Abstract

A transport container (1) for loose bulk material tapers at the bottom and interacts with a conveying apparatus for the bulk material. The intention is, first, that the transport container (1) should make the use of bags superfluous and secondly that the bulk material be made capable of flowing at the working position. To this end, lower oblique walls (15, 17, 18) of the transport container (1) merge at the bottom into a base trough (20) which is open towards the interior of the container and in which a longitudinal section (26.2) of the driveshaft (26), which carries conveyor paddles (30), is rotatably mounted. The drive motor (28) and a discharge pipe (22) with a mixing device are removably arranged, as is a vibrator (54) which can be attached to the transport container. The transport container has the base area of a DIN Europallet and, at the working position, can be set upon a support frame (40) which likewise has the outline of a DIN Europallet. <IMAGE>

Description

Die hier in Frage kommenden Schüttgüter sind solche, die an einer Arbeitsstelle verwendet werden können, z. B. an einer Baustelle Mörtel, Putz, Gips, Zement, Sand, Kalk. Aber auch andere Schüttgüter kommen in Frage, wie Mehl für das Bäckerhandwerk und andere Wirtschaftbereiche. Anwendbar ist der Transportbehälter nach der Erfindung überall dort, wo einerseits an einer Arbeitsstelle, wie z.B. am Bau oder im Bäckereibetrieb gemischt werden muß, andererseits aber größere Mengen der Schüttgüter über große Entfernungen, z. B. auf Lastwegen oder der Bahn befördert werden müssen.The bulk materials in question here are those that can be used at a workplace, e.g. B. at a construction site mortar, plaster, plaster, cement, sand, lime. But other bulk goods are also possible, such as flour for the bakery trade and other economic sectors. The transport container according to the invention can be used wherever, on the one hand, at a work station, such as must be mixed on site or in the bakery, but on the other hand larger quantities of bulk goods over long distances, e.g. B. must be transported on load routes or by train.

Durch die Verwendung des Behälters sollen Verpackungen entfallen, wie z.B. Papiersäcke oder Folien. Dadurch sollen Entsorgungs- und Müllprobleme vermieden werden, wie auch die Beseitigung von Restinhalten als Sondermüll.By using the container, packaging, such as Paper bags or foils. This is intended to avoid disposal and waste problems, as well as the removal of residual content as special waste.

Bekannt sind Transportbehälter, z. B. nach der US-A-3 104 035, die große Menge Schüttgut aufnehmen können, jedenfalls ein Vielfaches eines einzelnen Sackes. Derartige Transportbehälter verjüngen sich nach unten, entweder in Form eines Kegels oder in Form einer Pyramide. Die untere Öffnung ist durch eine Klappe verschließbar, und es ist erforderlich, unterhalb der Klappe noch einen Kanal vorzusehen, der die geöffnete Klappe aufnehmen kann.Transport containers are known, for. B. according to US-A-3 104 035, which can accommodate large quantities of bulk material, in any case a multiple of a single sack. Such transport containers taper downwards, either in the form of a cone or in the form of a pyramid. The lower opening can be closed by a flap, and it is necessary to provide a channel below the flap that can accommodate the opened flap.

Derartigen Transportbehältern kann ein Rohr zugeordnet werden, das eine Fördervorrichtung für das Schüttgut, z. B. in Gestalt einer Schnecke und eine Mischvorrichtung, z. B. mit Wassereinlaß enthält. Zum Transport kann eine Vorrichtung dieser Art abgenommen werden, so daß der Transportbehälter davon entlastet ist.Such transport containers can be assigned a tube that a conveying device for the bulk material, for. B. in the form of a screw and a mixing device, for. B. contains water inlet. A device of this type can be removed for transport, so that the transport container is relieved of it.

Transportbehälter dieser Art haben einen sehr ins Gewicht fallenden Nachteil: Viele Schüttgüter neigen zum Verklumpen. Dieses Verklumpen tritt besonders durch die Rüttelbewegungen beim Transport auf. Das Schüttgut verläßt dann nicht mehr ohne weiteres den nach dem Transport wieder aufgestellten Behälter. Es müssen extra Maßnahmen ergriffen werden, um das Schüttgut wieder rieselfähig zu machen, was umständlich ist und die egentliche Arbeit, z.B. am Bau, verzögert.Transport containers of this type have a very significant disadvantage: many bulk goods tend to clump together. This clumping occurs particularly due to the shaking movements during transport. The bulk material then no longer easily leaves the container that has been set up again after the transport. Extra measures have to be taken to make the bulk material flowable again, which is cumbersome and delays ordinary work, for example on construction.

Durch die vorliegende Erfindung soll zunächst ein Transportbehälter geschaffen werden, der ebenfalls sich nach unten verjüngende Schrägwände hat und der ebenfalls mit einer Fördervorrichtung zusammenarbeiten kann, der aber die Möglichkeit bieten soll, ohne zusätzlichen Arbeitsaufwand Schüttgut, das sich beim Transport festgesetzt, verdickt, verklumpt hat, wieder rieselfähig zu machen. Das Schüttgut soll direkt aus dem Behälter entnommen werden können.The present invention is initially intended to create a transport container which also has sloping walls which taper downwards and which can also work together with a conveying device, but which should, however, offer the possibility of bulk material which has become stuck, thickened and clumped during transport without additional work to make it flowable again. The bulk material should be able to be removed directly from the container.

Dies wird durch die Erfindung nach Anspruch 1 erreicht. Auf die in den Ansprüchen verwendeten Begriffe wird im folgenden Bezug genommen.This is achieved by the invention according to claim 1. The terms used in the claims are referred to below.

Im Gegensatz zu bekannten Transport behältern gehen nach der Erfindung die Schrägwände in eine Bodenwanne über, in der ein Längsabschnitt einer mit Förderpaddeln versehenen Welle gelagert ist, während ein Antriebsmotor und ein weiterer Längsabschnitt der Antriebswelle abnehmbar sind und erst an der Arbeitsstelle angebracht zu werden brauchen.In contrast to known transport containers go according to the invention, the inclined walls into a floor pan, in which a longitudinal section of a shaft provided with conveyor paddles is mounted, while a drive motor and another longitudinal section of the drive shaft are removable and need to be attached to the job.

Es wird in Kauf genommen, daß der Längsabschnitt der Antriebswelle mit Förderpaddeln das Gewicht des Containers erhäht. Es ergibt sich aber der erhebliche Vorteil, daß an der Arbeitsstelle sofort mit der Entnahme des Schüttgutes begonnen werden kann (nachdem der Antriebsmotor und der Außenbereich der Antriebswelle montiert sind). Die Förderpaddel sorgen dann dafür, daß das evetuell verklumpte Schüttgut wieder rieselfähig gemacht wird, ohne daß irgendwelche zusätzlichen Arbeitsgänge hierfür erforderlich sind.It is accepted that the longitudinal section of the drive shaft with conveyor paddles increases the weight of the container. However, there is the considerable advantage that removal of the bulk material can begin immediately at the work site (after the drive motor and the outer area of the drive shaft have been installed). The conveyor paddles then ensure that the possibly clumped bulk material is made free-flowing again without any additional operations being required for this.

Bekannt sind andererseits, z. B. aus der DE-A-31 00 443, Mischvorrichtungen, die jeweils nur an einer Arbeitstelle zu verwenden sind, z. B. an einer Baustelle. Diese haben einen relativ kleinen Behälter, meist in Form eines Trichters, der nur zur Aufnahme kleiner Mengen geeignet ist, z. B. gerade zur Aufnahme des Inhalts eines Sackes. Nach Anspruch 1 wird dagegen ein Transportbehälter geschaffen, der größere Mengen, entsprechend einer größeren Anzahl von Säcken, von Schüttgut aufnehmen kann und der dann am Zielort (der Arbeitsstelle) außerdem zur Mischung und Ausgabe des Schüttgütes dient. Verpackungsmaterial entfällt daher vollständig.On the other hand, z. B. from DE-A-31 00 443, mixing devices, which are only to be used at one place, z. B. at a construction site. These have a relatively small container, usually in the form of a funnel, which is only suitable for holding small amounts, e.g. B. just to record the contents of a sack. According to claim 1, however, a transport container is created which can accommodate larger quantities, corresponding to a larger number of bags, of bulk material and which then also serves at the destination (the place of work) for mixing and dispensing the bulk material. Packaging material is therefore completely eliminated.

WeiterbildungenTraining der Erfindungthe invention

ergeben sich aus den Unteransprüchen.result from the subclaims.

Der Transportbehälter kann ein Fassungsvermögen zwischen 800 und 2.000 Liter und im Grundriß die Abmessungen einer DIN-Europalette haben. Durch die genormte Palette wird der Transport sowohl per Bahn als auch per Lastwagen oder per Absetz-Kipp-Anhänger problemlos.The transport container can have a capacity between 800 and 2,000 liters and the dimensions of a DIN Euro pallet. Thanks to the standardized pallet, transport by train, truck or drop-off trailer is no problem.

Zur Gewichtseinsparung beim Transport läßt sich nicht nur der Antriebsmotor, sondern auch ein nach außen ragendes Ausgaberohr abnehmen. Hierdurch ergibt sich auch ein geringerer Investitionsaufwand, da man zu mehreren Transportbehältern an der Arbeitsstelle nur einen Satz von Motor und Ausgaberohr benötigt, also nicht auch für die Transportbehälter, die jeweils für die Nachlieferung von Schüttgut unterwegs sind.To save weight during transport, not only the drive motor, but also an outward projecting delivery tube can be removed. This also results in a lower investment outlay, since only one set of motor and dispensing tube is required for several transport containers at the work station, and therefore not also for the transport containers which are each on the way for the subsequent delivery of bulk goods.

Am Ausgaberohr kann ein Wassereinlaß vorgesehen sein. Dadurch wird es es möglich, die trockenen Schüttgüter vor ihrer Ausgabe mit Wasser anzumischen.A water inlet can be provided on the dispensing tube. This makes it possible to mix the dry bulk goods with water before they are dispensed.

Dadurch, daß die Antriebswelle zwischen ihrem Innenbereich, der die Förderpaddel trägt, und ihrem Außenbereich, der die Mischflügel trägt, eine Dosierschnecke hat, läßt sich das Schüttgut dosiert, direkt aus dem Behälter entnehmen, ohne daß dazu weitere Arbeitsgeräte erforderlich sind.Because the drive shaft has a metering screw between its inner area, which carries the conveyor paddles, and its outer area, which carries the mixing blades, the bulk material can be dosed directly from the container without the need for any additional tools.

Ferner kann zur Stützung des Behälters an der Arbeitsstelle ein Bock vorgesehen sein, dessen Grundriß ebenfalls die Abmessungen einer DIN-Europalette hat. Dieser Bock kann so gestaltet werden, daß oberhalb seiner Querstreben und zwischen seinen Eckpfosten freier Raum verbleibt, der zur Aufnahme sonstiger zu transportierender Gegenstände beim Tranport des Bockes genutzt werden kann.Furthermore, a trestle can be provided to support the container at the work station, the floor plan of which also has the dimensions of a DIN Euro pallet. This trestle can be designed so that above its cross struts and between its corner posts there is free space which can be used to accommodate other objects to be transported when the trestle is being transported.

Begriffe wie "lotrecht", "waagerecht" und dgl. beziehen sich auf die normale Lage von Behälter und Bock nach den Figuren 1 bis 4.Terms such as "perpendicular", "horizontal" and the like refer to the normal position of the container and trestle according to FIGS. 1 to 4.

Der als Ganzes mit 1 bezeichnete Transportbehälter (Figur 1 und 2) hat in seinem oberen Bereich lotrechte Seitenwände 3 und lotrechte Stirnwände 5. Er ist oben durch eine Deckplatte 7 abgeschlossen, in der eine Einfüllöffnung 9 vorgesehen ist. Ein Rohrstutzen 11, der die Einfüllöffnung umgibt, läßt sich durch eine kreisförmige Deckplatte 13 verschließen.The transport container designated as a whole by 1 (FIGS. 1 and 2) has vertical side walls 3 and vertical end walls 5 in its upper region. It is closed at the top by a cover plate 7 in which a filling opening 9 is provided. A pipe socket 11, which surrounds the filling opening, can be closed by a circular cover plate 13.

Die lotrechten Seitenwände 3 gehen unten in Schrägwände 15 über. Die lotrechten Stirnwände 5 gehen unten in Schrägwände 17 und 18 über. Die Schrägwände 15 gehen in eine gegen den Innenraum des Transportbehälters offene Bodenwanne 20 über. An dem in Figur 1 rechten, geschlossenen Ende der Bodenwanne setzt die Schrägwand 18 an. Dagegen ist die Bodenwanne 20 an ihrem in Figur 1 linken Ende geöffnet. Sie wird dort durch ein Ausgaberohr 22 fortgesetzt, das, ebenso wie die Bodenwanne, waagerecht verläuft, einen kreisförmigen Querschnitt hat und an seinem linken Ende einen Ausgabestutzen 24 aufweist.The vertical side walls 3 merge into inclined walls 15 below. The vertical end walls 5 merge into inclined walls 17 and 18 below. The inclined walls 15 merge into a floor pan 20 open towards the interior of the transport container. The inclined wall 18 attaches to the closed end of the floor pan on the right in FIG. 1. In contrast, the floor pan 20 is open at its left end in FIG. 1. It is continued there by an outlet pipe 22 which, like the floor pan, runs horizontally, has a circular cross section and has an outlet nozzle 24 at its left end.

Innerhalb der Bodenwanne 20, und zwar in deren Längsrichtung sowie längs der Achse des Ausgaberohres 22 verläuft eine Antriebswelle 26, die durch einen am rechten, geschlossenen Ende der Bodenwanne 20 angebrachten Antriebsmotor 28, insbesondere einen Elektromotor, antreibbar ist. Der Antriebsmotor 28 ist abnehmbar angebracht. An der Antriebswelle 26 sind in drei verschiedenen Abschnitten unterschiedliche Teile angebracht.A drive shaft 26 runs inside the floor pan 20, namely in the longitudinal direction thereof and along the axis of the dispensing tube 22, and can be driven by a drive motor 28, in particular an electric motor, attached to the right, closed end of the floor pan 20. The drive motor 28 is removably attached. Different parts are attached to the drive shaft 26 in three different sections.

In einem Innenbereich 26.2 der Antriebswelle sind Förderpaddel 30 in Gestalt von Platten angebracht, die von der Antriebswelle quer abstehen, aber so geneigt sind, als wären sie Teile von Schraubenflächen. Die Förderpaddel sind unter gegenseitigen Winkelabständen von 90° angeordnet und in Längsrichtung der Welle gegeneinander versetzt.In an inner region 26.2 of the drive shaft, conveyor paddles 30 are attached in the form of plates which project transversely from the drive shaft, but are inclined as if they were parts of screw surfaces. The conveyor paddles are arranged at mutual angular distances of 90 ° and offset in the longitudinal direction of the shaft.

In einem sich nach links anschließenden Zwischenbereich 26.4 der Antriebswelle ist eine Dosierschnecke 32 angeordnet, die als Schraubenfläche ausgebildet ist und eine Ganghöhe von 20 bis 50 mm, insbesondere 35 mm hat. In einem Außenbereich 26.6 der Antriebswelle sind Mischflügel 34 und Förderflügel 36 angebracht. Beide Arten von Flügeln sind unter gegenseitigen Winkelabständen von 90° angeordnet und außerdem gegeneinander versetzt. Die Mischflügel 34 übelappen sich. Die Mischflügel sind Platten, die axial und radial zur Antriebswelle verlaufen und eine Länge haben, die etwa doppelt so groß ist wie ihre radiale Höhe. Die Förderflügel 36 sind dagegen schmale Flacheisen, die ähnlich angeordnet sind wie die Förderpaddel 30. Sie sind also etwas um ihre eigene Längsachse verdreht angebracht.A metering screw 32, which is designed as a screw surface and has a pitch of 20 to 50 mm, in particular 35 mm, is arranged in an intermediate region 26.4 of the drive shaft which adjoins to the left. Mixing vanes 34 and conveyor vanes 36 are attached in an outer region 26.6 of the drive shaft. Both types of wings are arranged at mutual angular distances of 90 ° and are also offset from one another. The mixing blades 34 overlap. The mixing blades are plates that run axially and radially to the drive shaft and have a length that is approximately twice as large as their radial height. The conveying vanes 36, on the other hand, are narrow flat irons which are arranged similarly to the conveying paddles 30.

Das Ausgaberohr 22 hat einen Innenabschnitt 22.2, der am linken Ende der Bodenwanne 20 fest ansetzt und im Bereich zwischen zwei Stützen 4 endet. Hier setzt ein Außenabschnitt 22.4 des Ausgaberohrs an. An diesem Außenabschnitt 22.4 ist oben ein Wassereinlaß 50 mit Deckel vorgesehen, so daß dem trocken transportierten Schüttgut Wasser zugemischt werden kann. Der Außenabschnitt ist durch eine Steckverbindung mit dem Innenabschnitt 22.2 lösbar verbunden. Der Außenabschnitt kann also für den Transport abgenommen und später wieder eingesteckt und durch eine nicht dargestellte Verriegelung festgelegt werden. Für den Transport kann die sich ergebende Öffnung am Innenabschnitt 22.2 durch einen Deckel verschlossen werden.The dispensing tube 22 has an inner section 22.2, which attaches firmly to the left end of the floor pan 20 and ends in the area between two supports 4. This is where an outer section 22.4 of the dispensing tube comes into play. At this outer section 22.4, a water inlet 50 with a lid is provided at the top, so that water can be added to the dry bulk material. The outer section is detachably connected to the inner section 22.2 by a plug connection. The outer section can therefore be removed for transport and later reinserted and fixed by a locking mechanism, not shown. The resulting opening on the inner section 22.2 can be closed by a cover for transport.

An den beiden Trennstellen, links und rechts in Figur 1, ist die Antriebswelle 26 ebenfalls unterteilbar. Sie hat ebenfalls Steckverbindungen, insbesondere mit je einer Keilverzahnung, so daß beim Einstecken eine drehfeste Verbindung hergestellt wird.At the two separation points, left and right in Figure 1, the drive shaft 26 can also be divided. It also has plug connections, in particular with a spline each, so that a non-rotatable connection is made when inserted.

Der Behälter kann aus Stahl, Aluminium oder Kunststoff bestehen und hat, im Grundriß betrachtet, die Maße einer DIN-Europalette, nämlich 1200 mm x 800 mm, was seinen Transport erleichtert und verbilligt. An den vier Stützen 4 des Behälters sind unten Fußzapfen 38 angeordnet, die entweder als Füße dienen oder zum Aufsetzen des Behälters auf einen Stützbock nach Figur 3 und 4 dienen. Dieser Stützbock, der als Ganzes mit 40 bezeichnet ist, hat vier lotrechte Eckpfosten 42, die oben Aufnahmeöffnungen 43 für die Fußzapfen 38 des Behälters haben und unten Füße 44. Die Eckpfosten 42 sind untereinander durch Querstreben 44, 46, 48, z. B. in Gestalt von Vierkantrohren, verbunden.The container can be made of steel, aluminum or plastic and, viewed in plan, has the dimensions of a DIN Euro pallet, namely 1200 mm x 800 mm, which makes it easier and cheaper to transport. On the four supports 4 of the container foot 38 are arranged below, which either serve as feet or serve to place the container on a support frame according to FIGS. 3 and 4. This trestle, which is designated 40 as a whole, has four vertical corner posts 42, the top receiving openings 43 for the foot pin 38 of the container and bottom feet 44. The corner posts 42 are mutually by cross struts 44, 46, 48, z. B. connected in the form of square tubes.

Der Stützbock nach Figur 3 und 4 kann z. B. an einer Baustelle dann verwendet werden, wenn eine größere Ausgabehöhe für die gemischten Produkte erwünscht ist, also ein Freiraum unterhalb des Ausgabestutzens 24.The support frame according to Figures 3 and 4 can, for. B. can be used at a construction site when a larger dispensing height for the mixed products is desired, that is, a free space below the dispensing nozzle 24.

Der Stützbock 40 hat ebenfalls die Grundrißmaße einer DIN-Europalette. Beim Transport können auf den Querstreben 44 und 48 noch Baumaterialien und dgl. untergebracht werden, so daß der für den Stützbock erforderliche Raum noch zusätzlich genutzt werden kann. Für die Belieferung einer Baustelle können hier Gerüstteile, Bretter, Bohlen und Hilfswerkzeuge für die Handwerker befördert werden.The support frame 40 also has the outline dimensions of a DIN Euro pallet. During transport, building materials and the like can still be accommodated on the cross struts 44 and 48, so that the space required for the support frame can be used additionally. Scaffolding parts, boards, planks and auxiliary tools for the craftsmen can be transported here to supply a construction site.

An der Schrägwand 15 ist außen ein motorisch antreibbarer Rüttler 54 abnehmbar angebracht. Für den Transport läßt sich auch der Rüttler zur Gewichtsersparnis abbauen. Er ist über nicht dargestellte Leitungen elektrisch antreibbar und dient dazu, das Schüttgut in die Bodenwanne 20 zu befördern.On the inclined wall 15, a motor-driven vibrator 54 is removably attached on the outside. The vibrator can also be dismantled for transport to save weight. It can be driven electrically via lines (not shown) and serves to convey the bulk material into the floor pan 20.

Der Antriebsmotor 28 läßt sich vorzugsweise mit 220 Volt (16 A) betreiben, so daß er an normale Steckdosen anschließbar ist.The drive motor 28 can preferably be operated with 220 volts (16 A), so that it can be connected to normal sockets.

Die in dem Transportbehälter beförderten Schüttgüter können z. B. an einer Baustelle, insbesondere unter Zusatz von Wasser, gemischt werden zu Fertigmörtel, Putz, Beton, Gips, wobei die Dosierschnecke unter dem Einfluß einer hier nicht dargestellten Steuervorrichtung dafür sorgen kann, daß eine ganz bestimmte Menge Schüttgut pro Zeiteinheit gefördert wird, entsprechend z. B. einer ganz bestimmten Menge von Wasser, das in den Wassereinlaß 15 fließt, so daß sich die gewünschte Konsistenz des nassen Mischgutes ergibt. Es kann meist auf die Verwendung einer weiteren Mischvorrichtung an Ort und Stelle, z. B. einer Baustelle, verzichtet werden.The bulk goods transported in the transport container can e.g. B. at a construction site, in particular with the addition of water, mixed to ready mortar, plaster, concrete, plaster, the metering screw under the influence of a control device, not shown here, can ensure that a very specific amount of bulk material is conveyed per unit of time accordingly e.g. B. a very specific amount of water flowing into the water inlet 15, so that the desired consistency of the wet mix results. It can usually be due to the use of another mixing device on the spot, e.g. B. a construction site.

Entsprechendes gilt z. B. für die Lieferung von Getreide oder Mehl an eine Bäckerei. Auch dort kann an Ort und Stelle Wasser zugemischt werden.The same applies to z. B. for the delivery of grain or flour to a bakery. Water can also be mixed in there.

Das Gewicht und die Maße des Transportbehälters wurden denen der DIN-Europaletten angepaßt, so daß keine Probleme bei der Verwendung von Staplern in der Industrie, bei der Spedition und beim Handel entstehen, und daß auch Handwerker keine Ladungsprobleme haben. Der Transportbehälteer einschließlich der an ihm verbleibenden Bestandteile, nämlich Fördervorrichtung innerhalb der Bodenwanne und Dosierschnecke, hat, je nach Größe, ein Leergewicht zwischen 90 Kg und 2 Tonnen.The weight and dimensions of the transport container have been adapted to those of the DIN Euro pallets, so that there are no problems with the use of forklifts in industry, for forwarding and trading, and that craftsmen also have no loading problems. Depending on its size, the transport container, including the components remaining on it, namely the conveyor device inside the floor pan and the dosing screw, has an empty weight of between 90 kg and 2 tons.
