Description

Die gegenständliche Erfindung betrifft eine Vorrichtung zum Unterteilen einer Papierbahn, welche auf eine rotierende Trommel aufgewickelt wird, für den Übergang des Wickelvorganges der Papierbahn auf eine rotierende leere Trommel unter Verwendung eines Reißbandes, welches sich quer zur Papierbahn erstreckt und dessen freies Ende an der leeren Trommel befestigbar ist, wodurch es auf dieser schraubenlinienförmig aufgewickelt wird und hierdurch die Papierbahn unterteilt, mit einem in Richtung der Achse der leeren Trommel seitlich außerhalb derselben quer zu dieser Achse verstellbaren Schlitten, an welchem eine Einrichtung zum Festhalten des Reißbandes angeordnet ist.The present invention relates to a device for dividing a paper web, which is wound on a rotating drum is, for the transition of the winding process of the paper web to a rotating empty drum using a tear tape, which extends across the paper web and its free end at the empty Drum is attachable, making it helical on this is wound up and thereby divides the paper web, with a in the direction of the axis of the empty drum laterally outside it carriage adjustable transversely to this axis, on which a device is arranged to hold the tear tape.

Bei einer derartigen Vorrichtung, welche aus der US PS 4 757 950 bekannt ist, wird das Reißband durch einen sich quer zur Papierbahn von einer Seite der Papierbahn zur anderen Seite der Papierbahn erstreckenden Kanal hindurchgeschoben, wobei sich dessen freies Ende im Bereich des zwischen den beiden Trommeln gebildeten Spaltes befindet. Sobald der Trennvorgang einsetzen soll, wird das Reißband mittels einer Fördervorrichtung vorgeschoben, sodaß dessen freies Ende an die leere Trommel zur Anlage kommt und an dieser mittels eines Klebeauftrages befestigt wird. In der Folge wird das Reißband aus dem Kanal herausgerissen und wird es durch die Rotation der leeren Trommel auf dieser schraubenlinienförmig aufgewickelt, wobei es die Papierbahn unterteilt. Hierauf wird die Papierbahn auf der leeren Trommel aufgewickelt.In such a device, which is known from US Pat. No. 4,757,950 is known, the tear tape through a cross to the paper web from one side of the paper web to the other side of the paper web extending channel pushed through, with its free end in the area of the gap formed between the two drums located. As soon as the separation process is to start, the tear tape advanced by a conveyor so that its free end comes to rest on the empty drum and on this by means of a Glue application is attached. As a result, the tear tape from the Channel ripped out and it gets rotated by the empty drum wound on this helically, it being the paper web divided. Then the paper web is placed on the empty drum wound up.

Da sich bei dieser Vorrichtung die Fördervorrichtung für das Reißband an einer ersten Seite der Papierbahn befindet und der Trennvorgang an der anderen Seite der Papierbahn einsetzt, besteht somit das Erfordernis, das Reißband durch den sich quer zur Papierbahn erstreckenden Kanal hindurchzuschieben und in den zwischen den beiden Trommeln befindlichen Spalt einzuschieben. Hierfür muß das Reißband eine hinreichende Steifigkeit aufweisen, damit diese Schubbewegung ausführbar ist. Aus diesem Grund sind für diese Vorrichtungen verwendete Reißbänder aus nebeneinander befindlichen und miteinander verklebten Papierschnüren gefertigt. Since this device is the conveyor for the tear tape is on a first side of the paper web and the separation process is on the other side of the paper web, there is a need the tear tape through the one extending transversely to the paper web Slide channel and in between the two drums insert the existing gap. For this, the tear tape must be sufficient Have rigidity so that this pushing movement can be carried out is. For this reason, tear tapes are used for these devices from side by side and glued together Made of paper cords.

Aus der EP 708 049 A1 ist weiters eine Vorrichtung bekannt, bei welcher sich die Fördereinrichtung für das Reißband auf derjenigen Seite der Papierbahn befindet, an welcher der Trennvorgang einsetzt. Da somit das Reißband durch den Kanal hindurchgezogen wird und nur zur leeren Trommel hin gefördert zu werden braucht, kann es eine wesentlich geringere Steifigkeit aufweisen. Demnach können für diese Vorrichtung Reißbänder verwendet werden, welche z.B. aus gefalzten Papierblättern gefertigt sind, wobei sie eine wesentlich geringere Stärke aufweisen.A device is also known from EP 708 049 A1, in which the conveyor for the tear tape on that side the paper web on which the separation process begins. There thus the tear tape is pulled through the channel and only for empty drum needs to be promoted, it can be an essential have lower rigidity. Accordingly, for this device Tear tapes are used, e.g. from folded sheets of paper are made, having a much lower strength.

Es wird in diesem Zusammenhang darauf verwiesen, daß derartige Reißbänder zwar eine hohe Reißfestigkeit aufweisen müssen, daß sie jedoch deshalb möglichst dünn ausgebildet sein sollen, da sie auf die leere Trommel aufgewickelt werden, über welche in der Folge die Papierbahn aufgewickelt wird, wobei diejenigen Lagen der Papierbahn, welche durch das Reißband infolge von Einprägungen markiert werden, einen Ausschuß darstellen. Da das Reißband mit dem Ausschuß der Papierbahn einer Wiederverarbeitung zuführbar sein soll, soll muß es aus Papier gefertigt sein. Da zudem die Trommeln mit einer Gummibeschichtung ausgebildet sind, muß das Reißband zudem möglichst weich und möglichst wenig steif sein. Soferne allerdings diese Forderungen erfüllt sind, bedingt es Schwierigkeiten, das Reißband zur leeren Trommel hin zu fördern, damit es an dieser zur Anlage kommt, um den Trennvorgang einleiten zu können.In this connection, reference is made to the fact that such Tear tapes must have a high tear strength that they however, should be as thin as possible because they are on the empty drum, over which the Paper web is wound up, with those layers of the paper web, which are marked by the tear tape as a result of impressions, to constitute a committee. Since the tear tape with the committee of Paper web should be able to be fed to a reprocessing, it should be made of paper. Because the drums also have a rubber coating trained, the tear tape must also if possible be soft and as little stiff as possible. However, if these demands are fulfilled, it causes difficulties in emptying the tear tape To promote drum so that it comes to the system to the To be able to initiate the separation process.

Die aus der US PS 4 757 950 bekannte Vorrichtung ist weiters auf der anderen Seite der Papierbahn mit einer Einrichtung zum Festhalten des Reißbandes ausgebildet, welche mittels eines Schlittens an die Oberfläche der leeren Trommel herangeführt werden kann. Sobald das freie Ende des Reißbandes an der leeren Trommel befestigt wurde, muß es von der Einrichtung, von welcher es festgehalten wird, freigegeben werden.The device known from US Pat. No. 4,757,950 is also on the other side of the paper web with a device for holding the Tear tape formed, which by means of a carriage to the surface the empty drum can be introduced. Once the free End of the tear tape has been attached to the empty drum, it must released by the institution from which it is held.

Bei dieser bekannten Vorrichtung ist diese Einrichtung zum Festhalten des Reißbandes durch zwei zueinander verschwenkbare Klemmbacken gebildet. Sobald der Trennvorgang einsetzt, wird das Reißband aus diesen beiden Klemmbacken herausgerissen. Da dabei das Reißband als steifes Band ausgebildet ist, hält es den durch diesen Vorgang verursachten Belastungen stand. Sobald jedoch ein wesentlich dünneres Reißband verwendet wird, besteht die Gefahr, daß es beim Herausreißen aus den Klemmbacken zerrissen wird, wodurch der Trennvorgang der Papierbahn nicht mehr durchführbar wäre.In this known device, this device is for holding of the tear tape by means of two clamping jaws that can be swiveled towards each other educated. As soon as the separation process begins, the tear tape becomes from this torn out of both jaws. Since the tear tape as rigid band is formed, it holds the caused by this process Loads stood. However, once a much thinner Tear tape is used, there is a risk of it being torn out is torn from the jaws, causing the separation process of the Paper web would no longer be feasible.

Der gegenständlichen Erfindung liegt demnach die Aufgabe zugrunde, die auf dem Schlitten angeordnete Einrichtung zum Festhalten und Vorschieben des Reißbandes so auszubilden, daß ein Zerreißen des Reißbandes mit Sicherheit ausgeschlossen wird. Dies wird erfindungsgemäß dadurch erzielt, daß die Einrichtung zum Festhalten des Reißbandes durch eine Saugeinrichtung gebildet ist, welche durch eine über einen Schlauch angeschlossene Unterdruckquelle steuerbar ist. Vorzugsweise ist zudem eine Druckluftdüse vorgesehen, durch welche das Reißband zur Einrichtung zum Festhalten des Reißbandes hin bewegbar ist.The object of the invention is therefore based on the object the device arranged on the slide for holding and advancing of the tear tape so that tearing of the tear tape is definitely excluded. This is according to the invention achieved in that the means for holding the tear tape is formed by a suction device, which by a via a Hose connected vacuum source is controllable. Preferably a compressed air nozzle is also provided, through which the tear tape is movable towards the device for holding the tear tape.

Nach weiteren vorzugsweisen Merkmalen ist die Einrichtung zum Festhalten des Reißbandes am Schlitten verschwenkbar gelagert, wobei sie während der Bewegung des Schlittens gegenüber diesem verschwenkt wird. Hierfür kann diese Einrichtung von einem Schenkel eines Winkelhebels quer abragen, welcher in seinem Scheitel verdrehbar gelagert ist, wobei das freie Ende des anderen Schenkels in einer gestellfesten Kulisse geführt ist.According to other preferred features, the device for holding on of the tear tape on the sled pivotably, being pivoted relative to the carriage during the movement thereof becomes. For this purpose, this device can be from one leg of an angle lever protrude transversely, which is rotatably mounted in its apex, the free end of the other leg being fixed in a frame Scenery is led.

Die nachstehenden Erläuterungen beziehen sich auf eine Vorrichtung gemäß der EP 708 049 A1, welche zur Lösung der Aufgabe, auch ein sehr wenig steifes Reißband verwenden zu können, mit einer zusätzlichen Einrichtung ausgebildet ist. Der Aufbau und die Wirkungsweise dieser zusätzlichen Einrichtung sind nachstehend erläutert.The explanations below relate to a device according to EP 708 049 A1, which is used to solve the problem to be able to use very little stiff tear tape, with an additional one Device is trained. The structure and the mode of operation this additional device is explained below.

Diese Vorrichtung ist mit einem sich quer zu den beiden Trommeln, auf welche die Papierbahn aufgewickelt wird, erstreckenden und unterhalb der Papierbahn angeordneten Kanal 3 ausgebildet, welcher nahe dem zwischen einer Antriebstrommel 11 und der leeren Trommel 12 befindlichen Spalt 10 endet. Im Kanal 3 ist ein Schlitten 31 geführt, durch welchen das freie Ende des Reißbandes 4 von einer Seite der Papierbahn zur anderen Seite hin bewegbar ist. Hierdurch wird das freie Ende des Reißbandes 4 in den Bereich des zwischen den beiden Trommeln 11 und 12 befindlichen Spaltes 10 gefördert. Zur Bewegung des Schlittens 31 dient ein Zugelement 32, welches am Ende des Kanals 3 um eine Umlenkrolle 33 geführt ist. Zudem sind am Schlitten 31 zwei Rollen 34 und 35 gelagert, zwischen welchen das Reißband 4 geführt ist.This device is based on a cross to the two drums which the paper web is wound, extending and below the paper web arranged channel 3 which is close to the located between a drive drum 11 and the empty drum 12 Gap 10 ends. A slide 31 is guided in channel 3 which the free end of the tear tape 4 from one side of the paper web is movable to the other side. This will make the free end of the Tear tape 4 in the area between the two drums 11 and 12 located gap 10 promoted. For moving the slide 31 serves a tension element 32, which at the end of the channel 3 by a Deflection roller 33 is guided. There are also two rollers 34 on the slide 31 and 35, between which the tear tape 4 is guided.

In Fig. 1 ist eine Lage des Schlittens 31 dargestellt, in welcher sich dieser etwas vor seiner Endstellung befindet.
Demgegenüber ist in Fig. 2 die Endstellung des Schlittens 31 dargestellt. Sobald das Reißband 4 in den zwischen den beiden Trommeln 11 und 12 befindlichen Spalt 10 eingeführt und in der Folge an der leeren Trommel 12 befestigt werden soll, werden die beiden Rollen 34 und 35 angetrieben, wodurch das Reißband 4 vorgeschoben wird.
Dieses Stadium ist in Fig. 3 der Zeichnung dargestellt.
In Fig. 1, a position of the carriage 31 is shown, in which it is slightly before its end position.
In contrast, the end position of the slide 31 is shown in FIG. 2. As soon as the tear tape 4 is inserted into the gap 10 between the two drums 11 and 12 and subsequently to be attached to the empty drum 12, the two rollers 34 and 35 are driven, whereby the tear tape 4 is advanced.
This stage is shown in Fig. 3 of the drawing.

Da jedoch das Reißband 4 eine sehr geringe Steifigkeit aufweist bzw. sehr weich und elastisch ist, ist eine weitere Einrichtung 5 vorgesehen, welche von einem Rahmen 50 getragen ist und durch welche das Reißband 4 zur Einleitung des Trennvorganges vorgeschoben wird.
Wie dies aus den Fig. 1 bis 6 und Fig. 7 ersichtlich ist, befindet sich diese weitere Einrichtung 5 seitlich außerhalb der beiden Trommeln 11 und 12. Diese Einrichtung 5 enthält einen längs einer fest angeordneten Stange 51 verschiebbaren Schlitten 52, an welchem eine Halteeinrichtung 6 für das Reißband 4 verschwenkbar gelagert ist. Der Schlitten 52 ist hydraulisch, pneumatisch oder elektrisch quer zu den Rotationsachsen der beiden Trommeln 11 und 12 verschiebbar. Weiters ist am Schlitten 52 ein Winkelstück 53 gelagert, welches um eine Achse 54, die zu den Rotationsachsen der beiden Trommeln 11 und 12 parallel ausgerichtet ist, verdrehbar ist. An einem der freien Enden des Winkelstückes 53 ist eine Rolle 55 gelagert, welche in einer Kulisse 56 geführt ist. Vom anderen Ende des Winkelstückes 53 ragt in Richtung der Achsen der Trommeln 11 und 12 ein Balken 61 ab, welcher in den zwischen den beiden Trommeln 11 und 12 gebildeten Spalt 10 einragt. Das freie Ende des Balkens 61 ist mit Saugnäpfen 62 ausgebildet, an welche eine Saugleitung 63 anschließt.
However, since the tear tape 4 has a very low rigidity or is very soft and elastic, a further device 5 is provided, which is supported by a frame 50 and through which the tear tape 4 is advanced to initiate the separation process.
As can be seen from FIGS. 1 to 6 and 7, this further device 5 is located laterally outside the two drums 11 and 12. This device 5 contains a carriage 52 which can be displaced along a fixed rod 51 and on which a holding device 6 for the tear tape 4 is pivotally mounted. The carriage 52 is hydraulically, pneumatically or electrically displaceable transversely to the axes of rotation of the two drums 11 and 12. Furthermore, an angle piece 53 is mounted on the carriage 52, which can be rotated about an axis 54 which is aligned parallel to the axes of rotation of the two drums 11 and 12. At one of the free ends of the elbow 53, a roller 55 is mounted, which is guided in a backdrop 56. A beam 61 protrudes from the other end of the angle piece 53 in the direction of the axes of the drums 11 and 12 and protrudes into the gap 10 formed between the two drums 11 and 12. The free end of the bar 61 is formed with suction cups 62, to which a suction line 63 connects.

Die genaue Ausbildung des Balkens 61 ist aus den Fig. 8 und 9 ersichtlich. Wie daraus hervorgeht, ist der Balken 61 an seinem freien Ende mit drei Saugnäpfen 62 versehen, welche über die Saugleitung 63 zur Wirkung kommen. Zudem ist eine Blasdüse 66 vorgesehen, welche, wie insbesondere aus Fig. 7 ersichtlich ist, auf das Reißband 4 bzw. auf die Saugnäpfe 62 gerichtet ist.The exact design of the bar 61 can be seen from FIGS. 8 and 9. As can be seen from this, the beam 61 is at its free end provided with three suction cups 62, which via the suction line 63 to Come into effect. In addition, a blowing nozzle 66 is provided which, like 7 can be seen in particular on the tear tape 4 or on the Suction cups 62 is directed.

Sobald der Trennvorgang eingeleitet werden soll, wird die Blasdüse 66 eingeschaltet und wird die zu den Saugnäpfen 62 führende Saugleitung 63 an eine Unterdruckquelle angeschlossen. Hierdurch wird das Reißband 4 zu den Saugnäpfen 62 hin bewegt und durch diese erfaßt, wodurch es von diesen in seiner Lage gehalten wird. Dieses Stadium ist in Fig. 4 dargestellt.
In weiterer Folge wird der Schlitten 52 längs der Führungsstange 51 in Richtung der beiden Trommeln 11 und 12 bewegt. Hierdurch wird das Winkelstück 53 durch die in der Kulisse 56 geführte Rolle 55 im Uhrzeigersinn verschwenkt. Dieses Stadium ist in Fig. 5 dargestellt.
Hierdurch kommt das freie Ende des Reißbandes 4, welches mit einem Klebeauftrag 41 ausgebildet ist, an der leeren Trommel 12 zur Anlage, wodurch es an dieser befestigt wird. Dieses Stadium ist in Fig. 6 dargestellt.
Durch die Befestigung des Reißbandes 4 an der leeren Trommel 12, welche sich in Rotation befindet, wird der Trennvorgang eingeleitet.
As soon as the separation process is to be initiated, the blowing nozzle 66 is switched on and the suction line 63 leading to the suction cups 62 is connected to a vacuum source. As a result, the tear tape 4 is moved toward the suction cups 62 and is grasped by them, as a result of which it is held in position by them. This stage is shown in Fig. 4.
Subsequently, the carriage 52 is moved along the guide rod 51 in the direction of the two drums 11 and 12. As a result, the angle piece 53 is pivoted clockwise by the roller 55 guided in the link 56. This stage is shown in Fig. 5.
As a result, the free end of the tear tape 4, which is designed with an adhesive application 41, comes into contact with the empty drum 12, as a result of which it is attached to it. This stage is shown in Fig. 6.
The separation process is initiated by attaching the tear tape 4 to the empty drum 12, which is rotating.

Hierdurch wird die Papierbahn aufgetrennt und wird sie in weiterer Folge auf der leeren Trommel 12 aufgewickelt.As a result, the paper web is separated and it becomes in another Sequence wound on the empty drum 12.

Da mittels dieser Einrichtung das Reißband 4 nahe seinem Ende erfaßt werden kann, kann dieses in die Nähe der Oberfläche der leeren Trommel 12 bewegt werden, wodurch das Reißband 4 keine Steifigkeit aufzuweisen braucht. Hierdurch werden diejenigen Nachteile, welche steifen und daher dicken Reißbändern anhaften, vermieden.Since by means of this device the tear tape 4 is grasped near its end can be placed near the surface of the empty one Drum 12 are moved, causing the tear tape 4 no rigidity needs to show.
