Servo motor-based electronic shedding mechanism

To improve the working efficiency of loom and accelerate the renovation speed of fabric varieties,this paper demonstrates the servo motor-based electronic shedding mechanism.It introduces the principle,hardware and software of this electronic shedding mechanism.There are 16 harnesses in this mechanism.Each piece is driven by a separated servo driving system.Based on the idea of modular design,the function of lifting heddle is realized through programming in the PLC.The function of harnesses selection is realized by PLC′s IO which can control the servo motor′s state.Besides,the flow chart of control system is given.The paper also introduces the method as how to transfer the gray code from the photoelectric encoder to natural binary code and has finished the design of whole servo motor-based electronic shedding mechanism.
