Definitions

  • the invention relates to a bearing for a cylinder in a printing press, like plate and rubber cylinders that can be adjusted there that it moves in the direction of a radial component.
  • the invention has for its object an arrangement for an adjustable To create cylinders in a printing press which enables to completely dispense with hydraulic or pneumatic working cylinders.
  • this object is achieved by a cylinder attached to the cylinder and released radially from this lever, over which the cylinder is driven by a stationary servomotor in Circumferential direction is adjustable.
  • the pressure setting of the Cylinder-serving movement of the lever from a pure linear movement caused.
  • a fixed arrangement of the Servo motor allows, for example, as an electric servomotor can be. The then pure linear stroke movements can be done with machine components with roller bearings without play.
  • the lever can be screwed to the cylinder which it is to adjust and the servo motor can be on a housing wall of a machine frame attached, for example also screwed.
  • the cylinder can be placed in the housing walls of the machine frame via eccentric bearings be rotatably supported, one eccentric bearing one in each associated housing wall held outer ring with concentric bore and an inner ring disposed therein and attached to the cylinder with an eccentric bore.
  • the output shaft of the servo motor can be used as a threaded spindle of a worm gear be executed, the mother of one on the lever of the cylinder acting in the circumferential direction of a carriage Linear guide is held.
  • the linear guide can be used as a roller guide with a guide rail, which is attached to one of the housing walls, and four to the carriage mounted, rollable along the guide rail rollers his.
  • the carriage can be parallel to the transverse direction of the guide rail at a distance two in a row on a common, of which Lever-held pegs can be arranged on supporting rollers that engage the carriage in its one direction of travel directly and in its support in another direction using an adjustable clamping piece.
  • a feed screw acting on the clamping piece in the carriage be arranged.
  • a cylinder 1 which acts as a pressure roller, for example, is in the housing walls a machine frame of a printing press via eccentric bearings rotatably mounted. 2 of which are an outer ring 2 with a concentric one Bore and an inner ring 3 with an eccentric bore can be seen.
  • This Eccentric bearing is located in the housing wall 4. It is a roller bearing executed and allows besides the pivoting of the cylinder 1 to an axis that runs parallel to its longitudinal axis 5, also its displacement in the axial direction.
  • a servo motor 6 is provided, which is designed as an electric servomotor and attached to a bracket 7 screwed to the housing wall 4 is.
  • the rotor shaft of the servo motor 6 is at the output end Threaded spindle 8 of a worm gear drive executed. It is from one Surround nut 9 of this hobbing drive, which on the carriage 10th a linear guide is attached. A guide rail 11 of the linear guide is also carried by the console 7. The carriage 10 is on it supported longitudinally.
  • a lever 13 is attached, the radial of protrudes from the cylinder and at its end facing away from the cylinder carries a pin 14 on which two support rollers 15 and 16 to both Sides of the lever 13 are rotatably mounted.
  • One of the two support rollers 15 is supported within a recess of the carriage 10 in a longitudinal direction the guide rail 11 directly on the carriage 10.
  • the other Support roller 16 is supported in the opposite longitudinal direction of the Guide rail 11 on a clamping piece 17, which within the Carriage is arranged axially displaceable and in its recess protrudes.
  • a feed screw is used to adjust the clamping piece 17 18, which is screwed into a threaded bore of the carriage 10, there is in front with the clamping piece 17 and with a screwed Mother 19 is countered on the carriage.
  • By twisting the Adjustment screw 18 can preload the two support rollers 15 and 16 without play become.
  • the linear rollers By moving the carriage 10 along the guide rail 11 of the The linear rollers are the support rollers 15 and 16 between two end positions the print job postponed.
  • the connection of the support rollers remains 15 and 16 on the carriage 10 without play, since the distance between the two clamping surfaces, the diameter of the support rollers 15 and 16 corresponds, remains constant. Because the support rollers are on a circular path move the center axis of the outer ring 2 of the associated eccentric bearing, the additional lifting movement of the support rollers 15 and 16 must be compensated become. This is done in that the support rollers on the clamping surfaces the carriage 10 and the clamping piece 17 upwards or downwards can roll down.
