Title (DE) VERFAHREN UND VORRICHTUNG ZUR PRODUKTION VON FASERVERBUNDWERKSTOFF AUFWEISENDEN WERKSTÜCKEN
(EN) METHOD AND DEVICE FOR PRODUCING WORKPIECES COMPRISING FIBRE COMPOSITE MATERIAL
(FR) PROCÉDÉ ET DISPOSITIF DE PRODUCTION DE PIÈCES COMPORTANT UN MATÉRIAU COMPOSITE RENFORCÉ DE FIBRES
Abstract:
(DE) Bei einem Verfahren zur Produktion von Faserverbundwerkstoff aufweisenden Werkstücken, bei dem eine von Haltemitteln (97) einer Fördereinrichtung gehaltene Basiseinheit (5) durch mindestens eine Applikationsstation (2, 14, 17, 20, 23, 27, 29,2, 14, 17, 20, 23, 27, 29, 39-41, 67-72) geführt wird, und zur Bildung der Werkstücke an der Applikationsstation (2, 14, 17, 20, 23, 27, 29,2, 14, 17, 20, 23, 27, 29, 39-41, 67-72) oder an mindestens einer der Applikationsstationen (2, 14, 17, 20, 23, 27, 29,2, 14, 17, 20, 23, 27, 29, 39-41, 67-72) während einer Translationsbewegung der Basiseinheit (5) durch die betroffene Applikationsstation (2, 14, 17, 20, 23, 27, 29,2, 14, 17, 20, 23, 27, 29, 39-41, 67-72) mindestens ein zum Faserverbundwerkstoff gehörendes Band (6) auf die Basiseinheit (5) abgelegt wird, wird vorgeschlagen, dass in Förderrichtung vor der Applikationsstation (2, 14, 17, 20, 23, 27, 29,2, 14, 17, 20, 23, 27, 29, 39-41, 67-72) oder vor mindestens einer der Applikationsstationen (2, 14, 17, 20, 23, 27, 29,2, 14, 17, 20, 23, 27, 29, 39-41, 67-72) die räumliche Ausrichtung der Basiseinheit (5) mittels mindestens einer Rotation relativ zu den Haltemitteln (97) geändert wird. Des Weiteren wird eine hierfür geeignete Vorrichtung vorgestellt.
(EN) In a method for producing workpieces comprising fibre composite material, in which a base unit (5) held by retaining means (97) of a conveying device is guided by at least one application station (2, 14, 17, 20, 23, 27, 29,2, 14, 17, 20, 23, 27, 29, 39-41, 67-72) and, in order to form the workpieces at the application station (2, 14, 17, 20, 23, 27, 29,2, 14, 17, 20, 23, 27, 29, 39-41, 67-72) or at least at one of the application stations (2, 14, 17, 20, 23, 27, 29,2, 14, 17, 20, 23, 27, 29, 39-41, 67-72), during a translational movement of the base unit (5) through the application station (2, 14, 17, 20, 23, 27, 29,2, 14, 17, 20, 23, 27, 29, 39-41, 67-72) in question at least one strip (6) belonging to the fibre composite material is placed on the base unit (5), it is proposed that the spatial orientation of the base unit (5) is altered by means of at least one rotation relative to the retaining means (97) before the application station (2, 14, 17, 20, 23, 27, 29,2, 14, 17, 20, 23, 27, 29, 39-41, 67-72) or before at least one of the application stations (2, 14, 17, 20, 23, 27, 29,2, 14, 17, 20, 23, 27, 29, 39-41, 67-72) in the conveying direction. The invention furthermore relates to an apparatus suitable therefor.
(FR) L’invention concerne un procédé de production de pièces comportant un matériau composite renforcé de fibres, selon lequel une unité de base (5) maintenue par des moyens de maintien (97) d’un équipement de transport est guidée à travers au moins une station d’application (2, 14, 17, 20, 23, 27, 29,2, 14, 17, 20, 23, 27, 29, 39-41, 67-72), et au moins un ruban (6) appartenant au matériau composite renforcé de fibres est déposé sur l’unité de base (5) à la station d’application (2, 14, 17, 20, 23, 27, 29,2, 14, 17, 20, 23, 27, 29, 39-41, 67-72) ou à au moins une des stations d’application (2, 14, 17, 20, 23, 27, 29,2, 14, 17, 20, 23, 27, 29, 39-41, 67-72) durant un mouvement de translation de l’unité de base (5) à travers la station d’application (2, 14, 17, 20, 23, 27, 29,2, 14, 17, 20, 23, 27, 29, 39-41, 67-72) correspondante pour la réalisation des pièces. Selon l’invention, l’orientation spatiale de l’unité de base (5) est modifiée au moyen d’au moins une rotation par rapport aux moyens de maintien (97) dans la direction de transport avant la station d’application (2, 14, 17, 20, 23, 27, 29,2, 14, 17, 20, 23, 27, 29, 39-41, 67-72) ou avant au moins l’une des stations d’application (2, 14, 17, 20, 23, 27, 29,2, 14, 17, 20, 23, 27, 29, 39-41, 67-72). L’invention concerne par ailleurs un dispositif approprié à ce procédé.
