Abstract

The method for splicing the end of a strip of paper (18) from a new reel (19) with the end of a second strip (2) from a reel (4) which is running out comprises compressing them between a rotating knurled surface (27) and a counter-surface (34). Excess material (54) is removed after splicing by feeding it between two rollers (14, 16) rotating at a higher speed than the main rollers. An independent claim is included for a machine for carrying out the method.

Description

Die Erfindung bezieht sich auf ein Verfahren und eine Vorrichtung zum Verbinden von Materialbahnen der tabakverarbeitenden Industrie mittels Rändeln gemäß den Oberbegriffen der Ansprüche 1 bzw. 5.The invention relates to a method and a device for connecting of webs of the tobacco processing industry by means of knurling according to the The preambles of claims 1 and 5, respectively.

Bei den Materialbahnen kann es sich bspw. um Tabakartikelumhüllungsstreifen, wie etwa Zigarettenpapierstreifen, handeln. Unter Rändeln wird hier das Verbinden von Materialbahnen durch Zusammenpressen verstanden, wobei auch eine Verspleißung, Verfalzung oder Prägung der Materialbahnen stattfindet.In the case of the material webs, it may be, for example, tobacco-wrapping strips, such as about cigarette paper strips, act. Under knurling here is the connecting of Material webs understood by compression, and also a Splicing, intercalation or embossing of the material webs takes place.

Die US 3,089,661 zeigt eine Verfahren und eine Vorrichtung der eingangs genannten Art, bei dem eine ablaufende Materialbahn mit einer neuen Materialbahn verbunden wird, indem die neue Materialbahn auf die Geschwindigkeit der ablaufenden Materialbahn unter Berücksichtigung der Masse der neuen Materialbahn und der Zugfestigkeit der neuen Materialbahn beschleunigt und mittels zweier drehbarer, neben den Materialbahnen gegenüberliegend angeordneter Spleißnocken miteinander verbunden werden, wobei die Nocken zum Spleißen mit einer Geschwindigkeit synchron zu den zu verbindenden Materialbahnen einmal um ihre Rotationsachse rotiert werden. Anschließend werden der Vorspann der neuen Bahn und der Überrest der alten Bahn mit in Reaktion auf die Bewegung der Nocken aktivierten Messern abgetrennt.Methods and devices for knurling paper webs are out of the art the technique according to the publications DE 693 00 282, DE-GM 1995 937, DE-OS 1532 203 and DE-OS 1 532 204 of the Applicant known. US 3,089,661 shows a method and a device of the type mentioned, in which a running material web is connected to a new material web by the new material web on the speed of the running material web under Considering the mass of the new material web and the tensile strength of the accelerated new material web and by means of two rotatable, in addition to the Material webs opposite arranged splice cams with each other be connected, with the cams for splicing at a speed synchronously with the material webs to be joined once around their axis of rotation be rotated. Subsequently, the opening credits of the new railway and the Remnant of the old train with activated in response to the movement of the cams Severed knives.

Aufgabe der vorliegenden Erfindung ist es, solche Verfahren und Vorrichtungen zu verbessern.The object of the present invention is to provide such methods and devices improve.

Diese Aufgabe wird erfindungsgemäß durch die Gegenstände der unabhängigen Ansprüche gelöst.This object is achieved by the objects of the independent Claims solved.

Die eingangs genannten Materialbahnen werden zumeist von Bobinen abgezogen, auf denen sie aufgewickelt sind. Bei der maschinellen Verarbeitung der Bahnen tritt bei einem bevorstehenden Leerlaufen einer Bobine das Problem auf, die ablaufende Bahn mit einer Bahn einer neuen Bobine verbinden zu müssen. Um die Verarbeitung nicht stoppen zu müssen, insbesondere wenn man ohne Speichersysteme arbeiten will, sollte dies bei laufenden Bahnen geschehen. Die Bahnen müssen daher zumindest für eine gewisse Zeit möglichst synchron und parallel zueinander laufen, um sie problemlos miteinander durch Rändeln verbinden zu können und die zulaufende neue Bahn sollte etwa die Geschwindigkeit der ablaufenden Bahn aufweisen. Bei den heute herrschenden sehr hohen Verarbeitungsgeschwindigkeiten entsteht dabei das Problem, das sowohl bei der zulaufenden neuen Bahn ein vorlaufender Überrest, ein sogenannter Vorspann, als auch bei der ablaufenden alten Bahn ein nachlaufender Überrest, auch als Restmaterial bezeichnet, jeweils nach der Verbindung der Bahnen abgetrennt werden muss.The initially mentioned material webs are usually deducted from bobbins, on which they are wound up. At the machine processing of the tracks occurs in the event of an impending emptying of a bobbin the problem is on, the expiring one To connect a train with a new Bobine train. To the Processing does not have to stop, especially if you're without Memory systems wants to work, this should be done while running lanes. The At least for a certain period of time, therefore, railways must be as synchronous as possible run parallel to each other to easily connect them by knurling to be able to and the incoming new web should be about the speed of have expiring path. In today's very high Processing speeds creates the problem, which is both in the incoming new course a leading remainder, a so-called prefix, as also at the expiring old course a trailing remnant, also as Residual referred to, each separated after the connection of the webs must become.

Die Erfindung löst dies vorteilhaft dadurch, dass die Geschwindigkeit des Überrests und die der weiter zu verarbeitenden Bahn zumindest ab dem Zeitpunkt des Verbindens der Bahnen unterschiedlich eingestellt werden. Auf diese Wiese reißt der jeweilige Überrest aufgrund der sich durch den Geschwindigkeitsunterschied an der Rändelstelle entwickelnden Zugkräfte in dem Material ab, wenn diese Zugkräfte die Zugbelastbarkeit des Materials übersteigen.The invention solves this advantageously in that the speed of the remainder and that of the further processing path at least from the time of Connecting the webs are set differently. Rip on this meadow the remainder due to the speed difference the knurling site developing tensile forces in the material when these tensile forces exceed the tensile strength of the material.

Somit werden erfindungsgemäß keine zusätzlichen Teile wie Messer oder dgl. zum Trennen der Bahnen benötigt. Es können daher auch keine derartigen Teile verschleißen oder müssen justiert werden.Thus, according to the invention no additional parts such as knives or the like Separating the tracks needed. It can therefore also no such parts wear out or need to be adjusted.

Die Vorteile der Erfindung liegen auch darin, dass ihre Realisierung einfach ist und dass wenig bewegliche Teile benötigt werden.The advantages of the invention are also that their implementation is simple and that few moving parts are needed.

Es ist bevorzugt, dass das Abtrennen des Vorspanns der neuen Bahn während und/oder nach dem Rändeln dadurch geschieht, dass der vorlaufende Überrest der neuen Bahn von einer Beschleunigungsvorrichtung schneller bewegt wird als die weiter zu verarbeitende ablaufende Bahn und als die Umfangsgeschwindigkeit der Rändelvorrichtung. Hierdurch entsteht eine erhöhte Bahnspannung in dem vorlaufenden Überrest der neuen Bahn, wenn die Verbindungs- oder Rändelvorrichtung die beiden Bahnen einklemmt. Dies führt dazu, dass der Vorspann der neuen Bahn an der Einklemm- oder Verbindungsstelle abreißt.It is preferred that the separation of the leader of the new web during and / or after the knurling is done by the leading remnant of the new web is moved faster by an accelerator than that further to be processed expiring web and as the peripheral speed of Knurling. This creates an increased web tension in the leading remnant of the new train, if the connection or Knurling device clamps the two webs. This causes the Preload of the new train at the pinch or junction breaks off.

Bei einer bevorzugten Ausführungsform des erfindungsgemäßen Verfahrens kann das Restmaterial der alten Bahn abgetrennt werden, indem kurz vom Zeitpunkt zu dem die Verbindungs- oder Rändelvorrichtung die Klemmung der beiden Bahnen wieder löst, die Bobine der bis dahin ablaufenden Bahn gebremst wird.In a preferred embodiment of the method according to the invention can The leftover material of the old railway will be separated by shortly from the time to the connecting or knurling the clamping of the two webs triggers again, the bobbin is braked the hitherto running track.

Bei der vorgenannten Verbindungs- oder Rändelvorrichtung kann es sich bspw. um eine der Vorrichtungen handeln, die in den mit der vorliegenden gleichzeitig eingereichten europäischen Patentanmeldungen "Verfahren und Vorrichtung zum Verbinden von Materialbahnen" der Anmelderin (Zeichen der Anmelderin: Hauni-Akten 2464, 2465) offenbart sind.In the aforementioned connection or knurling device, it may, for example. To one of the devices acting in the present with the present filed European patent applications "Method and device for Connecting webs of material "of the Applicant (Applicant's name: Hauni-Akten 2464, 2465).

Weitere bevorzugte Ausführungsformen der Erfindung sind in den Unteransprüchen beschreiben.Further preferred embodiments of the invention are in the subclaims describe.

Die Erfindung wird nun anhand eines Ausführungsbeispiels mit Bezug auf die begleitenden Zeichnungen näher beschrieben. The invention will now be described with reference to an embodiment with reference to the accompanying drawings described in more detail.

Die Figur 1 zeigt eine Ausführungsform der Erfindung. Bei dieser wird ein erster Zigarettenpapierstreifen 2 von einer von einem Motor M1 angetriebenen Bobine 4 über zwei Walzen 6 und 8 in Richtung einer weiteren Verarbeitung gemäß Pfeil 10 abgezogen. Bevor die Bobine 4 droht leer zulaufen, wird ein neuer Zigarettenpapierstreifen 18 von einer neuen Bobine 19 über eine Walze 20 von einem von einem Motor M2 angetriebenen Walzenpaar 12 mit Walzen 14 und 16 abgezogen. Die Bobine 19 wird von einem Motor M3 angetrieben.FIG. 1 shows an embodiment of the invention. This one becomes a first Rolls of cigarette paper 2 from a reel 4 driven by a motor M1 via two rollers 6 and 8 in the direction of further processing according to arrow 10 deducted. Before the bobbin 4 threatens to run empty, a new one Roll of cigarette paper 18 from a new bobbin 19 via a roller 20 of a driven by a motor M2 roller pair 12 with rollers 14 and 16 deducted. The bobbin 19 is driven by a motor M3.

Die Walze 20 und das Walzenpaar 12 sind so angeordnet, dass die beiden Streifen 2 und 18 zwischen den Walzen 20 und 8 gemäß Pfeil 22 parallel verlaufen. In diesem Bereich befinden sich auf beiden Seiten der parallel verlaufenden Streifen 2 und 18 Walzen 24 bzw. 26. Beide Walzen 24 bzw. 26 werden unabhängig voneinander von Motoren M4 bzw. M6 angetrieben. Die Walze 24 rotiert um eine Rotationsachse 25 und ihre Umfangsoberfläche 28 bildet eine glatte Rändelfläche 27. Die Walze 26 rotiert um eine Rotationsachse 35 und trägt auf ihrer Umfangsoberfläche 30 ein Segment 32 dessen Außenoberfläche eine Rändelfläche 34 bildet. Die Rändelfläche 34 ist mit einer nicht dargestellten Riffelung versehen, die sich bei einem Kontakt der Rändelfläche 27 mit der Rändelfläche 34 in die Bahn 2 und die mit ihr zu verbindende neue Bahn 18 einprägt und somit die Verbindung zwischen den Bahnen 2 und 18 herstellt. Der Abstand der Rotationsachsen 25 und 35 ist so gewählt, dass sich die zwischen den Segmenten 23 und 32 hindurchlaufenden zu verbindenden Bahnen 2 und 18 bei sich gegenüberliegenden Flächen 27 und 34 durch Quetschung zwischen diesen Flächen 27 und 34 miteinander verbinden.The roller 20 and the roller pair 12 are arranged so that the two strips 2 and 18 between the rollers 20 and 8 according to arrow 22 are parallel. In This area is located on both sides of the parallel strip 2 and 18 rollers 24 and 26, respectively. Both rollers 24 and 26 become independent driven by motors M4 and M6. The roller 24 rotates about one Rotation axis 25 and its peripheral surface 28 forms a smooth knurl surface 27. The roller 26 rotates about an axis of rotation 35 and carries on her Peripheral surface 30 a segment 32 whose outer surface has a knurl surface 34 forms. The knurl surface 34 is provided with a corrugation, not shown, in contact with the knurling surface 27 with the knurling surface 34 in the web 2 and memorizes the new web 18 to be connected with it and thus the connection between the tracks 2 and 18 produces. The distance of the rotation axes 25 and 35 is chosen so that between the segments 23 and 32nd passing through to be joined webs 2 and 18 in opposite Surfaces 27 and 34 by pinching between these surfaces 27 and 34 connect with each other.

Alle Motoren M1, M2, M3, M4 und M6 werden von einer schematisch angedeuteten Steuerung 55 gesteuert. Die Steuerung 55 weist einen nicht dargestellten Speicher auf, in dem die hier beschriebenen Verfahrensabläufe als ein Steuerprogramm eingespeichert sind. Ein nicht dargestellter Mikroprozessor der Steuerung 55 ruft das Steuerprogramm aus dem Speicher ab, um mittels der Motoren M1, M2, M3, M4, M6 und der später noch beschriebenen Bremse, die über in der Figur 1 als Pfeile dargestellte Leitungen aktiviert werden, die hier beschriebenen Verfahrensabläufe umzusetzen. All motors M1, M2, M3, M4 and M6 are indicated by a schematically indicated Control 55 controlled. The controller 55 has a memory, not shown in which the procedures described herein are considered a control program are stored. An unillustrated microprocessor of the controller 55 calls the control program from the memory to by means of the motors M1, M2, M3, M4, M6 and the brake described later, the over in the figure 1 as Arrows shown arrows are activated, described here Implement procedures.

Bevor die Bobine 4 gänzlich leer ist, muss der neue Zigarettenpapierstreifen 18 mit dem alten Zigarettenpapierstreifen 2 verbunden werden. Dies geschieht hier durch Rändeln. Zum Rändeln der beiden Zigarettenpapierstreifen 2 und 18 werden die zu verbindenden Bahnen 2 und 18 zwischen den Walzen 20 und 8 parallel zueinander bewegt.Before the bobbin 4 is completely empty, the new cigarette paper strip 18 must the old cigarette paper strip 2 are connected. This happens through here Knurling. To knurl the two cigarette paper strips 2 and 18 are to connecting webs 2 and 18 between the rollers 20 and 8 parallel to each other emotional.

Die Geschwindigkeit zumindest einer der beiden Walzen 24 und 26 wird so gesteuert, dass sich die Flächen 27 und 34 während der Kontaktphase zumindest annähernd synchron bewegen.The speed of at least one of the two rollers 24 and 26 is so controlled that the surfaces 27 and 34 during the contact phase at least move almost synchronously.

Die Fig. 1 stellt die beiden Flächen 27 und 34 zu einem Zeitpunkt dar, zu dem sie sich noch nicht gegenüberliegen. Wenn sie sich schließlich gegenüberliegen, bilden sie an der durch den Pfeil 50 angedeuteten Stelle eine Einklemm- oder Verbindungsstelle. An dieser Stelle klemmen die Rändelfläche 27 und die Rändelfläche 34 die Bahnen 2 und 18 derart kräftig zwischen sich ein, dass die beiden Bahnen 2 und 18 miteinander verbunden werden. Dies bedeutet jedoch auch, dass ein nicht mehr verwendbarer nachlaufender Überrest 52 der alten Bahn 2 sowie ein Vorspann 54 der neuen Bahn 18 entstehen. Sowohl der Überrest 52 als auch Vorspann 54 müssen daher abgetrennt werden, um die weitere Verarbeitung der neuen Bahn 18 gemäß Pfeil 10 nicht zu stören oder gar zu unterbrechen.Fig. 1 illustrates the two surfaces 27 and 34 at a time when they not yet facing each other. When they finally face each other, form they at the indicated by the arrow 50 point a pinching or Joint. At this point, the knurled surface 27 and the clamp Knurl surface 34, the webs 2 and 18 so strong between them that the two tracks 2 and 18 are interconnected. This means, however also that a no longer usable trailing remnant 52 of the old train 2 and a header 54 of the new web 18 arise. Both the remnant 52 as also Vorspann 54 must therefore be separated to further processing the new train 18 according to arrow 10 does not disturb or even interrupt.

Das Abtrennen des Vorspanns 54 der neuen Bahn 18 geschieht entsprechend Fig. 2a und besonders Fig. 2b dadurch, dass der Vorspann 54 spätestens zum Zeitpunkt des Gegenüberliegens der Rändelfläche 27 und der Gegenfläche 34 von den Walzen 14 und 16 etwas schneller bewegt wird als die ablaufende Bahn 2 und als die Walzen 24 und 26 mit der Rändelfläche 27 bzw. der Rändelfläche 34. Durch das beschleunigte Abziehen der von den mit geringerer Geschwindigkeit umlaufenden Walzen 24 und 26 eingeklemmten Bahn 18 entsteht eine erhöhte Bahnspannung in dem Vorspann 54, sobald die durch die Rändelfläche 27 und die Rändelfläche 34 gebildete Verbindungs- oder Rändelvorrichtung die beiden Bahnen 2 und 18 miteinander verbinden. Dies führt dazu, dass der Vorspann 54 an der Verbindungsstelle 50 zwischen den Segmenten 23 und 32 abreißt.The separation of the leader 54 of the new web 18 is done as shown in FIG. 2a and 2b particularly in that the leader 54 at the latest at the time the opposite of the knurled surface 27 and the counter surface 34 of the Rolls 14 and 16 is moved slightly faster than the expiring web 2 and as the rollers 24 and 26 with the knurl surface 27 and the knurl surface 34th By the accelerated peeling of the rotating at a lesser speed Rolling 24 and 26 clamped web 18 creates an increased web tension in the leader 54 as soon as through the knurled surface 27 and the knurl surface 34th formed connecting or knurling the two webs 2 and 18th connect with each other. This causes the leader 54 at the Joint 50 breaks between the segments 23 and 32.

Das Restmaterial bzw. der nachlaufende Überrest 52 der alten Bahn 2 wird entsprechend Fig. 2c abgetrennt, indem kurz vor dem Zeitpunkt zu dem die Verbindungs- oder Rändelvorrichtung die Klemmung der beiden Bahnen 2, 18 wieder löst, die Bobine 4 der ablaufenden Bahn 2 von der schematisch über ihr angedeuten Bremse abgebremst wird. Durch das Abbremsen der ablaufenden Bahn 2 wird in dem Überrest 52 eine erhöhte Bahnspannung oder Zugspannung erzeugt, die höher liegt, als eine Zugspannung, die von der Bahn 2 verkraftet werden kann. Somit reißt auch der Überrest 52 ab.The residual material or the trailing remnant 52 of the old web 2 is separated according to Fig. 2c, by shortly before the time to the Connecting or knurling the clamping of the two webs 2, 18th again triggers the bobbin 4 of the expiring web 2 from the schematic above it indicated brake is braked. By braking the running web 2, an increased web tension or tensile stress is generated in the remainder 52, which is higher than a tensile stress that can be absorbed by the web 2. Thus, the remnant 52 tears off.

Die Abrisslinien liegen jeweils im Bereich der von der Rändelfläche 27 und der Rändelfläche 34 gerändelten Zone der Bahnen 2 und 18, da die Bahnen 2 und 18 in diesem Bereich durch die Rändelung geschwächt sind. Sowohl das Beschleunigen des Walzenpaares 12 als auch das Abbremsen der Bobine 4 wird von der Steuerung mit Hilfe der Antriebe M1 für die Bobine 4 und M2 für das Walzenpaar 12 gesteuert.The tear lines are each in the area of the knurled surface 27 and the Knurl surface 34 knurled zone of the webs 2 and 18, since the webs 2 and 18 in this area are weakened by the knurling. Both the acceleration of the roller pair 12 and the deceleration of the bobbin 4 is of the Control by means of the drives M1 for the reel 4 and M2 for the reel pair 12 controlled.

Alternativ zu der zuvor beschriebenen Ausführungsform könne jegliche beliebige und bekannte Rändelvorrichtungen eingesetzt werden, insbesondere wird auf die obengenannten parallelen europäischen Patentanmeldungen der Anmelderin verwiesen, in denen diese Ausführungsformen genauer beschrieben sind.As an alternative to the previously described embodiment, any desired and known knurling devices are used, in particular is on the above-mentioned parallel European patent applications of the applicant referenced, in which these embodiments are described in more detail.
