Die Erfindung betrifft eine Vorrichtung zur kontinuierlichen Herstellung von Verbundelementen mit profilierten Deckschichten und einer Kernschicht aus Kunstharzschaum, bestehend aus im wesentlichen einer Abwickelstation, einer mit Walzen bestückten Profiliereinrichtung, einer Schäumvorrichtung, einer Förderund Halteeinrichtung und einer Trennvorrichtung.The invention relates to a device for the continuous production of composite elements with profiled cover layers and a core layer made of synthetic resin foam, consisting essentially of one Unwinding station, a profiling device equipped with rollers, a foaming device, a conveyor and Holding device and a separating device.
Derartige Einrichtungen sind z. B. aus den DT-OS 09 668 und 17 79 192 bekannt, wobei ebene Sandwichplatten aus metallischen Deckschichten und einer Kernschicht aus Polyurethan-Hartschaum hergestellt werden, und die Längsränder eine rinnenförmige, das Herausfließen des Schaumes verhindernde Verbindungsprofilierung und die Oberflächen eine schwache Längsprofilierung vor dem Ausschäumen in einer Walzprofiliermaschine erhalten.Such facilities are z. B. from the DT-OS 09 668 and 17 79 192 known, with flat sandwich panels made of metallic cover layers and a Core layer made of rigid polyurethane foam, and the longitudinal edges a channel-shaped, the Connection profiling preventing the foam from flowing out and the surfaces a weak one Longitudinal profile obtained before foaming in a roll forming machine.
Das Formhalten und Fördern derartiger, ebener oder quasiebener Sandwichstränge während der Erhärtung des Kunststoffschaumes geschieht üblicherweise durch ein DoDDelDlattenband.Maintaining the shape and conveying such flat or quasi-flat sandwich strands during the hardening process The plastic foam is usually done using a DoDDel slat band.
Im Gegensatz zu derartigen, im wesentlichen ebenen Sandwichplatten, die wegen der Kriechneigung des Schaumes bei Langzeitbeaiispruchungen als tragende Bauteile nicht geeignet sind, können - wie Versuche bewiesen haben - trapezförmige Sandwich-Faltwerke, die sich aus um jeweils 180° versetzten Einzeltrögep. zusammensetzen, deren gesamte Bauhöhe ein Vielfaches der Wanddicke ist, als Tragwerke großer «pannweite ohne Beeinträchtigung des Tragverhaltens unter Langzeitbeanspruchung eingesetzt werden. In contrast to such, essentially flat sandwich panels, which are unsuitable as load-bearing components due to the foam's tendency to creep in the event of long-term stresses, - as tests have shown - trapezoidal sandwich panels, which are made up of individual troughs offset by 180 °. assemble, the overall height of which is a multiple of the wall thickness, can be used as supporting structures with a large span without impairing the load-bearing behavior under long-term stress.
Da bei derartigen Faltwerken sowohl die Formgebung der Deckschichten als auch die Formhaltung des erhärtenden Verbundelementes wegen der großen Bauhöhe des Einzeltroges besondere Schwierigkeiten bereitet, wurden derartige Einzehröge bisher unwirtschaftlich und mit verhältnismäßig großem Aufwand diskontinuierlich in Einzelformen hergestellt. Since in such folded plates, both the shape of the outer layers is preparing as well as the shape retention of the hardening composite element because of the great height of the individual trough special difficulties, such Einzehröge were made previously uneconomical and relatively great expense discontinuously in individual molds.
Bei einer halbkontinuierlichen Fertigung ebener Verbundelemente aus vorgefertigten, einzelnen Deck schichten sind an sich aus der DT-OS 17 04 951 in und aus Arbeitsstellung bewegbare Begrenzungsrollen bekannt, die Außen- und Basisschicht bis zum Ende des Aufschäumprozesses in genauem Abstand halten.In the case of a semi-continuous production of flat composite elements from prefabricated, individual decks layers are from DT-OS 17 04 951 in and Known from the working position movable delimitation rollers, the outer and base layer until the end of the Keep the foaming process at a precise distance.
Der Erfindung liegt die Aufgabe zugrunde, cmc Vorrichtung zu schaffen, mit der in einfacher Weise emc koitinuierliche Herstellung trogförmiger Sanduichfah-ν-erke erfolgen kann.The invention is based on the object of cmc To create a device with which emc co-continuous production of trough-shaped sanduichfah-ν-erke can be done.
Gemäß der Erfindung wird dazu bei einer Vorrichtung der eingangs näher bezeichneten Gattung vorgeschlagen, daß der Profiliereinrichtung eine Anbiegeeinheit mit mehreren Walzenstufen aus jeweils zwei angetriebenen Anbiegewalzen und eine Aufstellemheii nachgeschaltet sind, die Aufstellwalzenpaare und Führungswahenpaare aufweist, und daß die Förderund Halteeinrichtung aus den Gurt fassenden Formhaitewalzenpaaren und die beiden Schenkel des Verbund elementstranges fassenden Formhaltewalzenpaaren gebildet ist.According to the invention, this is done in a device of the type specified in the introduction proposed that the profiling device be a bending unit with several roller stages each consisting of two driven bending rollers and a set-up unit are connected downstream, which has pairs of positioning rollers and pairs of guides, and that the conveyor and Holding device from the belt-gripping form holding roller pairs and the two legs of the composite Element strand gripping form holding roller pairs is formed.
Durch die erfindungsgemäße Vorrichtung werden in vorteilhafter Weise die im vorliegenden Fall durch die Profilform bedingten besonderen Probleme gelöst und die kontinuierliche Herstellung von trogförmigen Sandwichfaltwerken ermöglicht, wcbei sich dabei als zweckmäßig erwiesen hat, daß das Anbiegen bis zu einem Winkel von etwa 10° und das Aufstellen bis zu einem Winkel von etwa 55' erfolgt.By the device according to the invention are in an advantageous manner in the present case by Profile shape-related special problems solved and the continuous production of trough-shaped Allows sandwich folding works, which has proven to be useful, that the bending up to at an angle of about 10 ° and the installation is carried out up to an angle of about 55 '.
Die Formgebung in der Anbiegeeinheit durch die angetriebenen Anbiegewalzen versteift dabei die beiden Deckschichten vorteilhaft so weitgehend, daß sie durch die nicht angetriebene Aufstelleinheit gedrückt werden können, in der gerräß einem anderen Merkmal der Erfindung jeweils zwei, den Stegen der Deckschichten zugeordnete Aufstellwalzenpaare in Fertigungsrichtung in einer von Stufe zu Stufe zunehmende Winkellage angeordnet sind.The shaping in the pre-bending unit by the driven pre-bending rollers stiffens the two Cover layers advantageously so largely that they are pressed by the non-driven erection unit can, in the gerräß another feature of the invention, two each, the webs of the cover layers Associated pairs of erecting rollers in the direction of production in an angular position increasing from step to step are arranged.
Um die gesamte Oberfläche des Verbundelementstranges bestreichen zu können, können vorteilhaft die Aufstell- und Führungswalzenpaare sowie die Formhalicwalzenpaare der Schenkel und des Gurtes in Fertigungsrichtung versetzt zueinander angeordnet sein.In order to be able to coat the entire surface of the composite element strand, the Set-up and guide roller pairs as well as the Formhalic roller pairs of the legs and the belt in Manufacturing direction be offset from one another.
Nach dem allmählichen Zusammenführen der Deckschichten und dem Ausschäumen ergibt sich eine derart hohe Eigenstabilität, daß der erhärtende Verbundelementstrang nicht eine üblicheiweise für im wesentlichen ebene Deckschichten erforderliche, nur durch aufwendige Plattenbänder erreichbare, vollflächige Abstützung erhalten muß. sondern djrch die FormhaltewalzenDaareAfter the cover layers have gradually been brought together and foamed, such a result is obtained high inherent stability, so that the hardening composite element strand is not a common for essentially level surface layers required, full-surface support that can only be achieved with complex apron conveyors must receive. but rather through the form-holding roller hairs

Weiterhin kann es zweckmäßig sein, daß mindestens einige der leuien Formhalir*alzenpaare angelrieben sind. It can also be useful that at least some of the leuien Formhalir * alzenpaaren are driven.
Gegenüber den vorbekanmen Einrichtungen für ebene Verbundelemenie können r.iit dei Vorrichtung gemäß der Erfindung mit einfachen Mitteln komplizierte Verformungen aufweisende, trogförmige Verbundelemenie, also gleiche, bei denen die Gesamihöhe ein Vielfaches der Wandstärke beträgt, hergestellt u·erden. Es können tür alle Stufen leichte, dünne Walzen verwende! werden, wobei \on sonst üblichen, aufwend»- gea das ganze Profil fassenden Walzer, abgesehen werden kann.Compared to the overhead devices for flat composite elements, trough-shaped composite elements with complicated deformations, i.e. identical ones in which the overall height is a multiple of the wall thickness, can be produced with simple means with the device according to the invention. Light, thin rollers can be used for all levels! , whereas the otherwise usual, lavish waltz, which encompasses the entire profile, can be disregarded.
