Description

Die Erfindung bezieht sich auf Spritzvorrichtungen für Reinigungsnaschinen, insbesondere Flaschenreinigungsmaschinen, mit einem' außerhalb eines die SpritzflUssigkeit zuführenden Spritzkastens angeordneten, absatzweise rotierenden und/oder oszillierenden zylindrischen Düsenkörper, dessen Düsen etwa lotrecht zur Drehachse des DUsenkörpers verlaufen.The invention relates to injection devices for Reinigungsnaschinen, in particular bottle cleaning machines, arranged with an 'outside of the SpritzflUssigkeit supplying spray box intermittently rotating and / or oscillating cylindrical nozzle body, extend the nozzles approximately perpendicular to the axis of rotation of DUsenkörpers.

Insbesondere bei Reinigungsmaschinen für wiederverwendbare Behälter wie Flaschen und dgl. besteht die Aufgabe, die Flaschen so zu reinigen, daß sie unbedenklich erneut mit der betreffenden Flüssigkeit befüllt und in den Verkehr gebracht werden können. Bei Reinigungsmaschinen für die Getränkeindustrie werden die zu reinigenden Flaschen vorzugsweise in an Zellenträgern angeordneten Zellen gehalten und durch die einzelnen Behandlungszonen transportiert. Nach Beendigung des eigentlichen Behandlungsvorganges erfolgt dann eine Aus- und Klarspülung, bei welcher die in den Zellen befindlichen Flaschen mit ihren Mündungen nach unten über Spritzstationen verfahren werden, die quer durch die Maschine verlaufen und für jede Flaschenzeile eine Spritzdüse aufweisen. Es ist dabei bekannt, als Spritzvorrichtungen rotierende Düsenrohre oder -wellen zu benutzen, die von den Flaschenträgern je nach Vorschubgeschwindigkeit der diese bewegenden Ketten absatzweise gedreht werden, so daß der Spritzstrahl in die Flaschenmündung trifft. Insbesondere ist aus einem Prospekt Nr. 27880 der Fa. Ortmann & Herbst, Hamburg, eine Spritzvorrichtung bekannt geworden, bei welcher eine Düsenwelle vorgesehen ist, die kreuzweise angeordnete Düsenbohrungen aufweist, welche mittels eines Drehsternes in Spritzaktion verbringbar sind. Diese Düsenbohrungen sind auf Abstand zueinander angeordnet und außermittig einer zentrisch zur Flaschenmündung weisenden Austrittsöffnung angeordnet. Bei entsprechender Rotation des Antriebssterns spritzt einmal eine in Bewegungsrichtung der Flaschen links zur Flaschenmündung versetzte Düsenbohrung und während des nächsten Spritztaktes die kreuzweise dazu verlaufende und rechts vom Zentrum der Flaschenmündung ausgerichtete Düsenbohrung. Demzufolge sind die Düsenbohrungen ungeachtet ihrer kreuzweisen Anordnung immer seitlich zum Zentrum der darüber hinweggeführten Flaschenmündung ausgerichtet. Insbesondere bei Flaschen unterschiedlicher Größe oder bei einer Verkantung solcher Flaschen oder deren Schrägstellung in den Zellen können die Flaschenmündungen ungeachtet einer unteren zentrischen Zellenführung so weit außerhalb des Bereiches der jeweiligen Spritzbohrung liegen, daß eine exakte Spritzung nicht vollzogen werden kann. Es ist demzufolge nicht auszuschließen, daß die ein oder andere Flasche nicht in der erforderlichen Weise ausgespritzt wird. Dies ist insbesondere in der Getränkeindustrie, bei denen die Flaschen anschließend mit Getränken befüllt werden, außerordentlich gefährlich. Die wiederverwendbaren Flaschen durchfahren während ihrer Behandlung verschiedene Laugeabteilungen und dgl. Es muß deshalb dafür Sorge getragen werden, daß derartige Rückstände nicht in der anschließend zu befüllenden Flasche verbleiben. Es werden deshalb mehrere Spritzabteilungen hintereinander angeordnet, womit ungeachtet der Schräglage einer solchen Flasche mit aller Wahrscheinlichkeit eine Düsenbohrung entsprechend günstig zu der Flaschenmündung ausgerichtet ist und eine entsprechende Ausspritzung der Flasche erfolgt. Dies hat aber wiederum zum Nachteil, daß eine entsprechend hohe Anzahl solcher Spritzstationen vorgesehen sein muß, wodurch sich der Wasserverbrauch insbesondere in der Klarspülzone entsprechend erhöht.Especially in cleaning machines for reusable containers such as bottles and the like. The task is to clean the bottles so that they can be safely refilled with the liquid in question and placed on the market. In cleaning machines for the beverage industry, the bottles to be cleaned are preferably held in cells arranged on cell carriers and transported through the individual treatment zones. After the end of the actual treatment process, a rinse and rinse then takes place, in which the Bottles located in the cells are moved with their mouths downward via spraying stations which run across the machine and have a spray nozzle for each row of bottles. It is known to use rotating nozzle pipes or shafts as spray devices, which are rotated in batches by the bottle carriers depending on the feed speed of the chains moving them, so that the spray jet strikes the bottle mouth. In particular, a spraying device has become known from a brochure no. 27880 from Ortmann & Herbst, Hamburg, in which a nozzle shaft is provided which has crosswise arranged nozzle bores which can be brought into spraying action by means of a rotary star. These nozzle bores are arranged at a distance from one another and are arranged off-center of an outlet opening which points centrally to the bottle mouth. With the corresponding rotation of the drive star, a nozzle bore is sprayed to the left of the bottle mouth in the direction of movement of the bottles and during the next spray cycle the nozzle bore runs crosswise and is aligned to the right of the center of the bottle mouth. As a result, regardless of their crosswise arrangement, the nozzle bores are always aligned laterally to the center of the bottle mouth passed over them. Particularly in the case of bottles of different sizes or in the case of a tilting of such bottles or their inclination in the cells, the bottle mouths, irrespective of a lower central cell guide, can be located so far outside the area of the respective spray hole that an exact spraying cannot be carried out. As a result, it cannot be stopped conclude that one or the other bottle is not sprayed in the required manner. This is extremely dangerous, particularly in the beverage industry, where the bottles are subsequently filled with beverages. The reusable bottles pass through various lye compartments and the like during their treatment. Care must therefore be taken to ensure that such residues do not remain in the bottle to be subsequently filled. A number of spraying departments are therefore arranged one behind the other, which means that regardless of the inclined position of such a bottle, a nozzle bore is most likely aligned with the bottle mouth in a correspondingly favorable manner and the bottle is sprayed out accordingly. However, this in turn has the disadvantage that a correspondingly large number of such spraying stations must be provided, as a result of which the water consumption, in particular in the rinse aid zone, increases accordingly.

Ausgehend von diesem Stand der Technik hat sich die Erfindung nun die Aufgabe gestellt, die vorgenannten Nachteile generell auszuschließen und eine Spritzung zu schaffen, die insbesondere bei kreuzweise auf Abstand zueinander angeordneten drehbaren Düsenbohrungen eine exakte Mittigspritzung auch bei verkanteten oder schräggestellten Flaschen sicherstellt, ohne daß dabei die Anzahl der hintereinander geschalteten Spritzstationen unnötigerweise erhöht und der Wasserverbrauch entsprechend gesteigert werden muß. Darüberhinaus liegt der vorliegenden Erfindung eine weitere Teilaufgabe zugrunde, mit welcher eine Spritzvorrichtung geschaffen werden soll, die einen variablen Spritzeffekt bzw. eine nach vorbestimmten Gesichtspunkten lenkbare Spritzbohrung bzw. eine lenkbare Spritzstrahlführung zuläßt, es also ermöglicht, eine gezielte sphärische Spritzung einzusetzen, mit welcher von Spritzstation zu Spritzstation ganz bestimmte Bereiche eines solchen Flaschenhohlraumes bestrichen werden können und dennoch grundsätzlich auch bei einem solchen Vorgang eine Mittenspritzung gewährleistet ist.Starting from this prior art, the invention has now set itself the task of generally eliminating the aforementioned disadvantages and creating a spray that ensures an exact center spray even with tilted or inclined bottles, especially with rotatable nozzle bores arranged at a distance from one another, without this the number of spray stations connected in series unnecessarily increased and the water consumption increased accordingly. In addition, the present invention is based on a further sub-task with which a spraying device To be created, which allows a variable spray effect or a steerable spray hole or a steerable spray jet guidance, so it is possible to use a targeted spherical spray, with which certain areas of such a bottle cavity can be coated from spray station to spray station and still In principle, a center injection is also guaranteed in such a process.

Die Erfindung löst die Aufgabe bei einer Vorrichtung der eingangs genannten Art dadurch, daß für je eine Spritzstellung zwei oder mehrere Düsen nebeneinander und zusätzlich zu diesen mindestens zwei kreuzweise verlaufende Düsen vorgesehen sind, welche bei ihrer Drehbewegung derart verschiebbar gelagert sind, daß die jeweils in Spritzaktion befindliche Düsenöffnung in beliebiger Position zu einer darüber vorbeigeführten Gefäßmündung verfahrbar ist.The invention solves the problem with a device of the type mentioned in that two or more nozzles are provided next to one another for each spray position and in addition to these at least two cross-shaped nozzles, which are displaceably mounted during their rotational movement such that they are each in spraying action located nozzle opening can be moved in any position to a vessel mouth passed over it.

In selbstständiger Ausgestaltung der Erfindung wird bei Spritzvorrichtungen für Flaschenreinigungsmaschinen, bei denen die Flaschen kontinuierlich und/oder diskontinuierlich vorbeigeführt werden, vorgeschlagen, daß die Düsenöffnung bzw. der daraus austretende Spritzstrahl während des Spritztaktes in an sich bekannter Weise zu der darüber geführten Flasche mitführbar und relativ zu dieser Bewegung mindestens teilweise durch Achsialverschiebung des Düsenkörpers durch den Behälterhohlraum im Sinne einer räumlichen Spritzstrahlkurve lenkbar ist.In an independent embodiment of the invention, it is proposed in spraying devices for bottle cleaning machines in which the bottles are passed continuously and / or discontinuously that the nozzle opening or the spray jet emerging therefrom can be carried along in a manner known per se and relatively to the bottle carried over it during the spray cycle is at least partially steerable to this movement by axial displacement of the nozzle body through the container cavity in the sense of a spatial spray jet curve.

Ferner gehört es zur Erfindung, daß bei mehreren hintereinander geschalteten Spritzvorrichtungen die Spritzbahnkurven entgegengesetzt verlaufen, derart, daß bei einem ersten Spritztakt mindestens eine Gefäßteilhälfte und bei dem nachfolgenden zweiten Spritztakt die verbleibende Gefäßteilhälfte durch die Spritzstrahlbahnkurve bestrichen und mindestens einmal bei diesem Bahnverlauf eine Mittigspritzung zur Gefäßmündung durch Achsialverschiebung des rotierenden Düsenkörpers vollzogen wird.It is also part of the invention that in several spray devices connected in series, the spray path curves run in opposite directions, such that at least one half of the vessel part is smeared by the first spray cycle and the remaining half of the vessel part is smeared by the spray jet path curve in the subsequent second spray cycle, and at least once in this course a middle spray to the vessel mouth is accomplished by axial displacement of the rotating nozzle body.

Dabei hat es sich als zweckmäßig erwiesen, daß der DUsenkUrper vorzugsweise vier DUsenbohrungen In kreuzweise versetzter Anordnung aufweist, von denen von Spritztakt zu Spritztakt die DUsenbohrungen I, II, III und IV und daran anschließend wieder die DUsenbohrung I usw. in Spritzaktion verbringbar sind.It has proven to be expedient that the nozzle body preferably has four nozzle bores in a crosswise offset arrangement, of which the nozzle bores I, II, III and IV and then the nozzle bore I etc. can be brought into spraying action from spray cycle to spray cycle.

Mit der vorliegenden Erfindung ist es erstmalig möglich, eine beliebige und nach vorbestimmbaren Gesichtspunkten ausgerichtete räumliche Spritzung vorzusehen, mit welcher sichergestellt ist, daß ungeachtet der Lage von Flaschen in ihren Zellen eine exakte Mittenspritzung gegeben ist. Es kann je nach Anzahl der hintereinander angeordneten Spritzstationen zielgerichtet eine Mittenspritzung verbunden mit einer Teilraumspritzung und in der nachfolgenden Spritzstation eine Mittenspritzung mit Bestreichen des verbleibenden Flaschenhohlraumes vollzogen werden. Es hängt dabei lediglich von der Ausbildung der die Achsialverschiebung vornehmenden Verstelleinrichtung, beispielsweise einer Kurvenscheibe oder dgl. ab. Die Variationsmöglichkeiten sind zielgerichtet programmierbar. Hinzu kommt, daß durch die Anordnung von vier Düsen pro Spritzeinheit und deren ständige hintereinanderfolgende Beaufschlagung die Verstopfungsgefahr praktisch ausgeschlossen ist, also eine vierfach vergrößerte Sicherheit gegeben ist. Ungeachtet dessen werden bei Rotation derartiger Düsenbohrungen die gegebenenfalls mitgerissenen Partikel abgerieben und deren ständige Freihaltung sichergestellt.With the present invention, it is possible for the first time to provide any spatial spraying which is oriented according to predeterminable aspects and which ensures that, regardless of the position of bottles in their cells, there is an exact center spraying. Depending on the number of spraying stations arranged one behind the other, a center spraying combined with a partial space spraying can be carried out and in the subsequent spraying station a center spraying with painting of the remaining bottle cavity can be carried out. It only depends on the design of the adjusting device that performs the axial displacement, for example a cam disk or the like. The possible variations are programmable. Added to this is the fact that the arrangement of four nozzles per injection unit and their constant application in succession practically preclude the risk of constipation, so there is a fourfold increase in safety. Irrespective of this, any entrained particles are rubbed off during rotation of such nozzle bores and their constant freedom is ensured.

Weitere Merkmale der Erfindung ergehen aus den noch verbleibenden Unteransprüchen.Further features of the invention emerge from the remaining subclaims.

Im nachfolgenden wird die Erfindung anhand eines in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert.The invention is explained in more detail below with reference to an embodiment shown in the drawing.

  • 3 the sprayer in side view,
  • 4 the assignment of the containers to be cleaned,
  • Fig. 5 variants of the spray jet movement direction and
  • Fig. 6 shows the coating areas with variable spraying.

Gemäß dem in der Zeichnung dargestellten Ausführungsbeispiel besteht die Spritzvorrichtung aus einem vorzugsweise rechteckig ausgebildeten Spritzkasten 1, der quer zur Bewegungsrichtung 2 der Flaschen 3 in einer nicht weiter dargestellten Reinigungsmaschine angeordnet ist. Mit diesem Spritzkasten 1 sind Lagerböcke 4 verschraubt, die zur eigentlichen Aufnahme des Düsenkörpers 5 dienen, der zweckmäßig, wie das AusfUhrungsbeispiel zeigt, als durchgehendes Rohr bzw. als durchgehende Welle ausgebildet ist. Wie aus Fig. 1 und 2 ersichtlich, weist die Düsenwelle 5 auf Abstand nebeneinander befindliche DUsenbohrungen I und III sowie zu diesen Bohrungen um 90° versetzte weitere DUsenbohrungen II und IV auf. Die DUsenwelle ist gemäß der in Fig. 1 dargestellten Ausführung in den Lagerböcken 4 gelagert, die ihrerseits eine untere ZufUhröffnung 6 für die Spritzflüssig- ; keit aufweisen und im Austrittsbereich 7 des Spritzstrahls so ausgebildet sind, daß dieser bei Drehung der Düsenwelle einen bestimmten Winkelbereich bestreichen kann, d, h, in Fortbewegungsrichtung 2 der Flaschen 3 mit diesen bewegt werden kann, obwohl der eigentliche Spritzkasten 1 ortsfest angeordnet ist. Die Spritzflüssigkeit tritt dabei durch eine Bohrung 8 des Spritzkastens in den Bereich der ZufUhröffnung 6 des Lagerbocks 4 ein und von hier aus als zielgerichteter Spritzstrahl durch eine darüber befindliche Düsenbohrung I bis IV nach außen. Die Spritzflüssigkeit selbst wird dem Spritzkasten 1 seitlich oder an geeigneter Stelle unter Druck zugeführt, so daß dieser ständig mit Flüssigkeit beaufschlagt ist.According to the exemplary embodiment shown in the drawing, the spray device consists of a preferably rectangular spray box 1, which is transverse to the direction of movement 2 the bottle 3 is arranged in a cleaning machine, not shown. With this spray box 1 bearing blocks 4 are screwed, which serve to actually accommodate the nozzle body 5, which is expediently designed, as the exemplary embodiment shows, as a continuous tube or as a continuous shaft. As can be seen from FIGS. 1 and 2, the nozzle shaft 5 has spaced apart nozzle holes I and III and further nozzle holes II and IV offset from these holes by 90 °. According to the embodiment shown in FIG. 1, the nozzle shaft is supported in the bearing blocks 4, which in turn have a lower feed opening 6 for the spray liquid ; have speed and are formed in the exit region 7 of the spray jet so that it can cover a certain angular range when the nozzle shaft rotates, i.e., in the direction of travel 2 of the bottles 3 can be moved with them, although the actual spray box 1 is arranged in a stationary manner. The spray liquid enters through a bore 8 of the spray box into the area of the feed opening 6 of the bearing block 4 and from here as a targeted spray jet through a nozzle bore I to IV located above it to the outside. The spray liquid itself is supplied to the spray box 1 laterally or at a suitable point under pressure, so that liquid is constantly applied to it.

Durch die Drehung des Düsenkörpers bzw. der Düsenwelle 5 gelangt der Spritzstrahl nur dann nach außen, wenn dieser den oberen Austrittsbereich 7 des Lagerbocks 4 erreicht. In diesem Moment befindet sich die Flasche 3 beispielsweise auf der in Zeichnungsebene linken Seite des in Fig. 1 im Querschnitt dargestellten Spritzkastens 1. Die Flasche wandert dann weiter zur rechten Seite dieses Spritzkastens, wobei durch nicht dargestellte Flaschenkörbe auch eine Drehung der Düsenwelle 5 bewirkt wird, so daß der Spritzstrahl sich ständig mit der Flasche 3 mitbewegt und diese aus unterschiedlichen Winkelstellungen trifft. Sobald beispielsweise die Düsenbohrung I ihren Spritztakt beendet hat, tritt bei der nachfolgenden Flaschenreihe die um 900 versetzte Düsenbohrung II in Aktion, die aber aufgrund des Bohrungsdurchmessers und des zwischen beiden Bohrungen verbleibenden Materials nicht mittig zur darübergeführten Flaschenmündung zentriert ist. Um nun auch diese Bohrung exakt mittig zur Flaschenmündung während des Spritztaktes zu verfahren,erfolgt gleichzeitig zur Drehbewegung der Düsenwelle 5 auch deren geringfügige Achsialverschiebung, mit welcher eine exakte Mittenspritzung gewährleistet ist. Diese Achsialverschiebung der Düsenwelle 5 wird durch nicht weiter dargestellte Verstelleinrichtungen bewirkt, die beispielsweise am Ende einer solchen Düsenwelle angeordnet und als Kurvensteuerscheibe oder dgl. ausgebildet sein könnte. Je nach Ausbildung dieser Verstelleinrichtung kann nun eine beliebige Verfahrweise des Spritzstrahles durch die darüber befindliche Flasche erzielt werden. Ein solches Beispiel ergeht aus den Fig. 5 und 6, in denen dargestellt ist, daß der Spritzstrahl gemäß der in Fig. 5 strichpunktiert gezeichneten Linie diagonal durch die Flasche 3 verfahren werden kann. Bei Anordnung mehrerer Spritzstationen hintereinander kann der nächstfolgende Spritzstrahl die entgegengesetzte Richtung durchfahren, wodurch eine beliebige Flächenwirkung eines solchen Spritzstrahles innerhalb eines Flaschenhohlraumes erzielt werden kann. Ungeachtet dieser mit Fig. 5 und 6 angedeuteten Flächenspritzung kann bei entsprechender Ausbildung der die Düsenwelle 5 bewegenden Verstelleinrichtung eine praktisch räumliche Spritzung erreicht werden, die durch überlagerung der Drehbewegung und Achsialverschiebung der Düsenwelle 3 erfolgt. Eine derartige räumliche Spritzung kann durch entsprechende Neigung der Düsenbohrungen zueinander oder in gleicher Richtung schräg zur Drehachse weiter verfeinert werden.Due to the rotation of the nozzle body or the nozzle shaft 5, the spray jet only reaches the outside when it reaches the upper outlet region 7 of the bearing block 4. At this moment the bottle 3 is, for example, on the left in the plane of the drawing of the spray box 1 shown in cross section in FIG. 1. The bottle then moves further to the right side of this spray box, whereby a rotation of the nozzle shaft 5 is also effected by bottle baskets, not shown, so that the spray jet moves continuously with the bottle 3 and hits it from different angular positions. For example, once the nozzle bore I has finished its spraying stroke, the 90 0 offset nozzle bore II occurs in the subsequent row of bottles in action, but which is not centered due to the bore diameter and the remaining between the two bores material centrally of the guided over the bottle mouth. In order to move this hole exactly in the middle of the bottle mouth during the injection cycle, the nozzle shaft 5 is rotated at the same time as its slight axial displacement, with which an exact center injection is ensured. This axial displacement of the nozzle shaft 5 is brought about by adjusting devices (not shown further) which, for example, could be arranged at the end of such a nozzle shaft and could be designed as a cam control disk or the like. Depending on the design of this adjustment device, any method of spray jet operation can now be achieved through the bottle located above it. An example of this is shown in FIGS. 5 and 6, in which it is shown that the spray jet can be moved diagonally through the bottle 3 in accordance with the line drawn in broken lines in FIG. 5. If several spray stations are arranged one behind the other, the next spray jet can do the opposite Drive through direction, whereby any surface effect of such a spray jet can be achieved within a bottle cavity. Regardless of this surface spraying indicated with FIGS. 5 and 6, with a suitable design of the adjusting device moving the nozzle shaft 5, a practically spatial spraying can be achieved, which takes place by superimposing the rotary movement and axial displacement of the nozzle shaft 3. Such a spatial spraying can be further refined by a corresponding inclination of the nozzle bores to one another or in the same direction at an angle to the axis of rotation.

Die Verstelleinrichtung ist so ausgebildet, daß zunächst gemäß dem Ausführungsbeipiel in Fig. 2 die Düsenbohrung I, im Anschluß daran die Düsenbohrung II, dann die Düsenbohrung III und abschließend die Düsenbohrung IV in Spritzfunktion versetzt wird. Sobald ein solcher Spritzzyklus durch entsprechende Drehung der Düsenwelle 5 abgeschlossen ist, tritt die Düsenbohrung I wieder in Aktion bis hin zur Düsenbohrung IV. Auf diese Weise wird eine exakte Ausspritzung der über dem Spritzkasten 1 hinweggeführten Flaschen 3 erzielt, wobei es nebensächlich ist, in welcher Stellung bzw. Lage sich die betreffenden Flaschen in ihren Z.ellen befinden. Es ist grundsätzlich immer eine Mittenspritzung über einen vorbestimmbaren Winkelbereich gewährleistet.The adjustment device is designed so that first the nozzle bore I, according to the exemplary embodiment in FIG. 2, then the nozzle bore II, then the nozzle bore III and finally the nozzle bore IV are put into a spraying function. As soon as such a spray cycle is completed by a corresponding rotation of the nozzle shaft 5, the nozzle bore I comes into action up to the nozzle bore IV. In this way, an exact ejection of the bottles 3 carried over the spray box 1 is achieved, it being irrelevant which one Position or location of the bottles in question are in their cells. In principle, center injection is always guaranteed over a predeterminable angular range.
