US 4,199,051 A · Egg transporting system

Abstract

An egg transporting system for receiving eggs from a plurality of egg belt conveyors leading from cages of a poultry installation receives eggs on an input side and transfers them to an opposite side of the system to an accumulation conveyor. The transporting system includes an elevator having a plurality of generally U-shaped egg transporting cradles with asymmetric legs for receiving and cradling eggs at the input side and holding and transferring eggs on the discharge side while providing a smooth transition of the egg from one leg to the other as the eggs are moved from one side of the vertical elevator to the other side. A plurality of the cradles are mounted adjacent one another to cross bars extending between endless loop drives with vertically spaced rows of cradles in abutting contact to present substantially continuous egg receiving openings to the belt conveyors. In one embodiment, the conveyor has an inclined input end to facilitate transfer of eggs into the cradles and improved mounting system for simplifying the attachment of the egg conveyors to the input side of the elevator. In some embodiments, an improved egg counting assembly is mounted to the output side of the elevator for singulating and counting the eggs collected by the system and transferred onto the main conveyor.

Dependent claims

An egg transporting system for receiving and collecting eggs from a plurality of infeed conveyors and discharging the eggs at an output conveyor comprising:

a plurality of egg receiving cradles each of generally U-shaped construction and having a pair of asymmetric legs shaped for alternately receiving eggs from an infeed conveyor and discharging eggs to an output conveyor, said cradles each including a base, a first concavely curved leg joined to said base and cradling an egg against said base when the first leg is in a lower position, and a second leg inclined linearly downwardly and having an upwardly extending tip such that when the second leg is in a lower position an egg will move outwardly from said base and be held by said tip;
and
means for moving said cradles between the infeed conveyor and the output conveyor such that an egg is received by one leg of the cradle and discharged by the other leg, said moving means comprising endless loop drive means and means for supporting said endless loop drive means for movement in generally vertical directions.

An egg elevator comprising:

a pair of horizontally spaced end frames defining an input end and an output end of said elevator;
axle means rotatably supported between said frames in vertically spaced relationship, said axle means including an upper axle near the top of said frames and a pair of horizontally spaced lower axles near the bottom of said frames;
a pair of chains, and sprocket means for coupling said chains around said axles in spaced relationship to one another said lower axles positioned such that the run of chain on the input end of said elevator is inclined toward the output end;
egg conveying cradle means extending between said chains for transporting eggs vertically between said input and output ends of said elevator;
a plurality of mounting bars extending between said chains and wherein said cradle means comprises a plurality of cradles mounted on said bars in horizontally spaced relationship, each of said cradles comprising a generally U-shaped member having a rectangular base and first and second legs, and wherein said first leg is concavely curved and has a depending tip for holding an egg against said base when said first leg is in a lower position in the input end of said elevator, and wherein said second leg is in a lower position and inclined downwardly when in the output end of said elevator, said second leg having a lineally extending portion and including an upwardly extending tip for holding an egg away from said base, said bars spaced and said cradles dimensioned so that said first legs nest with said second legs of vertically adjacent cradles;
egg counting means coupled to said end frames at said output end and comprising:
a plurality of spaced partition walls extending longitudinally along the path of travel of the eggs between said cradle means and spaced to allow an egg to pass between adjacent walls and wherein the upstream ends of adjacent walls are straggered to prevent eggs in adjacent lanes from colliding as they enter the space between said walls;
and
egg sensing means positioned to detect eggs as they pass between said partition walls.
