Definitions

  • the invention relates to a traversing drive for the friction rollers of at least one inking unit of a printing unit of an offset rotary printing press, in which a separate eccentric drive which is adjustable in the traversing stroke is arranged one behind the other on a common drive axis and which is arranged in rhythm with the rotating eccentrics in the axial direction of the friction rollers reciprocating eccentric movements can be transmitted to the stub axles of the friction rollers via coupling elements.
  • Such a traversing drive is known from US-A-1 741 414.
  • the disadvantage is that the friction rollers receive their drive for the lateral traversing movement from a complex separate drive and no adjustment of the phase position of the traversing movement, i.e. between the rubbing and the rotation of the plate cylinder.
  • a traversing drive is also already known from EP-A-0 066 114, in which a common eccentric drive which is adjustable in the traversing stroke is arranged for two inking units of a four-cylinder printing unit, the movement of which is derived from an inking unit drive.
  • the disadvantage is that the type of coupling means that a separate, central adjustment of the lateral oscillating movement in the inking units is no longer possible. This leads to difficulties in particular when, in addition to a separate central adjustment of the traversing stroke, an adjustment of the phase position of the traversing movement is also required in order to be able to adjust the color areas or color films to be rubbed to meet the separate requirements in both inking units.
  • Another disadvantage is that the common eccentric drive requires a reduction gear that has a drive gear, which must be driven by the machine via a disengageable gear.
  • the invention has for its object to provide a traversing drive of the type mentioned, in which the lateral traversing movement of a set of friction rollers for at least two inking units of a printing unit can be derived together in a central arrangement from an existing machine shaft, but separately in the traversing stroke and the phase position of the traversing movement , preferably independently adjustable.
  • the traversing movement is reduced in the stroke number 1: 2 in a simple manner, which simplifies the drive conditions .
  • the assignment of a separate eccentric drive to each set of friction rollers, the traversing stroke and the phase position of the traversing movement preferably can be set independently of one another, whereby a uniformity of the ink layers or ink films that meets the separate requirements of at least two inking units can be achieved.
  • the central space-saving arrangement of the traversing drive also makes it easier to adjust the machine.
  • FIG. 1 shows a five-cylinder printing unit which comprises two blanket cylinders 2, 3, two plate cylinders 4, 5 and a printing cylinder 1 which is twice as large.
  • Each of the plate cylinders 4, 5 is assigned an inking unit 6, 7 and a dampening unit, not shown.
  • an eccentric drive 18, 22 for the inking unit 6, which is separately adjustable in the phase position of the traversing movement and in the traversing stroke, and the eccentric drive 19, 22 for the inking unit 7 are connected to the cylinder end of the printing cylinder 1.
  • Figures 1 and 2 show that the eccentric drives of the inking units 6.7 have a disk 18 and 19, each with an elongated hole, which are radially displaceable and rotatable in the circumferential direction are connected to the end of the printing cylinder 1 via a bolt 22.
  • eccentric movements for both inking units 6, 7 are reduced in the axial direction of the friction rollers 8, 9 together at half-speed to rotate the associated plate cylinder 4, 5 from the common drive axis of the printing cylinder 1 via spherical bearings 20 , 21, rocker arms 16, 17, control levers 14, 15 and rocker arms 12, 13 are derived, the latter being attached to the machine side frame by means of journals 11 in bearings (not shown).
  • the rocker arms 12, 13 are only shown for part of the friction rollers 8, 9 of the inking units 6, 7 in FIG. 1.
  • FIG. 2 allows the traversing stroke and the phase position of the traversing movement to be adjusted separately for each inking unit
  • the embodiment according to FIG. 3 allows the adjustment to be carried out independently of one another and separately for each inking unit.
  • an eccentric drive 23, 25 for the inking unit 6 is ring-shaped is arranged concentrically above a second eccentric drive 24, 26 of the inking unit 7 and both are connected to the end of the printing cylinder 1.
  • a disk 23 can be rotated in T-grooves 27 on the pressure cylinder 1 and fixed with bolts 29.
  • the disk 23 also accommodates a disk 25 in grooves 31, which can be moved radially and can be fixed via bolts 28, on which the rocker arm 16 of the eccentric drive 23, 25 of the inking unit 6 is arranged via bearings 32.
  • the eccentric drive 24, 26 of the inking unit 7 has a disk 24 with an elongated hole, which is rotatably connected in T-slots 33 to the end of the printing cylinder 1 by means of bolts 30.
  • a bolt 26 is also arranged radially displaceably for adjusting the traversing stroke.
  • the rocker arm 17 is received on the pivot bearing 34 on the bolt 26.
  • the setting of the traversing stroke and the phase position of the traversing movement for both inking units separately and preferably independently of one another is not limited to the designs shown.
