Abstract
A bulk material handling conveyor system having a set of buckets carried in a continuous manner from an infeed zone where the buckets are filled with product by way of a metering vibratory feeder to an unloading zone and back to the infeed zone. The buckets may be selectively at least partially emptied in the unloading zone. The conveyor system also includes a proximity trigger for sensing the bucket at the infeed zone adjacent the metering vibratory feeder, a processing unit electrically connected to the proximity trigger for receiving and storing the output of the proximity trigger, a fill determining sensor mounted proximate the buckets between the infeed and unloading zones, the fill determining sensor being connected to the processing unit so that the processor receives and stores the fill status of the buckets upstream of the infeed zone, and a feeder control for cycling the metering vibratory feeder on and off responsive to signals from the processor, the processor signaling the feeder control to cycle on when a bucket is sensed by the fill determining sensor to be less than full.
