Definitions

  • the invention relates to an arrangement of a working squeegee on an ink-carrying roller according to the preamble of claim 1.
  • DE 42 13 662 C2 shows a chambered doctor blade, in which the working doctor blade is placed at a negative angle of attack of approx. 40 ° on the outer surface of an ink-guiding roller.
  • the outer surface of this roller is in the form of integrated cup structure.
  • the invention has for its object to provide an inking unit with at least one on a roller with a structured surface squeegee, in which undesired ink deposits of printing ink on the roller facing outer surface of the squeegee white test can be avoided.
  • the object is achieved by the features of claim 1.
  • the advantages that can be achieved with the invention are, in particular, that there is no unwanted ink droplet chenbi Idung on the outside of doctor blades, in particular of Arbe its rake. This avoids that the color droplets from a certain size come loose from the outside of the squeegee and
  • Figure 1 is a cross section through the schematic representation of an inking unit with a Farbdos i e rwa Ize with a structured surface and ink box placed on it with at least one working on it negative squeegee.
  • FIG. 2 shows a front view of the Fa rbdos i erwa Ize according to FIG. 1 in a reduced representation
  • Fig. 3 shows a detail "Z" of Figure 2 in section.
  • FIG. 4 shows a schematic perspective illustration of a screw-shaped arrangement of the grooves located in the lateral surface of the fa rbdos ie rwa Ize; 5 shows a representation analogous to FIG. 4, but with an annular arrangement of the grooves;
  • FIG. 6 shows a representation analogous to FIG. 4, but with an interrupted helical arrangement of the grooves
  • FIG. 7 shows a schematic illustration of an embodiment variant of FIG. 1
  • FIGS. 8 shows a schematically greatly enlarged illustration of an embodiment variant of a color dosage according to FIGS. 2 and 3.
  • An inking unit e.g. B. a short inking unit, a rotary printing press has in its shortest design an ink fountain 2, a Farbdos i erwa Ize 1 and an inking roller.
  • the surface 12 of the color dose 1 is 1 structured.
  • the ink fountain 2 consists of a left and a right side wall 3; 4 and is left and right by a front wall 6; 7 completed.
  • the left side wall 3 carries at the bottom a working squeegee 8, which expects negative to a color dose 1, i. H. is turned against their direction of rotation.
  • the outer working edge 11 of the working squeegee 8 touches the surface 12 or the circumference of the inkjet coating 1.
  • the working squeegee 8 can be made of metal, e.g. B. spring steel, made of plastic, for. B. PE or PMA or from one glass fiber reinforced plastic.
  • Alpha denotes an acute opening angle, which two tangents 13 and 14 intersect at a point A enclose.
  • the second tangent 13 is placed on the outer surface of the working squeegee 8 facing away from the ink fountain 2 and has contact with the contact point A.
  • the opening angle “Alpha” is called the “angle of attack Alpha” of the work rake 8 referred to the ink fountain roller 1 in the work position and is preferably in the range equal to / greater than 10 ° and the same / smaller 35 °.
  • the working squeegee 8 has an inner surface 30 facing the ink fountain and one facing the fa rbdos i e rwa Ize 1, i. H. for the second outer surface 31 facing away from the work box.
  • a closing squeegee 16 is attached at the bottom of the right side wall 4. Your working edge 17 is on the surface 12 of the Fa rbdos ie rwa Ize 1 pressed.
  • the ink fountain 2 with squeegees 8; 16 is arranged above the color dose 1, ie. H. in the 1st or 2nd squares, based on a right-angled coordinate system, the origin of which lies on the axis of rotation 18 of the Fa rbdos i e rwa Ize 1 (FIGS. 1 and 2).
  • the first working squeegee 8 can be followed, as seen in the direction of rotation of the rfbos i e rwa Ize 1, by one or more working squeegees 32 attached to squeegee holders 34 (FIG. 7).
  • the first working squeegee 8 need not be part of an ink fountain 2. Detached from an ink supply, it can scrape off printing ink from an ink dose loaded with printing ink, which is then collected in an ink container 33.
  • FIG. 4 shows a simplified illustration of a multi-coil groove on an ink metering roller 1.
  • the multi-coil grooves 22 extend between the end faces 36; 37 of Fa rbdos i erwa Ize 1.
  • multi-spiral grooves 22 are, as already mentioned, in the surface 12 of the ink metering roller 1 z. B. incorporated all round.
  • the multi-spiral grooves 22 have a pitch angle Beta.
  • the pitch angle beta can be in the range from 0 to 20 ° (FIGS. 2, 4 to 6 and 8).
  • the inclination can be increasing on the right (FIG. 2) or on the left (FIG. 4).
  • the ink metering roller 23 has a plurality of endless ring grooves 24 running around the circumference of its surface.
  • the angle of inclination “gamma” is understood to mean the angle which the surface enclosed by ring grooves 24 forms with a vertical plane with which the axis of rotation 18 of the ring groove 24 (and thus the ink metering roller 1) forms a right angle.
  • the angle of inclination gamma is preferably in a range from 0 ° to 20 °.
  • the ink metering roller 26 has screw-in grooves 27 which are interrupted as often as desired.
  • the ends 28 of the ends 1 to 27 are arranged offset from one another. 6 is not to scale.
  • the printing ink can also have a high viscosity of more than 10 Pa x s.
  • grooves 22; 24; 27 - are each interrupted by one or more transverse webs 38.
  • the ink metering roller 1; 23; 26 has an oleophilic
  • Coat It can be made of ceramic material, e.g. B. Cr 0, from
  • plastic e.g. B. PE or polyamide, from one G las ke rami kwe r ks tof f or consist of a sufficiently hard oleophilic metal or metal alloy.
  • the grooves 22; 24; 27 can completely with a lower layer 41 of oleophilic metal, for. B. copper or plastic, e.g. B. Rilsan filled.
  • the aforementioned cup 39 can also - as shown in Fig. 3, right groove 22 or cup filled - z. B. be filled by means of a layer 41 of copper up to a height d / 2.
