A rotating handling carousel includes a transfer device arranged on the outer circumference of the handling carousel. The transfer device includes a carry-along element which receives and transports an article and a guide element. The guide element is arranged in such a way that the article transported by the carry-along element is guided into or out of a handling station, for which the guide element extends into an area of the handling station in such a way that the guide element does not collide with the handling device at the transfer position. A sensor detects whether a handling device or the article are not in the transfer position, and/or whether the article is located in the handling station at all, and, after such a determination, issues a collision signal based on a kind of the transfer device.
