Application of transducer to layer winding machine pay-off

To introduce design and system control of layer winding machine in welding wire production, the requirement on pay-off are as follows： active pay-off, constant tension, running steadily, operation convenient, low failure rate. The con- trol solution and control principle diagram is given. The parameter setting and setting basis, process PID control principle and attention matters of sensor adjustment are introduced. Running result shows that the pay-off of system is steady, run- ning tension is constant, take-up speed reaching 20 m/s can meet requirements of production process.
