Description

Die Erfindung betrifft eine Vorrichtung zum Zwischenspeichern von Garn mit einem Bandförderer mit Antriebsvorrichtung, einem Wickelkopf mit einem auf einer Kreisbahn geführtten Fadenführer, durch den das Garn in Form von Schlingen nach Art einer Schraubenwendel auf den Bandförderer an dessen in Transportrichtung vorderem Ende gelegt wird, einen Mast mit im wesentlichen sich in Längsrichtung des Masts erstreckenden, um den Mast herum angeordneten Fördermitteln, auf die durch den Wickelkopf die Garnschlingen derart auflegbar sind, daß sich beim Betrieb der Vorrichtung der Mast mindestens zu einem Teil seiner Länge innerhalb der Garnschlingen befindet, mit einer Vorrichtung zum Abziehen des Garns am hinteren Ende des Bandförderers, wobei zum Antrieb des Bandförderers ein in Bewegungsrichtung des Bandförderers beweglich angetriebenes Antriebsglied vorgesehen ist, das mit dem Förderband des Bandförderers oder einem mit diesem gekoppelten Antriebsteil in Reibkontakt ist, wobei die Bewegungsgeschwindigkeit des Antriebsglieds in Transportrichtung des Bandförderers etwa dessen Transportgeschwindigkeit entspricht.The invention relates to a device for temporarily storing yarn with a belt conveyor with a drive device, a winding head with a thread guide guided on a circular path, through which the yarn is placed in the form of loops in the manner of a helical coil on the belt conveyor at its front end in the transport direction, one Mast with essentially extending in the longitudinal direction of the mast, arranged around the mast conveying means onto which the twine loops can be placed by the winding head in such a way that during operation of the device the mast is at least part of its length within the twine loops, with a Device for pulling the yarn at the rear end of the belt conveyor, wherein a drive member movably driven in the direction of movement of the belt conveyor is provided for driving the belt conveyor, which is in frictional contact with the conveyor belt of the belt conveyor or with a drive part coupled to the latter, the movement g Speed of the drive member in the transport direction of the belt conveyor corresponds approximately to its transport speed.

Eine derartige Vorrichtung ist durch die DE-C-2 040 361 im wesentlichen bekannt. Bei der bekannten Vorrichtung ist zum Antrieb des Bandförderers von einem außerhalb des Bandförderers angeordneten Motor her eine Welle, die unmittelbar den Fadenführer antreibt, ins Innere eines Gehäuses eingeführt, das Teil des Bandförderers ist und das auf der Welle drehbar gelagert ist. Das Gehäuse enthält ein Schneckenrad-Zahnradgetriebe, das durch die rotierende Welle angetrieben wird und Keilriemen antreibt, die wiederum die Förderbänder des Bandförderers antreiben. Die Keilriemen liegen innen an den Förderbändern an, wogegen die Schlingen außen auf die Förderbänder aufgelegt werden. Um ein Verdrehen des an sich drehbar gelagerten Gehäuaes zu verhindern, liegen außerhalb der Schlingen angeordnete, an einem ortsfesten Maschinengestell gelagerte Stützrollen an den Förderbändern im Bereich der Keilriemen an, wobei die Stützrollen von den Förderbändern durch die durch die Schlingen definierte Ebene hindurch durch Reibkontakt mitgedreht werden und wobei die Keilriemen durch am Gehäuse angeordnete Gegendruckrollen an dieser Stelle abgestützt werden.Such a device is essentially known from DE-C-2 040 361. In the known device for driving the belt conveyor from a motor arranged outside the belt conveyor, a shaft which drives the thread guide directly is inserted into the interior of a housing which is part of the belt conveyor and which is rotatably mounted on the shaft. The housing contains a worm gear gear drive which is driven by the rotating shaft and drives V-belts which in turn drive the conveyor belts of the belt conveyor. The V-belts lie on the inside of the conveyor belts, whereas the loops are placed on the outside of the conveyor belts. In order to prevent the housing, which is rotatably mounted per se, from rotating, support rollers arranged outside of the loops and supported on a stationary machine frame lie against the conveyor belts in the region of the V-belts, the support rollers being rotated by the conveyor belts through the plane defined by the loops through frictional contact and the V-belts are supported at this point by counter pressure rollers arranged on the housing.

Der Erfindung liegt die Aufgabe zugrunde, die eingangs geschilderte Vorrichtung, die ein Zahnradgetriebe innerhalb des Bandförderers benötigt, zu vereinfachen.The invention has for its object to simplify the device described above, which requires a gear transmission within the belt conveyor.

Diese Aufgabe wird gemäß der Erfindung dadurch gelöst, daß das Antriebsglied außerhalb der Schlingen angeordnet ist und durch die durch die Schlingen definierte Fläche hindurch mit dem Förderband oder dem mit dem Bandförderer gekoppelten Antriebsteil gekoppelt ist.This object is achieved according to the invention in that the drive member is arranged outside the loops and is coupled through the surface defined by the loops to the conveyor belt or to the drive part coupled to the belt conveyor.

Es ist zwar durch die DE-A-1 813 246 eine Vorrichtung für die kontinuierliche Behandlung von Garnen bekannt, die einen Bandförderer mit einem innerhalb von diesem angeordneten Mast aufweist, wobei durch einen Fadenführer das Garn in Form von Schlingen auf den Bandförderer aufgelegt wird und durch diesen transportiert wird und am anderen Ende abgezogen wird. Wie bei der eingangs beschriebenen bekannten Vorrichtung werden die Förderbänder des Bandförderers von einer den Fadenführer bewegenden Welle her über ein Getriebe des Bandförderers angetrieben. Im Bereich des freien Endes des Bandförderers sind die unteren Förderbänder zum zentralen Mast hin versetzt, so daß in diesem Bereich die Garnschlingen frei hängen. Der Mast weist an dieser Stelle eine Schiene mit konkaver, kreisbogenförmiger Bahn auf, an der sich die Arme eines sternförmigen, maschinenfest gelagerten, angetriebenen Stützrads mit am Ende der Arme angeordneten Rollen abstützen können. Das Stützrad soll mit den Enden seiner Arme zwischen einander benachbarten freihängenden Schlingen hindurchgreifen, damit die Rolle am Ende jedes Arms nur mit der Schiene in Berührung kommt und ohne Störung des Garns den Mast abstützen kann. Das Stützrad dient nicht dazu, irgendwelche Teile des Bandförderers anzutreiben.It is known from DE-A-1 813 246 a device for the continuous treatment of yarns which has a belt conveyor with a mast arranged inside it, the yarn being placed on the belt conveyor in the form of loops by a thread guide and is transported through this and is withdrawn at the other end. As in the known device described in the introduction, the conveyor belts of the belt conveyor are driven by a shaft moving the thread guide via a gear of the belt conveyor. In the area of the free end of the belt conveyor, the lower conveyor belts are offset towards the central mast, so that the yarn loops hang freely in this area. At this point, the mast has a rail with a concave, circular-arc-shaped path, on which the arms of a star-shaped, machine-mounted, driven support wheel with rollers arranged at the end of the arms can be supported. The support wheel should reach through with the ends of its arms between adjacent free hanging loops so that the roller at the end of each arm only comes into contact with the rail and can support the mast without disturbing the yarn. The jockey wheel is not used to drive any parts of the belt conveyor.

Der Vorteil der Erfindung liegt darin, daß kein im Bereich der Verankerung des Masts des Bandförderers angeordnetes Zahnradgetriebe erforderlich ist, da die Antriebskraft für das Förderband im einfachsten Fall unmittelbar auf dieses übertragen wird. Da eine allenfalls auftretende Geschwindigkeitsdifferenz zwischen dem Bandförderer und dem Antriebsglied relativ gering ist, schadet es nichts, wenn die auf den Bandförderer gelegten Schlingen mit dem Antriebsglied körperlich in Kontakt kommen. Wenn das Antriebsglied unmittelbar mit dem Förderband in Kontakt ist, wird, von einem möglicherweise auftretenden Schlupf abgesehen, im allgemeinen keine Geschwindigkeitsdifferenz vorhanden sein; eine Geschwindigkeitsdifferenz zwischen dem Antriebsglied und dem angetriebenen Teil ist aber dann möglich, wenn, wie später noch ausgeführt wird, das Antriebsglied beispielsweise mit einer innerhalb der durch die Schlingen definierten Fläche angeordneten Antriebsrolle in Kontakt ist.The advantage of the invention lies in the fact that no gear transmission arranged in the area of the anchoring of the mast of the belt conveyor is necessary, since in the simplest case the driving force for the conveyor belt is transmitted directly to it. Since any speed difference that occurs between the belt conveyor and the drive member is relatively small, it does no harm if the loops placed on the belt conveyor come into physical contact with the drive member. If the drive member is in direct contact with the conveyor belt, apart from a possible slip, there will generally be no speed difference; however, a speed difference between the drive member and the driven part is possible if, as will be explained later, the drive member is in contact, for example, with a drive roller arranged within the area defined by the loops.

Bei der Erfindung kann das rotierend angetriebene Antriebsglied insbesondere ein Rad sein. Es könnte aber auch nach Art eines Förderbandes ausgebildet sein, das im wesentlichen auf seiner ganzen Länge mit dem Trum des Förderbandes des Bandförderers in Eingriff ist, das die Schlingen hält. Unter dem Begriff Rad soll hier auch eine Walze verstanden sein, also ein Rad mit erheblicher Dicke in seiner Achsrichtung gemessen.In the invention, the rotatingly driven drive member can in particular be a wheel. However, it could also be designed in the manner of a conveyor belt which engages essentially over its entire length with the run of the conveyor belt of the belt conveyor which holds the loops. The term wheel is also to be understood here to mean a roller, that is to say a wheel with a considerable thickness measured in its axial direction.

Bei einer Ausführungsform der Erfindung ist das Rad mit einem im Inneren der Schlingen angeordneten, mit dem Förderband in Antriebsverbindung stehenden Reibrad gekoppelt. Vorzugsweise liegt die Berührungszone zwischem dem Rad und dem Reibrad etwa in der durch die Schlingen definierten Fläche. Es findet dabei also kein Durchdrücken der einzelnen Schlingen im Bereich der Berührungszonen statt, wodurch eine Dehnung der einzelnen Schlingen bewirkt werden könnte. Eine derartige Dehnung muß jedoch nicht unbedingt zu einer Beschädigung des Garns oder zu einer Beeinträchtigung eines Behandlungsvorganges führen, der mit Hilfe der erfindungsgemäßen Vorrichtung ausgeführt wird, beispielsweise eines Schrumpfvorganges oder eines Dämpfvorganges.In one embodiment of the invention the wheel is coupled to a friction wheel arranged in the interior of the loops and in driving connection with the conveyor belt. The contact zone between the wheel and the friction wheel is preferably approximately in the area defined by the loops. There is therefore no pushing through of the individual loops in the area of the contact zones, which could cause the individual loops to stretch. However, such an expansion does not necessarily have to lead to damage to the yarn or to an impairment of a treatment process which is carried out with the aid of the device according to the invention, for example a shrinking process or a steaming process.

Bei einer anderen Ausführungsform der Erfindung ist das Rad mit dem Förderband in Kontakt und das Förderband ist an seiner dem Rad abgewandten Seite in dessen Bereich abgestützt. Dadurch kann durch das Rad eine ausreichend starke Anpreßkraft gegen das Förderband ausgeübt werden, um dieses mittels Reibungskräften sicher anzutreiben. Die Umfangsgeschwindigkeit des Rads ist hierbei bis auf einen Schlupf gleich der Transportgeschwindigkeit des Förderbandes, so daß die Lage der sich zwischen dem Rad und dem Förderband befindenden Garnschlingen nicht oder kaum verändert wird. Die eeinzige Beeinflussung, die auf das Garn ausgeübt wird, ist ein kurzzeitiges Einklemmen zwischen dem Förderband und dem Rad (oder dem Reibrad und dem Rad bei der oben beschriebenen Ausführungsform), dieses kurzzeitige Zusammendrücken beeinflußt aber das Garn nicht oder nur in einem völlig vernachlässigbaren Umfang.In another embodiment of the invention, the wheel is in contact with the conveyor belt and the conveyor belt is supported on its side facing away from the wheel in its area. As a result, the wheel can exert a sufficiently strong contact pressure against the conveyor belt in order to drive it securely by means of frictional forces. The peripheral speed of the wheel is the same as the transport speed of the conveyor belt except for one slip, so that the position of the loops of yarn between the wheel and the conveyor belt is not or hardly changed. The only interference that is exerted on the yarn is a brief pinch between the conveyor belt and the wheel (or the friction wheel and the wheel in the embodiment described above), but this brief compression does not affect the yarn or only to a completely negligible extent .

Bei einer Vorrichtung, bei der der Bandförderer um seine Längsachse drehbar gelagert ist und eine im Bereich der Schlingen von außen angreifende Abstützung zum Verhindern einer Drehung des Bandförderers um seine Längsachse vorgesehen ist, die mindestens ein Stützrad aufweist, dessen Drehachse quer zur Förderrichtung des Bandförderers verläuft, wie dies von der bekannten Vorrichtung und aus der DE-B-2 338 703 bekannt ist, ist gemäß einer Ausführungsform der Erfindung vorgesehen, daß das rotierend antreibbare Rad gleichzeitig das Stützrad bildet. Das rotierend antreibbare Rad kann sich dabei an beliebiger Stelle innerhalb der Längenerstreckung des Bandförderers befinden. Das gleichzeitig als Stützrad dienende rotierend antreibbare Rad kann auch mindestens teilweise das Gewicht des Bandförderers tragen. Dabei kann das Antriebsrad zweckmäßigerweise als Antriebswalze ausgebildet sein und sich im Bereich des in Förderrichtung hinteren Endes des Bandförderers befinden.In a device in which the belt conveyor is rotatably mounted about its longitudinal axis and a support is provided in the area of the loops to prevent rotation of the belt conveyor about its longitudinal axis, said support having at least one support wheel, the axis of rotation of which runs transversely to the conveying direction of the belt conveyor As is known from the known device and from DE-B-2 338 703, it is provided according to one embodiment of the invention that the rotatably drivable wheel simultaneously forms the support wheel. The rotating drivable wheel can be located anywhere within the length of the belt conveyor. The rotating drivable wheel, which also serves as a support wheel, can also at least partially bear the weight of the belt conveyor. The drive wheel can expediently be designed as a drive roller and be located in the region of the rear end of the belt conveyor in the conveying direction.

Erfindungsgemäß kann die beschriebene Vorrichtung besonders vorteilhaft bei einer Texturiereinrichtung für Garn verwendet werden, bei der das Garn zunächst einer Texturiereinrichtung zugeführt wird, insbesondere einem Lufttexturiergerät, und anschließend einer Temperaturbehandlung zur Fixierung zugeführt wird. Diese Temperaturbehandlung findet auf dem oben beschriebenen Gerät statt, das zu diesem Zweck von einem Gehäuse umgeben ist, um die gewünschte Temperatur im Bereich der Garnschlingen aufrechtzuerhalten. Der besondere Vorteil der Verwendung liegt darin, daß eine erhebliche Verweilzeit des Garns im Bereich der Temperaturbehandlung bei relativ geringer Baulänge der Vorrichtung erreicht werden kann, so daß ein sicheres Fixieren der Texturierung möglich ist.According to the invention, the device described can be used particularly advantageously in a texturing device for yarn, in which the yarn is first fed to a texturing device, in particular an air texturing device, and then to a temperature treatment for fixation. This temperature treatment takes place on the device described above, which is surrounded for this purpose by a housing in order to maintain the desired temperature in the region of the yarn loops. The particular advantage of the use is that a considerable dwell time of the yarn in the area of the heat treatment can be achieved with a relatively short overall length of the device, so that the texturing can be securely fixed.

Die Verwendung einer ähnlichen Vorrichtung zum Thermofixieren von Garn ist aus der DE-B-2 338 703 bekannt. Nachfolgend wird ein Ausführungsbeispiel der Erfindung anhand der Zeichnung beschrieben.The use of a similar device for heat setting yarn is known from DE-B-2 338 703. An exemplary embodiment of the invention is described below with reference to the drawing.

Die in Fig. 1 gezeigte Vorrichtung umfasst einen Wickelkopf 1, an den sich ein Bandförderer 2 anschliesst, der durch eine Behandlungszone 3 führt, die durch ein strichpunktiert angedeutetes, die Behandlungszone umschliessendes Gehäuse 4 begrenzt ist. An dem dem Wickelkopf 1 abgewandten freien Ende des Bandförderers 2 wird das vom Wickelkopf 1 aufgelegte Garn über einen Abzugsring 5 abgezogen. Durch zwei Lichtschranken 6, 7 und 8, 9 wird dafür gesorgt, dass das Ende der wendeladigen Wicklung des Garns auf dem Bandförderer 2 ständig im Bereich zwischen diesen Lichtschranken bleibt; die Abzugsgeschwindigkeit wird entsprechend geregelt, um dieses Ziel zu erreichen.The device shown in FIG. 1 comprises a winding head 1, to which a belt conveyor 2 connects, which leads through a treatment zone 3, which is delimited by a housing 4 indicated by dash-dotted lines and enclosing the treatment zone. At the free end of the belt conveyor 2 facing away from the winding head 1, the yarn placed on the winding head 1 is drawn off via a draw-off ring 5. Two light barriers 6, 7 and 8, 9 ensure that the end of the winding winding of the yarn on the belt conveyor 2 remains constantly in the area between these light barriers; the withdrawal speed is regulated accordingly in order to achieve this goal.

Der Wickelkopf 1 weist ein Auflegerohr 11 auf, das mittels eines in einem Lager 12 um eine waagrechte Achse drehbar gelageden Halterohrs 13 drehbar gehalten ist, wobei das linke Ende des Auflegerohrs 11 genau in der Drehachse liegt, und das rechte Ende aus der Drehachse herausgebogen und durch eine mit dem Halterohr 13 rotierende Haltescheibe 14 gehalten ist. Das in Fig. 1 nicht dargestellte Garn wird durch ein Einblasrohr 15 ins Auflegerohr 11 eingeblasen und von diesem bei seiner Drehbewegung auf den Bandförderer in Form von Schlingen aufgelegt, die wegen der gleichzeitigen Transportbewegung des Bandförderers die Form einer wendelartigen Wicklung annehmen. Der Bandförderer 2 weist einen waagrecht liegenden zentralen Mast 18 auf, der durch ein Rohr gebildet ist, dessen in Fig. 1 linkes Ende in der Haltescheibe 14 mittels eines Kugellagers 19 drehbar gelagert ist. Daher ist das linke Ende des Masts 18 über die Haltescheibe 14, das Halterohr 13, das Lager 12 und mit diesem verbundene Befestigungswinkel 20, 21 an einer ortsfesten Unterlage 22 abgestützt. Das Auflegerohr 11 wird in der angedeuteten Weise über einen Riementrieb 23, der die Drehbewegung einer Antriebswelle 24 auf ein mit dem Auflegerohr 11 verbundenes Rad 25 überträgt, angetrieben.The winding head 1 has a support tube 11 which is rotatably held by means of a support tube 13 which is rotatably mounted about a horizontal axis in a bearing 12, the left end of the support tube 11 being exactly in the axis of rotation, and the right end being bent out of the axis of rotation and is held by a holding disk 14 rotating with the holding tube 13. The yarn, not shown in Fig. 1, is blown into the support tube 11 through a blow-in tube 15 and from this, during its rotational movement, placed on the belt conveyor in the form of loops which take the form of a helical winding due to the simultaneous transport movement of the belt conveyor. The belt conveyor 2 has a horizontally lying central mast 18, which is formed by a tube, the left end in Fig. 1 is rotatably mounted in the holding disc 14 by means of a ball bearing 19. Therefore, the left end of the mast 18 is supported on a stationary base 22 by means of the holding disc 14, the holding tube 13, the bearing 12 and the fastening brackets 20, 21 connected thereto. The support tube 11 is driven in the manner indicated via a belt drive 23, which transmits the rotary movement of a drive shaft 24 to a wheel 25 connected to the support tube 11.

Der Bandförderer 2 weist zwei Förderbänder 30 und 30' auf, die in der Blickrichtung der Fig. 1 im Abstand hintereinander in gleicher Weise verlegt sind, daher genügt es, den Verlauf des Bandes 30 zu erläutern. Dieses verläuft von einer vorderen unteren Rolle 31 geringfügig ansteigend zu einer hinteren unteren Rolle 32, bei der es umgelenkt wird und oberhalb des soeben beschriebenen Bandabschnitts zurückläuft, um eine Rolle 33 um etwa 270° herumgeführt ist, die sich in Blickrichtung der Fig. 1 hinter der Ebene der Rolle 32 befindet. Von der Rolle 33 gelangt das Band nach oben zu einer wiederum in Blickrichtung der Fig. 1 etwas weiter hinten liegenden Rolle 34, von dieser aus leicht ansteigend nach vorn zu einer Rolle 35, die das Band etwa 180° umlenkt, von wo aus es leicht fallend zu einer hinteren oberen Rolle 36 gelangt, die oberhalb der Rolle 32 liegt und von dieser wieder zur hinteren unteren Rolle 31. Die Richtung des Bandlaufes verläuft von der Rolle 31 zur Rolle 32 und somit auch von der Rolle 35 zur Rolle 36. Der Verlauf des Bandes 30' ist der gleiche. Die sich von vorn, in Fig. 1 also von links, nach hinten bewegenden Abschnitte der Bänder liegen an den Kanten eines rechteckigen Prismas, und die auf diesen sich nach hinten bewegenden Bandteilen aufgewickelten Garnschlingen, die ausreichend straff aufgewickelt werden, damit sie nicht durchhängen, liegen somit in den Flächen des genannten, sich im Querschnitt geringfügig verjüngenden Prismas.The belt conveyor 2 has two conveyor belts 30 and 30 ', which are laid one behind the other in the same way in the viewing direction of FIG. 1, so it is sufficient to explain the course of the belt 30. This runs from a front lower roller 31 slightly rising to a rear lower roller 32, in which it is deflected and runs back above the belt section just described, is guided around a roller 33 by approximately 270 °, which is behind in the viewing direction of FIG. 1 the level of the roller 32 is located. From the roller 33, the belt moves upwards to a roller 34, which is again somewhat further back in the direction of view in FIG. 1, from which it rises slightly to the front to a roller 35 which deflects the belt approximately 180 °, from where it is easy descending to a rear upper roller 36, which lies above the roller 32 and from there again to the rear lower roller 31. The direction of the belt run runs from the roller 31 to the roller 32 and thus also from the roller 35 to the roller 36. The course of band 30 'is the same. The sections of the tapes moving backwards from the front, that is to say from the left in FIG. 1, lie on the edges of a rectangular prism, and the loops of yarn wound on these tape parts moving backwards, which are wound sufficiently tightly so that they do not sag. thus lie in the surfaces of the above-mentioned prism which tapers slightly in cross section.

Wie Fig. 2 zeigt, sind die Rolle 34 und die zum Band 30' gehörende entsprechende Rolle 34' an einem mit dem Mast 18 unmittelbar verbundenen Klotz 40 befestigt, der nach unten ragende Fortsätze 41 trägt, an denen die Rollen 33 und 33' drehbar befestigt sind. Mit der Rolle 33 ist ein Reibrad 45 gleichachsig und drehfest verbunden, das mit seinem Umfang an seiner Unterseite bis in die durch die beiden zwischen den unteren Rollen 31 und 32 verlaufenden Abschnitte der Bänder 30 und 30' verlaufende Ebene reicht. Von unten her drückt gegen dieses Reibrad 45 ein walzenförrniges Rad 50, das in der angedeuteten Weise ortsfest gelagert ist und über eine Riemenscheibe 51 antreibbar ist. Das Rad 50 ist in Richtung seiner Drehachse, die senkrecht zur Zeichenebene der Fig. 1 und somit waagrecht verläuft, so lang, dass es sowohl mit dem Reibrad 45 des Förderbandes 30, als auch mit dem spiegelbildlich zum Reibrad 45 angeordneten Reibrad 45' des Förderbandes 30' in Eingriff ist. Dadurch wird der mit seinem in Fig. 1 linken Ende in der Haltescheibe 14 an sich drehbar gelagerte Mast bzw. der mit diesem verbundene Bandförderer daran gehindert, sich um seine waagrechte Längsachse zu drehen. Die Reibräder 45 werden durch das Gewicht des Bandförderes 2, soweit dieses nicht von dem Lager 12 aufgenommen wird, gegen das Rad 50 gedrückt. Die Reibungskraft zwischen dem Rad 50 und den Reibrädern 45, 45' ist so gross, dass die Drehbewegung des Rads 50 die Reibräder 45, 45' und somit die Förderbänder 30, 30' in Bewegung versetzt. In der Berührungszone zwischen den Reibrädern 45, 45' befinden sich auch die unteren waagrechten Abschnitte der auf den Bandförderer gewickelten Garnschlingen, die jedoch deswegen, weil die Relativgeschwindigkeit zwischen dem Rad 50 und den Reibrädern 45 und 45' praktisch den Wert Null hat, nicht in ihrer Lage geändert werden. Diese Garnschlingen laufen zwischen dem Reibrad 45 und dem Rad 50 in Transportrichtung des Bandförderers hindurch. Der Durchmesser des Reibrads 45 ist annähernd so gross wie der der Rolle 33, so dass die Umfangsgeschwindigkeit des Rads 50 der Transportgeschwindigkeit des Bandförderers entspricht.As shown in FIG. 2, the roller 34 and the corresponding roller 34 'belonging to the band 30' are fastened to a block 40 which is directly connected to the mast 18 and carries downward projecting extensions 41 on which the rollers 33 and 33 'are rotatable are attached. With the roller 33, a friction wheel 45 is connected coaxially and in a rotationally fixed manner, which extends with its circumference on its underside into the plane running through the two sections of the belts 30 and 30 'running between the lower rollers 31 and 32. A roller-shaped wheel 50 presses against this friction wheel 45 from below, which is mounted in a fixed manner in the manner indicated and can be driven via a pulley 51. The wheel 50 is so long in the direction of its axis of rotation, which runs perpendicular to the plane of the drawing in FIG. 1 and thus horizontally, that it is both with the friction wheel 45 of the conveyor belt 30 and with the friction wheel 45 'of the conveyor belt arranged in mirror image with the friction wheel 45 30 'is engaged. As a result, the mast which is rotatably mounted with its left end in FIG. 1 in the holding disc 14 or the belt conveyor connected to it is prevented from rotating about its horizontal longitudinal axis. The friction wheels 45 are pressed against the wheel 50 by the weight of the belt conveyor 2, insofar as this is not received by the bearing 12. The frictional force between the wheel 50 and the friction wheels 45, 45 'is so great that the rotational movement of the wheel 50 sets the friction wheels 45, 45' and thus the conveyor belts 30, 30 'in motion. In the contact zone between the friction wheels 45, 45 'are also the lower horizontal sections of the loops of thread wound on the belt conveyor, which, however, because the relative speed between the wheel 50 and the friction wheels 45 and 45' is practically zero, is not in their location will be changed. These loops of thread run between the friction wheel 45 and the wheel 50 in the transport direction of the belt conveyor. The diameter of the friction wheel 45 is approximately as large as that of the roller 33, so that the peripheral speed of the wheel 50 corresponds to the transport speed of the belt conveyor.

Da der Mast auch an seinem in Fig. 1 rechten Endbereich durch das Rad 50 unterstützt ist, braucht er im Gegensatz zu bekannten Geräten nicht freitragend ausgebildet zu sein und kann daher sehr einfach und mit geringem Gewicht hergestellt werden. Da durch die geschilderte Abstützung, die das Ende des Bandförderers frei lässt, wird es auch ermöglicht, das Garn mittels eines einfachen Abzugsrings 5 abzuziehen.Since the mast is also supported by the wheel 50 at its end region on the right in FIG. 1, in contrast to known devices, it does not have to be self-supporting and can therefore be manufactured very easily and with low weight. Since the described support, which leaves the end of the belt conveyor free, it is also possible to pull off the yarn by means of a simple pull-off ring 5.

In der in Fig. 1 angedeuteten Weise sind die hinteren Rollen 32 und 36 an zweiarmigen Hebeln 55 gelagert, so dass sie mittels einer auf das Ende des Masts 18 aufgeschraubten Verstellschraube 56 nach aussen oder innen (in Fig. 1 ist dies etwa in Richtung senkrecht nach oben oder unten) geschwenkt werden können, um hierdurch die Förderbänder zu spannen oder die von der Horizontalen geringfügig abweichenden Richtungen der Förderbänder zwischen den Rollen 31 und 32 bzw. 35 und 36 einzustellen.In the manner indicated in FIG. 1, the rear rollers 32 and 36 are mounted on two-armed levers 55, so that they can be adjusted inwards or outwards by means of an adjusting screw 56 screwed onto the end of the mast 18 (in FIG. 1, this is approximately perpendicular in the direction) can be pivoted up or down) in order to thereby tension the conveyor belts or to adjust the directions of the conveyor belts between the rollers 31 and 32 or 35 and 36 which deviate slightly from the horizontal.

In Fig. 4 ist die oben beschriebene Vorrichtung Bestandteil einer Texturiermaschine. Das Garn 60 läuft von einer Vorlagespule 61, die in einem Gatter 62 mit zahlreichen Vorlagespulen gelagert ist, über mehrere Fadenführungen 63, 64, 65 zu einem Lieferwerk 66, von wo es zur Texturierdüse 67 gelangt. Diese Düse ist in einem Gehäuse enthalten, das in Fig. 4 sichtbar ist. Nach der Texturierdüse gelangt das Garn über ein Lieferwerk 68 zum Einblasrohr 15 des anhand der Figuren 1 und 3 beschriebenen Garnspeichers, der Bestandteil einer Fixierkammer ist, in der das texturierte Garn fixiert wird. In Fig.4 sind die einzelnen Garnschlingen auf dem Bandförderer angedeutet. Das Garn wird am Ende des Bandförderers über den starren Abzugsring 5 abgezogen und läuft über Bandführungen 71, 72, 73 und 74 zu einer Aufspulvorrichtung 75.4, the device described above is part of a texturing machine. The yarn 60 runs from a supply spool 61, which is stored in a creel 62 with numerous supply spools, via a plurality of thread guides 63, 64, 65 to a delivery unit 66, from where it arrives at the texturing nozzle 67. This nozzle is contained in a housing that is visible in FIG. 4. After the texturing nozzle, the yarn arrives via a delivery mechanism 68 to the blow-in tube 15 of the yarn store described with reference to FIGS. 1 and 3, which is part of a fixing chamber in which the textured yarn is fixed. The individual yarn loops on the belt conveyor are indicated in FIG. The yarn is drawn off at the end of the belt conveyor via the rigid take-off ring 5 and runs over belt guides 71, 72, 73 and 74 to a winding device 75.

Die in Fig. 4 sichtbaren weiteren Lieferwerke und Aufspulvorrichtungen sowie Vorlagespulen stehen mit weiteren, hinter der gezeigten Fixierkammer angeordneten und nicht eigens dargestellten Fixierkammern in Verbindung. Der Garnspeicher mit dem Bandförderer 2 und dem Gehäuse 4 ist am oberen Ende eines Maschinengestells 78 befestigt, in dem die soeben genannten einzelnen Elemente der Texturiermaschine angeordnet sind. Der Garnspeicher lässt sich wegen seines geringen Gewichts ohne Schwierigkeiten an der gezeigten Stelle unterbringen, dabei bleibt zwischen den Vorlagespulen 61 und den beschriebenen Lieferwerken ein Bedienungsgang frei, der über einen Arbeitsgang 80, unterhalb von dem zwischen den Umlenkungen 72 und 73 das Garn hindurchläuft, begangen werden kann. Die Welle 24 und das Rad 50 werden über einen Riemen 76A bzw. 76B von je einem Antriebsmotor 77A bzw. 77B angetrieben, die auf je einem Podest 79A bzw. 79B stehen. Die Aufwickelvorrichtung 75 ist zum Wickeln einer Konusspule ausgebildet.The further delivery mechanisms and winding devices as well as supply spools visible in FIG. 4 are connected to further fixing chambers which are arranged behind the shown fixing chamber and are not specifically shown. The yarn store with the belt conveyor 2 and the housing 4 is fastened to the upper end of a machine frame 78, in which the individual elements of the texturing machine just mentioned are arranged. Because of its low weight, the yarn store can be accommodated without difficulty at the point shown, an operating aisle being left between the supply spools 61 and the described delivery mechanisms, which is carried out via an operation 80, below which the yarn passes between the deflections 72 and 73 can be. The shaft 24 and the wheel 50 are driven by a belt 76A or 76B by a drive motor 77A or 77B, each of which is on a platform 79A or 79B. The winding device 75 is designed for winding a cone coil.

Bei einer Länge des Gehäuses 4 von 0,5 m und der Länge einer Schlinge von 0,5 m sowie einem Legeabstand der einzelnen Garnschlingen von 0,3 mm ergibt sich eine Verweilzeit von etwa 2 Minuten für das Garn im Gehäuse 4 des Gamspeichers, wenn man eine Garngeschwindigkeit von 400 m/min annimmt.With a length of the housing 4 of 0.5 m and the length of a loop of 0.5 m and a spacing of the individual yarn loops of 0.3 mm, there is a dwell time of about 2 minutes for the yarn in the housing 4 of the thread memory, if a yarn speed of 400 m / min is assumed.

Die beschriebene Vorrichtung eignet sich besonders zum Bearbeiten von einem derartigen Garn, das einen Kletteneffekt zeigt, also an Abschnitten des gleichen Garns mehr oder weniger stark haftet. Die Vorrichtung kann so betrieben werden, dass auf der Fördervorrichtung die einzelnen Gamschlingen sich nicht berühren, so dass eine Störung des Betriebs durch den genannten Kletteneffekt nicht erfolgen kann. Unter dem Ausdruck Bandförderer soll auch eine Vorrichtung verstanden werden, bei der anstatt eines Förderbandes ein Seil oder ein seilartiges Fördermittel vorgesehen ist.The device described is particularly suitable for processing a yarn of this type which has a burdock effect, that is to say adheres more or less strongly to sections of the same yarn. The device can be operated in such a way that the individual thread loops do not touch each other on the conveying device, so that operation cannot be disrupted by the above-mentioned burdock effect. The term belt conveyor is also to be understood to mean a device in which a rope or a rope-like conveying means is provided instead of a conveyor belt.
