The invention relates to a device and a method for automatically inspecting objects traveling in an essentially monolayer flow. Said device comprises a detection unit (4) through which the object flow (2) passes, consisting of the following: means (6) for applying electromagnetic radiation in the direction of the plane of conveyance of said objects (2) and defining a lighting plane, the intersection of the lighting plane and plane of conveyance defining a detection line; a receiver device (8) periodically scanning each point on said detection line and receiving radiation reflected by an elementary measuring zone, the plane defined by said detection line and the optical input center being known as the scanning plane; means (10) for transmitting said reflected radiation. The machine is characterized in that the radiation emitted is concentrated in the region of the lighting plane (Pe) and in that said lighting plane (Pe) and the scanning plane (Pb) merge, whereupon said joint plane (Pe, Pb) is inclined in relation to the normal (D) of the plane of conveyance (Pc).
Le principal but de la présente invention est de proposer une machine et un procédé d'inspection, et le cas échéant de tri, fonctionnant à haut débit et pour des flux d'objets sensiblement monocouche, cette machine et ce procédé étant capables de discriminer de manière fiable des objets ayant des hauteurs significatives, tout en faisant état d'une construction et d'une mise en oeuvre qui demeurent simples et économiques.
