Each retaining pocket has a central axis and an upper receiving opening to receive an egg with a longitudinal axis of the egg generally aligned with said central axis of the pocket. The pocket has a side opening at a side thereof facing in the conveying direction and/or in the opposite direction, leaving a side surface area exposed of the egg that is received in the pocket. The retaining pockets remain in an upright position in every position in the lane. The printer is positioned at one of the head sections of the conveyor with a printing head facing the corresponding lane being directed to said side opening in the pocket to allow printing on said side surface area of the egg.
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 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 transfer system for providing faster and increased volume processing of eggs having an overhead positioned egg conveyor. A rotating brush wheel positioned underneath the conveyor receives eggs and includes a first and second pluralities of bristles having, respectively, lesser and greater stiffness. An egg receiving reservoir exhibits a receiving lane positioned underneath and in alignment with the brush wheel for receiving and redirecting the eggs in a lane dedicated fashion to a subsequent egg handling operation. A plurality of spool bars are arranged in parallel extending and spaced apart fashion and defining a number of individual egg conveying lanes and each further include first and second spool bar portions secured in end-to-end fashion to establish an overall dimension. First and second drive supports are arranged at opposite ends of the spool bar portions, a third drive support arranged within the egg transfer mechanism and supporting opposing and intermediate engaging ends of each pair of spool bar portions. The intermediate drive support prevents sagging of the intermediate ends of the spool bar portions.
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. Further, in some embodiments, the position of the one or more eggs in the package may be adjusted so that a long axis of each egg in the package is tilted toward the back of the package so as to be at least slightly offset from vertical and/or so 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:
The present invention discloses a novel construction arrangement in a packaging machine for incubator trays, which enables the general automation of the packaging process of eggs in incubator trays. The packaging machine for incubator trays accepts several arrangements and capacity for four, five, six and twelve eggs, depending on the incubator trays to be used. The packaging machine for incubator trays of the present invention exhibits great improvements. One of these great improvements is related to the introduction of an automatic feeder for trays, commonly called tray dispenser or denester for incubator trays. Another great improvement refers to a constructive change in one of the main elements of the disclosed machine, and this change was made in order to stop vibrations that the eggs were eventually exposed. The benefits obtained from the use of the packaging machine for incubator trays, the main object of this invention, are related to the possibility of greater automation of the process. In addition, the transport of eggs occurs in a more secure and constant way, decreasing the number of broken and/or damaged eggs.
Abstract:
A shifting apparatus for objects such as eggs comprises a plurality of holders slidably carried on a substantially horizontal holder guide which is vertically movable. When the holder guide assumes an upper position, the holders are maximally spaced from each other for receiving a corresponding number of objects from above. A pitch changing mechanism causes the holders to slide on the holder guide, so that the holders are minimally spaced from each other when the holder guide assumes a lower position. In the lower position of the holder guide, a discharging mechanism causes the holders to discharge the received objects into a container located below.
