Abstract
A vibratory apparatus is provided to dislodge and separate foreign matter from castings. A curved, bottom, supporting surface for the castings is inclined downwardly towards an outlet. Vibration imparting apparatus cause individual castings to travel up the curved portion and tumble over themselves as they simultaneously advance towards the outlet. Foreign matter, separated from the castings, is diverted away from the hopper as the castings progress continuously between the inlet and the outlet in a helical path.
Claims8
A vibratory apparatus for separating foreign matter from castings comprising:
- a hopper having an inlet for admitting the castings to the hopper, an outlet through which castings are discharged from the hopper, a longitudinal axis and a bottom surface for supporting the castings,
- said hopper inlet and hopper outlet being spaced from each other in a first direction,
- means for supporting the hopper with the bottom surface inclined a few degrees downwardly from the inlet toward the outlet;
- vibration imparting means comprising at least one motor having a shaft lying in a plane extending transverse to said first direction and carrying at least one eccentric weight thereon,
- resilient means mounted between said vibration imparting means and said hopper for resiliently mounting said vibration imparting means to one quadrant of said hopper and for directing vibratory forces into one diametrically opposite quadrant and into one other quadrant on the same level as said opposite quadrant of said hopper for conveying castings in said first direction from the inlet to the outlet of the hopper as the castings are tumbled in a path transverse to said first direction, and
- means on the hopper between the hopper inlet and hopper outlet for directing foreign matter separated from the castings in the hopper away from the hopper upstream from where the castings are discharged through the outlet,
- whereby said castings can be continuously directed between the hopper inlet and outlet and foreign matter can be continuously separated from the castings and directed away from the hopper.
A vibratory apparatus for separating foreign matter from castings comprising:
- a hopper having a bottom surface for supporting the castings, an inlet for admitting castings to the hopper and an outlet for discharging castings from the hopper and spaced from the inlet in a first direction,
- said hopper having a U-shape in cross-section transverse to said first direction with one leg of the U extending upwardly at a greater angle to horizontal than the other leg of the U,
- said legs each having surfaces for confining the castings in conjunction with the bottom hopper surface;
- means supporting the hopper so that the bottom surface is inclined downwardly from the inlet towards the outlet;
- vibration imparting means comprising at least one motor having a shaft lying in a plane extending transverse to said first direction and carrying at least one eccentric weight thereon,
- resilient means mounted between said vibration imparting means and said hopper for resiliently mounting said vibration imparting means to an upper quadrant of said hopper and for directing vibratory forces into both lower quadrants of said hopper for conveying castings in said first direction from the inlet to the outlet of the hopper as the castings are tumbled in a path transverse to said first direction, and
- means for directing foreign matter separated from the castings in the hopper away from the hopper,
- whereby said castings can be continuously directed between the hopper inlet and outlet and foreign matter can be continuously separated from the castings and directed away from the hopper.
