Definitions

  • the invention relates to a continuous press for pressing pressed material mats into pressed material boards in the course of the production of chipboard, fiberboard and other wood-based panels, with press lower part and press upper part, in the press lower part and press upper part, endlessly rotating steel press belts, and with an inlet mouth, wherein a heatable press plate is arranged in the lower press part and in the upper press part and adjoin the press plates protruding heatable inlet plates to form the inlet mouth, furthermore the steel sheet press belts are supported on the press plates and inlet plates with the interposition of rolling elements, in addition a device for adjusting the Inlet mouth and at least one device for adjusting the inlet contour of the inlet mouth are provided.
  • Such a press is known in which the Device for setting the inlet contour one Has contour slide on one of the concerned Guide plate associated press spar guided and with With the help of an inlet contour actuator in the inlet direction is adjustable.
  • the inlet contour slide points to Inlet plate a plurality of transverse to the direction of entry trending steps that one belong to the contour-defining support staircase.
  • Of the Support stairs are assigned at least one counter bar, which is connected to the inlet plate in question.
  • the counter bar can be selected against one of the levels of Support stairs can be created.
  • the Inlet edges of the inlet mouth to different adjust operational conditions.
  • it is Adjustment of the bending lines of the inlet plate concerned only gradually and consequently in limited areas possible, with only a trumpet-shaped Enema mouth can be realized (see. DE 44 33 641).
  • a continuous press is also known at which is the top of the two heated inlet plates divided into plate sections to form joints is, so that the inlet contour of the inlet mouth in the Hinge areas has kinks. This also applies to the transition area between the upper inlet plate and the subsequent upper press plate.
  • This known embodiment is by means of hydraulic Actuators only the angular position of the plate sections adjusted around the axes of rotation of the joints. Especially problematic is the fact that the assigned Sheet steel press belt when driving over the kinks experiences corresponding bends and consequently one is subject to immediate wear and tear (see DE 195 18 879).
  • the invention has for its object a continuous Press the described above
  • To create embodiment in which the Inlet contour of the inlet mouth is stepless under generation can set any continuous bending lines and even an almost parallel position from the top inlet plate and lower inlet plate up to the neutral zero line of the press inlet also for pressing extremely thin pressed material mats to perfect pressed material plates under Consideration of high production speeds is adjustable.
  • the invention solves this problem with a generic one continuous press in that the device for Setting the inlet contour a plurality of Cylinder piston assemblies that the cylinder piston assemblies in a predetermined distribution on the one hand to the upper and / or lower inlet plate, on the other hand to the Upper press part and / or lower press part are articulated, and that the cylinder piston assemblies to a computer-controlled or -controlled hydraulic system connected are.
  • the cylinder piston arrangements are preferably around double-acting differential cylinders.
  • the upper inlet plate has a bending radius to the effect that between the upper Inlet plate and the lower inlet plate an almost Parallel position is reached, which extends up to extends below the neutral zero line of the press inlet. Almost parallel location means that a slight taper for running in and lightly clamping the relevant Pressed mat is set.
  • the enema mouth or his Inlet contour can also within the scope of the invention as before for the production of thick pressed boards in the previous mode of operation set trumpet-shaped be such that the compression from above and done almost evenly at the bottom. -
  • the setting of the Inlet contour depends on the pressing mats and especially the mat thickness.
  • the mat values for the suitable bending lines or Bending radii of the upper and, if necessary, lower inlet plate can be done using a conventional path measurement technique record and send it to a computer.
  • This calculator determines the necessary correction values and influences the hydraulic control or regulation of the differential cylinder in such a way that the inlet plate in question or plates in the desired by tensile and compressive forces Be brought into shape.
  • the differential cylinders are preferred in longitudinal rows and possibly transverse rows on the top and / or articulated lower inlet plate and have the inlet plates in the longitudinal direction of the board or in the direction of entry running channels for the heating medium.
  • the invention is based on the knowledge that longitudinally drilled inlet plates in the course of adjustment the bending lines or bending radii of the differential cylinders generated bending moments as opposed to transverse drilled inlet plates taking into account the occurring voltage states take up much cheaper can.
  • the invention provides that the Differential cylinder gimbal on the upper and / or lower inlet plate and on the press top and / or Press lower part are hinged, and that the articulation of the Differential cylinder on the upper and / or lower Inlet plate with thermal insulation is made.
  • the gimbals Joints of the differential cylinders with interposition supported by insulating material against the inlet plates be in turn, with the interposition of Thermal insulation on frame parts of press top and Press base can support.
  • the Hydraulic supply to the differential cylinder under Interposition of a cooling device with a heat exchanger to take place taking into account the heated inlet plates occurring relatively high Temperatures ensure that the differential cylinders work properly to ensure.
  • FIG. 1 there is a continuous press 1 for Pressing pressed material mats 2 to pressed material plates in the train the production of chipboard, fiberboard and others Wood-based panels shown.
  • This press instructs Press lower part 3 and an upper press part 4, namely with endless in the lower press part 3 and upper press part 4 circumferential sheet steel press belts 5 and with a Inlet mouth E.
  • a heatable press plate 6, 7 is arranged, of which the upper press plate according to the embodiment 6 against the lower press plate 7 for setting the Press nip is adjustable.
  • On the press plates 6, 7 close heatable cantilever on the inlet side Inlet plates 8, 9 to form the inlet mouth E.
  • the steel sheet press belts 5 are on the press plates 6, 7 and Inlet plates 8, 9 with the interposition of rolling elements 10 or rolling rods supported. Furthermore, a device 11 for adjusting the inlet mouth E and a device 12 for setting the inlet contour of the inlet mouth E intended.
  • the device 12 for setting the Inlet contour has a plurality of double-acting Differential cylinders 13 on.
  • the differential cylinders 13 are in a predetermined distribution and according to Embodiment on the one hand to the upper inlet plate 8 and on the other hand articulated to the press upper part 4. Further are the differential cylinders 13 to a computer-controlled or regulated hydraulic system 14 connected. Of the Computer 15 and a measuring system 16, which the Mat thickness of the mats to be pressed 2 measures and forwarded to the computer 15 are only indicated.
  • the differential cylinders 13 are in longitudinal rows and Cross rows hinged to the upper inlet plate 8. At least this upper inlet plate 8 is drilled lengthways and consequently points in the longitudinal direction of the plate or in the direction of entry extending channels 18 for the heating medium. Due to the longitudinal channels 18 is the upper inlet plate for Absorption of much higher bending stresses than with transverse channels set up.
