Description
Die Erfindung betrifft eine Presse, insbesondere kontinuierliche Presse zum Verpressen von Preßgutmatten zu Preßgutplatten im Zuge der Herstellung von Spanplatten, Faserplatten und anderen Holzwerkstoffplatten, mit Pressenoberteil und Pressenunterteil über die Pressenlänge in vorgegebenen Abständen verbindender. Pressenrahmen und mit innerhalb der Pressenrahmen angeordneten oberen und unteren Preßplatten, wobei auf die oberen und/oder unteren Preßplatten Preßzylinderkolbenanordnungen arbeiten und im Bereich der Pressenrahmen jeweils eine Mehrzahl von Preßzylinderkolbenanordnungen in Reihe angeordnet und einerseits an den oberen und/oder unteren Querholm der betreffenden Pressenrahmen, andererseits an die obere und/oder untere Preßplatte angeschlossen ist.The invention relates to a press, in particular continuous press for pressing pressed material mats Pressed board in the course of the production of chipboard, Fiberboard and other wood-based panels, with Upper press part and lower press part over the press length connecting at predetermined intervals. Press frame and with upper and inside the press frames lower press plates, being on the upper and / or lower Press plates ram cylinder piston assemblies work and in Range of press frames each a plurality of Press cylinder piston assemblies arranged in series and on the one hand on the upper and / or lower cross member of the press frame concerned, on the other hand to the upper and / or lower press plate is connected.
Es sind derartige kontinuierlich arbeitende Pressen bekannt, bei denen im Pressenoberteil und Pressenunterteil endlos umlaufende Stahlpreßbänder unter Zwischenschaltung von Rollstäben an den Preßplatten abgestützt und die Preßzylinderkolbenanordnungen als einzelne Baueinheiten ausgebildet sind. Folglich muß eine singuläre Montage und Versorgung der einzelnen Preßzylinderkolbenanordnungen mit einem Hydraulikmedium erfolgen. Die singuläre Montage ist problematisch, weil sich die Einzelzylinder der in Pressenrahmen in Reihe angeordneten Preßzylinderkolbenanordnungen in Relation zueinander verschieben können. Derartige Zylinderverschiebungen resultieren aus Verformungen der Pressenrahmen bzw. ihrer Querholme im Zuge des Preßvorganges, zumal die Zylindermontage regelmäßig auf den Querholmen der Pressenrahmen erfolgt. Aus den Verschiebungen der Einzelzylinder resultieren erhöhte Verschleißerscheinungen und Dichtungsprobleme, insbesondere aber auch ungleichmäßige Druckverteilungen auf die Pressplatten. Das wiederum kann zu Qualitätsminderungen bei den gepressten Produkten wie beispielsweise Spanplatten, Faserplatten oder dergleichen Holzwerkstoffplatten führen. Die singuläre Versorgung ist problematisch, weil zu jeder einzelnen Presszylinderkolbenanordnung die für deren Betätigung mittels eines Hydraulikmediums erforderlichen Versorgungsleitungen verlegt werden müssen. Das führt zu einer raumaufwendigen Bauweise, obwohl nur wenig Montageplatz zur Verfügung steht und deshalb stets eine enge und kompakte Bauweise angestrebt wird. Hinzukommt, dass die Montage der versorgungsleitungen selbst aufwendig und schwierig ist. Ferner muss eine ungeschützte Verlegung der Versorgungsleitungen in Kauf genommen werden. Im übrigen ist auch die Zylinderhalterung der einzelnen Presszylinderkolbenanordnungen verhältnismäßig kompliziert. Im Übrigen kennt man eine Presse, bei welcher das Pressenunterteil von einer Mehrzahl sockelartiger Zylinderblöcke gebildet wird, in welche Presszylinderkolbenanordnungen in mehreren Reihen angeordnet sind (vgl. FR 911 076 A). Bei dieser bekannten Ausführungsform sind zwar die Versorgungsleitungen für die Presszylinderkolbenanordnungen in die Zylinderblöcke integriert, jedoch sind derartige Zylinderblöcke zur Bildung des Pressenunterteils in fertigungs- und montagetechnischer Hinsicht aufwendig. unterteils in fertigungs- und montagetechnischer Hinsicht aufwendig.These are continuously operating presses known, in which in the upper press part and lower press part endless steel press belts with interposition supported by roller bars on the press plates and the Press cylinder piston assemblies as individual units are trained. Consequently, a singular montage and Supply of the individual cylinder press assemblies with a hydraulic medium. The singular montage is problematic because the individual cylinders of the in Press frame arranged in row press cylinder piston assemblies shift in relation to each other can. Such cylinder displacements result from Deformation of the press frame or its cross bars in the course the pressing process, especially since the cylinder assembly on regularly the cross bars of the press frame. From the Displacements of the individual cylinders result in increased Signs of wear and sealing problems, in particular but also uneven pressure distributions on the Press plates. This, in turn, can reduce quality the pressed products such as chipboard, Guide fiberboard or similar wood-based panels. The singular care is problematic because of everyone individual press cylinder piston assembly for their Actuation required using a hydraulic medium Supply lines must be laid. That leads to a space-consuming construction, although only a little Assembly space is available and therefore always one narrow and compact design is sought. Come in addition, that the installation of the supply lines itself is complex and is difficult. Furthermore, an unprotected installation of the supply lines are accepted. in the the other is also the cylinder holder of the individual Press cylinder piston arrangements are relatively complicated. Incidentally, you know a press where this Press base of a plurality of base-like Cylinder blocks is formed, in which cylinder press assemblies are arranged in several rows (cf. FR 911 076 A). In this known embodiment the supply lines for the press cylinder piston assemblies integrated into the cylinder blocks, however are such cylinder blocks to form the lower press part from a manufacturing and assembly point of view consuming. partly in terms of manufacturing and assembly technology consuming.
Der Erfindung liegt die Aufgabe zugrunde, eine Presse, insbesondere kontinuierliche Presse, der eingangs beschriebenen Ausführungsform zu schaffen, die sich durch eine einfache, funktionsgerechte und betriebssichere Montage der Presszylinderkolbenanordnungen auszeichnet.The invention has for its object a press, in particular continuous press, the one described above To create embodiment, which is characterized by a simple, functional and reliable installation of the Press cylinder piston arrangements distinguished.
Diese Aufgabe löst die Erfindung bei einer gattungsgemäßen Presse, insbesondere kontinuierlichen Presse, der eingangs beschriebenen Ausführungsform dadurch, dass die Zylinder der jeweils in Reihe angeordneten Presszylinderkolbenanordnungen in einem gemeinsamen Zylinderblock angeordnet sind, und dass die Versorgungsleitungen, z. B. Hydraulikleitungen für die Preßzylinderkolbenanordnungen in den Zylinderblock integriert sind. - Diese Maßnahmen der Erfindung haben zur Folge, daß die Zylinder einer Preßzylinderreihe einschließlich ihrer Versorgungsleitungen en bloc erfolgen kann. Dadurch wird die Montage sowohl der Zylinder als auch ihrer Versorgungsleitungen erheblich erleichtert und auf engstem Raum möglich. Da die Zylinder in einem Zylinderblock zusammengefaßt sind, sind gegenseitige Verschiebungen der Zylinder praktisch ausgeschlossen, vielmehr wird stets eine gleichmäßige Druckverteilung im Zuge des Preßvorganges erreicht, zumal die Orte des Kraftangriffes stets die gleichen sind. Hinzukommt, daß Verformungen der betreffenden Querholme der Pressenrahmen beachtlich reduziert werden, wenn der Zylinderblock auf solchen Querholmen montiert wird und zu deren Versteifung beiträgt. Berücksichtigt man ferner die Tatsache, daß die Versorgungsleitungen für die Zylinder in dem Zylinderblock untergebracht sind, dann resultiert daraus eine geschützte und insgesamt besonders betriebssichere und funktionsgerechte Bauweise, die sich durch einfache Montage auszeichnet und zu einer Stabilisierung der Pressenrahmen infolge der Blocksteifigkeit des Zylinderblocks führt.The invention solves this problem with a generic one Press, especially continuous press, of the beginning described embodiment in that the cylinder of the press cylinder piston arrangements arranged in series arranged in a common cylinder block are and that the supply lines, e.g. B. hydraulic lines for the Press cylinder piston assemblies in the cylinder block are integrated. - These measures of the invention have Consequence that the cylinders of a row of press cylinders including their supply lines are carried out en bloc can. This will assemble both the cylinder as well of their supply lines considerably easier and on confined space possible. Because the cylinders are in a cylinder block summarized are mutual shifts the cylinder is practically excluded, rather always an even pressure distribution in the course of the pressing process reached, especially since the places of the force attack always the are the same. In addition, deformations of the relevant cross bars of the press frame considerably be reduced if the cylinder block on such Crossbars is mounted and contributes to their stiffening. If one also takes into account the fact that the Supply lines for the cylinders in the cylinder block are then protected and overall particularly reliable and Functional design, which is easy to assemble distinguished and to stabilize the press frame due to the block rigidity of the cylinder block.
Die Erfindungslehre läßt sich auch bei einer Taktpresse verwirklichen, bei welcher dann der Zylinderblock gegen das Pressenoberteil oder Pressenunterteil oder gegen die obere oder untere Preßplatte abgestützt ist, und die Kolben der betreffenden Preßzylinderkolbenanordnungen an die obere oder untere Preßplatte oder an das Pressenoberteil oder das Pressenunterteil angeschlossen sind. Auch bei einer Taktpresse wird auf diese Weise eine gute Druckverteilung erzielt.The theory of the invention can also be used in a cycle press realize in which then the cylinder block against the Upper press part or lower press part or against the upper one or lower press plate is supported, and the piston relevant cylinder press assemblies to the upper or lower press plate or to the press top or that Lower press part are connected. Even with one In this way, cycle press becomes a good pressure distribution achieved.
Weitere erfindungswesentliche Merkmale sind im folgenden aufgeführt. So sieht die Erfindung vor, daß der Zylinderblock gegen den oberen oder unteren Querholm der betreffenden Pressenrahmen oder gegen die obere oder untere Preßplatte abgestützt ist, und daß die Kolben der betreffenden Preßzylinderkolbenanordnungen an der oberen oder unteren Preßplatte oder an dem oberen oder unteren Querholm der Pressenrahmen angeschlossen sind. Vorzugsweise wird man den Zylinderblock an einen Querholm der Pressenrahmen abstützen, während der Anschluß der Kolben bzw. ihrer Kolbenstangen an eine Preßplatte ein hinreichendes Bewegungsspiel zum Ausgleich von Verformungen sowohl der Pressenrahmen als auch der Preßplatten im Zuge eines Preßvorganges zuläßt. Der Zylinderblock ist erfindungsgemäß als Gußblock, z. B. aus Grauguß oder Stahlguß, mit einer eingegossenen Verrohrung zur Bildung der Versorgungsleitungen ausgebildet. Es besteht aber auch die Möglichkeit, daß die Versorgungsleitungen als Bohrungen in dem Zylinderblock ausgeführt sind, der auch als Stahlblock ausgeführt sein kann. Auf diese Weise sind Dichtungsprobleme insbesondere zwischen den Versorgungsleitungen und den Zylindern nicht länger zu befürchten. Die Zylinder sind zweckmäßigerweise von außen nach innen paarweise, jedenfalls unter Verwirklichung einer symmetrischen Druckbeaufschlagung an die Versorgungsleitungen angeschlossen. Bei einem in der Gußblockmitte angeordneten Zylinder sind für diesen Zylinder eigene Versorgungsleitungen für das Hydraulikmedium vorgesehen. Nach einer bevorzugten Ausführungsform sind sämtliche Zylinder eines Zylinderblocks an die gleichen Versorgungsleitungen angeschlossen. - Jedenfalls lassen sich bei dem erfindungsgemäßen Zylinderblock die Zylinder derart mit dem Hydraulikmedium versorgen, daß eine gleichmäßige Druckverteilung und -übertragung auf die Preßplatten gewährleistet ist.Further features essential to the invention are as follows listed. So the invention provides that the Cylinder block against the upper or lower cross member of the press frame in question or against the upper or lower Press plate is supported, and that the piston of relevant cylinder press assemblies on the upper or lower press plate or on the upper or lower Crossbar of the press frame are connected. Preferably the cylinder block is attached to a crossbar Support the press frame while connecting the pistons or their piston rods on a press plate sufficient movement to compensate for deformation both the press frame and the press plates in the train of a pressing process. The cylinder block is according to the invention as a casting block, for. B. from gray cast iron or Cast steel, with cast piping for formation of the supply lines. But there is also the possibility that the supply lines as holes are executed in the cylinder block, also as Steel block can be executed. That way Sealing problems especially between the Supply lines and the cylinders are no longer closed fear. The cylinders are expediently from the outside inside in pairs, at least with the realization of one symmetrical pressurization to the supply lines connected. One in the middle of the casting block arranged cylinders are separate for this cylinder Supply lines for the hydraulic medium are provided. According to a preferred embodiment, all are Cylinder of a cylinder block to the same Supply lines connected. - Leave it anyway the cylinders in the cylinder block according to the invention so supply with the hydraulic medium that a even pressure distribution and transfer to the Press plates is guaranteed.
