The Handling station is equipped with a flexible two-axis handling device. Work pieces inserted into the holder are detected by an optical diffuse sensor. The handling device picks up the work pieces from there with the aid of a pneumatic gripper. The gripper is equipped with an optical sensor which differentiates between “black” and “non-black” work pieces. The work pieces can be placed on different slides according to this criterion. Other sorting criteria can be defined if the station is combined with other stations. Work pieces can also be transferred to a downstream station.
