Abstract

An egg removal apparatus includes a frame-and a manifold removably secured to the frame. The frame is movable from a first location overlying an egg flat to a second location overlying an area adjacent the egg flat. When the frame is in the first location, eggs from an egg flat are picked up under vacuum via a plurality of flexible cups. When the frame is in the second position, the eggs are released from the plurality of flexible cups. The removable manifold can be quickly and easily removed from a supporting frame and cleaned as a unit.

Claims

1. An apparatus for removing eggs from an egg flat comprising:

a frame positioned above the egg flat;

a manifold removably secured to the frame, the manifold comprising opposite upper and lower surfaces, first and second sets of internal passageways, and a plurality of plunger bores extending from the upper surface to the lower surface, wherein each plunger bore is in communication with one of the first and second internal passageways;

a plurality of elongated plungers, each having opposite first and second ends and an axially-extending internal bore that terminates at a first port in the plunger first end and at an opposite second port in a medial portion of the plunger between the first and second ends, wherein each plunger is supported for reciprocal movement between first and second positions in a respective plunger bore, wherein each plunger second port is in communication with an internal passageway of the first set of internal passageways when the plunger is in the first position, and wherein the plunger second port is in communication with an internal passageway of the second set of internal passageways when the plunger is moved to the second position;

a plurality of flexible cups, each secured to a respective plunger first end and each in communication with an internal bore of the respective plunger, wherein each flexible cup is configured to engage and retain an egg in seated relation therewith when a plunger secured thereto is moved to the second position so that vacuum can be provided within the flexible cup via the plunger internal bore and wherein each flexible cup is configured to release a respective egg when a plunger secured thereto is moved to the first position.

2. An apparatus according to claim 1 further comprising means for moving each plunger from the first position to the second position.

3. An apparatus according to claim 1 further comprising means for creating a vacuum within the second set of internal passageways.

4. An apparatus according to claim 3 wherein the second set of internal passageways terminate at a first aperture in the manifold and wherein the means for creating a vacuum within the internal passageways comprises means for applying vacuum to the second set of internal passageways via the first aperture.

5. An apparatus according to claim 1 further comprising means for introducing positive air pressure within the first set of internal passageways to facilitate releasing an egg from a flexible cup when a plunger secured thereto is moved to the first position.

6. An apparatus according to claim 5 wherein the first set of internal passageways terminate at a second aperture in the manifold and wherein the means for introducing positive air pressure within the first set of internal passageways comprises means for introducing positive air pressure within the first set of internal passageways via the second aperture.

7. An apparatus according to claim 5 further comprising means for automatically returning a respective plunger from the second position to the first position upon removal of the downwardly directed force.

8. An apparatus according to claim 1 wherein the means for moving a respective plunger from the first position to the second position comprises means for applying a downwardly directed force to the plunger second end so as to move the plunger downward within a respective plunger bore.
