Description

Die Erfindung betrifft ein Verfahren zum Betreiben einer Maschine der tabakverarbeitenden Industrie.The invention relates to a method for operating a machine of the tobacco processing industry.

Die Erfindung betrifft außerdem eine Vorrichtung zum Zuführen wenigstens eines Hüllstreifens zu einem Zuführelement, das den wenigstens einen Hüllstreifen zu einem Strang aus rauchbarem Material oder Filtermaterial der tabakverarbeitenden Industrie zuführt, wobei die Vorrichtung ein den wenigstens einen Hüllstreifen zerteilendes Trennelement umfaßt.The invention also relates to an apparatus for feeding at least one wrapping strip to a feed element which supplies the at least one wrapping strip to a strand of smokable material or filter material of the tobacco processing industry, the device comprising a separating element dividing the at least one wrapping strip.

Die Erfindung betrifft ferner ein Verfahren zur Wiederinbetriebnahme einer Strangmaschine, wobei wenigstens ein Hüllstreifen zu wenigstens einem Strang aus rauchbarem Material oder Filtermaterial der tabakverarbeitenden Industrie zugeführt wird, wobei mittels eines Strangförderers der Strang herangefördert und auf wenigstens ein den wenigstens einen Hüllstreifen tragendes Förderelement zugeführt wird, wobei Strang und Hüllstreifen zu einem Format zum fortlaufenden Umhüllen des Stranges mit dem Hüllstreifen gefördert werden. Ferner betrifft die Erfindung ein Verfahren zum Entleeren einer Strangmaschine, insbesondere einer Zigarettenstrangmaschine oder einer Filterstrangmaschine, wobei ein in einer entsprechenden Vorrichtung oder Zuführvorrichtung sich befindender Hüllstreifen zum Umhüllen eines Strangs aus rauchbarem Material oder Filtermaterial der tabakverarbeitenden Industrie wenigstens teilweise entfernt wird.The invention further relates to a method for restarting a stranding machine, wherein at least one envelope strip is supplied to at least one strand of smokable material or filter material of the tobacco-processing industry, by means of a strand conveyor conveyed the strand and is supplied to at least one of the at least one envelope strip supporting conveying element, wherein strand and enveloping strips are conveyed to a format for continuous wrapping of the strand with the enveloping strip. Furthermore, the invention relates to a method for emptying a stranding machine, in particular a cigarette rod machine or a filter rod machine, wherein an enveloping strip in a corresponding device or feeding device for wrapping a strand of smokable material or filter material of the tobacco processing industry is at least partially removed.

Aus der DE 36 00 321 C2, die der US 4,648,409 entspricht, ist eine Papierbahn-Zuführungsvorrichtung für eine Maschine zur Zigarettenherstellung bekannt. Hierbei ist eine Saugtrommel zum Fördern wenigstens einer Papierbahn zu einem Formatband vorgesehen. Mittels einer Betätigungsvorrichtung, auf der ein Messer vorgesehen ist, ist es möglich, die Papierbahn dann abzuschneiden, wenn nach einem Start der Zigarettenherstellmaschine der auf dem Zigarettenpapier aufgebrachte Aufdruck nicht mehr fehlerhaft ist. Bei dieser Vorrichtung wird also ein sogenannter Anfahrschuß bzw. der Ausschuß bei der Wiederinbetriebnahme beseitigt. Bei der Wiederinbetriebnahme bzw. beim Wiederanfahren der Maschine zur Zigarettenherstellung ist ein manueller Eingriff zum Einfädeln der Papierbahn nach einem Maschinenstillstand notwendig.From DE 36 00 321 C2, corresponding to US 4,648,409, a paper web feeding device for a cigarette making machine is known. In this case, a suction drum is provided for conveying at least one paper web to a format strip. By means of an actuating device, on which a knife is provided, it is possible to cut off the paper web if, after a start of the cigarette manufacturing machine, the printing applied to the cigarette paper is no longer faulty. In this device, therefore, a so-called startup shot or the committee is eliminated when restarting. When restarting or restarting the cigarette making machine, a manual intervention is required to thread the paper web after machine downtime.

Bei der Zigarettenstrangherstellung bzw. der Filterstrangherstellung kann es trotzdem zu dem Problem kommen, daß bei einem Beenden der Produktion von Zigarettensträngen bzw. Filtersträngen Umhüllungspapier in der Maschine verbleibt, so daß dieses im nachhinein vor Inbetriebnehmen oder Wiederinbetriebnehmen entfernt werden muß. Ferner ist es bei einem Abriß des Hüllstreifens und auch bei einer ersten Inbetriebnahme der Strangmaschine nötig, manuell den Hüllstreifen einem Zuführelement zuzuführen, so daß der Hüllstreifen zu einem Formatband und schließlich zu einem Format gefördert wird. Auch bei der genannten DE 36 00 321 C2 ist eine manuelle Zufuhr nach einer Produktionsunterbrechung notwendig.In the case of cigarette rod production or filter strand production, however, the problem may still arise that, when the production of cigarette strands or filter strands is ended, wrapping paper in the machine remains so that it must be removed afterwards before commissioning or recommissioning. Further, it is necessary in an outline of the Hüllstreifens and also at a first start-up of the stranding machine to manually supply the Hüllstreifen a feed element, so that the Hüllstreifen is conveyed to a format tape and finally to a format. Also in the aforementioned DE 36 00 321 C2 manual feed after a production interruption is necessary.

Dieses ist relativ zeitaufwendig und insbesondere bei Zweistrangmaschinen störend und führt auch zu fehlerhaften Zigarettensträngen bzw. Filtersträngen. Hierbei ist insbesondere an Betriebsunterbrechungen zu denken, nach denen regelmäßig die Hüllstreifen in entsprechende Elemente eingefädelt werden müssen. Ferner ist es nachteilig, daß bei einem nicht gewollten Riß im Hüllstreifen eine undefinierte Hüllstreifenlänge in der Maschine bei einem Stillstand dieser verbleiben kann.This is relatively time consuming and particularly disturbing in two-strand machines and also leads to faulty cigarette rods or filter strands. This is especially to think of business interruptions, after which regularly the enveloping strips must be threaded into appropriate elements. Furthermore, it is disadvantageous that in the case of an unintentional crack in the enveloping strip, an undefined envelope strip length in the machine can remain at a standstill.

Es ist Aufgabe der Erfindung, ein Verfahren zum Betreiben einer Maschine der tabakverarbeitenden Industrie anzugeben, mit dem eine Verringerung des Anfahrschußes nach einem Anhalten der Maschine ermöglicht ist.It is an object of the invention to provide a method for operating a machine of the tobacco processing industry, with a reduction of the starting shot after a stop of the machine is made possible.

Es ist ferner eine spezielle Aufgabe der Erfindung, eine Vorrichtung zum Zuführen wenigstens eines Hüllstreifens zu einem Zuführelement dergestalt weiterzubilden, daß ein sicherer Betrieb nach einer Betriebsunterbrechung bzw. einem Abriß des Hüllstreifens, insbesondere beim Wiederinbetriebnehmen, gegeben ist. Die Wiederaufnahme des Betriebs einer Strangmaschine der tabakverarbeitenden Industrie soll insbesondere mit wenig Zeitaufwand und sehr sicher geschehen. Ferner ist es eine weitere spezielle Aufgabe der vorliegenden Erfindung, ein entsprechendes Verfahren zur Wiederinbetriebnahme einer Strangmaschine und ein Verfahren zum Entleeren einer Strangmaschine, insbesondere einer Zigarettenstrangmaschine oder einer Filterstrangmaschine der tabakverarbeitenden Industrie dergestalt auszugestalten, daß diese schnell und sicher durchgeführt werden können.It is also a specific object of the invention to develop a device for supplying at least one Hüllstreifens to a feed element in such a way that a safe operation after a business interruption or a tear of the Hüllstreifens, especially when restarting, given. The resumption of the operation of a strand machine of the tobacco processing industry should happen especially with little time and very safe. It is further a further specific object of the present invention, a corresponding method for restarting a stranding machine and a method for emptying a stranding machine, in particular a cigarette rod machine or a filter rod machine of the tobacco processing industry in such a way that they can be performed quickly and safely.

Gelöst wird diese Aufgabe durch ein Verfahren zum Betreiben einer Maschine der tabakverarbeitenden Industrie, wobei wenigstens ein Hüllstreifen vorgesehen ist, der zum Umhüllen eines Strangs aus rauchbarem Material oder Filtermaterial dient, wobei der wenigstens eine Hüllstreifen auf seinem Förderweg von einem Hüllstreifenvorrat zu einer Förmateinrichtung der Maschine in wenigstens einer vorgebbaren Position fixiert wird, um anschließend von der vorgebbaren Position weitergefördert zu werden.This object is achieved by a method for operating a machine of the tobacco processing industry, wherein at least one envelope strip is provided, which serves for wrapping a strand of smokable material or filter material, wherein the at least one envelope strip on its conveying path from a Hüllstreifenvorrat to a Forming device of the machine is fixed in at least one predeterminable position to be subsequently conveyed from the predetermined position.

Der Erfindung liegt der erfindungsgemäße Gedanke zugrunde, daß zur Verringerung des Anfahrschußes ein Fixieren des Hüllstreifenvorrats bei einem Maschinenstopp bspw: in einem Störungsfall dazu führt, daß bei einem Wiederanfahren der Maschine definiert und ohne Zeitverlust durch manuelles Einfädeln des Hüllstreifens dieser wieder zur Verfügung gestellt werden kann und weitergefördert werden kann. Hierdurch ergibt sich erfindungsgemäß eine Automatisierung des Betriebs der Maschine der täbakverarbeitenden Industrie.The invention is based on the idea according to the invention that to reduce the Anfahrschußes fixing the Hüllstreifenvorrats at a machine stop, for example: in a fault leads to the fact that defined when restarting the machine and without loss of time by manually threading the Hüllstreifens this can be made available again and can be further promoted. This results according to the invention an automation of the operation of the machine of täbakverarbeitenden industry.

Im Rahmen dieser Erfindung bedeutet Fixieren auch insbesondere Halten.In the context of this invention, fixing also means holding in particular.

Wenn vorzugsweise der Schritt des Fixierens beim Anhalten wenigstens eines Teils der Maschine durchgeführt wird, wird wenig Hüllmaterial braucht.Preferably, when the step of fixing is performed upon stopping at least a part of the machine, little wrapping material is needed.

Das Fixieren geschieht hierbei vorzugsweise nach Erhalt eines Stoppsignals und/oder eines Störungssignals. Der Schritt des Weiterförderns geschieht in einer Ausführungsform der Erfindung während oder nach dem Anfahren wenigstens eines Teils bzw. des Teils der Maschine, der angehalten wurde.Fixing is preferably done after receipt of a stop signal and / or a fault signal. The step of further conveying takes place in one embodiment of the invention during or after the start of at least one part or the part of the machine which has been stopped.

Vorzugsweise wird der wenigstens eine Hüllstreifen in der Maschine, insbesondere in einer Zuführvorrichtung fixiert.Preferably, the at least one wrapping strip is fixed in the machine, in particular in a feed device.

Wenn der stromabwärts angeordnete Teil des wenigstens einen Hüllstreifens beim oder nach dem Fixieren abgetrennt wird, kann eine definierte Startposition des Hüllmaterials vorgegeben werden. Der stromabwärts angeordnete Teil des wenigstens einen Hüllstreifens ist in einer Ausführungsform der Erfindung nicht fixiert. In dem letztgenannten Fall ist es vorzugsweise vorgesehen, den stromabwärts angeordneten Teil des Hüllstreifens aus dem Förderweg zu entfernen, bevor der fixierte Teil des Hüllstreifens weitergefördert wird, so daß noch weniger Anfahrschuß erzeugt wird. Zum Weiterfördern wird dann vorzugsweise die Fixierung beendet.If the downstream part of the at least one wrapping strip is separated during or after fixing, a defined starting position of the wrapping material can be predetermined. The downstream part of the at least one wrapping strip is not fixed in one embodiment of the invention. In the latter case, it is preferably provided to remove the downstream portion of the Hüllstreifens from the conveying path, before the fixed part of the Hüllstreifens is further promoted, so that even less starting shot is generated. For further conveying the fixation is then preferably terminated.

Die Aufgabe wird ferner durch eine Vorrichtung zum Zuführen wenigstens eines Hüllstreifens zu einem Zuführelement gelöst, das den wenigstens einen Hüllstreifen zu einem Strang aus rauchbarem Material oder Filtermaterial der tabakverarbeitenden Industrie zuführt, wobei die Vorrichtung ein den wenigstens einen Hüllstreifen zerteilendes Trennelement umfaßt, die dadurch weitergebildet ist, daß ein Fixiermittel vorgesehen ist, mittels dem ein Ende des zerteilten Hüllstreifens fixierbar ist.The object is further achieved by a device for feeding at least one wrapping strip to a feed element which feeds the at least one wrapping strip to a strand of smokable material or filter material of the tobacco processing industry, the device comprising a separating element dividing the at least one wrapping strip is further developed in that a fixing means is provided, by means of which one end of the divided wrapping strip is fixable.

Die Erfindung macht sich die erfinderische Idee zu eigen, daß im Falle einer Unterbrechung der Strangproduktion der wenigstens eine Hüllstreifen, bspw. ein Hüllstreifen, oder im Falle einer Doppelstrangmaschine zwei Hüllstreifen, definiert durchtrennt wird, um dann einen Teil zu fixieren. Beim Herunterfahren der Strangmaschine kann dann der verbleibende und nicht mehr benötigte Hüllstreifenteil aus der Maschine sicher entfernt werden, wohingegen beim Wiederanfahren oder der Wiederinbetriebnahme der Strangmaschine der nicht abgeführte Teil des Hüllstreifens, der fixiert wurde, insbesondere automatisch, für die Produktion eines Strangs bzw. mehrerer Stränge Verwendung finden kann.The invention embraces the inventive idea that, in the event of interruption of the strand production, the at least one wrapping strip, for example an enveloping strip or, in the case of a double-stranding machine, two wrapping strips, is severed in a defined manner in order then to fix a part. When shutting down the stranding machine then the remaining and no longer required Hüllstreifenteil can be safely removed from the machine, whereas when restarting or recommissioning the stranding machine, the non-removed portion of the Hüllstreifens that has been fixed, in particular automatically, for the production of one strand or more Strands can be used.

Im Rahmen dieser Erfindung umfaßt der Begriff Fixiermittel auch den Begriff Halteelement oder Haltevorrichtung.In the context of this invention, the term fixing means also includes the term holding element or holding device.

Wenn in einem bevorzugten Ausführungsbeispiel je Hüllstreifen ein Trennelement vorgesehen ist, kann ein sehr schnell arbeitendes Trennelement vorgesehen sein. Vorzugsweise ist das Trennelement ein Messer. In einer alternativen Ausführungsform kann das Trennelement auch ein Laser sein, der mittels wenigstens eines optischen Elements einen fokussierten Laserstrahl auf den Hüllstreifen bringt, so daß dieser durchtrennt wird. Der fokussierte Laserstrahl kann hierbei bewegbar sein, oder als Linie aufgefächert.If, in a preferred embodiment, a separating element is provided per enveloping strip, a very rapidly operating separating element can be provided. Preferably, the separating element is a knife.

In den folgenden Figuren sind die gleichen Elementen mit denselben Bezugsziffern gekennzeichnet, so daß von einer erneuten Vorstellung jeweils abgesehen wird.In the following figures, the same elements are denoted by the same reference numerals, so that apart from a new idea.

Fig. 1 zeigt einen Teil einer Zigarettensträngmaschine in schematischer Darstellung, wobei einige Teile in einem Schnitt in einer Seitenansicht dargestellt sind.Fig. 1 shows a part of a cigarette rod machine in a schematic representation, wherein some parts are shown in a section in a side view.

Der Teil der Strangmaschine, der in Fig. 1 dargestellt ist, umfaßt insbesondere eine Zuführvorrichtung 1, mittels der ein Hüllstreifen 10 in Form eines Zigarettenpapiers von einem Hüllstreifenvorrat 17 in Form einer Bobine zunächst einem Zuführelement 11 in Form einer Umlenkrolle zuführbar ist, wobei der Hüllstreifen 10 im folgenden oberhalb eines Gegenlagers 31 in Verbindung mit einem Tabakstrang 12 gebracht wird, der mittels eines Strangförderbandes 18 in Fig. 1 von rechts nach links (in Pfeilrichtung) gefördert wird. Für eine effektive Mitnahme des Hüllstreifenanfangs hat die Anmelderin Patente erlangt, nämlich bspw. die EP 0 595 118 B1, die der US 5,361,783 entspricht. Der Offenbarungsgehalt dieser Patente soll vollumfänglich in die Offenbarung dieser Patentanmeldung aufgenommen sein. Um bei einem Anfahren bzw. der Inbetriebnahme der Maschine sicherzustellen, daß der Anfang des Hüllstreifens 10 stromabwärts der Umlenkrolle 11 von dem zugehörigen Formatband 19 und dem zugehörigen Strang 12 mitgenommen wird, wurde bei den genannten Patenten vorgeschlagen, ein Verschiebeelement vorzusehen, das oberhalb des Gegenlagers 31 angeordnet ist, und das beim Zuführen des Hüllstreifenanfangs zum Verringern des Abstandes zwischen dem Strang förderband 18 und dem Hüllstreifen 10 aktivierbar ist. Dieses Verschiebeelement ist in den Figuren nicht dargestellt.The part of the stranding machine, which is shown in Fig. 1, comprises in particular a feeding device 1, by means of a wrapping strip 10 in the form of a cigarette paper from a Hüllstreifenvorrat 17 in the form of a reel initially a feed element 11 in the form of a deflection roller can be supplied, wherein the enveloping strip 10 is brought in the following above an abutment 31 in conjunction with a tobacco rod 12, which is conveyed by means of a strand conveyor belt 18 in Fig. 1 from right to left (in the arrow direction). For an effective entrainment of the Hüllstreifenanfangs the Applicant has acquired patents, namely, for example, the EP 0 595 118 B1, corresponding to US 5,361,783. The disclosure of these patents is intended to be fully incorporated in the disclosure of this patent application. In order to ensure at start-up or commissioning of the machine that the beginning of the Hüllstreifens 10 downstream of the guide roller 11 is taken from the associated format strip 19 and the associated strand 12, has been proposed in the said patents, to provide a displacement element, which is above the abutment 31 is arranged, and when feeding the Hüllstreifenanfangs to reduce the distance between the strand conveyor belt 18 and the enveloping strip 10 is activated. This displacement element is not shown in the figures.

Nach Erreichen des Formatbandes 19, das um die Umlenkrolle 30 umgelenkt wird und einem Format 20 zum fortlaufenden Umhüllen des Stranges 12 mit dem Hüllstreifen 10 zugeführt wird, reicht die Reibkraft zwischen dem Formatband 19 und dem Hüllstreifen 10 aus, um diesen im Dauerbetrieb entsprechend zu transportieren. In Fig. 1 ist ferner in einer schematischen Schnittdarstellung in Seitenansicht die Zuführvorrichtung 1 weiter ausgeführt und zwar in Form eines Messers 13, das auf einer Befestigungsplatte 26 angebracht ist, die mittels eines Pneumatikzylinders 25 mit Stangenführung linear quer zur Förderrichtung des Hüllstreifens 10 bewegt werden kann.After reaching the format strip 19, which is deflected around the guide roller 30 and a format 20 for continuous wrapping of the strand 12 is supplied to the enveloping strip 10, the frictional force between the format strip 19 and the enveloping strip 10 is sufficient to transport this in continuous operation accordingly , In Fig. 1, the feeding device 1 is also further in a schematic sectional view in side view in the form of a knife 13, which is mounted on a mounting plate 26 which can be moved linearly transversely to the conveying direction of the Hüllstreifens 10 by means of a pneumatic cylinder 25 with rod guide.

Das Messer 13 gelangt in einen Wirkeingriff mit einer Schneidkante 22 zum Schneiden des Hüllstreifens 10, wie schematisch auch in Fig. 2 dargestellt ist. Es ist ferner ein Gegenlager 24 vorgesehen, das mit einer Feder 23 vorgespannt ist und gegen das die Andruckfläche 14 drückt. Beim Schneiden des Hüllstreifens 10 an der Schneidkante 22 wird das eine Ende des Hüllstreifens 10 mit der Andrückfläche 14 gegen eine Fläche des Gegenlagers 24 gedrückt und so der Hüllstreifen 10 gehalten. Ein Abschneiden und Fixieren des einen Endes des abgeschnittenen Hüllstreifens 10 geschieht bspw. bei Problemen mit dem Saugstrangförderer 18.The knife 13 comes into operative engagement with a cutting edge 22 for cutting the wrapping strip 10, as also schematically illustrated in FIG. It is also an abutment 24 is provided, which is biased by a spring 23 and against which the pressure surface 14 presses. When cutting the Hüllstreifens 10 at the cutting edge 22, the one end of the Hüllstreifens 10 is pressed with the pressing surface 14 against a surface of the abutment 24 and so the envelope strip 10 is held. A cutting and fixing of the one end of the cut strip 10 is done, for example. In case of problems with the Saugstrangförderer 18th

In Fig. 2 ist die Zuführvorrichtung 1 dargestellt und zwar in einem Zustand, in dem der Hüllstreifen 10 geschnitten wurde und entsprechend ein Ende 10" des Hüllstreifens 10 eingeklemmt ist. Hieran anschließend wird der obere Teil 10' des Hüllstreifens, also derjenige Teil, der oberhalb von dem Messer 13 bzw. Trennelement 13, das in diesem Ausführungsbeispiel als Messer ausgestaltet ist, abtransportiert. Anstelle des Messers 13 kann als Trennelement 13 auch eine Laservorrichtung 32 mit einer Fokussieroptik dienen. Es ist dann auf eine andere Art und Weise eine Fixierung des einen Endes des Hüllstreifens 10 zu realisieren wie bspw. durch ein Fixiermittel, das dem in den Fig. 1 bis 3 dargestellten Fixiermittel entspricht, bei dem allerdings keine Messerfunktion gegeben ist. Es kann allerdings auch ein anderes Fixiermittel wie bspw. in Fig. 4 dargestellt ist, gegeben sein. Auf dieses Fixiermittel wird im folgenden noch eingegangen.2, the feeding device 1 is shown in a state in which the wrapping strip 10 has been cut and, correspondingly, an end 10 "of the wrapping strip 10 is clamped in. Hereinafter, the upper part 10 'of the wrapping strip, that is, that part which above the knife 13 or separating element 13, which in this embodiment is designed as a knife, instead of the knife 13, a laser device 32 with a focusing optic can serve as a separating element 13. It is then in another way a fixation of the 1 to 3, but in which no knife function is provided, however, it is also possible to use another fixing means such as, for example, in FIG is to be given. This fixative will be discussed below.

Bei einem Wiederanfahren bzw. Wiederinbetriebnehmen der Strangmaschine, wird zum einen Transportluft 21 in den Kanal eingelassen, der durch den Grundkörper 27 und den Deckel 28 definiert ist. Die Transportluft 21 ist mittels Pfeilen schematisch in Fig. 3 dargestellt. Mittels dieser Transportluft wird der Hüllstreifen 10 bzw. vor diesem Förderschritt der stromaufwärtige Teil 10" des Hüllstreifens 10 in Richtung des Zuführelements 11 zugeführt bzw. gefördert. Dieses kann vollautomatisch geschehen.When restarting or recommissioning the stranding machine, on the one hand transport air 21 is introduced into the channel, which is defined by the main body 27 and the cover 28. The transport air 21 is shown schematically by arrows in Fig. 3. By means of this transport air, the enveloping strip 10 or, before this conveying step, the upstream part 10 "of the enveloping strip 10 is fed or conveyed in the direction of the feed element 11. This can be done fully automatically.

Bei einer ersten Inbetriebnahme der Strangvorrichtung bzw. bei einem Riß des Hüllstreifens stromaufwärts des Trennelements bzw. Fixiermittels, ist es notwendig, den Hüllstreifen 10 manuell in den durch den Deckel 28 und den Grundkörper 27 definierten Kanal einzuführen. Hierzu wird eine Klappe 29 geöffnet, um eine bessere Eingriffsmöglichkeit bzw. Einfädelmöglichkeit für eine Bedienperson vorzusehen.When the strand device is put into operation for the first time or when the wrapping strip is ruptured upstream of the separating element or fixing agent, it is necessary to manually insert the wrapping strip 10 into the channel defined by the lid 28 and the base body 27. For this purpose, a flap 29 is opened in order to provide a better possibility of intervention or threading possibility for an operator.

In Fig. 4 ist eine andere Ausführungsform der erfindungsgemäßen Zuführvorrichtung 1 in schematischer Schnittdarstellung in Seitenansicht dargestellt. Zum Fixieren des Wüllstreifens 10 wird Saugluft 15 durch die Saugluftbohrungen 16 geleitet, so daß eine Fixierung durch die Saugluft geschieht. Das Trennelement 13 kann in diesem Ausführungsbeispiel eine Laservorrichtung 32 mit einer Fokussieroptik 33 sein oder ein Messer 13, das allerdings in Fig. 4 nicht dargestellt ist.4, another embodiment of the feeding device 1 according to the invention is shown in a schematic sectional view in side view. For fixing the Wüllstreifens 10 suction air 15 is passed through the Saugluftbohrungen 16, so that a fixation is done by the suction air. The separating element 13 may in this embodiment be a laser device 32 with a focusing optics 33 or a knife 13, which is not shown in FIG. 4, however.

Die erfindungsgemäße Zuführvorrichtung wird nun so betrieben, daß ein Hüllstreifen 10 mittels eines Trennelements 13, 32, 33 zerteilt wird und mittels eines Fixiermittels 13, 14, 16, 24 bei einer Betriebsunterbrechung bzw. bei einem Stopp der Strangmaschine fixiert wird. Der nicht fixierte Teil des Hüllstreifens 10 wird dann aus der Maschine entfernt, indem er mit dem Formatband 19 aus der Maschine herausgefahren wird. Bei einer Wiederinbetriebnahme der Strangmaschine wird die Fixierung gelöst und der Hüllstreifen automatisch zunächst einem Zuführelement 11 zugeführt, um dann in Kontakt mit einem Zigarettenstrang 12 oder einem Filterstrang gebracht zu werden, woraufhin dann eine Zuführung zu einem Format 20 geschieht, in der um den Zigarettenstrang bzw. den Filterstrang der Hüllstreifen umwickelt wird.The feeding device according to the invention is now operated so that an envelope strip 10 by means of a Dividing element 13, 32, 33 is divided and is fixed by means of a fixing means 13, 14, 16, 24 at a stoppage or at a stop of the strand machine. The unfixed portion of the wrapper 10 is then removed from the machine by driving it out of the machine with the format tape 19. When the stranding machine is restarted, the fixing is released and the wrapping strip is automatically fed first to a feed element 11, in order then to be brought into contact with a cigarette rod 12 or a filter strand, whereupon a feed to a format 20 takes place in which the cigarette rod or cigarette rod is moved ., The filter strand of the enveloping strip is wrapped.

Das Abtrennen des Hüllstreifens kann sowohl mit kleinen als auch mit großen Schneidwinkeln erfolgen. Hierbei kann eine Linearbewegung oder eine Schwenkbewegung des Trennelements oder eine Kombination der beiden geschehen. Für den Fall eines eine Laservorrichtung mit einer Fokussieroptik umfassenden Trennelements, wird der fokussierte Laserstrahl geschwenkt oder ein Laserstrahl erzeugt, der einen linear ausgedehnten Fokus umfaßt. Das Fixieren des Hüllstreifens kann sowohl durch eine Art Klemmen oder ein Vakuum bzw. eine Saugluft oder andere Verfahren sowohl einzeln als auch in Kombination mit dem Abtrennen erfolgen. Es ist ferner möglich, das erstmalige Einfädeln des Hüllstreifens so zu gestalten, daß der Hüllstreifen durch einen Luftstrom in die Zuführvorrichtung 1 transportiert wird und dort in einer Vorbereitungsposition abgetrennt und gehalten wird, so daß mit tatsächlichem Anfahren bzw. Inbetriebnehmen der Strangmaschine ein automatisches Zuführen des Hüllstreifens geschehen kann.The separation of the Hüllstreifens can be done both with small and with large cutting angles. In this case, a linear movement or a pivoting movement of the separating element or a combination of the two can be done. In the case of a separator comprising a laser device with focusing optics, the focused laser beam is panned or a laser beam is generated comprising a linearly extended focus. The fixing of the Hüllstreifens can be done either by a kind of clamping or a vacuum or a suction or other methods both individually and in combination with the separation. It is also possible to make the first threading the Hüllstreifens so that the envelope strip is transported by an air flow in the feeder 1 and is separated and held there in a preparation position, so that with actual startup or commissioning of the stranding machine automatic feeding of the Wrapping can happen.
