Definitions

  • the invention relates to a roller for an inking unit of printing presses with a roller shaft mounted in a rotationally fixed manner in bearings and a roller shell which is rotatably mounted on the roller axis and is driven in such a way that an axial stroke movement occurs via drive means which are provided within the roller shell the rotating roller jacket is transmitted.
  • DE-OS 22 38 481 shows a drive for a simultaneously rotating and reciprocating distributor roller on printing machines.
  • a planetary gear mechanism is used here as the drive means, which in conjunction with a control cam generates an axial stroke movement of the roller shell.
  • the reduction gear shown here has a maximum reduction of 1: 4, so that a stroke of, for example, 15 mm is carried out at four revolutions of the roller.
  • a rocker is provided as the drive means, which carries out a pendulum movement transversely to the longitudinal axis of the roller via an eccentric driven by the roller shell, that the pendulum movement is then transmitted via a freewheel as a rotary movement to a curve, which axially shifts the roller shell during its rotational movement.
  • these drive means for the axial movement e.g. a reduction possible, in which a lifting movement of the roller is carried out at 31.4 revolutions. In this case, approximately one rubbing movement per second is carried out at 40,000 cylinder revolutions per hour, so that the driving forces and thus the wear can be very low and as a result no vibrations are transmitted to the load-bearing parts of the machine.
  • robust components can continue to be used, so that trouble-free operation is ensured and the precision of the printing process can be increased by the absence of vibrations.
  • This configuration of the roller is characterized in that the rocker is pivotally mounted on a bearing pin which is arranged in a non-rotating bearing body fixed on the roller axis, that the rocker carries two diametrically opposed ball bearings, the axes of which run parallel to the roller axis, which on an eccentrically arranged to the roll axis in the roll shell and rotating with this, acting as an eccentric rolling surface and from this a pendulum movement is transmitted to the rocker and that the pendulum movement is transmitted from the rocker via a connecting pin to a rotatably mounted rotating body which interacts with a freewheel, in such a way that the pulsed rotary movements generated in one direction of rotation are one on the roll axis Drive a non-rotatably supported curve with an axial stroke, in which cam rollers are provided, which transmit the stroke to the roller shell via a bearing body and a ball bearing.
  • the roller 1 shown in Fig. 1 is mounted on a roller axis 2, which is rotatably fixed in bearings 3, these e.g. can be arranged on a machine side frame, not shown.
  • the roll shell 4 of the roll 1 is rotatably and longitudinally displaceably supported on the roll axis 2 by means of bearing holders 5, 6 and needle bearings 7.
  • the roller shell 4 in the embodiment shown can be driven by friction from an adjacent roller or a cylinder.
  • a rocker 8 is provided within the latter, which is mounted on a bearing pin 9 in an oscillating manner.
  • the bearing pin 9 is arranged in a non-rotating bearing body 10 which is fastened on the roller axis 2 and which can be jammed, for example, on the roller axis.
  • the rocker 8 is on via needle bearings 11 the bearing pin 9 stored.
  • two ball bearings 12 are mounted on bolts 13, the axes of which run parallel to the roller axis 2.
  • the two ball bearings 12 roll in an eccentric 14 which consists of a rolling surface 15 arranged eccentrically to the roller axis 2, which in the exemplary embodiment shown is provided on a sleeve-shaped extension 16 of the bearing holder 5 and which rotates together with the roller shell 4.
  • the pendulum movement is, for example, 2 mm if the eccentricity of the rolling surface 15 is 1 mm.
  • the two ball bearings 12 roll off the rolling surface 15 almost without play and move the rocker 8 back and forth oscillating around the bearing pin 9.
  • a connecting pin 17 is fastened in the rocker 8 opposite the bearing pin 9 and engages in a rotating body 18 rotatably mounted on the roller axis 2.
  • the rotating body 18 is rotatably supported by needle bearings 19 and secured against axial movement.
  • a freewheel 20 is provided, which is designed as a sleeve freewheel and has roller bearings 20a on both sides and which transmits the rotational movement in a direction of rotation, which is transmitted from the rocker 8 to the rotating body 18, in a pulse-like manner on a curve 21, which the freewheel 20 includes.
  • the curve 21 is also rotatably mounted on the roller axis 2 via needle bearings 22. Together with the rotating body 18, the curve 21 is axially fixed via locking rings 23.
  • the cam track 24 can be designed as a sine curve with a stroke of 15 mm, for example.
  • Two cam rollers 25 move in the cam track 24 and are given an axial movement by the shape of the cam.
  • the two cam rollers 25 are attached to the arm 26 of a bearing body 27, which in turn is mounted on the roller axis 2 so as to be longitudinally displaceable via bushings 28.
  • a ball bearing 29 is provided, which transmits the lifting movement from the bearing body 27 to the roller shell 4.
  • the bearing body 27 is secured against rotation by a fork piece 30 with respect to the roller axis 2, the fork piece 30 permitting the longitudinal movement of the bearing body 27.
  • the rocker 8 Due to the eccentric design of the rolling surface 15, the rocker 8 is set in a sinusoidal oscillating movement by approximately 2 mm, so that the rotational movement transmitted to the rotating body 18 takes place very slowly and smoothly. Due to the likewise sinusoidal curved path 24, the further transmission of the movement to the roller jacket 4 is completely shock-free, so that the latter performs a very quiet reciprocating movement.
  • the eccentricity of the rolling surface 15 and the stroke of the cam track 24 can be adapted to the respective requirements.
