Definitions

  • the invention relates to a cylinder of web-like material processing machines, in particular a impression roller for gravure printing machines, with a tubular jacket rotatably mounted on side bearing plates, which is penetrated by a spindle which is in the direction of rotation and has a smaller outside diameter than the inside diameter of the jacket, and thus has at least one a support bearing arranged symmetrically to the center of the cylinder and coaxially to the cylinder axis is connected, which bridges the annular space between the spindle and the casing, which is designed as a receiving space for an oil filling that at least partially occupies it.
  • a cylinder of this type is known from DE-A 31 14 731.
  • the oil filling provided here is a standing oil filling, which only serves to bring about heat compensation over the cylinder length and to prevent local temperature peaks of the cylinder jacket. It is not possible to cool the cylinder jacket and thus the jacket cover.
  • At least one heat exchanger surrounding the spindle is arranged in the annular space between the spindle and jacket, which is received on holders attached to the spindle and by means of associated spindle recesses leading, at least partially designed as flexible hose sections, connecting lines with an external coolant supply line or drain line is connected.
  • the heat exchanger is advantageously integrated into the cylinder structure.
  • An internal heat exchanger of the present type advantageously offers the possibility of largely reducing temperature differences simply by a high coolant throughput, which has a positive effect on the achievement oil temperature as uniform as possible over the entire length of the cylinder.
  • the cooling medium flowing through the heat exchanger can in this case simply be removed from a supply network which is pressurized on the supply side, for example a water supply network. A circulation system is therefore advantageously unnecessary here.
  • the heat exchanger (s) can be designed as a pipe coil or pipe coils surrounding the spindle. This results in a simple heat exchanger construction as well as a space-saving arrangement and a comparatively large effective surface.
  • two heat exchangers which are separated from one another by the support bearing or bearings can be provided.
  • This advantageously enables a structure that is symmetrical to the center of the cylinder and has an advantageous effect on achieving an oil temperature that is as uniform as possible over the entire length of the cylinder.
  • the two heat exchangers can be connected in series in terms of flow and for this purpose can be connected to one another by a connecting line which leads via a spindle recess and bridges the area of the support bearing or the support bearings.
  • a further, particularly advantageous embodiment can consist in that in a heat exchanger-free area of the annular space on the spindle, radially protruding from it and reaching into the area of the jacket, oil wipers are arranged, to which leading spindle recesses are assigned in the area of an assigned heat exchanger.
  • the oil supplied by the oil wipers to the associated spindle recesses is pumped into the area of a heat exchanger via these spindle recesses. Due to the centrifugal forces resulting from a rotation of the jacket, there is automatically a level compensation and thus an oil return.
  • the oil circuit brought about by these measures has an advantageous effect on achieving the most uniform possible oil temperature over the entire length of the cylinder.
  • connection or connection lines assigned to the heat exchangers can be along their entire length as by the assigned spindle flexible hose sections extending through recesses. This measure simplifies assembly and advantageously also results in the desired flexible connection of the coolant inlet and outlet lines to be installed in a stationary manner to the connecting lines to be installed on the spindle side, so that the mobility of the spindle is not impaired thereby.
  • the hose sections can expediently have an undersize in relation to the assigned spindle recess. This enables simultaneous use of these spindle recesses for oil circulation.
  • 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 3 which have a bore which is coaxial to the jacket bore and are mounted on side bearing plates 5 via pivot bearings 4.
  • Lifting cylinders 6 act on the end shields 5, with the aid 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 casing 2 by two support bearings 8 arranged symmetrically to the center of the press and coaxially to the preseur axis.
  • the support bearings 8 are fixed on the one hand by a spindle-side collar and on the other hand by a bushing which is provided with a split clamping ring and is clamped onto the spindle 7.
  • the support bearings 8 divide the annular space between the spindle 7 and the jacket 2 in three separate chambers 9a, 9b, 9c.
  • 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.
  • the ends of the spindle 7 projecting over the lateral bearing pins 3 are encompassed by a respectively associated closure cap 10.
  • the caps 10 are screwed to the adjacent bearing plate 5.
  • the closure caps 10 are provided with inner thrust lugs 11.
  • a movement seal arranged between the mutually facing end faces of the caps 10 and the respective adjacent journal 3 is provided, for example in the form of a sealing ring or the like.
  • the spindle ends protruding from the jacket 2, which are actuatable in the radial direction with respect to the impression cylinder axis and are designed as cylinder-piston units, and are firmly connected to the adjacent bearing plate 5.
  • the closure caps 14 are each provided with a radial bore associated with the associated sealing element 12, into which the adjusting element 12, which is associated with the spindle end encompassed thereby, engages in a plunger-shaped manner.
  • the actuators 12 engaging in the radial bore of the adjacent cap 10 plunger 13 ordered, at the outer end of which the piston rod of the actuator 12 in question forms the cylinder-piston unit.
  • the annular space 9 is provided with an oil filling which partially occupies it and which in turn is continuously cooled.
  • connection lines 15 on the press side are connected to a stationary coolant supply line 16 or coolant discharge line 1'7 arranged outside the impression line.
  • the connecting lines 15 run in recesses provided on the spindle side.
  • two heat exchangers 14 are provided, which are accommodated in the two outer annular chambers 9a and 9c. These two heat exchangers 14 can be connected in parallel in terms of flow. In the exemplary embodiment shown, the two heat exchangers 14 are connected in series in terms of flow. For this purpose, the heat exchangers 14 are through the middle one the support bearing 8 limited annulus 9b bridging connecting line 18 interconnected. The connecting line 18 runs in an associated spindle recess, so that no collisions can occur in the region of the support bearings 8. In the area of the middle annular chamber 9b, blades 19 are provided which are attached to the spindle 7 and protrude radially therefrom and extend with their outer end into the area of the jacket 2.
  • the blades 19 are arranged in the region of further spindle recesses which connect the regions of the annular space 9 assigned to the blades 19 to the regions of the annular space 9 assigned to the heat exchangers 14 in terms of flow.
  • the oil stripped from the blades 9 and directed radially inward is thus pumped into the areas of the annular space 9 assigned to the heat exchangers 14. Due to the level compensation resulting from the centrifugal force, the oil automatically flows back via the support bearings 8, which are designed here as roller bearings. This: oil circulation results in a good temperature compensation and at the same time ensures good bearing lubrication.
  • the connecting lines 15 and the connecting line 18 can simply be designed as flexible hose sections laid in the associated spindle recess.
  • the flexibility of the hose sections makes it easier to move them into the assigned spindle recess.
  • the hose sections forming the connecting lines 15 and the connecting line 18 have an undersize in the illustrated embodiment compared to the clear width of the respectively assigned spindle recess. This ensures that the oil circulation caused by the blades 19 can lead via the spindle recesses associated with the connecting line 18 and / or the connecting lines 15, which are provided with radial branches 20 opening out in the area of the blades 19.
  • the recesses of the spindle 7 are formed in the illustrated embodiment in the form of a centrally arranged, axial through bore 21, from which radial and radial openings in front of and behind each heat exchanger 14, for receiving the heat exchanger-side end region of the connecting lines 15 and the connecting line 18, serve as tube sections 22 and the radial bores 20 forming the branches 20 assigned to the blades.
  • the radial bores 22 assigned to the connecting lines 15 and the connecting line 18 are arranged inclined to the spindle axis, which facilitates the insertion of the hose sections forming the connecting lines 15 and the connecting line 18.
  • the spindle recesses could be designed as line sections, so that only connecting pieces leading away from the end cross sections of the spindle recesses would be required.
  • the use of hose sections laid in the spindle recesses simplifies the manufacture of the spindle recesses and the line assembly.
  • mounting brackets 23 which are provided with a connecting sleeve 24, on the one hand the respective adjacent end of a heat exchanger 14 and on the other hand the associated end of a connecting or connecting line 15 or 18 can be fixed by screw cap.
  • the hose sections protruding from the axial bore 21 in the area of the spindle ends and forming the connecting lines 15 are screwed to the coolant supply line 16 or coolant discharge line 17 in the area of the sealing caps 10.
  • connecting sleeves 25 inserted into the sealing caps 10 are provided. The ends of the hose sections 7 projecting beyond the spindle 7 ensure the mobility required as a result of the spindle deflection.
  • Water can be used as a coolant. Cooling water is available in many printing plants in the form of a network that is pressurized on the supply side and fed from a central cooling station. Where this is not the case, water taken from the normal water supply network can simply be used.
  • the coolant supply line 16 is accordingly designed as a branch line of such a supply network 26: the network pressure is sufficient to ensure a proper coolant flow in the area of the heat exchangers 14.
  • the coolant discharge line 17 opens into a drain pipe 27 which leads back to the central cooling station or, if tap water is used, opens into the normal sewage system.
  • a term is in the area of the coolant drain line 17
  • Statically controllable throttle valve 28 is provided, which regulates the coolant throughput as a function of the coolant temperature or, as here, expediently as a function of the oil temperature.
  • a sensor 29 that detects the oil temperature is provided.
  • an oil expansion tank 30 is provided outside the impression cylinder and is connected to the annular space 9 via a spur line 31.
  • the stub 31 is screwed to a connecting piece arranged in the area of a closure cap 10.
