One end of a piston-cylinder drive (32) engages on a toggle joint (31) of the lever, which is located between the pivot joints. The toggle lever is angled when the clamp jaw is in open position, and is extended, when the jaw is in closed position. The piston-cylinder drive may have a power accumulator, which acts in the direction of the extended toggle lever position. The spring can consist of a pre-tensioned helical pressure spring (43).

Description

Die Erfindung betrifft eine Hubvorrichtung nach dem Oberbegriff des Anspruches 1.The invention relates to a lifting device according to the preamble of 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.In such a lifting device known from EP 0 287 433 B1, the clamping jaw is designed as a simple double lever, at one end of which the clamping surface is formed and at the other end the piston rod of the piston-cylinder drive acts. When the piston rod is extended, the clamping surface is pressed against the upper edge of the vessel. If a pressure drop occurs in the piston-cylinder drive, then the clamping jaw can come loose from the edge of the vessel, so that the latter can fall out of the vessel when it is pivoted up or in its pivoted-up position.

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 is guaranteed in all operating positions.

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 characterizing part of claim 1. Characterized in that the piston-cylinder drive engages the knee joint of the knee lever and the knee lever is in the closed position of the jaw in a position bent over the extended position, the jaw cannot open, even if the pressure in the drive 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 object is also achieved by the features in the characterizing part of claim 2, since the clamping jaw is always pressed into its closed position by the energy store. It when the measures according to claim 1 and 2 are applied together is particularly advantageous, since in this case the toggle lever is pressed by the compression spring in the piston-cylinder-drive when the pressure drops into the position which is bent over the extended position and which corresponds to the closed position of the clamping jaw.

Weitere vorteilhafte und zum Teil erfinderische Ausgestaltungen ergeben sich aus den Unteransprüchen 3 bis 8.Further advantageous and partly inventive embodiments result 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 result from the description of an embodiment with reference to the drawing, which shows a lifting device in the lowered position with a waste and / or recycling container to be emptied into a disposal vehicle.

In der Zeichnung ist ein Teil einer Hubvorrichtung 1 für Müll- und/oder Wertstoff-Gefäße 2 dargestellt. Die Hubvorrichtung 1 weist eine Basiseinheit 3 auf, die an der Seitenwand 4 eines Aufnahme-Behälters 5 eines ansonsten nicht dargestellten Entsorgungsfahrzeuges befestigt wird. Mit dieser eine Haltekonstruktion bildenden Basiseinheit 3 ist mittels einer ebenfalls nur teilweise dargestellten Gelenkhebelanordnung 6 ein Hubgestell 7 verbunden, das in Form eines nur leicht abgewinkelten Winkelhebels ausgebildet ist. Im mittleren Knickbereich 8 ist eine weiter unten noch genauer zu beschreibende Greifeinrichtung 9 vorgesehen, mittels derer der obere umlaufende Rand 10 des Gefäßes 2 erfaßt und klemmend gehalten wird. Am - bezogen auf die in der Zeichnung dargestellte abgesenkte Stellung der Hubvorrichtung 1 - oberen Bereich 11 des Hubgestells 7 ist die Gelenkhebelanordnung 6 angelenkt; am gegenüberliegenden, unteren Bereich 12 ist eine Saug-Halteeinrichtung 13 als Anlage für das Gefäß 2 angeordnet, die einer vertikalen Vorderwand 14 des Gefäßes 2 zugewandt ist und diese saugend halten kann.In the drawing, part of a lifting device 1 for waste and / or recycling containers 2 is shown. The lifting device 1 has a base unit 3 which is attached to the side wall 4 of a receptacle 5 of a disposal vehicle which is otherwise not shown. A lifting frame 7 is connected to this base unit 3, which forms a holding structure, by means of an articulated lever arrangement 6, which is also only partially shown. A gripping device 9, which is to be described in more detail below, is provided in the middle kink region 8, by means of which the upper peripheral edge 10 of the vessel 2 is gripped and held in a clamped manner. On the - in relation to the lowered position of the lifting device 1 shown in the drawing - the upper region 11 of the lifting frame 7, the articulated lever arrangement 6 is articulated; on the opposite, lower area 12 a suction-holding device 13 is arranged as a system for the vessel 2, which faces a vertical front wall 14 of the vessel 2 and can hold it in suction.

An der Basiseinheit 3 ist ein Zylinder 15 eines als hydraulisch beaufschlagbarer Kolben-Zylinder-Antrieb ausgebildeten Hubantriebs 16 mittels eines Schwenkgelenks 17 angelenkt.A cylinder 15 of a lifting drive 16 designed as a hydraulically actuatable piston-cylinder drive is articulated on the base unit 3 by means of a swivel joint 17.

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 to pivot it and thus the lifting frame 7 with a vessel 2 held by it in such a way that during the last phase of the lifting movement the vessel by approximately 150 ° is rotated so that its upper opening, which is closed by a lid 18, reaches downwards over the receiving container 5, so that the contents of the vessel 2 are emptied into the receiving container 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 gripper-like gripper 19 which engages under the edge 10 of the vessel 2. The gripper 19 is fastened detachably and interchangeably to the lifting frame 7 by means of a screw connection 20.

Zur Greifeinrichtung 9 gehört weiterhin eine Klemmvorrichtung 21, die eine Klemmbacke 22 aufweist. 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.The gripping device 9 further includes a clamping device 21 which has a clamping jaw 22. The latter is pivoted on the lifting frame 7 by means of a swivel joint 23, specifically in the kink area 8 on the side facing the vessel 2. This clamping jaw 22 has a clamping surface 24 which is adapted to the design of the edge 10 of the vessel 2 and extends over the upper side thereof up to the vicinity of the lid 18. If the gripper 19 engages under the edge 10 of the vessel 2 and the clamping surface 21 abuts the edge 10 and partially overlaps it, as shown in the drawing, then the edge 10 and thus the vessel 2 is held firmly in the lifting frame 7; the front wall 14 of the vessel 2 bears against the suction holding device 13. The vessel 2 is slightly inclined with respect 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 clamping jaw 22 can be pivoted by means of a drive 25 into the described closed position encompassing the edge 10 of the vessel 2 and into an open position releasing the edge 10. For this purpose, a toggle lever 26 is provided, one lever 27 of which is pivotably mounted in the kink area 8 on the lifting frame 7 by means of a swivel joint 28, specifically on the side facing the base unit 3. The other lever 29 is pivotally connected to the jaw 22 by means of a swivel joint 30. The swivel joint 30 is arranged on the jaw 22 in such a way that an effective lever arm for the swivel joint 23 is still present in all swivel positions of the jaw 22. The two levers 27, 29 are connected to one another by means of a knee joint 31. A linear drive acts on this knee joint 31 and is formed by a piston-cylinder drive 32 which can be acted upon pneumatically. Whose cylinder 33 is pivotally mounted in the lower region 12 of the lifting frame 7 on the latter about a swivel joint 34. 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 fastened to the piston rod 35. 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. The housing space 37 delimited between the piston 36 and a guide bushing 39 is connected to a compressed air connection 40 which is guided over the guide bushing 39. The housing space 38 delimited between the piston 36 and the base 41 of the cylinder 33 is connected to a compressed air connection 42. In this housing space 38 a prestressed helical compression spring 43 is also accommodated, which is supported on the 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, when the piston rod 35 is retracted into the cylinder 33, the toggle lever 26 is bent downward and the clamping jaw 22 is pivoted away from the edge 10 of the vessel 2. The latter is therefore free of the clamping surface 24 of the jaw 22. In the one also shown in the drawing, extended from the cylinder 33 Position of the piston rod 35, in which the piston 36 abuts against the guide bush 39 as a stop, the toggle lever 26 is bent upwards slightly beyond its extended position. In this position, the clamping jaw 22 lies with its clamping surface 24 firmly against the edge 10 of the vessel 2 in the manner described.

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 pressurized with compressed air via the compressed air connection 40, so that the piston 36 with the piston rod 35 is moved 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 being supported by the force of the compression spring 43. The upper housing space 37 is vented through the compressed air connection 40. The piston 36 bears against the guide bush 39. The toggle lever 26 is brought into its slightly bent position beyond its extended position; the clamping jaw 22 engages over the edge 10 of the vessel 2 with its clamping surface 24 and holds it in the manner already described. Now, by actuating the lifting drive 16, the lifting frame 7 can be pivoted upwards with the vessel 2 for emptying into the receiving container 5. If the air pressure in the housing space 38 should drop in this case, the compression spring 43 holds the piston rod in its extended position, as a result of which the toggle lever 26 is in turn held in its slightly bent position. The jaw 22 cannot open, especially since an opening movement of the jaw would lead to a further buckling of the toggle lever 26, which in turn is not possible since the piston 36 rests in the cylinder 33 against the guide bush 39. In addition, in the raised position of the lifting frame 7, which is not shown, when the vessel 2 has rotated about 150 °, the force of gravity also acts on the piston rod 35 and the toggle lever 26 in the direction that the clamping jaw 22 is in its locking position is held.
