Embodiment Construction

[0038] as in the attached figure 1with 3 As particularly illustrated, the present invention relates to an automatic method for the inspection and classification of non- Metal objects 1 in order to perform at least one type of discrimination or identification at the level of these objects based on at least one compositional or structural feature of these objects.

[0039] More particularly, the method essentially consists in temporarily subjecting a surface or outer layer 4 of said object 1 to the thermal radiation of at least one remote heating device 5, so as to transmit non-alternating heat pulses to these passages. on each of the objects 1, and said heat pulse is identical for all objects in terms of the heat energy applied per unit surface area in the conveying plane 2; Obtain at least one thermal image (thermal image) of each of said objects by a linear or matrix thermal sensor 6 such as a thermal camera; then, according to the data contained in its thermal image, the ...

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.

Description

technical field [0001] The present invention relates to the identification and continuous physical classification of objects, articles, products, or mixed analogues thereof into categories, and more particularly, to the automatic real-time sorting of said objects, articles, and / or products through a stream of products. [0002] The object of the present invention is to provide an automatic method and a device for the inspection and classification of non-metallic objects belonging to at least two different classes, in particular of different thicknesses. Background technique [0003] Many automatic methods and devices for inspection and classification are known, which use different types of electromagnetic radiation and analyze the radiation reflected or passed through the horizontal plane of the flow of objects. Devices of this type are disclosed in French Patent No. 2822235 and in Patent Application Nos. WO02, 074452 of the Pellenc Company. [0004] Known methods and devic...
