Definitions

  • the invention relates to a device for damping mechanical vibrations of printing presses.
  • the drive train of a printing press with the parts coupled to it is a system whose dynamics are determined by spring constants, moments of inertia, etc.
  • the rotating parts of this drive train can be excited to vibrate by the following influences.
  • Recurring load torque fluctuations are to be counted among the angle-dependent, i.e. synchronous vibrations, such as those caused by cam gears or by errors in single or n-speed gearwheels.
  • Vibrations that do not recur periodically with one revolution can be generated, for example, by periodic excitations that deviate from the rotational frequency. They occur, for example, due to belts, lifter knocks, or errors in half-speed gears. Even non-periodic noise processes, such as color splitting or the influence of the paper print, lead to asynchronous vibrations.
  • vibrations in the system can be caused by parameter fluctuations that have a low rate of change compared to sheet travel (for example, oil temperature fluctuations that affect the basic friction).
  • the invention is therefore based on the object of specifying a device and a method for damping mechanical vibrations of printing presses in order to improve the print quality.
  • At least one actuator assigned to the rotating parts of the printing press which is controlled by at least one vibration sensor arranged on the printing press in such a way that the actuating forces of the actuating member dampen the vibrations.
  • the device according to the invention is preferably intended to combat asynchronous interference. Since these disturbances essentially have small excitation energies, they can be set using relatively small actuating forces (compared to the total drive power) can be damped.
  • the vibrations are detected by at least one vibration sensor.
  • the data determined by the vibration sensor are evaluated and lead to the actuation of an actuating element which is designed as an active actuator.
  • the actuating forces applied by the actuator counteract the forces of the vibration excitation, so that damping occurs.
  • the damping of the non-synchronous interference prevents duplication, so that the print quality improves.
  • the actuator can be designed as a controllable eddy current brake. This is controlled according to the excitation frequency and thus actively intervenes in the overall system, as a result of which the asynchronous vibrations are eliminated.
  • the actuating element can be formed by a drive motor or an additional motor of the printing press.
  • the torque of a drive motor can be influenced, for example, by means of suitable components of the power electronics as a function of the data determined by the vibration sensor, so that the drive motor itself forms the actuating element and is used to reduce the vibration.
  • This increases the dual function of the drive motor, because on the one hand it delivers the drive power and on the other hand it has a vibration-damping effect.
  • an additional motor can also be present in the drive train of the printing press, which motor is controlled accordingly in order to reduce vibrations.
  • vibration sensor and the actuator are arranged in a control loop of a damping control device.
  • Training as a control loop always ensures that occurring, preferably asynchronous, vibrations are corrected to zero, as a result of which optimal damping can be achieved.
  • a plurality of vibration sensors and / or actuators are distributed over the drive train, in particular via a gear train, of the printing press.
  • the vibration forms required for damping can be derived very precisely, which are then preferably fed - possibly in a revised form - to several active actuators of the drive train.
  • the invention further relates to a method for damping mechanical vibrations which reduce print quality in the printing medium-carrying system of a printing press, the vibrations being recorded as a measured variable and used to generate actuating forces which have a vibration-damping effect on the printing medium-carrying system.
  • asynchronous vibrations that do not occur periodically with the revolutions of the rotating parts of the printing press are detected and damped.
  • the drawing illustrates the invention using various exemplary embodiments. It shows a schematic representation of a printing press with a device for vibration damping.
  • the figure shows a printing press 1 which has a plurality of printing units 2.
  • Each printing unit 2 has a plurality of cylinders and rollers, of which - for the sake of simplicity - only a part is shown.
  • Each printing unit 2 is driven by a drive motor (electric motor) M1, M3, M5, M n , M n + 2 , M n + 4 .
  • the individual printing units 2 are vibration sensors S2; S3, S4; S5; S n ; S n + 2 ; S n + 4 assigned, which are connected to a control device 3.
  • the far left in the figure printing unit 2 has the drive motor M1, which acts on the drive train of the printing press 1.
  • One of the rollers / cylinders of the printing unit 2 is assigned a vibration sensor S2, which is connected to the control device 3. From the control device 3 leads an operative connection to the drive motor M1.
  • the vibration sensor S2 senses occurring vibrations of the associated printing unit 2 and forwards corresponding data to the control device 3. This carries out an evaluation. In particular, periodic vibrations are not detected and a control variable is formed which reacts on the drive motor M 1.
  • the drive motor M1 thus forms an actuator B1.
  • the control of the motor M 1 takes place in such a way that it does not deliver a constant drive torque, but because of the special control by the control device 3 additionally applies actuating forces which counteract the asynchronous vibrations, so that vibration damping results overall.
  • the second printing unit 2 from the left shows a corresponding arrangement in the figure, as with the leftmost printing unit 2, but there is the difference that Several vibration sensors, namely S3 and S4, are provided, which detect the vibrations at different points in the drive train and feed the relevant data to the control device 3.
  • a drive motor can be used as an actuator. This is the motor M3.
  • the third printing unit 2 from the left in the figure shows a further exemplary embodiment.
  • two elements are used as actuators for applying the actuating forces. These are the drive motor M5, which acts as an actuator B5 and an additional motor M 5 ' , which acts at another point on the drive train and acts as an actuator B 5' . Both motors are controlled by the control device 3 in such a way that their given moments are set in accordance with the required drive power and also with regard to the damping of asynchronous vibrations.
  • control device 3 additionally controls an eddy current brake W, which actively acts on the associated drive train of the printing unit 2 in order to increase the vibrations that occur dampen.
