Objects, such as, for example, preforms for producing PET bottles, are feedable to silo as bulk material by a bulk material feeding device. A fill level sensor of the silo is connected to the control device. The control device actuates the feed drive in order to refill the silo with objects in dependence on the determined fill level of the silo. Connected downstream of the silo is an overhead conveyor and downstream of the overhead conveyor a separating-into-singles system. Both the overhead conveyor and the separating-into-singles system comprise sensors and drives, all the sensors being connected to the control device and the control device controlling all the drives.
