Design and Application of Packet Film Detection System for CH of GDX2 Packing Line

A packet film detection system for CH of GDX2 packing line was designed with photoelectric detection technology. By installing 5 optical fiber sensors on the turret of CH, when a packet not properly overwrapped was detected, PLC released a signal and that packet would be rejected at the rejecting station. The results of application showed that after installing packet film detection system, the number of cigarette packet with film-related defects reduced from 46 packets to zero per month, the rejection rate of cigarette packet with defective film wrapping reached 99.99%, the false rejecting rate was 0.001%, and the packing quality of cigarette was effectively improved.
