Definitions
- the present invention relates to a device for cleaning boxes for beverage containers.
- the invention will be described with reference to a bottle box cleaner, but it should be noted that the device according to the invention can also be used for cleaning other boxes for beverage containers, for example, boxes for cans and the like.
- a device for washing or cleaning of containers has a second cleaning unit, which is provided for cleaning the interior of the device.
- This second cleaning unit thus at least partially allows self-cleaning of the device.
- For this purpose are along a conveyor line for the containers in a bottom of the device openings arranged, through which a cleaning agent can be removed.
- a return channel for the cleaning agent is also provided in devices known from the prior art. If necessary, after passing through filter devices, the cleaning agent returns to the flow channel via this return channel.
- the present invention is therefore based on the object to improve a self-cleaning process for a device for cleaning boxes. In addition, the removal of contaminated cleaning agents should be improved.
- the inventive device for cleaning boxes for beverage containers has a housing and a bottom, wherein in an interior of the housing at least one is provided from the bottom limited first flow channel along which the boxes are moved by means of a flowing through this flow channel cleaning agent in a conveying direction.
- at least partially separated from the first flow channel return channel is provided in which the cleaning agent is guided in a return direction, wherein the return channel is bounded by the bottom.
- the bottom in the region of the return channel preferably has downwardly directed discharge openings for discharging the cleaning agent.
- a flow channel delimited by the bottom is understood to mean a flow channel that is bounded by the bottom in one direction and, for example, in a second direction by a housing wall or an intermediate wall.
- a total of a channel for the cleaning agent is formed and this detergent flows through this channel and thereby moves the crates with.
- the bottle crates are treated by the cleaning agent, for example prepurified.
- an immersion bath is formed by the flow channel, along which the crates are guided.
- the return duct is also bounded by the floor, for example by the floor and two side walls.
- the inventive arrangement of discharge openings in the return channel it is possible to dissipate impurities also on the return path.
- a filter is often arranged in front of the return channel, but this filter is often chosen so coarse to ensure the necessary flow cross sections that fine dirt particles can get into the return channel. By means of the bottom openings according to the invention, these particles can also be removed from the return channel.
- a return channel can also be provided with recesses and openings preferably a return pipe ie the channel can be designed as a tube.
- a channel is thus understood to mean both a channel open to one side and a closed tube.
- discharge openings would not be provided in the bottom, but these openings would be arranged in the said return pipe.
- This pipeline can in turn lead to branching channels.
- the openings in the return channel are closable or to the openings close to discharge lines and valves.
- the device preferably has a cleaning unit for self-cleaning of the device.
- the present invention is further directed to a device for cleaning boxes for beverage containers, wherein the device comprises a housing and a bottom and wherein in an interior of the housing at least one of the bottom limited first flow channel is provided along which the boxes by means of a be moved by this flow channel flowing detergent in a conveying direction. Furthermore, a return passage, which is at least partially separated from the first flow passage, is provided, in which the cleaning agent is guided along a return direction, wherein the return passage is bounded by the bottom in one direction.

- the spray head it is also possible for the spray head to be arranged stationary relative to the base body, but to permit an exit of a cleaning agent entering it in substantially all directions lying in the circumferential direction. It is possible that on the round body a spherical head is arranged with a plurality of openings and from this head, the cleaning agent passes through these individual openings and thus also exits in all directions with respect to the spray head.
- Such spray heads are also referred to as static spray balls and also allow radiation of the cleaning agent in all radial directions of the cleaning nozzle. This spray ball can additionally be made rotatable.
- the base body is arranged pivotably relative to the device, but in this case the base body is not rotatable in the same way as the spray head.
- Both the rotatably arranged spray head and the spray ball therefore allow the escape of detergent in all radial directions of the cleaning nozzle.
- the said cleaning unit is preferably designed as a separate cleaning unit, that is to say the apparatus has a first cleaning unit for cleaning the boxes themselves and a second cleaning unit for cleaning the interior of the apparatus.
- a bypass could be arranged in a supply line for the cleaning unit and optionally different cleaning agents are sent to the cleaning unit. More specifically, it would be possible for the same cleaning nozzles, which in normal operation clean the boxes, to be cleaned in a special cleaning cycle for the device, for example for the housing inner walls or the bottom of the device.
- the body of the cleaning nozzles is stationary and thus are from the DE 10 2004 058 150 A1 swiveling cleaning nozzles not necessary.

- the rotatable arrangement of the spray head according to the invention relative to the base body allows all-round cleaning, even if the base body is not moved.
- the return direction and the conveying direction are opposite, that is, the bottle crates are moved in the first conveying direction, which is preferably rectilinear and the cleaning agent is returned in the return direction, which runs counter to the conveying direction.
- the discharge openings are arranged in the return channel in itself funnel-shaped downwardly narrowing first bottom depressions. These bottom depressions allow a more efficient removal of the remaining after a cleaning process in the device cleaning agent.
- the depth of the bottom recess increases in the return direction. Preferably, the depth increases steadily, with most preferably the opening at the lowest point of the bottom recess is arranged.
- the openings are arranged such that the cleaning agent can pass through the opening in the return direction. In this way, a particularly simple removal of the liquid is achieved without diverting the flow direction.
- the nozzle is arranged so that the liquid jets generated by the respective nozzle can impinge obliquely on the bottom depression or the walls of this bottom depression.
- the bottom recess thus acts as a collector for remaining after a cleaning process liquid.
- the device has a second flow channel and the return channel is arranged between the first flow channel and the second flow channel.
- the beverage crates are guided in two parallel rows through the immersion bath and the respective recirculating streams are jointly, that is, through a common return channel out.
- more return channels can also be provided on the respective outer sides of the flow channels.
- the device has separation walls for separating the individual channels, that is to say the flow channels and the return channel.
- These partitions are particularly preferred closed walls and fixed to the ground.
- the partitions may in principle also have closable openings.
- the discharge openings according to the invention make it possible to carry out the partitions in their entirety closed, which is not only less expensive, but also increases the reliability, since for example by the operator closing the partitions can not be forgotten.
- the base in the region of the flow channel to drain openings for discharging the cleaning agent.
- these discharge openings are also preferably arranged in funnel-shaped downwardly tapering second bottom depressions, which also act here as collection devices arranged.
- the depth of the second bottom depressions increases in the conveying direction. That is, the depth increases in the opposite direction in contrast to the first bottom recesses in the region of the return channel.
- the second bottom recesses are offset from the first bottom recesses in the flow direction.
- the bottom in an end region of the flow channel has a further discharge opening for discharging the cleaning agent.
- This further discharge opening serves to discharge liquid, which drops when transporting the crates, for example, in higher conveyor paths.
- dirt is removed from a (circulating) filter belt filter.
- This further discharge opening is preferably arranged in a substantially symmetrical base recess, particularly preferably in its center.
- the spray head of the nozzle has two separate outlet openings. Particularly preferably, these two outlet openings are arranged on opposite sides of the spray head. One of the two outlet openings allows a liquid outlet to the side and obliquely downwards and the other outlet opening allows the liquid to escape to the side and obliquely upward.
- the spray head is designed such that the exiting liquid with respect to a longitudinal direction of the nozzle in an angular range between 0 ° and 180 °, preferably between 20 ° and 160 ° can escape.
- the liquid can be directed to the respective adjacent walls in a space surrounding the spray head area.
- the main body of the cleaning nozzle is made of a plastic.
- the spray head of the cleaning nozzle is made of a plastic.

Such a nozzle is cheaper to manufacture than metal nozzles commonly used for such purposes. Also, in such a plastic nozzle, the spray head can be moved more easily with respect to the nozzle body by the cleaning agent flowing therethrough. Preferably, the spray head of the nozzle is mounted relative to the main body of the nozzle by means of a sliding bearing. This also achieves a particularly simple embodiment of the spray nozzle. It is further noted that a plastic nozzle is also relatively insensitive to calcifications. More specifically, it has been shown in elaborate studies that in particular high-precision metal nozzles are less suitable for the present purpose. Conversely, when using the nozzle, it is also not crucial whether the exit of the jet is precisely defined with respect to its direction.
- the sliding bearing allows a certain bearing clearance of the spray head relative to the spray nozzle.
- the flow paths for the cleaning agent in the interior of the spray head are designed such that even particles present in the cleaning fluid can escape through the nozzle. All too fine nozzles would prevent passage of particles present in the cleaning fluid and would therefore be rather unsuitable for the present application.
- the intended bearing clearance allows a smooth running of the spray head relative to the base body and also a smooth running, if, for example, foam passes through this spray head. Any loss of accuracy in the spraying process may be accepted in view of the intended application.

Daneben hat sich gezeigt, dass auch durch die verwendeten Reinigungsdüsen nicht alle Schmutzreste aus der Vorrichtung entfernt werden können. Insbesondere hat sich auch gezeigt, dass beispielsweise Verschmutzungen in Form von feinkörnigem Sand teilweise nur schwer durch die Innenreinigung der Vorrichtung entfernt werden können.In addition, it has been shown that not all dirt residues can be removed from the device by the cleaning nozzles used. In particular, it has also been shown that, for example, soiling in the form of fine-grained sand can sometimes be difficult to remove by the internal cleaning of the device.
Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, einen Selbstreinigungsvorgang für eine Vorrichtung zur Reinigung von Kästen zu verbessern. Daneben soll auch die Abführung von verunreinigten Reinigungsmitteln verbessert werden.The present invention is therefore based on the object to improve a self-cleaning process for a device for cleaning boxes. In addition, the removal of contaminated cleaning agents should be improved.
Dies wird erfindungsgemäß durch die Gegenstände der Ansprüche 1 und 2 erreicht. Vorteilhafte Ausführungsformen und Weiterbildungen sind Gegenstand der Unteransprüche. Es wird darauf hingewiesen, dass die Gegenstände der Ansprüche 1 und 2 sowohl einzeln als auch in Kombination miteinander verwendet werden können und jeweils zur Verwirklichung der der Erfindung zugrundeliegenden Aufgabe dienen.This is inventively achieved by the subject-matter of claims 1 and 2. Advantageous embodiments and further developments are the subject of the dependent claims. It should be noted that the subjects of claims 1 and 2 can be used both individually and in combination with each other and each serve to achieve the object underlying the invention.
Die erfindungsgemäße Vorrichtung zum Reinigung von Kästen für Getränkebehältnisse weist ein Gehäuse und einen Boden auf, wobei in einem Innenraum des Gehäuses wenigstens ein von dem Boden begrenzter erster Strömungskanal vorgesehen ist, entlang dessen die Kästen mit Hilfe eines durch diesen Strömungskanal fließenden Reinigungsmittels in einer Förderrichtung bewegt werden. Daneben ist ein von dem ersten Strömungskanal wenigstens abschnittsweise getrennter Rückführungskanal vorgesehen, in dem das Reinigungsmittel in einer Rückführungsrichtung geführt wird, wobei der Rückführungskanal von dem Boden begrenzt ist. Erfindungsgemäß weist der Boden in dem Bereich des Rückführungskanals bevorzugt nach unten gerichtete Abführungsöffnungen zum Abführen des Reinigungsmittels auf.The inventive device for cleaning boxes for beverage containers has a housing and a bottom, wherein in an interior of the housing at least one is provided from the bottom limited first flow channel along which the boxes are moved by means of a flowing through this flow channel cleaning agent in a conveying direction. In addition, at least partially separated from the first flow channel return channel is provided in which the cleaning agent is guided in a return direction, wherein the return channel is bounded by the bottom. According to the invention, the bottom in the region of the return channel preferably has downwardly directed discharge openings for discharging the cleaning agent.
Unter einem von dem Boden begrenzten Strömungskanal wird ein Strömungskanal verstanden, der von dem Boden in einer Richtung begrenzt wird und beispielsweise in einer zweiten Richtung von einer Gehäusewandung oder einer Zwischenwandung. Damit wird insgesamt ein Kanal für das Reinigungsmittel gebildet und dieses Reinigungsmittel strömt durch diesen Kanal und bewegt dabei auch die Flaschenkästen mit. Innerhalb dieses Strömungskanals werden die Flaschenkästen von dem Reinigungsmittel behandelt, beispielsweise vorgereinigt. Damit wird durch den Strömungskanal ein Tauchbad gebildet, entlang dessen die Flaschenkästen geführt werden.A flow channel delimited by the bottom is understood to mean a flow channel that is bounded by the bottom in one direction and, for example, in a second direction by a housing wall or an intermediate wall. Thus, a total of a channel for the cleaning agent is formed and this detergent flows through this channel and thereby moves the crates with. Within this flow channel, the bottle crates are treated by the cleaning agent, for example prepurified. Thus, an immersion bath is formed by the flow channel, along which the crates are guided.
Der Rückführungskanal ist ebenfalls von dem Boden begrenzt, also beispielsweise durch den Boden und zwei seitliche Wände. Durch die erfindungsgemäße Anordnung von Abführungsöffnungen in den Rückführungskanal ist es möglich, Verunreinigungen auch auf der Rücklaufstrecke abzuführen. Zwar ist oftmals vor dem Rückführungskanal ein Filter angeordnet, doch dieser Filter wird dabei, um die nötigen Strömungsquerschnitte zu gewährleisten, oft so grob gewählt, dass feine Schmutzpartikel in den Rückführungskanal gelangen können. Durch die erfindungsgemäßen Bodenöffnungen können auch diese Partikel aus dem Rückführungskanal entfernt werden.The return duct is also bounded by the floor, for example by the floor and two side walls. The inventive arrangement of discharge openings in the return channel, it is possible to dissipate impurities also on the return path. Although a filter is often arranged in front of the return channel, but this filter is often chosen so coarse to ensure the necessary flow cross sections that fine dirt particles can get into the return channel. By means of the bottom openings according to the invention, these particles can also be removed from the return channel.
Anstelle oder neben einem Rückführungskanal kann auch ein Rückführungsrohr bevorzugt mit Vertiefungen und Öffnungen vorgesehen sein d.h. der Kanal kann als Rohr ausgeführt sein. Unter einem Kanal wird damit sowohl ein nach einer Seite hin offener Kanal als auch ein geschlossenes Rohr verstanden. Weiterhin wäre es auch möglich, den Rückführungskanal in der Art eines Rohres aufzuführen, welches unterhalb des Bodens verläuft. In diesem Falle wären nicht in dem Boden Abführungsöffnungen vorgesehen, sondern diese Öffnungen wären in dem besagten Rückführungsrohr angeordnet. Bevorzugt weist eine derartige unter dem Boden der Vorrichtung verlegte Rohrleitung Vertiefungen auf, in denen die einzelnen insbesondere nach unten weisenden Öffnungen des Rohrs angeordnet sind. Diese Rohrleitung kann wiederum in verzweigende Kanäle münden.Instead of or in addition to a return channel can also be provided with recesses and openings preferably a return pipe ie the channel can be designed as a tube. A channel is thus understood to mean both a channel open to one side and a closed tube. Furthermore, it would also be possible to perform the return channel in the manner of a tube which extends below the bottom. In this case, discharge openings would not be provided in the bottom, but these openings would be arranged in the said return pipe. Preferably, such an under laid down to the bottom of the device wells on which the individual, in particular downwardly facing openings of the tube are arranged. This pipeline can in turn lead to branching channels.
Vorzugsweise sind die Öffnungen in dem Rückführungskanal schließbar bzw. an die Öffnungen schließen sich Abführleitungen und Ventile an. Bevorzugt weist die Vorrichtung eine Reinigungseinheit zur Selbstreinigung der Vorrichtung auf.Preferably, the openings in the return channel are closable or to the openings close to discharge lines and valves. The device preferably has a cleaning unit for self-cleaning of the device.
Die vorliegende Erfindung ist weiterhin auf eine Vorrichtung zum Reinigen von Kästen für Getränkebehältnisse gerichtet, wobei die Vorrichtung ein Gehäuse und einen Boden aufweist und wobei in einem Innenraum des Gehäuses wenigstens ein von dem Boden begrenzter erster Strömungskanal vorgesehen ist, entlang dessen die Kästen mit Hilfe eines durch diesen Strömungskanal fließenden Reinigungsmittels in einer Förderrichtung bewegt werden. Weiterhin ist ein von dem ersten Strömungskanal wenigstens abschnittsweise getrennter Rückführungskanal vorgesehen, in dem das Reinigungsmittel entlang einer Rückführungsrichtung geführt wird, wobei der Rückführungskanal von dem Boden in einer Richtung begrenzt ist. Daneben weist die Vorrichtung eine Reinigungseinheit zur Selbstreinigung der Vorrichtung auf, wobei die Reinigungseinheit eine Vielzahl von Reinigungsdüsen aufweist.The present invention is further directed to a device for cleaning boxes for beverage containers, wherein the device comprises a housing and a bottom and wherein in an interior of the housing at least one of the bottom limited first flow channel is provided along which the boxes by means of a be moved by this flow channel flowing detergent in a conveying direction. Furthermore, a return passage, which is at least partially separated from the first flow passage, is provided, in which the cleaning agent is guided along a return direction, wherein the return passage is bounded by the bottom in one direction. In addition, the device has a cleaning unit for self-cleaning of the device, wherein the cleaning unit has a plurality of cleaning nozzles.
Erfindungsgemäß weist wenigstens eine dieser Reinigungsdüsen einen stationär (gegenüber der Vorrichtung) angeordneten Grundkörper sowie einen drehbar gegenüber diesem Grundkörper angeordneten Sprühkopf auf. Daneben ist es auch möglich, dass der Sprühkopf gegenüber dem Grundkörper stationär angeordnet ist aber einen Austritt eines in diesen eintretenden Reinigungsmittels in im Wesentlichen allen in Umfangsrichtung liegenden Richtungen ermöglicht. Dabei ist es möglich, dass an dem Rundkörper ein kugelförmiger Kopf mit einer Vielzahl von Öffnungen angeordnet ist und aus diesem Kopf das Reinigungsmittel durch diese einzelnen Öffnungen hindurchtritt und damit ebenfalls in alle Richtungen bezüglich des Sprühkopfs austritt. Derartige Sprühköpfe werden auch als statische Sprühkugeln bezeichnet und erlauben ebenfalls eine Abstrahlung des Reinigungsmittels in allen radialen Richtungen der Reinigungsdüse. Auch diese Sprühkugel kann dabei zusätzlich noch drehbar ausgeführt sein.According to the invention, at least one of these cleaning nozzles has a stationary body (arranged opposite the device) and a spray head arranged rotatably relative to this body. In addition, it is also possible for the spray head to be arranged stationary relative to the base body, but to permit an exit of a cleaning agent entering it in substantially all directions lying in the circumferential direction. It is possible that on the round body a spherical head is arranged with a plurality of openings and from this head, the cleaning agent passes through these individual openings and thus also exits in all directions with respect to the spray head. Such spray heads are also referred to as static spray balls and also allow radiation of the cleaning agent in all radial directions of the cleaning nozzle. This spray ball can additionally be made rotatable.
Es wäre denkbar, dass der Grundkörper gegenüber der Vorrichtung schwenkbar angeordnet ist, in diesem Fall ist jedoch der Grundkörper nicht in der gleichen Weise drehbar wie der Sprühkopf.It would be conceivable that the base body is arranged pivotably relative to the device, but in this case the base body is not rotatable in the same way as the spray head.
Sowohl der drehbar angeordnete Sprühkopf als auch die Sprühkugel erlauben daher das Austreten von Reinigungsmittel in allen radialen Richtungen der Reinigungsdüse.Both the rotatably arranged spray head and the spray ball therefore allow the escape of detergent in all radial directions of the cleaning nozzle.
Dabei ist bevorzugt die genannte Reinigungseinheit als separate Reinigungseinheit ausgebiltet, das heißt die Vorrichtung weist eine erste Reinigungseinheit zum Reinigen der Kästen selbst auf und eine zweite Reinigungseinheit zur Innenreinigung der Vorrichtung. Es wäre jedoch auch möglich, nur eine Reinigungseinheit vorzusehen, die sowohl die Kästen als auch die Innenwandungen reinigt. So könnte in einer Zuführungsleitung für die Reinigungseinheit ein Bypass angeordnet sein und wahlweise unterschiedliche Reinigungsmittel auf die Reinigungseinheit gesandt werden. Genauer gesagt wäre es möglich, dass die gleichen Reinigungsdüsen, die im Normalbetrieb die Kästen reinigen, in einem speziellen Reinigungsgang für die Vorrichtung beispielsweise für die Gehäuseinnenwände oder den Boden der Vorrichtung reinigen.In this case, the said cleaning unit is preferably designed as a separate cleaning unit, that is to say the apparatus has a first cleaning unit for cleaning the boxes themselves and a second cleaning unit for cleaning the interior of the apparatus. However, it would also be possible to provide only one cleaning unit that cleans both the boxes and the inner walls. Thus, a bypass could be arranged in a supply line for the cleaning unit and optionally different cleaning agents are sent to the cleaning unit. More specifically, it would be possible for the same cleaning nozzles, which in normal operation clean the boxes, to be cleaned in a special cleaning cycle for the device, for example for the housing inner walls or the bottom of the device.
Damit ist der Grundkörper der Reinigungsdüsen stationär und damit sind die aus der
Die einzelnen Reinigungsdüsen können dabei an den unterschiedlichsten Bereichen im Inneren der Vorrichtung angeordnet sein und insbesondere derart, dass sie auch zu einer Bodenreinigung geeignet sind. Insbesondere auch durch eine Kombination der oben erwähnten erfindungsgemäßen Aspekte ist eine besonders günstige Innenreinigung der erfindungsgemäßen Vorrichtung möglich.The individual cleaning nozzles can be arranged at the most different areas in the interior of the device and in particular such that they are also suitable for a floor cleaning. In particular, by a combination of the above-mentioned aspects of the invention, a particularly favorable internal cleaning of the device according to the invention is possible.
Es ist jedoch auch zusätzlich möglich, dass die Reinigungsdüsen auch in ihrer Gesamtheit schwenkbar oder drehbar angeordnet sind. Vorzugsweise sind zwei unterschiedliche und separate Reinigungseinheiten vorgesehen, wobei eine Reinigungseinheit zum Reinigen der Kästen dient und die andere Reinigungseinheit zur Innenreinigung der gesamten Vorrichtung.However, it is also possible in addition that the cleaning nozzles are arranged pivotally or rotatably in their entirety. Preferably, two different and separate cleaning units are provided, wherein a cleaning unit for cleaning the Boxes and the other cleaning unit for internal cleaning of the entire device.
Die erfindungsgemäße drehbare Anordnung des Sprühkopfs gegenüber dem Grundkörper erlaubt eine Rundumreinigung, selbst wenn der Grundkörper dabei nicht bewegt wird.The rotatable arrangement of the spray head according to the invention relative to the base body allows all-round cleaning, even if the base body is not moved.
Vorzugsweise verlaufen die Rückführungsrichtung und die Förderungsrichtung entgegengesetzt, das heißt die Flaschenkästen werden in der ersten Förderrichtung, die bevorzugt geradlinig verläuft bewegt und das Reinigungsmittel wird in der Rückführungsrichtung, die entgegen der Förderrichtung verläuft, zurückgeführt.Preferably, the return direction and the conveying direction are opposite, that is, the bottle crates are moved in the first conveying direction, which is preferably rectilinear and the cleaning agent is returned in the return direction, which runs counter to the conveying direction.
Bei einer weiteren vorteilhaften Ausführungsform sind die Abführungsöffnungen in dem Rückführungskanal in sich trichterförmig nach unten hin verengenden ersten Bodenvertiefungen angeordnet. Diese Bodenvertiefungen erlauben ein effizienteres Abführen des beispielsweise nach einem Reinigungsvorgang in der Vorrichtung verbleibenden Reinigungsmittels. Bei einer weiteren bevorzugten Ausführungsform nimmt die Tiefe der Bodenvertiefung in der Rückführungsrichtung zu. Vorzugsweise nimmt die Tiefe stetig zu, wobei besonders bevorzugt die Öffnung am tiefsten Punkt der Bodenvertiefung angeordnet ist.In a further advantageous embodiment, the discharge openings are arranged in the return channel in itself funnel-shaped downwardly narrowing first bottom depressions. These bottom depressions allow a more efficient removal of the remaining after a cleaning process in the device cleaning agent. In a further preferred embodiment, the depth of the bottom recess increases in the return direction. Preferably, the depth increases steadily, with most preferably the opening at the lowest point of the bottom recess is arranged.
Bevorzugt sind die Öffnungen derart angeordnet, dass das Reinigungsmittel in der Rückführungsrichtung durch die Öffnung hindurchtreten kann. Auf diese Weise wird ein besonders einfaches Abführen der Flüssigkeit ohne Umlenken der Strömungsrichtung erreicht.Preferably, the openings are arranged such that the cleaning agent can pass through the opening in the return direction. In this way, a particularly simple removal of the liquid is achieved without diverting the flow direction.
Bei einem Zusammenspiel mit der oben erwähnten Düse ist die Düse so angeordnet, dass die von der jeweiligen Düse erzeugten Flüssigkeitsstrahlen schräg auf die Bodenvertiefung bzw. die Wände dieser Bodenvertiefung auftreffen können. Die Bodenvertiefung wirkt damit als Sammeleinrichtung für nach einem Reinigungsvorgang verbleibende Flüssigkeit.In an interaction with the above-mentioned nozzle, the nozzle is arranged so that the liquid jets generated by the respective nozzle can impinge obliquely on the bottom depression or the walls of this bottom depression. The bottom recess thus acts as a collector for remaining after a cleaning process liquid.
Bei einer weiteren bevorzugten Ausführungsform weist die Vorrichtung einen zweiten Strömungskanal auf und der Rückführungskanal ist zwischen dem ersten Strömungskanal und dem zweiten Strömungskanal angeordnet. Bei dieser Ausführungsform werden die Getränkekästen in zwei parallelen Reihen durch das Tauchbad geführt und die jeweils rückführenden Ströme werden gemeinsam das heißt durch einen gemeinsamen Rückführungskanal, geführt. Zusätzlich zu dem gemeinsamen Rückführungskanal, der sich zwischen den beiden Strömungskanälen befindet, können auch an den jeweiligen Außenseiten der Strömungskanäle weitere Rückführungskanäle vorgesehen sein.In a further preferred embodiment, the device has a second flow channel and the return channel is arranged between the first flow channel and the second flow channel. In this embodiment, the beverage crates are guided in two parallel rows through the immersion bath and the respective recirculating streams are jointly, that is, through a common return channel out. In addition to the common return channel, located between the two Flow channels, more return channels can also be provided on the respective outer sides of the flow channels.
Bei einer weiteren vorteilhaften Ausführungsform weist die Vorrichtung Trennungswände zur Trennung der einzelnen Kanäle das heißt der Strömungskanäle und des Rückführungskanals auf. Diese Trennwände sind dabei besonders bevorzugt geschlossene Wände und fest gegenüber dem Boden angeordnet. Die Trennwände können prinzipiell auch verschließbare Öffnungen aufweisen. Die erfindungsgemäßen Abführungsöffnungen erlauben es jedoch, die Trennwände in ihrer Gesamtheit geschlossen auszuführen, was nicht nur kostengünstiger ist, sondern auch die Betriebssicherheit erhöht, da beispielsweise von dem Bediener ein Schließen der Trennwände nicht mehr vergessen werden kann.In a further advantageous embodiment, the device has separation walls for separating the individual channels, that is to say the flow channels and the return channel. These partitions are particularly preferred closed walls and fixed to the ground. The partitions may in principle also have closable openings. However, the discharge openings according to the invention make it possible to carry out the partitions in their entirety closed, which is not only less expensive, but also increases the reliability, since for example by the operator closing the partitions can not be forgotten.
Bei einer weiteren vorteilhaften Ausführungsform weist der Boden in dem Bereich des Strömungskanals Ablassöffnungen zum Abführen des Reinigungsmittels auf. Dabei sind diese Ablassöffnungen ebenfalls bevorzugt in sich trichterförmig nach unten hin verjüngenden zweiten Bodenvertiefungen, die auch hier als Sammeleinrichtungen wirken, angeordnet.In a further advantageous embodiment, the base in the region of the flow channel to drain openings for discharging the cleaning agent. In this case, these discharge openings are also preferably arranged in funnel-shaped downwardly tapering second bottom depressions, which also act here as collection devices arranged.
Dabei nimmt hier die Tiefe der zweiten Bodenvertiefungen in der Förderrichtung zu. Das heißt die Tiefe nimmt im Gegensatz zu den ersten Bodenvertiefungen im Bereich des Rückführungskanals in der jeweils umgekehrten Richtung zu.In this case, the depth of the second bottom depressions increases in the conveying direction. That is, the depth increases in the opposite direction in contrast to the first bottom recesses in the region of the return channel.
Bei einer weiteren bevorzugten Ausführungsform sind die zweiten Bodenvertiefungen gegenüber den ersten Bodenvertiefungen in der Strömungsrichtung versetzt. Durch diese versetzte Anordnung kann die Gesamtstabilität des Bodens erhöht werden und es ist auch möglich, zueinander versetzte Träger für den Boden beispielsweise unterhalb des Bodens anzuordnen.In a further preferred embodiment, the second bottom recesses are offset from the first bottom recesses in the flow direction. By this staggered arrangement, the overall stability of the soil can be increased and it is also possible to arrange mutually offset support for the ground, for example below the ground.
Bei einer weiteren bevorzugten Ausführungsform weist der Boden in einem Endbereich des Strömungskanals eine weitere Ablassöffnung zum Abführen des Reinigungsmittels auf. Diese weitere Ablassöffnung dient zum Abführen von Flüssigkeit, welche beim Transportieren der Getränkekästen, beispielsweise in höhere Förderbahnen, abfällt. Daneben werden Verschmutzungen aus einem (umlaufenden) Siebbandfilter abgezogen. Bevorzugt ist diese weitere Ablassöffnung in einer im Wesentlichen symmetrischen Bodenvertiefung, besonders bevorzugt in deren Zentrum, angeordnet.In a further preferred embodiment, the bottom in an end region of the flow channel has a further discharge opening for discharging the cleaning agent. This further discharge opening serves to discharge liquid, which drops when transporting the crates, for example, in higher conveyor paths. In addition, dirt is removed from a (circulating) filter belt filter. This further discharge opening is preferably arranged in a substantially symmetrical base recess, particularly preferably in its center.
Bei einer weiteren vorteilhaften Ausführungsform weist der Sprühkopf der Düse zwei voneinander getrennte Austrittsöffnungen auf. Besonders bevorzugt sind diese beiden Austrittsöffnungen auf gegenüberliegenden Seiten des Sprühkopfes angeordnet. Eine der beiden Austrittsöffnungen erlaubt dabei einen Flüssigkeitsaustritt zur Seite und schräg nach unten hin und die andere Austrittsöffnung erlaubt einen Austritt der Flüssigkeit zur Seite und schräg nach oben.In a further advantageous embodiment, the spray head of the nozzle has two separate outlet openings. Particularly preferably, these two outlet openings are arranged on opposite sides of the spray head. One of the two outlet openings allows a liquid outlet to the side and obliquely downwards and the other outlet opening allows the liquid to escape to the side and obliquely upward.
Besonders bevorzugt ist der Sprühkopf derart ausgebildet, dass die austretende Flüssigkeit gegenüber einer Längsrichtung der Düse in einem Winkelbereich zwischen 0° und 180°, bevorzugt zwischen 20° und 160° austreten kann. Damit kann flächendeckend in einem den Sprühkopf umgebenden Raum die Flüssigkeit an die jeweils angrenzenden Wände geleitet werden. Durch diese Anordnung des Sprühkopfes kann auf die Schwenkung der Düse in ihrer Gesamtheit verzichtet werden.Particularly preferably, the spray head is designed such that the exiting liquid with respect to a longitudinal direction of the nozzle in an angular range between 0 ° and 180 °, preferably between 20 ° and 160 ° can escape. Thus, the liquid can be directed to the respective adjacent walls in a space surrounding the spray head area. By this arrangement of the spray head can be dispensed with the pivoting of the nozzle in its entirety.
Bevorzugt ist der Grundkörper der Reinigungsdüse aus einem Kunststoff gefertigt. Bei einer weiteren vorteilhaften Ausführungsform ist der Sprühkopf der Reinigungsdüse aus einem Kunststoff gefertigt.Preferably, the main body of the cleaning nozzle is made of a plastic. In a further advantageous embodiment, the spray head of the cleaning nozzle is made of a plastic.
Bei einer weiteren bevorzugten Ausführungsform ist die Reinigungsdüse in ihrer Gesamtheit aus einem Kunststoff gefertigt. Besonders bevorzugt wird als Kunststoff PTFE verwendet. Eine derartige Düse ist in der Herstellung günstiger als üblicherweise für solche Zwecke verwendete Metalldüsen. Auch kann bei einer derartigen Kunststoffdüse leichter der Sprühkopf gegenüber dem Düsenkörper bereits durch das hindurchströmende Reinigungsmittel bewegt werden. Vorzugsweise ist der Sprühkopf der Düse gegenüber dem Grundkörper der Düse mittels eines Gleitlagers gelagert. Auch dadurch wird eine besonders einfache Ausführung der Sprühdüse erreicht. Es wird weiterhin darauf hingewiesen, dass eine Kunststoffdüse auch relativ unempfindlich gegenüber Verkalkungen ist. Genauer gesagt hat sich in aufwendigen Untersuchungen gezeigt, dass insbesondere hochpräzise Metalldüsen für den vorliegenden Zweck weniger geeignet sind. Umgekehrt ist es bei der Verwendung der Düse auch nicht entscheidend, ob der Austritt des Strahls hinsichtlich seiner Richtung genau festgelegt ist.In a further preferred embodiment, the cleaning nozzle is made in its entirety from a plastic. It is particularly preferred to use PTFE as the plastic. Such a nozzle is cheaper to manufacture than metal nozzles commonly used for such purposes. Also, in such a plastic nozzle, the spray head can be moved more easily with respect to the nozzle body by the cleaning agent flowing therethrough. Preferably, the spray head of the nozzle is mounted relative to the main body of the nozzle by means of a sliding bearing. This also achieves a particularly simple embodiment of the spray nozzle. It is further noted that a plastic nozzle is also relatively insensitive to calcifications. More specifically, it has been shown in elaborate studies that in particular high-precision metal nozzles are less suitable for the present purpose. Conversely, when using the nozzle, it is also not crucial whether the exit of the jet is precisely defined with respect to its direction.
Vorzugsweise erlaubt das Gleitlager ein gewisses Lagerspiel des Sprühkopfes gegenüber der Sprühdüse. Daneben sind auch die Strömungspfade für das Reinigungsmittel im Inneren des Sprühkopfes derart ausgeführt, dass auch in der Reinigungsflüssigkeit vorhandene Teilchen durch die Düse austreten können. All zu feine Düsen würden ein Durchtreten von in der Reinigungsflüssigkeit vorhandenen Teilchen verhindern und wären daher für die hier vorliegende Anwendung eher ungeeignet. Durch das vorgesehene Lagerspiel wird eine Leichtgängigkeit des Sprühkopfes gegenüber dem Grundkörper ermöglicht und auch eine Leichtgängigkeit, falls beispielsweise Schaum durch diesen Sprühkopf hindurchtritt. Etwaige Einbußen hinsichtlich der Genauigkeit des Sprühvorgangs können im Hinblick auf die vorgesehene Anwendung in Kauf genommen werden.Preferably, the sliding bearing allows a certain bearing clearance of the spray head relative to the spray nozzle. In addition, the flow paths for the cleaning agent in the interior of the spray head are designed such that even particles present in the cleaning fluid can escape through the nozzle. All too fine nozzles would prevent passage of particles present in the cleaning fluid and would therefore be rather unsuitable for the present application. The intended bearing clearance allows a smooth running of the spray head relative to the base body and also a smooth running, if, for example, foam passes through this spray head. Any loss of accuracy in the spraying process may be accepted in view of the intended application.
Die vorliegende Erfindung ist weiterhin auf einen Boden für eine Vorrichtung der oben beschriebenen Art gerichtet. Dieser Boden weist eine Vielzahl von Abführungsöffnungen und Ablassöffnungen auf, wobei diese Abführungsöffnungen und Ablassöffnungen jeweils in trichterförmigen ersten und zweiten Bodenvertiefungen dieses Bodens angeordnet sind. Erfindungsgemäß sind die ersten Bodenvertiefungen in einer Längsrichtung des Bodens hintereinander angeordnet und auch zweiten Bodenvertiefungen sind in der Längsrichtung des Bodens hintereinander angeordnet. Die Tiefe der ersten Bodenvertiefungen nimmt in der ersten Richtung zu und die Tiefe der zweiten Bodenvertiefungen nimmt ein einer zweiten der ersten Richtung entgegengesetzten Richtung zu. Die erste Richtung ist dabei bevorzugt die oben erwähnte Rückführungsrichtung und die zweite Richtung ist bevorzugt die Förderrichtung.The present invention is further directed to a floor for a device of the type described above. This floor has a plurality of discharge openings and discharge openings, wherein these discharge openings and discharge openings are respectively arranged in funnel-shaped first and second bottom recesses of this floor. According to the invention, the first bottom depressions are arranged one behind the other in a longitudinal direction of the bottom and also second bottom depressions are arranged one behind the other in the longitudinal direction of the bottom. The depth of the first bottom pits increases in the first direction, and the depth of the second bottom pits increases in a direction opposite to the second direction of the first direction. The first direction is preferably the above-mentioned return direction and the second direction is preferably the conveying direction.

In der Sektion I werden die Flaschenkästen 10 durch ein Tauchbad bzw. einen ersten Strömungskanal 8 geführt. Innerhalb dieses ersten Strömungskanals 8 ist ein Reinigungsmittel 18 vorgesehen. Durch die Strömung dieses Reinigungsmittels 18 werden die Flaschenkästen 10 in der durch den Pfeil F gekennzeichneten Richtung gefördert. Dabei ist der Strömungskanal 8 als nach oben offener Trog ausgebildet, der in seiner Breite etwas größer ist als die Breite der zu reinigenden Flaschenkästen. Dieser Trog wird auch durch den Boden 6 der Vorrichtung begrenzt. Dieser Boden weist in
Das Bezugszeichen 42 bezeichnet in seiner Gesamtheit einen Aufwärtswendeförderer, der die Kästen 10 in die zweite Sektion II überführt und dabei gleichzeitig umdreht. Durch dieses Umdrehen können in den Kästen zurückgebliebene Flaschen aus den Kästen herausfallen und in einer Sammeleinrichtung 43 gesammelt werden. Dabei läuft der Aufwärtswendeförderer 42 etwas schneller als die Strömung in dem Strömungskanal 8, sodass die Flaschenkästen gleichzeitig vereinzelt werden. Diese Vereinzelung ist vorteilhaft, damit die einzelnen Kästen 10 durch eine Vielzahl von Spritzdüsen 33 von allen Seiten abgespritzt werden können. Dabei bezeichnet die Sektion II die Hauptreinigung der Flaschenkästen. Die Flaschenkästen werden auf einem Transportband 56 in der Richtung F2 d. h. eine bezüglich F entgegengesetzte Richtung gefördert. Das Bezugszeichen 41 bezieht sich auf einen umlaufenden Siebbandfilter. Dieser Siebbandfilter filtert die schwebenden Schmutzteile aus dem Reinigungsmittel aus. Der in dem Siebbandfilter befindliche Schmutz wird durch ein Gebläse 41 a abgeblasen und gelangt so zur Entsorgung. Schwebender Feinschmutz kann jedoch durch den Siebbandfilter 41 hindurchgelangen und wird, wie unten genauer erläutert, über die Ablassöffnung 26 abgeführt.The
In dem Bereich des Aufwärtswendeförderers 42 werden die Getränkekästen einer intensiven Abspritzung unterzogen. Das hierbei abtropfende Wasser kann ebenfalls durch den Boden 6 nach unten abgeführt werden. Das Bezugszeichen 45 bezieht sich auf einen zweiten Aufwärtswendeförderer der die Kästen von der Sektion II in die Sektion III überführt. Auch hier erfolgt eine intensive Abspritzung der einzelnen Flaschenkästen mithilfe von Spritzdüsen 48. In der oberen Sektion III werden die Flaschenkästen ebenfalls auf einem Transportband 65 wieder in der Richtung F gefördert. In dem Bereich 64 findet dabei eine Laugenentreinigung statt und in dem Bereich 68 eine Nachspritzung insbesondere mit Frischwasser. An diesen Bereich 68 schließt sich eine Abtropfzone 69 an, bevor die Flaschenkästen die Vorrichtung 1 verlassen. Das Bezugszeichen 44 bezieht sich auf eine Nachspritzwanne, die über ein Ventil 44a geleert werden kann.In the area of the up-
Die zusätzlich eingezeichneten Reinigungsdüsen 30 weisen einen unten im Detail beschriebenen stationär angeordneten Grundkörper und einen dem gegenüber drehbaren Sprühkopf auf. Durch diesen drehbaren Sprühkopf wird im Wesentlichen eine 360° Rundum-Reinigung ermöglicht, die zur Reinigung der einzelnen Wände des Gehäuses 4 der Vorrichtung 1 verwendet werden kann. Auch ist es möglich, zur Reinigung die jeweiligen Bodenvertiefungen 16 zu bespritzen. Bei der in

Die jeweils untersten Reinigungsdüsen 30a dienen dabei zur Reinigung des Bodens 6 der Vorrichtung. Die übrigen Reinigungsdüsen dienen auch zur Reinigung der Wände. Dabei sind die Reinigungsdüsen derart ausgeführt, dass sich ein drehbarer Kopf gegenüber einem Grundkörper dreht und damit ein Austritt des Reinigungsmittels im Wesentlichen in alle Richtungen d. h. um 360° möglich ist. Die untersten Düsen 30a sind dabei jeweils nach unten ausgerichtet, d. h. der Kopf der Düsen weist nach unten. Ebenso sind die jeweils obersten Düsen 30b nach unten ausgerichtet, wohingegen die mittleren Düsen 30c teilweise nach oben und teilweise nach unten ausgerichtet sind. Das Bezugszeichen 58 bezieht sich auf Ventilregler, die den zu den Reinigungsdüsen 30 - 30c gelangenden Flüssigkeitsstrom regeln.The respective
Die erfindungsgemäße Reinigungseinheit 50 erlaubt damit ein effizientes Reinigen des vollständigen Innenraums der Kastenreinigungsvorrichtung 1. Die gesamte Reinigungseinheit 50 ist in den Innenraum der in
Die Kästen werden in den beiden Strömungskanälen 8 und 9 jeweils in der Richtung F transportiert und anschließend Reinigungsmittel über einen Rückführungskanal 12 in der Richtung R zurücktransportiert. Daneben können auch weitere Rückführungskanäle an den jeweiligen Außenseiten der beiden Strömungskanäle 8 und 9 vorgesehen sein. Weiterhin ist eine (nicht gezeigte) Wand vorgesehen, die Strömungskanäle 8, 9 jeweils nach außen hin abtrennt.The boxes are transported in the two
Der Boden 6 weist im Bereich des Rückführungskanals 12 eine Vielzahl von ersten Bodenvertiefungen 16 auf. Dabei erhöht sich die Tiefe dieser Bodenvertiefungen 16 jeweils in der Rückführungsrichtung R. Die einzelnen Bodenvertiefungen weisen hier jeweils vier Seitenwände 16a, 16b, 16c und 16d auf. Weiterhin ist die Bodenvertiefung symmetrisch ausgebildet d. h. die beiden Seitenwände 16c und 16d sind zueinander achsensymmetrisch angeordnet. Weiterhin ist in der Seitenwand 16b eine Abführungsöffnung 14 angeordnet. Damit ist die Abführungsöffnung 14 in der Ebene der Seitenwand 16d vorgesehen. Dies ist vorteilhaft, da dadurch ein Austritt des Reinigungsmittels im Wesentlichen in der Richtung R ermöglicht wird und dadurch keine Verwirbelungen auftreten. Die gesamte Bodenvertiefung 16 kann beispielsweise über eine Schweißnaht mit dem Boden 6 verbunden sein.The bottom 6 has a plurality of first bottom recesses 16 in the region of the
Zur Endreinigung der Vorrichtung kann über die einzelnen Abführungsöffnungen 14 das sich im Rückführungskanal 12 befindliche Reinigungsmittel abgeführt werden. Man erkennt auch, dass sich die Seitenfläche 16a in der Rückführungsrichtung R zu der Öffnung 14 hinverjüngt. Auch hierdurch wird ein Abführen des Reinigungsmittels erleichtert. Die Schrägflächen der Seitenwände 16a - 16d lassen sich weiterhin in besonders bequemer Weise von den einzelnen Reinigungsdüsen ausspritzen. Das Bezugszeichen 22 bezieht sich auf weitere Bodenvertiefungen, die in dem Strömungskanal 8 bzw. auch 9 angeordnet sind. Diese Bodenvertiefungen 22 nehmen hinsichtlich ihrer Tiefe in der Richtung F, d. h. in
Das Bezugszeichen 25 bezieht sich auf eine weitere Bodenvertiefung, die in der
Man erkennt, dass in der Längsrichtung L der Vorrichtung zwar die einzelnen übereinander angeordneten Bodenvertiefungen 22 des Strömungskanals 8 auf jeweils gleicher Höhe angeordnet sind, jedoch gegenüber den Bodenvertiefungen 16 des Rückführungskanals in dieser Längsrichtung versetzt sind. Auf diese Weise kann die Stabilität des Bodens 6, der eine erhebliche Menge an Flüssigkeit zur vertragen hat, erhöht werden. Zusätzlich können an den Boden Stege 24 oder Träger vorgesehen sein, die die Gesamtstabilität des Bodens 6 erhöhen.It can be seen that in the longitudinal direction L of the device, although the individual superposed bottom recesses 22 of the
Bei einer weiteren Ausführungsform wäre es auch möglich, dass die Austrittsöffnungen derart gestaltet sind, dass das Reinigungsmittel nicht radial aus diesen austritt sondern schräg und durch diesem schrägen austritt eine Drehung des Sprühkopfes bewirkt wird.In a further embodiment, it would also be possible that the outlet openings are designed such that the cleaning agent does not exit radially from these but obliquely and by this oblique exit a rotation of the spray head is effected.
Die Bezugszeichen 35a, 35b beziehen sich auf Schrägflächen bzw. kegelstumpförmig verlaufende Abschnitte des Sprühkopfes 34. Auch in diesen Schrägflächen 35a, 35b sind Austrittsöffnungen 39a, 39b vorgesehen, bzw. Abschnitte der bereits oben erwähnten Austrittsöffnungen 36. Die Austrittsöffnung 39a ist hier nicht zu sehen, da sie in
Zur Gewichtseinsparung ist die Reinigungsdüse aus einem leichten Material, insbesondere einem Kunststoff, gebildet. Auf diese Weise wird auch ein geringes Trägheitsmoment des Sprühkopfes gegenüber dem Grundkörper erreicht, so dass auch bei geringen Strömungsgeschwindigkeiten und auch in dem Fall, in dem beispielsweise Schaum durch die Düse tritt, eine Drehung des Sprühkopfes bewirkt wird. Daneben weist die Reinigungsdüse 30 in ihrem Inneren grobe Toleranzen auf, um auch auf diese Weise bei evtl. Verunreinigungen eine Leichläufigkeit zu erreichen. Weiterhin ist die erfindungsgemäße Reinigungsdüse aus Kunststoff im Vergleich zu beispielsweise Metalldüsen wesentlich kostengünstiger herzustellen.To save weight, the cleaning nozzle is made of a lightweight material, in particular a plastic. In this way, a low moment of inertia of the spray head with respect to the base body is achieved, so that even at low flow velocities and also in the case in which, for example, foam passes through the nozzle, a rotation of the spray head is effected. In addition, the cleaning
