Abstract

The invention relates to a so-called stabilization method, consisting of completing the filling of traveling egg trays. In each of the successive trays, eggs taken from an available egg reservoir are deposited in empty locations. This reservoir is made up of egg receiving cells that are movable along rows of cells in series. Depending on a filling state of the tray being treated identifying the distribution of the empty locations relative to the full locations, the reservoir is automatically configured in a configuration of egg-bearing cells complementary to said filling state of the tray in progress, so as to next transfer eggs between the reservoir and the tray in progress by correspondence between empty locations and full locations in the tray and the presence or absence of an egg-bearing cell in the reservoir.

First claim

The invention claimed is:

1. A system for processing eggs, the system comprising:
a conveyor configured to convey egg trays containing eggs along a path;
transfer means positioned along the path and configured to transfer eggs from the egg trays;
a plurality of egg receiving cells disposed proximate to the transfer means for receiving eggs removed from the egg trays, the egg receiving cells being mounted to be individually movable in an available egg reservoir; and
automatically controlling drive means configured to control movement of the egg receiving cells, the drive means having a control device configured to automatically determine a placement of the egg receiving cells to receive the removed eggs, wherein the control device is further configured to direct the drive means to concentrate the egg receiving cells of the egg reservoir by bringing them, alongside one another by rows of egg receiving cells, toward a storage zone of the egg reservoir such that a line of demarcation is formed between egg-bearing egg receiving cells and empty egg receiving cells, and further wherein said drive means include a comb with retractable teeth that is mounted movably along said rows of egg receiving cells from one of their ends to the other across all of said rows, the teeth of the comb each being assigned to one of said rows of egg receiving cells and individually controlled between an active position driving an egg receiving cell of the corresponding row with which it engages and an inactive position where it withdraws away from the egg receiving cells while the comb travels over all of the rows of egg receiving cells.

2. The system according to claim 1 , wherein the transfer means comprise a suction plate having individual grasping means for grasping eggs that are distributed in as many lines and columns as each of said traveling egg trays has egg locations.

3. The system according to claim 1 , wherein, in each of said rows, the egg receiving cells are mounted in series on a guide rail guiding their movements and in that, in each series, the egg receiving cells are alongside and against one another on said rail such that the egg receiving cells push one another along said rail when one of the egg receiving cells is commanded to move.

4. The system according to claim 1 , wherein said comb comprises a support arm having a plurality of jack devices, each jack device bearing a finger forming one of said retractable teeth of said comb.

5. The system according to claim 1 , wherein each movable egg receiving cell of the egg reservoir has a driving tab with which the corresponding comb tooth engages when it is deployed in the active position to move in one direction or the other along a guide rail of the egg receiving cells in series in the same row.
