基于单元化的“一个流”生产方式的应用分析

The Application Analysis of "One-Piece Flow" Cell Production Mode

以A公司壳体部件生产为例,将单元化生产与"一个流"生产方式相结合,设计单元化的班组模式。选择功能简单、小型化的生产设备,并将六轴成直线型排列,将清洗—碰焊—滚丝布置成U型布局,在六轴至清洗机之间采用输送带输送的传动方式,在清洗、碰焊和滚丝各工序之间分别使用提升机进行连接。在"一个流"单元生产中,需要同时考虑设备产能的平衡及单元化成员工作效率的平衡。"一个流"生产模式可减少在制品的存储数量,提高生产效率,但也面临在制品检测、小批量产品的换线换模、"多面手"的培养等问题,需在实践中进一步完善。

With the housing parts production of Company A as an example, combines unit production with one piece flow production and designs team unit mode. Chooses a simple miniaturized production equipment and puts six- axis in a line; Sets cleaning-welding-rolling equipments into a U-shaped layout; Uses conveyor belt transport between six- axis and cleaning machine and a hoist to link the process of cleaning-welding-rolling; In one piece flow production unit, considers the balance of the device productivity and the balance of unit members working efficiency. Though the produc- tion mode reduces the stock of semi-manufactured goods and improves production efficiency, it exists problems of work in process quality detecting, small lot production retooling and versatile workers cultivating, and it needs to be further improved in practice.
