The Study Of LY Combine Harvester Assembly Line Balancing

With the proposal of Made in China 2025 strategy,agricultural machinery and equipment industry benefits favorable policies.As an agricultural great power,the universal application of farm machinery and equipment is an important guarantee for the development of agriculture.LY company is a newly established enterprise,which is committed to agricultural machinery and equipment manufacturing and its combine harvester has a stable performance with a high quality.With the development of the company and market demand,the current mode of assembly and production will not meet orders in the future.The company has a serious difficulty in its assembly line,it has a giant diversity of workload and work time between every work station.Let alone long idle time,disorder in assembly process,low balance rate of general assembly line.Thus improve the balance of is the current object to the company.In this article,we will use assembly line balance theory and IE method to improve LY company's assembly line,in order to raise its balance rate.The first chapter of this paper first introduces the capability of industrial engineering methods to improve the feasibility of assembly line balance,summarizes on the assembly line balance improvement methods and results of research domestic and abroad,the research content,the research methods and technical framework.The second chapter introduces the evaluation index before and after the research the problem of assembly line balance of some basic concepts and the assembly line improvement.Then focuses on the analysis in this paper will use the method of motion analysis procedures,operation method,contents and steps,the demonstration research for the subsequent improvement of the assembly line balance.The third chapter is the analysis of the present situation of LY company,points out the existing problems in the product assembly process as The threshing rack assembly time is long,can not be timely supply of assembly line production.Each station take time gap,the idle time is too long,the unreasonable process arrangement.With the reasonable material storage.The fourth chapter studied the existing problems.Combining methods study and work measurement techniques,reduced the operation process,simplify the unreasonable assembly action,and innovate the production mode.Use proplanner a process simulation software to rearrange process and merge work station.Material management is optimized by the material label card,warehouse layout,etc.Using the assembly balance rate,idle time,exponential smoothing and balance delay indicators to evaluate balance improved assembly line.The fifth chapter of this article are summarized,and put forward the corresponding opinions and Suggestions.
