1. An automatic machine for processing, sorting or inspecting, objects passing in a direction of flow on a conveyor, this machine having a selective ejection device with at least one pneumatic bar or rail with nozzles, said at least on pneumatic bar or rail being disposed transverse to the direction of said flow, after an outlet or tipping end of said conveyor, and having an active surface strip that corresponds to an installation region of outlet openings of the at least one pneumatic bar or rail with nozzles, said active surface strip being situated beneath a conveying plane of the conveyor,
said machine also comprises a cleaning device for cleaning said active surface strip, this cleaning device having a cleaning head that is able to move in translation along a longitudinal axis of the at least one pneumatic bar or rail and at least over an entire extent of an installation or overlap region, said cleaning head comprising at least one scraping member, which moves in contact with said active surface strip, and a plurality of blowing nozzles for blowing air, said blowing nozzles generating a pressurized jet that is directed toward said active surface strip and precedes the scraping member during movement of the cleaning head so as to process at least said active surface strip in order to remove deposits present on the active surface strip,
wherein the scraping member is in the form of a flexible and elastically deformable blade and is arranged in a plane substantially perpendicular to the longitudinal axis of the at least one pneumatic bar or rail, wherein the plurality of blowing nozzles are mounted in a support body of the cleaning head, wherein the support body bears said scraping member, and wherein the blade comprises two faces that face in opposite directions,
wherein the pressurized jet is oriented such that expelled air of the pressurized jet simultaneously strikes the active surface strip and one of the faces of the scraping member, and wherein said expelled air is directed toward an edge of said one of the faces of the scrapping member, and
wherein said plurality of blowing nozzles includes nozzles located on opposite sides of the scraping member, and wherein said opposite sides are separated by the blade.
