Though the automation degree for lube-filled product line has made full development in Germany, Italian, America; It is still at the developing in our country. Based on the self-industry and the application of the other trade on auto-control technique. This paper advances the frame of the control, automatic technology is its kernel technology. It was developed by special technology such as mechanism, PLC etc. the paper first analyzed and established a whole set of ideas which ensured that the producing system has real producing ability as well as simplest structure. On the product line control system, the PLC has been used with. Owing to its high reliability, high stability, and easiness in programming and using, has been extensively used in the process control system of production line in the modern industry enterprises. Some levels have explained in detail and the goal and function of the whole automated conveyer system. The structure of the conveyer system is clearer, and the level of the conveyer system is demarcated more clear, The w
