<p>A screw inspection device of the invention has a screw transfer mechanism (21) for transferring a screw through a predetermined transfer path (24), a sensor (30, 34, 36, 42) for performing predetermined measurements of the screw during transfer thereof, a timing signal transmitter (28) for generating a timing signal every time the screw reaches the sensor (30, 34, 36, 42), a comparator (43, 44, 45) for generating an acceptance/non-acceptance signal representing the measurement results from the sensor (30, 34, 36, 42) every time the timing signal is received, a sorting signal generator (46) for generating a sorting signal corresponding to the acceptance/non-acceptance signal when the corresponding screw reaches the end of the transfer path (24), and a sorter (47) for classifying the screws into defective and nondefective screws.</p> |
