Definitions

  • the invention relates to a device for height adjustment of rollers, in particular rollers arranged one above the other in supercalenders and smoothing units, according to the preamble of claim 1.
  • the nut has a toothing on its circumference, which can optionally be brought into engagement with a gearwheel which can be rotated counter to the hanging spindle. If this intervention exists, the nut is turned in synchronization with the hanging spindle.
  • the bearing housing therefore maintains its altitude. If the gearwheel is disengaged from the toothing of the nut by axial displacement, the nut does not rotate when the suspension spindle rotates, so that it performs a vertical movement together with the bearing housing.
  • a gap adjustment device described in DE-OS 18 11 214 consists of hydraulic or mechanical coupling elements arranged between two successive roller bearing housings, which automatically adjust to the center distance when the rollers move together by locking means and extend automatically by the amount of the adjustable gap height when the rollers are raised .
  • the implementation of this proposal is associated with increased effort.
  • the invention has for its object to provide an uncomplicated device for height adjustment of rollers arranged one above the other, which allows the roller distances to be increased simply and quickly and to restore them even after changing a roller with a different diameter.
  • the object was achieved by the device described in claim 1, the subclaims containing special embodiments.
  • the device which consists of a few parts, ensures that it is quick and easy Increasing the roller spacing in that when lowering the lifting units assigned to the bottom roller or lifting the threaded spindles via the corresponding lifting units, the rollers lying above the roller spacing to be increased are blocked in their movement along the threaded spindles in the direction of the weight force and the ones below, if necessary , released. This can be achieved via the contact piece that determines the minimum distance between the nut and the housing. If the minimum distance allows the gears to mesh, this prevents movement in the corresponding direction.
  • the original roller spacing is achieved even after the installation of a roller which differs in diameter in that the rollers are raised via the lifting units of the lowest roller or lowered via the threaded spindles, the position of the switching element making it possible for the teeth to mesh.
  • the associated blocking of the movement of the rollers occurs when the lifting units of the bottom roller are slightly lowered after reaching a certain height or the threaded spindles are raised slightly.
  • Both exemplary embodiments have in common that the rollers 1 arranged one above the other are mounted in bearing housings 2, which are connected to the roller frame 5 so as to be displaceable in height by means of a guide slide 3 and a sliding guide 4.
  • bearing housings 2 which are connected to the roller frame 5 so as to be displaceable in height by means of a guide slide 3 and a sliding guide 4.
  • each guide carriage 3 and the roller frame 5 via a threaded spindle 7 with nut 8 without self-locking as well as a housing 9 enclosing the nut 8 and partially the threaded spindle 7 and axially displaceable thereon.
  • the latter has a toothing 11 on the end face 10 which is opposite to the axial displacement direction 12 of the nut 8 when loaded by the roller weight.
  • the housing 9 also has a toothing 13 and a movable contact piece 14 on the inner surface opposite the toothed end face 10 of the nut 8.
  • This contact piece 14 defines the minimum distance between the nut 8 and the housing 9 and can take the form of a ring arranged around the threaded spindle 7 and displaceable thereon.
  • the switching piece 14 should be rotated with the aid of a conventional adjusting device around the threaded spindle 7 in a defined manner and the relevant inner surface of the housing 9 and the opposite end face 15 of the annular switching element 14 should be designed in such a way that the switching element 14 can be rotated into one of the surrounding side surfaces of the housing 9 protruding height can be brought, which is on the one hand to release the rotational movement of the nut 8 at least as large as the protruding teeth 11 and 13 of the end face 10 of the nut 8 and the inner surface of the housing 9 together or on the other hand the meshing of the teeth 11 and 13 and so that the locking of the nut 8 allows under load in the direction of the weight of the rollers 1. This presupposes that the distance between the two end faces 10 of the nut 8 and the inner faces of the housing
  • a controllable lifting element 16 is located below the pivot point between the bearing housing 2 and the guide carriage 3.
  • Characteristic of the embodiment shown in Fig. 1 is that the Guide carriage 3 are firmly connected to the corresponding housing 9 and the nuts 8 are each arranged together on a threaded spindle 7 fastened to the roller frame 5.
  • the height adjustment of the rollers 1 can thus take place via a lifting unit 6 assigned to the bearing housings 2 of the lowermost roller 1, or a lifting unit 6 ′ which effects the height displacement of the threaded spindles 7.
  • the guide carriage 3 with the corresponding threaded spindle 7 and the housing 9 are pivotally connected to the roller frame 5.
  • a bearing unit 6 is assigned to each of the bearing housings 2 of the lowermost roller 1.
