Definitions

  • the invention relates to ink dividers for a flexographic printing press inking unit between two different ink-promoting areas of an inking roller, to which two doctor blades are placed above and below ink storage spaces, which are separated from one another by ink compartment plates.
  • Such a device is known for example from DE-OS 33 20 638.
  • the end faces of the ink compartment plates rest against the jacket of the inking unit roller by spring force for the purpose of sealing.
  • the ink storage space is sealed at the side by the ink compartment sheets bearing against the end faces of the doctor blades or the doctor blades.
  • Such devices have the disadvantage that, on the one hand, adequate sealing of the ink storage space under all operating conditions, especially in the case of low-viscosity printing inks, should only be possible with difficulty and that, on the other hand, no continuous doctor blades can be used, because these must correspond to the number and length of the required color storage spaces must be dimensioned.
  • a color ring remains on the ink roller, which tends to spray off at higher speeds or dries over a longer period of operation.
  • a doctor blade (2) is attached to an inking unit roller (1), for example an anilox roller, by means of which the ink applied from a ink storage space with one ink is doctored off.
  • an inking unit roller (1) for example an anilox roller
  • another doctor blade (3) is preferably placed on the other side of the ink storage space S, by means of which the ink is doctored in the other direction of rotation. If only operation in one direction is required, a doctor blade can also be used instead of the second doctor blade (3).
  • the inking roller (1) can rotate clockwise and counterclockwise in accordance with the double arrow (4).
  • ink wells In order to be able to dye the inking roller (1) in the axial direction with different colors, separate ink wells (5, 6) are required, as can be seen in FIG. Since printing media are often also printed with different colors, the ink wells must be changed accordingly in terms of their axial extent. In the ink splitter device according to the invention, this is possible continuously without the use of notches or depressions on the circumference of the inking roller, it also being possible to use continuous, ie non-subdivided doctor blades (2, 3).
  • the side of an ink compartment separating plate (9) facing an ink storage space is therefore covered with a seal (7).
  • the seal (7) resting on the inking roller (1) is provided with a sliding coating (8) via the associated jacket section M.
  • the color compartment plate (9) can for example consist of a stainless steel plate.
  • the material for the seal (7) is e.g. Rubber or neoprene in question.
  • a suitable sliding surface (8) is e.g. Teflon.
  • the shape of the seal (7) on the ink compartment plate (9) is such that it protrudes and in such a way that it rests elastically with the protruding areas below the doctor blades (2) and (3), ie the seal (7) seen in the direction of rotation of the inking roller (1), before the doctor blade (2) or (3) comes to rest.
  • the protruding part lying on the jacket section M of the inking roller, the curvature of which is adapted to the inking roller (1), is coated with the sliding material (8) in order to protect the inking roller (1).
  • the ink compartment plate (9) according to the invention with the seal (7) thus results in a reliably sealing lateral boundary of an ink storage space S. If, nevertheless, some paint escapes laterally, drainage channels provided on the other side of the ink compartment plate (9) are advantageously formed Recesses (10, 11) ensure that the emerging paint is not dried or thrown off, but is removed via these recesses (10, 11) along the ink compartment plate (9) and fed to an ink collecting device, not shown. It is advantageous to subdivide the individual recesses (10, 11) by means of webs (12, 13).
  • FIG. 4 shows an insert (19) with two seals (15, 16) which are dimensioned in accordance with the seal (7) already described and attached to color compartment plates (21, 22), for example glued on.
  • a subdivision ie an axial limitation, can thus take place at any point on an inking roller (14) with the insert (19).
  • the insert (19) separates two troughs (5, 6) which preferably have different colors.
  • the seals (15, 16) are each provided with a sliding coating (17 or 18) and the color compartment plates (21, 22) have recesses (23, 24), which may also be provided by webs can be separated or divided.
