<P>PROBLEM TO BE SOLVED: To solve such a problem that a cracked egg detection unit in accordance with a conventional chicken egg sorter may be affected by vibration sound generated from an egg conveyed in another row, and it erroneously determines the "presence of crack" even when an egg shell of a chicken egg has no crack, and determines the "absence of crack" even when it has a crack. <P>SOLUTION: In the chicken egg sorter, a cracked egg detection unit 2 provided on a plurality of rows of supply conveyance units 1 conveying chicken eggs E is provided with a sound insulation part 23. Accordingly, an erroneous determination rate is reduced because it is not affected by the vibration sound generated from the chicken eggs E conveyed in the other rows. Further, since a plurality of hammer units 20 may be adjacently installed, the total length of the cracked egg detection unit 2 is reduced while decreasing the erroneous determination rate as compared with the conventional one. <P>COPYRIGHT: (C)2012,JPO&INPIT |
