Description

Die Erfindung betrifft eine Mischmaschine zum Vermischen einer pulverförmigen Trockensubstanz, insbesondere Trockenmörtel oder trockenes Farbpulver, mit Wasser mit einem insbesondere trichterförmigen Vorratsbehälter für die pulverförmige Trockensubstanz sowie mit einer Förder- und Mischeinrichtung zum Austrag der pulverförmigen Trockensubstanz aus dem Vorratsbehälter unter Zugabe und Vermischen mit Wasser.The invention relates to a mixing machine for mixing a powdery dry substance, in particular dry mortar or dry color powder, with water, in particular with a funnel-shaped storage container for the powdery dry substance, and with a conveying and mixing device for discharging the powdery dry substance from the storage container with addition and mixing with water.

Das besondere Anwendungsgebiet der Erfindung ist eine Mischmaschine zum Herstellen von Mörtel sowie eine Mischmaschine zum Herstellen von Farbe. Bei der Mörtelmischmaschine wird dem Trockenmörtel Wasser hinzugegeben und mit diesem vermischt, so daß der benötigte Naßmörtel entsteht. Bei der Farbmischmaschine wird von trockenem Farbpulver ausgegangen, welchem zur Herstellung der nassen Farbe Wasser zugemischt wird.The particular field of application of the invention is a mixing machine for producing mortar and a mixing machine for producing paint. In the mortar mixing machine, water is added to the dry mortar and mixed with it, so that the required wet mortar is produced. The paint mixing machine starts with dry paint powder, which is mixed with water to produce the wet paint.

Eine Mischmaschine in Form einer Mörtelmischmaschine der eingangs angegebenen Art unter Verwendung eines Kleinsilos von beispielsweise 1,2 Tonnen oder größer wird verwendet, um am jeweiligen Einsatzort den benötigten Naßmörtel herzustellen. Die bekannte Mörtelmischmaschine weist dabei einen trichterförmigen Vorratsbehälter zur Aufnahme des Trockenmörtels auf. An die untere Austragsöffnung des Vorratsbehälters kann dabei eine separate, rohrförmige Förder- und Mischeinrichtung zum Austrag des Trockenmörtels aus dem Vorratsbehälter unter Zugabe und Vermischen mit Wasser angeflanscht werden.A mixing machine in the form of a mortar mixing machine of the type specified at the beginning using a small silo of, for example, 1.2 tons or larger is used to produce the required wet mortar at the respective place of use. The known mortar mixer has a funnel-shaped storage container for receiving the dry mortar. A separate, tubular conveying and mixing device for discharging the dry mortar from the storage container while adding and mixing with water can be flanged to the lower discharge opening of the storage container.

Bei dieser bekannten Mischmaschine ist von Nachteil, daß bei einem leeren Vorratsbehälter ein Weiterarbeiten nur dann möglich ist, wenn er gegen einen vollen Vorratsbehälter ausgetauscht wird. Dies bedeutet aber eine Arbeitsunterbrechung.A disadvantage of this known mixing machine is that, in the case of an empty storage container, it is only possible to continue working if it is exchanged for a full storage container. But this means an interruption of work.

Davon ausgehend liegt der Erfindung die Aufgabe zugrunde, eine Mischmaschine der eingangs angegebenen Art zu schaffen, mit der ein kontinuierliches Arbeiten ohne Arbeitsunterbrechung möglich ist.Proceeding from this, the object of the invention is to create a mixing machine of the type specified at the beginning, with which continuous work is possible without interrupting work.

Als technische Lösung wird mit der Erfindung vorgeschlagen, daß oberhalb des Vorratsbehälters ein Nachfüllbehälter anordenbar ist, wobei die Oberseite des Vorratsbehälters und die Unterseite des Nachfüllbehälters entsprechende Öffnungen aufweisen, die über eine Verbindungsleitung miteinander verbindbar sind.As a technical solution , the invention proposes that a refill container can be arranged above the reservoir, the top of the reservoir and the underside of the refill having corresponding openings which can be connected to one another via a connecting line.

Dies stellt eine technisch einfache Möglichkeit dar, um auf einfache Weise den Vorrat an Trockensubstanz auf beispielsweise über 2 Tonnen zu erweitern, ohne daß der Vorratsbehälter gegen einen neuen ausgetauscht werden muß. Vielmehr ist der Vorratsbehälter direkt auf der Baustelle nachfüllbar, indem auf den Vorratsbehälter der volle Nachfüllbehälter aufgesetzt wird, so daß nach Öffnen der Verbindungsleitung die Trockensubstanz des Nachfüllbehälters in den Vorratsbehälter fließen kann. Nachdem der Nachfüllbehälter so entleert worden und der Vorratsbehälter gefüllt worden ist, kann der leere Nachfüllbehälter wieder entfernt werden. Dadurch ist ein kontinuierliches Arbeiten ohne Arbeitsunterbrechung möglich.This is a technically simple way to easily expand the dry matter supply to, for example, over 2 tons without having to replace the storage container with a new one. Rather, the storage container can be refilled directly at the construction site by placing the full refilling container on the storage container, so that after opening the connecting line, the dry substance of the refilling container can flow into the storage container. After the refill container has been emptied and the storage container has been filled, the empty refill container can be removed again. This makes it possible to work continuously without interrupting work.

In einer ersten Alternative ist der Nachfüllbehälter ein Behälter mit festen Wandungen.In a first alternative, the refill container is a container with fixed walls.

Vorzugsweise ist der Nachfüllbehälter auf das Gestell aufsetzbar ist. Dies stellt eine einfache Möglichkeit dar, um den Nachfüllbehälter auf dem Vorratsbehälter anzuordnen.The refill container can preferably be placed on the frame. This is a simple way to arrange the refill container on the storage container.

Eine weitere Weiterbildung schlägt vor, daß der Nachfüllbehälter eine entsprechende palettenfähige Querschnittsgestalt wie das Gestell aufweist. Dadurch ergeben sich einfache Transportmöglichkeiten.A further development suggests that the refill container has a corresponding cross-sectional shape suitable for pallets, such as the frame. This results in easy transportation options.

Vorzugsweise ist die Verbindungsleitung ein Schlauch oder ein zieharmonikaartiges Rohr. Dies stellt eine technisch einfache Möglichkeit dar, um eine Verbindung zwischen dem Nachfüllbehälter und dem Vorratsbehälter herzustellen, indem nach Öffnen der entsprechenden Öffnungen das Verbindungsrohr entsprechend angeflanscht wird. Dies ermöglicht eine staufreie Übergabe vom Nachfüllbehälter zum Vorratsbehälter.The connecting line is preferably a hose or an accordion-like tube. This represents a technically simple possibility to establish a connection between the refill container and the storage container by flanging the connecting pipe accordingly after opening the corresponding openings. This enables a jam-free transfer from the refill container to the storage container.

Dabei schlägt eine weitere Weiterbildung vor, daß die Verbindungsleitung an der Öffnung des Nachfüllbehälters fest angeordnet und zum Anflanschen auf der Öffnung des Vorratsbehälters nach unten ziehbar ist. Somit ist die Verbindungsleitung dauerhaft am Nachfüllbehälter angeordnet und braucht für die Befüllung des Vorratsbehälters nur nach unten gezogen zu werden.A further development suggests that the connecting line is fixedly arranged at the opening of the refill container and can be pulled downward for flanging on the opening of the storage container. Thus, the connecting line is permanently arranged on the refill container and only needs to be pulled down to fill the storage container.

Alternativ zu dem Nachfüllbehälter mit den festen Wandungen kann der Nachfüllbehälter auch ein flexibler Behälter sein, welcher in ein oberhalb des Vorratsbehälters befestigbares Gestell einhängbar ist. Derartige "Big Bag's" für Schüttgüter werden als Nachfülleinheit bzw. Nachschubeinheit von der Produktionsstätte beispielsweise zu einer Baustelle benutzt. Der Vorteil dieser flexiblen Behälter besteht darin, daß sie nur sehr wenig wiegen, so daß sie im zusammengelegten Zustand nur sehr geringe Rücktransportkosten zur Wiederbefüllung verursachen. Die Nutzungsdauer eines derartigen flexiblen Behälters liegt dabei bei ungefähr 5 Jahren. Der flexible Behälter wird in ein Aufnahmegestell oberhalb der eigentlichen Mischmaschine eingehängt. Bei Bedarf kann dann der Auslaufschlauch des Behälters geöffnet werden, um das Material in den Vorratsbehälter fließen zu lassen.As an alternative to the refill container with the fixed walls, the refill container can also be a flexible container which can be suspended in a frame which can be fastened above the storage container. Such "big bags" for bulk goods are used as refill units or replenishment units from the production site, for example to a construction site. The advantage of these flexible containers is that they weigh very little, so that they only cause very low return costs for refilling when folded. The useful life of such a flexible container is approximately 5 years. The flexible container is suspended in a holder above the actual mixing machine. If necessary, the outlet hose of the container can then be opened to allow the material to flow into the storage container.

Vorzugsweise weist der Nachfüllbehälter einen Auslaufschlauch zum Befestigen auf der Öffnung der Vorratsbehälters auf. Auf eine zusätzliche Verbindungseinrichtung kann somit verzichtet werden.The refill container preferably has an outlet hose for attachment to the opening of the storage container. An additional connecting device can thus be dispensed with.

Eine Weiterbildung hiervon schlägt vor, daß der Auslaufschlauch des Nachfüllbehälters doppelt ausgeführt ist und zum einen in das Innere eines Übergangsstückes ragt und zum anderen über das Übergangsstück außen gestülpt ist. Zur staubfreien und wasserdichten Übergabe aus dem flexiblen Behälter wird vorzugsweise ein Übergangsstück auf die oberseitige Öffnung des Vorratsbehälters gelegt. Der doppelte Auslaufschlauch des Behälters ragt einmal in das Innere dieses Übergangsstücks und zum anderen wird er über das Übergangsstück außen gestülpt. Ein Verrutschen wird mittels einer sogenannten Sackschnalle verhindert.A further development of this suggests that the outlet hose of the refill container is double and protrudes on the one hand into the interior of a transition piece and on the other hand is put over the transition piece on the outside. For the dust-free and watertight transfer from the flexible container, a transition piece is preferably placed on the top opening of the storage container. The double outlet hose of the container protrudes into the interior of this transition piece and, on the other hand, it is placed over the transition piece on the outside. Slipping is prevented by means of a so-called bag buckle.

Das Gestell kann vorzugsweise mittels ausziehbarer Füße der Länge des Behälters angepaßt werden.The frame can preferably be adapted to the length of the container by means of extendable feet.

Eine weitere bevorzugte Weiterbildung schlägt schließlich vor, daß die Maschine ein Gestell mit einem über seine gesamte Höhe gleichmäßig rechteckigen Querschnitt aufweist. Dadurch wird die Mischmaschine palettenfähig sowie hochlagerfähig. Sie ist mit einem Gabelstapler an allen vier Seiten zugänglich und mit einem Handhubwagen zu handhaben. Der Transport der Mischmaschine kann dabei mit allen gängigen Hubwagen, Staplern oder Kranen durchgeführt werden. Durch die eingehaltenen Euro-Paletten-Maße (80 x 120 cm) ist eine optimale Ausnutzung der LKW-Ladeflächen sowie von Hochregallagerflächen gegeben. Für den Transport auf einem LKW oder einem Anhänger sind ausziehbare Füße des Gestells einzuschieben. Dadurch wird eine zusätzliche Transportsicherung, bedingt durch einen niedrigen Schwerpunkt, überflüssig.Another preferred development finally suggests that the machine has a frame with a uniformly rectangular cross section over its entire height. This means that the mixing machine can be used on pallets and in high storage. She is with a forklift accessible on all four sides and can be handled with a hand pallet truck. The mixing machine can be transported with all common lifting trucks, forklifts or cranes. Due to the Euro pallet dimensions (80 x 120 cm), the truck loading areas and high-bay storage areas can be optimally used. Extendable feet of the frame must be pushed in for transport on a truck or a trailer. This eliminates the need for an additional transport lock due to the low center of gravity.

Die Fig. 1 bis 6 zeigen die Grundversion einer Mörtelmischmaschine, während in Fig. 7 und 8 die erfindungsgemäße Erweiterungsform mit einem Nachfüllbehälter in zwei Ausführungsformen dargestellt ist.1 to 6 show the basic version of a mortar mixing machine, while in FIGS. 7 and 8 the extension form according to the invention with a refill container is shown in two embodiments.

Die in den Fig. 1 bis 6 dargestellte Grundversion der Mörtelmischmaschine weist ein quarderförmiges Gestell 1 in Euro-Paletten-Größe (80 x 120 cm) auf und ist stapelbar. Dieses Gestell 1 weist in verschiedene Höhen ausziehbare Füße 2 auf, welche strichpunktiert dargestellt sind. Somit kann jede marktübliche Mörtelpumpe sowie andere Gefäße unterschiedlicher Bauhöhe beschickt werden. Innerhalb des Gestells befindet sich ein trichterförmiger Vorratsbehälter 3, welcher nach unten hin konisch zuläuft, wie insbesondere die Darstellungen in den Fig. 2 bis 4 erkennen lassen. Die beiden Schrägwände weisen dabei einen unterschiedlichen Neigungswinkel auf. Das Nachrutschen des Trockenmörtels ist somit gewährleistet. Außerdem weist der Vorratsbehälter 3 einen Füllstandsmelder auf. Dieser Vorratsbehälter 3 dient gleichzeitig auch als Transportbehälter. Im Bodenbereich dieses Vorratsbehälters 3 ist eine Fördereinrichtung 4 mit einer Förderschnecke 5 angeordnet. Angetrieben wird diese Förderschnecke 5 durch einen Elektromotor 6, welcher sich in Axialrichtung der Förderschnecke 5 gelegen unterhalb der Trichterschräge des Vorratsbehälters 3 und dabei insbesondere innerhalb der Umfangskontur des Gestells 1 befindet. Diese Förderschnecke 5 mündet in einem auswechselbaren Dosierrohr 7 mit einer Dosierschnecke 8 und zwar im Anschluß an eine im Vorratsbehälter 3 seitlich ausgebildete Öffnung 9. Außen am Vorratsbehälter 3 ist an der Öffnung 9 eine Mischeinrichtung 10 mit einem Mischerrohr 11 mit darin befindlicher Mischerwelle 12 befestigt. Das Mischerrohr 11 ist dabei weiterhin mit zwei Wasserzuführungen 13 versehen. Die entsprechenden Wasseranschlußleitungen sind nicht dargestellt. Oberseitig weist der Vorratsbehälter 3 noch einen Deckel 14 auf, welcher eine entsprechende Öffnung 15 auf der Oberseite des Vorratsbehälters 3 verschließt.The basic version of the mortar mixing machine shown in FIGS. 1 to 6 has a rectangular frame 1 in Euro-pallet size (80 x 120 cm) and is stackable. This Frame 1 has feet 2 which can be pulled out to different heights and which are shown in broken lines. This means that any standard mortar pump and other vessels of different heights can be loaded. Inside the frame there is a funnel-shaped storage container 3, which tapers conically downwards, as can be seen in particular from the illustrations in FIGS. 2 to 4. The two inclined walls have a different angle of inclination. The slipping of the dry mortar is guaranteed. In addition, the storage container 3 has a level indicator. This storage container 3 also serves as a transport container. A conveyor device 4 with a screw conveyor 5 is arranged in the bottom region of this storage container 3. This screw conveyor 5 is driven by an electric motor 6, which is located in the axial direction of the screw conveyor 5 below the hopper slope of the storage container 3 and in particular is located within the circumferential contour of the frame 1. This screw conveyor 5 opens into an interchangeable metering tube 7 with a metering screw 8, specifically following an opening 9 formed laterally in the storage container 3. Outside of the storage container 3, a mixing device 10 with a mixer tube 11 with a mixer shaft 12 therein is fastened to the opening 9. The mixer tube 11 is further provided with two water inlets 13. The corresponding water connection lines are not shown. The upper side of the storage container 3 also has a cover 14 which closes a corresponding opening 15 on the upper side of the storage container 3.

Die so ausgebildete und in den Fig. 1 bis 6 dargestellte Grundversion der Mörtelmischmaschine funktioniert wie folgt:The basic version of the mortar mixing machine designed in this way and shown in FIGS. 1 to 6 functions as follows:

Im Nichtgebrauchszustand der Mörtelmischmaschine ist die Mischeinrichtung 10 mit dem Mischerrohr 11 und der darin befindlichen Mischerwelle 12 abmontiert und unterhalb der Trichterschräge des Vorratsbehälters 3 befestigt, wie dies in Fig. 3 angedeutet ist. Alle erforderlichen Komponenten sind somit im Gerät mit E-Palettenmaß für den Transport bzw. Betrieb untergebracht. Insbesondere gibt es beim Transport keine Überstände. Außerdem ist eine optimale Raum- und Gewichtsauslastung auf Transportfahrzeugen gewährleistet. Durch einen tiefliegenden Schwerpunkt und gleichbleibenden Querschnitt ist keine Transportsicherung notwendig. Nach dem Befüllen des Vortatsbehälters 3 mit Trockenmörtel wird die gesamte Mörtelmischmaschine am Bedarfsort aufgestellt, und die Mischeinrichtung 10 wird an der Öffnung 9 des Vorratsbehälters 3 mittels eines Verschlußspanners 16 befestigt, wie dies insbesondere in Fig. 6 erkennbar ist. Dabei wird auch die Mischerwelle 12 mit der Förderschnecke 5 gekuppelt. Außerdem wird die Wasserleitung an die Wasserzuführung 13 angeschlossen.When the mortar mixer is not in use, the mixing device 10 with the mixer tube 11 and the mixer shaft 12 located therein is removed and fastened below the hopper slope of the storage container 3, as indicated in FIG. 3. All necessary components are therefore housed in the device with e-pallet size for transport or operation. In particular, there are no protrusions during transport. In addition, optimal space and weight utilization on transport vehicles is guaranteed. Due to a low center of gravity and a constant cross-section, no transport lock is necessary. After filling the supply container 3 with dry mortar, the entire mortar mixing machine is set up at the required location, and the mixing device 10 is fastened to the opening 9 of the storage container 3 by means of a closure clamp 16, as can be seen in particular in FIG. 6. The mixer shaft 12 is also coupled to the screw conveyor 5. In addition, the water pipe is connected to the water supply 13.

Zum Betrieb der Mörtelmischmaschine wird mittels des Elektromotors 6 die Förderschnecke 5 in eine Drehbewegung versetzt. Im übrigen kann der Antriebsmotor über einen Schnellverschluß sowie ein Drehgelenk abgenommen werden. Der Trockenmörtel wird dabei durch die Förderschnecke 5 der Dosierschnecke 8 zugeführt. Die Dosierschnecke 8 fördert eine konstante Menge Trockenmörtel in das angeflanschte Mischerrohr 11 der Mischeinrichtung 10. Durch das installierte Wasserdosiersystem wird die erforderliche Menge Wasser dem Mischerrohr 11 zugeführt. Die darin befindliche Mischerwelle 12 arbeitet das Gemisch zu Naßmörtel auf, welcher durch die Mischerrohröffnung ausgetragen wird. Die Wasserzufuhr wird dabei mittels eines Magnetventils gesteuert, welches mit der Steuerung des Elektromotors 6 gekoppelt ist. Durch eine integrierte Sondensteuerung kann dabei die Mörtelmischmaschine vollautomatisch arbeiten, wobei ein Fühler/Taster die Kontrolle über den benötigten Naßmörtel übernimmt, welche in jedes Mörtelgefäß oder Pumpe aufgegeben werden kann. Bedienungspersonal ist somit nicht erforderlich. Bei Arbeitsende ist lediglich das Mischerrohr 11 zu demontieren und mit Wasser auszuspülen. Der sich im Vorratsbehälter befindliche Trockenmörtel kann dort verbleiben oder wird über eine Entleeröffnung ausgebracht. Wird bei der Verarbeitung ausschließlich Trockenmörtel benötigt, so ist lediglich die Wasserzufuhr abzustellen.To operate the mortar mixing machine, the screw conveyor 5 is set into a rotary movement by means of the electric motor 6. In addition, the drive motor can be removed via a quick release and a swivel joint. The dry mortar is fed through the screw conveyor 5 to the metering screw 8. The metering screw 8 conveys a constant amount of dry mortar into the flanged mixer pipe 11 of the mixing device 10. The required amount of water is supplied to the mixer pipe 11 through the installed water metering system. The mixer shaft 12 located therein works the mixture into wet mortar, which is discharged through the mixer pipe opening. The water supply is controlled by means of a solenoid valve which is coupled to the control of the electric motor 6. Thanks to an integrated probe control, the mortar mixing machine can work fully automatically, with a sensor / pushbutton taking control of the required wet mortar, which can be placed in any mortar container or pump. Operating personnel are therefore not required. At the end of work, only the mixer pipe 11 has to be dismantled and rinsed with water. The dry mortar in the storage container can remain there or is spread out through an emptying opening. If only dry mortar is required for processing, only the water supply has to be switched off.

Der Transport der Mörtelmischmaschine kann mit allen gängigen Hubwagen, Staplern sowie Kranen durchgeführt werden. Durch die eingehaltenen Euro-Paletten-Maße (80 x 120 cm) ist die optimale Ausnutzung der LKW-Ladeflächen sowie weiterhin eine Hochregallagerfähigkeit gegeben. Für den Transport auf einem LKW oder einem Anhänger sind lediglich die ausziehbaren Füße 2 einzuschieben. Die Mischmaschine ist dabei von allen Seiten mit allen Flurförderfahrzeugen transportierbar. In der innerbetrieblichen Logistik ist sie mit Rollenbahn sowie Kettenförderer für eine automatische Befüllung transportierbar. Bedingt durch den niedrigen Schwerpunkt wird eine zusätzliche Transportsicherung überflüssig. Zur Reinigung und Restentleerung sind der Misch- und Elektroantrieb durch Schnellverschlüsse ohne weiteres demontierbar. Schließlich ist die Mischmaschine auch im Regen ohne zusätzliche Abdeckung einsetzbar.The mortar mixing machine can be transported with all standard lifting trucks, forklifts and cranes. The adherence to the Euro pallet dimensions (80 x 120 cm) ensures optimal utilization of the truck loading areas as well as high shelf storage capacity. For transport on a truck or a trailer, only the extendable feet 2 have to be inserted. The mixer can be transported from all sides with all industrial trucks. In internal logistics, it can be transported with a roller conveyor and chain conveyor for automatic filling. Due to the low center of gravity, an additional transport lock is not necessary. The mixing and electric drive can be easily dismantled for quick cleaning and emptying. Finally, the mixer can also be used in the rain without additional cover.

In Fig. 7 ist die erfindungsgemäße Weiterentwicklung der Mörtelmischmaschine dargestellt. Die Mörtelmischmaschine an sich unterscheidet sich nicht von der, wie sie in den Fig. 1 bis 6 dargestellt und entsprechend beschrieben worden ist. Der Unterschied besteht in einem zusätzlichen Nachfüllbehälter 17, welcher auf das Gestell 1 der eigentlichen Mörtelmischmaschine aufgesetzt werden kann, wie dies in Fig. 7 erkennbar ist. Dieser Nachfüllbehälter 17 weist dabei eine entsprechende palettenfähige Querschnittsgestalt auf.7 shows the further development of the mortar mixing machine according to the invention. The mortar mixing machine itself does not differ from that as has been shown in FIGS. 1 to 6 and has been described accordingly. The difference consists in an additional refill container 17, which can be placed on the frame 1 of the actual mortar mixing machine, as can be seen in FIG. 7. This refill container 17 has a corresponding cross-sectional shape suitable for pallets.

Unterseitig weist der Nachfüllbehälter 17 eine Öffnung 18 auf. Diese liegt oberhalb der Öffnung 15 des Vorratsbehälters 3, nachdem der entsprechende Deckel 14 geöffnet worden ist. Die Verbindung zwischen dem Nachfüllbehälter 17 und dem Vorratsbehälter 3 erfolgt über eine Verbindungsleitung in Form eines zieharmonikaartigen Rohres. Dieses ist an der Öffnung 18 des Nachfüllbehälters 17 fest angeordnet und wird nach dem Nachuntenziehen auf der Öffnung 15 des Vorratsbehälters 3 entsprechend angeflanscht.The refill container 17 has an opening 18 on the underside. This lies above the opening 15 of the storage container 3 after the corresponding cover 14 has been opened. The connection between the refill container 17 and the storage container 3 takes place via a connecting line in the form of an accordion-like tube. This is fixed at the opening 18 of the refill container 17 and is flanged accordingly after pulling down on the opening 15 of the storage container 3.

Diese Ausführungsform der Mörtelmischmaschine in Fig. 7 mit der erfindungsgemäßen Erweiterung mit einem Nachfüllbehälter 17 in einer ersten Version funktioniert wie folgt:This embodiment of the mortar mixing machine in FIG. 7 with the extension according to the invention with a refill container 17 in a first version works as follows:

Bereits während des Betriebs der Mörtelmischmaschine kann auf das Gestell 1 der Nachfüllbehälter 17 in der dargestellten Weise aufgesetzt werden. Es erfolgt die Verbindung über die Verbindungsleitung 19 zu dem Vorratsbehälter 3. Bei Bedarf kann dann durch Öffnen einer entsprechenden Klappe der Durchlaß des im Nachfüllbehälter 17 befindlichen Trockenmörtels in den Vorratsbehälter 3 erfolgen. Nachdem der Nachfüllbehälter 17 leer ist, wird er abgenommen und gegebenenfalls durch einen gefüllten ersetzt. Somit ist durch die Kombination des Vorratsbehälters 3 mit dem Nachfüllbehälter 17 der Vorrat an Trockenmörtel auf über 2 Tonnen erweiterbar.Already during the operation of the mortar mixing machine, the refill container 17 can be placed on the frame 1 in the manner shown. The connection is made via the connecting line 19 to the storage container 3. If necessary, the dry mortar located in the refill container 17 can then be opened into the storage container 3 by opening a corresponding flap. After the refill container 17 is empty, it is removed and, if necessary, replaced by a filled one. Thus, by combining the storage container 3 with the refill container 17, the supply of dry mortar can be expanded to over 2 tons.

In Fig. 8 ist eine etwas modifizierte Ausführungsform des Nachfüllbehälters 17 dargestellt. Bei dieser Variante ist der Nachfüllbehälter 17 als flexibler Behälter ausgebildet, welcher in ein oberhalb des Vorratsbehälters 3 befestigbares Gestell 20 einhängbar ist. Dieser flexible Behälter für Schüttgüter wird üblicherweise als Nachschubeinheit von der Produktionsstätte zur Baustelle benutzt, wobei er aus einem lichtbeständigen sowie wasserfesten Material besteht und den großen Vorteil hat, daß er im zusammengelegten Zustand nur geringe Rücktransportkosten zur Wiederbefüllung aufweist, wobei die Nutzungsdauer bei ungefähr 5 Jahren liegt. Zur staubfreien und wasserdichten Übergabe aus dem flexiblen Nachfüllbehälter 17 in den Vorratsbehälter 3 wird ein Übergangsstück 21 auf den Vorratsbehälter 3 gelegt. Der Auslaufschlauch 22 des flexiblen Nachfüllbehälters 17 ist doppelt ausgeführt und ragt einmal in das Innere des Übergangsstücks 21 und zum anderen wird er über das Übergangsstück 21 außen gestülpt. Ein Verrutschen des Auslaufschlauchs 22 auf dem Übergangsstück 21 wird mittels einer Sackschnalle 23 verhindert.8 shows a somewhat modified embodiment of the refill container 17. In this variant, the refill container 17 is designed as a flexible container which can be suspended in a frame 20 which can be fastened above the storage container 3. This flexible container for bulk goods is usually used as a replenishment unit from the production site to the construction site, whereby it consists of a light-resistant and waterproof material and has the great advantage that it has only low return transport costs for refilling when folded, the useful life being about 5 years lies. For the dust-free and watertight transfer from the flexible refill container 17 into the storage container 3, a transition piece 21 is placed on the storage container 3. The outlet hose 22 of the flexible refill container 17 is double and protrudes into the interior of the transition piece 21 and on the other hand it is placed over the transition piece 21 on the outside. Slipping of the outlet hose 22 on the transition piece 21 is prevented by means of a bag buckle 23.
