Definitions

  • the invention relates to a printing press, preferably a flexographic printing press at least one impression cylinder, with at least one pressure roller and with at least one inking or anilox roller of an inking unit that is flying at one end are stored in the frame, the bearings of the printing roller and the anilox roller Movable relative to the impression cylinder in guides and quickly detachable bearings for catching the shaft journals of the free ends of the printing and anilox rollers are provided.
  • the Frame hinged to a plate with bearings for receiving the shaft journals free ends of the printing and anilox rollers or with receptacles for on the shaft journal attached bearings are provided.
  • the plate is folded down between one Position in which the overhung rollers are freely accessible and a swiveled in Pivotal position in which the shaft journal of the free ends of the Rollers are stored on the plate.
  • additional bearings are provided, which the free ends of the flying intercept stored rollers and thereby undesirable vibrations of the prevent free ends of the overhung rollers and deflections that may affect print quality.
  • the plate with the bearings can be proportionate remove quickly and easily so that the overhung rollers are accessible from the outside and the printing cylinder sleeves are easy and can be replaced quickly.
  • the printing cylinders with the interchangeable clichés carrying printing sleeves can be customary plate cylinders and format act or forme cylinder.
  • the object of the invention is therefore a printing press of the type specified Type to create, in which the free ends of the overhung pressure and It is easier to have anilox rollers caught in additional bearings.
  • this object is achieved in a printing press of the type specified at the outset Art solved in that in the frame transverse to the printing and anilox rollers at least one bearing block can be moved in guides, in which in the retracted Condition the shaft journals of the free ends of the printing and anilox rollers are stored are.
  • the free ends of the flying stored printing and anilox rollers easier in additional bearings of the pedestals store them in their guides in a precisely defined way their free positions storing and releasing positions movable and the Bearings or bearing brackets in a form that is easy to observe on the shaft journals or bearings are attachable.
  • a common one can be used to support the shaft journals of each pair of printing and anilox rollers Bearing block are provided. However, it is easier and clearer for storing the shaft journals of each pair of printing and anilox rollers in opposite directions provide movable pillow blocks.
  • window-like openings allow on the one hand an easy change of Printing cylinder sleeves and on the other hand, the guides for the or the bearing blocks be attached to one side of each window-like opening.
  • the pillow blocks are particularly stable when they are on both sides the window-like openings are made.
  • the pedestals can be moved by threaded spindles.
  • Bearings which are held in the bearing blocks, can be placed on the shaft journals are.
  • the holding heads can already be designed as bearings that support the shaft journals his. If the bearings consist of roller bearings, only the inner rings are on the Slotted shaft journal.
  • the holding heads with devices for lateral adjustment are expedient of the camp.
  • the holding heads are expediently in the axial direction of the printing and anilox rollers can be moved by pressure-piston-cylinder units. Let it this way the brackets or the bearings in the axial direction on the Slide on the shaft journal.
  • a printing press frame 1 In a printing press frame 1 are in the usual and therefore not described in detail Way, an impression cylinder 2, which is shown in Fig. 1 only by a part of it Circumferential line is shown, and to this adjustable pressure cylinder 3 and this associated anilox rollers 4 stored.
  • the impression cylinder 1 are above it Scope distributed several, for example six, assigned printing units, each on movable carriages on the fly mounted pressure rollers 3 and associated Have anilox rollers 4 with inking units.
  • the side frame 8 attached a guide rail 9, on the sled-like bearing blocks 10, 11 are slidably guided parallel to themselves.
  • the bearing blocks 10, 11 are displaceable on the common guide 9 by spindle drives.
  • the shift takes place through a freely rotatable but in Axial direction immovable in one on the front of the side frame 8th attached console 12 mounted threaded spindle 13, the bearing block 11 in a Drilled through and screwed into a nut 14 fastened in this hole is.
  • the threaded spindle is via a belt drive 15 from one to the other Side frame 8 fixed gear motor 16 driven.
  • the bearing blocks can also, as is the case with the left bearing block 10 in FIG the pressure cylinder 3 is shown by a non-rotatable and axially immovable the bearing block connected threaded spindle 17 take place.
  • the threaded spindle 17 is screwed into an internally threaded tube, which is on its outer End is provided with a toothed belt pulley 18. That is the internal thread supporting tube 19 is freely rotatable but axially immovable in one with the side part 8 connected console 20 stored.
  • the toothed belt pulley 18 is driven again by means of a toothed belt 21 connected to the side frame 8 Gear motor 22.
  • the bearing blocks 10, 11 are on their mutually facing inner sides with the Guide 9 provided parallel recesses 24, 25. Wear these recesses at their inner ends to the shaft journals 5, 6 parallel guides 26, in which Recording heads 27 are slidably guided in the axial direction. These recording heads are provided with blind holes in which roller bearings 28 are held, whose inner rings can be pushed onto the shaft journals 5, 6. To postpone the Recording heads 27 with the bearings 28 on the shaft journals 5, 6 and for pulling off pressure-piston-cylinder units 30 are provided, the piston rods of which the recording heads 27 are connected.
  • the pairs of printing and anilox rollers distributed over the circumference of the impression cylinder 2 are provided in the usual way with drives that over the opposite Shaft journal 32 take place.
  • the guides 9 advantageously run parallel to the pressure and Anilox rollers bearing carriage, so that the bearing blocks 10, 11 by appropriate Control of the spindles moving by the same amount as each which can be used to move these sleds.
