Design of the Reverse Side Detection System for Packaging Paper of FOCKE350
FOCKE350 cannot detect and remove the reverse side of the trademark paper.Using a color detector,based on Siemens PLC programming methods,this work implements detection and removal of the reverse side of the trademark pa-per,as well as program shutdown,detector failure self-checking,and other functions.The retrofitted system only adds one detector on the basis of original detectors and detection phases,thereby facilitates saving wiring and input points.
