This disclosure relates to an automatic conveyor system having a plurality of sensors to detect the positions of the conveyor carriers so that the difference between a computed carrier position and its actual position will be less than the maximum tolerable error due to wear, stretch or slack in the conveyor belt or chain. At the time an article or parcel is placed in the conveyor system, its carrier designation and position of the destined receiving bin are stored in a memory. During each incremental time period, the contents of the memory are scanned and compared with counters associated with each position sensor. When a comparison is achieved, a signal is sent to the appropriate receiving bin to actuate the corresponding carrier to unload its contents.
