Yarn Tension PID Control of Air–Jet Texturing and Twisting Machine Using a Programmable Logic Controller (PLC)

This paper defines a PID type yarn tension control run by a PLC system that is used to control the yarn tension below the twisting head of the novel air jet texturing and twisting (AJT) machine. In the standard sequence of the AJT, if the yarn is transported to the twisting and winding head with a low tension value, the yarn is bound to wrap around the shoulder below the twisting head and break immediately afterwards. Additionally, when the yarn tension is high, the yarn is also şnevitable broken. Using the tension control, it is planned to stabilize the tension by controlling the transport cylinder motor with the help of the tension sensor and the S7300 type PLC.
