Embodiment Construction

[0013] figure 1 A printing press with four printing devices 1-4, a feeder 5 and a receiver 6 is shown. The rollers 7 or cylinders 8 of the printing devices 1-4 are coupled to each other via a gear system 9. The motor 10 is used to drive the roller 7 or the drum 8. The rollers or sheet stack elevators in the feeder 5 and the receiver 6 are driven by separate motors 11,12. There are a large number of power consumers in the printing device 1-4, such as auxiliary motors 13-16 and electromechanical actuators 17-20. A dryer 21 having a heating winding 22 is provided in the receiver.

[0014] The power consumers of the printing press are grouped and have different current loops. The electric motors 10 and 12 constitute a first group of power consumers in the first circuit 23, which can be separated from the current supply unit 25 through the first switching element 24. The motor 11 belongs to a second group of power consumers arranged in a loop 26, which can be separated from the cu...

Abstract

A method for delivering electric power to power consumers of a printing technology machine, which permits high availability of the machine with low idling losses, includes taking start-up time periods of the power consumers into account when switching over the power delivery to power consumers of a printing machine.

Description

Technical field [0001] The present invention relates to a method for outputting electrical power to a power consumer of a printing technology machine, wherein the power output is switched between the preparation operation and the working operation of the machine. Background technique [0002] In order to operate printing technology machines such as printing presses, die cutters, paper processors or bookbinding machines, power consumers such as motors, electromechanical actuators, heating and cooling units, measuring devices, control devices and regulating devices are supplied with current. The power output to the power consumer is determined in such a way that all operation processes necessary for the working operation of the machine operate reliably. During machine operation, the power output fluctuates according to the number of power consumers and power demand. [0003] It is known to temporarily switch off the current supply of power consumers that are not required during oper...
