Definitions

  • the invention relates to a transmission system for media such as paint, varnish or water in printing machines.
  • a variation of the amount of medium to be transferred is therefore still only possible by exchanging the anilox roller, ie replacing the anilox roller used by an anilox roller with a higher or lower scooping volume.
  • the transfer rate of the medium ink, varnish, etc.
  • the density values of the printed products are negatively influenced during ink application.
  • the object of the invention is to create a system for influencing the transmission rate of the medium provided by an anilox roller / chambered doctor blade system.
  • FIGS. 1-4 Different roller schemes are subsumed under the term transmission system, of which some roller schemes are exemplarily described in FIGS. 1-4.
  • 1 shows an anilox roller 1 with a chamber doctor blade 2 and a roller 3 arranged downstream of the anilox roller 1.
  • the roller 3 functions as an application roller 5 interacting with a forme cylinder 4. If intermediate rollers 5 are arranged between the anilox roller 1 and application roller 5, the roller acts Anilox roller downstream roller 3 as transfer roller 14 (Fig. 2).
  • 3 shows a roller diagram in which the applicator roller 3 arranged downstream of the anilox roller 1 is designed as an applicator cylinder 15 which is operatively connected to a forme cylinder 4.
  • 4 shows a variant in which the anilox roller 1 is operatively connected directly to a forme cylinder 4.
  • the anilox roller 1 is rotatably mounted in the machine frame 6.
  • the anilox roller 1 is connected to a drive wheel 7, the roller 3 designed as an application roller 5 is also rotatably mounted in the machine frame 6 and has a gear wheel 8.
  • the drive wheel 7 and the gear 8 are part of the drive wheel train 9 of the printing press.
  • a conversion element 10 which changes the speed of the anilox roller and thus its peripheral speed. It is also possible to assign the conversion element 10 to the transfer roller 14 (FIG. 2).
  • the synchronism behavior is changed, so that the transfer rate and, when ink is transferred, the density values of the same on the printing sheet.
  • a deviation from the synchronism behavior in the positive direction (increase in the number of revolutions) or negative direction (decrease in the number of revolutions) brings the same effect in changing the transmission rate.
  • the percentage difference in peripheral speed between anilox roller or transfer roller and downstream roller is in the range from 0.970 to 1.015.
  • the conversion element 10 is designed as a brake, clutch, gearbox or electric motor, for reasons of space, the use of a coupling in training as a rheological Coupling is advantageous.
  • the elements mentioned can be speed controlled and regulated.
  • Under Rheological coupling is understood to be a fluid coupling in which a controllable magnetic field is used the viscosity of the transmission fluid and thus the speed can be changed.
  • the conversion element 10 is part of a control loop which contains a control 13 connected to its first incremental encoder 11 arranged on the anilox roller and to a control 13 connected to a second incremental encoder arranged on the applicator roller.
