Abstract

See full text

A device can prevent a failure in the actuation of a braking mechanism, which is caused by adhesion of adhesive substances. The device includes a heating part for heating the braking mechanism, a heat controller for controlling a heating operation of the heating part, a brake controller for actuating the braking mechanism when the heat controller stops the heating operation, and the temperature of the braking mechanism decreases, an actuation delay measuring part for measuring an actuation delay of the braking mechanism when the brake controller actuates the braking mechanism, and a comparison part for comparing the actuation delay measured by the actuation delay measuring part with a reference value of the actuation delay of the braking mechanism.
