Speed increasing and accumulating conveyor chain

摘要

The speed increasing and accumulating conveyor chain of the present invention can convey a conveyed object faster than the running speed of the chain, and keep the conveyed object stopped while continuously running the chain itself. The load roller with a larger diameter and the running roller with a smaller diameter are coaxially and rotatably mounted on the connecting pin, which is secured to the link plate, respectively. The frictional material is mounted on the load surface of the load roller, wherein the frictional material provides the load surface of the load roller with a larger frictional force than that of rotatable surface between the load roller and the running roller.
