A Coil Length Measuring Method at Coil Collection Station

Abstract

The invention discloses a coil length measurement method at a coil collecting station, which is used to solve the problem of inaccurate coil length measurement in the prior art. A method for measuring coil length at a coil collection station includes marking a first color-coded point at the position of a moving axis of a moving arm of a trolley, and marking a second color-coded point at the position of a moving axis of a fixed arm; the camera records the first color-coded point and the second color-coded point in real time. The movement of the color scale point; when the first color scale point no longer moves, the camera records the positions of the first color scale point and the second color scale point; for the first color scale point and the second color scale point Image processing is performed on the image of the position, and the number of pixels between the first color scale point and the second color scale point is calculated; according to the calculated pixel number combined with the proportional relationship between the pixel pitch size and the actual object pitch size, the obtained actual length of the coil. The coil collecting station control system provided by the invention solves the problem of inaccurate coil length measurement in the prior art.

Description

technical field [0001] The invention relates to the field of automatic control, in particular to a coil length measuring method at a coil collection station. Background technique [0002] In the prior art, the control of the high-speed wire coil collection station is realized by holding the steel coil tightly by the moving arm and the fixed arm of the trolley, transporting the coil to the C-shaped hook, unloading the coil after centering and positioning. Wherein, the distance between the initial position of the movable arm and the fixed arm when it is fully opened is a constant distance, and the length of the coil is obtained by subtracting the distance traveled by the movable arm to clamp the steel coil from the constant distance. The position of the trolley is positioned by the encoder. Measure the actual distance between the trolley and the centerline of the C-shaped hook when the trolley is in zero position, and subtract half the distance from the steel coil from the act...
