Cooperating ones of these frame parts are placed against each other along a common joining surface, in a first operational position. These frame parts are separated from each other in a second operational position. An interstice, that is partly defined by these frame parts, is formed between the separated frame parts in the printing unit. At least one of the cooperating frame parts is supported so that it is movable along an adjustment path. At least one sensor is provided and is usable to monitor the interstice. The sensor has orientation characteristics or a sensory range along the joining surface. A control unit is provided and is connected to the at least one sensor. At least one drive unit is assigned to at least one of the cooperating frame parts and is usable to change the frame parts from one operational procedure into the other operational procedure. A control element is arranged in a control system and is usable to supply power to the first drive unit that is controlled by the control unit in accordance with a signal which is supplied by the sensor that is monitoring the interstice. The control element is also able to activate the first drive unit and is controllable independently from the activation of the first drive unit. A functional position of the control element blocks a relative movement between the frame parts with that functional position being selected by the control unit. | 07-07-2011 |
20110197776 | PRINTING UNIT OF A PRINTING PRESS, COMPRISING AT LEAST TWO FRAME PARTS, THE POSITION OF WHICH RELATIVE TO ONE ANOTHER CAN BE CHANGED - A printing unit of a printing press is comprised of at least two frame parts, the position of at least one of which, relative to the other, can be changed. Cooperating ones of these frame parts are placed against each other along a common joining surface, in a first operational position. These frame parts are separated from each other in a second operational position. An interstice, that is partly defined by these frame parts, is formed between the separated frame parts in the printing unit. At least one of the cooperating frame parts is supported so that it is movable along an adjustment path. At least one sensor is provided and is usable to monitor the interstice. The sensor has orientation characteristics or a sensory range along the joining surface. An aperture width of a first angular aperture of the orientation characteristics or of the sensory range is smaller than a respective aperture width of a second or third angular aperture of the orientation characteristic or sensory range. The aperture width of the first angular aperture of the orientation characteristic or the sensory range is oriented parallel to the adjustment path of the movable frame path. The aperture width of the second angular aperture of the orientation characteristic or the sensory range is oriented in an axial direction of at least one printing group cylinder which is mounted on the movable frame panel. An aperture width of the third angular aperture of the orientation characteristic or the sensory range is oriented in the direction of a height of the movable frame panel. | 08-18-2011 |
20110197778 | METHOD FOR PROVIDING PRINTING FORMES AT INSTALLATION POSITIONS ON ONE OF A PLURALITY OF FORME CYLINDERS DISPOSED IN A PRINTING MACHINE PRESS AND FOR DISPOSING OF USED PRINTING FORMES FROM THE PRINTING PRESS - Printing plates are prepared at installation positions on one of a plurality of plate cylinders disposed in a printing machine. A plurality of flat printing plates, which are provided for a printing process to be carried out by the printing machine itself, and which printing plates are themselves bendable, at least along their length, are provided at the outlet of a plate line which is spatially separated from the printing machine and which comprises at least one plate exposure device. Each of the printing plates is temporarily stored in a specific shelf of a mobile collection container that has a plurality of such shelves. The printing plates which are stored in the same mobile collection containers are prepared for installation positions of the same plate cylinder. Each shelf of each of the mobile collection containers storing one of the printing plates is selected based on the intended installation position of the respective printing plate on the respective plate cylinder using data that is provided by a control unit of a production planning system. The data is provided prior to the storing of the printing plates. The printing plates which are stored in the mobile collection container, and which are to be provided to the same plate cylinder, are conveyed to the printing machine in a pre-sorted storage condition. | 08-18-2011 |
