Description

Die Erfindung betrifft eine Wiegevorrichtung mit Lastsensoren und einem Anzeigegerät an einem Gabelhubwagen entsprechend dem Oberbegriff des Anspruchs 1.The invention relates to a weighing device with load sensors and a Display device on a pallet truck according to the preamble of Claim 1.

Eine Last kann beispielsweise mit einer ortsfesten Waage gewogen werden, zu der eine aufgenommene Last gefahren und auf der sie abgesetzt wird.For example, a load can be weighed with a fixed scale, to which a picked-up load is driven and on which it is placed.

Es gibt aber auch die Möglichkeit, das Gewicht einer aufgenommenen Last mit einer Wiegevorrichtung an einem Gabelhubwagen zu ermitteln.But there is also the possibility of weighing a load to be determined with a weighing device on a pallet truck.

Eine bekannte Wiegevorrichtung benutzt zur Lastübertragung auf die Last­ sensoren einen Wiegerahmen oder eine Wiegeplatte (vgl. DE 34 36 552 A1). Bei einer anderen Wiegevorrichtung ist eine hydraulische Wiegezelle vor­ gesehen (vgl. GB-Z: Materials Handling News 8/1973, S. 8, 9).A known weighing device is used for load transfer to the load sensors a weighing frame or a weighing plate (see. DE 34 36 552 A1). Another weighing device has a hydraulic weighing cell seen (see GB-Z: Materials Handling News 8/1973, pp. 8, 9).

Für Kraftfahrzeuge ist es bekannt, an die Fahrzeugachsen Dehnungsmeßstreifen als Lastsensoren zur Ermittlung der aufgeladenen Last vorzusehen (vgl. DE-OS 29 13 680, DE OS 2413067, FR PS 2221326, DE Z: Automobiltechnische Zeitschrift 83/1981, Heft 5, S. 243).For motor vehicles it is known to use strain gauges on the vehicle axles to be provided as load sensors for determining the charged load (cf. DE-OS 29 13 680, DE OS 2413067, FR PS 2221326, DE Z: automotive engineering Journal 83/1981, Issue 5, p. 243).

Aufgabe der Erfindung ist es, eine weitere Wiegevorrichtung an Gabelhubwagen zu offenbaren.The object of the invention is a further weighing device on pallet trucks To reveal.

Diese Aufgabe wird mit den Merkmalen des Anspruchs 1 gelöst. Der Unteranspruch beinhaltet eine vorteilhafte Ausgestaltung.This object is achieved with the features of claim 1. The subordinate claim includes an advantageous embodiment.

Die Erfindung wird anhand von Ausführungsbeispielen erläutert.The invention is explained using exemplary embodiments.

Es zeigt:It shows:

Fig. 1 einen Gabelhubwagen ohne Fahrantrieb Fig. 1 a pallet truck without travel drive

Fig. 1A einen Gabelhubwagen mit Fahrantrieb Fig. 1A a pallet truck with travel drive

Fig. 2. 3. 4 Ausführungen der Meßachsen. Fig. 2. 3. 4 versions of the measuring axes.

Der Gabelhubwagen der Fig. 1 und der Fig. 1A wird mit 3 Meßachsen 2 aus­ gerüstet, die ihrerseits eine standfeste und querkraftfreie Signalaufnahme gewährleisten. The pallet truck of Fig. 1 and Fig. 1A is equipped with 3 measuring axes 2 , which in turn ensure a stable and lateral force-free signal recording.

Das Meßsignal wird über ein Verbindungskabel 3 an das Verstärkergerät 4 übertragen und am Anzeigegerät 5 digital sichtbar gemacht.The measurement signal is transmitted to the amplifier device 4 via a connecting cable 3 and made digitally visible on the display device 5 .

Die Speisespannung erfolgt über eine Batterie.The supply voltage is from a battery.

Bei einem Gabelhubwagen ohne Fahrantrieb wird die 3. Meßachse in die Achse der vorderen Lenkräder eingebaut, während bei Gabelhubwagen mit Fahrantrieb die 3. Meßachse in die Kolbenhubstange des Zylinders integriert ist.In a pallet truck without travel drive, the 3rd measuring axis is in the axis of the front steering wheels, while for pallet trucks with travel drive the 3rd measuring axis is integrated in the piston rod of the cylinder.

Die Meßachsen können sowohl in Tandemlaufrollen als auch in Einfachlauf­ rollen eingebaut sein.The measuring axes can be used in tandem rollers as well as in single run rolls installed.

Die verschiedenen Ausführungen der Meßachsen gehen aus den Fig. 2, 3 und 4 hervor.The different versions of the measuring axes are shown in FIGS . 2, 3 and 4.

Diese Meßachsen haben an ihren Meßstellen geeignete Dehnungsmeßstreifen (DMS), mit deren Hilfe die Spannung gemessen wird.These measuring axes have suitable strain gauges at their measuring points (DMS), with the help of which the voltage is measured.

Durch entsprechende Verstärkung wird das Meßsignal mit Hilfe von Micro­ prozessoren so aufbereitet, daß eine digitale Ablesbarkeit, an der dafür vorgesehenen Anzeige, in Kilogramm möglich ist. Die nötige Speisespannung wird aus einer Batterie oder dem Bordnetz entnommen.The measurement signal is amplified with the aid of Micro processors prepared in such a way that they can be read digitally intended display, in kilograms is possible. The necessary supply voltage is taken from a battery or the vehicle electrical system.
