汽车座椅面套生产效率提升方法的探讨

Study on the Method to Improve the Production Effi ciency of Car Seat Cover

全球汽车行业自动化水平不断上升,而汽车座椅面套生产仍然属于人工劳动密集型产业。虽然某些特种工序也采用自动化缝纫设备进行加工,但是95%以上的工序必须采用人工完成转弯、翻转、开缝、卷边等多种复杂的缝纫工艺,才能将二维裁片缝合成立体结构,所以提升生产效率关键还是要从研究操作者作业着手。汽车座椅面套生产与服装行业有共同之处,又有独特之处,本文将以从汽车行业的视角对座椅面套缝纫生产进行的探讨,通过大量录制操作者的作业视频,对操作行为、人机工程等方面进行系统地分析研究,归纳总结出影响汽车座椅面套生产效率的八大客观要素和改进措施,以及主观要素对客观要素的影响。将最佳作业方式形成标准化应用于生产实际,使汽车座椅面套生产更加高品质高效率降低疲劳度,为企业精益生产和卓越运营提供有效方案。

Though the automation level of global automobile industry rises,and automated sewing equipment are adopted in some special processes in car seat trim production,to sew two-dimensional cutting pieces into three-dimensional structure,there are still more than 95%of the working procedures which need to go through a variety of complex sewing processes like turn,reverse,butterfl y cross seam and fold seam,etc.That makes car seat trim production an artifi cial labor-intensive industry,so the key to improve production effi ciency is to make a study of operator.Through large numbers of video recordings of operators’work,this paper systematically analyses aspects such as operation behaviors and ergonomics.Through horizontal benchmarking of diff erent operators who do the same process,this paper sums up the eight objective elements and improvement approaches which have infl uence on the effi ciency of car seat trim production,and the subjective factors’impacts on objective factors.The best operation practices are formed as standardized operations and are applied to production,which is helpful for car seat trim production with higher quality,higher effi ciency,and lower fatigue.
