Definitions

  • the invention relates to a distributor roller drive on the inking unit of offset rotary printing presses with a series arrangement of the printing units, in which two blanket cylinders cooperate and two plate cylinders are provided, each of which is supplied by an inking unit, with several inking rollers moving laterally to and fro in each inking unit and the drives for the back and forth movement are each via an eccentric drive and push rods.
  • the object of the invention is to provide a distributor roller drive on the inking unit of offset rotary printing presses which is simple and therefore inexpensive in its structure and in its use.
  • the object is achieved with the features of the characterizing part of claim 1.
  • the advantage of the embodiment of the distributor roller drive according to the invention is that only one eccentric drive is required for both inking units per printing unit. This eliminates the otherwise required gear parts and their storage. Furthermore, the roller stroke of all distribution rollers in both inking units can be adjusted centrally on an eccentric drive, so that the adjustment work on the machine is made considerably easier. It is also only necessary at one point for each printing unit to disengage a drive spur gear and thus stop the reciprocating movement of the entire distribution roller drive in both inking units.
  • the subclaims contain advantageous refinements of the subject matter of the invention and, with simple means, enable a high level of operational safety and reliability of the distributor roller drive, the staggered arrangement of the control lever to the connecting rod also causing the drive forces for the lateral back and forth movement to be shifted in time, so that the entire machine drive is relieved becomes.
  • the printing unit of an offset rotary printing machine shown in Fig. 1 consists of the two rubber cylinders 1 and 2, of which the paper web 3 is printed on both sides.
  • the plate cylinders 4 and 5 work together with the rubber cylinders, each of which is assigned an inking unit 6 and 7.
  • the dampening systems also present are not shown for the sake of clarity.
  • Each inking unit consists of a plurality of inking rollers 8 and distribution rollers 9 and 10.
  • Each distribution roller carries out a back and forth movement in the axial direction, the stroke length of which can be set differently.
  • rocker arms 11, 12 are used, which are supported on the machine side frame 15 by means of journals 13 and 14.
  • the rocker arms 11, 12 are moved via control levers 16, 17 and an eccentric drive 18 and thus the friction rollers are moved back and forth.
  • the drive for the back and forth movement of the distributor rollers of the upper inking unit 6 is coupled to the drive of the lower inking unit 7 via additional control levers 19, 20 and a connecting rod 21.
  • the control lever 16 is offset from the connecting rod by about 900, so that the driving forces for the lateral rubbing of the upper and lower inking units act out of phase and thus relieve the drive.
  • Fig. 2 shows that the connecting rod 21 is adjustable in its length via thread 22 and coupled to the control levers 19, 20 via spherical plain bearings 23 is.
  • the control lever 20 is also rotatably mounted on the pin 24 of a bearing body 25, which in turn is attached to the machine side frame 15.
  • the eccentric drive 18 has a drive wheel 26 which is driven by the machine via a disengageable intermediate wheel 27.
  • a slot 28 is provided in an eccentrically offset manner, in which a bolt 29 is slidably provided and can be clamped via a nut 30. With this, the stroke of the rubbing rollers can be adjusted in a simple manner by more or less large eccentricity of the bolt 29.
  • the drive wheel 26 is also mounted on the machine side frame 15 via a wheel journal 31 and a bearing body 32.
