Definitions

  • the invention relates to a cylinder for web-like material processing machines, in particular a impression roller for a rotogravure printing machine, which is accommodated in the area of its ends in adjustable end shields and has a tubular jacket provided with a rubber cover, which is in the direction of rotation, one with respect to the inside diameter of the jacket penetrated smaller outside diameter, hereby connected via at least one support bearing arranged symmetrically to the jacket center and coaxial to the jacket axis and independent of the spindle passing through it through pivot bearings arranged in the region of its ends on the
  • Lateral bearing plates is supported, on each of which an actuator that is actuated in the radial direction and engages the respective end of the spindle that projects over the jacket and is actuatable with respect to the spindle is supported.
  • a cylinder of the type mentioned is known from DE-OS 30 33 230.
  • An arrangement of this type has proven itself in itself.
  • Experience has shown, however, that flexing within the rubber cover can lead to a high rubber core temperature, which is above the permissible limit in particular at high speeds and therefore has a negative effect on the life of the rubber cover.
  • Remedy could u. U. bring a reduction in line pressure and thus a reduction in flexing.
  • this is normally not possible for printing reasons, since a minimum line pressure is also required when using electrostatic printing aids or the like.
  • there is therefore a limitation of the permissible speed which is below the speed required today of 50,000 revolutions per hour.
  • the spindle in the region of each support bearing can have at least one bore opening in front of or behind the respectively assigned support bearing into the annular space between the spindle and the jacket and forming the bypass line.
  • This is a particularly simple design of the bypass line. This can be an oblique through hole or an angled hole.
  • a further, particularly expedient further development of the superordinate measures can consist in the fact that the actuating members each have a plunger engaging in the radial bore of the respectively assigned sealing cap, which plunger abuts the associated spindle end and is supported by its end facing away from the spindle on the piston rod of one on the adjacent bearing plate Cylinder-piston unit is present.
  • the only figure of the drawing shows a longitudinal section through an impression roller according to the invention for a gravure printing machine, which is included in a cooling circuit.
  • the impression roller on which the drawing is based consists of a tubular jacket 2 provided with a rubber cover 1, which is provided in the region of its ends with lateral bearing supports which have a bore which is coaxial to the jacket bore and are rotatably mounted on side bearing plates 5 via pivot bearings 4.
  • Lifting cylinders 6 act on the end shields 5, by means of which the impression roller can be placed or pressed against the respectively assigned cylinder or lifted off the latter.
  • a spindle 7 extending through it and rotating in the direction of rotation, the outside diameter of which is smaller than the inside diameter of the jacket bore or the bore of the bearing socket 3.
  • the spindle 7 standing in the direction of rotation is connected to the jacket 2 by support bearings 8 arranged symmetrically to the jacket center and coaxially to the jacket axis.
  • the support bearings 8 are fixed on the one hand by a collar on the spindle side and on the other hand by a bushing 10 which is provided with a split clamping ring 9 and is clamped onto the spindle 7.
  • the spindle 7 is longer than the jacket 2 provided with the lateral bearing neck 3, so that the ends of the spindle 7 protrude beyond the ends of the bearing journal 3 and thus of the jacket 2.
  • actuating elements 11 which can be actuated in the radial direction with respect to the spindle or jacket axis and which are firmly connected to the respectively adjacent bearing plate 5, as indicated in the drawing by a screw connection is.
  • the annular space 12 between the jacket 2 and the spindle 7 is included in a coolant circuit which is supplied with a cooling medium, expediently oil, via a cooling unit 13.
  • a cooling medium expediently oil
  • the cooling oil that passes through the annular space 12 and fills it is subjected to a strong swirling due to the rotation of the jacket 2, which causes reliable heat transfer and a strong temperature compensation even over the length of the impression roller.
  • the ends of the spindle 7 projecting beyond the lateral bearing pins 3 are each associated with a closure cap 14 includes.
  • the caps 14 are provided with connection bores 15 for the flow load 16 and the return load 17 of the coolant circuit leading over the cooling unit 13.
  • the caps 14 are screwed to the adjacent bearing plate 5.
  • the closure caps 14 can be provided with inner thrust lugs 18.
  • a movement seal in the form of a sealing ring 19 is provided between the mutually facing end faces of the caps 14 and the respectively adjacent journal 3.
  • a bypass line 20 is provided in the region of each support bearing 8.
  • the spindle 7 is provided with an angled bore for this purpose, which opens into the annular space 12 in front of and behind the respectively associated support bearing 8.
  • an oblique through hole could also be provided to form the bypass line 20, as indicated in the drawing by dashed lines.
  • the lines for forming the forward branch 16 and the return branch 17 can be designed as tubes or hoses.
  • the line forming the return branch 17 opens into a reservoir 21 into which the suction nozzle of a pump 22 which acts on the cooling unit 13 is immersed.
  • An operating monitoring device for example in the form of a sight glass, etc., is assigned to the pump 22. It would also be conceivable to design the operational monitoring device 23 in such a way that if the pump is not operating, the impression roller cannot be started or is automatically brought to the pressure stop.
  • the temperature in the area of the forward branch 16 is kept constant at an adjustable value.
  • the oil temperature in the forward flow 16 is measured by means of a sensor 24 and a controller 26, which interacts with an adjustable setpoint generator 25, is fed in, by means of which the flow of cooling water through the cooling unit 13 designed as a heat exchanger can be regulated.
  • the cooling water line 27 of the cooling unit 13 is provided with a shut-off element 28 which can be adjusted by the controller 26.
  • the cover caps 14 are each provided with a radial bore 29 through which the adjusting element 11, which is associated with the spindle end encompassed thereby, engages in a plunger-shaped manner.
  • one or more circumferential sealing rings 30 are provided in the area of the radial bores 29.
  • the piston rod of a cylinder-piston assembly forming the relevant actuator 11 could engage directly in the respectively assigned radial bore 29 of the adjacent cover caps. With an arrangement of this type, however, it would be necessary to disengage the piston rod from the radial bore 14 in the event of removal of the cover cap 14.
  • the actuators 11 therefore consist of the radial bore 29 of the two cover caps 14 End plunger 32 and cylinder piston assemblies 34 assigned to each of them, the piston rod 31 of which ends radially outside the adjacent cover cap 14 and is in operative connection with the plunger 32 which engages in an associated radial bore 29 and which has its radially inner end on the spindle 7 and rests with its radially outer end on the associated piston rod 31.
  • the plungers 32 separated from the cylinder-piston assemblies 34 can accordingly remain in their engagement position in the respectively assigned radial bore 29 even in the event of a reassembly of the respectively assigned cover cap 14.
  • the tappets 32 are provided on the spindle side with a spherical end face which rests on a flat 33 of the respectively associated spindle end.
  • the support bearings 8 are designed as roller bearings.
  • the support bearings 8 are designed as slide bearings which, due to the hydrodynamic lubrication conditions, are subject to particularly low friction during operation and have excellent damping properties.
