交流伺服系统在复卷机设计中的应用

Application of AC Servo System in Rewinder Design

针对部分复卷机控制系统设备混杂导致的设备兼容性低、维护费用高及间接张力控制等问题,设计了一套新的交流伺服系统,并加入直接张力控制,通过复合张力控制来实现纸卷张力实时控制;结合退卷机机械结构图,介绍了恒张力退卷原理;采用新的交流伺服系统可对上下复卷辊进行负荷分配控制,实现上下复卷辊输出转矩的控制及确保驱动力输出的稳定,从而保障复卷机构的安全运行;实际运行结果表明,交流伺服系统的稳定性良好。

In this paper,a new set of AC servo system was designed and direct tension control was added into the system,using compound tension control to implement the system′s real-time tension control,in order to solve the low compatibility,high maintenance cost and indirect tension control problems caused by the miscellaneous equipment in some rewinder control system.Combined with mechanical configuration diagram of the unwinding,the principle of constant tension unwinding was introduced.The Load distribution method was applied to the upper and lower rewinding rollers to realize the control of the output torque of the upper and lower rewinding rollers to ensure the stability of the driving force output and ensure the safe operation of the rewinding mechanism.The system performance and stability was verified in the actual operation.
