Embodiment Construction

[0038] as in the attached figure 1 with3 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 E...

Abstract

The subject of the present invention is a method and a machine for automatically inspecting and sorting non-metallic objects. The method is characterized in that it essentially consists in temporarily subjecting a surface or outer layer (4) of objects (1) travelling as a monolayer stream to the thermal radiation from at least one heating means (5) some distance away, so as to deliver, to each of these travelling objects (1), a non-impairing thermal pulse which is identical for all the objects in terms of thermal energy applied per unit area in the plane of conveying (2), then in taking at least one thermal image of each of the objects by means of at least one linear or matrix thermal detector (6), for example a thermal camera, after a specified amount of time has elapsed following application of the thermal pulse, then in classifying or categorizing each travelling object (1) according to the data contained in its thermal image(s), in delivering a control or actuation signal for each object and, finally, in separating the travelling objects (1) according to their class or category and/or according to the corresponding control or actuation signal 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...
