Abstract: A method for targeted detection and segregation of individual piece goods being conveyed in a conveying direction on an extensive conveying element. A position-determining device detects positional information of the piece good to be segregated. The piece good to be segregated is displaced transversely to the conveying device by a push element, which is moved transversely to the conveying direction into the conveying region of the piece goods. Before pushing of the piece good, the push element is now moved into a forward position that lies above the conveying element in the conveying region. The piece good is subsequently pushed by the push element over the conveying element by way of accelerating the push element out of the forward position in a push direction. The forward position is set by a control device depending on positional information concerning the piece good to be segregated on the conveying element.
