Definitions

  • the invention relates to a drive for cylinders of a rotary printing press according to the preamble of claim 1.
  • DE 195 01 243 A1 includes cylinders of a rotary printing press Bearrings known. Depending on one of these bearer rings Drive motor of the torque absorbed by the additional lubricant applied.
  • the DD 207 359 C describes cylinders of a web-fed rotary printing press different sized bearers.
  • the US 31 96 788 A shows transfer cylinders of a printing press with two Bearings of different sizes, one bearer the associated one Forme cylinder and the second bearer ring is assigned to the associated plate cylinder. Bearings of the same size roll on each other.
  • the invention has for its object to drive a cylinder To create rotary printing press.
  • This arrangement can also influence influences due to temperature differences can be compensated and thus an impermissible wear of bearer rings be avoided.
  • a printing point of a rotary printing machine is defined by a first cylinder 01, e.g. an impression cylinder 01 and a second cylinder 02, e.g. one Transfer cylinder 02 formed.
  • These cylinders 01, 02 are at both ends of their Bale 03, 04 each with a friction wheel 06, 07, a so-called bearer ring 06, 07 Mistake.
  • These bearer rings 06, 07 of adjacent cylinders 01, 02 roll in pairs each other and thus act as a friction gear.
  • a ratio of the radius r06 Bearings 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, i.e. 1.01> r06 / (r07 * N)> 1.001.
  • the bearer rings 06, 07 are approximately the same size, i.e. the integer multiples N is 1, i.e. 1.01> r06 / r07> 1.001.
  • the gear ratio of the first Friction gear e.g. due to the bale 03, 04 is almost the opposite Gear ratio of the second friction gear, e.g. as a result of the bearer rings 06, 07th
  • Process-related means, for example, that which exists during the printing process Bale 03, 04 friction wheel gear from transfer cylinder 02 and impression cylinder 01 with the interposition of a printing material or that between the forme cylinder and To understand transmission cylinders 02 existing friction gear.
  • the cylinders 01, 02 are provided with pins 08, 09, which by means of bearings 11, 12 in Side frames 13, 14 are mounted.
  • a center distance a1, e.g. B. a1 400.00 mm between the axes of rotation 16, 17 of the two cylinders 01, 02 can be changed.
  • 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 interlock, so that there is no positive drive connection between the two cylinders 01, 02.
  • other positive and frictional gears, z. 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. in the In the present case, the forme cylinder 27 is removed from the transfer cylinder 02 by means of a gearwheel driven out.
  • the forme cylinder 27 can also not be form-fitting to the Transfer cylinder 02 be coupled and have their own drive motor.
  • pressure points can be arranged, for example, in a five-cylinder printing unit, a ten-cylinder printing unit (FIG. 4) consisting of two five-cylinder printing units 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 changeable, for example by a rolling surface a tire 29 or tube having.
  • This tire 29 can be acted upon by a pressure medium, the pressure and thus the radius r28 and the transmitted torque of the friction wheel 28 can be set.
  • Another embodiment variant has additional friction wheels 31, 32, which both with the arranged on the cylinders 01, 02 friction wheels 06, 07 as well as with each other in Are in contact.
  • These friction wheels 31, 32 are, for example, on pivotable levers 33, 34 stored. Free ends of these levers 33, 34 are with an adjustable force acted on, so that there is a center distance a2 and a contact force F2 between the two additional friction wheels 31, 32 with each other and a center distance a3, a4 and a contact pressure F3, F4 between the additional friction wheels 31, 32 and on the Cylinders 01, 02 arranged friction wheels 06, 07 changed.
  • the friction wheels 06, 07 of the cylinders 01, 02 can as in the first embodiment additionally roll on top of each other or be spaced as shown, whereby in Operating state, the bales 03, 04 of the two cylinders 01, 02 interact.
  • the normal force between two interacting Friction wheels 06, 07 or 28, 07 or 31, 32 changed, i.e. the contact pressure between two Friction wheels 06, 07 or 28, 07 or 31, 32 and thus the transferable torque adjustable for example by means of a positioning drive 33.
  • the lever arms 33, 34 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 majority of the slip and thus also the Wear mainly between the friction wheels 31, 32 instead which for example are arranged that they are easier and cheaper to replace than on the cylinder 01, 02 arranged friction wheels 06, 07.
  • the torque of the drive motors 19, 21 is determined, for example by Power measurement.
  • the normal force between two friction wheels 06, 07 or 28, 07 or 31, 32 changed so that an amount of this difference of the two recorded power and / or torque output 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 in FIG. 7 shown schematically.
  • a first summation point is with the setpoint and an actual value of an angular position of the acts on the first drive motor 19 or the first cylinder 01 and indicates a signal a first PID controller.
  • the output of the PID controller applies a second one Summation point with a nominal value of an angular velocity. This An actual value of the angular velocity is applied to the summation point and there a signal to a second PID controller.
  • the output of the second PID controller applies a setpoint of a moment to a third summation point. This The third summation point is loaded with an actual value of the moment and enters 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 setting 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 become one Summation point supplied 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 with it Output signal is applied to a three-point controller.
  • the exit of the Three-point controller sends a signal for a setpoint to a summation point Manipulated variable, e.g.
  • This summation point is with the Actual value of this manipulated variable, in this example the position, is applied.
