Automation and Improved control of Bundle pusher : Automation control

Sammanfattning: Newspapers are often bundled and packet on pallets to secure transport. Packing thebundles on pallets are often done with an automatic palletizer. For reliable operation,the bundle needed to have a correct position and orientation on the infeed conveyor.Wrong orientation can happen when the bundle is pushed from conveyor to thepalletisers conveyor. The main to reasons is wrong timing that leads to rotation of thebundle and to high pushing force that leads to tumbled bundles. The goal of thisproject is to make a prototype of a system that automatically adapts the pressure andsignal when to push using two laser sensors. One sensor sends a digital signal if laserbreaks, the other measure distance, e.g. bundle hight. The software was developed onan Arduino Uno board, and two interface board was made for voltage levelconversions. The prototype system managed to change pressure for different bundlesizes and timed the pushing signal correctly.
