Abstract:

Facing the problems such as low automation, high labor intensity and high labor cost associated with traditional manual cylinder changing, a new automatic cylinder changing scheme based on truss robot and bobbin changing manipulator was proposed. According to the bionic technology of manual changing the bobbin, the mechanical structure of the truss robot and the bobbin changing manipulator was designed and a laboratory testing machine was developed, taking in to considerations of the factors such as the layout of the production workshop, the structure of the bobbin, the type of the bobbin and the changing period, the process flow and the electrical principle diagram of the automatic bobbin changing. The control algorithm of bobbin change based on AS320T module and servo motor was established, and the function of automatic bobbin change was achieved by using a touch-screen as man-machine interface. The research results show that the control technology can meet the requirements on precision, stability and repeatability of the automatic bobbin changing of the circular weft knitting machine, and realize the function of "automatic bobbin changing with manual thread joining" for the circular weft knitting machine, which is significant in solving the problems in traditional manual bobbin changing.

Key words: circular weft knitting machine, automatic bobbin changing, bobbin holder, bobbin, truss robot, bobbin changing manipulator
