In the case of a central belt system (1) with article shafts (2), ejectors (5), moving central belt (4) and central control unit (6), an automatic control system (7′) which is connected to the control unit (6) for articles to be controlled on the moving central belt (4), with a connected image processing unit (8), and a camera system (9, 10) possibly in addition with an illumination system (11). The camera and illumination systems (9, 10) are set in such a way, and the articles to be controlled which are arranged chaotically on the central belt (4) are ejected by the ejectors (5) in such a way, that optical shadow formation at the article to be controlled on the central belt (4) is preferably just prevented.
