化纤高速纺丝机可移动试验位的研制

Development of movable test position on high-speed spinning machine

由于前纺原有POY、FDY生产线1台变频器控制6个位卷绕头不利于新品开发,通过移动试验位的研制,将卷绕头6位一起的"集中"调速改为可对生产线任何位卷绕头进行单独控制,控制柜可移动,其中包含3台变频器实现对摩擦辊、槽辊、卡盘3台电机的调速,1台PLC实现逻辑控制功能。控制柜改造后,不改变工艺,保留原来的操作习惯,从而为单品种、小批量新品开发生产提供了可能。通过近3年的投入运行,为公司开发出了多个纤维产品,经济效益十分显著。

On former POYFDY production lines one inverter controls six winders,which is not good for process adjustment and new product development.Instead of six winders being controlled together,with movable test positions,any single winder could be separately controlled.The control cabinet is movable,motor speed of friction roller,cam and chuck could be controlled by three inverters,one PLC realizing logical control function.In addition, the production process and former operating modes remain unchanged.In this way,trialing single and small quantity products becomes feasible.Since the movable test positions being put into use for nearly three years,many new polyester yarns with various specifications have been developed,achieving high economic benefits.
