Definitions

  • the invention relates to an ink fountain for rotary printing presses juxtaposed zone-wide metering elements that are on different distance from an ink fountain roller are adjustable, wherein each dosing element seen in the axial direction of the ink fountain roller support and Has dosing areas and the support areas independently of each other Spring pressure is applied directly or indirectly to the ink fountain roller, the Dosing areas are wedge-shaped and the dosing elements are pivoted and can be covered by an elastic film attached to the ink fountain.
  • the object of the present invention is at by an elastic film covered dosing elements, wear z. B. to reduce the film.
  • the object is achieved in that the metering elements have a cylindrical metering area that on both sides of the metering areas the dosing elements are arranged support body and that the support body on her Have a flattened circumference with which they directly or indirectly under spring pressure lie against the outer surface of the ink fountain roller.
  • the cylindrical dosing range can be pivoted to adjust the ink film thickness, without the support body attached to it also this pivoting movement To run. Due to the flattening provided on the support body, the Support body to the outer surface of the ink fountain roller without it Follow the swivel movement of the dosing elements.
  • the flattening is like this trained that a surface contact between the support body and ink fountain roller exists, so that the contact pressure is reduced and the wear behavior of the film is significantly improved.
  • the fulcrum is the support body eccentrically offset on the dosing elements. This is a wedge-shaped course of the dosing areas with low manufacturing costs of the dosing elements.
  • the support bodies are in the form of support rings trained on both sides on eccentrically offset pins on the Dosing elements are arranged.
  • the Support bodies on eccentrically offset pins, with which they offset eccentrically Bores in the metering elements are rotatably mounted. Both versions ensure an independent pivoting of the dosing elements and a flat contact of the support body on the outer surface of the ink fountain roller or elastic film.
  • a further advantageous embodiment of the invention is characterized in that that the flats on the support bodies have an inward radius that corresponds approximately to the radius of the lateral surface of the ink fountain roller.
  • the Contact area optimally enlarged, so that a further reduction in wear reduced contact pressure is guaranteed.
  • the guides are designed as support bodies and designed to receive the metering elements fork-shaped, the fork-shaped Flattened ends.
  • Zone width metering elements 4 are in accordance with FIG Guides 5 held, which are supported by compression springs 6, so that the Dosing elements 4 are pressed against the outer surface of the ink fountain roller 2.
  • the metering elements 4 can be driven by means 7, threaded spindle 8 and Swivel the control body 9. To protect the dosing elements, these and the Guides 5 can be covered with an elastic film 10.
  • the dosing elements 4 are cylindrical Dosing area 11 provided on which an arm 12 for pivoting the Dosing element 4 is provided.
  • the arm 12 is via a coupling 13 with the Adjusting body 9 connected.
  • 2 to 4 are on both sides of the metering area 11 on the metering element 4 pins 14 are provided, on which Support rings 15 are rotatably placed.
  • the support rings 15 have flats 16 on with which they over the film 10 on the outer surface of the ink fountain roller 2nd issue.
  • the pin 14 are, as can be seen from Fig. 4, compared to the Dosing area 11 is offset eccentrically and the bores of the support rings are also offset eccentrically, so that the flat 16 with the largest Eccentricity of the metering area 11 matches.
  • Fig. 4 compared to the Dosing area 11 is offset eccentrically and the bores of the support rings are also offset eccentrically, so that the flat 16 with the largest Eccentricity of the metering area 11 matches.
  • metering elements 4 are shown, in which on both sides Bores 17 are provided, inserted into the pin 18 of support bodies 19 are.
  • the dosing areas 20 are cylindrical, so that they are at Swivel run wedge-shaped.
  • the support bodies 19 also have a flattened portion 21 on which rest against the ink fountain roller 2 via the film 10. 5 is the closed state of the metering area 20 and in Fig. 6 by turning the Dosing element 4 a gap between the metering area 20 and the outer surface of the Ink fountain roller 2 reproduced.
  • the eccentricity 21 of the pin 14 or the Bore 17 with pin 18 is the maximum desired Gap thickness 22 between the metering area 11, 20 and the outer surface of the Ink fountain roller 2 selected.
  • the flattening 16, 21 can the support bodies 15, 19 have a radius r inwards, which is approximately the radius corresponds to the lateral surface of the ink fountain roller 2.
  • FIG. 8 shows a guide 5 which is fork-shaped in the area of the metering elements 4 is formed and between the ends 23 each have a metering element 4 eccentrically arranged pin 14 receives.
  • Flattenings 16 at the ends 23 are directly or indirectly via the film 10 under spring pressure on the lateral surface of the Ink fountain roller 2.
