Wire system is one of the key systems of welding wire production，its control performance directly affects the quality of welding wire.Current row winders row silk with zero angle,reliability is low.From point of view of convenient and practical,a set of automatic wire arranging system was designed.In the whole system,Siemens S7200 series programmable controller was as the control core.The hardware was designed,and the simulation model of the whole system was built.The simulation results show that the designed automatic wire discharging system can be used to realize high precision automatic wire array.
