Definitions

  • the present invention relates to an ink chamber doctor blade for a Ink application roller of a printing press, with a squeegee box with ink chamber and two over each other on each side the length of a doctor knife extending ink exit opening.
  • the chambered doctor blades are used to feed and distribute the desired ones Ink on the inking roller, e.g. the anilox roller one Printing press.
  • the permanently installed Chamber squeegee can be disassembled, whatever also with more or less big loss of color (sometimes expensive products).
  • the object of the present invention was to attach the To simplify chambered doctor blades and to design them in such a way that as little color as possible is lost when changing goes.
  • the chambered doctor blade is intended in particular for machines new color change systems.
  • the sealing strip designed as a sealing strip the squeegee box in the form of an easily and quickly replaceable Form the cassette, without loss of color and without special Precautions (after loosening the paint supply and discharge connections.
  • the ink feed system can be cleaned by any method and provide for a new color.
  • the press is just a new cassette (Chamber doctor blade).
  • Figure 1 of the drawing shows a section of a printing press purely schematically, in addition to an inking roller 1 the ink chamber doctor blade 2 of interest here is illustrated.
  • the doctor box 3 with the ink chamber 4 is on a carrier 5 mounted, which is adjustable in the direction of the arrow to adjust the pressure of the doctor blade 2 on the roller 1. this happens via an actuator 6 (e.g. hydraulic or pneumatic cylinder).
  • an actuator 6 e.g. hydraulic or pneumatic cylinder
  • the doctor blade 2 with carrier 5 and associated components on a plate 7 which can be pivoted in a vertical plane mounted, which allows the squeegee 2 in any angular position 2 ', 2' 'with respect to the roller 1 (depending on Type of paint to be applied or remaining in the paint chamber 4 Amount of paint to optimally fill the "well” the anilox roller through support by the weight of the ink, if necessary, taking into account the speed of the process, to achieve).
  • the pivoting takes place e.g. via the actuator 6 '.
  • the color itself is connected via supply or discharge connections, e.g. 8th or 9 (Fig. 2) into the ink chamber 4 (from not shown Paint vessels).
  • the sealing strip 10 which can be seen via an actuator 11 from a non-operating position to the right into a Position can be moved in which the sealing strip 10th pressed against the inside of the edges of the doctor blades 12, 13 can be.
  • the color outlet is by spreading the entire width of the squeegee extending gap formed.
  • the doctor blade box 3 can be designed and assembled as a cassette be what allows a quick exchange when changing colors (after loosening and closing the ink supply and discharge connections).
  • At least the effective surface of the sealing strip 10 exists made of elastomeric material.
  • the cross section of the bar can e.g. rectangular or circular or a combination.
  • FIG. 2 of the drawing shows another, somewhat more detailed Principle view of the construction according to the invention. It will for the same parts the same transfer numbers as in FIG. 1 used.
  • the doctor blade 2 is on a support 5 and one vertically around the roller axis pivotable plate 7 as replaceable Cassette mounted and is against the Roller 1 (anilox roller) held. Via connections 8 and 9 respectively the doctor blade chamber 4 ink supplied or removed.
  • the chamber 4 has a cross section in the form of a lying U on, due to a protruding into the chamber 4 15 for a sealing strip 10, which from the inactive position (left) to the right in the active closing position 10 ' can be moved.
  • the sealing strip is in this position 10 'sealing against the inside of doctor blades 12, 13 and closes it over the entire width of the squeegee box 3 extending color outlet opening 14. With this closed Opening 14, the cassette can be removed without the risk of unwanted color leakage.
  • the scraper plate is guided on guide rods 16, 17 by one chamber wall can be moved to the other, and grazes paint adhering to the longitudinal walls of the chamber to push back into the supply and discharge lines (chamber pre-cleaning), before washing the cassette in the machine is suspended or replaced. For one Color change, the supply and discharge system is cleaned separately.
  • the manual pivotability the carrier plate 7 shown.
  • the support structure can be locked in the angular position 18 block (in the example shown: pivoting option up to 90 °).
