Definitions

  • the invention relates to a roll stand with at least two corresponding rollers that are movably guided relative to one another in bilateral bearing arrangements, one roller being displaceable relative to the other by means of an adjusting mechanism for the purpose of adjusting the resulting roller gap.
  • the coating material is brought to the metering roller gap from a feed trough 105 which extends over the bale or coating width of the installation and is continuously transported to the film 106 via the roller system.
  • the decisive for the layer thickness roll gap above the feed pan 105 is formed with the help of the on the stand frame 107 with the pillow block 107 'fixed application roller 102 and on a load support bearing 108 on the stand 107 guided dosing roller 101.
  • the size of the nip or the thickness of the more or less consistent material transported to the film can be adjusted with the aid of a screw spindle 110 articulated on the bearing slide 109 and an adjusting device which is mounted on the stand 107 and consists of nut 111 and fork bracket 112.
  • a screw spindle 110 articulated on the bearing slide 109 and an adjusting device which is mounted on the stand 107 and consists of nut 111 and fork bracket 112.
  • the inner ring tolerances of the radial bearings 108, 107 ' have a full effect on the nip accuracy, even in the case of a version free of play.
  • FIG. 1 the inner ring tolerances of the radial bearings 108, 107 'have a full effect on the nip accuracy, even in the case of a version free of play.
  • the roller gap formed by the roller pair 101, 102 and the roller axis spacing defined by the roller axes 101 ′, 102 ′ is thanks to the non-positive and form-locking, mutually braced connecting elements of an adjusting and supporting device 113, 114, 115, 116 unaffected by disturbances which are caused, for example, by inaccuracies in the roller support bearings 107 ', 108 in FIG. 1 and / or by deflections exerted by the spindle couplings on the roller journals.
  • the roller actuating unit consisting of the piston rod bearing 115 and the cylinder block bearing 116 guides the roller gap to zero in terms of operation
  • the support unit consisting of the pair of support bearings 113, 113 'acts with pressure screws (spring elements) and adjusting gear housing 114 in the Support plane xx opposite.
  • the roller journals become claimed to a certain extent on bending, which is generally undesirable. 3 those bending lines of the roller axes 101 ', 102' generated by the arrangement of the adjusting and supporting elements according to FIG. 2 are shown exaggerated.
  • Fig. 4 shows a novel placement of the aforementioned actuating / support units, which is characterized by an arrangement lying in a common radial plane yy of the roll neck in the manner of a mutually interpenetrating construction of the actuating and supporting elements.
  • the roller journals 121, 122 of the metering and application roller 101, 102 are also gripped here in a known manner with the aid of an actuating and supporting unit and guided autonomously.
  • the actuating unit consists essentially of the bearing half-shell 131, 132 with four anchor bolts 133 held and guided by it and the actuating cylinder block 134 connected to it, together with the actuating piston 135 and the piston plate 136 and the identical anchor bolts 133 'screwed to it in the same way on the opposite side, which also with the help of an identical bearing half-shell 131 'closes the force circuit via the roller pin 122 on the other side of the application roller 102.
  • the actuating unit designed in this way counteracts the support unit installed between the roller journals 121, 122, which essentially consists of the other pair of play-free bearing halves 141, 141 'arranged on the "inner" opposite side of the journals 121, 122 and the compression spring bars 143.
  • a sectional view jj Fig. 4a of the adjusting / supporting elements according to FIG. 4 makes it clear that the adjusting and supporting elements of the construction are interlocked and positively guided in such a way that their centrally centered adjusting or supporting forces are always in the same radial plane yy of the roll neck 121, 122 attack.
  • FIG. 4b A variant of the arrangement shown and explained in FIG. 4 / 4a of the roller composite system consisting of actuating and support units is shown in FIG. 4b.
  • the roller journals 121, 122 are pressed apart with the aid of the compression springs 143 in connection with the pair of bearing half-shells 141, 141 'against the actuating unit 131, 131', 133, 134, 135, 136 and how in the case of Fig.
  • the actuating piston 135 of the actuating cylinder block 134 is hollow and takes on two tasks, namely the actual one as an actuator and a second one for guiding a displacement measuring device 161, 162, 163, 164, 165.
  • One in the piston 135 is free and independent of its actuating direction with the help of a longitudinal bearing 139 in a tappet housing 162 embedded and guided displacement sensor 161 is supported by means of a compression spring 163 and stops 164, 165 on the support bearing half-shells 151, 151 'which are supported on the roller journals without play.
  • the roll spacing or (in the case of a centrically ground roll roll) the roll gap which is proportional to it can be measured in a reliable manner or controlled with the aid of a control device comprising a setpoint / actual value comparator 167, 168 and a servo valve 130; see Fig. 7.
  • a control device comprising a setpoint / actual value comparator 167, 168 and a servo valve 130; see Fig. 7.
  • a valve-free actuating force control practiced with the aid of a regulating pump 138 can be used.
  • a more precise actuating force control will, however, use a suitable servo valve 130, a pressure measuring device 166 and a comparator 167, 168, as indicated in FIGS. 5 and 7.
  • three alternative sensors are available as actual value transmitters, namely one each for a roller distance measurement 161 and signal pressure measurement 166 and, as a further variant, an actuating force measurement with the aid of a load cell 147.
  • the compression spring bars 143 are supported indirectly by means of an intermediate plate 146 via the load cell 147 on the support bearing half-shell 141 '.
