Definitions

  • the invention relates to a printing press, preferably a flexographic printing press, with at least one impression cylinder and with at least one pressure cylinder mounted on one end in the frame and at least one single-ended in the frame Ink application or anilox roller of an inking unit, the Bearings of the forme cylinder and anilox roller relative to the printing cylinder are movable in guides.
  • a printing press of this type is known from DE-GM 92 08 023. Cylinders with one end overhung create vibrations tilting spring mass systems. For this reason it is over known from DE-GM 92 08 449, in printing presses of the type specified Type the vibrations of the single-ended cylinders to dampen that on the free end region of the printing cylinder a ring is placed, the diameter of the diameter corresponds to the envelope cylinder described by the clichés. Through this ring placed on the end of the pressure cylinder it is guaranteed that this is on the impression cylinder and the anilox roller supports, or runs between the two, so that the pressure cylinder as it were at its free end between the printing cylinder and the anilox roller is clamped. Although this known arrangement already leads to considerable damping and suppression of the vibrations of the overhung Leads is the quality of the through the end area of the cylinder Printing cylinder executed pressure not optimal in all cases.
  • the object of the invention is therefore a printing machine of the beginning to create the specified type, including that of the end area of the overhung pressure cylinder is flawless.
  • this object is achieved in a printing press initially specified type solved in that on the frame Carrier or plate is articulated with bearings for receiving from shaft ends of the free ends of the printing or anilox rollers or with mounts for bearings placed on the shaft journals are provided and that the plate between a folded Position in which the overhung rollers are freely accessible are, and a pivoted position is pivotable, in which the journal of the free ends of the rollers on the plate are stored.
  • additional bearings are provided on the pivoting plate, which the Intercept the free ends of the overhung rollers and thereby unwanted vibrations of the free ends of the overhung Catch rollers and deflections that affect print quality could affect.
  • Printing cylinder jackets can be conventional cliché cylinders and format or form cylinders.
  • the cylinder's main bearing provided its on-the-fly storage cause.
  • the invention on the pivotable plate the intended bearings are essentially only auxiliary bearings, the interception of the ends of the overhung rollers to serve.
  • the main bearings of the flying bearings of the pressure roller and the Anilox rollers are movable to attach the impression roller to the impression cylinder and to be able to place the anilox roller on the printing roller and each for itself and possibly both together to be able to move relative to the impression cylinder.
  • the printing roller can fly on one end in one frame-fixed guide slidably guided first carriage and the anilox roller flying on one end in a slide guide of the first carriage slidably guided second Sledge be stored.
  • a flying storage of is, for example, rollers that can be moved relative to the impression cylinder known from DE-43 08 711 A1.
  • Each of the stops can be moved in a guide Be attached to the linkage, provided with a fine adjustment is.
  • the fine adjustment serves to set the free Roller ends if required for quality printing should be.
  • the fine adjustment can consist of a spindle drive.
  • the Gear part of the spindle drive on the plate in the longitudinal direction the spindle is adjustable and fixable on the plate.
  • This Design allows the free ends of the rollers intercepting postures to adjust quickly in the same way like the main bearings, for example when moving the platen should be in the down position.
  • the plate can be parallel to the spindle or the rod be provided with an elongated hole, that one carrying the gear part Bolt penetrates, the bolt with a Toggle screw for fixing the gear part to the slot is provided.
  • the gear part can be released by loosening the toggle screw according to the main bearings of the rollers quickly move. Is the gear part of the spindle through to the elongated hole the toggle screw clamped, the fine adjustment of the Make the spindle.
  • the fine adjustments can be made via the spindle drives can be done via the spindle drive for the linkage of the stop for the pressure roller both this Adjust the stop as well as the stop for the anilox roller, with a fine adjustment of the stop for the Anilox roller through the spindle drive of the stop of the anilox roller supporting linkage can be made.
  • a coupling bracket with two clamping jaws can be used for coupling be provided, the toggle screw bracing the clamping jaws the slot penetrated freely.
  • the abutments can be guided in and through the plate Drives can be moved.
  • the drives consist of pneumatic cylinders.
  • brackets arranged for the releasable counter bearing be.
  • the swiveled-in and swung-out position of the plate is expediently limited by stops.
  • the plate can be door-like through two hinge joints with the frame be connected.
  • the hinge joints have an eccentric characteristic have, such that the pivoting movement one Stop translational movement lifting off the shaft journal is superimposed. This configuration ensures that the stops are not against the end pins of the rollers or hit the bearings placed on them and damage them can.
  • the thicker side frame 4 are the Printing roller 2 and the anilox roller 3 overlying bearing blocks 6, 7 movably mounted on slide assemblies, the bearing block 6 arranged for the printing roller 2 on a carriage is, which is movable on guides of the side frame 4, and the bearing block 7 of the anilox roller 3 on guides of the bearing block 6 carrying carriages.
  • the roller bearing 10 of the pressure roller 2 is in the operating position pivoted door-shaped plate holding the auxiliary bearings 12 clamped between a stop 13 and an abutment 14.
  • the roller bearing 11 of the anilox roller 3 is in the operating position clamped between the stop 15 and the abutment 16.
  • the stop 13 is an end piece on a linkage 17 attached, which is longitudinally displaceable in a guide 18 is rotatably guided.
  • the stop 15 is attached at the end to a linkage 19, that is longitudinally displaceable in the same way in a guide 20 but is non-rotatably guided.
  • the guides 18, 20 are shown in FIG Way on the parallel longitudinal spars 21, 22nd a rectangular frame attached by cross members 22, 23 are connected.
  • In the illustrated embodiment are, as can be seen from Fig. 1, on the door pivotable plate 12 in eight holes 26 through Bolt 27 four frames 21 to 24 attached.
  • the illustrated An exemplary embodiment thus shows an eight-color rotary printing press.
  • the linkage 17 is through a spindle drive in the longitudinal direction the guide 18 adjustable.
  • the spindle drive consists of a Gear part 30, not shown, which is a spindle nut and contains a spindle rotatable by the operating button 31, so that by rotating the knob 31, the linkage 17 relative can be adjusted to the transmission part 30.
