Description

Die Erfindung betrifft eine Einrichtung zum Dosieren eines pastenförmigen Produktes und Vermischen desselben mit einem Lösungsmittel mit einem in einem formstabilen Behälter angeordneten, auswechselbaren, das pastenförmige Produkt aufnehmenden Vorratsgebinde und mit einer unterhalb des Behälters angeordneten, mittels Unterdruck fördernden Dosiervorrichtung, wobei ein durch eine untere Öffnung im Behälter hindurchragender Auslaß des Vorratsgebindes mit einem Produkteinlaß der Dosiervorrichtung kuppelbar ist.The invention relates to a device for dosing a pasty Product and mixing the same with a solvent with an in a dimensionally stable container arranged, replaceable, the pasty Product-holding storage container and with one below the container arranged, conveying by means of negative pressure metering, wherein a through an outlet of the storage container protruding through a lower opening in the container can be coupled to a product inlet of the metering device.

Flüssige bis pastenförmige Waschmittel sind bekannt. Diese Waschmittel sind im allgemeinen auf die Bedürfnisse im Haushalt abgestimmt, was zur Folge hat, daß sie hinreichend flüssig sein sollen und sich problemlos ausgießen und dosieren lassen. Da sie außerdem innerhalb eines größeren Temperaturbereiches lagerstabil sein sollen, kommt man üblicherweise nicht ohne die Anwendung von organischen Lösungsmitteln und/ oder hydrotopen Zusatzstoffen aus. Diese Zusätze sind jedoch waschunaktiv, vergleichsweise aufwendig und beanspruchen zusätzliches Verpackungsvolumen bzw. zusätzliche Transportund Lagerkapazität. Außerdem stört vor allem ein Gehalt an brennbaren Lösungsmitteln, die wegen des vergleichsweise hohen Durchsatzes an Waschmitteln in Wäschereibetrieben zusätzliche Sicherheitsvorkehrungen erfordern. Waschmittelkonzentrate dieser Art sind deshalb für Wäschereien nicht oder nur sehr bedingt brauchbar.Liquid to pasty detergents are known. These detergents are in the generally matched to household needs, which means that they should be sufficiently liquid and pour and dose easily to let. Since they are also within a wide temperature range should be stable in storage, you usually do not come without the use of organic solvents and / or hydrotopic additives. This However, additives are wash-active, comparatively complex and claim additional packaging volume or additional transport and Storage capacity. In addition, a content of flammable is particularly disturbing Solvents due to the comparatively high throughput Detergents in laundry companies take additional safety precautions require. Detergent concentrates of this type are therefore not suitable for laundries or only of limited use.

Es werden daher in Wäschereibetrieben in der Hauptsache pulverförmige Waschmittel eingesetzt. Da insbesondere in großen Betrieben mit weitgehender Automatisierung die genaue Dosierung derartiger Mittel personalaufwendig ist, werden die Mittel meist in vorgelöster Form als Stammlaugen bevorratet und dosiert, d.h. man setzt ein wässriges Konzentrat an, daß dann den einzelnen Verbrauchsstellen zugeführt wird. Die üblicherweise in Wäschereibetrieben verwendeten Waschmittel enthalten jedoch relativ hohe Anteile an Waschalkalien, die nur beschränkt in kaltem Wasser löslich sind und überdies zu Aussalzungseffekten führen. Sie bewirken eine Phasentrennung mit der Folge, daß die organischen Komponenten, insbesondere die nichtionischen Tenside und Seifen, sich abscheiden und aufrahmen. Man muß daher in relativ starker wässriger Verdünnung arbeiten und die Stammlaugen zusätzlich ständig intensiv durchmischen und im Kreislauf führen, um auch in den Zuführungsleitungen zu den Verbrauchsstellen ein Abscheiden einzelner Komponenten zu verhindern. Derartige Verfahren erfordern deshalb hohe Investitionen für geräumige Ansatzbehälter und die damit verbundene Statik für Mischer und Fördereinrichtungen sowie eine ständige Energiezufuhr für das Temperieren und Umpumpen der Stammlaugen. It is therefore mainly powdery in laundry companies Detergent used. Because especially in large companies with extensive Automation the exact dosing of such means is labor-intensive, the funds are usually stored in pre-dissolved form as base liquors and dosed, i.e. one makes an aqueous concentrate, that then the individual Consumption points is fed. Usually in laundries However, detergents used contain relatively high proportions of Washing alkalis, which are only soluble in cold water to a limited extent, and moreover Salting effects lead. They cause phase separation with the consequence that the organic components, especially the nonionic surfactants and soaps, separate and cream. One must therefore be relatively strong watery dilution and the base liquors are also constantly intensive mix and circulate in order to also in the feed lines to prevent the consumer from separating individual components. Such processes therefore require large investments for spacious Mixing container and the associated statics for mixers and Conveyors and a constant supply of energy for tempering and Pumping around the stock liquors.

Ein diesen Anforderungen entsprechendes Waschmittel ist in der EP 0 295 525 A1 beschrieben. Dabei handelt es sich um ein pastöses Waschmittel, das besondere Anforderungen an die Handhabung für das Dosieren und Vermischen mit Wasser als Lösungsmittel stellt. Derartige Waschmittelpasten werden in großen Gebinden transportiert und bevorratet. Es wird vorgeschlagen, diese Vorratsgebinde in einen oberhalb der Dosiervorrichtung angeordneten formstabilen Behälter zu setzen und die Paste nach unten absteigend zu führen. Dabei ist es erforderlich, vor dem Einsetzen des Vorratsgebindes dieses im Bereich seines Auslasses zu öffnen, was dazu führen kann, daß das pastenförmige Produkt beim oder während des Einsetzens des Vorratsgebindes bereits aus dem Vorratsgebinde austritt und in Kontakt mit dem Bedienungspersonal geraten kann. Da derartige Waschmittelpasten jedoch einen Gefahrstoff darstellen können, ist zuverlässig zu vermeiden, daß das pastenförmige Produkt unkontrolliert aus dem Vorratsgebinde austritt.A detergent that meets these requirements is described in EP 0 295 525 A1 described. It is a pasty detergent that special handling requirements for dosing and mixing with water as a solvent. Such detergent pastes are in large containers are transported and stored. It is suggested this Storage containers in one arranged above the dosing device form-stable container and the paste descending down. It is necessary to insert this in the storage container before Open area of his outlet, which can lead to the pasty Product already during or during the insertion of the storage container emerges from the supply container and comes into contact with the operating personnel can guess. However, since such detergent pastes are a hazardous substance can represent reliably avoid the pasty product escapes from the storage container uncontrollably.

Aufgabe der Erfindung ist es deshalb, eine gattungsgemäße Einrichtung so weiter zu entwickeln, daß zuverlässig gewährleistet ist, daß das pastenförmige Produkt aus dem Vorratsgebinde ohne Inkontaktkommen mit dem Bedienungspersonal erst austritt, wenn das Vorratsgebinde an die Dosiervorrichtung angekuppelt ist. The object of the invention is therefore a generic device so to develop further that it is reliably ensured that the pasty Product from the storage container without coming into contact with the Operating personnel only exit when the storage container is attached to the Dosing device is coupled.

Diese Aufgabe wird mit einer Einrichtung der eingangs bezeichneten Art erfindungsgemäß dadurch gelöst, daß der Auslaß des Vorratsgebindes als Auslaßtülle ausgebildet ist und im Bereich des Produkteinlasses eine rohrförmige Tüllenaufnahme vorgesehen ist, die innenseitig mit einem Schneidelement ausgerüstet ist und in die die Auslaßtülle derart einführbar ist, daß das Schneidelement das freie Ende der Auslaßtülle durchsticht.This task is accomplished with a device of the type described in the introduction solved according to the invention in that the outlet of the storage container as Outlet spout is formed and a tubular in the area of the product inlet Grommet holder is provided on the inside with a cutting element is equipped and into which the outlet nozzle can be inserted such that the Cutting element pierces the free end of the outlet spout.

Bei einer so ausgebildeten Einrichtung ist zuverlässig vermieden, daß das pastenförmige Produkt unkontrolliert aus dem Vorratsgebinde austreten kann, bevor das Vorratsgebinde an die Dosiervorrichtung angekuppelt ist. Das Vorratsgebinde wird einfach in den formstabilen Behälter oberhalb der Dosiervorrichtung eingestellt, wodurch automatisch die Auslaßtülle des Vorratsgebindes in die rohrförmige Tüllenaufnahme eindringt und schließlich beim oder nach dem vollständigen Einsetzen die Auslaßtülle vom Schneidelement der Tüllenaufnahme öffnend durchstochen wird, so daß die Öffnung des Vorratsgebindes also erst erfolgt, wenn das Vorratsgebinde bereits vollständig in den Behälter eingesetzt ist.With such a device is reliably avoided that pasty product can escape from the storage container in an uncontrolled manner, before the storage container is coupled to the dosing device. The Storage containers are simply placed in the dimensionally stable container above the dosing device is set, which automatically causes the outlet spout of the storage container in the tubular grommet penetrates and eventually during or after fully insert the outlet spout from the cutting element of the Opening is gripped so that the opening of the Storage container only takes place when the storage container is completely in the container is inserted.

In besonders vorteilhafter Ausgestaltung ist vorgesehen, daß das Schneidelement als Hohlnadel ausgebildet ist, die spitz zulaufend und mit einem besonderen Schliff ausgerüstet sein kann. Auf diese Weise ist ein kontrolliertes Aufschneiden bzw. Aufstechen der Auslaßtülle gewährleistet, was den wesentlichen Vorteil bietet, daß dann, wenn das Vorratsgebinde z.B. bei Störungen vor vollständiger Entleerung entnommen wird, das aufgestochene Auslaßtüllenteil in seine Ausgangsposition zurückfedert und dadurch ein Austreten des pastenförmigen Produktes verhindert wird. In a particularly advantageous embodiment it is provided that the Cutting element is designed as a hollow needle that tapering to a point special grinding can be equipped. This is a controlled one Cutting or piercing the outlet nozzle ensures what the The main advantage is that if the storage container e.g. at Disturbances before complete emptying is removed, the stung Exhaust spout part springs back into its original position and thereby Leakage of the pasty product is prevented.

Vorteilhaft ist vorgesehen, daß die Tüllenaufnahme adapterförmig in den Produkteinlaß der Dosiervorrichtung einsetzbar ist. Die Tüllenaufnahme kann beispielsweise eingeschraubt werden oder nach Art eines Bajonettverschlusses in den Produkteinlaß eingesetzt werden. Auf diese Weise kann die Tüllenaufnahme auf einfache Weise ausgewechselt werden oder entnommen werden, um das Schneidelement zu wechseln bzw. zu reparieren, wenn dies erforderlich ist.It is advantageously provided that the grommet receptacle in the form of an adapter Product inlet of the metering device can be used. The grommet holder can for example screwed in or in the manner of a bayonet catch be used in the product inlet. In this way, the Spout holder can be replaced or removed easily to change or repair the cutting element if this is required.

Ferner ist vorteilhaft vorgesehen, daß zwischen der Tüllenaufnahme und dem Produkteinlaß und/oder der Tüllenaufnahme und der Auslaßtülle ein Dichtelement angeordnet ist, was zuverlässig sicherstellt, daß die mittels Unterdruck fördernde Dosiervorrichtung völlig einwandfrei arbeitet, d.h. keine Umgebungsluft mit in den Produkteinlaß angesaugt werden kann.It is also advantageously provided that between the grommet holder and the Product inlet and / or the spout receptacle and the outlet spout Sealing element is arranged, which reliably ensures that the means Dosing device promoting vacuum works perfectly, i.e. no Ambient air can be sucked into the product inlet.

Außerdem kann vorteilhaft vorgesehen sein, daß die Auslaßtülle freiendseitig einen Anschlagbund aufweist, der den Einführweg der Auslaßtülle in der Tüllenaufnahme begrenzt.In addition, it can advantageously be provided that the outlet nozzle on the free end has a stop collar that the insertion path of the outlet spout in the Spout intake limited.

Weiterhin ist vorteilhaft vorgesehen, daß im Bereich des Produkteinlasses ein beweglicher Verschlußkolben angeordnet ist, der die von der Hohlnadel gebildete Durchtrittsöffnung der Tüllenaufnahme in Verschlußposition dicht verschließt.Furthermore, it is advantageously provided that a in the area of the product inlet movable locking piston is arranged, which of the hollow needle formed passage opening of the spout in the closed position tight closes.

Eine Einrichtung zum Dosieren eines pastenförmigen Produktes und Vermischen desselben mit Wasser weist zunächst eine Dosiervorrichtung auf, die allgemein mit 1 bezeichnet ist. Diese Dosiervorrichtung ist mit einem Gestell ausgestattet, auf welchem ein formstabiler Behälter 2 angeordnet ist, der mit Handhabungsgriffen 3 ausgerüstet sein kann. In diesen Behälter 2 ist ein nur im unteren Bereich dargestelltes flexibles Vorratsgebinde 4 einstellbar. Bodenseitig ist der Behälter 2 mit einer zentralen unteren Öffnung 5 versehen, durch welche eine Auslaßtülle 6 des Vorratsgebindes 4 hindurchführbar ist und in die Dosiervorrichtung 1 hineinragt, was im einzelnen nachfolgend näher erläutert wird. A device for dosing a pasty product and mixing the same with water first has a metering device, the general is denoted by 1. This dosing device is equipped with a frame, on which a dimensionally stable container 2 is arranged, with handling handles 3 can be equipped. In this container 2 is only in flexible storage container 4 shown in the lower area adjustable. base side the container 2 is provided with a central lower opening 5 through which an outlet spout 6 of the storage container 4 can be passed and into the Dosing device 1 protrudes, which is explained in more detail below becomes.

Der grundsätzliche Aufbau der Dosiervorrichtung 1 ist im einzelnen einem Fachmann geläufig, so daß darauf verzichtet wird, mit Ausnahme der für die Erfindung wesentlichen Teile auf diese im einzelnen näher einzugehen. Die Dosiervorrichtung 1 weist zur Aufnahme bzw. zum Ansaugen des pastenförmigen Produktes aus dem Vorratsgebinde 4 einen Produkteinlaß 7 auf sowie einen Wassereinlaß 8. Durch den im Bereich des Produkteinlasses 7 durch die Strömung des eintretenden Wassers entstehenden Unterdruck wird das Wasser mit dem so angesaugten pastenförmigen Produkt vermischt und tritt durch einen Auslaß 9 aus der Dosiervorrichtung 1 im gewünschten Dosierungsverhältnis aus.The basic structure of the metering device 1 is a person skilled in the art common, so that it is omitted, except for that for the invention essential parts of these in more detail. The dosing device 1 points to receiving or sucking the pasty product from the Storage containers 4 a product inlet 7 and a water inlet 8. Through the in the area of the product inlet 7 by the flow of the incoming water The resulting negative pressure becomes the water with the paste-like suction Product mixes and passes through an outlet 9 from the metering device 1 in desired dosage ratio.

Wesentlich für die erfindungsgemäße Gestaltung der Einrichtung ist, daß im Bereich des Produkteinlasses 7 der Dosiervorrichtung 1 eine rohrförmige Tüllenaufnahme 10 angeordnet ist, die innenseitig mit einem Schneidelement 11 ausgerüstet ist. Dabei ist dieses Schneidelement 11 bevorzugt als Hohlnadel ausgebildet.It is essential for the design of the device according to the invention that in the area of the product inlet 7 of the metering device 1 is a tubular spout receptacle 10 is arranged, which is equipped on the inside with a cutting element 11. there this cutting element 11 is preferably designed as a hollow needle.

Die Tüllenaufnahme 10 ist, wie am besten aus Fig. 2 bzw. 4 hervorgeht, bevorzugt adapterförmig in den Produkteinlaß 7 einsetzbar, z.B. mittels eines Schraubgewindes, ein Schraubgewinde ist in Fig. 4 mit 12 bezeichnet. Der Produkteinlaß 7 der Dosiervorrichtung 1 ist, was im einzelnen zeichnerisch nicht dargestellt ist, entsprechend gestaltet, so daß die Tüllenaufnahme 10 auf einfache Weise eingesetzt bzw. ausgetauscht werden kann. The grommet receptacle 10 is preferred, as can best be seen from FIGS. 2 and 4 insertable into the product inlet 7, e.g. by means of a Screw thread, a screw thread is designated in Fig. 4 with 12. The Product inlet 7 of the metering device 1 is what is not drawn in detail is shown, designed accordingly, so that the grommet receptacle 10 on simple Way can be used or exchanged.

Wird ein Vorratsgebinde 4 in den Behälter 2 eingesetzt, so dringt die verschlossene Auslaßtülle 6 des Vorratsgebindes 4 durch die Öffnung 5 des Behälters hindurch in den Bereich des Produkteinlasses 7 und wird im Laufe dieses Vorganges endseitig von dem hohlnadelförmigen Schneidelement 11 durchstochen, d.h. geöffnet. Das Öffnen des Vorratsgebindes 4 erfolgt somit erst dann, wenn das Vorratsgebinde 4 praktisch vollständig in den Behälter 2 eingesetzt ist, so daß ein Inkontaktkommen mit der Waschmittelpaste für das Bedienungspersonal sicher ausgeschlossen ist. Wird das Vorratsgebinde 4 wieder entnommen, federt das von dem hohlnadelförmigen Schneidelement 11 durchstochene Tüllenteil in seine Ausgangsposition zurück und verschließt somit das Vorratsgebinde 4 wieder, so daß Produktreste nicht unkontrolliert aus dem Vorratsgebinde 4 austreten können. Dies ist insbesondere dann von wesentlichem Vorteil, wenn das Vorratsgebinde 4 vor der Entleerung entnommen werden muß, beispielsweise bei Störungen.If a storage container 4 is inserted into the container 2, the penetrates closed outlet nozzle 6 of the storage container 4 through the opening 5 of the Container into the area of the product inlet 7 and is in the course this process at the end of the hollow needle-shaped cutting element 11 punctured, i.e. open. The storage container 4 is thus only opened when the storage container 4 is almost completely in the container 2nd is inserted so that it comes into contact with the detergent paste for the Operating personnel is safely excluded. If the storage container 4 removed again, springs from the hollow needle-shaped cutting element 11 pierced spout part back to its starting position and thus closes the supply container 4 again, so that product residues do not come out of the uncontrolled Storage containers 4 can escape. This is especially true of significant advantage if the storage container 4 removed before emptying must be, for example in the event of faults.

Weitere bevorzugte Einzelheiten der Auslaßtülle 6 und der Tüllenaufnahme 10 sind den Fig. 2 bis 4 zu entnehmen. So sind an der Tüllenaufnahme gemäß Fig. 4 vorzugsweise zwei umlaufende Nuten 13, 14 vorgesehen, in welcher jeweils ein Dichtring 15, 16 oder dgl. eingesetzt werden kann, um zu gewährleisten, daß die Tüllenaufnahme 10 dicht im Bereich des Produkteinlasses 7 (Dichtring 15) und im Verbindungsbereich mit der Auslaßtülle 6 (Dichtung 16) befestigt ist, um eine einwandfreie Funktion der mit Unterdruck arbeitenden Dosiervorrichtung 1 sicherzustellen. Further preferred details of the outlet spout 6 and the spout receptacle 10 are shown in FIGS. 2 to 4. So are on the grommet according to Fig. 4 preferably two circumferential grooves 13, 14 are provided, in each of which a sealing ring 15, 16 or the like can be used to ensure that the grommet holder 10 is tight in the area of the product inlet 7 (sealing ring 15) and is fixed in the connection area with the outlet nozzle 6 (seal 16) perfect functioning of the dosing device 1 working with negative pressure sure.

Die Auslaßtülle 6 weist, wie am besten aus Fig. 3 zu erkennen ist, zum zentrierenden Aufsetzen in bzw. auf die Tüllenaufnahme 10 einen ringförmigen Außenbereich 17 auf, welcher frei endseitig mit einem Anschlagbund 18 versehen ist. Zwischen der eigentlichen Auslaßtülle 6 und dem Außenbereich 17 ist ein Freiraum 19 ausgebildet, in welchen die Tüllenaufnahme 10 beim Zusammenfügen eingreift, wie dies in Fig. 2 dargestellt ist. Dabei liegt die Dichtung 16 dichtend an der Innenseite des ringförmigen Außenbereiches 17 an. Der Anschlagbund 18 dient dazu, die Einführbewegung der Außlaßtülle 6 beim Einsetzen eines Vorratsgebindes 4 in den Behälter 2 nach unten zu begrenzen. Der Anschlagbund 18 liegt dann an einer Gehäusewand 19 der Dosiereinrichtung 1 an.The outlet nozzle 6, as can best be seen from FIG. 3, for centering in or on the grommet receptacle 10 an annular Outside area 17, which has a stop collar 18 on the free end is provided. Between the actual outlet nozzle 6 and the outer region 17th a free space 19 is formed, in which the grommet receptacle 10 Joining engages, as shown in Fig. 2. Here lies the Seal 16 sealingly on the inside of the annular outer region 17. The stop collar 18 serves the insertion movement of the outlet nozzle 6 when Inserting a supply container 4 into the container 2 to limit the bottom.
