Shaped steel transmission roll table automatic stopping device

The utility model provides a shaped steel transmission roll table automatic stopping device, including PLC and connected converter, at a set of transmit and receive for the correlation formula detection switch of shaped steel transmission roll table both sides installation, correlation formula detection switch is connected with PLC, adds roll table automatic stopping control module in the PLC, and roll table automatic stopping control module is continuous with PLC internal timing ware. The utility model discloses a delay control roller motor stall makes shaped steel slowly reach the roll table end with the state that freely parks, reduces and the striking inertia of spring stop the impact force of reduction shaped steel to effectively avoid the damage of spring stop, eliminate the mass defect that shaped steel leads to because of the tip striking. 本实用新型提供种型钢传输辊道自动停车装置，包括PLC及与其连接的变频器，在型钢传输辊道两侧安装组发射和接收用对射式检测开关，对射式检测开关与PLC连接，PLC内增设辊道自动停车控制模块，辊道自动停车控制模块与PLC内部定时器相连。本实用新型通过延时控制辊道电机停转，使型钢以自由停车的状态缓慢到达辊道末端，减少与弹簧挡板的撞击惯
