Definitions
- the invention relates to a device for the continuous processing of a thread-like material with several process steps.
- textiles In order for textiles to fulfill their purpose and have the desired properties in terms of feel, appearance and behavior, they are specially processed. In addition to fiber production, yarn and yarn production and surface formation, there are other processes that affect the textile properties.
- finishing processes can be carried out in all process stages, there are finishing processes for fibers, yarns / threads and fabrics. Some finishing processes can be integrated into the manufacturing or finishing process, while others are discontinuous.
- the straight line structure of the single yarns or of the cabled yarns or twines is heat-set, resulting in cut pile carpets with straight, adjacently arranged pile legs.
- Frieze yarns For Frieze yarns, a three-dimensional deformation is transferred to the yarn in a separate process between the cabling process and the heatset process.
- the yarn is deformed three-dimensionally by bending / compression and this state is heat-set.
- the yarns are formed in the finished carpet at Thomaspolwaren like a Kgurstock. These carpets show a lively surface texture that is less sensitive to footprints. More than half of the cabled yarns or threads processed in cut-pile tufted carpet worldwide are given a so-called Frieze look or textured look in a thermomechanical process.
- the cabled yarns or threads are subjected to a subsequent heat setting process.
- the yarn relaxes and can shrink and bag depending on the type of material.
- a maximum bulge is desired, for this the thread must be free of tension, in particular free of tension and pressure, through the heat-setting device.
- the yarn rotation is thereby permanently stabilized or fixed, which leads to a significantly better durability and durability of the carpets or carpets produced therefrom in later use of the yarns.
- the DE 1 635 125 A1 describes a method and an apparatus for treating yarn in which the yarn is subjected to a plurality of treatment operations. For this purpose, a group of threads is continuously guided by successively arranged individual units.
- the compression chamber has next to a channel inlet and a channel outlet a through-channel. With a hinge on the channel wall, a so-called retaining flap is arranged at the channel outlet, which exerts a retaining force counter to the transport direction of the threads to be crushed.
- the threads to be crushed pass through the channel inlet into the through channel and are thereby braked at the walls of the through channel and the retaining flap until the Garnpfropfen is so large that the retaining force of the retaining flap is overcome and the threads over a channel outlet downstream sliding surface on a Conveyor belt to come to rest. Following this, the threads on the conveyor belt are fed to a separate thermofixing device.
- the loop outlet contains a hollow shaft into which a storage tube protrudes. Together with the hollow shaft, the storage tube can be driven irresistibly.
- the threads which are supplied by the pair of delivery rollers, pass through an inlet sleeve in a passageway and finally into the channel of iridescent storage ear, so that the threads are stored in the form of thread loops on a conveyor belt to then go through a separate thermofixing. Neglecting the bending radii one speaks of uncrowned respectively straight set threads.
- each workstation has a steam fixing device which can be operated with saturated steam or superheated steam and serves to fix the yarn withdrawn from the twisting device.
- the inlet and outlet openings have thread locks, which serve to seal the thread treatment chamber to the environment.
- Such sluice gates are important components of such Garn oppositionshuntn, since on the one hand during operation an efficient seal must be ensured by the continuous yarn, on the other hand, the friction of the passing yarn should be as low as possible.
- the passage of the yarn through the device is achieved by a respective upstream of the device and a device downstream of the delivery mechanism.
- the two delivery mechanisms of the respective work station are controlled in such a way that the yarn passing through the device passes essentially without tension.
- the yarn is wound on a spool.
- a disadvantage of the method and the device is that for fixing an effect of this single aggregate another aggregate, which generates, for example, a Frieze effect, must be followed, whereby a relatively large amount of space is needed.
- the EP 0 222 2 14 A2 discloses a method for treating a fiber tow in an apparatus into which the fiber tow is inserted, crimped, gasified, and re-exported.
- the method is particularly suitable for the treatment of fiber tow produced by the dry spinning process, especially for acrylic fiber cable and is particularly low energy and low emissions.
- a disadvantage of this method is that no effects other than crimping can be achieved.
- CH 433 172 A discloses an apparatus for wet-treating and then aftertreating textile fabrics.
- a wet treatment part screen drum, spray device or pad
- a post-treatment part are arranged in pressure-equal spaces in a chamber. After the textile has passed through the padding, it is folded on a band and so driven by the damper. The goods inlet and outlet is sealed by rollers.
- partitions can be provided and, since the temperature in the treatment chamber is usually very high, in cases where the applied liquid may not tolerate this temperature, a cooling of the foulard rolls and / or the fleet.
- a disadvantage of such a device is that only one wet treatment part is present and other effects, such as shaping can not be achieved. Furthermore, in a device according to the CH 433 172 A no different temperature zones are guaranteed.
- the DE 10 2007 014 556 A1 discloses according to title a combination of a method for producing Frieze yarn with a cabling or twisting machine or integration of this method in a cabling and twisting machine connected to a heat-set unit.
- the textile yarn is first subjected to the cabling or twisting process, then the Frieze effect is produced and then the thus formed textile yarn is fixed in the heat-set unit.
- the device for frieze production can be arranged before the heat-set device or integrated into the heat-set device. All three process steps should be combined in one machine.
- a disadvantage of the method is that the proposed solid integration of all units in a machine reduces the flexibility of the process management, since only yarn with Frieze effect can be produced with this cabling or twisting machine. Furthermore, if the Frieze device is integrated into the heat set device, high setting temperatures prevail in the stuffer box of the Frieze unit and the heat set unit. However, if the fixing temperature already acts on the retaining flap of the stuffer box during compression of the thread, stinging causes pressure points of the intersecting thread layers which are also fixed. These pressure points affect the uniformity of the yarn, which, for example, during dyeing and thus in the subsequent fabric leads to a non-uniform appearance of the fabric.
- the object of the present invention is therefore to propose a device which reduces or eliminates the aforementioned disadvantages.
- the aim is to increase flexibility, save energy and improve product quality.
- a delivery device, a treatment and storage device, a transport device, a heat-setting and a length compensation device are arranged in a common closed system, the closed system in its interior differs by a substantially equal pressure from the environment and within the system for the various process steps shielded subsystems are present to the respective supply facilities are connected, which produce at least different temperatures in the subsystems.
- the basic idea of the invention is to be able to carry out the treatment for effecting and thermosetting within a closed system, with all devices for effecting or shaping, for the ordered filing of the thread, for transporting the thread through the temperature zones and for controlled thread storage for length compensation are within system limits and the heat-setting unit is preferably operated with saturated steam, that is, under a high pressure corresponding to the high temperature.
- the completed system includes subsystems, such as a compressed air zone subsystem, a steam zone subsystem, and a cooling zone subsystem.
- subsystems such as a compressed air zone subsystem, a steam zone subsystem, and a cooling zone subsystem.
- thermofixing which, depending on the material, for example for saturated steam as the fixing medium, is usually in the range between 110 ° C. and 150 ° C.
- the subsystem effect generation and thread tray is arranged on a conveyor belt, which operates at system pressure.
- the thread is treated.
- the treatment device may, for example, deform the thread or contain a printer which continuously prints the thread.
- the treatment can also consist of the fact that the thread is passed through a liquor within the treatment device, which gives the thread, for example, hydrophobic, antistatic or fungicidal properties.
- the temperature gradient between the compressed air and steam zones supports the result to be achieved.
- the conveyor transports the stored thread at a defined speed through a shield into the steam zone. There, the heating takes place on the so-called heat setting temperature or temperature and the thread undergoes a material-related shrinkage and Bausch.
- the system pressures result from the material-specific process temperatures for thermofixing.
- these are generally in the range between 110 ° C and 150 ° C.
- the thread is cooled to a target value below the glass transition temperature by means of compressed air so that the state present in the vapor zone is permanently stabilized or fixed and thus becomes resistant to mechanical stresses in subsequent processes and in the finished carpet.
- the subsystem thread storage with deslagger can also be located.
- the limits of the system in which the thread-like material enters or exits formed by locks that suppress pressure equalization with the environment. At the boundaries of the subsystems with each other, only temperature shields are present.
- the housing is pierced only by the thread inlet and outlet, as well as the supply and discharge lines of the required for operation media streams for saturated steam, air and condensate.
- the treatment device is a shaping device.
- the yarn is given a voluminous or deformed appearance after being cabled or twisted.
- the treatment device is a combined device for generating a Frieze- or alternatively a straight set effect.
- a device can be used here with which both frieze yarns, ie with a three-dimensional shape, can be used Straight set yarns, ie in the elongated state, can be produced. To change from one procedure to the other no re-threading or no knotting of the threads has to be made here.
- the Friezevor Vietnamese is designed for example as stuffer box.
- the thread is conveyed by the delivery mechanism into a chamber in which a wall segment is set under load (for example by spring force or compressed air) and closes the space.
- a Fadenpfropfen forms against the force-loaded retaining flap, which as soon as the plug pressure exceeds the counterforce of the retaining flap leaves the compression chamber again.
- the height of the retaining flap resistance thereby determines the intensity of the three-dimensional deformation formed in the plug, i. the intensity of the frieze character.
- the influence of the intensity of the frieze character is achieved by changing the retention flap force.
- the deformed Frieze yarn is deposited in a controlled manner by means of a funnel-shaped element, for example a pipe elbow, whose outlet opening is fixed and points in the direction of the transport device.
- a funnel-shaped element for example a pipe elbow
- the formed Frieze yarn slides down under its own weight and as a result of the continuous supply in the interior of the elbow and lies down on the moving conveyor belt.
- the retaining flap In the case of change to the production of straight set yarn, the retaining flap is placed in the rear position by means of a suitable control and remains there for the entire production time. In this way creates a barrier-free chamber through which the thread runs distraction-free.
- the funnel-shaped element is driven in rotation by means of a drive, for example a stepping motor.
- the thread is thus thrown out of the delivery unit on the resulting centrifugal force to the outside and runs stretched within the stuffer box.
- the thread lays on the transport device ordered in a circular arc form.
- the Ablegeradius which is influenced by the amount of centrifugal force, the weight of the thread and the conveyor belt speed, it is so large set that the circularity still as quasi straight (Straight) in the yarn knots of the finished carpet represents.
- the treatment device is a dyeing device.
- the thread is to be dyed continuously, then a corresponding device known per se can be arranged in the closed system. After the thread has been pulled through a dyeing liquor and squeezing rollers, it is deposited on the conveyor belt.
- the stretching is produced by means of a length compensation device, for example a loop store with a loading weight, whereby a thread tension is created between the starting delivery station and a binding point on the conveyor belt.
- the setting point on the conveyor belt can be defined with a freely rotatably mounted roller with a defined line load, consisting of the roll weight plus optionally a spring. This roller forms a bond to the conveyor belt piece located in front of it, so that only the respective piece of thread that is just passing through the pressure line is stretched by the weight in the loop store.
- a circular-arched tray in the case of straight-yarn production, a whole arc is always released.
- Frieze yarns the three-dimensional bow is stretched out.
- the yarn storage is designed for both cases to the maximum released thread length.
- weight memory thus takes place a permanent up-and-down movement, in the case of straight yarn production by the respective liberated length of a whole storage sheet.
- the position of the load weight is scanned by means of suitable sensors, preferably non-contact sensors (for example Hall sensors or optical sensors).
- sensors can be used, which continuously record the exact position over the entire possible travel.
- a possible simple variant is a two-position recognition, whereby a suitable software can let the output supply work a little faster when the lower sensor is reached and, when the upper sensor is reached, can drive the output supply unit more slowly.
- Claim 8 states that individual subsystems form a structural unit and can be removed from the closed system.
- the subsystems allow the entire system to be configured as a modular system. Individual subsystems such as the treatment device can thus be replaced or removed for maintenance purposes from the overall system.
- multiple subsystems are mounted together on a holder, such as a carriage.
- This slide is as a whole in a compressed air, which largely corresponds to the system pressure, standing housing.
- this solution is because the entire unit for maintenance and cleaning as a drawer can be pulled forward.
- the utilities are connected to a central supply.
- System parameters can be set particularly preferably according to claim 10.
- Either the system parameters, such as the delivery speeds, the conveyor belt speed, the rotation speed of the storage pipe, the air pressures and the temperatures can be entered at the central control unit or locally at the respective workstation computers.
- the system parameters also include the selection of whether a frieze or straight effect is to be achieved and to what extent the Frieze effect is formed. In this way, it is possible to set the system to material-specific features and so can process a wide variety of materials.
- system parameters can be specified either for the entire machine, for individual machine pages, for sections or individually for each workstation.
- an automatic threading for example by means of compressed air, is provided.
- the device can be integrated into the yarn path of Fadenher einsrataen- or yarn processing processes or operated independently. Particularly suitable is the device for the finishing of carpet yarns. Therefore, in particular the device according to the invention can be integrated into the yarn path of cabling or twisting machines. It would also be conceivable, however, an arrangement, for example, before a tufting machine, downstream in a spinning machine or an extruder or another filament-type good processing textile machine.
- the device can be used for monofilaments, but it is also possible that a group of threads in the system to achieve an effect and its fixation is performed.
- FIG. 1 shows schematically and greatly simplified as the inventive method in a Fadenher eins- respectively thread processing process 2, here the cabling or twisting process, can be integrated.
- the thread 1 is transferred through an entrance lock 4 into the system 5.
- the yarn 1 returns to the atmosphere through an exit lock 6 and is then wound in the winding device 7 onto the package 9 held by a creel 8.
- FIG. 2 shows schematically the device according to the invention.
- the system 5 is limited by a housing 38.
- a first subsystem is the compressed air zone 31, which is under system pressure, as required, with elevated temperature as the preheating zone and optionally also a compressed air / vapor mixture.
- a combined Frieze / Straight Set device 35 Integrated as a further subsystem is a combined Frieze / Straight Set device 35, which also operates fully in system pressure.
- the thread 1 is pulled via a delivery mechanism 10 through the entrance lock 4 into the system 5.
- the thread 1 is continuously conveyed into a stuffer box 11 and at the exit against a spring-loaded retaining flap 12, which closes the output of the stuffer box 11, pressed. Due to the mechanical dynamic pressure in the stuffer box 11, the thread 1 is bent and / or kinked (crimped) in a geometrically irregular manner in three dimensions.
- the in the stuffer box 11, also called stuffer box, crinkled thread group forms against the kraftbeaufschte retaining flap 12 from a Fadenpfropfen, as soon as the plug pressure, the counterforce the retaining flap 12 exceeds the compression chamber leaves again.
- the height of the retaining flap resistance thereby determines the intensity of the three-dimensional deformation formed in the plug, ie the intensity of the frieze character.
- the next subsystem 36 ensures controlled deposition onto a conveyor (e.g., a conveyor). From the compression chamber 11 of the thread 1 passes through a storage tube 13, the outlet opening is fixed and facing in the direction of the conveyor belt 14. The formed Friezegarn slips down under its own weight and due to the continuous supply in the interior of the storage tube and lies down on the conveyor belt 14th
- the deposited thread 1 passes through a separation point 39 on the conveyor belt 14 at a defined speed and enters the steam zone 32. There, the heating takes place on the so-called heat setting temperature or temperature, in practice usually by means of saturated steam or superheated Steam.
- the thread undergoes a material-related shrinkage and bulge.
- corresponding mechanical separating elements 39 here a slit diaphragm, are provided.
- the upstream compressed air zone 31 or downstream cooling zone 33 is acted upon by compressed air and a pressure corresponding essentially to the vapor pressure. Both ensure a low media exchange between the individual zones.
- the thread 1 is cooled by compressed air to below the material-specific glass transition temperature, so that the present in the vapor zone 32 state is permanently stabilized or fixed and thus against mechanical stress in subsequent processes, such as winding, tufting or weaving and becomes resistant in the finished carpet.
- the thread 1 Since the thread 1 should then leave the system 5 for further processing and winding stretched on a spool, the thread 1 must be brought back into the stretched state.
- the stretch is generated via a loop memory 20 with a load weight 42, whereby a yarn tension between diarytician 24 and a Abbindeddling on the conveyor belt 14 is generated.
- the thread or loop memory 20 is a permanent up-and-down movement, in the case of straight set yarn production by each released length of a whole storage sheet.
- the position of the loading weight 42 is scanned by means of suitable Hall sensors 21, 22.
- the trigger delivery 24 is controlled, the controller 44 when reaching the lower sensor 21, the trigger delivery 24 run a little faster and on reaching the upper sensor 22, the trigger delivery 24 drives more slowly.
- the system 5 is supplied via the compressed air inlet 25, the saturated steam inlet 26 and the compressed air inlet for the cooling zone 27. Together with the outlet for air 28, the outlet for steam / condensate 29 and the outlet for air from the cooling zone 30, a continuous supply and disposal of the system 5 is ensured.
- the storage tube 13 has a drive (not shown), for example a stepping motor.
- a drive for example a stepping motor.
- the retaining flap 12 which is attached to the wall of the stuffer box 11 with a hinge, is placed in the rear position and remains there for the entire production time.
- the stuffer box 11 has become in this way a guide without hindrance to the continuous thread 1.
- the storage tube 13 is rotationally driven.
- the thread 1 is thus thrown out of the delivery mechanism 10 on the resulting centrifugal force to the outside and runs within the stuffer box 11 stretched.
- the thread 1 lays on the conveyor belt 14 ordered in a circular arc form.
- the Ablegeradius which is influenced by the amount of centrifugal force, the weight of the thread 1 and the conveyor belt speed, it is set so large that the circular arc still represents as quasi straight in the yarn nubs of the finished carpet.
- the setting point on the conveyor belt 14 is defined with a freely rotatably mounted setting roller 17 with a defined line load.
- This Abbindewalze 17 forms a bond to the transport belt piece 14 located in front of it, so that only the respective piece of thread that just passes through the printing line, is stretched by the weight 42 in the loop memory 20.
- a whole arc is always released.
- the Frieze yarns the three-dimensional bow is stretched out.
- the thread store 20 is designed for both cases to the maximum liberated thread length.
- FIG. 4 shows the device according to the invention with several subsystems, while the subsystem compressed air zone 31, the subsystem steam zone 32 and the subsystem cooling zone 33, which are assembled on a carriage 43, the yarn store 20 is also included in the housing.
- the carriage 43 is located as a whole in a pressurized housing 38.

Description
Die Erfindung betrifft eine Vorrichtung zur kontinuierlichen Bearbeitung eines fadenförmigen Gutes mit mehreren Verfahrensschritten.The invention relates to a device for the continuous processing of a thread-like material with several process steps.
Damit Textilien ihren Verwendungszweck erfüllen und in Griff, Aussehen und Gebrauchsverhalten die gewünschten Eigenschaften aufweisen, werden sie speziell bearbeitet. Neben der Fasergewinnung, Garn- und Zwirnerzeugung sowie der Flächenbildung gibt es weitere Verfahren, die die textilen Eigenschaften beeinflussen.In order for textiles to fulfill their purpose and have the desired properties in terms of feel, appearance and behavior, they are specially processed. In addition to fiber production, yarn and yarn production and surface formation, there are other processes that affect the textile properties.
Je nach Verwendungszweck wird zum Beispiel eine größere Stabilität oder mehr Volumen im fadenförmigen Gut, eine Erhöhung der Temperaturbeständigkeit, eine Färbung, eine wasserabweisende oder fungizide Ausrüstung erforderlich, um nur einige Beispiele zu nennen.Depending on the application, for example, greater stability or more volume in the filamentary material, an increase in temperature resistance, a coloring, a water-repellent or fungicidal equipment is required, to name but a few examples.
Diese so genannten Veredlungs-Verfahren können in allen Prozessstufen durchgeführt werden, es gibt Veredlungsverfahren für Fasern, Garne/Zwirne und Flächengebilde. Einige Veredlungsverfahren lassen sich in den Herstellungs- oder Weiterverarbeitungsprozess integrieren, andere wiederum sind diskontinuierlich.These so-called finishing processes can be carried out in all process stages, there are finishing processes for fibers, yarns / threads and fabrics. Some finishing processes can be integrated into the manufacturing or finishing process, while others are discontinuous.
Viele dieser Veredlungs-Verfahren benötigen eine anschließende thermische Fixierung, die üblicherweise in Dampfatmosphäre oder unter trockener Hitze durchgeführt wird, um die wünschenswerten Eigenschaften dauerhaft zu stabilisieren. Üblicherweise wird der Fixierungsprozess in der Textilindustrie als Thermofixierung bezeichnet, im Bereich der Teppichgarnherstellung wird das Synonym Heatsetprozess verwendet.Many of these finishing processes require subsequent thermal fixation, which is usually carried out in a steam atmosphere or under dry heat to permanently stabilize the desirable properties. Usually, the fixation process in the textile industry is referred to as heat setting, in the field of carpet yarn production, the synonym heatset process is used.
Im Bereich der Teppichgarnherstellung beispielsweise gibt es so genannte Straight Set-Garne und Frieze-Garne.In the field of carpet yarn production, for example, there are so-called straight set yarns and Frieze yarns.
Beim Straight Set-Garn wird die gerade linienförmige Struktur der Einfachgarne oder der kablierten Garne bzw. Zwirne thermofixiert, was in Schnittpolteppichen zu geraden, nebeneinander geordneten Polschenkeln führt.In the case of the straight set yarn, the straight line structure of the single yarns or of the cabled yarns or twines is heat-set, resulting in cut pile carpets with straight, adjacently arranged pile legs.
Für Frieze-Garne wird zwischen dem Kablierprozess und dem Heatsetprozess dem Garn in einem separaten Prozess eine dreidimensionale Verformung überprägt. Dabei wird das Garn durch Biegung/Stauchung dreidimensional verformt und dieser Zustand thermofixiert. Die Garne sind im fertigen Teppichboden bei Schnittpolwaren wie ein Krückstock geformt. Diese Teppiche zeigen eine lebhafte Oberflächenstruktur, die unempfindlicher gegenüber Trittspuren ist. Mehr als der Hälfte der weltweit in Schnittflor-Tuftingteppichen verarbeiteten kablierten Garne bzw. Zwirne wird in einem thermomechanischen Prozess eine so genannte Frieze-Optik bzw. Textured-Optik erteilt.For Frieze yarns, a three-dimensional deformation is transferred to the yarn in a separate process between the cabling process and the heatset process. The yarn is deformed three-dimensionally by bending / compression and this state is heat-set. The yarns are formed in the finished carpet at Schnittpolwaren like a Krückstock. These carpets show a lively surface texture that is less sensitive to footprints. More than half of the cabled yarns or threads processed in cut-pile tufted carpet worldwide are given a so-called Frieze look or textured look in a thermomechanical process.
Nach der Verformung werden die kablierten Garne oder Zwirne einem anschließenden Thermofixierprozess unterzogen. Durch das aufeinanderfolgende Heizen und Kühlen relaxiert das Garn und kann je nach Materialart schrumpfen und bauschen. Gewünscht ist in der Regel ein maximaler Bausch, dazu muss der Faden spannungsfrei, insbesondere zug- und druckspannungsfrei, durch die Thermofixiereinrichtung laufen. Weiterhin wird dadurch die Garndrehung permanent stabilisiert bzw. fixiert, was im späteren Einsatz der Garne zu einer wesentlich besseren Strapazierfähigkeit und Haltbarkeit der daraus hergestellten Teppiche bzw. Teppichböden führt.After deformation, the cabled yarns or threads are subjected to a subsequent heat setting process. By successive heating and cooling, the yarn relaxes and can shrink and bag depending on the type of material. As a rule, a maximum bulge is desired, for this the thread must be free of tension, in particular free of tension and pressure, through the heat-setting device. Furthermore, the yarn rotation is thereby permanently stabilized or fixed, which leads to a significantly better durability and durability of the carpets or carpets produced therefrom in later use of the yarns.
In der Praxis ist es so, dass diese Verfahren durch voneinander unabhängige Einzelaggregate durchgeführt werden.In practice, these processes are carried out by independent individual units.

Sollen hingegen ungekräuselte Fäden respektive Straight Set-Garne oder Zwirne hergestellt werden, so ist dazu ein so genannter Schlaufenableger notwendig. Der Schlaufenableger enthält eine Hohlwelle, in die ein Ablagerohr hineinragt. Zusammen mit der Hohlwelle ist das Ablagerohr changierend antreibbar. Die Fäden, die durch das Lieferwalzenpaar zugeführt werden, gelangen durch eine Einlaufhülse in einen Durchgangskanal und schließlich in den Kanal des changierenden Ablagerohres, so dass die Fäden in Form von Fadenschlaufen auf einem Transportband abgelegt werden, um danach eine separate Thermofixiereinrichtung zu durchlaufen. Unter Vernachlässigung der Biegeradien spricht man von ungekräuselten respektive Straight Set-Fäden.

Die Einlauf- und Auslauföffnungen weisen Fadenschleusen auf, die der Abdichtung der Fadenbehandlungskammer zur Umgebung hin dienen. Solche Fadenschleusen sind wichtige Bestandteile derartiger Garnbehandlungskammern, da einerseits während des Betriebes eine effiziente Abdichtung durch das durchlaufende Garn gewährleistet sein muss, anderseits die Reibung des durchlaufenden Garns möglichst gering sein sollte. Die Hindurchführung des Garns durch die Vorrichtung wird durch jeweils ein der Vorrichtung vorangestelltes und ein der Vorrichtung nachgeordnetes Lieferwerk erreicht. Hierzu werden die beiden Lieferwerke der jeweiligen Arbeitsstelle derart angesteuert, dass das die Vorrichtung durchlaufende Garn im Wesentlichen spannungslos durchläuft. Unmittelbar nach dem Verlassen der Behandlungsvorrichtung wird das Garn auf eine Spule aufgewickelt.The inlet and outlet openings have thread locks, which serve to seal the thread treatment chamber to the environment. Such sluice gates are important components of such Garnbehandlungskammern, since on the one hand during operation an efficient seal must be ensured by the continuous yarn, on the other hand, the friction of the passing yarn should be as low as possible. The passage of the yarn through the device is achieved by a respective upstream of the device and a device downstream of the delivery mechanism. For this purpose, the two delivery mechanisms of the respective work station are controlled in such a way that the yarn passing through the device passes essentially without tension. Immediately after leaving the treatment device, the yarn is wound on a spool.
Nachteilig an dem Verfahren und der Vorrichtung ist allerdings, dass zur Fixierung eines Effektes dieses Einzelaggregat einem anderen Aggregat, das beispielsweise einen Frieze-Effekt erzeugt, nachgeschaltet werden muss, wodurch relativ viel Bauraum benötigt wird.A disadvantage of the method and the device, however, is that for fixing an effect of this single aggregate another aggregate, which generates, for example, a Frieze effect, must be followed, whereby a relatively large amount of space is needed.

Nachteilig an dem Verfahren ist, dass die vorgeschlagene feste Integration aller Aggregate in einer Maschine die Flexibilität der Prozessführung reduziert, da mit dieser Kablier- oder Zwirnmaschine ausschließlich Garn mit Frieze-Effekt hergestellt werden kann. Des Weiteren herrschen, falls die Frieze-Einrichtung in die Heat-Set-Einrichtung integriert ist, in der Stauchkammer der Frieze-Einheit und der Heat-Set-Einheit hohe Fixiertemperaturen. Wenn aber bereits beim Komprimieren des Fadens auf der Rückhalteklappe der Stauchkammer die Fixiertemperatur einwirkt, entstehen durch die Stauchung bedingte Druckstellen der sich kreuzenden Fadenlagen, die mit fixiert werden. Diese Druckstellen beeinträchtigen die Garngleichmäßigkeit, was beispielsweise beim Färben und damit im späteren Flächengebilde zu einem uneinheitlichen Warenbild führt.A disadvantage of the method is that the proposed solid integration of all units in a machine reduces the flexibility of the process management, since only yarn with Frieze effect can be produced with this cabling or twisting machine. Furthermore, if the Frieze device is integrated into the heat set device, high setting temperatures prevail in the stuffer box of the Frieze unit and the heat set unit. However, if the fixing temperature already acts on the retaining flap of the stuffer box during compression of the thread, stinging causes pressure points of the intersecting thread layers which are also fixed. These pressure points affect the uniformity of the yarn, which, for example, during dyeing and thus in the subsequent fabric leads to a non-uniform appearance of the fabric.
Des Weiteren kann auf diese Weise nur ein eingeschränkter Bausch des Garnes entstehen, der zur Volumenerhöhung notwendig ist.Furthermore, in this way only a limited bulk of the yarn can arise, which is necessary for increasing the volume.
Die Aufgabe der vorliegenden Erfindung ist es demnach, eine Vorrichtung vorzuschlagen, die die zuvor genannten Nachteile reduziert respektive beseitigt. Dabei soll die Flexibilität erhöht, Energie eingespart und die Produktqualität verbessert werden.The object of the present invention is therefore to propose a device which reduces or eliminates the aforementioned disadvantages. The aim is to increase flexibility, save energy and improve product quality.
Diese Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst.This object is achieved by the characterizing features of
Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Advantageous embodiments of the invention are the subject of the dependent claims.
Zur Lösung der Aufgabe wird gemäß Anspruch 1 eine Liefereinrichtung, eine Behandlungs- und Ablagevorrichtung, eine Transportvorrichtung, eine Thermofixiereinrichtung sowie eine Längenausgleichseinrichtung in einem gemeinsamen abgeschlossenen System angeordnet sind, das abgeschlossene System in seinem Inneren sich durch einen im Wesentlichen gleichen Druck von der Umgebung unterscheidet und innerhalb des Systems für die verschiedenen Verfahrensschritte gegeneinander abgeschirmte Untersysteme vorhanden sind, an die jeweils Versorgungseinrichtungen angeschlossen sind, diezumindest unterschiedliche Temperaturen in den Untersystemen erzeugen.To achieve the object according to
Grundgedanke der Erfindung ist, die Behandlung zur Effekterteilung sowie die Thermofixierung innerhalb eines abgeschlossenen Systems durchführen zu können, wobei sich alle Einrichtungen zur Effekt- bzw. Formgebung, zur geordneten Ablage des Fadens, zum Transport des Fadens durch die Temperaturzonen sowie zur geregelten Fadenspeicherung zum Längenausgleich innerhalb von Systemgrenzen befinden und die Thermofixiereinheit bevorzugt mit Sattdampf, das heißt unter einem der Temperatur entsprechenden hohen Druck, betrieben wird.The basic idea of the invention is to be able to carry out the treatment for effecting and thermosetting within a closed system, with all devices for effecting or shaping, for the ordered filing of the thread, for transporting the thread through the temperature zones and for controlled thread storage for length compensation are within system limits and the heat-setting unit is preferably operated with saturated steam, that is, under a high pressure corresponding to the high temperature.
Das abgeschlossene System weist dabei Untersysteme auf, wie zum Beispiel ein Untersystem Druckluftzone, ein Untersystem Dampfzone sowie ein Untersystem Kühlzone.The completed system includes subsystems, such as a compressed air zone subsystem, a steam zone subsystem, and a cooling zone subsystem.
Übliche Systemdrücke ergeben sich aus der materialtypischen Verfahrenstemperatur für das Thermofixieren, die je nach Material, beispielsweise für Sattdampf als Fixiermedium, üblicherweise im Bereich zwischen 110°C und 150°C liegen.Conventional system pressures result from the material-typical process temperature for thermofixing, which, depending on the material, for example for saturated steam as the fixing medium, is usually in the range between 110 ° C. and 150 ° C.
In dem Untersystem Druckluftzone, das je nach Erfordernis mit erhöhter Temperatur als Vorheizzone oder gegebenenfalls auch mit einem Druckluft/Dampfgemisch eingestellt werden kann, ist das Untersystem Effekterzeugung und Fadenablage auf einem Transportband angeordnet, das im Systemdruck arbeitet.In the subsystem compressed air zone, which can be adjusted as required with elevated temperature as preheating zone or possibly also with a compressed air / steam mixture, the subsystem effect generation and thread tray is arranged on a conveyor belt, which operates at system pressure.
Um bestimmte Effekte zu erzielen, wird der Faden behandelt. Dabei gibt es je nach Anforderungsprofil eine Vielzahl von wünschenswerten Eigenschaften, die auf den Faden aufgebracht werden können. Die Behandlungsvorrichtung kann beispielsweise den Faden verformen oder einen Drucker enthalten, der den Faden kontinuierlich bedruckt. Die Behandlung kann aber auch daraus bestehen, dass der Faden innerhalb der Behandlungsvorrichtung durch eine Flotte geleitet wird, die dem Faden zum Beispiel hydrophobe, antistatische oder fungizide Eigenschaften verleiht.To achieve certain effects, the thread is treated. Depending on the requirement profile, there are a large number of desirable properties that can be applied to the thread. The treatment device may, for example, deform the thread or contain a printer which continuously prints the thread. However, the treatment can also consist of the fact that the thread is passed through a liquor within the treatment device, which gives the thread, for example, hydrophobic, antistatic or fungicidal properties.
Um bei der Herstellung von beispielsweise Frieze-Garn Druckstellen zu vermeiden, ist es wichtig, dass sowohl in der Stauchkammer als auch bei der Fadenablage auf dem Transportband eine niedrigere Temperatur vorherrscht als in der anschließenden Dampfzone. Beim Komprimieren des Fadenpfropfens auf der Rückhalteklappe würden andernfalls Druckstellen an den Kreuzungsbereichen des Fadens entstehen, die nicht mehr ausgeglichen werden können und sich zum Beispiel in einem unterschiedlichen Färbeverhalten äußern.In order to avoid pressure points in the production of, for example, Frieze yarn, it is important that a lower temperature prevails on the conveyor belt both in the stuffer box and in the thread restraint than in the subsequent steam zone. When compressing the thread graft on the retaining flap would otherwise create pressure points at the crossing regions of the thread, which can not be compensated and express themselves, for example, in a different coloring behavior.
Auch bei der Herstellung von Straight-Garnen unterstützt das Temperaturgefälle zwischen der Druckluft- und Dampfzone das zu erzielende Ergebnis.Also in the production of straight yarns, the temperature gradient between the compressed air and steam zones supports the result to be achieved.
Das Transportband transportiert den abgelegten Faden mit definierter Geschwindigkeit durch eine Abschirmung in die Dampfzone. Dort erfolgt die Erwärmung auf die so genannte Thermofixiertemperatur oder Bauschtemperatur und der Faden erfährt einen materialbedingten Schrumpf und Bausch.The conveyor transports the stored thread at a defined speed through a shield into the steam zone. There, the heating takes place on the so-called heat setting temperature or temperature and the thread undergoes a material-related shrinkage and Bausch.
Wie bereits erwähnt, ergeben sich die Systemdrücke aus den materialspezifischen Verfahrenstemperaturen für das Thermofixieren. Wird beispielsweise Sattdampf als Fixiermedium verwendet, liegen diese in der Regel im Bereich zwischen 110°C und 150°C.As already mentioned, the system pressures result from the material-specific process temperatures for thermofixing. For example, if saturated steam is used as fixing medium, these are generally in the range between 110 ° C and 150 ° C.
Im folgenden Untersystem Kühlzone wird der Faden mit einem Zielwert unterhalb der Glasumwandlungstemperatur mittels Druckluft gekühlt, damit der in der Dampfzone vorliegende Zustand permanent stabilisiert bzw. fixiert wird und somit gegen mechanische Belastungen in Folgeprozessen und im fertigen Teppich widerstandsfähig wird. In der Kühlzone kann sich zusätzlich das Untersystem Fadenspeicher mit Entschlaufer befinden.In the following cooling zone subsystem, the thread is cooled to a target value below the glass transition temperature by means of compressed air so that the state present in the vapor zone is permanently stabilized or fixed and thus becomes resistant to mechanical stresses in subsequent processes and in the finished carpet. In the cooling zone, the subsystem thread storage with deslagger can also be located.
Da eine Abschirmung zwischen unterschiedlichen Temperaturzonen wesentlich unproblematischer und konstruktiv einfacher zu erreichen ist als die Abgrenzung unterschiedlicher Druckzonen, reicht es aus, zur Stabilisierung der Dampfzone entsprechende mechanische Trennelemente zu verwenden, im einfachsten Fall eine Schlitzblende oder ein fester länglicher Spalt sowie die Beaufschlagung der vorgeschalteten bzw. nachgeschalteten Zone mit Druckluft und einem im Wesentlichen dem Dampfdruck entsprechendem Druck. Beides sichert einen geringen Medienaustausch zwischen den einzelnen Zonen.Since a shield between different temperature zones is much easier and structurally easier to achieve than the delimitation of different pressure zones, it is sufficient to use for stabilizing the steam zone corresponding mechanical separation elements, in the simplest case a slit or a fixed elongated gap and the pressurization of the upstream or downstream zone with compressed air and a substantially corresponding to the vapor pressure. Both ensure a low media exchange between the individual zones.
Das bedeutet, dass die Thermofixierzone nun nicht mehr am Einlauf und am Auslauf des Transportbandes gegen Druckunterschiede abgedichtet werden muss, da beide -Transportband und Thermofixierzone - Bestandteil des geschlossenen Systems sind. Auf die derzeitig in der Praxis übliche Verwendung von Quetschwalzen kann somit verzichtet werden. Damit werden die Nachteile von Quetschwalzen, wie zum Beispiel Druckstellen an Überkreuzungsstellen von mehreren Fadenlagen und daraus resultierende Anfärbeunterschiede vermieden, insbesondere wenn die Quetschwalzen mit noch nicht vollständig abgekühlten Fäden in Kontakt kommen.This means that the heat-setting zone no longer has to be sealed against pressure differences at the infeed and at the outlet of the conveyor belt, since both conveyor belt and heat-setting zone are part of the closed system. On the current practice in practice of squeezing rollers can thus be dispensed with. Thus, the disadvantages of squeezing rollers, such as pressure points at crossover points of multiple layers of thread and resulting staining differences are avoided, especially when the squeezing come with not yet completely cooled threads in contact.
Darüber hinaus sind hier grundsätzlich aber alle bekannten Mittel zur Abschirmung denkbar, wie zum Beispiel Walze gegen Walze oder Walze gegen Band.In addition, however, all known means for shielding are conceivable here, in principle, such as roller against roller or roller against belt.
Die unterschiedlichen Verfahrensschritte werden in einem abgeschlossenen System durchgeführt, das gegenüber der Atmosphäre einen höheren Druck aufweist. Da das System einen weitestgehend gleichen Druck aufweist, muss nur das Außengehäuse in seiner Stabilität die Druckdifferenz von Umgebungsatmosphäre zu Systeminnendruck übernehmen. Auf die Wandung der Dampfzone wirkt nahezu keine Druckdifferenz, was bei der konstruktiven Ausführung für die Dampfzone wesentlich geringere Wandstärken ermöglicht.The different process steps are carried out in a closed system, which has a higher pressure compared to the atmosphere. Since the system has a largely the same pressure, only the outer housing must take in its stability, the pressure difference from the ambient atmosphere to system internal pressure. On the wall of the steam zone affects almost no pressure difference, which allows for the structural design for the steam zone significantly lower wall thicknesses.
Unter fadenförmigem Gut sollen im Rahmen dieser Anmeldung alle linienförmigen Gebilde verstanden werden. Dies können Garne, Zwirne aber auch Folienbändchen sowie schlauch- und bändchenförmige Textilien und dergleichen sein. Zur Vereinfachung wird der Begriff des Fadens gleichbedeutend für die möglichen Alternativen im Rahmen dieser Anmeldung verwendet.Under filamentous good should be understood in the context of this application, all linear structures. This can be yarns, threads but also foil tapes and tubular and ribbon-shaped textiles and the like. For the sake of simplicity, the term thread is used synonymously with the possible alternatives in the context of this application.
Des Weiteren, wie in Anspruch 2 dargelegt, sind die Grenzen des Systems, an denen das fadenförmige Gut ein- oder austritt, durch Schleusen gebildet, die einen Druckausgleich mit der Umgebung unterdrücken. An den Grenzen der Untersysteme untereinander sind nur Temperaturabschirmungen vorhanden.Furthermore, as set forth in claim 2, the limits of the system in which the thread-like material enters or exits, formed by locks that suppress pressure equalization with the environment. At the boundaries of the subsystems with each other, only temperature shields are present.
Die Abdichtung des gesamten Druckraumes zur Umgebung erfolgt am Fadeneingang und Fadenausgang durch Schleusen, im einfachsten Fall gerade Röhrchen, die auf den jeweiligen Durchmesser des Fadens im Hinblick auf minimale Leckage und störungsfreien Garndurchlauf abgestimmt sind. Statt der Garnschleusen können auch andere, bekannte Trennmittel wie beispielsweise Abquetschwalzen zur Abdichtung verwendet werden.The sealing of the entire pressure chamber to the environment takes place at the yarn inlet and yarn outlet through locks, in the simplest case straight tubes, which are tuned to the respective diameter of the thread with regard to minimum leakage and trouble-free Garndurchlauf. Instead of the yarn locks, other known release agents such as squeeze rollers can be used for sealing.
Innerhalb des Systems befinden sich ein weitestgehend gleicher Druck und unterschiedliche Temperaturzonen.Within the system there is a largely equal pressure and different temperature zones.
Das Gehäuse wird nur durch den Fadeneinlass und -auslass durchbrochen sowie die Zu- bzw. Ableitungen der zum Betrieb erforderlichen Medienströme für Sattdampf, Luft und Kondensat.The housing is pierced only by the thread inlet and outlet, as well as the supply and discharge lines of the required for operation media streams for saturated steam, air and condensate.
In einer bevorzugten Ausführungsform gemäß Anspruch 3 ist die Behandlungsvorrichtung eine Formgebungseinrichtung.In a preferred embodiment according to claim 3, the treatment device is a shaping device.
Besonders im Bereich der Teppichgarnherstellung wird nach dem Kablieren oder Zwirnen dem Garn ein voluminöseres oder verformtes Erscheinungsbild verliehen.Especially in the field of carpet yarn production, the yarn is given a voluminous or deformed appearance after being cabled or twisted.
Nach Anspruch 4 ist die Behandlungsvorrichtung eine kombinierte Vorrichtung zur Erzeugung eines Frieze- oder alternativ eines Straight Set-Effekts.According to
Damit bei einem Wechsel von Straight Set-Garnen zu Frieze-Garnen oder umgekehrt nicht immer die entsprechende Behandlungsvorrichtung ausgebaut, getauscht und wieder eingebaut werden muss, kann hier eine Vorrichtung verwendet werden, mit der sowohl Frieze-Garne, d.h. mit einer dreidimensionalen Formgebung, als auch Straight-Set-Garne, d.h. im langgestreckten Zustand, hergestellt werden können. Zum Wechsel von einem Verfahren auf das andere muss hier keine Neueinfädelung bzw. kein Anknoten der Fäden vorgenommen werden.So that when changing from straight set yarns to frieze yarns or vice versa, the corresponding treatment device does not always have to be dismantled, replaced and reinstalled, a device can be used here with which both frieze yarns, ie with a three-dimensional shape, can be used Straight set yarns, ie in the elongated state, can be produced. To change from one procedure to the other no re-threading or no knotting of the threads has to be made here.
Wie bereits beschrieben, ist die Friezevorrichtung beispielsweise als Stauchkammer ausgeführt. In diesem Fall wird der Faden durch das Lieferwerk in eine Kammer gefördert, bei der ein Wandsegment unter Belastung (z.B. durch Federkraft oder Druckluft) angestellt ist und den Raum abschließt. Gegen die kraftbeaufschlagte Rückhalteklappe bildet sich ein Fadenpfropfen aus, der sobald der Pfropfendruck die Gegenkraft der Rückhalteklappe überschreitet, die Stauchkammer wieder verlässt. Die Höhe des Rückhalteklappenwiderstandes bestimmt dabei die Intensität der im Pfropfen gebildeten dreidimensionalen Verformung, d.h. die Intensität des Friezecharakters. Die Beeinflussung der Intensität des Friezecharakters erfolgt über die Veränderung der Rückhalteklappenkraft.As already described, the Friezevorrichtung is designed for example as stuffer box. In this case, the thread is conveyed by the delivery mechanism into a chamber in which a wall segment is set under load (for example by spring force or compressed air) and closes the space. A Fadenpfropfen forms against the force-loaded retaining flap, which as soon as the plug pressure exceeds the counterforce of the retaining flap leaves the compression chamber again. The height of the retaining flap resistance thereby determines the intensity of the three-dimensional deformation formed in the plug, i. the intensity of the frieze character. The influence of the intensity of the frieze character is achieved by changing the retention flap force.
Das verformte Frieze-Garn wird mittels eines trichterförmigen Elements, beispielsweise eines Rohrkrümmers, dessen Austrittsöffnung feststeht und in Richtung der Transporteinrichtung zeigt, kontrolliert abgelegt. Dabei rutscht das gebildete Frieze-Garn unter seinem Eigengewicht und infolge des kontinuierlichen Nachschubs im Inneren des Rohrkrümmers nach unten und legt sich auf das laufende Transportband.The deformed Frieze yarn is deposited in a controlled manner by means of a funnel-shaped element, for example a pipe elbow, whose outlet opening is fixed and points in the direction of the transport device. In this case, the formed Frieze yarn slides down under its own weight and as a result of the continuous supply in the interior of the elbow and lies down on the moving conveyor belt.
Im Falle des Wechsels zur Erzeugung von Straight Set-Garn wird die Rückhalteklappe mittels einer geeigneten Ansteuerung in die hintere Position gestellt und verbleibt dort für die gesamte Produktionszeit. Auf diese Weise entsteht eine hindernisfreie Kammer, durch die der Faden ablenkungsfrei läuft.In the case of change to the production of straight set yarn, the retaining flap is placed in the rear position by means of a suitable control and remains there for the entire production time. In this way creates a barrier-free chamber through which the thread runs distraction-free.
Gleichzeitig wird das trichterförmige Element mittels eines Antriebs, beispielsweise eines Schrittmotors, rotatorisch angetrieben. Der Faden wird damit aus dem Lieferwerk kommend über die entstehende Fliehkraftwirkung nach außen geschleudert und läuft innerhalb der Stauchkammer gestreckt. In Kombination von Fliehkraft und Eigengewicht des Fadens legt sich der Faden auf der Transportvorrichtung geordnet in Kreisbogenform ab. Der Ablegeradius, der aus der Höhe der Fliehkraft, des Eigengewichtes des Fadens und der Transportbandgeschwindigkeit beeinflusst wird, wird dabei so groß eingestellt, dass sich die Kreisbogigkeit immer noch als quasi gerade (Straight) in den Garnnoppen des fertigen Teppichs darstellt.At the same time, the funnel-shaped element is driven in rotation by means of a drive, for example a stepping motor. The thread is thus thrown out of the delivery unit on the resulting centrifugal force to the outside and runs stretched within the stuffer box. In combination of centrifugal force and weight of the thread, the thread lays on the transport device ordered in a circular arc form. The Ablegeradius, which is influenced by the amount of centrifugal force, the weight of the thread and the conveyor belt speed, it is so large set that the circularity still as quasi straight (Straight) in the yarn knots of the finished carpet represents.
Nach Anspruch 5 ist die Behandlungsvorrichtung eine Färbeeinrichtung.According to
Soll der Faden kontinuierlich gefärbt werden, so kann eine entsprechende und an sich bekannte Vorrichtung in dem abgeschlossenen System angeordnet sein. Nachdem der Faden durch eine Färbeflotte und Abquetschwalzen gezogen wurde, erfolgt die Ablage auf dem Transportband.If the thread is to be dyed continuously, then a corresponding device known per se can be arranged in the closed system. After the thread has been pulled through a dyeing liquor and squeezing rollers, it is deposited on the conveyor belt.
Vorzugsweise sind gemäß der Ansprüche 6 und 7 in der Längenausgleichseinrichtung sowohl Mittel zur Auflösung der bei der Formgebung und Ablage auf der Transporteinrichtung erzeugten komprimierten Fadenablage vorgelagert als auch eine Regeleinrichtung vorgesehen, die unter Berücksichtigung materialspezifischer Eigenschaften des fadenförmigen Gutes dafür sorgt, dass Lieferschwankungen des fadenförmigen Gutes ausgeglichen werden und der Abzug des fadenförmigen Gutes zum Verlassen des Systems weitestgehend gleichmäßig erfolgt.Preferably, according to the
Da der Faden nach der Fixierung das System zur Weiterverarbeitung gestreckt verlassen sollte, muss der Faden in den gestreckten Zustand gebracht werden. Die Streckung wird erzeugt über eine Längenausgleichseinrichtung, zum Beispiel einen Schlaufenspeicher mit einem Belastungsgewicht, womit eine Fadenzugkraft zwischen Ausgangslieferwerk und einem Abbindepunkt auf dem Transportband entsteht. Der Abbindepunkt auf dem Transportband kann mit einer frei drehbar gelagerten Walze mit definierter Linienlast, bestehend aus dem Walzengewicht plus gegebenenfalls eine Feder, definiert werden. Diese Walze bildet eine Abbindung zum davor befindlichen Transportbandstück, so dass nur das jeweilige Fadenstück, das gerade die Drucklinie durchläuft, durch das Gewicht im Schlaufenspeicher gestreckt wird. Bei einer kreisbogigen Ablage im Falle der Straight-Garn-Erzeugung wird immer ein ganzer Bogen freigegeben. Im Falle der Frieze-Garne wird die dreidimensionale Bogigkeit ausgestreckt. Der Garnspeicher ist für beide Fälle auf die maximal freiwerdende Fadenlänge ausgelegt.Since the thread should leave the system stretched for further processing after fixing, the thread must be brought into the stretched state. The stretching is produced by means of a length compensation device, for example a loop store with a loading weight, whereby a thread tension is created between the starting delivery station and a binding point on the conveyor belt. The setting point on the conveyor belt can be defined with a freely rotatably mounted roller with a defined line load, consisting of the roll weight plus optionally a spring. This roller forms a bond to the conveyor belt piece located in front of it, so that only the respective piece of thread that is just passing through the pressure line is stretched by the weight in the loop store. In a circular-arched tray in the case of straight-yarn production, a whole arc is always released. In the case of the Frieze yarns, the three-dimensional bow is stretched out. The yarn storage is designed for both cases to the maximum released thread length.
Im Falle des erläuterten Gewichtsspeichers erfolgt also eine permanente Auf-und-ab-Bewegung, im Falle der Straight-Garn-Herstellung durch die jeweils freiwerdende Länge eines ganzen Ablagebogens. Die Lage des Belastungsgewichtes wird mittels geeigneter Sensoren, bevorzugt berührungsloser Sensorik (z.B. Hallsensoren oder optische Sensoren), abgetastet. Hier können Sensoren eingesetzt werden, die kontinuierlich die exakte Lage über den gesamten möglichen Verfahrhub erfassen. Eine mögliche einfache Variante ist eine Zweistellungserkennung, wobei eine geeignete Software bei Erreichen des unteren Sensors das Ausgangslieferwerk etwas schneller laufen lassen kann und bei Erreichen des oberen Sensors das Ausgangslieferwerk langsamer ansteuern kann. Durch eine Anpassung der Regelalgorithmen kann abhängig vom Fadenmaterial und seinen Schrumpfeigenschaften sowie dem Ablageverhalten bzw. der Belegungsdichte auf dem Band die überlagerte Auf- und Abwärtsbewegung durch die freiwerdende Überlänge hinter dem Abbindepunkt kompensiert werden, um trotzdem ein verwertbares Regelverhalten sicherzustellen.In the case of the explained weight memory thus takes place a permanent up-and-down movement, in the case of straight yarn production by the respective liberated length of a whole storage sheet. The position of the load weight is scanned by means of suitable sensors, preferably non-contact sensors (for example Hall sensors or optical sensors). Here, sensors can be used, which continuously record the exact position over the entire possible travel. A possible simple variant is a two-position recognition, whereby a suitable software can let the output supply work a little faster when the lower sensor is reached and, when the upper sensor is reached, can drive the output supply unit more slowly. By adapting the control algorithms can be compensated depending on the thread material and its shrinkage properties and the deposition behavior or the density on the tape, the superimposed up and down movement by the liberated excess length behind the Abbindepunkt to still ensure a usable control behavior.
Das so entschlaufte beziehungsweise gestreckte Garn wird dann mittels des Ausgangslieferwerkes zur Ausgangsschleuse geführt und mittels eines außerhalb des Systems angeordneten Hauptabzuges durch die Auslassfadenschleuse gezogen.The so entschlaufte or stretched yarn is then guided by the Ausgangslieferwerkes to the exit lock and pulled by means of a arranged outside the system main trigger through the Auslassfadenschleuse.
Anspruch 8 besagt, dass einzelne Untersysteme eine bauliche Einheit bilden und aus dem abgeschlossenen System entnehmbar sind.
Durch die Untersysteme lässt sich das gesamte System als ein Baukastensystem konfigurieren. Einzelne Untersysteme wie beispielsweise die Behandlungsvorrichtung können so ausgetauscht oder zu Wartungszwecken aus dem Gesamtsystem entnommen werden.The subsystems allow the entire system to be configured as a modular system. Individual subsystems such as the treatment device can thus be replaced or removed for maintenance purposes from the overall system.
In einer besonderen Ausführungsform sind mehrere Untersysteme auf einem Halter, wie zum Beispiel einem Schlitten, zusammenmontiert. Dieser Schlitten befindet sich als Ganzes in einem unter Druckluft, der weitestgehend dem Systemdruck entspricht, stehenden Gehäuse. Vorteilhaft ist diese Lösung deshalb, weil die gesamte Einheit für Wartungszwecke und Reinigung als Schublade nach vorne gezogen werden kann.In a particular embodiment, multiple subsystems are mounted together on a holder, such as a carriage. This slide is as a whole in a compressed air, which largely corresponds to the system pressure, standing housing. Advantageously, this solution is because the entire unit for maintenance and cleaning as a drawer can be pulled forward.
Wie in Anspruch 9 beschrieben, sind die Versorgungseinrichtungen an eine zentrale Versorgung angeschlossen.As described in
Bei textilen Vielstellenmaschinen bietet es sich an, die Zuspeisung des Sattdampfes und der Druckluft zentral zu realisieren und davon die bedarfsgerechte Zuteilung zu den einzelnen Arbeitsstellen abzuzweigen.In the case of textile multiple-station machines, it makes sense to realize the feed of the saturated steam and the compressed air centrally and to divert the demand-based allocation to the individual workstations.
Besonders bevorzugt sind gemäß Anspruch 10 Systemparameter einstellbar.System parameters can be set particularly preferably according to
Entweder können an der Zentralsteuereinheit oder lokal an den jeweiligen Arbeitsstellenrechnern die Systemparameter, wie zum Beispiel die Liefergeschwindigkeiten, die Transportbandgeschwindigkeit, die Rotationsgeschwindigkeit des Ablagerohres, die Luftdrücke sowie die Temperaturen eingegeben werden.Either the system parameters, such as the delivery speeds, the conveyor belt speed, the rotation speed of the storage pipe, the air pressures and the temperatures can be entered at the central control unit or locally at the respective workstation computers.
Gegebenenfalls, falls eine Vorrichtung gemäß Anspruch 4 zum Einsatz kommt, gehören zu den Systemparametern ebenfalls die Auswahl, ob ein Frieze- oder Straight-Effekt erzielt werden soll und in welchem Ausmaß der Frieze-Effekt sich ausbildet. Auf diese Weise ist es möglich, das System auf materialspezifische Besonderheiten einzustellen und so unterschiedlichste Materialien verarbeiten zu können.If necessary, if a device according to
Je nach Anforderungsprofil können die Systemparameter entweder für die gesamte Maschine, für einzelne Maschinenseiten, für Sektionen oder individuell für jede Arbeitsstelle vorgegeben werden.Depending on the requirement profile, the system parameters can be specified either for the entire machine, for individual machine pages, for sections or individually for each workstation.
Nach Anspruch 11 sind Mittel zur automatischen Einfädelung des fadenförmigen Gutes vorgesehen.According to claim 11 means for automatically threading the thread-like material are provided.
Bis auf Röhrchenschleusen, durch die der Faden vorzugsweise manuell eingezogen werden muss, ist eine automatische Einfädelung, beispielsweise mittels Druckluft, vorgesehen.Except for tube locks through which the thread is preferably drawn in manually must be, an automatic threading, for example by means of compressed air, is provided.
Wie in den Ansprüchen 12 und 13 beschrieben, kann die Vorrichtung sowohl in den Fadenlauf von Fadenherstellungsprozessen- oder Fadenverarbeitungsprozessen integriert oder autark betrieben werden. Besonders geeignet ist die Vorrichtung für die Veredlung von Teppichgarnen. Daher kann insbesondere die erfindungsgemäße Vorrichtung in den Fadenlauf von Kablier- oder Zwirnmaschinen integriert werden. Denkbar wäre aber auch eine Anordnung beispielsweise vor einer Tuftingmaschine, in einer Spinnmaschine oder einem Extruder nachgeschaltet oder einer anderen fadenförmiges Gut verarbeitenden Textilmaschine.As described in
Gemäß Anspruch 14 bzw. Anspruch 15 kann die Vorrichtung für Einzelfäden eingesetzt werden, möglich ist aber auch, dass eine Fadenschar in das System zur Erzielung eines Effektes und dessen Fixierung geführt wird.According to claim 14 or
In diesem Fall werden mehrere Garnschleusen oder statt der Garnschleusen entsprechende, bekannte Trennmittel wie beispielsweise Abquetschwalzen zur Abdichtung verwendet.In this case, several yarn locks or instead of the yarn locks corresponding, known release agents such as squeeze rolls are used for sealing.

Das bedeutet, der Faden 1 läuft unbehandelt in das System 5 ein und verlässt das System 5 fertig veredelt.This means that the

Der Faden 1 wird über ein Lieferwerk 10 durch die Eingangsschleuse 4 in das System 5 gezogen. Der Faden 1 wird kontinuierlich in eine Stauchkammer 11 gefördert und am Ausgang gegen eine federbelastete Rückhalteklappe 12, die den Ausgang der Stauchkammer 11 verschließt, gedrückt. Durch den mechanischen Staudruck in der Stauchkammer 11 wird der Faden 1 in geometrisch unregelmäßiger Art und Weise dreidimensional gebogen und/oder geknickt (gekräuselt). Die in der Stauchkammer 11, auch Stuffer Box genannt, gekräuselte Fadenschar bildet gegen die kraftbeaufschlagte Rückhalteklappe 12 ein Fadenpfropfen aus, der sobald der Pfropfendruck die Gegenkraft der Rückhalteklappe 12 überschreitet, die Stauchkammer wieder verlässt. Unter anderem bestimmt die Höhe des Rückhalteklappenwiderstandes dabei die Intensität der im Pfropfen gebildeten dreidimensionalen Verformung d.h. die Intensität des Friezecharakters.The
Das nächste Untersystem 36 gewährleistet die kontrollierte Ablage auf eine Transporteinrichtung (z.B. einem Transportband). Von der Stauchkammer 11 aus läuft der Faden 1 durch ein Ablagerohr 13, dessen Austrittsöffnung feststeht und in Richtung des Transportbandes 14 zeigt. Das gebildete Friezegarn rutscht unter seinem Eigengewicht und infolge des kontinuierlichen Nachschubs im inneren des Ablagerohres nach unten und legt sich auf das Transportband 14.The
Darauf folgt das Untersystem der Dampfzone 32. Der abgelegte Faden 1 durchläuft auf dem Transportband 14 mit definierter Geschwindigkeit eine Trennstelle 39 und gelangt in die Dampfzone 32. Dort erfolgt die Erwärmung auf die so genannte Thermofixiertemperatur oder Bauschtemperatur, in der Praxis üblicherweise mittels Sattdampf oder überhitztem Dampf. Dabei erfährt der Faden einen materialbedingten Schrumpf und Bausch.This is followed by the subsystem of the
Zur Stabilisierung der Dampfzone 32 sind entsprechende mechanische Trennelemente 39, hier eine Schlitzblende, vorgesehen. Darüber hinaus wird die vorgeschaltete Druckluftzone 31 bzw. nachgeschaltete Kühlzone 33 mit Druckluft und einem im Wesentlichen dem Dampfdruck entsprechendem Druck beaufschlagt. Beides sichert einen geringen Medienaustausch zwischen den einzelnen Zonen.To stabilize the
In dem folgenden Untersystem Kühlzone 33 wird der Faden 1 mittels Druckluft bis unter die materialspezifische Glasumwandlungstemperatur gekühlt, damit der in der Dampfzone 32 vorliegende Zustand permanent stabilisiert bzw. fixiert wird und somit gegen mechanische Belastungen in Folgeprozessen, wie zum Beispiel beim Aufspulen, Tuften oder Weben und im fertigen Teppich widerstandsfähig wird.In the following
Da der Faden 1 anschließend das System 5 zur Weiterverarbeitung und Aufwicklung auf eine Spule gestreckt verlassen sollte, muss der Faden 1 wieder in den gestreckten Zustand gebracht werden. Die Streckung wird erzeugt über einen Schlaufenspeicher 20 mit einem Belastungsgewicht 42, womit eine Fadenzugkraft zwischen Ausgangslieferwerk 24 und einem Abbindepunkt auf dem Transportband 14 erzeugt wird.Since the
Im Faden- bzw. Schlaufenspeicher 20 erfolgt eine permanente Auf-und-ab-Bewegung, im Falle der Straight Set-Garn-Herstellung durch die jeweils freiwerdende Länge eines ganzen Ablagebogens. Die Lage des Belastungsgewichtes 42 wird mittels geeigneter Hallsensoren 21, 22 abgetastet. Mittels einer Zweistellungserkennung wird das Abzugslieferwerk 24 angesteuert, wobei die Steuerung 44 bei Erreichen des unteren Sensors 21 das Abzugslieferwerk 24 etwas schneller laufen lässt und bei Erreichen des oberen Sensors 22 das Abzugslieferwerk 24 langsamer ansteuert.In the thread or
Der nun entschlaufte Faden 1 wird dann mittels des Ausgangslieferwerkes 24 zur Ausgangsschleuse 6 geführt und mittels eines Hauptabzuges hindurch gezogen.The now
Das System 5 wird über den Einlass für Druckluft 25, dem Einlass für Sattdampf 26 und dem Einlass für Druckluft für die Kühlzone 27 versorgt. Zusammen mit dem Auslass für Luft 28, dem Auslass für Dampf/Kondensat 29 und dem Auslass für Luft aus der Kühlzone 30 ist eine kontinuierliche Ver- und Entsorgung des Systems 5 gewährleistet.The
Als Besonderheit weist das Ablagerohr 13 einen (nicht dargestellten) Antrieb auf, beispielsweise einen Schrittmotor. Im Falle der Erzeugung von Straight Set-Garn wird im Untersystem Effekterzeugung 35 die Rückhalteklappe 12, die mit einem Gelenk an der Wand der Stauchkammer 11 angebracht ist, in die hintere Position gestellt und verbleibt dort für die gesamte Produktionszeit. Die Stauchkammer 11 ist auf diese Weise zu einer Führung ohne Behinderung für den durchlaufenden Faden 1 geworden. Gleichzeitig wird das Ablagerohr 13 rotatorisch angetrieben. Der Faden 1 wird damit aus dem Lieferwerk 10 kommend über die entstehende Fliehkraftwirkung nach außen geschleudert und läuft innerhalb der Stauchkammer 11 gestreckt. In Kombination von Fliehkraft und Eigengewicht des Fadens 1 legt sich der Faden 1 auf dem Transportband 14 geordnet in Kreisbogenform ab. Der Ablegeradius, der aus der Höhe der Fliehkraft, des Eigengewichtes des Fadens 1 und der Transportbandgeschwindigkeit beeinflusst wird, wird dabei so groß eingestellt, dass sich die Kreisbogigkeit immer noch als quasi gerade in den Garnnoppen des fertigen Teppichs darstellt.As a special feature, the
Auf diese Weise ist ein Wechsel von der Herstellung von Frieze-Garn auf Straight Set-Garn ohne Wechsel von mechanischen Bauelementen und ohne neues Einfädeln des Garnes möglich.In this way, a change from the production of Frieze yarn on straight set yarn without changing mechanical components and without re-threading the yarn is possible.
