Embodiment Construction

[0018] The present invention will be further described below in conjunction with drawings and embodiments.

[0019] Such as figure 1 , in the automatic deviation correction control system, when the strip deviates from the center position of the unit during the transmission process, the CCD photoelectric detection device detects the real-time point information of the corresponding strip edge, and sends the point information to the single chip computer through RS-485 for processing , Calculate the actual deviation displacement of the strip, process the calculated deviation displacement through the PID algorithm, and send the deviation correction signal to the electro-hydraulic servo system through DIA conversion, and drive the deviation correction roller through the oil cylinder to perform deviation correction, thus forming a closed-loop control system.

[0020] Such as figure 2 , The A / D conversion pre-signal processing circuit uses an operational amplifier as a voltage foll...

Abstract

An automatic correction control system for strips is suitable for the field of production and manufacturing. The automatic correction control system is mainly composed of an A / D conversion front signal processing circuit, a current signal processing circuit and an RS-485 communication circuit. The control system is composed of a CCD photoelectric detection device, a displacement sensor, a correction controller, an electro-hydraulic servo control system and the like. The electro-hydraulic servo control system is composed of a servo amplifier, a servo valve, an oil cylinder, an oil source and the like. By the adoption of the system, a single chip microcomputer development system is adopted, the accuracy of a conversion circuit is improved, the cost is reduced, it is guaranteed that the automatic correction control system accurately and intelligently operates in real time, the response speed is increased, the system operates stably, the high anti-interference and reliability are achieved,and regular material winding and slitting in the production process can be guaranteed.

Description

technical field [0001] The invention relates to an automatic deviation correction control system for strips, which is suitable for the field of production and manufacturing. Background technique [0002] Strip deviation means that in the production line of the winding system (such as paper making, coating machine, slitting machine, plastic printing, film, rolling steel, etc.), the winding material is in the process of movement, and the winding is not neat due to the reason of the front. Or the deviation of the guide rollers in the unit, vibration, mechanical error, and changes in the tension of the strip may cause the deviation of the winding material, resulting in the deviation of the strip. [0003] In the continuous production process of cold-rolled strip steel (including subsequent treatment process), with the increase of unit speed year by year and the improvement of equipment processing technology, the produced strip steel becomes wider and thinner. In order to meet t...
