Definitions

  • the invention relates to a doctor device for a flushing inking unit of a rotary printing press, consisting of a doctor blade carrier, on which two doctor blades can be attached, approximately roof-shaped and parallel to each other, which can be adjusted to an inking roller and which, together with the inking roller, doctor blade carrier and sealing means provided on the end, delimit an ink chamber. from lines for supplying and discharging ink into and out of the ink chamber, and from adjusting devices for pressing the doctor blade carrier onto the ink application roller.
  • Doctor devices of this type are known for example from DE-40 01 733 A1 and DE-40 01 734 A1.
  • the object of the invention is to provide a doctor device of the type mentioned, in which the same pressure of both doctor blades on the anilox roller is ensured with high accuracy.
  • this object is achieved in a doctor blade device of the type specified at the outset in that the doctor blade carrier is connected to a doctor blade carrier which is provided with the coupling rods of parallel linkage systems, and in that the parallel linkage arms are articulated on the inking unit stands or on supports of the inking unit units. Since the doctor blade carrier is carried by the coupling rods of parallel link systems, it remains parallel to itself during its positioning movement against the anilox roller, so that an undesirable, uneven pressure of the doctor blade on the anilox roller can be avoided. Although the height of the parallelogram of the parallel linkage system changes with a positioning movement, this change is negligibly small, especially when the handlebars form an angle of approximately 90 degrees with the coupling, and can be taken into account when designing the parallel linkage system. A change of path also occurs basically only through the abrasion of the doctor knife edges, which must be kept low anyway.
  • Each coupling rod is expediently connected in an articulated manner to the piston rod of a pneumatic cylinder which effects the pressure and which is articulated to one of the inking units or the carrier of the inking units.
  • the parallel links on one side of the parallel link systems are provided with a device which displaces the articulation axis.
  • the displacement device expediently consists of an eccentric.
  • the bearing can therefore contain an eccentric shaft, the rotation of which can raise or lower the joint axis.
  • the pneumatic cylinders causing the pressure are differential piston cylinders, the cylinder space through which the piston rod is passed also being pressurized.
  • the two cylinder chambers are pressurized in such a way that the pneumatic cylinders press the doctor blade carrier onto the anilox roller with the desired force.
  • This pressure can already be brought about by applying the same pressure to both chambers, in which case a greater pressure is then brought about from the rod chamber-free cylinder chamber due to the larger piston area. Since the cylinder chamber penetrated by the piston rod is also pressurized, undesirable blows of the doctor blade against the anilox roller are avoided because the latter is pressurized by the second cylinder chamber be absorbed resiliently and damping.
  • One side of the anilox roller 2 is mounted in the inking unit 1, which is displaceably mounted in the usual manner on the printing cylinder block, which is also designed as a slide, in the usual and therefore not described in detail.
  • the parallel links 5, 6 are pivotally mounted about the articulation axes 3, 4.
  • the upper ends of the parallel links 5, 6 are pivotally connected to the carrier 9 forming a coupling about the hinge axes 7, 8.
  • the carrier 9 is formed in one piece with the doctor carrier 10.
  • Doctor blade carrier 10 is connected to doctor blade carrier 11 by screws provided with handwheels 11.
  • the piston rod 12 of a pneumatic cylinder 13 is articulated to the carrier 9 or to the upper ends of the parallel link 6, which in turn is articulated to the inking unit 1 by a joint 14 through the articulation 15.
  • the hinge axes 4 of the parallel link 6 are provided with an eccentric adjustment 4 ', on the basis of which the pivot axis of the parallel link 6 can be raised and lowered.
  • the parallel links 5, 6 of each of the two anilox rollers 2 supporting the anilox roller 2 can be designed to increase the stability.
  • the doctor blade carrier 11 consists of a profile strip, the profile of which can be seen in FIG. 1.
  • the bar of the doctor blade carrier 1 is provided with a channel 20 forming the interior of the ink chamber. 3, a bore 21 feeding the printing ink opens into this gutter in the lower middle region. In the lower end regions, the gutter is cut through the bores 22, 23 which discharge the printing ink. Vent holes 24, 25 open into the upper end regions of the channel.
  • the end faces 26, 27 of the gutter edges are chamfered in opposite directions.
  • the doctor blades 30, 31 are fastened on these end faces 26, 27 by clamping brackets 28, 29 in the usual and therefore not described in detail.
  • Seals 33, 34 are arranged on the sides of the doctor blade carrier 11 and seal the ink chamber interior 20 from the anilox roller 2. To hold these seals, covers 35, 36 are screwed to the lateral end faces of the bar of the doctor blade carrier.
  • the ink chamber interior is provided on its sides with chambers 38, 39 which are approximately L-shaped in cross section. These chambers are partitioned from the central part of the interior of the ink chamber by intermediate walls 40, 41, the edges of which point towards the anilox roller 2 and have circularly curved gaps 42, 43. Starting from the edges 42, 43, curved wall parts 44, 45 merge into the central main part of the interior of the ink chamber.
  • the lateral chambers 38, 39 are connected to the central part of the interior of the ink chamber by the restricting gaps 42, 43.
  • the wall parts 40, 41 thus form, as it were, weirs through which the ink introduced into the central part of the interior of the ink chamber through the supply bore 21 enters the unpressurized side chambers 38, 39 with a reduction in pressure.
  • the ventilation bores 24, 25 open into them.
  • the outer sides of the walls 40, 41 are provided with coverings 48, 49 made of plastic, which slightly project beyond the edges delimiting the gaps 42, 43, so that metallic contact of the edges with the anilox roller 2 is excluded.
