Abstract

Dans la présente invention, les positions des corps de rouleau, qui sont stockés dans une zone de stockage, à l'intérieur de la zone de stockage sont gérées par l'utilisation d'étiquettes RFID fixées aux corps de rouleau. Lorsqu'un rouleau de papier (200) ayant une étiquette RFID (120) fixée à celui-ci est stocké dans une zone de stockage, son code d'identification est lu par un premier lecteur RFID (193), et sa position de stockage est stockée dans une base de données (160) en association avec le code d'identification. Lorsque le rouleau de papier (200) doit être utilisé, le rouleau de papier est transporté vers une position de mise en place prédéterminée par un moyen de transport (chariot élévateur (190) sans pilote et corps de transfert (460)). Le code d'identification est lu par un second lecteur RFID (20) disposé au niveau de la position de mise en place, et une unité de comparaison (70) compare le code d'identification au type correct de corps de rouleau à placer dans la position de mise en place et délivre le résultat de comparaison. Une unité de sortie de détermination (80) génère une sortie indiquant la propriété du type de rouleau de papier (200) placé dans la position de mise en place en fonction du résultat de comparaison.
