Patent ID: 7779994

Claim:
The method for facilitating the maintenance of a conveyor structure having a long and heavy duty continuous conveyor belt mounted on belt supporting rollers which are mounted on a base, a conveyor drive roller on said base for engaging and cycling said belt, electric drive motor structure for rotating said drive roller, and a belt take-up section positioned intermediate opposite ends of said conveyor structure for supporting a portion of said belt, said method comprising the steps of establishing one or more stationary zero set (counter reset) points on said structure, providing one or more cycle points on said belt, each said cycle point marking a terminus of a designated travel footage of said belt, providing a belt travel footage counter on said conveyor structure for measuring the footage traveled by any of said cycle points on said belt beyond one or more designated zero set points, providing one or more target (work) stations along and in proximity to said belt, providing a belt travel footage reset for resetting said counter to a desired starting belt travel footage reading when a designated cycle point arrives at a designated zero set point, spotting one or more event sites on said belt, a computer for receiving and processing data signals that an event site has been spotted, and providing said computer with belt take-up run footage and belt drift footage data sufficient to determine a power shut off point for said motor whereby a said event site will drift with marked accuracy to a designated target station.
