Definitions

  • the invention relates to a rotary sheet-fed printing press for perfecting with a reversing drum between printing cylinders of double-large diameter two successive printing units according to the preamble of claim 1.
  • Such a rotary sheet printing machine is known from JP-SHO 3-12517.
  • the sheet is then gripped on its leading edge by clamping grippers which are movably arranged on the printing cylinder and controlled in the work cycle of the machine, and is pulled along the entire length at the transfer point at which the sheet is transferred to the reversing drum, with pliers grippers movably arranged on the reversing drum grasp its trailing edge, so that the sheet is now led with its trailing edge ahead around the turning drum.
  • the register-based sheet transfer represents a very difficult problem because it would require smoothing of the sheet on the printing cylinder that functions as a storage drum. With known devices, however, this cannot be achieved because of the necessary means for setting the format on the printing cylinder.
  • the invention is based on the object of achieving a register-oriented sheet transfer from the printing cylinder acting as a storage drum of the front printing unit in the direction of sheet travel to the turning drum when the sheet is turned in a rotary sheet-fed printing machine for perfecting with a reversing drum between double-sized printing cylinders of two successive printing units .
  • the suction nozzles provided according to the invention provide greater security in the sheet detection at its rear edge the pliers grippers of the turning drum reached because the suction cups in the turning drum always bring the trailing edge of the sheet into a precise position in which they are gripped by the pliers grippers of the turning drum.
  • known rotary suction cups with suction opening asymmetrical to the axis of rotation are suitable, as are described for example in DE 24 52 096.
  • known arrangements are also suitable, for example in accordance with DE 30 36 790.
  • the rotary suction cups arranged in the turning drum in the vicinity of the pliers grippers can be arranged transversely to the machine center with a spacing next to one another and an angle of rotation that increases from the machine center outwards for smoothing the sheet.
  • the blanket cylinders 1 and 2 of two successive printing units have a simply large nominal diameter.
  • the printing cylinders 3 and 4 interacting with the blanket cylinders 1 and 2, on the other hand, are equipped with twice the nominal diameter.
  • a reversing drum 5 with a double-large diameter is also arranged.
  • the sheets 6 to be printed are picked up in a sheet feeder 7 one after the other by the clamping gripper system 8 of the front printing cylinder 3 in the direction of sheet travel, transported through the printing nip of the front printing unit in the direction of sheet travel and fed to the second printing unit via the reversing drum used as face-up printing.
  • the sheet 6 to be printed is turned by the turning drum and fed with its trailing edge to the second printing unit.
  • the turning drum 5 has suction nozzles 10 arranged in the vicinity of its gripper system 9, which suck the sheet 6 guided past the transfer point at the transfer point on its rear edge against the circumference of the turning drum 5 and thereby execute a movement transversely to the longitudinal direction of the machine, so that it passes through on its front edge the gripper system 8 of the printing cylinder 3 of the sheet 6 held in the direction of the sheet running in front runs smoothly over its entire length against the circumference of the printing cylinder 3 and, at the moment of transfer, assumes a precisely defined position with its trailing edge in which the gripper system 9 of the turning drum 5 detects the trailing edge of the sheet .
  • the transfer point is defined by the straight connecting line 11 of the axes of rotation of the printing cylinder 3 and the turning drum 5.
  • FIG 3 it is shown schematically that the suction nozzles 10 can be arranged next to one another at a distance transversely to the longitudinal center of the machine, the asymmetrically arranged suction openings 13 in the suction phase executing a rotational movement with an angle of rotation which increases from the longitudinal center of the machine to the outside, thereby thereby reducing the lateral Achieve arch tightening next to arch tightening in the circumferential direction.
