Abstract: The invention relates to a robotic method for loading cases on a packaging line from cases contained in a closed parallelepiped container and wherein it is proceeded with the loading of the packaging line, after opening of the container (Ca) by: /d/ insertion of a first jaw (30) of the clamp between the first face (F1) of the container and the first case (Et1) of the row of cases and, insertion of a second jaw (31) of the clamp between the last case (Etd) of the row of cases and the second face (F2) of the container, and approach of the jaws until seizing up the row of cases, /e/ piloting of the robotic arm so as to extract the row of cases from the container grasped by the motor-driven clamp (3) and load the packaging line (Lg) with the row of cases.
