Definitions

  • the invention relates to a method and a device for setting ink zone-wide ink metering elements according to the preamble of claims 1 and 4.
  • the invention has for its object to provide a method and a device with which it is possible to set a precise position of the ink metering elements despite playful drive.
  • the advantages of the invention are in particular that, despite play in the drive train for a color metering element, a very precise setting of the color metering elements is possible.
  • a simple position indicator for the ink metering elements can be created by balancing the steps with which the stepper motors are acted on.
  • Drives can be used to adjust the ink metering elements, which are not subject to high mechanical accuracy requirements and which are therefore very inexpensive. This is all the more important because a separate drive is required for each color metering element. It is also not necessary to know exactly the play in the drive elements in order to be able to carry out an exact adjustment of the ink metering elements in both directions. Match compensation can be carried out easily. The play compensation can also be easily adapted to progressive wear.
  • a driven ink fountain roller 2 is immersed in an ink fountain 1 of a rotary printing press.
  • a plurality of swiveling ink metering elements 3 are arranged in close proximity to one another in a known manner.
  • the ink metering elements 3 can be pivoted about a pivoting edge 4 of an ink fountain base 6 of the ink fountain 1.
  • the swivel arm 7 In its lower part 8, the swivel arm 7 is provided with an open control groove 9, which has two vertical control surfaces 10, 15.
  • the gearwheel 11 is positively or non-positively connected to a pinion 14 of a stepping motor 16 which can be operated with a reversal of the direction of rotation.
  • the drive for the color metering elements 3 each having a color metering edge 21 is not free of play.
  • Each of the drive elements 9, 12, 11, 13, 14 for the ink metering elements 3 can have a different game, the values of which add up to an overall game «a».
  • the size of the total play «a is determined and converted into adjustment steps of the stepper motor 16, whereby it is defined that an adjustment step is a process in which a motor shaft of a stepper motor 16 rotates by a precisely defined step angle (clockwise and counterclockwise rotation).
  • the ink metering element 3 Due to the pressure that a printing ink exerts in the ink fountain 1 due to its weight or when it is transported through an ink gap “b”, which is formed by the ink metering edge 21 and a circumference of the ink fountain roller 2, the ink metering element 3 is always in the same direction “ A »pivoted about the pivoting edge 4 (in the example clockwise, Fig. 1). That is, a right control surface 15 of the control groove 9 in the swivel arm 7 rests on the control roller 12.
  • the stepping motor 16 must have a number of Run "c" adjustment steps in a "minus direction", e.g. B. clockwise.
  • the pivot arm 7 is pivoted counterclockwise by means of the control roller 12. Compensation for the drive play in this direction is not necessary because the forces acting on the ink metering element 3 and thus on the swivel arm 7 via the printing ink in the ink fountain 1, the right control surface 15 of the control groove 9 is constantly pressed against the control roller 12.
  • the stepping motor 16 must have a number of « d »Run adjustment steps in a « plus direction » e.g. B. counterclockwise.
  • the pivot arm 7 is pivoted clockwise around the pivot edge 4 by means of the control roller 12. Because forces act on the ink in the ink fountain 1 on the ink metering element 3 and thus on the swivel arm 7, the right control surface 15 of the control groove 9 is pressed against the control roller 12.
  • control roller 12 does not have to run against the forces acting on the printing ink in the ink fountain 1 when the ink gap “b is enlarged, a play compensation must be carried out in this operating direction (A), with the transmission 9, 10, 15, 11, 13, 14 for the ink metering element 3, the stepper motor 16 covers a number of “a” adjustment steps in the “plus direction”.
  • the stepping motor 16 rotates in the opposite direction and resets the preselected amount “c” in the form of “c” adjustment steps without play compensation “a” and additional adjustment steps “z”.
  • the ink metering element 3 is always adjusted in the inventive direction from the same direction, ie from the same flank in the gear 9, 10, 15, 11, 13, 14. This will be explained with reference to FIG. 2.
  • the ink metering element 3 should be adjusted in the direction of “reducing the ink gap” by the number of “d” adjustment steps from a position “L”.
  • the control roller 12 lies in the starting position “L” on the right control surface 15 of the control groove 9.
  • the control roller 12 presses against the right control surface 15 of the control groove 9, then pivots the pivot arm 7 with the ink metering element 3 by «c» adjustment steps in the direction of «reducing the color gap», ie counterclockwise, to a position «M» which corresponds exactly to the desired adjustment value «c».
  • the control roller 12 also bears against the right control surface 15 of the control groove 9.
  • the ink metering element 3 is now to be pivoted from the position “M” by an amount “d” (it corresponds to the number “d” adjustment steps) in the direction “enlarge the color gap”.
  • Each of the ink metering elements 3 is adjusted by at least this amount ag when the ink metering elements 3 are adjusted counter to the direction of rotation “A of the ink fountain roller 2, or plus the additional amount“ z ”.
  • the play compensation can also be easily adapted to the wear of the components such as gears 11, 13, 14 and guides 10, 15 by adjusting the values for “a” or “a + z from time to time.
