Abstract

L'invention a pour objet de réaliser une logique d'arrimage pour arrimer de manière efficace des contenants d'articles ayant des tailles indéfinies sur une caisse-palette à roues, etc. Le dispositif de chargement d'article comprend : un dispositif d'information de gestion de chargement/déchargement d'article accompagné d'informations d'identification individuelle d'articles contenant des informations de contenant d'article ; une unité de commande de traitement d'informations de logique de chargement qui, après avoir effectué un placement planaire (chargement de la première couche) dans lequel un contenant d'article qui possède des surfaces supérieure et inférieure plates et lisses est chargé sur un corps de placement en se basant sur lesdites informations d'identification individuelle d'article, reconnaît la partie de surface sensiblement supérieure (région plane) d'un contenant d'article ayant la plus petite hauteur de contenant d'article parmi les contenants d'article placés comme une « carte d'espace vides » où un contenant d'article est à charger ensuite dans un chargement de deuxième couche, et qui répète le placement planaire des contenants d'article ; et un robot de chargement qui fonctionne conjointement avec le dispositif d'informations de gestion de chargement/déchargement et l'unité de commande de traitement d'informations.
