Definitions

  • the invention relates to a short inking unit of a printing press.
  • Each form cylinder has two pressure surfaces and each pressure surface of the forme cylinder is its own short inking unit, consisting of inking roller, anilox roller and ink fountain, assigned.
  • the inking rollers are alternately on and off the forme cylinder Ab niethol, coloring only the respective associated printing surface, arranged.
  • the object of the invention is to provide one of an anilox roller, a clockwise to a Printing forme cylinder on and off inking roller and a color box existing Short inking unit with high rigidity of the anilox roller bearing.
  • the Ink application roller 2 is by means of a cyclically actuated Taktexzenters 3 intermittently to the Printing form cylinder 1 adjustable or off this.
  • the inking roller 2 associated with anilox roller 4 is a three-ring bearing. 5 in the machine frame 6 - indicated in the drawing with slashes - stored.
  • the inner ring of the three-ring bearing is designed as an eccentric bearing 7 and the eccentric is a Shift lever 8 is arranged.
  • the eccentric bearing 7 by means of the shift lever 8 is rotatable.
  • On the shift lever 8 a toggle mechanism 9 is arranged with a spring 10.
  • the spring 10 whose force acts on the articulation point 11 and the eccentric bearing 7 reinforced on the anilox roller 4.
  • the inking roller 2 and the anilox roller 4 are arranged Schmitzringe.
  • the position changes of the inking roller 2 arise because the clock movements are not take place as a rotational movement about the anilox center and it to axle distance changes between inking roller 2 and anilox roller 4 comes. These axle distance changes cause visible variations in the color guide, unless, as stated, be compensated.
  • the inking roller 2 is an operative with an ink fountain, not shown Anilox roller 4 assigned.
  • the inking roller 2 is a three-ring bearing 5 in the machine frame 6 - in the Drawing indicated by slashes - stored.
  • the inner ring of the three-ring bearing is designed as an eccentric bearing 7 and the eccentric bearing a shift lever 8 is arranged.
  • the eccentric bearing 7 by means of the shift lever 8 is rotatable.
  • the movement initiation of the rotation takes place via an unillustrated, on the shift lever 8 arranged cam roller 18, which is arranged with a, not shown, on the printing form cylinder 1 Cam is in operative connection.
  • the arrival and Abstellterrorism the inking roller 2 takes place about a pivot point 12th (Fig. 3).
  • the pivot point 12 lies on a straight line 13, which through the center position 14 of the pivoting path, which is located between the inking roller center 15 at employee and parked inking roller 2 formed, and the anilox center 16 leads.
  • a first variant of the pivot point 12 is located on the line 13 between the anilox center 16 and the center position 14.
  • a second variant lies the pivot point 12 on the extension of the straight line 13 behind the center position 14.
  • Die Pivoting movement of the inking roller takes place about the pivot angle ⁇ , wherein the straight line 13 is within the swing angle.
  • the third embodiment ( Figure 4) shows a four-ring inking roller.
  • the inking roller 2 is an operative connection.
  • the inking roller 2 is an operative with an ink fountain, not shown Anilox roller 4 assigned.
  • the anilox roller 4 is mounted in ball bearings, not shown.
  • the inking roller 2 is a four-ring bearing 17 in the machine frame 6 - in the drawing indicated by slashes - stored.
  • the first inner ring of the four-ring bearing 17 is formed as an eccentric bearing 7 and the eccentric bearing 7, a shift lever 8 is arranged.
  • the eccentric bearing 7 by means of the shift lever 8 is rotatable.
  • the shift lever 8 is supported via a cam roller 18 arranged on a printing forme cylinder 1 Clock curve 19 from. With the shift lever 8 are clock springs 20 in operative connection.
  • the shift lever 8 is equipped with a locking device 21, with the locking device the blocking of the clock movement can be initiated.
  • the further inner ring of the four-ring bearing 17 is formed as a further eccentric bearing 22 and at the other eccentric bearing 22, a further shift lever 23 is arranged.
  • a further shift lever 23 is arranged to the gap setting between inking roller 2 and anilox roller 4 -.
  • the cleavage inking roller / anilox roller must be disconnected during print interruptions; in printing mode is the Ink application roller 2 with the anilox roller 4 in operative connection - is the other eccentric 22 by means of the further shift lever 23 rotatable.
  • a toggle mechanism 9 is arranged with a further spring 25.
  • the toggle mechanism 24 is actuated via an actuating mechanism, not shown, for example via a pneumatic cylinder.
  • the gap setting - inking roller 2 and anilox roller 4 in operative connection - the other spring 25 is stretched over the toggle mechanism 24 whose force acts on the pivot point 26 and the other eccentric 22 reinforced on the inking roller 2.
  • the inking roller 2 is based on the spring force driven against the anilox roller 4; the pressure between inking roller and anilox roller remains constant.
  • On the ball ends of the inking roller 2 and the anilox roller 4 Schmitzringe are arranged.
