  • Patent number: 5586637
    Abstract: A new and improved conveying system for lifting and orienting caps comprising a conveyor belt which is formed of articulated sections and with guide rollers to support the belt with an upper lifting section having an essentially vertical path of travel and a lower loading section with an angled path of travel. Also included are sprockets on the guide rollers to effect movement of the belt in an upward path of travel through the lower section and then the upper section. Further included is a plurality of cleats secured to the exterior surface of the conveyor belts. The cleats have supporting surfaces which extend at right angles from the exterior surface of the conveyor belt for retaining bottle caps thereon in a proper orientation when the upper surface of the cap is in contact with the conveyor belt and the lower edge thereof supported on the supporting surfaces of the cleats but to effect the dropping thereof when the caps are not in the proper orientation.
