Definitions

  • the invention relates to a drive for an oscillating doctor device according to the preamble of claim 1.
  • a mechanical squeegee drive (DE 32 47 679 A1) is known in which the traversing movement is driven by a circumferentially driven groove with a circumferential groove which is axially deflected relative to a radial plane and into which a sliding block of a sleeve connected to the squeegee slide and secured against rotation engages. equipped spindle is generated.
  • the mechanical squeegee drive is at risk of wear due to the sliding connection and is inevitably subject to wear-dependent play, which has a negative effect on the squeegee process, particularly in the reversal points of the squeegee, due to its prolonged standstill.
  • the reversal points are always in the same place, which promotes both increased squeegee wear and scoring on the roller to be inked.
  • the squeegee drive takes place via a shaft on which two clutches with counter-rotating drive wheels are fastened, which can be alternately coupled with a drive wheel, the direction of rotation of the drive wheels being opposite.
  • the shaft has a transport thread at its other end, which is connected to a squeegee holder via a coupling bush.
  • pages 362 and 363 of the book mentioned also describe a hydraulic drive for the squeegee movement, in which the squeegee beam is coupled to a hydraulic cylinder.
  • the reversal of the direction of the doctor blade movement is effected by a valve connected by two probes connected to the doctor blade beam.
  • the invention has for its object to provide a drive for an oscillating doctor device according to the preamble of claim 1, which largely a constant doctor movement in the entire stroke range, a change of direction with minimal standstill and a continuous adjustment of the speed - possibly depending on the machine speed - as well as a reversal point shift of the squeegee movement.
  • the invention ensures a constant shifting of the reversal point for the squeegee movement, particularly with relatively little effort, so that local squeegee wear and damage to the surface of the anilox roller in the form of grooves are avoided in connection with the virtually non-stop reversal of direction. which increases the service life of doctor and anilox rollers in a cost-saving manner.
  • the cycle time of the computer which is itself disadvantageous for control processes, can advantageously be used for an additional shifting of the reversal points of the squeegee movement.
  • a hydraulic servo valve is particularly suitable for controlling the working cylinder, since it enables particularly low traversing speeds to be implemented reliably.
  • the squeegee carrier 1 has an anti-rotation device 6 and holder 7 guided in the frame 5; 8 for a doctor blade holder 10 which can be pivoted to the anilox roller relative to the doctor blade carrier 1 with the aid of a pressure medium-operated working cylinder 9.
  • the doctor blade carrier 1 is provided with a position sensor 11 for two sensors 13 fixed to the frame and connected to a computer 12; 14 equipped.
  • the computer 12 is connected to a control unit 15 for one in the pressure medium lines 16; 17 coupled for the working cylinder 3 intermediate servo valve 18.
  • FIG. 2 shows a schematic representation of a solution designed according to FIG. 1, in which the doctor blade carrier in the form of a traversing shaft 19 is displaceable in bearings 21 fastened on a cross member 20; 22 mounted and the working cylinder 3 with its piston rod 2 coaxially aligned to the traversing shaft 19 via the coupling 4 with the latter firmly attached to the cross member 20, the coupling 4 consisting of two separately fastened on the piston rod 2 and the traversing shaft 19, axially driver disks 23 screwed together; 24 exists.
  • an elastically deformable disk 25 can also be arranged.
  • a lever 26 is fastened thereon, which carries an axle pin 28 which engages in a sliding seat 27 connected to the bearing 22 for the traversing shaft 19.
  • the cross member 20 between the frame walls 29; 30 of the frame is firmly screwed to it, it can also be used as a cross member between two serving to pivot the entire doctor device from the anilox roller, each pivotable in the frame walls 29; 30 mounted holders can be arranged.
  • the computer 12 which can also be integrated into a printing unit computer, for example, has the traversing speed v as an adjustable input variable, which may also be linked to the machine speed, and the control unit 15 connected to the computer, in addition to the traversing speed v, has the time t as output variables for the servo valve 18 , since within the by the sensors 13; 14 limited stroke range H from the working cylinder 3 to the direction reversal by the respective sensor 13; 14 partial stroke ranges T, which are continuously displaced in the same direction, including the associated reverse traversing movement T c shortened by the offset T v , are permanently programmed in the computer (FIG. 3). This means that with an increase in the traversing speed and thus the lifting speed of the working cylinder, the time for the latter to be pressurized is inevitably shortened.
  • a technically more complex control of the doctor carrier movement is instead of the sensors 13; 14 in Fig. 1 a dash-dotted, the computer over the entire stroke range H of the working cylinder 3 path impulses 31 to arrange, whereby the sub-areas T 1 to T 6 , including the associated retrograde traversing movements T c1 to T c5 , according to FIG. 5 different can be designed.
