目的 以袋式包装生产线为对象，设计一条全自动袋式包装柔性生产线。方法 将包装生产线划分为料仓、定量下料装置、包装材料放卷装置、真空热封合装置、切分装置、放袋装置、自动计数器、PLC程序控制及人机界面，并对各装置进行柔性化设计。结果 形成了一条全自动袋式包装柔性生产线，并运用可靠性预计方法得出生产线的平均无故障工作时间为1164 h，满足实际生产需求。结论 该生产线具有较强的灵活性和节约性，对缩短产品生产周期、降低生产成本、快速响应客户需求、实现敏捷生产具有重要的意义。

The work aims to design a fully flexible automatic packaging production line for bag packaging. The bag packaging production line was divided into silo, quantitative feeding device, unwinding device of packaging material, vacuum heat-sealing device, segmentation device, unreeling device, automatic counter, PLC program control and human-machine interface. Flexible design was conducted for all the devices. An automatic production line was finally worked out. The average mean time between failures 1164 h was calculated by reliability prediction. It showed that the production line could meet the actual production demand. In conclusion, the production line has a strong flexibility and frugality. It is of great significance to shorten the production cycle, reduce production costs, rapidly response to customer demand, and achieve agile production.
