叙述了一种袋装机的设计与实现，详细分析了可编程控制器在袋装机中的应用方式及特点，利用FX2N-32MR对袋装机进行控制,详细讨论了袋装机的输入输出信息，研究了其逻辑关系。实际应用表明:系统获得了良好的控制效果，实现了袋装机全自动计量混合包装的控制目的。

The design and implementation of a bagging machine was introduced. The application mode and characteristic of programmable logic controller (PLC) in bagging machine was analyzed, which used FX2N-32MR as controller. The input and output information of the bagging machine was discussed and logic relation of the bagging machine studied. Practical application showed that the system has good control result, which real1zed the control purpose of auto automatic measuring mixing packaging.
