Abstract
Description
Wiegeeinrichtung für GabelstaplerWeighing device for forklifts
Die Erfindung betrifft eine Gewichtsmeßeinrichtung für Gabelstapler. Bei den bekannten Meßeinrichtungen dieser Art wird entweder der Druck in der hydraulischen Hebeeinrichtung oder die gesamte Last einschließlich des auf-und abgehenden Schlittens über Kraftmeßdosen gemessen. In beiden Fällen ist die auftretende Reibung zwischen Schlitten und Führung eine erhebliche Fehlerquelle.The invention relates to a weight measuring device for forklift trucks. In the known measuring devices of this type, either the pressure in the hydraulic Lifting device or the entire load including the up and down carriage measured via load cells. In both cases the friction that occurs is between Slide and guide are a significant source of errors.
@@@ Erfindung liegt die Aufgabe zugrunde, eine Wiegeeinrichtung Ilir Gabelstabler zu schaffen, die solche Reibungsfehler ver-@@idet. Die erfindungsgemäß Wiegeeinrichtung zeichnet sich dadurch aus, daß sie zur Gewichtsmessung vier sehr niedrige Biegebalken-Kraftaufnehmer, die mit Wälzlagerrollen bestückt sind, verwendet, welche direkt in die Lastarme des Staplers eingebaut sind.The object of the invention is to provide a weighing device Ilir To create a fork lift truck that avoids such friction errors. According to the invention Weighing device is characterized by the fact that it can measure four very weight low bending beam force transducers equipped with roller bearing rollers are used, which are built directly into the lift arms of the forklift.
Die Meterialausnehmungen für die Kraftaufnehmer sind so gering, daß praktisch keine Schwächung des Lastarme eintritt und Ihr Querschnitt nach dem Einbau der Meßeinrichtung in wesentlichen erhalben bleibt. Durch elektrisches Umschalten auf jeden Lastarm ist eine Einzelmessung möglich, um z.B. lange Laststücke gleichmäßig zu unterfangen, ferner ist die Summe der gesamten Last feststellbar.The material recesses for the force transducers are so small that practically no weakening of the load arm occurs and your cross-section after installation the measuring device is essentially retained. By electrical switching An individual measurement is possible on each load arm, e.g. to measure long loads evenly to undertake, furthermore the sum of the total load can be determined.
Das Spiel der die Last direkt aufnehmenden Schutzkästen ist so begrenzt, daß sie sich beim Anheben der Last von selbst zentrieren, durch Einrasten auf die Rollen so, daß ein reibungsfreies Messen gewährleistet wird. Auf die Darstellung der Kanäle für die elektrischen Meßleitungen ist verzichtet worden.The play of the protective boxes directly absorbing the load is so limited that that they center themselves when the load is lifted, by locking onto the Roll so that a smooth measurement is guaranteed. On the representation the channels for the electrical measuring lines have been omitted.
Anhand der ein vereinfachtes Ausführungsbeispiel dieser Gewichtsmeßeinrichtung für Gabelstapler darstellenden Abbildungen 1 bis 4 soll die Erfindung im folgenden näher beschrieben werden.Using a simplified embodiment of this weight measuring device for forklifts depicting Figures 1 to 4, the invention is intended in the following are described in more detail.
In den Abbildungen 3 und 4 ist die komplette Lastgabel mit den Senkrechtführungen 1 und den Lastarmen 2 dargestellt, die z.B. durch eine Platte 3 zusammengeschalten sind. 4 sind die beiden Schutzkästen, die durch die Stange 5 miteinander verbunden sind. Die Anordnung der vier Kraftaufnehmer 6 ist ersichtlich.Figures 3 and 4 show the complete load fork with the vertical guides 1 and the load arms 2, which are interconnected by a plate 3, for example are. 4 are the two protective boxes, which are connected to one another by the rod 5 are. The arrangement of the four force transducers 6 can be seen.
Abb. 1 ist eine annähernd naturgroße Darstellung des eingebauten Kraftaufnehmers 6 mit den Rollen 7 und einer Raststelle 8 in reil ,. 9 ist die Anordnung von Dehnungsmeßstreifen, kurz DES, genannt, 10 ist die Rollenhalterung und 14 ein einstellbarer Überlasanchlag.Fig. 1 is an approximately full-size representation of the built-in force transducer 6 with the rollers 7 and a latching point 8 in reil,. 9 is the arrangement of strain gauges, DES for short, 10 is the roll holder and 14 is an adjustable overload stop.
In Abb. 2 ist ein Schnitt durch A-B, und versetzt gezeichnet, ein Schnitt E-F durch die Begrenzungsanschläge 11 mit den Bohrungen 12, die ein so großes Spiel haben, daß die Rollen 7 immer in U einrasten. 13 sind federn, die die Schutzkästen seitlich auf Mitte Lastarm halten.In Fig. 2 is a section through A-B, drawn offset, a Section E-F through the limit stops 11 with the holes 12, which are so large Have play that the rollers 7 always lock into U. 13 are springs that hold the protective boxes Hold sideways on the middle of the load arm.
