Description
Technical field
The present invention relates to a kind of funnel unit that is used for spinning apparatus as described in the preamble by claim 1, its have one rotatably cantilever support can drive the funnel that maybe can brake.For example by the known a kind of such funnel unit of DE 34 00 327 A1.
Background technology
The notion of so-called spinning also can be understood as twist yarn in the present invention, wherein also by a winding reel output yarn replace reel for yarn around, and yarn both can also can be made of twine short yarn.
The funnel unit of having known in the diversified embodiment of prior art has a funnel that is used for spinning apparatus, this funnel is designed for the reel for yarn that covers a spindle with one heart and also can reaches by Motor Drive by directing thread around the position, and it is suitable that wherein different funnel geometries depends on that employed method and material have turned out to be.Therefore the notion of so-called funnel not only is meant a kind of funnel shaped in the scope of the invention, and refers to a kind of bell, cylindrical, truncated cone shape and various other is fit to be used for implementing the shape of funnel spinning method, cap spinning spindle method, coil spinning method or a kind of similar spinning method, twisting method or compound winding or also refer to so-called spinning or twist yarn flier or air ring cover arbitrarily.That funnel generally is draped and cover most of vertical driven spindles from above.
The supporting of funnel and drive unit are owing to the high funnel rotating speed (making every effort to make the funnel rotating speed above 40000 rev/mins) of modern spinning method is faced with a kind of special challenge.Usually funnel has a kind of shape of elongation, so that can cover the wiring position of funnel fully.
Because yarn lead on the interior or outer surface of funnel and owing to the danger of the asymmetric accumulation of fiber is arranged within funnel, therefore the vibrationless supporting of the atwirl funnel that elongates turns out to be problematic especially, especially because frictional resistance and loss and excessive noise on bearing all must be restricted to minimum of a value, so that make the overall energy requirement of method and the manufacturing cost and the maintenance cost of device all keep less as far as possible.Wave in any case all must stop, because the contact between rotation and stationary parts may produce very big damage owing to undue oscillation makes rotary part.
A kind of possible bearing of seeking low vibration and lower resistance supporting and drive unit are to directly supporting funnel with the bearing type that surrounds funnel.Drive unit also surrounds funnel in the case mostly.A kind of advantage of such device is: because lever arm is short, and the danger of the solid uneven vibration that causes is less relatively at the funnel place.But because support arrangement is around funnel, funnel generally has a relatively large diameter and is used to cover spindle, and the bearing of therefore selecting to be fit to is proved to be unusual difficulty.The supporting structure that surrounds funnel needs relatively large position in the horizontal direction.Therefore limited the quantity of the maximum funnel that can on a funnel supporting disk, locate abreast mutually.Yarn does not lead on the outer surface of funnel.Also impossible in addition, the shading member of mobile minor diameter on funnel for example is used for covering spindle and a kind of sleeve that covers of the yarn of being reeled.
Surround the common rolling bearing of funnel outer surface, for example as disclosed in CH 681 630 A5 and EP 0 458 154 A1, has inevitably big bearing diameter, this bearing is at first because poor, the frictional resistance of speed stability is too big, noise is too big and the horizontal level demand is too big, thereby is not suitable for the high funnel rotating speed pursued.Especially as known by DE 30 47275 C2, though surrounding the use of the air bearing that the cylindrical upper section of funnel divides has reduced and drives energy and can make funnel realize driving with the high rotating speed greater than 40000 rev/mins of making every effort to, but the manufacturing of this air bearing and operation are all very expensive, because because surrounding air contains fiber and especially makes maintenance cost very high, and each single spinning position all requires to supply with compressed air, therefore total energy consumption rising.The locational requirement of horizontal direction of air bearing that surrounds funnel in addition is also bigger.Propose to use the another kind of solution of at least a magnetic bearing as the funnel supporting in DE 44 22 420 A1, this bearing can be regulated on one's own initiative by means of a sensor.Therefore funnel is the ground magnetic bearing that freely suspends.Though magnetic bearing has satisfied the requirement of speed stability, simultaneously bearing drag is very little again, and is just much complicated on magnetic bearing initiatively and the rolling bearing structure compared, makes also very expensively, and must will power also to have the electronic control system of costliness.Therefore but textile machine is mainly used in the low-wage country and high-quality attendant is also very limited, this complex structure and can only almost can't being applied in practice by the solution of professional's periodic maintenance.
Another kind possible with known bearing and drive unit in the supporting and the drive unit of funnel all be to be undertaken by a hollow shaft, this hollow shaft is connected in the funnel upper end coaxially, and makes yarn guide funnel into by means of this hollow shaft.Funnel be cantilever support and can be free approaching, therefore not only on the inner surface of funnel, and on its outer surface can directing thread.Because supporting and driving are all undertaken by hollow shaft, and the diameter of hollow shaft is more much smaller than the diameter of the funnel that covers spindle, therefore can realize high relatively funnel rotating speed by means of rolling bearing.But the funnel of elongation constitutes a big lever arm concerning bearing, therefore minimum imbalance on the funnel, for example produce owing to pollution or yarn tension, can cause very big vibration, it has just limited maximum accessible funnel rotating speed and has quickened wearing and tearing significantly.Between the parts that rotate and fix, especially the rotor of electric driver and all contacts between the stator all must be avoided in any situation, because this may cause the destruction of member.
Described a kind of so-called cap spindle yarn device that can drive the bell-shaped piece that maybe can brake that has among DE 34 00 327 A1, wherein yarn has been enclosed around and tie and flow to spindle in the outside of bell-shaped piece.Bell-shaped piece by two single-row rolling bearing fixed-site on the axle of a upper end that is connected in its handle, thereby rotatably be arranged on the fixed position on the frame of cap spinning spindle device, these bearings on axle and also their interior ring with spool fixedly connected.Axle has a vertical passage, and this passage has an outlet under the bearing that is positioned at bell-shaped piece shank upper end and is used for yarn is directed to the bell-shaped piece outer surface.Bell-shaped piece is realized driving by a motor, and the rotor of motor is fixed on the end of leaving funnel of axle, so the whole supporting of bell-shaped piece, axle and rotor all occurs between rotor and the funnel.The stator of drive unit links to each other with the frame of weaving loom.Bell-shaped piece is surrounded by a motionless openable outer cover with little air gap.Another kind of outer cover is designed to one with the outer cover of bell-shaped piece in one embodiment, and it surrounds spindle.The words of these two kinds of outer cover necessity can be open for the operation on winding reel, as getting rid of broken yarn, perhaps are used for substituting full winding reel by the winding reel of sky, and its method is that they especially are designed to is openable.Make bearing diameter less than at a kind of bearing that surrounds funnel by the layout of bearing on axle, thereby can realize the bell-shaped piece high rotational speed.But because this must not be less than the minimum diameter of regulation, so that make the bell-shaped piece of the length of cantilever support can realize vibrationless, reliable supporting, the rolling element raceway of the single-row rolling bearing of therefore pushing to has relatively large diameter still for the rotating speed of pursuing and the spacing of two single-row bearings still shows the obstacle of the bell-shaped piece rotating speed of being pursued.The wearing and tearing that cause in addition are also just relatively large, for fear of this situation, the limit just brought up in the requirement of product precision, and this makes the expense of manufacture process very high again.Bell-shaped piece and bearing fast and and uncomplicated dismounting, be impossible especially for the purpose of safeguarding because two single-row bearings must subtend clamp mutually assemble and also the dismounting of bearing very bothersome.Each bearing forms self a lubricating cavity, therefore two bearings is lubricated dividually.Must make rotor leave axle in addition so that take out funnel.The solution of effective vibration damping vibration damping of whole device is not described.
WO 2004/076727 A1 discloses a kind of device that is used for coil spinning or twists thread, and it has the mitriform circle cover of taking offence, cylindrical parts that diminishes gradually that constitutes axle of its tool.Axle is rotatably mounted by means of two bearing row by a bearing block.Between these two bearing row, be provided with an asynchronous motor.Bearing block and motor are arranged in the shell that is fixed on the bearing supporting disk.Such bearing-driving combination is very complicated in actual applications, because bearing and drive unit combine forcibly, and two bearings must be by fixing drive unit shell mutually facing to clamping.In a kind of such structure, just must take drive unit apart in order forcibly rolling bearing to be carried out regular maintenance.This has just improved maintenance cost greatly.Each bearing forms self a lubricating cavity, and two bearings can be lubricated dividually.The effective measures that are used for necessary vibration damping are not described.
Summary of the invention
Thereby task of the present invention provides a kind of funnel unit with the drivable funnel that maybe can brake, by means of this funnel unit can be low in the relatively simple and compact wearing and tearing of structure, realize higher funnel rotating speed when safeguarding simple and as far as possible little energy consumption.
This task is by realizing that characteristic features solves described in the independent claims.To the present invention with substitute or favourable mode carry out improved those features and see dependent claims.
The present invention points out: by arranging a bearing in the cartridge housing between rotor and funnel compactly, and by in the common vibration outer cover, the funnel supporting disk of rotary part, fixing driving element and cartridge housing and funnel unit and the parts that all the other are motionless being isolated, favourable widely owing to vibration characteristics so, but just can when guaranteeing funnel unit less wearing and tearing, low energy consumption and disassembled simply, realize higher funnel rotating speed.
The present invention both can be applicable to spinning machine in principle, also was used for braiding machine, the basis of described task above this forms.If below address spinning machine and spinning process, so always also can comprise the twisting machine and the process of twisting thread.Well-knownly concerning the professional be: such process from the principle for example also can be with twine, fill strand twist thread (false ply yarn), core-spun yarn or bag core twine, yarn or fancy twine and other process deformation program and relevant ground with process is no matter described or implement on opposite materials flow direction, so so-called coiling yarn also can be regarded as the output yarn in scope of the present invention.
Have many different notions to be applied to funnel spinning or similar approach in the literature, for example bell yarn spins, the spinning with the air ring cover, cap spinning spindle, flyer spinning and other title.But the present invention not only is confined to the funnel spinning, and usually refer to spinning, twist thread or rewinder, in these devices one rotatable, can directing thread, be essentially rotational symmetric yarn guide member or air ring cover member can comprise one equally also rotatablely be used to spin, a reel for yarn of the spindle of twist yarn or after-combustion is around the position or yarn position (hereinafter referred to as reel for yarn around the position).
According to the funnel unit that is used for spinning apparatus of the present invention have one drivable, have the spindle of a reel for yarn around the position, it can be arranged or be arranged on the funnel supporting disk of spinning apparatus.Funnel unit have one be designed for cover in one heart reel for yarn around the position, can make yarn preferably to the inside or the rotatable supporting and the drivable funnel of guiding to the outside in case of necessity, funnel also can have all shapes that are fit in addition arbitrarily except a kind of funnel shaped.The axle of a rotatable supporting has one and is used for yarn being delivered to the axial thread guide eyelet of funnel and being connected coaxially with funnel un-rotatably, by this funnel cantilever support and can drive maybe and can brake rotatably.The axle with funnel or by two interconnective, can constitute or be designed to one by the parts that different corresponding suitable materials is formed.The driving of funnel or braking are undertaken by an electric driver, and the rotor of this drive unit is especially by means of bonding or shrink and be fixed on the axle, and its stator is surrounded by a drive unit shell.Electric driver for example is designed to a kind of asynchronous machine or a kind of synchronous motor.Bearing unit be arranged in one with cartridge housing that the drive unit shell is connected in and on the rotor and the axle between the funnel of drive unit, so funnel and rotor cantilever support rotatably.So-called bearing unit generally is meant a kind of being used at least radially and the also member of bolster axially preferably.Cartridge housing, it for example can have a kind of closure, the shape of cylinder blanket or a kind of tong-like holder especially, it generally is the support of bearing unit.Bearing unit is designed to have the double-row bearing of two rolling element row in a kind of improvement project of the present invention, ring constitutes the axle of the water jacket of rolling element guiding by having two in it.Axle is made by a kind of material that is suitable for the rolling element guiding in this embodiment.Because rolling element directly rolls,, therefore can when less frictional resistance, realize bearing high rotational speed stability so that the diameter of two rolling element raceways is compared with the rolling bearing on being contained in axle is just much smaller in the groove of axle.The outer shroud of double-row bearing is designed to the bearing insert of an especially columniform length in another kind of improvement project of the present invention, and it has two inside grooves and is used for the rolling element guiding.Bearing insert is surrounded and is attached thereto by cartridge housing, especially releasably.Just funnel and axle and whole bearing unit can be separated with the funnel unit that is left by the connection that separates between bearing insert and the cartridge housing.This in addition can not remove rotor from axle and carry out, if the outside of bearing insert (as improving in the design at of the present invention) is greater than the maximum outside diameter of rotor and can make rotor axial pass cartridge housing, so funnel, axle, rotor and bearing unit as a common funnel by along moving axially and separate on the funnel direction with the funnel unit that is left.This has very big advantage: the maintenance of a whole set of bearing and replacing can be taken a lot of work and be realized in the shortest time very much.Available another kind of funnel is changed a funnel, for example for spinning machine is transformed by another kind of spinning method, also can finish at short notice.Because double-row bearing constitutes the unit of a sealing, therefore two rolling bearings just can be with a common lubricating cavity to external seal, and this makes maintenance much easier.Funnel and remaining funnel unit for example separated carry out by means of the screw of a direct radial finger on the direction of axle, therefore its approaching easily from the outside also engaging-in recess that forms in the bearing insert has just avoided funnel to produce slip or rotation with respect to remaining funnel unit when screw-driving.The plastic hoop that firmly surrounds bearing insert is for example as receiving member, in screw can engaging-inly should encircle.
According to funnel unit of the present invention have one with funnel supporting disk attachable or that be connected, especially columniform outer cover at least indirectly, this outer cover surrounds cartridge housing at least with one heart spaced radial.Outer cover is isolated to turn up the soil by the damping component of the radial and axial at least maintenance spacing that works with cartridge housing and is connected, thereby make the remaining part of funnel, axle, rotor, drive unit shell, stator and cartridge housing and device at least, particularly outer cover and funnel supporting disk are kept apart, thereby do not transmit or transmitting vibrations partly just.The vibration performance that this has just improved funnel unit greatly can reach higher funnel rotating speed, cuts down the consumption of energy and improve the process security.Damping component for example is designed to two damping components, and they surround cartridge housing substantially annularly on the axial height of two rolling element row.The rubber hardware or other the elastic damping spare of vibration damping, for example rubber grommet, plastic hoop or foamed material ring all are suitable as damping component.Also can use a plurality of independent parts that distribute round cartridge housing if need not encircle that.These rotating members are especially by funnel, axle, the parts of rotor and bearing unit constitute, because these rotating members and direct and the synergistic fixed component of these rotating members, especially the stator of drive unit and the cartridge housing that is connected with the latter have constituted a mutual coupling connection mutually, as far as possible little and light vibration unit, thereby avoided the relative vibration between rotating member and said fixing member, thereby avoided rotor in stator owing to undesirable vibration causes radial motion, even may avoid a kind of contact of disturbing drive unit between rotor and stator.In the junction between this vibration unit and the static bearing unit of keeping apart with it by constituting at bearing insert with damping component between the outer cover that the funnel supporting disk is connected.Outer cover or as the junction between damping component and the funnel supporting disk, perhaps in another kind of improvement project indirect of the present invention or directly exercise another kind of function, preferentially be shielding function, its method is to make outer cover vertically arrange and surround substantially concentricly the whole length of funnel along funnel.Outer cover for example has a cylindrical outer surface and an inner surface that adapts to the funnel external surface shape at least in part.What cylindrical outer surface can be used as cylindrical shading member receives the appearance part, and it can move towards the spindle direction on outer cover in order to cover spindle.Outer cover can be designed to single-piece or many and for example can open surrounding in the position of funnel.
Description of drawings
Below the specific embodiment that just schematically illustrates with reference to the accompanying drawings describe in detail as an example purely according to device of the present invention, other advantage of the present invention is wherein also described.Be depicted as in detail:
Fig. 1 has a kind of embodiment according to funnel unit of the present invention of damping component and dismountable funnel;
A funnel of forming by funnel, axle, rotor and bearing unit of the funnel unit that Fig. 2 is shown in Figure 1.
The specific embodiment
Because Fig. 2 illustrates a part among Fig. 1 representing clearlyer, therefore followingly just these two figure are illustrated together.Fig. 1 has schematically represented to be used for a kind of possible embodiment according to funnel unit of the present invention of spinning apparatus purely, this unit includes a drivable individually spindle 2 and is used for receiving yarn at a reel for yarn on position 1, and Fig. 2 then schematically illustrates the funnel 21 of separating with remaining funnel unit.Spindle 2 and funnel unit are implemented axially-movable mutually in known manner.The 1 outer cover surface that is for example surrounded by that yarn 27 of having been reeled by (as shown in Figure 1) at least in part of spindle 2 constitutes the reel for yarn of spindle 2 around the position.Yarn is wound on the sleeve 26 with a kind of form of cop in the embodiment shown, and this sleeve is inserted on the spindle 2.Funnel unit has a funnel 4, and funnel has a cylindrical basic shape and the end that taper enlarges.Scheme especially also can make whole funnel 4 be designed to cylindrical or conical or make funnel 4 have other any suitable shape in the enforcement spinning method as an alternative.Funnel 4 is connected with axle 6 un-rotatably.On axle 6, be provided with the thread guide eyelet 5 of the central authorities of a perforation, make yarn enter funnel 4 by this hole and also on the inner surface of the funnel 4 that rotates, be directed to a thread-carrier 28 there, this thread-carrier for example is designed to an eye, the base until the end of the conical expansion of funnel 4.This yarn for example can pass an opening in guiding or form a circle on the funnel base to the outside on the correct position in a replacement scheme that herein is not described in detail.Just twist in one heart on the spindle 2 by funnel 4 and in known manner yarn to be wound up.Funnel 4 and axle 6 are expressed as a common means in an illustrated embodiment.But axle 6 and funnel 4 can be designed to two-part construction, they are respectively made by the material that is fit to.Axle 6 drives by a rotatably radial and axial radial support of bearing unit 12 and by a drive unit 7 that is designed to motor, and rotor 8 nothings of drive unit are contained on the axle 6 with relatively rotating.Connection between axle 6 and the rotor 8 for example can realize by bonding, bearing unit 12 is made up of two rolling element row 23a and 23b, cylinder-shaped bearing lining 16 and two water jackets 15 that directly grind on axle 6 with two inside grooves 17, and these two rolling element row 23a and 23b roll in groove respectively.The effect of ring in therefore axle 6 plays, bearing insert 16 is then as outer shroud, because raceway just directly grinds for 16 li at axle 6 or bearing insert.Because rolling element is guiding on axle 6 directly, so bearing diameter is as much as possible little, therefore can reach high bearing rotating speed.Because described bearing unit 12 is arranged in axle 6 the section that rotor 8 is housed and is adjacent between the section of funnel 4, so funnel 4 and rotor 8 are cantilever support.Bearing insert 16 equally also is that the cartridge housing 11 of cover tubular encloses with gap or interference fits and encases by one.In order to stop bearing insert 16 and therefore axle 6 endwisely slipping with respect to cartridge housing 11, be provided with a kind of releasable connection, preferably at 11 li pinching screws 24 that point to axle 6 of cartridge housing, this screw engaging-in one by 22 li on the material that is fit to, ring that for example POM (polyformaldehyde) makes, this ring is fixed in the center annular groove of 16 li of bearing inserts, makes this lining indeformable.The stator 10 of drive unit 7 is positioned at 9 li on a drive unit shell, by this shell stator 10 is connected with cartridge housing 11.Drive unit shell 9 and cartridge housing 11 are one in an illustrated embodiment.It can certainly be the structure of many bodies.
Because bearing unit 12 and drive unit 7 are by damping component 14a and 14b and outer cover 13 and funnel supporting disk 3 uncoupling in vibration, thereby improved the vibration performance of funnel unit greatly, thereby can realize high funnel rotating speed, little vibration and change little energy demand.
The outer diameter D of bearing insert 16
16Design greater than the maximum outside diameter D of rotor 8
8, so rotor 8 can axially pass cartridge housing 11 guiding.By means of the connection between axial releasable bearing insert 16 and the cartridge housing 11 by unclamping pinching screw 24, therefore just can be with funnel 4, axle 6, rotor 8 and bearing unit 12 as a common funnel 21 by funnel 4 is moved axially and separates simply with remaining funnel unit along direction 25.This especially for implement to bearing unit 12 or drive unit 7 periodic maintenance, for cleaning funnel 4 or for changing whole funnel 21, for example all highly beneficial when the conversion spinning method, because just can take off whole funnel 21 by unclamping a pinching screw 24.Therefore avoided the unnecessary dead time of spinning apparatus, therefore except making productivity ratio can also save other expense relevant improving greatly with maintenance owing to can realize higher funnel rotating speed.
Funnel unit is characterised in that, funnel 4 is together with drive unit and the bearing unit 6,8,9,10,11 be made up of axle 6, rotor 8, shell 9, stator 10 and cartridge housing 11, and by damping component 14a, 14b links to each other with outer cover 13 and therefore flexibly is installed in the outer cover.
