Definitions

  • a device of this type is known from GB-A 888 611. With this device, continuous stroke adjustment is not possible while the machine is running.
  • DE-OS 2 238 481 a drive for a simultaneous rotating and reciprocating distributor roller on printing machines has become known. This drive is based on the task of slowing down the displacement movement with the internal control so that the advantages of the internal control can be used without the disadvantages of a rapid course of the axial movement.
  • the trituration insert is set in the factory in the normal position so that the trituration rollers start to pull when the printing start of the plate cylinder is at the second applicator roller.
  • the use of rubbing is changed for special printed images in which there are large color density differences in the direction of the cylinder axis.
  • the printing press must be switched off in order to be able to adjust the distribution stroke. This means a certain set-up or assembly time and a considerable number of waste sheets before the optimal rubbing stroke required for each print image is set.
  • Waste can also arise during production if it turns out that the rubbing stroke has to be changed by certain parameters of the printing press, e.g. due to the temperature influences during printing.
  • the object of the invention is to achieve a stepless stroke adjustment while the machine is running with minimal waste, depending on the print or printed image and the production run.
  • the device can be used equally in the upper and lower inking units of a printing press.
  • the handle has a scale division, so that the printer can set the scale according to the known printed image for similar print jobs.
  • an automatic remote-controlled friction stroke adjustment can be carried out by means of an electric motor. It is conceivable here to import the correspondingly coded position values onto a tape, which leads to an easy adjustment process for repeat jobs.
  • a swing arm is arranged between a swivel lever and a coupling a sliding joint is pivotally connected to the swivel lever.
  • the stroke adjustment of the distribution rollers within the printing press can thus be changed with minimal machine elements.
  • a wide variety of lifting movements can be adjusted from the handwheel or the motor to the rocker using a fork lever.
  • a handle 15 is arranged on the machine operating side 16 at handle height of the printer.
  • the handle 15 merges into a threaded spindle 9, which enables a threaded guide pin 8 to be adjusted in the axial direction of the threaded spindle 9 by turning the handle 15.
  • the thread guide pin 8 is guided in a groove 7.1 of a two-armed fork lever 7.
  • a hinge pin 5 is rotatably fastened within a rocker 5.1.
  • the rocker 5.1 has a groove 5.2 in which a slide joint 5.4 is guided.
  • a hinge pin 3.2 is attached to the rocker 5.1, on which a coupling 3.1 engages.
  • the coupling 3.1 is articulated to a crank shaft 3.3 which is fastened to a printing machine shaft 3.
  • the printing machine shaft 3 provides the drive for the axial back and forth movement of the distributor rollers 1 via the above-mentioned machine elements (3-11).
  • a sliding block 5.3 is slidably mounted, which is attached to a bolt 6.2.
  • the bolt 6.2 is fixedly attached to a swivel lever 6.1.
  • the pivot lever 6.1 rotates about a pivot point 6, which is fastened in a machine side stand, here a holding plate 18.
  • the pivot lever 6.1 and the rocker 5.1 execute parallel pivoting movements.
  • the pivot lever 6.1 is connected on its second side via a driving element 11 to the friction levers 10.1-10.3.
  • the friction levers 10.1-10.3 are fixed to a fulcrum 10 within the printing press 4.
  • the rubbing levers 10.1-10.3 transmit the axial lifting movement to the rubbing rollers 1 by their rotary movement.
  • the rubbing levers 10.2 and 10.3 are respectively arranged on opposite ends of the rubbing rollers 1.
  • FIG. 2 shows the same technical structure as described in Fig. 1, but instead of the handle 15, an electrically controllable motor 17 acts on the threaded spindle 9.
  • Figure 3 shows a partial section of the printing press 4, with the stroke adjustment by the handle 15.
  • the threaded spindle 9 is arranged in the axial direction on the handle 15, on which the threaded guide pin 8 is located.
  • the threaded guide pin 8 can be changed axially on the threaded spindle 9.
  • This axial stroke movement of the threaded guide pin 8 is transferred to the fork lever 7, the threaded guide pin 8 being positively guided in the groove 7.1.
  • the hinge pin 5 On the second lever arm 7.2 of the fork lever 7, the hinge pin 5 is fastened within the rocker 5.1.
  • the drive for the distributor rollers 1 takes place via the coupling 3.1 on the rocker 5.1.
  • the slide joint 5.4 is designed in the form of a sliding block 5.3.
  • the pivot lever 6.1 executes a rotating back and forth movement about the pivot point 6.
  • the size of the back and forth movement of the pivot lever 6.1 depends on the adjustment size of the fork lever 7.
  • the pivot movement of the pivot lever 6.1 about the pivot point 6 is transmitted to a driving element 11 on the side of the pivot lever 6.1 opposite the pivot point 6, the driving element 11 being rotatable is mounted in a shoulder bearing 20 in the pivot lever 6.1.
  • the entrainment element 11 transmits the movements to a first lever 21 of the friction lever 10.3, which is fixed in the fulcrum 10 within the printing press 4.
  • a second lever 22 of the distribution lever 10.3 acts on the distribution rollers 1 and, depending on the setting on the handle 15, leads to a differently large stroke 2 of the distribution rollers 1.
