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
The filter rods 1 which contain plasticizers (triacetin) and which are produced in a known manner (not shown) on the
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
The energy-generating
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.
Alternatively, the
As a further alternative or additional monitoring and control element, a
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
From the
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.
