SORTER AND METHODS OF SORTING Russian patent published in 2009 - IPC B07C5/36 

FIELD: mechanics.

SUBSTANCE: proposed sorter passes the flow of product particles through the concentrator onto tapered scattering plate which feeds the product in the form of a uniform, circular monolayer to collimator comprising a product inner and outer guides to create a circular flow of products directed vertically. There is a unit of detectors in the said flow of products comprising an upper detector and optical unit (33). A rotary beam-splitting mirror is fitted below the said optical unit to scan the product in the circular zone of registration. The product passing through the registration zone is bombarded by the source, and the signal from the reflected or passed light is then measured by the detector of unit of detectors and optics. The classified product is removed from the flow by a rejecter in response to the control signal of the pickup incorporated with the aforesaid unit of detectors and optics. The classified product comes into the bin towards one side of the separating plate, the remaining products being directed free into the said bin.

EFFECT: higher quality of products sorting in flow.
