Definitions

  • the invention relates to a device for guiding rolls of a substantially vertical calender, wherein to compensate for overhanging loads at each roll end of a roll a movable lever-like part containing the roll bearing is provided, which is essentially vertically pivotable, the pivot axis parallel to the axis of the roll and on which acts a force element which is able to apply the force necessary to compensate for the overhanging loads and, if necessary, to let this force no longer act so that the roll can be lowered, with each roll end on the stand of the calender vertically adjustable essentially vertically guided, in the set position by means of an adjustable positioning device fixable base part is assigned, in which the movable part, on which the bearing of the roller end is located, has its pivotable bearing point, the relative mobility between The base part and the movable part are so restricted that the downward movement of the roller can thereby be limited.
  • the force element is supported in each case on the base part, which is on the frame of the calender is movable. If the diameter of one or more rollers changes, for example by regrinding, the adjustment is carried out with adjusting screws by changing the position of the base part. This is usually cumbersome and lengthy.
  • the aim of the invention is to provide a device in which the adjustment of the position takes place with few parts and with simple, manageable means, so that savings can be made without any significant disadvantages. Furthermore, the adjustment should be easy to carry out and, if necessary, be possible by motor.
  • An adjustable stop can be arranged between each base part and the movable part, against which the movable part is supported when the calender is open when the roller is lowered.
  • the device for compensating overhanging loads is simultaneously suitable for the rapid opening of the calender, with the moving parts moving apart with the rollers.
  • the force element is in the opposite sense can be actuated to form the relief force.
  • the base part is lifted off the adjusting ring when the rollers are touching, so that it can rotate with the threaded spindle and is not adjusted.
  • the force element can be dimensioned to apply a force exceeding the weight of the roller, an adjustable stop being arranged between the base part and the movable part, by means of which the movement of the movable part is limited when the roller is lifted upwards. This gives the possibility of opening the calender by moving the rollers upwards.
  • the movable part can be in the form of a one-armed lever, the force element acting between the axis of rotation and the roller bearing. This results in an embodiment which takes up little space and does not pose any problems when placed on the calender frame.
  • the movable part can also have the form of a two-armed lever, the force element acting on the arm of the lever facing away from the roller bearing.
  • This arrangement has the advantage that it can require lower forces of the force element.
  • the force element can preferably be a cylinder-piston device which can be acted upon by suitable pressures with hydraulic or gaseous medium.
  • the calender shown in Figures 1 and 2 of the drawing has a frame 1, on which a vertical sliding guide 2 is formed.
  • Two pressure cylinders are arranged along the slide guide 2, a lower 3 with a piston 4 and an upper pressure cylinder 5 with a piston 6.
  • the lower pressure cylinder 3 is shown free-standing, while the upper pressure cylinder 5 is fixed to the slide guide.
  • Base parts 7 are arranged on the slide guide 2, in which lever-like movable parts 10 are mounted on pins 8, each of which carries a bearing 11 of a roller 12 or 13 at its ends.
  • the rollers 12 located at the ends are preferably deflection-compensating rollers, while the intermediate rollers 13 are hard or soft rollers in a known manner as required, which rollers have to be reground periodically.
  • the movement of the movable part 10 is limited downwards by an adjustable stop 14, upwards by an also adjustable stop 14 '.
  • the movable part 10 is under the influence of a force element 15, in this case a cylinder-piston device, which can be connected by supply lines 16, 17 to a source of hydraulic pressure medium or a pressure of suitable pressure.
  • a vertical threaded spindle 18 with a motor drive 20 is provided, on which adjusting rings 21 are screwed, each ring being one Base part 7 is assigned.
  • the setting rings 21 form vertically adjustable stop parts on which the corresponding base part rests during operation.
  • FIGS. 3, 4 and 5 show different embodiments of the base parts 7 with the movable parts 10.
  • FIG. 3 corresponds to an enlargement of the embodiment according to FIGS. 1 and 2.
  • FIG. 4 shows an embodiment in which the base part 7 lies completely in front of the frame 1.
  • the force element 15 is located between the pivot axis of the movable part 10 given by the pin 8 and the roller bearing 11 or the roller axis A.
  • the movable part 10 has the shape of a two-armed lever, with pins 8 arranged in its central region, the force element 15 acting on the arm of the lever facing away from the roller bearing 11.
  • the rollers are in the position in which they press against one another and roll a material web (not shown).
  • the adjusting rings 21 are set on the threaded spindle 18 so that the base parts 7 supported by them are in a position in which the movable parts 10 run essentially horizontally.
  • the force elements 15 thereby develop an upward force, which the overhanging loads, i.e. balances the weight of the bearings 11 and any parts attached to them. As a result, the rollers are essentially kept free from bending influences of these loads.
  • the force elements 15 are dimensioned to apply a force that exceeds the weight of the respective roller.
  • the upper pressure cylinder 5 is depressurized, the piston 6 being drawn in.
  • the force elements 15 are exposed to a higher pressure by the supply line 17 than what is required to compensate for the overhanging loads, so that they hit the upper stops 14 '.
  • the adjusting rings 21 can in principle be brought to the correct height by hand.
  • the threaded spindle 18 can preferably be driven by a motor, the adjusting rings 21, on which the base parts 7 rest, being held in place by friction or by an external device and being unable to rotate with the threaded spindle 18. They are therefore moved either downwards or upwards along the threaded spindle.
  • the sliding guide 2 of the base parts 7 are replaced by parallel links or a similar lever arrangement.
  • the base parts can be fixed using cables or chains that can be adjusted using rollers or pinions.
  • a gear movable along a vertical rack or chain is also conceivable.
  • the stops 14, 14 ' can be replaced by hydraulic stops and combined with the force element, as described in German patent application 36 40 161.
  • the opening speed of the individual rollers in terms of size as well as the course can e.g. can be controlled by throttles, so that e.g. hard hitting is avoided.
  • the force element 15 also need not be a cylinder-piston device, but e.g. a pressure chamber made of elastic material like a bellows. Also magnetic or mechanical elements e.g. Feathers are conceivable.
