Description

Die vorliegende Erfindung betrifft eine Hubschwenkvorrichtung für Müllfahrzeuge zum Anheben und Auskippen von Sammelbehältern, mit einer Behälteraufnahme zur Aufnahme der Sammelbehälter, einem Hubschwenkwerk mit einem Paar Schwenkarmen, mittels dessen die Behälteraufnahme von einer unteren Beladestellung in eine obere Auskippstellung und zurück schwenkbar ist, wobei die Behälteraufnahme auf einem zur Schwenkachse des Hubschwenkwerks parallelen Querträger sitzt, der mit den Schwenkarmen des Hubschwenkwerks verbunden ist, sowie mit einer Lastzelle, die zwischen die Behälteraufnahme und das Hubschwenkwerk geschaltet und zur Bestimmung des jeweils ausgekippten Müllgewichts vorgesehen ist.The present invention relates to a lifting swivel device for refuse collection vehicles for lifting and tipping over of collecting containers, with a container holder to hold the collection container, a lifting swivel with one pair Swivel arms, by means of which the container receptacle from a lower loading position is pivoted into an upper dump position and back, the container receptacle on a parallel to the swivel axis of the lifting swivel Cross member sits, which is connected to the swivel arms of the lifting swivel, as well as with a load cell between the container receptacle and the lifting swivel switched and to determine the dumped garbage weight is provided.

Derartige Hubschwenkvorrichtungen können am Heck eines Müllfahrzeuges vorgesehen sein, um Sammelbehälter für Müll, Kehricht, Reststoffe etc. vom Boden aufzunehmen und über Kopf in die Lademulde des Müllfahrzeugs zu kippen. Mittels einer Lastzelle kann das Nettogewicht des Mülls, der in die Lademulde des Müllfahrzeugs gekippt wird, gemessen werden, wobei regelmäßig weitere Gewichtsfaktoren, die beim Anheben der Sammelbehälter auftreten, wie z. B. das Gewicht des Sammelbehälters, das Gewicht der Behälteraufnahme etc. weggerechnet werden. Such lifting swivel devices can be provided at the rear of a garbage truck to collect waste, rubbish, waste, etc. from the ground and tip over into the dump truck’s loading trough. through A load cell can hold the net weight of the garbage that is in the loading bin of the garbage truck is tilted, measured, with other weight factors regularly, that occur when lifting the collection container, such as. B. the weight of the Container, the weight of the container receptacle, etc. become.

Bei Müllfahrzeugen mit sogenannten Balkenschüttungen wurde bereits vorgeschlagen, eine solche Lastzelle zwischen dem Tragrahmen der Behälteraufnahme und dem Querbalken der Hubschwenkvorrichtung, an dem der Tragrahmen befestigt ist, vorzusehen. Eine solche Anordnung ist jedoch weiter verbesserungsfähig. So wäre es wünschenswert, die Bautiefe der Lastzellenanordnung zu verringern. Weiterhin beeinträchtigt die genannte Lastzellenanordnung die Reproduzierbarkeit der Meßergebnisse.For garbage trucks with so-called beam fillings, it has already been proposed such a load cell between the support frame of the container receptacle and the crossbar of the lifting swivel device, to which the support frame is attached, provided. However, such an arrangement can be further improved. That would be it is desirable to reduce the depth of the load cell assembly. Farther the load cell arrangement affects the reproducibility of the Measurement results.

Aus der DE 200 21 543 U1 ist eine Hubschwenkvorrichtung für Müllfahrzeuge zum Anheben und Auskippen von Sammelbehältern der eingangs genannten Art bekannt, bei der die Schwenkarme des Hubschwenkgerüsts einen Querträger tragen, an dem wiederum die Behälteraufnahme in Form von zwei auskragenden Armen sitzt. Zur Erfassung des Gewichts des Schüttgutes sind ein Paar Lastzellen in die Hubschwenkvorrichtung eingebaut, mittels derer das Gewicht der aufgenommenen Sammelbehälter gemessen werden kann. Um auch bei exzentrischer Lasteinleitung eine verlässliche und präzise Wägung zu erreichen, ist in der genannten Schrift vorgeschlagen, spezielle Lastzellen zu verwenden, die mechanisch als Parallelogramm konstruiert sind. Diese speziellen Lastzellen sollen, insofern als sie sehr empfindlich sind, in einem speziellen Schutzgehäuse in die Schwenkarme des Hubschwenkwerks eingebaut werden. Obwohl diese Anordnung der Lastzellen bereits eine bessere Bestimmung des Gewichts auch außermittig angreifender Sammelbehälter erlaubt, ist die gesamte Anordnung der Lastzellen für den Praxisbetrieb ungünstig, wenig kleinbauend und aufgrund der speziellen Gestaltung der Lastzellen aufwendig.DE 200 21 543 U1 describes a lifting swivel device for refuse collection vehicles for Lifting and dumping of collecting containers of the type mentioned at the beginning, in which the swivel arms of the lifting swivel frame carry a cross member, on which in turn the container receptacle in the form of two projecting arms sitting. A pair of load cells are in the to record the weight of the bulk material Lift swivel device installed, by means of which the weight of the recorded Collection container can be measured. To even with eccentric load application To achieve reliable and precise weighing is in the document mentioned proposed to use special load cells that mechanically as a parallelogram are constructed. These special load cells are said to be very useful are sensitive, in a special protective housing in the swivel arms of the Lifting swivel be installed. Although this arrangement of the load cells already a better determination of the weight of off-center attacking containers the entire arrangement of the load cells is permitted for practical operation inconvenient, not very small and due to the special design of the load cells consuming.

Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, eine verbesserte Hubschwenkvorrichtung der genannten Art zu schaffen, die Nachteile des Standes der Technik vermeidet und letzteren in vorteilhafter Weise weiterbildet. Vorzugsweise soll eine günstige und kompakte Lastzellenanordnung geschaffen werden, die Fehlereinflüsse auf das Meßergebnis vermindert und somit besser reproduzierbare Meßwerte liefert. The present invention is therefore based on the object of improving Lift pivoting device of the type mentioned to create the disadvantages of the state avoids the technology and further develops the latter in an advantageous manner. Preferably an inexpensive and compact load cell arrangement is to be created, the influence of errors on the measurement result is reduced and thus provides more reproducible measured values.

Erfindungsgemäß wird diese Aufgabe durch eine Hubschwenkvorrichtung gemäß Anspruch 1 gelöst. Bevorzugte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.According to the invention, this object is achieved by a lifting swivel device Claim 1 solved. Preferred embodiments of the invention are the subject of subclaims.

Die Lastzelle ist also im wesentlichen parallel zur Schwenkachse des Hubschwenkwerks ausgerichtet, d.h. bei heckseitiger Anordnung der Hubschwenkvorrichtung ist die Lastzelle quer zur Fahrtrichtung des Müllfahrzeugs eingebaut. Hierdurch kann eine geringe Bautiefe erreicht werden. Die Lastzelle kann ein Paar parallele, einander gegenüberliegende Anschlußflächen besitzen, von denen her Kräfte in die Lastzelle eingeleitet werden. Bei der Ausrichtung der Lastzelle parallel zur Schwenkachse des Hubschwenkwerks liegen die genannten beiden Anschlußflächen im wesentlichen senkrecht zur Schwenkachse des Hubschwenkwerks. Die Lastzelle sitzt mit ihren Anschlußflächen dabei derart geneigt zwischen Schwenkarmen und Querträger, daß sie in einer Zwischenschwenkstellung der Behälteraufnahme zwischen deren abgesenkter Beladestellung und deren oberer Auskippstellung eine vertikale Ausrichtung einnimmt. Im Gegensatz zu bisherigen Lastzellenanordnungen, in denen die Lastzelle in der abgesenkten Beladestellung der Hubschwenkvorrichtung eine vertikale Ausrichtung einnahm, nimmt die Lastzelle durch ihre geneigte Anordnung die vertikale Ausrichtung erst dann ein, wenn die Hubschwenkvorrichtung ein Stück angehoben wird, d.h. die Behälteraufnahme bereits ein Stück geschwenkt ist.The load cell is therefore essentially parallel to the pivot axis of the lifting slewing gear aligned, i.e. with rear-side arrangement of the lifting swivel device the load cell is installed transversely to the direction of travel of the garbage truck. hereby a small installation depth can be achieved. The load cell can have a pair of parallel, have mutually opposite connection surfaces, from which forces be introduced into the load cell. When aligning the load cell parallel to The swiveling axis of the lifting swivel mechanism are the two connection surfaces mentioned essentially perpendicular to the pivot axis of the lifting swivel. The Load cell sits with its connecting surfaces so inclined between swivel arms and cross members that they in an intermediate pivoting position of the container receptacle between their lowered loading position and their upper dumping position has a vertical orientation. In contrast to previous load cell arrangements, in which the load cell in the lowered loading position of the lifting swivel device took a vertical orientation, takes the load cell through their inclined arrangement the vertical orientation only when the lift swivel device a piece is lifted, i.e. the container holder already is pivoted a bit.

In der abgesenkten Beladestellung hingegen ist die Lastzelle mit einer Hauptrichtung, in der sie zu belasten ist, bzw. in der sie zur Belastungsmessung vorgesehen ist, gegenüber der Vertikalen unter einem spitzen Winkel geneigt. Es versteht sich, daß die genannte Ausrichtung bei ebenem Stand des Müllfahrzeugs gilt. Bei der geneigten Anordnung der Lastzelle wird das Gewicht des Müllbehälters bzw. genauer gesagt das Nettogewicht des Mülls erst in einer ein Stück weit angehobenen Stellung bestimmt. Hierdurch ist der Schwerpunkt der Sammelbehälter über der Behälteraufnahme bzw. näher an der Wirkungslinie der Lastzellen. Durch die geneigte Anordnung können besser reproduzierbare Meßergebnisse erreicht werden.In the lowered loading position, however, the load cell is in one main direction, in which it is to be loaded or in which it is intended for load measurement is inclined at an acute angle to the vertical. It goes without saying that the mentioned orientation applies when the garbage truck is level. In the inclined arrangement of the load cell, the weight of the waste container or more precisely, the net weight of the garbage only in a slightly raised Position determined. As a result, the focus of the collection container is over the container receptacle or closer to the line of action of the load cells. Through the inclined arrangement can achieve more reproducible measurement results become.

Der Neigungswinkel der Lastzelle zur Vertikalen kann vorzugsweise im Bereich von 20° bis 40° liegen und insbesondere etwa 30° betragen. Die Lastzelle ist mit ihrer Hauptachse, in der die Belastungsmessung erfolgt, dann vertikal ausgerichtet, wenn die Behälteraufnahme bzw. der daran sitzende Sammelbehälter aus der abgesenkten Beladestellung um etwa 30° nach oben geschwenkt ist. Einerseits liegt damit der Sammelbehälter mit seinem Schwerpunkt bereits in etwa über der Lastzelle bzw. nahe an dieser. Andererseits kann die Belastungsmessung noch in einem relativ frühen Stadium des nach oben Schwenkens erfolgen, in dem die dynamischen Einflüsse infolge der Hubgeschwindigkeiten bzw. -beschleunigungen noch gering sind. Ferner ist der Sammelbehälter zum Zeitpunkt der Beladungsmessung noch nicht soweit nach oben gekippt, daß sein Inhalt bereits auszukippen droht.The angle of inclination of the load cell to the vertical can preferably be in the range of Are 20 ° to 40 ° and in particular be about 30 °. The load cell is with her Main axis in which the load measurement takes place, then aligned vertically, if the container receptacle or the collecting container attached to it comes out of the lowered loading position is pivoted upwards by approximately 30 °. On the one hand the collecting container with its center of gravity is already approximately above Load cell or close to it. On the other hand, the load measurement can still be in a relatively early stage of swinging up, in which the dynamic influences due to the lifting speeds and accelerations are still low. Furthermore, the collection container is at the time of loading measurement not yet tipped up so far that its contents are already tipping out threatening.

Vorzugsweise sind ein Paar Lastzellen vorgesehen, die symmetrisch zur Behälteraufnahme seitlich angeordnet sind. Hierdurch wird die Belastung der Lastzellen stark reduziert.A pair of load cells are preferably provided, which are symmetrical to the container receptacle are arranged laterally. This will reduce the load on the load cells greatly reduced.

Eine besonders günstige Anordnung der Lastzellen besteht darin, daß sie seitlich zwischen den Enden des Querbalkens sowie den Schwenkarmen des Hubschwenkwerks sitzen.A particularly favorable arrangement of the load cells is that they are on the side between the ends of the crossbeam and the swivel arms of the lifting swivel sit.

Wie Figur 1 zeigt, umfaßt die Hubschwenkvorrichtung einen sich quer zur Fahrzeuglängsrichtung erstreckenden Querträger 1, der mit seinen beiden Enden an Schwenkarmen 2 eines Hubschwenkwerks befestigt ist. Die Schwenkarme 2 erstrecken sich rechts und links des Fahrzeugs und sind mit ihren Enden an den Seitenwänden der Lademulde des Müllfahrzeugs schwenkbar befestigt. Sie können um eine sich quer zur Fahrtrichtung erstreckende Schwenkachse schwenken, um den Querträger 1 aus der in den Figuren 1 bis 3 gezeigten, unteren Beladestellung in an sich bekannter Weise nach oben zu schwenken.The lifting swivel device shown in the figures can be attached to the rear of a garbage truck can be attached with a rear loading trough. As Figure 1 shows, includes the lifting swivel device extends transversely to the longitudinal direction of the vehicle Cross member 1, with its two ends on swivel arms 2 of a lifting swivel is attached. The swivel arms 2 extend right and left of the vehicle and are with their ends on the side walls of the loading trough Garbage truck pivotally attached. You can order a cross to the direction of travel extending pivot axis pivot to the cross member 1 from the in Figures 1 to 3 shown, lower loading position in a conventional manner to pan up.

Der Querträger 1 trägt einen Tragrahmen 3, der parallel zu dem Querträger 3 ausgerichtet ist und eine Sammelbehälteraufnahme 4 bzw. einen Teil hiervon bildet. Wie die Figuren 1 und 3 zeigen, besteht der Tragrahmen 3 aus mehreren vertikalen Streben 5 sowie einer parallel zu dem Querträger 4 verlaufenden Querstrebe 6, die über zwei Hydraulikzylinder 7 relativ zu dem Querträger 1 höhenverstellbar ist. Die vertikalen Streben 5 erstrecken sich in der abgesenkten Beladestellung vertikal. Sie schwenken zusammen mit dem Querträger 1 in eine gekippte Stellung, wenn der Querträger nach oben geschwenkt wird. An dem Tragrahmen 3 können spezielle Befestigungsmittel zur Aufnahme der Sammelbehälter vorgesehen sein. In der gezeichneten Ausführung sind an dem Tragrahmen Hubzinkenlager 8 vorgesehen, an denen in der Zeichnung nicht dargestellte Hubzinken zum Greifen der Sammelbehälter schwenkbar angelenkt werden können.The cross member 1 carries a support frame 3 which is aligned parallel to the cross member 3 and forms a collecting container receptacle 4 or a part thereof. As shown in Figures 1 and 3, the support frame 3 consists of several vertical Struts 5 and a parallel to the cross member 4 cross strut 6, the is height adjustable relative to the cross member 1 via two hydraulic cylinders 7. The vertical struts 5 extend vertically in the lowered loading position. she pivot together with the cross member 1 in a tilted position when the Cross member is pivoted upwards. Special can on the support frame 3 Fastening means for receiving the collection container can be provided. In the Drawn version are provided on the support frame lifting tine bearing 8, on which lifting tines, not shown in the drawing, for gripping the collecting container can be pivoted.

Wie Figur 2 zeigt, erstreckt sich der Tragrahmen 3 in einer zu dem Querträger 1 parallelen Ebene und liegt unmittelbar an dem Querträger. In der abgesenkten Beladestellung erstreckt sich der Tragrahmen 3 vertikal, wobei die Hubzinken von dem Tragrahmen 3 entgegen der Fahrtrichtung nach hinten abstehen.As FIG. 2 shows, the support frame 3 extends in one to the cross member 1 parallel plane and lies directly on the cross member. In the lowered Loading position, the support frame 3 extends vertically, the lifting tines from protrude the support frame 3 against the direction of travel to the rear.

Die Hubschwenkvorrichtung weist weiterhin ein Paar Lastzellen 9 auf, die seitlich an den Enden des Querträgers 1 vorgesehen sind. Wie Figur 1 zeigt, sind die Lastzellen 9 zwischen den Enden des Querträgers 1 und den Schwenkarmen 2 des Hubschwenkwerks vorgesehen. Mittels der Lastzellen 9 kann bestimmt werden, welches Gewicht der jeweils aufgenommene Sammelbehälter besitzt. Dabei kann über eine entsprechende Auswerteeinrichtung das Nettogewicht des in dem Sammelbehälter befindlichen Mülls bestimmt werden. Hierzu werden das Gewicht des Sammelbehälters selbst, das Gewicht des Querträgers 1 sowie das Gewicht der Behälteraufnahme 4 abgerechnet. Gegebenenfalls könnte auch die Differenz der Gewichte der gesamten Anordnung bestimmt werden, und zwar nach dem Aufnehmen des Sammelbehälters sowie nach dem Entleeren des Sammelbehälters.The lifting swivel device further has a pair of load cells 9, which are on the side are provided at the ends of the cross member 1. As Figure 1 shows, the load cells 9 between the ends of the cross member 1 and the pivot arms 2 of the Lift swivel provided. The load cells 9 can be used to determine what weight each of the collected containers has. It can the net weight of the in the Garbage container located can be determined. For this, the weight the container itself, the weight of the cross member 1 and the weight the container holder 4 billed. If necessary, the difference could also the weights of the entire assembly can be determined after shooting of the collecting container and after emptying the collecting container.

An den Enden des Querträgers 1 ist jeweils ein Zellenträger 10 starr befestigt, und zwar über eine Verbindungsplatte 11 des Zellenträgers, die in den Figuren 4 und 5 näher gezeigt ist. Der Zellenträger besteht aus der genannten Verbindungsplatte 11, einem u-förmigen Profilteil 12, das an der Verbindungsplatte 11 befestigt, insbesondere angeschweißt ist und zur Verbindungsplatte 11 senkrecht ausgerichtet ist. Innerhalb des u-förmigen Profilteils 12 wird die Lastzelle 9 vorgesehen und mit der genannten Verbindungsplatte 11 verbunden. An der gegenüberliegenden Seite der Lastzelle 9 wird sodann eine weitere Verbindungsplatte 13 befestigt, über die die Lastzelle 9 mit dem jeweiligen Schwenkarm 2 verbunden wird. Die Lastzelle 9 sitzt also mit zwei parallelen Anschlußflächen 14 zwischen den beiden Verbindungsplatten 11 und 13, die sich senkrecht zur Schwenkachse der Hubschwenkvorrichtung, d.h. parallel zur Fahrtrichtung des Müllfahrzeugs erstrecken. Die Lastzelle 9 ist also quer zur Fahrtrichtung eingebaut. Wie Figur 4 zeigt, sind die Verbindungsplatten 11 und 13 mittels Schraubverbindungen mit der jeweiligen Lastzelle 9 sowie mit dem Querträger 1 bzw. dem jeweiligen Schwenkarm 2 verbunden.At the ends of the cross member 1, a cell support 10 is rigidly attached, and via a connecting plate 11 of the cell carrier, which is shown in FIGS is shown in more detail. The cell support consists of the connection plate mentioned 11, a U-shaped profile part 12, which is attached to the connecting plate 11, in particular is welded and aligned perpendicular to the connecting plate 11 is. Within the U-shaped profile part 12, the load cell 9 is provided and with the said connecting plate 11 connected. On the opposite side the load cell 9 is then attached a further connecting plate 13, via the the load cell 9 is connected to the respective swivel arm 2. The load cell 9 so sits with two parallel pads 14 between the two connecting plates 11 and 13, which are perpendicular to the pivot axis of the lifting swivel device, i.e. extend parallel to the direction of travel of the garbage truck. The load cell 9 is therefore installed transversely to the direction of travel. As Figure 4 shows, the connecting plates 11 and 13 by means of screw connections with the respective load cell 9 and connected to the cross member 1 or the respective swivel arm 2.

Wie insbesondere die Figuren 3 und 5 zeigen, sind die beiden Lastzellen 9 zur vertikalen Ebene des Tragrahmens 3 geneigt angeordnet. Die Lastzellen 9 besitzen eine Hauptrichtung 15, in der die Lastzellen die auf sie einwirkende Belastung messen. Die Hauptrichtung 15 schließt mit der Vertikalen 16 einen Winkel 17 von etwa 30° ein. Die Lastzellen 9 sind dabei derart geneigt, daß sie die vertikale Ausrichtung einnehmen, wenn der Querträger mit dem Tragrahmen 3 um etwa 30° nach oben geschwenkt ist. Wie Figur 3 zeigt, geht dabei die Hauptrichtung 15 etwa auf halber Höhe durch die von dem Tragrahmen 3 definierte Ebene. Diese Anordnung ergibt sich dadurch, daß die Lastzellen 9 etwa im Bereich des Querträgers 1 angeordnet und in der beschriebenen Weise geneigt sind und andererseits der Tragrahmen 3 unmittelbar an dem Querträger 1 sitzt und in der unteren Beladestellung der Hubschwenkvorrichtung eine vertikale Ausrichtung einnimmt. Diese Anordnung führt vorteilhafterweise zu besseren, d.h. besser reproduzierbaren Meßwerten. Die seitliche Anordnung der beiden Lastzellen zwischen dem Querträger und den Schwenkarmen bewirkt darüber hinaus eine bessere Krafteinleitung, eine sehr geringe Bautiefe und zudem eine Reduzierung der Zellenbelastung.As particularly shown in FIGS. 3 and 5, the two load cells 9 are vertical Level of the support frame 3 arranged inclined. The load cells 9 have a main direction 15, in which the load cells the load acting on them measure up. The main direction 15 forms an angle 17 with the vertical 16 about 30 °. The load cells 9 are inclined such that they have the vertical orientation take when the cross member with the support frame 3 by about 30 ° is pivoted upwards. As FIG. 3 shows, the main direction 15 goes approximately halfway through the plane defined by the support frame 3. This arrangement results from the fact that the load cells 9 approximately in the region of the cross member 1 arranged and inclined in the manner described and on the other hand the Support frame 3 sits directly on the cross member 1 and in the lower Loading position of the lifting swivel device assumes a vertical orientation. This arrangement advantageously leads to better, i.e. more reproducible Readings. The lateral arrangement of the two load cells between the Cross members and the swivel arms also cause better force transmission, a very shallow depth and also a reduction in cell load.
