- the opposite Friction rollers 62 and 72 more than two revolutions of the associated plate cylinder removed from the desired phase difference, so a plate cylinder 12 in a certain direction (for example forward) and another plate cylinder 22 in the opposite direction (backward).
- a desired phase shift between the friction rollers 42, 44 and 62 of the first printing unit 10 and the friction rollers 52, 54 , 72 of the second printing unit 20 assume different values which reduce vibrations of the printing press. The determination can be made using mathematical calculations or test results. If e.g. B.
- the friction rollers 42, 44 and 62 of the first printing unit 10 have a similar position, a similar weight and a similar vibration length as the friction rollers 52, 54, 72 of the second printing unit, it is to be anticipated that a phase shift of the rollers of 180 ° to one Minimization of vibrations would result because the roller 42 moves in the opposite direction to the roller 52, the roller 44 in the opposite direction to the roller 54, and the roller 62 in the opposite direction to the roller 72.
- Mathematical models can also be used to determine a desired phase shift of the rollers 42 and 25 when the rollers are at different heights.
- a resulting moment M for 24 friction rollers in a figure eight pressure tower can e.g. B.
- an accelerometer preferably a zero frequency accelerometer used to get actual values from those in the Printing machine 1 generated vibrations depending on the phase shifts rollers 42 and 52.
- a vibration sensor can be used to measure the vibrations 300 may be arranged on a frame 301 of the printing press 1. That way a desired one corresponding to a minimum vibration in the printing press 1 Phase shift can be determined.
- the printing press 1 further comprises a controller 80, which Receives inputs from sensors 142, 144, 152, 154, 162, 172 and counters 81 and 181 and controls the machine drive and motors 31 and 32.
- the controller 80 can comprise one or more processors, e.g. B. Intel Pentium processors as well their successors.
- the first motor 31 drives the first plate cylinder 12. Accordingly, The controller 80 can adjust the circumferential register of the first one via the motor 31 Effect plate cylinder.
- the circumferential register of the second plate cylinder 22 is about reaches the motor 32 and controller 80.
- At least one z. B. as Accelerometer trained vibration sensor 300 on the frame of the Printing machine 1 may be arranged.
- the printing press 1 is put into operation and the Degree of vibration of the printing press or a frame part of the printing press measured. If the vibration exceeds a desired limit value, the phase of the Rollers 24 and 52 changed to minimal vibration or vibration below to reach a certain limit. Then the production run of the Start machine.
- plate cylinder used here includes all types of image cylinders a, including z. B. also a digitally imageable cylinder without a printing plate.
- the desired phase shift can be an approximation of the press below a maximum operating vibration.
- the desired Phase shift can accordingly z. B. to a value within a fault tolerance of 6 °, for example.
- Fig. 1 only a single printing unit was explained in more detail; based on the drawing however, it is clear that a further printing unit is arranged above the first printing unit can. With this arrangement, the space requirement of the machine is reduced; through the However, the vibrating effect of the friction rollers is increased at the height of the printing units.
- the present invention is therefore particularly suitable for printing machines with one another arranged printing units suitable.
