A winding forming control method for real-time detection and dynamic tension adjustment

Abstract

The invention discloses a winding forming control method for real-time detection and dynamic tension adjustment, the steps of which are as follows: 1. The winding start-up stage. The overfeed wheel starts to rotate, and after a delay the yarn core starts to rotate. The overfeed wheel performs uniform acceleration motion. Calculate the target rotational speed of the yarn core according to the rotational speed of the overfeeding wheel; drive the rotational speed of the yarn core to dynamically pursue the target rotational speed. Second, the smooth operation stage. Dynamically adjust the target tension of the yarn roll with the winding of the yarn roll; when the linear speed of the yarn roll remains constant, dynamically calculate and update the target speed of the overfeed wheel according to the change of the target tension F, and drive the speed dynamics of the overfeed wheel Chase the target RPM. Three, the machine stop stage. The yarn core moves at a uniform deceleration, and the overfeeding wheel starts to decelerate after a delay. Calculate and update the target rotational speed of the overfeeding wheel according to the change of the rotational speed of the yarn core; drive the rotational speed of the overfeeding wheel to dynamically chase the target rotational speed. Through the precise adjustment of the tension of the yarn, the present invention makes the bobbins evenly wound, free from yarn breakage and less yarn defects.

Description

technical field [0001] The invention belongs to the technical field of textiles, and in particular relates to a winding forming control method for real-time detection and dynamic tension adjustment. Background technique [0002] In the textile industry, improving the quality of yarn winding is an important measure to improve the quality of textiles, and tension is the key to affecting yarn winding. Yarn tension not only affects the winding density and shape of the package, but also affects the evenness of the yarn, which directly affects the production of downstream processes and fabric quality. If the yarn tension is too small, the yarn traction force will be insufficient, causing problems such as yarn doffing and edge collapse; if the yarn tension is too high, the yarn hairiness will increase, and even yarn breakage will occur. It can be seen that tension is one of the key factors in the yarn winding process. [0003] In order to better control the yarn tension in the wi...
