The invention relates to a method of, and an apparatus for, controlling the transportation of a plurality of articles (Se-1.1, Se-1.2, etc). Each article has provided on it the specification of a destination to which the article is to be transported. Each article passes through a sorting installation (AnI-O, AnI-1, Anl-2) at least twice. During both passages through the sorting installation, a respective image of the article is generated, and this image comprises an image of the destination specification (ZP-1.1, ZP-1.2,etc.). As the article first passes through the sorting installation, the destination specification is read. This reading result is stored on an interim basis. As the article passes through the sorting installation again, an interim-storage reading result is determined. The reading results control the transportation of the articles. A check is made, according to the invention, as to whether an article has been misdirected. The method further establishes why an article was misdirected - incorrect reading result, incorrect determination of the reading result or transportation error.
L'invention concerne un procédé et un dispositif pour commander le transport de plusieurs objets (Se-1.1, Se-1.2,...). Une spécification d'un point de distribution où l'objet doit être transporté est apposée sur chaque objet. Chaque objet parcourt au moins deux fois une installation de tri (Anl-0, Anl-1, Anl-2). À chacun des deux passages, on produit une image de l'objet qui comprend une image de la spécification du point de distribution (ZP-1.1, ZP-1.2,...). Lors du premier passage de l'objet, on lit la spécification du point de distribution. Ce résultat de lecture est provisoirement mémorisé. Lors du passage suivant de l'objet à travers l'installation de tri, on estime le résultat de lecture provisoirement mémorisé. Les résultats de lecture commandent le transport des objets. Selon l'invention, on contrôle si un objet a été mal dirigé. Le procédé établit en outre les raisons d'une fausse direction de l'objet : résultat de lecture incorrect, estimation incorrecte du résultat de lecture ou erreur de transport.
