Abstract

L'invention concerne un système de tri d'articles, comprenant une région de stockage (100) et une région de travail (200), une pluralité de groupes de contenants de stockage (10) disposés en rangées et en colonnes étant disposés dans la région de stockage (100), et un passage transversal (2) étant formé entre deux rangées adjacentes de groupes de contenants de stockage (10). Du fait que le taux d'utilisation de passages transversaux à proximité de la région de travail (200) est élevé, à la fois le transport d'un contenant de stockage (1) à l'écart de la région de travail (200) et le transport d'un contenant de stockage (1) à proximité de la région de travail (200) nécessitent que les passages transversaux (2) se trouvant à proximité de la région de travail (200) soient traversés. En réglant la densité des passages transversaux (2) à proximité de la région de travail (200) pour qu'elle soit supérieure à la densité de canaux transversaux (2) à l'écart de la région de travail (200), la disposition de l'ensemble du système est plus rationnelle, ce qui permet d'empêcher efficacement l'apparition d'une congestion et de faciliter l'amélioration de l'efficacité de tri.
