Abstract: A method of marking an egg is disclosed and comprises applying radiant energy to the shell of an egg so as to cause discoloration of the eggshell, thereby forming a marking comprising at least a traceability code and a freshness date. Apparatus is also disclosed for applying markings on eggs being processed by an egg-handling machine that is designed and configured to transport a plurality of eggs therethrough, wherein the apparatus comprises a radiant energy source located in proximity to the egg-handling machine, the radiant energy source being configured to apply radiant energy to the eggs as the eggs are transported past the radiant energy source to selectively discolor the shell of the eggs and form markings on the shell, including a freshness date and a traceability code.

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 container for eggs which uniformly orients eggs so that a substantial amount of surface area of the egg is uniformly presented for marking and viewing. The container has receptacles that may include one or more guidance features configured to automatically guide eggs to settle into a preferred resting orientation with the eggs uniformly centered and tilted slightly backward within their receptacles. The receptacles are designed to resist movement of the eggs from their resting orientation during marking, shipping or handling. Optionally, guidance and stabilizing features may cooperate to maintain eggs in a desired resting 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.

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 method for arranging eggs in a container. Eggs placed in receptacles of the container come to a resting orientation, by virtue of eh contouring of the receptacle, such that a long axis of the first egg is tilted toward a rear portion of the container at nearly uniform angles slightly offset from a vertical axis, and parallel side-to-side. Using features of the container, movement of eggs from their resting orientation, as well as twisting (spinning) about their long axes is resisted during marking, shipping or handling. The orienting of eggs in the receptacles or compartments thereof may be aided by use of an egg orienter. Tilting of the eggs may be facilitated by using receptacles or compartments which are asymmetrically contoured with respect to the vertical axis.

Abstract: Embodiments of the present invention comprise an apparatus for laser marking individual objects with indicia at a marking station wherein a predetermined window exists during which each object can be marked as the objects are conveyed along at least one path at a predetermined speed, the apparatus comprising, at least first and second lasers positioned adjacent one or more paths configured to direct a laser beam onto the objects to mark the same with indicia as the objects pass through the marking station, with each of the first and second lasers marking alternate following objects as they pass through the marking station.
