Fig. 8 is the scheme drawing of the main portion of the longitudinal feeding device before the expression.
Below, with reference to accompanying drawing embodiments of the invention are described.Fig. 1 is the oblique drawing of the main portion of expression longitudinal feeding device of the present invention, and Fig. 2 is illustrated in the lateral plan that left folding is returned the yarn hand-off state on the A, and Fig. 3 is illustrated in the lateral plan that right folding is returned the yarn hand-off state on the B.
Common longitudinal feeding device is that a plurality of length travel assembly U1, U2, U3 are set up in parallel and constitute.Fig. 1 represents a length travel assembly U1.The 1st, be provided in prejudicially the length travel center about the yarn guide member of any side, the 2nd, be positioned at upside and unrolling the length travel center towards the rotating rotary vane of anticlockwise direction, the 3rd, be positioned at downside, the rotating toward the clockwise direction rotary vane in length travel center is unrolling, the 4th, at the supplemental pilot part of an A that turns back, the 5th, the supplemental pilot part of a B that turns back, these members constitute the main portion of a length travel assembly.
The 11st, touch roll or friction roller, the 12nd, seat of reel, the 35th, be contained in the bobbin on the seat of reel 12, P is the package of reel for yarn on the bobbin 35.The 15th, by the carriage of piece 16 supporting supplemental pilot parts 4, the 17th, by the carriage of piece 16 supporting supplemental pilot parts 5.
As turn back state shown in Figure 2 of an A of expression, yarn guide member 1 is positioned at the upside of rotary vane 2,3 up and down, is positioned at the downside of rotary vane 2,3 up and down from the outwards outstanding supplemental pilot part 4 of the lateral margin of touch roll 11.Be that supplemental pilot part 4 clamping length travel track ground only are configured the length travel central side.And above-mentioned member is entirely along genuine the setting of yarn up and down of touch roll 11 oblique crosscut yarn y.On this turns back an A, the rotary vane 3 of yarn from downside joined to the rotary vane 2 of upside.C point expression is along yarn guide member 1, rotary vane 2 make yarn towards Fig. 1 right lateral the state that traverses.Yarn guide member 1 plays a part yarn is fastened on upside rotary vane 2, and yarn guide member 1 not only determines the length travel track, also the handing-over of auxiliary yarn.Because the supplemental pilot part 4 with yarn guide member 1 auxiliary yarn handing-over just makes yarn take off from the rotary vane 3 of downside, thereby the yarn degree of crook on supplemental pilot part 4 is suppressed to the Min. that can not produce obstacle to the handing-over of yarn.Like this, because yarn guide member 1 and supplemental pilot part 4 are in the inboard (length travel central side) of length travel track, thereby by comparing the back as seen with Fig. 3, the bending of yarn is not a zig-zag, is to become to turn the word shape.
As turn back state shown in Figure 3 of a B of expression, though its projecting degree difference, the structure that yarn guide member 1 is configured in rotary vane 2,3 upsides up and down is same with Fig. 2.But it is inwardly outstanding that the supplemental pilot part 5 of rotary vane 2,3 downsides is in from touch roll 11 lateral margin opposition sides.Be that supplemental pilot ox 5 clamping length travel track ground only dispose on the opposite side with the length travel central side.At this B place of turning back yarn is joined to downside rotary vane 3 from upside rotary vane 2.D point expression along yarn guide member 1, rotary vane 3 make yarn towards Fig. 1 left lateral the state that traverses.Yarn guide member 1 plays a part yarn is taken off from upside rotary vane 2, and yarn guiding 1 not only determines the length travel track, also the handing-over of auxiliary yarn.Because supplemental pilot part 5 is fastened yarn on downside rotary vane 3, thereby the yarn degree of crook on supplemental pilot part 5 is just big than supplemental pilot part 4.Like this,, thereby compare with Fig. 2 and can know and find out that the yarn bending is not only and is turned font because yarn guide member 1 and supplemental pilot part 5 clamping length travel track ground are in both sides, but zig-zag.But, reducing by a side among an A, the B yarn degree of crook on turning back a little that turns back of the yarn about making, the damage of yarn also just reduces.And, with compare with the structure of the auxiliary yarn handing-over of the yarn guide member between rotary vane and a pair of supplemental pilot part, with the yarn guide member 1 up and down that is configured in rotary vane and about a supplemental pilot part 4,5 on turning back a little carry out Fig. 2 of yarn handing-over and the degree of crook minimizing that structure shown in Figure 3 can make yarn.
Like this, have the function of auxiliary yarn handing-over in order to make yarn guide member 1, change about turn back a place the yarn degree of crook, yarn guide member 1 is disposed prejudicially with respect to the length travel center.Below, with reference to Fig. 1 this eccentric configuration is described.O1 is the center of gyration of the rotary vane 2,3 on the length travel assembly U1, i.e. length travel center, and O2 is the center of gyration of the rotary vane on the adjacent length travel assembly U2, i.e. length travel center.The line that connects this length travel center O 1, O2 as the datum line 13 arranged side by side with the length travel track, with these datum line 13 rectangular lines as length travel line of centers 14.It is R arc sections guiding face that yarn guide member 1 forms radius.The center O O of the radius R of this yarn guide member 1 is communicated with on the normal length travel line of centers 14, but in an embodiment of the present invention, at the lateral extent ε place that takes over, and the configuration of also integrally keeping right of left and right sides supplemental pilot part 4,5 that matches with this off-centre and installation bracket 15,17.
As a result, on length travel center O 1, angle [alpha] that an A and length travel line of centers 14 constitute is turned back than on length travel center O 1 in the left side, and the right side angle 3 that a B and length travel line of centers 14 constitute of turning back is little.And the distance L 1 of 1 guiding face from length travel center O 1 to yarn guide member at an A place of turning back in the left side is lacked than the distance L 2 of 1 guiding face from length travel center O 1 to guide member of a B that turns back on the right side.In addition, left side the shorter than a turn back B and 14 of length travel line of centerss of right side of 14 of an A and length travel line of centerss of turning back apart from M2 apart from M1.
Like this, though have the yarn guide member off-centre of arc sections 1a, but because that decision length travel track is arc sections 1a, thereby make the tension force increase mitigation that becomes at the both ends of length travel track, make tension force reduce the mitigation that becomes at central portion, the original performance that yarn is guided does not have any obstacle.Promptly if the yarn guide member with arc sections 1a with respect to the length travel center function that in addition configuration prejudicially just can the auxiliary yarn handing-over of affix, the yarn degree of crook minimizing that a side in turning back a little about just making is turned back a place, thereby the damage that can alleviate yarn.
As mentioned above, about turn back an A, B form different with respect to about 14 one-tenth of crank motion line of centerss, and supplemental pilot part 4 and supplemental pilot ox 5 towards also the left and right sides is different.But the yarn degree of crook minimizing by at least one side in turning back a little about making turns back a place tails off the damage of yarn.The damage of yarn is reduced, the handing-over of the yarn at a place of turning back about carrying out really, it is inhomogeneous that its result just produces the left and right sides.
In order to dwindle the poor of rotary vane 2,3 up and down and the drift between the touch roll (perhaps friction roller) 11, preferably rotary vane 2,3 up and down closely is provided with.For this yarn guide member 1 is provided in the upside of rotary vane 2,3 up and down, supplemental pilot part 4,5 is provided in the downside of rotary vane 2,3 up and down.Its result, make the front end of blade 2,3 and the distance between the touch roll (friction roller) 11 about turn back a little approximately impartial, thereby the yarn that is formed by drift is lagged in the left and right sides equalization to the mobile of length travel direction, can make the left and right sides shape of package end identical.
In addition, turn back about Fig. 2 and Fig. 3 an A, B place, around the rotating upward rotary vane 2 of anticlockwise direction with around the rotating rotary vane 3 of clockwise direction is through transporting the overlapping interval of yarn mutually in the opposite direction, yarn becomes freedom when yarn joins, naturally revert to the middle position of length travel amplitude by yarn tension, thus, prevented owing to the unstable package shape that forms of length travel amplitude collapses.Be provided with under the occasion of this overlapping interval, when the interval δ 1 of up and down rotary vane 2,3 being got into when too small, yarn y is processed excessive.Therefore, need interval δ 1 is suppressed to the thickness δ 20.75-1.25 of the extension thread segment that is rotary vane 2,3.
Below, with reference to Fig. 4-7 the more detailed structure of above-mentioned longitudinal feeding device is described.In Fig. 4 and Fig. 6, the diameter of the rotary vane 2 of upside is slightly littler than the rotary vane 3 of downside, even 2,3 tilted configuration of rotary vane up and down, the front end of rotary vane 2,3 is still roughly along the direction of vertical yarn channel y, by figure b as seen, the rotary vane of upside has 2 front end 2a, 2b that depart from 180 degree with respect to 1 one-tenth point symmetry ground of center O again; The rotary vane 3 of downside also has 2 front end 3a, 3b that depart from 180 degree with respect to 1 one-tenth point symmetry ground of center O.Carry out at a B place of turning back yarn from the front end 2a of upside handing-over to the front end 3a of downside, arrive when turning back a some A with the front end 3a of downside, the front end 2b of upside also arrives an A that turns back.As a result, in rotary vane 2,3 turned around the time in opposite direction, front end 2a, the 2b of two blades, 3a, 3b made yarn carry out once reciprocal along the length travel track of being determined by guide member 1 and supplemental pilot part 4,5.Certainly, the number of the front end of rotary vane 2,3 is not limited to 2, also may be taken as 3 front ends that 120 degree wait the branch configuration.Also can make a side rotary vane that 2 front ends are arranged, make the opposing party's rotary vane that 3 front ends be arranged, make the inversely proportional different structure of they angle of revolution speed.
Downside at rotary vane 2,3 is setting supplemental pilot part 4,5, and it is to assist the handing-over of yarn by being installed in carriage on this yarn guide member 1.Yarn guide member 1 and supplemental pilot part 4,5 are clipped in the middle rotary vane 2,3 from above-below direction.Supplemental pilot part 4 has outside guiding face 4a, and supplemental pilot part 5 has the guiding face 5a inwards towards length travel center O 1.Carriage 15 shown in Figure 1 have along yarn guide member 1 from the inconsistent guiding face 15a of length travel track, when the automatic change of bobbins of determining by the turntable revolution, take off put together the effect of guide member 46 of guide member 41 and yarn by yarn, the face that constitute to keep the yarn that takes off from rotary vane 2,3, yarn is in when this guiding face 15a goes up and does not carry out length travel, and the boundling that forms bobbin 35 ends is reeled.When yarn during, make yarn begin length travel with above-mentioned main points from guiding face 15a slippage.The structure of the supplemental pilot part 4,5 of use from about the following side bearing of rotary vane 2,3 does not just need above-mentioned installation bracket 15,17.Although do not need, but, can prevent really that yarn from coming off on interface portion by on above-mentioned installation bracket 15,17, guiding face 15,17 being set.
Below, with reference to Fig. 4 and Fig. 5, illustrate when carrying out the automatic change of bobbins of full reeled tubing and bare bobbin conversion, make yarn not put together guide member and the yarn used of length travel take off guide member.This automatic change of bobbins is by these operations, in turn carries out, and promptly earlier yarn is taken off from the definite length travel track of the arc sections 1a of yarn guide member 1, removes the front end of rotary vane 2,3 and the 12nd preface of fastening of yarn; Take off from the length travel track, the nature yarn vertical with the yarn road stagger with the left end of bobbin 35 forcibly, makes yarn or not is not suspended to the 2nd operation that joins in the groove of bare bobbin when completely the end of reeled tubing comes off; Outside the yarn length travel scope of bare bobbin, form the 3rd operation that boundling is reeled.
Above-mentioned the 1st operation is to take off guide member 41 by yarn shown in Figure 4 to carry out.This yarn takes off the upper lid of the longitudinal feeding device that guide member 41 double as are made of a plurality of length travel assemblies, can be slided in the face parallel with rotary vane 2,3 by driving oil cylinder 42.Usually, guiding face 41a and yarn y that yarn takes off guide member 41 can not interfere, but take off guide member 41 when outstanding slidably when yarn shown in long and two-short dash line, yarn y is guided face 41a and shifts the place ahead onto and come off from rotary vane 2,3, does not carry out length travel thus.As seen from Figure 5, it is tabulars that yarn takes off guide member 41, and the drift 41c that leads the four directions that the 41b of people portion is connected with yarn is being set.This drift 41c forms guiding face 41a with yarn guide member 1 face vis-a-vis.
Above-mentioned the 2nd operation is undertaken by the yarn of upstream that yarn takes off the guiding face 41a of guide member 41 device 43 of putting together that is arranged on shown in Figure 4.The yarn that Fig. 5 at length represents is put device 43 together by fixing guiding tube 44, is inserted in the barred body 45 in this guiding tube 44, from the vertically outstanding yarn guide member 47 of this barred body 45, barred body 45 is constituted with respect to the driving oil cylinder 47 of guiding tube 44 advance and retreat.On guiding tube 44, do not make yarn guide member 46 from parallel with the yarn road separate vertically upward keep out of the way posture, carry out 90 degree towards the posture of intersecting with the yarn road and commutate, and then the cam path 44a that moves towards the length travel direction of yarn of the posture of intersecting with the yarn road.
Above-mentioned the 3rd operation even yarn takes off the position that guide member 41 is in solid line, is undertaken by the guiding face 15a that makes yarn not carry out Fig. 1 of length travel.This guiding face 15a can see a part from the drift 41c of Fig. 5.
By such yarn take off guide member 41 and the roughly situation of the automatic change of bobbins that put together device 43 and guiding face 15a carry out as follows.Usually, yarn y carries out length travel along the arc sections 1a of yarn guide member 1.When reaching the time of automatic change of bobbins, before this yarn take off guide member 41 from solid line position towards long and two-short dash line, outstanding along the direction of front a1.Yarn y comes off from the front end of rotary vane immediately.Simultaneously, yarn is put the oil cylinder 47 of guide member 43 together towards arrow a2 direction elongation, and yarn guide member 46 becomes the posture of intersecting with yarn y shown in arrow a3, and moves along arrow a4 direction, hangs up yarn y, makes yarn rely on the extraneous left end of length travel.After this, go up the connection device of not representing by figure and carry out the handing-over of full reeled tubing and bare bobbin.After this forming boundling between an end of the slit of bare bobbin and length travel scope reels.Thus, yarn takes off guide member 41 and returns towards arrow a5 direction.But just being in the yarn guide member 46 that can form the boundling winding position is former state.Immediately, yarn y is not collided with the front end of rotary vane by guiding face 15a restriction, forms boundling and reels.After this, when driving oil cylinder 47 when arrow a6 direction is withdrawn, yarn y comes off from guiding face 15a end, is captive in the front end of rotary vane, makes yarn carry out length travel ground and begins to traverse.
Below, illustrate with reference to Fig. 4 and Fig. 7 to make the rotating in the opposite direction mutually driver train of rotary vane 2,3.Among Fig. 4, center shaft 23 can by free rotaring ground supporting with respect to substrate 21 by bearing 22.Axle drive shaft 27 can by free rotaring ground supporting with respect to substrate 21 by bearing 26.By belt pulley 28 these axle drive shaft 27 revolutions are driven.Belt pulley 28 sides at this axle drive shaft 27 are being provided with timing belt pulley 29, in belt pulley 28 opposite sides gear 30 are being set.And the timing belt pulley 32 that is meshed with synchronous belt 31 on hanging over timing belt pulley 29 is installed on the center shaft 23, makes center shaft 23, that is, the rotary vane 3 of downside and axle drive shaft 27 equidirectional ground are turned round.In addition, be installed on the ducted body 25 with gear 30 gears in meshs 33, make ducted body 25, that is, the rotary vane 2 that makes upside is along turning round with axle drive shaft 27 opposite senses.
In Fig. 7, the ratio of number of teeth by making timing belt pulley 29 and timing belt pulley 32 and the engagement of gear 30 and gear 33 be than identical, and rotary vane up and down 2,3 is turned round in opposite direction with same angular velocity.The 34th, synchronous belt 31 is applied the free gear that tension force is used.
