Abstract
Description
L'invention concerne un dispositif de commande et de liaison sans contact pour équipements automatisés, notamment en machins-outils. The invention relates to a contactless control and connection device for automated equipment, in particular in machine tools.
L'objet de l'invention se rattache au secteur technique de la communication électrique. The object of the invention relates to the technical sector of electrical communication.
Les équipements automatisés, applicables notamment aux machines-outils, nécessitent de plus en plus une alimentation en éngergie électrique d'éléments amovibles déconnectables. Se pose également le problème d'assurer la transmission d'informations d 'entrées -sort ies eu égard à ces éléments. Automated equipment, applicable in particular to machine tools, increasingly requires a supply of electrical energy from removable disconnectable elements. There is also the problem of ensuring the transmission of input-output information with regard to these elements.
Par exemple, en cours de fabrication, ou en fin de fabrication, il est obligatoire de vérifier les caractéristiques dimensionnelles de la ou des pièces directement sur la machine-outil de par le degré d'automatisation atteint. Dans ce but, on dispose sur le porte-outil par exemple, une tête de mesure (palpeur) qui constitue l'élément amovible. Un tel élément étant actif, il est nécessaire de l'alimenter en énergie. For example, during manufacture, or at the end of manufacture, it is mandatory to check the dimensional characteristics of the part (s) directly on the machine tool due to the degree of automation achieved. For this purpose, there is on the tool holder for example, a measuring head (feeler) which constitutes the removable element. As such an element is active, it is necessary to supply it with energy.
Les connexions électriques automatiques proposées à ce jour, sont le plus souvent mal adaptées à l'environnement immédiat de la machine-outil en n'offrant pas toujours les garanties requises. il apparait également le prpblème de présentation automatique de deux éléments de prise pour assurer la connexion. The automatic electrical connections proposed to date are most often ill-suited to the immediate environment of the machine tool by not always offering the required guarantees. it also appears the problem of automatic presentation of two plug elements to ensure the connection.
Le dispositif selon l'invention s'est fixé pour but de résoudre ce problème d'une manière simple, rationnelle et efficace, en étant conformé pour transmettre à faible distance, la totalité ou l'une quelconque seulement des fonctions suivantes - l'énergie nécessaire à le ou les éléments amovibles décon nectablesmesureur ou autre) ; - les informations de commande nécessaires au(x) dit(s) élément(s) amovible(s) ; - les informations en provenance de cet ou ces éléments amovibles. The device according to the invention has set itself the aim of solving this problem in a simple, rational and effective manner, being configured to transmit at a short distance, all or just any of the following functions - energy necessary for the detachable removable element (s) or other measure); - the control information necessary for said removable element (s); - information from this or these removable elements.
A cet effet, le dispositif comprend, en combinaison, un coupleur inductif réalisé en deux parties mécaniquement distinctes, l'une! dés parties étant disposée sur l'élément support de base et reliée à une source d'énergie, l'autre partie étant disposée sur le ou les éléments amovibles et reliée à une chaîne de transmission d' informations établie à partir de modules complémentaires disposés respectivement sur le ou les éléments amovibles et l'élément support de base. To this end, the device comprises, in combination, an inductive coupler produced in two mechanically distinct parts, one! of the parts being arranged on the basic support element and connected to an energy source, the other part being arranged on the removable element or elements and connected to a chain of transmission of information established from complementary modules arranged respectively on the removable element (s) and the base support element.
Ces caractéristiques et d'autres encore ressortiront de la suite de la description. These characteristics and others will emerge from the following description.
Pour fixer l'objet de l'invention, sans toutefois le limiter, dans les dessins annexés
Les figures l et 2 montrent deux exemples de réalisation et d'appliéation du dispositif.To set the subject of the invention, without however limiting it, in the accompanying drawings
Figures 1 and 2 show two examples of embodiment and application of the device.
Afin de rendre plus concret l'objet de l'invention, on le décrit maintenant d'une manière non limitative en se référant aux exemples de réalisation des figures des dessins. In order to make the object of the invention more concrete, it is now described in a nonlimiting manner with reference to the exemplary embodiments of the figures of the drawings.
Le dispositif est conformé pour assurer, en combinai son le transport de 1 '-énerie nécessaire a t alimentation électrique du ou des éléments amovibles déconnectables.montés sur une partie de la machine et la transmission des informations recueillies par le ou lesdits éléments amovibles. Par élément amovible, on entend tout organe de mesure, quel que soit son type, tel que palpeur, capteur analogique... Sur les figures des dessins, ces éléments sont désignés dans leur ens-emble par (M). The device is shaped to ensure, in combination with the transport of the necessary energy for the electrical supply of the removable element or elements that can be disconnected. Mounted on a part of the machine and the transmission of the information collected by the said removable element or elements. The term “removable element” means any measuring member, whatever its type, such as a probe, analog sensor, etc. In the figures of the drawings, these elements are designated as a whole by (M).
Pour le transport de lénergie, le dispositif met en oeuvre un coupleur inductif (l)'constitué de deux parties magnétiques (la) et (lb) avec chacune un enroulement (2) et.(3). For the transport of energy, the device uses an inductive coupler (l) 'consisting of two magnetic parts (la) and (lb) each with a winding (2) and. (3).
Les deux parties (la) et (lb) sont disposées en regard en laissant subsister un léger entrefer (e). L'ensemble constitue donc un transformateur en deux parties (la) et (lb) mécaniquement distinctes se présentant par exemple sous la forme d'un tore magnétique. Le circuit magnétique (lb) est monté sur l'élément amovible (M), tandis que le circuit magnétique (la) est disposé sur la machine-outil proprement dite ou autre élément de base.The two parts (la) and (lb) are arranged opposite leaving a slight air gap (e). The assembly therefore constitutes a transformer into two mechanically distinct parts (la) and (lb), for example in the form of a magnetic toroid. The magnetic circuit (lb) is mounted on the removable element (M), while the magnetic circuit (la) is arranged on the machine tool itself or other basic element.
La transmission des informations en provenance du ou des éléments amovibles est établie à partir de modules complémentaires disposés respectivement sur le ou lesdits éléments amovibles et l'élément support de base. The transmission of information from the removable element (s) is established from complementary modules disposed respectively on the said removable element (s) and the basic support element.
Cette transmission s'opère par des liaisons optaélectroniques classiques à infra rouges. Une telle technologie est bien adaptée à une liaison numérique; plusieurs voies pouvant être disponibles dans chaque sens de transmission de sorte que par modulation du signal, il est possible de procéder à un contrôle du signal transmis, à une vérification de l' alimentation ou d'un bon fonctionnement... comme indiqué sur les figures ds dessins annexés. This transmission takes place via conventional optaelectronic infrared links. Such technology is well suited to a digital link; several channels may be available in each direction of transmission so that by modulating the signal, it is possible to carry out a control of the transmitted signal, a verification of the power supply or of proper operation ... as indicated on the figures of the attached drawings.
Dans ce but, l'enroulement primaire (2) du coupleur inductif (1) est relié à la source d'énergie par l'intermédiaire d'un circuit oscillateur (4). L'enroulement secondaire est relié notamment par l'intermédiaire d'un circuit redresseur et de filtrage (5), directement ou non à l'élément amovible (mesureur). For this purpose, the primary winding (2) of the inductive coupler (1) is connected to the energy source via an oscillator circuit (4). The secondary winding is connected in particular by means of a rectifier and filtering circuit (5), directly or not to the removable element (measurer).
Dans l'exemple de la figure 1, l'élément de base reçoit un ou des oscillateurs de commande de transmission avec un ou des circuits de modulation (6) pour agir-sur un ou des émetteurs à infra rouges (7a) d'un coupleur optoélectronique. Le ou les récepteurs infra rouges correspondants (7b), placés sur l'élément amovible, sont asservis à des circuits démodulateurs et de contrôle (8) pour vérifier que la transmission s'effectue bien. Il est aussi possible de sélectionner l'un ou plusieurs des mesureurs(Ba)-
Les signaux captés, éventuellement mis en forme par un circuit adaptateur (9), passent dans un circuit modulateur (10), pour être transmis par des émetteurs infrarouges (il). In the example of FIG. 1, the basic element receives one or more transmission control oscillators with one or more modulation circuits (6) to act on one or more infrared emitters (7a) of a optoelectronic coupler. The corresponding infrared receiver (s) (7b), placed on the removable element, are slaved to demodulator and control circuits (8) to verify that the transmission is taking place. It is also possible to select one or more of the meters (Ba) -
The received signals, possibly shaped by an adapter circuit (9), pass through a modulator circuit (10), to be transmitted by infrared transmitters (il).
Les récepteurs infra rouges correspondants tllb) avec démodulateurs (12) et circuits de contrôles (13), sont disposés sur l'élément de base.The corresponding infrared receivers tllb) with demodulators (12) and control circuits (13) are arranged on the basic element.
Dans l'exemple de la figure 2, où la transmission d' informations s'effectue d'une manière analogique, à la sortie de l'élément amovible (capteur (14)] sont montés un convertisseur tension-fréquence (15) correspondant au signal relevé et un convertisseur tension-fréquence (16) correspondant à une tension de référence assurant ainsi un contrôle supplémentaire. In the example of FIG. 2, where the transmission of information takes place in an analog manner, at the output of the removable element (sensor (14)] are mounted a voltage-frequency converter (15) corresponding to the signal detected and a voltage-frequency converter (16) corresponding to a reference voltage thus ensuring additional control.
Chacun des convertisseurs (15) et (16) est asservi à un coupleur opto-électronique (17) et (18) dont les émetteurs (17a) (-18a) sont disposés sur l'élément amovible, tandis que le récepteur (l7b) - (18b) sont placés sur l'élément support de base.Each of the converters (15) and (16) is slaved to an opto-electronic coupler (17) and (18) whose transmitters (17a) (-18a) are arranged on the removable element, while the receiver (l7b) - (18b) are placed on the basic support element.
Il est possible d'exploiter les signaux directement à la sortie des récepteurs (l7b) - (l8b) selon les applications spécifiques désirées ou bien après avoir procédé à une convertion fréquence-tension.par des convertisseurs (19) - (20). It is possible to use the signals directly at the output of the receivers (l7b) - (l8b) according to the specific applications desired or after having carried out a frequency-voltage conversion by converters (19) - (20).
I1 est bien évident que les caractéristiques de chacun des deux circuits magnétiques (la) et (lob) du coupleur inductif (1) ainsi que le nombre de spires des enroulements pri- maire et secondaire (2) et (3) sont fonction des applications recherchées . It is obvious that the characteristics of each of the two magnetic circuits (la) and (lob) of the inductive coupler (1) as well as the number of turns of the primary and secondary windings (2) and (3) depend on the applications. wanted.
A noter que plusieurs éléments amovibles peuvent être alternativement connectés à une même baste et inversement. Note that several removable elements can be alternately connected to the same baste and vice versa.
on prévoit dans une autre forme de réalisation d' effectuer la transmission d'informations par liaisons à coupleurs inductifs ;une- telle technologie étant mieux adaptée à la transmission d'un signal analogique en modulation de ré- quence. in another embodiment, provision is made for transmitting information via links with inductive couplers, such technology being better suited to transmitting an analog signal in frequency modulation.
L'invention ne se limite aucunement à celui de ses modes d'application ndn plus qu'à ceux des modes de réalisation de ses diverses parties ayant plus spécialement été indiquées elle en embrasse au contraire toutes les variantes. The invention is in no way limited to that of its modes of application ndn more than to those of the embodiments of its various parts having been more especially indicated, on the contrary it embraces all variants.
