## Abstract

An egg chain gripper actuating device for use with an egg transfer device. The device has an egg conveyor with parallel egg chains movable in a transport direction, each chain supporting egg grippers, which can be individually actuated. The device further comprises an egg receiving unit with a receiving area for receiving eggs released by the egg grippers, and one group of one or more actuators for each egg chain for selectively actuating passing egg grippers. Multiple support frames are provided, each supporting one or more groups of actuators. At least one frame is adjustable parallel to the transport direction and relative to another frame, such that the position of the actuators of the one or more groups supported by the frame can be adjusted relative to the position of the one of more actuators of the one or more groups supported by the other frame.

## Claims

### Claim 1

an egg conveyor with two or more parallel egg chains movable in a transport direction, each egg chain supporting a plurality of egg grippers each adapted to support an egg, which grippers can individually be actuated from a closed position, for supporting an egg, into an open position, for releasing an egg, the egg conveyor further comprising an egg chain conveyor drive for driving the egg chains at a transport speed;
an egg receiving unit with a receiving area for receiving eggs released by the egg grippers which receiving area is defined by at least one brush wheel rotatable about an axle parallel to the transport direction of the egg chains and which is located below the egg conveyor such that the vertical distance between one egg chain and the receiving area is larger than the vertical distance between another egg chain and the receiving area;
wherein the egg chain gripper actuating device comprises:
one group of one or more actuators for each egg chain, which actuators are designed for selectively actuating passing egg grippers into an open position to release an egg such that the released egg follows a parabolic trajectory from a release spot at which it is released by the gripper to a contact spot at which it contacts the receiving area; and
multiple support frames, each supporting one or more groups of actuators, of which at least one frame is adjustable parallel to the transport direction and relative to another frame, such that the position of the actuators of the one or more groups supported by the frame can be adjusted relative to the position of the one or more actuators of the one or more groups supported by the other frame.

### Claim 2 (depends on 1)

An actuating device according to claim 1, wherein at least one frame supports two or more groups of actuators for locating along two or more egg chains respectively, which chains are located at a similar vertical distance above the receiving area such that they drop their eggs along parabolic trajectories of similar shape and length.

### Claim 3 (depends on 1)

An actuating device according to claim 1, further comprising at least one drive for adjusting the position of one or more support frames, and a control device to control the at least one drive.

### Claim 4 (depends on 3)

Egg transfer device according to claim 3, wherein the control device is designed for receiving egg chain conveyor transport speed information and to use this information to control the at least one drive to adjust the position of the one or more movable frames linked to the drive in dependence of the transport speed.

### Claim 5 (depends on 1)

An actuating device according to claim 1, wherein the adjustment of a first set of one or more adjustable support frames for supporting one or more groups of actuators adjacent one or more egg chains located at a first vertical distance above a receiving area, is linked to the adjustment of at least one second set of one or more adjustable support frames for supporting one or more groups of actuators adjacent one or more egg chains located at a second vertical distance above a receiving area, which second vertical distance differs from the first vertical distance, such that when the position of the first set of frames is adjusted to compensate for a change in speed of the egg chains, the position of the second set of frames is correctly adjusted also.

### Claim 6 (depends on 5)

An actuating device according to claim 5, wherein the at least two sets of adjustable support frames are mechanically linked, such that one drive can be used to move each set over a different distance.

### Claim 7 (depends on 5)

An actuating device according to claim 5, wherein the at least two sets of adjustable support frames are each linked to a drive via a separate transmission, which transmissions are designed such that the one drive can be used to move each set over a different distance.

### Claim 8 (depends on 5)

An actuating device according to claim 5, wherein the at least two sets of adjustable support frames are each provided with a drive, and the control device is designed to control the drives such that each set can be moved over a different distance.

### Claim 9 (depends on 1)
