A single-spindle and single-control control system and control method applied to an air-covered yarn machine

Abstract

The invention discloses a single-spindle single control system applied to an air covered yarn machine. The system comprises an upper computer, a distributed controller and an execution system. The invention further discloses a control method of the single-spindle single control system applied to the air covered yarn machine. The method includes the following steps that (1) the upper computer sets process parameters and sends the process parameters to the distributed controller; (2) whether data exist is judged; (3) the rotation speed of each motor is calculated; (4) a roller is clamped on a clamping arm; (5) an operation switch is started; (6) whether the motors operate normally or whether yarn breaks is monitored; (7) a yarn monitoring switch is started; (8) whether shuttle hooks are at zero positions is judged; (9) whether a yarn monitoring sensor works normally is monitored; (10) the thickness of the yarn is calculated; (11) the stroke of the shuttle hooks and the speed of a direct-current servo motor are calculated; (12) whether the number of pulses reaches a preset value is judged; (13) the roller is replaced when the yarn is fully reeled, and the step 1 to the step 12 are repeated. The system and the method have the advantages of being high in precision, high in production efficiency and the like.

Description

technical field [0001] The invention relates to an air-covered yarn machine technology in the textile industry, in particular to a single-spindle single-control control system and a control method applied to an air-covered yarn machine. Background technique [0002] The air-covered yarn machine is a kind of yarn processing machine. It passes the spandex delivered from the spandex feeding device with a certain draft ratio and the untwisted filament (nylon / polyester DTY) through the air covering device in compressed air. Under the action of network wrapping, two or more fibers with different physical properties are intertwined to form a yarn—air-covered yarn. Most of the existing domestic air-covered yarn machines are formed by adding a set of simple spandex conveying device and network nozzle device to the ordinary winding machine. The cost is low, and it is troublesome to change the product variety and change the process. Low-efficiency production of some low-grade or coars...

AI Technical Summary

Problems solved by technology

[0003] 1. The control systems of the current air-covered yarn machines are all centralized control types. One machine with multiple spindles can only produce one variety with one process, which cannot meet the flexibility of small batches, multiple varieties and high-tech content of manufacturers. production requirements

[0004] 2. The production efficiency is low, the control precision is not high, and the production of fine denier yarns will have defects such as many yarn breakages, many leakages, and uneven drafting multiples.
