Definitions

  • the invention relates to an ink fountain for rotary printing presses arranged side by side and at different distances from one another Ink fountain roller adjustable, cylindrical dosing elements, each one wedge-shaped dosing range determined, rotatably mounted and with a Ink box attached elastic film is covered, the dosing elements Support bodies or areas are assigned, each of which is under spring pressure, lies indirectly over the film on a lateral surface of the ink fountain roller, according to Preamble of claim 1.
  • EP 0 021 002 A1 contains a color box corresponding to the type mentioned at the outset described in which an offset seen in the circumferential direction of the ink fountain roller between the support bodies or areas and the metering areas (cf. EP 0 021 002 A1, Figure 6, position 17, 30) and the metering range of each metering element extends across the full zone width.
  • the object of the present invention is when covered by an elastic film Dosing elements, wear, e.g. B. on the film to reduce.
  • the object is achieved by a color box with the features of Claim 1 solved.
  • the wedge-shaped metering area can be used to adjust the ink film thickness be pivoted without the support body attached to this pivoting movement also run. Due to the flattening provided on the support bodies, the Support body to the outer surface of the ink fountain roller without causing the pivoting movement follow the dosing elements.
  • the flattening is designed so that a There is surface contact between the support body and ink fountain roller, so that the Contact pressure is reduced and the wear behavior of the film is significantly improved.
  • the fulcrum of the support body is on the Dosing elements offset eccentrically. This is a wedge-shaped course of the Dosing ranges achieved with low manufacturing costs of the dosing elements.
  • the support bodies are in the form of support rings formed on both sides on eccentrically offset pins on the metering elements are arranged.
  • the support bodies are eccentric offset pins, with which they in eccentrically offset holes in the Dosing elements are rotatably mounted. Both versions guarantee an independent Swiveling the metering elements and a flat contact of the support body on the Shell surface of the ink fountain roller over the 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 are and Guides 5 covered with an elastic film 10.
  • the metering elements 4 are wedge-shaped 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 metering areas 20 are wedge-shaped, so that when they are Swivel run wedge-shaped.
  • the bores 17 and the pins 18 eccentrically offset from the metering area 20, so that when Rotating the metering element 4 of the gap to the lateral surface of the ink fountain roller 2 can be adjusted.
  • 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.
  • 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 body 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 indirectly via the film 10 under spring pressure on the lateral surface of the Ink fountain roller 2.
