Description

"Dispositif d'identification d'un objet à l'aide d'un insert incorporé à cet ob et""Device for identifying an object using an insert incorporated into this ob and"
L'invention concerne un dispositif d'identification d'un objet, le cas échéant pour sélectionner cet objet parmi d'autres objets, du type comprenant un insert incorporé audit objet et présentant des paramètres de configuration constituant un code d'identification de l'objet et détectables à l'aide d'un moyen de détection tel qu'un faisceau de rayons X ou ultrasons ou un champ magnétique, et un émetteur dudit moyen de détection ainsi qu'un récepteur du moyen de détection après l'interaction avec ledit insert.The invention relates to a device for identifying an object, if necessary for selecting this object from other objects, of the type comprising an insert incorporated into said object and having configuration parameters constituting an identification code of the object and detectable using a detection means such as an X-ray or ultrasound beam or a magnetic field, and an emitter of said detection means as well as a receiver of the detection means after interaction with said insert.
On connait déjà des dispositifs de ce type. Les paramètres de configuration de l'insert sont constitués par une partie d'une configuration particulière, telle qu'une encoche, le cas échéant, d'une forme complexe, ou une surface porteuse par exemple d'un code barres.Devices of this type are already known. The configuration parameters of the insert consist of a part of a particular configuration, such as a notch, if necessary, of a complex shape, or a support surface, for example of a bar code.
Il s'est avéré que des inserts de ce type ne sont pas utilisables dans certains cas d'application. Ainsi, pour la réalisation de stractures complexes telles que des véhicules automobiles, à partir de pièces préfabriquées, à l'aide de robots et de chaînes de montage automatiques, il est nécessaire de pouvoir sélectionner chaque pièce parmi un grand nombre d'autres pièces. Pour résoudre ce problème, on a envisagé d'incorporer à ces pièces des inserts d'identification. Or on a constaté l'inconvénient des inserts jusqu'à présent utilisés, qui réside dans le fait que la sûreté de l'identification des pièces devant être sélectionnées est très faible en raison de la variation de l'orientation de l'insert dans le faisceau ou champ du moyen de détection. Dans la mesure où il est trop coûteux et pratiquement impossible d'assurer toujours la même orientation de l'insert, ce mode par ailleurs très propice d'identification n'est pas applicable dans tous les cas d'utilisation où cette orientation invariable d'une pièce à l'autre ne peut pas être strictement assurée. La présente invention a pour but de proposer un dispositif d'identification d'un objet à l'aide d'un insert, du type décrit plus haut, qui est applicable à des cas d'utilisation jusqu'à présent exclus.It has been found that inserts of this type cannot be used in certain application cases. Thus, for the production of complex structures such as motor vehicles, from prefabricated parts, using robots and automatic assembly lines, it is necessary to be able to select each part from a large number of other parts. To resolve this problem, it has been envisaged to incorporate identification inserts into these parts. However, the drawback of the inserts hitherto used has been noted, which lies in the fact that the reliability of the identification of the parts to be selected is very low due to the variation of the orientation of the insert in the beam or field of the detection means. Insofar as it is too expensive and practically impossible to always ensure the same orientation of the insert, this otherwise very suitable mode of identification is not applicable in all use cases where this invariable orientation of one room to another cannot be strictly insured. The present invention aims to provide a device for identifying an object using an insert, of the type described above, which is applicable to use cases hitherto excluded.
Pour atteindre ce but, le dispositif selon l'invention est caractérisé en ce que l'insert présente une forme sphérique comportant plusieurs éléments sphériques concentriques, qui sont réalisés en des matériaux ayant une transparence au moyen de détection, différente d'un élément à l'autre, et augmentant du centre à la périphérie de l'insert, les paramètres de configuration étant formés par les diamètres desdits éléments concentriques.To achieve this object, the device according to the invention is characterized in that the insert has a spherical shape comprising several concentric spherical elements, which are made of materials having a transparency by means of detection, different from an element with l other, and increasing from the center to the periphery of the insert, the configuration parameters being formed by the diameters of said concentric elements.
L'invention sera mieux comprise et d'autres buts, caractéristiques détails et avantages de celle-ci apparaîtront plus clairement au cours de la description explicative qui va suivre faite en référence aux dessins schématiques annexés donnés uniquement à titre d'exemple illustrant plusieurs modes de réalisation de l'invention et dans lesquels :The invention will be better understood and other objects, characteristics, details and advantages thereof will appear more clearly during the explanatory description which follows, made with reference to the appended schematic drawings given solely by way of example illustrating several modes of realization of the invention and in which:
la figure 1 est une vue en coupe d'un insert de forme sphérique, selon l'invention, qui passe à travers le centre de cet insert;Figure 1 is a sectional view of a spherical shaped insert, according to the invention, which passes through the center of this insert;
la figure 2 est une vue schématique et en perspective avec arrachement partiel d'un dispositif d'identification selon l'invention, impliquant l'emploi d'un insert selon la figure 1, dans le contexte d'un exemple d'utilisation.Figure 2 is a schematic perspective view with partial cutaway of an identification device according to the invention, involving the use of an insert according to Figure 1, in the context of an example of use.
Comme le montre la figure 1, un insert selon l'invention présente une forme sphérique et se compose d'une pluralité d'éléments sphériques concentriques. Dans l'exemple de la figure 1, l'insert 1 comporte trois éléments concentriques portant les références 2, 3 et 4, dans le sens du centre à la périphérie. Les différents éléments concentriques sont réalisés dans des matériaux différents, choisis de façon que la transparence au moyen de détection de l'élément intermédiaire 3 soit supérieure à celle de l'élément central 2 et inférieure à celle de l'élément radialement externe 4. La structure de l'insert 1 est caractérisée par les différents diamètres dl, d2 et d3 de ces éléments constitutifs 2 à 4.As shown in Figure 1, an insert according to the invention has a spherical shape and consists of a plurality of concentric spherical elements. In the example of FIG. 1, the insert 1 comprises three concentric elements bearing the references 2, 3 and 4, in the direction from the center to the periphery. The various concentric elements are made of different materials, chosen so that the transparency by means of detection of the intermediate element 3 is greater than that of the central element 2 and less than that of the radially external element 4. The structure of the insert 1 is characterized by the different diameters dl, d2 and d3 of these constituent elements 2 to 4.
Comme le montre la figure 2, pour identifier l'objet, tel qu'une pièce de construction 6 ou 7, on incorpore l'insert 1 à la pièce. Comme l'illustre la figure 2, la structure de l'insert est détectable à l'aide d'un équipement comprenant un émetteur 9 du moyen de détection 10, tel que l'émetteur d'un faisceau de rayons X, d'un faisceau de signaux ultrasons ou d'un champ magnétique; et un récepteur 11 du moyen de détection après son interaction avec l'insert. Bien entendu, il faut que la transparence au moyen de détection du matériau de la pièce de construction 6 ou 7 soit très supérieure à celle de l'élément radialement externe 4 de l'insert. Dans ces conditions, le récepteur 11 sera en mesure de restituer la structure de l'insert sous forme d'une image de projection faisant clairement apparaître les différents éléments constitutifs de l'insert et les dimensions de ceux-ci. Bien entendu, le matériau constituant les pièces 6, 7 doit être transparent au moyen de détection. A l'aide d'un d spositif d'exploitation de cette image, selon un programme de calcul approprié, un dispositif calculateur 12 peut établir le code d'identification formé par des mises en rapport des diamètres dl, d2 et d3.As shown in FIG. 2, to identify the object, such as a building part 6 or 7, the insert 1 is incorporated into the part. As illustrated in FIG. 2, the structure of the insert is detectable using equipment comprising an emitter 9 of the detection means 10, such as the emitter of an X-ray beam, of a beam of ultrasonic signals or magnetic field; and a receiver 11 of the detection means after its interaction with the insert. Of course, the transparency by means of detection of the material of the construction part 6 or 7 must be much greater than that of the radially external element 4 of the insert. Under these conditions, the receiver 11 will be able to reproduce the structure of the insert in the form of a projection image clearly showing the various constituent elements of the insert and the dimensions thereof. Of course, the material constituting the parts 6, 7 must be transparent by means of detection. With the aid of a device for exploiting this image, according to an appropriate calculation program, a calculating device 12 can establish the identification code formed by relating the diameters d1, d2 and d3.
En fonction du résultat établi par le dispositif 12, dans l'exemple représenté, la pièce 6 ou 7 sera transférée par des moyens non représentés mais connus en soi, vers la zone d'accueil 14 ou 15.Depending on the result established by the device 12, in the example shown, the part 6 or 7 will be transferred by means not shown but known per se, to the reception area 14 or 15.
A titre d'exemple, lorsque l'on utilise comme moyen détecteur des rayons X, l'élément central 2 de l'insert pourrait être réalisé en plomb, et les éléments 3 et 4 respectivement en argent et en alumine. Ces matériaux ont été nommés uniquement à titre d'exemple pour illustrer l'augmentation de la transparence aux rayons X du centre à la périphérie de l'insert. Toute autre combinaison de matériaux qui satisfait à cette exigence concernant la transparence des matériaux peut être retenue. Il est évident que les combinaisons possibles de codage peuvent être augmentées par variation des diamètres et/ou par variation du nombre des éléments concentriques. On comprend aisément qu'en raison de sa forme sphérique, la sûreté de détection de l'insert n'est pas affectée par une modification de la position des pièces 6 ou 7 dans le moyen de détection. De la même manière, le positionnement de l'insert dans son objet récepteur ne pose aucun problème, également en raison de la forme sphérique de l'insert. For example, when using as an X-ray detector means, the central element 2 of the insert could be made of lead, and the elements 3 and 4 respectively of silver and alumina. These materials have been named only by way of example to illustrate the increase in transparency to X-rays from the center to the periphery of the insert. Any other combination of materials which meets this requirement concerning the transparency of the materials may be selected. It is obvious that the possible coding combinations can be increased by varying the diameters and / or by varying the number of concentric elements. It is easily understood that due to its spherical shape, the detection reliability of the insert is not affected by a modification of the position of the parts 6 or 7 in the detection means. Similarly, the positioning of the insert in its receiving object poses no problem, also due to the spherical shape of the insert.
