Delta's Area Sensor AS-B/E Series Communication Type are installed on the infeed conveyor to measure parcel size/shape on the belt by calculating blocked light beams, uploading the data to the control system, and generating the cross-section area and center position of parcels.
After obtaining the parcel data, the sorter system adjusts the belt speed to ensure parcels are delivered to the center of the sorting tray without dropping, achieving efficient sorting and dispatch of goods.
