Abstract

Device (1) for inspecting and transferring eggs from a prehatching drawer (4) to a hatching tray (5), in which the device (1) contains two conveyor belts (2-3) that can respectively convey prehatching drawers (4) with prehatched eggs and empty hatching trays (5), whereby the device (1) contains an inspection unit (7) that has means to enable the prehatched eggs to be inspected, whereby the inspection unit (7) contains a transfer unit (8) to remove the rejected eggs from the prehatching drawer (4), whereby the device (1) contains at least one egg placement module (10-11) that can take all eggs out of a prehatching drawer (4) simultaneously and can separately place one or more of the eggs taken out.

Claims

1-17. -17. (canceled)

18. Device for inspecting and transferring eggs from a prehatching drawer to a hatching tray, comprising:

two conveyor belts arranged to respectively convey prehatching drawers with prehatched eggs and empty hatching trays;

an inspection unit for inspecting the prehatched eggs comprising a transfer unit arranged to remove rejected eggs from the prehatching drawers; and

at least one egg placement module arranged to take all eggs out of a prehatching drawer simultaneously and to separately place one or more of the eggs taken out.

19. Device according to claim 18, including one or more egg placement modules that are located downstream from the inspection unit.

20. Device according to claim 18, including a control unit that records the time for which an egg is in an egg placement module and that determines the priority for placing the eggs by taking said time into account, and that, when a time limit is exceeded, evacuates the egg and/or gives an acoustic signal and/or an optical signal.

21. Device according to claim 18, wherein between the inspection unit and a first egg placement module there is located an egg detection unit.

22. Device according to claim 18, wherein the egg placement module comprises a series of suction cups arranged to pick up and position the eggs, each suction cup being separately connected to a vacuum system arranged to apply an underpressure in the space within the suction cup.

23. Device according to claim 22, wherein the vacuum system comprises at least one vacuum chamber to which the suction cups are each connected separately via a pipe that is closeable by a valve.

24. Device according to claim 22, wherein each suction cup comprises a flexible housing with a variable length.

25. Device according to claim 22, including a control unit arranged to activate and deactivate the valves.

26. Device according to claim 18, wherein the inspection unit comprises a transfer unit arranged to pick up inspected eggs from the prehatching drawer and to place the eggs picked up in a hatching tray on the second conveyor belt.

27. Device according to claim 18, wherein the control unit includes an algorithm arranged to move the eggs picked up in the egg placement module to a position above the second conveyor belt.

28. Device according to claim 18, including a transfer unit arranged to pick up and to position all eggs from the prehatching drawer in a hatching tray.

29. Device according to claim 28, wherein the transfer unit is placed downstream from the egg placement module.

30. Device according to claim 28, wherein the prehatching drawer includes individual egg holders that are positioned in rows and/or columns with a fixed distance between them, and the egg placement module includes a means to move the egg placement module in a transverse direction over a distance that is at least equal to the aforementioned distance between the rows and/or columns.

31. Method for inspecting and transferring eggs, comprising the steps:

conveying prehatching drawers at least partially filled with prehatched eggs to an inspection unit one by one;

inspecting the eggs for the presence and/or viability of the embryo or chicken, and removing rejected eggs from the respective prehatching drawer; and

taking all eggs out of a first prehatching drawer in an egg placement module and placing one or more of the eggs taken out in a second prehatching drawer on the first conveyor belt or in a hatching tray on the second conveyor belt.

32. Method according to claim 31, wherein the number of eggs to be placed depends on the number of rejected and/or approved inspected eggs of the prehatching drawer.

33. Method according to claim 31, wherein the number of eggs to be placed depends on a target value.

34. Method according to claim 33, wherein the target value is set beforehand, or is set or adjusted by the user via a control unit.
