Definitions

  • the invention relates to a bearing for a pressure cylinder equipped with a slide-on sleeve.
  • a bearing for a printing cylinder (DE-PS 37 15 536) is known, in which a jaw chuck is arranged displaceably on the printing unit side wall, in which a bearing seated on the journal of the printing cylinder is held in the operating state and can be moved apart and through via the diameter of the sleeve adjustable stops in the holding position for the printing cylinder is adjustable.
  • the expandable jaw chuck including the necessary drive mechanism, requires a relatively large amount of space in the radial direction of the printing cylinder, which is however only available to a very limited extent in a multi-cylinder arrangement in a printing unit.
  • the straight guides for the jaws require a relatively high manufacturing effort.
  • the invention has for its object to provide a bearing for a pressure cylinder equipped with a push-on sleeve according to the preamble of claim 1, which allows a sleeve change in the rotary printing press with easy-to-manufacture, space-saving means and a reliable, adjustable support of the printing cylinder in the Operating condition guaranteed.
  • rollers which serve both to support and to support the printing cylinder, permit simple journalless mounting of the printing cylinder.
  • rollers By executing one of the side walls of the recesses as an insertable cover segment according to claim 3, the rollers can be easily installed.
  • rollers allow the rollers to be arranged on the side of the frame if the cutouts cannot be arranged in the latter for design and production reasons or if a rotary printing machine with sleeve-equipped printing cylinders is subsequently retrofitted.
  • the continuous ring groove according to claim 6 is particularly easy to manufacture.
  • the embodiment mentioned in claim 9 allows an effective adjustment of the eccentric bolts with few transmission elements in a narrow space and can therefore be used advantageously in a multi-cylinder arrangement in a printing unit.
  • the adjustable stop according to claim 10 and in a special embodiment according to claim 11 allows an easy adjustment of the rollers in the operating state depending on the pressure cylinder position.
  • Claims 12 and 13 favor centering of the sleeve when pushed onto the pressure cylinder.
  • race ring allows it to be optimized independently of the rest of the cylinder body of the impression cylinder with regard to its use as a running surface for the rollers.
  • Claim 20 allows a particularly rational design of the rollers as roller bearings.
  • the individual adjustability of the eccentric bolt causing a pivoting of the rollers allows u. a. an optimal setting for the respective load condition of the printing cylinder.
  • the two most stressed roles should be switched on and off at the same time and in opposite directions.
  • the solution according to claim 22 enables different positions of the printing cylinder to be realized via a corresponding radial adjustment of the rollers supporting it.
  • Claim 24 contains a cheap drive variant for adjusting the eccentric bolt.
  • Claims 25 to 27 contain optimized embodiments for adjusting the eccentric bolts with regard to the maximum load on the rollers.
  • Fig. 1 shows the side view of from in a frame wall 1 eccentric bolt mounted on a rotary printing press 2 rotatably arranged rollers 3 circumferentially supported printing cylinder 4.
  • the rollers 3 are each arranged in a pocket-shaped recess 5 of the frame wall 1, and the eccentric bolts 2 are mounted on the one hand in a wall 6 of the frame wall 1 delimiting the recess 5 and on the other hand in a cover segment 7 firmly inserted in the latter (FIG. 3) and with an axle 8 outside the frame wall 1 connected to a lever 9, on which a pressure medium-operated, working cylinder 10 is pivotally mounted in the frame wall 1 (Fig. 1).
  • the pivoting movement of the lever 9 is limited in the direction causing the rollers 3 to press against the pressure cylinder 4 by a stop 13 consisting of a body 12 fastened to the frame wall 1 and penetrated by a set screw 11 serving as a system in a threaded bore (FIG. 1).
  • Fig. 2 shows a pressure cylinder 4 with a slide-on sleeve 14.
  • the rollers 3 are pivoted by rotating the eccentric bolts 2 from the pressure cylinder 4 additionally supported on the opposite side, not shown, so that the opening in the frame wall 1 in the form of a compared to the outer diameter of the sleeve 14 enlarged wall bore 15 is exposed.
  • the pressure cylinder 4 is equipped with a run-up bevel 16 on the end for circumferential pushing on of the sleeve 14 and on this side with a running surface 17 for the rollers 3 which is set back relative to the inner diameter of the sleeve 14.
  • FIGS. 4 and 5 show a ring 18, which is equipped with pocket-shaped recesses 5 I for the rollers 3 I and is laterally attached to the frame wall 1 I while leaving its opening open.
  • 6 and 7 show a segment 19, which is separately attached laterally to the frame wall 1 II while leaving its opening, each with a pocket-shaped recess 5 II for a roller 3 II .
  • the pocket-shaped recesses 5; 5 I ; 1 to 4 can also each by an easy to manufacture, all roles 3; 3 I ; detecting, to the wall hole 15 open, continuous ring groove are replaced.
  • the tread 17; 17 I ; 17 II for roles 3; 3 I ; 3 II can either be hardened using a suitable material or coated with an additional wear layer made of metallic alloys or non-metallic hard materials, for example made of ceramic. Possibly. this wear layer can also be sealed with organic materials based on epoxy resin.
  • rollers 3 III With regard to a completely mountable assembly, it is favorable to store the rollers 3 III with the eccentric bolts 2 I in a wall socket 24 which is inserted coaxially to the pressure cylinder into the frame wall 1 III and which has a smallest inside diameter which enables the sleeve change and is screwed to the frame wall 1 III .
  • the rollers 27; 28 arranged in the area of the maximum load at a closer distance and synchronously adjustably connected to one another by a coupling gear 29, so that only one eccentric bolt 30 has to be equipped with a drive consisting of worm drives 31 and a servomotor.
  • the third roller 32 which is not heavily loaded, but is essential for an exact guidance of the printing cylinder 4 II , is compared with the other two rollers 27; 28 first off and last employed.
  • the pressure medium for the working cylinder 33 is advantageously adjustable and the adjustment path for the eccentric bolt 34 is not limited by stops.
  • FIG. 12 shows a variant of FIG. 10, in which the servomotors 26 I for the individual eccentric bolts 2 III each use sensors 35 that fix the position for pressure on and off and the change of the sleeve of the pressure cylinder; 36; 37 can be controlled.
  • the servomotors can also be movable against stops that fix the position for printing on and off and the change of the sleeve of the printing cylinder, but the middle stop for the pressure shutdown must be pivotable away.
