Apparatus for selectively processing eggs, and associated method

1. An egg injection apparatus, comprising:

an egg processing head;

a plurality of injection devices operably engaged with the egg processing head so as to be capable of moving in a substantially vertical direction thereby, each injection device having an end configured to contact an avian egg and further having at least one of a needle and a punch configured to pierce the avian egg; and

wherein the end of each injection device is capable of selectably engaging the egg such that the injection devices are selectively held in one of a non-contact position and a contact position during an injection sequence such that a first subset of the ends of the injection devices is in the non-contact position while simultaneously during the injection sequence having a second subset of the ends of the injection devices in the contact position contacting the respective eggs, the non-contact position being at a vertical height above the contact position such that the ends of the first subset of injection devices are selectively held above the ends of the second subset of injection devices.

2. An egg injection apparatus according to claim 1 , wherein the egg processing head has a clamp plate defining a plurality of holes for receiving the injection devices, the clamp plate being configured to selectively secure each injection device in one of the non-contact position and the contact position.

3. An egg injection apparatus according to claim 2 , further comprising a plurality of annular locking devices seated within the holes of the clamp plate, each annular locking device defining an annular opening through which the injection device moves substantially vertically, and each annular locking device being configured to individually secure a respective injection device in one of the non-contact position and the contact position during the injection sequence.

4. An egg injection apparatus according to claim 3 , wherein each annular locking device comprises a pneumatic valve in communication with a positive air supply system, the pneumatic valve being configured to facilitate locking of the injection devices pneumatically.

5. An egg injection apparatus according to claim 4 , wherein each locking device comprises a rigid body member cooperating with a bladder to form an air channel such that the bladder is capable of being pneumatically inflated for securing the annular locking devices in the non-contact and contact positions.

6. An egg injection apparatus according to claim 3 , wherein each annular locking device comprises an inflatable member capable of being pneumatically inflated for securing the annular locking devices in the non-contact and contact positions.

7. An egg injection apparatus according to claim 1 , further comprising an egg classifier system configured to classify an avian egg as one of engageable and non-engageable, the egg classifier system being in one of direct and indirect communication with the injection devices so as to instruct positioning of each injection device in one of the non-contact and contact positions during the injection sequence.

8. An egg injection apparatus according to claim 1 , further comprising a conveyor assembly configured to automatically convey avian eggs to the egg processing head for injection thereof.

9. A method of selectively injecting avian eggs, the method comprising:

providing a plurality of injection devices being in alignment with a plurality of avian eggs, each injection device having an end configured to contact a respective avian egg and further having at least one of a needle and a punch configured to pierce the avian egg;

securing a first subset of the injection devices in a non-contact position at a first height with respect to the eggs such that the ends of the injection devices do not contact the respective avian eggs;

descending a second subset of the injection devices lower than the first height so as to engage the ends thereof with respective avian eggs aligned therewith;

securing the ends of the second subset of injection devices in a contact position with respect to the corresponding eggs; and

injecting a treatment substance into the avian eggs engaged with the ends of the second subset of injection devices, while simultaneously the ends of the first subset of injection devices are spaced-apart from the eggs in the non-contact position.

10. A method according to claim 9 , wherein the steps of securing a first and second subset of the injection devices further comprises selectively securing the first and second subsets with a clamp plate configured to selectively hold each injection device in one of the non-contact position and the contact position, the clamp plate defining a plurality of holes for receiving the injection devices.

11. A method according to claim 10 , wherein selectively securing the first and second subsets further comprises selectively securing the first and second subsets with a plurality of annular locking devices seated within the holes of the clamp plate, each annular locking device defining an annular opening through which the respective injection device moves substantially vertically, and each annular locking device being configured to individually secure a respective injection device in one of the non-contact position and the contact position.

12. A method according to claim 11 , wherein selectively securing the first and second subsets with a plurality of annular locking devices further comprises pneumatically inflating an annular resilient member of each locking device so as to selectively secure the annular locking devices in one of the non-contact and contact positions.

13. A method according to claim 12 , wherein pneumatically inflating a bladder of each locking device further comprises pressurizing an air channel formed by cooperation of the bladder with a rigid body member.

14. A method according to claim 11 , further comprising the step of classifying each avian egg as one of engageable and non-engageable, and further comprising the step of communicating the classification of each avian egg to the respective annular locking device so as to instruct positioning of each injection device in one of the non-contact and contact positions.

15. A method according to claim 9 , further comprising the step of automatically conveying the avian eggs for alignment with the injection devices.
