Abstract

The device (10) has a non-deformable fixed structure (1) serving a base receiving a non-deformable upper plate (4), upper and lower sections (2, 3), stress sensor (5) and measurement and transmission unit (6). The plate is integrated to the section (2) and receives an object to be weighed (7), and the section (3) has a receptacle for housing the unit. The plate transmits pressure of the object on the sensor, and the sensor electrically connected to the unit transmits a value of the weight to an external weight visualization device.

Description

1 Les dispositifs de pesée de charges lourdes sont plutôt répandus dans1 Heavy load weighing devices are rather common in

l'industrie. Cependant, il est des cas où la pesée ne se fait qu' à la louche car il est impossible d'installer un tel dispositif de pesée pour des raisons d'encombrement et/ou de 5 coût d'installation. L'avantage de notre Dispositif est d'être léger, portable, bas coût et utilisable dans pratiquement toutes les configurations de mesure en itinérant ou sur une installation de remplissage/vidange fixe déjà existante. 10 Ce type d'invention trouve particulièrement son application dans la mesure de cargaison de véhicules ou de bennes lors d'un contrôle de dépassement de poids autorisé ou lors d'un mesure de chargement ou de déchargement à facturer. En effet, notre invention propose un moyen original et 15 innovant de peser des objets lourds. Selon un mode particulier de réalisation du Dispositif selon l'invention, illustré par la figure 1, le dispositif de pesée (10) est placé devant l'objet à peser (7). L'objet à peser (7) avance alors sur ledit Dispositif de pesée (10) et se trouve en contact avec une plaque supérieure 20 indéformable (4) placée librement dans une structure fixe indéformable (1) servant de base de référence. Ladite plaque (4) retransmet uniformément la pression de l'objet à peser (7) sur les capteurs de contrainte (5) pris en sandwich entre deux tranches supérieure (2) et inférieure (3), flottantes réalisées en matériau 25 faiblement compressible, résistant et quasi-indéformable. Lesdits capteurs de contrainte (5) étant reliés à un moyen de mesure et de transmission sans fil (6), intégré audit Dispositif (10) retransmettent alors la valeur de la pesée à un autre dispositif externe (8) de visualisation de la pesée. 30 Selon un mode particulier de réalisation du Dispositif selon l'invention, la surface de mesure constituée de la somme des surfaces des capteurs de contrainte (5) est inférieure, selon un rapport prédéfini, à la surface totale prise en sandwich. Le moyen de mesure et de transmission sans fil (6), connaissant ledit 35 rapport de surface est capable de déduire de la pression appliquée sur les seuls capteurs le poids total de l'objet à peser. Cela présente le double avantage d'utiliser plusieurs capteurs de contrainte (5) moins résistants et moins chers, plutôt qu'un seul plus résistant et beaucoup plus cher.  industry. However, there are cases where the weighing is only ladle because it is impossible to install such a weighing device for reasons of space and / or cost of installation. The advantage of our Device is to be lightweight, portable, low cost and usable in virtually any measuring configuration while roaming or on an existing fixed filling / emptying system. This type of invention is particularly applicable in the measurement of cargo of vehicles or skips during an authorized weight overshoot or during a loading or unloading measurement to be invoiced. Indeed, our invention provides an original and innovative way of weighing heavy objects. According to a particular embodiment of the device according to the invention, illustrated by Figure 1, the weighing device (10) is placed in front of the object to be weighed (7). The object to be weighed (7) then advances on said weighing device (10) and is in contact with a non-deformable upper plate (4) placed freely in an indeformable fixed structure (1) serving as a reference base. Said plate (4) uniformly retransmits the pressure of the object to be weighed (7) on the stress sensors (5) sandwiched between two upper wafers (2) and lower (3), floating made of slightly compressible material, resistant and almost indeformable. Said stress sensors (5) being connected to a wireless measurement and transmission means (6) integrated in said device (10) then retransmit the weighing value to another external device (8) for displaying the weighing. According to a particular embodiment of the device according to the invention, the measuring surface consisting of the sum of the surfaces of the stress sensors (5) is smaller, in a predefined ratio, to the total surface sandwiched. The wireless measurement and transmission means (6), knowing said surface ratio, is able to deduce from the pressure applied to the sensors alone the total weight of the object to be weighed. This has the dual advantage of using several less resistant and less expensive strain sensors (5) rather than just one that is stronger and much more expensive.

Selon un mode particulier d'utilisation du Dispositif selon l'invention, plusieurs Dispositifs selon l'invention peuvent être utilisés pour peser un véhicule reposant sur 4 roues. Quatre Dispositifs sont placés devant les roues avant que le véhicule ne monte dessus, et la somme de chacun d'entre eux représente le poids total du véhicule, qui peut être affiché par ledit dispositif externe portable de visualisation de la pesée. Selon différents modes de réalisation du Dispositif de pesée selon l'invention, il peut être constitué d'une structure fixe indéformable (1), servant de base de référence, recevant une plaque supérieure indéformable (4), une tranche supérieure (2) flottante en matériau faiblement compressible, résistant et quasi-indéformable, des capteurs de contrainte (5), une tranche inférieure (3) flottante en matériau faiblement compressible, résistant et quasi-indéformable, un moyen de mesure et de transmission sans fil (6). Ladite plaque supérieure indéformable (4), solidaire de ladite tranche supérieure (2), peut recevoir l'objet à peser (7). Ladite tranche inférieure (3) peut contenir un réceptacle permettant d'abriter ledit moyen de mesure et de transmission sans fil (6). Lesdits capteurs de contrainte (5) peuvent être pris en sandwich et répartis sur la surface totale comprise entre lesdites deux tranches supérieure (2) et inférieure (3). Lesdits capteurs de contrainte (5) peuvent être reliés électriquement audit moyen de mesure et de transmission sans fil (6). Ledit Dispositif peut communiquer sans fil avec un dispositif externe de visualisation de la pesée. La somme des surfaces de chaque capteur de contrainte (5) peut être calculée pour être une fraction de la surface totale de contact entre les deux tranches supérieure (2) et inférieure (3), ladite fraction étant connue du moyen de mesure (6).  According to a particular mode of use of the device according to the invention, several devices according to the invention can be used to weigh a vehicle resting on 4 wheels. Four devices are placed in front of the wheels before the vehicle is mounted on them, and the sum of each of them represents the total weight of the vehicle, which can be displayed by said portable external weighing display device. According to various embodiments of the weighing device according to the invention, it may consist of a fixed, non-deformable structure (1), serving as a reference base, receiving a non-deformable top plate (4), a floating top edge (2). made of low compressible, resistant and quasi-non-deformable material, stress sensors (5), a floating bottom wafer (3) made of a weakly compressible, resistant and quasi-deformable material, a wireless measurement and transmission means (6). Said upper dimensionally stable plate (4), integral with said upper edge (2), can receive the object to be weighed (7). Said lower slice (3) can contain a receptacle for housing said measuring and wireless transmission means (6). Said strain sensors (5) can be sandwiched and distributed over the total area between said two upper (2) and lower (3) slices. Said stress sensors (5) can be electrically connected to said wireless measurement and transmission means (6). The device can communicate wirelessly with an external device for displaying the weighing. The sum of the surfaces of each stress sensor (5) can be calculated to be a fraction of the total contact area between the two upper (2) and lower (3) slices, said fraction being known from the measuring means (6) .
