Abstract: A method for marking an egg shell wherein a laser beam is directed onto the egg shell so as to discolor an outer layer of the egg shell without etching substantially into layers of the egg shell underneath the outer layer. The laser delivers a spot with a power density below about 2000 watts/sq. in. and a depth of an etching of the egg caused by the laser marking process does not exceed about 25 microns. InkJet printing may be added to the laser marking process or used instead of laser marking. Eggs may be marked in-carton, on a packer conveyor or on an apparatus fed by a packer conveyor, with eggs uniformly oriented in the package prior to (and after) printing. Marking is done in-carton, on-conveyor whether the marking is by laser, by ink, or both.

Abstract: A system for laser marking eggs is disclosed comprising multiple laser marking apparatuses and a central server. The laser marking apparatuses are configured and arranged to perform laser marking jobs queued by local computers for laser marking eggs being packed by egg packing stations. The central server is configured to distribute the laser marking jobs to the local computers. In addition, a method is disclosed for controlling laser marking jobs which comprises distributing the laser marking jobs from a central computer to local computers responsible for queuing laser marking jobs to one or more laser marking apparatuses configured and arranged to laser mark information on eggs.

Abstract: A method for processing a package of eggs is disclosed which comprises adjusting a position of one or more of the eggs, after the eggs have been placed in the package, so that each of the eggs assumes a particular orientation within the package. In some embodiments, the method may also comprise marking information on a surface of one or more of the eggs after the position of the one or more of the eggs has been adjusted. Additionally, in some embodiments, the position of the one or more eggs may be adjusted using an egg orienter positioned above a conveyor of an egg packing station.

Abstract: An apparatus for processing packages of eggs on a conveyor is disclosed which comprises an egg orienter configured and arranged with respect to the conveyor so as to adjust a position of one or more of the eggs in each of the packages so that each of the eggs in a given package assumes a particular orientation within that package. In some embodiments, the egg orienter may be located between an egg loading section and a package closing section of an egg packer. In addition, in some embodiments, the apparatus may further comprise a laser source and one or more optical steering elements configured and arranged to direct laser energy from the laser source so as to laser mark information on a surface of one or more of the eggs while the eggs are in a package disposed on the conveyor and in said particular orientation.

Abstract: A method for laser marking eggs is disclosed which comprises laser marking information onto one or more eggs while the eggs are in a package disposed on a conveyor of a packing station. Additionally, an apparatus for laser marking eggs on a conveyor of a packing station is disclosed which comprises a laser source and one or more optical steering elements configured and arranged to direct energy from the laser source so as to mark information onto one or more eggs in packages of eggs disposed on the conveyor.

Abstract: A package of eggs is disclosed which comprises a plurality of eggs arranged in one or more rows. The eggs are further arranged in the package so that a long axis of each egg in the package is offset no more than a particular number degrees from a long axis of each other egg in the package. Further, a package of eggs is disclosed which comprises a plurality of eggs arranged in one or more rows, wherein eggs are arranged in the package such that long axes of all of the eggs in each row of eggs in the package form approximate right angles with respect to a line intercepting bottoms of receptacles holding the eggs in such a row.
