Definitions

  • the present invention relates to a printing machine with a Farbschrakel and an inking roller, with a holder to hold the ink chamber doctor blade in a predetermined position to the inking roller and press on the latter.
  • the chamber blade serves to supply and distribute the desired color to the inking roller, z. B. the anilox roller of a printing press.
  • the chambered doctor blade is fixedly arranged in a predetermined angular position relative to the inking roller. Such a construction can not ensure optimal filling of the "wells" of the anilox roller with different color consistency and / or printing speed.
  • Object of the present invention was to provide a printing machine with Farbschrakel, which allows optimal ink supply to the inking roller.
  • Print speed fill the "wells" of the anilox roller optimally. Even with unwanted demixing of the color (heavy color parts below), this goal can easily be achieved with a suitable angular position.
  • the optimum angle adjustment of the doctoring chamber can also be achieved automatically by means of a control device as a function of process parameters.
  • FIG. 1 The drawing shows a section of a printing machine purely schematically, wherein in addition to an inking roller 1, the color chamber blade 2 of interest here is illustrated.
  • the doctor box 3 with the ink chamber 4 is mounted on a support 5 which is adjustable in the arrow direction to adjust the pressure of the doctor blade 2 to the roller 1. This is done via an actuator 6 (e.g., hydraulic or pneumatic cylinders).
  • an actuator 6 e.g., hydraulic or pneumatic cylinders.
  • the chambered doctor blade 2 with support 5 and associated components is mounted on a pivotable in a vertical plane about the axis of the roller 1 plate 7, which allows the doctor blade 2 in any angular positions 2 ', 2 "with respect to the roller 1 to pivot (Depending on the nature of the paint to be applied or remaining in the ink chamber 4 amount of ink to achieve optimum filling of the "wells" of the anilox roller by supporting the weight of the color, optionally taking into account the process speed).
  • the pivoting takes place for example via the actuator 6 '.
  • FIG. 2 The drawing shows a further, somewhat more detailed principle view of the inventive construction. It will be the same transfer numbers for the same parts as in FIG. 1 used.
  • the chambered doctor blade 2 is mounted on a support 5 and a vertically pivotable plate 7 as an exchangeable cassette and is held with a predetermined force against the roller 1 (anilox roller).
  • FIG. 2 the manual pivoting of the support plate 7 is shown.
  • the support structure can be blocked in detents 18 (in the example shown: pivoting up to 90 °).
  • the chambered doctor blade 2 can always bring and lock in an optimal angular position to the roller 1. This ensures optimum filling of the "cups" of the anilox roller 1.
  • the pivoting may vary depending on procedural parameters, e.g. Color consistency, color weight and / or print speed automatically done.
