ABSTRACT:
The invention relates to a device for storage and conveyance of bulky holders (C), comprising at least one tier (32), each tier comprising at least one conveyance circuit (2) for the holders (C), and each conveyance circuit (2) comprising at least two longitudinal paths (4, 6) disposed substantially parallel to each other, for conveyance of the holders (C) in the direction of the longitudinal paths (4, 6), which longitudinal paths (4, 6) each define a first predetermined number (N) of adjoining holder positions for the holders (C) while two adjacent longitudinal paths (4, 6) of a conveyance circuit (2) slope from the same end in opposite directions, and in which transverse tracks situated at the opposite ends of the longitudinal paths and movable at least in the vertical direction are also provided, for conveyance of the holders (C) in the direction of the transverse tracks, which transverse tracks can transfer the holders (C) to and from the longitudinal paths (4, 6), and also comprising a second predetermined number (M≦2*N−1) of carriers (14) which are movable along the longitudinal paths and transverse tracks and are designed to take one or more holders (C), lifting means (34) being provided for moving the transverse tracks in the vertical direction.
