Abstract

La présente invention concerne un dispositif de gestion d'objet comprenant une unité de gestion d'objet qui, sur la base d'informations d'installation de support exprimant une correspondance entre une machine-outil et un support pour placer un objet, change des données incluses dans des informations d'objet comprenant l'emplacement et le poids de l'objet ; et une unité de réception qui reçoit une notification de retrait lorsque l'objet est retiré de la machine-outil.　Dans un cas dans lequel un signal de retrait est reçu : lorsque le poids de l'objet est inférieur ou égal à un seuil prédéterminé, l'unité de gestion d'objet règle l'emplacement de l'objet dans les informations d'objet de telle sorte que l'emplacement est commuté de la machine-outil au support pour placer l'objet, et l'unité de gestion d'objet règle l'emplacement de l'objet dans les informations d'objet à une position différente du support pour placer l'objet lorsque le poids de l'objet est supérieur au seuil. Le "support pour placer l'objet" est un support sur lequel un objet à transporter est placé par un transporteur automatique ; et la "position différente du support pour placer l'objet" est une position dans laquelle un objet ne devant pas être transporté est placé par le transporteur automatique.
