Loose type coning control method

Abstract

The invention relates to a method for controlling the loose bobbin winder, which can improve the winding quality when winding yarn. The inventive method comprises: preparation, calculating length and clear, hand-operated yarn up, starting, motor winding, automation, judgment, calculating the length and stopping when the tube is full, hand-operated get yarn, and finish. The invention can apply variable semi-automatic bobbin winder control.

Description

Technical field: [0001] The invention relates to a control method for winding filamentary material, especially a control method for winding material onto a bobbin. Background technique: [0002] Winding is the process of winding bobbins or bobbins into bobbins with a certain capacity in textile production, so as to facilitate the smooth progress of the next process (such as warping, weft winding, yarn-free loom drying or dyeing, etc.). Winding is the first process of the preparation process before weaving. The winding process is usually completed on a special machine (winding machine), and its corresponding control method (process flow) will directly affect the quality of the subsequent process; the winding process In the early days, most of them were completed by manual and mechanical control methods, and the corresponding equipment was a low-speed winder. There are many problems in the fixed length of the thread; with the advancement of textile technology, high-speed, sin...

[0002] Winding is the process of winding bobbins or bobbins into bobbins with a certain capacity in textile production, so as to facilitate the smooth progress of the next process (such as warping, weft winding, yarn-free loom drying or dyeing, etc.). Winding is the first process of the preparation process before weaving. The winding process is usually completed on a special machine (winding machine), and its corresponding control method (process flow) will directly affect the quality of the subsequent process; the winding process In the early days, most of them were completed by manual and mechanical control methods, and the corresponding equipment was a low-speed winder. There are many problems in the fixed length of the thread; with the advancement of textile technology, high-speed, single-machine drive and semi-automatic control methods are adopted to improve the production efficiency of winding operations and reduce energy consumption. It can adapt to a large extent. The production needs of the continuous improvement of the follow-up process technology, while the technical requirements for production control are not particularly strict, and the investment in production equipment will not be too large, so it can meet the needs of the development of the textile industry in vast regions of the world technically and economically. This control method has great market potential, but the existing winding semi-automatic control method also has the following problems: as its yarn fixed length usually adopts mechanical or electronic fixed length method, the mechanical fixed length control error may be more than 3%, The electronic fixed length adopts the angular displacement sensor. Although it has been improved, it still belongs to the normalized visual length measurement. However, the international semi-automatic method of yarn fixed length requires an error of ±1-2%, which is difficult to achieve with the existing control methods. To adapt to the development needs of the winding follow-up process after improving the production technology; another example is the requirements for the winding density of the bobbin. The current method is to periodically change the drum speed and adjust the pressure of the bobbin in terms of parameters. In terms of structure, design the groove The left and right twists of the center line of the drum groove, virtual grooves, etc., still cannot avoid the overlapping of yarn loops, resulting in uneven winding density of the bobbin, which seriously affects the production quality of the subsequent winding process
