  • Each drive of the printing press is assigned a separate drive controller, each drive forming a drive control loop together with the respective drive controller, and wherein the respective drive controller generates a control signal for the corresponding drive of the drive control loop on the basis of a deviation between a desired value and an actual value.
  • the present invention is based on the problem to provide a novel printing press and a novel method for operating a printing press.
  • At least one drive controller is associated with a device which generates online during the operation of the printing machine from at least one state variable of the drive control loop, in which the respective drive controller is integrated, a torsional vibration compensation variable, which is valid exclusively in this drive control loop for torsional vibration compensation.
  • At least one state variable of at least one drive control loop of the printing machine for the drive controller of this drive control loop generates a rotational vibration compensation variable that is valid or used exclusively in this drive control loop for torsional vibration compensation. No modal analysis of the press is required for this.
  • the invention is characterized by a high degree of robustness and reliability in torsional vibration compensation. Of the Effort for a torsional vibration compensation is minimized with the present invention.
  • the device associated with a drive controller comprises a first means for detecting from the or each state variable of the respective drive control loop a torsional vibration of the respective driven cylinder to be compensated, and a second means for generating from the detected torsional vibration the torsional vibration compensation variable for the respective drive control loop, wherein the first means and the second means of the device associated with the drive controller each comprise at least one function, and wherein at least one parameter of these functions in the sense of an adaptation online during the operation of the printing machine is adaptable.
  • each of the printing units 10, 11, 12 and 13 of the sheet-fed printing press comprises according to Fig. 1 an impression cylinder 14, a transfer cylinder 15, an inking unit 16 and a forme cylinder 17.
  • each printing unit may also include a dampening unit.
  • one transfer cylinder 18 is positioned in each case in order to transfer printing material sheets to be printed between the individual printing units 10, 11, 12 and 13.
  • the printing machine has a main drive 19, wherein the main drive 19 drives into the impression cylinder 14 of the printing unit 10.
  • the main drive 19 are all the impression cylinder 14, transfer cylinder 15 and inking 16 of the printing units 10, 11, 12 and 13 and the transfer cylinder 18 in the sense of a closed Räderzugs drivable.
  • a further main drive 19 ' is present to drive decentralized in the closed gear train.
  • Each form cylinder 17 is associated with a separate direct drive 20 to drive the form cylinder 17 of all printing units 10, 11, 12 and 13 intrinsically.
  • Each form cylinder 17 of each printing unit 10, 11, 12 and 13 is in this case via a clutch 21 from the closed gear train, in which the impression cylinder 14, the transfer cylinder 15, the inking units 16 and the transfer cylinder 18 are integrated, uncoupled. Accordingly, when the forme cylinders 17 are driven by their direct drives 20 on their own power, the clutches 21 are opened in order to decouple the forme cylinders 17 on the drive side from the rest of the printing units or printing press.
  • Fig. 2 shows details of the drive controls the form cylinder 17 of the printing units 10, 11, 12 and 13 by the same associated direct drives 20. So can Fig. 2 be taken that each direct drive 20 of each printing unit 10, 11, 12 and 13 is assigned a respective drive controller 22. The controller 22 generates based on a control deviation between a setpoint and an actual value a manipulated variable for the direct drive 20 of the printing unit. The actual value is preferably an actual position value of the drive to be driven by the direct drive 20 Form cylinder 17 of the respective printing unit, this actual position value of the forme cylinder 17 is provided by a same associated position sensor 23.
  • the desired value is preferably the position actual value of the transfer cylinder 15 of the respective printing group 10, 11, 12 or 13 cooperating with the forme cylinder 17, this position actual value of the transfer cylinder 15 being provided by a position sensor 24 assigned to it.
  • a control deviation between this actual value and this setpoint is, as already mentioned, supplied to the drive controller 22, wherein the drive controller 22 generates an actuating signal for the direct drive 20 of the forme cylinder 17 of the respective printing unit 10, 11, 12 or 13 based on this control deviation.
  • the drive controller 22 of the direct drive 20 assigns to the drive controller 22 of the direct drive 20 at least one printing unit, preferably the drive controller 22 of the direct drive 20 of each printing unit, a device 25 which is online during operation of the printing machine from at least one state variable of the corresponding drive control loop, in which the respective drive controller 22 is integrated, generates a torsional vibration compensation variable which is used exclusively in this drive control loop for torsional vibration compensation or is valid for this drive control loop.
  • each drive controller 22 of each direct drive 20 of each printing unit 10, 11, 12 and 13 is associated with such a device 25, which generates a valid only for the respective drive controller 22 torsional vibration compensation quantity.
  • the state variable from which the torsional vibration compensation variable is generated online during operation is the actual value of the respective drive control loop, namely the actual position of the corresponding forme cylinder 17. It should be noted at this point that when a real leading axis of the printing machine is present , in addition to or as an alternative to the actual value of the respective drive control loop, also the desired value of the respective drive Drive control loop, namely the actual position of the corresponding transfer cylinder 15, can be used. Also can be used as a state variable from which the torsional vibration compensation quantity is generated online during operation, a motor current or an engine speed of the direct drive 20 or any other control technical state variable of the respective drive control loop.
  • the device 25 assigned to each drive controller 22 of each direct drive 20 has a first means for detecting a rotational vibration of the driven forme cylinder 17 to be compensated from the or each state variable of the respective drive control loop, here from the actual position value of the forme cylinder 17. Furthermore, this device 25 has a second means for generating the torsional vibration compensation variable for the respective drive control loop from the detected torsional vibration.
  • Each drive controller 22 is preferably designed as a cascaded controller from a current control, speed control and position control.
  • the rotational vibration compensation variable generated for the respective drive controller 22 with the aid of the device 25 can be used in the current control, speed control and position control of the respective drive controller 22.
  • the torsional vibration compensation variable can be a current variable, rotational speed variable or position variable which is acted upon as compensation variable of the current control, rotational speed control or position control.
  • the regulation according to the invention for torsional vibration compensation changes online during the operation of the printing machine in the sense of an adaptation.
  • the first means and the second means of a device 25 associated with each drive controller 22 each comprise at least one function, wherein at least one parameter of these functions in the sense of an adaptation can be adapted online during the operation of the printing machine.
  • the adaptation can be based on the evaluation of an additional criterion, such. As a maximum lag error or temporary lag error, to particularly interesting operating points, in order to generate correspondingly adapted torsional vibration compensation variables.
  • the torsional vibration compensation quantities are time-variable compensation quantities.
  • each printing unit 10, 11, 12 and 13 each associated with a direct drive 20, regardless of the other printing units online during operation of the printing press torsional vibration compensation.
  • This torsional vibration compensation takes place using the already existing rotary encoder 23, 24 of the forme cylinder 17 and transfer cylinder 15 of the respective printing units.
  • each drive controller 22 of each direct drive 20 of each printing unit is associated with a device 25 for torsional vibration compensation, which individually generates a torsional vibration compensation variable for each drive controller 22 and thus for each printing unit.
  • the above torsional vibration compensation is preferably limited to the direct drives 20 and the direct drive 20 associated drive controller 22. Alternatively, however, it is also possible to use this torsional vibration compensation on the or each main drive 19, 19 'of the printing press, in which case the drive regulators of the main drives 19, 19' are assigned a device for generating an individual torsional vibration compensation variable.
  • the invention can also be used in printing presses whose printing units have no direct drives, but which exclusively comprises a plurality of main drives.
