Abstract:
A vibratory conveyor apparatus, comprising:a frame;a drive assembly borne by the frame for imparting vibratory motion to the frame;a first resilient member comprised of a first leaf spring mounted on the frame;a bed mounted on the first resilient member, the first resilient member transmitting the vibratory motion from the frame to the bed and wherein the vibratory motion of the bed comprises a reciprocating movement along a given range of motion, and wherein the range of motion is defined between a first forwardmost position, and a second, rearwardmost position;an amplitude compensator comprising a second resilient member mounted on the frame to substantially impede the bed from traveling outside a given range of motion as the bed moves in response to the vibratory motion, by transmitting a given force between the bed and the frame; and wherein the second resilient member is comprised of a second leaf spring; andwherein the given force is produced when the bed deforms the second resilient member, and wherein the deformation occurs as the bed travels outside the given range of motion; and wherein movement of the bed beyond the given range of motion causes the bed to impinge against the second resilient member, thus deforming the second resilient member.
