method of automatic control of flying shears for cutting the ends of rolled metal

摘要

A method of automatic control of flying shears for cutting the ends of rolled metal includes isolation of a section of moving of rolled metal, calculation of the speed of displacement of rolled metal, forecasting of displacement of the end of rolled metal in the moment of cutting, measurement of the speed of rotation of the drum of shears and their angular displacement, calculation of the difference between forecasted displacement of the front end of rolled metal and linear displacement of the blades of shears.
