Abstract
A drive for a sheet-fed printing machine, in particular a sheet-fed offset printing machine is described, in which the individual cylinders and/or drums and the plate or form cylinders are driven by a common drive train. In order to allow automated operations to proceed simultaneously, clutches are arranged in the drive trains of the individual plate or form cylinders and, furthermore, the individual plate or form cylinders are assigned drive motors which can be controlled separately and by means of which the plate or form cylinders can be driven in the intended manner after corresponding disengagement.
Claims12
A drive for a sheet-fed offset printing machine, in which plate or form cylinders arranged in individual printing units of the machine are driven by a common train of gears, each of the plate or form cylinders is associated with a remotely actuable clutch and a controllable drive for driving the plate or form cylinder, and a drive control for controlling the controllable drives and clutches, wherein when the clutch is actuated, the plate or form cylinder is decoupled from the common gear train to be driven by the controllable drive and is exchangeable with a new plate or form cylinder, the remaining cylinders being driven by the common gear train.
In a sheet-fed offset printing press having inking and/or dampening systems, a drive for plate or form cylinders of individual print units of the press, the drive comprising:
- a common gear mechanism powered by a main drive for driving all of the cylinders, a coupling and localized drive for one or more of the cylinders for at least one of the printing units, each of the localized drives and the couplings for one of the printing units have assigned to them an interactive drive control in communication with the main drive in order for the one or more cylinders of the printing unit to be disengaged from the main drive and brought on-line to the localized drive for automatically exchanging plate or form cylinders of the printing units when the coupling is disengaged while the remaining cylinders continue to be driven by the main drive.
