Design and Implementation of New Control System in PASSIM Filter Cigarette Maker

The original control system of PASSIM filter cigarette maker adopting logic control circuit board had the disadvantages of poor resistance to disturbance and frequent machine failures which resulted in low production efficiency,high material consumption and labor some maintenance works.Therefore,a new electric control system was designed,wherein PLC was used for process control,industrial computer was used as a host computer to implement man-machine communication,and AC servo was used for drive.Cigarette weight and quality monitoring were fulfilled by an exclusive high-speed signal processing system.The communication between different units was carried out by PROFIBUS,CAN and MPI.The improved PASSIM cigarette maker works stably,reliably and features high sampling speed,fast response and easy of maintenance;its operation efficiency raises from 85% to more than 90%;and the consumption of cigarette paper and cut tobacco is also reduced.
