Abstract

This paper describes the design and implementation of a wrapping process using multiple sensors. The wrapper wraps a product of cylindrical shape such as rolled and wrap it with quality which guarantees safe protection of the wrapped product against ware and time over long period of transportation and storage. Also, it is required to avoid the damage of the product during the wrapping process and to provide safe and convenient human machine interface. To meet these requirements, the wrapping process includes many kinds of sensors. The sensors are encoders, proximity switch, photo electric sensors, and tension meters. These sensors are included in the parts of head, ring lifter, top sheet feeder, conveyor, and load stabilizer of the machine. The controller detects the status of the wrapping process and the material to be wrapped through sensors and controls the overall process. The developed process wraps the material faster and produces better wrapping quality than the previous wrapping machines. To describe the above, this paper consists of the following chapters. The chapter 1 introduces the wrapping process. Chapter 2 describes and analyzes previous wrapping machine. Chapter 3 proposes and details the improved wrapping process which uses sensors for intelligent operation. Chapter 4 discusses the control flow of the process. This chapter shows how the sensor data are used for control of the process. Chapter 5 concludes the paper with discussions on the developed wrapping process and further research topics.
