Definitions

  • the invention relates to an ink fountain for a printing press with an ink fountain roller forming the front boundary, an ink knife running parallel to it and perpendicular to the axis of the ink fountain roller, on this and on the ink knife adjacent side walls, each consisting of a fixed and a connected to the Ink fountain roller consist of elastic part.
  • a paint box of this type is already known from DE-AS 1 162 852.
  • a bearing shoe connected to a side wall by an elastic material is pressed radially with a surface adapted to the curvature of the ink fountain roller.
  • the color knife which is adjustable by means of conventional ink zone screws, is arranged between the side walls and in each case abuts with a side surface against a side wall and the bearing shoe fastened with it.
  • the object of the invention is to develop an ink fountain of the type specified at the outset in such a way that ink cannot flow out on its sides either in the region of the ink fountain roller ends or between the side parts and the ink knife.
  • the ink fountain can be adjusted to an ink fountain roller 1 in a conventional manner from a traverse 2 running in the axial direction of the ink fountain roller 1 with an inclination towards the ink fountain roller and is delimited on both sides by side walls.
  • the ink fountain roller 1 itself gives the front (FIG. 1, right) limitation of the ink fountain 2. If necessary, a rear rear wall (not shown in more detail in FIG. 1) can also be used.
  • Each side wall consists of an outer end jaw 3, which is firmly connected to the ink fountain cross member 2 by fastening means.
  • fastening means e.g. B. cheese head screws 5, 6 are used.
  • An inner end jaw 4 can be attached to the outer stationary end jaws 3 by means of stud bolts 8, 9, 10 with nuts.
  • the side wall formed from an outer 3 and inner connecting jaws 4 is perpendicular to an ink knife 11, which is longer than the ink fountain roller 1 and thus protrudes at both ends over the front side A of the ink fountain roller 1.
  • the end jaws 3, 4 are held on the outer fixed end jaws 3 by means of the stud bolts 8, 9, 10, since these engage through threaded holes in the outer end jaw 3 in the tapped blind holes of the inner end jaw 4.
  • the inner end jaw 4 can be pressed onto the front side A of the ink fountain roller 1 and stands approximately vertically on an ink knife 11, which, as can be seen best in FIG .
  • Set screws 12, 13, 14 can be screwed into threaded through bores of the outer end jaw 3, which are preferably each provided with a blind hole into which compression springs can be inserted. 3, the inner end jaw 4 is pressed against the end face A of the ink fountain roller 1 by a compression spring 15 arranged in the adjusting screw 13.
  • the elastically fitting inner end jaws 4 follow as a result of heating processes outside, ie in the direction of the outer end jaw 3, so that an exact seal is always guaranteed, but the risk of seizure on the end face A can be avoided.
  • the surface of the inner end jaw 4 resting against the front side A of the ink fountain roller 1 is equipped with a wear-resistant layer which has good sliding properties.
  • a holder 16 On the outer end jaw 4, a holder 16 is fastened, which supports a compression spring 18 via a threaded pin 17, which always presses with its lower end (FIG. 3) the inner end jaws 4 with a suitable contact pressure via the seal 7 against the ink knife 11 . This also ensures a permanent closure between the inner end jaw 4 and the color knife 11.
  • the contact pressure between the inner end jaw 4 and the front side A of the ink fountain roller can be adjusted with the help of the studs 8, 9, 10 against the pressure of the springs.
  • the outer end jaw 3 is provided with a recess B which is able to accommodate the inner end jaw 4, so that the inner sides of the end jaws 3, 4 lie approximately in one plane.
  • the sides of the end jaws 3, 4 facing the ink knife 11 are provided with a groove in which the seal 7 is arranged in such a way that an exact seal is provided over the entire width of the ink knife 11.
  • the seal 7 achieves a seal between the end jaws 3, 4.
  • the exit of the seal 7 from the groove of the outer end jaw. 3 and the entry into the groove of the inner A end jaw 4 is so far apart that a sufficient relative displacement of the inner end jaw 4 relative to the outer end jaw 3 is given by the vertical leg of the seal 7.
  • a permanent contact of the inner end jaw 4 on the color knife 11 is thereby ensured under the action of the compression spring 18.
  • the vertical leg of the seal 7 (Fig. 1) is pressed with the aid of clamping strips 19, 20 (Fig. 2) by means of grub screws 21, 22 to the end jaws 3, 4, so that an exact seal is achieved.
  • a guide groove 23 is arranged in the outer end jaw 3, into which a corresponding elevation 24 of the inner end jaw 4 engages.
  • the inner end jaw 4 is preferably kept very narrow in the ink fountain roller ink knife area, end jaws, so that only this narrow area touches the ink knife 11. This has the advantage that in the event of an inclination of the color knife 1 in the longitudinal direction, no gap can arise from which the color could escape.
  • the end jaw 4 also touches the ink knife 11.
  • a vertically acting compression spring 18 was installed, which presses the end jaw 4 against the ink knife 11.
  • the end jaw 4 is provided with a bevel that corresponds to the angle that results from the point of contact of the ink knife 11 on the ink fountain roller 1.
