The present invention relates to the yarn feeder of the preamble of the brake body of preamble of claim 1 and claim 11.
Background technology
WO 2006/032376A discloses the frustum of a cone brake body of a kind of wall thickness between 0.2mm and 1.0mm.Described brake body is made of the thermoplastic foil sheet material in the engineering plastics, and is the temperature control vacuum forming.Used plastic material can be polyethylene, polyvinylchloride or polyethylene terephthalate (PE, PVC, PET).
EP 1 164 103 A disclose a kind of brake body matrix and a kind of Weft feeder that is equipped with the Yarn Brake that comprises frustum of a cone brake body matrix.The brake body matrix is made by calendering engineering thermoplastic material, thermoplastic resin or heat curing plastic material, and is made of the axially short frustum of a cone brake body of peripheral frustum of a cone supporting body and the described frustum of a cone supporting body of insertion.An example of engineering plastic materials is an epoxy resin.In yarn feeder, brake body is to support the front end of fixing storage member by supporting body and by axial elasticity ground pressurized, make the brake area of inside face of frustum of a cone brake body contact circular unwinding edge.The larger diameter end of brake body is outwards protruded with respect to the storage yarn surface of storage member.The smaller diameter end of brake body matrix be positioned at storage member front end the front and be suspended on the radially star-arrangement of tension spring, the outer end of described tension spring is fixed on the support ring.Support ring is buckled in the carrier bar, and carrier bar is axially adjustable to be in the chassis bracket of yarn feeder, presses with the contact that is provided with between brake body and the storage member unwinding edge.
DE 10 2,004 051 372 A disclose a kind of brake body that is used for Yarn Brake.Described brake body is the truncated conical shell of the rule of standard, is made by the reticulated of weft yarn that comprises poly-ester fibres and warp thread.Described brake body is to be made by the high temperature deep draw.
EP 1 243 542 A disclose a kind of frustum of a cone brake body of Yarn Brake of yarn feeder.Described brake body has the brake area of the interruption that is limited by circumferential angular cutouts in a row in the truncated conical shell.Brake body is to be made or made or made by the engineering polymers of carbon fiber reinforcement by engineering heat curing polymeric material by the engineering thermo-plastic polymeric material.
EP 0534263 A1 discloses a kind of self aligning thread brake that is used for the weft yarn feed unit, and its brake body is the cone of topping, and with respect to the drum of weft yarn feed unit, is supported coaxially and pro by elastomeric element.Brake body is made of fabric or high strength synthetic fibre thin slice, is generally carbon fiber or " Kevlar (Kevlar) " fiber.Alternatively, brake body can be shaped or be shaped by the synthetic material that is coated with metal level in brake area at least by steel plate materials.
The cardinal principle frustum of a cone brake body of Yarn Brake is a worn parts, and it must often be changed, because the brake area of the unwinding edge of contact storage member can be worn and torn soon.Yarn is top unwinding between unwinding edge and brake area of storage member.At unspooling operation, yarn rotates as the clock and watch pointer, impels the radial elastic brake body and is generally relative motion enduringly between the metallo-unwinding edge.When yarn when the unwinding edge lifts brake area partly, brake body is out of shape enduringly and pauses with respect to the unwinding edge.The wearing and tearing that cause by the friction of unwinding yarn of rotation, the wearing and tearing that cause by the friction of unwinding edge and make brake area be worn by fricative heat.But the wearing and tearing of brake area can not occur equably can produce continuity point, and described continuity point is more impaired than the interval between the described point.The representative type profile of the wearing and tearing brake area of brake body is similar to pearl necklace.Such brake body must be replaced.Wearing and tearing can cause the service life of the weak point of undesirable brake body, and the brake body of relative high frequency rate is changed, because the replacing of brake body need be turned off yarn feeder and be weaved machine or braider, so the unused time that high-frequency brake body replacing can bring a lot of yarn feeders.In addition, the engineering plastic materials of known brake body forms and makes in the operation of Yarn braking, even along in each single operation process of the brake area unwinding yarn of brake body, the yarn tensioning that is caused by the brake action of Yarn Brake has shown tangible irregular.Described irregular be to cause by the cooperation between the surface of the elastomeric material of yarn and brake body, and further cause by the wearing and tearing of aggravation.Yarn is slack-free irregularly may to be the yarn damage reasons and to bring passive the interference for the insertion process weave machine or braider.These two shortcomings, i.e. fitfull yarn tensioning and the quickening of brake area worn-down are disadvantageous for the performance of brake body or yarn feeder correspondingly.
Summary of the invention
Target of the present invention is to make a kind of brake body or yarn feeder, it allows to realize consistent yarn tensioning in each of the unwinding yarn of brake area is changeed, and serve as to change frequency that brake body shut down to reduce yarn feeder the service life that makes brake body have prolongation.
This target is realized by the technical characterictic of claim 1 and claim 11.
Engineering plastics than known brake body, mainly due to the very level and smooth and tough and tensile surface of superpower recovery that resists mechanical load and heating and the brake area that cooperates with yarn and unwinding edge, so the high-performance thermoplastic polyketone material of brake body can bring the prolongation and the slack-free raising of high yarn in service life.The yarn that yarn is drawn during each process of the brake area of brake body running is stretched between the used life of whole brake body almost can both keep consistent in the extreme.The polyketone that is used for brake body is selected from following polyketone group: polyetheretherketone, polyaryletherketone, PEKK or similar polyketone.The polyketone of the same gang of high-performance thermoplastic High molecular material allows to realize the advantage of above-mentioned brake body.Be used for the emergent high-performance thermoplastic polyketone of making brake body effectively and have tensile strength between the Young's modulus and 75 to 110Mpa between about 3.0 to 4.0Gpa.
In the yarn feeder that is equipped with the frustum of a cone brake body, brake body is made by high-performance thermoplastic polyketone thin slice or paillon foil, the selection of material brings the remarkable reduction of the pass unit frequency of changing because of brake body, and brings considerably less thread wear and almost do not have the yarn insertion process of unfavorable interference.
Preferably, the polyketone of brake body has the Young's modulus of about 3.6Gpa and the tensile strength of about 90Mpa.
In a preferred embodiment, brake body comprises hemicrystalline or amorphous state high-performance thermoplastic polyketone.
Polyketone is the high performance plastics material that obtains by proton exchange from dihalide aromatic hydrocarbon and hexichol phenates.
The polyketone family that for example is used for the brake body of Yarn braking at the high-performance thermoplastic High molecular material, polyetheretherketone is to present two kinds of glass temperatures to be approximately one of polyketone family of 140 ℃ and 270 ℃, it has about 350 ℃ of fusing point, and has the height resistivity of heat degradation.And polyketone can be resisted organic and water-soluble environment, and shows very high strength-to-weight ratio, and hemicrystalline or amorphous state can get.
So far, polyketone has been used for bearing, piston, pump, compressor valve and cable insulation.Polyketone is adapted to ultrahigh vacuum and uses.Polyetheretherketone also is to be used for the improved biocompatible material that medical science is implanted, and also is used for the structure of aerospacecraft.
Because fabulous strength-to-weight ratio and to the height resistivity of heat degradation, the wall thickness of polyketone truncated conical shell only needs between 0.1mm to 0.5mm.Little wall thickness brings the very brake body of lightweight, even this brake body also can show superpower performance under the situation of the storage member of high yarn speed or relatively poor yarn qualities or minor diameter.
The superpower performance of brake body is realized by the truncated cone of homogeneity.Yet for application-specific, it is favourable using the high-performance thermoplastic polymer (as polyketone) that comprises reinforcing fiber material or even carbon fiber.
In advantageous embodiments, the slack-free conformability of yarn that the brake area of brake body and the cooperation between the yarn are brought can further be improved by providing circumference outwards to extend integrally formed flange continuously in the larger diameter end of truncated conical shell.During each process of brake area unwinding, described flange makes and larger diameter end some hardening of zone or the reinforcement of brake body weakens its fluctuation tendency, and therefore approximately brings the slack-free or even more consistent improvement of yarn at yarn.And when installing in most cases or change brake body, brake body is by manually or utilize tool in larger diameter end.Equally when utilizing high pressure gas or serviceable tool or when pointing the other parts that remove damaged yarn or cotton-wool deposit, larger diameter end is easier to be impaired, because the sharp larger diameter end of the truncated conical shell of standard is tended to scratch or broken in this generic operation.Flange is formed for the protection in larger diameter end zone of the rapid wear of brake body, and therefore helps to increase the service life.
In advantageous embodiments, flange roughly radially extends with respect to the frustum of a cone axis.Described flange is realized further defencive function, promptly under the operating conditions of difficulty, flange prevent yarn round and outwards move in the back of larger diameter end, can be at this place's flange around the salient of yarn feeder.
In another advantageous embodiments, described flange is the bevelled taper shape in contrast to truncated conical shell.That is to say that the outward flange of truncated conical shell is outwardly-bent.
In a preferred embodiment, described reverse circular cone polyketone flange has circular curvature at the axial cross section of brake body, and the section of seamlessly transitting that stretches into the larger diameter end of truncated conical shell.Between the on-stream period of brake body, described polyketone flange alleviates the vibrations tendency in the larger diameter end zone of brake body.Described flange can limit with the outside face of truncated conical shell and become about 90 ° of angles, and its bus advantageously is the straight line between smaller diameter end and the larger diameter end.
In advantageous embodiments, brake body is preferably slab by high-performance thermoplastic polyketone paillon foil or thin slice Heat forming are made.The method for optimizing of brake body moulding is temperature control vacuum forming or deep draw, preferably is under the hot conditions.
In another embodiment, the brake body of being made by the high-performance thermoplastic polyketone inserts outer frustum of a cone supporting body.Brake body qualification brake area is also formed the inside brake layer in the described supporting body of can saying so.Brake body is attachable to the inwall of described supporting body.

Brake body B shown in Figure 1 is a standard truncated conical shell 1, has smaller diameter end 3 and larger diameter end 2, frustum of a cone axis Z and straight bus.Truncated conical shell 1 has the inside face 4 and outside face 5 of continuously smooth.Inside face 4 defines the continuous brake area of circumference 6 (shown by dashed lines).Brake body comprises the high-performance thermoplastic polyketone, and described thermoplastic polyketone is selected from following polyketone group: polyetheretherketone, polyaryletherketone, PEKK (PEEK, PAEK, PEKK).Wall thickness X is between 0.1mm to 0.5mm.
Brake body B is by to thin slice or paillon foil, more preferably for the plane paillon foil or dull and stereotyped Heat forming is preferably the temperature control vacuum forming or deep draw is made.Dull and stereotyped use makes the brake body of final molding not need further processing, as cutting away the edge in smaller diameter end 3 or larger diameter end 2.But the inside face 4 of truncated conical shell 1 can have the quality or the polishing of buffed surface.High-performance thermoplastic polymer for example polyketone can be hemicrystalline or amorphous state, and even can comprise the lamination coating of enhancing.Brake body B is at least flexible in the radial direction, and along harder relatively on the axis direction of axis Z.
In embodiment illustrated in fig. 2, flange 7 (or dotted line 7 ') can be in the whole formation in larger diameter end 2 places of truncated conical shell 1.Perhaps flange 7 ' radially extend with respect to the axis Z of truncated conical shell 1, perhaps flange 7 (solid line illustrates) is the bevelled taper shape in contrast to truncated conical shell 1.As shown in the figure, when flange 7 was reverse taper shape, it can be had radius r by sphering, and can have the section of seamlessly transitting 8 of the larger diameter end 2 that stretches into truncated conical shell 1.
Yarn feeder F shown in Figure 3 (or be used to the Weft feeder of the machine of weaving, or be used for the braiding yarn feeder of braider) comprises the Yarn Brake Y that is equipped with Fig. 1 or brake body B (not shown) shown in Figure 2.
Yarn feeder F has casing 9, and described casing 9 comprises the unshowned driving engine that is used to drive axis 10.The rear portion of described axle 10 be hollow and with tilt outward extendingly to be connected around pipe 11.Storage member 13 props up rotationally and is held on the described axle 10, and by for example making the permanent magnet combined action that is arranged in storage member 13 and the casing 9, storage member 13 is prevented from and axle 10 co-rotation.Storage member 13 defines substantial cylindrical storage yarn surface 14 and is used for unshowned yarn source of supply, and described yarn source of supply is to form from the yarn winding continuously on yarn coil around pipe 11.Described yarn source of supply is to form with respect to 13 rotations of fixing storage member by making around pipe 11.The yarn source of supply unwinding of yarn from the storage yarn surface 14, be positioned at storage member 13 the top, cross circular or cylindrical-conical unwinding edge 18 and pass fixed outlet eyelet 15, described eyelet 15 props up on the support 12 that is held in casing 9 regularly.In this embodiment, yarn eyelet 15 is supported on the basket structure 17, and described basket structure 17 is buckled on the fixer 16 that is installed on the support 12.Described fixer 16 can be adjusted along support 12.
