Patent number: 4782939Abstract: A can unscrambler system, having a longitudinal can arranger and an unscrambler apparatus, orients randomly oriented unfilled cans having an open end and a closed end such that all of the open ends face the same direction. The longitudinal can arranger arranges randomly oriented cans longitudinally onto a conveyer for transportation to the unscrambler apparatus. The randomly oriented cans are loaded into a collection zone of inclined surfaces, at the bottom of which is the conveyer. A turning belt located adjacent to the conveyer rotates cans that are in a crosswise mode over the conveyer and a brush assembly located downstream of the collection zone allows only longitudinally arranged cans to pass therethrough. The cans are then loaded onto a vacuum conveyer belt at the unscrambler apparatus, where they are conveyed into a sorter mechanism. The sorter mechanism distinguishes between the closed and open ends of the cans and sorts accordingly.Type: GrantFiled: May 29, 1987Date of Patent: November 8, 1988Inventor: W. George Fields

Patent number: 4736831Abstract: The invention pertains to an apparatus that orients unfilled cans having an open end and a closed end such that all of the open ends face the same direction. Unoriented or scrambled cans are first loaded onto a vacuum belt and then conveyed into a sorter mechanism. The ends of the cans are coupled to the vacuum belt by a partial vacuum. The closed ends are distinguished from the open ends by proximity switches which control a solenoid regulated air blast capable of knocking cans having their open ends facing one direction off of the vacuum belt and into a gravity track. The cans are turned to a desired orientation as they descend through the gravity track. Cans on the vacuum belt having their open ends facing in another direction are not subjected to an air blast and are removed from the vacuum belt by another gravity track which turns descending cans into the same desired orientation. The newly oriented cans blend together upon exiting from either gravity track.Type: GrantFiled: December 31, 1985Date of Patent: April 12, 1988Inventor: W. George Fields

Patent number: 4405126Abstract: A gate station incorporates air pressure flows to direct clips in a production stream through the station and to selectively divert defective clips into a separate reject steam. Mounted on a support plate in the station are an upstream manifold, continuously supplied with low pressure air, and a downstream manifold, having a plurality of downwardly directed air ports and selectively supplied with high pressure air. Air flow from the upstream manifold is directed laterally over the upper surface of a clip so as to enable atmospheric pressure to maintain the clip travelling through the gate station in the production stream. If a clip is to be diverted, the downstream manifold is injected with high pressure air causing blasts of high velocity air through the downwardly directed ports. This high velocity air disrupts the flow from the upstream manifold and forces the leading edge of the defective clip downwards, pressing the clip into the reject stream.Type: GrantFiled: January 26, 1981Date of Patent: September 20, 1983Assignee: Beloit CorporationInventors: Kenneth G.

Patent number: 4317656Abstract: The invention contemplates an improved deflection-switch mechanism for a conveyor system which continuously handles a succession of articles, such as like sheets or sheet-like workpieces, on a first conveyor, and which sorts them in alternation to one and then to the other of two further conveyors, whereby in each of the further conveyors the sorted articles are more greatly separated and therefore can be subjected to more effective deceleration prior to their uniformly stacked accumulation. The deflection mechanism of the switch is vacuum-operative upon individual articles, relying upon their spatial distribution in the first conveyor as a basic determinant of whether a particular article is to be automatically deflected or switched, by effectively synchronous commutation, into one or into the other of the two further-conveyor paths.Type: GrantFiled: February 1, 1980Date of Patent: March 2, 1982Assignee: Karl Heinz StieglerInventors: Ehrhart Schulze, Michael Berg
