Description

Die Erfindung betrifft eine Hubvorrichtung nach dem Oberbegriff des Anspruches 1.The invention relates to a lifting device according to the preamble of the claim 1.

Bei einer derartigen aus der EP 0 287 433 B1 bekannten Hubvorrichtung ist die Klemmbacke als einfacher Doppelhebel ausgebildet, an dessen einem Ende die Klemmfläche ausgebildet ist und an dessen anderem Ende die Kolbenstange des Kolben-Zylinder-Antriebs angreift. Bei ausgefahrener Kolbenstange wird die Klemmfläche gegen den oberen Rand des Gefäßes gedrückt. Wenn ein Druckabfall im Kolben-Zylinder-Antrieb auftritt, dann kann sich die Klemmbacke vom Rand des Gefäßes lösen, so daß letzteres beim Hochschwenken des Hubgestells bzw. in dessen hochgeschwenkter Lage aus diesem herausfallen kann.With such a lifting device known from EP 0 287 433 B1 the jaw is designed as a simple double lever, on the the clamping surface is formed at one end and at the other end attacks the piston rod of the piston-cylinder drive. When extended Piston rod becomes the clamping surface against the top of the vessel pressed. If there is a pressure drop in the piston-cylinder drive, then the jaw can loosen from the edge of the vessel so that the latter when swiveling the lifting frame or in its swung-up position can fall out of this.

Der Erfindung liegt die Aufgabe zugrunde, die Klemmvorrichtung so auszugestalten, daß eine sichere Halterung des Gefäßes an dem Hubgestell in allen Betriebslagen gewährleistet ist.The invention has for its object to design the clamping device so that a secure mounting of the vessel on the lifting frame in all operating situations is guaranteed.

Diese Aufgabe wird erfindungsgemäß durch die Merkmale im Kennzeichnungsteil des Anspruches 1 gelöst. Dadurch, daß der Kolben-Zylinder-Antrieb am Knie-Gelenk des Kniehebels angreift und der Kniehebel in der geschlossenen Stellung der Klemmbacke in einer über die Strecklage ausgeknickten Stellung sich befindet, kann sich die Klemmbacke nicht öffnen, auch wenn der Druck im Antrieb abfällt. This object is achieved by the features in the labeling part of claim 1 solved. Because the piston-cylinder drive attacks the knee joint of the knee lever and the knee lever in the closed position of the jaw in a stretched position is in the bent position, the jaw cannot open even if the pressure in the actuator drops.

Die Aufgabe wird auch gelöst durch die Merkmale im Kennzeichnungsteil des Anspruches 2, da durch den Kraftspeicher die Klemmbacke immer in ihre Schließstellung gedrückt wird. Besonders vorteilhaft ist es, wenn die Maßnahmen nach Anspruch 1 und 2 gemeinsam angewendet werden, da hierbei der Kniehebel bei Druckabfall im Kolben-Zylinder-Antrieb von der Druckfeder in die über die Strecklage ausgeknickte Stellung gedrückt wird, die der Schließstellung der Klemmbacke entspricht.The task is also solved by the features in the labeling part of claim 2, since the jaw is always in by the energy store its closed position is pressed. It is particularly advantageous if the Measures according to claim 1 and 2 are applied together because here the toggle lever when the pressure in the piston-cylinder drive drops Compression spring pressed into the position that is bent over the extended position which corresponds to the closed position of the jaw.

Weitere vorteilhafte und zum Teil erfinderische Ausgestaltungen ergeben sich aus den Unteransprüchen 3 bis 8.Further advantageous and partly inventive configurations result resulting from subclaims 3 to 8.

Weitere Merkmale, Vorteile und Einzelheiten der Erfindung ergeben sich aus der Beschreibung eines Ausführungsbeispiels anhand der Zeichnung, die eine Hubvorrichtung in abgesenkter Stellung mit einem in ein Entsorgungsfahrzeug zu entleerenden Müll- und/oder Wertstoff-Gefäß in einer Teil-Darstellung zeigt.Further features, advantages and details of the invention emerge from the description of an embodiment with reference to the drawing, which a lifting device in the lowered position with in a disposal vehicle waste and / or recycling bin to be emptied in one Partial representation shows.

An der Basiseinheit 3 ist ein Zylinder 15 eines als hydraulisch beaufschlagbarer Kolben-Zylinder-Antrieb ausgebildeten Hubantriebs 16 mittels eines Schwenkgelenks 17 angelenkt.On the base unit 3 there is a cylinder 15 which can be acted upon hydraulically Piston-cylinder drive trained lifting drive 16 by means of a swivel joint 17 articulated.

Die nicht dargestellte Kolbenstange des Hubantriebs 16 greift an der Gelenkhebelanordnung 6 an und dient dazu, diese und damit das Hubgestell 7 mit einem von diesem gehaltenen Gefäß 2 in der Weise nach oben zu schwenken, daß während der letzten Phase der Hubbewegung das Gefäß um etwa 150° gedreht wird, so daß seine von einem Deckel 18 verschlossene obere Öffnung nach unten offen über den Aufnahme-Behälter 5 gelangt, so daß der Inhalt des Gefäßes 2 in den Aufnahme-Behälter 5 entleert wird. Derartige Hub- und Schwenkmechanismen sind bekannt, und zwar beispielsweise aus WO 91/05721.The piston rod, not shown, of the lifting drive 16 engages on the articulated lever arrangement 6 and serves this and thus the lifting frame 7 towards the top with a vessel 2 held by this swing that during the last phase of the lifting movement around the vessel is rotated about 150 ° so that its closed by a cover 18 the upper opening is open at the bottom via the receptacle 5, so that the content of the vessel 2 is emptied into the receptacle 5. Such lifting and swiveling mechanisms are known, for example from WO 91/05721.

Die Greifeinrichtung 9 weist einen in der Regel kammartig ausgebildeten Greifer 19 auf, der den Rand 10 des Gefäßes 2 untergreift. Der Greifer 19 ist mittels einer Schraubverbindung 20 am Hubgestell 7 lös- und austauschbar befestigt.The gripping device 9 has a generally comb-like design Gripper 19 which engages under the edge 10 of the vessel 2. The gripper 19 is detachable and replaceable by means of a screw connection 20 on the lifting frame 7 attached.

Letztere ist mittels eines Schwenkgelenks 23 schwenkbar am Hubgestell 7 angelenkt und zwar im Knickbereich 8 auf der dem Gefäß 2 zugewandten Seite. Diese Klemmbacke 22 weist eine der Ausgestaltung des Randes 10 des Gefäßes 2 angepaßte und diesen an seiner Oberseite bis in die Nähe des Deckels 18 übergreifende Klemmfläche 24 auf. Wenn der Greifer 19 den Rand 10 des Gefäßes 2 untergreift und die Klemmfläche 21 am Rand 10 anliegt und diesen teilweise übergreift, wie in der Zeichnung ausgezogen dargestellt ist, dann ist der Rand 10 und damit das Gefäß 2 fest im Hubgestell 7 gehalten; die Vorderwand 14 des Gefäßes 2 liegt hierbei gegen die Saug-Halteeinrichtung 13 an. Das Gefäß 2 ist hierbei leicht gegenüber seiner vertikalen Grundstellung geneigt. A gripping device 21 also belongs to the gripping device 9 has a jaw 22. The latter is by means of a swivel joint 23 pivotally articulated on the lifting frame 7 in the articulated area 8 the side facing the vessel 2. This jaw 22 has one of the Design of the edge 10 of the vessel 2 adapted and this its top up to the vicinity of the cover 18 overlapping clamping surface 24 on. If the gripper 19 engages under the edge 10 of the vessel 2 and the clamping surface 21 rests on the edge 10 and partially overlaps it, as shown in solid lines in the drawing, the edge is 10 and thus the vessel 2 is held firmly in the lifting frame 7; the front wall 14 of the vessel 2 lies against the suction-holding device 13. The Vessel 2 is slightly inclined relative to its vertical basic position.

Die Klemmbacke 22 ist mittels eines Antriebs 25 in die geschilderte den Rand 10 des Gefäßes 2 um- und übergreifende Schlußstellung und in eine den Rand 10 freigebende Öffnungsstellung verschwenkbar. Hierzu ist ein Kniehebel 26 vorgesehen, dessen einer Hebel 27 im Knickbereich 8 am Hubgestell 7 mittels eines Schwenkgelenks 28 schwenkbar gelagert ist, und zwar auf der der Basiseinheit 3 zugewandten Seite. Der andere Hebel 29 ist mittels eines Schwenkgelenks 30 mit der Klemmbacke 22 schwenkbar verbunden. Das Schwenkgelenk 30 ist derart an der Klemmbacke 22 angeordnet, daß in allen Schwenkstellungen der Klemmbacke 22 noch ein wirksamer Hebelarm zum Schwenkgelenk 23 gegeben ist. Die beiden Hebel 27, 29 sind mittels eines Kniegelenks 31 miteinander verbunden. An diesem Kniegelenk 31 greift ein Linear-Antrieb an, der durch einen pneumatisch beaufschlagbaren Kolben-Zylinder-Antrieb 32 gebildet ist. Dessen Zylinder 33 ist im unteren Bereich 12 des Hubgestells 7 an letzterem um ein Schwenkgelenk 34 schwenkbar gelagert. Das freie Ende der Kolbenstange 35 des Kolben-Zylinder-Antriebs 32 greift am Knie-Gelenk 31 an.The jaw 22 is by means of a drive 25 in the described Edge 10 of the vessel 2 encompassing and overlapping final position and in one the edge 10 opening position pivotable. This is a Knee lever 26 is provided, one lever 27 in the kink area 8 on Lifting frame 7 is pivotally mounted by means of a swivel joint 28, and on the side facing the base unit 3. The other lever 29 can be pivoted with the jaw 22 by means of a swivel joint 30 connected. The swivel joint 30 is arranged on the clamping jaw 22 in such a way that in all pivoting positions of the jaw 22 is still an effective one Lever arm for swivel joint 23 is given. The two levers 27, 29 are connected to each other by means of a knee joint 31. At this Knee joint 31 attacks a linear drive, which is controlled by a pneumatic acted upon piston-cylinder drive 32 is formed. Its cylinder 33 is in the lower region 12 of the lifting frame 7 on the latter Swivel joint 34 pivotally mounted. The free end of the piston rod 35 of the piston-cylinder drive 32 engages the knee joint 31.

Im Zylinder 33 ist ein Kolben 36 abgedichtet geführt, der an der Kolbenstange 35 befestigt ist. Er unterteilt den Innenraum des Zylinders 33 in zwei Gehäuseräume 37, 38, die druckdicht voneinander getrennt sind. Der zwischen dem Kolben 36 und einer Führungsbüchse 39 begrenzte Gehäuseraum 37 ist an einen Druckluftanschluß 40 angeschlossen, der über die Führungsbüchse 39 geführt ist. Der zwischen dem Kolben 36 und dem Boden 41 des Zylinders 33 begrenzte Gehäuseraum 38 ist an einen Druckluftanschluß 42 angeschlossen. In diesem Gehäuseraum 38 ist weiterhin eine vorgespannte Schrauben-Druckfeder 43 untergebracht, die sich einerseits gegen den Boden 41 und andererseits gegen den Kolben 36 abstützt.A piston 36 is guided in a sealed manner in the cylinder 33 and is connected to the piston rod 35 is attached. It divides the interior of the cylinder 33 into two housing spaces 37, 38, which are separated from one another in a pressure-tight manner. Of the between the piston 36 and a guide sleeve 39 limited housing space 37 is connected to a compressed air connection 40 via the Guide sleeve 39 is guided. The one between the piston 36 and the bottom 41 of the cylinder 33 limited housing space 38 is connected to a compressed air connection 42 connected. In this housing space 38 is still a preloaded compression coil spring 43 housed one hand against the bottom 41 and on the other hand against the piston 36.

Wie der Zeichnung entnehmbar ist, ist bei in den Zylinder 33 eingefahrener Kolbenstange 35 der Kniehebel 26 nach unten eingeknickt und die Klemmbacke 22 vom Rand 10 des Gefäßes 2 weggeschwenkt. Letzterer ist also von der Klemmfläche 24 der Klemmbacke 22 frei. In der in der Zeichnung ebenfalls dargestellten aus dem Zylinder 33 ausgefahrenen Stellung der Kolbenstange 35, in der der Kolben 36 gegen die Führungsbüchse 39 als Anschlag anliegt, ist der Kniehebel 26 leicht über seine Strecklage hinaus nach oben ausgeknickt. In dieser Stellung liegt die Klemmbacke 22 mit ihrer Klemmfläche 24 fest in der geschilderten Weise gegen den Rand 10 des Gefäßes 2 an.As can be seen from the drawing, the cylinder 33 is retracted Piston rod 35 of the toggle 26 bent down and the The jaw 22 is pivoted away from the edge 10 of the vessel 2. The latter is thus free of the clamping surface 24 of the jaw 22. In the in the Drawing also shown extended from the cylinder 33 Position of the piston rod 35, in which the piston 36 against the guide bush 39 is present as a stop, the toggle lever 26 is slightly over his Stretched position bent upwards. In this position the Clamping jaw 22 with its clamping surface 24 firmly in the manner described against the edge 10 of the vessel 2.

Die Wirkungsweise ist wie folgt: Vor dem Untergreifen des Randes 10 des Gefäßes 2 mittels des Greifers 19 ist die Klemmbacke 22 zurückgeschwenkt, d.h. der Gehäuseraum 37 des Zylinders 33 ist über den Druckluftanschluß 40 mit Druckluft beaufschlagt, so daß der Kolben 36 mit der Kolbenstange 35 gegen die Kraft der Druckfeder 43 in den Zylinder 33 eingefahren ist. Der Gehäuseraum 38 wird hierbei über den Druckluftanschluß 42 entlüftet. Nach dem Untergreifen des Randes 10 mittels des Greifers 19 wird der untere Druckluftanschluß 42 mit Druckluft beaufschlagt, so daß die Kolbenstange 36 aus dem Zylinder 33 ausgefahren wird, wobei diese Ausfahrbewegung durch die Kraft der Druckfeder 43 unterstützt wird. Der obere Gehäuseraum 37 wird hierbei über den Druckluftanschluß 40 entlüftet. Der Kolben 36 liegt gegen die Führungsbüchse 39 an. Der Kniehebel 26 wird hierbei über seine Strecklage hinaus in die leichte ausgeknickte Stellung gebracht; die Klemmbacke 22 übergreift mit ihrer Klemmfläche 24 den Rand 10 des Gefäßes 2 und hält dieses in der bereits geschilderten Weise. Nunmehr kann durch Betätigen des Hubantriebs 16 das Hubgestell 7 mit dem Gefäß 2 zur Entleerung in den Aufnahme-Behälter 5 nach oben verschwenkt werden. Wenn hierbei der Luftdruck im Gehäusraum 38 abfallen sollte, dann hält die Druckfeder 43 die Kolbenstange in ihrer ausgefahrenen Stellung, wodurch der Kniehebel 26 wiederum in seiner leicht ausgeknickten Stellung gehalten wird. Die Klemmbacke 22 kann sich also nicht öffnen, zumal eine Öffnungsbewegung der Klemmbacke zu einem weiteren Ausknicken des Kniehebels 26 führen würde, was wiederum nicht möglich ist, da der Kolben 36 im Zylinder 33 gegen die Führungsbüchse 39 anliegt. Hinzu kommt noch, daß in der nicht dargestellten hochgeschwenkten Stellung des Hubgestells 7, wenn sich das Gefäß 2 um etwa 150° gedreht hat, die Schwerkraft auch auf die Kolbenstange 35 und den Kniehebel 26 in der Richtung wirken, daß die Klemmbacke 22 in ihrer Verriegelungsstellung gehalten wird.The mode of operation is as follows: Before reaching under the edge 10 of the Vessel 2 by means of the gripper 19, the clamping jaw 22 is pivoted back, i.e. the housing space 37 of the cylinder 33 is via the compressed air connection 40 pressurized with compressed air so that the piston 36 with the piston rod 35 is retracted into the cylinder 33 against the force of the compression spring 43. The housing space 38 is vented via the compressed air connection 42. After reaching under the edge 10 by means of the gripper 19, the lower Compressed air connection 42 is pressurized with compressed air, so that the piston rod 36 is extended from the cylinder 33, this extension movement is supported by the force of the compression spring 43. The upper case room 37 is vented via the compressed air connection 40. Of the Piston 36 bears against the guide bush 39. The toggle lever 26 will hereby beyond its stretched position into the slightly bent position brought; the clamping jaw 22 overlaps the edge with its clamping surface 24 10 of the vessel 2 and holds it in the manner already described. Now can by lifting the actuator 16, the lifting frame 7 with the Vessel 2 is pivoted upwards for emptying into the receptacle 5 will. If the air pressure in the housing space 38 should drop here, then the compression spring 43 holds the piston rod in its extended Position, whereby the toggle lever 26 in turn in its slightly bent Position is held. The jaw 22 can not open, especially since one opening movement of the jaw to another Bending the knee lever 26 would lead, which in turn is not possible is because the piston 36 rests in the cylinder 33 against the guide sleeve 39.
