A retainer (9) prevents the plate (3) from moving through the spring action to hold the plate over its whole movement path within the can body (2). The retainer (9) is fitted to the plate (3), and pref. at its under side, with at least one setting unit (15) to block the plate (3) movement through the action of its spring (4).

Description

Die Erfindung betrifft eine Spinnkanne zum geordneten Ablegen von Faserband, mit einem oben offenen Kannenkörper, einem unter der Gewichtskraft des abgelegten Faserbandes vertikal innerhalb des Kannenkörpers beweglichen und von unten her mit der Druckkraft mindestens einer Feder beaufschlagten Federteller sowie mit Rückhaltemitteln für den Federteller.The invention relates to a sliver can for storing sliver in an orderly manner, with a can body open at the top, a spring plate which can move vertically within the can body under the weight of the sliver and which is acted upon from below with the pressure force of at least one spring, and with retaining means for the spring plate.

Spinnkannen werden dazu eingesetzt, Spinngut aufzunehmen, welches aus einem vliesartigen Band aus gestreckten und parallelisierten Fasern besteht. Die Einfüllung des Faserbandes in die Spinnkanne erfolgt, indem das aus dem Ausgang eines Kannenstockes austretende Faserband kreisförmig hin- und herbewegt und hierdurch in den um seine Achse angetriebenen Kannenkörper eingefüllt wird. Hierbei bilden sich Schlingen, die übereinander auf den durch eine Druckfeder von unten belasteten Federteller der Spinnkanne abgelegt werden. Unter der Einwirkung des Gewichtes des so abgelegten Spinngutes bewegt sich der Federteller entgegen der Kraft der Feder allmählich nach unten, wobei durch Wahl einer Feder mit geeigneter Federkennung das Niveau des Spinnguts innerhalb des Kannenkörpers unabhängig von der Füllmenge erhalten bleibt. Die Kanne ist gefüllt, wenn der Federteller am Boden des Kannenkörpers anschlägt, wobei die Feder auf ihre kleinste Abmessung zusammengedrückt ist. Um den genannten Niveauausgleich sicherzustellen, muß die Druckkraft der Feder etwas geringer sein als die Gewichtskraft der abgelegten Faserbandsäule. Ist die Kraft der Feder hingegen zu groß bemessen, führt dies, nachdem der Ablegedruck des Kannenstockes erst einmal entfällt, zu einem unerwünschten Herausschieben von Teilen des Faserbandmaterials aus der oben offenen Spinnkanne.Spinning cans are used to take up spinning material, which consists of a fleece-like band of stretched and parallelized fibers. The sliver is filled into the sliver can by circularly moving the sliver emerging from the outlet of a can stick and thereby filling it into the can body driven about its axis. This creates loops that are placed one above the other on the spring plate of the spinning can, which is loaded by a compression spring. Under the action of the weight of the spun material deposited in this way, the spring plate gradually moves downward against the force of the spring, the level of the spinning material within the can body being retained regardless of the filling quantity by selecting a spring with a suitable spring identification. The can is filled when the spring plate strikes the bottom of the can body, the spring being compressed to its smallest dimension. In order to ensure the level compensation mentioned, the pressure force of the spring must be slightly less than the weight force of the sliver sliver. If, on the other hand, the force of the spring is too great, this leads to an undesired pushing out of parts of the sliver material from the open-top spinning can after the pressure of the can stick has been removed.

Zur Erhöhung der Kannenfüllmenge ist es grundsätzlich anzustreben, den von unten auf den Federteller ausgeübten Druck der Feder zu erhöhen, da hierdurch im Gegenzuge ein erhöhter Ablegedruck erforderlich ist, der zu einem erhöhten Anpreßdruck des neu eingefüllten Faserbandes und damit zu einem insgesamt besseren Füllgrad führt. Diesem Bestreben sind jedoch die oben bereits genannten Grenzen gesetzt. Wird die Druckkraft der Feder zu groß bemessen, führt dies nach vollständiger Füllung der Spinnkanne und nach deren Entfernen aus dem Kannenstock dazu, daß zumindest Teile des bereits abgelegten Faserbandes pilzförmig aus der Spinnkanne emporquellen, was beim anschließenden Weitertransport der gefüllten Spinnkanne erhebliche Schwierigkeiten bereiten kann.In order to increase the can filling quantity, it is fundamentally desirable to increase the pressure of the spring exerted on the spring plate from below, since this in turn requires an increased deposit pressure, which leads to an increased contact pressure of the newly filled sliver and thus to an overall better filling level. However, this endeavor is subject to the limits already mentioned above. If the pressure force of the spring is too large, this results in the spinning can being completely filled and after it has been removed from the can stock, causing at least parts of the sliver that has already been deposited to mushroom out of the spinning can, which can cause considerable difficulties in the subsequent transportation of the filled spinning can.

In der EP 0 255 880 A1 ist daher bereits vorgeschlagen worden, an der Unterseite des Federtellers eine starre Rastvorrichtung zu befestigen, die in der untersten Stellung des Federtellers diesen am Boden der Spinnkanne verriegelt. Auf diese Weise wird der Federteller beim Transport der gefüllten Spinnkanne und beim Einführen in eine nachfolgende Maschine in der untersten Stellung festgehalten, und das abgelegte Faserband kann selbst bei Verwendung einer kräftigen Feder nicht nach oben aus dem Kannenkörper herausgedrückt werden. Nachteilig bei der Spinnkanne gemäß EP 0 255 880 A1 ist, daß die darin beschriebenen Rückhaltemittel in Gestalt der Verriegelung erst und nur dann wirksam werden, nachdem der Federteller seine unterste Stellung innerhalb des Kannenkörpers erreicht hat.It has therefore already been proposed in EP 0 255 880 A1 to attach a rigid latching device to the underside of the spring plate, which, in the lowest position of the spring plate, locks the spring plate to the bottom of the spinning can. In this way, the spring plate is held in the lowest position during transport of the filled spinning can and when it is inserted into a subsequent machine, and the sliver that is laid down cannot be pushed up out of the can body even when a strong spring is used. A disadvantage of the spinning can according to EP 0 255 880 A1 is that the retaining means described therein only take effect in the form of the lock and only after the spring plate has reached its lowest position within the can body.

Eine Spinnkanne mit den eingangs genannten Merkmalen ist aus der DE-OS 27 12 982 bekannt. Mit dem Ziel, eine dichtere, gepreßtere Füllung der Faserbandkanne zu ermöglichen, wird in dieser Druckschrift vorgeschlagen, die Unterseite des Federtellers zusätzlich zu der normalen Spiralfeder durch eine Zusatzfeder zu belasten, die sich mit ihrem dem Federteller abgewandten, unteren Ende auf einer Platte abstützt, die höhenveränderlich in dem Kannenkörper geführt ist. Die Platte ist mit Klemmelementen versehen, die die Platte in jeder beliebigen Höhenlage innerhalb des Kannenkörpers arretieren können. Bei dieser Spinnkanne unterliegt der Federteller in jeder Höhenlage ausschließlich den summierten Federkräften der beiden Federn. Hierbei ist zwar die Zusatzfeder mitwandernd in dem Sinne, daß ihr unteres Ende je nach Klemmzustand eine unterschiedliche Höhe innerhalb der Kanne aufweist. Gleichwohl unterliegt der Federteller stets der von unten einwirkenden Kraftwirkung dieser Zusatzfeder. Wird daher bei dieser Spinnkanne der von oben auf das abgelegte Faserband einwirkende Druck entlastet, können noch einige Lagen des Faserbandes in unerwünschter Weise wieder aus der Kanne herausquellen.A spinning can with the features mentioned above is known from DE-OS 27 12 982. With the aim of enabling a denser, more compressed filling of the sliver can, this publication proposes loading the underside of the spring plate in addition to the normal spiral spring by an additional spring which is supported on a plate with its lower end facing away from the spring plate. which is adjustable in height in the can body. The plate is provided with clamping elements that can lock the plate at any height within the can body. With this spinning can, the spring plate is subject to the summed spring forces of the two springs at any height. Here, the additional spring migrates in the sense that its lower end has a different height within the can depending on the clamped state. Nevertheless the spring plate is always subject to the force of this additional spring acting from below. If the pressure acting on the deposited sliver from above is relieved in this spinning can, some layers of the sliver can still undesirably swell out of the can.

Der Erfindung liegt daher die Aufgabe zugrunde, bei einer Spinnkanne zum geordneten Ablegen von Faserband mit einfachen Mitteln eine Erhöhung des Kannenfüllgrades zu erreichen, ohne daß es zu einem unerwünschten Herausdrücken des bereits abgelegten Faserbandes kommen kann.The invention is therefore based on the object at a spinning pot for orderly depositing sliver with simple means to achieve an increase in the Kannenfüllgrades, without being able to come to an undesirable pushing out the already deposited sliver.

Zur Lösung wird bei einer Spinnkanne der eingangs genannten Art vorgeschlagen, daß die Rückhaltemittel eine federkraftbedingte Rückkehrbewegung des Federtellers verhindern, daß die Rückhaltemittel über den gesamten Weg wirksam sind, den der Federteller innerhalb des Kannenkörpers zurücklegen kann, und daß die Rückhaltemittel an dem Federteller und vorzugsweise dessen Unterseite befestigt und mit mindestens einem Feststeller versehen sind, der den Federteller entgegen der Druckkraft der Feder blockiert.To solve this problem , it is proposed in a spinning can of the type mentioned at the outset that the retaining means prevent a return movement of the spring plate caused by spring force, that the retaining means are effective over the entire distance that the spring plate can travel within the can body, and that the retaining means on the spring plate and preferably the underside of which is attached and provided with at least one locking device which blocks the spring plate against the pressure force of the spring.

Durch diese Maßnahmen besteht auch bei Verwendung einer stärker dimensionierten Feder keine Gefahr, daß bereits abgelegtes Faserbandmaterial wieder nach oben aus der Spinnkanne herausgedrückt wird. Hierzu sind Rückhaltemittel vorgesehen, die über den gesamten Weg des Federtellers wirksam und mit mindestens einem Feststeller versehen sind, der den Federteller entgegen der Druckkraft der Feder blockiert. Hierdurch wird die Möglichkeit geschaffen, unter Verwendung einer kräftigeren Feder mit einem größeren Ablegedruck beim Befüllen der Spinnkanne zu arbeiten, wodurch sich ein verbesserter Kannenfüllgrad mit dichterer Packung des Faserbandes ergibt. Dieser Vorteil stellt sich unabhängig von der Gesamtfüllmenge ein, da die Rückhaltemittel sowohl bei vollständig gefüllter als auch bei nur teilweise gefüllter Spinnkanne wirksam sind.With these measures, even when using a larger spring, there is no danger that fiber sliver material that has already been deposited will be pushed upwards out of the spinning can again. For this purpose, retaining means are provided which are effective over the entire path of the spring plate and are provided with at least one locking device which blocks the spring plate against the pressure force of the spring. This creates the possibility of using a stronger spring with a larger depositing pressure when filling the sliver can, which results in an improved can filling degree with denser packing of the sliver. This advantage arises regardless of the total filling quantity, since the retention means are effective both when the spinning can is fully filled and when it is only partially filled.

Von weiterem Vorteil ist, daß die Rückhaltemittel unabhängig von der Ablegegeschwindigkeit des Faserbandes sowie auch unabhängig von den Materialeigenschaften des Faserbandes arbeiten. Für die Funktion der Rückhaltemittel spielt es daher keine Rolle, ob die Befüllung der Spinnkanne z. B. mittels eines Kannenstockes mit hoher oder geringer Geschwindigkeit erfolgt. Ebensowenig spielt es eine Rolle, welche Dicke und Kompressibilität das abgelegte Faserband aufweist.It is a further advantage that the retention means work independently of the speed at which the sliver is laid down and also independently of the material properties of the sliver. For the function of the retention means, it is therefore irrelevant whether the filling of the spinning can, for. B. takes place by means of a jug at high or low speed. Just as little it matters what thickness and compressibility the sliver has.

Die Rückhaltemittel bestehen vorzugsweise aus einem flexiblen und nicht dehnbaren Zugelement zwischen Federteller und Abschlußboden des Kannenkörpers.The restraint means preferably consist of a flexible and non-stretchable tension element between the spring plate and the bottom of the can body.

Gemäß einer ersten bevorzugten Ausführungsform handelt es sich bei dem Zugelement um eine Rollfeder. Derartige Rollfedern haben die Eigenschaft, sich infolge einer vorgeprägten Biegespannung von selbst aufzuwickeln. Der Vorteil der Rollfeder besteht darin, daß diese mit ihrem eingerollten Ende im Bereich des Abschlußbodens des Kannenkörpers angeordnet werden kann, wo sie relativ wenig Platz benötigt, so daß der vertikale Bewegungsweg des Federtellers innerhalb des Kannenkörpers nicht eingeschränkt wird. Gemäß einer Ausgestaltung ist daher vorgesehen, daß die Rollfeder mit ihrem eingerollten Ende im Bereich des Abschlußbodens innerhalb oder außerhalb der Kanne gelagert ist, und daß das freie, gestreckte Ende der Rollfeder an der Unterseite des Federtellers befestigt ist.According to a first preferred embodiment, the tension element is a roller spring. Such coiled springs have the property of winding themselves up as a result of a pre-embossed bending tension. The advantage of the roller spring is that it can be arranged with its rolled-up end in the area of the bottom of the can body, where it requires relatively little space, so that the vertical movement path of the spring plate within the can body is not restricted. According to one embodiment, it is therefore provided that the rolled-up spring is mounted with its rolled-up end in the region of the end plate inside or outside the can, and that the free, stretched end of the rolled spring is attached to the underside of the spring plate.

Gemäß einer zweiten Ausführungsvariante setzen sich die Rückhaltemittel aus einem flexiblen und nicht dehnbaren Zugelement zwischen Federteller und Abschlußboden des Kannenkörpers sowie einer durch den Feststeller blockierbaren Wickelrolle für das Zugelement zusammen. Auch die Wickelrolle kann im Bereich unterhalb oder oberhalb des Abschlußbodens des Kannenkörpers angeordnet werden, wo sie relativ wenig Platz benötigt.According to a second embodiment variant, the retaining means are composed of a flexible and non-stretchable tension element between the spring plate and the end base of the can body and a winding roller for the tension element which can be blocked by the arrester. The winding roll can also be arranged in the area below or above the end bottom of the can body, where it requires relatively little space.

Sowohl bei Verwendung der Rollfeder als auch bei Verwendung des Seiles mit Wickelrolle ist eine stufenlose Arbeitsweise des Rückhaltemittels möglich, so daß der Federteller in jeder beliebigen Höhenlage durch den Feststeller gegen eine Bewegung nach oben blockiert wird. Hierbei bleibt das Zugelement straff, da im Falle der Verwendung der Rollfeder diese das Bestreben hat, sich aufzurollen, wohingegen im Falle der Verwendung eines Seiles dieses durch die federbelastete Wickelrolle gespannt bleibt.Both when using the roller spring and when using the rope with winding roller, a stepless operation of the retaining means is possible, so that the spring plate is blocked at any height by the lock against an upward movement. In this case, the tension element remains taut, since if the roller spring is used, it tends to roll up, whereas if a rope is used, it remains tensioned by the spring-loaded winding roller.

Mit der Erfindung wird schließlich ein Löseelement für den Feststeller vorgeschlagen, wobei das Löseelement vorzugsweise aus der Unterseite des Kannenkörpers herausragt.Finally, the invention proposes a release element for the arrester, the release element preferably protruding from the underside of the can body.

Die in Fig. 1 dargestellte Spinnkanne setzt sich aus einem unten mit einem Abschlußboden 1 versehenen und nach oben hin offenen Kannenkörper 2, einem in dem Kannenkörper 2 angeordneten Federteller 3 und einer Feder 4 zusammen, die, am Abschlußboden 1 anliegend, sich von unten gegen den Federteller 3 stützt. Beim Ausführungsbeispiel ist eine einzige Feder 4 in Gestalt einer Schraubenfeder vorhanden. Alternativ können auch mehrere Federn vorhanden sein, wobei darauf zu achten ist, daß der Federteller 3 im wesentlichen waagerecht abgestützt wird.The spinning can shown in FIG. 1 is composed of a can body 2 provided at the bottom with a bottom 1 and open at the top, a spring plate 3 arranged in the can body 2 and a spring 4 which, resting on the bottom 1, oppose one another from below supports the spring plate 3. In the exemplary embodiment there is a single spring 4 in the form of a helical spring. Alternatively, several springs can also be present, care being taken that the spring plate 3 is supported essentially horizontally.

Der Federteller 3 ist entlang der Innenwand 5 des Kannenkörpers 2 mit geringem Spiel geführt. Beim Ausführungsbeispiel ist der Kannenkörper 2 zylindrisch gestaltet, so daß der Federteller 3 die Form einer runden Platte aufweist. Rollen 6 an der Unterseite der Spinnkanne erleichtern deren Transport.The spring plate 3 is guided along the inner wall 5 of the can body 2 with little play. In the exemplary embodiment, the can body 2 is cylindrical designed so that the spring plate 3 has the shape of a round plate. Rollers 6 on the underside of the spinning can facilitate their transport.

Die Spinnkanne dient dazu, in Schleifen abgelegtes Faserband aufzunehmen. In Fig. 2 ist die Spinnkanne in vollständig mit Faserband 7 gefülltem Zustand dargestellt. Der Federteller 3 hat sich bis in seine tiefste Stellung nahe des Abschlußbodens 1 abgesenkt. Die Feder 4 ist hierbei maximal gestaucht.The spinning can is used to hold sliver deposited in loops. 2 shows the spinning can in the state completely filled with sliver 7. The spring plate 3 has lowered into its lowest position near the bottom plate 1. The spring 4 is compressed to the maximum.

Fig. 2 läßt eine grundsätzliche Problematik bei Spinnkannen erkennen: Die Kennlinie der Feder 4 muß bei herkömmlich aufgebauten Spinnkannen exakt auf das darin abzulegende Faserband abgestimmt sein. Unabhängig von der Höhenlage des Federtellers 3 muß die von der Feder ausgeübte Druckkraft stets so groß sein, daß die auf dem Federteller ruhende Faserbandsäule nicht oder, wie in Fig. 2 dargestellt, nur mit einer bestimmten Höhe über den oberen Rand 8 des Kannenkörpers 2 hinausragt. Ist die Druckkraft der Feder zu gering, so verschwindet die gesamte Faserbandsäule innerhalb des Kannenkörpers, so daß neues Faserband nicht mit dem hierzu erforderlichen Druck abgelegt werden kann. Ist andererseits die Druckkraft der Feder zu stark bemessen, tendiert diese dazu, unerwünscht viel Faserbandmaterial wieder nach oben aus dem Kannenkörper herauszuquellen. Aufgrund der zuletzt geschilderten Zusammenhänge ist es nicht ohne weiteres möglich, die Kennlinie der Feder 4 und damit die von dieser ausgeübte Druckkraft zu steigern.Fig. 2 shows a basic problem with spinning cans: The characteristic of the spring 4 must be matched exactly to the sliver to be stored in conventionally constructed spinning cans. Regardless of the height of the spring plate 3, the pressure force exerted by the spring must always be so great that the fiber band column resting on the spring plate does not protrude, or, as shown in FIG. 2, only by a certain height above the upper edge 8 of the can body 2 . If the pressure force of the spring is too low, the entire fiber sliver column disappears within the can body, so that new fiber sliver cannot be deposited with the pressure required for this. On the other hand, if the pressure force of the spring is too large, it tends to cause an undesirable amount of sliver material to swell out of the can body again. Because of the relationships described last, it is not readily possible to increase the characteristic of the spring 4 and thus the pressure force exerted by it.

Mit der Erfindung hingegen ist es sehr wohl möglich, eine deutlich stärkere Feder 4 als bei herkömmlichen Spinnkannen einzusetzen. Um jedoch zugleich die geschilderten Nachteile zu vermeiden, werden Maßnahmen ergriffen, mit deren Hilfe der Federteller 3 an einem Anheben gehindert wird. Zu diesem Zweck sind unterhalb des Federtellers 3 auf Zug belastete Rückhaltemittel 9 angeordnet, die unabhängig von der Höhenlage des Federtellers 3 diesen daran hindern, sich infolge der Druckeinwirkung der Feder 4 aus einer einmal eingenommenen Stellung wieder nach oben zu bewegen. Diese Rückhaltemittel 9 sind "nachführbar", d.h. sie passen sich der Abwärtsbewegung des Federtellers 3 während des Einfüllens von Faserband 7 an, sperren jedoch den Federteller 3 in entgegengesetzte Richtung, d.h. gegen eine Bewegung nach oben.With the invention, however, it is very possible to use a much stronger spring 4 than in conventional spinning cans. However, in order to avoid the disadvantages described, measures are taken to prevent the spring plate 3 from lifting. For this purpose, below the spring plate 3 loaded tensile restraining means 9 are arranged, which regardless of the height of the spring plate 3 prevent it from moving up again from a position once taken due to the pressure of the spring 4. These retaining means 9 are "trackable", ie they adapt to the downward movement of the spring plate 3 during the filling of fiber sliver 7, but they lock the spring plate 3 in the opposite direction, ie against an upward movement.

Zu diesem Zweck bestehen die Rückhaltemittel 9 bei einer in den Figuren 3 und 4 dargestellten ersten Ausführungsform aus einem Zugelement 10 in Gestalt eines biegsamen Seiles, dessen nicht benötigte Länge von einer federgespannten Wickelrolle aufgenommen wird, die im Bereich des Abschlußbodens 1 gelagert ist. Das freie Ende des straff gespannten Zugelementes 10 ist, wie Fig. 1 erkennen läßt, an der Unterseite des Federtellers 3 in dessen Mitte befestigt.For this purpose, the retaining means 9 in a first embodiment shown in FIGS. 3 and 4 consist of a tension element 10 in the form of a flexible rope, the length of which is not required is taken up by a spring-loaded winding roller which is mounted in the area of the end floor 1. The free end of the taut tension element 10 is, as shown in FIG. 1, attached to the underside of the spring plate 3 in the middle.

In Fig. 3 sind Einzelheiten der im Bereich des Abschlußbodens angeordneten Wickelrolle 11 dargestellt. Die Wickelrolle 11 ist als langgestreckte Trommel ausgebildet, auf deren Umfang eine wendelförmige Nut 12 zur Aufnahme der Seilwindungen eingearbeitet ist. Die Wickelrolle 11 ist beidseitig in einem Gehäuse 13 gelagert, welches am Abschlußboden 1 der Spinnkanne befestigt ist. Um das Zugelement 10 zwischen Federteller 3 und Wickelrolle 11 gespannt zu halten, ist die Wickelrolle 11 mit einer im Sinne einer Aufwicklung des Zugelementes 10 vorgespannten Feder 14 versehen. Die Feder 14 ist als Schraubenfeder in einem mittigen Hohlraum 15 der Wickelrolle 11 angeordnet. Ihr eines Ende ist dabei gehäusefest angeordnet, während das andere Ende der Feder 14 mit der Wickelrolle 11 verbunden ist, und diese und damit auch das seilförmige Zugelement 10 spannt. Infolge der so erzeugten Rückstellkraft der Feder 14 wird das freie Ende des Zugelementes 10 während des Absenkens des Federtellers 3 stetig verkürzt, dabei jedoch jederzeit straff gehalten. Im Gegensatz zu dieser federgestützten Aufwickelbewegung ist eine Abwickelbewegung nicht möglich. Dies verhindert ein Feststeller 15, der eine Drehung der Wickelrolle 11 in Aufwickelrichtung zuläßt, jedoch in Abwickelrichtung sperrt bzw. blockiert. Beim Ausführungsbeispiel ist der Feststeller 15 ein Reibkeil, der die Wickelrolle 11 in die eine Richtung freigibt, und eine Bewegung in die andere Richtung durch Klemmen blockiert. Mittels eines Löseelementes 16, welches aus der Unterseite des Kannenkörpers 2 herausragt, läßt sich der Feststeller 15 lösen.3 shows details of the winding roll 11 arranged in the region of the end plate. The winding roll 11 is designed as an elongated drum, on the circumference of which a helical groove 12 is incorporated for receiving the cable turns. The winding roll 11 is mounted on both sides in a housing 13 which is attached to the bottom 1 of the spinning can. In order to keep the tension element 10 tensioned between the spring plate 3 and the winding roller 11, the winding roller 11 is provided with a spring 14 preloaded in the sense of a winding of the tension element 10. The spring 14 is arranged as a helical spring in a central cavity 15 of the winding roll 11. One end is fixed to the housing, while the other end of the spring 14 is connected to the winding roller 11, and this and thus also the cable-shaped tension element 10 tensions. As a result of the restoring force of the spring 14 generated in this way, the free end of the tension element 10 is continuously shortened while the spring plate 3 is being lowered, but is kept taut at all times. In contrast to this spring-assisted winding movement, an unwinding movement is not possible. This prevents a lock 15, which allows the winding roll 11 to rotate in the winding direction, but blocks or blocks it in the winding direction. In the exemplary embodiment, the arrester 15 is a friction wedge, which releases the winding roll 11 in one direction and blocks movement in the other direction by clamping. The detent 15 can be released by means of a release element 16 which protrudes from the underside of the can body 2.

Bei dem in den Figuren 3 und 4 dargestellten Ausführungsbeispiel ist die Wickelrolle 11 horizontal gelagert. Ebenso ist es jedoch möglich, eine Wickelrolle mit vertikaler Drehachse zu verwenden, wobei in diesem Fall das Zugelement 10 einmal um 90° umgelenkt, und zudem mehrlagig auf der Wickelrolle aufgewickelt wird.In the embodiment shown in Figures 3 and 4, the winding roll 11 is mounted horizontally. However, it is also possible to use a winding roll with a vertical axis of rotation, in which case the tension element 10 is deflected once by 90 ° and is also wound up in multiple layers on the winding roll.

Während des Ablegens von Faserband in der beschriebenen Spinnkanne senkt sich unter dem Einfluß des Gewichtes des Faserbandes sowie des Anpreßdruckes des Kannenstockes der Federteller 3 zunehmend ab. Hierbei sorgt die Rückstellkraft der Feder 14 der Wickelrolle 11 dafür, daß das Zugelement 10 stets gespannt bleibt. Sobald, etwa infolge der Herausnahme der Spinnkanne aus dem Kannenstock, der zusätzliche Anpreßdruck des Kannenstocks entfällt, werden die Rückhaltemittel 9 wirksam. Obwohl die Druckkraft der Feder 4 die Gewichtskraft des aufliegenden Faserbandes übersteigt, ist der Federteller 3 gegen eine Bewegung nach oben blockiert, so daß das Faserband nicht nach oben aus der Spinnkanne herausgedrückt werden kann. Erst durch Lösen des Feststellers 15 mittels des Löseelementes 16 wird die Wickelrolle freigegeben, so daß sich der Federteller 3 dann unter der Wirkung der Feder 4 nach oben bewegt. Diese Freigabe erfolgt i.d.R. dann, nachdem die Spinnkanne vollständig entleert worden ist.During the depositing of sliver in the spinning can described, the spring plate 3 decreases increasingly under the influence of the weight of the sliver and the contact pressure of the can stick. Here, the restoring force of the spring 14 of the winding roll 11 ensures that the tension element 10 always remains under tension. As soon as, for example as a result of the removal of the spinning can from the can stock, the additional contact pressure of the can stock is eliminated, the retaining means 9 become effective. Although the compressive force of the spring 4 exceeds the weight of the sliver lying thereon, the spring plate 3 is blocked against an upward movement, so that the sliver cannot be pushed up out of the spinning can. Only when the lock 15 is released by means of the release element 16 is the winding roller released, so that the spring plate 3 then moves upwards under the action of the spring 4. This release usually takes place then after the spinning can has been completely emptied.

Bei dem auf der Fig. 5 dargestellten zweiten Ausführungsbeispiel wird als Rückhaltemittel 9 bzw. Zugelement 10 lediglich eine Rollfeder 18 eingesetzt, deren aufgewickeltes Ende 19 sich in einer zylindrischen Kammer 20 befindet. Bei der Rollfeder 18 handelt es sich um einen schmalen Blechstreifen, der aufgrund der Materialstruktur das Bestreben hat, sich selbsttätig aufzuwickeln. Das freie Ende der Rollfeder 18 ist hierbei analog zu der ersten Ausführungsvariante an der Unterseite des Federtellers 3 befestigt. Da eine Rollfeder 18 infolge ihrer Eigenspannung zu einem selbsttätigen Aufrollen neigt, ist eine zusätzliche Feder entsprechend der Feder 14 bei der Ausführungsvariante gemäß den Figuren 3 und 4 nicht erforderlich.In the second exemplary embodiment shown in FIG. 5, only a roller spring 18 is used as the retaining means 9 or tension element 10, the wound end 19 of which is located in a cylindrical chamber 20. The roller spring 18 is a narrow sheet metal strip which, because of the material structure, tends to wind itself up automatically. The free end of the roller spring 18 is attached to the underside of the spring plate 3 analogously to the first embodiment. Since a roller spring 18 tends to roll up automatically due to its inherent tension, an additional spring corresponding to the spring 14 is not required in the embodiment variant according to FIGS. 3 and 4.

Als Feststeller 15 dient ein etwa viertelkreisförmig gestalteter Hebel, dessen eines Ende auf einer gehäusefesten Achse 21 gelagert ist, die sich parallel zur Wickelachse erstreckt. Die Rollfeder 18 legt sich um die viertelkreisförmige Außenkontur des Feststellers 15, wobei das freie, gestreckte Ende der Rollfeder 18 den Feststeller 15 an jenem Ende verläßt, welches dem Ende mit der Achse 21 abgewandt ist. An seinem auf der Achse 21 gelagerten Ende ist der viertelkreisförmige Feststeller 15 mit einer relativ kurzen Verlängerung 22 versehen, so daß der Feststeller 15 als Hebel betrachtet werden kann, dessen langer Hebelarm durch den Viertelkreis gebildet wird, und dessen kurzer Hebelarm aus der Verlängerung 22 besteht. Diese Verlängerung 22 bildet an ihrer äußeren Kante einen Klemmnocken 23a, der unter Krafteinwirkung durch den viertelkreisförmigen Hebel die Rollfeder 18 gegen eine reibungserhöhende Fläche 23b preßt. Der Spalt zwischen der Verlängerung 22 mit dem Klemmnocken 23a und der gegenüberliegenden reibungserhöhenden Fläche 23b ist so gering, daß die Rollfeder 18 gerade hindurch paßt.An approximately quarter-circle lever is used as the lock 15, one end of which is mounted on an axis 21 which is fixed to the housing and extends parallel to the winding axis. The roller spring 18 wraps around the quarter-circular outer contour of the arrester 15, the free, elongated end of the roller spring 18 leaving the arrester 15 at the end which faces away from the end with the axis 21. At its end mounted on the axis 21, the quarter-circle lock 15 is provided with a relatively short extension 22, so that the lock 15 can be regarded as a lever, the long lever arm of which is formed by the quarter circle, and the short lever arm of which consists of the extension 22 . This extension 22 forms on her outer edge a clamping cam 23a, which presses the roller spring 18 against a friction-increasing surface 23b under the action of the quarter-circular lever. The gap between the extension 22 with the clamping cam 23a and the opposite friction-increasing surface 23b is so small that the roller spring 18 fits straight through.

Sofern das freie Ende der Rollfeder 18 infolge der auf den Federteller 3 des Kannenkörpers 2 wirkenden Feder 4 zugbelastet ist, ist der verschwenkbare Feststeller 15 bestrebt, den Klemmnocken 23a gegen die reibungserhöhende Fläche 23b zu pressen, und auf diese Weise die Rollfeder 18 einzuklemmen. Wir hingegen die Zugkraft im freien Ende der Rollfeder 18 entlastet, so schwenkt der Feststeller 15 von dem aufgewickelten Ende 19 der Rollfeder 18 weg, wodurch sich der Spalt zwischen Klemmnocken 23a und reibungserhöhender Fläche 23b öffnet, und die Rollfeder 18 sich unter Materialeinzug weiter aufrollt, bis das freie Ende wieder straff gespannt ist.If the free end of the roller spring 18 is subjected to tensile stress as a result of the spring 4 acting on the spring plate 3 of the can body 2, the pivotable arrester 15 endeavors to press the clamping cam 23a against the friction-increasing surface 23b, and in this way to clamp the roller spring 18. If, on the other hand, the tensile force in the free end of the roller spring 18 is relieved, the arrester 15 swivels away from the wound end 19 of the roller spring 18, as a result of which the gap between the clamping cams 23a and the friction-increasing surface 23b opens, and the roller spring 18 continues to roll up while material is being drawn in, until the free end is tightened again.

Auch bei der Ausführungsform gemäß Fig. 5 ist ein Löseelement 16 vorgesehen, welches über einen Nocken 17 betätigt wird. Das Löseelement 16 schwenkt bei seiner Betätigung den Feststeller 15 von dem aufgewickelten Ende 19 der Rollfeder weg, so daß sich die Klemmung löst und sich die Rollfeder 18 unter dem Einfluß der großen Feder 4 abwickelt.A release element 16 is also provided in the embodiment according to FIG. 5, which is actuated via a cam 17. When released, the release element 16 pivots the locking device 15 away from the wound end 19 of the roller spring, so that the clamping is released and the roller spring 18 unwinds under the influence of the large spring 4.

Die Betätigung des Löseelementes 16 ist auch automatisch möglich. Zu diesem Zweck können im Boden Nocken 17 befestigt sein, die beim Hinüberfahren der Spinnkanne Druck auf das Löseelement 16 ausüben, und damit den Feststeller 15 entsperren.The actuation of the release element 16 is also possible automatically. For this purpose, cams 17 can be fastened in the bottom, which exert pressure on the release element 16 when the spinning can moves over, and thus unlock the arrester 15.

Die Kennlinie der Feder 4 ist vorzugsweise so ausgelegt, daß deren Druckkraft die Gewichtskraft des auf dem Federteller 3 aufliegenden Faserbandes um mindestens 10 % übersteigt. Hierdurch ist es möglich, neues Faserband mit relativ hohem Gegendruck in der Spinnkanne abzulegen, und damit den Füllgrad zu verbessern.The characteristic curve of the spring 4 is preferably designed such that its compressive force exceeds the weight of the sliver resting on the spring plate 3 by at least 10%. This makes it possible to deposit new sliver in the spinning can with a relatively high back pressure, and thus to improve the degree of filling.
