Magnetic disc orientor for aerosol valves

Claim 1

A device for the withdrawal from a trough of aerosol container valves provided with drawing tube and orderly conveyance thereof to a collecting guide, comprising a fixed frame, a disc mounted on said frame and rotatable about a substantially horizontal axis and having a plurality of holes circumferentially arranged and spaced apart from one another, a trough located in front of said disc, at the lower end of said disc forming a sidewall of the trough, the bottom wall of which is slanting to the disc, means for rotatably driving the disc, a plurality of permanent magnets accommodated one in each of said holes wherein said magnets are movable and have a portion thereof projecting from the rear side of a disc, a plurality of springs, each of which having one end thereof abutting on the disc and the other end thereof abutting on one of said magnets urging it to the rear side of said disc, a fixed cam positioned rearwardly of the disc at the holes therein and extending at least at a portion of said through where the cam surface is moved close to the adjacent disc surface and abuts on the portion projecting rearwardly of the disc for those magnets positioned in this portion of the trough pressing said springs and holding the magnets partially projecting from the front surface of the disc, a rotatable member rotatably driven by the disc adjacent the periphery of which it is mounted on a sHaft fast with said frame, this member having at least one elongated arm member forwardly projecting of the disc and extending between and beyond the holes of said disc, only one arm member at a time being positioned between two adjoining holes without overlying thereon, a shaped fixed guide being also provided for holding and allowing the movement thereon for said valves provided with drawing tube, one end of said guide having a free mouth or inlet in proximity of which said guide is positioned just in front of the disc and is substantially tangent to the circumference for said holes of the disc.

Claim 2

A device for the withdrawal from a trough of aerosol container valves provided with drawing tube and orderly conveyance thereof to a collecting guide, comprising a fixed frame, a disc mounted on said frame and rotatable about a substantially horizontal axis and having a plurality of holes circumferentially arranged and spaced apart from one another, a trough located in front of said disc, at the lower end of said disc forming a sidewall of the trough, the bottom wall of which is slanting to the disc, means for rotatably driving the disc, a plurality of permanent magnets accommodated one in each of said holes wherein said magnets are movable and have a portion thereof projecting from the rear side of a disc, a plurality of springs, each of which having one end thereof abutting on the disc and the other end thereof abutting on one of said magnets urging it to the rear side of said disc, a fixed cam positioned rearwardly of the disc at the holes therein and extending at least at a portion of said through where the cam surface is moved close to the adjacent disc surface and abuts on the portion projecting rearwardly of the disc for those magnets positioned in this portion of the trough pressing said springs and holding the magnets partially projecting from the front surface of the disc, a rotatable member rotatably driven by the disc adjacent the periphery of which it is mounted on a sHaft fast with said frame, this member having at least one elongated arm member forwardly projecting of the disc and extending between and beyond the holes of said disc, only one arm member at a time being positioned between two adjoining holes without overlying thereon, a shaped fixed guide being also provided for holding and allowing the movement thereon for said valves provided with drawing tube, one end of said guide having a free mouth or inlet in proximity of which said guide is positioned just in front of the disc and is substantially tangent to the circumference for said holes of the disc.
