Abstract : This paper describes the structure, principle, and implementation of the developed automatic radial tire winding system. The system uses a PLC as the main control device and a touch screen as the interface for system observation and control. A frequency converter controls the operating speed of the winding and traction motors, and a servo controller controls the wire arrangement function during the winding process. This system achieves rapid and precise radial tire winding, and can wind different types and specifications of cross-sections as needed. The system has been manufactured into a product, exhibits good performance in actual operation, and is currently in use. Keywords : Radial tire winding, PLC, Touch screen, Frequency converter, Servo controller. Currently, tires can be classified into bias-ply tires and radial tires according to their structure. Radial tires have better flexibility, can adapt to irregular impacts on the road surface, and are durable. Their cord structure results in much less friction during vehicle operation compared to bias-ply tires, thus having a longer tread life and better fuel economy. Compared to bias-ply tires, radial tires also have better grip. Because radial tires have the above advantages compared to bias-ply tires, they are now widely used in passenger cars, and this is also an important direction for tire development. Currently, most radial tire production lines in China are imported from abroad, which is very expensive. Domestically developed radial tire production lines are still in their infancy. As a key designer, the author developed an automatic winding system for radial tires, hoping to provide a reference for the independent development of radial tire production systems in my country. Winding is a crucial step in the radial tire manufacturing process, requiring the processed metal wire to be wound onto the surface of the steel rim into different cross-sectional shapes and specifications. In this design, a PLC serves as the main control device to uniformly schedule the operation of each component, and a frequency converter is used to control the speed of the traction motor and winding motor. To achieve different shapes and specifications of cross-sections during the wire arrangement process, a servo motor is used to control the position of each winding turn. Corresponding wire arrangement programs are programmed for the servo motors to meet different winding process requirements. For easy observation and control of the system, a touch screen is used as the main interface for system observation and control. Through the touch screen, not only can the current operating status of the system be observed, but also the transmission of different winding process data and the control of the automatic winding system can be completed. The system can be debugged online through real-time communication between the PLC and the touch screen, the PLC and the servo motor, and the PLC and the host PC. Regarding the control cabinet design, due to the large number of controllers and their different voltage levels, a dual control cabinet was adopted. The system has been debugged and is performing well; it is now in use. [b][align=center]For more details, please click: Development of an Automatic Radial Tire Winding System[/align][/b]
