. Therefore, the uppermost-layer printing plate 12 sucked by the suction disks 40 is vertically vibrated (operation of division), is surely separated from the lower-layer printing plate, and then is stably sent.

摘要： PROBLEM TO BE SOLVED: To provide a sucking and sending device for a sheet body surely separating an uppermost-layer sheet body from a lower-layer sheet body and stably separating the uppermost layer sheet body, when the uppermost-layer sheet body out of a stacked plurality of sheet bodies is sucked and sent.
SOLUTION: In the sucking and sending device 50, actuators 60 are independently and separately connected to each of a plurality of suction disks 40. When a printing plate 12 is sucked and lifted to a predetermined level, every other actuator 60 out of actuators 60 is operated at the same time and suction disks 40 connected to the operated actuators 60 are displaced upward. Therefore, the sucked uppermost-layer printing plate 12 is bent to be in a corrugated shape, air flows between the uppermost layer printing plate 12 and the next lower-layer printing plate 12 to separate (divide) the uppermost-layer printing plate 12 from the lower-printing plates 12, and only the uppermost-layer printing plate 12 is stably sent.

摘要： PROBLEM TO BE SOLVED: To highly accurately carry plural kinds of sheets different in at least in a width directional dimension with one side reference. SOLUTION: Roller pairs 3 for sandwiching and carrying a storage phosphor sheet 40 with the one side reference in a reference position 5, are composed of a driving roller 1 and a nip roller 2. The nip roller 2 is composed of a hollow intermediate shaft 21 and rubber roller parts 22A, 22B and 22C. The intermediate shaft 21 is rotatably supported by a central shaft 23 having a reference position 5 side outer diameter formed larger than an outer diameter on the opposite side of the reference position 5. Both end parts of the central shaft 23 are energized to the driving roller 1 side by compression springs 27a and 27b. Spring force of the compression spring 27b is set larger than spring force of the compression spring 27a. Thus, the sheet 40 is equally sandwiched and carried by the driving roller 1 and the nip roller 2 regardless of the size of the sheet 40.

摘要： PROBLEM TO BE SOLVED: To surely prevent scanning unevenness due to a lateral slide of a belt member from occuring, when a sheet body is subscanned and conveyed. SOLUTION: The belt member 84 is made to cyclically travel as shown by an arrow F by a motor 78 and then an accumulative phosphor sheet S is conveyed via 1st and 2nd conveyor roller couples 54 and 56 as shown by arrow X2. After the belt member 84 has been previously moved by prescribed length through the motor 78 as shown by arrow E prior to scanning, the accumulative phosphor sheet S is subscanned and conveyed by the 1st and 2nd conveyor roller couples 54 and 56 through the rotating operation of the belt member 84, as indicated by an arrow X1. Consequently, the belt member 84 is arranged stably at a desired position about the peripheral surface of a driven pulley 74 during scanning and the belt member 84 will not slide laterally, so that the accumulative phosphor sheet S can be subscanned and conveyed with high precision.
