Definitions

  • the invention relates to a device for driving train roller pairs of a web-fed rotary printing press according to the preamble of claim 1.
  • a device of this kind is from Siemens / Energy & Automation vol. IX, no. 4, 1987, Berlin DE page 22.
  • the one input of the differential gear which is driven at a speed corresponding to the longitudinal shaft speed, is drivingly connected to the longitudinal shaft by means of a mechanical drive train indicated by a shaft.
  • the mechanical drive train mentioned is provided with a step gear. This must be adjusted each time the diameter of the forme cylinder changes, which can mean a high level of operating effort.
  • Another disadvantage is, of course, the structural outlay associated with a mechanical drive train of this type, including a step transmission.
  • FR-A 2 460 425 shows a drive device for a windable or windable web with two pulling devices, each of which has a differential gear with an output connected to the element to be driven and two inputs, one of which has a main motor for accomplishing the drive and one is connected to an auxiliary motor for regulating the web tension.
  • the two main motors are linked together in a cascade. However, no longitudinal shaft is used for this. Rather, the known arrangement is based on a constant drive of the main motors.
  • the auxiliary motors are only regulated depending on the web tension. Arrangements of this type can, however, prove to be very sluggish, so that there is a high risk of web breaks.
  • the drawing shows a block diagram of the drive device according to the invention assigned to a pull roller.
  • the pair of pull rollers 1 each comprises a driven roller and a non-driven roller rolling thereon.
  • a main motor 3 and a smaller auxiliary motor 4 are provided for driving the driven roller of the pair of draw rollers 1.
  • the main motor 3 has an output of about 25 kW, the auxiliary motor 4 of about 1 kW.
  • the main motor 3 and the auxiliary motor 4 are connected to the driven roller of the pair of pulling rollers 1 via a differential gear 5.
  • the main motor 3 and the auxiliary motor 4 are designed as DC motors, the speed of which is adapted to the speed of the longitudinal shaft 6, from which the drive of the printing units and the folder is derived.
  • the speed of the auxiliary motor 4 is also from the train, d. H. the tension of the paper web to be printed, depending.
  • the speed of the longitudinal shaft 6 is recorded by a pulse generator 7 driven by the latter.
  • the pulse generator 7 supplies pulse signals, which facilitates digital control of the motors 3, 4, the actual speed values of which can also be recorded by pulse generators.
  • the output signal of the pulse generator 7 forms the setpoint for a speed control loop 8 assigned to the main motor 3 and a speed control loop 9 assigned to the auxiliary motor 4.
  • the corresponding speed setpoint input of the control loop 8 or 9 is designated 10 or 11.
  • the speeds of the main motor 3 and the auxiliary motor 4 are also assigned by a respective Pulse generator 12 and 13 included, the output signals of which form the actual speed values for the control loops 8 and 9, respectively.
  • the corresponding actual value inputs of control loops 8 and 9 are designated 14 and 15, respectively.
  • the control circuit 8 assigned to the main motor 3 contains a speed controller 16, on which the speed setpoint input 10 and the speed actual value input 14 are located. Downstream of the speed controller 16 is a thyristor 17, which influences the energy supply to the main motor 3, as indicated by the signal line 18.
  • the thyristor 17 is a digitally controllable actuator. In the event of a deviation of the actual value entered into the controller 16 via the input 14 from the setpoint entered via the input 10 into the controller 16, the current supply to the main motor 3 is changed so that the deviation disappears.
  • the speed control circuit 9 assigned to the auxiliary motor 4 also contains a speed controller 19 which is followed by a thyristor 20 which influences the current supply to the auxiliary motor 4 via the signal line 21.
  • the speed controller 19 of the control circuit 9 has a third input 22, by means of which the speed setpoint value which can be input at the input 11 can be varied depending on the tension of the paper web to be printed.
  • the input 22 of the control loop 9 is accordingly the output of a web tension control loop 23 superordinate to the speed control loop 9. This results in a cascade control with an inner speed control loop and an outer, higher-level web tension control loop.
  • the web tension is recorded by means of a dancer roller 24 and a measuring element 25 assigned to it, the output of which is at the voltage actual value input 26 of a voltage regulator 27.
  • the voltage setpoint is specified by means of an adjustable potentiometer 28, the output of which is at the voltage setpoint input 29 of the voltage regulator 27.
  • the output of the voltage regulator 27 is located at the second setpoint input 22 of the speed regulator 19 of the subordinate speed control circuit 9. As already indicated above, this causes a voltage-dependent variation of the speed setpoint of the subordinate speed control circuit 9, which results in high accuracy and high security against web break etc.
  • the differential gear 5 connecting the main motor 3 and the auxiliary motor 4 with the driven roller of the pair of pulling rollers 1 is designed as a harmonic drive gear.
  • This contains, in a manner known per se, two rotating circular splines 30, 31, which are bridged by a so-called flex spline 32, which is received on a driven, oval wave generator 33.
  • the drive shaft 34 of the wave generator 33 is drivingly connected to the auxiliary motor 4 via a countershaft 35.
  • the circular spline 30 on the input side is connected to the main motor 3 via a flanged sleeve housing 36 and a shaft coupling 37.
  • a drive wheel 38 is flanged to the output-side circular spline 31, which meshes with a drive wheel 40 which is wedged onto the bearing journal 39 of the driven roller of the pair of pulling rollers 1.
  • the drive device shown of the pair of pulling rollers 1 via the speed-controlled main motor 3 and the speed and web voltage-controlled auxiliary motor 4 makes a mechanical connection of the pair of pulling rollers 1 with the longitudinal shaft 6 unnecessary.
