Definitions
- the invention relates to a device for connecting two material webs according to the preamble of claim 1.
- a device for flying reel change in which a new paper web can be adhered to the running paper web of a running at production speed printing press.

- a device for flying reel change in which a cutting device and an adhesive roller are provided in a frame.
- the frame can be approximated from one side to the running paper web, so that when triggering the connecting device, an adhesive roller is pressed together with the running paper web against the splice of the new paper web. Subsequently, the running paper web is severed by the cutting blade.
- a disadvantage of the known devices for connecting two paper webs during flying reel change is that due to the arrangement of the cutting device in the conveying direction of the running web before the connecting device, such as a glue roller or brush, a so-called "flag" necessarily results.
- the length of this flag that is, the distance between the junction between the new and the old material web and the severed tail of the old material web, is substantially determined by the distance between the connecting device and the cutter. Due to the flag, faults are often caused during conveyance of the material web by a processing machine, for example a web-fed rotary printing press.
- WO 99/40004 A1 which is considered to be the closest state of the art, proposes a device in which the flag is pressed outwards by appropriate web guiding after severing the old material web due to the centrifugal forces acting on the flag and subsequently is separated by a male connector.

It should be noted, however, that if the flag length is too short, there is potentially a risk that the new material web will be injured accidentally by the cutting member.
- the cutting device is arranged behind the connecting device, there is a potential risk that the new material web will also be injured unintentionally when the old material web is severed.
- the cutting device is brought into engagement with the material web to be separated by adjusting a web guiding device, with which the web guide of the material web to be separated is changeable.
- a web guiding device with which the web guide of the material web to be separated is changeable.
- the cutting device must be arranged for separating the old material web in this case such that the old material web, after the splice has passed the cutting device, can be severed due to its trajectory by contact with the cutting edge of the cutting device.
- An advantage of this embodiment lies in particular in the fact that the cutting device does not have to be adjusted for cutting through the old material web, but can be arranged fixedly.
- the required to cut through the old material web change the web guide of the old material web can be particularly easily achieved in that the connecting device, such as a glue roll or brush, after it has pressed the expiring web to the new web, is adjusted in such a way that the old material web comes into engagement with the cutting device.
- the connecting device such as a glue roll or brush
- the cutting device As an alternative to adjusting a web guiding device with which the web guide of the material web to be separated can be changed, it is also conceivable for the cutting device to be separated by suitable adjustment of a web guiding device with which the web guide of the new material web can be changed, and simultaneous adjustment of the cutting device Material web comes into engagement.

- the connecting device 02 designed in the manner of an adhesive roller is rotatably mounted on the lower ends of the pivot arms 07.
- the cutter 03 is fixed to the frame connected to the frame 04.
- the frame 04 in turn is pivotally mounted and can be pivoted about an axis of rotation 08, which coincides with the axis of rotation of a guide roller 09, by means of a drive device, not shown.
- FIG. 1 shows the device 01 in its basic position.
- the device 01 In the basic position, the device 01 is pivoted to the right such that neither the cutting device 03 nor the connecting device 02 engages with one of the material webs.

Description
Die Erfindung betrifft eine Vorrichtung zum Verbinden zweier Materialbahnen gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a device for connecting two material webs according to the preamble of claim 1.
Aus der DE 42 18 825 A1 ist eine Vorrichtung zum fliegenden Rollenwechsel bekannt, bei der eine neue Papierbahn an die ablaufende Papierbahn einer mit Produktionsgeschwindigkeit laufenden Druckmaschine angeklebt werden kann. Nach dem Ankleben der neuen Papierbahn wird die ablaufende Papierbahn mittels einer Schneideinrichtung unter Bildung zweier Bahnenden durchtrennt, wobei das eine Bahnende zusammen mit der neuen Papierbahn durch die Druckmaschine gefördert wird und das zweite Bahnende zusammen mit der verbrauchten Papierrolle aus dem Rollenwechsler entfernt werden kann. Beim Rollenwechsel drehen sich beide Papierrollen mit gleichem Drehsinn, wobei die ablaufende Papierbahn derart an der neuen Papierrolle vorbei geführt wird, so dass der Anfang der neuen Papierbahn beim Ankleben an die ablaufende Papierbahn möglichst tangential an der ablaufenden Papierbahn zur Anlage kommt.From DE 42 18 825 A1 a device for flying reel change is known in which a new paper web can be adhered to the running paper web of a running at production speed printing press. After adhering the new paper web, the running paper web is severed by means of a cutter to form two web ends, wherein the one web end is conveyed together with the new paper web through the printing press and the second tail can be removed together with the used paper roll from the paster. When reel change both paper rolls rotate with the same direction of rotation, the running paper web is guided so past the new paper roll, so that the beginning of the new paper web comes as tangent to the running paper web when glued to the running paper web to the plant.
Aus der US 49 36 942 A ist eine Vorrichtung zum fliegenden Rollenwechsel bekannt, bei der in einem Rahmen eine Schneideinrichtung und eine Klebewalze vorgesehen sind. Beim Rollenwechsel kann der Rahmen von einer Seite aus an die ablaufende Papierbahn angenähert werden, so dass beim Auslösen der Verbindungsvorrichtung eine Klebewalze zusammen mit der ablaufenden Papierbahn gegen die Klebestelle der neuen Papierbahn gedrückt wird. Anschließend wird durch das Schneidmesser die ablaufende Papierbahn durchtrennt.From US 49 36 942 A a device for flying reel change is known in which a cutting device and an adhesive roller are provided in a frame. When changing roles, the frame can be approximated from one side to the running paper web, so that when triggering the connecting device, an adhesive roller is pressed together with the running paper web against the splice of the new paper web. Subsequently, the running paper web is severed by the cutting blade.
Aus der EP 07 20 581 B1 ist eine Vorrichtung zum fliegenden Rollenwechsel bekannt, bei der die Spannung der Papierbahn durch eine geeignete Bewegungskinematik während des Klebe- bzw. Schneidvorganges im wesentlichen konstant gehalten werden kann.From
Nachteilig an den bekannten Vorrichtungen zum Verbinden zweier Papierbahnen beim fliegenden Rollenwechsel ist es, dass aufgrund der Anordnung der Schneideinrichtung in Förderrichtung der ablaufenden Materialbahn vor der Verbindungseinrichtung, beispielsweise einer Klebewalze oder -bürste, sich zwingend eine sogenannte "Fahne" ergibt. Die Länge dieser Fahne, das heißt der Abstand zwischen der Verbindungsstelle zwischen der neuen und der alten Materialbahn und dem durchtrennten Bahnende der alten Materialbahn, wird dabei wesentlich vom Abstand zwischen der Verbindungseinrichtung und der Schneideinrichtung bestimmt. Durch die Fahne werden beim Durchfördern der Materialbahn durch eine Bearbeitungsmaschine, beispielsweise eine Rollenrotationsdruckmaschine, vielfach Störungen verursacht. Zur Vermeidung dieser Störungen wird in der WO 99/40004 A1, die als nächster Stand der Technik angesehen wird eine Vorrichtung vorgeschlagen, bei der die Fahne durch entsprechende Bahnführung nach dem Durchtrennen der alten Materialbahn aufgrund der auf die Fahne wirkenden Zentrifugalkräfte nach außen gedrückt und anschließend durch eine Messerleiste abgetrennt wird. Damit kann die Länge der Fahne auf annähernd null gekürzt werden, wobei jedoch ein erheblicher zusätzlicher Konstruktionsaufwand für eine geeignete Bahnführung und die nachgeschaltete Messerleiste erforderlich ist.A disadvantage of the known devices for connecting two paper webs during flying reel change is that due to the arrangement of the cutting device in the conveying direction of the running web before the connecting device, such as a glue roller or brush, a so-called "flag" necessarily results. The length of this flag, that is, the distance between the junction between the new and the old material web and the severed tail of the old material web, is substantially determined by the distance between the connecting device and the cutter. Due to the flag, faults are often caused during conveyance of the material web by a processing machine, for example a web-fed rotary printing press. In order to avoid these disturbances, WO 99/40004 A1, which is considered to be the closest state of the art, proposes a device in which the flag is pressed outwards by appropriate web guiding after severing the old material web due to the centrifugal forces acting on the flag and subsequently is separated by a male connector. Thus, the length of the flag can be reduced to approximately zero, but a considerable additional design effort for a suitable web guide and the downstream male connector is required.
Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung zum Verbinden zweier Materialbahnen zu schaffen.The invention has for its object to provide a device for connecting two webs.
Diese Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst.This object is achieved by the characterizing features of claim 1.
Die mit der Erfindung erzielbaren Vorteile bestehen insbesondere darin, dass durch die Anordnung der Schneideinrichtung in Förderrichtung der ablaufenden Materialbahn hinter der Verbindungseinrichtung die Fahne beim Durchtrennen der ablaufenden Materialbahn prinzipiell beliebig kurz abgeschnitten werden kann. Beim Verbinden der neuen Materialbahn mit der ablaufenden Materialbahn ergibt sich im Ergebnis immer eine Y-förmige Struktur, deren einer Ast, nämlich die alte Materialbahn ausgehend von der alten Materialrolle bis zur Klebestelle, durch die hinter der Verbindungseinrichtung angeordnete Schneideinrichtung im wesentlichen vollständig abgetrennt werden kann. Durch die Anordnung der Schneideinrichtung hinter der Verbindungseinrichtung ergibt sich im Ergebnis keine zwingende Mindestfahnenlänge, sondern die Länge der Fahne kann prinzipiell beliebig verkürzt werden. Dabei ist jedoch zu beachten, dass bei zu kurz gewählter Fahnenlänge potentiell die Gefahr besteht, dass die neue Materialbahn ungewollt durch das Schneidorgan verletzt wird.The achievable with the present invention consist in particular that by the arrangement of the cutting device in the conveying direction of the expiring web behind the connecting device, the flag when cutting the expiring web basically any short can be cut off. When connecting the new material web with the running material web results in the result always a Y-shaped structure, one branch, namely the old material web, starting from the old roll of material to the splice, can be separated by the arranged behind the connecting device cutter substantially completely , The arrangement of the cutting device behind the connecting device results in the result no mandatory minimum flag length, but the length of the flag can in principle be shortened arbitrarily. It should be noted, however, that if the flag length is too short, there is potentially a risk that the new material web will be injured accidentally by the cutting member.
Wird die Schneideinrichtung hinter der Verbindungseinrichtung angeordnet, besteht potentiell die Gefahr, dass beim Durchtrennen der alten Materialbahn auch die neue Materialbahn ungewollt verletzt wird. Um diese Gefahr zuverlässig auszuschließen, ist es besonders vorteilhaft, wenn die Schneideinrichtung durch Verstellung einer Bahnleiteinrichtung, mit der die Bahnführung der zu trennenden Materialbahn veränderbar ist, mit der zu trennenden Materialbahn in Eingriff gebracht wird. Im Ergebnis kann dadurch erreicht werden, dass die neue Materialbahn und die zu trennende Materialbahn im Bereich hinter der Klebestelle entlang unterschiedlicher Wege geführt werden, so dass zuverlässig nur die alte Materialbahn durchtrennt wird. Insbesondere lässt sich durch Verstellung der Bahnleiteinrichtung erreichen, dass die neue Materialbahn und die zu trennende Materialbahn einen bestimmten Winkel miteinander einschließen. Die Schneideinrichtung muss zum Trennen der alten Materialbahn in diesem Falle derart angeordnet werden, dass die alte Materialbahn, nachdem die Klebestelle die Schneidvorrichtung passiert hat, auf Grund ihres Bahnverlaufes durch Kontakt mit der Schneide der Schneidvorrichtung durchtrennt werden kann. Ein Vorteil dieser Ausführungsform liegt insbesondere auch darin, dass die Schneideinrichtung zum Durchtrennen der alten Materialbahn nicht verstellt werden muss, sondern feststehend angeordnet werden kann.If the cutting device is arranged behind the connecting device, there is a potential risk that the new material web will also be injured unintentionally when the old material web is severed. In order to reliably exclude this danger, it is particularly advantageous if the cutting device is brought into engagement with the material web to be separated by adjusting a web guiding device, with which the web guide of the material web to be separated is changeable. As a result, it can be achieved that the new material web and the material web to be separated are guided in the area behind the splice along different paths, so that only the old material web is reliably severed. In particular, can be achieved by adjusting the web guide that the new material web and to be separated material web include a certain angle with each other. The cutting device must be arranged for separating the old material web in this case such that the old material web, after the splice has passed the cutting device, can be severed due to its trajectory by contact with the cutting edge of the cutting device. An advantage of this embodiment lies in particular in the fact that the cutting device does not have to be adjusted for cutting through the old material web, but can be arranged fixedly.
Die zum Durchtrennen der alten Materialbahn erforderliche Änderung der Bahnführung der alten Materialbahn kann besonders einfach dadurch erreicht werden, dass die Verbindungseinrichtung, beispielsweise eine Klebewalze oder -bürste, nachdem sie die ablaufende Materialbahn an die neue Materialbahn angedrückt hat, in der Weise verstellt wird, dass die alte Materialbahn mit der Schneideinrichtung in Eingriff kommt.The required to cut through the old material web change the web guide of the old material web can be particularly easily achieved in that the connecting device, such as a glue roll or brush, after it has pressed the expiring web to the new web, is adjusted in such a way that the old material web comes into engagement with the cutting device.
Alternativ zur Verstellung einer Bahnleiteinrichtung, mit der die Bahnführung der zu trennenden Materialbahn veränderbar ist, ist es auch denkbar, dass die Schneideinrichtung durch geeignete Verstellung einer Bahnleiteinrichtung, mit der die Bahnführung der neuen Materialbahn veränderbar ist, und gleichzeitige Verstellung der Schneideinrichtung mit der zu trennenden Materialbahn in Eingriff kommt. Mit anderen Worten bedeutet dies, dass durch die Verstellung der Bahnleiteinrichtung die neue Materialbahn zumindest kurzzeitig so umgeleitet wird, dass die neue Materialbahn nach der Verstellung der Schneideinrichtung nicht mit der Schneideinrichtung in Eingriff kommt und nur die alte Materialbahn durch Verstellung der Schneideinrichtung durchtrennt wird.As an alternative to adjusting a web guiding device with which the web guide of the material web to be separated can be changed, it is also conceivable for the cutting device to be separated by suitable adjustment of a web guiding device with which the web guide of the new material web can be changed, and simultaneous adjustment of the cutting device Material web comes into engagement. In other words, this means that the new material web is at least temporarily redirected by the adjustment of the web guiding device so that the new material web does not come into engagement with the cutting device after the adjustment of the cutting device and only the old material web is severed by adjustment of the cutting device.
Um ein ungewolltes Durchtrennen der neuen Materialbahn durch die Schneideinrichtung zuverlässig auszuschließen, kann an der Schneideinrichtung ein Abstandselement vorgesehen werden, durch das ein bestimmter Mindestabstand zwischen der Schneide der Schneideinrichtung und der neuen Materialbahn gesichert wird.In order to reliably preclude unintentional severing of the new material web by the cutting device, a spacing element can be provided on the cutting device, by which a certain minimum distance between the cutting edge of the cutting device and the new material web is secured.

In Fig.1 ist eine Vorrichtung 01 mit einer in der Art einer Klebewalze ausgebildeten Verbindungseinrichtung 02, insbesondere einer Bahnleiteinrichtung, und einer in der Art eines Abschlagsmesser ausgebildeten Schneideinrichtung 03 dargestellt. Die Verbindungseinrichtung 02 und die Schneideinrichtung 03 sind beide an einem aus zwei parallel zueinander angeordneten Seitenteilen gebildeten Rahmen 04 befestigt. Zur Verstellung der Verbindungseinrichtung 02 relativ zum Rahmen 04 sind zwei um eine Rotationsachse 06 schwenkbar gelagerte Schwenkarme 07 vorgesehen. Durch Ansteuerung einer nicht dargestellten Antriebseinrichtung kann die Verbindungseinrichtung 02 um die Rotationsachse 06 drehend verschwenkt werden. Die in der Art einer Klebewalze ausgebildete Verbindungseinrichtung 02 ist dabei drehbar an den unteren Enden der Schwenkarme 07 gelagert. Die Schneideinrichtung 03 ist gestellfest mit dem Rahmen 04 verbunden. Der Rahmen 04 seinerseits ist schwenkbar gelagert und kann um eine Rotationsachse 08, die mit der Rotationsachse einer Leitwalze 09 übereinstimmt, mittels einer nicht dargestellten Antriebseinrichtung verschwenkt werden.1 shows a
Fig. 1 stellt die Vorrichtung 01 in ihrer Grundstellung dar. In der Grundstellung ist die Vorrichtung 01 derart nach rechts verschwenkt, dass weder die Schneideinrichtung 03 noch die Verbindungseinrichtung 02 mit einer der Materialbahnen in Eingriff kommt. Eine ablaufende Materialbahn 11, insbesondere einer Papierbahn, wird von einer Materialrolle 15, die in einem nicht dargestellten Rollenwechsler gelagert ist, abgespult und über die Leitwalzen 12; 09 in eine nachgeordnete Vorrichtung, beispielsweise eine Rotationsdruckmaschine, eingefördert. Die Förderrichtung der ablaufenden Materialbahn 11 ergibt sich dabei aus dem Bewegungspfeil 13.FIG. 1 shows the
Ist die alte Materialrolle 15 weitgehend erschöpft und soll deshalb ein fliegender Rollenwechsel durchgeführt werden, wird eine neue Materialrolle 14, auf der eine neue Materialbahn 16, insbesondere eine Papierbahn, aufgespult ist, im nicht dargestellten Rollenwechsler aufgespannt und gemäß dem Bewegungspfeil 17 solange rotatorisch beschleunigt, bis die Umfangsgeschwindigkeit des Bahnanfangs 18 der neuen Materialbahn 16 mit der Fördergeschwindigkeit der ablaufenden Materialbahn 11 übereinstimmt. Um die neue Materialbahn 16 mit der ablaufenden Materialbahn 11 verbinden zu können, sind am Bahnanfang 18 der neuen Materialbahn 16 Klebeetiketten 19 angebracht. Mittels eines lediglich schematisch dargestellten Sensors 21 kann das Passieren der Klebeetiketten 19 detektiert und an die Steuerung des Rollenwechslers weitergeleitet werden. Sobald die neue Materialrolle 14 die erforderliche Umfangsgeschwindigkeit erreicht hat, kann der Rahmen 04 entsprechend dem Bewegungspfeil 22 nach links verschwenkt werden, um die ablaufende Materialbahn 11 zunächst an die neue Materialrolle 14 anzunähern.If the old roll of
In Fig. 2 ist die Vorrichtung 01 nach Verschwenken des Rahmens 04 zur Annäherung der ablaufenden Materialbahn 11 an die neue Materialrolle 14 dargestellt. Bei der Schwenkbewegung des Rahmens 04 werden die Schwenkarme 07 ebenfalls verschwenkt, ohne sich selbst relativ zum Rahmen 04 zu bewegen. Im Ergebnis kommt dadurch die Verbindungseinrichtung 02 an einer Seite der ablaufenden Materialbahn 11 zur Anlage und drückt mit zunehmendem Schwenkwinkel des Rahmens 04 die ablaufende Materialbahn 11 immer weiter in Richtung der neuen Materialrolle 14. Da die Schwenkarme 07 bis dahin nicht verstellt werden, ist aufgrund der relativen Anordnung zwischen Schneideinrichtung 03 und Verbindungseinrichtung 02 eine Verletzung der ablaufenden Materialbahn 11 durch die rahmenfest montierte Schneideinrichtung 03 zuverlässig ausgeschlossen.In Fig. 2, the
Ist die Verbindungseinrichtung 02 durch Verschwenken des Rahmens 04 ausreichend nah an die neue Materialrolle 14 angenähert, kann mit der eigentlichen Verbindung der ablaufenden Materialbahn 11 mit der neuen Materialbahn 16 begonnen werden. Dazu wird vom Sensor 21 beim Passieren der Klebeetiketten 19 ein Signal an die Steuerung weitergegeben, wobei die Steuerung nach Erhalt dieses Signals die Antriebseinrichtung zu Verstellung der Schwenkarme 07 ansteuert, so dass die Schwenkarme 07 entsprechend dem Bewegungspfeil 23 nach links verschwenkt werden und dabei die ablaufende Materialbahn 11 soweit mitnehmen, bis die ablaufende Materialbahn 11 genau im Moment des Passierens der Klebeetiketten 19 an der neuen Materialrolle 14 zur Anlage kommt und dadurch der Bahnanfang 18 der neuen Materialbahn 16 mit der einen Seite der alten ablaufenden Materialbahn 11 verbunden wird.If the connecting
Der Zustand der Vorrichtung 01 genau im Moment der Verbindung zwischen ablaufender Materialbahn 11 und neuer Materialbahn 16 ist in Fig. 3 schematisch dargestellt. Man erkennt, dass sich durch die Verbindung der neuen Materialbahn 16 an einer Seite der ablaufenden Materialbahn 11 eine Y-förmige Struktur ergibt, von deren drei Ästen zwei von der ablaufenden Materialbahn 11 und einer von der neuen Materialbahn 16 gebildet werden und in deren Wurzeln sich die Klebetiketten 19 befinden. Ein ungewolltes Durchtrennen der ablaufenden Materialbahn 11 zu diesem Zeitpunkt wird dadurch ausgeschlossen, dass sich die Schneideinrichtung 03 aufgrund ihrer Anordnung am Rahmen 04 im wesentlichen parallel zur Bahnführung der ablaufenden Materialbahn 11 im Bereich des Rahmens 04 erstreckt. Außerdem ist an der Schneideinrichtung 03 ein kreisförmiges Abstandselement 24 vorgesehen, durch das ein bestimmter Mindestabstand zwischen der ablaufenden Materialbahn 11 und der Schneide der Schneideinrichtung 03 gesichert wird.The state of the
Zum Abschluss des fliegenden Rollenwechsels muss die alten Materialbahn 11, die bis dahin die ablaufende Materialbahn 11 dargestellt hat, durchtrennt werden. Um die alte Materialbahn 11 ohne Gefahr der Verletzung der neuen Materialbahn 16 durchtrennen zu können, werden die Schwenkarme 07 derart angesteuert, dass sie gemäß dem Bewegungspfeil 26 nach rechts zurück geschwenkt werden. Durch diese Schwenkbewegung wird der Bahnverlauf der alten Materialbahn 11 im Bereich hinter der Klebestelle verändert, so dass die neue Materialbahn 16 und die alte Materialbahn 11 im Bereich der Klebestelle in Abhängigkeit vom Stellwinkel der Schwenkarme 07 einen bestimmten Winkel α (Fig. 4) miteinander einschließen.To complete the flying reel change, the
In Fig. 4 ist die Vorrichtung 01 gerade im Moment des Passierens der Klebeetiketten 19 an der Schneidvorrichtung 03 dargestellt. Die Schwenkarme 07 sind zu diesem Zeitpunkt soweit zurückgeschwenkt, dass die Verbindungseinrichtung 02 gerade noch an der alten Materialbahn 11 anliegt. Die neue Materialbahn 16 verläuft straff zwischen den Klebeetiketten 19 und der neuen Materialrolle 14. Sobald die Klebeetiketten 19 die Schneideinrichtung 03 passieren, wird die alte Materialbahn 11 aufgrund ihres Bahnverlaufes von der Schneideinrichtung 03 durchtrennt, wobei die dabei entstehende Fahne gerade so lang ist, wie es sich aus dem Abstand zwischen der Schneide der Schneidvorrichtung 03 und neuer Materialbahn 16 ergibt.In Fig. 4, the
Anschließend wird die neue Materialbahn 16 in die nachgeordnete Vorrichtung 01 eingefördert und die alte Materialrolle 11 zusammen mit dem abgeschnittenen Bahnende aus dem Rollenwechsler entfernt. Außerdem wird der Rahmen 04 gemäß dem Bewegungspfeil 27 zurück in seine in Fig. 1 dargestellte Grundstellung verschwenkt.Subsequently, the
