Embodiment Construction

[0015] figure 1 shows a very simplified block diagram of the control aspects of a sheet-fed printing machine according to the invention, wherein the sheet-fed printing machine according to the invention has a main drive mechanism 10 which is in figure 1 Drives the rubber cylinder 11 of a printing mechanism of a sheet-fed printing press. The plate cylinder 12 of the printing unit is driven by a separate drive unit 13 . The plate cylinder 12 is thus the motorized unit of the sheet-fed printing press itself.

[0016] It should be pointed out here that a sheet-fed printing press can comprise several main drives. In addition, printing presses of this type can usually also comprise a plurality of printing units, each of which has a plate cylinder which is itself motorized. because figure 1 For the sake of simplicity, only the rubber cylinder 11 and the plate cylinder 12 of the printing mechanism are shown, wherein the rubber cylinder 11 is driven by the main drive mechanism 10 a...

Abstract

The press is equipped with some printing units, the printing unit respectively comprises an impression cylinder, the rubber cylinder, a cylinder of ink arrangement or a roller, the printing unit further includes the plate cylinder capable of being independently driven with an exclusive motor, and the rubber cylinder and the plate cylinder can be respectively connected or released from connection. In that case, a first controller which is carried out immediately after generation of a phenomenon concerning safety, a synchronous driving between a cylinder or a roller of the printing unit driven with each main driving part and the plate cylinder is carried out immediately after generating a phenomenon concerning safety. The synchronous motion is carried out by concluding single or each switchable clutch; between each rubber cylinder and each plate cylinder of the printing unit and by switching the driving part of the plate cylinder.

Description

technical field [0001] The invention relates to a printing press, in particular a sheet-fed printing press, according to the preamble of claim 1, and a method for driving a printing press, in particular a sheet-fed printing press, according to the preamble of claim 6 . Background technique [0002] Printing presses have a large number of devices which have to be driven during a printing, adjustment or maintenance operation of the printing press. In the case of a conventional configuration, all the devices of the printing press to be driven are driven by a so-called main drive of the printing press. All devices to be driven are usually mechanically connected to the main drive via transmissions or toothed belts. [0003] In modern designs of printing presses at least some of the devices to be driven are themselves driven motorized. It is therefore known from the prior art to drive the plate cylinders or paper cylinders of the printing unit in a printing press in a manner su...
