Abstract

Pour transporter, ainsi que amasser et stocker provisoirement, des disques (101) et portions de disque découpés en particulier d'une barre de produit (100), on utilise un dispositif de transport sur voie (50) comprenant des chariots de transport (1), en partie mobiles indépendamment les uns des autres le long des voies de guidage (51a, b) du dispositif de transport, qui servent de support de produit (1) pour les disques (101) placés lesdits chariots, lequel transport est optimisé pour collecter les disques (101) tombant après le découpage car les supports de produit (1) possèdent un élément de support (2) flexible au moins dans une direction, la direction de transport (10). L'élément de support (2) peut ainsi être facilement guidé par exemple autour d'un pignon de renvoi d'un élément de tension à circulation sans fin, tel qu'une courroie de friction (65) ou une chaîne (64) qui sert d'élément d'entraînement propre au corps de voie pour le chariot de transport passif (1), et être positionné en particulier au point d'impact des disques (101) également dans un état pas encore plat, tout en permettant d'amasser et de stocker provisoirement de tels éléments de support chargés (2) d'une manière simple et rentable.
