Description
Die Erfindung betrifft eine mobile Mischvorrichtung zur örtlich unabhängigen Herstellung von Mörtel, z.B. am Ort einer Baustelle. Ein Einsatzgebiet ist z.B. die Herstellung von Estrich für Estrichböden. Unter Mörtel im Sinne der Erfindung wird aber jede Komposition aus einem Bindemittel mit Feststoff-Zuschlag, insbesondere in Verbindung mit Wasser verstanden.The invention relates to a mobile mixing device for locally independent production of mortar, e.g. at the site of a construction site. One area of application is e.g. the production of screed for screed floors. However, mortar within the meaning of the invention is any composition of a binder with added solids, particularly in combination with water.
Aus dem Stand der Technik sind beispielsweise mobile Mischvorrichtungen bekannt, die einen Vorratsbehälter zur Aufnahme wenigstens einer Mörtelkomponente, eine Mischkesselanordnung zur Mischung wenigstens einer Mörtelkomponente mit Wasser und ein Fördersystem zur Förderung der wenigstens einer Mörtelkomponente aus dem Vorratsbehälter in die Kesselanordnung, umfassen. Die aus dem Stand der Technik bekannten Vorrichtungen umfassen dabei nur einen einzigen Mischkessel in der Mischkesselanordnung.Mobile mixing devices are known from the prior art, for example, which comprise a storage container for receiving at least one mortar component, a mixing tank arrangement for mixing at least one mortar component with water, and a conveying system for conveying the at least one mortar component from the storage tank into the boiler arrangement. The devices known from the prior art include only a single mixing tank in the mixing tank arrangement.
Bei einer mobilen Mischvorrichtung, deren Mischkesselanordnung genau einen einzigen Mischkessel umfasst, liegt das Problem vor, dass ausschließlich nur in diesem einen Mischkessel eine Beschickung, Mischung und Förderung von Mörtel möglich ist. Somit entsteht zwischen dem Zeitpunkt der vollständigen Ausbringung des Mörtels aus dem Mischkessel und dem Zeitpunkt einer vollständigen neuen Beschickung und Mischung der Mörtelkomponenten eine nicht nutzbare Wartezeit.In the case of a mobile mixing device, the mixing tank arrangement of which comprises precisely one mixing tank, the problem arises that charging, mixing and conveying of mortar is only possible in this one mixing tank. Thus, there is an unusable waiting time between the time when the mortar is completely discharged from the mixing tank and the time when the mortar components are completely reloaded and mixed.
In dieser Wartezeit ist eine Ausbringung des Mörtels durch den Förderauslass aufgrund von fehlendem gemischtem Mörtel nicht möglich, vielmehr muss dadurch die Ausbringung unterbrochen werden. Mit der Wiederaufnahme der Ausbringung des Mörtels kann aus zeitlicher Sicht, erst nach vollständiger Neubeschickung mit wenigstens einer Mörtelkomponente des einen Mischkessels und Mischung der wenigstens einen Mörtelkomponente mit Wasser, begonnen werden. Die Ausbringung des Mörtels steht demnach in zeitlicher Abhängigkeit mit der vollständigen Beschickung und Mischung des Mörtels.During this waiting time, it is not possible to apply the mortar through the conveying outlet due to a lack of mixed mortar; instead, the application must be interrupted as a result. With the resumption of the application of the mortar can from a time point of view, only after complete reloading with at least one mortar component of a mixing tank and mixing the at least one mortar component with water. The application of the mortar is therefore dependent on the time when the mortar is completely charged and mixed.
Des Weiteren kann mit einer solchen bekannten Vorrichtung auch nur eine einzige Mörtelrezeptur angefertigt und zu einer bestimmten Zeit genutzt werden.Furthermore, with such a known device, only a single mortar recipe can be prepared and used at a specific time.
Es ist somit eine Aufgabe der Erfindung, eine Vorrichtung bereitzustellen, die einerseits eine größere Variabilität bei der Mörtelherstellung ermöglicht und mit der andererseits die Wartezeiten zwischen Mischkesselbefüllung und Förderung reduziert werden können.It is therefore an object of the invention to provide a device which, on the one hand, enables greater variability in mortar production and, on the other hand, can be used to reduce the waiting times between filling the mixing tank and conveying.
Diese Aufgabe wird dadurch gelöst, dass eine Vorrichtung gemäß der Erfindung innerhalb der Kesselanordnung wenigstens zwei, vorzugsweise genau zwei Mischkessel umfasst.This object is achieved in that a device according to the invention comprises at least two, preferably exactly two, mixing tanks within the tank arrangement.
Die Ausstattung mit wenigstens zwei Mischkesseln in der Mischkesselanordnung bietet einerseits den Vorteil gleichzeitig zwei verschiedene Mörtelrezepturen bereitstellen zu können und andererseits auch die Möglichkeit eines kontinuierlichen Förderbetriebes des fertigen Mörtels, insbesondere von nur einer Rezeptur, zur Baustelle, wenn nämlich aus/mit einem, insbesondere druckluftbeaufschlagten, Mischkessel fertig gemischter Mörtel zur Baustelle gefördert wird, während in wenigstens einem, vorzugsweise genau einem anderen Mischkessel bereits neuer Mörtel aus der wenigstens einen Mörtelkomponente und Wasser vorbereitet wird. Die im Stand der Technik unvermeidbaren Ausfallzeiten kommen bei der Erfindung nicht vor oder werden zumindest deutlich reduziert.The equipment with at least two mixing tanks in the mixing tank arrangement offers the advantage on the one hand of being able to provide two different mortar recipes at the same time and on the other hand also the possibility of a continuous conveying operation of the finished mortar, in particular of only one recipe, to the construction site, if namely from/with one, in particular pressurized air , Mixing tank of ready-mixed mortar is conveyed to the construction site, while new mortar from the at least one mortar component and water is already being prepared in at least one, preferably precisely one other mixing tank. The downtimes that are unavoidable in the prior art do not occur with the invention or are at least significantly reduced.
Vorzugsweise ist die Vorrichtung durch ein örtlich variables Fördersystem flexibler einsetzbar.The device can preferably be used more flexibly thanks to a locally variable conveyor system.
Dabei umfasst das Fördersystem wenigstens eine Fördereinheit, insbesondere die als eine Förderschnecke oder ein Förderband ausgebildet ist. Die wenigstens eine Fördereinheit ist vorgesehen und eingerichtet, um wenigstens eine Mörtelkomponente aus dem Vorratsbehälter in Richtung zur Mischkesselanordnung zu befördern.In this case, the conveyor system comprises at least one conveyor unit, which is in particular designed as a conveyor screw or a conveyor belt. The at least one conveyor unit is provided and set up to at least one To carry mortar component from the reservoir towards the mixing tank assembly.
Die Erfindung kann vorsehen, dass durch örtliche Verlagerung der Fördereinheit alternativ dem einen oder dem anderen Mischkessel wenigstens eine Mörtelkomponente aus dem Vorratsbehälter zuführbar ist. Dafür kann z.B. ein dem Vorratsbehälter nahes Ende der Fördereinheit am Vorratsbehälter angelenkt sein, d.h. damit beweglich verbunden sein. Ein auslaßseitiges Ende der Fördereinheit kann sodann alternativ relativ zu dem einen oder den wenigstens einen anderen Mischkessel positioniert werden, z.B. jeweils über einem Einfülltrichter des Mischkessels.The invention can provide that at least one mortar component from the reservoir can alternatively be supplied to one or the other mixing tank by local relocation of the conveying unit. For this purpose, for example, an end of the conveyor unit close to the storage container can be hinged to the storage container, i.e. it can be movably connected thereto. An outlet-side end of the conveying unit can then alternatively be positioned relative to the one or the at least one other mixing tank, e.g. in each case above a hopper of the mixing tank.
Zusätzlich oder alternativ dazu können die wenigstens zwei Mischkessel, mithilfe eines Schienensystems, abwechselnd, relativ zu einer Fördereinheit positioniert werden, z.B. mit dem jeweiligen Einfülltrichter unter dem auslaßseitigen Ende einer Fördereinheit. In einem solchen Fall kann eine Fördereinheit auch örtlich fixiert sein. Dadurch kann einem der Mischkessel der Mischkesselanordnung die wenigstens eine Mörtelkomponente aus dem Vorratsbehälter durch die Fördereinheit zugeführt werden.In addition or as an alternative to this, the at least two mixing tanks can be positioned alternately relative to a conveyor unit with the aid of a rail system, e.g. with the respective hopper under the outlet end of a conveyor unit. In such a case, a conveyor unit can also be fixed locally. As a result, the at least one mortar component from the reservoir can be supplied by the conveyor unit to one of the mixing tanks of the mixing tank arrangement.
Anders als beim Stand der Technik ist es mit einer solchen Vorrichtung somit möglich, eine kontinuierliche Förderung von Mörtel bereit zu stellen.In contrast to the prior art, it is thus possible with such a device to provide continuous delivery of mortar.
Insbesondere besteht so die Möglichkeit, einen ersten Mischkessel mit wenigstens einer Mörtelkomponente zu beschicken und diese mit Wasser zu mischen und gleichzeitig aus einem anderen Mischkessel, z.B. dem zweiten Mischkessel den bereits fertig gemischten Mörtel zu fördern, z.B. durch dessen Förderauslass zu fördern. Dadurch wird der zeitliche Ablauf von Zubereitung und Förderung von Mörtel optimiert und eine kontinuierliche Förderung kann sichergestellt werden.In particular, there is the possibility of charging a first mixing tank with at least one mortar component and mixing it with water and at the same time conveying the ready-mixed mortar from another mixing tank, e.g. the second mixing tank, e.g. through its delivery outlet. This optimizes the timing of the preparation and delivery of mortar and continuous delivery can be ensured.
Bei einer Vorrichtung gemäß der Erfindung handelt es sich um eine Mischkesselanordnung die wenigstens zwei Mischkessel umfasst. In bevorzugter Ausführung umfasst die Mischkesselanordnung vorzugsweise genau zwei Mischkessel. Dadurch ist es möglich die Mischkessel zeitgleich in verschiedenen Betriebsmodi zu betreiben.A device according to the invention is a mixing tank arrangement which comprises at least two mixing tanks. In a preferred embodiment, the mixing tank arrangement preferably comprises exactly two mixing boiler. This makes it possible to operate the mixing tanks in different operating modes at the same time.
Zum einen in einem Mörtelkomponenten-Fördermodus/Mischmodus, bei dem aus dem Vorratsbehälter wenigstens eine Mörtelkomponente entnehmbar und mithilfe des Fördersystems aus dem Vorratsbehälter in die Mischkesselanordnung, insbesondere einem von deren Mischkesseln, gefördert und die wenigstens eine Mörtelkomponente mit Wasser in der Mischkesselanordnung gemischt wird. Zum anderen in einem Ausbringmodus, bei dem der gemischte Mörtel ausgebracht wird.On the one hand in a mortar component delivery mode/mixing mode, in which at least one mortar component can be removed from the storage container and is conveyed with the aid of the delivery system from the storage container into the mixing tank arrangement, in particular one of its mixing tanks, and the at least one mortar component is mixed with water in the mixing tank arrangement. On the other hand in an application mode in which the mixed mortar is applied.
Vorteilhaft hierbei ist, dass durch eine Verwendung von zwei Mischkesseln keine Pausen zwischen dem Mörtelkomponenten-Fördermodus/Mischmodus und dem Ausbringmodus des Mörtels entstehen. Dadurch kann eine kontinuierliche Förderung des Mörtels und eine schnelle Bearbeitung, z.B. der Estrichböden gewährleistet werden.The advantage here is that the use of two mixing tanks means that there are no breaks between the mortar component delivery mode/mixing mode and the dispensing mode of the mortar. This ensures continuous delivery of the mortar and fast processing, e.g. of the screed floors.
Die Vorrichtung kann eine Steuerung umfassen, die eingerichtet ist, die vorgenannten Betriebsmodi zu steuern, insbesondere auszuwählen, vorzugsweise auch in Abhängigkeit von Eingangsparametern, z.B. einer Beladung. Mit der Steuerung wird weiterhin die Befüllung koordiniert, z.B. die Verlagerung der Fördereinheit und/oder die Verschiebung der Mischkesselanordnung.The device can include a controller that is set up to control the aforementioned operating modes, in particular to select them, preferably also as a function of input parameters, e.g. a load. The controller also coordinates the filling, e.g. relocating the conveyor unit and/or relocating the mixing tank arrangement.
Die wenigstens eine Mörtelkomponente gemäß der Erfindung setzt sich aus einem Bindemittel, z.B. Zement, Kalk oder Lehm und einem je nach Anwendungsfall in der Korngröße variablen Feststoff-Zuschlag, z.B. Sand, Kies zusammen. Der Mörtel ergibt sich aus der Mischung von wenigstens einer Mörtelkomponente und der Zuführung von Wasser, z.B. über einen Schlauch, z.B. von der Baustelle. Es kann eine Mörtelmischung auch aus mehreren verschiedenen Mörtelkomponenten erstellt werden, vorzugsweise die separat in dem Vorratsbehälter bevorratet werden.The at least one mortar component according to the invention consists of a binder, e.g. cement, lime or clay and a solid additive, e.g. sand or gravel, which can vary in grain size depending on the application. The mortar results from the mixing of at least one mortar component and the supply of water, e.g. via a hose, e.g. from the construction site. A mortar mixture can also be created from several different mortar components, which are preferably stored separately in the reservoir.
Die Zuführung der Mörtelkomponenten erfolgt durch das in die Vorrichtung integrierte Fördersystem. Dabei ist der Vorratsbehälter vorzugsweise als Mulde, insbesondere doppelwandige Aluminiummulde, ausgebildet. Die zur Förderung der Mörtelkomponente geeignete Mulde ist in bevorzugter Ausführung ein von oben befüllbarer, mit einer Plane vor Witterungseinflüssen schützbarer Vorratsbehälter in einem Anhänger, LKW oder in einem auf eine Zugmaschine auflegbaren Auflieger, vorzugsweise, z.B. einen drei oder mehrachsigen Sattelauflieger integriert. Je nach Art und Anwendung der Mörtelkomponenten kann die Mulde ein Fassungsvermögen von bis zu 50m3 umfassen.The mortar components are fed in by the conveyor system integrated into the device. The reservoir is preferably designed as a trough, in particular double-walled aluminum trough. In a preferred embodiment, the trough suitable for promoting the mortar component is a reservoir that can be filled from above and can be protected from the weather with a tarpaulin in a trailer, truck or in a semitrailer that can be placed on a tractor unit, preferably integrated, for example, in a three- or multi-axle semitrailer. Depending on the type and application of the mortar components, the trough can have a capacity of up to 50m 3 .
Um eine Durchmischung der Mörtelkomponenten zu verhindern und einen Transport verschiedener Mörtelkomponenten zu ermöglichen, umfasst die Mulde wenigstens eine Kammer, vorzugsweise wenigstens zwei Kammern. Damit ist die genannte Bevorratung unterschiedlicher Mörtelkomponenten und die Herstellung verschiedener Mörtelarten möglich und variabel einstellbar.In order to prevent the mortar components from being mixed up and to enable different mortar components to be transported, the trough comprises at least one chamber, preferably at least two chambers. This means that the storage of different mortar components and the production of different types of mortar is possible and variably adjustable.
Um eine Zuführung der Mörtelkomponenten aus dem Vorratsbehälter in die Kesselanordnung zu erleichtern ist die Mulde vorzugsweise um eine Drehachse kippbar gelagert ausgebildet. Eine Zuführung der Mörtelkomponenten ist in bevorzugter Ausführung durch das Verkippen des Vorratsbehälters, z.B. durch Verrutschen der wenigstens einen Mörtelkomponente und/oder mithilfe des Fördersystems durch die Förderung der wenigstens einen Mörtelkomponente aus dem Vorratsbehälter in einen der Mischkessel möglich.In order to make it easier to feed the mortar components from the storage container into the boiler arrangement, the trough is preferably designed so that it can be tilted about an axis of rotation. In a preferred embodiment, the mortar components can be fed in by tilting the storage container, e.g. by slipping the at least one mortar component and/or with the aid of the conveyor system by conveying the at least one mortar component from the storage container into one of the mixing tanks.
In der erfindungsgemäßen Vorrichtung ist es bevorzugt vorgesehen, dem ersten Mischkessel im Mörtelkomponenten-Fördermodus/Mischmodus wenigstens eine Mörtelkomponente aus dem Vorratsbehälter zuzuführen, während sich der zweite Mischkessel im Ausbringmodus befindet. Ein zeitgleicher Betrieb der Mischkessel einerseits im Fördermodus/Mischmodus und andererseits im Ausbringmodus ist mithilfe der erfindungsgemäßen Vorrichtung möglich.In the device according to the invention, it is preferably provided that at least one mortar component is fed from the reservoir to the first mixing tank in the mortar component delivery mode/mixing mode, while the second mixing tank is in dispensing mode. Simultaneous operation of the mixing tanks, on the one hand, in conveying mode/mixing mode and, on the other hand, in dispensing mode, is possible with the aid of the device according to the invention.
In einer erfindungsgemäßen Vorrichtung kann es bevorzugt vorgesehen sein, durch eine Beladungserkennung den Zeitpunkt, z.B. in Abhängigkeit der Beladungsmenge, zu detektieren zu dem einer der Mischkessel den Mörtelkomponenten-Fördermodus/Mischmodus des anderen Mischkessels initialisiert, z.B. beim detektierten Unterschreiten eines vorgesehenen, z.B. gespeicherten, Beladungsgrenzwertes.In a device according to the invention, provision can preferably be made for a load detection system to detect the point in time at which one of the mixing tanks changes the mortar component delivery mode/mixing mode of the other mixing tank, for example as a function of the load quantity initialized, for example, when it is detected that a planned, for example stored, load limit value is not reached.
Zusätzlich zu der Beladungserkennung ist vorzugsweise bei der Zuführung der Mörtelkomponenten eine Dosiererkennung vorgesehen. Mithilfe der Dosiererkennung werden die Mörtelkomponenten verwiegend oder volumetrisch den Mischkesseln zugeführt. Damit kann die exakte Zuführung der Mörtelkomponenten im Fördermodus gewährleistet werden. Für Beladungserkennung und Dosierungserkennung kann z.B. dieselbe Wägevorrichtung verwendet werden.In addition to the load detection, a dosing detection is preferably provided when the mortar components are fed. With the help of the dosing detection, the mortar components are weighed or fed volumetrically to the mixing tanks. This ensures the exact feeding of the mortar components in the conveying mode. For example, the same weighing device can be used for load detection and dosage detection.
Über eine in einem Schaltschrank befindliche, z.B. computerbasierte Steuerung ist die Zuführung von Mörtelkomponenten protokolierbar, mögliche Rezepturen hinterlegbar und diese automatisiert abarbeitbar. Daraus ergibt sich ein zusätzlicher Vorteil der Vorrichtung der in der erleichterten Bedienbarkeit liegt, sodass mit wenig Bedienpersonal, z.B. ein bis zwei Mitarbeitern, eine Bedienung der Vorrichtung erfolgen kann.The supply of mortar components can be logged, possible recipes can be stored and these can be processed automatically via a computer-based control system located in a control cabinet. This results in an additional advantage of the device, which is that it is easier to operate, so that the device can be operated with few operating personnel, e.g. one or two employees.
In einer bevorzugten Ausführung umfasst jeder Mischkessel ein Rührwerk, wobei die Rührwerke sukzedan oder simultan durch wenigstens einen Motor antreibbar sind, vorzugsweise aber jedes Rührwerk mit einem eigenen Motor zumindest im Mischmodus, insbesondere auch im Ausbringmodus, angetrieben ist. Ist die wenigstens eine Mörtelkomponente, ggfs. mehrere Mörtelkomponenten mit Wasser zu einem fertigen Mörtel gemischt, so kann dieser im Ausbringmodus aus dem betreffenden Mischkessel ausgebracht werden.In a preferred embodiment, each mixing vessel comprises an agitator, with the agitators being able to be driven successively or simultaneously by at least one motor, but preferably each agitator is driven by its own motor at least in mixing mode, in particular also in dispensing mode. If the at least one mortar component, possibly several mortar components, are mixed with water to form a ready-made mortar, then this can be discharged from the mixing tank in question in the discharge mode.
In einer bevorzugten Ausführung kann jeder Mischkessel einen eigenen Förderauslass umfassen. Dabei kann die Ausbringung durch Zugabe von Druckluft auf den Mischkessel, insbesondere nach dessen druckdichtem Verschließen, unterstützt werden. Jeder Förderauslass ist in bevorzugter Ausführung an eine umschaltbare Weiche angeschlossen. Darüber kann die Ausbringung über einen gemeinsamen Förderschlauch erfolgen. Mit der Weiche ist der gemeinsame Förderschlauch an den Mischkessel anschaltbar, in dem fertig gemischter Mörtel zur Ausbringung vorliegt. Die Weiche kann z.B. durch die Druckbeaufschlagung des Mischkessels gesteuert sein, insbesondere automatisch durch die genannte Steuerung. Z.B. kann es vorgesehen sein, dass automatisch der Förderauslass desjenigen Mischkessels über die Weiche an den gemeinsamen Förderschlauch angeschlossen wird, dessen Druckniveau einen vorbestimmten Grenzwert überschreitet.In a preferred embodiment, each mixing tank can have its own conveying outlet. The discharge can be supported by adding compressed air to the mixing tank, especially after it has been sealed pressure-tight. In a preferred embodiment, each conveyor outlet is connected to a switchable diverter. In addition, the discharge can take place via a common conveying hose. With the switch, the common delivery hose can be connected to the mixing tank, in which it's done mixed mortar is available for application. The switch can be controlled, for example, by the pressurization of the mixing tank, in particular automatically by the controller mentioned. For example, it can be provided that the conveying outlet of that mixing tank is automatically connected via the switch to the common conveying hose whose pressure level exceeds a predetermined limit value.
In einer ersten Ausführungsform erfolgt eine Förderung der Mörtelkomponenten über eine vom Fördersystem umfasste, variabel positionierbare Fördereinheit mit der die wenigstens eine Mörtelkomponente transportierbar ist. Die Fördereinheit weist vorzugsweise eine Förderschnecke oder ein Förderband auf. Dabei ist die Fördereinheit z.B. an einem schwenkbaren Arm befestigt wodurch eine örtliche Verlagerung der Fördereinheit und damit eine Positionierung oberhalb des Einfülltrichters des ersten oder des zweiten Mischkessels erfolgt. Dadurch ist alternativ dem einen oder dem anderen Mischkessel wenigstens eine Mörtelkomponente zuführbar. Über die Einfülltrichter wird eine zielgenaue und sichere Beschickung der Mischkessel aus dem Vorratsbehälter ermöglicht.In a first embodiment, the mortar components are conveyed via a variably positionable conveying unit which is included in the conveying system and with which the at least one mortar component can be transported. The conveyor unit preferably has a conveyor screw or a conveyor belt. The conveyor unit is attached to a pivoting arm, for example, which means that the conveyor unit can be relocated and positioned above the hopper of the first or second mixing tank. As a result, at least one mortar component can alternatively be supplied to one or the other mixing vessel. The filling funnel enables a precise and safe loading of the mixing tank from the storage tank.
Die erste Ausführungsform umfasst wenigstens eine Fördereinheit zur Förderung der Mörtelkomponenten. Denkbar ist ein Fördersystem, das zwei Fördereinheiten umfasst, sodass je eine Fördereinheit oberhalb eines Einfülltrichters je eines Mischkessels positionierbar ist. Eine Verlagerung der Fördereinheiten würde dadurch entfallen. Die Verwendung von zwei Fördereinheiten würde einen zusätzlichen zeitlichen Vorteil mit sich bringen, da ein "Umschalten" der Fördereinheit zwischen einer Förderung von Mörtelkomponenten zwischen dem ersten und zweiten Mischkessel entfallen würde.The first embodiment comprises at least one delivery unit for delivering the mortar components. A conveying system is conceivable which comprises two conveying units, so that one conveying unit can be positioned above a hopper for each mixing tank. This would eliminate the need for the conveying units to be relocated. The use of two conveyor units would result in an additional advantage in terms of time, since the conveyor unit would not have to "switch over" between conveying mortar components between the first and second mixing tank.
Eine zweite Ausführungsform ermöglicht eine Förderung der Mörtelkomponenten über ein vom Fördersystem umfasstes Schienensystem. Damit sind die vorzugsweise genau zwei Mischkessel der Mischkesselanordnung abwechselnd relativ zu einer, insbesondere genau einer einzigen Fördereinheit positionierbar. Vorzugsweise sind die wenigstens zwei Mischkessel auf einem Laufwagen des Schienensystems befestigt und innerhalb des Schienensystems relativ zur Fördereinheit verschiebbar. Ein solcher Laufwagen kann in wenigstens zwei vorbestimmte Positionen gefahren werden, vorzugsweise je eine bestimmte Position pro Mischkessel. Es kann vorgesehen sein, dass in jeder der Positionen ein anderer Mischkessel der Mischkesselanordnung, z.B. seinem Einfülltrichter, so zu einer Fördereinheit, z.B. dessen Auslaßende, positioniert ist, dass der Mischkessel mit der wenigstens einen Mörtelkomponente befüllbar ist.A second embodiment enables the mortar components to be conveyed via a rail system included in the conveying system. The preferably exactly two mixing tanks of the mixing tank arrangement can thus be positioned alternately relative to one, in particular exactly a single, delivery unit. The at least two mixing tanks are preferably attached to a carriage of the rail system and can be displaced within the rail system relative to the conveyor unit. Such a carriage can be moved into at least two predetermined positions, preferably one specific position for each mixing tank. Provision can be made for another mixing vessel of the mixing vessel arrangement, eg its hopper, to be positioned in each of the positions in relation to a conveying unit, eg its outlet end, such that the mixing vessel can be filled with the at least one mortar component.
Das gesamte Schienensystem ist vorzugsweise auf einem Gestell montiert, dass mit dem Anhänger, LKW oder Auflieger verbunden ist. Das Gestell kann ausfahrbare Stützen aufweisen, die eine Standfestigkeit der Vorrichtung bei Positionierung, z.B. auf unebenen Untergrund, z.B. auf einer Baustelle sicherstellen.The entire rail system is preferably mounted on a cradle that is connected to the trailer, truck or trailer. The frame can have extendable supports that ensure stability of the device when it is positioned, e.g. on uneven ground, e.g. on a construction site.
