Definitions

  • the invention relates to a bearing for format cylinders of a printing press, preferably a flexographic printing press, with exchangeable sleeve-shaped format cylinder jackets according to the preamble of patent claim 1.
  • the bearing block In a bearing of the type specified in DE-C-891 396, the bearing block is designed as a conical disk and is held in a complementary conical opening of the machine frame wall by clamping elements. The loosening and fixing of the bearing block is therefore relatively expensive in the known storage.
  • a bearing for a format cylinder known from FR-A-2 353 395
  • a bearing is completely withdrawn from a bearing journal of the format cylinder in the axial direction by means of a special pull-off device, while on the journal which projects outward from the undissolved bearing, the format cylinder in its horizontal position-holding abutment or a hydraulically operated pulling device attacks, so that the format cylinder jacket can be removed from the format cylinder core which is freely cantilevered on an axle journal and can be replaced by another jacket.
  • this known device not only is the complete removal of a bearing complex, but the undissolved bearing is also undesirably stressed when changing the format cylinder jacket, since this has to absorb the full reaction forces. which result from the support of the free end of the bearing journal on an abutment or on the hydraulic pulling device.
  • the object of the invention is to provide a bearing according to the preamble of claim 1, which allows easier and faster replacement of the sleeve-shaped format cylinder jacket.
  • the format cylinder is first supported in the area of its non-detachable bearing in such a way that it is held in a cantilevered position in a cantilevered manner even without the bearing to be detached. Subsequently, the detachable bearing is pushed on its slide-shaped movable support part so far in the axial direction that it is released from the shaft journal of the format cylinder and the format cylinder in the area of the undissolved bearing is only held by the support device. The inner ends of the guides of the bearing support part are then released from the machine frame or the format cylinder slide, so that the bracket with the guides can be pivoted out and the bearing comes completely out of the area of the format cylinder. The sleeve-shaped format cylinder jacket can then be pulled off the format cylinder core in the axial direction with the usual aids, without bearing or support parts being in the way.
  • the fixation can consist, for example, of a T-shaped head which can be inserted into a corresponding recess in the supporting part and which can be clamped to the machine frame and the format cylinder slide by an eccentric.
  • the support device for the format cylinder consists of hydraulic piston cylinder units arranged in the machine frame or on the format cylinder slide on both sides of the undissolved bearing, of which the piston rod of the inner cylinder with a support shell which can be extended against an inner part of the shaft journal of the format cylinder core and the piston rod of the outer cylinder with an outer part the retractable support yoke, which forms the upper boundary of a window-like section of a pulling part, is provided for the shaft journal of the format cylinder.
  • the window-like The cut-out must have such a high height that the format cylinder can be lifted into its "print-off" position without hindrance during the printing operation when the pulling part is raised.
  • Format cylinders in particular from flexographic printing presses, are usually mounted on format cylinder slides, so that the bracket with the guides for the supporting part of the detachable bearing forms the front end piece of the format cylinder slide.
  • the supporting part can be guided over ball bushings on two guide rods made of round steel.
  • the guide rods are expediently provided with axial bores in which screw bolts are arranged for their locking, which are provided with heads supported on the outside of the bracket and provided with handles and at their front ends with threaded parts which can be screwed into the format cylinder slide.
  • the printing cylinder 2 which is provided with a drive (not shown), is mounted in the machine frame 1 of the flexographic printing press.
  • the machine frame 1 is provided with approximately radial support arms or brackets 3, on which format cylinder slides 4 are guided in a longitudinally displaceable manner and which are provided on both sides with bearing blocks 5 for the format cylinders 6.
  • the format cylinder slides 4 are provided with spindles for moving the format cylinders 6 to the impression cylinder 2.
  • the bearing blocks 5 for the format cylinders are provided with incorporated cylinders and with pistons provided with lip seals, as are described, for example, in DE-C-29 41 521.
  • the format cylinder 6 is provided with shaft journals 20, 21 which are mounted in slide bearing bushes 22, 23 which are provided with spherical outer sides which are held in corresponding spherical shells of the bearing blocks.
  • the leg 11 of the bracket 3 is provided on both sides with support pieces 24, 25 to which hydraulic piston cylinder units 26, 27 are attached.
  • the support pieces 24, 25 can also be attached to the format cylinder slide 4.
  • the piston rod 28 of the piston-cylinder unit 26 carries at its upper end a support shell 29 which can be moved from below to support the format cylinder 6 against a section 30 of the shaft journal of the format cylinder 6 that compresses via a shoulder.
  • the outer section 31 of the shaft journal of the format cylinder 6 is tapered over a shoulder in relation to the section 20 serving for storage and extends through an elongated window 32
  • Traction part 33 which is connected to the piston rod 34 of the piston-cylinder unit 27.
  • the pulling part 32 engages with a screwed-on yoke 35 on the outer section 31 of the shaft journal, whereby the yoke 35 can be lowered by retracting the piston rod 34 to such an extent that it rests on the upper side of the section 31 of the shaft journal.
  • the lever 36 connected to the piston rod 34 actuates the microswitch 37. This ensures that the "print-down" position and the disengaged drive are locked to the format cylinder 6.
  • the swivel bracket 41 which consists of an angled lever, is pivotably connected to the web 12 of the format cylinder slide 4 about the vertical hinge pin 40.
  • the guides consisting of the rods 43, 44 are fastened parallel to one another.
  • the opposite ends of the guide rods 43, 44 are connected to one another by the web 45.
  • the bearing block 14 for the bearing 16 is guided in a longitudinally displaceable manner.
  • the bearing block 14 is provided with two bores 46, in which ball bushings are held by clamping rings which run on the guide rods 43, 44.
  • the guide rods 43, 44 are provided with axial bores which pass through the bolts 48.
  • the outer ends of the bolts 48 are connected to head pieces 49, which are supported on the outer sides of the leg 42 of the swivel bracket 41 and are provided with handles 50.
  • the inner ends of the bolts 48 are provided with threads 51 which in Corresponding threaded bores of a wall part 52 of the web part 12 of the format cylinder slide 4 can be screwed in.
  • the swivel bracket 41 has two forked bearing legs 54, 55, which enclose a web-shaped bearing part 56 of the format cylinder slide 4.
  • the support shell 29 and the yoke 35 of the tension member 33 are first moved into their support positions shown in FIG. 2.
  • the format cylinder 6 is held on its left shaft journal at its sections 30, 31, so that after the bearing 16 has been removed, the format cylinder 6 remains in its position.
  • the not shown locking or locking of the bearing block 14 with the web 12 of the format cylinder slide 4 is first released. After this loosening and after a possible loosening of the bearing shells of the bearing 16, the bearing 16 can be pulled off the shaft journal 21 by axially moving the bearing block 14. The bearing block 14 is pulled out so far that it is in the vicinity of the leg 42 of the swivel bracket 41. The screw bolts 48 are then rotated via the handles 50 until they are screwed out of the web part 52 of the format cylinder slide 4. In this position, the swivel bracket 41 with the bearing block 14, the piston-cylinder unit 18 and the bearing 16 can be pivoted into the dash-dotted position shown in FIG. 3. In this, the sleeve-shaped format cylinder jacket can now be removed from the format cylinder 6 for exchange with another in the usual way.
