Up to now, the cleaning of the intermediate bulk containers (IBC) for powder was carried out in laborious manual work. Here, a system was developed, in which the IBCs are vacuumed from the inside by means of a robot arm. The Fanuc robot was programmed by a subcontractor. Our work included the procurement of the control cabinet, the integration of the robot, various safety elements, an extraction system as well as the entire operation and integration into the factory's control system.
