Abstract
The aim of the invention is to simplify, in particular, the calculation of the production when making fancy yarn in ring-spinning frames with changes in mass and/or twist. To this end, the invention provides that control signal serve to alter the drafting and/or the ratio of the supply of yarn to the twisting of yarn by means of a computer (1) into which an algorithm is input by means of which the computer outputs control signals to downstream control devices (5, 15). The predetermined fineness is maintained by these control signals with regard to the change in mass due to the fact that the fineness in the area of the thin locations between the thick locations is reduced according to the produced thick locations. To this end, the control devices (5, 15) are designed for varying the rotational speed of the drives (8, 12) of the drafting assembly rolls (9, 13) and of the drive (17) of the spindles (19). In addition, the algorithm of the computer (1) is configured in such a manner that it allows the twist in the yarn to change according to the fineness in the yarn sections with varying mass so that the alpha value of the yarn remains the same.
Description
Technical field
The present invention relates to a kind of be used to the produce method and apparatus of the fancy yarn that has the fineness of yarn that changes and/or adjustable the yarn twist that changes and the device that is used on ring spinner, realizing this method adjustablely.
Background technology
The known ring spinner of for example describing in DE 40 41 301 A1 that is used to produce fancy yarn is from the article adjusting about the fineness of yarn and the twist, and the effect that is provided with meaning is regulated on this basis.The calculating of Sheng Chaning is very difficult in these cases, because will consider a large amount of relevant parameters.
Summary of the invention
Therefore task of the present invention is to propose a kind of scheme that is used for calculating simply production, if produce the words of fancy yarn of the yarn twist of the fineness of yarn that has variation and/or variation.The present invention solves above-mentioned task in the feature by explanation in claim 1 to 3 aspect the method.The device that is used to implement these methods is the theme of claim 4 to 7.
Have mass effect, promptly have the yarn of slubbing if should produce, can import the parameter of these slubbings so to computer, for example its thickness, its length and its relative distance by claim 1 or 4.The total fineness that causes for the drawing-off that makes these slubbings not improve the yarn that produces by feeding and adjusting, computer is just determined less fineness for the yarn portion section between the slubbing for details, so yarn comprises slubbing and is equivalent to initial yarn again at interior total fineness.Promptly in the zone of details, improve drawing-off, and production remains on the numerical value of original adjusting.
Computer is designed so that the controlling unit of its also such control by its loading, makes that the twist in the yarn can change by adjustable ground.The change of the twist can be carried out individually.It can be realized by the rotating speed that changes spindle.But because the big quality of motion spindle is carried out very lentamente, so preferably set, the change of the twist realizes by the supply that changes drafter because of this change.
The change of yarn qualities is in most cases made up mutually with the variation of the twist of this yarn that carries out simultaneously.Twist change in this relative set can be imported computer.But preferably set, to the computer input, with mass change relatively calculational twist change, and continue to provide as control signal, make that the twist multiplier of yarn is that so-called α value maintenance is constant.
The mass effect that does not change the twist simultaneously can keep very shortly.When the twist changes, must be noted that, attempt they balances on the yarn portion section between outlet roller pair and the spindle, and preferably transfer to thin yarn portion section.Therefore the independent twist changes and has quality that the twist simultaneously changes and changes preferred staged ground and carry out.
The ring spinner of implementing these methods has a device that is used for changing automatically drawing-off.Set, on the one hand outlet roller and input roller and intermediate calender rolls have driving mechanism separately on the other hand for this reason.Set, input roller and intermediate calender rolls or outlet roller also have for this reason rotating speed variable, the driving mechanism of the CD-ROM drive motor form of FREQUENCY CONTROL particularly, they can load the feed of adjustable frequency via control device.
In order automatically to change the yarn twist of per unit length, ring spinner is equipped with the variable driving mechanism of rotating speed of drafter.If input roller and intermediate calender rolls and outlet roller have had the variable driving mechanism of rotating speed in order to change drawing-off, in computer, there is a device so, this device allows drawing-off to change simultaneously.At this motor of FREQUENCY CONTROL is set preferably also.Scheme as an alternative, the change of the yarn twist of per unit length also can realize by the rotating speed that changes spindle.Their CD-ROM drive motor can apply the feed of adjustable frequency via control device for this reason.
The computer that loads to control device comprises the algorithm that is used on average to the parameter of the initial yarn fineness that is used for per unit length, effect intensity, effect length and the number of effects of its input.Its supply rotating speed of spindle in other words that can change drafter according to mass change in case of necessity in addition.
For the random distribution that realizes that the mass change and/or the twist change, preferably set, give random generator of the online outfit of computer.Give the only boundary value of predetermined quality variation of computer in this case, random generator produces random value within this boundary value then.

Observe article C in the example of logining, it has specified Nm11.9 and immovable specified twist 480T/m.The variation program has two steps, in the length range in first step between 40mm (length 1) and 451mm (length 2) fineness should be 100% and the twist should be 100%: just do not change fineness in the details in step 1.Length range planted agent at 40mm and 50mm in step 2 brings up to 180% with fineness, just produce a slubbing, and the twist should remain unchanged.
Random generator 3 in the computer 1 is selected length at random and is given computer with it for the step 1 in the length range between described 40mm and 451mm and for second step in the length range between described 40mm and 50mm.Quality raisings that computer is set from described length with step 2 calculated fineness in details to Nm13.4, and arrives Nm7.4 in slubbing.From these numerical value, computer 1 applies corresponding signal in step 1 control device 5.These signals control to adjust link 7 like this, make this governing loop reduce the rotating speed of the motor 8 of input roller and intermediate calender rolls 9, to such an extent as to the details fineness is brought up to Nm13.4 from Nm11.9.
After through the details length of setting, computer 1 loads for control device 5 like this, make this control device improve the quality that is used to set and improve the input roller of length and the rotating speed of intermediate calender rolls 9 via governing loop 7, to such an extent as to the drawing-off in the reduction drafter, thereby to draw fineness Nm7.44 and to produce slubbing.
Step 1 and 2 replaces continuously repeatedly, produces another length at this random generator at every turn.Computer 1 also can calculate every meter generation effect quantity and be presented at first trip.

Not only fineness but also the twist are changed for the yarn of rated value Nm14.5 and 420T/m by article A in this embodiment.Because the twist that changes is distributed on the length of yarn between drafter outlet and the spindle, thus can carry out the change of the twist, thus and also can only change yarn qualities with little ladder form.
In step 1, the length of details determines that between 120mm and 450mm random generator is selected the details length in this scope.In step 2, in the scope between 100mm and 120mm fineness is brought up to 140%, and the twist is reduced to 84%-respectively from the specified Nm and the specified twist.In step 3, in identical length range, fineness is brought up to 170%, and the twist is reduced to 76%.Step 4 is described in the real slubbing in 220mm and the 380mm length range, fineness bring up to 190% and the twist be reduced to 72%.In step 5 and 6, the rising that quality improves is symmetrical in the details of step 1 and back carries out.Repeat the order of each step.
By the first trip of form as seen at the details place, promptly in the fineness of yarn and the yarn twist at the thinnest portion of yarn section place.The actual numerical value that is provided with of the fineness and the twist averages by computer, makes it remain on specified Nm14.5 for the calculating of producing.
In the chart of Fig. 3, schematically illustrated a kind of such yarn.Dotted line 23 in the superincumbent fineness characteristic curve is represented the initial fineness and the final fineness of the yarn of the Nm14.5 that produced again.It is so little that thereby the quality of slubbing improves 24 ' also twists reductions by 25, and making the twist reduce can carry out with the form of step by following twist characteristic curve.Be high like this at slubbing 24 " locate the twist reduce by 25 " on the contrary, make that it must be with the form of a plurality of steps-in this form with three steps-carry out.
Set out thus in an example shown,, promptly improve calculational twist according to the quality of calculating and reduce to computer 1 input via a corresponding enter key, it is identical that the α value of the feasible yarn that produces keeps.Because average specified fineness of yarn 23 is held and the average twist also keeps identical, so can easily determine to produce.Therefore the yarn of the hypothesis of table 2 is made up of following segmentation:
Step 1:Nm21.7/504 T/m → α 108
Step 2:Nm15.5/425 T/m → α 108
Step 3:Nm12.7/385 T/m → α 108
Step 4:Nm11.4/364 T/m → α 108
Step 5:Nm12.7/385 T/m → α 108
Step 6:Nm15.5/425 T/m → α 108
Produce the normal yarn that does not have effect on the ring spinner if be set in, so described step can corresponding adjusting in computer.But also can shut down computer, be equipped with input mechanism for this situation control device 5 and 15, can its drawing-off of manual adjustments and twisting by means of input mechanism.
