Abstract:
An apparatus is disclosed for positioning randomly oriented, asymmetrically-shaped articles in the same orientation, the apparatus comprising at least first and second oppositely arranged conduits dimensioned to receive the articles therein. Each conduit has an inlet end, and the inlet ends of the at least first and second conduits are spaced-apart to define an opening therebetween for receiving therein, one at a time, a plurality of asymmetrically-shaped articles that are randomly oriented in at least first and second orientations. Suction is created in both of the conduits, the suction being sufficient to selectively draw articles oriented in the first orientation from the opening into the inlet end of the at least first conduit, and sufficient to draw articles oriented in the second orientation from the opening into the inlet end of the at least second conduit, such that articles in the at least first and second conduits are all identically oriented relative to a path of travel through the conduits. The specification further discloses a method for positioning randomly oriented, asymmetrically-shaped articles in the same orientation, the method comprising the steps of: Providing at least first and second oppositely arranged conduits dimensioned to receive the articles therein, each conduit having an inlet end, and the inlet ends of the at least first and second conduits being spaced-apart to define an opening between the conduit inlets for receiving therein, one at a time, a plurality of asymmetrically-shaped articles that are randomly oriented in at least first and second orientations; presenting, one at a time, a plurality of asymmetrically-shaped articles that are randomly oriented in first and second orientations at the opening between the conduit inlets; and creating in both of the at least first and second conduits suction that is sufficient to selectively draw articles oriented in the first orientation from the opening into the inlet end of the at least first conduit, and sufficient to draw articles oriented in the second orientation from the opening into the inlet end of the at least second conduit, such that articles in the at least first and second conduits are all identically oriented relative to a path of travel through the conduits.
