ABSTRACT:
An acceleration accumulation chain conveyor, having a link/pin chain for driving rollers along rails, the conveyor comprising: support rollers rotatably loosely fitted over the pins, each support roller having a larger diameter portion with a rim for engaging conveyed articles and side faces, and annular bosses of smaller diameter projecting axially from the side faces, the bosses having inner peripheral surfaces for frictionally engaging the pins and outer peripheral surfaces; and, chain rollers rotatably loosely fitted on the bosses, the chain rollers having inner peripheral surfaces for frictionally engaging the outer peripheral surfaces of the bosses, outer peripheral surfaces for engaging the rails and side faces for frictionally engaging the side faces of the support rollers, one of the inner and outer peripheral surfaces of the chain rollers being tapered to direct a component of force urging the chain rollers inwardly to enable frictional engagement between the respective side faces and the outer peripheral surfaces of the bosses being shaped to conform to the inner peripheral surfaces of the chain rollers, whereby the frictional engagement between the chain and support rollers is substantially increased.
