After each induction station of the slide tray sorter there will be a bar with photo-eyes looking through the hole pattern to detect if an item was inducted. Also before each induction zone a pre-induction pe bar will be installed to check if a tray is empty before the induction zone. The hole pattern is designed so non-transparent products of 70 mm x 70 mm (length x width) will always be detected. Products should meet both the minimum length and width of 70 mm for guaranteed detection.
Small item detection
With our special small item detection system we place labels with barcodes on the bottom of the trays. Each item detection unit is a scanner reading the barcode. If one of the barcodes is not read we know there is an item in the tray. Wit this system we can detect items of 50 x 20 mm footprint.
