提出了一个具有固定在制品拉式机制（CONWIP） 的自动包装线控制方案。讨论了自动包装线实现这种拉式机制所面临的问题，给出了采用PLC、传感器和工业组态技术的实施方法。通过某企业自动包装线实际应用，验证了这种方案的可行和高效。

Control scheme of automatic packaging line with CONWIP (Constant Work-in-process) pull mechanism was put forward. Problems faced when using CONWIP mechanism in automatic packaging line were discussed. An implementation method using PLC, sensors, and industrial configuration technology was put forward. It was proved with practical application that this scheme is feasible and efficient.
