Description

Die Erfindung betrifft eine Plattenpresse zum Herstellen von Mehrschichtenplatten, insbesondere beschichteten Hartschaumkunststoffplatten, - mit einer ortsfesten unteren Pressenplatte und einer in zumindest einem Portalrahmen auf- und niederbewegbar gelagerten oberen Pressenplatte, wobei die untere Pressenplatte mit einer Preßgut-Längstransporteinrichtung versehen ist und die obere Pressenplatte über Hydraulikzylinderkolbenanordnungen an den bzw. die Portalrahmen angeschlossen ist.The invention relates to a plate press for producing multilayer plates, in particular coated rigid foam plastic plates, with a stationary lower press plate and an upper press plate mounted in at least one gantry frame, the lower press plate being provided with a longitudinal material transport device and the upper press plate above Hydraulic cylinder piston assemblies is connected to the portal frame (s).

Plattenpressen dieser Art werden hauptsächlich im Zuge der Beschichtung von Hartschaumkunststoffplatten mit Sperrholzplatten und/oder Kaschierfolien eingesetzt, wobei die unter Zwischenschaltung von Bindemittelschichten geschichteten Platten - gegebenenfalls auch mehrfach in Stapeln - bis zum Erhärten des Bindemittels in der Plattenpresse gepreßt werden.Plate presses of this type are mainly used in the course of coating hard foam plastic sheets with plywood sheets and / or laminating foils, with the sheets layered with the interposition of binder layers - optionally several times in stacks - are pressed in the plate press until the binder has hardened.

Eine bekannte Plattenpresse der eingangs genannten Art (EP-A 90 959) wird vornehmlich zum Beschichten von Formkörpern, insbesondere aus Weichschaumkunststoff, eingesetzt. Die Pressenplatten sind offensichtlich wie üblich aus Stahl hergestellt. Als Preßgut-Längstransporteinrichtung dient eine Unterdeckschicht, mit der der Formkörper in die Plattenpresse eingezogen und aus dieser wieder herausgezogen wird. Nachteilig ist insoweit, daß nach dem Pressen in jedem Fall eine Besäumung erforderlich ist. Nachteilig ist aber auch der hohe technische Aufwand für die Pressenplatten.A known plate press of the type mentioned at the outset (EP-A 90 959) is used primarily for coating moldings, in particular made of flexible foam plastic. The press plates are obviously made of steel as usual. A bottom cover layer is used as the longitudinal material to be pressed, with which the molded body is drawn into the plate press and pulled out of it again. It is disadvantageous in this respect that trimming is required in any case after the pressing. However, the high technical outlay for the press plates is also disadvantageous.

Bekannt ist auch eine Furnierpresse mit ortsfester unterer Pressenplatte und oberem Preßkissen (CH-B 203 501), bei der die untere Pressenplatte mit I-Stahlträgern und einer darauf befestigten Platte ausgeführt ist. Als Preßgut-Längstransporteinrichtung dient eine längsverschiebbare Boden- bzw. Unterlagsplatte. Die I-Stahlträger verlaufen quer zur Pressenlängsrichtung und die auf der Oberseite der Träger befestigte Platte bildet nicht die untere Preßfläche. Die Funktion wird vielmehr von der Oberseite der ausziehbaren Bodenplatte wahrgenommen.Also known is a veneer press with a fixed lower press plate and upper press cushion (CH-B 203 501), in which the lower press plate is made with I-steel girders and a plate attached to it. A longitudinally displaceable base or base plate serves as the longitudinal material to be pressed. The I-steel beams run transversely to the longitudinal direction of the press and the plate attached to the top of the beams does not form the lower pressing surface. The function is rather perceived from the top of the extendable base plate.

Der Erfindung liegt die Aufgabe zugrunde, eine Plattenpresse der eingangs genannten Art so weiter zu entwickeln, daß sie erheblich kostengünstiger herstellbar ist und einen Preßgut-Längstransport aufweist, der eine Besäumung der Mehrschichtenplatte nach dem Pressen nicht erzwingt.The invention has for its object to develop a plate press of the type mentioned so that it is much cheaper to manufacture and has a material to be transported longitudinally, which does not force a trimming of the multilayer plate after pressing.

Die erfindungsgemäße Lösung dieser Aufgabe besteht darin, daß die untere und die obere Pressenplatte jeweils als Betonplatte mit Armierung aus Baustahlgewebematten sowie daran angeschlossenen I-Stahllängsträgern ausgebildet sind, daß auf den mit ihrem Oberteil aus der Betonplatte vorstehenden und Längskammern bildenden I-Stahllängsträgern der unteren Pressenplatte mit Blasluftdurchtritten versehene, mit ihrer Oberseite die untere Preßfläche bildende Sperrholzplatten befestigt sind und zwischen benachbarten Sperrholzplatten Längstransportketten angeordnet sind, deren Obertrum mit Hilfe von Huborganen über die untere Preßfläche hervorhebbar ist, und daß die Hydraulikzylinderkolbenanordnungen an die I-Stahllängsträger der oberen Pressenplatte angeschlossen sind.The solution to this problem according to the invention is that the lower and the upper press plate are each designed as a concrete plate with reinforcement made of structural steel mesh and I-steel longitudinal members connected to it, that on the upper part of the concrete plate projecting and longitudinal chambers forming I-steel longitudinal members of the lower press plate plywood panels provided with blown air passages, with their upper side forming the lower press surface, are attached and longitudinal transport chains are arranged between adjacent plywood panels, the upper run of which can be lifted over the lower press surface with the aid of lifting elements, and that the hydraulic cylinder piston assemblies are connected to the I-steel longitudinal members of the upper press plate.

Die Erfindung nutzt hierbei zunächst die Erkenntnis, daß insbesondere bei großdimensionierten Plattenpressen der genannten Art ohne weiteres auch mit billigen Betonplatten als Pressenplatten gearbeitet werden kann, wenn diese entsprechende Armierungen aufweisen. Über diese Armierungen wird insbesondere die obere Pressenplatte besonders gut manipulierbar. Außerdem nutzt die Erfindung die Erkenntnis, daß bei ortsfester unterer Pressenplatte der konstruktive Aufwand für die Längstransporteinrichtung wesentlich vereinfacht werden kann. Verwiesen wird hierzu auf die besagten Blasluftzutritte einerseits, die Längstransportketten andererseits, die von selbst optimale konstruktive Verhältnisse ergeben. Bei der erfindungsgemäßen Plattenpresse bestehen also die Pressenplatten aus armierten Betonplatten, während die Preßgut-Längstransporteinrichtung gleichsam als Luftkissenerzeugungsgerät ausgebildet ist. Die Betonplatten können ohne weiteres am Aufstellungsort der Plattenpresse mit planparallelen Preßflächen hergestellt werden. Bezüglich des Längstransportes des Preßgutes bestehen keine Probleme, weil das Luftkissen eine extrem schonende Behandlung des Preßgutes erlaubt. Alles das wird mit besonders niedrigen Gestehungskosten ermöglicht; mit einer erfindungsgemäßen Plattenpresse ist eine Reduzierung der Gestehungskosten auf etwa 20% der Kosten einer bekannten Plattenpresse mit Stahlpressenplatten möglich.The invention first uses the knowledge that, in particular in the case of large-sized plate presses of the type mentioned, it is also readily possible to work with cheap concrete plates as press plates if they have appropriate reinforcements. The upper press plate in particular can be manipulated particularly well via these reinforcements. In addition, the invention uses the knowledge that the design effort for the longitudinal transport device can be significantly simplified with a fixed lower press plate. Reference is made to the said blown air intakes on the one hand, and the longitudinal transport chains on the other hand, which automatically result in optimal structural conditions. In the plate press according to the invention, the press plates thus consist of reinforced concrete plates, while the material to be pressed longitudinally is designed, as it were, as an air cushion generating device. The concrete slabs can easily be produced at the installation site of the plate press with plane-parallel pressing surfaces. With regard to the longitudinal transport of the material to be pressed there are no problems, because the air cushion permits extremely gentle treatment of the material to be pressed. All of this is made possible with particularly low production costs; With a plate press according to the invention, it is possible to reduce the production costs to approximately 20% of the costs of a known plate press with steel press plates.

Für die weitere Ausgestaltung bestehen im Rahmen der Erfindung mehrere Möglichkeiten. So bestehen nach einer bevorzugten Ausführungsform die Pressenplatten aus einem Beton B 17, 5 der Klasse I, Konsistenzgebiet 3 nach NEN 3861 (Nederlands Normalisatie-Instituut / April 1974). Die I-Stahllängsträger sind zweckmäßigerweise mit den Baustahlgewebematten verschweißt. Wie oben schon einmal angedeutet worden ist, kann bei der erfindungsgemäßen Plattenpresse auf besonders einfache Weise Planparallelität der Pressenplatten erreicht werden. Hierzu ist nach einer bevorzugten Ausführungsform die Anordnung so getroffen, daß die Preßfläche der oberen Pressenplatten als Komplementärfläche zur unteren Preßfläche ausgebildet ist. Die untere Pressenplatte, deren Sperrholzplatte die untere Preßfläche bildet, kann ohne große Probleme auf Ebenheit gearbeitet werden. Legt man dann auf die Sperrholzplatte eine Trennfolie, so erreicht man die Planparallelität der oberen Pressenplatte einfach dadurch, daß man die obere Pressenplatte durch Betonguß auf eben dieser Trennfolie erzeugt. Im übrigen empfiehlt es sich, die obere Pressenplatte über je zwei Hydraulikzylinderkolbenanordnungen am zugeordneten Portalrahmen zu befestigen. Im übrigen hat sich eine Ausführungsform bewährt, bei der die Blasluftdurchtritte jeweils aus einer Stufenbohrung bestehen, in der eine Kugel, insbesondere Stahlkugel, mit einem oberen Einsatzring, z.B. aus Kunststoff, gehalten ist. Schließlich und endlich empfiehlt es sich, als Huborgane Luftkissen einzusetzen.There are several possibilities for the further configuration within the scope of the invention. According to a preferred embodiment, the press plates consist of a concrete B 17, 5 of class I, consistency area 3 according to NEN 3861 (Nederlands Normalisatie-Instituut / April 1974). The I-steel longitudinal beams are expediently welded to the structural steel mesh mats. As has already been indicated above, plane parallelism of the press plates can be achieved in a particularly simple manner in the plate press according to the invention. For this purpose, according to a preferred embodiment, the arrangement is such that the pressing surface of the upper press plates is designed as a complementary surface to the lower pressing surface. The lower press plate, whose plywood plate forms the lower press surface, can be worked on flatness without great problems. If you then place a separating film on the plywood plate, the plane parallelism of the upper press plate can be achieved simply by producing the upper press plate by concrete casting on this separating film. For the rest, it is advisable to attach the upper press plate to the associated portal frame using two hydraulic cylinder piston assemblies. For the rest, an embodiment has proven itself in which the blown air passages each consist of a stepped bore in which a ball, in particular a steel ball, with an upper insert ring, e.g. made of plastic. Finally, it is advisable to use air cushions as lifting devices.

Im folgenden wird die Erfindung anhand einer ein Ausführungsbeispiel darstellenden Zeichnung näher erläutert; es zeigen:

  • Fig. 2 einen Querschnitt durch den Gegenstand der Fig. 1,
  • Fig. 3 das Detail A aus Fig. 2 in vergrößerter Darstellung, und
  • Fig. 4 das Detail B aus Fig. 2 in vergrößerter Darstellung.
The invention is explained in more detail below with reference to a drawing which represents an exemplary embodiment; show it:
  • 1 shows a longitudinal section through a plate press,
  • 2 shows a cross section through the subject of FIG. 1,
  • Fig. 3 shows the detail A of Fig. 2 in an enlarged view, and
  • Fig. 4 shows the detail B of FIG. 2 in an enlarged view.

Die in den Figuren dargestellte Plattenpresse dient zum Herstellen von Mehrschichtenplatten, insbesondere beschichteten Hartschaumkunststoffplatten und besteht in ihrem grundsätzlichen Aufbau aus einer unteren Pressenplatte 1 und einer oberen Pressenplatte 2, die in zwei Portalrahmen 3 angeordnet ist. Die eine Pressenplatte 1 ist ortsfest, die andere Pressenplatte 2 auf- und niederbewegbar gelagert. Ausweislich Fig. 3 ist die untere Pressenplatte mit einer Preßgut-Längstransporteinrichtung 4 versehen.The plate press shown in the figures is used to manufacture multi-layer plates, in particular coated rigid foam plastic plates, and its basic structure consists of a lower press plate 1 and an upper press plate 2, which is arranged in two portal frames 3. One press plate 1 is stationary, the other press plate 2 is mounted to move up and down. As shown in Fig. 3, the lower press plate is provided with a material to be transported longitudinally 4.

Die untere und die obere Pressenplatte 1, 2 sind jeweils als Betonplatte mit Armierung aus Baustahlgewebematten 5 sowie daran angeschweißten I-Stahllängsträgern 6 ausgeführt. Dabei ist auf den mit ihrem Oberteil aus der Betonplatte vorstehenden und Längskammern 7 bildenden I-Stahllängsträgern 6 der ortsfesten unteren Pressenplatten 1 eine mit Blasluftdurchtritten 8 versehene, mit ihrer Oberseite die untere Preßfläche 9 bildende Sperrholzplatte 10 befestigt. Die I-Stahllängsträger 6 der beweglichen oberen Pressenplatte 2, die über zusätzliche I-Stahlquerträger 11 in der oberen Pressenplatte 2 ergänzt sein können, sind über je zwei Hydraulikzylinderkolbenanordnungen 12 an die Portalrahmen 3 angeschlossen. Die Pressenplatten 1, 2 bestehen im einzelnen aus einem Beton B 17, 5 der Klasse 1, Konsistenzgebiet 3 nach NEN 3861. Wie man ohne weiteres erkennt, ist die Preßfläche der oberen Pressenplatte 2 als Komplementärfläche zur unteren Preßfläche 9 ausgebildet, was in der oben schon einmal beschriebenen Art und Weise erreicht worden ist. Insbesondere aus Fig. 3 erkennt man im einzelnen, daß die Blasluftdurchtritte 8 jeweils aus einer Stufenbohrung 13 bestehen, in der eine Kugel 14 aus Stahl von einem oberen Einsatzring 15 auf Kunststoff gehalten ist. Es versteht sich von selbst, daß die Längskammern 7 an eine Druckluftquelle angeschlossen sind. Im übrigen entnimmt man Fig. 4, daß die untere Pressenplatte 1 mit zwischen benachbarten Sperrholzplatten 10 angeordneten Längstransportketten 15 versehen ist, deren Obertrum mit Hilfe eines Luftkissens über die untere Preßfläche 9 hervorhebbar ist.The lower and the upper press plate 1, 2 are each designed as a concrete plate with reinforcement made of reinforcing steel mesh 5 and I-steel longitudinal members 6 welded to it. In this case, on the upper part protruding from the concrete slab and forming longitudinal chambers 7, I-steel longitudinal members 6 of the stationary lower press plates 1, a plywood plate 10 provided with blown air passages 8 and with its upper side forming the lower pressing surface 9 is fastened. The I-steel longitudinal members 6 of the movable upper press plate 2, which can be supplemented by additional I-steel cross members 11 in the upper press plate 2, are each connected to the portal frame 3 via two hydraulic cylinder piston assemblies 12. The press plates 1, 2 consist in particular of a concrete B 17, 5 of class 1, consistency area 3 according to NEN 3861. As can easily be seen, the press surface of the upper press plate 2 is designed as a complementary surface to the lower press surface 9, which in the above previously described manner has been achieved. From Fig. 3 in particular it can be seen in detail that the blown air passages 8 each consist of a stepped bore 13 in which a ball 14 made of steel is held by an upper insert ring 15 on plastic. It goes without saying that the longitudinal chambers 7 are connected to a compressed air source. 4 that the lower press plate 1 is provided with longitudinal transport chains 15 arranged between adjacent plywood plates 10, the upper run of which can be highlighted by means of an air cushion over the lower pressing surface 9.

Auf der anderen Seite entnimmt man den Fig. 1 und 2, daß die Plattenpresse gleichsam durch weitere Pressenplatten ergänzt sein kann, wobei die unteren Pressenplatten 1 zu einer einzigen unteren Pressenplatte vereinigt sind. Entsprechend können auch die Portalrahmen 3 benachbarter Plattenpressen ineinander integriert sein.On the other hand, it can be seen from FIGS. 1 and 2 that the plate press can be supplemented, as it were, by further press plates, the lower press plates 1 being combined into a single lower press plate. Correspondingly, the portal frames 3 of adjacent plate presses can also be integrated into one another.
