PURPOSE:To improve a quality control in case of packing by analyzing whether two kinds of metallic and non-metallic objects being in the inside of an object to be detected moving at a constant speed exist or not by making them contact by pressing to plural detecting ends for detecting a prescribed detecting distance. CONSTITUTION:A titled device is constituted of a transfer means 9 for feeding out an object 1 to be detected, a detecting means 4 for detecting whether a metallic object 3 and a non-metallic object 2 in the object to be detected 1 exist or not, an encoder 19, a converting means 7 and a removing means 8. Also, the detecting means 4 is provided with two detecting ends 5 for detecting a thickness of the non-metallic object 2 and a prescribed detecting distance. A converting means 6 executes a control so as to send out a pulse signal from the encoder 19 to a control means 7 only in case a signal from the detecting end 5 is satisfied, and also sends out a signal of removal to the removing means 7 in case a pulse count corresponding to a length 12 and 13 of the object 2 and 3 to be detected is not obtained. |
