Article-holding cup and scale for apparatus that sorts articles by weight

An article weighing and sorting apparatus, comprising:

• a pair of spaced-apart, parallel continuous conveyors which pass through a loading zone, a weighing zone, and a discharge zone;
• a plurality of cups pivotally attached to each of said conveyors for selective pivoting in said discharge zone toward the other conveyor and comprising a cavity for receiving an article while said cup is in said loading zone, each cup comprising:
• a first support surface and a second support surface for supporting said cup on a scale in said weighing zone, said first support surface disposed at a free end of an arm extending outwardly and downwardly from a side of said cup, said second support surface disposed on said lower side of a pin extending laterally from an opposite side of said cup, said first support surface being lower than said second support surface;
• means for supporting said cup solely on said support surfaces independently of the conveyor associated with the cup, during the weighing of said cup;
• means for pivoting a selected cup in a discharge zone to discharge said article from said cup;
• means for receiving a discharged article;
• a plurality of rods disposed normal between said two conveyors, each rod connected at its respective longitudinal ends to one of said carriers, said support surface of said first member being in a plane vertically lower than said rods;
• and
• a fabric flap attached to each rod for gently communicating an article pivoted from a selected cup to said receiving means.

An article weighing and sorting apparatus, comprising:

• a continuous conveyor which passes through a loading zone, a weighing zone having a weighing platform, and a discharge zone;
• a plurality of cups each for receiving an article while in said loading zone, each cup attached to said conveyor for selective pivotal movement in said discharge zone about an axis generally parallel to said direction of movement of said conveyor, each cup comprising a first support surface and a second support surface for supporting said cup on a scale in said weighing zone, said first support surface being disposed lower from said cup than said second support surface;
• a first rail connected to the weighing platform and aligned with said first support surface;
• a second rail connected to the weighing platform and aligned with said second support surface;
• the first rail being lower than the second rail so that the cup is horizontal on the weighing platform as the cup passes through the weighing zone;
• means for pivoting a selected cup in a discharge zone to discharge said article from said cup;
• means for receiving a discharged article;
• and
• said first support surface is at a free end of an arm extending outwardly and downwardly from a side of said cup.

An article weighing and sorting apparatus, comprising:

• a continuous conveyor which passes through a loading zone, a weighing zone having a weighing platform, and a discharge zone;
• a plurality of cups each for receiving an article while in said loading zone, each cup attached to said conveyor for selective pivotal movement in said discharge zone about an axis generally parallel to said direction of movement of said conveyor, each cup comprising a first support surface and a second support surface for supporting said cup on a scale in said weighing zone, said first support surface being disposed lower from said cup than said second support surface;
• a first rail connected to the weighing platform and aligned with said first support surface;
• a second rail connected to the weighing platform and aligned with said second support surface;
• the first rail being lower than the second rail so that the cup is horizontal on the weighing platform as the cup passes through the weighing zone;
• means for pivoting a selected cup in a discharge zone to discharge said article from said cup;
• means for receiving a discharged article;
• a second continuous conveyor parallel to and spaced apart from said first conveyor and including a plurality of said cups;
• the first support surfaces of the cups on the first conveyor faces the same surfaces of the cups on the second conveyor;
• a plurality of rods connected to and extending between said two conveyors;
• and
• a fabric flap attached to each said rod for gently transferring an article discharged from a selected one of said cups to said receiving means,
• wherein said first support surfaces extend downwardly below the plane in which said rods travel, so that the rods do not interfere with the first rail as the rods pass through the weighing zone.
