Disclosed is a conveying device including an upstream conveying unit for receiving products from at least one upstream station, an accumulation surface along which the upstream conveying unit circulates, a loading unit for moving the products from the upstream conveying unit to the accumulation surface, a downstream conveying unit for clearing the products, and an unloading unit for moving the products from the accumulation surface to the downstream conveying unit. The downstream conveying unit includes a plurality of independent moving unit receiving the products in receiving zones which are successively distributed from the edge of the accumulation surface opposite the edge along which the upstream conveying unit extends. Also disclosed is a corresponding method.
