Abstract
Description
L'invention est relative à un dispositif de détection d'outil ou d'accessoire pour machine, notamment pour chariot de manutention.The invention relates to a tool detection device or machine accessory, in particular for a handling trolley.
L'invention est particulièrement avantageuse dans son application à des chariots de manutention tout terrain, cette application étant soumise à des contraintes réglementaires de sécurité élevées.The invention is particularly advantageous in its application to off-road forklifts, this application being subject to high safety regulatory requirements.
Les chariots de manutention tout terrain, en particulier les chariots à bras télescopique, peuvent être utilisés comme élévateurs de charges, chargeuses, grues, nacelles élévatrices de personnes, et autres applications de manipulation de charge déportée.Off-road trucks, especially telehandlers, can be used as load lifters, loaders, cranes, boom lifts, and other remote load handling applications.
Pour effectuer ces applications, les chariots de manutention tout terrain sont conformés en porte-outils, et nécessitent par conséquent de changer d'outil ou d'accessoire selon l'application utilisée par l'opérateur.To carry out these applications, the all-terrain forklift trucks are designed as tool holders, and consequently require the tool or accessory to be changed according to the application used by the operator.
L'utilisation du chariot de manutention est différente en fonction de l'application et nécessite un réglage particulier pour assurer le bon fonctionnement de l'assemblage du chariot tout terrain et de l'outil ou accessoire correspondant.The use of the industrial truck differs according to the application and requires special adjustment to ensure the proper functioning of the assembly of the truck and the tool or accessory.
Ainsi, l'utilisation d'un chariot de manutention pour une application de chargeuse nécessite force et rapidité, tandis qu'une application d'un chariot de manutention pour le placement de charge nécessite une finesse de positionnement et une précision du mouvement.Thus, the use of a truck for a loader application requires strength and speed, while an application of a truck for load placement requires a fineness of positioning and precision of movement.
Un premier but de l'invention est de permettre la détection d'un outil ou d'un accessoire pour adapter et optimiser le comportement de la machine ou du chariot tout terrain à l'outil ou à l'accessoire utilisé, en vue d'assurer le bon fonctionnement de leur assemblage.A first object of the invention is to enable the detection of a tool or an accessory for adapting and optimizing the behavior of the machine or the off-road carriage to the tool or the accessory used, with a view to ensure the proper functioning of their assembly.
La détection de l'outil ou de l'accessoire permet ainsi de répondre aux contraintes législatives ou normatives relatives à l'utilisation correspondante, d'adapter le comportement du chariot de manutention ou de la machine en adaptant le niveau de sécurité requis à l'accessoire ou outil utilisé, de limiter ou d'interdire éventuellement l'utilisation d'un accessoire ou d'un outil pour une utilisation inappropriée à un type de machine ou de chariot de manutention, de permettre la restitution automatique des réglages personnels de l'opérateur, de régler automatiquement la cartographie des débits hydrauliques, de régler les abaques de charges en fonction de l'accessoire ou de l'outil, et/ou d'autoriser le fonctionnement de l'accessoire ou de l'outil après reconnaissance du type d'accessoire ou d'outil homologué par le constructeur de la machine ou du chariot tout terrain.The detection of the tool or accessory thus makes it possible to meet the legislative or normative constraints relating to the corresponding use, to adapt the behavior of the industrial truck or of the machine by adapting the required level of safety to the accessory or tool used, to limit or possibly prohibit the use of an accessory or tool for improper use to a type of machine or industrial truck, to allow the automatic return of personal settings of the operator, to settle automatically charting the hydraulic flows, adjusting the load charts according to the accessory or the tool, and / or authorizing the operation of the accessory or the tool after recognizing the type of accessory or approved by the manufacturer of the machine or off-road truck.
Les accessoires ou les outils utilisés peuvent être des accessoires monobloc ne nécessitant aucune puissance, par exemple un godet de chargement ou un portepique.The accessories or tools used may be one-piece accessories requiring no power, for example a loading bucket or a portico.
Les accessoires ou les outils utilisés peuvent être des accessoires ou outils demandant une alimentation en puissance hydraulique ou en puissance électrique généralement fournie par le chariot de manutention ou la machine à laquelle l'outil ou accessoire est destiné. Ces types d'outils ou d'accessoires nécessitant un apport de puissance pour leur fonctionnement sont généralement constitués en plusieurs parties articulées ou mobiles les unes par rapport aux autres : désileuses, pinces, enrouleuses ou dérouleuses, manipulateurs multiaxes, ou analogues.The accessories or tools used may be accessories or tools requiring a supply of hydraulic power or electrical power generally provided by the industrial truck or the machine to which the tool or accessory is intended. These types of tools or accessories requiring a power supply for their operation are generally made of several parts articulated or movable relative to each other: unloaders, clamps, winders or unwinders, multi-axis manipulators, or the like.

L'invention a pour objet un dispositif de détection d'outil ou d'accessoire pour machine, notamment pour chariot de manutention, dans lequel le dispositif comporte un organe d'identification passif solidaire d'un outil ou accessoire et un moyen actif de reconnaissance solidaire de la machine ou chariot de manutention, de manière à identifier l'outil ou accessoire en vue du bon fonctionnement de leur assemblage, dans lequel la reconnaissance de l'organe d'identification passif par le moyen actif de reconnaissance est une reconnaissance sans contact, dans lequel l'organe d'identification passif est un organe magnétique passif et le moyen de reconnaissance actif est un moyen actif de détection magnétique, caractérisé par le fait que l'organe magnétique passif est un organe à motif magnétique comportant plusieurs pôles magnétiques.The invention relates to a tool detection device or accessory for a machine, in particular for a handling trolley, wherein the device comprises a passive identification member integral with a tool or accessory and an active recognition means attached to the machine or handling trolley, in order to identify the tool or accessory for the proper functioning of their assembly, in which the recognition of the passive identification member by the active recognition means is a non-contact recognition, in which the passive identification member is a passive magnetic organ and the active recognition means is an active means of magnetic detection, characterized in that the passive magnetic member is a magnetic pattern member having a plurality of magnetic poles.

Sur la
Le chariot (1) à bras télescopique comporte un bras télescopique avec une extrémité distale (1a) appelée généralement par les hommes du métier «tête de flèche ».The carriage (1) with telescopic arm comprises a telescopic arm with a distal end (1a) generally called by the skilled person "arrow head".
La tête de flèche (1a) est destinée à être accouplée à un outil ou accessoire (2) par une conformation appropriée (2a) d'accouplement.The jib head (1a) is intended to be coupled to a tool or accessory (2) by a suitable conformation (2a) coupling.
Lorsque la tête de flèche (1a) et la conformation (2a) d'accouplement de l'outil ou accessoire (2) sont à proximité l'une de l'autre, un organe magnétique passif(2b) implanté au voisinage de la conformation d'accouplement (2a) est détecté par un moyen de reconnaissance (1b) implanté au voisinage ou sur la tête de flèche (1a).When the arrowhead (1a) and the coupling conformation (2a) of the tool or accessory (2) are in proximity to each other, a passive magnetic member (2b) implanted in the vicinity of the conformation coupling (2a) is detected by a recognition means (1b) implanted in the vicinity or on the jib head (1a).
Le moyen actif de reconnaissance (1b) est un moyen actif de reconnaissance sans contact.The active recognition means (1b) is an active means of non-contact recognition.
Le moyen actif de reconnaissance (1b) est de préférence un moyen actif de détection magnétique.The active recognition means (1b) is preferably an active means of magnetic detection.
Le moyen actif (1b) de détection magnétique peut comporter au moins un capteur à effet Hall, ou encore un capteur à technologie REED.The active magnetic detection means (1b) may comprise at least one Hall sensor, or a sensor with REED technology.
L'organe magnétique passif(2b) est de préférence un organe à motif magnétique comportant plusieurs pôles magnétiques distincts.The passive magnetic member (2b) is preferably a magnetic pattern member having a plurality of different magnetic poles.
Cet organe magnétique passif(2b) comporte de préférence un motif magnétique dont les extrémités sont polarisées, de manière à présenter une largeur d'identification ou de reconnaissance permettant le bon positionnement du moyen de reconnaissance (1b) par rapport à l'organe magnétique passif(2b).This passive magnetic member (2b) preferably comprises a magnetic pattern whose ends are polarized, so as to have an identification or recognition width allowing the correct positioning of the recognition means (1b) relative to the passive magnetic member (2b).
Sur la
Les barrettes d'extrémités correspondent à des pôles magnétiques polarisés, tandis que les quatre barrettes centrales peuvent être choisies dans le groupe comportant les pôles positifs, les pôles négatifs ou les pôles magnétiquement neutres.The end strips correspond to polarized magnetic poles, while the four central strips may be chosen from the group comprising the positive poles, the negative poles or the magnetically neutral poles.
Avantageusement, le motif magnétique défini par l'ensemble des barrettes A, B, C, D, E, F est un motif choisi dans un groupe évitant le risque d'inversion ou de confusion de motifs magnétiques.Advantageously, the magnetic pattern defined by the set of strips A, B, C, D, E, F is a pattern chosen in a group avoiding the risk of inversion or confusion of magnetic patterns.
Chaque outil ou accessoire est ainsi associé à un motif magnétique unique permettant de reconnaître sans erreur l'outil ou accessoire destiné à une utilisation particulière de la machine ou du chariot tout terrain correspondant.Each tool or accessory is thus associated with a unique magnetic pattern for recognizing without error the tool or accessory intended for a particular use of the machine or the corresponding off-road truck.
Sur la
L'invention n'est pas limitée à des motifs magnétiques à trois pôles magnétiques, mais s'étend au contraire à tout arrangement ou motif comportant une pluralité de pôles magnétiques agencés de manière linéaire, matricielle ou autre.The invention is not limited to magnetic patterns with three magnetic poles, but instead extends to any arrangement or pattern having a plurality of magnetic poles arranged linearly, matrix or otherwise.
Le pôle magnétique positif est repéré par le signe « + », le pôle magnétique négatif est repéré par le signe « - », et le pôle magnétique neutre est repéré par la lettre « N ».The positive magnetic pole is marked by the sign "+", the negative magnetic pole is marked by the sign "-", and the neutral magnetic pole is marked by the letter "N".
En utilisant tous les pôles magnétiques, il serait possible d'obtenir vingt-sept motifs différents.By using all the magnetic poles, it would be possible to obtain twenty-seven different patterns.
Pour éviter un risque d'inversion de motifs magnétiques, les motifs palindromiques qui correspondent à la lecture inversée d'un autre motif sont éliminés. Parmi les vingt-sept possibilités de motifs magnétiques on retire ainsi les trois motifs: « - + + », « - - + » et « - N + »,
qui sont des palindromes des motifs : « + + - », « + - -», et « + N - » .To avoid a risk of inversion of magnetic patterns, the palindromic patterns that correspond to the inverted reading of another pattern are eliminated. Among the twenty-seven possibilities of magnetic patterns are thus removed the three patterns: "- + +", "- - +" and "- N +",
which are palindromes of the motifs: "+ + -", "+ - -", and "+ N -".
Pour éviter un décentrage lors de la reconnaissance du motif, on élimine également tous les motifs dont une extrémité correspond à un pôle magnétique N neutre.To avoid misalignment during pattern recognition, all patterns whose one end corresponds to a neutral magnetic pole N are also eliminated.
L'élimination des motifs à extrémité correspondant à un pôle magnétique N neutre conduit ainsi à retirer quinze autres motifs.The elimination of end patterns corresponding to a neutral magnetic pole N thus leads to the removal of fifteen other patterns.
Finalement, après avoir retiré trois motifs palindromiques et quinze motifs à extrémité correspondant à un pôle magnétique N neutre, il reste neuf motifs permettant une identification fiable de l'outil ou de l'accessoire.Finally, after removing three palindromic patterns and fifteen end patterns corresponding to a neutral magnetic pole N, there remain nine reasons for reliable identification of the tool or accessory.
Une étude comparable effectuée par l'homme du métier conduira à conclure qu'un tableau similaire à quatre colonnes permettrait d'obtenir vingt-et-un motifs identifiants fiables composés de quatre pôles magnétiques ou barrettes répondant aux mêmes critères.A comparable study carried out by a person skilled in the art will lead to the conclusion that a similar table with four columns would make it possible to obtain twenty-one reliable identifying patterns composed of four magnetic poles or bars meeting the same criteria.
L'invention permet ainsi de déterminer de manière fiable, sans risque d'inversion de motif magnétique, l'identification d'un outil ou accessoire particulier destiné à une machine ou à un chariot de manutention.The invention thus makes it possible to reliably determine, without risk of inversion of magnetic pattern, the identification of a particular tool or accessory intended for a machine or a industrial truck.
Dans le cas d'un outil ou accessoire démuni d'organe d'identification passif, ou présentant un organe d'identification passif non reconnu, le dispositif comporte avantageusement un moyen de réglage par défaut de la machine ou du chariot de manutention, pour assurer de manière sûre et fiable le bon fonctionnement de leur assemblage.In the case of a tool or accessory that has no passive identification device, or has an unrecognized passive identification device, the device advantageously comprises a default adjustment means for the machine or the industrial truck, to ensure in a safe and reliable way the proper functioning of their assembly.
L'invention permet d'identifier les outils ou accessoires sans usure mécanique de l'organe magnétique passif ou du moyen actif de reconnaissance solidaire de la machine ou du chariot de manutention.The invention makes it possible to identify the tools or accessories without mechanical wear of the passive magnetic member or the active recognition means integral with the machine or the industrial truck.
Du fait que l'organe d'identification solidaire de l'outil ou de l'accessoire est un organe passif, il n'y a aucun besoin d'apport de puissance à l'outil ou à l'accessoire pour effectuer la reconnaissance de cet outil ou de cet accessoire.Because the integral identification member of the tool or accessory is a passive member, there is no need for power supply to the tool or accessory to perform the recognition of this tool or this accessory.
En outre, le choix des motifs magnétiques de l'organe d'identification passif permet de supprimer les erreurs en écartant les doublons ou palindromes, et permet également d'assurer un bon centrage du motif magnétique par rapport au moyen actif de reconnaissance, en assurant ainsi de manière sûre l'identification de l'outil ou de l'accessoire correspondant.In addition, the choice of magnetic patterns of the passive identification member makes it possible to eliminate errors by eliminating duplicates or palindromes, and also makes it possible to ensure a good centering of the magnetic pattern with respect to the active recognition means, by ensuring thus securely identifying the corresponding tool or accessory.
L'invention décrite en référence à des modes de réalisation particuliers ne leur est nullement limitée, mais couvre au contraire toute modification de forme et toute variante de réalisation dans le cadre des revendications annexées.The invention described with reference to particular embodiments is not in any way limited to them, but on the contrary covers any modification of form and any variant embodiment within the scope of the appended claims.
