An object of the present invention is to provide an automatic egg detection mechanism that automatically determines and eliminates dirty eggs with high accuracy regardless of eggshell color, and an egg sorting and packaging system including the same. An illuminating unit 4 and a diffuse reflector 5 arranged on the inner wall of an egg examination room 2 irradiate a group of eggs E with light having a wavelength of 300 nm to 500 nm, and π electrons in excited eggshell pigments are in a ground level. The contrast between the eggshell surface and dirt adhering to the surface is emphasized by the fluorescence of 600 nm to 700 nm emitted in the process of returning to. The image processing device 7 creates a binary image at a plurality of binarization levels from the image of the egg group taken by the CCD camera 3 on the basis of the luminance value of each eggshell. The number of eggs is read to comprehensively judge the egg. If the egg detection mechanism 1 is mounted on the double row transport mechanism of the egg sorting and packaging system and is synchronized with the egg sorting and packaging system by the sensor 9, the control device 10, and the system control unit 22, the eggs are stained with high accuracy regardless of the eggshell color. Can distinguish and eliminate eggs. [Selection] Figure 3 |
