Definitions

  • the invention relates to a doctoring chamber carrier according to the preamble of claim 1.
  • Such doctor chamber carriers for supporting a colorable doctor blade which can be set against an anilox roller of an inking unit of a rotary printing press are known.
  • a doctor chamber carrier comprises a carrying device with a plurality of support elements, on which the ink chamber doctor blade rests.
  • the doctor chamber carrier comprises actuators, which are connected to the anvil bearing bearing blocks. With these actuators, the carrying device, together with the ink chamber doctor blade, can be moved in the direction of the anilox roller and away from it, in most cases in the radial direction. In this way, the ink chamber doctor blade is switched on and off the anilox roller.
  • actuators are for example in the DE 195 16 224 C2 shown.
  • the actuators shown there are designed as a parallelogram, so that the ink chamber doctor blade can be moved almost in the radial direction of the anilox roller.
  • the carrying device is pivotable about its own axis, so that the ink chamber doctor blade can be brought into a horizontal position .in which the opening points upwards.
  • doctor chamber carriers have hand screws, which act on the doctor chamber and these clamped on the support elements. After loosening the screws, the doctor chamber for cleaning or other maintenance or repair of the support elements can be lifted or deported.
  • the EP 0 359 959 A2 shows a squeegee unit for printing presses with at least one engageable with an anilox roller chamber doctor blade.
  • the chambered doctor blade 1 is fixedly connected to an end plate of a carrier, designated overall by 4, which has (support) two clamping strips, which in turn comprise pins.
  • a hand lever By actuating a hand lever, a force is exerted on the clamping strips by a tensioning element and the holding lugs of a holder are moved around the pins, thus reversibly fixing the doctoring chamber.
  • the DE 94 21 498 U1 shows a holding device for a cooperating with an anilox roller chamber doctor blade of a rotary printing press.
  • the chambered doctor blade 1 consists of a base body.
  • To hire the chambered blade lever arms are provided which move a control shaft.
  • the actuator shaft moves the chamber blade to or from the anilox roller using plungers and compression springs.
  • Both the EP 0 359 959 A2 as well as the DE 94 21 498 U1 show fastening means for the doctoring chambers, which comprise at least one power supply device which extends substantially in the axial direction of the anilox roller.
  • the object of the present invention is therefore to propose a doctor chamber carrier from which the doctor chamber can be detached more easily and more quickly.
  • the power transmission device at least a part of the force provided by the power supply device to the force Squeegee transferable.
  • This power transmission device can divert or pass the force so that, for example, the doctor chamber is clamped by the example of the clamping by screws.
  • a spring element exerts a force on one end of the lever, which counteracts the force exerted by the power supply device force.
  • FIGS. 1 and 3 show a doctor device 1, which acts on the anilox roller 2.
  • the ink present in the doctoring chamber 3 is taken over by the anilox roller 2. Excess paint is stripped by the doctor blades 4 from the surface of the anilox roller.
  • the doctor blade 4 are fixed in a manner not described in more detail with the doctor blade clamping devices 5 on the doctoring chamber 3.
  • the doctoring chamber 3 On the rear side, the doctoring chamber 3 has a plurality of pins 6, which feet 11 carry in the form of a frusto-conical extension.
  • the doctor chamber 3 is located with its rear side on a plurality of support plates 7, wherein the pins 6 pass through the introduced into the support plates 7 incisions.
  • the support plate 7 is fixed at right angles to supports 8, which in turn are secured to the trusses 9.
  • the traverse 9 is pivotable in the direction / of the double arrow A about the axis 10, wherein the traverse 9 is mounted in a known per se manner in a device over which the complete doctor device 1 on the anilox roller 2 on and off again.
  • a rod 14 is rotatably supported by bearings 13.
  • the rod 14 can be rotated by operating the hand lever 15.
  • the cylindrical part of the surface of the rod 14 presses the lever 17 via a pressure piece 16 in the direction of the support plate 7.
  • the lever 17 abuts due to the contour shown only at the support point 18 on the support plate 7 results at the other end of the lever a force in the opposite direction, namely pointing away from the support plate 7.
  • This end of the lever 17 includes the pin 6 and transmits the force on the foot 11, so that the doctor chamber is held firmly on the support plate 7.
  • the pin 6 of the comprehensive part of the lever 17 may be a notch-like recess with chamfers, which are adapted to the contour of the foot 11. In this way, the position of the doctor chamber 3 relative to the support plate 7 is reproducible.
  • the Fig. 2 shows the doctor device 1 in a parked and pivoted away from the anilox roller 2 position.
  • the hand lever 15 is in one Position shown in the flattening of the pressure piece 16 shows.
  • the rod 14 now exerts no more force on the pressure piece 16 and thus on the lever 17. Due to a spring element, not shown, the long arm of the lever 17 is pressed onto the supporting piece, so that the lever 17 lifts completely from the foot 11.
  • the doctor chamber is no longer held on the support plate 7 and can be deported in the direction of arrow B from the support plates 7.
  • the Fig. 3 shows a plan view of the doctor device 1 in her employed at the anilox roller 2 position. From this figure, the already mentioned in the description cuts in the support plate 7 and in the lever 17 can be seen, in which the pin 6 can be inserted.
