Abstract
Description
Die Erfindung betrifft eine Vorrichtung zum Aufbauen eines kontinuierlichen Tabakstranges, mit einem entlang einer Aufbaustrecke mit einer Saugkammer in Wirkverbindung stehenden Saugstrangförderer, welcher im Strangeinlaufbereich einer den Tabakstrang zu einem umhüllten Zigarettenstrang formenden Formateinrichtung um eine mit dem Saugstrangförderer umlaufende Preßscheibe herumgeführt ist.The invention relates to a device for building a continuous Tobacco rod, with a along a construction line with a suction chamber in Actively connected suction line conveyor, which is in the line inlet area a format device forming the tobacco rod into a wrapped cigarette rod passed around a press disk rotating with the suction strand conveyor is.
Zum Herstellen eines Zigarettenstrangs werden gewöhnlich vereinzelte und aufgelockerte
Tabakfasern auf einem in einem Tabakkanal umlaufenden Strangförderer
in Form eines Endlos-Förderbandes zu einem Faserstrang aufgeschauert, der kontinuierlich
aus dem Strangaufbaubereich abgefördert und egalisiert wird, bevor er
auf einen mit einem umlaufenden Formatband in eine Formateinrichtung bewegten
Hüllmaterialstreifen abgelegt und in der Formateinrichtung mit dem Hüllmaterialstreifen,
zum Beispiel einem Zigarettenpapierstreifen, umhüllt wird. Der im Einlaufbereich
der Formateinrichtung zunächst noch eben einlaufende Hüllmaterialstreifen
wird beim Durchgang durch die Formateinrichtung zunächst U-förmig um den
Faserstrang geformt, bevor er ganz um den Strang herumgelegt und zur Bildung
einer zylindrischen Hülle entlang einer Überlappungsnaht in der Regel durch Verkleben
um den Strang herum geschlossen wird.
Als Strangförderer wird gewöhnlich ein luftdurchlässiges Gewebeband eingesetzt,
in dem sich durch den angelegten Unterdruck oder infolge des mechanischen
Drucks beim Komprimieren des Faserstrangs Tabakpartikel aus dem Strang festsetzen
und an anderer Stelle wieder ablösen können, so daß eine ordnungsgemäße
Übergabe aller Teilchen des Strangs in die Formateinrichtung verhindert
wird. Um sicherzustellen, daß alle Teilchen des Strangs, auch solche, die sich am
Strangförderer festgesetzt haben, in die Formateinrichtung abgegeben werden,
weist diese an ihrem Einlaufende eine Vorrichtung zum Abstreifen von Tabakteilchen,
einen sogenannten Schaber, auf Dieser besteht aus einem Grundkörper und
weist eine Abstreifkante auf, die dicht an der Oberfläche des Strangförderers positioniert
ist und die Tabakteilchen des Strangs vom Strangförderer abstreift.
Um die kritische Übergabezone des Tabakstranges vom oberen Saugstrangförderer
auf den mit dem Formatband zugeführten unteren, in das Format einlaufenden Zigarettenpapierstreifen
zu entschärfen, sollte sie möglichst kurz bemessen sein bzw.
sich möglichst dicht am Formateinlauf erstrecken.
Gute Ergebnisse werden mit einer möglichst kleinen, den Saugstrangförderer umlenkenden
Preßscheibe erzielt, die einerseits hohe Fliehkräfte zur besseren Ablösung
des Tabakstranges erzeugt und andererseits eine optimale Anstellung und
Ausbildung eines dem Saugstrangförderer zugeordneten Schabers erlaubt.To produce a cigarette rod, individualized and loosened tobacco fibers are usually piled up on a rod conveyor in the form of an endless conveyor belt rotating in a tobacco channel to a fiber strand which is continuously conveyed out of the strand building area and equalized before it is moved onto a belt with a circulating format belt into a format device The wrapping material strip is deposited and wrapped in the format device with the wrapping material strip, for example a cigarette paper strip. The wrapping material strip, which is initially just arriving in the infeed area of the format device, is first shaped U-shaped around the fiber strand as it passes through the format device before it is completely wrapped around the strand and, to form a cylindrical sheath along an overlap seam, generally by gluing around the strand is closed.
An air-permeable fabric belt is usually used as the strand conveyor, in which tobacco particles from the strand can adhere and detach at another point due to the negative pressure applied or due to the mechanical pressure when the fiber strand is compressed, so that a proper transfer of all particles of the strand into the format device is prevented. In order to ensure that all particles of the strand, including those that have attached themselves to the strand conveyor, are released into the format device, this device has a device for stripping tobacco particles, a so-called scraper, at its inlet end. This device consists of a base body and has one Scraper edge, which is positioned close to the surface of the strand conveyor and wipes the tobacco particles of the strand from the strand conveyor.
In order to defuse the critical transfer zone of the tobacco rod from the upper suction line conveyor to the lower cigarette paper strips that are fed into the format with the format belt, it should be as short as possible or extend as close as possible to the format inlet.
Good results are achieved with the smallest possible pressing disk deflecting the suction line conveyor, which on the one hand generates high centrifugal forces for better detachment of the tobacco rod and on the other hand allows optimal adjustment and formation of a scraper assigned to the suction line conveyor.
Hingegen ist eine relativ eng bemessene Bandumlenkung extrem empfindlich gegen den in diesem Bereich zwangsläufig anfallenden Tabakstaub, der zerstörend auf die Lagerung einer derartigen Preßscheibe einwirkt und sich auf der Scheibenumfangsfläche ablagert, so daß das Förderband abgehoben wird und durch den Schaber zerstört werden kann. On the other hand, a relatively narrow belt deflection is extremely sensitive against the tobacco dust that inevitably arises in this area, which is destructive acts on the bearing of such a press washer and on the disk peripheral surface deposits, so that the conveyor belt is lifted and by the Scraper can be destroyed.
Der Versuch, durch die Anstellung eines Schabers Staubablagerungen von der Scheibenumfangsfläche zu entfernen, hat zu keinen befriedigenden Ergebnissen geführt.Trying to remove dust from the dust by placing a scraper Removing the peripheral surface of the pane has unsatisfactory results guided.
Der Erfindung liegt die Aufgabe zugrunde, die Funktionssicherheit einer derartigen im Hinblick auf eine bessere Strangbildung optimierten Bandumlenkung sowie deren Standzeit zu erhöhen.The invention has for its object the functional reliability of such with regard to a better strand formation optimized belt deflection as well to increase their service life.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Preßscheibe im Bereich
eines umschlingungsfreien Umfangsabschnitts durch einen einerseits mit dem
inneren Lagerraum der Preßscheibe und andererseits mit der Saugkammer in
Strömungsverbindung stehenden Luftkanal begrenzt ist.
Auf diese Weise wird die Preßscheibe gleichermaßen an allen inneren und äußeren
staubablagernden Flächen durch einen permanent wirkenden Saugzug gereinigt.
Die inneren Flächen werden durch den Saugzug gemäß einer Weiterbildung am
besten dadurch erreicht, daß die Strömungsverbindung zum Lagerraum der Preßscheibe
durch beidseitig am Umfangsrand der Preßscheibe austretende Luftschlitze
hergestellt wird, welche zweckmäßigerweise in Form von wenigstens acht Radial-Randschlitzen
ausgebildet sind.
Gewöhnlich ist das Förderband kurz vor seinem Umlauf um die Preßscheibe an
einem feststehenden Schubstreckenklotz entlanggeführt, welcher gemäß einer
Weiterbildung dazu genutzt wird, den Luftkanal durch eine Ausnehmung in dem den
Saugstrangförderer führenden Schubstreckenklotz zu bilden.
Die Effektivität des Luftkanals wird gemäß einer Weiterbildung dadurch optimiert,
daß er seitlich durch als Messerleisten ausgebildetete Seitenwände begrenzt ist,
welche Durchbrechungen aufweisen, die den Luftkanal mit der Atmosphäre verbinden. This object is achieved according to the invention in that the pressure disk is delimited in the region of a wrap-free circumferential section by an air channel which is in flow connection on the one hand with the inner storage space of the pressure disk and on the other hand with the suction chamber.
In this way, the pressure plate is cleaned equally on all inner and outer dust-depositing surfaces by a permanent suction. The inner surfaces are best achieved by the suction according to a further development in that the flow connection to the storage space of the pressure plate is established by air slots emerging on both sides at the peripheral edge of the pressure plate, which are expediently designed in the form of at least eight radial edge slots.
The conveyor belt is usually guided shortly before it rotates around the pressure disk along a fixed thrust block, which according to a further development is used to form the air channel through a recess in the thrust block leading the suction line conveyor.
According to a further development, the effectiveness of the air duct is optimized in that it is laterally delimited by side walls designed as knife strips, which have openings which connect the air duct with the atmosphere.
Eine noch effektivere Stauberfassung und Staubabsaugung wird nach einem weiteren
Vorschlag dadurch erreicht, daß der Schubstreckenklotz unterhalb der in den
Luftkanal einmündenden Durchbrechungen der Seitenwände mit einem in den zwischen
dem unteren Umfangsabschnitt der Preßscheibe und dem Saugstrangförderer
gebildeten Zwickel eingreifenden schaberartigen Partikel-Rückhaltekeil versehen
ist.
Eine definierte Entstaubungszone wird nach einem weiteren Vorschlag dadurch
erreicht, daß der im wesentlichen konzentrisch zur Preßscheibe verlaufende Luftkanal
sich zwischen dem unteren Rückhaltekeil des Schubstreckenklotzes und
einem oberen mit dem Schubstreckenklotz verbundenen, gegen die Preßscheibe
angestellten Schaber erstreckt. Die Entstaubung des Lagerraumes der Preßscheibe
wird noch dadurch erleichtert, daß die Stirnflächen der Preßscheibe Durchbrechungen
aufweisen.An even more effective dust collection and dust extraction is achieved according to a further proposal in that the thrust link block below the openings in the air duct opening in the side walls is provided with a scraper-like particle retention wedge which engages between the lower peripheral portion of the press disk and the suction line conveyor.
According to a further proposal, a defined dedusting zone is achieved in that the air duct, which runs essentially concentrically to the pressure plate, extends between the lower retaining wedge of the thrust block and an upper scraper connected to the thrust block and placed against the pressure plate. The dedusting of the storage space of the press disk is further facilitated in that the end faces of the press disk have openings.
Der mit der Erfindung erzielte Vorteil besteht darin, daß durch eine permanente Entstaubung bzw. Staubfreihaltung der besonders sensiblen Funktionsbereiche, insbesondere der Lagerstellen und der Bandführungsfläche der Preßscheibe, einerseits deren Betriebssicherheit im Vollastbetrieb langfristig erhalten bleibt und damit einhergehend langfristig auch eine sichere Bandführung und somit eine Erhöhung der Bandstandzeit gewährleistet ist. The advantage achieved with the invention is that by a permanent Dedusting or keeping the particularly sensitive functional areas free of dust, especially the bearing points and the belt guide surface of the press disk, on the one hand, their long-term operational safety is maintained in full load operation and along with this, in the long term, secure tape guidance and thus one Increasing the belt life is guaranteed.

In Figur 1 ist der Formateinlauf einer Zigarettenstrangmaschine dargestellt. Sie
zeigt das Abgabeende eines als luftdurchlässiges Endlos-Förderband ausgbildeten
Saugstrangförderers 1 und einen Teil einer Formateinrichtung 2 mit einem strichpunktiert
angedeuteten Formatbett 3 und einem Einlauffinger 4. Der Saugstrangförderer
1 läuft in Pfeilrichtung 6 in einem Tabakkanal 7 um und fördert einen Faserstrang
aus Tabakfasern (nicht dargestellt) von einer Strangaufbauzone (ebenfalls
nicht dargestellt) zur Abgabe an eine Formateinrichtung 2. Der Faserstrang
wird hängend am Saugstrangförderer 1 im Tabakkanal 7 gefördert, wobei er mittels
eines durch den Saugstrangförderer 1 hindurchwirkenden Saugzugs aus einer den
Saugstrangförderer umschließenden Saugkammer 8 am Saugstrangförderer gehalten
wird. Das Formatbett 3 weist gemäß Figur 2 eine Strangführungsfläche 9 auf,
die einen im Querschnitt gewölbten Strangkanal bildet, dessen Wölbungsradius in
Laufrichtung des Strangs vom Einlaufkonus 11 zum Formatteil hin kontinuierlich
abnimmt und der in einen entsprechend der gewünschten Strangform ausgebildeten,
nicht weiter dargestellten Strangkanal der Formateinrichtung 2 mündet. Im
Einlaufkonus 11 entlang der Strangführungsfläche 9 und in dem nicht weiter dargestellten
Strangkanal der Formateinrichtung 2 ist ein in Pfeilrichtung 12 umlaufendes
Formatband 13 geführt, das einen Hüllmaterialstreifen 14 durch die Formateinrichtung
2 trägt. Diese Technik derartiger Maschinen ist hinlänglich bekannt, so daß
eine nähere Darstellung und Beschreibung hier nicht erforderlich ist. Im Bereich des
Einlaufkonus 11 konvergiert der Saugstrangförderer 1 zur Strangführungsfläche 9
des Formatbetts 3 und legt den in einer nicht dargestellten Strangaufbauzone aufgeschauerten
und in üblicher Weise egalisierten Tabakstrang auf den durch die
Formateinrichtung 2 bewegten Hüllmaterialstreifen 14 auf Dabei wird der Tabakstrang
bei seiner Passage durch den Einlaufkonus 11 unter der Wirkung des
Saugstrangförderers 1 stark komprimiert und entsprechend der Querschnittsveränderung
des Einlaufkonus in Förderrichtung 12 des Formatbandes 13 so verformt,
daß er in den teilweise von der Strangführungsfläche 9 des Formatbettes 3
umschlossenen Strangkanal einlaufen kann. Im Bereich der Strangführungsfläche 9
ist dem Formatbett 3 benachbart als weiteres Strangführungsmittel der Einlauffinger
4 mit einem Schaber 16 angeordnet, der zusammen mit der Strangführungsfläche 9
des Formatbettes 3 eine den Faserstrang weiter komprimierende und formende
Strangführung bildet.
Der Schaber 16 ist stirnseitig am Einlauffinger 4 der Formateinrichtung 2 befestigt.
Seine Unterseite ist als Strangführungsfläche 17 ausgebildet und liegt in der Einbauposition
des Schabers der Strangführungsfläche 9 des Formatbettes 3 gegenüber,
so daß beide Strangführungsflächen 9 und 17 einen Strangführungskanal
einschließen. Die Strangführungsfläche 17 ist dabei konkav gewölbt und fluchtet mit
einer anschließenden Strangführungsfläche 18, die an der Unterseite des Einlauffingers
4 ausgebildet ist. Diese Ausbildung der Strangführungsflächen bewirkt in
bekannter Weise das Verformen des ankommenden Tabakstrangs zu einem zylindrischen
Faserstrang bei gleichzeitiger Umhüllung dieses Faserstrangs mit dem
Hüllmaterialstreifen 14.
Im Bereich des Formateinlaufes ist der Saugstrangförderer 1 an seinem Abgabeende
um eine durch den Saugstrangförderer 1 in Umdrehung versetzte Preßscheibe
19 herumgeführt, wobei das gesamte Abgabeende und die Preßscheibe 19
durch als Messerleisten 21 ausgebildete Seitenwände abgedeckt ist, die sich unterseitig
bis entlang der Strangführungsfläche 9 im Formatbett 3 erstrecken. Zwischen
den beiden Messerleisten 21 ist zur Führung des Saugstrangförderers 1 ein sogenannter
Schubstreckenklotz 22 eingefügt, der mit einem schaberartigen Rückhaltekeil
23 mit einem Abstand im zehntel Millimeterbereich in dem zwischen der Preßscheibe
19 und dem Saugstrangförderer 1 gebildeten unteren Zwickel gegen die
Preßscheibe 19 angestellt ist. Oberseitig ist der Schubstreckenklotz 22 mit einem
gegen die Umfangsfläche der Preßscheibe 19 angestellten Schaber 24 ausgestattet.
Oberhalb des Rückhaltekeils 23 ist der Schubstreckenklotz 22 mit einer Ausnehmung
in Form eines Luftkanals 26 versehen, welcher in einem etwa
konzentrischen Verlauf zur Preßscheibe deren zwischen dem Ober- und Untertrum
des Saugstrangförderers 1 verlaufenden freien Umfangsabschnitt der Preßscheibe
19 zwischen dem Schaber 24 und dem Rückhaltekeil 23 begrenzt. Der Luftkanal 26
steht einerseits mit der Saugkammer 8 und andererseits mit dem inneren Lagerraum
27 der Preßscheibe 19 in Verbindung. Zu diesem Zweck ist die Preßscheibe
19 mit insgesamt acht beidseitig an ihrem Umfangsrand austretenden radialen Luftschlitzen
28 versehen, so daß beim Vorbeilauf der durch den Saugstrangförderer 1
freigegebenen Luftschlitze 28 im Bereich des Luftkanals 26 eine Strömungsverbindung
zwischen dem Lagerraum 27 der Preßscheibe 19 und der Saugkammer 8
hergestellt wird. Zur Effektivitätssteigerung der Saugströmung sind außerdem
Durchbrechungen 29 in der Stirnwand der Preßscheibe 19 sowie in den beiden
Messerleisten 21 jeweils im Bereich des unteren Endes des Luftkanals 26 Durchbrechungen
31 vorgesehen. Durch die auf diese Weise erzeugte permanente
Saugluftströmung von der Preßscheibe 19 zur Saugkammer 8 werden Staubpartikel,
die vom Schaber 24 nicht erfaßt und abgenommen werden konnten von der
Umfangsfläche der Preßscheibe 19 abgesaugt, so daß sich kein Tabakstaub zwischen
der Umfangsfläche der Preßscheibe 19 und dem Saugstrangförderer ansammeln
und zum Auftragen des Saugstrangförderers führen kann und somit eine
Beschädigung des Saugstrangförderers 1 durch den Schaber 17 verhindert wird.
Gleichzeitig werden durch die Passage des Luftkanals durch die Luftschlitze 28
Staubablagerungen im Lagerraum 27 der Preßscheibe 19 unterbunden, so daß
langfristig Lagerschäden verhindert werden.In Figure 1, the format inlet of a cigarette rod machine is shown. It shows the discharge end of a suction strand conveyor 1 designed as an air-permeable endless conveyor belt and part of a
