Abstract: A method of manually sorting flat articles (4) into a sorting case (7) comprising sorting slots (8) consists in generating an identification signal (100) designating a sorting slot of said sorting case, into which slot said article to be sorted is to be placed, and then placing said flat articles to be sorted in a stack and in taking the articles one-by-one from the top of the stack. The method also consists in automatically forming (310) digital images (14) of the top of the stack at a certain rate, the digital image of each article of the top of the stack including a sorting indication. Finally, on the basis of the digital image of said article on the top of the stack, the method further consists in automatically generating (330) said identification signal as a flat article is being taken from the top of the stack of flat articles.

Abstract: A sorting machine (1) for sorting flat articles (2) on edge, which machine includes an upstream conveyor (10), and a downstream conveyor (30) that conveys the flat articles (2) by nipping them, the upstream conveyor (10) and the downstream conveyor (30) being separated by detector means (100) including an intermediate conveyor (20) provided with intermediate belts (22) that convey said flat articles (2) by nipping them, and that are associated individually with suction means (24, 25) pressing any flat article (2) against one or the other of said intermediate belts (22), image capture means (26) for capturing images of the bottoms of said flat articles (2) passing between the intermediate belts (22), and analysis and processing means (4) for analyzing and processing said images to detect any bunching of said flat articles (2).

Abstract: The unstacker device (1) for unstacking flat articles comprises: a magazine (3) in which the articles (2) to be unstacked are disposed on edge in a stack against a jogging edge (5) and facing an unstacking plate (4) arranged to separate a first article (2A) and to drive it in a certain unstacking direction (A) that is perpendicular to the jogging edge (5); a conveyor (7) for conveying the unstacked articles, the conveyor having an inlet (7A) downstream from the jogging edge (5); and retaining means (8) disposed between the jogging edge (5) and the inlet of the conveyor (7A) and actuated to exert a retaining force on an article (2A, 2B), which retaining force opposes movement of the article.

Abstract: Image acquisition apparatus (1) for acquiring images of mailpieces (P), the apparatus comprising a housing (3) inside which the following are placed: a first camera (4) co-operating with a first lighting system (8) emitting light radiation at a certain wavelength suitable for exciting a fluorescent mark to acquire an image of the surface of a mailpiece through a first window (5); a second camera (6) co-operating with a second lighting system (9) emitting light radiation in the visible light domain to acquire an image of the surface of a mailpiece through a second window (7); and means (10) for preventing light interference, which means are concave in shape and are disposed between the first window and the second window, the second lighting system (9) being disposed in the cavity of said means (10) for preventing light interference.

Abstract: An image acquisition system for identifying signs on mailpieces wherein each mailpiece is moved by being nipped between a conveyor and a housing wall that is provided with a longitudinal slot, comprises, inside the housing, an illumination module having two lighting units that are symmetrical about the slot for the purpose of illuminating a surface defined by the slot, and a camera for forming an image of said illuminated surface, polarization optical means also being disposed between said illumination module and said illuminated surface, and a polarization optical filter being disposed between said camera and said surface. The slot is closed by a flush transparent rigid wall against which each mailpiece is pressed.
