Control Method of Pattern Loading For High Speed Double Needle Bar Warp Knitting Machine

Abstract

The disclosure discloses a control method of pattern loading for a high speed double needle bar warp knitting machine, and belongs to the technical field of warp knitting equipment. Through disposing two or more than two high speed FIFO pattern data cache regions on a shog controller, a data read-write conversion function of each cache region continuously and automatically is respectively realized. According to a current position of each guide bar, a target position of current shogging of an original pattern and a starting course position of a novel pattern, a control system of the double needle bar warp knitting machine automatically calculates a shogging displacement required by each guide bar in a pattern loading process, and sends out instruction information to a shog driving execution unit corresponding to each guide bar. In a respective underlapping interval allowed of each guide bar, the corresponding guide bar is respectively driven by the shog driving execution unit to respectively and precisely move to the starting course position of the novel pattern to complete the electronic shogging pattern loading. Needle collision caused by guide bar shogging during pattern loading is avoided. Pattern loading steps of the double needle bar warp knitting machine are simplified; the work intensity is reduced; and the work reliability is improved.
