Definitions

  • the invention relates to a chambered doctor blade device for a short inking unit of a rotary printing press according to the preamble of claim 1.
  • a chamber doctor blade device for a short inking unit of a rotary printing press which has a ink circulation chamber between a doctor roller and an ink roller, which receives a rotatable roller.
  • the invention has for its object to provide a chamber doctor blade device for a short inking unit of a rotary printing press, in which there is good ink mixing and a uniform distribution of the printing ink on the anilox roller even when circulating little printing ink.
  • the chamber doctor blade device 2 can consist of an ink tray 3 with an approximately U-shaped profile, which extends with a length l below and axially parallel to the anilox roller 1.
  • the length l of the ink fountain 3 can be a quarter of the total length of the anilox roller 1, so that four different ink tanks 3 can be arranged under the anilox roller 1.
  • Each paint tray 3 has end plates 4, 6, which the U-profile on both sides z. B. close with screws.
  • the striking plates 4; 6 are adapted with their side facing the anilox roller 1 to the periphery of the anilox roller 1.
  • both striking plates 4; 6 are in the axis-parallel direction to the anilox roller 1 and inside the chamber doctor device 2 pointing axles 7; 8 attached, on which via ball bearings 9; 11 both ends of a roller, e.g. B. rubber roller 12 is rotatably mounted.
  • the rubber roller 12 has on its jacket 15 elevations 13 which, for. B. can be rhomboidal (shown in detail in Fig. 2).
  • the rubber roller 12 is arranged at such a distance a from the anilox roller 1 that it can be driven by friction when the anilox roller 1 rotates, with a film of printing ink to be transferred to the anilox roller 1 between the anilox roller 1 and the rubber roller 12.
  • the rubber roller 12 can also be separately by a drive unit, not shown, for.
  • At the bottom 14 of the ink tray 3, ie at a short distance from it and at a distance b to the jacket 15 of the rubber roller 12 are several, for. B. two axially parallel driven discs 17; 18 arranged, the drive shafts 19; 21 run at right angles to the axis of rotation 22 and can lead to drives (not shown) located outside the chamber doctor device 2.
  • the drives can e.g. B. flanged outside on the bottom 14 of the ink pan 3.
  • the distance b between the disks 17; 18 to the rubber roller 12 is for each disc 17; 18 individually adjustable. But it is also possible that the distance b of the disks 17; 18 to the rubber roller 12 for both disks 17; 18 is adjustable together.
  • the chambered doctor device 2 has two resilient doctor blades - a working doctor blade 23 and a closing doctor blade 24 - which are arranged at a distance from one another and can be adjusted, which extend in the axis-parallel direction to the anilox roller 1 and in strip-shaped holders 26; 27 are clamped.
  • the holder 26; 27 for the squeegee 23; 24 are form-fitting on both ends with the striking plates 4; 6 of the chamber doctor blade device 2 connected.
  • the drivable disks 17; 18 are expediently circular and can have teeth on their periphery. Furthermore, the disks 17; 18 may be provided with different through holes to z. B.
  • the doctor blade device 2 is by a Known known lifting and lowering device 28 adjustable in height and thus adjustable to the anilox roller 1.
  • a left upper side wall (FIG. 1) of the ink tray 3 is designed to be pivotable, so that printing ink can be filled or refilled into the ink tray 3 when the side wall is pivoted off.
  • the function of the chambered doctor blade device 2 is as follows: during the operating state, i. H. during the rotation of the anilox roller 1, z. B. clockwise (Fig. 1), the rubber roller 12 rotates counterclockwise, with the disks 17; 18 so that in a gap 29 between the two discs 17; 18 a flow of printing ink 20 is conveyed in the direction of the long side of the ink trough 3, which has the closing squeegee 24, so that the rubber roller 12 transports the printing ink back towards the anilox roller 1, and the anilox roller 1 transports the printing ink 20 towards the working squeegee 23.
  • the directions of rotation of the disks 17; 18 and the rubber roller 12 by means of circles with a point, the circle-dot symbol 30 means that this marked part moves out of the plane of the drawing sheet in the direction of the viewer of the drawing.
  • the rubber roller 12 moves in the opposite direction to the anilox roller 1, ie clockwise, so that the anilox roller 1 is located between the working squeegee 23 and the anilox rollers Surface line of the rubber roller 12 forms an ink bead.
  • both disks 17; 18 be designed as meshing gears, which then only need a common drive.
  • FIG. 3 it is possible to place between two disks 17; 18 to arrange a worm shaft 31 which is mounted in the vicinity of the base 14 and inside the paint trough 3 and is driven outside the paint trough 3 and which is connected to both toothed wheels 17; 18 as well as with a toothing 32 located on the circumference of the rubber roller 12.
  • the toothing 32 of the rubber roller 12 is located at the point of half the length l of the ink tray 3 and does not protrude beyond the outer surface 15 of the rubber roller 12. This results in the aforementioned direction of movement of the parts 17; 18; 32 (Fig. 3).
  • the ink tray 3 is arranged vertically under an axis of rotation 16 of the anilox roller 1.
  • a vertical center line 25 of the ink fountain 3, which runs through the axis of rotation 16 of the anilox roller 1 to be pivoted through an angle plus or minus alpha, so that the ink fountain 3 lies laterally against the anilox roller.
  • a second roller not shown, spaced apart at a distance b, which roller co-rotates with the roller 12, i. H. clockwise (Fig. 1).
  • the second roller can be driven synchronously with the drive of the roller 12.
  • the material as well as the surface of the second roller can be designed as described for the roller 12.
  • the second roller can also have a steel jacket.
  • the diameter of the second roller can differ from the diameter of the roller 12. Should the second roller be moved by the roller 12 by means of a friction drive, a smaller diameter of the second roller would be advantageous.
  • the ink tray 3 can be arranged so as to be pivotable by an angle alpha.
  • the angle alpha can be between zero and 45 °.
  • a filling height h of the printing ink 20 can be between a quarter to half the diameter of the roller 12.
