PROCEDURE FOR IN-OPERATION CONTROL OF EGGS PLACED IN CONTAINERS

Abstract

The present invention relates to a method and apparatus for inspecting, as they pass, eggs placed in containers. According to the invention, during the movement of these containers (1) along a conveyor line, the following steps are carried out: triggering a data acquisition cycle on each passage of a downstream end of a container (1) through a first position, which is determined by a first position sensor (6) placed along said conveyor line, upstream and downstream positions being considered with reference to the direction of movement of the containers; then, for a data acquisition cycle of a container (1), detecting the passage of said downstream end of said container (1) through at least a second position determined by a second position sensor (7-8) placed along said conveyor line, a signal triggering thermal image acquisition being sent to a thermal camera (5) each time said downstream end of said container (1) is detected at at least a second position in order to trigger capture of one or more thermal images by said thermal camera (5) of the portion of the container (1) then placed in its field of view, said second position sensors (7-8) being arranged with respect to one another to ensure an inspection of all of the eggs of the container (1) considered by said thermal camera (5) when a plurality of second sensors are employed. Furthermore, the data acquisition cycle of said container comprises performing, in a third position separate from said first and second positions, a step of candling the eggs placed in said container, in which step a light flux is emitted in the direction of at least one egg to be candled and the light flux passed through each corresponding egg is then analysed depending on the level of light flux absorbed by the egg, and said data thus acquired on the eggs of a container (1) are associated with a unique identifier of this container (1).
