Title (EN) METHOD OF AND DEVICE FOR DETECTING CRACK IN EGGSHELL
(FR) PROCEDE ET DISPOSITIF SERVANT A DETECTER DES FISSURES DANS LA COQUILLE D'UN ×UF
Abstract:
(EN) An egg (8) to be examined is allowed to roll down under its own weight a plurality of planes (6) connected to each other through a plurality of steps (5) and to strike the planes (6) one by one while falling down the steps (5), whereby impact generated by the strike of the dropping egg on an impact receiving body (3) comprising the planes (6) is detected by an impact detector (12) and, from the intensity of the detected impact, a crack of the eggshell (8) is detected. The impact receiving body (3) is resiliently fixed to a base (1) through a resilient member (2).
(FR) On fait rouler un ÷uf (8) à examiner, sous l'effet de son propre poids, de sorte qu'il passe sur un ensemble de plans (6) reliés de manière à former un certain nombre de marches (5) et qu'il heurte les plans (6) l'un après l'autre en descendant les marches (5). Le choc produit par l'impact de l'÷uf tombant sur un élément (3) des plans (6) est détecté par un détecteur de chocs (12); l'intensité du choc détecté permet d'évaluer la présence d'une fissure dans la coquille (8). L'élément recevant les chocs (3) est fixé de manière résiliente sur une base (1) à l'aide d'un élément résilient (2).
