Patent ID: 7810632

Claim:
A vibratory conveying apparatus comprising: a conveying chute connected to a driving source, a leaf spring reciprocatingly vibrated by said driving source and a first conveying surface connected to said leaf spring, said first conveying surface being adapted to linearly convey parts by reciprocating vibration from a first end to a second end of said first conveying surface while aligning a posture of the parts or sorting the parts; a linear return chute having a second conveying surface, said second conveying surface being adapted to return parts dropped from said conveying chute during the posture aligning or sorting process performed on said conveying chute, said second conveying surface being adapted to return said parts to said first end of said conveying chute; a deflectable motion transmitting structure connecting said first conveying surface of said conveying chute to said return chute, said deflectable motion transmitting structure being adapted to transmit vibration applied to said first conveying surface of said conveying chute to said return chute to reciprocally vibrate said second conveying surface as well as to absorb a displacement caused by an amplitude of the reciprocal vibration; said driving source comprising a piezo-electric element or an alternating electric magnet wherein the driving source itself vibrates reciprocally to produce reciprocating vibration.
