DETERMINATION AND CORRECTION OF CONVEYOR BELT SPEED/LOCATION

摘要

Sprockets (22) and (42) are engaged with a conveyor belt (18) itself or a chain (28) coupled to the belt. An encoder is used to determine the differential of the rotation of the sprockets. From that information, the instantaneous pitch of the conveyor belt located between the first and second rotational axes can be determined, and from that information the speed of the belt can be determined. This information can be used to control work tools or other devices that act on work products being carried by the conveyor belt.
