Abstract

An egg transfer apparatus is configured to distribute eggs substantially evenly with reduced breakage on a moving conveyor. The egg transfer apparatus includes a conveyor having opposite first and second ends, a pair of elongated members that extend along the direction of travel of the conveyor between the conveyor first and second ends, and a plurality of spaced-apart, diverging guides positioned downstream from the elongated members. Each elongated member includes opposite first and second end portions. The first end portions of the elongated members are in generally parallel, spaced-apart relationship, and the second end portions have an arcuate configuration and converge to define an opening therebetween through which eggs on the conveyor are conveyed. The diverging guides are positioned downstream from the opening and cause the eggs passing through the opening to be generally evenly distributed at the conveyor second end.

8. The egg transfer apparatus of claim 1, wherein each guide has a height of between about 2 inches and about 3 inches and a length of between about 6 inches and about 8 inches.

9. The egg transfer apparatus of claim 1, wherein the opening is between about 17 inches and about 21 inches.

10. An egg handling system, comprising:

an egg positioning apparatus that positions eggs in a predetermined orientation, wherein the egg positioning apparatus comprises a plurality of receptacles for receiving the eggs and a plurality of chutes for directing eggs in single-file order to the receptacles; and

an egg transfer apparatus operably associated with the egg positioning apparatus, the egg transfer apparatus comprising;

an endless conveyor having opposite first and second ends, wherein the conveyor conveys eggs disposed thereon from the first end to the second end;

a pair of elongated members extending along the direction of travel of the conveyor between the conveyor first and second ends in adjacent, spaced-apart relationship, wherein each member includes opposite first and second end portions, and wherein the second end portions of the elongated members converge to define an opening therebetween through which eggs on the conveyor are conveyed; and

a plurality of spaced-apart, diverging guides positioned downstream from the opening, wherein eggs conveyed through the opening and diverging guides are caused to be generally evenly distributed at the conveyor second end adjacent the chutes.

11. The egg handling system of claim 10, wherein the elongated members and diverging guides oscillate together along a direction of movement of the conveyor.

12. The egg handling system of claim 10, wherein the second end portions of the elongated members have an arcuate configuration.

13. The egg handling system of claim 10, wherein the first end portions of the elongated members are in generally parallel, spaced-apart relationship.

14. The egg handling system of claim 10, wherein each guide extends along a respective direction, and wherein the respective directions converge at a location upstream from the opening.

15. The egg handling system of claim 10, wherein the guides have a substantially planar configuration.

16. The egg handling system of claim 10, further comprising a panel overlying the conveyor in face-to-face, spaced-apart relationship therewith, and wherein the guides are secured to the panel and extend towards the conveyor from the panel.

17. The egg handling system of claim 10, wherein each guide has opposite first and second ends, wherein the first ends of adjacent guides are spaced apart between about 2 inches and about 4 inches, and wherein the second ends of adjacent guides are spaced apart between about 4 inches and about 6 inches.
