Abstract

L'invention concerne un système et un procédé de prélèvement, le système de prélèvement comprenant : une station de travail (420), la station de travail (420) comprenant au moins une station de prélèvement, la station de prélèvement étant utilisée pour traiter un récipient de stockage (741) ; une zone de stationnement de véhicule mobile (430), la zone de stationnement de véhicule mobile (430) étant utilisée pour stationner un dispositif de transport automatique (440) qui porte un véhicule mobile (460) et est déployé avec un dispositif de manipulation de récipient (450) ; le dispositif de transport automatique (440), le dispositif de transport automatique (440) étant responsable pour le transport du véhicule mobile (460) à la zone de stationnement de véhicule mobile (430) ; et le dispositif de manipulation de récipient (450), le dispositif de manipulation de récipient (450) étant configuré pour se déplacer au moins le long de la direction verticale de l'axe Y pour prélever et faire tomber le récipient de stockage (741) sur le véhicule mobile (460), ou pour déplacer le récipient de stockage (741) entre la station de prélèvement et le véhicule mobile (460). Le système de prélèvement peut réaliser le déplacement de récipients de stockage sans la participation d'un opérateur, ce qui permet de réduire l'entrée d'opérateurs tout en améliorant efficacement l'efficacité de prélèvement.
