Definitions

  • the invention relates to a bearing for printing unit cylinders or the like with adjustable side register, in which the cylinder provided with inner cones is clamped between corresponding complementary outer cones of a shaft mounted in the machine frame, which is axially immovably mounted in a sleeve which is provided with a thread and by a Screw connection is displaceable in the axial direction with a sleeve which is immovable relative to the frame in the axial direction.
  • the cylinder is mounted on a continuous shaft, with which an outer cone is firmly connected, while the other outer cone is arranged on a sleeve which can be pushed onto the shaft and which can be tensioned by a screw connection for tightening the cylinder in the direction of the other outer cone.
  • the shaft can be rotated on one side, but is axially immovable in a sleeve provided with a handwheel, which is screwed into a sleeve that is axially immovable in the frame. Since the shaft is axially displaceable on the opposite side, the side register can be adjusted by turning the sleeve using the handwheel.
  • the object of the invention is to provide a mounting of the type specified at the outset, which allows the cylinders to be changed quickly and easily and which, in particular after a cylinder change, enables the side register to be set in a simple manner with a high clamping force of the cylinder.
  • this object is achieved in that the outer cones are arranged at the mutually facing ends of shaft journals mounted in the frame, one of which is axially non-displaceably, mounted in the sleeve, which is displaceable relative to the machine frame in the axial direction, but guided non-rotatably, in that the sleeve but axially non-displaceably mounted sleeve is screwed with a aschi- in M nengestell rotatable, that of a rotary drive for axial Cylinder is provided, and that the shaft journals can be clamped against each other by the piston rods of hydraulic piston-cylinder units, the cylinder sides of which change in volume when the side register is set in opposite directions.
  • the storage according to the invention allows a quick and easy change of the cylinder simply by pulling a shaft journal out of the inner cone immediately after or when the piston rod loading it back and the other shaft journal by actuating the rotary drive by the spindle drive created by the screwed sleeves Retracting the corresponding piston rod is retracted.
  • the cylinder released in this way can be exchanged for another, in the inner cones of which the outer cones of the shaft journals are retracted in a correspondingly reverse manner.
  • the shaft journal located in the sleeve opposite the shaft is rotatably connected to the axially aligned piston rod so that this shaft journal can be retracted at the same time as the piston rod is retracted.
  • the sleeve supporting the shaft journal can be provided with a radial lever, the end of which is guided in an axially extending guide groove fixed to the frame.
  • the sleeve screwed to the sleeve supporting the shaft journal can be rotated via a geared motor.
  • the side register can then be adjusted in a simple manner only by actuating the geared motor, for example by pressing a button, the corresponding cylinder sides of the piston-cylinder units then being connected to one another in a manner which enables axial displacement by means of a control valve.
  • the shaft journal mounted in the sleeve is expediently provided with markings which indicate the side register at an axial distance and can be scanned by sensors.
  • the sleeve bearing the shaft journal is screwed directly or via a peg-shaped extension into the bottom of the sleeve mounted in the frame and that the piston rod of the piston-cylinder unit on the sleeve or the extension connected thereto supports.
  • a cylinder 1 for example a printing unit cylinder, has on both sides concentric to its central axis inner cones 2, 3, in which the outer cones 4, 5 of centering and rotatably mounted shaft journals (quills) 6, 7 engage, which hold the cylinder 1 in the working position.
  • the outer cone 4 is positively connected to the cylinder 1 with a spring 8 which engages in a groove milled into the inner cone 2.
  • the shaft journals 6, 7 are rotatably mounted in bearing bushes 10, 11 which are firmly connected to the frame 12.
  • the bearing bushes 10, 11 are designed such that the Shaft journals 6, 7 via which these roller bearings are displaceable in the axial direction.
  • the shaft journal 7 is rotatable with the piston rod of a hydraulic cylinder 13 which is fixed to the frame, but is axially immovably connected.
  • the shaft journal 6 is rotatable in a bearing bush 14 fixed to the frame and is also axially immovable.
  • a gearwheel 16 which meshes with a gearwheel 17, is wedged on the shaft journal 6.
  • the gear 17 sits on a shaft, not shown, which is in drive connection with the main drive.
  • the shaft journal 6 is rotatable in the sleeve 18, but is axially immovable.
  • the sleeve 18 is axially displaceable • in the sleeve 19 which surrounds it.
  • the radial lever 20 With the sleeve 18, the radial lever 20 is connected, the end of which is guided in the groove of a guide track 21 fixed to the frame, so that the sleeve 18 cannot carry out any rotation, but rather only a movement in the axial direction.
  • the length 22 of the guideway 21 is dimensioned such that the lever 20 remains in engagement with the guideway 21 during its entire axial displacement.
  • the gear 17 is so wide that it always remains in engagement with the gear 16.
  • a ring gear 23 is firmly connected, which meshes with a bevel gear 24, the shaft of which is fixed to the frame and is connected to a geared motor (not shown).
  • the sleeve 18 is connected at the end to a pin 18.1, the outer surface of which is provided with a thread which is screwed into a threaded bore in the bottom of the guide sleeve 19.
  • the shaft journal 6 can be withdrawn entirely from the cylinder 1 or tensioned against the latter by the geared motor.
  • the cylinder 1 is tensioned from the right via the shaft journal 7 by the hydraulic cylinder 13.
  • a further hydraulic cylinder 26 is provided, the piston rod of which is supported on the end face of the pin 18.1.
  • Fig. 4 the hydraulic circuit diagram for the two hydraulic cylinders 13, 26 is shown schematically, which can be controlled by a four-way valve 27 together towards and away from each other and separated from the pressure medium source.
  • a sleeve 28 is fastened with three protruding switching rings 29, 30, 31, which can be scanned by sensors (initiators) 32, 33. These serve to ensure that the correct side register position of the cylinder is achieved.
  • the middle position is reported by the initiator 32 when the shaft journal 6 is shifted to the right.
  • the maximum permissible displacements to the right and left are reported by the initiator 33 when the switching rings 30 and 31 come into their effective range.
