Summary:An assembly for detection of foreign bodies in a multihead weigher includes an image recorder and a lighting module and an image evaluation module. The multihead weigher includes weighing containers for filling with bulk material, a selection of the bulk material being emptiable into chutes combined in the shape of a funnel upon arrival of a trigger signal. The image recorder records an image series, and the lighting module and the image evaluation module output a signal upon detection of a foreign body in the image series. The image recorder includes one or more cameras for optical capturing of the funnel, the one or more cameras being arranged inside of or above the funnel and being set up to capture one or more sections of an interior surface of the funnel between two horizontal planes.
