ABSTRACT:
The device, comprising a horizontal feed screw (9) and a conveyor belt (14), is of the type as used for feeding containers or bottles (11) to special machine units, typically labelers, fillers, cappers and rinsers; the screw is of mixed pitch, its exact geometry being suited to the shape and material of the container and the type of machine serviced by the device, and operates in conjunction with freely revolving rollers (10) mounted in pairs to rocker arms (8) with their axes vertical and parallel to the axis of the bottle or container, which are also able to traverse at right angles to the screw axis and pivotable about the fulcrum of the relative rocker arm, in such a way that the containers are conveyed along the belt (14) in contact with the screw on the one side, restrained and guided by the rollers on the side opposite, and emerge correctly positioned and undamaged at the runout.
