The present invention relates to distribution coiling method of yarn on the yarn tube in a kind of moulding in a wind2, begin to carry out cross winding with very little coiling approximate number, described method is included in and finishes some each time, equal two circulation times of existing coiling approximate number, change the relative rotation ratio between mandrel and the traverse gear cam, make whereby and in the process of whole coiling yarn, do not produce turn back a little overlapping of the yarn circle that distributes along yarn tube side so that reach precisely controlling displacement.
Description
The present invention relates to a kind of method, this method can make it remarkable improvement to the production of being carried out the yarn tube of cross winding by nature, that drawing is synthetic or the synthetic yarn of non-drawing at large, can avoid or reduce the formation of (Specular) coiling of reflection shape thus.More particularly, it relates to a kind of with the development of method of yarn auto reeling to the cylindrical yarn tube, described yarn is distributed in middle body each other, basically press the continuous helical line attached on this yarn tube, and in the process of coiling yarn, during yarn moves back and forth, have some along yarn tube side well-distributed yarn circle and turn back a little.
In afterwards the explanation and claim, term " yarn " is meant any filamentary material, and term " bobbin " or " assembly " are any assemblies of instigating the Any shape that described material reels with helix line basically.In addition, know as many institutes, on the yarn tube in the coiling yarn, yarn must move by successive reciprocation on the direction of the rotation axis that is parallel to yarn tube supporting mandrel in the distribution mode of utilizing cross winding.This motion is called " traversing ".
In the past, proposed various auto reeling method and apparatus, in the process that assembly forms, yarn is reeled by constant rate of speed basically.The applicant is that publication number is everyone of 0375043 european patent application, and this patent application relates in a kind of synthetic threads wind2, is used to control method and the relevant device thereof that yarn distributes in yarn tube forming process.
With reference to the known relevant coiling technology in this field in the synthetic threads wind2, in the assembly forming process, during the coiling yarn, the defect problem of yarn distribution aspect is very serious.The wind2 that is used to produce the yarn assembly almost always causes concentrating on some point to be gone up and forms the yarn circle and pile up, produce projection and form rib, and on the circumference side of the yarn tube that is being shaped, often cause turn back a little overlapping.The back comprises on the one hand along the more such points of yarn tube side existence, in this place's yarn accumulation, may make very much the yarn circle that is deposited in this point form the yarn circle that comes off along yarn tube side slip, and this just hinders yarn and unclamps according to normal sequence.It is a kind of coiling defective that this rib exists, and is piled up by the overlapping yarns circle to produce, and yarn forms hard tape along assembly, as this area professional is known.For the sake of clarity, this rib hereinafter is called rib respectively, tape or " image effect " (mirror effects), and these terms are interchangeable.
The high speed cross winding is when forming an assembly on yarn tube supporter when the yarn of continuous supply, and yarn generally is subjected to traversing, promptly alternately moves in the opposite direction.In this winding process, if, the ratio K of two circulations (doublebeat) number OM of the revolution N of yarn tube supporter and horizontal mobile device is an integer, yarn certainly will be on those yarn circles that before have been wound on the yarn tube, make the circumferential outer surface of assembly produce irregular, form the hardened layer of overlapping yarn, it is highdensity rib, its infringement yarn is by normally unclamping continuously, perhaps infringement is through the homogeneity of the liquid communication of dyeing bobbin, cause continuous line layer dyeing inhomogeneous, make the color of yarn produce cyclical variation.In order to overcome this shortcoming, must select mark coiling ratio, so that make the yarn circle produce suitable slight displacement with respect to the yarn circle of before having reeled.In order to prevent that these problems from occurring, the publication number that the applicant quotes is that 0375043 European application has proposed a kind of a kind of stepped distribution method of yarn and relevant device thereof of applying on the assembly that is being shaped.In the method, described coiling ratio K progressively changes a non-integral assumed value, to prevent occurring described rib in the yarn winding process.In fact, described method has caused producing sizable improvement at the quality and the aspect of performance of the assembly that forms cross winding.
Yet the thread layers of sclerosis or bad yarn still can produce in the assembly of a cross winding sometimes.
In this respect, the turn back side that a little overlaps the yarn tube or thicken along crevice.This thickening means, on these aspects, reel for yarn around consolidation more, under the situation of the limit, make coiling may produce the slippage of yarn circle or peel off along yarn tube side, form by " the yarn circle that comes off ".
From above-mentioned observation to the methodical shortcoming of elder generation, the discovery that the contriver of present patent application is surprising method of the present invention has been avoided above-mentioned coiling defective.For this reason, this method can make the numerical value of coiling parameter set according to a kind of like this mode at any time, be the sloping portion work of wind2 along curve, each part is made up of the point with constant coiling ratio K, K is not an integer or is not (exact) mark of a strictness that the described method that proposes according to the present invention comprises following continuous handling step:
-beginning cross winding with a very little coiling approximate number OM, OM is an integer, preferably is equal to or greater than 13, so that help making that the overlapping of yarn circle occurs over just after enough big two loop number.
-finish some each time, equal two circulation times of existing coiling approximate number OM, the relative rotation ratio of change between mandrel and traverse gear cam, this OM strictness is counted corresponding to the turning back of whole circumference side of the yarn tube in being shaped, be a little overlapping of turning back that in the process of whole coiling yarn, does not produce yarn circle that tube along the line side distributes in order to reach precisely controlling displacement, to make;
-will obtain s-f by the mandrel rotation speed sensor at any time to multiply by an integer that equals existing coiling approximate number, and the value of the integer OM of the denominator of the ratio K that therefore equals to reel;
-will multiply by an integer of the molecule N numerical value of the ratio K that equals to reel at any time by the frequency that traverse gear cam rotation speed sensor obtains signal;
-more described two product values interrelate them aspect phase place, even they are synchronous, so that reduce the influence of the interference that may exist, thereby eliminate phase deviation in yarn winding process in sequence.
The feature of the method that the coiling yarn distributes also is in above-mentioned reciprocating travel of advancing, sequential volume around continuous yarn circle press helix line and reel, it is distributed in the interior middle body of screw type spiral basically.
Characteristics according to the proposed method and advantage, by the reference accompanying drawing, will be more obvious by hereinafter being described, wherein:
