Description

Die Erfindung betrifft Partikel absonderndes Umhüllungsmaterial für Gegenstände der tabakverarbeitenden Industrie kontaktierende Transportmittel.The invention relates to particle-separating wrapping material for objects means of transport contacting the tobacco processing industry.

Zum Transport, beispielsweise zum Abzug von einer Weiterverarbeitung zugeführtem Umhüllungspapier für Zigaretten, Filter oder einer Kombination aus beiden Komponenten über Abzugswalzen oder zum Transport bzw. zur Handhabung der genannten, einem Wickelvorgang unterzogenen oder bereits umhüllten Gegenstände mit Hilfe von sogenannten Funktionsbändern ist eine bestimmte Oberflächenrauhigkeit der genannten Fördermittel erforderlich. Zu diesem Zweck werden die Abzugswalzen zur Erzielung einer entsprechenden Zugkraft sowie die Funktionsbänder zur Erzielung einer definierten Haltekraft oder einen Rollvorgang unterstützenden Mitnehmerwirkung an ihrer Oberfläche mit einer griffigen Beschichtung, zum Beispiel Kautschuk, versehen. Eine derartige elastische Kautschukoberfläche besitzt nach dem erforderlichen Schleifvorgang eine zerklüftete, im wesentlichen schuppenförmige Struktur, die den Reibwert erhöht. Im Kontakt mit Papier bzw. durch Reibung der Zigaretten während eines Rollvorgangs wird die Oberflächenstruktur unter Verlust der anfänglichen Griffigkeit geglättet. Hinzu kommen Papierablagerungen in Form von Papierstaub, Kreide und sonstigen Füllstoffen, die in den Poren bzw. Vertiefungen der Schuppenstruktur der Kautschukoberfläche haften bleiben. Durch die mechanische Glättung und die Ablagerungen wird der Reibwert der Förderorgane erheblich vermindert und damit deren Funktion gestört.
Der Versuch, diese Ablagerungen herauszuwaschen, hat sich als erfolglos erwiesen, so dass die betreffenden Förderorgane vorzeitig ausgetauscht werden müssen, ohne dass sie verschlissen sind.A certain surface roughness is required for transport, for example for the removal of wrapping paper for cigarettes, filters or a combination of both components via removal rollers, or for the transport or handling of the objects mentioned, which have been subjected to a winding process or have already been wrapped, with the aid of so-called functional bands mentioned funding required. For this purpose, the take-off rollers are provided with a non-slip coating, for example rubber, on their surface in order to achieve a corresponding tensile force and the functional belts to achieve a defined holding force or a driving action that supports a rolling process. After the required grinding process, such an elastic rubber surface has a fissured, essentially scale-like structure which increases the coefficient of friction. In contact with paper or due to friction of the cigarettes during a rolling process, the surface structure is smoothed out, losing the initial grip. In addition, there are paper deposits in the form of paper dust, chalk and other fillers that stick to the pores or depressions in the scale structure of the rubber surface. Due to the mechanical smoothing and the deposits, the coefficient of friction of the conveying elements is considerably reduced and their function is thus disturbed.
The attempt to wash out these deposits has proven unsuccessful, so that the relevant funding bodies have to be replaced prematurely without being worn out.

Der Erfindung liegt die Aufgabe zugrunde, Maßnahmen zu treffen, welche die Standzeit der eingangs genannten Fördermittel wesentlich verlängern.The invention has for its object to take measures that the Significantly extend the service life of the funds mentioned at the beginning.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass die mit einer reibschlüssigen Transportoberfläche ausgestatteten Transportmittel mit einer den Reibwert der Transportoberfläche langfristig aufrechterhaltenden Beschichtung versehen sind.
Eine bevorzugte wirksame Maßnahme zur langfristigen Aufrechterhaltung des Reibwertes wird nach einem weiteren Vorschlag dadurch erreicht, dass die Oberfläche der Transportmittel mit einer Papierbestandteile (Papierstaub, Kreide und andere Füllstoffe) abweisenden Schutzschichtversiegelung versehen ist.
Um durch eine extrem dünne Beschichtung einerseits die grobe Oberflächenstruktur der Fördermittel beizubehalten und andererseits eine Ablagerungen verhindernde und abweisende Beschaffenheit der Oberfläche zu erreichen, wird nach einem weiteren Vorschlag eine die Vertiefungen (Poren) in der Oberflächenstruktur der Transportmittel verschließende, elastische und eine gute Haftung auf dem Untergrund aufweisende Schutzschichtversiegelung bevorzugt. Auf diese Weise wird mit Hilfe einer extrem dünnen Beschichtung eine optimale Wirkung erzielt.
Es ist weiterhin vorgesehen, dass die Schutzschichtversiegelung eine für die deutsche Tabakverordnung verbindliche Norm erfüllt.
Eine die genannten Forderungen erfüllende Beschichtung besteht nach einem weiteren Vorschlag darin, dass die Schutzschichtversiegelung aus Polyvinylacetat (PVAC) besteht. Eine alternative bevorzugte Beschichtung besteht nach einem weiteren Vorschlag darin, dass die Schutzschichtversiegelung aus einer Acrylatdispersion besteht, mit den zusätzlichen Vorteilen, dass sie eine bessere Haftung auf dem Trägermaterial aufweist, wasserunlöslich ist und einen einstellbaren Reibwert möglich macht.
Die Erfindung ist anwendbar zum Beispiel auf Transportwalzen in Form von Abzugswalzen, die mit einer Kautschukbeschichtung versehen sind und Streifen aus Umhüllungspapier für die nachträgliche Konfektionierung von Zigaretten oder Filtern transportieren bzw. aus einem Vorrat abziehen. Die erfindungsgemäßen Maßnahmen verhindern eine Glättung bzw. Reibwertverminderung der Walzenoberfläche und dadurch bedingten Schlupf zwischen Papierstreifen und Transportwalze. Ein weiteres denkbares Anwendungsbeispiel besteht vorschlagsgemäß darin, dass die Transportmittel aus eine Kautschukoberfläche aufweisenden, insbesondere aus paarweise gegenüberliegenden, stabförmige Gegenstände durch kraftschlüssiges Erfassen handhabenden Funktionsbändern bestehen. In diesem Umfang sind die vorgeschlagenen Maßnahmen gemäß einer Weiterbildung besonders wirksam, wenn die mit unterschiedlichen Geschwindigkeiten ihrer benachbarten Trume vorbewegten Funktionsbänder einen Rollkanal zum Umhüllen und Verbinden von stirnseitig aneinandergefügten stabförmigen Gegenständen begrenzen.
Eine in Verbindung mit einem derartigen Rollkanal bevorzugte Ausgestaltung besteht darin, dass das mit einer geringeren Geschwindigkeit umlaufende, mit einem höheren Reibwert ausgestattete Funktionsband mit der Beschichtung versehen ist, so dass über eine definierte Förderstrecke eine schlupffreie einfache oder mehrfache Überrollung der Artikel möglich ist. This object is achieved according to the invention in that the transport means equipped with a frictional transport surface are provided with a coating which maintains the coefficient of friction of the transport surface over the long term.
According to a further proposal, a preferred effective measure for long-term maintenance of the coefficient of friction is achieved in that the surface of the means of transport is provided with a protective layer seal that repels paper components (paper dust, chalk and other fillers).
In order to maintain the coarse surface structure of the conveying means by means of an extremely thin coating on the one hand, and on the other hand to achieve a deposit-preventing and repellent nature of the surface, according to a further proposal, the recesses (pores) in the surface structure of the means of transport are closed and elastic and good adhesion the protective layer sealing provided on the substrate is preferred. In this way, an extremely thin coating achieves an optimal effect.
It is also envisaged that the protective layer sealing will meet a standard that is binding for the German tobacco regulation.
According to a further proposal, a coating that fulfills the requirements mentioned is that the protective layer seal consists of polyvinyl acetate (PVAC). According to a further proposal, an alternative preferred coating consists in that the protective layer seal consists of an acrylate dispersion, with the additional advantages that it has better adhesion to the carrier material, is water-insoluble and makes an adjustable coefficient of friction possible.
The invention is applicable, for example, to transport rollers in the form of take-off rollers which are provided with a rubber coating and which transport strips of wrapping paper for the subsequent assembly of cigarettes or filters or take them off from a supply. The measures according to the invention prevent smoothing or a reduction in the coefficient of friction of the roller surface and consequent slippage between the paper strip and the transport roller. According to the proposal, another conceivable example of use consists in the fact that the transport means consist of functional bands that have a rubber surface, in particular of rod-shaped objects that are opposite one another in pairs, by means of force-locking gripping. To this extent, the proposed measures are particularly effective according to a further development if the functional belts moved forward at different speeds of their neighboring strands delimit a rolling channel for enveloping and connecting rod-shaped objects joined together on the end face.
A preferred embodiment in connection with such a rolling channel is that the functional belt rotating at a lower speed and equipped with a higher coefficient of friction is provided with the coating, so that slip-free, single or multiple rolling over of the articles is possible over a defined conveying path.

Der mit der Erfindung erzielte Vorteil besteht darin, dass mit der Schutzschichtversiegelung ein Verschluss der Vertiefungen in der Oberflächenstruktur erzielt wird, wodurch Ablagerungen von glatten Papierbestandteilen unterbunden werden. Es hat sich gezeigt, dass zwar der Anfangsreibwert bzw. die Anfangsrauhigkeit durch die Beschichtung geringfügig abnimmt, dass sich jedoch die betriebsbedingte Abnahme des Reibwertes deutlich verlangsamt und sich somit die Standzeit der Fördermittel erhöht.
Darüber hinaus konnten Funktionsbänder, die aufgrund von Papierablagerungen nicht mehr funktionsfähig waren, nach dem Beschichten wieder eingesetzt werden.The advantage achieved by the invention is that the protective layer sealing closes the depressions in the surface structure, as a result of which deposits of smooth paper components are prevented. It has been shown that the initial coefficient of friction or the initial roughness decreases slightly as a result of the coating, but that the decrease in the coefficient of friction due to operation slows down significantly and thus increases the service life of the funding.
In addition, functional tapes that were no longer functional due to paper deposits could be used again after coating.

Die Erfindung wird anhand eines in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert.The invention is based on an embodiment shown in the drawing explained in more detail.

Die Zeichnung zeigt eine bevorzugte Ausführungsform der erfindungsgemäßen Vorrichtung in einer Seitenansicht. Die Vorrichtung weist eine Versorgungstrommel 1 auf, welche mit Hilfe von nicht dargestellten Unterdruckkanälen die zu umwickelnden Gegenstände 2 mit bereits - von der Versorgungstrommel 1 aus gesehen- außen an den zu umwickelnden Gegenständen 2 angehefteten Blättchen 3 zuführt. Bei den Gegenständen 2 handelt es sich um Zigarette-Filter-Zigarette-Gruppen. Die Zigarette-Filter-Zigarette-Gruppen 2 werden von der Versorgungstrommel 1 in umfangsseitig ausgebildeten, achsparallelen Mulden 4 geführt und durch nicht dargestellte Unterdruckkanäle gehalten.
Im Bereich der Position 6 werden die Zigarette-Filter-Zigarette-Gruppen 2 an eine Zufördertrommel 7 übergeben. Die Zufördertrommel 7 läuft mit gegenüber der Drehrichtung 8 der Versorgungstrommel 1 entgegengesetzter Drehrichtung 9 um. Die beiden Trommeln 1 und 7 laufen um parallel angeordnete Drehachsen.
Die Zufördertrommel 7 weist an ihrem Umfang 11 zueinander beabstandete Stege 12 auf. Die Stege 12 sind in regelmäßigen Abständen angeordnet und verlaufen parallel zur Drehachse der Zufördertrommel 7. Im Bereich der Stege 12 münden nicht dargestellte Unterdruckkanäle, mit deren Hilfe die Zigarette-Filter-Zigarette-Gruppen 2 an den Stegen 12 gehalten werden.
Im Bereich der Position 6 ist der radiale Abstand der Versorgungstrommel 1 und der Zufördertrommel 7 derart eingestellt, dass die Zigarette-Filter-Zigarette-Gruppe 2, die sich an dieser Position 6 befindet, von einem Steg 12, der sich an dieser Stelle gerade befindet, aus der Mulde 4 übernommen werden kann. Auf diese Weise werden die übernommenen Zigarette-Filter-Zigarette-Gruppen 4 durch den anliegenden Unterdruck an den Stegen 12 der Zufördertrommel 7 gehalten. Weitere, nicht dargestellte Unterdruckkanäle in der Zufördertrommel 7 halten die an den Zigarette-Filter-Zigarette-Gruppen 2 angehefteten Blättchen 3 am Umfang der Zufördertrommel 7.
Die zu umwickelnden Zigarette-Filter-Zigarette-Gruppen 2 werden dann zu einer Position A überführt, an der sie mit einem ebenfalls auf der Zufördertrommel 7 umlaufenden ersten Rollband 13 in Kontakt gebracht werden. Ebenfalls an der genannten Position A tritt die Zigarette-Filter-Zigarette-Gruppe 2 gleichzeitig in Kontakt mit einem zweiten Rollband 14, das an seiner unregelmäßig strukturierten Oberfläche auf nicht erkennbare Weise mit einer relativ dünnen, lediglich die Poren der Kautschukoberfläche des Rollbandes 14 verschließenden Schutzschichtversiegelung versehen ist, wodurch einerseits die einen definierten Reibwert gewährleistende Rauhigkeit und andererseits eine Staubablagerungen abweisende Eigenschaft der Kautschukoberfläche erhalten werden. Das erste Rollband 13 läuft mit der Umfangsgeschwindigkeit 9 der Zufördertrommel 7 um. Das zweite Rollband 14 läuft mit gegenüber der Geschwindigkeit 16 des ersten Rollbandes 13 verminderter Geschwindigkeit 17 um. Im Bereich der Position A beginnt somit ein Rollkanal 18. Durch die höhere Geschwindigkeit 16 des ersten Rollbandes 13 gegenüber der Geschwindigkeit 17 des zweiten Rollbandes 14 werden die Zigarette-Filter-Zigarette-Gruppen 2 in dem Rollkanal 18 mit dem Blättchen 3 umrollt. Die Anzahl der Umrollungen der Zigarette-Filter-Zigarette-Gruppen 2 in den Rollkanal 18 hängt von der Differenz der Geschwindigkeiten 16 bzw. 17 der Rollbänder 13 bzw. 14 ab. Durch Verändern der Geschwindigkeit 16 des Rollbandes 13 kann die Anzahl der Umrollungen der Zigarette-Filter-Zigarette-Gruppen 2 in dem Rollkanal 18 verändert werden. Das erste Rollband 13 und das zweite Rollband 14 haben im Bereich des Rollkanals 18 gleichgerichtete Förderrichtungen.
Am Ende des Rollkanals 18, an der in der Zeichnung mit B gekennzeichneten Position, verlassen die Zigarette-Filter-Zigarette-Gruppen 2 den Rollkanal 18. An dieser Stelle werden die Zigarette-Filter-Zigarette-Gruppen 2 von einer Abfördertrommel 19 übernommen. Die Abfördertrommel 19 weist ebenfalls umfangsseitig angeordnete Stege 21 auf. Die Abfördertrommel 19 läuft mit einer Umfangsgeschwindigkeit 22 im Uhrzeigersinn, gleichgerichtet mit der Zufördertrommel 7 um. Die Geschwindigkeit 22 der Abfördertrommel 19 ist geringer als die Fördergeschwindigkeit 16 des ersten Rollbandes 13. Somit werden die den Rollkanal 18 an der Position B verlassenden Zigarette-Filter-Zigarette-Gruppen 2 von dem ersten Rollband 13 gegen die als Aufnahmen an der Abfördertrommel 19 dienenden Stege 23 gedrückt. An den Stegen 23 sind ebenfalls nicht dargestellte Unterdruckkanäle zum Halten der Zigarette-Filter-Zigarette-Gruppen 2 vorgesehen. Anschließend werden die umwickelten Zlgarette-Filter-Zigarette-Gruppen 2 von der Abfördertrommel 19 an eine vierte Trommel 24 zur Weiterverarbeitung übergeben.The drawing shows a preferred embodiment of the device according to the invention in a side view. The device has a supply drum 1 which, with the aid of vacuum channels (not shown), supplies the objects 2 to be wrapped with leaves 3 already attached to the objects 2 to be wrapped, as seen from the supply drum 1. The objects 2 are cigarette-filter-cigarette groups. The cigarette-filter-cigarette groups 2 are guided by the supply drum 1 in circumferentially formed, axially parallel troughs 4 and held by vacuum channels, not shown.
In the area of position 6, the cigarette-filter-cigarette groups 2 are transferred to a feed drum 7. The feed drum 7 rotates with the direction of rotation 9 opposite to the direction of rotation 8 of the supply drum 1. The two drums 1 and 7 run around axes of rotation arranged in parallel.
The feed drum 7 has webs 12 spaced apart from one another on its circumference 11. The webs 12 are arranged at regular intervals and run parallel to the axis of rotation of the feed drum 7. In the area of the webs 12, vacuum channels (not shown) open, with the aid of which the cigarette-filter-cigarette groups 2 are held on the webs 12.
In the area of the position 6, the radial distance between the supply drum 1 and the feed drum 7 is set such that the cigarette-filter-cigarette group 2, which is located at this position 6, from a web 12, which is located at this point , can be taken from the trough 4. In this way, the cigarette-filter-cigarette groups 4 which have been taken over are held by the negative pressure present on the webs 12 of the feed drum 7. Further vacuum channels (not shown) in the feed drum 7 hold the leaflets 3 attached to the cigarette-filter-cigarette groups 2 on the circumference of the feed drum 7.
The cigarette-filter-cigarette groups 2 to be wrapped are then transferred to a position A, at which they are brought into contact with a first roller belt 13, which also rotates on the feed drum 7. Also at said position A, the cigarette-filter-cigarette group 2 simultaneously comes into contact with a second roller belt 14, which has an irregularly structured surface in a non-recognizable manner with a relatively thin protective layer seal that only seals the pores of the rubber surface of the roller belt 14 is provided, whereby on the one hand the roughness which ensures a defined coefficient of friction and on the other hand a property which repels dust deposits are obtained from the rubber surface. The first roller belt 13 rotates at the peripheral speed 9 of the feed drum 7. The second roller belt 14 rotates at a speed 17 which is lower than the speed 16 of the first roller belt 13. A rolling channel 18 thus begins in the area of position A. Due to the higher speed 16 of the first rolling belt 13 compared to the speed 17 of the second rolling belt 14, the cigarette-filter-cigarette groups 2 are rolled over with the leaflet 3 in the rolling channel 18. The number of rewindings of the cigarette-filter-cigarette groups 2 in the roller channel 18 depends on the difference in the speeds 16 and 17 of the roller belts 13 and 14, respectively. By changing the speed 16 of the roller conveyor 13, the number of rewindings of the cigarette-filter-cigarette groups 2 in the roller channel 18 can be changed. The first roller belt 13 and the second roller belt 14 have conveying directions in the same direction in the region of the roller channel 18.
At the end of the rolling channel 18, at the position marked B in the drawing, the cigarette-filter-cigarette groups 2 leave the rolling channel 18. At this point, the cigarette-filter-cigarette groups 2 are taken over by a removal drum 19. The discharge drum 19 also has webs 21 arranged on the circumference. The discharge drum 19 rotates clockwise at a peripheral speed 22, in the same direction as the feed drum 7. The speed 22 of the conveying drum 19 is lower than the conveying speed 16 of the first roller belt 13. Thus, the cigarette-filter-cigarette groups 2 leaving the rolling channel 18 at position B are separated from the first roller belt 13 by those serving as receptacles on the conveying drum 19 Bars 23 pressed. Vacuum channels (not shown) for holding the cigarette-filter-cigarette groups 2 are also provided on the webs 23. Subsequently, the wrapped Zlgarette-Filter-cigarette groups 2 are transferred from the discharge drum 19 to a fourth drum 24 for further processing.
