Patent ID: 11938520

Abstract:
An automatic machine (2) for processing objects (3) passing in a flow (F) on a conveyor (4) has a selective ejection device (1) with at least one bar (5) with nozzles (6) that is disposed transverse to the direction of said flow (F), after the outlet or tipping end of said conveyor (4), and having an active surface strip (7) that corresponds to the installation region of the outlet openings (6′) of the nozzles (6) of the pneumatic bar (5), this surface strip (7) being situated beneath the conveying plane (4″) of the conveyor (4). This machine has a device (8) for cleaning at least said surface strip (7), this cleaning device (8) having at least one cleaning head (9) that is able to move in translation along the longitudinal axis (AL) of the bar (5) and at least over the entire extent of the installation or overlap region, said or each cleaning head (9) comprising at least one scraping member (10), which moves in contact with at least said surface strip (7), and at least one nozzle for blowing air of which the pressurized jet is directed toward said surface strip (7) and precedes the scraping member (10) during the movement of the mobile cleaning head (9).
