Abstract Pivotally mounted above the framework of a power-driven horizontal endless belt conveyor is a power-driven vertical endless belt bag shifting device adapted to be swung over the horizontal belt conveyor for engagement with filled bags proceeding therealong. Such engagement causes the bag shifting belt to carry the bags across the horizontal conveyor to a discharge ramp or other points of disposal or further transfer. Where it is desired to turn vertically standing bags around their vertical axes as they proceed along the horizontal conveyor, a bag turner is mounted above and on the opposite side of the horizontal conveyor from the vertical bag shifting belt device, the ribbed or otherwise roughened surface of which acts as a fulcrum engaging and retarding the forward travel of one side of the bag while the endless vertical bag shifting belt swings the other side of the bag in a forward direction so as to turn the bag through an angle of approximately 90*.
A device adapted to operate cooperably with a moving conveyor for shifting relatively to the conveyor the positions of bags traveling therealong, said device comprising a support adapted to be positioned adjacent the conveyor, an elongated structure mounted on said support and adapted to extend over the conveyor in the path of travel of bags traveling thereon, said elongated structure being pivotally mounted on said support for swinging laterally relatively thereto in a substantially horizontal path, a pair of rotary members rotatably mounted on said elongated structure with their axes of rotation disposed vertically in horizontally spaced parallel relationship, an endless bag shifting belt trained around said rotary members and having a bag gripping surface thereon, a motor drivingly connected to one of said rotary members, and a stationary bag turner mounted on the opposite side of the bag travel path on the conveyor in spaced relationship to said bag shifting belt and having a bag gripping portion thereon disposed in fulcrum relationship to the baGs being moved by said belt, said bag turner including a stationary horizontally elongated member adapted to be disposed approximately parallel to the direction of travel of the conveyor.
