Description

Make the method and apparatus of a centrifugal spinning and twisting machine running

The present invention relates to a kind of as described in the preamble a kind of centrifugal spinning and the method for twisting machine running and device of this method of enforcement according to claim 15 of making according to claim 1.

As we all know and DE 195 23 835 A1 or DE 198 02 656 A1 patent specifications describe in detail like that, centrifugal spinning at first feeds the raw material drawing-off to desired yarn count by a drafting system with one, then in the centrifugal spinning jar by a high speed rotary of yarn-guide tube input that can support with moving axially.

The feeding raw material can be to be stored in ribbon in the bar tube or one such as the rove under the unwinding of a rove bobbin.

The infed material that pulls out from the guide mouth of pipe forms yarn pile and is close to the inwall of centrifugal spinning jar and is carried by this jar.

Fibrous material obtains twisting by the revolution of centrifugal spinning jar.

The yarn that is subjected to twisting formation is banked up by the yarn-guide tube that can support on the tophan box inwall with moving axially, forms a yarn package that is referred to as the yarn cake at this place.

When so-called one process spinning, the revolution of tophan box and the output speed of infed material should mutual like this coordinations, and the yarn of coiling resultant yarn cake has had the complete twist, can be wound up on the rewinding bobbin in the input tophan box at next process.

Next the cop that the rewinding process is produced is doffed, and delivers to rewinding on the bobbin winder that is connected in the production procedure of back then, and network becomes the cross winding bobbin of a large volume.

Another kind of centrifugal spinning technology, promptly so-called two step method spinning, the output speed of tophan box revolution and infed material should be selected like this, and the yarn that is wound on the tophan box inwall when the first step is spinned at first only obtains a part of twist, the effective twist such as 60%.The twist that lacks is assigned to the yarn of banking up as yarn package that the part twist is arranged, if yarn goes out from the tophan box unwinding at the second step spinning process, while direct network on an affiliated winding device becomes the cross winding bobbin of a large volume.

This shows that not only the spinning of one-step method but also two step method all constitutes earlier a yarn package from outside to inside on a tophan box inwall.The yarn package that forms does not depend on the coiling form that is adopted, and reels or incidental looping such as flyer spindle, and an inner diameter d is arranged all the time _Gi＞0mm and a cone angle gamma _RZ≤ 90 °.

Although DE is 40 02 230 A1, described the multi-form of this yarn package among DE 41 03 771 A1 or DE 195 48 669 A1, but this for a long time yarn package is not obtained the accurate understanding of package structure or is not had accurately to understand the limit of layer.

Promptly for a long time once to every yarn by test with misread the I try to achieve yarn package and spin internal diameter, nonsystematicization ground is in the same way then.

The method that this yarn package parameter is determined is not only time-consuming and need a large amount of expenses, and is inaccuracy and unreliable very.

In view of ignorant parameter error, so centrifugal spinning is normally with high safe spacing work, thereby almost can not utilize the tophan box charging of maximum possible.

From above-mentioned prior art, task of the present invention is, creates a kind of method and apparatus, can not rely under the spinning method at that time and the method for twisting thread by the method/device, significantly improves the efficient of centrifugal spinning and twisting machine.

According to the present invention, this task is to solve by a kind of method as claimed in claim 1 and by a kind of device as claimed in claim 14.

The preferred technical solution of the present invention is the theme of dependent claims 2 to 13 and dependent claims 15 to 20.

The method according to this invention has special advantage, can measure accurate yarn package parameter with plain mode, density of texture such as yarn package, I is spun the maximum cone angle of internal diameter and/or yarn package, therefore according to understanding, can maximum utilize the spinning volume of each centrifugal spinning jar of centrifugal spinning and twisting machine and the whole efficient that can improve this frame significantly to them.

In addition, owing to avoided the over dimensioning of centrifugal spinning jar, also can make the power consumption of this frame be reduced to minimum.

In optimized technical scheme, as described in the claim 2, the yarn package that forms in the centrifugal spinning jar of benchmark yarning part increases and can collect according to a R by internal diameter size and time (t) curve.

Preferably spinning time of yarn package is fixed on the abscissa in the coordinate system, and the inner radius values at that time of yarn package records on the ordinate.

A kind of preferred form of implementation according to claim 3 is, when making R (t)-curve, comes computing with a resolution ratio that roughly is equivalent to a yarn count, therefore can reach enough accurate.

Described in claim 4, be stored in the central control unit of centrifugal spinning machine by benchmark yarning part (3) the relative yarn package parameter that records for each yarn kind.

Promptly can directly seek help from the numerical value of having stored, thereby the spinning process of " normally " yarning part starts with the adjusting of the best at once in whole later fabrication processes.

Accurately understand this main procedure parameter and make a firm especially process guide become possibility, when needs, can suitably get involved in this process guide.

Described in claim 5, learn from R (t)-curve and the reciprocating power of considering the benchmark yarning part and can express a P who represents the relative inside radius of density of texture of yarn package _KZ(R)-curve.

claim

7 and 8, the minimum inside radius and the maximum cone angle that also are applicable to definite yarn package that R (t)-curve is desirable.

Press under the yarn package situation that incidental looping makes at one, for example reaching of maximum cone angle can obviously be found out as the sudden change in R (t)-curve.In the case, the minimum inside radius of yarn package must be considered certainly.

Described in claim 8, the sudden change in a corresponding R (t)-curve means the minimum that the reaches yarn package radius of banking up under the yarn package situation of reeling by flyer spindle.

Sudden change in R (t)-curve can be owing to the appearance of a yarn string or the layer cone slide down from yarn package, and these are all collected reliably by sensing device.

Promptly for example a laser case that is designed to strip lighttype such as the additional shadow that produces by the yarn string, triggers a signal, this signal process in data determination and analytical equipment and is made in R (t)-curve and can know identification as tangible the sudden change.

Correspondingly, under a yarn package situation of pressing the incidental looping method, one because one deck slide shade of the sensing device that causes of multilayer layer perhaps, demonstrates usually to reach maximum cone angle.

A kind of preferred implementing form described in claim 9 is to handle out a statistical model immediately by the measurement data of sensing device input in data determination and analytical equipment.

For example can calculate foreseeable yarn package parameter at once, i.e. " minimum inside radius " and " maximum cone angle " of yarn package.Use a plurality of benchmark yarning parts and their measurement result of evaluation or estimate many measurement results of being docile and obedient a benchmark yarning part of preface input, can fully accurately consider the dispersion that when producing yarn package, produces with plain mode.

Here by quiet model extrapolation, can easier obtain the mean value (claim 10) of the density of texture of yarn package according to ρ (R)-curve.

As described in claim 11, also suggestion in a kind of preferred design, the yarning part computer of regular yarning part and the data determination and the analytical equipment of benchmark yarning part are online.

That is to say that when changing a batch, wherein change still unprocessed so far yarn kind, these " normally " yarning parts can promptly start soon after the benchmark yarning part starts.The yarn package parameter that requires can both be adjusted afterwards, in case when promptly they exist, be transferred to the yarning part computer of " normally " yarning part and these parameters are done adjustment adaptably.

Shown in Fig. 6 e, " maximum cone angle of yarn package " γ _{KZ (max)}Can be according to γ _KZ(R)-and curve tries to achieve, and this curve this respect can be calculated from R (t)-opisometer.

Curve IV, V and VI are corresponding to the known taper profile curve of Fig. 6 c.

Flow process according to the inventive method:

When a new yarn is to spin on a centrifugal spinning machine 1, its yarn package parameter is not known or inaccuracy is known, perhaps when spinning a kind of yarn and should change machine parameter, at first will try to achieve the yarn package parameter on a so-called benchmark yarning part 3.

Promptly at first measure relevant spinning parameters, for example " minimum diameter " d by this benchmark yarning part 3 _Gi" maximum cone angle " γ _KZAnd yarn package density structure ρ (R).

For this reason, make a yarn package 21 with the new yarn on centrifugal spinning jar 8 inwalls 20 of benchmark yarning part 3, its structure preferably is subjected to the detection of an optical sensing devices 17 enduringly, and sensing device is to be connected with analytical equipment 13 with a data determination.

Here, yarn package 21 can selectively be pressed " flyer spindle coiling " or the making of " cop " winding method.

When yarn package 21 is shaped, the data creating that data determination and analytical equipment 13 are measured according to optical sensing devices 17 R shown in the 6a (the t)-curve of publishing picture.

Data determination and analytical equipment 13 are learned to derive Fig. 6 b from this R (t)-curve and the reciprocating power of considering benchmark yarning part 3 and use I, the ρ that II and III indicate _KZ(R)-and the distribution of curve, these curves reproduce the local density ρ of yarn package 21 when different yarn package radiuses respectively.

In the same manner, data determination and analytical equipment 13 also can be measured the conical profile h of the yarn package 21 shown in Fig. 6 c _KK(R) shape.Here, curve IV represents a protruding curve, and curve V is a recessed curve, and curve VI is the conical profile shape of a linearity.

If yarn package 21 be by " incidental looping " mode make and package form proceed to layer and begin slippage till, the maximum cone angle γ that then reaches _{KZ (max)}, also can be called yarn package limiting angle, clearly visible as sudden change in R (the t)-curve as shown in Fig. 6 d.

When yarn package was shaped by " flyer spindle coiling " mode, this sudden change was shown as a yarn string in R (t)-curve, i.e. sudden change indication yarn package 21 reaches minimum inside radius R _(min)

If centrifugal spinning machine has a plurality of this benchmark yarning parts 3, be equipped with the centrifugal spinning jar 8 that separate electrical motor drives, then can be in this centrifugal spinning jar severally spin by the incidental looping mode by the spun yarn package of flyer spindle winding method and other yarn packages, and measure the yarn package parameters R simultaneously in this kind mode _(min)And γ _{KZ (max)}

Use a plurality of benchmark yarning parts simultaneously and also play positive role, because according to said method also should consider the slight dispersion that when making yarn package, can occur making a statistical model.

Preferred mode is, the yarn package parameter that is obtained according to benchmark yarning part 3 is stored in the central control unit 15 of centrifugal spinning machine 1 and is used for clearly controlling relevant or other " normally " yarning part 2 of centrifugal spinning machine 1.

In addition, in the data determination and analytical equipment 13 of benchmark yarning part 3, with for example roughly prior to statistical model of data creating of the benchmark yarning part 3 of " normally " yarning part 2 startups.

Because data determination and analytical equipment 13 optimal ways are by a data transmission system 16, article one, so-called data/address bus both can be online with central control unit 15, also can be online with the yarning part computer 14 of " normally " yarning part 2, not only can measure first yarn package parameter early like this, and these parameters can be transferred at once " normally " yarning part 2 of centrifugal spinning machine 1.

Online connection makes the optimization afterwards of these program parameters become possibility at any time.

Promptly " normally " yarning part has benefited from the measurement result of measuring in the benchmark yarning part 3 and can constantly readjust in the moment very early.
