DEVICE FOR ORIENTATION OF FEED OF STRATIFICATORS Russian patent published in 1996 - IPC

FIELD: mechanical engineering. SUBSTANCE: device for orientation of feed of stratificators has vibrotrough 4 fabricated in the form of three-chamber gripper with two rows of nozzles located above bearing surface 3 and coupled to vacuum outlet of ejector 10 through pneumatic distributor 13. In this case transportation chamber 8 coupled to vacuum outlet of ejector 10 holds part on bearing surface 3 under action of vacuum. Orientation chamber 11 incorporating shutoff unit 15 and sensor 14 of presence of part is coupled in sequence through pneumatic distributor 13 to source of compressed air to drop part and to outlet of ejector 10 to hold it on bearing surface. Chamber 18 for discharge of oriented part has sensor 21 of presence of part, is coupled through pneumatic distributor 20 to vacuum outlet of ejector 10 for holding part on bearing surface 3 on stage of discharge and communicates with atmosphere. Device includes orientation control unit which has sensor 14 of presence of part connected to controlling flip-flop which signal controls vibrohopper 1, vibrodrive 23, drive 17 of shutoff unit 15 and electromagnets of pneumatic distributor 13 on orientation stage through elements of time delay. Control unit of discharge of part has sensor 21 of presence of part connected to controlling flip-flop which signal is transmitted through time-delay element and comparison element to orientation control unit and controls electromagnets of pneumatic distributor 20 on stage of discharge of part. EFFECT: enhanced efficiency and reliability of operations. 2 cl, 3 dwg
