ABSTRACT:
This invention has as its object an automatic process and machine for inspecting and sorting non-metallic objects. Process characterized in that it consists essentially in temporarily subjecting a surface or outside layer (4) of objects (1) passing in a single-layer stream to the caloric radiation of at least one remote heating means (5), so as to deliver to each of these passing objects (1) a non-altering heat pulse that is identical for all of the objects in terms of heat energy applied per unit of surface area in the conveying plane (2), then to acquire at least one thermal image of each of said objects by means of at least one linear or matrix thermal sensor (6), for example a thermal camera, this after a determined length of time has elapsed following the application of the heat pulse, then to classify or to categorize each passing object (1) based on data contained in its thermal image or images and to deliver a control or actuation signal for each object and, finally, to separate the passing objects (1) based on their class or category and/or the corresponding control or actuation signal that is delivered.
