An apparatus to identify upside-down eggs of a batch of eggs includes a heating module configured to expose an air cell in each egg of the batch of eggs to a radiation flux. The apparatus also includes an imaging module with a thermal camera configured to capture thermal images of the batch of eggs when the eggs are not exposed to the radiation flux. The apparatus further includes an analyzer module configured to detect the presence of a heated zone in the air cell of each egg from the thermal images and identify upside-down eggs based on the presence of the heated zone. A method to identify upside-down eggs from a batch of eggs includes heating the batch of eggs with a radiation source, such as an infrared source, so as to generate a hot zone inside an air cell of each egg without significantly heating the rest of the eggs. Thermal images of the eggs are captured while the eggs are not exposed to the radiation source, analyzed to detect the presence of the hot zone and to identify the upside down eggs.

An egg conveyor assembly is provided herein. The egg conveyor assembly includes a first conveyor extending in a first conveyor direction on a first height level, a second conveyor extending in a second conveyor direction perpendicular to the first height level. A transfer device adapted to transfer eggs from the first to the second conveyor includes an array of egg retainers. The egg retainers include pockets having a receiving opening at an upper end thereof to receive the eggs from above from the first conveyor, and are adapted to release the eggs at a lower end to drop the eggs in egg retainers of the second conveyor. The transfer device is movable in the first conveyor direction and in the second conveyor direction in a plane on a height level between the first height level and second height level.

A device for reorientation of eggs deposited in the hollow open cells of a tray. The device is intended to reorientate at least one egg from the tray along a substantially vertical axis. The device includes at least one reorientation element capable of moving between a low position and a high position with respect to the cell containing the egg to be reorientated. The reorientation element includes a lower seat on which the upright rods are fixed, the upper ends of the rods being able to spread out with respect to each other on contact with the egg to be re-orientated, the upright rods being intended to interpose themselves between the cell and the egg, in the high position, so as to damp and guide a movement of the egg under the effect of its weight to a substantially vertical position.

An endless egg conveyor is provided. The conveyor includes an endless element running around a set of rotational wheels and a drive unit defining a conveying direction. The conveyor has an upper run and a lower run and head sections where the direction of movement of the endless element is reversed. The conveyor also includes an egg retaining pocket coupled to the endless element, moving in the conveying direction. The retaining pocket has a central axis and an upper receiving opening to receive an egg with a longitudinal axis of the egg aligned with the central axis. The retaining pocket is coupled to the endless element by a bearing structure allowing rotation of the retaining pocket around a rotational axis extending parallel to the rotational axes of the rotational wheels, allowing the retaining pockets to remain in an upright position in every position in the lane. Adjacent retaining pockets of different lanes define a pocket row, wherein, the conveyor includes carrying elements that carry the pockets of one row. The bearing structure of each pocket row includes a support arm on either lateral side of the conveyor. The support arm is positioned upright with respect to the circulating endless element and connected thereto. The bearing structure of the pocket row includes a spindle connected to the carrying element, which pivotally connects the carrying element to the support arms.

An egg printing system comprises a printer (30, 31, 32) and an endless egg conveyor (1) that is adapted to move the eggs (50) past the printer. The conveyor including an endless element running around a set of rotational wheels and a drive unit defining a conveying direction of the conveyor. The egg conveyor includes a lane of egg retaining pockets (10) coupled to the endless element, said lane of retaining pockets in use moving in the conveying direction. 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.
