Description
The present invention relates to a kind of cooling and oiling device of melt-spun fibre, this device has the quenching rod (filter stick) and the collating unit that is referred to as the center chilling apparatus that are arranged on circular fiber array center.
The center chilling apparatus illustrates and describes with being enumerated, its possibility of its application is by briefly at " chemical fibre/textile industry " (Chemiefasern/Textilindustrie in the 42/94th year in June, 1992,42th/94th year, June 1992) " producing the present situation and the trend of melt-spun synthetic fiber technology " business publication in mention.
An important composition of center chilling apparatus is a collating unit; in preparation, adopt this device; new spinning, producing for the first time mechanical mobile polymer fiber that contact with place after the cooling duct with fibre guide spare by quenching; promptly carried out stabilised finish and humidification, so that the surface of protection fiber is not subjected to dry friction and be further to handle the water that provides suitable and the coating of oil by the spin finish of annular gap ejection (contain usually have an appointment 99% water).
The prior art that is provided with about the position of the collating unit of center quench system is at the public publication 3 of German patent application, 629,731A1 and 3,708 has done the description of relevant function and art designs among the public publication WO92/15732 of 168A1 and patent application.These publications disclose with collating unit be designed to have at least one around the outstanding lip of ring-shaped pottery coating in annular opening gap.Therefore such collating unit also is referred to as a kind of preparation ring.The improvement of this structure can be such, that is, some are widened in the gap of annular also fill a kind of material that permeates spin finish solution, and perhaps, the contact surface at outstanding lip edge is replaced by a kind of narrow sintering metal ring.In continuous running, the supply of spinning finisher solution comes from a metering supply pump, this metering supply pump is in the outside of center chilling apparatus, its supply is the inside that is fed to collating unit by service, thus, spin finish is also taken away by fiber by distribution radially thus by the annular gap or the radially outer gap of level.
German patent publication thing 2,919,331 discloses a kind of spinnerets with a device that oils continuously on the exit face of spinnerets.Aspect this, spin finish being applied on the fiber of spinning does not become a problem, but have silicone oil spinnerets exit surface dewing and wetting be a problem.This situation is to occur when preventing to adhere to the melted material drippage on the spinnerets and preventing sedimental formation.For this purpose, a dull and stereotyped part that divides has been installed on spinnerets, it can be a kind of sheet metal or filter screen of perforation, and this thin slice or filter screen keep otch moistening and that have some to be stamped by the silicone oil of supplying with by supply pipe near spinneret orifice.Because this otch is arranged, therefore, the fiber of spinning just might have no obstacle ground to be passed through.This publication basic just not relevant be equipped with a kind of do not guarantee with that spin, that contact with the fiber direct mechanical of high-speed motion, after cooling off, make spin finish be coated in any suggestion of the device on the fiber equably with constant spacing and time.
About spin finish is coated to speed (all being represented by percentage by weight % for water and oil) on the fiber, an optimum range is all arranged in all cases, this scope is applicable to the condition of work of spinning process, product, existing machine and producd fibers long filament, except the various conditions that other will keep, also has the fundamental of a kind of failure-free operation and high-quality product.Under given condition, spin finish is approximately proportional by the coating rate of the hoop fibre applicator that oils for the fibre weight in the integral body of a spinning unit production, perhaps, proportional with the whole polymer melt of each spinnerets that passes through the center chilling apparatus respectively.
In 1992, be used to produce the ability of the quenching spinning unit, center of polyester fiber, as the business publication of " chemical fibre/textile industry " in the 42/94th year in June, 1992 of originally mentioning is seen, be 2kg/min.For industrial production, as by W.Stibal (EMS-INVENTA AG) in 3-5 day in November, 1997 the name of holding in the relevant special topic of " polyester chain " on the world conference of the PET ' 97 of Zurich, SUI is called described in the lecture of " EMS technical partner ", this is the limit that is limited up to institute's accepted standard equipment in 1996.In 1997, the output of 3kg/min became possibility, and the output of 4kg/min in 1998 is tested in bench-scale testing.This development is represented by Figure 20 of the text of teaching materials.As from can seeing figure and its commentary, all must correspondingly increase the diameter of quenching rod and last oil ring for the increase of output each time, promptly, not only because the bigger diameter of spinnerets, but also because the increase of capacity will mean the increase of ratio of required quench air (being used for the cooling and the curing of spinning fibre) and the increase of required spin finish, and, even the output that itself is increased also requires to making single fiber always with approximately identical speed and the required bigger diameter of supply on approximately identical specific area.
More particularly, yet, adopt big under the situation of oil ring, guarantee spinning arrangement solvent on the whole circumference of last oil ring even distribution with more and more difficult.Spin finish is pumped into the center of collating unit from the annular gap that whole circumference is all opened by the pump of spin finish, under the situation of the radially fault of spinning arrangement solvent streams, uneven distribution can appear, this possibility pockety will increase along with the increase of its diameter, but this possibility even under than the situation of minor diameter, also can occur.In this respect, the little error of the width of annular gap, non-level position of this ring or under some occasion, lack uniformity in the spin finish (this finishing agent also is regarded as emulsion sometimes) and all can play a role.Therefore, although in conventional design, might by guarantee with a kind of cleaning and uniformly solution, by production have the equipment of the minimal tolerance of annular gap, by accurately adjusting horizontal level, by satisfied, very accurately prepare spin finish and reduce these disturbing factors, but, if these factors occur, more or less, this system is always keeping the sensitiveness to described disturbing factor.
Under the situation of local fault environment, on last oil ring circumference, the spin finish that is coated on the fiber can be inhomogeneous, and this coating also can cause the operation of jolting of fiber, and produces the very big distribution of spinning fibre qualitative data.Having under the situation of many interference, for example, if last oil ring is level and/or in the annular gap no longer, the fluid passage is subjected to partly because the obstruction of the deposition that contaminated spin finish solution forms, perhaps even the words that stop fully, just existence no longer includes liquid and goes up the possibility that oil ring moves at the contact interface with fiber with dry state from the possibility and the existence of the ejection of corresponding annular zone.Except producing direct mechanical friction (this friction will cause serious breaking-up under the situation of middling speed or high draw speed) to fiber, this result will influence production, even interrupt in feasible the production, because be converged into the single silk thread that passes through the center chilling apparatus of a yarn or a branch of yarn, no longer closely flock together, but exist with the form of special wet bundle yarn on the one hand, and exist with a kind of multi cord loose, that do or the form of yarn bundle on the other hand.Such fibre bundle very likely is wound onto on the next production equipment of rotation at a high speed.Carry-over pinch rolls can preferentially snarl and carry any super wet fiber, these fibers are owing to scribbling the adhesion that becomes of too much oil, and in addition, under the situation of producing staple fibre, the single fiber of doing that stretches out will tend to be twined by the so-called sun gear on receiving tank, if transport is not braked immediately, even can cause the fiber in whole jar to be drawn out.
An object of the present invention is to increase the reliability of center chilling apparatus and guarantee spin finish, and only need a subsidiary measuring pump that is used for spin finish and a service around the more uniform distribution of the circumference of last oil ring with collating unit.
This purpose is used for quenching and the device that the melt-spun fibre fiber oils is realized by such, this device has the quenching rod (filter stick) and the collating unit that are arranged on fibrae circulares array middle part, this collating unit is by a service, from a subsidiary spinning arrangement measuring pump, be provided with spin finish, and it is wetted when fiber passes through from an annular gap, this collating unit is divided into the circular segments of same size, these circular segments are had the fluid distributing element that is arranged on this section upstream according to ring-type setting and collating unit, the spinning finisher solution that flows that this fluid distributing element will come from service equably is assigned on all sections, and spin finish passes the annular gap thus.
And the number of the described section of collating unit can be between 6-48.
And fluid distributing element can be made of the fluid metering nozzle of precision.
And, being in operation, the pressure differential of passing accurate fluid metering nozzle is in the scope of 0.03-0.50bar.

Referring now to special embodiment the present invention is described.
Fig. 1 shows a total schematic diagram of collating unit of the present invention.
Fig. 2 illustrates one embodiment of the present of invention as a kind of mechanical modification of collating unit of the present invention.
Fig. 3 and 4 shows the improved embodiment in hydraulic pressure aspect of collating unit of the present invention.
The present invention is schematically shown by aforesaid Fig. 1 generally.In this respect, the implication of reference number is as follows:
1 is used for the measuring pump of spin finish.
2 be used for spin finish service.
3 collating units.
The fork of the fluid of 4 spin finishs.
5 fluid distributing elements.
The section of 6 collating units.
The interval of 7 sections.
The measuring pump 1 of the spinning finisher solution of constant flow rate from being used for spin finish is provided to collating unit 3 by supply pipe 2.In collating unit 3, the fork 4 of a spin finish fluid in fluid distributing element 5 is arranged, distribution member 5 is connected with each corresponding section 6 respectively and its number equals the number of section 6.The section 6 that annular is provided with all is identical size, and is separated mutually by separating device 7.7 quilts of separating device as far as possible fully schematically indicate the circumference of annular gap, and this annular gap is connected to above-mentioned section without interruption.In practical design, separating device even can end at inside, so that fluid sprays at the edge of the outstanding lip of the last oil ring circumference of oil ring on whole, and fiber can not run into uneven thing anywhere.
Upstream fluid distribution member 5 is used for guaranteeing the uniform shunting of fluid in circular segments 6 of spinning finisher solution, and such element is suitably designed according to flowing of fluid, therefore, has prevented the influence of disturbing factor basically.Because the effect of determining of fluid distributing element 5, the difference on the clearance height or on oil ring be obliquely installed will be just to the influence that is assigned a minimum of single section 6.Because it is a kind of fluid distributing element 5, and be not a kind of on the annular gap pressure reduction or be used for spin finish is distributed in fluidstatic pressure differential on the circumference of ring, for the collating unit of segmentation, the height in gap and foozle can be very big.The selection of carrying out big gap is possible, and this will not only help simplify producing, and helps reducing significantly because in the danger of the irregular operating parking that causes that may occur aspect the uniformity of spinning finisher solution.
Each circular segments 6 is provided the spin finish fluid of roughly the same amount, and upward oil ring can not have the operation dry situation again on any side.If any, only inhomogeneous distribution can occur in segments area, for this reason, significantly, consider that the part of fluid is distributed, section 6 is even as much as possible in design.On the other hand, the spinning finisher solution the ring circumference on distribution will effect be good more along with the increase of each section quantity, therefore, reduced the size of section 6 in the collating unit.Since the fiber by last oil ring easily on the circumference of last oil ring side direction swing several millimeters, for spin finish is coated on the fiber equably, be necessary the number of section 6 is increased to an infinitely-great degree.In practice, the sector number of 6-48 is just much of that.
According to a preferred embodiment of the present invention, fluid distributing element 5 all is the fluid tip of same precision.Advantageously, its geometry is selected like this, promptly, be in operation, the pressure reduction by this precision fluid tip is in the scope of 0.03-0.50bar, because no longer consider the influence of any distribution factor, yet be not too high by the pressure that the measuring pump 1 that is used for spin finish produces this moment.Therefore, under the situation of present embodiment, guaranteed uniform distribution with the method for hydraulic pressure.Particularly advantageous is that this precision fluid tip is a kind of capillary or pore.
According to the further possible improvement of fluid distributing element 5 of the present invention, this element 5 is designed to a kind of volume gauger that cooperatively interacts.In this case, the fluid of spin finish obtains mechanically uniform distribution.Adopting liquid volumeter under situation, advantageously, adopt paired toothed rotor.Particularly advantageously be, adopt gear volume meter or elliptic wheel volume gauger, certainly, what be used for that volume gauger of the present invention must be suitable is little, for example is micro element.Under the situation of gear volume meter or elliptic wheel volume gauger, two profile of tooth rotors keep meshing and being driven by the pressure that flows to liquid mutually always in the chamber, and each changes the displacement corresponding to an accurate metered volume.Under the situation of known measuring element, measurement by fluid is to adopt single volume metering mechanism to carry out, not such to known measuring element, among the present invention, the several volumes meter is combined together, so that obtain a kind of synchronous shift of compulsory, the fluid that comprises same section (this fluid comes from the pond of a spin finish in the inside of collating unit, it is under the micro-pressure and by a subsidiary measuring pump provides fluid) the uniform distribution of fluid of spin finish, such fluid directly is provided to the oil ring section.
Fig. 2 schematically shows an embodiment according to collating unit of the present invention.In this reference number 1-7 and Fig. 1, has an identical meaning.In this case, fluid distributing element 5 is volume gaugers of a kind of profile of tooth, and this meter all comprises a pair of gear in all cases.Be not illustrated by second gear that driven, but all show such gear in all cases, it mechanically combines with other volume gauger by an axle 8.The several volumes meter can be installed on the axle.The annular geometry of collating unit refers to volume gauger and is set on several axles with the installation of polygonal edge, and they are joined together and transmit power by for example angular wheel 9, joint coupling or flexible shaft.Owing to connect, therefore, can guarantee that all volume gaugers are in fact all with identical speed operation by axle.By these axles, all have been compensated because the difference of the turning moment that variation produced of fluid damping damping.
The present invention is more particularly described should be referring to the following examples, and this embodiment is made of the embodiment of hydraulic transmission of the present invention as Fig. 3 with shown in being coated with, and this embodiment is not as the restriction of fundamental of the present invention.
Fig. 3 and Fig. 4 show same collating unit.Fig. 4 is a side view, and it is to analyse and observe from the center of collating unit.Fig. 3 is an A-A horizontal cross.The external diameter of this collating unit 3 can reach 210mm.The feed of spin finish is carried out from measuring pump and annular distributing pipe or arm 4 by service 2.This distributing pipe has the pond groove, and produces the shunting of spinning finisher solution fluid in the inside of collating unit.For a variety of causes of Machine Design (promptly because the center of collating unit is very accurate, this device has a loop configuration usually, air is fed to the quenching rod), therefore in fact shunting is not carried out at central point, as Fig. 1 and 2 is illustrated, but carry out from a ring pipe around virtual center.Distributing pipe 4 is to 18 same capillaries, 5 feed liquid, and this capillary is machined to the hole on this annular central component and has constituted fluid distributing element.Diameter capillaceous can reach 0.7mm and its length can reach 30mm.Each top capillaceous opens to a section 6, and each section 6 is configured to be positioned at the groove of central component tip side and is spaced from each other by middle separator 7, and this separating device can be erect.Just in time around the outwardly open annular gap of extending between the center and upper component of collating unit 3, its edge has formed the outstanding lip on the bottom and the top that are used to apply spin finish, the height 10 in its gap is 0.2mm.In the gap of appropriate appellation, there not be in addition the section of segmentation again, because section 6 is considerably near circumference, and middle separator 7 has been enough to be used in segmenting.
Be that recording by pressure reduction capillaceous is 0.10bar under 0.7 liter/minute the situation in the whole flow rate of spin finish.This annular gap also has the other pressure reduction less than 0.01bar.Therefore, the pressure reduction in the capillary is 10 times of annular gap.Collating unit can tilt one 45 degree extreme angles and a side of higher ring does not have the operation dry situation, this extreme angles can not occur in production practices.Last oil ring by the situation of segmentation under, owing to be equipped with the capillary of fluid shunting, therefore if the height in gap is still unequal and correspondingly, the hydraulic pressure that overcomes the upper side that is in obliquity is not considered with respect to extra pressure reduction capillaceous, and minimum for the influence of the distribution of the supply rate of spin finish being supplied with each segmentation.
According to the present invention, under the situation of center quenching, the tangible benefit of collating unit is, as top mentioned this device insensitive to disturbing factor, the width difference of these factors such as annular gap, situation about being obliquely installed or dirt, and spin finish solution will evenly spray on whole circumference, also increase the maintainability and the homogenization that helps spinning quality of the next procedure of whole center chilling apparatus and spinning machine in addition.Also possible is that each device has only a measuring pump that is used for spin finish.
To emphasize that below the explanation of noting is, under the situation that batch production is produced, have many spinning stations that are arranged side by side with center chilling apparatus of respective number, the above-mentioned spin finish measuring pump that is used for each center chilling apparatus there is no need separately to occur with the form of the pump that independently has individual drive separately, and advantageously, this measuring pump is the part with a plurality of pumps of a common drive unit.
