Definitions

  • the invention relates to a yarn treatment device with a preferably detachable screw connection of divided treatment bodies, which consist of highly wear-resistant, in particular ceramic material, and the use thereof.
  • the treatment of continuous filament yarn has two main tasks.
  • the yarn, made from industrially produced filaments should be given a textile character and also textile properties.
  • the yarn is treated with regard to specific quality characteristics for further processing and / or for the end product. Some yarn qualities have to be produced, which are not necessary for the products made with natural fibers and cannot be achieved.
  • the areas of application are in the industrial processing of textiles e.g. for the construction sector, automobile construction, but also for carpet production and for special textile products in the sports and leisure industry.
  • spun yarn is to be treated with certain preparations for the best possible industrial processing and the processing process for yarns and fabrics is to be optimized. Optimizing here also means maintaining or increasing certain quality criteria and reducing production costs, which includes downtimes along the entire processing route.
  • the nozzle bodies are made of highly wear-resistant material, otherwise their service life would be much too short.
  • the main source of problems for yarn treatment nozzles lies in the preparation.
  • the yarn is provided with protective substances immediately after the spinning process or the production of individual filaments.
  • the protective substances should be an aid for the subsequent processing.
  • the substances used for the preparation result in an oily sliding property, so that the sliding friction of the yarn remains as low as possible all the way through processing, the risk of damage or yarn breakage is reduced, and the abrasion on the sliding surfaces of the transport and processing systems is as small as possible can be kept possible.
  • electrical charges there are a number of other factors that are influenced by the preparation or the preparation, e.g. electrical charges.
  • the invention was based on the object of developing yarn treatment nozzles or yarn treatment bodies which are as insensitive as possible with regard to the preparation and which allow a long service life. It was in particular part of the task to create a nozzle connection for split yarn treatment copers, which allows quick and precise positioning, and can also be used for highly wear-resistant materials such as ceramics and thermal treatments.
  • connection of divided nozzles has at least one dowel pin, which is held at least in a first body part with mechanical clamping means or holding means, and in a second is passed through a fitting hole, for positioning and assembly / disassembly in the axial direction of the dowel pin connection
  • a nozzle with connecting means only remains operationally reliable if the nozzle, pressure, heat, steam or chemical substances can withstand not all practical problems could be solved satisfactorily using the previous glue connections.
  • Glue connections can also only be examined if the practical conditions are already known.
  • the composition of a glue connection cannot be determined with regard to the attack by as yet unknown chemicals that will be used in the future, possibly with additional heat and moisture.
  • the new solution preferably uses a joint alignment, preferably aligned with the yarn path . Surprisingly, it was found with a corresponding pin connection that, compared to the prior art, the entire nozzle body can be built considerably smaller, as it were, in a miniaturized form.
  • the division between two adjacent yarn runs can be selected much smaller than before. In some applications this even has an effect on the godet size. Thanks to the possibility of miniaturization, thanks to the new connection, additional yarn runs can be provided on one and the same machine size and the overall performance of the machine can be increased accordingly.
  • the connection means otherwise used in watch technology as assembly / disassembly aids and the hien-shaped application are unexpected Brings advantages.
  • the force-related cohesion of the parts can be ensured by a classic screw connection.
  • the new solution is particularly advantageous when used as a swirl nozzle and as a thermal treatment body and, as will be shown, as a migration nozzle.
  • the invention allows a number of particularly advantageous configurations.
  • two dowel pins are used according to a particularly preferred solution.
  • essentially identical fitting holes and on the other hand a fitting hole and an elongated hole fitting hole are made.
  • the clamping means or holding means for the dowel pins can be one - 4 -
  • Tension spring or an open tension ring For this purpose, it is proposed to provide a corresponding groove on the dowel pins for one tension ring each such that the tensioning diameter can be reduced during assembly and disassembly of the dowel pins by an external force effect
  • the dowel pins are preferably miniaturized or needle-shaped in diameter.
  • the dowel pin has a positioning function. For the positioning, the dowel pin only has to be dimensioned so strong that it is not damaged during the assembly of the parts, during the yarn processing process there are hardly any forces on the dowel pins.
  • the force connection is preferably made via a screw connection.
  • an insertion cone is attached to the nozzle body in which the dowel pin is held with the clamping means, which conveys into a relief or a bore extension for the clamping means or a clamping ring as a holding shoulder, for long positioning of the dowel pin.
  • the new solution is also ideally suited for periodic cleaning, which is often carried out using ultrasound.
  • the treatment body is designed in a two-part configuration as a nozzle plate and cover plate, the dowel pins being preferably rotatably fixable with the clamping means in the nozzle plate.
  • the cover plate has a blind hole or a through hole with a slightly enlarged diameter at the end of the hole and a fitting hole for the dowel pin in the hole insertion part.
  • the connection particularly preferably consists of two dowel pins which, even in the assembled state, have very little play in the dowel hole in such a way that the dowel pins remain, at least theoretically, still rotatable.
  • the dowel pins slightly protruding on one side of a nozzle body in such a way that the nozzle bodies can be attached to a base plate in a lego-like manner and also in any number.
  • the use of two dowel pins has the great advantage that the connection is determined geometrically precisely or within a narrow tolerance range with regard to the positioning.This applies when using only one dowel pin if the screw connection itself has a dowel shoulder Disadvantages of more than two dowel pins can arise with regard to the problem of expansion and manufacturing accuracy. This means that in the case of extreme thermal loads, two dowel pins are deliberately preferred. If there is no or only a slight thermal load, two or more can be given - 5 -
  • Dowel pins are used.
  • at least one nozzle part, but preferably both nozzle parts, are made of ceramic material and the dowel pins are made of high-strength steel or ceramic.
  • the invention further relates to the use of the yarn treatment device.
  • FIG. 1a shows a yarn treatment body in section in an exploded view and FIG. 1b shows FIG. 1a in the assembled state;
  • FIG. 2a shows a swirl nozzle as section III-III of FIG. 2b;
  • Figure 2b shows a section IV - IV of Figure 2a;
  • 3 shows an arrangement with different dowel pins and holes;

  • FIGs 1 a and 1 b show a two-part air treatment body 1 in section, Figure 1 a in the sense of an exploded view.
  • the treatment body consists of a nozzle plate 3 and a cover plate 2. Both parts can be rigidly connected to the air treatment body 1 with a screw 4 (FIG. 1b).
  • the nozzle plate 3 and the cover plate 2 are secured with two dowel pins 5, 5 'against shifting in one plane (denoted by X-X in FIG. 1b) in accordance with arrow 6.
  • the dowel pins 5, 5 'shown have a double function in the example shown.
  • nozzle plate and cover plate In addition to the positioning of the nozzle plate and cover plate relative to one another, they also serve to fix the entire air treatment nozzle 1 locally on a processing machine (not shown) 7.
  • the dowel pins 5, 5 ' are already installed in one of the nozzle parts by the manufacturer. It is important that glue, sweat is not applied - or - 6 -
  • a tensioning spring or tensioning ring 10 represents the mechanical clamping means.
  • a shoulder grind 1 1 which is approximately similar to the tensioning means is attached in the nozzle plate 3 following an insertion cone 1 2.
  • the insertion cone 1 2 facilitates the automatic assembly of the dowel pins.
  • the nozzle plate 3 has two fitting bores 1 3.
  • the dowel pin 5 can also be inserted into the through hole 1 4 by hand until the clamping ring 10 is at the constriction of the insertion cone.
  • the rest of the movement for the insertion of the dowel pin 5 can be done with a flick e.g. by means of a rubber hammer, so that the tension spring 10 jumps into the hammer joint.
  • the dowel pin 5 protrudes on both sides, as indicated by PD (positioning of nozzle parts) and PM (positioning on the machine).
  • the counterpart to the nozzle plate 3 is the cover plate 2, which has an identical distance A corresponding to two axially parallel fitting bores 1 5 and 1 6.
  • the fitting bore 1 5 can be a normal cylindrical bore with a diameter D, but the second is preferred, as an elongated hole DL with some longitudinal play in the direction of the dimension A for the expansion of the body under the action of heat.
  • both parts 2, 3 takes place for the first time at the manufacturer.
  • user operation e.g. For cleaning the parts after loosening the screw 4, the parts are taken apart in the axial directions of the dowel pins.
  • Another great advantage of the proposed solution is that the later recycling is improved by the easy separability of the parts and each material can be processed separately. This is also important because the yarn treatment nozzles are wearing parts.
  • FIGS. 2a and 2b show a special shape of a yarn channel 20 for the swirling of yarn with compressed air or another medium.
  • the location for a compressed air connection is marked with DL, whereby the compressed air of e.g. 1 to 6 bar is introduced into the yarn channel 20 via a compressed air supply bore 21.
  • the two dowel pins 5, 5 ' are preferably arranged on a common straight line 22 (VE) together with the screw 4. This makes the fitting connection as well as the force connection optimal, and allows a particularly narrow division for the yarn run (as can be seen from FIG. 5b).

  • Fitting hole 1 5 ends with a blind hole 30, which serves to define the fitting hole 1 5 in a defined manner.
  • the dowel pin 5 is flush as a second variant in the area of the impact point with the corresponding nozzle part.
  • a through hole 30 ' is drilled
  • one or the other, or both can be used on the same nozzle. Another great advantage can be seen from the variations shown.
  • the two basic bodies of the yarn treatment nozzles are made of a highly wear-resistant and very expensive material, in particular ceramic.
  • the bores or seats for the clamping means can be produced in a standardized or automated manner with regard to the diameters and diameter ratios.
  • the dowel pins on the other hand, can be manufactured as inexpensive decollage parts in different lengths for the respective application
  • FIG. 4a shows the positioning of a two-part nozzle body 1 or 40, as well as the local fixation on a machine 7.
  • FIG. 4b shows an example of how two yarn treatment bodies 1 and 40 can be mounted in mirror image on a base carrier 7.
  • FIGS. 5a and 5b show a thermal treatment body 40 which has two flow chambers 41, 41a, especially for the treatment of yarn with hot steam or hot air.
  • Each flow chamber has a yarn inlet 42, a yarn outlet 43 and a medium feed opening 44 in the central region. If the medium is superheated steam, the disadvantage of today's extremely high yarn transport speeds, together with the preparation on the yarn, is that the conditions are extremely aggressive.
  • the two continuous chambers or steam chambers have a remarkably large longitudinal dimension KL, which is process-related or must be determined on a case-by-case basis
  • the yarn treatment body 40 has not only one but two pass-through chambers 41 and 41a.
  • the two chambers can be particularly close to one another If many parallel yarn runs are required, this is particularly advantageous because the pitch T between two adjacent yarn runs can be selected to be extremely small.

  • a texturing process is shown from top to bottom and a swirling process correspondingly on the right.
  • WO97 / 30200 Plain yarn 100 is guided from above via a first delivery unit LW1 at high transport speed V1 to a texturing nozzle 101 and through the yarn channel 104.
  • Via compressed air channels 103 which are connected to a compressed air source Pf, highly compressed air is blown into the yarn channel 104 at an angle in the transport direction of the yarn.
  • the yarn channel 104 is opened conically in such a way that a supersonic flow, preferably with more than Mach 2, occurs in the conical section 102.
  • the shock waves generate the actual texturing, as described in detail in WO97 / 30200.
  • the first section from the air injection point 105 into the yarn channel 104 to the first section of the conical extension 102 serves to loosen and open the plain yarn so that the individual filaments are exposed to the supersonic flow.
  • the texturing takes place depending on the level of available air pressure ( 9 1 2 to 14 bar and more) either within the conical part 102 or in the outlet area instead There is a direct proportionality between Mach number and texturing The higher the Mach number, the stronger the impact and the more intense the texturing.

  • two guide webs 1 24 are arranged in a U-shape, which guide the yarn 100 ′ laterally over the preparation lips 1 23.
  • the base body 1 21 preferably has a curved guide groove 1 25 in such a way that the thread run is gently guided over the point of contact of the yarn 100 'with the preparation agent.
  • the preparation agent is applied to the yarn in the manner of an entraining effect. Because the preparation agent in the feed channel 1 22 is only under pressure insofar as safe refilling is ensured, it is not possible to wet all the filaments of the yarn evenly. The result is that the yarn cannot be provided with the preparation agent sufficiently homogeneously over the preparation hops. Depending on the type of preparation, the preparation film, which is partly applied on one side, dries quickly, so that the effectiveness remains reduced. The inventors have now recognized that this problem can be remedied by subjecting the yarn 100 ′ to a more intensive vortex flow at a distance FA shortly after the preparation.
  • a double vortex flow has proven to be optimal, which produces a thorough mixing of the preparation agent in the entire yarn composite and at the same time a crossing of the filaments in the thread.As a rule, intermingling knots should be avoided.
  • the migration nozzle only serves half of the work in terms of vortexing. The yarn is opened by the double vortex flow and the individual filaments are crossed against each other

Abstract

L'invention concerne un assemblage par goujons destiné à maintenir des corps de traitement des fils en une seule, deux ou plusieurs pièces, en particulier des buses de torsadage des fils ou des corps de traitement thermique, en une position exacte pendant toute leur durée de service, même en cas de sollicitations extrêmes de préparation. A la place d'assemblage par brasure ou par collage utilisé jusqu'à présent, on a recours à des moyens de fixation mécaniques pour maintenir les goujons d'assemblage sur une partie de la buse. La fixation des goujons est ainsi assurée sans risque d'être affectée ni par la chaleur, ni par des préparations chimiques. Comme moyen de fixation simple, on utilise un anneau de serrage qui maintient en position le goujon d'assemblage directement dans le corps de la buse, entre une goupille de serrage et une dépouille. Le nouveau moyen de positionnement peut être utilisé sur des éléments individuels de buses, des éléments de buses sur des machines ou de multiples éléments de buses. Les goujons d'assemblage permettent d'obtenir une forte miniaturisation de l'ensemble du corps de la buse, ainsi qu'une répartition étroite entre différents passages de fils, ce qui n'était pas possible jusqu'à présent. L'invention peut être utilisée avantageusement dans des buses de torsadage et des corps de traitement par la vapeur.
