Die Erfindung betrifft eine kontinuierliche Presse zum Verpressen von Preßgutmatten zu Preßgutplatten im Zuge der Herstellung von Spanplatten, Faserplatten und anderen Holzwerkstoffplatten, mit Pressenunterteil und Pressenoberteil, im Pressenunterteil und Pressenoberteil endlos umlaufenden Stahlpreßbändern, und mit einem Einlaufmaul,

  • wobei im Pressenunterteil und im Pressenoberteil jeweils eine beheizbare Preßplatte angeordnet ist und sich an die Preßplatten einlaufseitig vorkragende beheizbare Einlaufplatten unter Bildung des Einlaufmauls anschließen,
  • wobei die Stahlpreßbänder an den Preßplatten und Einlaufplatten unter Zwischenschaltung von Wälzkörpern abgestützt sind,
  • wobei ferner zur Einstellung der Einlaufkontur des Einlaufmauls eine Mehrzahl von Zylinderkolbenanordnungen vorgesehen ist, die in vorgegebener Verteilung einerseits an der oberen und/oder unteren Einlaufplatte, andererseits an dem Pressenoberteil und/oder Pressenunterteil angeschlossen sind.
    • 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 upper press part, in the lower part and upper part of the press, 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 heatable inlet plates protruding on the inlet side are connected to form the inlet mouth,
  • the steel press belts are supported on the press plates and inlet plates with the interposition of rolling elements,
  • a plurality of cylinder piston arrangements is also provided for adjusting the inlet contour of the inlet mouth, which are connected in a predetermined distribution on the one hand to the upper and / or lower inlet plate, and on the other hand to the upper press part and / or lower press part.

    • Es ist eine kontinuierliche Presse bekannt, bei welcher die obere der beiden beheizbaren Einlaufplatten unter Bildung von Gelenken in Plattenabschnitte unterteilt ist, so daß die Einlaufkontur des Einlaufmauls in den Gelenkbereichen Knickstellen aufweist. Das gilt auch für den Übergangsbereich zwischen der oberen Einlaufplatte und der sich anschließenden oberen Preßplatte. Bei dieser bekannten Ausführungsform wird mittels hydraulischer Stellglieder lediglich die Winkellage der Plattenabschnitte um die Drehachsen der Gelenke verstellt. Besonders problematisch ist die Tatsache, daß das zugeordnete Stahlpreßband beim Überfahren der Knickstellen entsprechende Abknickungen erfährt und folglich einem alsbaldigen Verschleiß unterliegt (vgl. DE 195 18 879).A continuous press is known in which the upper of the two heated inlet plates with formation of joints is divided into plate sections, so that the inlet contour of the inlet mouth in the joint areas Has kinks. This also applies to the transition area between the upper inlet plate and the adjoining one upper press plate. In this known embodiment is only by means of hydraulic actuators the angular position of the plate sections around the axes of rotation of the joints. The fact that that the assigned steel press belt when driving over the kinks experience corresponding kinks and consequently subject to wear and tear (see DE 195 18 879).

    Nach einem älteren nicht zum vorbekannten Stande der Technik gehörenden Recht ist zur Einstellung der Einlaufkontur des Einlaufmauls eine Mehrzahl von doppelt wirkenden Differentialzylindern vorgesehen, die in vorgegebener Verteilung einerseits an der oberen und/oder unteren Einlaufplatte, andererseits an dem Pressenoberteil und/oder Pressenunterteil angelenkt sind, wobei die Differentialzylinder an ein rechnergesteuertes oder -geregeltes Hydrauliksystem angeschlossen sind (vgl. DE 197 40 325). - Bei dieser älteren Ausführungsform sind die Differentialzylinder kardanisch an der oberen und/oder unteren Einlaufplatte und an dem Pressenoberteil und/oder Pressenunterteil angelenkt, wobei die Anlenkung der Differentialzylinder an der oberen und/oder unteren Einlaufplatte unter Zwischenschaltung von Wärmeisolierungen vorgenommen ist.According to an older not known to the Technology-related right is to adjust the inlet contour of the inlet mouth a plurality of double-acting Differential cylinders provided in a predetermined distribution on the one hand on the upper and / or lower inlet plate, on the other hand on the press top and / or Press lower part are articulated, the differential cylinder to a computer controlled or regulated one Hydraulic system are connected (see. DE 197 40 325). - In this older embodiment, the differential cylinders cardanic on the upper and / or lower inlet plate and on the upper press part and / or lower press part articulated, the articulation of the differential cylinder the upper and / or lower inlet plate with interposition of thermal insulation is made.

    Der Erfindung liegt die Aufgabe zugrunde, eine kontinuierliche Presse der eingangs beschriebenen Ausführungsform zu schaffen, bei welcher sich die Einlaufkontur des Einlaufmauls stufenlos unter Erzeugung beliebiger kontinuierlicher Biegelinien selbst bei Einsatz extrem biegsamer Einlaufplatten optimal einstellen läßt, so daß auch das Verpressen von extrem dünnen Preßgutmatten zu maßgerechten Preßgutplatten möglich ist.The invention has for its object a continuous Press to the embodiment described above create, in which the inlet contour of the inlet mouth steplessly generating any continuous Bending lines even when using extremely flexible inlet plates optimally adjusted, so that the pressing from extremely thin mats to customized sizes Pressed panels are possible.

    Diese Aufgabe löst die Erfindung bei einer gattungsgemäßen kontinuierlichen Presse dadurch, daß die Zylinderkolbenanordnungen zumindest an der oberen und/oder unteren Einlaufplatte unter Zwischenschaltung sphärischer Gelenklager und Isoliermittel angelenkt sind. - Im Rahmen der Erfindung kann es sich bei den Zylinderkolbenanordnungen um einfach wirkende oder doppelt wirkende Preßzylinder bzw. Differentialzylinder handeln. Während die Isoliermittel dazu dienen, im Wege einer Wärmedämmung funktionsstörende Deformationen im Bereich der sphärischen Gelenklager und auch der Zylinderkolbenanordnungen zu vermeiden, ermöglichen die sphärischen Gelenklager eine drehpunktartige Abstützung der Zylinderkolbenanordnungen dahingehend, daß sich beliebige und kontinuierliche Biegelinien in bezug auf die obere und/oder untere Einlaufplatte derart einstellen lassen, daß die Einlaufkontur in Anpassung an die jeweiligen betrieblichen Verhältnisse jeden erforderlichen Biegeradius annehmen kann und folglich ein vollvariabler Presseneinlauf zur Verfügung steht, um selbst extrem dünne Preßgutmatten von beipielsweise lediglich 3 mm maßgerecht und ohne Mattenabriß herstellen zu können. Das gilt auch unter Berücksichtigung einer Parallellage zwischen beiden Einlaufplatten. Hinzu kommt, daß sich aufgrund der sphärischen Gelenklager extrem biegsame Einlaufplatten einsetzen lassen, die als gleichsam Flexibelplatten funktionieren und dadurch im Wege einer Zug- und/oder Druckbeaufschlagung durch die Zylinderkolbenanordnungen stets einwandfrei in die jeweils gewünschte Form gebracht werden können. The invention solves this problem with a generic one continuous press in that the cylinder piston assemblies at least on the upper and / or lower inlet plate with the interposition of spherical spherical bearings and Insulating means are articulated. - Within the scope of the invention the cylinder piston arrangements can be simple acting or double-acting press cylinders or differential cylinders act. While the insulation means to do this serve, by way of thermal insulation malfunctioning deformations in the area of spherical spherical bearings and also to avoid the cylinder piston arrangements, allow the spherical spherical plain bearing a fulcrum-like support Cylinder piston arrangements in that any and continuous bend lines with respect to the upper one and / or let the lower inlet plate adjust so that the inlet contour in line with the respective operational Ratios assume every required bending radius can and therefore a fully variable press inlet is available to even extremely thin mats of, for example, only 3 mm true to size and without To be able to produce mat demolition. This also applies taking into account a parallel position between the two inlet plates. Add to that the fact that the spherical spherical bearings use extremely flexible inlet plates, that function as flexible plates, as it were, and as a result by means of a train and / or pressure by the Cylinder piston assemblies always perfectly in each desired shape can be brought.

    weitere erfindungswesentliche Merkmale sind im folgenden aufgeführt. So können die Zylinderkolbenanordnungen auch an dem Pressenoberteil und/oder Pressenunterteil oder an der Rahmenkonstruktion der Presse unter Zwischenschaltung von sphärischen Gelenklagern angelenkt sein. Die Gelenklager sind vorzugsweise als Kugelschalengelenke ausgebildet.

Bewegungsspiel verbunden, z. B. verschraubt sind. Auf diese Weise wird eine gleichsam kugelkalottenartige Abstützung der Zylinderkolbenanordnungen zwischen dem Pressenoberteil und der oberen Einlaufmatte und ggf. dem Pressenunterteil und der unteren Einlaufmatte erreicht. Die Kugelköpfe können einen die Lageröffnung in den Kugelschalen zumindest teilweise mit vorgegebenem Lagerspiel durchdringenden Verbindungsschaft für die Verschraubung der Zylinder oder Kolben der betreffenden Zylinderkolbenanordnungen aufweisen, wobei also dieser Verbindungsschaft selbst zur Aufnahme einer Verbindungsschraube geeignet ist. Zur Verwirklichung einer einwandfreien Isolierung sind die Kugelschalen vorzugsweise unter schalenrandseitiger Zwischenschaltung von Isolierringen mit der oberen und/oder unteren Einlaufplatte verbunden.Further features essential to the invention are as follows listed.
