Identification method and device for full or empty bottle-like containers of material having different upper shapes or sizes in static or moving groups

摘要

The method involves placing an axially elastically supported pressure part (2) of a selector head (13) onto each container (1) from above onto a reference point of the container accessible as a reference surface so that a measurement part (4) comes into contact with another point on the container defined for a specific container. The axial displacement of the measurement part with respect to the pressure part is detected.
