BF公司L6生产线快速换型效率改善分析

针对BF公司L6生产线快速换型流程中的换料效率低、预装工位待料频繁问题,基于精益生产思想中的快速换型理论,采用价值流图析、意大利面条图等方法,通过设计工位物料清单来缩减换料时间,提升换料效率;通过设计换型信息提示灯来优化换型信息流;通过设计新的料架,减少工序调整的换型时间,并对现有快速换型流程进行优化,使整个换型效率得到很大提升。L6生产线评价结果显示,采用新的方法,不同系列产品175D0、38100的换型时间从17.9min缩减至6.2 min,换型效率提升了65.4%。

Research on the Efficiency Improvement of SMED in BF's Production Line

Aim at the problems in the L6 production line of BF company such as the low efficiency of refueling and the frequent replacement of the pre-installed station, based on the theory of SMED in lean production, by using the value stream mapping, spaghetti diagram method, the change type information lamp is designed to optimize the change information flow. Through the design of new material rack, the changeover time of process adjustment is reduced. And through the optimization of the existing SMED process, the whole change efficiency has been greatly improved. L6 production line evaluation results show that by using new methods, the changeover time of different series products such as 175D0 and 38100 is reduced from 17. 9min to 6. 2 min, and the transfer efficiency is increased by 65. 4%.
