Abstract

A screw conveyor for transporting goods to be conveyed while hanging on hangers (10), in particular items of clothing hanging on clothes hangers, comprises a screw shaft strand (20) which is rotatably mounted about its shaft axis (22) and on whose outer surface a conveyor thread system (24) that winds in the manner of a screw around the shaft axis is formed. The hangers can be hooked into the conveyor thread system with upper hanger hooks (18) and can be conveyed axially therein in a conveying direction (14) as a result of rotation of the screw shaft strand. At least one separating region (52) used for separating the hangers (10) and having an individual conveyor groove (68) formed for the individually conveyance of the hangers is formed along the screw shaft strand. According to the invention, the conveyor thread system for directing the hangers into the individual conveyor groove forms a directing conveyor thread (70) for the hangers which tapers in the manner of a funnel along the turns direction of the conveyor thread system and which, at least on part of its length running in the turns direction, at its front edge relative to the conveying direction, adjoins the individual conveyor groove in a substantially rib-free manner. If a plurality of hangers (10-1, 10-2, 10-3) run into the directing conveyor thread, then the leading one (10-1) of these hangers in the conveying direction is directed into the individual conveying groove as the screw shaft strand rotates. The hangers are supplied continuously and without gaps to a conveyor thread system.
