The invention pertains to a stocking system and collection device consisting of a linear conveyor system and a second linear conveyor system parallel to the first and placed in alignment with it so that an object placed on the first conveyor system may be transferred to the second conveyor system. In accordance with the invention, the means are anticipated to move the second conveyor system perpendicularly to the direction of the conveyance so that the second conveyor system can be move from a position situated in alignment with the first conveyor system to a position for distribution. It is preferable that the first conveyor system (100) consist of three parallel belts (110, 120, 130) placed side by side; the first (110) and the third (130) belts extend farther in advance in the direction of the second conveyor system (200) at a distance (d) than the second belt (120). Similarly, the second conveyor system (200) consists of three parallel conveyor belts (210, 220, 230) placed side by side; the first (210) and the third (230) belts extend less in behind, in extension, one after the other, and the second belts (120, 220) at least partially extend one after the other; the first drivers are anticipated to drive the three belts of the first conveyor system and the second drivers are anticipated to drive the two belts of the second conveyor system in the same movement.
