PURPOSE:To improve the operability by providing reset means of a material tracking device for iron steel or the like, which is reset in response to a forward rotation signal of a down-stream table at the time of resetting a material tracking memory. CONSTITUTION:When material passes through a detector without detection, the detector is adapted to chatter, and a material existence tracking memory 10 is again set. In this case, as a downstream table 6 is turned forward, a forward rotation signal 14 is input to AND gate 18 through OR gate 20 and the material existence memory 10 is reset by an output of the AND gate 18. Thus, automatic operation can be performed smoothly to improve the operability. |
