Abstract
Description
Die vorliegende Erfindung betrifft eine Vorrichtung zur Trocknung von Gegenständen, insbesondere von Flüssigkeitsbehältern, mit den Merkmalen des Oberbegriffs des Anspruchs 1. Die Erfindung betrifft zudem ein entsprechendes Verfahren mit den Merkmalen des Oberbegriffs des Anspruchs 13.The present invention relates to a device for drying articles, in particular liquid containers, with the features of the preamble of claim 1. The invention also relates to a corresponding method having the features of the preamble of claim 13.
Bei Anlagen zum Abfüllen und Etikettieren von Flaschen herrscht in der Regel eine gewisse Feuchtigkeit vor, die nach dem Befüllen der Flaschen an deren Außenseite anhaften kann. Auch nach dem Waschen der Flaschen können Flüssigkeitsreste innen und/oder außen an den Flaschen verbleiben.In systems for bottling and labeling bottles usually prevails some moisture that can adhere to the outside after filling the bottles. Even after washing the bottles, liquid residues may remain on the inside and / or outside of the bottles.
Bei einer optischen Inspektion der Flaschen auf ihre mechanische Unversehrtheit und/oder auf das Vorhandensein von Fremdstoffen wie bspw. Verunreinigungen oder Glassplitter können derartige Flüssigkeitsreste als Tropfen zu erheblichen Beeinträchtigungen der optischen Abbildungsqualität führen, weshalb es günstiger ist, nur möglichst trockene Flaschen einer optischen Untersuchung zu unterziehen.In the case of an optical inspection of the bottles for their mechanical integrity and / or for the presence of foreign substances such as impurities or glass splinters, such liquid residues as drops can lead to considerable impairment of the optical imaging quality, which is why it is better to only dry the bottles if possible for optical examination undergo.
Bekannte Trocknungsanlagen für Flaschen umfassen einen oder mehrere nacheinander angeordnete kastenförmige Räume, durch die ein Förderband mit aufrecht stehenden Flaschen läuft. Innerhalb des Raums sorgen mehrere Luftdüsen für ein Abblasen von Restfeuchtigkeit an den Flaschenaußenseiten und damit für die Gewährleistung trockener Flaschen nach dem Verlassen der Trocknungsanlage. Die für die Trocknung benötigen Luftmengen werden durch ein leistungsfähiges Gebläse zur Verfügung gestellt, das Außenluft ansaugt und zu den Düsen leitet. Der innerhalb der jeweiligen Räume der Trocknungsanlage herrschende Überdruck kann durch mehrere Öffnungen entweichen, insbesondere durch die beiden Öffnungen zur Flaschenzufuhr und Flaschenabfuhr, die durch die Platzierung des Förderbandes definiert sind. Da für die Speisung der Luftdüsen erhebliche Luftmengen benötigt werden, entweicht der Überdrück mit relativ großen Luftgeschwindigkeiten. Die abströmende Luft und das schnell laufende Gebläse sorgen für eine erhebliche Lärmentwicklung.Known drying plants for bottles comprise one or more successively arranged box-shaped spaces through which a conveyor belt with upright bottles passes. Inside the room, several air jets provide for the removal of residual moisture on the outside of the bottle, thus guaranteeing dry bottles after leaving the drying plant. The air volumes required for drying are provided by a powerful blower that draws in outside air and directs it to the nozzles. The prevailing within the respective rooms of the drying plant overpressure can escape through several openings, in particular through the two openings for bottle feeding and bottle removal, which are defined by the placement of the conveyor belt. As for the Supplying the air nozzles considerable amounts of air are needed, escaping the overpressure with relatively high air velocities. The outflowing air and the high-speed fan ensure a considerable amount of noise.
Das Ziel der Erfindung besteht darin, bei einer Anlage zur Trocknung von Gegenständen wie Getränkebehältern oder Flaschen die Schallemissionen zu reduzieren.The object of the invention is to reduce the noise emissions in a system for drying objects such as beverage containers or bottles.
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.
Bei der genannten Erfindung handelt es sich um eine Vorrichtung zur Trocknung von Gegenständen, die insbesondere als Flaschentrocknungsanlage ausgebildet sein kann. Die Anlage umfasst ein weitgehend geschlossenes Gehäuse mit wenigstens einer Kammer. Zur Trocknung der Gegenstände bzw. Flaschen werden diese mittels eines Förderbandes durch das Gehäuse befördert und innerhalb des Gehäuse mittels Luftdüsen mit Druckluft bzw. mit stark beschleunigter Luft beaufschlagt. Für das Förderband mit den darauf beförderten Flaschen oder anderen Gegenständen sind Ein- und Ausgangöffnungen vorgesehen. Es ist zudem mindestens eine Luftzuführöffnung zur Zuführung von Trocknungsluft und mindestens eine Abluftöffnung zur Abführung der Trocknungsluft aus dem Gehäuse vorhanden. Gemäß der vorliegenden Erfindung ist eine innere Luftführung im Gehäuse gebildet, die zur Erzeugung einer definierten Luftabfuhr zur mindestens einen Abluftöffnung dient. Die innere Luftführung verläuft dabei im Wesentlichen an der Ein- und/oder Ausgangsöffnung für die zu trocknenden Gegenstände vorbei. Die gerichtete Luftströmung sorgt dafür, dass durch die Ein- und Ausgangsöffnungen möglichst wenig Luft entweicht, so dass auf diese Weise der durch die Ein- und Ausgangsöffnungen transportierte Luftschall deutlich reduziert ist.In the aforementioned invention is a device for drying of articles, which may be designed in particular as a bottle drying system. The system comprises a largely closed housing with at least one chamber. To dry the objects or bottles they are conveyed by a conveyor belt through the housing and pressurized within the housing by means of air nozzles with compressed air or with greatly accelerated air. For the conveyor belt with the bottles or other objects carried thereon, entry and exit openings are provided. There is also at least one air supply opening for supplying drying air and at least one exhaust air opening for discharging the drying air from the housing. According to the present invention, an inner air duct is formed in the housing, which serves to generate a defined air discharge to at least one exhaust air opening. The inner air duct runs essentially past the inlet and / or outlet opening for the objects to be dried. The directed air flow ensures that as little air escapes through the inlet and outlet openings, so that in this way the airborne sound transported through the inlet and outlet openings is significantly reduced.
Gemäß einer bevorzugten Ausgestaltung der Erfindung ist die wenigstens eine Abluftöffnung als Luftabfuhrkanal ausgebildet, durch den die Luft aus dem Gehäuse abgeführt wird. Durch Ausbildung eines derartigen Luftabfuhrkanals können gezielte Schalldämpfungsmaßnahmen vorgesehen werden. Zudem kann eine effektive Schalldämmung mit einem relativ geringen baulichen Aufwand realisiert werden. So kann der Luftabfuhrkanal insbesondere als Reflexions- und/oder Absorptionsdämpfer ausgebildet sein. Zu diesem Zweck können im Luftabfuhrkanal schalldämpfende Elemente angeordnet sein. Grundsätzlich können die schalldämpfenden Elemente nahezu beliebige Ausgestaltungen aufweisen, wie sie aus dem Bereich der Maschinenakustik bekannt und verfügbar sind. Eine besonders einfache und kostengünstige Maßnahme kann darin bestehen, als schalldämpfendes Element wenigstens eine schräg zur Kanallängsrichtung angeordnete strukturierte Platte mit Metallwolle anzuordnen. Wahlweise können zwei oder mehr derartige schräg zur Kanallängsrichtung angeordnete strukturierte Platten im Luftabfuhrkanal nacheinander angeordnet sein. An diesen strukturierten Platten wird der Schall teilweise absorbiert und teilweise reflektiert, wobei er stark gestreut wird.According to a preferred embodiment of the invention, the at least one exhaust air opening is formed as an air discharge channel, through which the air is discharged from the housing. By designing such an air discharge channel targeted soundproofing measures can be provided. In addition, an effective sound insulation can be realized with a relatively low construction cost. Thus, the air discharge channel may be formed in particular as a reflection and / or absorption damper. For this purpose, sound-damping elements can be arranged in the air discharge channel. Basically, the sound-absorbing elements can have almost any configuration, as they are in the field of Machine acoustics are known and available. A particularly simple and cost-effective measure can be to arrange at least one obliquely arranged to the channel longitudinal direction structured plate with metal wool as a sound-absorbing element. Optionally, two or more such obliquely arranged to the channel longitudinal direction structured plates in the air discharge channel may be arranged one after the other. On these structured plates the sound is partially absorbed and partially reflected, whereby it is strongly scattered.
Die Schalldämpfung kann dadurch unterstützt werden, indem die Innenwände des Luftabfuhrkanals strukturiert sind und/oder mit schalldämpfendem Material ausgekleidet sind. Als strukturierte Platten können bspw. Gitterflächen mit großer Maschenweite und dahinter angeordneter Metall- oder Mineralwolle verwendet werden. Besonders geeignet als schalldämpfendes Material ist Edelstahlwolle, da hierbei keine nennenswerte Korrosion auftritt, so dass auch hohe hygienische Anforderungen im Dauerbetrieb erfüllt werden können.The sound attenuation can be supported by the inner walls of the air discharge channel are structured and / or lined with sound-absorbing material. For example, grid surfaces with a large mesh size and metal or mineral wool arranged behind them can be used as structured plates. Stainless steel wool is particularly suitable as a sound-damping material, since no appreciable corrosion occurs, so that even high hygienic requirements can be met in continuous operation.
Die Luftströmung durch den Luftabfuhrkanal kann durch zusätzliche Ventilatoren unterstützt werden, die wahlweise blasend oder saugend arbeiten können. Eine vorteilhafte Ausführungsform kann bspw. einen saugenden Ventilator an einer äußeren Mündung des Luftabfuhrkanals vorsehen, der durch seine Sogwirkung die definierte Luftführung innerhalb des Gehäuses zusätzlich unterstützen kann.The air flow through the air discharge channel can be supported by additional fans, which can operate either blowing or sucking. An advantageous embodiment may provide, for example, a suction fan at an outer mouth of the air discharge channel, which may additionally support the defined air flow within the housing by its suction effect.
Gemäß einer weiteren Ausführungsvariante der vorliegenden Erfindung können innerhalb des Gehäuses nahe der Ein- und/oder Ausgangsöffnungen für die zu trocknenden Gegenstände Blasdüsen mit einer zum Luftabfuhrkanal orientierten Ausströmungsrichtung angeordnet sein. Diese Blasdüsen können bspw. nach schräg oben gerichtet zu beiden Seiten des Transportbandes angeordnet sein. Vorzugsweise sind die Blasdüsen in Nähe bzw. unterhalb des Luftabfuhrkanals angeordnet, so dass durch den Luftaustritt aus diesen Düsen sowie ggf. durch den vom zusätzlichen Ventilator erzeugten Sog die Luftströmung durch das Gehäuse und in Richtung zum Luftabfuhrkanal vorgegeben ist. Idealerweise tritt durch diese Anordnung nur ein sehr geringer Anteil der Trocknungsluft aus den Ein- und Ausgangsöffnungen für die zu trocknenden Gegenstände aus, so dass an diesen Stellen der Aufwand für schalldämpfende Maßnahmen gering gehalten werden kann.According to a further embodiment variant of the present invention, blowing nozzles with an outflow direction oriented toward the air discharge channel can be arranged within the housing near the inlet and / or outlet openings for the objects to be dried. These nozzles may, for example, be arranged obliquely upwards on both sides of the conveyor belt. Preferably, the blast nozzles are arranged in the vicinity of or below the air discharge channel, so that the air flow through the housing and in the direction of the air discharge channel is predetermined by the air outlet from these nozzles and possibly by the suction generated by the additional fan. Ideally, only a very small proportion of the drying air passes through the inlet and outlet openings for the objects to be dried by this arrangement, so that at these points the cost of sound-absorbing measures can be kept low.
Zusätzlich kann das Gehäuse Einrichtungen zur Luft- und/oder Körperschalldämpfung aufweisen, bspw. in Gestalt von Dämmmatten an den Gehäuseinnenflächen. Vorzugsweise sind alle Gehäuseöffnungen abgedichtet, die nicht für die Luftführung erforderlich sind, bspw. Spalte an Klappen oder Deckeln. Die zusätzlichen Dämmmatten können Körperschallschwingungen reduzieren und dafür sorgen, dass die Schallabstrahlung der Gehäuseflächen reduziert ist.In addition, the housing may have facilities for air and / or structure-borne sound damping, for example. In the form of insulating mats to the Housing inner surfaces. Preferably, all housing openings are sealed, which are not required for the air duct, for example. Columns on flaps or covers. The additional insulating mats can reduce structure-borne noise and ensure that the sound radiation of the housing surfaces is reduced.
Eine besonders vorteilhafte Ausgestaltung der erfindungsgemäßen Vorrichtung sieht einen modularen Aufbau mit mehreren nacheinander angeordneten Trocknungsmodulen vor, die miteinander verbunden sind. Die kleinste Einheit wird durch ein einziges Modul gebildet, das eine Eingangsöffnung sowie eine Ausgangsöffnung für zu trocknende Gegenstände wie bspw. Flaschen aufweist. Innerhalb des Gehäuses ist wenigstens ein Düsensatz zum Abblasen der Gegenstände vorhanden. Zudem sind eine Luftzuführung und eine Luftabfuhröffnung notwendig. An dieses eine Modul können sich wahlweise mehrere weitere Module anschließen, die unterschiedliche oder gleiche Düsensätze und ansonsten einen weitgehend gleichen Aufbau aufweisen.A particularly advantageous embodiment of the device according to the invention provides a modular structure with a plurality of successively arranged drying modules, which are interconnected. The smallest unit is formed by a single module having an inlet opening and an outlet opening for objects to be dried, such as bottles. Within the housing there is at least one set of nozzles for blowing off the objects. In addition, an air supply and an air discharge opening are necessary. Optionally, several further modules can be connected to this one module, which have different or the same nozzle sets and otherwise have a largely identical structure.
So kann bspw. in Transportrichtung der Gegenstände ein erstes Trocknungsmodul mit der Eingangsöffnung für die Gegenstände bzw. Flaschen und mit Düsen für eine Trocknung einer Mantelfläche der Gegenstände und/oder eines Flaschenhals ausgestattet sein. Ein sich in Transportrichtung der Gegenstände daran anschließendes zweites Modul kann bspw. mit Düsen für eine Trocknung des Bodens der Gegenstände und/oder eines Flaschenbodens versehen sein. Ein sich in Transportrichtung der Gegenstände anschließendes drittes Modul kann mit der Ausgangsöffnung für die zu trocknenden Gegenstände und mit weiteren Düsen für eine Trocknung der Mantelfläche und/oder des Flaschenhalses versehen sein. Selbstverständlich sind auch Vorrichtungen mit nur zwei Modulen oder auch mit vier oder mehr Modulen möglich, je nach Trocknungsaufwand, der im jeweiligen Anwendungsfall notwendig und sinnvoll ist.Thus, for example, in the transport direction of the articles, a first drying module can be equipped with the inlet opening for the articles or bottles and with nozzles for drying a lateral surface of the articles and / or a bottleneck. An adjoining second module in the direction of transport of the articles may, for example, be provided with nozzles for drying the bottom of the articles and / or a bottle bottom. A third module following in the direction of transport of the articles can be provided with the exit opening for the objects to be dried and with further nozzles for drying the lateral surface and / or the neck of the bottle. Of course, devices with only two modules or with four or more modules are possible, depending on the drying effort, which is necessary and useful in the particular application.
Im Hinblick auf hygienische Anforderungen bei der Getränkeabfüllung und des permanenten Feuchtklimas ist es sinnvoll, wenn die Komponenten der Trocknungsanlage im Wesentlichen aus korrosionsbeständigen Materialen gefertigt sind. Hierfür eignet sich insbesondere Edelstahl. Wahlweise können auch nichtmetallische Komponenten verwendet werden.With regard to hygienic requirements for beverage filling and the permanent humid climate, it makes sense if the components of the drying system are essentially made of corrosion-resistant materials. In particular stainless steel is suitable for this purpose. Optionally, non-metallic components may also be used.
Eine bevorzugte Ausführungsvariante der Erfindung sieht vor, dass wenigstens ein Luftströmungserzeuger durch ein im Gehäuse oder am Gehäuse angeordnetes Gebläse gebildet ist. Ein solches Gebläse kann insbesondere einen elektrischen Antriebsmotor und einen Axial- oder Radialförderer aufweisen, der vorzugsweise mit einem Ansaugluftfilter und/oder mit einem Ansauggeräuschdämpfer versehen ist. Ggf. kann die Leistung des Gebläses variabel einstellbar sein. Um die Verluste durch einen nicht mehr voll durchlässigen Ansaugfilter auszugleichen, kann es sinnvoll sein, den Druckabfall durch die abnehmende Filterdurchlässigkeit mittels eines dafür geeigneten Sensors in der Luftleitung nach dem Gebläse zu erfassen und eine abnehmende Durchlässigkeit durch eine erhöhte Gebläseleistung auszugleichen. Sobald die dadurch erhöhte Gebläseleistung nach länger dauerndem Betrieb einen Maximalwert erreicht hat, kann die Notwendigkeit eines Wechsels oder einer Reinigung des Ansaugfilters angezeigt werden.A preferred embodiment of the invention provides that at least one air flow generator is formed by a blower arranged in the housing or on the housing. Such a fan may in particular comprise an electric drive motor and an axial or radial conveyor, which preferably with a Intake air filter and / or is provided with a Ansauggeräuschdämpfer. Possibly. the power of the blower can be variably adjustable. To compensate for the losses caused by a no longer fully permeable intake filter, it may be useful to detect the pressure drop due to the decreasing filter permeability by means of a suitable sensor in the air line to the fan and compensate for a decreasing permeability through increased fan performance. Once the increased fan power has reached a maximum after prolonged operation, the need to change or clean the suction filter may be indicated.
Wahlweise kann der Luftströmungserzeuger getrennt von der Trocknungsanlage angeordnet und mit dieser über eine Luftleitung verbunden sein. Dies kann bspw. dann von Vorteil sein, wenn auf eine zentrale Luftversorgung für mehrere Module oder für mehrere Trocknungsanlagen zurückgegriffen werden kann. Diese Variante kann jedoch auch Vorteile hinsichtlich einer noch besseren Geräuschreduzierung bieten, da bei den gesamten Geräuschdämmungsmaßnahmen die Schallanteile des Gebläses und dessen Antriebsmotors sowie des Ansauggeräuschs nicht mehr berücksichtigt werden müssen, so dass im Wesentlichen nur noch die Geräuschentwicklung der aus den Trocknungsdüsen austretenden Luft sowie der Luftschall der aus dem Gehäuse geführten Luft zu berücksichtigen ist.Optionally, the air flow generator can be arranged separately from the drying plant and connected to it via an air line. This may, for example, be advantageous if it is possible to resort to a central air supply for several modules or for several drying systems. However, this variant can also offer advantages in terms of even better noise reduction, since in the entire noise reduction measures the sound components of the fan and its drive motor and the intake noise no longer need to be considered, so that essentially only the noise of emerging from the drying nozzles air and the Airborne noise of the air guided out of the housing has to be considered.
Eine weitere Schalldämpfung kann dadurch erreicht werden, dass der Abluftschalldämpfer getrennt vom Gehäuse angeordnet und mit dem Gehäuse über eine Abluftleitung verbunden ist.A further sound attenuation can be achieved in that the exhaust air muffler is arranged separately from the housing and connected to the housing via an exhaust air line.
Die Erfindung umfasst weiterhin ein Verfahren zur Trocknung von Gegenständen, insbesondere von Getränkebehältern wie Flaschen o. dgl., bei dem innerhalb eines weitgehend geschlossenen Gehäuses mittels Luftdüsen die zu trocknenden Gegenstände angeblasen werden, bei dem Trocknungsluft über mindestens eine Luftzuführöffnung zugeführt und die Luft über mindestens eine Abluftöffnung wieder aus dem Gehäuse abgeführt wird. Gemäß der vorliegenden Erfindung wird mittels einer Luftführung im Gehäuse eine definierte Luftabfuhr zur mindestens einen Abluftöffnung erzeugt, wobei die Luft im Wesentlichen an einer Ein- und/oder Ausgangsöffnung für die zu trocknenden Gegenstände vorbei geführt wird. Auf diese Weise wird verhindert, dass Luft aus den Ein- und Ausgängen für die Förderung der Gegenstände durch das Gehäuse unkontrolliert austritt, was alle Schalldämpfungsmaßnahmen aufgrund der unmittelbaren Einflussnahme auf die relevanten Geräuschquellen wesentlich erleichtert. Die Abluft wird gemäß einer bevorzugten Ausgestaltung des erfindungsgemäßen Verfahrens durch wenigstens eine als Schall dämpfender Luftabfuhrkanal ausgebildete Abluftöffnung geleitet.The invention further comprises a method for drying objects, in particular beverage containers such as bottles o. The like., Wherein within a largely closed housing by means of air nozzles, the objects to be dried are blown, supplied in the drying air via at least one air supply and the air over at least an exhaust port is removed again from the housing. According to the present invention, a defined air discharge to the at least one exhaust air opening is generated by means of an air duct in the housing, wherein the air is guided substantially past an inlet and / or outlet opening for the objects to be dried. In this way prevents air from the inlets and outlets for the promotion of the objects through the housing exits uncontrolled, which substantially facilitates all soundproofing measures due to the direct influence on the relevant noise sources. The exhaust air is in accordance with a preferred embodiment of the method according to the invention passed through at least one designed as a sound-absorbing air discharge duct exhaust port.
In weiterer Ausgestaltung des Verfahrens können die innerhalb des Gehäuses nahe der Ein- und/oder Ausgangsöffnungen für die Gegenstände angeordneten Blasdüsen für eine zum Luftabfuhrkanal orientierte Strömungsrichtung der Luft sorgen. Die Luftströmung wird vorzugsweise durch ein im Gehäuse oder am Gehäuse angeordnetes Gebläse erzeugt. Wahlweise kann die Trocknungsluft jedoch auch von außen über eine Luftleitung zugeführt werden.In a further embodiment of the method, the blowing nozzles arranged within the housing near the inlet and / or outlet openings for the articles can provide a flow direction of the air oriented toward the air discharge channel. The air flow is preferably generated by a fan arranged in the housing or on the housing. Optionally, however, the drying air can also be supplied from the outside via an air line.
Eine weitere Ausgestaltung des Verfahrens sieht eine Erfassung eines Förderdrucks oder einer Fördermenge in der Luftförderleitung nach dem Gebläse vor. Auf diese Weise kann insbesondere einem variierenden Förderdruck des Gebläses durch eine Anpassung der Gebläseleistung entgegen gewirkt werden. Der Förderdruck kann bspw. durch eine abnehmende Durchlässigkeit eines zunehmend verstopften Ansaugluftfilters abnehmen. Durch höhere Drehzahl des Gebläsemotors kann die Förderleistung des Gebläses zumindest solange konstant gehalten werden, bis die Maximalleistung des Antriebsmotors erreicht ist.A further embodiment of the method provides for detection of a delivery pressure or a delivery rate in the air delivery line after the blower. In this way, in particular a varying delivery pressure of the blower can be counteracted by an adjustment of the blower output. For example, the delivery pressure may decrease due to decreasing permeability of an increasingly clogged intake air filter. By higher speed of the fan motor, the delivery rate of the fan can be kept constant at least until the maximum power of the drive motor is reached.
