Description

Die Erfindung betrifft einen Deckelöffner für Großbehälter mit Deckelzapfen aufweisendem Schiebedeckel, der im Bereich der Einschüttöffnung eines Sammelbehälters eines Müllfahrzeugs angeordnet ist, mit einer schwenkbaren Einrichtung zum Erfassen der Deckelzapfen, an der eine Antriebseinrichtung zum Bewegen der schwenkbaren Einrichtung in Ruhe- und Arbeitsstellung angreift.The invention relates to a lid opener for large containers with a lid pin having a sliding lid, which is arranged in the region of the pouring opening of a collecting container of a refuse collection vehicle, with a pivotable device for detecting the lid pin, on which a drive device for moving the pivotable device acts in the rest and working position.

Derartige Deckelöffner sind meist an Müllfahrzeugen, die eine offene Einfüllwanne, wie z.B. bei einem Sperrmüllfahrzeug, aufweisen, oder an einem Fahrzeug für die Entleerung von Großbehältern von 2,5 bis 10 m3 angeordnet.Such lid openers are usually arranged on garbage trucks that have an open fill tray, such as a bulky refuse truck, or on a vehicle for emptying large containers of 2.5 to 10 m 3 .

Die Behälter mit einem Fassungsvolumen von ca. 0,6 bis 1 m 3 haben einen Schiebedeckel, der an seitlichen Schwenkarmen etwa zentral an der Behälterseitenwand gelagert ist und beim Öffnen einen kreisbogenförmigen Öffnungsweg zurücklegt. Die Öffnungsbewegung wird dem Behälterdeckel in bekannter Weise dadurch aufgezwungen, daß ein Deckelöffner an seitlichen Zapfen des Behälterdeckels als Widerlager bei der Entleerung des Behälters angreift und der Deckel dadurch eine der Entleerungsrichtung entgegengesetzte Bewegung ausführt. Der Deckelöffner hat gleichzeitig die Aufgabe, ein Überkippen des Behälters in die Einfüllöffnung zu verhindern.The containers with a capacity of approx. 0.6 to 1 m 3 have a sliding lid, which is mounted on the side swivel arms approximately centrally on the side wall of the container and covers an arcuate opening path when opened. The opening movement is forced on the container lid in a known manner in that a lid opener acts on the lateral pins of the container lid as an abutment during the emptying of the container and the lid thereby executes a movement opposite to the emptying direction. The lid opener also has the task of preventing the container from tipping over into the filling opening.

Die bekannten Deckelöffner dieser Art sind entweder pendelnd in der Einschüttöffnung des Sammelbehälters angeordnet oder als Auflaufkurve für die Deckelzapfen an den Seitenwänden der Einschüttöffnung ausgebildet. Vorbedingung für die Anwendung dieser bekannten Deckelöffner ist, daß die Breite der Einfüllöffnung in etwa der Breite des zu entleerenden Müllbehälters entspricht.The known lid openers of this type are either arranged in a swinging manner in the pouring opening of the collecting container or are designed as a run-up curve for the lid pins on the side walls of the pouring opening. A precondition for the use of these known lid openers is that the width of the filling opening corresponds approximately to the width of the waste container to be emptied.

Bei der Entleerung von Großbehältern von ca. 2,5 m3 und größer, ist die Einschüttöffnung erheblich breiter, so daß dann, wenn mit diesem Fahrzeug auch kleinere Behälter entleert werden sollen, besondere Maßnahmen zur Anbringung eines Deckelöffners getroffen werden müssen. Der Deckelöffner wird in diesem Fall so in der Einschüttöffnung angebracht, daß er bei der Entleerung von kleineren Behältern mit Schiebedeckel in die Einschüttöffnung ausklappbar oder schwenkbar ist. Bei der Entleerung von Großbehältern wird der Deckelöffner eingeschwenkt, weil er ansonsten die Entleerung behindern würde.When emptying large containers of approx. 2.5 m 3 and larger, the pouring opening is considerably wider, so that when this vehicle is also to be used to empty smaller containers, special measures must be taken to attach a lid opener. In this case, the lid opener is fitted in the pouring opening in such a way that it can be folded out or swiveled into the pouring opening when emptying smaller containers with a sliding lid. When emptying large containers, the lid opener is swung in because it would otherwise hinder the emptying.

Aus der DE-4041 483 ist ein Deckelöffner gemäß dem Oberbegriff des Anspruchs 1 mit einer pendelnd aufgehängten Schwinge bekannt, die an einem Bügel am Rande der Einschüttöffnung des Sammelbehälters gelagert ist. Der Bügel ist an seinen Enden schwenkbar gelagert und kann mit einer Antriebseinrichtung aus einer Ruheposition in eine Arbeitsposition und umgekehrt geschwenkt werden. Die pendelnd aufgehängte Schwinge kann dadurch in ihrer Arbeitsstellung unbelastet von der Antriebsrichtung des Bügels frei schwingen. Der Bügel ist ein zusätzliches Bauteil mit der Aufgabe, den eigentlichen Deckelöffner als Träger aufzunehmen und die Schwenkbarkeit des Deckelöffners zu ermöglichen. Der Bügel erfüllt weiterhin die Aufgabe, die weitaus größere Einschüttöffnung so zu überbrücken, daß der Deckelöffner in der Einschüttöffnung zum Eingriff kleinerer Behälter plaziert werden kann.From DE-4041 483 a lid opener according to the preamble of claim 1 with a pendulum-mounted rocker is known, which is mounted on a bracket on the edge of the pouring opening of the collecting container. The bracket is pivoted at its ends and can be pivoted from a rest position into a working position and vice versa with a drive device. The swinging swing arm can thus swing freely in its working position from the drive direction of the bracket. The bracket is an additional component with the task of accommodating the actual lid opener as a carrier and to enable the lid opener to be pivoted. The bracket also fulfills the task of bridging the much larger pouring opening in such a way that the lid opener can be placed in the pouring opening for the engagement of smaller containers.

Diese Ausführung hat sich zwar in der praktischen Anwendung bewährt, sie ist jedoch in einigen Fällen je nach Gestaltung der Einschüttöffnung des Sammelbehälters nicht anwendbar, wenn z.B. Großbehälter entleert werden, die vor dem Entleeren geöffnet werden müssen. Der Bügel kann in diesem Fall den geöffneten Behälterdeckel beschädigen.This version has proven itself in practical use, but in some cases it is not applicable depending on the design of the pouring opening of the collecting container, e.g. if Large containers are emptied, which must be opened before emptying. In this case, the bracket can damage the opened container lid.

Aufgabe der Erfindung ist es, einen Deckelöffner für Großraumschüttungen ohne einen zusätzlichen Träger bzw. Bügel zu schaffen, der einerseits über eine Antriebseinheit aus einer Ruhestellung in die Arbeitsstellung und umgekehrt zu verfahren ist und dennoch in seiner Arbeitsstellung frei beweglich ist, um die Zapfen des Behälterdeckels bei der Entleerung entsprechend der zwangsläufig eintretenden Bewegungsabläufe sicher zu führen und dabei keine Kraft auf die Antriebseinheiten auszuüben, die den Deckelöffner in die Arbeitsposition verschwenkt haben.The object of the invention is to provide a lid opener for large-capacity fillings without an additional carrier or bracket, which on the one hand can be moved from a rest position into the working position and vice versa via a drive unit and yet is freely movable in its working position around the pins of the container lid to guide safely during emptying in accordance with the inevitable movement sequences and not exert any force on the drive units which have pivoted the lid opener into the working position.

Diese Aufgabe wird mit einem Deckelöffner gemäß dem Anspruch 1 gelöst, bei dem die Antriebseinrichtung über einen Steuerhebel an einer horizontal angeordneten Schwenkwelle angreift, an der frei drehbar die Einrichtung zum Erfassen der Deckelzapfen befestigt ist, die mindestens ein Anschlagteil und eine Verriegelungseinrichtung aufweist, die mit dem Steuerhebel in Abhängigkeit von der Stellung der Schwenkwelle zur Festlegung des Schwenkbereichs der Einrichtung zum Erfassen der Deckelzapfen zusammenwirken.This object is achieved with a lid opener according to claim 1, in which the drive device engages via a control lever on a horizontally arranged pivot shaft, on which the device for grasping the cover pin is rotatably mounted, which device has at least one stop part and a locking device that with the control lever cooperate depending on the position of the pivot shaft to determine the pivoting range of the device for detecting the cover pin.

Für die Erfindung ist es wesentlich, daß die schwenkbare Einrichtung zum Erfassen der Deckelzapfen, die gemäß einer bevorzugten Ausführungsform zwei beabstandet angeordnete Schwenkarme mit je einem Leitblech und einem Anschlag für die Deckelzapfen umfaßt, durch die Antriebseinrichtung zwar aus der Ruhestellung in die Arbeitsstellung gefahren werden kann, jedoch in der Arbeitsstellung völlig frei beweglich ist, ohne daß irgendwelche Kräfte auf die Antriebseinrichtung ausgeübt werden.It is essential for the invention that the pivotable device for grasping the cover pin, which according to a preferred embodiment comprises two pivot arms arranged at a distance, each with a guide plate and a stop for the cover pin, can be moved from the rest position into the working position by the drive device , but is completely free to move in the working position without any forces being exerted on the drive device.

Dies wird zum einen vorzugsweise dadurch realisiert, daß der Steuerhebel beabstandet zur Schwenkwelle einen Bolzen aufweist, an dem der Schwenkarm mit seinem Anschlagteil als untere Schwenkbegrenzung anliegt. Der Steuerhebel ist vorzugsweise so ausgebildet, daß die Anlenkpunkte der Schwenkwelle und der Antriebseinrichtung oder der Steuerstange und des Bolzens ein rechtwinkliges Dreieck bilden.On the one hand, this is preferably achieved in that the control lever has a bolt spaced from the pivot shaft, on which the pivot arm rests with its stop part as the lower pivot limit. The control lever is preferably designed so that the pivot points of the pivot shaft and the drive device or the control rod and the bolt form a right-angled triangle.

Zum anderen ist die Verriegelungseinrichtung vorzugsweise als Fallklinke ausgebildet, die in Ruheposition am Bolzen angreift und die Schwenkarme verriegelt, und die beim Absenken der Schwenkarme in Arbeitsposition den Bolzen freigibt. In Ruheposition der schwenkbaren Einrichtung zum Erfassen der Deckelzapfen legt sich die Verriegelungseinrichtung über den Bolzen und verbindet dadurch den Schwenkarm mit dem Steuerhebel.On the other hand, the locking device is preferably designed as a drop latch, which engages the bolt in the rest position and locks the swivel arms, and which releases the bolt when the swivel arms are lowered into the working position. In the rest position of the swiveling device for gripping the cover pins, the locking device lies over the bolt and thereby connects the swivel arm to the control lever.

Die Fallklinke ist vorzugsweise im Bereich des Anschlagteiles der Schwenkarme frei beweglich angeordnet. Aufgrund einer entsprechenden Gewichtsverteilung befindet sich die Fallklinke auch beim Schwenken der Schwenkarmen immer in derselben Position. Dadurch ergibt sich eine Schleppvorriegelung zwischen Schwenkarmen und Steuerhebel, die so lange im Eingriff bleibt, bis die Fallklinke durch Schwerkraft vom Bolzen des Steuerhebels gelöst wird. Während der gesamten Absenkbewegung der Schwenkarme in die Arbeitsposition ruhen die Schwenkarme mit ihrem Anschlagteil auf dem Bolzen des Steuerhebels, so daß es in keinem Fall zu unkontrollierten Bewegungen der Schwenkarme kommen kann, wenn die Schleppverriegelung aufgelöst wird. Nach dem Lösen der Schleppverriegelung ist der jeweilige Schwenkarm frei um die Schwenkwelle beweglich und kann dadurch den Bewegungsabläufen der Deckelzapfen des Behälterdeckels in der erforderlichen Weise entgegenwirken und dadurch die Öffnung des Deckels erzwingen. Zum Erfassen der Deckelzapfen ist vorzugweise an jedem Schwenkarm der Anschlag für die Deckelzapfen als Fangmaul ausgebildet.The latch is preferably freely movable in the area of the stop part of the swivel arms. Due to an appropriate weight distribution, the drop latch is always in the same position even when swiveling the swivel arms. This results in a drag lock between the swivel arms and the control lever, which remains in engagement until the drop pawl is released from the bolt of the control lever by gravity. During the entire lowering movement of the swivel arms into the working position, the swivel arms rest with their stop part on the bolt of the control lever, so that there can be no uncontrolled movements of the swivel arms when the drag lock is released. After releasing the drag lock, the respective swivel arm can move freely about the swivel shaft and can thus counteract the movements of the cover pins of the container cover in the required manner and thereby force the cover to open. To grip the cover pin, the stop for the cover pin is preferably designed as a catch mouth on each swivel arm.

Gemäß einer besonderen Ausführungsform weist die Fallklinke einen Anschlagansatz auf, mit dem die Fallklinke an einem Widerlager des Steuerhebels in Arbeitsposition angreift. Dieser Anschlagansatz ist vorzugsweise derart an der Fallklinke angeordnet, daß die Öffnung der Fallklinke in der entriegelten Stellung mit dem Bolzen des Steuerhebels in etwa eine vertikale Linie bildet. Dies ist insofern vorteilhaft, als die Fallklinke bei der Aufwärtsbewegung des Steuerhebels wieder mit dem Bolzen in Eingriff gelangt und der Schwenkarm mit der dadurch hergestellten Schleppverbindung wieder in die Ruheposition gefahren werden kann.According to a special embodiment, the drop pawl has a stop with which the drop pawl engages on an abutment of the control lever in the working position. This stop approach is preferably arranged on the drop pawl in such a way that the opening of the drop pawl in the unlocked position forms approximately a vertical line with the bolt of the control lever. This is advantageous insofar as the drop pawl comes into engagement with the bolt again when the control lever moves upward and the swivel arm can be moved back into the rest position with the resulting drag connection.

Die Antriebseinrichtung kann eine druckmittelbetriebene Kolben-Zylinder-Einheit sein. Je nach Gestaltung der Einfüllöffnung des Sammelbehälters kann die Antriebseinrichtung unmittelbar am Steuerhebel angelenkt sein. Wenn es die Platzverhältnisse an der Einfüllöffnung nicht zulassen, ist zusätzlich ein Umlenkhebel und eine Steuerstange erforderlich, wobei die Steuerstange am Steuerhebel angelenkt ist und die Antriebseinrichtung am Umlenkhebel angreift.The drive device can be a pressure-medium-operated piston-cylinder unit. Depending on the design of the filling opening of the collecting container, the drive device can be articulated directly on the control lever. If the space available at the filling opening does not allow, a deflection lever and a control rod are additionally required, the control rod being articulated on the control lever and the drive device acting on the deflection lever.

In der hier gezeigten Darstellung befindet sich der Müllbehälter 5 in Einkippstellung, wobei die Schwenkarme 20 a, b die beiden Deckelzapfen 7, des Schiebedeckels 6 erfaßen. Die Einzelheiten des Deckelöffners 10, der im Bereich der Einfüllöffnung 2 angeordnet ist, wird nachfolgend im Zusammenhang mit der Figur 3 erläutert.The rear of the vehicle is shown in a side view in FIG. Below the filling opening 2, a lifting and swiveling device 4 is shown, on which the waste container 5 to be emptied is suspended. In the illustration shown here, the waste container 5 is in the tilted position, the swivel arms 20 a, b gripping the two cover pins 7, of the sliding cover 6. The details of the lid opener 10, which is arranged in the region of the filling opening 2, are explained below in connection with FIG. 3.

Der Deckelöffner 10 weist zwei parallel zueinander angeordnete Schwenkarme 20a,b auf, die an einer gemeinsamen Schwenkwelle 11 befestigt sind, die oberhalb der Einschüttöffnung 2 des Sammelbehälters angeordnet ist. Die Schwenkarme 20 a,b haben einen Abstand voneinander, der in etwa der Breite eines zur Entleerung kommenden Müllbehälters 5 in der Größe von 0,6 bis ca. 1,1 m3 entspricht, so daß deren Deckelzapfen 7 sicher von den Schwenkarmen 20 a,b erfaßt werden können. Die Schwenkarme 20 a,b bestehen normalerweise aus Rechteckrohr, an dessen freiem Ende 24 jeweils ein Leitblech 21 befestigt ist, das an seinem rückwärtigen Ende in einen Anschlag 22 übergeht, der vorzugweise als Fangmaul 23 ausgebildet ist. Das Leitblech 21 befindet sich am Schienenabschnitt 29, der über einen ersten und zweiten Verbindungsabschnitt 27, 28 in einen rechtwinklig angeordneten Endabschnitt 26 übergeht, der mit der Schwenkwelle 11 frei drehbar verbunden ist.The lid opener 10 has two pivot arms 20a, b arranged parallel to one another, which are fastened to a common pivot shaft 11, which is arranged above the pouring opening 2 of the collecting container. The swivel arms 20 a, b are at a distance from one another which corresponds approximately to the width of a waste container 5 to be emptied in the size of 0.6 to approximately 1.1 m 3 , so that the cover pin 7 thereof is securely removed from the swivel arms 20 a, b can be detected. The swivel arms 20 a, b normally consist of rectangular tube, to the free end 24 of which a guide plate 21 is fastened, which merges at its rear end into a stop 22, which is preferably designed as a catch mouth 23. The guide plate 21 is located on the rail section 29, which merges via a first and second connecting section 27, 28 into a right-angled end section 26 which is freely rotatably connected to the pivot shaft 11.

An der Schwenkwelle 11 ist drehfest ein Steuerhebel 50 befestigt, der einen Gelenkpunkt 17 aufweist, an dem eine Steuerstange 16 angreift, die mit ihrem oberen Ende an einem Umlenkhebel 15 schwenkbar befestigt ist. Der Umlenkhebel 15 ist einerseits an der Konsole 3 angelenkt, die am Sammelfahrzeug befestigt ist, und andererseits an einem Kolben 14 der Antriebseinrichtung 12 angelinkt ist. Die Antriebseinrichtung ist in der hier gezeigten Ausführungsform eine Zylinder 13 - Kolben 14 - Einheit, wobei der Zylinder 13 ebenfalls an der Konsole 3 befestigt ist. Die Antriebseinrichtung 12 dient dazu, die Schwenkarme 20 a,b von der Arbeitsposition, wie sie in Figur 3 dargestellt ist, in die Ruheposition, die in den Figuren 4 und 5 dargestellt ist, zu bewegen und umgekehrt.A control lever 50 is fastened in a rotationally fixed manner to the pivot shaft 11, said control lever having an articulation point 17 on which a control rod 16 engages, which is pivotably attached with its upper end to a bell crank 15. The bell crank 15 is articulated on the one hand on the bracket 3, which is fastened to the collecting vehicle, and on the other hand is linked to a piston 14 of the drive device 12. In the embodiment shown here, the drive device is a cylinder 13-piston 14 unit, the cylinder 13 also being fastened to the bracket 3. The drive device 12 serves to move the swivel arms 20 a, b from the working position, as shown in FIG. 3, to the rest position, which is shown in FIGS. 4 and 5, and vice versa.

In der Arbeitsposition liegt der Schwenkarm 20a mit seinem Anschlagteil 30 und mit seiner als Rundung ausgeführten Anschlagfläche 31 an einem Bolzen 51 an, der an dem Steuerhebel 50 befestigt ist. Der Steuerhebel 50 ist derart ausgebildet, daß die Schwenkwelle 11, der Gelenkpunkt 17 und der Bolzen 51 ein rechtwinkliges Dreieck bilden. An dem Anschlagteil 30 ist eine Verriegelung in Form einer Fallklinke 40 am Gelenkpunkt 41 schwenkbar befestigt. Aufgrund des Eigengewichtes fällt die Fallklinke 40 immer nach unten, allerdings nur so weit, bis der Anschlagansatz 43 an dem Steuerhebel 50 anliegt. Dies ist in der Figur 3 der Fall. Der Anschlagansatz 43 ist derart an der Fallklinke 40 angeordnet, daß in der hier gezeigten Arbeitsposition die Öffnung 42 der Fallklinke 40 in etwa senkrecht unter dem Bolzen 51 liegt, so daß der Bolzen 51 und die Öffnung 42 eine vertikale Linie bilden.In the working position, the swivel arm 20a rests with its stop part 30 and with its stop surface 31 designed as a curve against a bolt 51 which is fastened to the control lever 50. The control lever 50 is designed such that the pivot shaft 11, the pivot point 17 and the bolt 51 form a right-angled triangle. A lock in the form of a drop pawl 40 is pivotally attached to the hinge point 41 on the stop part 30. Due to its own weight, the drop pawl 40 always falls down, but only so far until the stop lug 43 abuts the control lever 50. This is the case in FIG. 3. The stop lug 43 is arranged on the drop pawl 40 that in the working position shown here Opening 42 of the drop pawl 40 lies approximately perpendicularly under the bolt 51, so that the bolt 51 and the opening 42 form a vertical line.

In der Arbeitsstellung ist die Verriegelung gelöst, und der Schwenkarm 20a liegt lediglich mit ihrer Anschlagfläche 31 am Bolzen 51 an und ist somit nach oben frei schwenkbar. Die Anschlagfläche 31 und der Bolzen 51 bilden somit die untere Anschlagbegrenzung. Beim Einschwenken eines Behälters gleiten die Deckelzapfen 7 des Behälterdeckels 6 in die Leitbleche 21 und heben die Schwenkarme 20a,b durch die weitere Schwenkbewegung an, ohne daß Druck auf den Bolzen 51 und damit auf die Antriebseinrichtung 12 ausgeübt werden kann. Die Deckelzapfen 7 gleiten bei der Einkippbewegung zunächst an dem Leitblech 21 entlang bis zum Anschlag 22. Durch die weitere Einkippbewegung wird der Deckel 6 des Behälters 5 in die Offenstellung geschoben. Mit dem Rückschwenken des Behälters wird der Deckelöffner durch die Deckelzapfen 7 wieder in die untere Arbeitsstellung zurückgeschwenkt.In the working position, the lock is released and the swivel arm 20a only rests with its stop surface 31 on the bolt 51 and is thus freely pivotable upwards. The stop surface 31 and the bolt 51 thus form the lower stop limit. When a container is swung in, the cover pins 7 of the container cover 6 slide into the guide plates 21 and raise the swivel arms 20a, b by the further swiveling movement without pressure being able to be exerted on the bolt 51 and thus on the drive device 12. During the tipping-in movement, the cover pins 7 initially slide along the guide plate 21 up to the stop 22. The further tipping-in movement pushes the cover 6 of the container 5 into the open position. When the container is pivoted back, the lid opener is pivoted back into the lower working position by the lid pin 7.

Um den Deckelöffner 10 in Ruhestellung zu bewegen, wird der Kolben 14 angezogen, so daß der Steuerhebel 16 über den Umlenkhebel 15 sich nach oben bewegt und hierbei den Steuerhebel 50 mitnimmt. Dadurch, daß die Schwenkarme 20a,b mit ihrem Anschlagteil auf dem Bolzen 51 aufliegen, werden sie mit nach oben geschwenkt, und die Öffnung 42 der Fallklinke 40 bewegt sich auf den Bolzen 51 zu und verriegelt diesen.In order to move the lid opener 10 in the rest position, the piston 14 is tightened, so that the control lever 16 moves upward via the deflection lever 15 and thereby takes the control lever 50 with it. Characterized in that the pivot arms 20a, b rest with their stop part on the bolt 51, they are pivoted upward, and the opening 42 of the drop pawl 40 moves towards the bolt 51 and locks it.

In den Figuren 4 und 5 ist die Ruhestellung des Deckelöffners 10 dargestellt. In dieser Position greift die Fallklinke 40 über den Bolzen 51 und verriegelt den Schwenkarm 20a und den Steuerhebel 50 miteinander.FIGS. 4 and 5 show the rest position of the lid opener 10. In this position, the drop pawl 40 engages over the bolt 51 and locks the swivel arm 20a and the control lever 50 together.
