Vibratory apparatus

Claim 2

Vibratory apparatus comprising a frame, a container defining a chamber adapted to receive a load of media and parts to be vibrated, spring means mounted on said frame and supporting said container for vibration, power-operated means cooperating with said spring means for vibrating said container with sufficient force to effect orbital movement of the load in a path which causes movement of the parts toward the upper surface of the load, conveyor means positioned adjacent said chamber and extending to a discharge station, magnetic means associated with said conveyor means and adapted to attract parts from the media within said chamber to said conveyor means, and means for releasing parts at said discharge station from the attraction of said magnetic means.

Claim 3

Vibratory apparatus as defined in claim 1 wherein said container has an open top, said spring means and said power-operated means cooperate to effect vibration of said container at a greater amplitude on one side of the center of said container than on the other side to aid the orbital movement of the load, and said conveyor means and said magnetic means extend across said open top of said container.

Claim 4

Vibratory apparatus as defined in claim 1 including directing means disposed within said chamber to assure orbital movement of the parts upwardly within said chamber and within the field of said magnetic means.

Claim 5

Vibratory apparatus as defined in claim 3 including means connecting said directing means within said chamber to said conveyor means, and means supporting the assembly of said conveyor means, said magnetic means and said directing means for movement between a parts-removing position and an upwardly retracted position.

Claim 6

Vibratory apparatus as defined in claim 1 wherein said conveyor means includes an endless belt, a set of rollers supporting said belt, and said belt has a lower run extending adjacent an open top of said container.

Claim 7

Vibratory apparatus as defined in claim 1 wherein said magnetic means comprise a permanent magnet positioned adjacent the path of said belt.

Claim 8

Vibratory apparatus as defined in claim 1 including means for moving said conveyor means and said magnetic means between a parts-removing position adjacent said chamber and a retracted position spaced from said chamber.

Claim 9

Vibratory apparatus as defined in claim 1 including means supporting said conveyor means and said magnetic means for generally horizontal movement as a unit to provide for removing the parts from a plurality of said vibratory containers with one said unit.

Claim 10

Vibratory apparatus comprising a frame, a container defining an open top chamber adapted to receive a load of media and parts to be vibrated, a plurality of spring beams mounted on said frame and supporting said container for oscillatory movement on a predetermined effective axis offset laterally in relation to a generally vertical plane extending through the center of said container, said spring beams being effective to provide said container and the load therein with a resonant frequency corresponding generally to a predetermined frequency, power operated means for oscillating said container at substantially said predetermined frequency to cause orbital movement of the load within said chamber, an endless conveyor belt, roller means supporting said belt within a lower run positioned adjacent said open top of said chamber and extending to a discharge station, a permanent magnet positioned within said conveyor and adapted to attract parts from the media within said chamber to said lower run of said conveyor, means for releasing parts at said discharge station from said belt, and means supporting the assembly of said conveyor belt and said magnet for movement between said position adjacent saId chamber and a retracted position spaced from said container.

Claim 11

Vibratory apparatus comprising a frame, a container defining an open top chamber adapted to receive a load of media and parts to be vibrated, a plurality of spring beams mounted on said frame and supporting said container for oscillatory movement on a predetermined effective axis offset laterally in relation to a generally vertical plane extending through the center of said container, said spring beams being effective to provide said container and the load therein with a resonant frequency corresponding generally to a predetermined frequency, power operated means for oscillating said container at substantially said predetermined frequency to cause orbital movement of the load within said chamber, an endless conveyor belt, roller means supporting said belt within a lower run positioned adjacent said open top of said chamber and extending to a discharge station, a permanent magnet positioned within said conveyor and adapted to attract parts from the media within said chamber to said lower run of said conveyor, means for releasing parts at said discharge station from said belt, and means supporting the assembly of said conveyor belt and said magnet for movement between said position adjacent saId chamber and a retracted position spaced from said container.
