Abstract

The invention discloses a multi-stage precise winding method for a spinning cake. The method comprises the following steps of: dividing the spinning cake into a plurality of layers of certain thicknesses along the diameter direction; forming a combination of a plurality of precise winding layers for the spinning cake by adopting precise winding control of an equal winding ratio or an equal winding angle in each layer; and providing a method for controlling parameters of a high-speed winding head to keep the change of the reciprocating speed in a reasonable and effective range in the winding process of entire spinning cake.

Description

The multistage accurate method for winding of spinning cake
Technical field
The present invention relates to a kind of method for winding of spinning cake, relate in particular to a kind of multistage accurate method for winding of automatic classification of spinning cake.
Background technology
High speed winding head has folded silk, package density and shop silk method to the factor of spinning cake outward appearance and withdrawal speed influence in spinning cake coiling and molding process.At present, the control method that on high speed winding head, adopts has control of segmentation coiling and precise winding control.
The segmentation control of reeling is to be condition with the spinning cake diameter; Divide into corresponding surely winding angle at different diameters, with the purpose of realization control spinning cake moulding, but diameter and winding angle parameter are to set with spinning technique person's experience; So it is bigger that this control method is influenced by empirical parameter; Therefore the spinning cake presentation quality is not fine, can't avoid folded silk fully, can not satisfy the demand of high-speed unwinding.
Precise winding control is divided into that waiting reels compare and etc. two types of winding angles; Waiting coiling than under the mode; The velocity variations of reciprocating apparatus is to change with winding rotary speed according to fixing ratio; Waiting under the winding angle mode, the intersection angle (winding angle) that strand forms during the reciprocating apparatus coiling and molding remains unchanged.In winding process, along with the increase of roll diameter, winding rotary speed reduces thereupon; Reciprocating speed also reduces thereupon, and for the winding mechanism of reciprocal control setup of strand and package wind2 close, above precise winding mode can meet the demands; But in the high speed winding head winding process, because reciprocating apparatus is on pressure roller, strand will pass through pressure roller could get into the chuck coiling; Therefore the variation of crank motion speed can influence the width of spinning cake; The faster spinning cake width of reciprocating speed is narrow more, otherwise the slower spinning cake width of reciprocating speed is wide more, on high speed winding head, adopts omnidistance constant grade of reeling to reel than control like this; Then spinning cake can be more and more wideer, is unfavorable for the moulding of spinning cake.
Summary of the invention
The objective of the invention is to solve the problem that after the control method that adopts on the high speed winding head can not satisfy the spinning cake moulding simultaneously, requires at present with good surface appearance, high package density and high-speed unwinding; The multistage accurate method for winding of the automatic classification of a kind of spinning cake is provided, can actv. realizes good package moulding, the high package density of spinning cake and reach the purpose of high-speed unwinding.
The objective of the invention is to realize through following technical scheme:
A kind of multistage accurate method for winding of spinning cake; Spinning cake is divided into by diametric(al) certain thickness several layers is arranged; In each layer, adopt to wait reel than or wait the precise winding of winding angle to control; Make spinning cake form the combination of some precise winding layers, the controlled variable of high speed winding head draws and comprises the steps:
(1), the winding angle through setting, calculate initial volume around than;
WR＝DH/(D tg×tan(α)×∏)；
(2), will reel than classification, calculate corresponding classification diameter;
WR n＝WR n-1-F wr×G wr；
(3), draw after the classification control in real time with the ratio of reeling;
WR n+1＝WR n×(1-F wr/F wr_s)；
(4), draw spinning cake vary in diameter increment after the classification;
WD n＝DH/(WR n×tan(α)×∏)；
(5), classification conversion diameter, when spinning cake diameter during, carry out the classification conversion greater than this computing value;
D _akt＝(WD n-WD 0)+D tg；
(6), draw the real-time diameter of spinning cake and be used to control high speed winding head, by following formula
D t＝[D tg 2+(4×V×Tex)/(DH×∏×Den)]；
Above-mentioned various in: the DH-traverse of traversing; The WR-initial coiling ratio of reeling; WR n-Di n level is reeled and is compared; WR N-1-Di n-1 level is reeled and is compared; WR N+1-Di n+1 level is reeled and is compared; α-winding angle; D TgThe diameter of-bobbin; WD 0-initial volume around than under change a grade vary in diameter increment size; WD n-Di n level reel than under change a grade vary in diameter increment size; D _ akt-spinning cake diameter when changing grade; F Wr-gradation factor, scope 0.1%～50%; F Wr_s-gradation factor corrected parameter, scope 100～1000; G Wr-coiling specific ray constant is worked as WR n＞1 o'clock, G WrBe WR nInteger part, work as WR n＜1 o'clock, G Wr=WR nD tSpinning cake diameter in the-winding process; The Tex-linear density; The Den-package density.
The beneficial effect of the invention is: relating to parameters such as hierarchical level and gradation factor, spinning fiber number, spinning cake diameter; Principle is the increase along with the spinning cake diameter; Thickness at different levels also increase gradually; The same with the increase of diameter is nonlinearities change also, and the purpose of doing like this is the quick response that guarantees bottom silk coiling and molding, and the reasonable control of reciprocating speed; For possessing continuity with existing spinning technique control; So the existing processing parameter setting value of basis of confirming of the ratio of reeling is calculated automatically; And when coilings at different levels change; Can control the added value of reciprocating speed through the adjustment of coiling ratio, can be implemented in like this in the spinning cake forming process the diminishing control of spinning cake width, wherein minification is adjusted through the gradation factor corrected parameter; Diameter is switched in classification and the real-time diameter of spinning cake all draws through calculated with mathematical model; All to carry out quick adjusting during each the conversion to each parameter and the control unit of coiling and molding; To realize bumpless transfer; Avoid the phenomenons such as folded silk, twine in the switching process, contrast prior art, this method can actv. realize good package moulding, the high package density of spinning cake and reach the purpose of high-speed unwinding.
The specific embodiment
The multistage accurate method for winding of spinning cake of the present invention; Spinning cake is divided into by diametric(al) certain thickness several layers is arranged; In each layer, adopt to wait reel and control than the precise winding of (or etc. winding angle); Spinning cake then is the combination of some precise winding layers, in the winding process of whole spinning cake the variation of reciprocating speed to remain on one rationally, in the efficient range.The multistage accurate winding number of having derived is learned model, according to spinning technology parameter and relevant classification, moulding controlled variable, generates the control of winding process classification precise winding automatically.
For example: DH=95mm; α=4.6 °; D Tg=126mm; F Wr=1.0%; F Wr-s=300;
Tex＝80Dtex；Den＝0.93。
According to formula: WR=DH/ (D Tg* tan (α) * ∏); Calculate initial volume around than WR=2.982.
According to formula: WR n=WR N-1-F Wr* G WrWR N+1=WR n* (1-F Wr/ F Wr_s); After calculating classification, the coiling ratio that corresponding spinning cake diameter is adopted.
According to formula: D t=[D Tg 2+ (4 * V * Tex)/(DH * ∏ * Den)]; The spinning cake diameter is calculated in real time.
According to formula: WD n=DH/ (WR n* t an (α) * ∏); D _ akt=(WD n-WD 0)+D TgCalculate classification conversion diameter, and, when the spinning cake diameter is changed diameter greater than classification, carry out the classification conversion through comparing with the above spinning cake diameter that calculates.
And counting statistics obtains following table:
