Flaschen- oder Behälterreinigungsmaschinen sind in unterschiedlichen Ausführungen bekannt und bestehen grundsätzlich aus mehreren, in einem Maschineninnenraum ausgebildeten Behandlungszonen, durch die die Behälter während des normalen Betriebes der Reinigungsmaschine, d.h. während des Behälterreinigungsprozesses mit Hilfe eines maschineninternen Transporteurs in einer Transportrichtung bewegt werden. Der maschineninterne Transporteur besteht in der Regel aus einer Vielzahl von in Transportrichtung aufeinander folgenden Behälter- oder Flaschenkörben, die jeweils beidendig an zwei von Transportketten gebildeten endlos umlaufenden Transportelementen gehalten sind. An einer Behälteraufgabe werden die zu reinigenden Behälter der Reinigungsmaschine bzw. dem maschineninternen Transportsystem zugeführt. An einer Behälterabgabe werden die gereinigten Behälter der Reinigungsmaschine bzw. dem maschineninternen Transportsystem entnommen.Bottle or container cleaning machines are known in various designs and basically consist of a plurality of treatment zones formed in an interior of the machine, through which the containers are kept open during normal operation of the cleaning machine, i. be moved during the container cleaning process using a machine-internal conveyor in a transport direction. The machine-internal conveyor usually consists of a plurality of successive in the transport direction container or bottle baskets, which are held at both ends of two endless conveyor belts formed by transport chains. At a container task, the containers to be cleaned are fed to the cleaning machine or the machine-internal transport system. At a container delivery, the cleaned containers are removed from the cleaning machine or the machine-internal transport system.

Die Behandlungszonen umfassen beispielsweise wenigstens eine als Tauchbad ausgebildete Vorbehandlungszone für ein Vorwärmen der Behälter sowie für ein Vorablösen von Verschmutzungen und Etiketten, bevorzugt wenigstens zwei als Tauchbad ausgeführte Vorbehandlungszonen und wenigstens eine weitere, in Transportrichtung anschließende, als Spritzzone ausgebildete Vorbehandlungszone zum Vorwärmen der Behälter und zum Ablösen von Verschmutzungen und Etiketten unter Verwendung einer Prozessflüssigkeit z.B. in Form von Wasser, daran in Transportrichtung anschließend wenigstens ein als Tauchbad ausgebildete Behandlungszone, vorzugsweise aber wenigstens zwei als Tauchbad ausgebildete Behandlungszonen zum Behandeln der Behälter mit einer Prozessflüssigkeit in Form einer Lauge, daran in Transportrichtung anschließend wenigstens eine Behandlungszone zur Behandlung der Behälter mit einer sogenannten "Nachlauge", d.h. mit einer Lauge niedriger Konzentration u.a. zum Entfernen von an den Behältern haftenden Laugenresten aus den vorausgehenden Tauchbad sowie daran in Transportrichtung anschießend mehrere Behandlungszonen für ein Innen- und Außenabspritzen der Behälter mit einer aus Wasser oder im Wesentlichen aus Wasser bestehenden Prozessflüssigkeit, daran anschließend wenigstens eine Behandlungszone für ein Innen- und Außenabspritzen der Behälter mit Frischwasser und daran anschließend wenigstens eine Behandlungszone zum Trockenen der gereinigten Behälter.The treatment zones comprise, for example, at least one pre-treatment zone designed as an immersion bath for preheating the containers and for pre-soiling contaminants and labels, preferably at least two pre-treatment zones designed as a dip bath and at least one further pre-treatment zone designed as a spray zone for preheating the containers and in the transport direction Removal of contaminants and labels using a process fluid, for example in the form of water, then in the transport direction then at least one formed as an immersion bath treatment zone, but preferably at least two treatment zones formed as an immersion bath for treating the containers with a process liquid in the form of a liquor, then in the transport direction at least one treatment zone for treating the container with a so-called "Nachlauge", ie with an alkali of low concentration, inter alia for removing adhering to the containers lye residues from the previous immersion bath and Thereafter, at least one treatment zone for an internal and external spraying of the container with fresh water and subsequently at least one treatment zone for drying the cleaned container.

Aus hygienischen Gründen bzw. zur Aufrechterhaltung der notwendigen Keimfreiheit ist eine periodische Innenreinigung und/oder -desinfektion der Reinigungsmaschine erforderlich. Um diese Innenreinigung und/oder -desinfektion mit möglichst geringem Zeit- und/oder Arbeitsaufwand durchführen zu können, ist es üblich und bekannt, Flaschen- oder Behälterreinigungsmaschinen mit einem Maschineninnenreinigungs- und/oder -desinfektionssystem auszubilden, mit dem nach Beendigung eines Behälterreinigungsprozesses in einem Maschinenreinigungsmodus die Innenreinigung und/oder -desinfektion zumindest weitestgehend automatisch durchgeführt werden kann. Das Maschineninnenreinigungssystem umfasst u.a. eine Vielzahl von Reinigungs- und Spritzdüsen, über die die im Maschinenreinigungsmodus verwendeten flüssigen Reinigungs- und/oder Desinfektionsmedien beispielsweise als scharfe Strahlen auf alle zu reinigenden und/oder zu desinfizierenden Bereiche des Maschineninnenraumes und der dortigen Funktionselemente ausgebracht werden kann.For hygienic reasons or to maintain the necessary sterility periodic cleaning and / or disinfection of the cleaning machine is required. In order to perform this internal cleaning and / or disinfection with minimal time and / or effort, it is common and known to form bottle or container cleaning machines with a machine cleaning and / or disinfection system, with the after completion of a container cleaning process in a Machine cleaning mode, the interior cleaning and / or disinfection can be performed at least largely automatically. The machine interior cleaning system includes i.a. a plurality of cleaning and spraying nozzles, via which the liquid cleaning and / or disinfecting media used in machine cleaning mode can be applied, for example, as sharp jets to all to be cleaned and / or disinfected areas of the machine interior and the local functional elements.

Die bisherigen Maschineninnenreinigungssysteme erfordern, dass die Prozessflüssigkeiten, die in dem vorausgegangenen Behälterreinigungsprozess verwendet wurden und sich noch in der Flaschen- oder Behälterreinigungsmaschine befinden, vor dem Maschinenreinigungsmodus abgelassen und in der Regel verworfen werden und dass die Innenreinigung und/oder -desinfektion unter Verwendung von Frischwasser ggs. mit reinigenden und/oder desinfizierenden Zusätzen erfolgt, was einen hohen Frischwasserverbrauch und damit verbunden hohe Kosten für die Innenreinigung verursacht, wie z.B. wird im Dokument DE2017942 offenbartThe prior internal machine cleaning systems require that the process liquids used in the previous container cleaning process, which are still in the bottle or container cleaning machine, be drained and generally discarded prior to the machine cleaning mode, and that the interior cleaning and / or disinfecting using fresh water ggs. with cleansing and / or disinfecting additives done what a high fresh water consumption and associated high costs for the internal cleaning caused, such as is in the document DE2017942 disclosed

Aufgabe der Erfindung ist es, ein Verfahren aufzuzeigen, mit dem der Verbrauch an Frischwasser bei der Innenreinigung und/oder -desinfektion und damit auch die Kosten dieser Innenreinigung und/oder -desinfektion wesentlich reduziert werden können. Zur Lösung dieser Aufgabe ist ein Verfahren entsprechend dem Patentanspruch 1 ausgebildet. Eine Flaschen- oder Behälterreinigungsmaschine ist entsprechend dem Patentanspruch 13 ausgeführt.The object of the invention is to provide a method by which the consumption of fresh water in the internal cleaning and / or disinfection and thus the cost of this internal cleaning and / or disinfection can be substantially reduced. To solve this problem, a method according to claim 1 is formed. A bottle or container cleaning machine is designed according to the patent claim 13.

Bei dem erfindungsgemäßen Verfahren wird zumindest eine Prozessflüssigkeit, die bereits in dem den Reinigungsmodus vorausgehenden Behälterreinigungsprozess, während des normalen Reinigungsbetriebes der Reinigungsmaschine verwendet wurde als flüssiges Reinigungsmedium während der Innenreinigung und/oder - desinfektion verwendet. Diese Prozessflüssigkeit wird dabei der betreffenden Behandlungszone oder einem der Behandlungszone zugeordneten Auffangwanne oder einem der Behandlungszone zugeordneten Speicher oder Pufferspeicher entnommen. Grundsätzlich ist es dabei zumindest zweckmäßig zum Reinigen und/oder Desinfizieren einer Behandlungszone die Prozessflüssigkeit einer oder mehrerer Behandlungszonen zu verwenden, die in Transportrichtung des maschineninternen Transportsystems auf die zu reinigende Behandlungszone erfolgen, sodass jede Behandlungszone jeweils mit der bezogen auf die eigene Prozessflüssigkeit niedriger belastete Prozessflüssigkeit einer in Transportrichtung nachfolgenden Behandlungszone gereinigt und/oder desinfiziert wird.In the method according to the invention, at least one process liquid, which was already used in the cleaning process preceding the cleaning mode, during the normal cleaning operation of the cleaning machine, is used as a liquid cleaning medium during the interior cleaning and / or disinfection. This process liquid is taken from the respective treatment zone or a receiving trough associated with the treatment zone or from a storage or buffer store assigned to the treatment zone. In principle, it is at least expedient for cleaning and / or disinfecting a treatment zone to use the process fluid of one or more treatment zones, which take place in the transport direction of the machine-internal transport system to the treatment zone to be cleaned, so that each treatment zone in each case with respect to the own process liquid lower loaded process fluid a downstream in the transport direction treatment zone is cleaned and / or disinfected.

Die Prozessflüssigkeit in Form der Nachlauge wird zur Reinigung, insbesondere Vorreinigung und/oder zur Desinfektion der wenigstens einen Vorbehandlungszone sowie zur Reinigung, insbesondere Vorreinigung und/oder zur Desinfektion des Maschineninnenraumes (Kopfraum) im Bereich der Behälteraufgabe und Behälterabgabe sowie der dortigen Funktionselemente, einschließlich der dortigen Behältertransport- und/oder Einschub- und/oder Ausschubelemente genutzt.The process liquid in the form of the after-liquor is used for cleaning, in particular pre-cleaning and / or disinfection of the at least one pretreatment zone and for cleaning, in particular pre-cleaning and / or disinfection of the machine interior (head space) in the area of container task and container delivery and the functional elements there, including used there container transport and / or insertion and / or Ausschubelemente.
