The specific embodiment
Embodiments of the present invention are described with reference to the accompanying drawings.As shown in Figure 1, draw false twisting processing machine 100 possesses the yarn feeding unit 1A that keeps yarn feeding package 101, implements the winder unit 1C that the processed unit 1B of draw false twisting processing and yarn Y that the coiling processed is crossed form suitable package to separate the yarn Y that relaxes from the yarn feeding package 101 of this yarn feeding unit 1A.
And draw false twisting processing machine 100 possesses a plurality of processed assemblies (spindle) with above-mentioned yarn feeding unit 1A, processed unit 1B and winder unit 1C.These a plurality of spindles are set up in parallel along the direction vertical with the paper of Fig. 1.And, in order to dwindle the space being set, yarn feeding unit 1A and winder unit 1C are with overlay configuration about 2～4 spindle parts.
Be provided with the peg 201 that keeps yarn feeding package 101 among the yarn feeding unit 1A of each spindle, each peg 201 is installed on the shared bobbin cradle of a plurality of spindles 202.
The processed unit 1B of each spindle has the 1st yarn feeding roller 110, one-level heater 102, cooler 103, false-twisting device the 104, the 2nd yarn feeding roller 111 (yarn feeding device), the nozzle 105 that interweaves, secondary heater 106 and the 3rd yarn feeding roller 112 etc. that dispose successively along the flow direction of yarn Y.
The the 1st～the 3rd yarn feeding roller 110～112 is for carrying the parts of yarn Y.And, make the 2nd yarn feeding roller 111 carry yarns velocity ratio the 1st yarn feeding roller 110 send that yarn speed is fast, the 3rd yarn feeding roller 112 send yarn velocity ratio the 2nd yarn feeding roller 111 send yarn speed set slowly separately send yarn speed.Therefore, yarn Y is stretched between the 1st yarn feeding roller 110 and the 2nd yarn feeding roller 111, and on the other hand, yarn Y is by lax between the 2nd yarn feeding roller 111 and the 3rd yarn feeding roller 112.
The yarn Y that is stretched between the 1st yarn feeding roller 110 and the 2nd yarn feeding roller 111 is applied sth. made by twisting by holding type false twisting device described later (nip twister).More specifically be that yarn Y is twisted between the 1st yarn feeding roller 110 and false-twisting device 104.After stretching and being applied in the yarn Y that twists with the fingers and adding heat setting, cool off with cooler 103 (coldplate) with one-level heater 102.Twisting and by the yarn Y after the heat setting through false-twisting device 104 back untwistings.The yarn Y that has implemented draw false twisting processing like this forms the portion that interweaves on the ground, effect lower part of the air of nozzle 105 ejections that interweave, and quilt has been paid the convergence with the twisted yarn equal extent.Be interleaved nozzle 105 and paid the yarn Y of the convergence lax heat treatment of secondary heater 106 enforcements, with winder unit 1C coiling formation package.
And, be provided with in the downstream of false-twisting device 104 and be used to suppress to twist with the fingers only twisting with the fingers thread-carrier 107, being used to make yarn Y of propagates down stream to the cord roller 108 of the angle of contact of only twisting with the fingers thread-carrier 107 more than predetermined angle.About only twisting with the fingers thread-carrier 107 and cord roller 108 back are described in detail.
Describe false-twisting device 104 (holding type false twisting device) below in detail.Fig. 2 is the perspective view of false-twisting device 104.As shown in Figure 2, false-twisting device 104 has 2 groups and has a pair of belt pulley 10,11 respectively and volume hangs over this driving belt assembly 20 to the endless belt 12 on the belt pulley 10,11 (20A, 20B).
The a pair of belt pulley 10,11 of each driving belt assembly 20 has identical structure each other, the driving wheel that does not have the motor of expression be driven in rotation by driving shaft 13 but a belt pulley 10 is served as reasons among the figure, another belt pulley 11 is the driven pulley of the driven rotation of driven shaft that not have in figure by driving belt 12 to represent.
As shown in Figure 2,2 groups of driving belt assembly 20A, 20B dispose driving belt 12 separately with crossing one another.And one group of driving belt assembly 20A among these 2 groups of driving belt assembly 20A, 20B is fixed not to be had on the support of expression in the drawings, and another group driving belt assembly 20B freely is supported on the support for a spot wobble with driving shaft 13.And the driving belt 12 of the driving belt assembly 20A that the driving belt 12 of the driving belt assembly 20B of swing side is pushed to fix by air pressure is paid predetermined contact pressure through the yarn Y between two driving belts 12, and yarn Y is clamped in the cross section of two driving belts 12.So, when the driving belt 12 of 2 groups of driving belt assembly 20A, 20B is driven by drive pulley 10 respectively, apply sth. made by twisting for the yarn Y of the cross section that is clamped in driving belt 12, simultaneously with yarn Y fed downstream side (below of Fig. 2) (with reference to Japanese kokai publication hei 6-228836 communique, Japanese kokai publication sho 64-68531 communique).
But, as shown in Figure 3, when the tension force of the yarn of hypothesis false-twisting device 104 upstream sides is twisting tension T1, when the tension force of supposing the yarn in false-twisting device 104 downstreams is untwisting tension T2, generally the ratio T2/T1 with them is called the K value, and this K value is the physical property of decision yarn or the key factor of grade.The K value is big more, and untwisting tension is big more, and long filament is easy to generate broken end more, and therefore the filoplume that produces is many.Therefore, in order to suppress to produce filoplume, it is effective to reduce the K value; But when the K value reduced, false-twisting device 104 yarn fully untwisting in the downstream of twisting as shown in Figure 3 existed to produce not untwisting, the crimpiness of yarn was reduced or the problems such as residual moment of torsion rising of yarn, and the quality of yarn is reduced.Therefore, preferably do not reduce the K value, suppress the generation of filoplume.
As shown in Figure 1, the yarn of being twisted by false-twisting device 104 is at false-twisting device 104 and control yarn and apply interval between the 2nd yarn feeding roller 111 of feeding by untwisting.And as shown in Figure 3, the position (de-twist point) that yarn Y begins shredding changes with K value (T2/T1).That is, de-twist point increases with the K value and near false-twisting device 104, reduces and away from false-twisting device 104 with the K value.And, in fact between false-twisting device 104 and the 2nd yarn feeding roller 111, dispose the parts that various thread-carriers or tension pick-up etc. become the resistance on the sliver passage, owing to the reason of these resistances causes the de-twist point instability easily.And under this de-twist point unsure state, the length of long filament or untwisting tension aspect are easy to generate deviation, so filoplume increases.
Therefore the false twist processing machine 100 of present embodiment be provided with in the downstream of false-twisting device 104 as shown in Figure 4 with yarn Y advance and driven rotation, and suppress the yarn Y that sends from false-twisting device 104 the sth. made by twisting propagates down stream only twist with the fingers thread-carrier 107 (only twisting with the fingers parts).Here, false-twisting device 104 with only twist with the fingers the resistance body that does not have thread-carrier etc. to contact between the thread-carrier 107 with yarn, the yarn Y that was twisted by false-twisting device 104 is directly hung over by volume and only twists with the fingers on the thread-carrier 107.
As Fig. 5, shown in Figure 6, only twist with the fingers thread-carrier 107 and possess and be relative status and be bearing in 2 rotating discs 30 on the rotating shaft 31 by 32 on bearing.On the along the circumferential direction equally spaced position of peripheral part of a side of each rotating disc 30 (the face side relative), be and be provided with multi-disc fin 33 radially with another rotating disc 30.Each fin 33 edge part be shaped as from its top slowly to tilt to cardinal extremity, and be formed with to the outstanding lug boss 34 of another rotating disc 30 at the base end part of each fin 33.
2 rotating discs 30 link with a plurality of bolts 35 under their fin 33 opposed states.In this state, the fin 33 of 2 rotating discs 30 is interconnected along the circumferencial direction of rotating disc 30 as shown in Figure 7.And, hanging under 2 states between the rotating disc 30 at yarn Y volume, this yarn Y sees that along edge 36 sides of a plurality of fins 33 of 2 rotating discs 30 indention moves.At this moment, yarn Y contacts with multi-disc fin 33, so the propagation of its sth. made by twisting is suppressed, and becomes non-twist state through the yarn Y that only twists with the fingers behind the thread-carrier 107.
Utilization is only twisted with the fingers thread-carrier 107 and is suppressed false-twisting devices 104 and pay the sth. made by twisting of yarn Y and propagate into downstream one side like this.So, in the downstream of false-twisting device 104, the de-twist point of yarn Y is fixed on the position of only twisting with the fingers thread-carrier 107, and is more stable, suppresses the generation of filoplume.
And, for the propagation of the sth. made by twisting that more positively suppresses yarn Y, need picture make as shown in Figure 4 yarn to the angle of contact θ that only twists with the fingers thread-carrier 107 greatly to certain degree.Therefore, present embodiment be provided with in the downstream of false-twisting device 104 with yarn Y advance and the cord roller 108 of driven rotation, utilize this cord roller 108 that the sliver passage is changed in the downstream of false-twisting device 104, guarantee that yarn Y is more than the angle (for example 45 °) that the angle of contact θ that only twists with the fingers thread-carrier 107 is being scheduled to.But, by in the configuration of the various thread-carriers in false-twisting device 104 downstreams or the 2nd yarn feeding roller 111 etc., trying every possible means, can make to the angle of contact of only twisting with the fingers thread-carrier 107 under the situation more than the predetermined angle, can not want cord roller 108 yet.
And, only twist with the fingers thread-carrier 107 and be not limited to Fig. 5～structure shown in Figure 7, as long as can driven rotation and can suppress the propagation of the sth. made by twisting of yarn Y, structure in addition also can.And, only to twist with the fingers thread-carrier 107 and can use for example stainless steel, the ceramic parts of making etc., their material is without limits.
And though lift the example of clipping device as false-twisting device 104 in the above description, false-twisting device also can be following such friction twisting formula device.
Following simple declaration friction twisting formula false-twisting device 304.As shown in Figure 8, this false-twisting device 304 possesses 3 spindles 300 that have a plurality of discoid frictional disks 301 respectively.And, the configuration mode of 3 spindles 300 be make on frictional disk 301 side faces with the yarn position contacting be helical form (zigzag), make yarn Y between a plurality of frictional disks 301 of 3 spindles, 300 rotations, contact and advance in the shape of a spiral shape, apply sth. made by twisting for yarn Y with their side face.
And even giving under the situation of yarn twisting with such friction twisting formula false-twisting device 304, when the de-twist point of the yarn of being twisted by false-twisting device 304 produced deviation, the generation of filoplume also increased.Therefore, by downstream the above-mentioned generation that thread-carrier 107 can suppress filoplume of only twisting with the fingers is set at false-twisting device 304.
If the false twist processing machine 100 that illustrated more than adopting, though the interval untwisting between the 2nd yarn feeding roller 111 of false-twisting device 104 and the setting of its downstream, but only twist with the fingers thread-carrier 107 owing to being provided with, so the sth. made by twisting of yarn Y can not propagate into the downstream of only twisting with the fingers thread-carrier 107 in this interval.That is, the de-twist point of yarn Y is stabilized in the position of only twisting with the fingers thread-carrier 107, so the length of long filament or untwisting tension can not produce irregularly, has suppressed the generation of filoplume.And, owing to only twist with the fingers thread-carrier 107 along with the advancing and driven rotation of yarn Y, thus yarn Y when only twisting with the fingers thread-carrier 107 through this by combing, can not produce problems such as the intensity of yarn Y or degree of drawing reduction.
And, false-twisting device 104 with only twist with the fingers the resistance body that does not have roller etc. to contact between the thread-carrier 107 with yarn, the yarn Y that was twisted by false-twisting device 104 is hung over by direct volume and only twists with the fingers on the thread-carrier 107.Therefore, the de-twist point of yarn Y is more stable.
And, be easy to generate under the situation of filoplume in man-hour etc. thin yarn or yarn with plurality of threads being implemented false twisting adds man-hour or added in the high zone enforcement false twisting of K value, use and especially can improve its effect when of the present invention.And, owing under the situation of paying convergence from nozzle 105 (with reference to Fig. 1) injection air that interweaves to yarn, also be easy to generate filoplume, so the present invention also is applicable to this situation.
With comparative example embodiment more specifically of the present invention is described below.
