DEVICE FOR CHECKING AND MULTIPLE RANGE SORTING OUT OF FLAT ARTICLES Russian patent published in 1997 - IPC

FIELD: mechanical engineering; checking and sorting out of miniature and small sized flat articles. SUBSTANCE: device has article feed unit formed by upper cover 4 and base 1 with ports 6 and outlet troughs 7, articles passage and location pickups 31 and 32, linear dimensions pickups, and pneumatic converters of all dimensions pickups installed in upper cover of transporting trough 5 provided with inclined nozzles and pushers-nozzles 16 and 17 which are adjustable in height. Outputs of all fluidal threshold elements are connected to control inputs of corresponding flip-flops connected with inputs of amplifier unit. Outputs of additional article location pickups are connected to inputs of control unit 20 whose output is connected to inputs of flip-flops 35. Device has two shaped plates installed for relative displacement between upper cover 4 and base 1. Inclined nozzles are installed in lower wall of outlet troughs 7 at acute angle relative to direction of displacement of articles. EFFECT: enlarged operating capabilities. 5 dwg
