An egg-examining device, comprising a sampling device, by which a liquid sample to be taken can be taken from an egg of a rack loaded with eggs, a feeding device for feeding the rack loaded with eggs to the sampling device, and a control unit, by which the feeding device and the sampling device can be controlled. The feeding device feeds the rack to the sampling device at an oblique angle of between 20° and 80° to a plane perpendicular to the direction of gravity. A lifting-out device is provided, by which the egg can be lifted out of the rack and by which the egg can be put into a sampling position, in which the liquid amount to be taken can be taken from the egg by the sampling device.

An egg orientation device is adapted to put eggs (10, 10′) point down or point up in egg retainers (6). The egg orientation device comprises a stationary lane having a support plate (2) comprising a central zone (3) and two lateral zones (4). The device furthermore comprises a pusher (20) movable in a conveying direction along the lane and adapted to push an egg such that it rolls over the support plate around its longitudinal axis. An egg retainer is movable in the conveying direction beneath the support plate of the lane in a synchronised manner with the pusher. At least one drop opening (5, 7A, 7B) is provided in the support plate, which allows eggs to fall through and drop point down or point up in the egg retainer that is positioned underneath the drop opening. The drop opening is located in the central zone or in at least one of the lateral zones for dropping the eggs in the egg retainer point up and point down respectively.

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.

A laying nest is provided with an improved ejection system, in which the risk of expelling eggs together with the hens is suppressed. The floor of the laying nest can rotate in both directions. Thanks to this arrangement, at first it can be rotated in a first direction for inclining it towards the egg collection area and ensuring that all the laid eggs are removed; next, it can be rotated in a second, opposite direction for inclining it towards the hen coop and thus expelling the hens from the laying nest. In a preferred embodiment, the driving arrangement of the ejection system of the laying nest is entirely arranged below the floor of the laying nest, so as to not occupy room in the laying nest and to be protected from manures and dirt that may be present in the laying nest.

An egg conveyor for a poultry plant includes a chain of the closed-loop type with bars, for conveying eggs from one or more laying hen sheds to a collection location, assemblies for traction along the chain which are provided with a motor drive component, and a control unit for synchronization of the traction assemblies. The motor drive components each include at least one gearmotor provided at least with a corresponding servomotor. The method for synchronization of traction assemblies in the conveyor includes the following steps: detecting continuously and instantaneously the angular position and the number of bars at each traction assembly, and calculating continuously and instantaneously the average of all the torques at the traction assemblies and, if the number of bars is different from a set number, correcting the speed of each servomotor to obtain a constant torque on each traction assembly, which corresponds to the average.

The present invention provides an apparatus for transferring products, for example eggs, from an endless conveyor to carrier units, comprising—the conveyor with at least a single row of transport carriers, and—a transfer unit positioned near the conveyor, which further comprises an arm pivotable around a shaft and having at its end a transfer carrier, wherein the relative velocities upon takeover from the conveyor and upon transfer to such a carrier unit are virtually 0 m/s, and wherein the shaft is driven by a motor with independently controllable speed. Furthermore, the present invention provides a method for, from an endless conveyor having transport carriers for carrying along products, transferring therefrom the products, for example eggs, to carrier units.

An egg conveyor assembly (1) comprises a first conveyor (4) having a first conveyor direction (X), a second conveyor (5) extending in a second conveyor direction (Y) transverse to the first conveyor direction (X) and a transfer device (6) arranged between the first conveyor and the second conveyor. The transfer device includes a transfer conveyor comprising and endless element (60) and extending in the second conveyor direction (Y). The second conveyor circulates second egg retainers (52) continuously, and the transfer conveyor circulates egg transfer retainers (62) discontinuously, in such that the egg transfer retainers of the transfer device are approximately standing still when receiving eggs from the first conveyor, and such that the egg transfer retainers of the transfer device are moving approximately synchronously with second egg retainers of the second conveyor when dropping the eggs in the second egg retainers of the second conveyor.

A transfer device for transferring eggs from a conveyor belt to egg packaging, the transfer device includes a frame with at least one mounting plate of a mounting element, on which mounting plate a plurality of suction lifting elements that can be connected to a suction apparatus are mounted. The suction lifting elements are mounted on the mounting plate so as to be movable in the plane of the mounting plate by motorized or hydraulic means between a suction position and a release position.

An egg-examining device, comprising a sampling device, by which a liquid sample to be taken can be taken from an egg of a rack loaded with eggs, a feeding device for feeding the rack loaded with eggs to the sampling device, and a control unit, by which the feeding device and the sampling device can be controlled. The feeding device feeds the rack to the sampling device at an oblique angle of between 20° and 80° to a plane perpendicular to the direction of gravity. A lifting-out device is provided, by which the egg can be lifted out of the rack and by which the egg can be put into a sampling position, in which the liquid amount to be taken can be taken from the egg by the sampling device.

A part-processing machine having, in series, consecutive parts on a belt (2) moving same along a main conveying line. Selectively identified non-compliant parts are removed from the conveying line, into a transfer device (1) by pickup tools (8) supported on the periphery of a rotating drum (6) mounted transversely to the conveying line and arranged to rotate about itself so as to pass over the belt, enabling the non-compliant parts to be picked up by the pickup tools and released once the parts have been transported away from the conveying line. The pickup tools have pneumatic gripping heads, more particularly for example suction cups. The pneumatic gripping heads are depressurized relative to the surrounding air by a low-pressure chamber provided inside the drum, to which each head is connected by a tube inside a tool support arm.
