This invention relates to an apparatus for receiving and transporting a stream of eggs, comprising, a conveyor for transporting eggs in a transport direction T, a releasing device connected with the conveyor, for releasing predetermined eggs away from the conveyor, separately, downwardly out of the stream, a guide for receiving and taking over such an egg from the releasing device and guiding it to an egg processing apparatus, and two driven star wheels placed substantially close to each other, with shafts perpendicular to T, and with opposite directions of rotation of the shafts, while upon rotation their blades along a part of the rotation path are placed over each other and transport the eggs substantially cupwise downwardly. In a suitable manner, with this apparatus, for example intact but dirty eggs can be released from a sorting stream and be received for further handling or processing.

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.

An egg conveyor assembly comprises a first conveyor (1) extending in a first conveyor direction (X) on a first height level, a second conveyor (2) extending in a second conveyor direction (Y) perpendicular to the first height level. A transfer device (3) adapted to transfer eggs (50) from the first conveyor (1) to the second conveyor (2) comprises an array of egg retainers (6). The egg retainers (6) of the transfer device (3) comprise pockets having a receiving opening at an upper end thereof to receive the eggs (50) from above from the first conveyor (1), and are adapted to release the eggs at a lower end to drop the eggs (50) in egg retainers (21) of the second conveyor (2). The transfer device (3) is movable in the first conveyor direction (X) and in the second conveyor direction (Y) in a plane on a height level between the first height level and second height level.

An automatic egg tray stacking apparatus turns alternate egg trays through the operation of movable guides at the junction with a loading conveyor before conveying the egg trays toward a stacking mechanism that first stops the egg tray and then lowers the stack on top of the egg tray before re-elevating the partially formed stack to permit the entrance of a new egg tray into the stacking mechanism. Once the stack of egg trays is completed, the stack is allowed to move onto a stack conveyor and is moved forwardly for shipment. The stacking mechanism is operated by a single actuator having dual pneumatic cylinders that provide a three position operation of the lifting function with the stacking mechanism having lifter members engaging all four sides of the lowermost egg tray of the elevated stack. A control mechanism operates the apparatus with input from appropriately positioned sensors.

An egg orientation device is provided to position eggs downwards or upwards in egg retainers. The device includes a stationary lane with a support plate. The support plate includes a central zone and two lateral zones. The device also includes a pusher movable along the stationary lane and configured to push an egg over the support plate and around its longitudinal axis. The egg retainer is also movable in the beneath the support plate of the stationary lane in a synchronized manner with the pusher. A drop opening is provided in the support plate. The drop opening enables eggs to fall through such that they are positioned downwards or upwards in the egg retainer positioned beneath the drop opening. The drop opening is either located in the central zone or in the lateral zone.

An endless egg conveyor includes an endless element running around a set of rotational wheels and a drive unit defining a conveying direction of the conveyor. The conveyor has an upper run and a lower run and head sections Where the direction of movement of the endless element between the upper run and the lower run is reversed. The conveyor furthermore includes at least one lane of egg retaining pockets coupled to the endless element, moving in the conveying direction. Each of the retaining pockets has a central axis and an tipper receiving opening to receive an egg with a longitudinal axis of the egg generally aligned with said central axis. The retaining pockets are each 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 said 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 comprises carrying elements that carry the pockets of one row. The bearing structure of each pocket row comprises a support arm on either lateral side of the conveyor. The support arm is positioned upright with respect to the circulating endless element and rigidly connected thereto. The bearing structure of said pocket row comprises at least one spindle rigidly connected to the carrying element which pivotally connects the carrying element to the support arms.

A device for controlling the temperature of foods along a conveying path includes a buffer unit arranged in a region between a loading station and an unloading station. The buffer unit has at least two deflecting rollers. A first deflecting roller engages, in a first portion of a conveying device, in a continuous conveying chain, continuous conveying belt, or the like, which moves from the loading station toward the unloading station when driven. A second deflecting roller engages, in a second portion of a conveying device, in the continuous conveying chain, continuous conveying belt, or the like, which moves from the unloading station toward the loading station when driven. The first drive unit is coupled in the region of the loading station and a second drive unit is coupled in the region of the unloading station to the continuous conveying chain, continuous conveying belt, or the like.

The present invention relates to an endless conveyor for transporting products, for example packaging units, along a transport path in a transport direction T, wherein the conveyor comprises: freely rotating supporting rollers (2) which extend substantially perpendicular to the transport direction, which are connected at both ends to conveyor elements (3), and which form an endless transport surface, and flights (4), connected to the conveyor at well-defined positions, which with a control are movable to and away from a carrying position above the transport surface, wherein, after such carrying position has been taken up, a product present on the transport surface is carried along in the transport direction T, wherein the flights comprise strip-shaped thresholds (41) which, from a rest position below at least the transport surface, can be moved up between the rollers to the carrying position. Suitable to carry and buffer along products over an incline and thus transport them.

A packaging dispenser, for dispensing stacks of nested trays to a packing device, has a frame, a first conveyor for conveying and supporting a first plurality of stacks of nested trays in a first level, and a second conveyor downstream of the first conveyor for receiving stacks of nested trays from the first conveyor. The packaging dispenser also includes a vertical chute underneath the second conveyor for dispensing stacks of nested trays to a packing device. The second conveyor has a pair of laterally spaced conveyor elements for supporting only lateral edge regions of a stack of nested trays. The laterally spaced conveyor elements are retractable to allow a stack of nested trays, supported thereon, to be released into the chute. The packaging dispenser can further be provided with a tray separator upstream of the chute for loosening individual trays of a stack, while keeping the trays in a stacked and nested arrangement.
