DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
This invention relates to an apparatus for breaking and opening eggs in a controlled way and for catching and removing the yolks and egg whites, said apparatus comprising
at least one supply belt for feeding eggs to a conveyor equipped with egg carriers, comprising egg-receiving and opening elements,
the conveyor being a first conveyor whose egg carriers, after the eggs have been opened, transfer the contents of the eggs to holders with cups mounted on a second conveyor which travels in alignment with, and is located under, the first conveyor at least for the portion of the path of travel where the contents of the eggs are transferred.
Such apparatus is known from GB-A-914,629. This apparatus is a rather complicated construction, having three transfer points and a handling capacity which is limited by the number of individual egg opening elements, that can be placed at the periphery of the frame structure.
SUMMARY OF THE INVENTION
It is an object of the invention to provide an apparatus of the above described type having a simplified construction with less transfer points, an increased handling capacity within about the same volume and the possibility of visual inspection, in which apparatus the eggs are positioned with their longitudinal axes placed horizontally during the cracking and emptying steps.
According to the invention an apparatus is provided in which
each egg carrier of the first conveyor is directed transversely to the direction of travel of said first conveyor and comprises a plurality of juxtaposed egg-receiving positions with opening elements, the eggs being positioned in said positions with their longitudinal axes oriented in the direction of travel of said first conveyor,
the number of supply belts being equal to the number of egg-receiving positions on each egg carrier, each supply belt being arranged in such a way that it transfers the eggs supplied exclusively to a defined one of the plurality of juxtaposed egg receiving positions.
In the apparatus according to the invention the first conveyor combines the functions of feed conveyor and frame structure, by mounting egg carriers comprising opening elements on said first conveyor. These egg carriers are adaped to support a plurality of eggs, two in the embodiment shown. The problem of delivering eggs in the correct egg receiving position on said egg carriers is solved by installing as many separate supply belts as there are egg receiving positions on each carrier, each supply belt delivering eggs to a defined egg receiving position on an egg carrier.
Preferably each egg holder of the second conveyor comprises a plurality of separate, juxtaposed cups for receiving the yolks and egg white from the broken eggs, present in the egg receiving positions which cups are located under the plurality of juxtaposed egg receiving positions of the first conveyor when both conveyors are traveling in alignment with each other.
Each egg carrier is preferably pivotally connected to a holder element of the first conveyor, whereas, the different supply belts are mounted at a different height level in such a way that the transfer end of each supply belt is located at about the same distance above the related egg receiving position of the downwardly pivoted egg carriers.
An embodiment of an apparatus according to the invention will now be described with reference to the accompanying drawings, in which:
FIG. 1 is a top plan view of an apparatus for breaking and opening eggs in a controlled way and for separating and separately catching and removing yolks and egg whites;
FIG. 2 is a section taken on the line II--II of FIG. 1;
FIG. 3 is a section taken one the line III--III of FIG. 1;
FIG. 4 is a section of a part of the apparatus according to FIG. 2; and
FIG. 5 is a section similar to FIG. 3 of a part of the apparatus according to another embodiment of the egg breaking apparatus according to the invention.
DESCRIPTION OF PREFERRED EMBODIMENTS
Referring to the drawings and FIG. 1 in particular, an apparatus for breaking and open
