Abstract
Description
Die Erfindung betrifft ein Verfahren und eine Vorrichtung zum Trennen, insbesondere zum partiellen Anheben einer Deckfolie von mit Harz getränkten Faserverbundwerkstoffen, wobei die Trennvorrichtung so zur Wirkung gebracht wird, dass im Kantenbereich bereits zugeschnittener harzimprägnierter Faserverbundwerkstoffe dieser Bereich sicher erfasst, die Deckfolie partiell angehoben und vom darunter liegenden, harzgetränkten Faserverbundwerkstoff sicher gelöst wird.The invention relates to a method and a device for separating, in particular for partially lifting a cover sheet of resin-impregnated fiber composites, wherein the separating device is brought to effect so that in the edge region already tailored resin impregnated fiber composites this area safely detected, the cover sheet partially lifted and from underneath, resin-impregnated fiber composite material is safely dissolved.
Aus dem Stand der Technik sind eine Reihe von Verfahren und Vorrichtungen bekannt, die das Ablösen bzw. Trennen einer Folie von einer darunter liegenden Schicht zum Ziel haben. So wird in
Eine Vielzahl beschriebener Erfindungen beziehen sich auf das Vereinzeln der jeweiligen oberen Lage eines Stapels, insbesondere in der Papier- und Textilindustrie. Zur Erfassung der jeweiligen oberen Lage werden technische Hilfsmittel genutzt, die sich auf physikalische Grundprinzipien zurückführen lassen. So ist die Anwendung von Blas- und Saugluft, die Anwendung elektrostatischer Effekte, der Einsatz spezieller Nadeln oder Greifer mit dem Kletteffekt sowie das Anfrieren der obersten Lage unter Schutz gestellt. Beispielgebend hierzu soll die
Der Erfindung liegt die Aufgabe zu Grunde, eine Vorrichtung zu schaffen mit der es möglich ist, insbesondere bei der Verarbeitung mit harzimprägnierten Faserverbundwerkstoffen, die zum Schutz der Imprägnierung und des Faserverbundes einseitig oder beiderseits mit einer Schutzfolie kaschiert sind und durch den mit dem Harz verbundenen Klebeeffekt mit hohen Haftkräften aneinander haften, für den weiteren Verarbeitungsprozess partiell im Kantenbereich abzulösen, so dass es möglich wird, die Folie in diesem Bereich zu erfassen und abzuziehen.The invention is based on the object to provide a device with which it is possible, especially when processing with resin-impregnated fiber composites, which are laminated on one side or both sides with a protective film to protect the impregnation and the fiber composite and by the adhesive effect associated with the resin Adhere to one another with high adhesive forces, partially detach in the edge region for the further processing process, so that it is possible to capture the film in this area and deduct.
Erfindungsgemäß wird die Aufgabe dadurch gelöst, dass im ersten Verfahrensschritt der Zuschnitt im Kantenbereich mit Druckluft angeblasen wird und im zweiten Verfahrensschritt dieser Bereich mittels Vakuumsauger erfasst und abgezogen wird. Der erfindungsgemäße Gedanke kann ebenfalls dadurch realisiert werden, dass die Deckfolie im Kantenbereich im ersten Verfahrensschritt partiell mit Kältemitteln kurzzeitig weit unterhalb der Raumtemperatur abgekühlt wird und im zweiten Verfahrensschritt unmittelbar anschließend mittels Vakuumsauger (
Das erfindungsgemäße Verfahren und die technische Ausführung der Vorrichtung zur Realisierung des Verfahrens können bei der Verarbeitung von mit ein- bzw. beiderseits mit Decklagen geschützten Faserverbundwerkstoffen angewendet werden, bei dem insbesondere nach dem Zuschnitt diese Decklagen ein- bzw. beiderseits im nachfolgenden Verarbeitungsprozess abgelöste werden müssen.The inventive method and the technical embodiment of the device for implementing the method can be used in the processing of one or both sides with cover layers protected fiber composites, in particular after cutting these cover layers one or both sides in the subsequent processing process must be replaced ,
Das erfindungsgemäße Verfahren und die erfindungsgemäße Vorrichtung zur Reallasierung des Verfahren sollen nachfolgend an einem Beispiel näher erläutert werden. Hierzu zeigen:The method according to the invention and the apparatus according to the invention for real-glazing the method will be explained in more detail below using an example. Show:
Im ersten Verfahrensschritt wird der ein- bzw. beiderseits mit Decklagen
