Description
Technical field
The present invention relates to the device of a kind of coil spinning or circle twist yarn (loop twisting), this device comprises the air sphere limiter (balloon limiter) of the spindle of a perpendicular and and the coaxial installation of this spindle, and this air sphere limiter is used for line is transported to and is installed in the hollow shaft that rotates on the spindle.
Background technology
Said apparatus is a kind of variation scheme that is used for coil spinning or circle twisting apparatus according to patent EP 0883703B1.Described air sphere limiter is a tubulose, has a lower end enlarging, and it is rotatably installed, and drives as spindle in operation.In operation, the line that is transported is subjected to centrifugal force pulls, moves along its inner surface, and then under the effect of winding tension, line transits directly to from inner surface on the hollow shaft on the spindle that is installed in rotation.Because the rotation of air sphere limiter and spindle, promoting line also rotates around the longitudinal axis of spindle, like this when the inner surface from air sphere limiter carries out the transition on the hollow shaft, form the expansion coil of a rotation, this coil nestles up air sphere limiter lower end (being also referred to as out end) and rotates, and this coil is to control the tension force of line with mode like the steel wire lopps of coil spinning device or twisting apparatus.For the rotating coil that keeps launching advantageously rotates continuously with the speed lower than spindle, should brake the rotation of this coil.According to above-mentioned patent description, for example the size of upwards launching coil by the limiting wall diameter that does not move limits, this wall is with the interval of regulation, around and the air sphere limiter of overlapping go out end, the expansion coil opposite curvature of this rotation contacts with this wall, or/and by a guide edge that is used to be wound line, this guide edge is that the longitudinal axis that does not move and center on spindle is installed under the air sphere limiter equally, and the inferior division of expansion coil that leads to the rotation of hollow shaft contacts with this guide edge.
On this device, can make the high-quality line at a high speed.The but friction of the expansion coil that must consider rotate and air sphere limiter increase, this in addition can cause mutual infringement.For several lines, the line that makes by thermoplastic fibre particularly, the above fact even mean a kind of restriction that is difficult to overcome fully, even use limiting wall to overcome with shiny surface, the zone of this shiny surface from first contacting with line, towards the direction of lower end, away from the longitudinal axis (EP0933454) of spindle.Show any tension force that all can increase line unfriendly that contacts between the expansion coil opposite curvature of rotation and the limiting wall in addition.Therefore, when by being installed in below the air sphere limiter and the guide edge of the expansion coil inferior division that influence is rotated and limiting wall and when the expansion coil that rotates braked, also need consider between guide edge and the reciprocating spindle and can relatively move, this makes that the size of the coil of wire repeats to change regularly on the guide edge, and then line tension changes.Even line tension changes little, but under many circumstances, the scope of application of this device that also can cause damage, thereby restrict when especially preparing than fine rule.Brake the expansion coil of rotation if only use guide edge, then not only must consider the variation of above-mentioned line tension, but also need to consider corresponding centrifugal force under the high process velocity, this centrifugal action is on the expansion coil (between the guide edge of air sphere limiter and brake line) that rotates, cause the radial dimension of the expansion coil of rotation unacceptably to increase, and then this line that undesirably stretches.Also relate to restriction in the case to several lines.
Summary of the invention
The objective of the invention is to, design device described above like this, make this device can prepare the high-quality line, and do not have above-mentioned restriction with higher process velocity.
According to the present invention, this purpose realizes by a kind of air sphere limiter, this air sphere limiter is formed with the contactless lower part that is connected and does not rotate, this top with one with the top of the same rotating drive of spindle by one, wherein this lower part has the spigot surface that is used for line, and this line begins and finishes in its lower surface at the inner face of spigot surface.
Because this layout, directly below the lower part that air sphere limiter does not rotate, form a coil that freely rotates fully, the spigot surface that the rotation of this coil meets on the lower part of not rotated by air sphere limiter the destination is braked, so this coil itself can control line tension force.The braking action of the spigot surface on the lower part that air sphere limiter does not rotate also shows energetically, this braking action is with winding tension, can keep the needed diametrically functional dimension of expansion coil of rotation, like this, no longer need to adopt other measures for this purpose.On this device, can produce different types of line now, and not previous inevitably restriction.And can make such line, because the lower part that air sphere limiter does not rotate, the outer fiber of this line is arranged better, makes this line have higher quality, particularly with regard to fluffing property.
Show in addition, process velocity can also further improve, because the top that air sphere limiter rotates is littler than the radial load of previous integral type air sphere limiter, and, centrifugal force component on the expansion coil that rotates is absorbed by the bottom branch that air sphere limiter does not rotate at least in part, and under integral type air sphere limiter situation, the centrifugal force component acts on out end by the expansion coil that rotates with whole weight, thereby tends to remove from the longitudinal axis going out end.
Other advantageous embodiment of the present invention are provided by dependent claims.
Description of drawings
Accompanying drawing is exemplarily represented embodiment of the present invention.Fig. 1 represents the side view of apparatus of the present invention embodiment, and the partial cross section of Fig. 2 presentation graphs 1, Fig. 3 are represented the partial view of another embodiment of apparatus of the present invention.
The specific embodiment
Fig. 1 only represents a kind of device that is used for coil spinning or circle twist yarn.In corresponding machine, a plurality of such devices can be set as operative position respectively in one or two vertical side.These devices comprise a draw-gear that is used for filament or rove, and perhaps a feeding device that is used for multi-thread system depends on whether this device is to be used for coil spinning or circle twist yarn.From angle of the present invention, these devices respectively comprise a feeding device 1 that is used for the fibrous material 2 that spun or twist with the fingers.Below a pair of feeding device 1 that transports roller 3 expression, the vertical spindle 4 and the coil of wire 6 with hollow shaft 5 of installing, and the air sphere limiter 7 coaxial with spindle 4, this air sphere limiter are used for line P is fed to hollow shaft 5 on the spindle 4 of rotation in Fig. 1.A cable guiding device 8 is housed between feeding device 1 and air sphere limiter 7, is used for line P is adjusted the longitudinal axis 9 that enters air sphere limiter 7 or spindle 4.In another unillustrated the present invention program's embodiment, feeding device itself also can be used to adjust line, for example installs so for this purpose, makes the following position that roller occupies cable guiding device of transporting, thereby replaces it fully.
Spindle 4 forms the rotor that is installed in the motor 10 on the roving frame 11.Roving frame 11 extends to all operations position of machine, in order to form the new coil of wire 6, for it is equipped with common programme controlled driving (not shown), moves thereby can rise and descend on double-head arrow 12 directions.Perhaps, obviously also can in a known manner this spindle rotation be installed on the similar roving frame, this rotates by the conduction of tangent line band, and it extends to all operations position (not shown) of machine equally.
Described air sphere limiter 7 is made up of with the contactless lower part that is connected 14, this top with one a top 13.This top for example is bell shape or ampuliform, and it has the continuous surface 15 that contacts with line P, and towards going out end 16 coniform broadening.Going into the part formation axle 18 that shrinks on end 17 sides, by this axle, this part is installed in the bearing group zoarium 19 rotationally, and is driven by electric asynchronous motor 20.This bearing group fit 19 and this motor 20 are contained in the housing that is fixed on the supporting base 21, and this will be in following detailed description.Be similar to roving frame 11, this supporting base 21 is contained on all operations position of machine, is that with roving frame 11 differences this supporting base is motionless.
Lower part 14 (see figure 2)s of air sphere limiter 7 are the shape of ring 26, and are connected with the end 16 that goes out on top 13 at its end face.This part 14 has the rotation guide surface 22 that is used for line P, and this line face within it begins, and finishes in its lower surface.In this embodiment, spigot surface 22 is alternatively towards the longitudinal axis 9 direction bendings of air sphere limiter 7 or spindle 4, with the longitudinal axis 9 rectangular planes of air sphere limiter 7 or spindle 4 on record minimum diameter A, less than the maximum gauge B of the inner surface 15 on air sphere limiter 7 tops.Spigot surface 22 is the shape of full curve, but also can have other shapes if desired, for example as the part of corrugated tube outer surface.The whole lower part 14 of air sphere limiter 7 or at least its part that contacts with line can make by commercially available tool steel, not only can machining or make by accurate autofrettage, also can and carry out spigot surface 22 high polish subsequently by die forging.But, in order to improve service life, spigot surface 22 should be made by wear-resisting especially material (for example industrial ceramics) at least.
For position relation firm between the top 13 that keeps air sphere limiter 7 and lower part 14 (Fig. 1), lower part 14 is installed in support 23 inside, for example connect or connect by anchor clamps with reference to descriptions such as following Fig. 3 by spiral, this support such as same pipe, surround air sphere limiter 7, promptly, not only surround its top 13, also surround its underpart 14, and this support is fixed on the supporting base 21 with its upper end, and this support 23 also forms the housing of bearing group fit 19 and motor 20 on the top 13 of air sphere limiter 7.
In operation, the top 13 of air sphere limiter 7 and spindle 4 the same being driven (Fig. 1 and 2) with coiling hollow shaft 5 and coil of wire 6 (on this hollow shaft 5).Line P is transported on the hollow shaft 5 by air sphere limiter 7 or on the coil of wire 6 on this hollow shaft 5, this line is promoted by the pressure of centrifugal force, at first the inner surface 15 along the top 13 that air sphere limiter 7 rotates moves, and the spigot surface 22 along non rotatable lower part 14 directly is directed on the hollow shaft 5 or the coil of wire then.Because the top 13 of air sphere limiter 7 and the rotation of spindle 4, so line P is pushed, equally also the longitudinal axis 9 around spindle 4 rotates, like this, when carrying out the transition on the hollow shaft 5 or the coil of wire 6 in lower part 14 from air sphere limiter 7, form the expansion coil Ps of a rotation, this launches directly rotation below air sphere limiter lower part 14 (Fig. 2) of coil.Because launching coil Ps is fully freely, so the tension force of itself control line P, like this, the change of the coil of wire 6 diameters is responded, the footpath upwards size of tension force also changes automatically, thereby the size that acts on superincumbent centrifugal force also changes.Act on the expansion coil Ps of rotation centrifugal force with useful mode also Support Line P carry out the transition on the spigot surface 22 that air sphere limiter 7 do not rotate lower part 14.Simultaneously, the spigot surface 22 expansion coil Ps that also influence is rotated as brake component, in this way, the expansion coil Ps of rotation also is braked when rotating around the longitudinal axis 9 of air sphere limiter 7 or spindle 4, makes its velocity of rotation always advantageously be lower than the velocity of rotation of spindle 4.The braking action of spigot surface 22 needn't be big especially, because when rotating for the expansion coil Ps that rotates for the required deceleration, as long as there have fraction kinetic energy to be absorbed by the friction on the spigot surface 22 to be just enough.And, by this braking action,, also keep the size that the expansion coil Ps of rotation works diametrically in conjunction with winding tension.When on hollow shaft 5, twining,, line P is transmitted on the coil of wire 6 along hollow shaft 5 by roving frame 11 moving up and down on double-head arrow 12 directions carried out common programme-control.
In illustrated embodiment, the minimum diameter A of air sphere limiter 7 lower parts 14 spigot surfaces 22 is less than the maximum gauge B of air sphere limiter 7 top inner surfaces 15.Therefore, centrifugal action is absorbed by air sphere limiter 7 non rotatable lower parts 14 on 7 of air sphere limiters at the component on the expansion coil Ps that rotates, and air sphere limiter 7 has only the top 13 of slight radial load, is controlled by an energy input, is enough to keep given service speed.Be not subjected to line P yet and rub by force because air sphere limiter 7 tops 13 go out end 16 at it, so this part 13 also can be by very light and have the material of less resistance to make to the wearing and tearing of line P, for example make, but also can make by suitable industrial plastic material relatively cheap and that be easy to process by duralumin.Obtain low-quality air sphere limiter 7 tops 13 by this design, in harmonic frequency is shifted to the scope of higher operation revolution, improved its dynamic performance.Bearing group zoarium 19, wherein be equipped with air sphere limiter 7 tops 13 the axle 18, the quality of a load self rotor, from service life angle see that this is favourable.
Fig. 3 partly represents another embodiment of the present invention, supposes that at this other unillustrated assemblies are identical with assembly shown in Figure 1.As shown in the figure, air sphere limiter 7 lower part 14a are part cylindrical tubes, and this part 14a has can make its interval that moves freely, this part 14a coaxial around and the top 13 of the air sphere limiter 7 of overlapping.This part 14a is similar to the lower part 14 of air sphere limiter 7 among Fig. 1 and 2, and a spigot surface 22a is also arranged, and but, face is as interior cylindric beginning within it for this spigot surface, and the nose circle in the lower surface as the pipe adjacency finishes.This part 14a is contained among the support 23a movably, and the design of this part is equivalent to the support 23 of air sphere limiter lower part 14 among Fig. 1.Difference only is that the lower end of carrying air sphere limiter 7 lower part 14a forms the microscler closing sleeve that groove is arranged, and has the end folder 24 that radially protrudes, and by screw 25 or other known securing members it is pulled in together.
Certainly, also can use the support 23 of carrying lower part 14 in the similar fashion installation diagram 1.Therefore, in any case can not exhaustive air sphere limiter 7 lower parts 14,14a possible installation and fixed type in support 23,23a.Importantly find a kind of mode that can guarantee fixed position relation between air sphere limiter 7 lower parts and the top under every kind of situation, simultaneously, can guarantee that the lower part that lower part of air sphere limiter and another for example are suitable for another kind and/or fineness line P exchanges, and with respect to air sphere limiter 7 tops 13 go out end 16, also as much as possible axial adjustment air sphere limiter 7 lower parts 14,14a go out end 26,26a.
