Abstract

An egg lifting device is provided. Such a device includes a body and a securing arrangement extending from the body. The securing arrangement is configured to engage and deflect about an egg such that the egg is seated within the securing arrangement for lifting thereof. A plurality of egg lifting devices is arranged on an egg removal system such that multiple eggs are capable of being removed from an egg flat. Associated systems and methods are also provided.

First claim

That which is claimed:

1. An egg lifting device, comprising:
a body; and
a securing arrangement extending from the body, the securing arrangement being formed of a plurality of resilient deflective members which deflect about an egg and along the contours thereof as the securing arrangement descends onto the egg such that the egg is seated, without additional mechanical actuation of the resilient deflective members, within the securing arrangement, the securing arrangement being configured to vertically align eggs oriented off-axis due to the forces exerted on the egg by the securing arrangement when engaging the egg.

2. An egg lifting device according to claim 1 , wherein the resilient deflective members are arranged and cooperate to form an open-ended arrangement through which the egg is capable of being received.

3. An egg lifting device according to claim 1 , wherein the resilient deflective members are constructed from super-elastic materials or the like.

4. An egg lifting device according to claim 1 , wherein the resilient deflective members are constructed from shape memory materials or the like.

5. An egg lifting device according to claim 1 , wherein the resilient deflective members are constructed from nitinol or the like.

6. An egg lifting device according to claim 1 , further comprising an actuator operably engaged with the body, the actuator being configured to linearly move the body and the securing arrangement extending therefrom.

7. An egg lifting device according to claim 1 , wherein each resilient member comprises a continuous wire loop structure.

8. An egg removal system, comprising:
a frame;
a head operably engaged with the frame and configured to ascend and descend for interacting with a plurality of eggs; and
a plurality of egg lifting devices operably engaged with the head, each egg lifting device having a securing arrangement formed of a plurality of resilient deflective members which deflect about an egg and along the contours thereof as the securing arrangement descends onto the egg such that the egg is seated, without additional mechanical actuation of the resilient deflective members, within the respective lifting device for grasping thereof, the securing arrangement being configured to vertically align eggs oriented off-axis due to the forces exerted on the egg by the securing arrangement when engaging the egg.

9. An egg removal system according to claim 8 , wherein the resilient deflective members are arranged and cooperate to form an open-ended arrangement through which the egg is capable of being received.

10. An egg removal system according to claim 8 , wherein the resilient deflective members are constructed from super-elastic materials or the like.

11. An egg removal system according to claim 8 , wherein the resilient deflective members are constructed from shape memory materials or the like.

12. An egg removal system according to claim 8 , wherein the resilient deflective members are constructed from nitinol or the like.

13. An egg removal system according to claim 8 , further comprising an actuator operably engaged with the body, the actuator being configured to linearly move the body and the securing arrangement extending therefrom.

14. An egg removal system according to claim 8 , wherein each resilient member comprises a continuous wire loop structure.

15. A method of grasping eggs, the method comprising:
engaging an egg lifting device to interact with an egg by contacting a securing arrangement of the egg lifting device with the egg, the securing arrangement having a plurality of resilient deflective members; and
seating the egg, without additional mechanical actuation of the resilient members, within the securing arrangement by deflecting the securing arrangement about the egg along the contours thereof as the securing arrangement engages the egg, the securing arrangement being configured to vertically align eggs oriented off-axis due to the forces exerted on the egg by the securing arrangement when engaging the egg.
