Definitions

  • the invention relates to a cylinder of a rotary printing press consisting of a cylinder barrel with a detachably connected bearing journal according to the preamble of claim 1.
  • DE-PS 8 00 932 describes a calender with removable rollers.
  • the rollers are provided with removable pins, the pins having a conical recess and a ball of conical shaft ends.
  • the disadvantage here is that at least one pin is arranged axially displaceable in the frame.
  • the invention has for its object to provide a cylinder consisting of a cylinder ball and flanged bearing journal of a rotary printing press, in which the cylinder ball can be separated from the journal and a journal is axially moved only minimally.
  • sleeves can be installed in a simple manner in spite of these bearer rings in the cylinder according to the invention.
  • the simultaneous use of sleeves and bearer rings ensures that the rotary printing press runs extremely smoothly, thereby achieving the highest print quality.
  • a highly precise centering of the bearing journal and cylinder barrel is made possible by interacting cones.
  • a cylinder 1 of a rotary printing press essentially consists of a cylinder barrel 2, on the end faces 3, 4 of which a removable bearing journal 6, 7 is fastened.
  • the cylinder 1 is mounted in frames 9, 11 so as to be rotatable about an axis of rotation 8.
  • On these journals 6, 7 is a z. B. formed as a bearer ring 12 flange and provided on a cylinder ball 2 facing end face 13 with a conical recess 14.
  • This conical recess 14 is concentric with the axis of rotation 8 of the cylinder 1.
  • the cylinder barrel 2 can be designed, for example, as a rubber cylinder.
  • an outer surface 16 of the cylinder barrel 2 can be provided with an endless rubber coating 17.
  • This rubber coating 17 can be vulcanized onto the outer surface 16, glued or applied, for example, as a sleeve-shaped tube, a so-called sleeve be.
  • the bearer ring 12 is provided with a plurality of holes 18 distributed around the circumference, through which screws 19 extend, which interact with threaded holes 21 of the cylinder barrel 2. As a result, the respective bearing journal 6, 7 is screwed to the cylinder barrel 2.
  • At least one centering and releasing device 22 is arranged in the cylinder barrel 2.
  • This centering and releasing device 22 essentially consists of two pins 23, a compression spring 24 and at least one adjusting means 26.
  • the pins 23 are mounted concentrically and axially displaceably with respect to the axis of rotation 8 of the cylinder 1 in an axially extending bore 27 of the cylinder barrel 2.
  • the otherwise cylindrical pins 23 are provided with a conical end 28 at one end facing the bearing pins 6, 7. This conical end 28 and the conical recess 14 are adapted to one another.
  • a threaded bore 32 is made in this second end 29 of the pin 23, into which a tension screw 34 provided with a collar 33 engages, the collar 33 also being supported on the stop disk 31.
  • This lag screw 34 can by means of a drive, for. B. pneumatic motor operated, or as in the present, first embodiment with a Hexagon socket 36 may be provided.
  • actuate the tension screw 34 is the non-rotating pin 23 and the bearing pins 6, 7 are provided with a continuous bore 37.
  • the pin 23 is designed as a piston which can be acted upon by a pressure medium.
  • the conical end 28 of the pin 23 is offset with a smaller diameter than the bore 27 of the cylinder barrel 2.
  • the cylinder barrel 2 is closed at the end with a cover plate 39 which is adapted to the offset end 28 of the centering bolt 23 and is provided with a seal 38.
  • a pressure chamber 41 is thus formed between the stepped end 28 of the pin 23 and the cover plate 39. This pressure chamber 41 is connected by means of a channel 42 to a connection opening 43 located in the cylinder barrel 2.
  • the screws 19 connecting the bearer rings 12 and the cylinder barrel 2 are loosened.
  • openings can be provided in the frames 9, 11, for example.
  • the bearer rings 12 or a bearer ring 12 and the cylinder barrel 2 are axially displaced a small distance by the compression spring 24. The size of this path results from an axial play of the bearings of the journals 6, 7 in the frame 9, 11.
  • the respective tension screw 34 is actuated by means of a tool reaching through the respective bore 37 of journals 6, 7 and journals 23 and the Pin 23 is pulled axially away from the bearer rings 12 into an interior of the cylinder barrel 2 until the conical ends 28 are at least congruent with the end faces 3, 4 of the cylinder barrel 2.
  • the cylinder barrel 2 can now be removed from between the journals 6, 7 remaining in the frames 9, 11.
  • connection openings 43 are connected to a pressure medium source for moving the pins 23 into the interior of the cylinder barrel 2.
  • the respective pressure chamber 41 is pressurized and the required axial movement of the pins 23 is generated.
