Definitions

  • the invention relates to a printing couple cylinder of a web-fed rotary printing press.
  • the invention relates to forme cylinders and transfer cylinders.
  • the invention has for its object to provide printing unit cylinders with which a good print quality can be achieved.
  • the printing unit cylinders can be stored without play or with little play in or on the side walls of the printing unit. You point also no sleeves that can be rotated or pushed in the side wall. These bushings can therefore be mounted in the wall without play or even clamped in the wall. Overall, good print quality can be achieved in this way. Furthermore, the eccentrics do not change their rotational position when changing the sleeve, ie when the bearing of the printing unit cylinder is exposed, ie the printing unit cylinder remains in its position unchanged when changing the sleeve.
  • a transfer cylinder 1 is shown as a printing unit cylinder, which is mounted with its pins 2, 3 in side walls 4, 5 of a printing unit.
  • the storage in the side wall 5 is not described in detail since it is not part of the subject matter of the invention.
  • the pin 2 is mounted indirectly in the side wall 4.
  • the side wall 4 has an opening 6 in the region of the pin 2, which opening is closed or exposed with sliders 7, 8 arranged on the side wall 4 and displaceable transversely to the pin 2.
  • An embodiment of such a slide is shown for example in EP 0 277 545 B1.
  • a guide 9 for the slide is indicated.
  • the slider 7, 8 take the storage 10 of the pin 2 in the drawn closed state.
  • the latter contains three rings 11, 12, 13 lying one inside the other, which are themselves supported with respect to one another.
  • the inner ring 11 is arranged on the pin 2 and mounted in the ring 12 by means of a double row cylindrical roller bearing 14.
  • the latter in turn is supported in the ring 13 by means of a double row needle bearing 15.
  • Other bearings or plain bearings can also be used to mount the rings 11, 12, 13 in one another, however, roller bearings are quite suitable for realizing a desired play-free bearing.
  • the ring 12 is eccentric and is able to shift the axis of the transfer cylinder 1 when it rotates for the printing on and off.
  • the ring 12 has a bore 16 which is eccentric to the outer jacket and in which the cylindrical roller bearing 14 is received.
  • an eccentric ring 17 is also advantageously placed between the cylindrical roller bearing 14 and the ring 12, which serves for the basic setting of the transfer cylinder 1.
  • the ring 17 is press-fitted in the bore 16.
  • the press fit is released with a hydraulic press fit, not shown.
  • the adjustment itself can be carried out, for example, by means of a threaded spindle drive familiar to the person skilled in the art.
  • the ring 17 can also be arranged in the ring 12 with roller bearings.
  • the ring 12 is designed as a sleeve 18. At the bottom of the sleeve 18, a rod 19 is attached, which in turn is rotatably mounted on the pin 2. For this purpose, it carries at its end two deep groove ball bearings 20, 21 which are received in a bore of the journal 2. Instead of the deep groove ball bearings 20, 21, other bearings can be used that can absorb an axial force.
  • the first coupling half 22 of a clutch 23 is also accommodated in the bushing 18.
  • the coupling half 22 is displaceable against the force of springs, for example cup springs 24, which are supported on the bottom of the bush 18. It is still with a parallel key 25 secured against twisting.
  • the first coupling half 22 cooperates with a second coupling half 26 fastened to the end face of the pin 2.
  • the coupling half 22 On its outer jacket, the coupling half 22 carries a circumferential groove 27 into which a shift fork 28 mounted in the bushing 18 engages with sliding blocks 29.
  • the slides 7, 8 are in the position shown in FIG. 1 and clamp the bearing 10 free of play on the ring 13.
  • the pin 2 To a rubber sleeve 31 from the transfer cylinder 1 or push it through the opening 6 of the side wall 4 to be able to, the pin 2 must be exposed in the region of the opening 6.
  • the slider 7, 8 are pushed away from the pin 2.
  • the slide 7 releases the lever 30 together with the shift fork 28, as a result of which the plate springs 24 press the clutch half 22 against the clutch half 26 and thus engage the clutch 23.
  • the clutch 23 is designed as a friction clutch, ie the mutually facing end faces of the coupling halves 22, 26 carry friction linings.
  • the clutch could also be designed as a claw or tooth clutch, for example.
  • the engaged clutch 23 has the effect that the eccentrically formed ring 12 cannot rotate relative to the transfer cylinder 1 when the rubber blanket sleeve 31 is changed, ie when the bearing 10 is exposed.
  • the latter in turn is secured against rotation by the drive with which the pin 3, not shown, is connected.
  • a rubber blanket sleeve 31, which can now be exchanged over the exposed pin 2, is shown in dash-dot lines. After the sleeve has been changed, the slides 7, 8 are moved back into the position shown. Thanks to the unchanged position of the eccentrically designed ring 12, the transfer cylinder does not change its position.
  • an actuator 32 for the ring 12 can be engaged in the latter.
  • the adjustment of the ring 12 serves, as already explained above, to switch the pressure on and off.
  • a correspondingly actuated pinion 33 which engages in a toothed segment 34 of the bushing 18, is used as the actuator 32 for this purpose in the exemplary embodiment.
  • the rod 19 also secures the sleeve 18 against displacement.
  • a driving plate 35 is provided on the ring 13, which engages in a groove 36 of the ring 12.
  • the backup could also be done otherwise, for example, that the needle bearing 15 is designed with an axial fixation.
  • a forme cylinder 37 is shown as a printing cylinder, which supports with its pin 38, 39 in side walls 40, 41 of a printing unit.
  • the bearing 42 of the pin 38 is received by sliders 43, 44 which are slidably arranged on the side wall 40 and close an opening 62 of the side wall 40 in the position shown.
  • the bearing 42 contains two rings 45, 46 which lie one inside the other and are axially displaceable with respect to one another.
  • the rings 45, 46 are embodied in the exemplary embodiment by a double-row cylindrical roller bearing 47.
  • Other rolling bearings without axial fixation, e.g. B. needle bearings, or slide bearings come.
  • the advantage of rolling bearings is that they have a good possibility of adjusting to zero play.
  • the ring 46 is fixedly arranged in a sleeve 48.
  • a bore is arranged centrally to the casing of the sleeve 48, through which a rod 49 is slidably guided.
  • Both sides of the bottom bore of the sleeve 18 are on the rod 49 compression springs 50, 51, which are supported against the bottom of the sleeve 48 and stops 52, 53 of the rod 49.
  • the rod also carries two deep groove ball bearings 54, 55 which are received in a bore of the pin 38.
  • the conditions for the deep groove ball bearings 54, 55 are the same as those of the deep groove ball bearings 20, 21 in FIG. 1.
  • the slides 43, 44 In the operating state of the forme cylinder 37, the slides 43, 44 assume the position shown in FIG. 2 and clamp the bush 48 without play.
  • the ring 45 moves relative to the ring 46 without the bush 48 having to be carried in the bore 56 of the slide 43, 44.
  • the rod 49 is displaced in the bottom of the sleeve 48 and one of the springs 50, 51 is compressed in this displacement, depending on the direction of sliding.
  • the slide 43, 44 are pushed away from the pin 38 and the bearing 42. They release the bush 48, which is pushed back into its zero position by the compressed spring 50 or 51, this spring 50 or 51 relaxing.
  • FIG. 2 (claim 7) can also be used, for example, in the printing unit cylinder according to FIG. 1.
  • the bushing 18 ' can be provided with stops 57, 58 on which compression springs 59, 60 are supported, between which the ring 13' is placed (FIG. 3).
  • the springs 59, 60 bring the ring 13' back into a zero position with respect to the bush 18 ', from which it came when the bush 18' was moved, ie when the printing unit cylinder was moved.
  • the outer ring can also be indirect, e.g. B. over an adjacent ring, be brought into a zero position for pegging, for example in that the outer ring is mounted on the adjacent ring without a degree of freedom of sliding. The device for zeroing then acts on the latter ring.
