Abstract
A conveyor control system and method for positioning an object at a desired location along a conveyor. The system and method detects objects moving along a conveyor and controls deceleration of the conveyor in order to position the object as desired. The system and method account for varying distances between objects on the conveyor and varying distances between objects and the desired position by calculating a delay period during which the conveyor is allowed to continue to accelerate before it is decelerated. At the end of the deceleration, the object reaches the desired location. The delay period is calculated by comparing the known acceleration and deceleration rates of the conveyor with the measured acceleration time of the conveyor from a starting time to the time the object is detected. The system and method are useful for stopping an object such as a package at the exit end of the conveyor.
