Automating Aircraft Painting Hanger By Using PLC Conceptual Design

ABSTRACT

Aircraft Painting process recovers from many problem associated with the entire painting activities , such like efficiency , cost , environmental factors, and risks to the painting labors (contaminations , fumes ,flammability , toxicity ) . This research is to provide conceptual design and implement optimum solution to the problems mentioned above by using the automation techniques (PLC tool) to devolve a first phase painting robot .Considering the use of sensors ( object sensors , proximity or collision avoidance system) and actuators (DC servo driver to provide motions) plus some control devices( limit switches) .All these part encapsulated in a mechanism containing two spray guns fitted in a spray board with the sensors and actuators moving in the three dimensions around the aircraft sides. The control of this mechanism is achieved by using the Programmable Logic Control PLC SIEMENS S7-200 micro automation products using ladder diagram, to control motions in both spray board and the holding arm.
