| Summary: | 碩士 === 國立臺北科技大學 === 機電整合研究所 === 100 === The flying shear machines are commonly used in manufacturing automation. Similarity mechanisms are also used in continuous processes, such as automatic filling machines. The purpose of this research is focused on this kind of mechanism, to analyze and plan its motion, and then to develop a motion controller for industries.
At beginning, the relationship between rotary angle and feeding of cutting zone is established. Using the boundary conditions and desired cutting length, a 5th order polynomial is formulated to fit the non-cutting zone. Thus, its position, speed and acceleration are continuous with cutting zone.
In the implementation, motion type PLC is selected as the controller. First we write a MATLAB program to calculate the relationship between feed and cutting wheel’s position, and then the calculated results of the program is downloaded to PLC and electronic CAM.
To prove the method, various cutting lengths, radius of flying wheel and work angles, the controller are capable to finish the settings and thus have reached the goal that we hope as proposed. In addition, our research can make many rollers to work with feed at the same time. Thus, it would reduce the expenditure of the industries.
