Definitions

  • the invention relates to a calender for web-shaped Materials, such as paper, with a stand and a roll stack, the one lower roll, one upper roll and at least one intermediate roller arranged between them having.
  • Such a calender is known from DE 30 04 913 C2.
  • the rollers are arranged in a vertical stack.
  • the top and bottom rollers are bending adjustment rollers with jacket lift.
  • the lower roller is on a hydraulic cylinder supported, which together with the jacket stroke of Lower roller has a sufficiently large lowering path for cutting the rolls result from each other. With this lowering movement the stops of the individual rollers come one after the other on adjusting nuts of hanging spindles for support, which means that the individual roll nips in succession and after going through a correspondingly large one Are separated from each other.
  • the invention has for its object a calender of the type described in the introduction, in which the separation of the rollers can be done particularly quickly.
  • At least one middle roller for the purpose of roller separation relative to the neighboring roller in an approximately perpendicular to the stacking plane transverse direction is displaceable.
  • the bottom roller for the purpose of roller separation lowerable in the stacking level and the bottom middle roller is transversely displaceable. Because of this lowering the center roller can make its transverse movement even faster To run.
  • Another advantage is that the lowering movement the bottom roller can be kept very low, whereby the size can be significantly reduced.
  • the stacking plane is horizontal is inclined and the at least one transversely displaceable Center roll obliquely down from the stacking level is movable. Due to the inclination of the stacking level is both the lower roller to be lowered and the at least one transversely displaceable center roll by one Force component in the desired direction of movement loaded so that the opening of the nips takes place even more quickly goes.
  • the at least one Transversely displaceable center roll through hydraulic cylinders is relocatable.
  • the bearings of the least a cross-shiftable center roller of levers are carried, which can be pivoted about pivot axes on the stand are and that the bearings relative to the levers or the levers relative to the pivot axes or the pivot axes relative to the stand by the hydraulic cylinders are adjustable.
  • the bearings relative to the levers or the levers relative to the pivot axes or the pivot axes relative to the stand by the hydraulic cylinders are adjustable.
  • At least one is expediently displaceable transversely Middle roller a hard roller.
  • the soft rollers that have to be changed frequently during operation then slightly from the free side of the stack accessible.
  • top middle roller is stably mounted.
  • the top roller can then pass through Lifting simultaneously with lowering or moving sideways the remaining rollers from the roller underneath be separated.
  • At least a center roller is carried by levers that move around Swivel axes on the stand are pivotable and that the Lever stops are assigned to the lowering movement stop the center roller.
  • the opening width of the Nips is therefore determined by the swivel paths of the levers and - in the case of the cross-shiftable center rollers - through the cross shift.
  • bottom middle roller is transversely displaceable and that the lower roller also is transversely shiftable to a single work nip to form with roller nips open otherwise.
  • Man can therefore use the same calender for calendering (using all roller nips) and for matting (using only the lowest gap).
  • the calender illustrated in Fig. 1 has one Stand 1 on a floor 2 and a raised Podium 3 is supported. Has a roll stack 4 eight rollers 5 to 12, whose center lines in a stacking plane 13 lie at an angle of about 45 ° runs to the horizontal.
  • the top roller 5 is a bending adjustment roller with a rotatably held on the stand 1 support 14, on the a roller jacket with limited stroke via hydraulic Supports.
  • the top middle roller 6 is a hard roller. Your camp 15 is fixedly mounted on the stand 1.
  • center rolls 7 and 8 are soft rolls and attached to levers 18 and 19 with their bearings 16 and 17, about pivot axes 20 and 21 on stand 1 can pivot.
  • the middle roller 9 is a hard roller, the bearing 22nd is supported by a lever 23 which is about a pivot axis 24 is pivotable.
  • the middle roller 10 is a soft roller, the bearing 25 are carried by levers 26 which are about pivot axes 27 are pivotable.
  • the lowest center roll 11 is a hard roll
  • the Bearings 28 are carried by levers 29 which are arranged around a Pivot axis 30 are pivotable.
  • the lower roller 12 is in turn a bending adjustment roller with a jacket with limited stroke.
  • the coat is via hydraulic support elements on a turning test held Supported 31.
  • the construction of such bending adjustment rollers results from DE 30 04 913 C2.
  • the middle rollers 7, 9 and 11 can cross to the stacking level 13 can be moved out.
  • the Hebei are 18, 23 and 29 each with the help of a hydraulic motor 32, 33 and 34 relative to the pivot axis 20, 24 and 30 adjustable on guides not shown.
  • the lower roller 12 is adjustable transversely to the stacking plane 13, for what purpose a hydraulic motor 49 between carrier 31 and stand 1 is provided.
  • Stops 36 to 40 are the individual levers of the center rollers assigned and determine their end position. So the lowest nip 41 is from the stroke of the jacket of the Bottom roller 12, the stop 40 and the way in the direction of arrow D determined.
  • the size of the nip 42 depends on the stops 39 and 40 and the path towards the Arrow D from.
  • the size of the nip 43 results from the Location of the stops 38 and 39 and the size of the Path in the direction of arrow C.
  • the nip 44 results by the location of the stops 37 and 38 and the latter Path.
  • the nip 45 is through the stops 36 and 37 and the path in the direction of arrow B are determined.
  • the nip 46 results from the position of the stop 36 with reference to the fixed center roller 6.
  • nip 47 results from the stroke in the direction of arrow E, which the jacket of the top roller 5 performs. All opening movements can largely done simultaneously.
  • For adjusting the hydraulic cylinders 32 to 34 as well as the coats of the top and bottom roller are relatively small amounts of hydraulic fluid and a relatively low pressure is required. You can therefore all connections with hydraulic Execute standard pipes and connections and required no expensive and very large hydraulic components.
  • FIG. 3 differs from FIG. 2 only in that that the carrier 31 of the lower roller 12 using the hydraulic cylinder 38 around the path according to arrow F approximately is displaced perpendicular to the stack plane 13. Now if the nip 41 is closed, it forms a working nip, while all other nips 42 to 47 are open. You can therefore use a matt treatment instead of a satin finish carry out.
  • the bearing block carrying the bearing 122 is over one Swivel bearing 148 guided on lever 123. 4 is the stretched position is shown for normal operation, 5 the kinked position for the roller cutting operation, where the bearing axis has a smaller distance of the pivot axis 124 than in the stretched state.
  • stops 138 ensure that a defined one End position results.
  • the embodiment shown can be in multiple Terms are deviated without the basic idea to leave the invention.
  • the top middle roller 6 like the other middle rollers a lever can be mounted if one of the end rollers 5 or 12 of the roller jacket moved up to a stop and with the help of the jacket of the other end roller the Nip load is set.
  • the hard rollers 6, 9 and 11 are preferably heated.
  • the center rollers 7, 8 and 10 can have an elastic cover, but also the top and bottom rollers 5 and 12.
