Description

Die Erfindung betrifft eine Regelungsanordnung für einen Filteransetzer sowie ein Verfahren zur Regelung der Abgabe der Prozessluft eines Filteransetzers an ein Abluftzentralsystem. Eine derartige Anordnung und Verfahren sind aus EP-A-2 238 844 bekannt.The invention relates to a control arrangement for a filter piecing and a method for controlling the delivery of the process air of a filter tappet to an exhaust air central system. Such an arrangement and method are out EP-A-2 238 844 known.

Derartige Filteransetzer finden bei der Zigarettenherstellung Verwendung. Es handelt sich dabei um Maschinen, in denen strangartige Zwischenprodukte bei der Zigarettenherstellung auf Qualität geprüft und bei Bedarf mit einem Filter versehen werden. Um die Zwischenprodukte sowie die Filter und die Produkte innerhalb der Maschine zu handhaben, werden dabei in der Regel Fördersysteme eingesetzt, die darauf beruhen, dass die zu fördernden Gegenstände durch einen Unterdruck an bewegliche Teile der Fördereinrichtung angesaugt werden. Der notwendige Unterdruck wird dabei abhängig von der jeweiligen Ausgestaltung und Einbindung der Maschine in den Gesamtprozess zum Einen von einem Abluftzentralsystem zur Verfügung gestellt und zum Anderen durch eine oder mehrere in die Maschine integrierte oder eine oder mehrere der Maschine zugeordnete Luftfördereinrichtungen erzeugt.Such filter tappets are used in cigarette production. These are machines in which strand-like intermediates are tested for quality in the production of cigarettes and, if necessary, provided with a filter. In order to handle the intermediates as well as the filters and the products within the machine, usually conveyor systems are used, which are based on the fact that the objects to be conveyed are sucked by a negative pressure to moving parts of the conveyor. The necessary negative pressure is provided depending on the particular design and integration of the machine in the overall process on the one hand by an exhaust air central system and on the other hand by one or more integrated into the machine or one or more of the machine associated air conveyors generated.

Zur Erzeugung des Unterdrucks ist es notwendig, eine gewisse Luftmenge an das Abluftzentralsystem abzugeben. Abhängig von den verschiedenen Betriebszuständen der Maschine variiert diese Luftmenge. Wird eine Maschine beispielsweise ohne Zufuhr der für die Herstellung benötigten Halbzeuge betrieben und demzufolge keine zu fördernden Gegenstände an die Fördereinrichtungen angesaugt, so ergibt sich eine deutlich größere Abluftmenge als beim regulären Betrieb der Maschine. Problematisch daran ist, dass beim Auftreten dieser Betriebszustände durch Schwankungen der von der Maschine an das Abluft-zentralsystem abgegebenen Luftmenge auch andere an das Abluftzentralsystem angeschlossene Maschinen beeinflusst werden können.To generate the negative pressure, it is necessary to deliver a certain amount of air to the exhaust air central system. Depending on the different operating conditions of the machine, this air quantity varies. If a machine is operated, for example, without supply of the semifinished products required for the production and therefore no sucking promotional objects to the conveyors, so there is a much larger amount of exhaust air than the regular operation of the machine. The problem with this is that when these operating conditions occur, fluctuations in the amount of air discharged from the machine to the exhaust air central system can affect other machines connected to the exhaust air central system.

Um die Luftmenge auf einem möglichst konstanten Niveau zu halten, werden daher nach dem Stand der Technik Drosselklappen zwischen dem Abluftausgang des Filteransetzers und dem Abluftzentralsystem vorgesehen, die zwischen verschiedenen, in der Regel aus Erfahrungswerten ermittelten Stellpositionen umgeschaltet werden können. So können beispielsweise Stellpositionen für Betriebszustände wie Stand-by-Betrieb, Standardbetrieb oder Betrieb im Leerlauf, d.h. ohne Zufuhr der zu verarbeitenden Zwischenprodukte, vorgesehen sein.In order to keep the amount of air at a constant level as possible, therefore, according to the prior art, throttle valves are provided between the exhaust air outlet of the filter tappet and the exhaust air central system, which can be switched between different, usually from empirical values determined parking positions. For example, adjustment positions for operating conditions such as stand-by, standard or idle, i.e., idle, can be used. without supply of the intermediates to be processed, be provided.

Nachteil ist jedoch, dass selbst wenn durch Umschalten der Drosselklappe die Beeinflussung anderer an das Abluftzentralsystem angeschlossener Maschinen im regulären Betrieb weitgehend unterbunden werden kann, beim Auftreten von Schwankungen von Prozessparametern an einem Filterdurchsetzer es zu Schwankungen der Betriebsparameter des Abluftzentralsystems kommen kann. Diese Schwankungen können Störungen weiterer angeschlossener Maschinen verursachen und im schlimmsten Fall zur Unterbrechung der gesamten Zigarettenproduktion, die an das Abluftzentralsystem angeschlossen ist, führen.Disadvantage, however, that even if by switching the throttle influencing other connected to the exhaust system centralized machines can be largely prevented in normal operation, when fluctuations of process parameters on a filter interrupter fluctuations in the operating parameters of the exhaust system can occur. These variations may cause malfunction of other connected machines and, in the worst case, may interrupt the entire cigarette production connected to the exhaust air system.

Die DE 10 2008 020 631 B3 offenbart ein Verfahren zum Betrieb einer Maschine der in Rede stehenden Art, bei dem in Betriebsphasen wie dem Start- oder dem Stoppvorgang, bei dem ein erhöhter Luftvolumenstrom an das Abluftzentralsystem abgegeben wird, ein Teilstrom des Abluftstromes in die Maschine zurückgeführt wird, um das Abluftzentralsystem zu entlasten. Die Steuerung des zurückgeführten Luftvolumenstroms beruht dabei auf einer Druckregelung, bei der über den zurückgeführten Luftvolumenstrom der Druck in dem zum Abluftzentralsystem führenden Rohr geregelt wird. Die Verwendung einer derartigen Druckregelung bringt jedoch den Nachteil mit sich, dass die gegenseitige Beeinflussung einer Mehrzahl an das Abluftzentralsystem angeschlossener Maschinen weiterhin nicht wirksam vermieden wird. Ändern sich Betriebszustände einzelner an das Abluftzentralsystem angeschlossener Maschinen und damit deren an das Abluftzentralsystem abgegebene Luftvolumenströme, so beeinflussen die hierdurch verursachten Druckschwankungen, die sich durch Rückstaueffekte in allen zum Abluftzentralsystem führenden Rohren ergeben, auch die Druckregelungen der anderen Maschinen. Die gegenseitige Beein-flussung der einzelnen Maschinen kann durch eine derartige Druckregelung im ungünstigsten Fall sogar verstärkt werden, wenn ein Druckanstieg im Rohrsystem, der durch eine erhöhte Abluftabgabe einer Maschine an das Abluftzentralsystem verursacht wurde, dazu führt, dass die Druckregelung einer anderen Maschine den in der anderen Maschine zurückgeführten Volumenstrom erhöht, wodurch sich die Prozessparameter der betroffenen Maschine ändern, was zu Betriebsstörungen führen kann.The DE 10 2008 020 631 B3 discloses a method of operating a machine of the type in question, wherein in operating phases such as the start or stop, in which an increased volume of air flow is delivered to the exhaust air central system, a partial flow of the exhaust air flow is fed back into the machine to the exhaust air central system relieve. The control of the recirculated air volume flow is based on a pressure control, in which the pressure in the pipe leading to the exhaust-air central system is regulated via the recirculated air volume flow. However, the use of such a pressure control has the disadvantage that the mutual influence of a plurality of machines connected to the exhaust air central system is still not effectively avoided. If operating conditions of individual machines connected to the exhaust-air central system change, and thus their air volume flows emitted to the exhaust-air central system, the pressure fluctuations caused thereby, which result from backflow effects in all pipes leading to the exhaust-air central system, also influence the pressure controls of the other engines. The mutual influence of the individual machines can be exacerbated by such a pressure control in the worst case, even if a pressure increase in the pipe system, which was caused by an increased exhaust air discharge of a machine to the exhaust system, causes the pressure control of another machine in the increases the flow rate returned to the other machine, which changes the process parameters of the affected machine, which can lead to malfunction.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Regelungsanordnung und ein Regelungsverfahren aufzuzeigen, die es ermöglichen, einen störungsfreien Weiterbetrieb anderer an ein Abluftzentralsystem angeschlossener Maschinen unabhängig von den Betriebszuständen des Zigarettenansetzers zu ermöglichen.The invention is therefore based on the object to show a control arrangement and a control method, which make it possible to enable a trouble-free continued operation of other connected to an exhaust air system machines regardless of the operating conditions of the cigarette holder.

Erfindungsgemäß wird die Aufgabe gelöst durch eine Regelungsanordnung mit den Merkmalen des Anspruchs 1 sowie ein Verfahren zur Regelung der Abgabe der Prozessluft eines Filteransetzers an ein Abluftzentralsystem mit den Merkmalen des Anspruchs 10. Die Merkmale der Unteransprüche betreffen vorteilhafte Ausführungsformen.According to the invention the object is achieved by a control arrangement with the features of claim 1 and a method for controlling the delivery of the process air of a Filteransetzers to an exhaust air system with the features of claim 10. The features of the dependent claims relate to advantageous embodiments.

Erfindungsgemäß ist vorgesehen, den Mengenstrom der Prozessluft, der von dem Filteransetzer an das Abluftzentralsystem abgegeben wird, zu regeln. Die Prozessluft, die bei der Unterdruckerzeugung in dem Fördersystem, welches dem Transport der Tabakprodukte bzw. der Tabakzwischenprodukte im Filteransetzer dient, wird - wie bei konventionellen Zigarettenherstellungsprozessen auch - aus dem Filteransetzer geleitet und in ein Abluftzentralsystem eingespeist. Dabei wird jedoch zwischen dem Prozessluftausgang des Filteransetzers und dem Eingang des Abluftzentralsystems anstelle einer einfachen Drosselklappe eine Mengenstromregelung eingebaut, die in der Lage ist, den Mengenstrom der vom Filter-ansetzer abgegebenen Abluft zu erfassen und aufgrund vorgegebener oder vorgebbarer Parameter auf Sollwerte bzw. Sollwertbereiche zu regeln. Eine derartige Regelung reagiert im Gegensatz zu konventionellen Lösungen selbsttätig auf sich durch Betriebsstörungen in einem Zigarettenfilteransetzer ergebende Schwankungen des von diesem abgegebenen Abluftstroms, so dass die unerwünschten Schwankungen im Abluftzentralsystem ohne manuelle Eingriffe wirksam verhindert oder zumindest gemildert werden können.According to the invention, it is provided to regulate the mass flow of the process air which is discharged from the filter tappet to the exhaust air central system. The process air, which is used in the production of negative pressure in the conveyor system, which is used to transport the tobacco products or the tobacco intermediates in the filter applicator, is - as in conventional cigarette manufacturing processes - conducted out of the filter piecing and fed into an exhaust air central system. In this case, however, instead of a simple throttle valve, mass flow control is installed between the process air outlet of the filter tappet and the inlet of the exhaust air central system, which is able to detect the mass flow of the exhaust air discharged from the filter tappet and to set values or setpoint ranges on the basis of predefined or specifiable parameters regulate. Such a scheme reacts in contrast to conventional solutions automatically due to malfunction in Variations in the exhaust air flow emitted by the cigarette filter follower are such that the unwanted fluctuations in the exhaust air central system can be effectively prevented or at least mitigated without manual intervention.

Vorzugsweise weist die Regelungsanordnung dabei eine Steuerung auf, die geeignet ist, einen Druck unterhalb eines vorgegebenen oder vorgebbaren Höchstwerts zu halten, indem die Regelungscharakteristik der Mengenstromregelung sowie deren Sollwerte durch die Steuerung selbsttätig entsprechend der Anforderungen an den Höchstwert des Drucks angepasst werden. Dies ermöglicht es, sicherzustellen, dass im Fall einer Betriebszustandsänderung in einem Filteransetzer und einer erhöhten Abluftabgabe desselben infolge der Betriebszustandsänderung ein Höchstdruck im Abluft-zentralsystem nicht überschritten wird. Insbesondere die Verhinderung des Überschreitens eines Höchstdrucks im Abluftzentralsystem ist relevant, wenn weitere Maschinen an das Abluftzen-tralsystem angeschlossen werden und Abluft in das Abluftzentralsystem abgeben sollen.In this case, the control arrangement preferably has a control which is suitable for keeping a pressure below a predefined or predefinable maximum value, in that the control characteristic of the mass flow control and its setpoint values are automatically adjusted by the control according to the requirements for the maximum value of the pressure. This makes it possible to ensure that in the event of a change in operating state in a filter piecing and an increased exhaust air discharge thereof as a result of the operating state change, a maximum pressure in the exhaust air central system is not exceeded. In particular, the prevention of exceeding a maximum pressure in the exhaust air central system is relevant if additional machines are to be connected to the Abluftzen- tralsystem and should deliver exhaust air in the exhaust air system.

Dabei wird der unter einem Höchstwert zu erzeugende Druck vorzugsweise mit einer Druckmesseinrichtung gemessen, die im Bereich der Verzweigungen der Eingänge des Abluftzentralsystems vorgesehen ist, da dieser Druck im Bereich der Verzweigungen der Eingänge der ist, der für den Betrieb sämtlicher an das Abluftzentralsystem angeschlossenen Elemente und Maschinen von Bedeutung ist.In this case, the pressure to be generated under a maximum value is preferably measured with a pressure measuring device which is provided in the region of the branches of the entrances of the exhaust air central system, since this pressure in the region of the branches of the inputs is the, for the operation of all connected to the exhaust air central system elements and Machinery is important.

Das Fördersystem, welches die Abluft erzeugt, ist dabei vorzugsweise so ausgelegt, dass es Fördereinheiten aufweist, an die die Tabakprodukte oder Tabakzwischenprodukte zu deren Beförderung durch Unterdruck angesaugt werden. Hierfür weisen die Fördereinheiten vorzugsweise luftdurchlässig gestaltete Anlageflächen auf, die vorzugsweise eine an das jeweils zu befördernde Tabakprodukt oder Tabakzwischenprodukt angepasste Kontur aufweisen. Die Tabakprodukte bzw. Tabakzwischenprodukte können so durch abwechselndes Aufschalten des Unterdrucks auf die einzelnen Fördereinheiten von der Anlagefläche der einen Fördereinheit zur Anlagefläche der nächsten Fördereinheit weitergegeben werden. Eine bevorzugte Ausbildung der Fördereinheiten ist dabei deren Konstruktion als vorzugsweise rotierende Trommeln oder trommelartige Gebilde.The conveyor system that generates the exhaust air is preferably designed so that it has conveyor units to which the tobacco products or tobacco intermediates are sucked to their promotion by negative pressure. For this purpose, the conveyor units preferably air-permeable designed contact surfaces, which preferably have a matched to the respectively to be transported tobacco product or tobacco intermediate contour. The tobacco products or tobacco intermediates can be passed by alternately switching the negative pressure on the individual conveyor units from the contact surface of a conveyor unit to the contact surface of the next conveyor unit. A preferred embodiment of the conveyor units is their construction as preferably rotating drums or drum-like structures.

Zur Förderung der Abluft der pneumatischen Fördereinrichtung des Filteransetzers sind vorzugsweise eine oder mehrere Fördereinrichtungen, beispielsweise ein oder mehrere Verdichter, vorgesehen. Ein derartiger Verdichter kann den Unterdruck in dem pneumatischen Fördersystem unter den Wert des Unterdrucks im Abluftzentralsystem absenken. Dabei kann die Fördereinrichtung insbesondere im Gehäuse des Filteransetzers integriert sein.To promote the exhaust air of the pneumatic conveyor of the Filteransetzers preferably one or more conveyors, for example, one or more compressors are provided. Such a compressor can lower the negative pressure in the pneumatic conveying system below the value of the negative pressure in the exhaust air central system. In this case, the conveyor may be integrated in particular in the housing of the filter tappet.

Um eine geeignete Richtgröße für die Regelung zu erhalten, weist die Regelungsanordnung vorzugsweise eine Messeinrichtung zur Messung des Massen- und/oder Volumenstroms auf. Sowohl Massen- als auch Volumenstrom sind geeignete Richtgrößen für eine derartige Regelung, wobei der Massenstrom den Vorteil hat, bei konstanter chemischer Zusammensetzung der geförderten Luft direkt proportional zu deren Stoffmengenstrom zu sein, jedoch kann es im Rahmen der Integration in die Regelung bzw. aufgrund der messtechnischen Gegebenheiten einfacher sein, den Volumenstrom zu ermitteln. Dieser ist zwar nicht direkt proportional zu dem Mengenstrom, erlaubt jedoch bei den vorliegenden Randbedingungen hinsichtlich Temperatur und Druckschwankungen in diesem Fall eine ausreichend genaue Regelung und kann hierdurch vorteilhaft sein.In order to obtain a suitable reference variable for the control, the control arrangement preferably has a measuring device for measuring the mass flow and / or volumetric flow. Both mass flow and volume flow are suitable benchmarks for such control, the mass flow having the advantage of being more constant chemical composition of the transported air to be directly proportional to their molar flow, but it may be easier to determine the flow rate in the context of integration into the scheme or due to the metrological conditions. Although this is not directly proportional to the flow rate, but allows in the present boundary conditions with respect to temperature and pressure fluctuations in this case, a sufficiently accurate control and can be advantageous thereby.

Als Stellglied kann die Fördereinrichtung vorteilhafterweise eine Drosselklappe bzw. eine ähnliche Drosseleinrichtung als Stellglied aufweisen, alternativ ist es jedoch ebenfalls möglich, eine unter Umständen vorhandene, dem Filteransetzer zugeordnete Fördereinrichtungen direkt beispielsweise über eine Drehzahlregelung anzusteuern, was sich insbesondere bei der Verwendung volumetrischer Fördereinrichtung anbietet.As an actuator, the conveyor may advantageously have a throttle or a similar throttle device as an actuator, alternatively, it is also possible to control a possibly existing, the filter piecing associated conveyors directly, for example via a speed control, which is particularly useful when using volumetric conveyor.

Die Erfindung wird im Folgenden anhand der Figur 1, die eine schematische Darstellung einer erfindungsgemäßen Regelungsanordnung in einem Zigarettenherstellungsprozess zeigt, erläutert.The invention will be described below with reference to the FIG. 1 , which shows a schematic representation of a control arrangement according to the invention in a cigarette manufacturing process explained.

Der Filteransetzer 1 ist an das zentrale Abluftsystem 7 angeschlossen. Das Abluftzentralsystem 7 weist dabei als zentrale Elemente beispielhaft einen zentralen Filter 7b und einen an dessen Ausgang angeordneten zentralen Abluftförderer 7c auf. Im Bereich der Verzweigungen 7a vereinigen sich die Abluftströme des Filteransetzers 1 und die weiterer, nur in Form ihrer Abluftströme dargestellten Maschinen 8.The filter attachment 1 is connected to the central exhaust air system 7. The exhaust air central system 7 has as central elements, for example, a central filter 7b and a central exhaust air conveyor 7c arranged at its exit. In the area of the branches 7a, the exhaust air streams of the filter tappet 1 and the other machines 8, which are shown only in the form of their exhaust air streams, are combined.

Der beispielhafte Filteransetzer 1 weist ein Fördersystem auf, welches die rotierenden Fördereinheiten 2a umfasst, an die die zu befördernden Tabakprodukte bzw. Tabakzwischenprodukte 10 durch Unterdruck angesaugt und beim Transport jeweils von der einen in die andere Fördereinrichtung übergeben werden. Die Abluft aus den einzelnen Fördereinheiten 2a wird vereinigt den Fördereinrichtungen 3 zugeführt, die hier beispielhaft im Inneren des Filteransetzers 1 angeordnet sind. Der von der Fördereinrichtung 3 in das Abluftzentralsystem 7 geförderte Abluft-strom wird durch eine erfindungsgemäße Regelungsanordnung geregelt, die beispielhaft die Messeinrichtung 4 zur Ermittlung des Prozessluftmengenstroms und die Drosseleinrichtung 5 als Stellglied aufweist. Alternativ kann die Regelung statt auf die Drosseleinrichtung 5 auch direkt auf die Luftfördereinrichtungen 3 einwirken. Vorteilhafterweise ist die Regelungsanordnung dabei derart angesteuert, dass im Bereich der Verzweigungen 7a der dahinter liegenden vereinigten Luftströme 9 bzw. dem unmittelbar zur Verzweigung 7a führenden Luftstrom 8 ein Höchstdruck nicht überschritten wird, um auch bei gravierenden Betriebszustandsänderungen im Filteransetzer 1 den reibungslosen Betrieb der weiteren an das Abluftzentralsystem angeschlossenen Maschinen 6 zu gewährleisten.The exemplary filter tappet 1 has a conveyor system, which comprises the rotating conveyor units 2 a, to which the tobacco products or tobacco intermediates 10 to be transported are sucked in by vacuum and transferred from one to the other conveyor during transport. The exhaust air from the individual conveyor units 2a is combined fed to the conveying means 3, which are arranged here for example in the interior of the filter tappet 1. The exhaust air flow conveyed by the delivery device 3 into the exhaust air central system 7 is regulated by a control arrangement according to the invention, which for example has the measuring device 4 for determining the process air mass flow and the throttle device 5 as an actuator. Alternatively, the control can also act directly on the air conveying devices 3 instead of the throttle device 5. Advantageously, the control arrangement is controlled in such a way that a maximum pressure is not exceeded in the region of the branches 7a of the underlying air streams 9 or the air stream 8 leading directly to the branch 7a, in order to ensure trouble-free operation of the further even in the event of serious changes in operating state in the filter tappet 1 To ensure the exhaust air central system connected machines 6.
