Description

HUBWAGEN FÜR DEN PALETTENTRANSPORT Die Erfindung betrifft einen Hubwagen, bestehend aus zwei gabelförmig angeordneten, durch eine Traverse starr miteinander verbundenen, parallelen Tragholmen mit an ihren Enden an Hebeln gelagerten Rollen, einem am vorderen Ende angeordneten, deichselgeführten Lenkkopf sowie mit diesem und den Hebeln der Rollen gelenkig verbundenen, in den Tragholmen angeordneten Koppel stangen.PALLET TRUCK FOR PALLET TRANSPORT The invention relates to a pallet truck, consisting of two fork-shaped arranged, rigidly connected to each other by a traverse connected, parallel support bars with rollers mounted on levers at their ends, a tiller-guided steering head arranged at the front end and with this and the levers of the rollers articulated coupling arranged in the support bars rods.

Hubwagen der genannten Art sind bekannt, z.B. aus dem DE-GM 1 821 159 oder der FR-PS 1 474 055. In beiden Fällen besteht der Tragholm aus einem mit den Schenkeln nach unten weisenden, im Querschnitt U-förmigen Formteil, in dem die Hebel für die Rollen gelagert sind und das die mit diesen und mit einem im Lenkkopf angeordneten Kniehebel verbundenen Koppel stangen abdeckt.Lift trucks of the type mentioned are known, e.g. from DE-GM 1 821 159 or FR-PS 1 474 055. In both cases, the support bar consists of a with the legs pointing downwards, in cross-section U-shaped molded part in which the Levers for the rollers are stored and that with these and with one in the steering head arranged toggle linked coupling rods covers.

Beim Verladen und/oder Transportieren von Paletten ist es vielfach erwünscht, das Gewicht der auf der Palette befindlichen Ware zu kennen. Um dies zu erreichen, gibt es ortsfeste Waagen in der Form eines liegenden U, dergestalt daß der mit einer Palette beladene Hubwagen zwischen die Schenkel der Waage fährt und die Last auf diesen Schenkeln absetzt. Nach erfolgter Wägung wird die Last wieder vom Hubwagen aufgenommen.It is often the case when loading and / or transporting pallets desired to know the weight of the goods on the pallet. To this To achieve this, there are fixed scales in the shape of a lying U, like this that the pallet truck loaded with a pallet moves between the legs of the scale and put the load on these thighs. After weighing, the load becomes again picked up by the pallet truck.

Diese Arbeitsweise ist vielfach zu umständlich.This way of working is often too cumbersome.

Der Erfindung liegt daher die Aufgabe zugrunde, einen Hubwagen der eingangs genannten Art so auszubilden, daß er zum Wägen der aufgenommenen Palette geeignet ist. Hierbei ergab sich die Schwierigkeit, die Wägemeßeinrichtungen in geeigneter Weise mittig in jedem Tragholm unterzubringen und trotzdem ein einwandfreies Betätigen des Hubwagens in seiner eigentlichen Funktion zu ermöglichen.The invention is therefore based on the object of a lift truck to be designed at the outset so that it can be used to weigh the pallet picked up suitable is. Here the difficulty arose, the weighing measuring devices in suitably placed in the center of each support beam and still a perfect one To enable actuation of the lift truck in its actual function.

Die erfindungsgemäße Lösung der gestellten Aufgabe besteht in den kennzeichnenden Merkmalen des Anspruches 1. Um eine besonders genaue Wägung zu ermöglichen, sind die in den Unteransprüchen genannten Merkmale vorgesehen.The inventive solution to the task at hand consists in the Characteristic features of claim 1. In order to enable particularly accurate weighing, the features mentioned in the subclaims are provided.

Nachstehend ist die Erfindung anhand der Zeichnung näher erläutert. Es zeigen: Fig.l eine schematische Seitenansicht eines Hubwagens mit Wägeeinrichtung, Fig.2 eine Draufsicht, Fig.3 eine Einzelheit Fig.4 einen vergrößerten Querschnitt durch einen Tragholm und Fig.5 eine schematsiche Darstellung der Auflager der Wägeeinrichtung.The invention is explained in more detail below with reference to the drawing. They show: FIG. 1 a schematic side view of a lifting truck with weighing device, FIG. 2 is a plan view, FIG. 3 is a detail, FIG. 4 is an enlarged cross-section by a support beam and FIG. 5 a schematic representation of the support of the weighing device.

Der in der Zeichnung dargestellte Hubwagen besteht aus einem deichselgeführten Lenkkopf 1 mit einem daran heb- und senkbar befestigten Untergestell 2, das seinerseits aus zwei parallelen Tragholmen 3 und einer am Lenkkopf 1 angeordneten, die Tragholme 3 starr verbindenden Traverse 4 gebildet ist. An den freien Enden der Tragholme 3 sind an (nicht dargestellten) Hebeln Rollen 5 gelagert. An jedem Hebel greift eine Koppelstange 6 an, deren vorderes Ende an einem im Lenkkopf 1 angeordneten (nicht dargestellten) Kniehebel gelenkig angreift.The pallet truck shown in the drawing consists of a drawbar Steering head 1 with a raised and lowered base 2 attached to it, which in turn from two parallel support bars 3 and one arranged on the steering head 1, the support bars 3 rigidly connecting cross member 4 is formed. At the free ends of the support bars 3 rollers 5 are mounted on levers (not shown). Takes on every lever a coupling rod 6, the front end of which is arranged in the steering head 1 (not shown) articulated toggle lever engages.

Mittels der Koppelstange 6 wird eine Parallelbewegung der Hebel bewirkt, wobei die Rollen 5 gegenüber dem Untergestell verschwenkt und dieses entsprechend angehoben werden.A parallel movement of the levers is effected by means of the coupling rod 6, whereby the rollers 5 are pivoted relative to the underframe and this accordingly be raised.

Wie insbesondere Fig.2 zeigt, sind auf dem Hubwagen Wägemeßeinrichtungen 7,8,9 angeordnet. Diese sind zur Erzielung genauer Ergebnisse mittig auf der Traverse 4 sowie jeweils mittig auf jedem Tragholm 3 angeordnet und zwar, wie die Zeichnung zeigt, möglichst weit auseinander.As shown in particular in FIG. 2, weighing devices are on the lift truck 7,8,9 arranged. These are centered on the traverse to achieve precise results 4 and arranged in the middle of each support beam 3, as shown in the drawing shows as far apart as possible.

Die Wägemeßeinrichtungen 7,8,9 tragen jeweils auf ihrem beweglichen Stellglied eine Auflagerpfanne 10 und in dieser ein Kugelelement 11. Die Tragholme 3 und die Traverse 4 des Untergestells 2 werden durch eine entsprechend haubenförmig ausgebildete Wägeabdeckung 12 bedeckt. Diese weist an den den Wägemeßeinrichtungen 7,8,9 zugeordneten Stellen an ihrer Unterseite Auflagerflächen auf, wobei die den Wägemeßeinrichtungen der Traverse 4 und des einen Tragholmes 3 zugeordneten Auflagerflächen als Auflagerpfanne 13 und die der Wägemeßeinrichtung 9 als ebene Auflagerplatte 14 ausgebildet sind. Auf diese Weise können Auflagerungenauigkeiten, thermische Ausdehnungen usw. ausgeglichen werden.The weighing devices 7,8,9 each carry on their movable Actuator a support pan 10 and in this one Spherical element 11. The support bars 3 and the cross member 4 of the underframe 2 are correspondingly hood-shaped weighing cover 12 covered. This points to the weighing devices 7,8,9 assigned points on their underside bearing surfaces, the Weighing measuring devices of the cross member 4 and of the support surfaces assigned to a support beam 3 as a support pan 13 and that of the weighing measuring device 9 as a flat support plate 14 are formed. In this way, inaccuracies in the support, thermal Expansions, etc. are compensated.

Wie die Fig.2 und 3 zeigen, ist die Koppelstange 6 im Bereich der an den Tragholmen 3 angeordneten Wägemeßeinrichtungen 8,9 zweistrangig ausgebildet, wobei die beiden Stränge 15,16 der Koppelstange 6 die Wägemeßeinrichtungen 8,9 mit Abstand umgeben. In axialer Richtung ist dabei der Hub zur Betätigung der Hebel für die Rollen zu berücksichtigen.As shown in FIGS. 2 and 3, the coupling rod 6 is in the area of Weighing measuring devices 8, 9 arranged on the support bars 3 are constructed in two lines, the two strands 15, 16 of the coupling rod 6 with the weighing measuring devices 8, 9 Surrounding distance. The stroke for actuating the lever is in the axial direction for the roles to be considered.

Durch diese Ausbildung der Koppelstange 6 ist es gelungen, eine Möglichkeit zu schaffen, die Wägemeßeinrichtungen 8 und 9 zentrisch am Tragholm anzuordnen, ohne die Betätigung der Rollen mittels der Koppel stangen zu beeinträchtigen.With this design of the coupling rod 6, one possibility has been achieved to create to arrange the weighing measuring devices 8 and 9 centrally on the support beam, without affecting the actuation of the roles by means of the coupling rods.
