Claims8
A gripper device for displacing an egg-tray filled with eggs comprising:
- supporting members movable in a generally horizontal direction into engagement with a rim of an egg-tray, said supporting members having an edge gripping portion of a height greater than the thickness of the rim of the tray, said thickness being taken in a vertical direction, such that the vertical position of the rim can be varied over a given range, relative to the said edge gripping portion, and still be positioned to be gripped by the edge gripping portion and hence carried by the supporting members,
- a suction device comprising means for engaging the eggs in the tray by suction to support the weight of the eggs therein,
- and means for fixing the height of the supporting members relative to the suction device and moving them together to thereby carry away the egg-tray filled with eggs with the suction device bearing the weight of the eggs and supporting members bearing the weight of the tray.
