目的 改进旋转称量式灌装旋盖机的控制方法。方法 基于对市场上现有该类设备的研究，设计一种以工业无线局域网(IWLAN)通信方式代替电滑环的旋转称量式灌装设备，同时将称量传感器与称量模块分开进行设计。结果 实现旋转PLC与固定PLC的数据传输，既传输了大量的数据，又避免了因电滑环掉电而导致的数据传输中断，在保证灌装精度的同时大大降低了更换称量单元的成本。结论 该设备既保证了很高的灌装精度，同时具有很快的灌装速度，在实际应用中取得了很好的使用效果。

The work aims to improve the control method of rotary weighing filling-oriented capping machine. Based on the research on such existing equipment on the market, a kind of rotary weighing filling equipment was designed with industrial wireless local area network (IWLAN) communication mode instead of electric slip ring. In the meantime, the weighing sensor and weighing module would be separately designed. As for the data transmission of rotary and fixed PLCs, it not only realized the transmission of mass data, but also avoided the interruption of data transmission caused by power failure of electric slip ring. The cost of replacing the weighing units was greatly reduced while the filling precision was ensured. This equipment not only ensures the very high filling precision, but also has higher filling speed. In the actual application, excellent using effects have been achieved.
