Abstract

La présente invention concerne une trémie permettant d'alimenter des pièces à usiner (w) vers un dispositif de transport de pièces à usiner (6) lorsque la quantité résiduelle des pièces à usiner (w) au niveau du dispositif de transport de pièces à usiner (6) est diminuée. Ladite trémie comprend une partie de stockage de pièces à usiner (110) permettant de stocker les pièces à usiner (w), une sortie de pièces à usiner (112) formée dans la partie de stockage de pièces à usiner (110) et permettant aux pièces à usiner d'être déchargées, un élément d'élévation (120) constituant la partie inférieure de la partie de stockage de pièces à usiner (110) et s'élevant dans la partie de stockage de pièces à usiner (110), et une partie d'entraînement permettant d'élever l'élément d'élévation. Dans ladite trémie, les pièces à usiner sont alimentées à partir de la sortie de pièces à usiner (112) vers le dispositif de transport des pièces à usiner (6) par l'élévation de l'élément d'élévation (120), la quantité des pièces à usiner (w) introduite dans le dispositif de transport de pièces à usiner (6) pouvant ainsi être déterminée en fonction de la hauteur d'élévation de l'élément d'élévation (120).
