Double-feed detection
The Duo Reader is used in mail sort operations to detect double-feeds when the de-stacker pulls more than one item from the input hopper into the mail transport. The system is supplied with an industry-standard PC and Windows software and the reader head is focused for life before it leaves the factory. Different shape reader heads are available for integration onto a range of sorting machines.
The Duo Reader speeds up processing and the very low false double and missed double error rates give improved quality of service and fewer sorter jams. The Duo Reader is compact and easy to retrofit, and its integrated design means no customer calibration is necessary. The patented side-view optics allows the Duo Reader to perform well on tabbed and folded mail items.
The image above shows 6 items de stacked at once – without a Duo Reader this group of 6 letters would result in 5 mis-sorted letters, or jam the sorter. Both jams and mis–sorts are reduced by the Duo Reader.
