  • Friction wheels, Fig. 7 is a schematic representation of a control loop for adjusting the normal force between friction wheels.
  • a printing point of a rotary printing press is formed by a first cylinder 01, for example an impression cylinder 01 and a second cylinder 02, for example a transfer cylinder 02.
  • These cylinders 01, 02 are each provided with a friction wheel 06, 07, a so-called bearer ring 06, 07, at both ends of their bale 03, 04.
  • These bearer rings 06, 07 of adjacent cylinders 01, 02 roll on each other in pairs and thus act as a friction gear.
  • a radius r06, e.g. r06 200.2 mm
  • a ratio of the radius r06 of the bearer rings 06 of the first cylinder 01 to an integer multiple of the radius r07 of the bearer rings 07 of the second cylinder 02 is less than 1, 02 and greater than 1 , 0005, preferably less than 1, 01 and greater than 1, 001, ie 1.01> r06 / (r07 * N)> 1, 001.
  • the bearer rings 06, 07 are approximately the same size, i.e.
  • N is 1, i.e. 1, 01> r06 / r07> 1, 001.
  • a contact force between the bearer rings 06, 07 after a fixed presetting (e.g. assembly), but it is optionally possible.
  • This friction gear of the balls 03, 04 of the cylinders 01, 02 is the second additional friction gear, for example the bearer rings 06, 07 overlaid with a second transmission ratio.
  • the gear ratio of the first friction gear for example as a result of the bales 03, 04, is approximately the reverse of the gear ratio of the second friction gear, for example as a result of the bearer rings 06, 07. With the friction torque of the second friction gear, the friction torque of the first friction gear is approximately compensated.
  • “Process-related” means, for example, the friction wheel transmission of the bales 03, 04 of transfer cylinder 02 and impression cylinder 01 existing during the printing process with the interposition of a printing material or the friction wheel transmission existing between forme cylinder and transmission cylinders 02.
  • the cylinders 01, 02 are provided with pins 08, 09 which are mounted in side frames 13, 14 by means of bearings 11, 12.
  • the pins 09 are at least one of the two cylinders 01, e.g. of the transfer cylinder 02 stored in pivotable eccentric bushings 18.
  • Each of the two cylinders 01, 02 is assigned its own position-controlled drive motor 19, 21.
  • this drive motor 19, 21 has a gear pinion 22, 23 which engages in a gear wheel 24, 26 which is connected in a rotationally fixed manner to the pin 08, 09 of the respective cylinder 01, 02.
  • the gears 24, 26 of the two cylinders 01, 02 do not mesh, so that there is no positive drive connection between the two cylinders 01, 02.
  • gear drive shown instead of the gear drive shown, other positive and frictional gears such.
  • B. a toothed belt transmission can be used. It is also possible to connect the rotor of the drive motor 19, 21 directly to the pin 08, 09 of the cylinder 01, 02.
  • a forme cylinder 27 is assigned to the transfer cylinder 02, for example.
  • the forme cylinder 27 is driven from the transfer cylinder 02 by means of a gearwheel.
  • the forme cylinder 27 can also not be positively coupled to the transfer cylinder 02 and have its own drive motor.
  • These pressure points can be arranged, for example, in a five-cylinder printing unit, a ten-cylinder printing unit consisting of two five-cylinder printing units (FIG. 4) or a nine-cylinder printing unit (FIG. 5).
  • a pair of forme cylinders 27 and transfer cylinders 02 is assigned its own drive motor 21, and the associated counter-pressure cylinder 01 has its own drive motor 19 which is independent of the transfer cylinder 02.
  • the contact pressure between two friction wheels 28, 07 can be changed by, for example, a rolling surface having a tire 29 or hose.
  • This tire 29 can be acted upon by a pressure medium, the pressure of which and thus the radius r28 and the transmitted torque of the friction wheel 28 can be set.
  • a further embodiment variant has additional friction wheels 31, 32 which are in contact both with the friction wheels 06, 07 arranged on the cylinders 01, 02 and with one another.
  • These friction wheels 31, 32 are mounted, for example, on pivotable lifting legs 33, 34.
  • An adjustable force is applied to the free ends of these levers 33, 34, so that there is an axial distance a2 and a contact pressure F2 between the two additional friction wheels 31, 32 among one another and an axial distance a3, a4 and a contact force F3, F4 between the additional friction wheels 31 , 32 and the friction wheels 06, 07 arranged on the cylinders 01, 02 changed.
  • the friction wheels 06, 07 of the cylinders 01, 02 can also roll on one another or be spaced apart as shown, the bales 03, 04 of the two cylinders 01, 02 interacting in the operating state.
  • the normal force between two interacting friction wheels 06, 07 or 28, 07 or 31, 32 is changed, that is to say the contact force between two friction wheels 06, 07 or 28, 07 or 31, 32 and thus the transmissible torque adjustable for example by means of a positioning drive 33. Due to the chosen arrangement, e.g. B. by a suitable choice of the foot or pivot points of the lever arms 33, 34, it can be achieved that the normal forces between the friction wheels 31, 32 and the respective friction wheel 06, 07 are higher than between the friction wheels 06, 07.
  • the torque of the drive motors 19, 21 is determined, for example by measuring the power.
  • the normal force between two friction wheels 06, 07 or 28, 07 or 31, 32 is changed, so that an amount of this Difference between the two absorbed powers and / or given torques of the two drive motors 19, 21 is preferably minimal.
  • FIG. 7 An exemplary embodiment of a regulation for setting the normal force is shown schematically in FIG. 7.
  • a first summation point is subjected to the setpoint and an actual value of an angular position of the first drive motor 19 or first cylinder 01 and outputs a signal to a first PID controller.
  • the output of the PID controller applies a setpoint of an angular velocity to a second summation point. An actual value of the angular velocity is applied to this summation point and sends a signal to a second PID controller.
  • the output of the second PID controller applies a setpoint of a torque to a third summation point. An actual value of the moment is applied to this third summation point and sends a signal to a third PID controller.
  • the output of the third PID controller gives a signal for establishing a target value of a current for the first drive motor 19.
  • the control for the second drive motor 21 or cylinder 02 is carried out adequately.
  • a third control loop for adjusting the normal force between the friction wheels 06, 07 or 28, 07 or 31, 32 e.g. provided by means of a positioning drive 36.
  • the actual values of the moments of the two drive motors 19, 21 are fed to a summation point and the difference between the two actual values of the moments is formed.
  • This difference of the actual values and a target value of this difference of the moments of the two drive motors 19, 21 is fed to a further summation point and the output signal of which is applied to a three-point controller.
  • the output of the three-point controller sends a signal to a summation point for a setpoint of a manipulated variable, e.g.
  • this manipulated variable in this example the position, is applied to this summation point. From this summation point the input of a PID controller is acted upon, which in turn controls, for example, a drive motor 37 of the positioning drive 36 or a pressure control valve.
