Abstract: An article-unloading apparatus comprising a bin assembly including a bag inside a bin. The bin assembly is raised and lowered by a lift and tilted, when raised, to dump articles onto a decline conveyor, such as a ramp. A winch attached to the bag moves the bottom of the bag through the bin to help push articles from the tilted bin assembly. A camera takes a video image of the articles entering the ramp to detect clumps. Stops on the ramp are selectively actuated to block the bottom-most articles in a clump to help separate articles.

Abstract: A conveyor employs an infeed assembly and outfeed assembly, each comprising a nosebar assembly that may be mounted to a conveyor frame to transition a conveyor belt between a returnway and a carryway, a belt guiding roller, such as a sprocket or brake, a position limiter for ensuring proper engagement between the belt guiding roller and the conveyor belt and a connecting plate that ensures proper placement of the position limiter relative to the guide roller. The infeed assembly and outfeed assembly components may be easily moved into engagement and out of engagement to facilitate replacement, cleaning or maintenance.

Abstract: A grid sorter for discharging articles received from many inputs to selected discharge destinations. The grid sorter comprises a rectangular grid of parallel conveyor lines. Each line has a series of bidirectional conveyors fed articles by infeed conveyors at each end of the line. Omnidirectional-roller sorters, at the intersections of the conveyor lines, can pass articles received from one line in multiple directions: along that same line; in either direction to an intersecting line; or obliquely to a selected discharge between lines. Omnidirectional rollers in the omnidirectional-roller sorters are controlled by a controller to push articles in selected directions to predetermined discharge destinations.

Abstract: A conveying system employs independently controlled flights. The flights are controlled separately from a conveying surface using a linear transport system. The linear transport system allow the position of the flights to be controlled based on a parameter, such as the length of a conveyed object. The flights are pivotally mounted to a mover of the linear transport system and can pivot relative to the conveying surface to allow the flights to fit in a space between an end of carryway and a receptacle.

Abstract: A cleanable frame and a method for making a cleanable frame having a simplified frame design. A hygienic conveyor frame assembly comprises a plurality of hollow tubular sections joined together to form an evacuated, sealed conveyor frame support structure that functions as a sterilization zone. An integral carryway is placed on the support structure. Lifters coupled to the conveyor frame can lift the carryway and conveyor belt for cleaning. Infeed and outfeed assemblies are also movable between operating and cleaning positions. A sensor can monitor the conditions of the frame interior to ensure that the vacuum is maintained and initiate a corrective action if the vacuum seal is breached.

Abstract: An integral weighing and sorting system that weighs articles on a roller belt and selectively actuates or deactuates belt rollers to divert selected articles. After an article is weighed on the roller belt, its weight is compared to a predetermined weight range. Out-of-range articles are directed to exit the belt via a different route from that of in-range articles by actuating the rollers to rotate in a direction transverse to the travel direction in a roller-actuation zone.

Abstract: An omnidirectional anemometer and a method for using such an anemometer to measure the airflow along a conveying path, such as a helical path through a processing chamber. The anemometer is a low-profile, omnidirectional, three-axis anemometer with minimal airflow-occluding structure. Because of its low profile, the anemometer can fit in spiral conveyors with a short tier pitch.

Abstract: A conveyor system for conveying electrically conductive articles such as aluminum bottles or cans. The conveyor system comprises a plurality of coils below the top surface of an electromagnetic conveyor at a junction between an infeed conveyor and a discharge conveyor. The coils propagate electromagnetic flux waves that induce currents in the electrically conductive articles that force the articles to follow a conveying path from the infeed to the discharge conveyor. Dead spots on the electromagnetic conveyor can be eliminated by adjusting the coil drive waveforms. And a long electromagnetic conveyor driven by a train of narrow pulses is used to singulate electrically conductive articles.
