Definitions

  • the invention relates to a cylinder Rotary printing machine consisting of one Cylinder balls with detachably connected bearing pins according to the preamble of claim 1.
  • DE-PS 8 00 932 describes a calender with removable rollers.
  • the rollers are removable Provided cones, the cones a conical Deepening and a bale of tapered stumps exhibit.
  • the disadvantage here is that at least one spigot is wide is axially displaceable in the frame.
  • the invention has for its object one Cylinder balls and flanged bearing journals existing cylinders of a rotary printing press create where the cylinder bale from the trunnion can be separated and a journal axially only is moved 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.
  • 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.
  • This centering and Release device 22 consists essentially of two Pin 23, a compression spring 24 and at least one Adjustment means 26.
  • the pins 23 are axially aligned extending bore 27 of the cylinder barrel 2 concentrically and axially displaceable with respect to the Axis of rotation 8 of the cylinder 1 is mounted.
  • On one Bearings 6, 7 facing ends are otherwise cylindrical pin 23 with a conical end 28 Mistake. This conical end 28 and the conical Well 14 are adapted to each other.
  • second end 29 of the pin 23 attacks the compression spring 24, which is against one in the Bore 27 of the cylinder barrel 2 located Support stop disc 31.
  • this is second end 29 of the pin 23 has a threaded bore 32 introduced into the one provided with a collar 33
  • Tension screw 34 engages, the collar 33 also supported on the stop disc 31.
  • This Tension screw 34 can by means of a drive, for. B. Pneumatic motor operated, or as in present, first embodiment with a Hexagon socket 36 may be provided.
  • To operate the Tension screw 34 is the anti-rotation pin 23 and are the journals 6, 7 with a continuous Provide hole 37.
  • stop disk 31 it is also possible for the stop disk 31 to be dropped and the two opposite Pin 23 by means of a common compression spring 24 and a common threaded spindle, which is then a right and has a left-hand thread to connect.
  • 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.
  • both pins 23 by means of one Common working cylinder that can be pressurized to couple and thus to those in the cylinder bale 2 to dispense with incorporated pressure chambers 41.
  • the rotary bearer will be the bearer rings 12 and screws 19 connecting the cylinder barrel 2 solved.
  • the frames 9, 11 openings may be provided.
  • the compression spring 24 By the compression spring 24, the bearer rings 12 and a respectively Bearer ring 12 and the cylinder barrel 2 around a small one Axially displaced. The size of this path results from an axial play of the bearings of the journals 6, 7 in frame 9, 11.
  • the movement of the Pin 23 in the interior of the cylinder barrel 2 die Port openings 43 with a pressure medium source connected.
  • the respective pressure chamber 41 is thus also Pressurized medium and the required axial movement the pin 23 produces.
