摘要： Disclosed is a method and system for inspecting and sorting unsuitable or irregular objects in a stream of products, the system includes means for scanning the stream of products along a scan line. The scan line is formed by means of at least one light source directing light along the scan line, and means for detecting light beams reemitted by the product stream upon scanning. The scanning means includes a focusing means for concentrating the light in at least one dimension. The detecting means includes a focusing means for forming an image in an image plane. The detecting means is oriented towards the scan line such that points on the scan line form a projected scan line in the image plane and the image substantially located in the image plane is substantially focused in at least one dimension by the focusing means. The detecting means also includes a spatial filtering means that filters the image in substantially the direction perpendicular to the direction of the projected scan line.

摘要： The invention concerns a method and apparatus for sorting a stream of products by scanning this stream of products with a bundle of concentrated light and analyzing the light originating from the scanned products and a background element, wherein this background element is chosen such that the corresponding detected light signal differs from the light signals originating from the products to be sorted in at least one parameter and wherein one or more control signals are generated by shifting the background level of the observed light signals to a signal level chosen such that, in the thus obtained signal, the signal level of the signal of a scanned product to be accepted distinguishes itself from the signal level of the signal of a scanned product to be rejected.

摘要： The present invention is related to an apparatus for sorting products, in particular granular products such as raisins, blueberries but also pellets e.g. plastic pellets. The sorting apparatus comprises a supply system, a detecting system, a selecting system and a chute. The chute comprises a first guiding element having a downwardly-curved surface for guiding the stream of product moving under influence of gravity towards the detecting system and the selecting system. Optionally the chute comprises a second guiding element having a surface which is upward-curved at least over a certain distance along the movement of the stream of products, such that products which are propelled by the first guiding element and received by the second guiding element are redirected in an essentially vertical downward direction. The detection system will inspect the products when moving in a substantially vertical direction.

摘要： The present invention is related to a detection system for inspecting a continuous stream of products comprising means for determining the detection system induced variations in its output signal. The detection system comprises a reference element and an intermediate optical element, means for scanning a light beam over the product stream and, via the intermediate optical element, over the reference element and means for converting the light beams re-emitted by the product stream and by the reference element into an electrical signal. The intermediate optical element is positioned such that the light beam successively scans the product stream and at least one region of the reference element, in whatever order. Such detection system and method are of particular use in an apparatus for sorting products, where it is used to inspect products provided to the detection system in a continuous stream.
