Title:
EGGSHELL STATE INSPECTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/082730
Kind Code:
A1
Abstract:
An eggshell state inspection device (1), provided with a striking body (2), a stress light-emitting body (6), a measurement unit (3), and a determining unit (10). The striking body (2) is caused to collide with an eggshell being inspected. The stress light-emitting body (6) is provided to the striking body (2), and emits light in response to deformation of the striking body (2) caused by the collision of the striking body (2) with the eggshell. The measurement unit (3) measures the amount of light released from the stress light-emitting body (6) by causing the striking body (2) to collide with the eggshell. The determining unit (10) determines the state of the eggshell on the basis of the amount of light obtained by the measurement unit (3). The eggshell state inspection device (1) is used to determine the state of an eggshell by observing solely the behavior of the striking body (2) side. The eggshell state inspection device (1) is also used to determine whether or not a crack is present in the eggshell. The eggshell state inspection device (1) is also used to inspect the difference in properties of eggshells in normal eggs.
