Device for preventing flaw detection and sorting of mixed steel and control method

According to the device for preventing flaw detection and sorting steel mixing and the control method, when the control system receives the flaw detection and sorting result, the signals that the corresponding material stirring arms permit to act and other material stirring arms forbid to act are sent out, the possibility that bars are conveyed to non-corresponding positions to act can be avoided, and the production efficiency is improved. And the command of forbidding the action of other material shifting arms can be released only by the signal generated by the corresponding sorting rack completion material detection element, so that the possibility that the corresponding material shifting arm has acted but the bar material is not shifted to the corresponding sorting rack can be avoided. And through two-way interlocking control, each bar material is ensured to be on the corresponding sorting rack. 本发明提供了一种防止探伤分选混钢装置及控制方法，在控制系统接收到探伤分选结果的同时，发出对应拨料臂允许动作及其他拨料臂禁止动作的信号，能够避免棒料输送到非相应的位置动作的可能，且只有对应分选台架完成料检测元件产生的信号方可解
