- eine Verteilereinheit zum Vereinzeln von Tabakfasern und zum Bilden und Egalisieren eines Tabakstrangs,
- eine Strangeinheit zum Formen eines Zigarettenstrangs aus dem Tabakstrang durch Umhüllen des Tabakstrangs mit einem Umhüllungsstreifen wie Zigarettenpapier, der an einer Kante beleimt und anschließend überlappend verklebt wird, wonach nach er in Einzelstücke (Zigaretten einfacher oder mehrfacher Gebrauchslänge) zerschnitten wird,
- sowie zur Herstellung von Filterzigaretten eine Filteransetzeinheit, bei der meist ein Filterstab mehrfacher Gebrauchslänge in kleinere Stücke zerschnitten wird, die zwischen zwei Zigaretten abgelegt und mittels beleimten Verbindungspapiers mit diesen verbunden werden, wonach die Doppelzigaretten durch mittiges Schneiden durch die angeklebten Filterstücke in einzelne Filterzigaretten zerschnitten werden.
- a distributor unit for separating tobacco fibers and for forming and leveling a tobacco rod,
- a strand unit for forming a cigarette rod from the tobacco rod by wrapping the tobacco rod with a wrapping strip such as cigarette paper glued to an edge and then glued overlapping, followed by after being cut into individual pieces (single or multiple use-length cigarettes),
- and for the production of filter cigarettes a filter application unit, in which usually a filter rod multiple use length is cut into smaller pieces that are stored between two cigarettes and connected by glued connection paper with these, after which the double cigarettes are cut by cutting centrally through the glued filter pieces into individual filter cigarettes ,
In Folge der Manipulation großer Tabakmengen je Zeiteinheit in der Verteilereinheit und der Bildung und Bearbeitung von Zigaretten entstehen große Mengen von Tabakstaub und Kurztabakteilchen, die sich in der Maschine lose ablagern und diese allmählich zusetzen. Die erforderliche Reinigung der Maschine ist arbeits- und zeitaufwendig. Außerdem entstehen bei den geschilderten Schneidvorgängen und zusätzlich bei Beleimungsschritten (Beleimung einer Kante des Zigarettenpapiers; Beleimung eines Papierstreifens, von dem Verbindungsblättchen abgeschnitten werden) Ablagerungen. Diese bestehen aus einer klebrigen Masse aus Tabakstaub und klebrigen Soßenbestandteilen oder aus Filtermaterial und flüssigem Weichmacher oder aus Leimbestandteilen. Auch hier sind regelmäßige Reinigungsmaßnahmen erforderlich, während der die Zigarettenherstellmaschine nicht in Produktion laufen kann.As a result of the manipulation of large amounts of tobacco per unit time in the distribution unit and the formation and processing of cigarettes arise large amounts of tobacco dust and Kurztabakteilchen that loosely deposit in the machine and enforce them gradually. The required cleaning of the machine is laborious and time consuming. In addition, deposits occur in the described cutting operations and additionally in gluing steps (gluing of an edge of the cigarette paper, gluing of a paper strip from which connecting leaves are cut off). These consist of a sticky mass of tobacco dust and sticky sauce components or of filter material and liquid plasticizer or of glue components. Again, regular cleaning is required during which the cigarette maker can not run in production.
Bisher werden zur Reinigung die Maschinen geöffnet und der Staub von Hand abgesaugt. Die Bauteile mit Ablagerungen werden manuell, zum Beispiel mit einer Reinigungsflüssigkeit gereinigt.So far, the machines are opened for cleaning and the dust sucked by hand. The components with deposits are cleaned manually, for example with a cleaning fluid.
Ein manuelles Reinigen benötigt jedoch relativ viel Zeit, in welcher die zu reinigende Maschine für ein Produzieren nicht zur Verfügung steht.However, manual cleaning takes a relatively long time, in which the machine to be cleaned is not available for production.

In
Die Maschine M weist drei Hauptbestandteile auf, nämlich eine Verteilereinheit VE, eine Strangeinheit SE und eine Filteransetzeinheit FA.The machine M has three main components, namely a distributor unit VE, a string unit SE and a filter application unit FA.
In der Verteilereinheit VE wird einem Tabakvorratsbehälter 1 mittels Saugluft durch eine Rohrleitung 2 Schnitttabak zugefördert, der sich in der Maschine als Tabakvorrat 3 absetzt. Die Saugluft verlässt die Maschine durch ein Sieb 4 und eine Rohrleitung 6. Der verfilzte Tabak 3 wird in der Verteilereinheit VE vereinzelt und der Unterseite eines luftdurchlässigen Tabakstrangförderbandes 7 zugeführt, an dessen Rückseite sich eine Unterdruckkammer 8 befindet. Der Unterdruck in der Kammer 8 wird von einem Sensor 9 erfasst und von einem Unterdruck erzeugenden Ventilator 11 zumindest annähernd konstant gehalten. Die Zufuhr der Tabakfasern zu dem Strangförderband 7 wird unterstützt von einer Luftströmung 12, die von einem Ventilator 13 durch eine Leitung 14 zugeführt wird. 16 ist eine Siebanordnung zum Abscheiden von Tabakteilchen in der Zufuhrluft. An dem Strangförderband 7 baut sich unter dem Einfluss der Saugluft durch das Band 7 in Kammer 8 ein Strang 17 aus Tabakfasern auf, dessen Oberfläche ungleichmäßig ist und durch eine bekannte Egalisiervorrichtung 18 homogenisiert wird. Die Vorrichtung besteht im wesentlichen aus zwei umlaufenden Klemmscheiben, von denen nur eine (19) sichtbar ist, und einem nichtdargestellten drehenden Paddelrad, das den unter die Klemmebene nach unten ragenden Tabak abpaddelt.In the distribution unit VE a
In der Strangeinheit SE wird aus dem geglätteten Tabakstrang 17 ein Zigarettenstrang 21 geformt. Hierzu wird der Strang 17 auf einen von einer Bobine 20 abgezogenen Zigarettenpapierstreifen 22 abgelegt und mit diesem von einem Band 23 durch einen sogenannten Formatteil 24 gezogen. Der Formatteil 24 weist einen sogenannten Finger 26 auf, unter dem der Zigarettenpapierstreifen 22 fortlaufend in eine runde Form gekrümmt wird, von der eine Kante absteht. Diese wird von einer Beleimvorrichtung 27 beleimt und von einer Verschlussvorrichtung 28 auf den bereits gerundeten Zigarettenstrang 21 gedrückt. Die Leimnaht des Zigarettenstrangs 21 wird von einer Heizvorrichtung 29 getrocknet. Der Zigarettenstrang 21 wird von einer umlaufenden Messervorrichtung 30 fortlaufend in Zigaretten 31 doppelter Gebrauchslänge zerschnitten und von einer Beschleunigungsvorrichtung 32 der Filteransetzeinheit zugeführt. Einzelheiten der Beschleunigungsvorrichtung zeigt die
Auf einer Schneidtrommel 33 am Einlauf der Filteransetzeinheit FA werden die doppelt langen Zigaretten von einem drehenden Kreismesser 34 in Zigaretten einfacher Gebrauchslänge (nicht dargestellt) zerschnitten. Auf einer sogenannten Spreiztrommel 36 werden die Zigaretten axial gegeneinander verschoben, um einen Zwischenraum (nicht dargestellt) zu bilden, in den auf einer Filtereinlegetrommel 37 nicht dargestellte Filterstücke doppelter Gebrauchslänge abgelegt werden. Die Filterstücke werden auf einem sogenannten Filterapparat 38 gebildet. Hierzu werden einem Magazin 39 Filterstäbe 41 von einer Entnahmetrommel 42 entnommen und über eine Zwischentrommel 43 einer Schneidtrommel 44 mit einem drehenden Kreismesser 45 zugeführt; nach dem Schneiden und dem sogenannten Entstaffeln der Filterstücke werden diese auf der Trommel 46 als Reihe aus hintereinander angeordneten Filterstücken doppelter Gebrauchslänge (nicht dargestellt) der Trommel 37 zugefördert. Auf einer Schiebetrommel 47 werden die Zigaretten aufeinander zugeschoben, bis sie an den dazwischen liegenden Filterstücken anliegen. Auf einer Rolltrommel 48 werden beleimte nicht dargestellte Belagpapierblättchen an die Filterstücke und die Endbereiche der Zigaretten angesetzt und die Filterzigarettengruppen, jeweils gebildet von Zigaretten und einem dazwischen liegenden Filterstück, durch Rollen an einer nicht dargestellten Gegenrollfläche miteinander verbunden. Auf einer Schneidtrommel 49 werden die Gruppen durch ein rotierendes Kreismesser 51 mittig durch die Filterstücke geschnitten und so die fertigen Filterzigaretten gebildet. Nach dem Wenden einer Zigarettenreihe auf einer Wendetrommel 52 werden die Filterzigaretten auf einer Prüftrommel 53 geprüft und die fehlerhaften Zigaretten von einer Ausblastrommel 54 abgeblasen. Mit 56 ist eine Ablegertrommel bezeichnet, die die Filterzigaretten 57 auf ein Abförderband 58 übergibt, auf dem sie abgefördert werden. Die Zigaretten werden auf den Trommeln 33...56 in nicht dargestellten Mulden mittels Saugluft gehalten, die den Trommeln von einem Unterdruckraum 59 über Kanäle 61 zugeführt wird. Der Unterdruck wird von einem Ventilator 62 erzeugt. Zum Abfördern von Ausschusszigaretten und anderen ausgeschiedenen Tabak- oder Filterbestandteilen dient ein Abförderband 63, das die Teile in einen Ausschussraum 64 fördert.On a cutting
Die vorstehend beschriebene Maschine zur Herstellung von Filterzigaretten ist wie bereits erwähnt im wesentlichen bekannt. Sie kann auch ohne Filteransetzeinheit FA betrieben werden, so dass sie sogenannte Plain-Zigaretten ohne angesetzte Filter erzeugt.The above-described machine for producing filter cigarettes is substantially known as already mentioned. It can also be operated without filter application unit FA, so that it produces so-called plain cigarettes without attached filters.
Die Maschine weist mehrere Bereiche auf, in denen sich Staub und / oder Kurztabak lose ansammeln oder sich an Maschinenteilen unter dem Einfluss von Soße und Leim ablagern kann. Im zuletzt genannten Fall ist eine Beseitigung schwieriger. Bisher werden zur Reinigung die Maschinen geöffnet und der Staub von Hand abgesaugt. Die Bauteile mit Ablagerungen werden manuell, z.B. mit einer Reinigungsflüssigkeit gereinigt. Diese Arbeiten werden nach der Erfindung schneller und, falls gewünscht, automatisch durchgeführt.The machine has several areas where dust and / or short tobacco can accumulate loosely or deposit on machine parts under the influence of sauce and glue. In the latter case, elimination is more difficult. So far, the machines are opened for cleaning and the dust sucked by hand. The components with deposits are cleaned manually, eg with a cleaning fluid. This work will be faster and, if desired, carried out automatically according to the invention.
Hierzu dient ein mobiles Gerät 71, das auf Rollen 72 verfahrbar ist. Es enthält einen Zufuhrteil 73 für Luft, die mittels einer Heizung 74 erwärmbar ist und über eine Leitung 76 von einem Ventilator 77 zu einer Anschlussstelle 78 geblasen werden kann. Die Leitung 76 kann mittels einer bekannten pneumatischen Kupplung schnell anund abgekoppelt werden. In dem pneumatischen System kann ein Luftpuffer 79 vorgesehen sein. Die unter Druck stehende Luft wird zu einer im VE-Bereich angeordneten Leitung 81 z.B. einer Rohrleitung mit Auslassöffnungen (nicht dargestellt) geleitet, aus denen Luftströme 82 in Bereiche austreten können, in denen erfahrungsgemäß Staub- und Kurztabakansammlungen auftreten. Anstatt der Luft kann auch Dampf, z.B. trockener Dampf zugeführt werden.For this purpose, a mobile device 71, which is movable on
Das mobile Gerät 71 enthält außerdem einen Zufuhrteil 83 für Flüssigkeit wie Wasser, das gegebenenfalls heiß ist und sich in einem Behälter 84 befindet. Es kann von einer Pumpe 86 über eine Leitung 87 zu einer Anschlussstelle 88 gefördert werden, die eine hydraulische Kupplung zum schnellen An- und Abkoppeln der Leitung 87 aufweisen kann. Das erwärmte Wasser wird durch eine Leitung 91 z.B. eine Rohrleitung zu einer Düse gefördert, aus der es auf Ablagerungen an der Egalisatorvorrichtung 18 auftreffen und diese ablösen kann. Das Wasser der Reinigungsflüssigkeit kann mit einem Lösungsmittel versehen sein, oder es kann eine spezielle Reinigungsflüssigkeit verwendet werden. Anstelle von Flüssigkeit oder zusätzlich dazu kann Dampf, vorzugsweise feuchter Sattdampf zugeführt werden. Die Leitungen in der Maschine, durch die Flüssigkeit und / oder Dampf zugeführt werden, sind strichliert dargestellt.The mobile device 71 also includes a
Das mobile Gerät 71 enthält außerdem eine Abfördereinheit in Form einer Absaugvorrichtung 93, die an einer Anschlussstelle 94 mittels einer Leitung 95 an eine interne Leitung 92 der Maschine z.B. eine Rohrleitung an- oder abkoppelbar ist. Ein Ventilator 97 saugt aufgewirbelten Staub oder Kurztabak und / oder feuchte beladene Luft und / oder Dampf und / oder Flüssigkeit aus einer in der Maschine befindlichen Leitung 92 und kann sie, eventuell über eine Siebanordnung 98, zu einer nichtdargestellten zentralen Entstaubungsanordnung leiten.The mobile device 71 also contains a discharge unit in the form of a
Das mobile Gerät 71 lässt sich zu verschiedenen Bereichen der Maschine M bewegen und dort zur Reinigung einsetzen. So sind die Anschlussstellen 101, 102 zum Absaugen vorgesehen, Anschlussstelle 103 zum Zuführen von Luft zu einem Rohr 104, aus dem Luft 105 austritt. Von Anschlussstelle 106 kann Wasser und / oder Dampf über Leitung 107 zum dem Formatteil 24 geleitet werden, um Leimabsatz zu beseitigen. Von Anschlussstelle 108 kann über Leitung 109 Wasser und / oder Dampf zu den Kreismessern 34, 45 und 51 geleitet werden, um Ablagerungen abzulösen. Über Anschlussstelle 111 kann Luft 112, z.B. Heißluft, zu Rohrleitung 113 geleitet werden, über Anschlussstelle 114 kann Luft und / oder Feuchte von Rohrleitung 116 abgesaugt werden. Über Anschlussstelle 117 und Rohrleitung 118 kann Heißluft 119 zu der Filteransetzeinheit FA geleitet werden, die insbesondere zum Trocknen von Maschinenteilen dient, die von Flüssigkeit und / oder Dampf aus Leitung 109 benetzt worden sind. Über Anschlussstelle 121 kann Ausschuss, Kurztabak und Staub aus dem Ausschussraum 64 und einer dahinführenden Leitung 122 abgesaugt werden.The mobile device 71 can be moved to different areas of the machine M and used there for cleaning. Thus, the connection points 101, 102 are provided for suction, connection point 103 for supplying air to a
Beim Absaugen des Staubes und des Kurztabaks werden größere Absaugluftströme benötigt. Um die Luftströme in der benötigten Größe in die weitgehend abgedichtete Maschine M einzulassen, werden Ventile 123 vorgesehen, die von Hand oder automatisch geöffnet oder geschlossen werden können. Dabei werden diejenigen Ventile 123 geöffnet, die denjenigen Innenräumen der Maschine M zugeordnet sind, die mit der Absaugvorrichtung verbunden sind.When vacuuming the dust and the short tobacco, larger suction air flows are required. To admit the air flows in the required size in the largely sealed machine M,
Die Reinigungsanordnung gemäß der Erfindung kann periodisch oder nach Bedarf oder im Stillstand der Maschine M bei Pausen aktiviert werden, wobei die Luft zum aufwirbeln von Staub oder von Kurztabak intermittierend (impulsförmig) zugeführt werden kann. Der aufgewirbelte Staub oder die gelösten Ablagerungen werden dann abgesaugt und damit aus der Maschine entfernt.The cleaning arrangement according to the invention can be activated periodically or as required or at standstill of the machine M at pauses, the air for the stirring of dust or short tobacco supplied intermittently (pulsed) can be. The fluidized dust or dissolved deposits are then sucked off and thus removed from the machine.
In
Anstelle eines mobilen Gerätes 71 (
Zum Absaugen dienen steuerbare Ventile oder Klappen 131, die einzeln oder in Gruppen über Leitung 132 mit der Saugseite des Ventilators 11 verbunden werden können. In diesem Fall wird ein Ventil 133 geschlossen. Mit den einzelnen steuerbaren Ventilen oder Klappen 131 lassen sich Innenräume der Maschine M selektiv entsorgen. In ähnlicher Weise lässt sich Ausschussraum 64 über eine Leitung 136 entsorgen, wobei ein Ventil oder eine Klappe 137 geöffnet sowie ein Ventil oder eine Klappe 138 geschlossen wird.
Der Vorteil der Variante gemäß
The advantage of the variant according to
In den Figuren 4a und
Fig. 4a zeigt die Betriebsstellung des Fingers 26, wie sie in
Die Steuerung der oben geschilderten Reinigungsschritte wird vorteilhaft so ausgelegt, dass diese Schritte vorzugsweise während Betriebspausen der Maschine ausgeführt werden. Es kann dann gar nicht mehr zu größeren Staub- / Kurztabakansammlungen oder zu Ablagerungen in der Maschine kommen, deren Entfernung von Hand erheblich Zeit beansprucht. Die Betriebspausen werden also vorteilhaft automatisch zur Maschinenreinigung benutzt.The control of the above-described cleaning steps is advantageously designed so that these steps are preferably carried out during breaks in the operation of the machine. It can then no longer come to larger dust / Kurztabakansammlungen or deposits in the machine, the removal of which takes considerable time by hand. The breaks are thus advantageously automatically used for machine cleaning.
