Förstudie och utveckling av styrsystem för lådförslutare

Sammanfattning: Ecolean Development AB are developing and manufacturing filling machines for pasteurized liquid food products. Because of lack of any appropriate supplier of box closer which seals boxes with small flaps, they have decided to start a project to develop a prototype of a box closer. Due to long experience from industrial automation I have been given a chance to develop control system for a box closer. Degree thesis involves electric design in ELPROCAD ic PRO and programming of PLC (programmable logic controller) and HMI (Human Machine Interface). The report describes degree project from the project plan phase via the development phase to the conclusions. Sometimes by mixing feelings with technical terms and explanations, I tried to describe challenges that I have been facing throughout whole degree project. My intention was to write the instructive and interesting report which will hopefully be appreciated by future readers. Keywords: PLC, Industrial Automation, Frequency Inverters, Control System, Programming
