Winding forming control method capable of detecting and dynamically adjusting tension in real time

Abstract

The invention discloses a winding forming control method capable of detecting and dynamically adjusting tension in real time. The winding forming control method capable of detecting and dynamically adjusting the tension in real time comprises the following steps: 1, a winding starting stage: an overfeeding wheel begins to rotate, and a yarn core begins to rotate after delay; the overfeeding wheel does uniformly accelerated motion; the target rotating speed of the yarn core is calculated according to the rotating speed of the overfeeding wheel; and the rotating speed of the yarn core is driven to dynamically follow the target rotating speed; 2, a stable operation stage: the target tension of a yarn roll is dynamically adjusted along with winding of a yarn roll; and under the state that the linear speed of the yarn roll is kept constant, the target rotating speed of the overfeeding wheel is dynamically calculated and updated according to the change of the target tension F, and the rotating speed of the overfeeding wheel is driven to dynamically follow the target rotating speed; and 3, a machine stopping stage: the yarn core does uniformly retarded motion, and after delay, the overfeeding wheel starts to retard; the target rotating speed of the overfeeding wheel is calculated and updated according to the rotating speed change of the yarn core; and the rotating speed of the overfeeding wheel is driven to dynamically follow the target rotating speed. According to the winding forming control method capable of detecting and dynamically adjusting the tension in real time provided by the invention, the tension of yarns is accurately adjusted, so that cheeses are uniformly wound, no yarn broken ends exist, and the number of yarn faults is small.

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...
