| Paper registering is an important part in the printing process. Only if there is enough registering time, register system can register accurately, further assure registration accuracy among papers and colors to enhance the quality of presswork. New type paper registering system offers us a new solution to ensure sufficient paper registering time. In new system paper can register in side guide dynamically in the feeding process to conciliate abundant time for lay guide registering. The system controls papers through Step motor and running in wheel and the mechanism can be easy to realize.The main works are as follows:(1) Analyze and design the process of new type paper registering system.(2) Analyze startup characteristic of the Step motor, ameliorate startup curve, and develop the design software of speedup and slowdown.(3) Simulate and design the Step motor driving to apply a hardware situation for new type paper registering system.(4) Develop the main control system of Step motor.(5) Experiment. Test Step motor control rule of paper registering on the controller and driving system.The research of paper registering time in printing press have been progressed and applied in sheet-fed offset press of KBA and Heidelberg in a certain extent. The aim of research is enhancing the level and grade of homemade printing press for shortening the gap. This project is rare researched in our country and applied state patent. printing press; registering system; Step motor driving...
