Title (EN) ARTICLE IRRADIATION SYSTEM WITH AN ARTICLE TRANSPORTING CONVEYOR
(FR) SYSTEME D'IRRADIATION D'ARTICLES MONTE SUR LE CONVOYEUR LES TRANSPORTANT
Abstract:
(EN) An article irradiation system includes a radiation source (10) for scanning a target region (23) with radiation; a first conveyor system (12) for transporting articles from a loading area (22) through the target region to an unloading area (24); and radiation shielding material defining a tunnel closely encompassing portions of the conveyor system extending away from the target region toward the loading and unloading area for shielding the loading and unloading areas from the radiation source. The first conveyor system (12) is disposed in a path having curved turns between the target region and loading and unloading areas that the shielding material precludes a direct line of sight between such. A second conveyor system is coupled to the first conveyor system for transporting the articles from a first position to a second position on the first conveyor system that is before the target region and reorientates the article transported by the first conveyor system by one-hundred-eighty degrees. A radiation shielding assembly (13) has a radiation shield which defines a corridor through which an electron beam is scanned.
(FR) L'invention porte sur un système d'irradiation d'articles comprenant une source de rayonnement (10) balayant une zone cible (23); un premier système de convoyage (12) transportant les articles d'une aire de chargement (22) à une aire de déchargement (24) en passant par la zone cible, et un matériau de blindage anti-rayonnement délimitant un tunnel entourant de près les parties du système de convoyage reliant la zone cible aux aires de chargement et de déchargement pour les protéger de la source de rayonnement. Le premier système de convoyage (12) suit une trajectoire comportant des courbes entre la zone cible et les aires de chargement et de déchargement de manière à ce que le matériau de blindage empêche une communication visuelle directe entre elles. Un deuxième système de convoyage, relié au premier, assurant le transport d'articles entre une première position du premier système de convoyage et une deuxième située avant la zone cible, réoriente les articles transportés par le premier système de convoyage dans une direction à 180°. L'invention porte également sur un système de blindage anti-rayonnement (13) comportant un blindage délimitant un couloir que balaye un faisceau d'électrons.
