Title:
LOOSENESS DETECTION APPARATUS AND LOOSENESS DETECTION PROGRAM
Document Type and Number:
WIPO Patent Application WO/2023/089659
Kind Code:
A1
Abstract:
A looseness detection apparatus (50) detects looseness of a fixing member (20) provided to a rotary body (14). The fixing member (20) fixes the rotary body (14) to a fixing target object (12). The looseness detection apparatus (50) comprises a control device (52, 62) and a storage device (65). The control device (52, 62) determines whether or not, from image data obtained through imaging performed by an imaging device (57), a relative position between a first marker (31) provided to the rotary body (14) and a second marker (41) provided to the fixing member (20) has changed by a threshold value or more. The control device (52, 62) stores the relative position in the storage device (65). The control device (52, 62) determines that looseness has occurred in the fixing member (20) in a case where the relative position has changed by the threshold value or more.
