Abstract

Die Erfindung betrifft einen Transportzylinder zum Transportieren von Bögen in einer Druck- oder Lackiermaschine umfassend wenigstens eine Greifervorrichtung zum Greifen und Festhalten der Vorderkante eines zu transportierenden Bogens, die in wenigstens einer Ausnehmung des Transportzylinders angeordnet ist und mit dem Transportzylinder um dessen Rotationsachse rotiert, wobei im/am Transportzylinder (1) ein Antrieb vorgesehen ist, mittels dem die Greifer (36) der wenigstens einen Greifervorrichtung (3, 30-38, 40) über einen vorgegebenen/vorgebbaren Drehwinkelbereich des Transportzylinders (1) tangential zur Mantelfläche des Transportzylinders (1) bewegbar sind. Die Erfindung betrifft weiterhin ein Verfahren zum Transportieren von Bögen in einer Druck- oder Lackiermaschine bei dem mit wenigstens einer Greifervorrichtung die Vorderkante eines zu transportierenden Bogens gegriffen und festgehalten wird, wobei die Greifervorrichtung in wenigstens einer Ausnehmung eines Transportzylinders angeordnet ist und mit dem Transportzylinder um dessen Rotationsachse rotiert, bei dem die Greifer (36) und deren zugeordnete Greiferauflage (38) der wenigstens einen Greifervorrichtung (3, 30-38, 40) durch einen im/am Transportzylinder (1) vorgesehenen Antrieb über einen vorgegebenen/vorgebbaren Drehwinkelbereich des Transportzylinders (1) tangential zur Mantelfläche des Transportzylinders (1) bewegt werden.

The invention relates to a transport cylinder for transporting sheets in a printing or coating machine comprising at least one gripper device for gripping and holding the leading edge of a sheet to be transported, which is arranged in at least one recess of the transport cylinder and rotates with the transport cylinder about its axis of rotation, wherein / on the transport cylinder (1) a drive is provided, by means of which the grippers (36) of the at least one gripper device (3, 30-38, 40) over a predetermined / predefinable rotation angle range of the transport cylinder (1) tangentially to the lateral surface of the transport cylinder (1) are movable. The invention further relates to a method for transporting sheets in a printing or coating machine in which at least one gripper device, the leading edge of a sheet to be transported is gripped and held, wherein the gripper device is arranged in at least one recess of a transport cylinder and with the transport cylinder to the Rotates rotation axis in which the gripper (36) and its associated gripper pad (38) of at least one gripper device (3, 30-38, 40) by a in / on the transport cylinder (1) provided drive over a predetermined / predetermined rotation angle range of the transport cylinder ( 1) are moved tangentially to the lateral surface of the transport cylinder (1).
