LUBRICATION SYSTEM FOR A CONVEYOR BELT Abstract of the Disclosure An optical inspection system (10) has a conveyor belt (18) that turns at a non-rotating turning bar (22). An inner surface (20) of the conveyor belt contacts a turning surface (22T) of the turning bar. A reservoir (60) for holding a lubricant (62), such as water, is formed by a free surface (22F) of the turning bar, two reservoir side walls (54, 56), a free surface (52F) of a feed bar (52), and a lower surface (58). The feed bar has orifices (69) for discharge of the lubricant into the reservoir and is connected to a source of lubricant subject to volume regulation. When the conveyor belt is in operation, the volume of lubricant suppled to the reservoir keeps the line of contact (22L) between the inner surface and the turning surface covered with lubricant. Rods (64, 66) regulate the flow of lubricant so as to maintain adequate coverage with lubricant of the region (46) where the conveyor belt turns over the turning bar and of the line of contact between the inner surface and the turning surface. The top (22H) of the turning bar is a distance (H) lower than the common level of the top (52H) of the feed bar, the top of the side walls, and the tops (64H, 66H) of the rods. The volume of lubricant supplied to the reservoir through the orifices is regulated so that the supply slightly exceeds the outflow of lubricant between the inner surface and the turning bar. Any excess flow of lubricant flows over the tops of the rods where they are not in contact with the inner surface of the conveyor belt and is captured in a catch pan or pans (72). The conveyor belt may alternatively cause the articles to move through a desired region, such as to the surface of another conveyor belt in a belt-to- belt transfer system.
