Specific embodiment.
Fiber accumulation device in this fiber accumulation device and the applicant's the application (the early stage publication No.2003-113450 of Japan) has essentially identical structure.Shown in Figure 1A, 13 downstream is being equipped with fiber accumulation device 11 as the final transmission roller on the drawing machine 12 of drawing-off portion.Each final roller that transmits is made of preceding bottom roll 14 and front upper roller 15 13.
This fiber accumulation device 11 has a plurality of rolls as fibre transportation portion to 16, suction section 17 and porous belts 18.Each roll is made of the roller 20 of pushing aside on a bottom roll 19a and 16, and bottom roll 19a is as driven roller, constitutes around the rotating shaft 19 of bottom roll 14 before being parallel to; Topping roll 20 presses bottom roll 19a and corresponding porous belts 18 between the two.Each topping roll 20 all by the weighting arm (not shown) support that has support component 21 between per two spindles, is supported the front upper roller 15 in the drawing machine 12 in the same way.Each support component 21 is to constitute like this, so that be combined into one with the corresponding support component that is used for front upper roller 15.
On the contrary, in the bottom of fiber accumulation device 11, corresponding to the assembly of the half spindle between the roller stand 22 in the drawing machine 12, just, four spindles in the present embodiment form a unit.The central point of support arm 23 between each phase adjacency pair of roller stand 22, roller stand 22 be provided at predetermined intervals fine spining machine vertically on.The near-end of each support arm is supported by the strutbeam (not shown), the setting of strutbeam be convenient to the rear fine spining machine of back bottom roll (not shown) vertically on extend.Each rotating shaft 19 is supported between corresponding roller stand 22 and the support arm 23.
Each rotating shaft 19 constitutes the predetermined length of the spindle (being four spindles in the present embodiment) that has corresponding to some.The bearing (not shown) that is fixed on each two end of 19 cooperates with end plug 25.End plug 25 is supported by support portion 22a in the junction surface 25a that is arranged on roller stand 22 and the support arm 23 and 23a.Therefore rotating shaft 19 is supported in the mode that can rotate between roller stand 22 and support arm 23.Each support portion 22a and 23a can support two end plugs 25 for constituting, and therefore, the energy support and connection are at the end plug 25 of the end of adjacent pair of rotary shafts 19.
There is gear 26 at the center of each rotating shaft 19 in the vertical, as the transfer part of revolving force, is used for transmitting revolving force from drive source.Gear 26 is integrally formed with rotating shaft 19.In the present embodiment, preceding bottom roll 14 is used as the drive source of rotating shaft 19, forms towards the gear part 14a of corresponding gear 26 (shown in Figure 1A) on the bottom roll 14 before each.In addition, in the mode same with support arm 23, idler gear 28 is supported by the support arm on the described near-end that is fixed on described strutbeam 27, thereby can rotate, and this idler gear 28 engages with gear part 14a and gear 26.In other words, the revolving force of bottom roll 14 is delivered to corresponding rotating shaft 19 by corresponding one group of gear part 14a, idler gear 28 and gear 26 before each.
The suction tube (not shown) is set on the fine spining machine base extends its longitudinal direction along fine spining machine (perpendicular to the paper direction of Figure 1A).Suction section 17 has the suction tube 29 and 30 that extends along the direction that is parallel to rotating shaft 19, and one is connected so that suction tube 29 and 30 is applied the tube connector 31 of negative pressure with suction tube.Tube connector 31 is positioned at the leading flank of gear 26, so that a part of lid as gear 26 and idler gear 28, and is connected to suction tube at described near-end by the tube connector 32 with folded form.Suction tube 29 and 30 first terminal part are connected with the connecting hole that both sides, the left side and the right at an end of tube connector 31 forms, and second terminal part engages with end plug 25.
Shown in Figure 1A and 2, suction tube 29 has guiding surface 29b, here towards the upstream side of roll to the bite between 16 the roller, on fibre bundle (pile) F travel direction, is extending some suction socket 29a.Suction tube 30 has guiding surface 30b, and here the suction socket 30a of Xing Chenging extends towards the downstream.In addition, on the fiber bundle F travel direction, suction tube 29 is positioned at the upstream side of the bite of bottom roll 19a, and suction tube 30 is positioned at its downstream.
Shown in Figure 1A, below near suction tube 30, be the end of the suction nozzle with battery unit 33 of single entry pneumatic plant, be used for aspirating the fiber bundle F that when yarn breakage, transmits from drawing machine 12.The near-end of suction nozzle with battery unit 33 is connected (not shown) on the suction tube.
Shown in Figure 1A, each porous belts 18 and suction tube 29 and 30 and corresponding bottom roll 19a match, make the part of porous belts 18 contact with 30, and another part contacts with bottom roll 19a with suction tube 29.Therefore, when porous belts 18 when guiding surface 29b and 30b slide, the rolling of porous belts 18 is consistent with the rotation of the roller 19a that time pushes aside.
Each porous belts 18 is to be made of seamless annular flat pattern fabric.In the present embodiment, the formation of each porous belts 18 is after fabric carries out melt process, cylindrical fabric to be cut to preset width.Shown in Fig. 1 D, the yarn that forms fabric is the heat fusing yarn 34 with nucleocapsid shape structure.In addition, in heat fusing yarn 34, hull shape part 34a links together in the cross section 35 places fusion of the yarn that forms fabric.In the present embodiment, in heat fusing yarn 34, nuclear part 34b and hull shape part 34a are made of polyamide respectively, and the polyamide that polyamide that fusing point is 260 ℃ and fusing point are 220 ℃ is used separately as nuclear part 34b and hull shape part 34a.In addition, in the present embodiment, nuclear part 34b is made of monofilament.
Fabric is by heat fusing yarn 34 woven the forming of diameter (thickness) 0.05-0.15mm.When yarn was thin, although the suction preferential interaction is on spinning fiber bundle F during the transmission yarn, the intensity of porous belts 18 was not enough, therefore, preferably uses the interior rove of scope described above.In addition, the aperture of fabric formation is than between 25%-40%.In the present invention, the aperture ratio is defined as (A2/A1) * 100 (%), wherein, the zone of the part of being surrounded by the center line (shown in the dotted line) of two adjacent warp thread 36a is A1, and hole (dash area) zone that is surrounded by two warp thread 36a and two weft yarn 36b is A2.
In porous belts 18, the yarn that constitutes fabric is not in all fusions of all cross sections 35 places.That is to say, have only 35 fusions of part cross section, make on the longitudinal direction of porous belts 18 (circumferencial direction) at least, the zone that the cross section 35 of melting zone 37---fusion is adjacent one another are, with non-melting zone 38---the zone that non-fusion cross section 35 is adjacent one another are, the distribution that they replace.In the present embodiment, melting zone 37 and non-melting zone 38 also are alternatively distributed on the width of porous belts 18.More specifically, shown in Fig. 1 C, article one, not carrying out heat, to melt the porous belts 18 of processing be a fully uniformly leno cellular, constitute with the form shown in Figure 1B and carry out the overheated porous belts 18 that melts processing, roundish fused regional 37 approximate distributions equably on whole porous belts 18, non-melt region 38 forms reserve areas.In addition, in Figure 1B, warp thread 36a and weft yarn 36b do not illustrate.
Each melt region 37 not only comprises fusion cross section 35, also comprise the hole that is surrounded by fusion cross section 35, and each non-melt region 38 not only comprises non-fusion cross section 35, also comprises the hole that is surrounded by non-fusion cross section 35.When cross section 35 fusions, heat fusing yarn 34 also is melted in the part of closing on of cross section 35, and therefore, the aperture in the melt region 37 is than the aperture ratio that is lower than non-melt region 38.In addition, melt region 37 is different with the outward appearance of non-melt region 38, and shown in Figure 1B, the state that melt region 37 is presented is different from non-melt region 38.
The ratio of melt region is the ratio of the total surface area of the gross area of melt region 37 and porous belts 18, just with the ratio of the summation of melt region 37 and non-melt region 38 areas, this ratio is preferably between 50%-95%, and is preferred between 70%-90%.If the ratio of melt region is less than 50%, it is not enough that the durability of porous belts 18 just becomes, if the ratio of melt region surpasses 95%, the flexibility of porous belts 18 just trend is not enough.In addition, for the size of a melt region 37, although this depends on the width of porous belts 18, if melt region 37 is circular, then its diameter preferably is no more than half of porous belts 18 width, and area preferably is no more than 100mm

Next, the manufacture method of porous belts 18 is described.Have the width same with finished product, carry out under the situation of melt process then at the initial porous belts 18 that forms, productivity ratio is moderate.Therefore, should at first prepare the leno cellular of length greater than finished width manyfold (for example tens times).Because the width of porous belts 18 is approximately 15-25mm, be hundreds of millimeters leno cellular so should prepare length.Then, as shown in Figure 3, utilize a device with melt process part 40 to carry out melt process, be formed with many hole 40b on the cylinder 40a of described melt process part 40, the external diameter of this cylinder 40a is approximately equal to the internal diameter of cylindrical fabric 39.The length of cylinder 40a is greater than leno cellular 39, and, 40b formation in hole greater than the zone of the length of leno cellular 39.The size of this hole 40b and the melt region 37 of porous belts 18 are complementary, and be in the corresponding position of the distribution of melt region 37 in.The end of cylinder 40a seals.
When leno cellular 39 engages with cylinder 40a from the outside, to the inner feeding of the cylinder 40a of melt process part 40 can melting heat fusion yarn 34 the high-temperature gas (for example, air) of hull shape part 34a.High-temperature gas in the feeding cylinder 40a blows to the outside of cylinder 40a from hole 40b.Then, in the cross section 35 of the heat fusing yarn 34 in the zone of the part of the hole of corresponding circle tubular woven fabric 39 40b, hull shape part 34a is melted, thus formation melt region 37.After high-temperature gas fed cylinder 40a with predetermined period of time, cylinder 40a was cooled.After cooling finishes, remove leno cellular 39 from cylinder 40a.Afterwards, leno cellular 39 is cut into predetermined width, thereby, obtain porous belts 18.
Can make the porous belts 18 that melt region 37 constitutes with perfect condition by size, quantity and the distribution of adjusting the hole 40b on the cylinder 40a.
To introduce the function of the fiber accumulation device 11 that constitutes in the above described manner below.
When fine spining machine moved, fiber bundle F was drafted in drawing machine 12, after this, directed into fiber accumulation device 11 from the transmission roller to 13.Roll to 16 with slightly faster than of the speed rotation of final transmission roller to 13 superficial velocity, thereby each fiber bundle F is passed corresponding roll to 16 bite with the tension force of appropriateness, after this, changes direction, operation is downstream twisted simultaneously.
In addition, the suction in the pipeline affacts on suction tube 29 and 30 by tube connector 31, then, passes last suction socket 29a that forms of guidance surface 29b and 30b and the suction of 30b and acts on the fiber bundle F via porous belts 18.Next, fiber bundle F moves to and suction socket 29a and the corresponding position of 30a with the state that is sucked with boundling.Therefore, compare with the spinning machine that fiber accumulation device 11 is not installed, quality of yarn is strengthened by the generation that stops filoplume and waste cotton.
Present embodiment has the following advantages.
(1) in each porous belts 18 that rotates with guiding surface 29b and the contacted state of 30b with the suction tube 29 that constitutes fiber accumulation device 11 and 30, the yarn that constitutes fabric is melted at the part place of cross part 35, and described fabric is by forming the plates that banded material (heat fusing yarn 34) is made.Therefore,, can stop the end of broken yarn and the fiber bundle F of spinning that is transmitted to be tangled even under the situation that forms the fabric fracture, and, can stop the fiber that is spun in the fiber bundle F that is transferred in the cross part 35 of yarn, to be clamped.Therefore, the technology of boundling and transmission fiber bundle F can stop deterioration, can stop the fiber that spins of the yarn that is sent to porous belts 18 to be clamped between cross part 35, is perhaps tied up on cross part.Thereby improve spinning and transmission technology.
(2) fusion cross part 35 melt region 37 and non-fusion cross part 35 non-melt regions 38 adjacent one another are adjacent one another are are gone up alternately arrangement at the longitudinal direction (circumferencial direction) of each porous belts 18 at least.Therefore, compare with the porous belts structure that all cross parts 35 are melted, the pliability of this porous belts 18 is held.Thereby porous belts 18 is with the state even running of contact suction tube 29 and 30 profile ( guidance surface 29b and 30b), suction tube 29 and 30 guiding sections as fiber accumulation device 11, and therefore, boundling and the technology that transmits fiber bundle F are prevented from worsening.
(3) melt region 37 and non-melt region 38 also replace on the width of porous belts 18, and therefore, pliability also is enhanced on the width of porous belts 18.
(4) ratio of the gross area of melt region 37 and porous belts 18 gross areas is between 50%-95%.Thereby, kept the pliability of porous belts 18, and, durability also strengthened.In addition, in order to ensure the pliability and the enhancing durability of porous belts 18, preferred, aforementioned proportion is between 70%-90%.
(5) yarn that forms porous belts 18 is made by polyamide.Thereby, even, under the situation of the approximate 0.1mm of the thickness of yarn, also guaranteed essential intensity in order to make thin porous belts 18.In addition, polyamide is with cotton compatible, and therefore, spinning and transmission can steadily be carried out.
(6) heat fusing yarn 34 often is used to provide the hud typed structure of the yarn that forms fabric (plates), and this fabric is as the material of making porous belts 18.Thereby the yarn that forms fabric is easy to be melted at cross part 35 places.
(7) in the fabric as the material of porous belts 18, heat fusing yarn 34 is used as warp thread 36a and weft yarn 36b.Therefore, compare with the situation of having only warp thread 36a or have only weft yarn 36b to be made by heat fusing yarn 34, this yarn is easy in cross part 35 fusions.
(8) can weave porous belts 18 with spun yarn precision with approximate 0.1mm.The suction of fiber bundle F also thereby effectively.
(9) porous belts 18 adopts the form of seamless annular.Therefore, fiber bundle F can be by smooth transport, and, can prevent from tiredly to be easy to propagate from any one seam.
(10) fabric that is used to form porous belts 18 is weaved by filament yarn and is formed.Therefore, compare with staple fibre yarn with same thickness, the intensity height, ventilating also is enhanced.
(11) make the required smelting process of porous belts 18 in order to carry out, the method for taking is, leno cellular 39 from outside with it under the state that engages of the cylinder 40a of porose 40b, 40b blows out high-temperature gas by the hole.Therefore, use the size and the corresponding to cylinder 40a of distribution of wherein hole 40b and melt region 37 to be formed.Porous belts 18 with the melt region 37 of wishing structure can be manufactured with the productivity ratio that increases easily.
Present embodiment is not limited to above-mentioned, also can be modified by following.
For the partly different endways structure of melt region 37 with the size of core, if the area ratio on the end portion is bigger, preferred, shown in Fig. 4 A, part goes up and forms large-area melt region 37 endways, forms the melt region 37 of small size at core.In this case, the suction stepless action by suction socket 29a and 30a is on fiber bundle F.
Can be identical the quantity of the melt region of on the width of porous belts 18, arranging 37, each row in distributing.In addition, having the melt region 37 of different size can mixed distribution.
The formation of melt region 37 is not limited to circle, can change into various suitable shapes, as an example, can be polygon, triangle, quadrangle, or oval.
Shown in Fig. 4 B, the melt region 37 that extends at interval can be formed on the end of two widths of porous belts 18 in a circumferential direction.In this case, the pliability of porous belts 18 has just been guaranteed in the existence of the non-melt region 38 between the melt region 37, and the end portion of porous belts 18 also is not easy wearing and tearing.
The melt process of the cross part 35 when making porous belts 18 also is not limited to high-temperature gas is blown out this method of hole 40b of cylinder 40a.For example, also can adopt a kind of method, leno cellular 39 engages with a roll from outside, pushes the roll with projection that another presses leno cellular 39, and this projection is rotated this roll with the form formation same with melt region 37 when heating.But, use the method ratio of high-temperature gas to be easier to.
Can on the leno cellular 39 that has with the same width of finished product, perhaps on porous belts 18, carry out melt process.
Substituting all yarns that form fabric all is to be formed by the heat fusing yarn, and the warp thread or the weft yarn that also can just form the fabric of porous belts 18 are made of the heat fusing yarn.
Heat fusing yarn 34 is not limited to shell part 34a and nuclear part 34b makes this a kind of yarn by polyamide.Also can use the shell part 34a and the nuclear part 34b of heat fusing yarn all to be made by polyester, perhaps the shell part 34a of heat fusing yarn is made by polyester, and nuclear part 34b is made by polyamide.
In the middle of described embodiment, four spindles by each unit correspondence that rotating shaft 19 and suction tube 29 and 30 are formed.But, each unit spindle (for example eight spindles) or two spindles between also can corresponding roller stand 22.In addition, all unit are not the spindles of essential corresponding equal number.That is to say, can be divided into two groups of spindles (for example, six spindles and two spindles) of varying number between the roller stand 22, and two types unit can be provided also.
Being not limited to suction socket 29a and 30a and being positioned at downstream and this a kind of structure of upstream side of fiber bundle F bite, also can be this structure of upstream side that 29 of suction tubes with suction socket 29a are positioned at bite.In this case, substitute suction tube 30 and also can use the rod tube identical, do not form suction socket 30a on the bar with the profile of suction tube 30.Therefore, make and the method for assembling can with the foregoing description basically identical.In addition, porous belts 18 can be around suction tube 29 and bottom roll 19a, not around suction tube 30.
The hop of fiber accumulation device 11 is not limited to install roll to 16 these a kind of structures.As shown in Figure 5, for example, the cross section of suction tube 44 is similar to egg type, and suction socket 44a form with the precalculated position on suction tube 44 is formed.Porous belts 18 is around the periphery of suction tube 44, so that jockey pulley 45 slidably.In addition, the rotation of front upper roller 15 is passed to topping roll 20 by gear 46, makes topping roll 20 be driven when pressing porous belts 18, thereby porous belts 18 is driven.
Common rotating shaft 19 with bottom roll 19a can be used to all spindles, so that pass through gear drive by the motor of the gear end that is positioned at fine spining machine, this type of drive with the preceding bottom roll 14 of drawing machine 12 is identical.
The present invention can be applied to the drawing machine of other types spinning machine, and is not limited to the drawing machine of fine spining machine.
Therefore, the present embodiment and the specific embodiment are considered to laying down a definition rather than limitation of the present invention.The invention is not restricted to given details, but can improve with being equal in (equivalence) in the scope of claims.
