Application of PLC/Converter Technology to Steel Tube Head-tail Alignment and Separation Operation

摘要: 利用PLC及變頻器技術(shù)，研發(fā)一套不同直徑和長度的鋼管在規(guī)定距離6 m內(nèi)平穩(wěn)對接和分離的輸送輥道控制系統(tǒng)。該輸送輥道控制系統(tǒng)能在進(jìn)料輥道與主機機頭相距6 m的位置，實現(xiàn)管與管的迅速首尾對接，且撞擊程度??；前一根鋼管管尾出探傷平臺后，前后鋼管首尾迅速脫離，順利實現(xiàn)單根下料；管尾對接、分離后輸送輥道速度與探傷速度相同，保證了探傷精度。

Abstract: Developed with the PLC/Converter Technology is a roller table control system capable of getting steel tube stably head-tail aligned and separated within a specified 6-meter distance.Specifically speaking,this very control system can realize the operation of quick head-tail alignment of tubes with slight bumping at a position on the roller table with a 6-meter distance to the head of the main machine.As soon the tail end of the first tube runs out of the detector platform,the tail end of the first tube and the head-end of the second one are separated quickly so as to bring about single-piece discharge operation.And then the speed of the roller table keeps the same as that of the detecting machine in order to ensure the flaw detection precision.
