Patent ID: 8050795

Claim:
A drive control system for a conveyor comprising: a conveyor device that is operable to move material via a flexible member along a single conveyor that is propelled by two or more motors in a load sharing drive control application; a computer for processing data; a dynamic mathematic model calculation program executed by said computer, said program being operable to continuously evaluate the torque requirements of the system and produce a signal responsive of actual torque demands; a PLC operable to monitor and control all input and output devices associated with the conveyor; a motor controller in communication with the PLC, said controller is operable to receive input data from the PLC and deliver torque and speed power outputs to a motor; a motor operable to receive the torque and speed power outputs and provide power to a primary moving element of said system; and a plurality of primary zones positioned about the conveyor, each said zone including a counting device near proximal ends of said zones for counting a number of segments of said flexible member.
