Definitions

  • the invention relates to a method for printing on printing machines, in particular sheetfed offset printing machines, after a machine stop or at the start of a print job.
  • the invention further relates to a device consisting of a plate cylinder, an impression cylinder and a rubber cylinder, the rubber cylinder having means for adjusting assigned to the printing pressure and for positioning the rubber cylinder on the impression cylinder are.
  • the rubber cylinder is used to turn the plate and impression cylinders on and off stored on both sides in eccentric bushings.
  • These eccentric bushings are one on one Abutment supporting toggle lever mechanism can be swiveled actuating means actuated by the application of pressure medium.
  • the actuating device exists consisting of two parallel, double-acting working cylinders that are fixed to the frame, whose piston rods are articulated to a coupling. The coupling is via a hinge pin connected with a toggle mechanism.
  • the working cylinders are for pressure adjustment one after the other and for printing shutdown both individually one after the other and simultaneously pressurizable.
  • the hinge pin is used to change the pressure provided between the blanket and the impression cylinder, that is, to generate the printing pressure specific to the substrate, via a spindle nut can be pivoted in cooperation with an adjusting spindle.
  • the adjusting spindle is actuated from the outside by a handwheel twisted. Turning the adjusting spindle causes the eccentric bushes to turn what the contact force of the rubber cylinder to the impression cylinder changed.
  • the object of the invention is a method and a device for performing to develop the method by which the contact of the rubber cylinder with the Duplication originating from the impression cylinder is avoided.
  • the invention has the advantage that the positioning of the rubber cylinder on the impression cylinder completed before the first sheet arrived.
  • the mass of the rubber cylinder has already come to rest and that from braking the mass of the rubber cylinder resulting vibrations have already subsided. There is more for printing Time available, so that an exact coloring of the plate cylinder and the blanket cylinder can be secured.
  • an impression cylinder 1 is arranged on which a rubber cylinder 2 is employed. This is in contact with a plate cylinder 3. Both the impression cylinder 1 and the rubber cylinder 2 are provided with channels 11 and 21 arranged parallel to the axis fitted. Grippers 12 are arranged in series in the impression cylinder channel 11 to hold the press sheet.
  • the plate cylinder 3 also has a channel (in the figure not shown).
  • the rubber cylinder 2 and the plate cylinder 3 are mounted eccentrically. It can be spotted, that the rubber cylinder axis 23 is mounted eccentrically to the rubber cylinder bearing 24.
  • the Eccentric, formed by the spatial distance of the rubber cylinder axis 23 from the rubber cylinder bearing 24, is fixed with an adjustment segment 41, which is part of an adjustment mechanism 4 is connected.
  • the adjustment segment 41 has teeth 45 on its outer contour. This toothing 45 engages in the toothing of a gear pinion 42, which in turn also a rack 44 combs.
  • the contact gear pinion 42 / rack 44 is by a roller 43 maintained.
  • the rack 44 is articulated to the piston rod 51 of an adjusting cylinder 5.
  • the adjusting cylinder 5 has a position I for "down” and a position II for "on”. He owns one Piston 54 and is articulated at its articulation point 52 in a frame point 53.
  • the articulation point 52 is connected to the adjusting spindle 61 of an actuator 6.
  • the servomotor 6 is articulated at its articulation point 62 to a frame point 63 and is infinitely variable to the substrate thickness adjustable.
  • the adjusting spindle 61 of the servomotor 6 is connected to the piston rod 71 of a working cylinder 7, which is articulated in a frame point 73.
  • the adjusting cylinder 5 has one position I 'for "down” and a position II' for "on".
  • Cylinders 2 and 3 are at the end of a print job or after a machine stop switched off. That is, the rubber cylinder 2 is out of contact with the impression cylinder 1 and the plate cylinder 3.
  • the system is connected to the substrate to be printed adjusted, whereby here in particular the thickness of the printing material is included.
  • the setting is made based on the prepress data provided for the printing process.
  • the servomotor 6 actuated.
  • the adjusting cylinder 5 is in position I.
  • the working cylinder 7 moves from the position with the arrival of the first printing sheet I 'in position II'. This will make the required compression pressure rubber cylinder 2 / impression cylinder 1 built.
  • the way of the rubber cylinder 2 to realize the Pressure then amounts to a few tenths of a millimeter and does not lead to any dynamic disturbance. When you turn off the pressure, the movement takes place in reverse order.
  • FIG. 2 Another embodiment of the invention can be seen in FIG. 2.
  • a cam mechanism 8 is arranged here.
  • the cam mechanism 8 has a position I 'for "ab” and a position II 'for "an”. It consists of a cam 81, which is a cam roller 82 is assigned.
  • the cam roller 82 is mounted on a roller lever bearing 84 Roller lever 83 attached. By a spring 85 acting on the roller lever, the system of the Cam roller 82 secured to the cam 81.
