Definitions

  • the invention relates to a method for controlling the sequence of a driven Ink application roller according to the preamble of claim 1 and a device to carry out the method according to the preamble of the independent claim 3rd
  • Potentiometers serving as actuators can also to be replaced by a pressure cell that has a measured value for delivers the contact pressure of the inking roller to the forme cylinder.
  • changes in diameter of the inking roller be compensated for, for example arise that the roller in operation due to the flexing work between their compliant covering and the printing form warmed, or by the fact that the roller for leveling the surface was ground a little thinner.
  • this arrangement cannot compensate for the different peripheral speed between inking roller and forme cylinders caused by changes in the applicator roller diameter is required as long as the inking roller and Forme cylinders, as is common, from a common one Drive driven with a fixed gear ratio become. Due to this lack of compensation of the peripheral speeds is not just an additional warming and thus also an additional enlargement of the roller diameter causes, but also an increased wear of the roller surface, because of this because of the different speeds with increased slip or sliding on the forme cylinder running.
  • German utility model 92 15 906.0 Inking unit known in which the inking roller on two Swivel levers is mounted with one end to one Forme cylinder axis parallel axis fixed to the frame swiveling are carrying the applicator roller in the middle between them and supported at the other end against adjustable stops are.
  • Compliant press assemblies push the other ends the two levers against the adjustable stops.
  • the temperature of the roller surface measured and the mentioned adjustable stops are with With the help of control signals determined by a computer in the Adjusted to keep the strip width constant.
  • the Problem of different peripheral speeds also not taken into account in the inking unit according to this utility model.
  • European patent application 406 737 proposes to Reduction due to constant roll diameter the necessary slip between the surface contact Roller and cylinder the outer diameter of the elastic Circumferential layer of the inking roller at the same speed of Roller and cylinder to 99% of the diameter of the same size Reduce forme cylinders. Because all parameters are constant remain, an adjustment of the peripheral speed of the Applicator roller to different diameters of the latter not reached.
  • a generic method and a generic printing unit are from DE-OS 32 39 114 A1 known.
  • a tachometer measures the speed of a plate cylinder and generates a variable control signal Speed control of an ink roller which is in operative connection Motors. This is intended to connect the surface wear to one another in direct Active cylinders, the peripheral speed between the plate cylinder resp. its extreme extent and the ink transfer roller balanced become.
  • the object of the present invention is now a control method and To create inking system, through which it is possible with changing diameters of the Inking roller e.g. due to heating or wear, the one deviating from the setpoint Speed of the inking roller and preferably also changes in the width of the application strip between the ink application roller, which has a resilient surface and automatically compensate for the forme cylinder.
  • the invention solves the problem, a control method and a To create inking system, through which it is possible, with yourself changing diameter of the inking roller e.g. due to warming or wear the speed deviating from the setpoint the inking roller and preferably also changes the application strip width between the one soft elastic Surface coating ink roller and the form cylinder to compensate automatically.
  • this peripheral speed not always exactly the same as the peripheral speed of the forme cylinder, because often due to the non-zero order strip width between Application roller and forme cylinder slip due to unavoidable a slight change in the peripheral speed of the Application roller can be reduced compared to that of the forme cylinder can.
  • the setpoint for the peripheral speed of the The application roller is therefore not necessarily equal to the actual value the circumferential speed of the forme cylinder. He will be on simplest determined empirically.

  • the circumferential speed of the forme cylinder becomes expedient or the speed proportional to this as electrical Signal introduced into the calculator.
  • the invention thus allows the peripheral speed of the Applicator roller, usually at the start of print production is selected, constant throughout the print production hold regardless of the running time initially rising surface temperature of the application roller.
  • the peripheral speed of the inking roller can be according to of the invention by detecting the speed the roller and the diameter thereof are detected. Of the The diameter of the same is appropriately dependent from the adjustment position of the application roller in relation to the Printing cylinder determined.
  • the regulation of the speed of the inking roller does not have to linear function of their diameter.
  • the relationship can also be used here as a non-linear function in the Calculator can be entered.
  • the speed of the inking roller can also be used as Function of the shore hardness of the coating of the inking roller be managed. The harder the surface, the lower it gets the pressure strip between the roller and cylinder and all the less can also be a possibly advantageous minor Reduction of the peripheral speed of the application roller compared to that of the impression cylinder.
  • the contact pressure or the dependent application strip width and the peripheral speed of the inking roller are of course regulated so that neither an uncontrolled Ink transfer still an undesirable Abrasion between printing form surface and application roller surface takes place.
