Return device for empties
A return device for empties includes an optical capturing apparatus for optically capturing features of an empty container. The capturing apparatus includes light sources and cameras. The light sources and the cameras are arranged around a capturing region in a horseshoe-shaped manner. One of the light sources and one of the cameras are arranged such that the camera is arranged in the beam path of the light source such that, when an empty container has been brought into a capturing region, the camera captures a modified luminous energy from the light source compared to the case where there are no empty containers in the capturing region. The return device further includes a circuit connected to the plurality of cameras and configured to activate an additional camera or an additional light source of the light sources on the basis of the luminous energy captured by the camera.
