Description

Die Erfindung bezieht sich auf ein Verfahren zum Sengen von Garnen gemäß dem Oberbegriff des Anspruchs 1 und eine Sengmaschine gemäß dem Oberbegriff des Anspruchs 2.The invention relates to a method for singeing of yarns according to the preamble of claim 1 and a singeing machine according to the preamble of the claim Second

Ein Beispiel einer Sengmaschine geht aus der EP 0 814 185 A2 hervor. Hierbei werden mehrere Garnstränge nebeneinander in ihrer Längsrichtung durch einen Sengkanal des Sengbrenners hindurchgeführt, der von einem Ende her mittels Gasflammen beheizt ist, deren Richtung im wesentlichen mit der des Sengkanals übereinstimmen, so daß sich also die Flaumigase und das Garn in dem Sengkanal gleichlaufend bewegen.An example of a singeing machine is given in EP 0 814 185 A2. Here, several skeins of thread are side by side in its longitudinal direction through a scorching canal of the singe burner passed by one End is heated by gas flames, their direction essentially coincide with that of the Sengkanal, so that the fluffy gas and the yarn move in the same direction in the singe channel.

Die Arbeitsgeschwindigkeit, d.h. die Geschwindigkeit, mit der die Garnstränge in ihrer Längsrichtung durch den Sengbrenner hindurchgefördert werden, liegt in der Größenordnung von 300 bis 1000 m/min. Das Sengen wird meist bei Garnen angewendet, aus deren Oberfläche feine Härchen vorstehen, also z.B. bei Garnen aus Naturfasern oder Spinnfasergarnen. Die aus der Garnoberfläche hervorstehenden Härchen werden abgebrannt bzw. schmelzen oder backen zu Partikeln zusammen, die zunächst die Geschwindigkeit der Garnstränge aufweisen und sich mit diesen in der gleichen Richtung fortbewegen. Das Sengergebnis des Sengbrenners nach der EP 0 814 185 A2, d.h. der Grad der Befreiung der Garnstränge von den durch die hervorstehenden Härchen gebildeten Flusen, ist ausgezeichnet. Bei der praktischen Verwirklichung einer Sengmaschine unter Einsatz von Senkbrennern der in der EP 0 814 185 A2 beschriebenen Art hat es jedoch anfänglich Schwierigkeiten gegeben, weil die abgesengten und mit dem Garnstrang mitfliegenden, zunächst noch flüssigen oder klebrigen Partikel eines thermoplastischen Materials die Neigung haben, sich überall im Ausgangsbereich der Maschine an den Wandungen und Führungselementen für die Garnstränge in dicken Schichten festzusetzen und wiederholte und schwierig durchzuführnde Reinigungsoperationen verursachen. Bei den angegebenen Arbeitsgeschwindigkeiten kommen im Dauerbetrieb nicht unerhebliche Mengen an abgesengtem Material zustande.The working speed, i.e. the speed, with the strands of yarn in their longitudinal direction the Sengbrenner are conveyed lies in of the order of 300 to 1000 m / min. The scorching is mostly applied to yarns from their surface protrude fine hairs, e.g. with yarns Natural fibers or spun yarns. The from the yarn surface protruding hairs are burned off or melt or bake into particles that first have the speed of the skeins and deal with these in the same direction move. The scorching result of the singe burner after EP 0 814 185 A2, i.e. the degree of exemption of the Skeins of yarn from the protruding hairs formed fluff is excellent. In the practical Realization of a scorching machine using of sink burners of the type described in EP 0 814 185 A2 Art initially has difficulties given because the seared and with the skein of thread flying, initially still liquid or sticky Particle of a thermoplastic material the inclination have themselves everywhere in the exit area of the machine on the walls and guide elements for the Thread skeins in thick layers and repeated and difficult cleaning operations to perform cause. At the specified working speeds come not inconsiderable in continuous operation Amounts of material seared.

Bei der gattungsgemäßen US-A-3 822 452 durchläuft der Garnstrang von oben nach unten eine etwa zylindrische Sengkammer, gegen deren Wandung die Sengflamme von außen gerichtet ist, deren Abgase an der Wandung um 180° umgelenkt und dann abgesaugt werden. Unter der Sengkammer befindet sich eine Einrichtung zum Auffangen und Entfernen der mit dem Garnstrang mitbewegten Partikel in Gestalt einer mit einem engen Durchlaß für den Garnstrang versehenen Auffangschale, die die Partikel daran hindert, in den Bereich der unter der Auffangschale angeordneten Aufwickelspule für den Garnstrang zu gelangen. In the generic US-A-3 822 452 passes through the Thread strand from top to bottom is approximately cylindrical Sengkammer, against whose wall the scorching flame of is directed outside, the exhaust gases around the wall Deflected 180 ° and then suctioned off. Under the Sengkammer is a device for collecting and removing those moving with the skein Particles in the form of one with a narrow passage for the skein provided drip tray, which the Prevents particles from entering the area under the Collecting tray arranged take-up reel for the Strand of yarn to arrive.

Diese Vorrichtung ist nur für Garne mit sehr wenig abzusengendem Material geeignet. Bei anderen Garnen, insbesondere Teppichgarnen, die dicker sind und eine erhebliche Haarigkeit aufweisen, ist die abzusengende und zu entfernende Materialmenge so groß, daß sich die Auffangschale, beginnend im Bereich des Durchlasses, sofort zusetzen würde.This device is only for yarns with very little suitable material to be cut. With other yarns especially carpet yarns that are thicker and one have considerable hairiness, is the one to be cut and the amount of material to be removed is so large that the drip tray, starting in the area of the culvert, would clog immediately.

Der Erfindung liegt daher die Aufgabe zugrunde, die Betriebsweise einer gattungsgemäßen Sengmaschine zu verbessern.The invention is therefore based on the object Operation of a generic singeing machine too improve.

Diese Aufgabe wird in ihrem verfahrensmäßigen Aspekt durch die in Anspruch 1, in ihrem vorrichtungsmäßigen Aspekt durch die in Anspruch 2 wiedergegebenen Erfindungen gelöst.This task is in its procedural aspect by the in claim 1, in their device Aspect by the inventions reproduced in claim 2 solved.

Die hierin zum Ausdruck kommende Grundidee besteht darin, die mitbewegten Partikel zu entfernen, so daß sie nirgends mehr aufprallen und anbacken können, sondern gesammelt und auf für den Betrieb der Sengmaschine unschädliche Weise entsorgt werden können.The basic idea expressed here is in removing the moving particles so that they cannot bounce and bake anywhere but collected and on for the operation of the scorching machine can be disposed of safely.

Der Garnstrang bzw. die Garnstränge einer Gruppe werden frei und berührungslos gegen die Öffnung des Behälters geführt. Dort sind die Umlenkrollen vorgesehen. Die Umlenkung an den Umlenkrollen erfolgt in einem spitzen Winkel. Etwa noch an dem Garn haftende Partikel werden durch diese abrupte Richtungsänderung abgeschleudert und gelangen ebenfalls in den Behälter, der die in einer Art Sprühstrahl mit dem Garnstrang mitfliegenden Partikel in einer Weise auffängt, daß sie aus der Maschine entfernbar sind, ohne die Maschine von innen zu bedecken und Führungselemente zu verkleben. Der Behälter hat für jeden Garnstrang oder jede Gruppe von Garnsträngen einen Öffnungsquerschnitt, der ausreicht, um die Gesamtheit der fliegenden abgesengten Partikel aufzunehmen.The skein or the skeins of a group free and contactless against the opening of the container guided. The pulleys are provided there. The deflection at the deflection rollers takes place in one acute angle. About still sticking to the yarn This abrupt change of direction causes particles to become particles thrown off and also get into the container, the one in a kind of spray with the Catches strand of flying particles in a way that they can be removed from the machine without cover the machine from the inside and guide elements to glue. The container has for everyone Thread or each group of thread strands one Opening cross-section that is sufficient to cover the whole of the flying seared particles.

Die in dem Sengbrenner abgesengten Materialpartikel werden zweckmäßig ebenso wie der einzelne Garnstrang selbst eine Zeitlang berührungslos durch die Luft geführt werden, damit durch Abkühlung eine Verfestigung der Partikel und der Garnoberfläche in einem Grade erreicht wird, daß keine Klebrigkeit mehr besteht, d.h. keine Neigung zum Anbacken oder Zusammenbacken mehr vorhanden ist. Die Partikel müssen nicht vollkommen hart werden, sollen aber an ihrer Oberfläche keine Neigung mehr zeigen, an einer benachbarten Oberfläche oder einer benachbarten Partikel anzuhaften.The material particles sunk in the singe burner are useful just like the single skein guided through the air without contact for a while become a solidification by cooling the particles and the yarn surface to a degree is achieved that there is no longer any stickiness, i.e. no tendency to cake or cake there is more. The particles don't have to be perfect become hard, but should be on their surface no longer show inclination on a neighboring one Surface or an adjacent particle.

Dies kann in der in Anspruch 3 wiedergegebenen Weise realisiert werden.This can in the manner set out in claim 3 will be realized.

Bei der bevorzugten Ausführungsform der Erfindung ist die konstruktive Anordnung nach Anspruch 4 getroffen.In the preferred embodiment of the invention made the constructive arrangement according to claim 4.

Die Vorsehung des Sengbrenners gewissermaßen in einer oberen "Ecke" des Gehäuses der Sengmaschine und die diagonale Führung der Garnstränge im Gehäusequerschnitt erlauben die Unterbringung einer maximalen Abkühlstrecke bei einem Gehäuse bestimmter Größe.The providence of the singe burner, so to speak, in one upper "corner" of the housing of the singeing machine and the diagonal guidance of the yarn strands in the housing cross-section allow the accommodation of a maximum Cooling section for a housing of a certain size.

Außerdem aber führt die schräge Garnstrangführung schon zu einer ersten Trennung der mitbewegten abgesengten Partikel von den Garnsträngen, weil die Partikel unter Schwerewirkung eine parabelförmige Flugbahn nach unten zurücklegen. Die Öffnung des Behälters muß sich über den gesamten Grundrißbereich erstrecken, in dem die fliegenden bzw. fallenden abgesengten Partikel ankommen können. Ein gefüllter Behälter kann während des Betriebs der Sengmaschien rasch gegen einen leeren Behälter ausgetauscht werden.In addition, however, the sloping yarn strand guide already for a first separation of the co-sunk Particles from the skeins of thread because of the particles a parabolic trajectory under gravity put down. The opening of the container must extend over the entire floor plan area, in which the flying or falling seared Particles can arrive. A filled container can during the operation of the singeing machines can be quickly replaced with an empty container.

Nach einem weiteren Merkmal der bevorzugten Ausführungsform gemäß Anspruch 5 wird das Ende der Kühlstrecke durch die Umlenkrollen gebildet, an denen der Garnstrang bzw. die Garnstränge in einer Aufwärtsstrecke umgelenkt werden, um aus dem Bereich der Öffnung des Behälters wegzukommen und weitergeleitet werden können. In der Aufwärtsstrecke findet noch eine merkliche Nachkühlung statt, so daß die Garnstränge sich bis zu ihrer Weiterförderung zu einem nachgeschalteten Aggregat weiter abkühlen können.According to another feature of the preferred embodiment according to claim 5, the end of Cooling section formed by the pulleys on which the skein or strands of yarn in an upward stretch to be redirected to out of the range of Opening the container to get away and forwarded can be. There is another in the upward stretch noticeable post-cooling instead, so that the skeins of yarn up to their further promotion to a downstream one Allow the unit to cool down further.

Als ein konstruktives Beispiel ist in Anspruch 6 eine Länge der Aufwärtsstrecke von einem Dritten bis zwei Drittel der Länge der Abkühlstrecke genannt.As a constructive example in claim 6 is one Length of the uplink from a third to two Called third of the length of the cooling section.

Am oberen Ende der Aufwärtsstrecke können gemäß Anspruch 7 weitere Umlenkrollen vorhanden sein, mittels derer der Garnstrang oder die Garnstränge aus dem Gehäuse der Sengmaschine herausgeleitet werden können.At the upper end of the uplink, according to claim 7 further pulleys are available by means of which the skein or the skeins of thread from the housing the scorching machine can be led out.

Die Länge der Abkühlstrecke sollte mindestens 1,20 m betragen (Anspruch 8).The length of the cooling section should be at least 1.20 m amount (claim 8).

Die je nach Arbeitsgeschwindigkeit für die Zurücklegung dieser Strecke benötigte Zeit reicht aus, um die relativ kleinen abgesengten Partikel oberflächlich so weit abkühlen zu lassen, daß sie ihre Klebrigkeit verlieren.Depending on the speed of work for the journey this distance is sufficient to complete the relatively small particles on the surface like that to let it cool off its stickiness to lose.

Der Schrägstellungswinkel des Garnstrangs bzw. der Garnstränge in der Abkühlstrecke hängt von den konstruktiven Gegebenheiten ab. Gemäß Anspruch 9 sollte er 45° bis 75° betragen. The skew angle of the skein or Yarn strands in the cooling section depend on the constructive Circumstances. According to claim 9 should he be 45 ° to 75 °.

Die am Ende der Abkühlstrecke und auch am Ende der Aufwärtsstrecke vorgesehenen Umlenkrollen für jeden einzelnen Garnstrang sollten im Anlagebereich des Garnstrangs, z.B. im Grund einer etwa vorhandenen Führungsrille, Durchmesser von etwa 15 bis 30 mm aufweisen (Anspruch 10), wodurch die Umlenkrollen bei Garngeschwindigkeiten von 300 bis 1000 m/min sehr hohe Drehzahlen in der Größenordnung von ca. 5.000 bis 20.000 min-1 erhalten, was dazu führt, daß etwa zum Anbacken neigende angesengte Partikel abgeschleudert werden. Die Umlenkrollen können auf diese Weise sauber gehalten werden.The deflection rollers provided for each individual yarn strand at the end of the cooling section and also at the end of the upward section should have a diameter of about 15 to 30 mm in the area of contact of the yarn strand, for example in the presence of an existing guide groove (claim 10), so that the deflection rollers at yarn speeds of Obtain 300 to 1000 m / min very high speeds in the order of approximately 5,000 to 20,000 min -1 , which leads to the fact that singeed particles that tend to stick are thrown off. The deflection rollers can be kept clean in this way.

Um auch Abstützungen der Umlenkrollen vor anbackenden Partikeln zu schützen, empfiehlt sich die Ausgestaltung nach Anspruch 11. Die Abstützungen sind auf diese Weise aus dem Bereich des Garns und der abgesengten Partikel herausgerückt.To also support the deflection rollers against caking The design is recommended to protect particles according to claim 11. The supports are on this Way from the area of the yarn and the seared Particles moved out.

Die Ansprüche 12 bis 15 geben konstruktive Ausgestaltungen der Umlenkrollen und ihrer Wellen wieder.The claims 12 to 15 give constructive refinements the pulleys and their shafts again.

Es ist von Vorteil, wenn in der Abkühlstrecke oberhalb des Garnstrangs eine Absaugeinrichtung für aus dem Sengbrenner austretende Flammgase vorgesehen ist (Anspruch 16).It is advantageous if in the cooling section above of the yarn strand a suction device for the flame gas escaping the singe burner is provided (Claim 16).

Auf diese Weise können die Flammgase aus dem Gehäuse der Sengmaschine herausgeführt werden. Die Flammgase haben durch ihre Temperatur die Neigung, nach oben, der Absaugeinrichtung entgegen, zu steigen. Zusammen mit dem Umstand, daß die abgesengten Partikel unter der Schwerewirkung nach unten fallen, wird hierdurch die Trennung der Flammgase von den abgesengten Partikeln gefördert. In this way, the flame gases from the housing the scorching machine. The flame gases are inclined upwards by their temperature, towards the suction device to rise. Together with the fact that the seared particles under the effect of gravity will fall down the separation of the flame gases from the seared particles promoted.

Je nach Arbeitsgeschwindigkeit und Art des Garnmaterials kann es sich empfehlen, gemäß Anspruch 17 im Bereich der Abkühlstrecke eine Sprüheinrichtung vorzusehen, mittels derer ein fluides Medium auf den laufenden Garnstrang sprühbar ist.Depending on the speed of work and the type of yarn material it can be recommended, according to claim 17 To provide a spraying device in the area of the cooling section, by means of which a fluid medium on the running thread strand is sprayable.

Das fluide Medium kann Luft, Wasser oder dergleichen sein und die Abkühlung unterstützen.The fluid medium can be air, water or the like be and support the cooling.

Der Gegenstand des Anspruchs 18, nämlich die Regelung der Sengwirkung über eine Temperaturmessung, wirkt im Sinne einer optimalen Abtrennung der mitbewegten abgesengten Partikel mit, insofern auf diesem Wege jede übermäßige Temperatursteigerung über den für das Sengen notwendigen Wert vermieden und die Abkühlstrecke tatsächlich eine Abkühlung bis zu einer ausreichenden Verfestigung der Partikel ergibt.The subject of claim 18, namely the regulation the scorching effect via a temperature measurement, acts in the In the sense of an optimal separation of the co-moved seared Particles with, in this way each excessive temperature rise above that for singeing necessary value avoided and the cooling section actually cooling down to a sufficient level Solidification of the particles results.

The skeins of yarn are brought up at 4 and in Interior of the machine housing 1 at 5 by appropriate Deflection pulleys not shown in detail at an angle redirected below. The skeins 3 then pass in the gas-heated singe burner one level above the other 10, the gas flames at the end 6 of the singe burner 10 are generated and one parallel to the conveying direction 7 of the yarn strands 3 extending flame direction exhibit. The flame gases occur at the inlet end 6 opposite end 8 together with the skeins of yarn 3 in the direction 7 from the singe burner 10.

    Der Sengbrenner 10 jeder Brennereinheit 2 ist im Bereich der in Fig. 1 rechten oberen Ecke des dargestellten Gehäusequerschnitts angeordnet, der im wesentlichen die Gestalt eines aufrechten Rechtecks aufweist. Die Förderrichtung 7 erstreckt sich schräg nach unten, d.h. etwa diagonal zu dem dargestellten Gehäusequerschnitt bis zu im Bereich der linken unteren Ecke des Gehäusequerschnitt gelegenen, in Fig. 1 nur angedeuteten, in Fig. 3 und 4im einzelnen dargestellten Umlenkrollen 9. In dem Ausführungsbeispiel nehmen die von den oberen Umlenkrollen 5 bis zu den unteren Umlenkrollen 9 geradlinig und berührungslose verlaufenden Garnstränge 3 mit der Horizontalen einen Winkel 11 von etwa 60° ein. An den Umlenkrollen 9 erfolgt eine Umlenkung nach oben in einem spitzen Winkel 12 bis zu oberen Umlenkrollen 13, an denen die Garnstränge 3 aus dem Gehäuse 1 in Sinne des Pfeiles 14 herausgeleitet werden.The singe burner 10 of each burner unit 2 is in the area the upper right corner of the housing cross section shown in FIG. 1 arranged, which is essentially the Has the shape of an upright rectangle. The direction of funding 7 extends obliquely downwards, i.e. approximately diagonally to the housing cross section shown up to Area of the lower left corner of the housing cross section located, only indicated in Fig. 1, in Fig. 3 and 4im individually shown deflection rollers 9. In the embodiment take the from the upper pulleys 5 to to the lower pulleys 9 straight and contactless running strands of yarn 3 with the horizontal one Angle 11 of about 60 °. On the pulleys 9 a redirection upwards at an acute angle 12 up to upper pulleys 13, on which the skeins 3 from the Housing 1 are led out in the direction of arrow 14.

    Zwischen der Austrittsstelle 8 aus dem Sengbrenner 10 legen die Garnstränge 3 bis zu den Umlenkrollen 9 eine Abkühlstrecke 15 zurück, die in einem konkreten Ausführungsbeispiel eine Länge von etwa 1,40 m aufweist. An die Abkühlstrecke 15 schließt sich eine Aufwärtsstrecke 16 an, die in dem Ausführungsbeispiel etwa halb so lang ist.Between the exit point 8 from the singe burner 10 lay the skeins 3 up to the pulleys 9 Cooling section 15 back in a specific embodiment has a length of about 1.40 m. To the Cooling section 15 is followed by an upward section 16, which is about half as long in the exemplary embodiment.

    Die Garnstränge 3 bestehen in dem Ausführungsbeispiel aus einem thermoplastischen Spinnfaser-Teppichgarn, auf dessen Oberfläche im ungesengten Zustand feine Härchen hervorstehen, die bei der Ausrüstung des Teppichs und auch noch bei seiner nachfolgenden Ingebrauchnahme eine sehr störende Flusenbildung verursachen. Die vorstehenden Härchen werden beim Passieren des Sengbrenners 10, in welchem eine sehr hohe Temperatur herrscht, abgebrannt bzw. abgeschmolzen und fliegen zusammen mit den Garnsträngen 3 in der Richtung 7 mit. Im Bereich des Austrittsendes 8 des Sengbrenners 10 sind die abgesengten Partikel noch klebrigplastisch, kühlen sich aber auf der Abkühlstrecke 15 soweit ab, daß sie zumindest an der Oberfläche ihre Klebrigkeit verlieren und nicht mehr die Neigung besitzen, an einer Aufprallfläche oder einer anderen Partikel anzuhaften.The skeins of yarn 3 consist in the embodiment a thermoplastic staple carpet yarn, on the Protruding fine hairs in the unsengaged state, the equipment of the carpet and also a very annoying when it is subsequently used Cause fluff to form. The above hairs are when passing the singe burner 10, in which a the temperature is very high, burned down or melted down and fly together with the skeins 3 in the Direction 7 with. In the area of the outlet end 8 of the singe burner 10 the seared particles are still sticky plastic, but cool so far on the cooling section 15 from that they at least on the surface their stickiness lose and no longer have the tendency to stick to an impact surface or other particle.
