Stay-cord sensor based roller spacing measurement system and method

Abstract

The invention discloses a stay-cord sensor based roller spacing measurement system and method. The stay-cord sensor based roller spacing measurement system comprises a limit switch used for performing zero setting, a stay-cord sensor used for measuring the roller spacing, a field data acquisition and processing unit and a control system, and is characterized in that the limit switch is located at the side, which is adjacent to a roller, of a mechanical arm; the stay-cord sensor is located between the roller and the mechanical arm; the field data acquisition and processing unit is used for receiving output signals of the limit switch and the stay-cord sensor and performing data processing on the received signals; the control system is used for performing data interaction with the field data acquisition and processing unit and controlling a motor to operate; signal output terminals of the limit switch and the stay-cord sensor are respectively connected with an I / O port of the field data acquisition and processing unit; the control system comprises a salve station controller and a master station controller; the field data acquisition and processing unit performs data interaction with the master station controller through a PROFINET bus; and the slave station controller performs data interaction with the master station controller through the Ethernet / IP.

Description

Technical field [0001] The invention relates to the technical field of steel tube reshaping equipment, and in particular to a roll distance measurement system and method based on a drawstring sensor. Background technique [0002] Steel tube forming technology Before forming, the strip undergoes leveling, trimming, planing, surface cleaning and conveying, and pre-bending treatment. The weld gap control device is used to ensure that the weld gap meets the welding requirements, and the pipe diameter, the amount of misalignment and the weld gap are strictly controlled. [0003] However, under the current technical level, the degree of automation of the steel tube forming roll changing process is not high, and the entire mold changing process is completed manually with the help of measuring tools such as a ruler or purely manually. Not only after the changeover is completed, the steel pipe forming will inevitably have large errors, the accuracy requirements cannot be guaranteed, and a ...
