Development of electronic shedding system of three-dimensional loom

According to the special requirements to shedding mechanism for weaving three-dimensional fabric,a new electronic shedding system is developed to form the clear multi-shed with multi-layer warp which is controlled by PLC and driven by servo motor. This method has simplified the shedding mechanism and improved the flexibility and reliability of the shedding mechanism. It is introduced that the general design of three-dimensional loom's shedding system,including the driving system's hardware configure and its software's controlling principle. Transient dynamic responses of 3-D loom's heald frame driven by three kinds of movement laws are analyzed,and it is concluded that sine acceleration motion is the ideal movement for the electronic shedding system of 3-D loom. The new shedding system has been applied in a three-dimensional loom prototype successfully.
