Abstract

Garbage-collecting truck comprising a dumping unit, including a pour-in opening and lifting and tipping mechanism for receiving a garbage can and emptying it into the pour-in opening leading into a receiving chamber. The lifting and tipping mechanism comprises a lifting arm pivoted on a transverse axis to the dumping unit or truck chassis and carries a base team at its free end parallel to the transverse axis and pivotally movable between a receiving position in front of the driver's cab and a pouring position behind it. A carrier mounted on the base beam is extensible from one end of the rail by a fluid-operable piston-cylinder unit. A swivel arm mounted on the carrier is pivotally movable through links and a fluid operable piston-cylinder unit between a position in which it extends along the carrier, and an outer position, in which it extends approximately at right angles thereto. A coupling member carried by the swivel arm at its free end is adapted to be coupled to or grip a garbage can. A link or lever pivoted to the leading portion of the carrier and provided at its free end with a slider or roller running in a cam track is fixed to the base beam. A motion-transmitting bar connected to the link or lever and directly or indirectly linked to the swivel arm imparts to the swivel arm a pivotal movement in unison with like movement of the link or lever.

Description

Die Erfindung betrifft ein Müllsammelfahrzeug mit einer Schütteinheit, bestehend aus einer im vorderen Bereich des Fahrzeugs angeordneten Einschüttöffnung und aus einer Hubkippvorrichtung zur Aufnahme und zum Entleeren von Müllbehältern in die Einschüttöffnung eines Aufnahmeraums, wobei die Hubkippvorrichtung mindestens einen um eine Querachse der Schütteinheit oder des Chassis schwenkbaren Hubarm aufweist, der an seinem freien Ende eine zu der Querachse parallele Grundschiene trägt, die zwischen ihrem Aufnahmebereich vor dem Führerhaus und ihrem Schüttbereich hinter dem Führerhaus schwenkbar und an der ein Träger über mindestens ein Ende derselben durch eine Druckmittel-Kolben-Zylindereinheit ausfahrbar verschieblich gelagert ist, und wobei auf dem Träger ein Schwenkarm gelagert ist, der über Lenker und eine Druckmittel-Kolben-Zylindereinheit zwischen seiner an den Träger angeklappten und seiner zu diesem etwa rechtwinkelig ausgeklappten Stellung verschwenkbar ist und der an seinem freien Ende ein Kupplungsstück zum Ankuppeln und/oder Ergreifen von Müllbehältern trägt.The invention relates to a refuse collection vehicle with a pouring unit, consisting of a pouring opening arranged in the front area of the vehicle and a lifting and tipping device for receiving and emptying garbage containers into the pouring opening of a receiving space, the lifting and tilting device pivoting at least one about a transverse axis of the pouring unit or the chassis Lift arm which carries at its free end a base rail parallel to the transverse axis, which can be pivoted between its receiving area in front of the driver's cab and its dumping area behind the driver's cab and on which a carrier can be displaceably supported by at least one end thereof by means of a pressure-piston-cylinder unit is and wherein a pivot arm is mounted on the carrier, which can be pivoted via a handlebar and a pressure-piston-cylinder unit between its folded position on the carrier and its position approximately at right angles to it, and a coupling piece at its free end for coupling and / or gripping Bins.

Bei einem aus der EP-OS 163 859 bekannten Müllsammelfahrzeug dieser Art bildet der Schwenkarm zusammen mit einem im Abstand von diesem auf dem Träger angelenkten Hilfslenker mit dem an deren äußeren Enden als Koppelglied angelenktem Kupplungsstück ein Viergelenksystem, das durch eine hydraulische Kolben-Zylinder-Einheit, deren eines Ende an dem Träger und deren anderes Ende an dem Schwenkarm angelenkt ist, aus- und einschwenkbar ist. Zusätzlich ist eine Druckmittel-Kolben-Zylindereinheit vorgesehen, durch die der Träger relativ zu der Grundschiene verschoben wird, auf der dieser geführt ist. Durch das das Kupplungsstück relativ zu dem Träger verschwenkende Viergelenksystem und die beiden Druckmittel-Kolben-Zylindereinheiten, von denen eine dem Verschwenken des Kupplungsstücks und die andere dem Verschieben des Trägers dient, ist die Kinematik und Konstruktion der bekannten, das Kupplungsstück verfahrenden und verschwenkenden Einrichtung relativ kompliziert und aufwendig.In a refuse collection vehicle of this type known from EP-OS 163 859, the swivel arm forms, together with an auxiliary link articulated at a distance from it on the carrier, with the coupling piece articulated at its outer ends as a coupling member, a four-bar system which is operated by a hydraulic piston-cylinder unit , one end of which is articulated on the support and the other end of which is articulated on the swivel arm, and can be swiveled out and in. In addition, a pressure medium-piston-cylinder unit is provided, by means of which the carrier is displaced relative to the base rail on which it is guided. Due to the four-joint system pivoting the coupling piece relative to the carrier and the two pressure-medium-piston-cylinder units, one of which serves to pivot the coupling piece and the other serves to move the carrier, the kinematics and construction of the known device which moves and swivels the coupling piece is relative complicated and time-consuming.

Aufgabe der Erfindung ist es daher, eine gegenüber der bekannten Vorrichtung einfachere Einrichtung zum Ausfahren und Ausschwenken des Kupplungsstücks zu schaffen.The object of the invention is therefore to provide a device which is simpler than the known device for extending and pivoting out the coupling piece.

Erfindungsgemäß wird diese Aufgabe bei einem Müllsammelfahrzeug der gattungsgemäßen Art dadurch gelöst, daß an dem Träger in dessen in Ausschubrichtung vorderem Bereich ein Lenker oder Hebel angelenkt ist, die an ihren freien Enden einen Gleitstein oder eine Rolle tragen, die in einer mit der Grundschiene festverbundenen Kurvenführung laufen und daß mit dem Lenker oder Hebel eine Ubertragungsstange als Getriebeglied verbunden ist, die unmittelbar oder mittelbar mit dem Schwenkarm gelenkig verbunden ist und diesem entsprechend der Drehung des Lenkers oder Hebels eine Schwenkbewegung erteilt.According to the invention, this object is achieved in a refuse collection vehicle of the generic type in that a link or lever is articulated on the carrier in its front region in the direction of extension, which carries a sliding block or a roller at its free ends, which is connected in a curve guide firmly connected to the base rail run and that with the handlebars or Lever a transmission rod is connected as a gear member, which is directly or indirectly articulated to the swivel arm and this pivots according to the rotation of the handlebar or lever.

Nach einer vorteilhaften Ausgestaltung ist vorgesehen, daß mit dem Lenker im Abstand von dessen Schwenkachse kniehebelartig eine Koppelstange verbunden ist, deren anderes Ende an dem Schwenkarm im Abstand von dessen Anlenkpunkt auf dem Träger angelenkt ist. Bei der bekannten Vorrichtung erfolgt das Ausschwenken des das Kupplungsstück tragenden Schwenkarms in Abhängigkeit von der Verschiebung des Trägers auf der Grundschiene nur durch den mit der Rolle versehenen Lenker, der kniehebelartig durch eine Koppelstange mit dem Schwenkarm verbunden ist. Bei dem erfindungsgemäßen Müllsammelfahrzeug braucht daher zum Verschwenken des das Kupplungsstück tragenden Schwenkarms kein besonderer Antrieb in Form eines hydraulischen Zylinders vorgesehen zu werden. Da die Schwenkbewegung des Schwenkarms von der Ausschubbewegung des Trägers abgeleitet wird, braucht lediglich ein den Träger verschiebender Hydraulikzylinder vorgesehen zu werden.According to an advantageous embodiment, it is provided that a coupling rod is connected to the handlebar at a distance from its pivot axis, the other end of which is articulated on the pivot arm at a distance from its pivot point on the carrier. In the known device, the pivoting of the swivel arm carrying the coupling piece takes place depending on the displacement of the carrier on the base rail only by the handlebar provided with the roller, which is connected to the swivel arm like a toggle lever by a coupling rod. In the refuse collection vehicle according to the invention, no special drive in the form of a hydraulic cylinder therefore needs to be provided for pivoting the swivel arm carrying the coupling piece. Since the pivoting movement of the pivot arm is derived from the extension movement of the carrier, only a hydraulic cylinder displacing the carrier need be provided.

Das Kupplungsstück besteht zweckmäßigerweise aus einer dreieckigen Aufnahmeklaue mit keilförmig oder sphärisch gekrümmten Greifkanten, die zentrierend in eine komplementäre Aufnahmetasche der zu ergreifenden Müllbehälter einführbar sind, und ist vorzugsweise starr mit dem Greifarm verbunden. Da die Aufnahmeklaue mit einer im wesentlichen ebenen Vorderfläche versehen ist, richtet diese den zu erfassenden Müllbehälter bei einem geringfügigen Verschieben durch Ausschwenken des Greifarms relativ zu dieser aus.The coupling piece expediently consists of a triangular receiving claw with wedge-shaped or spherically curved gripping edges, which can be inserted centering into a complementary receiving pocket of the refuse containers to be gripped, and is preferably rigidly connected to the gripping arm. Since the receiving claw is provided with a substantially flat front surface, this aligns the waste container to be grasped with a slight displacement by pivoting the gripping arm relative to the latter.

Nach einer vorteilhaften Ausgestaltung ist vorgesehen, daß auf dem Träger im Abstand von der Schwenkachse des Lenkers eine Führungsstange, die eine Bohrung einer an dem Schwenkarm befestigten Gleitplatte durchsetzt und auf die eine zwischen einer in deren Schwenkbereich vorgesehenen Widerlagerplatte und der Gleitplatte eingespannte gewendelte Druckfeder aufgeschoben ist, derart gelagert ist, daß die Druckfeder am Ende der Einschwenkbewegung des Schwenkarms zunehmend gespannt wird. Die Feder wirkt als Dämpfungselement und verhindert, daß der Schwenkarm durch den den Träger verschiebenden Hydraulikzylinder mit zu großer Wucht in seine eingeschwenkte Endlage geschlagen wird.According to an advantageous embodiment it is provided that a Füh on the carrier at a distance from the pivot axis of the handlebar tion rod, which penetrates a bore of a slide plate attached to the swivel arm and onto which a helical compression spring clamped between an abutment plate provided in its swivel area and the slide plate is pushed in such a way that the compression spring is increasingly tensioned at the end of the pivoting-in movement of the swivel arm. The spring acts as a damping element and prevents the swivel arm from being struck into its swiveled-in end position by the hydraulic cylinder displacing the carrier with excessive force.

Nach einer vorteilhaften Ausgestaltung ist vorgesehen, daß der Träger aus zwei teleskopartig ineinandergeschobenen und ineinander geführten profilierten Trägerstücken besteht und daß in dem inneren Trägerstück parallel zueinander zwei hydraulische Kolben-Zylinder-Einheiten angeordnet sind, von denen beide Zylinder mit einer Bodenplatte des äußeren Trägerstücks verbunden und je eine Kolbenstange mit der Grundschiene und einer Stirnplatte des inneren Trägerstücks verbunden sind. Mit dieser Ausgestaltung läßt sich mit nur zwei kleinen hydraulischen Zylindern ein großer Ausschubweg des den Schwenkarm tragenden inneren Trägerstücks relativ zu der Grundschiene erreichen.According to an advantageous embodiment, it is provided that the carrier consists of two telescopically pushed and guided profiled carrier pieces and that two hydraulic piston-cylinder units are arranged in parallel in the inner carrier piece, both of which cylinders are connected to a base plate of the outer carrier piece and one piston rod each is connected to the base rail and an end plate of the inner support piece. With this configuration, a large extension path of the inner support piece carrying the swivel arm relative to the base rail can be achieved with only two small hydraulic cylinders.

Nach einer weiteren vorteilhaften Ausgestaltung ist vorgesehen, daß der Hebel als in dem Träger gelagerte Kurbel ausgebildet ist und daß mit der Kurbelwelle ein Hebel verbunden ist, dessen freies Ende an eine Koppelstange angelenkt ist, deren anderes Ende an dem Schwenkarm im Abstand von dessen Anlenkpunkt auf dem Träger angelenkt ist.According to a further advantageous embodiment, it is provided that the lever is designed as a crank mounted in the carrier and that a lever is connected to the crankshaft, the free end of which is articulated to a coupling rod, the other end of which is attached to the swivel arm at a distance from its articulation point is articulated to the carrier.

Die an dem freien Ende des Lenkers 21 gelagerte Rolle 22 läuft in der kanalförmigen Kurvenführung 31, die fest mit der Grundschiene 1 verbunden ist. Werden die Trägerstücke 6, 7 durch die Kolben-Zylinder-Einheiten 10, 11 nach links hin ausgefahren, wird der Schwenkarm 25 durch den Lenker 21 und die Koppelstange 27 im Uhrzeigersinn bis in seine etwa zu den Trägerstücken 8, 9 rechtwinkelige Stellung ausgeschwenkt. In den Fig. 1, 2 ist der Tragarm 25 in seiner eingeschwenkten Stellung dargestellt, in der sich die Aufnahmeklaue 30 mittig zwischen den Hubarmen 2, 3 befindet. In der nicht dargestellten ausgeschwenkten Stellung ist der die Gelenke 20, 21 tragende Bereich des inneren Trägerstücks 7 nach links bis über den Hubarm 2 hinaus ausgefahren.The roller 22 mounted on the free end of the handlebar 21 runs in the channel-shaped curve guide 31, which is fixed to the bottom rail 1 is connected. If the carrier pieces 6, 7 are extended to the left by the piston-cylinder units 10, 11, the pivot arm 25 is pivoted clockwise by the link 21 and the coupling rod 27 into its approximately rectangular position with respect to the carrier pieces 8, 9. 1, 2, the support arm 25 is shown in its pivoted-in position, in which the receiving claw 30 is located centrally between the lifting arms 2, 3. In the pivoted-out position (not shown), the area of the inner support piece 7 which carries the joints 20, 21 is extended to the left beyond the lifting arm 2.

Die Anlenkpunkte 20, 24, 26, 28 des Lenkers 21, des Hubarms 25 und der Koppelstange 27 sowie die Krümmung der Kurve 31 sind so gewählt, daß der Hubarm 25 durch Ausfahren der Trägerstücke 8, 9 in der gewünschten Weise ausgeschwenkt wird.The pivot points 20, 24, 26, 28 of the handlebar 21, the lifting arm 25 and the coupling rod 27 and the curvature of the curve 31 are selected so that the lifting arm 25 is pivoted out in the desired manner by extending the carrier pieces 8, 9.

Wie in Fig. 3 dargestellt, ist im Bereich des linken Endes des inneren Trägerstücks 7 um die Achse 40 die Stange 41 schwenkbar gelagert, die die Platte 42, die fest mit dem vorderen Bereich des Schwenkarms 25 verbunden ist, in einer Bohrung gleitend durchsetzt. Das hintere Ende der Stange 41 ist mit einer Widerlagerplatte 43 verbunden. Zwischen der Widerlagerplatte 43 und der Gleitplatte 42 ist eine gewendelte Schraubendruckfeder 44 eingespannt. Der Anlenkpunkt 40 der Stange 41 sowie die Bohrung in der Gleitplatte 42 sind so gewählt, daß die Feder 44 beim Einschwenken des Hubarms 25 in die eingeschwenkte Endstellung zunehmend gespannt wird. Damit wirkt die Feder auf die Kolben-Zylinder-Einheiten dämpfend ein, so daß ein unerwünschtes Schlagen des Schwenkarms mit hoher kinetischer Energie in die eingeschwenkte Endstellung vermieden wird.As shown in FIG. 3, in the region of the left end of the inner support piece 7, the rod 41 is pivotally mounted about the axis 40, which slides through the plate 42, which is fixedly connected to the front region of the pivot arm 25, in a bore. The rear end of the rod 41 is connected to an abutment plate 43. A helical compression spring 44 is clamped between the abutment plate 43 and the slide plate 42. The pivot point 40 of the rod 41 and the bore in the slide plate 42 are selected so that the spring 44 is increasingly tensioned when the lifting arm 25 is pivoted into the pivoted-in end position. The spring thus has a damping effect on the piston-cylinder units, so that undesired beating of the swivel arm with high kinetic energy into the swiveled-in end position is avoided.

Zur Verriegelung der an die Aufnahmeklaue 30 angekuppelten Behälter während des Hebens und Kippens ist oberhalb der Aufnahmeklaue 30 in deren eingeschwenkter Endstellung ein Widerlagerblech 48 vorgesehen, das sich stützend auf die Oberseite des oberen Randes des zu entleerenden Müllbehälters legt. Dieses Halteblech ist gegen Federkraft um einen kleinen Winkel schwenkbar gelagert und die Endlagen des Halteblechs sind durch Anschläge bildende Widerlager gesichert.In order to lock the containers coupled to the receiving claw 30 during lifting and tipping, there is a counter above the receiving claw 30 in its pivoted-in end position Bearing plate 48 is provided, which is supported on the top of the upper edge of the waste container to be emptied. This holding plate is pivotally mounted against spring force by a small angle and the end positions of the holding plate are secured by abutments forming stops.

Anhand der Fig. 6 bis 8 wird ein weiteres Ausführungsbeispiel der Steuerung für den Schwenkarm 1-25 beschrieben.Another embodiment of the control for the swivel arm 1-25 is described with reference to FIGS. 6 to 8.

Die Kurvenführung 131 ist in der vorderen Stirnseite der Grundschiene 1 vorgesehen. In dieser aus einer Führungsnut bestehenden Kurvenführung 131 läuft eine Rolle 122, die an dem freien Ende des Hebels 121 gelagert ist, der an dem inneren Ende der an dem austeleskopierbaren Trägerstück 107 gelagerten Welle 120 befestigt ist und somit eine Kurbel bildet. An dem äußeren den teleskopierbaren Träger 7 überragenden Ende der Welle bzw. Kurbelwelle 120 ist ein Hebel 128 befestigt, dessen freies Ende an eine Koppelstange 127 angelenkt ist, deren anderes Ende an den Schwenkarm 125 im Abstand von dessen Anlenkpunkt 124 auf dem austeleskopierbaren Träger 107 angelenkt ist. Die Kurbel überträgt somit bei dem Ausfahren der Träger 106, 107 eine pleuelstangenartige Bewegung auf die Koppelstange 127, die somit den Schwenkarm 125 zwischen den Endstellungen der Kurbelrolle 122 in der Kurvenführung 131 aus- und einschwenkt.The curve guide 131 is provided in the front end face of the base rail 1. In this curve guide 131 consisting of a guide groove, a roller 122 runs, which is mounted on the free end of the lever 121, which is fastened to the inner end of the shaft 120 mounted on the telescopic support 107 and thus forms a crank. A lever 128 is attached to the outer end of the shaft or crankshaft 120 projecting beyond the telescopic support 7, the free end of which is articulated to a coupling rod 127, the other end of which is articulated to the swivel arm 125 at a distance from its articulation point 124 on the telescopic support 107 is. When the supports 106, 107 are extended, the crank thus transmits a connecting rod-like movement to the coupling rod 127, which thus swivels the pivot arm 125 between the end positions of the crank roller 122 in the cam guide 131.
