Abstract

In ovo injection apparatus include an egg carrier configured to hold a plurality of eggs and to provide external access to the eggs, a plurality of injection devices positioned above the carrier, and an egg support assembly positioned beneath the carrier that is configured to support each egg in the carrier during contact therewith by a respective injection device. The egg support assembly includes a frame, a plate having an array of openings attached to the frame, and a plurality of pedestals removably secured within a respective one of the openings. The egg support assembly is operatively associated with the plurality of injection devices such that each pedestal moves upwardly through a respective opening in the carrier to support an egg as a respective injection device makes contact with the egg.

Claims

an egg support assembly positioned beneath the carrier that is configured to support each egg in the carrier during contact therewith by a respective injection device.

2. The apparatus of claim 1, wherein the egg support assembly comprises:

a frame movable between an operative position and a retracted position;

a plate attached to the frame and comprising an array of openings formed therein; and

a plurality of pedestals, each pedestal removably secured within a respective one of the openings, wherein each pedestal comprises a free end portion configured to engage an egg within the carrier when the frame is in the operative position.

3. The apparatus of claim 2, wherein the egg support assembly is operatively associated with the plurality of injection devices such that each pedestal moves upwardly through a respective opening in the carrier to support an egg as a respective injection device makes contact with the egg.

4. The apparatus of claim 1, wherein the egg support assembly is configured to lift each egg from the carrier during contact with each egg by a respective injection device.

5. The apparatus of claim 2, wherein a height of the free end portion of each pedestal relative to the plate is adjustable.

6. The apparatus of claim 5, wherein a height of the free end portion of each pedestal relative to the plate is adjustable via one or more shims disposed between the free end portion and the plate.

7. The apparatus of claim 2, wherein each pedestal includes a proximal end opposite from the free end, and wherein an O-ring is secured to the proximal end that provides a snug, friction fit when the proximal end is disposed within a respective one of the plate openings.

8. The apparatus of claim 2, wherein each pedestal free end has a concave configuration.

9. The apparatus of claim 8, wherein each pedestal free end comprises a wall that is inclined relative to a centerline of the pedestal that is between about twenty five degrees and about fifty five degrees (25°

-55°

).

10. The apparatus of claim 2, wherein the support assembly frame is movable via actuators selected from the group consisting of pneumatic actuators, hydraulic actuators, electronic actuators, and electromagnetic actuators.

11. An in ovo injection apparatus, comprising:

an egg carrier that holds a plurality of eggs and provides external access to the eggs;

a plurality of injection devices positioned above the carrier, wherein each injection device is configured to contact a respective egg in the carrier and deliver a predetermined dosage of a treatment substance into the egg and/or remove material from the egg; and

an egg support assembly positioned beneath the carrier that is configured to support each egg in the carrier and lift each egg upwardly from the carrier during contact therewith by a respective injection device, wherein the egg support assembly comprises;

a frame movable between an operative position and a retracted position;

a plate attached to the frame and comprising an array of openings formed therein; and

a plurality of pedestals, each pedestal removably secured within a respective one of the openings, wherein each pedestal comprises a free end portion configured to engage an egg within the carrier when the frame is in the operative position.

12. The apparatus of claim 11, wherein the egg support assembly is operatively associated with the plurality of injection devices such that each pedestal moves upwardly through a respective opening in the carrier to support an egg as a respective injection device makes contact with the egg.

13. The apparatus of claim 11, wherein a height of the free end portion of each pedestal relative to the plate is adjustable.

14. The apparatus of claim 13, wherein a height of the free end portion of each pedestal relative to the plate is adjustable via one or more shims disposed between the free end portion and the plate.

15. The apparatus of claim 11, wherein each pedestal includes a proximal end opposite from the free end, and wherein an O-ring is secured to the proximal end that provides a snug, friction fit when the proximal end is disposed within a respective one of the plate openings.

16. The apparatus of claim 11, wherein each pedestal free end has a concave configuration.

17. The apparatus of claim 16, wherein each pedestal free end comprises a wall that is inclined relative to a centerline of the pedestal that is between about twenty five degrees and about fifty five degrees (25°

-55°

).

18. The apparatus of claim 11, wherein the support assembly frame is movable via actuators selected from the group consisting of pneumatic actuators, hydraulic actuators, electronic actuators, and electromagnetic actuators.

19. An in ovo injection apparatus, comprising:

an egg carrier that holds a plurality of eggs and provides external access to the eggs;

a plurality of injection devices positioned above the carrier, wherein each injection device is configured to contact a respective egg in the carrier and deliver a predetermined dosage of a treatment substance into the egg and/or remove material from the egg; and

an egg support assembly positioned beneath the carrier that is configured to support each egg in the carrier during contact therewith by a respective injection device, wherein the egg support assembly comprises;

a frame movable between an operative position and a retracted position;

a plate attached to the frame and comprising an array of openings formed therein; and

a plurality of pedestals, each pedestal removably secured within a respective one of the openings, wherein each pedestal comprises a concave free end portion configured to engage an egg within the carrier when the frame is in the operative position, and wherein a height of the free end portion of each pedestal relative to the plate is adjustable.

20. The apparatus of claim 19, wherein the egg support assembly is operatively associated with the plurality of injection devices such that each pedestal moves upwardly through a respective opening in the carrier to support an egg as a respective injection device makes contact with the egg.

21. The apparatus of claim 19, wherein the egg support assembly is configured to lift each egg from the carrier during contact with each egg by a respective injection device.

22. The apparatus of claim 19, wherein a height of the free end portion of each pedestal relative to the plate is adjustable via one or more shims disposed between the free end portion and the plate.
