A control realization method of pattern loading on high-speed double needle bed warp knitting machine

Abstract

The invention discloses a method for realizing pattern loading control of a high-speed double-needle bed warp knitting machine, which belongs to the technical field of warp knitting equipment. By setting two or more high-speed FIFO pattern data buffer areas in the traversing controller, the data continuous reading and writing automatic conversion function of each buffer area is respectively realized. The moving target position and the starting row position of the new pattern, the double-needle bed warp knitting machine control system automatically calculates the required traverse displacement of each bar during the loading process of the pattern, and reports to the corresponding position of each bar The traversing drive execution unit sends out instruction information, and the traversing drive execution unit respectively drives the corresponding bars to move accurately to the initial row position of the new pattern within the allowable range of the respective needle back traversing of each bar to complete the electronic pattern. Traversing pattern loading avoids needle strikes caused by bar traversing during pattern loading, simplifies the pattern loading steps of double-needle bed warp knitting machines, reduces labor intensity, and improves work reliability.

Description

Technical field [0001] The invention relates to a method for realizing pattern loading of a high-speed double needle bed warp knitting machine, which belongs to the technical field of warp knitting equipment. Background technique [0002] There are two types of loop-forming motion modes of the double-needle bed warp knitting machine: ordinary type and high-speed type. Among them, during the loop forming process of the ordinary double-needle bed warp knitting machine, the front and back needle beds alternately rise, that is, the entire process of rising and unwinding, laying yarn, lowering and closing, and loop forming on the front needle bed. The middle and rear needle beds are always at the lowest position, and the front needle bed is always at the lowest position during the entire process of the rear needle bed ascending and descending to form loops; when the current and rear two needle beds are both in the lower loop forming section, new The loading of the pattern makes the b...

Problems solved by technology

[0006] In order to solve the cumbersome operation of the existing double-needle bed warp knitting machine pattern loading, the transmission mechanism of the rear needle bed needs to be removed frequently, which greatly increases the operational difficulty and labor intensity of the double needle bed warp knitting machine. Problem, the present invention provides a high-speed double-needle bed warp knitting machine pattern loading control method, first according to the current position of each bar, the target position of the original pattern this time, and the start of the new pattern The row position, the system automatically calculates the required lateral movement displacement of each bar during the pattern loading process, and sends instruction information to the corresponding lateral movement drive execution unit of each bar, and the respective needles of each bar Back traversing allows the section to be driven by the traversing drive execution unit to drive the corresponding bars to move precisely to the initial row position of the new pattern, to complete the loading of the new pattern, and to avoid possible problems caused by the swaying of the bars when the pattern is loaded. Needle collision, yarn breakage, broken needle and other phenomena, simplify the pattern loading steps of double needle bed warp knitting machine, reduce labor intensity and improve work reliability
