Abstract: An automatic egg injection machine comprises a separate injector support grid and injector locking device. The injector locking device is attached to the body of the egg injection machine to prevent motion during the vaccination process. Individual air tubes are inserted into slots in the injector locking device, and are inflated with compressed air to lock the injectors in place during the injection process, thereby minimizing the possibility of injector movement. Both the injector support grid and injector locking device can be exchanged for other components with different egg configurations so that one egg injection machine can be used for more than one sized incubator egg flat.

Abstract: An automatic vaccinator of eggs, consisting of a system for applying vaccine with a vaccine chamber in which vaccine bags are hung and with an air bag that, when expanded, forces the vaccine from the bags and through tubing to a distribution manifold and the injectors, so that the vaccine is delivered to the eggs, is disclosed. A pressure sensor is installed in the distribution manifold and connected to a regulator, measuring the pressure in the distribution manifold at the point farthest from the vaccine chamber and controlling the pressure in the air bag to maintain a uniform quantity of vaccine being injected into the eggs and turning off the vaccinator if the pressure falls below a critical level, signaling that the vaccine bags are empty. The mechanical unit includes a system to support, align and secure the injectors over the egg tray, composed of two plates that work independently, a support plate and an alignment plate.

Abstract: The invention relates to a system of automatic vaccination of eggs, developed for the purpose of vaccinating large quantities of fertile eggs in order to reduce the costs and labor involved, reduce embryonic mortality by increasing protection from diseases and reduce the stress in the first day of life of poultry chicks by eliminating the process of manually vaccinating each chick. The invention comprises an automatic system controlled by a PLC (programmable logic controller), using an injector that has a cylindrical body and cap made from high density non-corrosive plastic and together they form a pneumatic chamber, the cap containing an electronic contact sensor to signal empty egg spaces and avoiding wasting vaccine. The injector's pneumatic chamber contains a plasticized fiber sleeve to permit smooth movement of the pneumatic plunger.
