A device (1, 15, 17) for eliminating non-conforming articles (2a, 2b) from a product stream of conforming articles and non-conforming articles (2a, 2b), which is moving in the transport direction, comprising a detection unit (5, 5a, 5b), which is configured to register the product stream, a computing unit, which is connected to the detection unit (5, 5a, 5b) and configured to receive from the detection unit (5, 5a, 5b) feature data of the product stream and to detect from the feature data in real time non-conforming articles (2a, 2b) in the product stream registered by the detection unit (5, 5a, 5b), and an elimination unit controlled by the computing unit, which is arranged - viewed in the transport direction - downstream of the detection unit (5, 5a, 5b) at the product stream and is configured to eliminate non-conforming articles (2a, 2b) from the product stream by means of at least one compressed air blast, wherein the device (1, 15, 17) has at least one further elimination unit controlled by the computing unit, which is arranged - viewed in the transport direction - downstream of the detection unit (5, 5a, 5b) at the side of the product stream opposite to the compressed air elimination unit at the product stream and is configured to eliminate non-conforming articles (2a, 2b) by partially deflecting the product stream by means of at least one deflecting element, and that the computing unit is configured to distinguish the detected non-conforming articles (2a, 2b) into non-conforming articles of a first order and non-conforming articles of a second order, wherein the compressed air elimination unit is configured to eliminate the non-conforming articles of the first order controlled by the computing unit, wherein the deflecting element elimination unit has at least one actuator, which moves the at least one deflecting element between a first position and a second position, and wherein the deflecting element in the first position projects into the product stream and is arranged outside of the product stream in the second position, wherein in the first position the conforming articles are deflected, characterized in that the computing unit is configured to determine from the feature data of the product stream the contours or shapes of the products contained in the product stream and the spectral composition of the products contained in the product stream as well as to infer from the spectral composition of the products contained in the product stream the material of the products, to infer from the contours or the shape of the products the volume of the products, to estimate from the material and the volume of the products the mass thereof and to distinguish between conforming articles, non-conforming articles of the first order and non-conforming articles of the second order by way of the mass of the products. a detection unit (5, 5a, 5b), which is configured to register the product stream, a computing unit, which is connected to the detection unit (5, 5a, 5b) and configured to receive from the detection unit (5, 5a, 5b) feature data of the product stream and to detect from the feature data in real time non-conforming articles (2a, 2b) in the product stream registered by the detection unit (5, 5a, 5b), and an elimination unit controlled by the computing unit, which is arranged -
