Development Of The Visual And Monitoring System Of The Production Line For Massive Food Packaging

Stretch film packing machine is used to pack the massive food into packing bag,then pumpthe air in the bag for the vacuum degree, with the purpose of deoxidizing.This technology iswidely used in massive food packing area.At present, Stretch film packing machines are all withthe pattern of semi-automatic operating in China,and it is far behind the internationalstandard.Full-automatic production line for massive food packing is a kind of food packingproduction line which is with the processes of bag feeding,packing material measurementpacking material filling,vacuum forming,heat seal and packing into finishedproducts.Therefore,it is great practical value to develop the production line(which isfull-automatic) for massive food packing.This article is base on the production line for massivefood packing,and developing the visual and monitoring system on it to achieve full-automaticproducing.This system contains two sections:vision and monitoring.The main research contentis as follows:1. Determine the overall structure of the control system after analysis the technicalrequirements of the production line for massive food packing,and divide the controlling systeminto vision and monitoring section.2. Consider the functional requirement of the monitoring system,set up the hardwareconfiguration with the pattern of “touch screen&PLC”.Design the graphic interfaceconfiguration in the produce module as the core.Design the real-time database of the monitoredpoints base on thire characteristics.Develop the controlling circuit confuguration follow thecontrolling requirements of the monitouring system of the production line.Design the statementsconfigurations for the convenience of users.Design the monitoring system graphic interface ofthe production line using the touch screen as the hardware.3. According to the controlling characteristics of the pick-and-place manipulator, buildthe hardware structure using "IPC+PMAC card+servo drive and servo motor" model.Developthe controlling system which is based on the PWEIN software platform of the PMAC,so as toachieve the pbjective of kinematics inverse solution and pick-and-place positioning of themanipulator.4. Analysis the effect of the visual system of the pick-and-place manipulator,design thehardware system structure with the”CMOS camera+1394image capture card”model.Developimage detecting software system which is based on LabView and IMAQ Vision platform.Thissystem can achieve the porpuse of image collecting,distortion coorecting,median filtering andcanny edge detecting,so as to reach the extraction and identification of the image featureinformation of the massive food,and on the basis of complete block food in movement in theprocess of tracking process and positioning design. 5. Depend on the designment and development what are mentioned above,the experimentplatform of the pick-and-place manipulator is been built in this article.The experiment of theidentification of the massive food and pick-and-place of the manipulator has beenexperimentalized under the lab environment.The experiment show that the image processing canmeet the requirements in positional accuracy of massive food and control precision of themanipulator.
