The surface towards piezo-electric device 34 of linkage unit 35 is formed with the female thread portion (not shown).The bar portion (not shown) that far-end has male thread portion stretches out from the surface towards piezo-electric device 34 of another linkage unit 36.This bar portion extends through this to piezo-electric device 34 and the fixed mount between piezo-electric device 34 33, and male thread portion and internal thread part phase-splitting are twisted and closed.Therefore, under piezo-electric device 34 was fastened on state on the fixed mount 33, linkage unit 35,36 was supported by fixed mount 33.In addition, linkage unit 35,36 is via bar portion and fixed mount 33 electric connections.Guide member 31 is fixed on the far-end of one of linkage unit 35,36 separately.
Oscillator 37 is connected on the oscillator 39.Battery lead plate 38 is connected on the oscillator 39 by electric wire 40a, and the ground terminal of oscillator 39 is connected on the fixed mount 33 by electric wire 40b.Therefore, in each piezo-electric device 34, the surface potential that contacts with fixed mount 33 be in earthing potential (zero) with corresponding linkage unit 35 or 36 surface potentials that contact.Oscillator 39 excites oscillator 37, so that fixed mount 33 is on the vibration nodal point, the far-end of linkage unit 35,36 is positioned on the vibration antinode.Oscillator 39 excites oscillator 37, so that guide member 31 is to be higher than the frequency vibration of audio frequency.
Shown in Fig. 2 A and 3A, each guide member 31 comprises the oscillating plate 41 of two mutual opposed arrangements.In a preferred embodiment, guide member 31 is shaped as on the fibre bundle direct of travel that to observe be symmetrical.Oscillating plate 41 also is configured as symmetrical structure.Each oscillating plate 41 comprises bottom part 41a, mid portion 41b and leader 41c.On the direction that fibre bundle is advanced, the width of mid portion 41b is narrower than the width of bottom part 41a.Leader 41c is basically perpendicular to mid portion 41b and extends along the direction that fibre bundle is advanced.Bottom part 41a and mid portion 41b are configured to the gripper shoe part.Dividing plate 42 and bottom part 41a monolithic molding.Two oscillating plates 41 are bonded to each other via dividing plate 42 therebetween.When the oscillating plate 41 via dividing plate 42 combinations is connected to and linkage unit 35, in 36 during the far-end of a corresponding linkage unit, bolt 43 is inserted through bottom part 41a and dividing plate 42, and is screwed into the screwed hole (not shown) that is positioned at be associated linkage unit 35 or 36 far-ends.In this way, that corresponding with it linkage unit fixes in oscillating plate 41 and the linkage unit 35,36.
Fig. 2 B is the partial side view that is positioned in a pair of oscillating plate 41 of each guide member 31 towards an oscillating plate on the right side of fibre bundle direct of travel.This oscillating plate is observed from the left side.Shown in Fig. 2 B, leader 41c comprises slot part 44, and this slot part is formed with downstream guiding channel 44a (outlets direct passage) and the inlet guiding channel 44b (upstream guiding channel) that is connected with downstream guiding channel 44a.The part that slot part 44 forms downstream guiding channel 44a has constant depth (perpendicular to the size on Fig. 2 B paper direction) and constant width (size among Fig. 2 B on the vertical direction).As the guiding surface that forms downstream guiding channel 44a, leader 41c comprises flat surface 44a1 and a pair of mutual opposed aid in guide surface 44a2 that extends in parallel in the fibre bundle direct of travel.Aid in guide surface 44a2 has limited the fibre bundle that passes downstream guiding channel 44a and has moved along flat surface 44a1 on the direction vertical with the fibre bundle direct of travel.Equally, slot part 44 part that forms inlet guiding channel 44b has the degree of depth and the width that constantly increases towards upstream portion.In other words, the sectional area of inlet guiding channel 44b increases towards upstream portion.For example in a preferred embodiment, oscillating plate 41 is made by compacting aluminium based metal plate.Aluminium based metal refers to aluminum or aluminum alloy.
As the guiding surface that forms inlet guiding channel 44b, leader 41c comprises sides tapered surface 45a and the surperficial 45b of top, lower tilt that intersects with sides tapered surface 45a.The inlet guiding channel moulding section 45 of leader 41c forms definite shapes, is applied on the fibre bundle from the sidepiece corresponding with sides tapered surface 45a with top, sidepiece that lower tilt surface 45b is corresponding to allow acoustic pressure.One of contrast surface of sides tapered surface 45a and a pair of oscillating plate 41 of each guide member 31 is corresponding.Top, lower tilt surface 45b are the surfaces of intersecting with sides tapered surface 45a.In other words, the inlet guiding channel moulding section 45 of leader 41c forms definite shape, from the sidepiece corresponding with the apparent surface (sides tapered surface 45a) of oscillating plate 41 with homophase crossing surface, surface (top, lower tilt surface 45b) corresponding sidepiece is supplied to fibre bundle to allow acoustic pressure.In view of the above, " with the surperficial corresponding sidepiece that intersects with the oscillating plate apparent surface " refers to vertical direction and diagonal when fibre bundle is advanced in the horizontal direction, refer to horizontal direction and diagonal when fibre bundle is advanced in vertical direction.In a preferred embodiment, shown in Fig. 2 A and 3B, inlet guiding channel moulding section 45 is configured to have groove shape cross section.Slot part 44 has the entry depth size of part of inlet guiding channel 44b greater than the thickness D of the gripper shoe part that is configured to bottom part 41a and mid portion 41b, and the width W size of inlet guiding channel moulding section 45 is greater than the thickness D of gripper shoe part.
Each oscillating plate 41 comprises the qualifying part 46a of downstream that lays respectively at downstream guiding channel 44a and the upstream that enters the mouth guiding channel 44b, 46b.Qualifying part 46a, the 46b side-looking is a triangle, and limits the motion of fibre bundle on left and right directions.This combines with therebetween dividing plate 42 to oscillating plate 41, so that leader 41c is opposed mutually and be formed with certain interval betwixt, thereby prevents that leader 41c from disturbing each other when being encouraged vibrating device 32 vibrations.
Constitute guide member 31 two oscillating plates 41 each comprise the guiding channel that is used to guide fibre bundle.The inlet guiding channel 44b of the guiding channel side of comprising truncated cone shape and the downstream guiding channel 44a of guiding channel 44b that enter the mouth certainly with the straight extension of constant cross-section.Each oscillating plate 41 comprises the guiding surface that guides fiber bundle F, so that the width of fibre bundle narrows towards the direct of travel of fiber bundle F.Guiding surface comprises flat surface 44a1, aid in guide surface 44a2, sides tapered surface 45a and top, lower tilt surface 45b.According to the spinning situation, the gap that each guide member 31 is configured as between the opposition guiding surface (flat surface 44a1) that makes a pair of downstream guiding channel 44a is less than or equal to 1mm.
Before the fine spining machine operation, the position of adjusting bracing frame 16,17 according to spinning material is suitably to adjust the position of middle bottom roller 13 and back bottom roll 14.Position according to middle bottom roller 13 and back bottom roll 14 is adjusted the position of middle top roller 22 and back top roller 23.
When fine spining machine moved, fiber bundle F was drafted in three roller formula drawing-off parts of drawing machine 11, was imported into the retained part of a pair of final transmission roller 24 afterwards via guide member 31, and derived from final transmission roller 24.At the fine spining machine run duration, driving oscillator 39 makes oscillator 37 vibrate (for example, about 30KHz) on the resonant frequency of guide member 31.This just impels linkage unit 35,36 extensional vibrations, thereby makes guide member 31 vibrations.Therefore, acoustic pressure results from the wall portion surface of inlet guiding channel 44b and downstream guiding channel 44a.Acoustic pressure acts on fiber bundle F on the direction that fibre bundle is narrowed.
Fiber bundle F when it passes the position corresponding with enter the mouth guiding channel 44b and downstream guiding channel 44a by boundling.Pass down after the bite between clamping roller 24a and the last clamping roller 24b, fiber bundle F is moved downstream and is twisted simultaneously.Afterwards, fiber bundle F is wound on the yarn tube (not shown).Final transmission roller 24 is when rotated a little faster than the superficial velocity of preceding bottom roll 12 and front upper roller 21.After passing the bite of a pair of final transmission roller 24 with suitable tension force, fiber bundle F is moved downstream and is twisted simultaneously.
In conventional art, guide member is designed to two tabular oscillating plates, and acoustic pressure only acts on fiber bundle F from a pair of apparent surface.Therefore, fiber bundle F is in along apparent surface's direction on spread apart vertical with the fiber bundle F direct of travel.In this case, the abundant boundling of fiber bundle F.Yet, in a preferred embodiment, there is sound wave to produce at the inlet guiding channel 44b place that is positioned at fiber bundle F direct of travel upstream, thereby acoustic pressure from the corresponding sidepiece of the apparent surface of oscillating plate 41 (be sides tapered surface 45a) and with the top of intersecting (present embodiment is the right angle) with sidepiece inclined surface 45a, the corresponding side action in lower tilt surface in fiber bundle F, to narrow the width of fiber bundle F.As a result, different with routine techniques, fiber bundle F also has been limited on the direction vertical with the fiber bundle F direct of travel along the diffusion of sides tapered surface 45a when being directed.Therefore, fibre bundle is by abundant boundling, and the spun yarn quality is improved.
Compared with the spun yarn quality that the ring ingot spinning frame with conventional fibre boundling equipment is spun into by the spun yarn quality that the ring ingot spinning frame of the fiber bundle concentrating apparatus 30 with preferred embodiment is spun into, this conventional fibre boundling equipment comprises the guide member by two plate vibration plates configurations.
In cotton yarn (combed yarn: 40) spin with the ingot speed of 20000rpm, coarse count yarn (carded yarn: 10) spins with the ingot speed of 10000rpm.Length to per hundred meters existence of spun yarn of being obtained is monitored and single end strength is checked more than or equal to the total quantity of the filoplume (S3) of 3mm.The result is shown in Fig. 4 A and 4B.Because hairiness number reduces and single end strength strengthens, the spun yarn quality improves.
Shown in Fig. 4 A, compare with the spinning frame with conventional plate vibration plate (comparative example), adopt that the spinning frame (embodiment) of the guide member 31 with preferred embodiment is spun in a cotton yarn and the coarse count yarn filoplume (S3) quantity all significantly be reduced to half in addition still less.In addition,, compare, adopt the single end strength of this preferred embodiment spinning frame to increase about 30% with the single end strength that obtains by the spinning frame of comparative example for middle cotton yarn.For coarse count yarn, to compare with the single end strength that obtains by the spinning frame of comparative example, single end strength has increased by 10% or bigger.
Preferred embodiment has following advantage.
(1) fiber bundle concentrating apparatus 30 has a pair of guide member 31 and encourages the portion of shaking 32, this guide member comprises the guiding surface that guides fiber bundle F so that the width of fiber bundle F narrows towards the fiber bundle F direct of travel, and this encourages that vibrating device makes guide member 31 vibrations so that acoustic pressure acts on fiber bundle F narrowing on the width of fiber bundle F.Each guide member 31 comprises two mutual opposed oscillating plates 41.Each oscillating plate 41 comprises leader 41c, bottom part 41a and mid portion 41b, this leader is provided with guiding channel, and the cross-sectional area of the downstream part of this guiding channel is littler than the cross-sectional area of its upstream portion, and this mid portion is provided with the gripper shoe part.Oscillator 37 is connected in the near-end of gripper shoe part, and the far-end of leader 41c and gripper shoe part is one-body molded.Leader 41c is configured as and allows to apply acoustic pressure from sidepiece corresponding with the apparent surface of oscillating plate 41 (being flat surface 44a1 and sides tapered surface 45a) and the sidepiece (being aid in guide surface 44a2 and top, lower tilt surface 45b) corresponding to crossing surface, surface with homophase to the fiber bundle F of passing guiding channel and towards the direction that reduces the fiber bundle F width.Therefore, different with routine techniques, fiber bundle F also has been limited on the direction vertical with the fiber bundle F direct of travel along the apparent surface's of oscillating plate 41 diffusion when being directed.In view of the above, fibre bundle is by abundant boundling, and the spun yarn quality is improved.
(2) as the guiding surface that forms downstream guiding channel 44a, leader 41c comprises the flat surface 44a1 that extends in parallel in the fiber bundle F direct of travel.The cross section that inlet guiding channel 44b is connected in downstream guiding channel 44a increases towards upstream portion.Therefore, fiber bundle F when it passes inlet guiding channel 44b and downstream guiding channel 44a by boundling.Fiber bundle F is accepted acoustic pressure when passing downstream guiding channel 44a, this moment, fiber bundle F remained on the boundling state.Because downstream guiding channel 44a has the flat surface 44a1 that extends in parallel with the fiber bundle F direct of travel, the thickness of the fiber bundle F that is derived by leader 41c is stable.
(3) observe on the fibre bundle direct of travel, guide member 31 is configured as symmetrical structure.In view of the above, the oscillating plate 41 that only uses 37, two of single oscillators to dispose guide member 31 separately just can effectively be vibrated to required amplitude.
(4) has the width W of inlet guiding channel moulding section 45 in groove shape cross section greater than the thickness D of gripper shoe part.Therefore, the entrance cross-section that can increase the inlet guiding channel is long-pending, and is not subjected to be fit to the partly restriction of the thickness D of (that is, bottom part 41a and mid portion 41b) vibration of gripper shoe.This has been avoided fiber to stop up in the porch.
(5) each leader 41c comprises aid in guide surface 44a2, this surface-limited pass downstream guiding channel 44a fiber bundle F on the direction vertical, move along flat surface 44a1 with the fiber bundle F direct of travel.Therefore, when fiber bundle F was passed downstream guiding channel 44a, acoustic pressure can not only go up (that is, flat surface 44a1) and act on fiber bundle F from the apparent surface of oscillating plate 41, can also act on fiber bundle F from aid in guide surface 44a2.In view of the above, fibre bundle can be advanced when keeping the boundling state.
(6) except the inlet guiding channel 44b and downstream guiding channel 44a that cover whole fiber bundle F basically, each guide member 31 also comprises downstream that is positioned at downstream guiding channel 44a and the qualifying part 46a upstream and that be located at fiber bundle F direct of travel both sides that enters the mouth guiding channel 44b, 46b.Therefore, with unqualified part 46a separately, the guide member 31 of 46b is compared, fiber bundle F from preceding bottom roll 12 and front upper roller 21 derivation can import inlet guiding channel 44b glossily, and can import final transmission roller 24 from the fiber bundle F that downstream guiding channel 44a derives when keeping the boundling state.
(7) because oscillating plate 41 compression mouldings, compare with the example of the oscillating plate 41 of excision forming, reduced manufacturing cost.
Embodiment is not limited to top described, such as also carrying out following modification.
As long as area of section constantly increases towards upstream portion, the cross sectional shape of the inlet guiding channel 44b of each guide member 31 is not limited to rectangle.For example, inlet guiding channel 44b can form the hexagonal cross-section that has shown in Fig. 5 A, also can form the circular cross-section that has shown in Fig. 5 B.In other cases, when encouraging vibrating device 32 vibration guide members 31, produce sound wave so that the corresponding sidepiece in the surface that acoustic pressure intersects the surface from the sidepiece corresponding with the apparent surface of a pair of oscillating plate 41 with homophase works to the fiber bundle F of passing the guiding channel 44b that enters the mouth, with to fiber bundling.Thereby, the abundant boundling of fibre bundle, the spun yarn quality is improved.The cross sectional shape of inlet guiding channel 44b can for example can be triangle or octagonal for being different from rectangle and hexagonal arbitrary polygon shape also.In addition, as substituting of circle, the cross sectional shape of inlet guiding channel 44b can be ellipse.
As long as guide member 31 forms symmetrical structure, the inlet guiding channel 44b that is formed by a pair of leader 41c need not to be configured as the shape around whole fiber bundle F.For example, shown in Fig. 5 C, the cross section is the passage that a pair of leader 41c of L type can form upper opening.Cover plate 47 can cover opening portion has the square-section with formation inlet guiding channel 44b.For example, cover plate 47 can be fixed in (shown in Figure 1A) on the weighting arm 20, and when weighting arm 20 was in compacted position, cover plate 47 was set to cover the upper opening part of inlet guiding channel 44b.Under this configuration, cover plate 47 is non-vibrating.When encouraging a pair of oscillating plate 41 of vibrating device 32 vibration, acoustic pressure from the left side, right side and downside work to the fiber bundle F of passing inlet guiding channel 44b.Though acoustic pressure is not applied on the fiber bundle F from the top side of inlet guiding channel 44b, cover plate 47 same restriction fiber bundle F apparent surfaces along a pair of oscillating plate 41 on the direction vertical with the fiber bundle F direct of travel spread.Therefore, the fiber bundle F of passing inlet guiding channel 44b with the boundling state downstream guiding channel 44a move, and keep the boundling state to pass downstream guiding channel 44a.In view of the above, with respect to routine techniques, the spun yarn quality is improved.
Each guide member 31 need not to form the oscillating plate 41 of symmetrical structure, and it is asymmetric also can being configured to two oscillating plates.For example, shown in Fig. 5 D, guide member 31 can be set to asymmetric oscillating plate 48a, 48b.In this case, use the different vibrating devices of encouraging to vibrate two oscillating plate 48a, 48b so that this to leader 41c with suitable amplitude vibration.
Each guide member 31 comprises and is set to mutual opposed oscillating plate.As long as oscillating plate has been arranged to guiding channel, the area of section of this guiding channel is compared with upstream portion and is narrowed towards the downstream part, and acoustic pressure is from applying to the fiber bundle F of the inlet guiding channel 44b that passes guiding channel at least with the corresponding sidepiece of the apparent surface of oscillating plate with sidepiece that the apparent surface is intersected, and oscillating plate just can form arbitrary shape.For example, the downstream guiding channel 44a that is formed on each leader 41c need not to have two relative aid in guide surface 44a2, can include only flat surface 44a1.Selectively, guiding channel 44a in downstream can comprise among flat surface 44a1 and two aid in guide surface 44a2 only one.In these cases, fiber bundle F is being passed inlet guiding channel 44b up to I haven't seen you for ages with suitable manner by boundling.Therefore, compare with routine techniques, the spun yarn quality is improved.
Can omit qualifying part 46a, 46b.
The far-end of linkage unit 35,36 can not be in the antinode of extensional vibration.Yet, when the far-end of linkage unit 35,36 is in the position corresponding with the extensional vibration antinode, less to the required driving energy of required vibrational state for vibrating guide member 31.If the far-end of linkage unit 35,36 is departed from the extensional vibration anti-node location, distance be preferably biased to distance between contiguous node and the antinode 20% within.
Suppress the oscillating plate of making 41 as adopting, 48a, 48b substitutes, and oscillating plate 41,48a, 48b for example can and be suppressed the method that combines and make by cutting or cutting.
Oscillating plate 41,48a, 48b not only can also can be made by other metals by the aluminium based metal manufacturing.
As adopting bolt that guide member 31 is screwed onto substituting of linkage unit 35,36, guide member 31 also can be secured on the linkage unit 35,36 by brazing, welding or with adhesive.
As substituting of the oscillator 37 that is configured to have adopted piezoelectric unit, encourage vibrating device 32 and can have the oscillator 37 that is configured to magnetostriction unit or ultra-magnetic telescopic unit.
In order to spin the high-quality yarn that is referred to as compact yarn, fiber bundle concentrating apparatus 30 need not be arranged on the position of the upstream that is positioned at final transmission roller 24 between final transmission roller 24 and the front roller 12,21.For example, in the drawing machine of fine spining machine, fiber bundle concentrating apparatus 30 can be arranged on rear roller and be wound with on every side on the position between the middle roller of apron.In this fine spining machine, require the drawing-off ratio of spinning to be higher than conventional drawing-off ratio.Yet in conventional drawing machine, when the drawing-off ratio between rear roller and the middle roller increased, the width of fibre bundle can expand between rear roller and middle roller to be held, and fibre bundle enters middle roller with enlarged state.In view of the above, fibre bundle can't be with the suitable manner drawing-off.Yet by be provided with aforesaid fiber bundle concentrating apparatus 30 between rear roller and middle roller, fibre bundle its width before entering the middle roller that is wound with apron on every side can narrow to required width.Therefore, with routine techniques relatively, though when being driven, this drawing machine improved the drawing-off ratio at Background Region, and therefore improved whole drawing-off ratio, and drawing-off is in the same operational excellence in apron zone.
