Abstract

Vorrichtung zur Führung einer Papierbahn Gegenstand der Erfindung ist eine Vorrichtung mit einem auf einem Bolzen (2) verdrehbar befestigten Plättchen (1), das mit einem muldenförmigen Einlauf (3) und mit einem U-förmigen Auslauf (4) versehen ist, über welche die Papierbahn (7) läuft.The invention relates to a device with a plate (1) rotatably mounted on a bolt (2), which is provided with a trough-shaped inlet (3) and with a U-shaped outlet (4), via which the Paper web (7) is running.

Description

Die Erfindung betrifft eine Vorrichtung zur Führung einer Papierbahn, insbesondere einer von einer Bobine abgewickel­ten Zigarettenpapierbahn bei der Zigarettenherstellung.The invention relates to a device for guiding a paper web, in particular a cigarette paper web unwound from a bobbin in cigarette manufacture.

Von der Bobine abgewickelte Zigarettenpapierbahnen werden in die sog. Formatmulde geführt, in der sie die vorbereitete Tabakfüllung zur Ausbildung eines Zigarettenstrangs umhül­len. Die Papierbobinen sind nicht immer vollkommen in der­selben Ebene aufgewickelt, so daß es zu axialen Verschie­bungen der Papierbahn und folglich zu Ungenauigkeiten bei ihrer weiteren Bearbeitung kommt. Bekannte Einrichtungen enthalten z. B. eine längliche flache Mulde, welche die Papierbahn durchläuft. Die Muldenränder oberhalb der Füh­rungsfläche sind zurückgebogen, damit eine teilweise ge­schlossene Führungsmulde entsteht. Die axiale Einstellung der durchlaufenden Papierbahn wird durch die seitliche Verschiebung der Mulde mit Hilfe von Stellschrauben durch­ geführt. Ferner werden zum Lageausgleich der durchlaufenden Papierbahn auch Führungsrollen verwendet, auf deren Ober­fläche eine Mulde zur Lageorientierung der durchlaufenden Papierbahn ausgebildet ist. Schließlich kann zur Lageorien­tierung die von der Bobine abgewickelte Papierbahn mittels Führungsrollen um 90° gedreht und gleichzeitig in der Ma­schine um einen rechten Winkel gedreht werden, so daß die Bobinenachse in der Maschine in Richtung der einer Format­mulde zugeführten Papierbahn verläuft. Mit den bekannten Ausrichtungsmaßnahmen läßt sich eine genaue Korrektur der Lageorientierung während des Betriebs nicht oder nur mit einem hohen technischen Aufwand durchführen.Cigarette paper webs unwound from the bobbin are guided into the so-called format trough, in which they encase the prepared tobacco filling to form a cigarette rod. The paper bobbins are not always wound completely in the same plane, so that there are axial displacements of the paper web and consequently inaccuracies in its further processing. Known facilities contain e.g. B. an elongated flat trough which passes through the paper web. The trough edges above the guide surface are bent back to create a partially closed guide trough. The axial adjustment of the continuous paper web is carried out by the lateral displacement of the trough with the help of set screws guided. Furthermore, guide rollers are also used to compensate for the position of the continuous paper web, on the surface of which a trough is formed for the orientation of the position of the continuous paper web. Finally, for orientation, the paper web unwound from the bobbin can be rotated by 90 ° by means of guide rollers and at the same time rotated through a right angle in the machine, so that the bobbin axis in the machine runs in the direction of the paper web fed to a format trough. With the known alignment measures, an exact correction of the positional orientation during operation cannot be carried out or can only be carried out with a high technical outlay.

Aufgabe der Erfindung ist es, eine die Nachteile des Standes der Technik vermeidende Einrichtung zur Führung einer Pa­pierbahn zu schaffen, die selbsttätige Lagekorrekturen der laufenden Papierbahn auf technisch einfache Weise ohne manuelle Eingriffe ermöglicht.The object of the invention is to provide a device for guiding a paper web which avoids the disadvantages of the prior art and which enables the position of the running paper web to be automatically corrected in a technically simple manner without manual intervention.

Die Einrichtung zur Führung der Papierbahn gemäß der Erfin­dung ist durch das Plättchen gebildet, das in der Mitte der Fläche auf dem Bolzen untergebracht ist und auf dessen zwei gegenüberliegenden Seiten auf der entgegengesetzten Fläche der Durchgang für die Papierbahn durch den Eintritts­schieber in der Gestalt der Mulde und den Austrittsschieber ausgebildet ist, der durch die Wand mit dem U-förmigen Ausschnitt gebildet ist, bzw. der Durchgang für die Papier­bahn durch den Eintrittsschieber und den Austrittsschieber in der Form der Mulde gebildet ist. Die Entfernung der vertikalen Kanten des Ausschnitts des Austrittsschiebers ist gleich der Breite der Papierbahn vermindert um 8 bis 12 % der Breite der Papierbahn. Der Bolzen, auf welchem das Plättchen untergebracht ist, ist in dem Halter drehbar gelagert, bzw. ist der Bolzen, auf welchem das Plättchen untergebracht ist, in dem Halter fest gelagert.The device for guiding the paper web according to the invention is formed by the plate which is accommodated in the middle of the surface on the bolt and on its two opposite sides on the opposite surface the passage for the paper web through the inlet slide in the shape of the trough and the outlet slide is formed, which is formed by the wall with the U-shaped cutout, or the passage for the paper web is formed by the inlet slide and the outlet slide in the form of the trough. The removal of the vertical edges of the cutout of the exit slide is equal to the width of the paper web, reduced by 8 to 12% of the width of the paper web. The bolt on which the plate is housed, is rotatably mounted in the holder, or the bolt on which the plate is housed is fixedly mounted in the holder.

Der Vorteil der erfindungsgemäßen Einrichtung liegt vor allem darin, daß mittels einer einfachen Einrichtung die Bewegung der Papierbahn laufend regulierbar ist, besonders in dem Falle, wenn die Scheibe der Bobine in der senkrech­ten Richtung auf die Achse nicht gerade ist, was als Fol­gerung die axial gewellte Bewegung der Papierbahn aufweist, so daß Störungen auf den weiteren Mechanismus der Zigaret­tenmaschine entstehen. Bei der Anwendung der Einrichtung gemäß der Erfindung ist nicht notwendig die Bewegung der Papierbahn gemäß dem Bedarf, z. B. durch Regulationsschrau­ben zu regulieren, aber die Regulation wird durch die eigene Einrichtung ohne den Bedienungseingriff laufend durchge­führt.The advantage of the device according to the invention lies primarily in the fact that the movement of the paper web can be regulated continuously by means of a simple device, especially in the case when the disk of the bobbin is not straight in the vertical direction on the axis, which in turn means the axially undulated Movement of the paper web has, so that disturbances arise on the further mechanism of the cigarette machine. When using the device according to the invention, the movement of the paper web according to the need, e.g. B. to regulate by regulating screws, but the regulation is carried out continuously by the own device without the operator intervention.

Die Einrichtung zur Führung und Formung einer Papierbahn 7 enthält ein rechteckiges Plättchen 1, das mit seinem Mittelteil auf einem Bolzen 2 befestigt ist. Auf der dem Bolzen 2 gegenüberliegenden Fläche des Plättchens 1 sind an den Stirnenden zwei nach oben ragende Schieber 3, 4 zur Führung der Papierbahn 7 befestigt. Der an der Einlauf­seite der Bewegung der Papierbahn 7 angeordnete Einlauf­schieber 3 ist als Mulde ausgebildet. Der an der Austritts­seite der Papierbahn angeordnete Auslaufschieber 4 ist ein U-Profil, dessen Mittelsteg am Plättchen 1 befestigt ist und dessen beide Schenkel vertikal nach oben ragen. Der Bolzen 2 ist in einem Halter 5 drehbar, wie in Fig. 3 gezeigt, oder fest in einer Klemme gelagert, um eine Verdrehung des Plättchens 1 gegenüber der Achse der durch­laufenden Papierbahn zu ermöglichen.The device for guiding and shaping a paper web 7 contains a rectangular plate 1, which is fastened with its middle part on a bolt 2. On the face of the plate 1 opposite the bolt 2, two upwardly projecting sliders 3, 4 for guiding the paper web 7 are attached to the ends. The inlet slide 3 arranged on the inlet side of the movement of the paper web 7 is designed as a trough. The outlet slide 4 arranged on the outlet side of the paper web is a U-shaped profile, the central web of which is attached to the plate 1 and the two legs of which project vertically upward. The pin 2 can be rotated in a holder 5, as shown in FIG. 3, or is fixedly mounted in a clamp in order to enable the plate 1 to be rotated with respect to the axis of the continuous paper web.

Die aus der Bobine abgewickelte und zu den Bearbeitungs­mechanismen der Zigarettenmaschine geführte Papierbahn 7 wird beim Durchlaufen der erfindungsgemäßen Führung im muldenförmigen Einlaufschieber 3 längsgewölbt und zu einer bogenförmigen Mulde geformt. Weiter läuft die Papierbahn 7 durch den U-förmigen Auslaufschieber 4 zwischen dessen vertikalen Schenkeln durch, deren Zwischenabstand kleiner als die Breite der Papierbahn 7 ist, und zwar um etwa 8 bis 12 %, vorzugsweise 10 % der Breite der Papierbahn 7.The paper web 7 unwound from the bobbin and guided to the processing mechanisms of the cigarette machine is arched lengthwise in the trough-shaped inlet slide 3 as it passes through the guide according to the invention and formed into an arcuate trough. The paper web 7 also runs through the U-shaped outlet slide 4 between its vertical legs, the spacing between which is smaller than the width of the paper web 7, namely by about 8 to 12%, preferably 10%, of the width of the paper web 7.

Falls durch eine Fehlstellung der Bobine die Papierbahn 7 nicht mit ihrer Längsachse durch die Mitte des Bolzens 2 läuft, schwenkt durch die drehbare Lagerung des Bolzens 2 im Halter 5 die Einlaufseite des Plättchens 1 mit dem muldenförmigen Einlaufschieber 3 um den Drehbolzen 2, und die Papierbahn 7 läuft zwischen den vertikalen Schenkeln des Auslaufschiebers 4 durch die Führungseinrichtung in der gewünschten Ausrichtung zu den folgenden Bearbeitungs­einheiten der Maschine.If, due to a misalignment of the bobbin, the paper web 7 does not run with its longitudinal axis through the center of the pin 2, the pivoting mounting of the pin 2 in the holder 5 pivots the inlet side of the plate 1 with the trough-shaped inlet slide 3 around the pivot pin 2 and the paper web 7 runs between the vertical legs the outlet slide 4 by the guide device in the desired orientation to the following processing units of the machine.

Bei der Ausführung der Führung nach Fig. 3 ist der Bolzen 2, der das Plättchen 1 mit dem Einlaufschieber 3 und dem Auslaufschieber 4 trägt, im Halter 5, z. B. durch eine nicht dargestellte Klemme feststellbar, so daß die Mittel­achse der Führungseinrichtung sich selbsttätig auf die Achse der Papierbahn 7 einstellt und diese Stellung durch Anziehen der Klemme gesichert wird.
