Definitions

  • the invention relates to an ink fountain for offset or high-pressure machines with ink metering device which interacts with an ink fountain roller.
  • Ink boxes are known in which the side parts are screwed or pinned to the ink box body.
  • the purpose of this measure is to prevent the undesired leakage of color in the joining area between the ink knife and the respective ink fountain side part.
  • ink fountain side part - which is attached directly to the end of the ink knife and thus directly dependent on it - can no longer prevent the ink from escaping because the necessary adjustment to the Ink fountain roller face, which is required for sealing, is no longer guaranteed due to the too large free space between the ink fountain roller face and the ink fountain side part.
  • DE-B 11 62 852 shows a technical teaching in which the end face of the side part facing the ink fountain roller is provided with a recess corresponding to the surface curvature of the ink fountain roller and this end face is placed against the outer surface of the ink fountain roller.
  • a sealing material is provided. As long as the side part is in the actual basic position against the roller surface, this prevents the ink from running out.
  • the object of the application is to achieve optimization in the areas of adjustability, sealing and manufacturing or assembly costs.
  • the advantages that can be achieved with the subject of the application, in addition to increasing the ink fountain seal, are primarily that the manufacturing outlay for the respective individual components is reduced and that the time for completing the ink fountain is also reduced without any restrictions in terms of the sealability.
  • Another advantage arises from the almost total negligibility of the heat coefficient, which opens up new perspectives for the material selection.
  • the subject of the application allows easy removal of the ink fountain side parts, which is not least important when cleaning the ink fountain.
  • Another advantage can be seen in the fact that the adjustment of the ink fountain side part caused by spring force enables the ink fountain to be swiveled slightly to adjust the overall color profile without impairing its function.
  • the end face of the ink fountain side part is provided with a recess corresponding to the surface curvature of the ink fountain roller so that the entire end face can be placed against the ink fountain roller, thus preventing the ink from leaking in the entire height region of the ink fountain side part.
  • the end face of the ink fountain side part is formed from a lubricant-separating material (plastic) in a further embodiment of the application.
  • spring elements are provided in one embodiment of the object of the application, which on the one hand exerts a force directed towards the ink fountain roller - which in particular targets the area below the ink fountain roller axis - and on the other hand exerts a force directed towards the ink fountain knife on the side part and thus preventing the paint from leaking.
  • a guide element which has a right angle to the color knife Has guide groove.
  • a bolt is embedded in the bottom surface of the guide groove, the ball-shaped head of which is raised to the bottom surface. This ball-shaped bolt end forms the only support point for the ink fountain side part, which also enables the side part to be tilted about this support point.
  • the ink fountain roller 1 shown in FIG. 1 is assigned an ink fountain 2 which is arranged such that it can be pivoted away from the ink fountain roller 1 via a pivot point 3.
  • the ink fountain 2 is delimited on each of the two end faces by a ink fountain side part 4.
  • the end face 12 of the ink fountain side part 4 is provided with a recess corresponding to the surface curvature of the ink fountain roller 1, thereby preventing the ink from leaking in this contacting area.
  • the necessary mobility of the ink fountain side part 4 is achieved in that the ink fountain side part 4 is arranged to be movable relative to the ink fountain 2 and the ink fountain roller 1.
  • a guide groove 13, which is illustrated in FIG. 2 and is adjacent to the ink knife 11, is provided and serves to receive the ink fountain side part 4.
  • the outside of the guide groove 13 forms the guide jaw 5 by two spring elements 10 located at the level of the color knife 11. These spring elements 10 exert a force on the ink fountain side part 4 in such a way that the ink fountain side part 4 is pressed against the ink knife 11.
  • the guide groove 13 is wider than the ink fountain side part 4, so that the ink fountain side part has a freedom of movement 15 between the ink knife 11 and guide jaws 5.
  • the freedom of movement 15 enables an extended tolerance range in the manufacture of the ink knife 11 and ink fountain side part 4 and ensures the mobility of the ink fountain side part 4 required for tracking the ink fountain 4.
  • a bolt 8 is embedded in the bottom surface of the guide groove 13, the end of the bolt being raised to the bottom surface and forming the only support point 9 for the ink fountain side part 4, whereby mobility or tilting of the ink fountain side part 4 around this support point 9 is ensured.
  • the ink fountain side part 4 lies securely on the support point 9 in that the force generated by the spring element 6 acts on the region below the axis of the ink fountain roller 1, as a result of which the resulting force is directed onto the support point 9. Furthermore, the existing between the end face 12 of the ink fountain side part 4 and the lateral surface of the ink fountain roller 1 causes an increase in the contact force at the contact point 9.
  • a slight pivoting of the ink fountain 2 around the pivot point 3 also causes a pivoting and tracking of the ink fountain side part 4 in the opposite direction around the support point 9, whereby the necessary seal between the end face 12 and the surface of the ink fountain roller 1 is maintained.
  • the above-mentioned embodiment represents only one embodiment, in particular it is also possible to provide other types of point supports having the same effect. It would also be conceivable to form the support surface of the ink fountain side part 4 locally as a point support, so that the ink fountain side part 4 only rests on the bottom of the guide groove 13 in this area.
  • 6 other adjusting elements can be used instead of the springs, e.g. one or two screws that act on the top of the ink fountain side part 4.
