Apparatus for automatically loading eggs directly from stacks of egg-filled flats
First Claim
1. An apparatus for automatically loading eggs directly from stacks of alternately rotatably oriented flats of eggs comprising:
- (a) a stack supply means for conveying stacks of egg-filled flats to a loading station;
(b) an egg removal means located adjacent the loading station and adapted to remove eggs from the uppermost flat of each stack of flats;
(c) a flat removal means positioned adjacent the loading station and adapted to remove from each stack of flats an uppermost empty flat after the eggs have been removed therefrom by said egg removal means; and
(d) a stack rotation means located adjacent the loading station and adapted to rotate each stack of flats approximately 90°
after each empty uppermost flat has been removed to orient the resulting uppermost egg-filled flat with respect to said egg removal means to facilitate removal of eggs therefrom and with respect to said flat removal means to facilitate removal of flats therefrom.

Abstract
An apparatus and method for automatically loading eggs directly from stacks of alternately rotatably oriented flats includes a conveyor for supplying stacks of eggs to an egg loading station which includes a device for removing of the eggs from the uppermost flat and for removing the uppermost now empty flat. The device includes a device for rotating and lifting the stack after the flat is removed to orient the stack for the removing of the next layer of eggs. Such a configuration is made necessary since such stacks of eggs are normally arranged with each layer of eggs being rotated 90° with respect to the next layer of eggs and since the array of eggs is normally not square it is necessary to reorient the stack each time a layer of eggs and the associated flat is removed therefrom. For this reason the present invention includes a stack rotation device in addition to a flat removal device, an egg removal device and a stack supply means.

10. An apparatus for automatically loading eggs directly from stacks of alternately rotatably oriented flats of eggs comprising:
-
(a) a stack supply means for conveying stacks of egg-filled flats to a loading station; (b) an egg removal means located adjacent the loading station and adapted to remove eggs from the uppermost flat of each stack of flats; (c) a flat removal means positioned adjacent the loading station and adapted to remove from each stack of flats an uppermost empty flat after the eggs have been removed therefrom by said egg removal means, said flat removal means further comprising at least one gripper means adapted to grasp an empty flat on opposing sides thereof for lifting and removing from a stack of egg-filled flats; and (d) a stack orientation device for lifting and rotating each stack after each empty flat is removed therefrom, said stack orientation device being positioned below the stacks of flats located on said stack supply means and adapted to move upwardly to lift and rotate the stack of flats after each empty flat is removed by said flat removal means, said stack orientation device including; 1. a stack rotation means located adjacent the loading station and adapted to rotate each stack of flats approximately 90°
after each empty uppermost flat has been removed to orient the resulting uppermost egg-filled flat with respect to said egg removal means to facilitate removal of eggs therefrom and with respect to said flat removal means to facilitate removal of flats therefrom;2. a stack lifting means positioned at the loading station adjacent said stack supply means and adapted to selectively lift a stack of flats located therein to facilitate removal of eggs by said egg removal means and to facilitate removal of flats by said flat removal means; said stack orientation device further including a lifting platform and a plurality of protruding devices extending upwardly therefrom and carried thereon wherein said protruding device extends into the undersurface of the lowermost flat to secure the stack of flats with respect to said stack orientation device for lifting and rotating therein.

11. A method for automatically loading eggs directly from stacks of alternately rotatably oriented flats of eggs comprising:
-
(a) conveying a stack of egg-filled flats to a loading station; (b) continuously unloading of the eggs and flats wherein said unloading includes; 1. removing the eggs from the uppermost flat of the stack of egg-filled flats; 2. removing the empty uppermost flat from the stack of egg-filled flats; and 3. rotating the remaining stack of egg-filled flats approximately 90°
to orient the next uppermost flat with respect to the egg removal means and the flat removal means. - View Dependent Claims (12, 13, 14, 15, 16)
