Abstract

La présente invention concerne un dispositif de traitement de vieux papiers qui comprend un défibreur (14) qui désintègre des matériaux destinés à être recyclés et qui prépare de la pâte recyclée ; des réservoirs à feuilles de taille standard (11, 12) qui servent de pluralité de stockages de matériau qui stockent des vieux papiers ou des morceaux de vieux papiers, qui servent de matériaux destinés à être recyclés, et qui fournissent les matériaux destinés à être recyclés au défibreur (14) ; et une unité de commande (7) qui commande les fonctionnements des unités incluses dans le dispositif. Les réservoirs à feuilles de taille standard (11, 12) peuvent être permutés, et l'unité de commande (7) comprend une unité de permutation de fonctionnement (722) qui permute entre les réservoirs à feuilles de taille standard (11, 12) lorsqu'un des réservoirs à feuilles de taille standard (11, 12) devient incapable de fournir les matériaux destinés à être recyclés pour que les unités puissent continuer de fonctionner.
