Description

Die Erfindung betrifft eine Fördereinrichtung zum Überführen von Filterstäben der Tabak verarbeitenden Industrie von einer Filterherstellmaschine zu Weiterverarbeitungseinrichtungen, mit einer einen mehrlagigen Filterstabmassenstrom bildenden, ein atmendes Speichervolumen umfassenden Transportstrecke.The invention relates to a conveyor for transferring filter rods Tobacco processing industry from a filter manufacturing machine to further processing facilities, with a multi-layer filter rod mass flow, a transport route comprising a storage volume that breathes.

Das Speichervolumen der eingangs bezeichneten Transportstrecke besteht bei herkömmlichen Einrichtungen aus einer Pufferstrecke, um zeitliche begrenzte betriebsbedingte Leistungsunterschiede zwischen der Filterherstellung und -verarbeitung oder Störungen der angeschlossenen Maschinen aufzufangen, sowie aus einer Filteraushärtestrecke, um den bei der Filterstabherstellung in Kleinsttröpfchen auf das Fasermaterial (Celluloseacetat) aufgesprühten Weichmacher (Triacetin) auszuhärten, wobei dieser zunächst die Filterfasern anlöst, miteinander verklebt und dann in das Celluloseacetat hinein diffundiert und dabei die Verklebungsstellen verfestigt.
Dieser üblicherweise bei Raumtemperatur stattfindende Vorgang bestimmt die Aufenthaltszeit der Filterstäbe in der Transportstrecke und damit auch deren Aufnahmekapazität, d. h. bei definierter mehrlagiger Höhe deren Länge.In conventional facilities, the storage volume of the transport line mentioned at the outset consists of a buffer line to compensate for time-limited operational differences in performance between filter production and processing or malfunctions of the connected machines, and a filter curing line in order to produce tiny droplets on the fiber material (cellulose acetate) during filter rod production. sprayed-on plasticizer (triacetin) to cure, this first dissolving the filter fibers, glued to one another and then diffusing into the cellulose acetate and thereby solidifying the bond points.
This process, which usually takes place at room temperature, determines the residence time of the filter rods in the transport path and thus also their absorption capacity, ie their length at a defined multilayer height.

Der Erfindung liegt die Aufgabe zugrunde, den baulichen Aufwand und Umfang für das genannte Speichervolumen zu reduzieren.The invention has for its object the structural complexity and scope for to reduce said storage volume.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass in die Transportstrecke eine den mehrlagigen Filterstabmassenstrom kontinuierlich durchschleusende Mikrowellenerwärmungsanlage integriert ist.
Die durch die Mikrowelleneinwirkung hervorgerufene Erwärmung der Filterstäbe kann am wirkungsvollsten zugunsten des Aushärtevorgangs gemäß einer Weiterbildung dadurch genutzt werden, dass die Mikrowellenerwärmungsanlage dem atmenden Speichervolumen - bezogen auf die Förderrichtung - stromauf vorgeordnet ist, so dass bei einer erzeugten Filterstabtemperatur von 50° C eine Aushärtungszeit von zwei Minuten in dem ausschließlich auf eine Pufferstrecke reduzierten Speichervolumen möglich ist.
Die Anordnung ist nach einem weiteren Vorschlag so getroffen, dass die Mikrowellenerwärmungsanlage zwischen dem mehrlagigen atmenden Speichervolumen und der die Filterstäbe einlagig queraxial abgebenden Filterherstellmaschine angeordnet ist, wodurch eine gute Zugänglichkeit der Mikrowellenerwärmungsanlage in Front der Produktionslinie für die Bedienungsperson erreicht ist.
Eine definierte Führung des mehrlagigen Filterstabmassenstroms und eine sichere Beherrschung und Einhaltung des Erwärmungsvorganges bzw. des Temperaturniveaus wird nach einer Weiterbildung dadurch erreicht, dass die Transportstrecke innerhalb der Mikrowellenerwärmungsanlage durch den Filterstabmassenstrom ober- und unterseitig führende Transportbänder gebildet wird.
Einer gleichmäßigen, durchdringenden Erwärmung des Filterstabmassenstromes dient eine Weiterbildung dadurch, dass die Mikrowellenerwärmungsanlage mit den Filterstabmassenstrom an durch die Umfangsflächen der Filterstäbe gebildeten entgegen gesetzten Längsseiten bestrahlenden Mikrowellenmodulen ausgestattet ist.This object is achieved according to the invention in that a microwave heating system which continuously flows through the multi-layer filter rod mass flow is integrated into the transport path.
The heating of the filter rods caused by the microwave action can be used most effectively in favor of the curing process according to a further development in that the microwave heating system is arranged upstream of the breathing storage volume - based on the conveying direction - so that a curing time of 50 ° C is generated at a generated filter rod temperature two minutes in which the storage volume is reduced to a buffer section only.
According to a further proposal, the arrangement is such that the microwave heating system is arranged between the multi-layer breathing storage volume and the filter production machine delivering the filter rods in one layer transversely axially, whereby the operator can easily access the microwave heating system in the front of the production line.
Defined guidance of the multi-layer filter rod mass flow and reliable control and compliance with the heating process or the temperature level is achieved according to a further development in that the transport path within the microwave heating system is formed by the filter rod mass flow on the top and bottom leading conveyor belts.
A further development serves for uniform, penetrating heating of the filter rod mass flow in that the microwave heating system is equipped with the filter rod mass flow on microwave modules irradiating opposite longitudinal sides formed by the peripheral surfaces of the filter rods.

Um die Intensität der Mikrowellenbestrahlung zwecks Einhaltung einer definierten Erwärmung des Filterstabmassenstromes jeweils den aktuellen Betriebsbedingungen anzupassen, wird weiterhin vorgeschlagen, dass die Mikrowellenmodule von einem auf die Maschinengeschwindigkeit der Filterherstellmaschine ansprechenden Pulsgenerator steuerbar sind.
Gemäß einer Variante wird vorgeschlagen, dass die Mikrowellenmodule mit einem in Abhängigkeit von der Maschinengeschwindigkeit der Filterherstellmaschine steuerbaren Selektionsgenerator in Wirkverbindung stehen, so dass beispielsweise bei einem verringerten Massenstromdurchsatz durch die Mikrowellenanlage ein oder mehrere Mikrowellenmodule abgeschaltet werden können, um eine gleichmäßige Temperatur des Filterstabmassentromes einzuhalten.
Alternativ können sowohl der Pulsgenerator als auch der Selektionsgenerator zwecks Steuerung der Wärmeeinwirkung und damit Einhaltung der Temperatur des Massenstromes nach einem weiteren Vorschlag der Pulsgenerator und/oder der Selektionsgenerator eine Signalverbindung mit einem auf den Filterstabmassenstrom ausgerichteten berührungslosen Temperatursensor aufweisen. Zweckmäßigerweise ist ein derartiger Temperatursensor auf eine durch die Stirnflächen der Filterstäbe gebildete Längsseite des Filterstabmassenstromes ausgerichtet.In order to adapt the intensity of the microwave radiation to the current operating conditions in order to maintain a defined heating of the filter rod mass flow, it is further proposed that the microwave modules can be controlled by a pulse generator that responds to the machine speed of the filter manufacturing machine.
According to a variant, it is proposed that the microwave modules are operatively connected to a selection generator that can be controlled as a function of the machine speed of the filter manufacturing machine, so that, for example, with a reduced mass flow throughput through the microwave system, one or more microwave modules can be switched off in order to maintain a uniform temperature of the filter rod mass flow.
Alternatively, both the pulse generator and the selection generator can have a signal connection with a contactless temperature sensor aligned with the filter rod mass flow for the purpose of controlling the effect of heat and thus maintaining the temperature of the mass flow, according to a further proposal of the pulse generator and / or the selection generator. Such a temperature sensor is expediently aligned with a long side of the filter rod mass flow formed by the end faces of the filter rods.

Der mit der Erfindung erzielte Vorteil besteht darin, dass die Aushärtung der mit Triacetin besprühten Celluloseacetat-Filterstäbe stark beschleunigt wird, so dass die für die Weiterverarbeitung der Filter benötigte Aushärtezeit auf ein Minimum verkürzt wird. Dies ermöglichst eine bedeutende Platzeinsparung, weil die Aushärtestrecke entfallen kann, so dass die Kapazität des Speichervolumens auf die Pufferstrecke reduziert wird. The advantage achieved by the invention is that the curing of the Triacetin sprayed cellulose acetate filter rods is greatly accelerated so that the curing time required for further processing of the filters to a minimum is shortened. This enables a significant saving of space because of the curing section can be omitted, so that the capacity of the storage volume on the Buffer section is reduced.

Darüber hinaus kann die Produktionsgeschwindigkeit der Filterstäbe trägheitslos dem Bedarf angepasst werden. Nach einer Betriebsunterbrechung der Filterherstellmaschine stehen sofort wieder verarbeitbare Filterstäbe zur Verfügung, was sich besonders bei einer weiteren Leistungssteigerung der Weiterverarbeitungseinrichtungen vorteilhaft auswirkt.In addition, the production speed of the filter rods can be inertia be adapted to the needs. After a break in operation of the filter manufacturing machine there are immediately reprocessable filter rods available, what particularly in the case of a further increase in the performance of the processing facilities has an advantageous effect.

Die Erfindung wird nachfolgend anhand eines in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert.
Die in der Zeichnung dargestellte Transportstrecke zum Überführen von Filterstäben 1 erstreckt sich von einer die Filterstäbe abgebenden Filterherstellmaschine 2 über eine Mikrowellenerwärmungsanlage 3 bis zu einem atmenden Speichervolumen 4.
Die auf bekannte, nicht dargestellte Weise auf der Filterherstellmaschine 2 erzeugten, Weichmacher (Triacetin) enthaltenden Filterstäbe 1 werden einzeln aufeinander folgend in queraxialer Ausrichtung aus Mulden 5 einer Abgabetrommel 10 in die unmittelbar angrenzende Mikrowellenerwärmungsanlage 3 überführt, wobei aus ihnen mittels eines sich trichterförmig erweiternden Einlaufs 6 ein mehrlagiger Filterstabmassenstrom 7 gebildet wird.
Der Filterstabmassenstrom 7 wird innerhalb der Mikrowellenerwärmungsanlage 3 zwischen oberen und unteren Transportbändern 8, 9 geführt.
Die Mikrowellenerwärmungsanlage 3 umfasst eine den Filterstabmassenstrom 7 umschließende Erwärmungskammer 11, die über Hohlleiter 12 mit Mikrowellenmodulen 13 in Wirkverbindung steht.
Die Energie erzeugenden Mikrowellenmodule 13 sind beidseitig bzw. ober- und unterseitig des Filterstabmassenstroms 7 bzw. der strahlungsdurchlässigen Transportbänder 8, 9 angeordnet. Den Mikrowellenmodulen 13 ist ein Pulsgenerator 14 zugeordnet, der eine eingangsseitige Signalverbindung 16 zu einem geschwindigkeitsabhängigen Drehzahlgeber 17 der Filterherstellmaschine 2 sowie auf alle The invention is explained in more detail below with reference to an embodiment shown in the drawing.
The transport path shown in the drawing for transferring filter rods 1 extends from a filter manufacturing machine 2 that emits the filter rods, via a microwave heating system 3, to a breathing storage volume 4.
The filter rods 1 which contain plasticizers (triacetin) and which are produced in a known manner (not shown) on the filter manufacturing machine 2 are successively transferred in transverse axial alignment from troughs 5 of a delivery drum 10 into the immediately adjacent microwave heating system 3, from them by means of a funnel-shaped inlet 6 a multi-layer filter rod mass flow 7 is formed.
The filter rod mass flow 7 is guided within the microwave heating system 3 between upper and lower conveyor belts 8, 9.
The microwave heating system 3 comprises a heating chamber 11 which surrounds the filter rod mass flow 7 and which is operatively connected to microwave modules 13 via waveguides 12.
The energy-generating microwave modules 13 are arranged on both sides or top and bottom of the filter rod mass flow 7 or the radiation-permeable conveyor belts 8, 9. A pulse generator 14 is assigned to the microwave modules 13, which has an input-side signal connection 16 to a speed-dependent speed sensor 17 of the filter manufacturing machine 2 and to all of them

Mikrowellenmodule 13 einwirkende, deren Aktivierungsphasen bestimmende Steuerpulsleitungen 18 aufweist.
Alternativ kann der Drehzahlgeber 17 über eine strichliert angedeutete Signalverbindung 19 mit einem Selektionsgenerator 21 verknüpft sein, der wahlweise bzw. geschwindigkeitsabhängig über Steuerleitungen 22 einzelne Mikrowellenmodule 13 zu- oder abschaltet.
Als weiteres alternatives oder zusätzliches Überwachungs- und Steuerorgan ist ein gegen die Filterstab-Stirnflächen des Filterstabmassenstromes 7 gerichteter Temperatursensor 23 vorgesehen, welcher zwecks Einhaltung der erzeugten Temperatur des Filterstabmassenstromes 7 über Steuerleitungen 24 bzw. 26 auf die zuvor beschriebenen Puls- bzw. Selektionsgeneratoren 14 bzw. 21 einwirkt oder auf nicht dargestellte Weise im Falle einer kritischen Temperaturerhöhung (Überhitzung, Brandgefahr) die Aggregate still setzt.
Der mit einer Höhe von ca. 80mm durch die Mikrowellenerwärmungsanlage 3 geschleuste und dabei auf ca. 50° C erwärmte Filterstabmassenstrom 7 benötigt nur ca. zwei Minuten zum Aushärten der mit Triacetin besprühten Filterstäbe 1, um weiter verarbeitet werden zu können. Für diese Zeitspanne reicht die Speicherkapazität des auf eine reine Pufferstrecke reduzierten atmenden Speichervolumens 4 aus, in das der Filterstabmassenstrom anschließend im Bereich einer Abzweigung 27 überführt wird.
Von der Abzweigung 27 gelangen die Filterstäbe 1 normalerweise nach unten in einen Durchlaufspeicher 28, der in Form einer Schleife von zwei übereinander angeordneten Förderbändern 29 und 31 gebildet wird. Ortsfeste Wände 32, 33, 34, 36 und 37 begrenzen das Speichervolumen. Ein Schacht 38 am Auslass 39 des Durchlaufspeichers 28 führt zu einer Weiterverarbeitungsmaschine 41. An der Abzweigung 27 überwacht ein Taster 42 den Filterstabstrom und steuert ein Bodenband 43 mit einer an ihm befestigten Endwand 44 eines Sackpuffers 46 derart, dass beim Anheben des Tasters 42 das Bodenband 43 von der Abzweigung 27 weg bewegt wird, wodurch der Sackpuffer 46 überschüssige Filterstäbe 1 aufnimmt, oder dass beim Absinken des Tasters 42 das Bodenband 43 auf die Abzweigung 27 zu bewegt wird, wodurch Filterstäbe 1 aus dem Sackpuffer 46 in den Durchlaufspeicher 28 abgegeben werden.
Der Durchlaufspeicher 28 kann zum Beispiel derart ausgelegt werden, dass bei einer Förderleistung von 6000 Filterstäben pro Minute die Verweilzeit der auf etwa 50° C erwärmten Filterstäbe im Speichervolumen immer wenigstens zwei Minuten beträgt, womit die erforderliche Aushärtezeit in jedem Fall eingehalten wird.Microwave modules 13 acting, whose activation phases have control pulse lines 18.
Alternatively, the speed sensor 17 can be linked via a signal connection 19 indicated by a broken line to a selection generator 21, which selectively switches on or off individual microwave modules 13 via control lines 22, depending on the speed.
As a further alternative or additional monitoring and control element, a temperature sensor 23 directed against the filter rod end faces of the filter rod mass flow 7 is provided, which in order to maintain the generated temperature of the filter rod mass flow 7 via control lines 24 and 26 to the pulse or selection generators 14 and / or 21 acts or, in a manner not shown, in the event of a critical increase in temperature (overheating, fire risk) stops the units.
The filter rod mass flow 7, which is passed through the microwave heating system 3 at a height of approximately 80 mm and heated to approximately 50 ° C., only requires approximately two minutes to harden the filter rods 1 sprayed with triacetin in order to be able to be further processed. For this period of time, the storage capacity of the breathing storage volume 4 reduced to a pure buffer section is sufficient, into which the filter rod mass flow is then transferred in the region of a branch 27.
From the branch 27, the filter rods 1 normally go down into a continuous storage 28 which is formed in the form of a loop by two conveyor belts 29 and 31 arranged one above the other. Fixed walls 32, 33, 34, 36 and 37 limit the storage volume. A shaft 38 at the outlet 39 of the continuous storage 28 leads to a further processing machine 41. At the branch 27, a button 42 monitors the filter rod flow and controls a bottom belt 43 with an end wall 44 of a bag buffer 46 fastened to it in such a way that when the button 42 is raised, the bottom belt 43 is moved away from the branch 27, as a result of which the bag buffer 46 receives excess filter rods 1, or that when the button 42 sinks, the base band 43 is moved towards the branch 27, as a result of which filter rods 1 are discharged from the bag buffer 46 into the passage memory 28.
The continuous storage 28 can, for example, be designed in such a way that with a delivery rate of 6000 filter rods per minute, the dwell time of the filter rods heated to approximately 50 ° C. in the storage volume is always at least two minutes, which means that the required curing time is maintained in any case.
