Steel coil uncoiling automatic locating auxiliary threading system and method

Abstract

The invention discloses a steel coil uncoiling automatic locating auxiliary threading system and method. According to the threading system, a position sensor is arranged on a piston rod of a swing guide plate hydraulic cylinder, and the swing guide plate hydraulic cylinder achieves stepless speed regulation through a proportion valve; and a photoelectric proximity switch is mounted at the front end of a telescopic guide plate. The threading method comprises the steps that after an inlet steel coil vehicle completes coil feeding successfully, an uncoiling machine is used for carrying out uncoiling threading; an uncoiling machine guide plate automatic locating subsystem calculates a swing guide plate swing target position coordinate, a piston rod stretching position and a telescopic guide plate stretching point target position coordinate according to a calculation model; the swing guide plate hydraulic cylinder carries out position locating; and after the telescopic guide plate stretchesin place, an uncoiling machine motor conveys out a belt head at crawling speed. According to the steel coil uncoiling automatic locating auxiliary threading system and method, by means of the uncoiling machine telescopic guide plate, a swing guide plate, a position sensor and the proximity switch, an uncoiling machine auxiliary guide plate threading mathematic model is established in a control system, and steel coil uncoiling automatic locating auxiliary threading is achieved.

Description

technical field [0001] The invention belongs to the technical field of control of iron and steel production lines, and relates to a steel coil uncoiling automatic positioning auxiliary belt threading system and method. Background technique [0002] In recent years, with the improvement of production efficiency and labor costs in the iron and steel industry, the steel production line has higher and higher requirements for automation. However, the diameter, weight and width of steel coils of different specifications in the steel production line are different, and the positioning of auxiliary equipment for belt threading is not the same. The position is also inconsistent, requiring manual adjustment of auxiliary belt threading equipment. Manually position the threading guide plate to the feeding position for auxiliary threading when threading the belt. If the positioning position is not suitable, it is necessary to manually adjust the positioning of the guide plate again, which...
