Design And Research Of Carpet Tufting Machine Pattern Transverse Mechanism

The realization of the pattern transverse of carpet tufting machine will enrich carpet patterns, and these technologies have a very important meaning of carpet tufting technology's development in the long run and will have an excellent prospect.Pattern laterally of carpet tufting machine was realized by driven needle bar shifting means. Moreover, the shifting of needle bar could realize by cam driven mechanisms. In this dissertation, the mechanical cam transverse method and the electronic cam transverse method were researched. And have a discussion on the design of the transmission structure of mechanical cam pattern transverse system as well as the design of equal diameter cam outline curve automatic created software. Furthermore, finished the design of the electronic pattern controlling system, which is as PMAC motion controller as the control core, supported by industrial computer, and based on Fuji servo motor as the driver.(1) Through the research of the pattern transverse theory of the carpet tufting machine, design the general scheme of the two type pattern transverse methods.(2) The transmission mechanisms of the mechanical cam pattern transverse system adopt chain wheel to reducer to equal diameter cam to needle bar means. Then basis the analysis of shifting request of carpet patterns, use mathematic method set up the mathematic model of equal diameter cam. Design the equal diameter cam outline curve automatic created software basis this mathematic model. This software possess the function of automatic create equal diameter cam outline curve basis the input patterns.(3) Finish the selection calculation of servo motor, ball bearing screw and motion controller of electronic pattern transverse system basis on the research the theory of use electronic cam realize pattern laterally and the control request. Meanwhile, have an analysis of the hardware components of the electronic cam pattern transverse system and design the controlling software of the system. Illustrated the debugging method of PMAC motion controller and electronic cam pattern transverse system. Get the debugging and testing data of the system, and this data proves the stability and feasibility of the system.
