A kind of SZ false twisting machine is simultaneously arranged in the false twisting machine, it is after 2 one threads are carried out the false twisting of S turn and Z turn respectively, carries out doubling and batches.Can obtain the no moment of torsion yarn that the moment of torsion of the moment of torsion of S folded yarn and Z folded yarn is cancelled out each other, can improve the easy zbility of yarn and open fibre, the running speed that can improve subsequent handling and the minimizing of yarn and stop the platform number.
This SZ false twisting machine simultaneously is that false-twisting device that applies the S turn and the false-twisting device that applies the Z turn are constituted in abutting connection with the ground configuration one by one.A known exemplary of this false-twisting device be a pair of belt member interconnected and make they advance in opposite direction, in joining of alternating share and (vice jaw surface) go up yarn applied false twisting.
But, one by one independently false-twisting device false twisting machine is maximized when ground disposes.Propose to use small-sized false-twisting device for this reason, it is that the circular elastic component that forms the 1st rubbing surface and the 2nd rubbing surface is being set on the periphery two sides of plectane regularly, relatively sets a pair of false twist component respectively with above-mentioned the 1st rubbing surface and the 2nd rubbing surface.
Below, with reference to Fig. 6 an example of this false-twisting device is described.Among the figure, false-twisting device is made of with disk the 101, the 1st false twist component the 2, the 1st false twist component 3 SZ false twisting simultaneously.
SZ false twisting simultaneously is to set the 1st friction circle ring element 103 and the 2nd friction circle ring element 104 on the periphery two sides of plectane 102 with disk 101.The 1st false twist component 2 and the 2nd false twist component 3 are made same structure, volume is hung jointless belt member 21 between drive pulley 22 and driven pulley 23.
Become the belt member 21 of the 2nd false twist component 3 and the tangential direction angulation θ of the 2nd friction circle ring element 104 with the 2nd false twist component 3 and the 2nd friction circle ring element 104 are interconnected.Because the 2nd friction circle ring element 104 is introduced along arrow 52 directions along the revolution of arrow 51 directions, belt member 21, thereby alternating share just can apply turn to yarn with regard to forming the abutted surface (vice jaw surface) that moves in opposite direction mutually.The 1st false twist component 2 also forms same configuration.
And, along the bisecting line of angle θ, shown in arrow 52, make a pair of yarn y1, y2 enter abutted surface (vice jaw surface), to yarn y1 apply the S turn, to yarn y2 apply the Z turn, behind doubling on the position that comes off with disk 101 from SZ false twisting simultaneously, formation one one thread y3, draw along the direction of arrow 54.
Above-mentioned use SZ false twisting simultaneously forms small-sized machine construction with the false-twisting device of disk 101 and the 1st false twist component 2 and the 2nd false twist component 3, also has the path of advancing that the makes yarn advantage simply especially that becomes when using this false-twisting device.But, compare, have turn to become shortcomings such as instability, turn number be restricted easily with common false-twisting device belt member 21 configurations interlaced with each other of the 1st false twist component 2 and the 2nd false twist component 3.
The present invention produces the unsettled reason of this turn, learns that SZ false twisting simultaneously makes after with disk, the especially shape of friction circle ring element being important factor finding out, its objective is that providing a kind of can make the stable SZ while false twisting disk of turn.
In order to achieve the above object, the present invention takes following technical scheme:
SZ false twisting simultaneously disk, it is that the circular elastic component that forms the 1st rubbing surface and the 2nd rubbing surface is being set on the two sides of the periphery of plectane regularly, on above-mentioned the 1st rubbing surface and the 2nd rubbing surface, apply rightabout false twisting, it is characterized in that respectively with respect to a pair of yarn:
The convex that the 1st rubbing surface of above-mentioned elastic component and the 2nd rubbing surface are formed respectively.
Described SZ false twisting simultaneously disk is characterized in that:
A pair of band member can join with above-mentioned the 1st rubbing surface and the 2nd rubbing surface respectively, and the 1st rubbing surface of above-mentioned elastic component and the amplitude of the 2nd rubbing surface are made with the amplitude of above-mentioned belt member roughly the same.
Described SZ false twisting simultaneously disk is characterized in that:
Above-mentioned elastic component is made the concavity section that can be contained on the above-mentioned plectane periphery.
Described SZ false twisting simultaneously disk, it is that the circular elastic component that forms the 1st rubbing surface and the 2nd rubbing surface is being set on the two sides of the periphery of plectane regularly, on above-mentioned the 1st rubbing surface and the 2nd rubbing surface, apply rightabout false twisting, it is characterized in that: the 1st rubbing surface of above-mentioned elastic component and the 2nd rubbing surface are formed convex respectively respectively with respect to a pair of yarn.
Though a pair of false twist component is adapted to and can joins respectively with above-mentioned the 1st rubbing surface and the 2nd rubbing surface, just can go up and apply rightabout false twisting with respect to a pair of yarn at this abutted surface (vice jaw surface), but because false twist component is than the easier deflection deformation of plectane, thereby the contact pressure on the abutted surface becomes inhomogeneous unanimity, but, form respectively under the situation of convex in the deflection of considering false twist component in advance and with the 1st rubbing surface and the 2nd rubbing surface, just can make contact pressure uniformity.
Though the representative member as above-mentioned false twist component is the belt member, but owing to this belt member is rolled up to hang over itself and the above-mentioned the 1st and the 2nd rubbing surface is joined, thereby, throw off the contact pressure transient that makes abutted surface because of the belt member easily, but the above-mentioned the 1st and the 2nd rubbing surface of convex just can be guaranteed uniform abutted surface after supplying the disengagement of belt member.
Described SZ false twisting simultaneously with in the disk, a pair of belt member can join with above-mentioned the 1st rubbing surface and the 2nd rubbing surface respectively, the 1st rubbing surface of above-mentioned elastic component and the amplitude of the 2nd rubbing surface are that to make the amplitude of above-mentioned belt member roughly the same.
Thus, the abutted surface that is formed by above-mentioned rubbing surface and belt member just forms the shape that can average out.
Described SZ false twisting simultaneously with in the disk, above-mentioned elastic component makes the concavity section that can be contained on the above-mentioned plectane periphery.
Thus, just can carry out the location of elastic component easily with respect to plectane.
Good effect of the present invention:
As mentioned above, because scheme of the present invention forms convex to the 1st and the 2nd rubbing surface, and this convex is can the deflection of the false twist component (for example, belt member) that joins with above-mentioned two rubbing surfaces be replenished, thereby the contact pressure that turn is added to the abutted surface on the yarn just become uniformity, can carry out the false twisting of stable brute force.Specifically, can make backtwisting side brute force (T2 tension force) reduce, can also increase twisting count, not backtwisting part can take place less.
Described scheme, can also prevent to cross the little twisting ability that causes of the amplitude of proportion by subtraction belt member and reduce owing to the amplitude of the 1st and the 2nd rubbing surface, or under too big situation, because the reduction of the excessive belt component's life that forms of friction.
Described scheme, can also easily be fastened on elastic component on the periphery of plectane the SZ that the accuracy of manufacture is good cheaply false twisting simultaneously disk.

Below, with reference to seeing that accompanying drawing illustrates embodiments of the present invention.
Fig. 1 is the schematic diagram of expression SZ of the present invention false twisting simultaneously with the structure of disk, and Fig. 2 is the schematic diagram of expression SZ of the present invention false twisting simultaneously with the action of disk.
Among Fig. 1, (a) be SZ false twisting simultaneously with the sectional drawing of disk 1, (b) SZ false twisting simultaneously side view with disk 1.
SZ false twisting simultaneously constitutes with the concavity section elastic component 5 that disk 1 by plectane 4, is fixed on the periphery of plectane 4 with being bumped into.
Plectane 4 is the rigid body formation with the circular metal plate class, and elastic component 5 is to form with elastomers such as synthetic rubber, natural rubbers.
The part along the periphery two sides of plectane 4 of elastic component 5 constitutes the 1st rubbing surface 11 and the 2nd rubbing surface 12.With respect to the 1st rubbing surface 11 configurations the 1st false twist component 2, with respect to the 2nd rubbing surface 12 configurations the 2nd false twist component 3, constitute false-twisting device thus.The structure of the 1st false twist component 2 and the 2nd false twist component 3 with reference to illustrated the same of Fig. 6, therefore put on identical symbol and omit its explanation.
Particularly, the section of the 1st rubbing surface 11 and the 2nd rubbing surface 12 is not the plane parallel with plectane 4, is the convex of the curved surface of R but form radius.This convex is that the center with the thickness direction of plectane 4 is symmetrical centre, becomes enantiomorphic form.For example, grind and form with emery wheel 13 with spill.In the illustrated embodiment, elastic component 5 usefulness sintering process are fixed on the plectane 4.The in addition part that raw rubber glue is pre-formed recessed section configuration is embedded on the plectane 4, the sulfuration of carrying out heating and pressurizing simultaneously, with its sintering on plectane 4.After this, the grinding with emery wheel 13 forms the 1st rubbing surface 11 and the 2nd rubbing surface 12.Again with the interior all sides 55 and the circumferential lateral surface 56 of grinder processing elastic component 5, be shaped to interior external diameter with regulation and the elastic component 5 of regulation amplitude W1.When section is concavity, also can carry out the processing of circumferential lateral surface 56 simultaneously.
Preferably making as far as possible little apart from δ between the outer peripheral face of the outer peripheral face 56 of elastic component 5 and plectane 4.This is because can process the 1st rubbing surface 11 and the 2nd rubbing surface 12 really.For this reason, δ is got into the size that each member is adjusted on 0.5-2 millimeter ground.
Fig. 1 (b) is the false-twisting device that expression is constituted with disk 1 and the 1st and the 2nd false twist component 2,3 by SZ false twisting simultaneously.Preferably make the amplitude W1 of the amplitude W2 of belt member 21 of the 1st and the 2nd false twist component 2,3 and above-mentioned elastic component 5 roughly the same.Because yarn y1, y2, y3 and SZ false twisting simultaneously with the configuration relation of disk 1 and the 1st and the 2nd false twist component 2,3 is and illustrated the same of reference Fig. 6, thereby all adds same-sign and omit detailed explanation.
Below, with reference to Fig. 2 the action of above-mentioned SZ false twisting simultaneously with disk 1 is described.The belt member 21 of the 1st false twist component 2 with the 1st rubbing surface 11 of disk 1, join alternately, forms the 1st abutted surface (vice jaw surface) 14 with respect to SZ false twisting simultaneously.Equally, the belt member 21 of the 2nd false twist component 3 joins, forms the 2nd abutted surface (vice jaw surface) 15 alternately with respect to the 2nd rubbing surface 12.Because belt member 21 tension force, frame in accordance with regulations hangs between two belt pulleys 22,23, middle not support, thereby deflection takes place.Because the 1st rubbing surface 11 and the 2nd rubbing surface 12 form the convex that radius is R as supplying this deflection, thereby the pressure divergence that contacts between the face of the 1st abutted surface 14 and the 2nd abutted surface 15 reduces.Consequently can be subjected to stable twisting by the yarn of turn with the 1st abutted surface 14 and the 2nd abutted surface 15.
Promptly, the convex of the 1st rubbing surface 11 and the 2nd rubbing surface 12 is preferably determined according to the distortion of paired false twisting mechanism.When tension force long in two belt pulleys, 22,23 spacings or belt member 21 was low, convex just becomes more to be protruded.In the distortion of false twist component hour, convex is also with regard to less protrusion.The shape of protruding is not limited to the circular arc that radius is R so long as can supply deflection just passable of false twist component, also can be parabola shaped, ellipse or dihedral.
Because the amplitude W2 of the belt member 21 of amplitude W and the 1st shown in Fig. 1 (b), that make the 1st rubbing surface 11 and the 2nd rubbing surface 12, the 2nd false twist component 2,3 is roughly the same, thereby the shape approximation of abutted surface 14,15 is in rhombus.Thereby can prevent because the twisting deficiency of the too small formation of amplitude W1 or because the life-span reduction of the belt member 21 of the excessive formation of amplitude W1.
Below, illustrate that with reference to Fig. 3 use is with the machines configurations example of SZ false twisting simultaneously with the false-twisting device of this false-twisting device 31 of disk 1 and the 1st, 2,3 combinations of the 2nd false twist component.Drawn at the 1st feeding roller FR1 from the yarns Y 1 of 1poy output and the yarn y2 that exports from 2poy.Between the 1st feeding roller FR1 and the 2nd feeding roller FR2, from the downstream, dispose heater H and false-twisting device 31 in order.The peripheral speed of all speed ratios the 1st feeding roller FR1 of the 2nd feeding roller FR2 is fast, and yarn here is extended.Yarn y1, y2 between false-twisting device 31 and the 1st feeding roller FR1 form the twisting state, turn in heater H 1 by heat fixation.Become backtwisting state, one side with yarn y1, y2 between the 2nd feeding roller FR2 and become an one thread, draw by the 2nd feeding roller FR2 on one side at false-twisting device 31.Then, make the fiber of 2 one threads be wrapped with, form 1 one thread y3 by nozzle I/L after, batched and formed DTY.Just form the yarn that does not have moment of torsion that the moment of torsion of S twine and Z twine is eliminated fully thus.
The following describes embodiment.
Use the performance of disk with false twisting machine shown in Figure 3, affirmation SZ false twisting simultaneously.Yarn with 150d/36f.Yarn speed is got into 800m/min, is that 1: 1.60 condition is extended false twisting with the velocity ratio of the 1st feeding roller FR1 and the 2nd feeding roller FR2.The material of elastic component 5 is synthetic rubber, uses amplitude W1=8mm, has the shape of diameter 178mm.The material that forms the belt member 21 of the 1st and the 2nd right false twist component 2,3 with elastic component 5 is a synthetic rubber, and using amplitude W1=8mm, thickness is 1.6mm.In addition, the stagger angle θ of the tangential direction of elastic component 5 and belt member 21 is taken as 105 °.
In example of the present invention, the 1st rubbing surface 11 of elastic component 5 and the 2nd rubbing surface adopt radius R=40mm, form convex; In comparative example, the 1st rubbing surface 11 of elastic component 5 and the 2nd rubbing surface 12 adopt plane.
Represented to make VR (peripheral speed of the gait of march of belt member 21/the 2nd feeding roller FR2) when being varied to 1.42-1.57 among Fig. 4, how the tension force (T2 tension force) of the backtwisting side of yarn has been changed the result of study of being done.Under the occasion of comparative example, when VR changes as mentioned above, T2 tension force remains high, both made that VR increases, why T2 tension force does not reduce yet.Therewith relatively, under the occasion of example of the present invention, even VR=1.42, tension force T2 just is reduced to below 70% of preceding example, when VR increased, T2 tension force reduced as quick as thought, when VR=1.57, was reduced to below 30% of preceding example.Along with the variation of VR, T2 tension force is reduced, this point means and is carrying out stable turn.Though the characteristic under the staggered former false-twisting device occasion of belt member is dotted, becomes characteristic with example same degree of the present invention.
When Fig. 5 represents to make above-mentioned VR similarly to be varied to 1.42-1.57, how number of twists (per 1 meter number of twists) is changed the result of study of being done.Under the occasion of comparative example, number of twists is between the lower 2500-2650; Even VR increases, why number of twists does not increase yet.Therewith relatively, number of twists is along with the increase of VR, increase into 3100 from 2800.
As mentioned above, the 1st rubbing surface 11 and the 2nd rubbing surface 12 of elastic component 5 form convex a little, and SZ false twisting is simultaneously changed widely with the performance of disk.
