Definitions

  • the invention relates to a method and a device for coupling a cylinder of a rotary printing press to a drive gear according to the preamble of claims 1 and 4.
  • DE-Gbm 1 858 031 shows a device for coupling a cylinder of a rotary printing press to a drive gear.
  • a cylinder barrel provided with a first clutch disc is pressed against a second, axially adjustable clutch disc by means of a working cylinder. This clutch disc is rigidly connected to the drive gear.
  • a disadvantage of this device is that it is not possible to decouple the drive wheel from the cylinder barrel without dismantling the cylinder barrel.
  • the invention has for its object to provide a method and an apparatus for coupling a cylinder of a rotary printing press.
  • the device according to the invention achieves a gentle, low-wear engagement during a controllable engagement process, since two rotating relative to each other Clutch discs are pressed against each other with reduced force compared to the engaged state.
  • the two pressures occurring in a working cylinder are measured by means of a pressure switch and used to display the clutch status.
  • This pressure switch can be arranged in the feed line of the working cylinder. This means that there are no problems due to oil mist, data transmission from rotating or axially displaceable parts.
  • a control valve used in the device for discharging a certain amount of pressure medium from the working cylinder is small and simple. It is operated directly by the interaction of the clutch discs. It is particularly advantageous that an annular gap formed by the control piston and pressure sleeve discharges a quantity of pressure medium into the open when the control valve is open and at the same time serves as a guide for the control piston.
  • the device according to the invention is shown in the drawing and is described in more detail below.
  • a cylinder of a rotary printing press can be connected to a drive gear 3 on a cylinder journal 1 by means of a switchable clutch 2.
  • This switchable clutch 2 consists of a first 6 and a second 4, each annular clutch disc, which are each provided on their opposite plane sides with end teeth 7, 8.
  • the spur gears 7, 8 are adapted to one another in such a way that the clutch 2 can only engage in a single position in which the two clutch plates 4, 6 are clearly in relation to one another, ie the clutch 2 is designed as a unique clutch.
  • the one clutch disk 4 can be provided with one or more teeth, for example wider teeth or teeth, which differ from the other teeth of the spur teeth 7, 8, and the other associated clutch disk 6 can be provided with tooth gaps adapted thereon.
  • One of the two clutch disks 4, 6 is rigidly connected to the cylinder journal 1.
  • the left clutch disc 4, which is closest to a cylinder barrel, and a gearwheel 9 for driving further cylinders (not shown) or an inking unit are fastened on the cylinder journal 1 by means of a feather key 11.
  • the cylinder is axially displaceable with the clutch disc 4 and the gear 9 for setting the side register.
  • the right clutch disc 6 is torsionally rigid, but axially displaceably connected to the drive gear 3.
  • the clutch disc 6 on its circumference an external toothing 12 with a width b12, z. B.
  • b12 18 mm, which in an introduced into the drive gear 3 internal teeth 13 with a width b13, z. B.
  • the drive gear 3 is attached to a hub 14.
  • This hub 14 has a bore 16 adapted to the cylinder pin 1, so that the hub 14 with the drive gear 3 is rotatably and axially displaceably mounted on the cylinder pin 1.
  • the axial shift which is used to set the circumferential register, takes place by means of an axially displaceable spindle 17, which is mounted in the cylinder journal 1 and is connected to a register setting device (not shown), which is rigidly connected to the drive gear 3 via a disk 18.
  • a working cylinder 19 is flanged to this hub 14 of the drive gear 3.
  • the working cylinder 19 has an annular, axially displaceable piston 21, which acts on cylindrical pressure pieces 22.
  • a plurality, e.g. B. 8 pieces, these pressure pieces 22 are evenly supported in the circumferential direction in bores 23 of the hub 14 and connected by means of screws 24 to the right clutch disc 6.
  • the pressure pieces 22 are provided with a collar 26 at their end cooperating with the piston 21. Between this collar 26 and the hub 14 22 compression springs 27 are arranged on the pressure pieces.
  • With the working cylinder 19 is a rotary entry 28 connected, which supplies a cylinder space 31 with pressure medium via a bore 29.
  • a feed line 32 to the rotary inlet 28 is a not shown, for. B.
  • the switching point is set to 5 bar, for example.
  • the cylinder space 31 is connected via a bore 33 made in the piston 21 to a line 34 which in turn connects to a control valve 36.
  • the control valve 36 is fixedly mounted in the right clutch disc 6 and interacts temporarily with the left clutch disc 4.
  • This control valve 36 consists essentially of a housing 37, a control piston 38, a compression spring 39 and a pressure sleeve 41 has provided.
  • a second, continuous bore 44 with an inner diameter d44, z. B. d44 6.5 mm.
  • the control piston 38 is arranged to be movable in the longitudinal direction.
  • This control piston 38 has at its first end a conical sealing head 46, this conical sealing head 46 having an annular circumferential groove 47 for receiving a sealing ring 48, for. B. an O-ring is provided.
  • This compression spring 39 presses with its first end against an underside 51 of the sealing head 46 and with its second end against an upper end face 52 of the pressure sleeve 41.
  • the bore 53 of the pressure sleeve 41 and the shaft 49 of the control piston 38 form an annular gap 54.
  • An outer diameter D41, for. B. D41 6.4 mm, the pressure sleeve 41 is adapted in the region of a shoulder 56 to the inside diameter d44 of the housing 37 in such a way that the pressure sleeve 41 is displaceably mounted in the longitudinal direction.
  • an end face 57 of the shoulder 56 serving as a stop
  • an end face 58 of a stop sleeve 59 interacts, which is fastened in the bore 44 of the housing 37 to limit the path of the pressure sleeve 41.
  • a lower end face 61 of the pressure sleeve 41 protrudes from the housing 37.
  • This control valve 36 is mounted in the right clutch disc 6 so that the end face 61 of the pressure sleeve 41 cooperates with the left clutch half 4 in the coupled state.
  • pressure medium is supplied to the working cylinder 19 via the rotary inlet 28.
  • This pressure medium flows through the line 34 to the control valve 36 and presses the cone-like sealing head 46 of the control piston 38 away from the cone-like depression 43 by the pressure which builds up, so that pressure medium flows through a resulting annular gap.
  • This pressure medium escapes through the annular gap 54 of the control piston 38 and the pressure sleeve 41 to the outside.
  • This annular gap 54 and the amount of pressure medium supplied to the working cylinder 19 are matched to one another such that a pressure builds up in the working cylinder 19 and the two clutch disks 4, 6 are pressed against one another by means of the pressure pieces 22.
  • p1 3.5 bar
  • the size of the pressure p1 is preferably 1/3 to 2/3 of the final pressure p2.
  • the cylinder is now rotated by means of an auxiliary drive, not shown, so that the two clutch disks 4, 6 pressed onto one another rotate relative to one another.
  • the pressure sleeve 41 of the control valve 36 does not touch the left clutch disc 4 and the control valve 36 remains open.
  • an electromagnetic valve can also be used.
  • This solenoid valve is controlled by means of a sensor which removes the position of the clutch disc 6.
