Description
Die vorliegende Erfindung betrifft eine Anordnung mehrerer zumindest materialflusstechnisch miteinander gekoppelter Maschinenbaugruppen mit den Merkmalen des unabhängigen Anspruchs 1. Die Erfindung betrifft weiterhin ein Verfahren mit den Merkmalen des unabhängigen Verfahrensanspruchs 7 zur Koppelung mehrerer Maschinenbaugruppen, die aufeinander folgende Behandlungs- und/oder Verarbeitungsstationen einer Maschine zur Verarbeitung, Behandlung und/oder Abfüllung von Behältern bilden.The present invention relates to an arrangement of several at least material flow technology coupled machine assemblies with the features of independent claim 1. The invention further relates to a method with the features of the independent method claim 7 for coupling a plurality of machine assemblies, the successive treatment and / or processing stations of a machine for Processing, treatment and / or filling of containers form.
Bei bekannten Behälterbehandlungs- und Verpackungsmaschinen wird an unterschiedlichen Stellen Druckluft eingesetzt. So ist bspw. in einer Behälterbehandlungsmaschine, die ein Verpackungsmodul mit Folieneinschlag umfasst, der Einsatz von Druckluft im Bereich der Folienführung üblich, um den korrekten Folientransport zu gewährleisten. So wird innerhalb einer Folientrennstation die zugeschnittene Folie normalerweise über ein Band in Richtung eines weiteren Transportbandes einer Folieneinschlagstation befördert. Das Förderband der Folientrennstation wird meist mittels eines Gebläses mit Unterdruck beaufschlagt. Im weiteren Verlauf muss die Folie über einen Bereich geschoben werden, in dem keine Auflage der Folie gewährleistet werden kann. Zur Überbrückung dieses Bereichs und um zu verhindern, dass die Folie bzw. der Folienanfang schwerkraftbedingt nach unten oder oben abgelenkt wird, kann zur Beförderung der Folie mittels Unterstützung von Blasdüsen ein Luftkanal gebildet sein. Sowohl der für das Förderband der Folientrennstation erforderliche Unterdruck als auch der für den luftunterstützten Folientransport im weiteren Verlauf benötigte Überdruck bedingen einen relativ hohen Druckluftverbrauch. Zudem sind beide Systeme abhängig von der Aufrechterhaltung des Systemdrucks der Druckluftversorgung.In known container treatment and packaging machines compressed air is used at different points. Thus, for example, in a container treatment machine comprising a packaging module with film wrapping, the use of compressed air in the area of the film guide is customary in order to ensure the correct film transport. Thus, within a film separation station, the cut film is normally conveyed over a belt in the direction of another conveyor belt of a film wrapping station. The conveyor belt of the film separation station is usually subjected to negative pressure by means of a blower. In the further course, the film must be pushed over an area in which no support of the film can be guaranteed. To bridge this area and to prevent the film or the film beginning is deflected by gravity down or up, an air channel can be formed for the promotion of the film by means of support of blowing nozzles. Both the vacuum required for the conveyor belt of the film separating station and the overpressure required for the air-assisted film transport in the further course require a relatively high consumption of compressed air. In addition, both systems are dependent on maintaining the system pressure of the compressed air supply.
Ein vorrangiges Ziel der vorliegenden Erfindung besteht daher darin, durch Umlenkung und/oder anderweitige Nutzung der Abluft von vorhandenen Gebläsen und/oder Unterdruckquellen eine verbesserte Energiebilanz einer Behälterbehandlungsanlage zu erzielen und ungenutzte Anteile an Druckluft und damit zuvor aufgewendeter Energie zu reduzieren.A primary objective of the present invention is therefore to achieve an improved energy balance of a container treatment plant by diversion and / or other use of the exhaust air from existing fans and / or vacuum sources and to reduce unused portions of compressed air and thus previously used energy.
Dieses Ziel der Erfindung wird mit den Gegenständen der unabhängigen Ansprüche erreicht. Merkmale vorteilhafter Weiterbildungen der Erfindung ergeben sich aus den abhängigen Ansprüchen.This object of the invention is achieved with the objects of the independent claims. Features of advantageous developments of the invention will become apparent from the dependent claims.
Zur Erreichung des genannten Ziels schlägt die Erfindung eine Anordnung mehrerer zumindest materialflusstechnisch miteinander gekoppelter Maschinenbaugruppen vor, die aufeinander folgende Behandlungs- und/oder Verarbeitungsstationen einer Maschine zur Verarbeitung, Behandlung, Abfüllung und/oder Verpackung von Behältern bilden, welche Maschinenbaugruppen jeweils Komponenten zur Luftführung, zur Luftkühlung und/oder Druckluftversorgung aufweisen, wobei wenigstens eine der Maschinenbaugruppen mit Abluft einer der weiteren Maschinenbaugruppen gespeist ist. Die Maschinenbaugruppen können bspw. Teile bzw. Module einer Behälterformungsanlage sein, der eine Abfüllanlage und eine Verpackungsanlage nachgeordnet sind. Bei verschiedenen Maschinenteilen wird Druckluft als Energiequelle und/oder zur Unterstützung der Materialförderung, bspw. beim Folientransport eingesetzt, die normalerweise verbraucht und ohne weitere Nutzung in die Umgebung abgegeben wird. Der Einsatz von Druckluft bedingt deshalb generell einen relativ hohen Energieverbrauch, der mit Hilfe der Erfindung reduziert werden kann, wenn die Maschinenteile nicht nur materialflusstechnisch, sondern auch energetisch miteinander gekoppelt werden. Hierzu wird vorgeschlagen, die Druckluftversorgungen zumindest teilweise modulübergreifend einzusetzen, insbesondere durch Nutzung der Abluft, die bei einzelnen Modulen entstehen, zur Verwendung in wenigstens einem weiteren Modul.In order to achieve the stated object, the invention proposes an arrangement of a plurality of at least material flow-coupled machine assemblies, which form successive treatment and / or processing stations of a machine for processing, handling, filling and / or packaging of containers, which machine assemblies each comprise components for air guidance, for air cooling and / or compressed air supply, wherein at least one of the machine assemblies is fed with exhaust air of the other machine assemblies. The machine assemblies may be, for example, parts or modules of a container forming plant, which are arranged downstream of a bottling plant and a packaging plant. In various machine parts compressed air is used as an energy source and / or to support the material promotion, eg. When film transport, which is normally consumed and released into the environment without further use. Therefore, the use of compressed air generally requires a relatively high energy consumption, which can be reduced with the help of the invention, when the machine parts are coupled not only material flow technology, but also energetically coupled to each other. For this purpose, it is proposed to use the compressed air supplies at least partially across modules, in particular by using the exhaust air produced at individual modules, for use in at least one other module.
So kann vorgesehen sein, die von wenigstens einer der Maschinenbaugruppen gelieferte Abluft als Druckluftversorgung und/oder Kühlluftversorgung von Maschinenkomponenten und/oder Teilen der Behälter und/oder deren Verpackungsmittel wenigstens einer weiteren Maschinenbaugruppe einzusetzen. Eine sinnvolle Variante einer solchen Koppelung kann bspw. darin bestehen, dass die mit Abluft versorgte Maschinenbaugruppe eine Folienschrumpfstation ist, die eine Fördereinrichtung zum Transport von mit Folie umhüllten Gebinden mit mehreren Behältern aufweist. Bei den Folienschrumpfstationen tritt oftmals das Problem auf, dass die Förderketten für die mit Folie umhüllten Gebinde permanent zyklisch erhitzt werden und deshalb vor ihrem Erstkontakt mit einem neuen Gebinde gekühlt werden müssen, damit die Verpackungsfolie an dieser Stelle nicht zu weich wird und an der Förderkette haftet oder dort verklebt.Thus, it can be provided to use the exhaust air supplied by at least one of the machine assemblies as compressed air supply and / or cooling air supply of machine components and / or parts of the containers and / or their packaging means of at least one further machine assembly. An expedient variant of such a coupling may, for example, be that the machine assembly supplied with exhaust air is a film shrinking station which has a conveying device for transporting foil-enclosed containers with a plurality of containers. In the case of film shrinking stations, the problem often arises that the conveyor chains for the film-wrapped containers are permanently heated cyclically and must therefore be cooled before their first contact with a new container so that the packaging film does not become too soft at this point and sticks to the conveyor chain or glued there.
Die erfindungsgemäße Anordnung kann deshalb durch eine Variante gebildet sein, bei der die Fördereinrichtung eine umlaufende Förderkette ist, die permanent durch die Folienschrumpfstation läuft und dort durch Heißluftbeaufschlagung der mit Folie umhüllten Gebinde erwärmt und in einem außerhalb des Folienschrumpfbereichs mit der Abluft einer der benachbarten Maschinenbaugruppen gekühlt wird. Auf diese Weise wird die Förderkette effektiv gekühlt, ohne dass ein zusätzlicher Energieverbrauch durch Erzeugung dieser kühlenden Luft damit verbunden ist.The arrangement according to the invention can therefore be formed by a variant in which the conveyor is a circulating conveyor chain which runs permanently through the film shrinking station and heated there by Heißluftbeaufschlagung the film-wrapped container and cooled in a outside of the film shrinkage area with the exhaust air of one of the adjacent machine assemblies becomes. In this way, the conveyor chain is effectively cooled, without any additional energy consumption associated with producing this cooling air.
Eine weitere sinnvolle Variante der Erfindung kann vorsehen, dass zwischen benachbarten und miteinander gekoppelten Maschinenbaugruppen eine Einrichtung zur Zwischenkühlung der zwischen den Baugruppen ausgetauschten Abluft angeordnet ist. Dies kann besonders dann sinnvoll sein, wenn die Abluft für ihren weiteren Einsatz als Kühlluft in ihrer Temperatur reduziert werden soll. Der energetische Vorteil ist auch hierbei noch uneingeschränkt gegeben, da die meiste Energie für die Herstellung der Druckluft aufzuwenden ist, wogegen die Zwischenkühlung nur einen relativ geringen zusätzlichen Energieeinsatz erfordert.Another useful variant of the invention can provide that a device for intermediate cooling of the exchanged between the modules exhaust air is arranged between adjacent and coupled together machine assemblies. This can be particularly useful if the exhaust air is to be reduced in their temperature for their further use as cooling air. The energetic advantage is here also unrestricted, since most of the energy is spent on the production of compressed air, whereas the intermediate cooling requires only a relatively small additional energy input.
Wahlweise oder zusätzlich kann auch zwischen benachbarten und miteinander gekoppelten Maschinenbaugruppen eine Einrichtung zur Druckerhöhung der zwischen den Baugruppen ausgetauschten Abluft angeordnet sein. Eine solche Einrichtung zur Druckerhöhung kann bspw. durch einen geeigneten Verdichter, bspw. einen Turboverdichter o. dgl. gebildet sein.Alternatively or additionally, a device for increasing the pressure of the exchanged between the modules exhaust air can also be arranged between adjacent and coupled together machine assemblies. Such a device for increasing the pressure can be formed, for example, by a suitable compressor, for example a turbo-compressor or the like.
Die Erfindung umfasst neben den zuvor beschriebenen Varianten einer Anordnung von gekoppelten Maschinenbaugruppen auch ein Verfahren zur energetischen Koppelung mehrerer Maschinenbaugruppen, die aufeinander folgende Behandlungs- und/oder Verarbeitungsstationen einer Maschine zur Verarbeitung, Behandlung, Abfüllung und/oder Verpackung von Behältern bilden, welche Maschinenbaugruppen jeweils Komponenten zur Luftführung, zur Luftkühlung und/oder Druckluftversorgung aufweisen, wobei wenigstens eine der Maschinenbaugruppen mit Abluft einer der weiteren Maschinenbaugruppen gespeist wird. Auf diese Weise wird nicht nur eine materialflusstechnische Koppelung der Maschinenbaugruppen erreicht, sondern auch eine energetische Koppelung, da aufgrund der Nutzung der an einem Maschinenmodul anfallenden Abluft als Kühlluft und/oder als Teil einer Druckluftversorgung zumindest teilweise auf die energetisch aufwändige Herstellung der Kühlluft und/oder Druckluft an diesem angeschlossenen Modul verzichtet werden kann. Eine vorteilhafte Variante des erfindungsgemäßen Verfahrens sieht deshalb vor, die von wenigstens einer der Maschinenbaugruppen gelieferte Abluft zur Druckluftversorgung und/oder Kühlluftversorgung von Maschinenkomponenten und/oder Teilen der Behälter und/oder deren Verpackungsmittel zu verwenden und zu einer weiteren Maschinenbaugruppe zu leiten.In addition to the previously described variants of an arrangement of coupled machine assemblies, the invention also encompasses a method for the energetic coupling of a plurality of machine assemblies, which form successive treatment and / or processing stations of a machine for processing, treating, filling and / or packaging containers, which machine assemblies respectively Have components for air flow, air cooling and / or compressed air supply, wherein at least one of the machine assemblies is fed with exhaust air of the other machine assemblies. In this way, not only a material flow technology coupling of the machine assemblies is achieved, but also an energetic coupling, as due to the use of accumulating on a machine module exhaust air as cooling air and / or as part of a compressed air supply at least partially on the energetic complex production of cooling air and / or Compressed air can be dispensed with at this connected module. An advantageous variant of the method according to the invention therefore provides for the exhaust air supplied by at least one of the machine assemblies to be used for supplying compressed air and / or cooling air to machine components and / or parts of the containers and / or their packaging means and to route them to a further machine assembly.
Die mit Abluft versorgte Maschinenbaugruppe kann bspw. eine Folienschrumpfstation sein, die eine Fördereinrichtung zum Transport von mit Folie umhüllten Gebinden mit mehreren Behältern aufweist. Diese Fördereinrichtung kann insbesondere durch eine umlaufende Förderkette gebildet sein, die permanent durch die Folienschrumpfstation läuft und dort durch Heißluftbeaufschlagung der mit Folie umhüllten Gebinde erwärmt und in einem außerhalb des Folienschrumpfbereichs mit der Abluft einer der benachbarten Maschinenbaugruppen gekühlt wird. Bei diesen Förderketten entsteht oftmals das Problem, dass durch die permanente Erwärmung innerhalb des Schrumpftunnels ein permanenter Wärmeeintrag erfolgt, der zur einer Temperaturerhöhung führt, die nach einiger Betriebsdauer zu hoch für die mit der Förderkette in Kontakt kommenden Schrumpffolie wird, so dass sich diese bereits vor dem Durchlaufen des Schrumpftunnels stark erwärmt, dadurch erweicht und unter ungünstigen Umständen mit der Förderkette verkleben kann.The machine assembly supplied with exhaust air may, for example, be a film shrinking station which has a conveying device for transporting foil-enclosed containers with a plurality of containers. This conveyor may in particular be formed by a circulating conveyor chain, which runs permanently through the film shrinking station where it is heated by Heißluftbeaufschlagung the film-wrapped container and cooled in a outside of the film shrinkage area with the exhaust air of one of the adjacent machine assemblies. In these conveyor chains often the problem arises that the permanent heating within the shrink tunnel permanent heat input takes place, which leads to a temperature increase, which is too high for some operating time for the coming into contact with the conveyor chain shrink film, so that they already before greatly warmed by passing through the shrink tunnel, thereby softened and can stick under unfavorable circumstances with the conveyor chain.
Wahlweise kann die zwischen benachbarten und miteinander gekoppelten Maschinenbaugruppen ausgetauschte Abluft zwischengekühlt und/oder ihr Förderdruck erhöht werden. Die Zwischenkühlung ist besonders dann sinnvoll, wenn die Temperatur der Abluft für die Verwendung als Kühlluft noch zu hoch ist. Der Förderdruck kann bspw. mittels zwischengeschalteter Turbo- oder Radialverdichter o. dgl. erhöht werden, wenn für die erneute Nutzung der Abluft ein höherer Förderdruck oder eine größere Luftgeschwindigkeit benötigt werden sollte.Optionally, the exhaust air exchanged between adjacent and coupled machine assemblies may be intercooled and / or their discharge pressure increased. The intermediate cooling is particularly useful if the temperature of the exhaust air for use as cooling air is still too high. The delivery pressure can be increased, for example, by means of interposed turbo or radial compressor o. The like., If for the reuse of the exhaust air, a higher discharge pressure or a greater air speed should be required.
Die vorliegende Erfindung liefert eine Möglichkeit zur Reduzierung des Energieverbrauchs in einer Behälterbehandlungsmaschine, die über mehrere miteinander gekoppelte und materialflusstechnisch verbundene Stationen bzw. Module verfügt. So ist bspw. bei einer Folienführung der Einsatz von Druckluft erforderlich, um den korrekten Folientransport zu gewährleisten. So wird innerhalb einer Folientrennstation die zugeschnittene Folie normalerweise über ein Band in Richtung eines weiteren Transportbandes einer Folieneinschlagstation befördert. Das Förderband der Folientrennstation wird meist mittels eines Gebläses mit Unterdruck beaufschlagt. Im weiteren Verlauf muss die Folie über einen Bereich geschoben werden, in dem keine Auflage der Folie gewährleistet werden kann. Zur Überbrückung dieses Bereichs und um zu verhindern, dass die Folie bzw. der Folienanfang schwerkraftbedingt wegknickt, ist es üblich, zur Beförderung der Folie mittels einer Unterstützung von Blasdüsen einen Luftkanal zu erzeugen, was auch als sog. "Luftbettförderung" bekannt ist. Sowohl der für das Förderband der Folientrennstation erforderliche Unterdruck als auch der für den luftunterstützten Folientransport im weiteren Verlauf benötigte Überdruck bedingen einen relativ hohen Druckluftverbrauch. Zudem sind beide Systeme abhängig von der Aufrechterhaltung des Systemdrucks der Druckluftversorgung. Dagegen wurde die vom Gebläse erzeugte Abluft bisher ungenutzt an die Umgebung abgegeben. Ein Aspekt der vorliegenden Erfindung betrifft die Nutzung der Abluft des bereits vorhandenen Gebläses in der Folientrennstation. So kann die Gebläseabluft bspw. an die Blasdüsen oder -rohre der Folientrennstation angeschlossen werden und somit die bisher verwendete Druckluft zumindest teilweise ersetzen. Darüber hinaus kann die Gebläseabluft auch an die Blasdüsen oder -rohre einer Folienspreizung angeschlossen werden und auch dort die bisher verwendete Druckluft zumindest teilweise ersetzen. Ggf. kann es für diese genannten Einsatzfälle notwendig sein, den Druck der Abluft des Gebläses zu erhöhen, was bspw. mittels eines Turbogebläses oder Kompressors realisiert werden kann. Sinnvoll wäre darüber hinaus auch die Anpassung der Gebläsedimensionierung an die gesamte verbrauchte Druckluft, inklusive der in der Folientrennstation und/oder der Folienspreizung benötigten Abluft.The present invention provides a way to reduce energy consumption in a container treatment machine having a plurality of interconnected and material flow associated stations or modules. For example, in the case of a film guide, the use of compressed air is necessary in order to ensure the correct transport of the film. Thus, within a film separation station, the cut film is normally conveyed over a belt in the direction of another conveyor belt of a film wrapping station. The conveyor belt of the Folientrennstation is usually acted upon by means of a fan with negative pressure. In the further course, the film must be pushed over an area in which no support of the film can be guaranteed. To bridge this area and to prevent the film or the beginning of the film from buckling due to gravity, it is customary to produce an air channel for conveying the film by means of a support of blowing nozzles, which is also known as so-called "air bed conveying". Both the vacuum required for the conveyor belt of the film separating station and the overpressure required for the air-assisted film transport in the further course require a relatively high consumption of compressed air. In addition, both systems are dependent on maintaining the system pressure of the compressed air supply. By contrast, the exhaust air generated by the fan was previously released unused to the environment. One aspect of the present invention relates to the use of the exhaust air of the existing blower in the film separating station. For example, the blower exhaust air can be connected to the blowing nozzles or pipes of the film separating station and thus at least partially replace the previously used compressed air. In addition, the blower exhaust air can also be connected to the tuyeres or pipes of a spread of film and there replace the previously used compressed air at least partially. Possibly. It may be necessary for these applications mentioned to increase the pressure of the exhaust air of the blower, which can be realized, for example, by means of a turbo blower or compressor. It would also make sense to adapt the fan dimensioning to the total compressed air used, including the exhaust air required in the film separation station and / or the film spreading.
Eine besonders vorteilhafte Variante besteht jedoch in der Verwendung der weitgehend drucklosen Abluft ohne Berücksichtigung eines ggf. noch vorhandenen Restdrucks zur Kühlung anderer Komponenten, da es hierbei im Wesentlichen auf den verfügbaren Volumenstrom der Abluft ankommt, ohne dass auf die Druckverhältnisse besondere Rücksicht genommen werden muss. Hierfür kommt insbesondere die Kühlung der Förderketten in der Schrumpfstation bzw. im Schrumpftunnel in Frage, da in diesem Bereich der permanente Wärmeeintrag in die Kette aufgrund der die Folie um die Gebinde fixierenden Heißluft meist mit einer signifikanten Erwärmung der Förderketten einhergeht, was zu Problemen beim Kontakt mit der Folie führen kann. Aus diesem Grund müssen diese Förderketten normalerweise gekühlt werden, was besonders vorteilhaft mit der von anderen Stationen gelieferten Abluft erfolgen kann.However, a particularly advantageous variant consists in the use of largely unpressurized exhaust air without consideration of any residual pressure remaining for cooling other components, since it essentially depends on the available volume flow of exhaust air, without having to take special account of the pressure conditions. For this purpose, in particular the cooling of the conveyor chains in the shrinking station or in the shrink tunnel in question, since in this area the permanent heat input into the chain due to the film fixing the container hot air usually accompanied by a significant heating of the conveyor chains, causing problems in contact can lead with the film. For this reason, these conveyor chains must normally be cooled, which can be done particularly advantageous with the exhaust air supplied by other stations.
