Accordingly, the present invention is based on the object a method and an apparatus of the aforementioned Way of creating, especially when disposing of garbage the loads occurring during the movement of the lifting device considered.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß nach Messen des Gewichts der Last die Hubgeschwindigkeit nach Lastgrenzen der Antriebsvorrichtung eingestellt wird. This object is achieved in that after Measure the weight of the load Lifting speed after Load limits of the drive device set becomes.
Hierdurch ergibt sich der Vorteil, daß entsprechend dem vorliegenden Lastbetrag eine geringere oder eine höhere Hubgeschwindigkeit zum Bewegen der Hubvorrichtung aufgebracht wird; ist eine zulässige obere Lastgrenze erreicht, so blockiert die Hubvorrichtung, so daß vorteilhafterweise Unfallgefahren einwandfrei vermieden werden. This has the advantage that according to the present Load amount a lower or a higher lifting speed is applied to move the lifting device; if a permissible upper load limit is reached, the Lifting device, so that there is a risk of accident can be avoided properly.
Bei einem Verfahren, bei welchem die Antriebsvorrichtung als hydraulische Kolbenzylindereinheit ausgebildet ist, besteht die Möglichkeit, daß über den Hydraulikdruck der Kolbenzylindereinheit das Messen des Gewichts der Last erfolgt.

- a side view of the front region of a refuse collection vehicle with lifting device and drive, partly broken;
In Fig. 1 ist eine Hubvorrichtung 1 schematisch dargestellt, welche aus einem Hebelsystem besteht, dessen Hebel 4 in einem Anlenkpunkt 21 ortsfest angelenkt ist. An diesen Hebel greift eine Antriebsvorrichtung 3, beispielsweise eine Kolbenzylindereinheit mit Kolbenstange 11 an, welche in einem Gelenkpunkt 25 mit dem Hebel 4 verbunden ist. Durch Betätigung der Kolbenzylindereinheit 10 läßt sich damit beispielsweise eine auf dem Boden stehende Last 2 von einer Aufnahmestelle A zu einer Abgabestelle B bewegen, wobei im Bereich der Abgabestelle B beispielsweise ein Sammelcontainer 7 angeordnet ist. In Fig. 1, a lifting device 1 is shown schematically, which consists of a lever system, the lever 4 in one Articulation point 21 is articulated stationary. Grabs this lever a drive device 3, for example a piston-cylinder unit with piston rod 11, which at an articulation point 25 is connected to the lever 4. By actuating the piston-cylinder unit 10 can be, for example, one on the Floor load 2 from a receiving point A to a delivery point B move, for example in the area of the delivery point B. a collecting container 7 is arranged.
Ein die Last 2 aufnehmender Behälter 6 ruht auf einer Vorrichtung 30, welche dazu dient, das Gewicht der Last 2 zu ermitteln. Diese Vorrichtung kann beispielsweise ein Biegebalken, ein piezo-elektrisches Element, eine Druckmeßdose oder eine den Hydraulikdruck der Kolbenzylindereinheit 10 beeinflussende Einrichtung sein. A container 6 receiving the load 2 rests on a device 30, which serves to determine the weight of the load 2. This device can be, for example, a bending beam, a piezo-electric one Element, a pressure cell or a hydraulic pressure of the piston-cylinder unit 10 influencing device be.
Nach Ermitteln des Gewichts der im Behälter 6 befindlichen Last 2 mit Hilfe der Vorrichtung 30 wird dieser Wert über eine Leitung 31 einer Steuereinheit 32 mitgeteilt, welche ihrerseits die Antriebsvorrichtung 3, d.h. die Kolbenzylindereinheit 10 in deren Bewegungsablauf steuert. After determining the weight of the load in the container 6 2 with the aid of the device 30, this value is via a line 31 communicated to a control unit 32, which in turn the Drive device 3, i.e. the piston cylinder unit 10 in controls their movement.
Entsprechend der ermittelten Last schwenkt nun der Hebel 4, d.h. die Hubvorrichtung 1 mit geringerer oder höherer Hubgeschwindigkeit (Kurvenverlauf K) von der Aufnahmestelle A zu der Abgabestelle B: Bei geringer Last 2 erfolgt dies mit hoher Hubgeschwindigkeit - bei hoher Last 2 ist die Hubgeschwindigkeit entsprechend geringer. The lever 4 now swivels in accordance with the determined load, i.e. the lifting device 1 with a lower or higher lifting speed (Curve course K) from the pick-up point A to the delivery point B: With a low load 2, this takes place at a high lifting speed - With high load 2, the lifting speed is corresponding less.
Liegt der Betrag der Last 2 über einem zulässigen Bereich, so wird über die Steuervorrichtung 32 der Antrieb der Kolbenzylindereinheit 10 aus Sicherheitsgründen stillgesetzt, so daß eine unerwünschte Bewegung einwandfrei vermieden wird. If the amount of load 2 is over a permissible range, then is the drive of the piston-cylinder unit via the control device 32 10 shut down for security reasons, so that a unwanted movement is avoided properly.
Die Anwendung der in Fig. 1 schematisch dargestellten Vorrichtung ist in Fig. 2 anhand eines praktischen Ausführungsbeispiels näher erläutert. Hier findet beispielsweise ein Müllsammelfahrzeug 5 Anwendung, welches im vorderen Bereich als Hubvorrichtung 1 einen Hebel 4 aufweist, dessen Schwenkarm 20 im Drehpunkt 21 gelagert ist. Dieser Schwenkarm bewegt sich mit Hilfe der Antriebsvorrichtung 3, d.h. der Kolbenzylindereinheit 10, durch die Kolbenstange 11 aus der in Fig. 2 ausgezogenen Position in die im Bereich des Fahrerhauses liegende gestrichelte Lage und umgekehrt. Hierzu ist die Kolbenstange 11 über einen Gelenkpunkt 25 mit dem Schwenkarm 20 verbunden. The application of the device shown schematically in FIG. 1 is in Fig. 2 based on a practical embodiment explained in more detail. Here, for example, is a garbage collection vehicle 5 Application, which in the front area as a lifting device 1 has a lever 4, the swivel arm 20 at the pivot point 21 is stored. This swivel arm moves with the help of the drive device 3, i.e. the piston-cylinder unit 10 the piston rod 11 from the extended position in FIG the dashed position in the area of the cab and vice versa. For this purpose, the piston rod 11 is via an articulation point 25 connected to the swivel arm 20.
Der Schwenkarm 20 weist seinerseits im vorderen Bereich eine sogenannte Kammverriegelung 23 auf, welche den Kurvenverlauf K beschreibt und bei heruntergeschwenktem Schwenkarm 20 in der Lage ist, in einen Lagerbereich 24 eines die Last 2 aufnehmenden, auf den Boden stehenden Müllbehälters 6 einzugreifen. Dieser Müllbehälter 6 befindet sich in einer in ausgezogenen Linien dargestellten Anstellposition, d.h. in der Aufnahmestellung A. The swivel arm 20 in turn has one in the front area so-called comb lock 23, which the curve K describes and with the pivoted arm 20 in the Is in a storage area 24 of a load 2, to intervene on the floor of the garbage container 6. This Garbage container 6 is in a solid line shown position, i.e. in the recording position A.
Durch Schwenken des Schwenkarms 20 um den Drehpunkt 21 im Uhrzeigersinn greift die Kammverriegelung 23 des Schwenkarms 20 in den Lagerbereich 24 des gefüllten Müllbehälters 6 und hebt diesen aus der Position A zu einem sogenannten Riegelkontrollpunkt R. In diesem Riegelkontrollpunkt R wird über den Hydraulikdruck der Kolbenzylindereinheit 10 beispielsweise mit Hilfe an sich bekannter, nicht näher dargestellter Proportionalventile das Gewicht der Last 2 ermittelt und außerdem überprüft, ob die Kammverriegelung 23 des Schwenkarms 20 funktionssicher in den Lagerbereich des gefüllten Müllbehälters 6 eingreift. By pivoting the swivel arm 20 around the pivot point 21 in a clockwise direction engages the comb lock 23 of the swivel arm 20 in the storage area 24 of the filled garbage container 6 and lifts it from position A to a so-called bolt control point R. In this bolt control point R is over the hydraulic pressure the piston-cylinder unit 10, for example, with the help of itself known, not shown proportional valves that Weight of the load 2 determined and also checked whether the Comb lock 23 of the swivel arm 20 functionally reliable in the Storage area of the filled waste container 6 engages.
Nach Ermittlung des Gewichts der Last 2 wird analog der schematischen Ausführungsform nach Fig. 1 die funktionsrichtige, auf die Last des gefüllten Müllbehälters 6 abgestellte Hubgeschwindigkeit festgelegt, wonach sich der Schwenkarm 20 mit Hilfe der Kolbenzylindereinheit 10 in die Abgabeposition B bewegt, in welcher der Behälter 6 in eine Kipposition gelangt und dort der Müll in einen schematisch dargestellten Sammelbehälter 7 bzw. in eine Schubvorrichtung abgegeben wird, von welcher der Müll z.B. über einen Preßstempel in den Müllsammelbehälter weitergeschoben wird. After determining the weight of the load 2 is analogous to the schematic Embodiment according to Fig. 1, the functional, on the load of the filled garbage container 6 lift speed determined, after which the swivel arm 20 using the Piston-cylinder unit 10 moved into the delivery position B, in which the container 6 comes into a tilt position and there the Rubbish in a schematically illustrated collection container 7 or in a pusher is delivered from which the garbage e.g. pushed into the garbage collector via a press ram becomes.
Erfindungsgemäß ergibt sich also eine spezielle Verknüpfung des Gewichts, d.h. der Last 2 in dem Behälter 6 mit der Fördergeschwindigkeit, d.h. der Hubgeschwindigkeit des Schwenkarms 20. Es können beispielsweise zwei Geschwindigkeiten vorgesehen sein, z.B. eine hohe Geschwindigkeit bis zu 240 kg und in den Bereichen zwischen 240 und 550 kg eine geringere Hubgeschwindigkeit. Oberhalb einer Last von 550 kg ist vorteilhafterweise die Hubvorrichtung 1, d.h. der Schwenkarm 20, mit dessen Antrieb über die Kolbenzylindereinheit 10 blockiert, um Überlastung und Unfallgefahr zu vermeiden. According to the invention, there is therefore a special link between the Weight, i.e. the load 2 in the container 6 at the conveying speed, i.e. the lifting speed of the swivel arm 20. For example, two speeds can be provided e.g. a high speed up to 240 kg and in the fields between 240 and 550 kg a lower lifting speed. The lifting device is advantageously above a load of 550 kg 1, i.e. the swivel arm 20, with its drive over the piston-cylinder unit 10 blocked to overload and risk of accident to avoid.
Durch die erfindungsgemäße Verknüpfung des Gewichts der Last 2 mit der Fördergeschwindigkeit des Schwenkarms 20 mit Hilfe des erfindungsgemäßen Verfahrens ergibt sich ein rationeller Arbeitsablauf, welcher insbesondere beim Entsorgen von Müll mit Hilfe eines Müllsammelfahrzeuges kosteneffektiv ist. By linking the weight of the load 2 according to the invention with the conveying speed of the swivel arm 20 using the A method according to the invention results rational workflow, which is particularly important when disposing of garbage using a garbage collection vehicle cost-effectively is.
