Groove drum guide yarn electric folding-proof device employing self-adapting control and method thereof

Abstract

The present invention provides a grooved drum yarn guide electronic anti-overlapping self-adaptive control technology, which is a mode to combine the software control in the grooved drum motor control drive. The anti-overlapping swing speed sawtooth wave parameters of the motor control are set through manual intervention, not based on the variety of the yarn and the speed. The invention can measure the speed of the grooved drum and the bobbin at any moment, calculate the rotational speed slip and form a closed-loop control on the rotate speed and the rotate speed acceleration that drive the motor according to the expected yarn setting dislocation amount so as to realize quantitative control on the yarn setting dislocation amount. The invention can automatically adapt to changes of different yarn varieties, yarn winding speed and the weight and the diameter of the bobbins and can markedly increase the quality of bobbin forming, which raises the intelligent level of equipment and simplifies the operation. The invention is applied to various yarn, wire and thread winding equipments which adopts grooved drum yarn guides.

Description

technical field [0001] The technology of the invention belongs to the field of industrial automation and motor control, the application belongs to the field of textile machinery, and relates to a self-adaptive electronic anti-stacking technology for grooved drum guides. It can be applied to all kinds of automatic winders, winders, yarn doubling machines and other textile machines that use grooved drums to drive yarn guides to wind yarns. Background technique [0002] It is an important part of the textile process to wind the cop yarn into a bobbin with a winder or to combine a single yarn into a multi-ply yarn with a doubling machine. Usually, the grooved drum is used to drive the bobbin and guide the yarn, although During the winding process of the bobbin, the grooved drum uses the yarn guide groove to route the yarn to stagger the position of the yarn, but it still cannot prevent the overlapping of the yarn in the whole process. When the grooved drum and the yarn drum rota...

AI Technical Summary

Problems solved by technology

[0004] The invention provides a device and method for automatically adapting the yarn guide of the grooved drum to the electronic anti-folding method, which can solve the above-mentioned problems existing in the prior art, for example, due to the different types of yarns and the change of the winding speed, it needs to be driven by an experienced craftsman. Only by repeatedly exploring, verifying and readjusting the winding can a more suitable curve that is only suitable for this condition be debugged, and as the winding proceeds, the diameter and weight of the bobbin continue to increase, resulting in an increasing inertia and friction surface. Increased unwinding tension causes the speed to drop continuously, making the set curve inappropriate, unable to meet the needs of the whole process, and problems such as cobweb yarns appear
