Problems solved by technology

The control structure of this method is simple, but when one motor or two motors are disturbed or the speed fluctuates at the same time, the other motor cannot make corresponding adjustments in time, resulting in a sudden change in the winding ratio and affecting the package of the cross-wrapped bobbin. Density and density uniformity, reducing cross-wrap package quality and even affecting unwinding performance

Abstract

The invention discloses an electronic reciprocating cross-winding system speed cooperative control method. The above method not only includes the closed-loop control of the speed of the winding motor and the traverse motor, but also includes the synchronous closed-loop control of the speed of the winding motor and the traverse motor. The rotational speed of the orbiting motor and the rotational speed of the traverse motor have good dynamic followability and also have excellent overall synchronization performance. Compared with the existing technology, it solves the problem that the winding ratio will change suddenly when the winding motor and / or traverse motor is disturbed or the speed fluctuates, so that the winding of a certain stage of precision winding or graded precision winding Ratio remains constant during the winding process of the cross-packed bobbin, increasing the packing density of the cross-packed bobbin, significantly improving the density uniformity of the bobbin, improving the quality of the cross-packed bobbin and high-speed unwinding performance, and improving the operation stability of the winding equipment It has important practical application value.

Description

technical field [0001] The invention relates to a yarn guiding control technology in the textile field, in particular to a speed cooperative control method of an electronic reciprocating cross-winding system. Background technique [0002] Cross winding includes random winding, precision winding and graded precision winding. During the random winding process, the ratio of the reciprocating speed of the yarn to the circumferential speed of the cross-winding bobbin remains unchanged, that is, the winding angle remains unchanged, and the winding ratio (the ratio of the reciprocating speed of the cross-winding bobbin per minute to the reciprocating times of the traverse guide ) decreases with the increase of the diameter of the bobbin, and yarn overlap will occur during the winding process, which affects the unwinding of the bobbin; the winding ratio remains unchanged during the precision winding process, and the winding angle increases with the diameter of the cross-winding bobb...
