Handling device of a printing press
View Patent ↗A handling device of a printing press, in particular for handling printing plates during an automated change of printing plates on a printing unit of a printing press, is disclosed. The handling device has a manipulator arm, where a manipulator head is allocated to one end of the manipulator arm, which head features a handling element, in particular a holding element for printing plates. The manipulator arm is of a multi-piece design of several segments, where a swivel axis is included on each end of each segment, around which axis at least the respective segment can be swiveled, and where a separate drive for providing the respective swivel motion is allocated to each swivel axis.
1. A handling device of a printing press for handling a printing plate, comprising:
a manipulator arm, including:
a first segment including a first set of parallel braces;
a second segment including a second set of parallel braces; and
a third segment including a third set of parallel braces;
a first swivel axis coupled to adjacent ends of the first set of parallel braces and the second set of parallel braces;
a second swivel axis coupled to adjacent ends of the second set of parallel braces and the third set of parallel braces;
a first drive coupled to the first swivel axis, wherein the first swivel axis is moveable by the first drive;
a second drive coupled to the second swivel axis, wherein the second swivel axis is moveable by the second drive;
wherein the first segment and the second segment are moveable relative to each other by movement of the first swivel axis;
and wherein the second segment and the third segment are moveable relative to each other by movement of the second swivel axis; and
a manipulator head coupled to the third segment, wherein the manipulator head includes a handling element engageable with the printing plate.
2. The handling device according to claim 1 , wherein the handling element is embodied as a suction device including suction nozzles for handling printing plates, wherein there are two suction nozzles for each printing plate handled, the suction nozzles being positioned in a floating manner on a common support element in such a way that, when grasping and transporting a printing plate, a fixing device blocks the floating positioning of the respective suction nozzles and, when delivering a printing plate, the fixing device releases the floating positioning of the respective suction nozzles.
3. The handling device according to claim 1 , wherein an end of the first segment that connects the manipulator arm to a frame and/or to a wall is stationary with respect to the frame and/or the wall.
