Abstract
A vertical conveyor for conveying a stream of closely spaced articles along a conveyor path includes at least one pair of roller chain assemblies that face the conveyor path. Each chain assembly includes a roller chain carrying grippers that extend into the conveyor path to securely hold articles between them. Bearings engage the roller chain to limit chain deflection under load to assure reliable conveyance of the articles.
