Innovative Practice of"Three-in-one"Working Method for Zinser R71 Spinning Frame
In order to solve the problems of delayed doffing,waiting for replacing yarn and une-ven broken ends during large yarn of Zinser R71 spinning frame in the initial stage of trial pro-duction,resulting in many broken doffing ends,heavy workload of threading,many empty spin-dles and low efficiency,Zinser R71 spinning frame performance and process flow are analyzed.In view of the problems existing in trial production,from the aspects of"fast,detail,accurate,uniform and precise",the innovative working method of implementing roving pagoda segment on Zinser R71 spinning frame to realize the"three-in-one"of operating,doffing and replacing yarn are explored,and operation key points and innovative results are described in detail.Through the calculation of economic benefits,it is pointed out that the efficiency of the spinning frame is increased from 96.3% to 98% ,the production increase is 1.7% ,the process of doffing and replacing yarn are moved,the quota of the operator operating is reduced by 1/3,40 spinning frames are reduced by 30 workers,and the characteristics of the new equipment such as high speed,high efficiency and high quality are fully brought into play by using the"three-in-one"working method.
