Description

Die Erfindung bezieht sich auf eine stationäre Abfallpresseneinheit zur Verbindung mit einem mobilen Wechselcontainer mit den Merkmalen des Oberbegriffs des Anspruchs 1.The invention relates to a stationary waste compactor unit for connection to a mobile interchangeable container with the features of the preamble of claim 1.

Es sind Abfallcontainer mit integrierter Abfallpresse bekannt, um den in einen Aufgabetrichter des Containers geworfenen Abfall zu komprimieren und damit das Ladevolumen des Containers besser ausnutzen zu können. Dies gilt insbesondere für großvolumige Abfälle wie Kartonagen. Bei mobilen Wechselcontainern wird jedoch für die Anordnung der Presseneinheit und ihres Antriebs ein nicht unerheblicher Teil des zur Verfügung stehenden Containervolumens benötigt, so dass es unwirtschaftlich ist, die Presseneinheit mit dem Antrieb als festen Teil des Containers auszubilden, der stets mittransportiert werden muss.Waste containers with an integrated waste press are known in order to compress the waste thrown into a hopper of the container and thus to be able to make better use of the loading volume of the container. This applies in particular to large-volume waste such as cardboard boxes. In the case of mobile interchangeable containers, however, a not inconsiderable part of the available container volume is required for the arrangement of the press unit and its drive, so that it is uneconomical to form the press unit with the drive as a fixed part of the container, which must always be transported.

Immer dann, wenn regelmäßig große Mengen von komprimierbarem Abfall anfallen, werden daher stationäre Abfallpressen eingesetzt, die mit einem mobilen Wechselcontainer koppelbar sind. Die am Aufgabetrichter der stationären Abfallpresseneinheit aufgegebenen Abfallmenge wird am Boden von einem Pressstempel ins Innere des Wechselcontainers geschoben. Die eigentliche Nachverdichtung findet erst dann statt, wenn das Containervolumen bereits mit unverdichtetem Abfall gefüllt ist. Ist mit zunehmender Füllung eine weitere Nachverdichtung nicht mehr möglich, wird die Zuführöffnung des Wechselcontainers, in welche hinein der Pressstempel der stationären Presseneinheit wirkt, verschlossen, und der Wechselcontainer kann abgefahren werden. Anschließend wird ein anderer, leerer Wechselcontainer vor der stationären Presseneinheit positioniert. Die Presseneinheit ragt mit ihrem Bodenblech durch die Zuführöffnung etwas bis ins Innere des Wechselcontainers, sodass auch der Presskolben bis in den Anfang des Innenraums des Containers geschoben werden kann. Durch den überlappenden Boden wird zudem die Trennfuge überdeckt, und es wird so vermieden, dass Abfall zwischen die Presseneinheit und den davor aufgestellten Wechselcontainergerät.Whenever large amounts of compressible waste are generated on a regular basis, stationary waste presses that can be coupled to a mobile interchangeable container are used. The amount of waste fed into the feed hopper of the stationary waste press unit is discharged at the bottom of pushed into the interior of the interchangeable container using a press ram. The actual post-compaction only takes place when the container volume is already filled with uncompacted waste. If further post-compaction is no longer possible with increasing filling, the feed opening of the interchangeable container, into which the press ram of the stationary press unit acts, is closed and the interchangeable container can be removed. Another, empty interchangeable container is then positioned in front of the stationary press unit. The bottom plate of the press unit protrudes slightly through the feed opening into the interior of the interchangeable container, so that the press piston can also be pushed into the beginning of the interior of the container. The overlapping floor also covers the parting line, and waste is thus avoided between the press unit and the interchangeable container device set up in front of it.

Eine gattungsgemäße Abfallpresseneinheit zeigt EP 472 870 A1 . Der Presskolben ist hierbei zweiteilig ausgebildet und besitzt einen unteren Pressschild, der fest mit einer Vorschubeinheit verbunden ist, sowie einen beweglichen Presskolben, der im rückwärtigen Bereich des Pressschildes beweglich angebunden ist und mit einer gekrümmten Rückwand am Aufgabetrichter zusammenwirkt. Beim Rückzug des Presskolbens schabt der bewegliche Teil über den Boden und schiebt sich unter eventuelle Abfallreste, die auf dem Boden liegen geblieben sind, oder unter Abfallteile, die vom Benutzer während der bereits begonnenen Vorschubbewegung des Presskolbens in den Trichter aufgegeben wurden. Erreicht der bewegliche Teil die gebogene Rückwand, so folgt er deren Kontur und klappt hoch, sodass die auf dem beweglichen Teil aufliegenden Abfallreste vor den angeordneten Pressschild abgeworfen werden.A generic waste press unit shows EP 472 870 A1 . The plunger is designed in two parts and has a lower press plate, which is firmly connected to a feed unit, and a movable plunger, which is movably connected in the rear area of the press plate and interacts with a curved rear wall on the feed hopper. When the plunger retracts, the moving part scrapes the ground and moves under any debris that may have been left on the ground or under debris that the user has placed in the hopper while the plunger advances. When the moving part reaches the curved rear wall, it follows its contour and folds up so that the waste resting on the moving part is ejected in front of the press shield.

Um einen ausreichend großen Aufgabetrichter zu schaffen, mit dem eine bequeme Aufgabe des zu entsorgenden Abfalls möglich ist und in dem auch die Funktion des beweglichen Pressschilds gewährleistet ist, muss ein entsprechend großer axialer Hub vorgesehen sein. Dieser führt zu einer entsprechend großen axialen Baulänge der Abfallpresseneinheit, da die Ausfahrlänge der Hydraulikzylinder, die als einziges Antriebsmittel im rauen Arbeitsumfeld geeignet sind, die hohen Kräfte zum Pressen von Abfall aufzubringen, meist weniger als die Hälfte der Kolbenlänge beträgt, oft sogar nur 40 % der Kolbenlänge.A corresponding large axial stroke can be provided. This leads to a correspondingly large axial overall length of the waste compactor unit, since the extension length of the hydraulic cylinders, which are the only drive means in the harsh working environment suitable for applying the high forces for pressing waste, is usually less than half the piston length, often even just 40% the piston length.

Ein weiteres Problem besteht darin, dass ein Verkanten des Pressschildes beim Pressvorgang vermieden werden muss. Aus dem Stand der Technik sind dazu kreuzförmige Antriebsanordnungen bekannt, bei denen zwei Hydraulikzylinder über Kreuz angeordnet sind, sodass auf beide Seiten des Schildes stets die gleiche Kraft ausgeübt wird, wenn die Ölkreisläufe der Hydraulikzylinder miteinander verbunden sind.A further problem is that tilting of the press plate during the pressing process must be avoided. For this purpose, cross-shaped drive arrangements are known from the prior art, in which two hydraulic cylinders are arranged crosswise, so that the same force is always exerted on both sides of the blade when the oil circuits of the hydraulic cylinders are connected to one another.

Aus der FR 2 979 073 A1 ist eine stationäre Abfallpresse zur Verbindung mit einem Wechselcontainer bekannt, bei der eine deutliche Reduzierung der axialen Länge erreicht wird, sodass es insbesondere möglich ist, Abfall von der Stirnseite an der Rückseite her aufzugeben. Der Benutzer muss nicht mehr seitlich an die Abfallpresse herantreten, um in den Aufgabetrichter abwerfen zu können. Die stationäre Presseneinheit kann damit platzsparend aufgestellt werden, zum Beispiel an einer Laderampe. Die Reduzierung der axialen Länge wird dadurch erreicht, dass mehrere Hydraulikzylinder mit ihren jeweiligen Zylinderelementen mechanisch fest verbunden sind und deren Kolbenstangen in entgegengesetzte Richtungen ausfahren. Die Einheit aus den miteinander verbundenen Zylindern ist freischwebend gelagert, während sich die Kolbenstangen an den Lagern an der Rückwand des Gehäuses beziehungsweise am Pressschild abstützen. Um der zweiten oben genannte Problematik zu begegnen, nämlich ein Verkanten des Pressschildes bei der Vorschubbewegung zu verhindern, ist eine Multizylindereinheit vorgesehen. Hierbei handelt es sich um eine spiegelsymmetrische Anordnung aus einem zentralen Hydraulikzylinder und zwei Nebenhydraulikzylindern vorgesehen. Der zentrale Hydraulikzylinder stützt sich an der Rückseite des Gehäuses der Presseneinheit ab, während die beidseits des zentralen Hydraulikzylinders angeordneten Nebenzylinder mit dem Pressschild verbunden sind. Durch diese spiegelsymmetrische Anordnung mit zwei Nebenzylindern, die den Pressschild führen und zwischen denen eine gewissen Abstützbreite besteht, soll ein Verkanten vermieden werden. In der Praxis hat sich jedoch gezeigt, dass die Distanz zwischen den beiden Lagern an den Nebenzylindern in Relation zur Breite des Pressschildes nicht ausreichend ist, um das Verkanten wirksam zu unterbinden. Ein weiterer Nachteil besteht darin, dass kein beweglicher Pressekolben mehr zur Reinigung des Bodens einsetzbar ist, da der rückwärtige Bauraum hinter dem Pressschild für die Anordnung und Bewegung der Multizylindereinheit benötigt wird.From the FR 2 979 073 A1 a stationary waste compactor for connection to an interchangeable container is known, in which a clear reduction in the axial length is achieved, so that it is possible in particular to feed waste from the front side to the rear. The user no longer has to approach the waste press from the side to be able to discharge into the feed hopper. The stationary press unit can thus be set up to save space, for example on a loading ramp. The reduction in the axial length is achieved in that several hydraulic cylinders are mechanically fixed to their respective cylinder elements and their piston rods extend in opposite directions. The unit consisting of the interconnected cylinders is mounted in a freely suspended manner, while the piston rods are supported on the bearings on the rear wall of the housing or on the press shield. In order to counteract the second problem mentioned above, namely to prevent the pressing plate from tilting during the feed movement, a multi-cylinder unit is provided. This is a mirror-symmetrical arrangement of a central hydraulic cylinder and two secondary hydraulic cylinders. The central one The hydraulic cylinder is supported on the rear of the press unit housing, while the secondary cylinders, which are arranged on both sides of the central hydraulic cylinder, are connected to the press plate. This mirror-symmetrical arrangement with two auxiliary cylinders, which guide the pressing plate and between which there is a certain support width, should prevent tilting. In practice, however, it has been shown that the distance between the two bearings on the secondary cylinders in relation to the width of the press plate is not sufficient to effectively prevent tilting. A further disadvantage is that a movable press piston can no longer be used to clean the floor, since the rear installation space behind the press shield is required for the arrangement and movement of the multi-cylinder unit.

Die in DE 10 2005 054 986 B3 beschriebene Abfallpresseneinheit sieht Führungseinrichtungen vor, die sich nicht nur über die Länge des Aufgabetrichters erstrecken, sondern darüber hinaus bis in den als Abfallbehälter angesetzten Wechselcontainer. Ebenso wie die Führungseinrichtungen sind die Hubzylinder entsprechend lang ausgestaltet und ragen in den Container hinein. Daher sind Teile des Abfallbehältervolumens nicht vollständig nutzbar.In the DE 10 2005 054 986 B3 The waste press unit described provides guide devices that not only extend over the length of the feed hopper, but also into the interchangeable container that is used as a waste container. Like the guide devices, the lifting cylinders are designed to be correspondingly long and protrude into the container. Therefore, parts of the waste container volume are not fully usable.

DE162781 0A1 beschreibt eine Abfallpresseneinheit laut dem Oberbegriff des Anspruchs 1, mehr insbesondere eine Abfallpresseneinheit mit einer Antriebseinheit, die dadurch verkürzt ist, dass zwei Zylindergehäuse von Hydraulikzylindern miteinander gekoppelt sind. Es ist einzelne Antriebseinheit vorgesehen, die zentral angeordnet ist, wodurch der Aufgaberaum nicht vollständig nutzbar ist, weil die überstrichene Fläche durch diese Antriebsanordnung limitiert ist. DE1627810A1 describes a refuse compactor unit according to the preamble of claim 1, more particularly a refuse compactor unit with a drive unit which is shortened in that two cylinder housings of hydraulic cylinders are coupled to one another. A single drive unit is provided which is centrally located whereby the loading space is not fully usable as the swept area is limited by this drive arrangement.

Der Pressschild selbst ist formschlüssig geführt, aber nicht die Antriebseinheit.The press shield itself is guided in a form-fitting manner, but not the drive unit.

Die Aufgabe der vorliegenden Erfindung liegt somit darin, bei reduzierter axialer Baulänge der stationären Presseneinheit für einen mobilen Wechselcontainer eine gleichmäßige und verkantungsfreie Führung des Pressschildes zu ermöglichen.The object of the present invention is therefore to enable the pressing plate to be guided evenly and without tilting with a reduced axial overall length of the stationary press unit for a mobile interchangeable container.

Diese Aufgabe wird durch eine stationäre Abfallpresseneinheit mit den Merkmalen des Anspruchs 1 gelöst.This object is achieved by a stationary waste compactor unit having the features of claim 1.

"Stationär" bedeutet im Sinne der vorliegenden Erfindung, dass keine feste konstruktive Verbindung mit dem Wechselcontainer besteht; jedoch sind temporäre, lösbare Verbindungen zum Wechselcontainer während des Pressenbetriebs möglich. Eine ortsfeste Aufstellung ist damit ebenso möglich wie die feste Anbringung auf einer mobilen Plattform.In the context of the present invention, "stationary" means that there is no fixed structural connection to the interchangeable container; however, temporary, detachable connections to the interchangeable container are possible while the press is in operation. Stationary installation is just as possible as fixed attachment to a mobile platform.

Zur Orientierung ist im Sinne der vorliegenden Erfindung die vordere Seite im Folgenden diejenige Stirnseite, die dem mobilen Wechselcontainer zuzuwenden ist und an der der vom Pressschild ergriffene Müll ausgeschoben wird. Die hintere oder rückwärtige Seite befindet sich an der gegenüberliegenden Stirnseite an dem insbesondere rechteckig ausgebildeten Grundrahmen, auf dem die Abfallpresseneinheit aufgebaut ist.For orientation in the sense of the present invention, the front side is in the following that front side which is to be turned towards the mobile interchangeable container and on which the refuse seized by the press plate is ejected. The rear or rear side is located on the opposite end face on the base frame, which is in particular rectangular in shape, on which the waste compactor unit is built.

Die Erfindung sieht zwei Multizylindereinheiten vor, die vollständig außerhalb des von dem Presskolben überstrichenen Flächenbereichs angeordnet sind, sodass der Einsatz des bewährten zweiteiligen Klapp-Presskolbens weiterhin möglich ist. Die Multizylindereinheiten mit ihren zu entgegengesetzten Seiten wirkenden Kolbenstangen führen zu einer Halbierung der axialen Baulänge gegenüber herkömmlichen Abfallpresseneinheiten.The invention provides two multi-cylinder units, which are arranged completely outside the surface area swept by the plunger, so that the use of the proven two-part folding plunger is still possible. The multi-cylinder units with their towards opposite sides acting piston rods lead to a halving of the axial length compared to conventional waste compactor units.

Gegenüber den bekannten Abfallpressen besteht der Vorteil bei der Erfindung außerdem darin, dass die Kräfte, die durch die Multizylindereinheiten ausgeübt werden, jeweils ganz außen am Pressschild ansetzen und dass der Pressschild mit seiner gesamten Arbeitsbreite zwischen den Wirkungslinien der außen angeordneten Multizylindereinheiten angeordnet ist. Durch die seitliche Anordnung können die Antriebe nahezu vollständig vom Abfallaufgaberaum abgeschirmt werden. Die Arbeitsbreite ist derjenige Teil der Bodenfläche, der durch die Seitenwände begrenzt ist und auf dem Abfall verschoben und komprimiert werden können.Compared to the known waste presses, the advantage of the invention is that the forces exerted by the multi-cylinder units start on the very outside of the press plate and that the press plate is arranged with its entire working width between the lines of action of the multi-cylinder units arranged on the outside. Due to the lateral arrangement, the drives can be almost completely shielded from the waste feed area. The working width is that part of the floor area bounded by the side walls on which waste can be pushed and compressed.

Vorzugsweise ragt lediglich eine seitlich direkt an den Pressschild angebundene Lagerkonsole durch eine Schlitzausnehmung in der inneren Seitenwand des Aufgabetrichters, während das Lager an der Lagerkonsole, an dem die Multizylindereinheit angebunden ist, bereits durch die innere Seitenwand am Aufgabetrichter abgeschirmt ist.Preferably, only one bearing bracket directly connected laterally to the press shield protrudes through a slotted recess in the inner side wall of the feed hopper, while the bearing on the bearing bracket to which the multi-cylinder unit is attached is already shielded by the inner side wall of the feed hopper.

Vorzugsweise ist auch noch eine äußere Seitenwand vorgesehen, um zu verhindern, dass Benutzer von außen in den Antrieb eingreifen können, und/oder um den Antrieb vor Witterungseinflüssen zu schützen. Die Multizylindereinheiten bewegen sich dann in einem Zwischenraum zwischen der äußeren Seitenwand und der inneren Seitenwand des Aufgabetrichters.An outer side wall is preferably also provided in order to prevent users from being able to reach into the drive from the outside and/or to protect the drive from the effects of the weather. The multi-cylinder units then move in a space between the outer side wall and the inner side wall of the hopper.

Um zu erreichen, dass der Pressschild dicht über den Bodenbereich des Aufgabetrichters geführt wird und sich nicht auf dort liegenden Abfall aufschieben und aufsteigen kann, ist erfindungsgemäß zusätzlich vorgesehen, dass die Lagerkonsole des Pressschilds zumindest im Bereich der Lagerstelle und/ oder die Basiseinheit der Multizylindereinheit mit den beiden miteinander gekoppelten Zylindern jeweils in Schienen geführt sind oder entlang von Gleitschienen geführt sind. Die Gleitschienen sind außen am Aufgabetrichter angeordnet, vorzugsweise in dem genannten Zwischenraum zwischen der inneren und der äußeren Seitenwand. Dabei ist insbesondere vorgesehen, die Lagerstelle und/oder die Basiseinheit mit Gleitplatten zu versehen, die nach oben und nach unten weisend angeordnet sind. Durch die seitlichen Führungen werden entsprechende Gleitflächen bereitgestellt, an denen die Teile entlang gleiten können, falls es zu einem Hochsteigen des Pressschildes kommen sollte. Ansonsten können die Gleitelemente berührungsfrei durch die Schienen laufen. Möglich ist auch, den Pressschild bewusst in den Seitenführungen hängend zu verfahren, sodass vermieden wird, dass der Pressschild unmittelbar über den Boden schabt.In order to ensure that the pressing plate is guided tightly over the bottom area of the feed hopper and cannot push up and rise onto the waste lying there, it is additionally provided according to the invention that the bearing bracket of the pressing plate, at least in the area of the bearing point and/or the base unit of the multi-cylinder unit the two coupled cylinders are each guided in rails or are guided along slide rails. The slide rails are arranged on the outside of the feed hopper, preferably in said space between the inner and outer side walls. In particular, it is provided that the bearing point and/or the base unit be provided with sliding plates which are arranged pointing upwards and downwards. The lateral guides provide corresponding sliding surfaces along which the parts can slide if the pressing plate should rise. Otherwise, the sliding elements can run through the rails without touching them. It is also possible to deliberately move the press shield hanging in the side guides, so that the press shield is prevented from scraping directly over the ground.

Weiterhin vorzugsweise sieht die erfindungsgemäße Abfallpresseneinheit vor, dass an den Endpunkten der Kolbenstangen die Lagerachsen jeweils so ausgerichtet sind, dass sie zueinander senkrecht verlaufen. Beispielsweise kann die vordere Kolbenstange, die mit dem Pressschild verbunden ist, an einer vertikalen Achse mit der Lagerkonsole am Pressschild verbunden sein, während die rückwärtige Kolbenstange, die sich am Grundgestell abstützt, an einem Lager mit horizontaler Achse angebunden ist. Durch diese um 90° versetzte Anordnung der Achsen können alle im Betrieb auftretenden Schiefstellungen zwischen dem ortsfesten Gestell, der Multizylindereinheit und dem Pressschild ausgeglichen werden. Verspannungen werden wirksam vermieden und der rauen Arbeitsumgebung wird Rechnung getragen.Furthermore, the waste compactor unit according to the invention preferably provides that the bearing axes are aligned at the end points of the piston rods in such a way that they run perpendicular to one another. For example, the front piston rod, which is connected to the press plate, can be connected to the bearing bracket on the press plate on a vertical axis, while the rear piston rod, which is supported on the base frame, is connected to a bearing with a horizontal axis. This 90° offset arrangement of the axes means that any misalignments that occur during operation between the stationary frame, the multi-cylinder unit and the press plate can be compensated for. Tensions are effectively avoided and the rough working environment is taken into account.

Die Erfindung wird nachfolgend mit Bezug auf die Zeichnungen näher erläutert. Die Figuren zeigen jeweils in geschnittener perspektivischer Ansicht:

Figur 1 zeigt eine stationäre Abfallpresseneinheit 100 mit einem mobilen Wechselcontainer 200. figure 1 shows a stationary waste compactor unit 100 with a mobile interchangeable container 200.

Der Wechselcontainer 200 umfasst einen geschlossenen Boden 201, Seitenwände 202, eine Rückwand 203 und ein Dach 204. Eine vordere Wand 205 verschließt nur den oberen Teil der Höhe des Wechselcontainers 200, während darunter eine Zuführöffnung 206 frei bleibt, die sich nahezu über die gesamte Breite des Innenraums erstreckt.The interchangeable container 200 includes a closed floor 201, side walls 202, a rear wall 203 and a roof 204. A front wall 205 closes only the upper part of the height of the interchangeable container 200, while underneath a feed opening 206 remains free, which extends almost over the entire width of the interior extends.

Die Abfallpresseneinheit 100 umfasst zumindest:

  • einen auf einem Grundrahmen 109 aufliegenden, ebenen Boden 101,
  • einen Aufgabetrichter 102 mit Seitenwänden 103 und einer gebogenen Rückwand 105 und
  • einen rückwärtigen Stützrahmen 107.
The garbage compactor unit 100 comprises at least:
  • a level floor 101 resting on a base frame 109,
  • a hopper 102 with side walls 103 and a curved rear wall 105 and
  • a rear support frame 107.

In den Seitenwänden 103 des Aufgabetrichters 102 ist jeweils eine Schlitzausnehmung 104 eingebracht. Dahinter befindet sich eine Führungsschiene 150. Innerhalb des Aufgabetrichters 102 ist ein Pressschild 130 mit einer Schaufel 131 angeordnet. In der in Figur 1 dargestellten Stellung des Pressschildes 130 ist die Schaufel 131, bedingt durch die gebogene Form der Rückwand 105, nach oben geschwenkt, sodass eventuell darauf aufliegender Abfall zurück auf den Boden 101 geworfen wird. Zwischen dem vertikalen Stützrahmen 107 an der Rückseite des Grundrahmens 109 und dem Pressschild 130 ist eine Multizylindereinheit 110 mit zwei Hydraulikzylindern angeordnet, die den Vorschub des Pressschildes 130 bewirken. Auf der anderen, rechten Seite ist ebenfalls eine solche Multizylindereinheit vorgesehen, die jedoch aus Gründen der Übersichtlichkeit hier und in den folgenden Figuren nicht dargestellt ist. Ebenfalls nicht dargestellt sind die Ölleitungen, die mit einer Schleppkette zur Basisgruppe des Antriebs mit den beiden verbundenen Hydraulikzylindern geführt sind.In the side walls 103 of the feed hopper 102 a slot recess 104 is introduced. A guide rail 150 is located behind it. in the in figure 1 In the illustrated position of the pressing plate 130, the blade 131 is pivoted upwards due to the curved shape of the rear wall 105, so that any waste lying on it is thrown back onto the ground 101. A multi-cylinder unit 110 with two hydraulic cylinders is arranged between the vertical support frame 107 on the back of the base frame 109 and the press plate 130, which cause the press plate 130 to advance. Such a multi-cylinder unit is also provided on the other, right-hand side, but this is not shown here or in the following figures for reasons of clarity. Also not shown are the oil lines, which are routed with a drag chain to the base group of the drive with the two connected hydraulic cylinders.

Figur 2 zeigt die Abfallpresseneinheit 100 aus der gleichen Perspektive in vergrößerter Ansicht und ohne den Wechselcontainer 200. Im Bereich der Seitenwand 103 des Aufgabetrichters 102 ist hier insbesondere die Führungsschiene 150 sichtbar, die hinter der Schlitzausnehmung 104 angeordnet ist. Oberhalb davon sind Gleitflächen 151,152 ausgebildet, die rechtwinklig zur vertikalen Seitenwand angeordnet sind. figure 2 shows the waste compactor unit 100 from the same perspective in an enlarged view and without the interchangeable container 200. In the area of the side wall 103 of the feed hopper 102, the guide rail 150, which is arranged behind the slotted recess 104, is particularly visible here. Sliding surfaces 151, 152 are formed above this, which are arranged at right angles to the vertical side wall.

Im vorderen Bereich sind die Einzelteile der Multizylindereinheit 110 erkennbar. Die beiden Zylindergehäuse 111.1, 112.1 sind fest miteinander verbunden. Sie besitzen nach oben und nach unten weisende Gleitelemente 113, 114. Der untere Hydraulikzylinder 111 ist an einem Lager 106 mit einer horizontalen Lagerachse schwenkbeweglich mit dem Stützrahmen 107 verbunden. Der obere Hydraulikzylinder 112 ist schwenkbeweglich über ein vertikales Lager 121 mit einer Lagerkonsole 120 verbunden, die seitlich über den Pressschild 130 hinausragt. Dadurch, dass die Achsen der Lager 121, 106 um 90° versetzt zueinander ausgerichtet sind, ist die Multizylindereinheit 110 in zwei räumlichen Orientierungen gelenkig gelagert, so dass Schiefstellungen und daraus resultierende Spannungen vermieden werden.The individual parts of the multi-cylinder unit 110 can be seen in the front area. The two cylinder housings 111.1, 112.1 are firmly connected to one another. They have sliding elements 113, 114 pointing upwards and downwards. The lower hydraulic cylinder 111 is pivotably connected to the support frame 107 at a bearing 106 with a horizontal bearing axis. The upper hydraulic cylinder 112 is pivotably connected via a vertical bearing 121 to a bearing bracket 120 which projects laterally beyond the press plate 130 . Due to the fact that the axes of the bearings 121, 106 are aligned offset by 90° to one another, the multi-cylinder unit 110 is articulated in two spatial orientations, so that misalignments and the resulting stresses are avoided.

Die Lagerkonsole 120 ist, wie die Multizylindereinheit 110 auch, mit nach oben und nach unten weisenden Gleitelementen 123 belegt. Das Paket aus Lagerkonsole 120 und Gleitelementen 123 wird in der Führungsschiene 150 geführt, während die Basisgruppe der Multizylindereinheit 110, die die beiden Zylindergehäuse 111, 112 umfasst, über die Gleitplatten 113, 114 zwischen den übereinander angeordneten Gleitschienen 151, 152 geführt ist.The bearing bracket 120, like the multi-cylinder unit 110, is covered with sliding elements 123 pointing upwards and downwards. The package of bearing bracket 120 and sliding elements 123 is guided in the guide rail 150, while the base group of the multi-cylinder unit 110, which includes the two cylinder housings 111, 112, is guided via the sliding plates 113, 114 between the sliding rails 151, 152 arranged one above the other.

Figur 3 zeigt die stationäre Abfallpresseneinheit 100 wiederum aus der gleichen Perspektive wie in Fig. 2, dieses Mal jedoch mit vorgeschobenem Pressschild 130. Die bewegliche Schaufel 131 liegt auf dem Boden 101 auf. Diese besitzt eine spitzwinklige Schaberkante 132, die beim Rückhub des Pressschilds 130 den Abfall auf dem Boden 101 untergreift. Am Ende eines Rückhubs klappt die Schaufel 131 mit der spitzwinkligen Schaberkante 132 nach oben, so dass der von der Schaufel untergriffene Abfall vor den Pressschild 130 gefördert wird. figure 3 shows the stationary waste compactor unit 100 again from the same perspective as in FIG 2 , but this time with the pressing plate 130 advanced. This has an acute-angled scraper edge 132 which reaches under the waste on the floor 101 during the return stroke of the pressing plate 130 . At the end of a return stroke, the shovel 131 folds with the acute-angled scraper edge 132 upwards, so that the waste that the shovel reaches under is conveyed in front of the press shield 130 .

Die Multizylindereinheit 110 ist vollständig ausgefahren, sodass ihre Kolbenstangen 111.2, 112.2 außerhalb der Zylindergehäuse 111.1, 112.1 sichtbar sind. Durch die Schlitzausnehmung 104 in der Seitenwand 103 des Aufgabetrichters 102 ist erkennbar, dass sich die Führungsschiene 150 nur so weit nach hinten hin erstreckt, wie es für die Führung der Lagerkonsole 21 bis zum hintersten Rückzugspunkt des Pressschilds 130 erforderlich ist. Die Führungsschiene 150 endet daher in einem mittleren Bereich der Länge des Aufgabetrichters 102, um auch die Bewegungen der Basisgruppe mit den beiden Zylindergehäusen 112.1, 111.1 der Multizylindereinheit 110 nicht zu behindern.The multi-cylinder unit 110 is fully extended so that its piston rods 111.2, 112.2 are visible outside of the cylinder housing 111.1, 112.1. The slotted recess 104 in the side wall 103 of the feed hopper 102 shows that the guide rail 150 only extends backwards as far as is necessary to guide the bearing bracket 21 to the rearmost retraction point of the press plate 130 . The guide rail 150 therefore ends in a middle area of the length of the feed hopper 102, so as not to impede the movements of the base group with the two cylinder housings 112.1, 111.1 of the multi-cylinder unit 110.

In Figur 4 ist dieselbe Situation der stationären Abfallpresseneinheit 100 wie in Figur 3 gezeigt, jedoch mit Teilen des daran angesetzten mobilen Wechselcontainers 200 und mehr mit Blick von vorn, und zwar auf die Öffnung 206 in der Vorderwand 205 und die Vorderseite des Pressschilds 130.In figure 4 is the same situation of the stationary waste compactor unit 100 as in figure 3 shown, but with parts of the mobile interchangeable container 200 attached to it and more with a view from the front, namely of the opening 206 in the front wall 205 and the front of the press plate 130.

Der Pressschild 130 befindet sich in der vordersten Stellung, in der er geringfügig in die Zuführöffnung 205 im Wechselcontainer 200 hineinragt. Aus dieser Ansicht wird im Bereich der rechten Seitenwand der Abfallpresseneinheit 100 insbesondere die Anordnung der Gleitschienen deutlich:

  • Die Gleitschiene 151 befindet sich in dem Paket von Gleitschienen oben und ist nach unten weisend ausgerichtet. Sie dient als Anlage für die oberen Gleitelemente 114 an der Multizylindereinheit 110.
  • Die untere Gleitschiene 152 ist nach oben weisend ausgerichtet und dient als Anlage für die unteren Gleitelemente 113 an der Multizylindereinheit 110.
  • Zwischen den Gleitschienen 151, 152 befindet sich eine Führungsschiene 150, die als U-förmiges Profil ausgebildet ist, welches sich zur Schlitzausnehmung 104 hin öffnet. In der Führungsschiene 150 wird die Lagerkonsole 120 mit dem Lager 121 und dem Gelenkkopf der Kolbenstange 111.1 des oberen Hydraulikzylinders geführt.
The pressing shield 130 is in the foremost position in which it protrudes slightly into the feed opening 205 in the interchangeable container 200 . From this view, the arrangement of the slide rails in the area of the right side wall of the waste compactor unit 100 is particularly clear:
  • Slide rail 151 is at the top of the pack of slide rails and is oriented downward. It serves as a support for the upper sliding elements 114 on the multi-cylinder unit 110.
  • The lower sliding rail 152 is aligned upwards and serves as a support for the lower sliding elements 113 on the multi-cylinder unit 110.
  • Between the slide rails 151, 152 there is a guide rail 150 which is designed as a U-shaped profile which extends to the slot recess 104 opens towards. The bearing bracket 120 with the bearing 121 and the articulated head of the piston rod 111.1 of the upper hydraulic cylinder is guided in the guide rail 150.
