Description

Die Erfindung betrifft eine Vorrichtung zum Stapeln von Schlauchabschnitten für die Herstellung von Säcken, mit einer Transporteinrichtung, die die Schlauchabschnitte zu einer Stapelstation zuführt.The invention relates to a device for stacking hose sections for the production of bags, with a transport device that the Feeds hose sections to a stacking station.

Bei der Herstellung von Säcken aus Papier oder Folie wird häufig zunächst ein endloser Schlauch hergestellt, der dann in einzelne, jeweils einen Sack bildende Schlauchabschnitte aufgeteilt wird. Die einzelnen Schlauchabschnitte, die mit einer Transporteinrichtung kontinuierlich und aufeinanderfolgend transportiert werden, werden dann häufig zunächst in einem Stapel gesammelt, und erst in einem späteren Arbeitsgang werden dann die Enden der Schlauchabschnitte geschlossen und ggf. die Säcke mit Inhalt gefüllt.When manufacturing sacks from paper or foil, one is often first endless hose made, which then in individual, each forming a sack Hose sections is divided. The individual hose sections that with a transport device continuously and successively transported are then often first collected in a stack and only in the ends of the tube sections are then closed in a later operation and if necessary the sacks filled with content.

Für bestimmte Anwendungen werden Säcke benötigt, die mehrlagige Wände haben, beispielsweise eine Wand mit einer Lage aus Papier und mindestens einer luftundurchlässigen Folienlage. Ein Anwendungsbeispiel für solche Säcke sind aufblasbare Säcke, die beim Transport von Frachtgütern als Stützkissen eingesetzt werden.For certain applications, sacks are required that have multi-layer walls, for example a wall with a layer of paper and at least one air-impermeable film layer. An application example for such sacks are inflatable sacks used as support pillows when transporting cargo become.

Insbesondere bei mehrlagigen Säcken mit relativ großer Länge erweist es sich oft als schwierig, die Schlauchabschnitte sauber übereinanderzustapeln. Wenn bei dem Stapelvorgang ein frisch zugeführter Schlauchabschnitt über den obersten bereits auf dem Stapel liegenden Schlauchabschnitt geschoben oder gezogen wird, können die einzelnen Materiallagen leicht gegeneinander verrutschen und/oder Falten bilden, so daß ein sauberes Stapeln und eine einwandfreie Weiterverarbeitung nicht möglich ist.It often proves to be particularly useful for multi-layer bags with a relatively long length difficult to stack the hose sections neatly on top of each other. If at the stacking process a freshly fed tube section over the top already pushed or pulled hose section lying on the stack the individual layers of material can easily slip against each other and / or Form folds, so that clean stacking and perfect further processing not possible.

Aufgabe der Erfindung ist es, eine Vorrichtung zu schaffen, die insbesondere auch bei Schlauchabschnitten aus biegeschlaffem oder mehrlagigem Material eine saubere Stapelung ermöglicht.The object of the invention is to provide a device which, in particular also for hose sections made of flexible or multilayer material enables clean stacking.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Transporteinrichtung einen Obertransport und einen Untertransport aufweist und daß der Untertransport im Bereich der Stapelstation durch zwei endlose Transportgurte gebildet wird, die oberhalb der Stapelstation außerhalb der seitlichen Ränder der Schlauchabschnitte umlaufen und durch mindestens zwei in gleichmäßigen Abständen angeordnete Querträger verbunden sind, deren Abstände den Abständen der vorauslaufenden Kanten der nacheinander zugeführten Schlauchabschnitte entsprechen.This object is achieved in that the transport device has a top feed and a bottom feed and that the bottom feed formed by two endless conveyor belts in the area of the stacking station which is above the stacking station outside the side edges of the Circulate hose sections and at least two at equal intervals arranged cross members are connected, the distances between the distances the leading edges of the successively fed tube sections correspond.

Mit Hilfe der Transporteinrichtung werden die Schlauchabschnitte oberhalb des zu bildenden Stapels zugeführt. Dabei wird jeweils die vorauslaufende Kante eines Schlauchabschnitts klemmend zwischen dem Obertransport und einem der Querträger des Untertransports gehalten. Wenn die Stapelposition erreicht ist, erreicht der Querträger des Untertransports die Umlenkrolle, an der die Transportgurte umgelenkt werden, und folglich wird die Klemmung der vorauslaufenden Kante zwischen Obertransport und Untertransport aufgehoben, so daß der Schlauchabschnitt auf den Stapel fallengelassen wird. Während der nächste Schlauchabschnitt mit dem nachfolgenden Querträger zugeführt wird, läuft der umgelenkte Querträger am unteren Trumm der Transportgurte zurück. Er bewegt sich dabei auf einer Bahn, die ebenfalls noch oberhalb des zu bildenden Stapels liegt. Der nachschleppende hintere Teil des neu zugeführten Schlauchabschnittes, der nur an der vorderen Kante klemmend gehalten wird, wird daher durch den zurücklaufenden Querträger von der Oberseite des Stapels ferngehalten, so daß er nicht über den Stapel streicht und folglich die dort vorhandenen Schlauchabschnitte nicht verschieben kann. Erst wenn auch der neu zugeführte Schlauchabschnitt fallengelassen wird, hat sich der untere Querträger so weit zurückbewegt, daß er die nachlaufende Kante dieses Schlauchabschnitts freigibt.With the help of the transport device, the hose sections above the supplied to form stacks. The leading edge of each Hose section clamped between the top feed and one of the Cross member of the lower feed held. When the stack position is reached the cross member of the lower feed reaches the deflection roller on which the transport belts be redirected, and consequently the clamping of the leading Edge between top feed and bottom feed lifted so that the Hose section is dropped onto the stack. During the next one Hose section is fed with the subsequent cross member, the runs deflected cross members on the lower run of the transport belts. He moves itself on a path that is also above the path to be formed Stack. The trailing rear part of the newly fed Hose section, which is held clamped only at the front edge, is therefore due to the returning cross member from the top of the stack kept away so that he doesn't stroke the stack and consequently the one there cannot move existing hose sections. Only when that too newly fed hose section is dropped, the lower one Cross member moved back so far that it trailing edge this Hose section releases.

Gegenstand der Erfindung ist auch ein Verfahren zum Stapeln von Schlauchabschnitten, insbesondere aus mehrlagigem Material, für die Herstellung von Säkken, bei dem ein Schlauchabschnitt mit seiner vorauslaufenden Kante klemmend zwischen einem Querträger eines Untertransports und einem Obertransport gehalten und in eine Position oberhalb der Stapelstation zugeführt wird, während ein anderer Querträger des Untertransports, der oberhalb der Stapelstation zum stromaufwärtigen Ende der Transporteinrichtung zurückläuft, den nachschleppenden rückwärtigen Teil des Schlauchabschnittes vom Stapel fernhält, bis die vorauslaufende Kante von dem ersten Querträger freigegeben wird und der Schlauchabschnitt auf den Stapel fällt. The invention also relates to a method for stacking hose sections, especially of multi-layer material, for the production of bags, in which a hose section clamps with its leading edge between a cross member of a lower feed and an upper feed held and fed into a position above the stacking station, while another cross member of the lower feeder, which is above the stacking station runs back to the upstream end of the transport device keeps the trailing rear part of the hose section away from the stack, until the leading edge is released from the first cross member and the hose section falls onto the stack.

Vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen.Advantageous embodiments of the invention result from the subclaims.

Bevorzugt hat der Untertransport genau zwei Querträger, die diametral zueinander an den Transportgurten angeordnet sind.The lower feed preferably has exactly two crossbeams, which are diametrical to one another are arranged on the conveyor belts.

Vorzugsweise reicht der Untertransport am stromabwärtigen Ende der Transporteinrichtung etwas über den Obertransport hinaus, so daß der freigegebene Schlauchabschnitt ungehindert auf den Stapel fallen kann.The lower feed at the downstream end of the transport device is preferably sufficient something beyond the top feed, so that the released Hose section can fall freely onto the stack.

Der freigegebene Schlauchabschnitt kann durch eine oder mehrere Blattfedern, die stationär im Obertransport angeordnet sind, in Richtung auf den Stapel niedergedrückt werden, so daß das Ablegen des Schlauchabschnitts auf dem Stapel beschleunigt wird.The released hose section can be by one or more leaf springs, which are arranged stationary in the top feed, depressed in the direction of the stack so that the placing of the hose section on the stack is accelerated.

Die bündige Ablage der Schlauchabschnitte auf dem Stapel kann durch am Stapeltisch angeordnete Anschläge unterstützt werden. Vorzugsweise wird der Stapeltisch durch einen Förderer gebildet, mit dem der Stapel abtransportiert werden kann, sobald die gewünschte Stapelhöhe erreicht ist.The flush placement of the hose sections on the stack can be done on the stacking table arranged stops are supported. Preferably the stacking table formed by a conveyor with which the stack can be removed can, as soon as the desired stack height is reached.

Die oberhalb der Stapelstation angeordnete Transporteinrichtung ist vorzugsweise einer Trenneinrichtung nachgeschaltet, in der der endlose Schlauch in einzelne Schlauchabschnitte aufgeteilt wird. Die Transportgeschwindigkeit der Transporteinrichtung oberhalb der Ablagestation ist vorzugsweise größer als die Transportgeschwindigkeit, mit der der Schlauch der Trenneinrichtung zugeführt wird. Da somit die Schlauchabschnitte beim Eintritt in die Stapelvorrichtung beschleunigt werden, entstehen zwischen den aufeinanderfolgend zugeführten Schlauchabschnitten Zwischenräume, die genügend Zeit für die Ablage der Schlauchabschnitte auf dem Stapel schaffen.The transport device arranged above the stacking station is preferred downstream of a separator in which the endless hose in individual hose sections is divided. The transport speed of the Transport device above the storage station is preferably larger than that Transport speed at which the hose is fed to the separating device becomes. Since the hose sections are thus accelerated when they enter the stacking device are created between the successively fed Gaps between spaces that allow enough time for filing Create hose sections on the stack.

Der Untertransport muß so mit der Zufuhr der Schlauchabschnitte synchronisiert sein, daß jeder Querträger zeitgleich mit der vorauslaufenden Kante eines zugeführten Schlauchabschnitts am stromaufwärtigen Ende der Transporteinrichtung eintrifft. Da die aufgrund der Beschleunigung zwischen den einzelnen Schlauchabschnitten entstehenden Zwischenräume von der Differenz der Transportgeschwindigkeit abhängig sind, lassen sich die Abstände zwischen den vorauslaufenden Kanten der aufeinanderfolgenden Schlauchabschnitte an den festen Abstand der Querträger des Untertransportes anpassen.The bottom feed must be synchronized with the supply of the hose sections be that each cross member at the same time as the leading edge of a supplied hose section at the upstream end of the transport device arrives. Because of the acceleration between each Gaps between the resulting tube speed difference are dependent, the distances between the leading Edges of the successive hose sections on the fixed Adjust the distance between the cross members of the lower feed.

Insbesondere bei mehrlagigen Schlauchabschnitten ist die Trenneinrichtung vorzugsweise als Abreißkopf ausgebildet, mit der die einzelnen Materiallagen des Schlauches an vorab gebildeten Perforationsstellen abgerissen werden. Durch die Beschleunigung der Schlauchabschnitte beim Eintritt in die Transporteinrichtung der Stapelvorrichtung kann dann zugleich die zum Abreißen der Schlauchabschnitte benötigte Zugspannung erzeugt werden.The separating device is particularly useful in the case of multilayer hose sections preferably designed as a tear-off head with which the individual layers of material Hose are torn off at previously formed perforation points. By the acceleration of the hose sections when entering the transport device the stacking device can then also be used to tear off the Hose sections required tension are generated.

Vorzugsweise hat die Transporteinrichtung der Stapelvorrichtung am stromaufwärtigen Ende einen Einlaufabschnitt, in dem sich der vertikale Abstand zwischen dem Obertransport und dem Untertransport verengt, bis schließlich die vorauslaufende Kante des Schlauchabschnittes geklemmt wird. Die Klemmstelle wird vorzugsweise durch eine Klemmwalze definiert, die in Längsrichtung verstellbar ist, so daß eine Anpassung an unterschiedliche Längen der Schlauchabschnitte ermöglicht wird.The transport device of the stacking device preferably has on the upstream End of an inlet section in which the vertical distance between the top feed and the bottom feed narrowed until finally the leading edge of the hose section is clamped. The nip is preferably defined by a pinch roller that is adjustable in the longitudinal direction is, so that an adaptation to different lengths of the hose sections is made possible.

Im folgenden wird ein Ausführungsbeispiel der Erfindung anhand der Zeichnung näher erläutert.The following is an embodiment of the invention with reference to the drawing explained in more detail.

Die in Figur 1 gezeigte Stapelvorrichtung weist eine Stapelstation 10 auf, oberhalb derer eine Transporteinrichtung 12 mit einem Obertransport 14 und einem Untertransport 16 angeordnet ist.The stacking device shown in FIG. 1 has a stacking station 10, above of which a transport device 12 with an upper transport 14 and a Lower transport 16 is arranged.

Ein endloser, mehrlagiger Schlauch 18 wird von rechts in Figur 1 mit Hilfe oberer und unterer Transportbänder 20, 22 zugeführt. Die Wände des Schlauches 18 bestehen aus mehreren Materiallagen, die vorab, vorzugsweise an in Längsrichtung etwas gegeneinander versetzten Positionen perforiert worden sind.An endless, multi-layer hose 18 is from the right in Figure 1 with the help of the upper and lower conveyor belts 20, 22 fed. The walls of the hose 18 consist of several layers of material in advance, preferably in the longitudinal direction slightly offset positions have been perforated.

Hinter den Transportbändern 20, 22 tritt der Schlauch 18 in einen Abreißkopf 24 ein, der ebenfalls durch obere und untere Transportbänder 26, 28 gebildet wird. Die Transportgeschwindigkeit des Abreißkopfes 24 ist zumindest phasenweise größer als die Transportgeschwindigkeit der Transportbänder 20, 22, so daß in dem Schlauch 18 eine Zugspannung erzeugt wird. Wenn die erwähnte Perforationsstelle den Zwischenraum zwischen dem stromabwärtigen Ende der Transportbänder 20, 22 und dem stromaufwärtigen Ende des Abreißkopfes 24 erreicht, führt diese Zugspannung dazu, daß ein Schlauchabschnitt 30 von dem endlosen Schlauch 18 abgerissen wird.After the conveyor belts 20, 22, the hose 18 enters a tear-off head 24 a, which is also formed by upper and lower conveyor belts 26, 28 becomes. The transport speed of the tear-off head 24 is at least in phases greater than the transport speed of the conveyor belts 20, 22, so that a tension is generated in the hose 18. If the mentioned Perforation point the space between the downstream end of the Conveyor belts 20, 22 and the upstream end of the tear-off head 24 reached, this tension leads to a hose section 30 of the endless hose 18 is torn off.

Die vorauslaufende Kante des Schlauchabschnittes 30 ist in diesem Augenblick bereits in einen Einlaufabschnitt 32 der Transporteinrichtung 12 eingetreten. Der Einlaufabschnitt wird durch mehrere parallele obere und untere Transportbänder 34, 36 gebildet, deren Transportgeschwindigkeit mit der des Abreißkopfes 24 übereinstimmt. Der vertikale Abstand zwischen den oberen Transportbändern 34 und den unteren Transportbändern 36 nimmt in Transportrichtung allmählich ab, so daß ein sicheres Einführen der vorauslaufenden Kante des Schlauchabschnitts 30 ermöglicht wird. Eine Klemmwalze 38 lenkt den unteren Trumm der oberen Transportbänder 34 etwas nach unten ab, so daß die vorauslaufende Kante des Schlauchabschnitts 30 etwa in dem Augenblick klemmend erfaßt wird, in dem die nachlaufende Kante vom Endlosschlauch abgerissen wird. Die Klemmwalze 38 ist zur Anpassung an die Länge der Schlauchabschnitte 30 längenverstellbar.The leading edge of the hose section 30 is at this moment has already entered an inlet section 32 of the transport device 12. The inlet section is made up of several parallel upper and lower conveyor belts 34, 36 formed, the transport speed with that of the tear-off head 24 matches. The vertical distance between the top conveyor belts 34 and the lower conveyor belts 36 takes in the transport direction gradually, so that a safe insertion of the leading edge of the Hose section 30 is made possible. A pinch roller 38 steers the lower one Trumm of the upper conveyor belts 34 down a little, so that the leading Edge of the hose section 30 jamming at about the moment is detected in which the trailing edge is torn off the endless hose becomes. The pinch roller 38 is to adapt to the length of the hose sections 30 adjustable in length.

Die durch den Einlaufabschnitt 32 gebildete Transportbahn ist leicht aufwärts geneigt, so daß die Schlauchabschnitte beim Weitertransport eine gewisse Höhe oberhalb der Stapelstation 10 erreichen. In dem Bereich oberhalb der Stapelstation wird der Obertransport 14 durch mehrere parallele, waagerecht verlaufende Transportbänder 14 gebildet, die mit den Transportbändern 34 eine Umlenkwalze 42 gemeinsam haben. Der Untertransport 16 wird hier durch zwei Transportgurte 44 gebildet, die über zwei Umlenkwalzen 46 laufen und die, wie deutlicher in Figur 2 zu erkennen ist, außerhalb der seitlichen Ränder der Schlauchabschnitte 30 liegen. Die Transportgurte 44 sind lediglich an zwei Stellen durch Querträger 48, 50 verbunden und sind durch formschlüssige Antriebe (z. B. Zahnriemen) synchronisiert. Die Querträger 48, 50 sind an den Transportgurten 44 in diametral gegenüberliegenden Positionen angeordnet, so daß sie auf beiden Wegen längs der Transportgurte 44 gleiche Abstände zueinander aufweisen und somit jeweils gleichzeitig die Umlenkwalzen 46 erreichen. In dem in Figur 1 gezeigten Zustand wird die vorauslaufende Kante eines Schlauchabschnittes 30 klemmend durch die Transportbänder 40 des Obertransportes und durch den Querträger 48 gehalten. Das nachschleppende rückwärtige Ende dieses Schlauchabschnittes 30 liegt auf dem anderen Querträger 50 auf, der am unteren Trumm der Transportgurte 44 zur stromaufwärtigen Umlenkwalze 46 zurückläuft. Auf diese Weise wird der Schlauchabschnitt 30 von einem bereits gebildeten Stapel 52 von Schlauchabschnitten ferngehalten, der in der Stapelstation 10 auf einem als Förderer ausgebildeten Stapeltisch 54 liegt.The transport path formed by the inlet section 32 is slightly upward inclined so that the hose sections a certain height during further transport Reach above the stacking station 10. In the area above the stacking station the upper transport 14 is made by several parallel, horizontally running Conveyor belts 14 formed with the conveyor belts 34, a deflection roller 42 have in common. The lower conveyor 16 is here by two conveyor belts 44 formed, which run over two deflection rollers 46 and which, as more clearly can be seen in Figure 2, outside the side edges of the hose sections 30 lie. The transport belts 44 are only in two places Crossbeams 48, 50 are connected and are connected by positive drives (e.g. Timing belt) synchronized. The cross members 48, 50 are on the conveyor belts 44 arranged in diametrically opposite positions so that they are on both Because of the length of the conveyor belts 44 have the same distances from each other and thus simultaneously reach the deflection rollers 46. In the in FIG shown state becomes the leading edge of a hose section 30 jammed by the conveyor belts 40 of the upper conveyor and by the Cross member 48 held. The trailing rear end of this Hose section 30 rests on the other cross member 50, which is at the bottom The conveyor belts 44 run back to the upstream deflection roller 46. In this way, the hose section 30 is formed by an already formed one Stack 52 kept away from hose sections in the stacking station 10 lies on a stacking table 54 designed as a conveyor.

In Figur 2 ist die Stapelvorrichtung in der Draufsicht gezeigt. Aus Gründen der Übersichtlichkeit sind auf der Zufuhrseite nur die oberen Transportbänder 20, 36 und 34 mit ihren jeweiligen Umlenkwalzen dargestellt. Im stromabwärtigen Bereich sind jedoch auch die Transportgurte 44 des Untertransportes eingezeichnet. Man erkennt, daß der Abstand zwischen diesen Transportgurten 44 größer ist als die Breite des zugeführten Schlauchabschnittes 30, so daß der Schlauchabschnitt, wenn er freigegeben wird, zwischen diesen Transportgurten 44 hindurchfallen und auf den Stapel 52 gelangen kann. Die Ablage des Schlauchabschnittes 30 auf dem Stapel 52 wird durch Blattfedern 56 unterstützt, die sich in Längsrichtung zwischen den Transportgurten 40 des Obertransportes erstrecken und so an einem stationären Träger 58 befestigt sind, daß sie mit ihren freien Enden im Bereich der vorauslaufenden Kante auf den Schlauchabschnitt 30 drücken.In Figure 2, the stacking device is shown in plan view. Because of For clarity, only the upper conveyor belts 20 are on the feed side, 36 and 34 with their respective deflection rollers. In the downstream In the area, however, the transport belts 44 of the lower transport are also shown. It can be seen that the distance between these conveyor belts 44 is greater than the width of the supplied hose section 30, so that the Section of hose, when released, between these conveyor belts 44 can fall through and get onto the stack 52. The filing of the Hose section 30 on the stack 52 is supported by leaf springs 56, which is in the longitudinal direction between the transport belts 40 of the upper transport extend and are thus attached to a stationary support 58, that with their free ends in the area of the leading edge on the Press hose section 30.

Figur 3 zeigt die Stapelvorrichtung in einem Zustand, der zeitlich etwas später liegt als der in Figur 1 gezeigte Zustand. Der obere Querträger 48 hat hier gerade das stromabwärtige Ende des Obertransportes 14 passiert, so daß der Schlauchabschnitt 30 unterstützt durch die Wirkung der Blattfedern 56 auf den Stapel 52 fällt. Der Schlauchabschnitt hat noch eine gewisse Geschwindigkeitskomponente in Bewegungsrichtung, die jedoch bei der bevorzugten Transportgeschwindigkeit der Transporteinrichtung 12 (vorzugsweise kleiner als 60 m pro Minute) nur gering ist, so daß der Schlauchabschnitt paßgenau auf dem Stapel 52 zu liegen kommt. Erforderlichenfalls wird die Ausrichtung auf dem Stapel durch einen Anschlag 60 unterstützt, der fest auf dem Stapeltisch 54 angebracht ist.FIG. 3 shows the stacking device in a state which is somewhat later in time lies as the state shown in Figure 1. The upper cross member 48 has just here the downstream end of the upper conveyor 14 passes, so that the Hose section 30 supported by the action of the leaf springs 56 on the Stack 52 falls. The hose section still has a certain speed component in the direction of movement, but at the preferred transport speed the transport device 12 (preferably less than 60 m per Minute) is only slight, so that the tube section fits snugly on the stack 52 comes to rest. If necessary, the alignment on the stack supported by a stop 60, which is firmly attached to the stacking table 54 is.

Die rückwärtige Kante des Schlauchabschnittes 30 passiert in Figur 3 gerade den unteren Querträger 50 und wird somit ebenfalls auf den Stapel 52 fallengelassen.The rear edge of the hose section 30 just passes in FIG. 3 the lower cross member 50 and is thus also dropped onto the stack 52.

Figur 4 zeigt den Zustand zu einem noch späteren Zeitpunkt. Der Querträger 48 ist hier gerade an der Umlenkwalze 46 umgelenkt worden und läuft nun auf der Unterseite des Untertransportes zurück. Gleichzeitig hat der andere Querträger 50 die entsprechende Position auf der Oberseite des Untertransportes erreicht, wo er nun zusammen mit den Transportbändern 40 des Obertransportes die vorauslaufende Kante des nächsten Schlauchabschnittes 30 erfaßt, der zeitgerecht vom Einlaufabschnitt 32 zugeführt wird. Dieser Schlauchabschnitt wird nun weiter nach vom gezogen. Wenn seine nachlaufende Kante die hintere Umlenkwalze 46 des Untertransportes passiert hat und herabfällt, wird sie durch den zurücklaufenden Querträger 48 aufgefangen, so daß sie nicht mit dem Stapel 52 in Berührung kommt. Schließlich wird wieder der in Figur 1 gezeigte Zustand erreicht, so daß ein neuer Zyklus beginnen kann.Figure 4 shows the state at a later time. The cross member 48 has just been deflected here on the deflection roller 46 and is now running on the Bottom of the bottom feed back. At the same time, the other cross member 50 reaches the corresponding position on the top of the lower feed, where he now together with the conveyor belts 40 of the upper transport leading edge of the next hose section 30 detects the timely is supplied from the inlet section 32. This section of tubing will now moved on from. If its trailing edge the rear deflecting roller 46 of the sub-conveyor has passed and falls, it will be through the returning cross member 48 caught so that it does not stack 52 comes into contact. Finally, the state shown in Figure 1 again reached so that a new cycle can begin.

Wenn der Stapel 52 die gewünschte Höhe erreicht hat, wird das den Stapeltisch 54 bildende Förderband angetrieben, so daß der Stapel abtransportiert wird und in der Stapelstation 10 ein neuer Stapel gebildet werden kann.When the stack 52 has reached the desired height, it becomes the stacking table 54 forming conveyor belt driven so that the stack is removed and a new stack can be formed in the stacking station 10.

Bei der beschriebenen Stapelvorrichtung kann die Länge der Schlauchabschnitte 30 innerhalb gewisser Grenzen variieren, da der Abstand zwischen den Querträgern 48 und 50 nicht mit der genauen Länge der Schlauchabschnitte sondern vielmehr mit den Abständen zwischen den vorauslaufenden Kanten der aufeinanderfolgenden Schlauchabschnitte übereinstimmen muß. Kürzere Längen der Schlauchabschnitte können somit durch entsprechend größere Zwischenräume ausgeglichen werden.In the stacking device described, the length of the tube sections can 30 vary within certain limits because of the distance between the cross members 48 and 50 not with the exact length of the hose sections but rather with the distances between the leading edges of the successive Hose sections must match. Shorter lengths of the Hose sections can thus be made by correspondingly larger gaps be balanced.

In einer modifizierten Ausführungsform kann der Untertransport 16 auch mehr als zwei gleichmäßig auf der Länge der Transportgurte 44 verteilte Querträger aufweisen. In diesem Fall werden die Schlauchabschnitte 30 über eine größere Länge transportiert, bevor sie auf dem Stapel abgelegt werden. Die Querträger 48, 50 können dann lösbar an den Transportgurten 44 befestigt sein, so daß sich ihre Anzahl variieren läßt.In a modified embodiment, the lower feed 16 can also do more as two cross members evenly distributed over the length of the conveyor belts 44 exhibit. In this case, the tube sections 30 are larger Length transported before they are placed on the stack. The cross beams 48, 50 can then be releasably attached to the conveyor belts 44 so that their number can be varied.

Da mit der beschriebenen Vorrichtung zumindest weitgehend vermieden wirdwird, daß ein neu auf den Stapel zugeführter Schlauchabschnitt über die Oberfläche des bereits gebildeten Stapels schleppt, wird insbesondere bei empfindlichen mehrlagigen Schlauchabschnitten ein sauberes Stapeln ermöglicht.Since the device described is at least largely avoided, that a hose section newly fed onto the stack over the surface of the already formed stack drags, especially in sensitive multilayer hose sections enables clean stacking.
