Abstract

Avec un dispositif pour une manutention au moins partiellement automatique de douilles de cannettes vides et de cannettes bobinées de métiers à tisser, on se propose de trouver une solution où les manipulations des cannettes terminées comme des douilles vides soient simplifiées, l'invention ayant en particulier pour objectif une automatisation aussi étendue que possible des processus d'enlèvement et de mise en place. Cet objectif est atteinnt par le fait qu'il est prévu, sur un cadre commun (12) du dispositif, un bras de prise et de transfert (8) pour les douilles vides (5), un bras de prise et de transfert (6) pour les cannettes (4) ainsi qu'un mécanisme d'actionnement et de pivotement (16 - 18) pour faire déplacer les bras (6, 8) d'une position d'arrêt à une position de transport.
