PROBLEM TO BE SOLVED: To provide a detection device of roller rotation failure where the detection accuracy of the rotation failure of a support roller is improved.SOLUTION: A detection device 14 of roller rotation failure comprises: main measurement parts 31 to measure the temperature of support rollers 12, 13 supporting a conveyor belt 11 in a conveyor belt unit 10 conveying a conveying object X by the conveyor belt 11; a detector 33 to detect the rotation failure of the support rollers 12, 13 based on a measured result by the main measurement parts 31; and an auxiliary measurement part 32 to measure at least one temperature among the temperature of the conveying object X and the temperature of an object to be detected heated by a heat generator at the outside of the conveyor belt unit 10. The detector 33 detects the rotation failure of the support rollers 12, 13 based on the measured results of the main measurement parts 31 and the auxiliary measurement part 32. |
