Method for winding yarns

Abstract

The invention relates to a method for winding yarns. The method is implemented by a winding device, wherein the winding device drives a synchronous belt and a yarn guide connected with the synchronous belt to do transverse high-speed reciprocating motion through a control motor and drives a yarn roll to do longitudinal rotation through a winding motor; through the composition of the two motions, the yarn is wound on the surface of the yarn roll in a shape of spiral line; an acceleration time and a deceleration time of the control motor moving on the end part are set according to the diameter of the yarn roll at the end part of the yarn roll; and according to the acceleration time and the deceleration time, the speed of the yarn guide is controlled on the end part of the yarn roll so as to make the acceleration of the yarn guide constant and effectively avoid doffing.

Description

technical field [0001] The invention relates to a yarn winding method, in particular to a yarn winding method using bobbins and yarn guides for yarn winding. Background technique [0002] The winding method of yarn commonly used at present adopts following device to realize: [0003] Taking single-spindle control as an example, the stepping motor is connected to a yarn guide wheel, and the yarn guide wheel and the synchronous belt drive the yarn guide to move left and right through the positive and negative rotation of the stepping motor to realize the horizontal movement of the yarn; the winding motor The rotation drives the bobbin close to it to realize the winding motion. After the above two motions are synthesized, the yarn is wound back and forth on the surface of the bobbin in the shape of a helix. Wherein, the yarn guide is used for guiding the yarn through its own reciprocating motion and winding it on the surface of the bobbin more uniformly. [0004] However, as ...

Problems solved by technology

[0004] However, as the yarn winding becomes more and more high-speed, it is difficult to keep the acceleration of the yarn guide constant under the condition of high-speed winding, so that the synchronization between the movement of the yarn guide and the movement of the bobbin is prone to deviation, and the yarn It falls off from the surface of the bobbin without being tightly wound. This phenomenon is called doffing

The occurrence of doffing will produce defective products and cause production stoppage, affecting production efficiency
