Triple-strand roller chain conveyor with accumulating pallets

摘要

A triple-strand conveyor is provided with guiding rollers on the pallet which coact with a resilient driving roller and a cam plate guide to provide positive control of the pallet during rollover at the conveyor ends from the top to bottom positions and vice versa. The combination of positive drive and resilient control reduces the chain forces associated with rollover and minimizes the need for constant readjustment of the chain tension during operation. The rollers eliminate chain contact during the rollover function thereby eliminating the need for elaborate chain contact and guide devices associated with the prior art.
