Description

Verfahren zum Reinigen von Behältern und/oder Behältergebinden und  Method for cleaning containers and / or container containers and
Reinigungsvorrichtung  cleaning device
Die Erfindung betrifft ein Verfahren zum Reinigen von Behältern und/oder Behältergebinden gemäß dem Oberbegriff des Anspruchs 1 und eine Reinigungsvorrichtung zum Durchführen des Verfahrens gemäß Anspruch 8. The invention relates to a method for cleaning containers and / or container containers according to the preamble of claim 1 and a cleaning device for carrying out the method according to claim 8.
Stand der Technik State of the art
Es ist bekannt, in der Getränkeindustrie zur Reinigung die zu reinigenden Behälter, z.B. Flaschen, in mehreren Tauchbädern bestehend aus Lauge oder Wasser zu behandeln, so dass sich Verschmutzungen ablösen. Die Hauptaufgabe liegt hierbei in der Entfernung der Etiketten. Gleichzeitig dienen die Tauchbäder auch zur Innenreinigung der Behälter, wobei dazu zusätzlich Spritzungen mit Lauge und Wasser erfolgt. It is known in the beverage industry to purify the containers to be cleaned, e.g. Treat bottles in several baths consisting of lye or water so that soiling is removed. The main task here is the removal of the labels. At the same time, the immersion baths also serve for the internal cleaning of the containers, with the addition of spraying with lye and water.
Solch eine Reinigung bedingt hohe Medien- und Energieverbräuche, da bei diesen bekannten Reinigungsverfahren das Hauptaugenmerk auf Chemie und Temperatur gerichtet ist, und der Prozess auf die Ablösung von Etiketten , was die größte Herausforderung beim Reinigungspro- zess darstellt, ausgelegt ist. Insbesondere kann dadurch die Innenreinigung überdimensioniert sein, so dass unnötig Energie aufgewendet wird. Such a cleaning requires high media and energy consumption, since in these known cleaning processes the main focus is on chemistry and temperature, and the process is designed for the detachment of labels, which represents the greatest challenge in the cleaning process. In particular, the internal cleaning may be oversized, so that unnecessary energy is expended.
Aufgabe task
Die Aufgabe der Erfindung besteht darin, ein Verfahren zum Reinigen von Behältern und eine entsprechende Reinigungsvorrichtung zum Durchführen des Verfahrens zur Verfügung zu stellen, die eine ökonomische Reinigung ermöglichen. The object of the invention is to provide a method for cleaning containers and a corresponding cleaning device for carrying out the method, which enable economical cleaning.
Lösung solution
Die Aufgabe wird gelöst durch das Verfahren nach Anspruch 1 und die Reinigungsvorrichtung nach Anspruch 8. Bevorzugte Ausführungsformen und Weiterbildungen sind in den Unteransprüchen offenbart. The object is achieved by the method according to claim 1 and the cleaning device according to claim 8. Preferred embodiments and further developments are disclosed in the subclaims.
In einem erfindungsgemäßen Verfahren zum Reinigen von Behältern, wie Glas- oder PET- Flaschen, werden die Behälter mit einem gerichteten Strahl behandelt, wobei der gerichtete Strahl Wasser umfasst, das mit Luftblasen beaufschlagt wird und wobei in dem mit den Luftblasen beaufschlagtem Wasser Ultraschallwellen erzeugt werden, die sich in dem gerichteten Strahl ausbreiten. Da für die Reinigung ein gerichteter Strahl verwendet wird, der mit Luftblasen beaufschlagtes Wasser umfasst, wobei sich in dem Wasser zudem Ultraschaliwellen ausbreiten, ist die Reinigungswirkung des Verfahrens nicht auf chemische Zusätze angewiesen, sondern die Reinigungswirkung beruht auf einen mechanischen Einfluss. In a method according to the invention for cleaning containers, such as glass or PET bottles, the containers are treated with a directional jet, the directed jet comprising water, which is acted upon by air bubbles and wherein ultrasound waves are generated in the water charged with the air bubbles that propagate in the directional beam. Since a directional jet is used for the cleaning, which includes water supplied with bubbles, and in the water also propagate ultrasonic waves, the cleaning effect of the process is not dependent on chemical additives, but the cleaning effect is based on a mechanical influence.
Die Ultraschallwellen breiten sich in Form von Longitudinalwellen aus, wodurch Überdruck- und Unterdruckbereiche in dem Wasser entstehen. Durch die Luftblasen, mit denen das Wasser beaufschlagt ist, wird die Kavitation begünstigt, da die Luftblasen als zusätzliche Kavitationskeime dienen. So kann der nötige Energieeintrag durch den Ultraschall verringert werden, der ohne diese Luftblasen in dem Wasser erforderlich wäre. The ultrasonic waves propagate in the form of longitudinal waves, creating overpressure and negative pressure areas in the water. The air bubbles, which are applied to the water, the cavitation is favored, since the air bubbles serve as additional Kavitationskeime. Thus, the necessary energy input can be reduced by the ultrasound, which would be required without these bubbles in the water.
Durch die Erhöhung des mechanischen Anteils des Reinigungsprozesses mittels Ultraschall können also Kosten für Medienverbrauch und Energie zur Aufheizung großer Medienmengen eingespart werden. By increasing the mechanical proportion of the cleaning process by means of ultrasound, costs for media consumption and energy for heating large quantities of media can thus be saved.
Das erfindungsgemäße Verfahren lässt sich auch zur Reinigung von Behältergebinden, insbesondere Getränkekästen, vorteilhaft einsetzen. Auch dabei ist es von Vorteil, dass der Reinigungsstrahl gezielt auf insbesondere üblicherweise stärker verschmutzte Bereiche derartiger Gebinde gerichtet werden kann, so dass sich bestimmte Bereiche gezielt und energieeffizient reinigen lassen. The inventive method can also be used advantageously for cleaning container containers, in particular beverage crates. Here, too, it is advantageous that the cleaning jet can be directed in a targeted manner to areas of such containers that are usually more heavily soiled, so that certain areas can be cleaned in a targeted and energy-efficient manner.
Das Wasser kann auf eine Temperatur in einem Bereich von Tumgebung«1 T < TSiede erhitzt werden. Durch das warme bzw. heiße Wasser kann der Reinigungseffekt bei stark verschmutzen Behältern erhöht werden. Auch kann das Lösen von Kleber der Etiketten durch das warme bzw. heiße Wasser begünstigt werden. Vorteilhafter Weise wird das Wasser vor dem Beaufschlagen mit den Luftblasen erhitzt, so dass das Beaufschlagen ein definiertes Ergebnis ergibt, wobei eine gewünschte Anzahl und/oder ein gewünschtes Volumen der Luftblasen erreicht wird. Durch eine der Beaufschlagung nachfolgende Erhitzung des Wassers könnte die Anzahl und/oder das Volumen der Luftblasen derart verändert werden, dass sie von jeweiligen gewünschten Werten oder Wertebereichen abweichen. The water can be heated to a temperature in a range of Tambient «1 T <T de. The warm or hot water can increase the cleaning effect of heavily contaminated containers. Also, the dissolution of adhesive of the labels can be favored by the hot or hot water. Advantageously, the water is heated prior to the impingement of the air bubbles, so that the application results in a defined result, wherein a desired number and / or a desired volume of the air bubbles is achieved. By subsequent heating of the water, the number and / or the volume of the air bubbles could be changed such that they deviate from respective desired values or value ranges.
Dem Wasser kann mindestens ein Additiv und/oder mindestens ein Reinigungsmittel beigefügt werden. Beispielsweise kann dem Wasser Lauge zugeführt werden, um eine verbesserte Reinigung zu erreichen. At least one additive and / or at least one cleaning agent can be added to the water. For example, water may be added to the water for improved cleaning.
Beim Beaufschlagen des Wassers mit den Luftblasen können Anzahl und/oder Volumen der Luftblasen gesteuert werden. Je kleiner die Luftblasen sind, umso kleinere Strukturen können durch die Kavitation gereinigt werden. Bei einer größeren Anzahl an Luftblasen kann der benö- tigte Energieeintrag durch den Ultraschall verkleinert werden. Im Allgemeinen wird hier die tatsächliche Anzahl Nmess der Luftblasen im Wasser von einem Wunschwert N um einen statistischen Wert ΔΝ abweichen, so dass Nmess = N + ΔΝ. Gleiches gilt für das tatsächliche Volumen mess der Luftblasen, das von einem Wunschwert V im Allgemeinen um einen statistischen Wert AV abweicht, so dass Vmess = V + AV gilt. Durch eine Steuerung der Anzahl und/oder des Volumens der Luftblasen beim Beaufschlagen des Wassers mit den Luftblasen, wird das Ergebnis somit einen Wertebereich überdecken und nicht notwendiger Weise auf jeweils einen festen Wert beschränkt sein. When pressurizing the water with the air bubbles, the number and / or volume of the air bubbles can be controlled. The smaller the air bubbles, the smaller the structures that can be cleaned by cavitation. With a larger number of air bubbles, the required Taken energy input can be reduced by the ultrasound. In general, here the actual number N mess of the air bubbles in the water will deviate from a desired value N by a statistical value ΔΝ such that N mess = N + ΔΝ. The same applies to the actual volume measurement of the air bubbles, which deviates from a desired value V generally by a statistical value AV, so that V mess = V + AV. By controlling the number and / or the volume of the air bubbles when the water is exposed to the air bubbles, the result will thus cover a range of values and will not necessarily be limited to one fixed value each time.
Die Frequenz und/oder Intensität der Ultraschallwellen kann gesteuert werden. Die Auswahl der Frequenz zur Reinigung eines Behälters hängt beispielsweise von der Empfindlichkeit der Bein älteroberf lache ab. Niedrige Frequenzen können verwendet werden, wenn der Behälter vergleichsweise unempfindliche Oberflächen besitzt. Je empfindlicher die Oberflächen sind und/oder wenn auch engere Zwischenräume, wie Rillen oder Spalten, gereinigt werden sollen, desto vorteilhafter ist eine höhere Frequenz. The frequency and / or intensity of the ultrasonic waves can be controlled. The frequency selection for cleaning a container, for example, depends on the sensitivity of the leg surface. Low frequencies can be used if the container has comparatively insensitive surfaces. The more sensitive the surfaces are and / or if narrower spaces, such as grooves or gaps, are to be cleaned, the more advantageous is a higher frequency.
Die Menge des Wassers kann steuerbar sein. So kann die Ausbringstärke des gerichteten Strahls variiert werden. The amount of water can be controllable. Thus, the Ausbringstärke the directional beam can be varied.
Zudem kann eine Ausbringrichtung des gerichteten Strahls steuerbar sein. So ist es möglich, den gerichteten Strahl über einen Kantenbereich des auf einem Behälter angebrachten Etiketts zu bewegen, so dass der Strahl zumindest meistens aus einer seitlichen Richtung auftrifft. Solch ein Auftreffwinkel begünstigt ein Ablösen des Etiketts von dem Behälter, da der Strahl dann während eines Reinigungsprozesses in einem Bereich zwischen Behälteroberfläche und Etikett auftrifft. Auch ist es möglich, den Strahl ins Innere der Behälter zu richten, um so die Innenreinigung durchführen zu können. In addition, a delivery direction of the directional beam can be controlled. Thus, it is possible to move the directional beam over an edge region of the label mounted on a container, so that the beam is at least mostly incident from a lateral direction. Such an angle of incidence promotes detachment of the label from the container since the jet then impacts a region between the container surface and the label during a cleaning process. It is also possible to direct the jet into the interior of the container so as to be able to carry out the internal cleaning.
Eine erfindungsgemäße Reinigungsvorrichtung für Behälter, wie Glas- oder PET-FIaschen, zum Durchführen mindestens eines der Verfahren, wie oben oder weiter unten beschrieben, umfasst eine Kammer mit einer Luftzuführung, einer Wasserzuführung und einer Auslassdüse, wobei in der Auslassdüse eine Ultraschallquelle vorgesehen ist. In die Kammer wird mittels der Wasserzuführung Wasser eingebracht. Dieses Wasser wird dann mit Luftblasen beaufschlagt, die mittels der Luftzuführung ebenfalls in die Kammer eingebracht werden. Das mit Luftblasen beaufschlagte Wasser wird dann durch die Auslassdüse aus der Kammer als gerichteter Strahl ausgebracht, wobei mittels der Ultraschallquelle Ultraschallwellen erzeugt werden, die sich in dem gerichteten Strahl ausbreiten. Der gerichtete Strahl mit den sich darin ausbreitenden Ultraschallwellen kann nach Verlassen der Auslassdüse auf zu reinigende Behälter aufgebracht werden, die beispielsweise ein oder mehrere Etiketten aufweisen.
