  • Patent number: 5400895
    Abstract: An endless transport conveyor for sorting tobacco containers, specifically sheets and bales. The tobacco container sorting conveyor includes an endless foraminous belt with top and bottom runs, a slotted support located below the top run, a collecting pan located below the support and a motor for driving the endless belt. A supply conveyor is adjacent one end of the transport conveyor and loads the tobacco containers onto the belt. As the tobacco containers are conveyed, tobacco particles that fall through the belt and support are received on the collecting pan. Diverting assemblies mounted along one side of or above the belt selectively divert the tobacco containers, via the input from sensors, into station chutes mounted along one or both sides of the belt and opposite from each diverting assembly. An end chute and bin may extend from the end of the transport conveyor or opposite the supply conveyor for collecting tobacco waste too large to fall through the belt.

  • Patent number: 5399222
    Abstract: A belt conveyor leads past a processing station. Printing products lie on the conveyor belt in an imbricated formation, each printing product lying on the preceding one with edges to of the printing products running at an angle to the conveying direction of the belt conveyor. As a result of this incline, the printing products are exposed in a surface region and in the sections of the edges. Printing products are acted upon mechanically in the work station in these exposed regions. Individual printing products are thus taken up in a trouble-free manner and detached from the imbricated formation.

  • Patent number: 5351802
    Abstract: A system for detecting and removing metal objects from a continuously moving conveyor belt. The system includes mechanisms for lowering a scraper blade and for raising an assembly of horizontally disposed idlers mounted on a movable platform, which are activated simultaneously upon the approach of a metal object traveling on the belt. The idlers, when raised, cause a section of the belt, which is otherwise trough-like in shape, to flatten. The flattened section of the belt and the blade, in its lowered position, are disposed in close proximity to each other. The metal object and overburden moving with it on the flattened section of the belt are forced against the scraper blade. Set at an acute angle to the belt centerline, the blade deflects the metal object and overburden contaminated by it laterally, causing them to slide first onto an unsupported portion of the belt and then gently off of the belt itself.

  • Patent number: 4711357
    Abstract: An automated system and method for transporting and sorting various types of articles, such as parcels and sacks of mail. The system is comprised of a primary conveyor track and a plurality of secondary conveyor tracks which intersect the primary conveyor track at selected locations therealong. Each secondary track has associated therewith a diverter mechanism for diverting selected articles from the primary track to a corresponding secondary track, depending upon the final destinations of the articles. The diverter mechanism includes a diverter arm, which pivots across the primary track to divert selected articles to the corresponding secondary track. The deflecting surface of the diverter arm includes a motor-driven belt, the bottom edge of which is positioned within 1/4 inch of the surface of the track so that articles of irregular shape, such as sacks of mail, do not become trapped between the bottom edge of the diverter arm and the track.
