Application of Infrared Sensors to Improve Safety in Saw Mill

Abstract— Wood is natural organic material which is obtained from tree stem; it is used for various purpose, and sawmill is the place where wood is brought into required shape and size, with the help of rotating saw blades. Worker’s during giving feed to the saw blade, accidents are prone to occur, if their hands are moving near the saw blade, which may result in hand amputation, and to avoid the consequence this design of saw blade assembly which include IR sensors comes handy and increases safety, these sensors are placed near the saw blade, if unknowingly, worker’s hands come close to the blade while feeding wood, it recognises the human hand and stops the rotating saw blade immediately and avoids accidents.

Keywords— wood, sawmill, IR sensors, hazardous.

INTRODUCTION

Wood is the most common and natural organic material which plays very important role in our life, wood, which is brought to proper size and shape is used for various purpose like building automobile bodies, furniture’s, bridge construction, domestic constructions etc., and India is the place where we are still finding manual method to feed the wood to saw blade. And during the literature survey around Mangalore rural areas, we came to know that workers during giving feed to saw blades they have lost their hands, fingers and serious accidents had happened due to their negligence and due to this permanent damage on the body, they have to suffer till the end of their life. Even though many precautions has been taken to improve the Safety, but still it is very difficult to avoid accidents because most of the workers are uneducated and lacks skill. Even after proper instructions given by trained higher authority to workers, some workers fails to follow it, so we have adopted a new method to improve the safety by using infrared sensors. And in the future, if introduced in sawmills, workers will be having safety during working with the saw blade.
