Description

L'invention se rapport aux sélecteurs de pièces de monnaie qui sont généralement intégrés dans des appareils ou machines à paiement par pièces.The invention relates to coin selectors which are generally integrated in coin-operated apparatus or machines.

Habituellement, les pièces d'un type donné sont sélectionnées en premier par les caractéristiques dimensionnelles maximales qu'impose la fente d'introduction des pièces dans l'appareil.Usually, the parts of a given type are selected first by the maximum dimensional characteristics imposed by the slot for inserting the parts into the device.

Il est connu d'ajouter à ce critère une identification complémentaire, par exemple à l'aide d'un capteur sensible au poids de chaque pièce ou d'un capteur de type inductif pour tester, à l'aide d'un circuit électrique approprié, une caractéristique électromagnétique de la pièce.It is known to add to this criterion an additional identification, for example using a sensor sensitive to the weight of each part or an inductive type sensor for testing, using an appropriate electrical circuit. , an electromagnetic characteristic of the part.

La satisfaction de ces différentes exigences conduit à une réalisation constructive très dépendante des pièces particulières à traiter, et qui implique des adaptations relativement complexes du matériel en cas de changement du type de pièce accepté ou selon les pays dans lesquels il est appelé à être utilisé. De plus, la fiabilité d'un sélecteur reposant sur les seuls critères précités laisse encore à désirer.The satisfaction of these different requirements leads to a constructive realization very dependent on the particular parts to be treated, and which implies relatively complex adaptations of the material in the event of change of the type of part accepted or according to the countries in which it is called to be used. In addition, the reliability of a selector based solely on the aforementioned criteria still leaves something to be desired.

La présente invention a pour objet un nouveau sélecteur de monnaie pouvant être qualifié de multipièces en ce qu'il est d'une conception propre à recevoir et à identifier diverses sortes de pièces sans modification de sa structure et de ses capteurs de caractéristique des pièces, et à partir duquel il suffit de comparer des résultats de mesure à des données mémorisées d'identification des seules pièces que l'on se propose d'accepter. Ainsi, l'adaptation d'un tel sélecteur à des changements de monnaie ou aux monnaies de divers pays ne nécessitera qu'un simple changement de données mémorisées relatives aux pièces dont l'acceptation est préalablement choisie.The present invention relates to a new currency selector which can be qualified as multi-room in that it is of a design suitable for receiving and identifying various kinds of coins without modifying its structure and its coin characteristic sensors, and from which it suffices to compare measurement results with memorized identification data of the only parts which it is proposed to accept. Thus, the adaptation of such a selector to changes of currency or to the currencies of various countries will require only a simple change of stored data relating to the coins whose acceptance is previously chosen.

L'invention conduit en outre avantageusement à un sélecteur de réalisation intrinsèque simple, d'encombrement réduit, et fonctionnant en une position statique des pièces et selon un principe qui lui confère une fiabilité intéressante en ce domaine.The invention also advantageously leads to a selector of simple intrinsic embodiment, of reduced bulk, and operating in a static position of the parts and according to a principle which gives it an advantageous reliability in this field.

Essentiellement, à cet effet, le sélecteur de pièces de monnaie selon l'invention, dans lequel les pièces sont amenées en position statique en présence d'au moins un capteur d'identification d'une caractéristique de chaque pièce, est caractérisé en ce qu'il fait appel, aux fins d'identification d'au moins une caractéristique dimensionnelle d'au moins un type de pièce, à un capteur capacitif dans lequel la pièce en position statique constitue l'une des plaques d'au moins un condensateur dont la mesure de capacité est représentative de la caractéristique correspondante de chaque pièce à identifier.Essentially, for this purpose, the coin selector according to the invention, in which the coins are brought into static position in the presence of at least one sensor for identifying a characteristic of each coin, is characterized in that '' it uses, for the purposes of identifying at least one dimensional characteristic of at least one type of part, a capacitive sensor in which the part in static position constitutes one of the plates of at least one capacitor, the capacity measurement is representative of the corresponding characteristic of each part to be identified.

Suivant une réalisation préférée, un tel sélecteur comporte au moins deux plaques de capteur capacitif différentes disposées de part et d'autre de la position statique d'identification des pièces, l'une des plaques étant de plus grande surface en regard de la pièce de plus grand diamètre à identifier pour évaluer la caractéristique de diamètre correspondante de chaque pièce, l'autre plaque étant de plus petite surface que la pièce de plus petit diamètre à identifier pour évaluer la caractéristique d'épaisseur de chaque pièce.According to a preferred embodiment, such a selector comprises at least two different capacitive sensor plates disposed on either side of the static position for identifying the parts, one of the plates being of larger surface facing the part of larger diameter to be identified in order to evaluate the corresponding diameter characteristic of each part, the other plate being of smaller area than the part of smaller diameter to be identified in order to evaluate the thickness characteristic of each part.

A cette disposition compacte de capteurs de caractéristiques dimensionnelles peut en outre être aisément intégré, aux fins d'identification d'une caractéristique électromagnétique de matière de chaque pièce, un capteur inductif disposé à l'intérieur de la plaque du capteur capacitif précité de plus grande surface, ce capteur inductif ayant une dimension frontale inférieure à celle de la pièce de plus petit diamètre à identifier.In addition to this compact arrangement of dimensional characteristic sensors, an inductive sensor arranged inside the plate of the aforementioned capacitive sensor plate can easily be integrated, for the purpose of identifying an electromagnetic characteristic of the material of each part. surface, this inductive sensor having a front dimension smaller than that of the smallest diameter part to be identified.

Pour accroître la fiabilité des mesures capacitives appelées à être effectuées, il peut en outre être associé à un tel sélecteur, à l'écart du ou des capteurs capacitifs, une capacité témoin de tarage des mesures faites, utilisable pour -ompenser les variations d'ambiance susceptibles d'influer sur le résultat desdites mesures.To increase the reliability of the capacitive measurements called to be carried out, it can also be associated with such a selector, apart from the capacitive sensor (s), a control capacity for taring the measurements made, usable for compensating for variations in atmosphere likely to influence the result of said measurements.

Une forme de réalisation d'un sélecteur de pièces de monnaie selon l'invention est d'ailleurs ci-après décrite, à titre d'exemple non limitatif, et en référence au dessin annexé dans lequel :

  • la fig. 1 est une vue en coupe transversale du sélecteur au niveau du poste d'idenfication à capteurs multiples, suivant la ligne I-I de la fig. 2;
  • la fig. 2 est une vue de détail de côté du poste d'identification, suivant II-II de la fig. 1.
An embodiment of a coin selector according to the invention is furthermore described below, by way of nonlimiting example, and with reference to the appended drawing in which:
  • fig. 1 is a cross-sectional view of the selector at the multiple sensor identification station, along line II of FIG. 2;
  • fig. 2 is a detail side view of the identification station, along II-II of FIG. 1.

Le sélecteur représenté comprend deux platines parallèles 1 et 2 en matière électriquement non conductrice, maintenues assemblées entre elles avec un espacement donné, par l'intermédiaire d'entretoises 3, dans lesquelles sont engagées des vis de maintien des platines non représentées.The selector shown comprises two parallel plates 1 and 2 made of electrically non-conductive material, kept assembled together with a given spacing, by means of spacers 3, in which screws for holding the plates, not shown, are engaged.

La platine 1 est pourvue sur sa face en regard de l'autre platine d'un trottoir 4 de circulation des pièces, telle que la pièce P de la fig. 1, ce trottoir étant constitué par l'essentiel sous forme d'une piste rapportée et inclinée par rapport à l'horizontale pour amener toute pièce introduite dans le sélecteur suivant la flèche E, à rouler jusqu'en une position d'arrêt pour identification contre une barrière 5. Cette barrière est prévue mobile transversalement par rapport aux platines et soumise à des moyens d'effacement et de rappel en position d'arrêt pouvant être quelconques et ici non représentée. On doit de même comprendre que chaque pièce est amenée en position sur le trottoir après être passée au travers d'une fente de guidage non représentée de l'appareil, de gabarit au moins égal aux plus grandes dimensions de pièces d'utilisation envisagée.The plate 1 is provided on its face opposite the other plate with a sidewalk 4 for circulation of the parts, such as the part P of FIG. 1, this sidewalk being essentially constituted in the form of an attached track and inclined with respect to the horizontal in order to bring any part introduced into the selector according to arrow E, to roll to a stopped position for identification against a barrier 5. This barrier is provided movable transversely with respect to the plates and subjected to means for erasing and returning to the stopped position which may be any and here not shown. It should also be understood that each piece is brought into position on the sidewalk after having passed through a not shown guide slot of the device, of size at least equal to the largest dimensions of pieces of intended use.

Comme cela apparaît à la fig. 1, les platines 1 et 2 sont montées avec une certaine inclinaison par rapport à la verticale, . de sorte que toute pièce amenée sur le trottoir 4 s'appuie latéralement en position stable contre la platine 1 tout en descendant la pente inclinée du trottoir jusqu'à sa position d'arrêt. Dans cette dernière position, la pièce repose sur une portion 4a de trottoir constituée sous forme d'un segment électriquement conducteur. On a représenté à la fig. 2, à titre illustratif, d'une part en trait plein un contour d'une pièce Pm de diamètre maximal accepté et, d'autre part en trait mixte, un contour d'une autre pièce Pp du diamètre minimal accepté, toutes deux en leur position d'arrêt normal contre la barrière 5 qui est leur position statique d'identification. Sur la face externe de la platine 1, est collée une plaque conductrice P1 conformée et disposée de façon à être enveloppante de la plus grande pièce Pm en sa position statique, telle qu'elle est vue dans la fig. 2.As shown in fig. 1, the plates 1 and 2 are mounted with a certain inclination relative to the vertical,. so that any part brought to the sidewalk 4 bears laterally in a stable position against the plate 1 while descending the inclined slope of the sidewalk to its stopped position. In this latter position, the part rests on a sidewalk portion 4a formed in the form of an electrically conductive segment. There is shown in FIG. 2, by way of illustration, on the one hand in solid line an outline of a part Pm of maximum accepted diameter and, on the other hand in phantom, an outline of another part Pp of the minimum accepted diameter, both in their normal stop position against the barrier 5 which is their static identification position. On the external face of the plate 1, a conductive plate P1 is stuck shaped and arranged so as to be enveloping the largest part Pm in its static position, as seen in FIG. 2.

Sur la face interne de la platine 2 est collée une plaque conductrice P2 conformée et disposée de façon à se trouver dans l'enveloppe de la plus petite pièce Pp en sa position statique, telle qu'elle est vue dans la fig. 2.On the internal face of the plate 2 is bonded a conductive plate P2 shaped and arranged so as to be in the envelope of the smallest part Pp in its static position, as seen in FIG. 2.

Les plaques P1 et P2 définissent ainsi avec toute pièce P arrêtée en position statique, les deux plaques de deux capteurs capacitifs, et elles sont respectivement destinées à être reliées électriquement à un circuit de mesure de capacité passant par le segment conducteur 4a du trottoir et la pièce P en tant que seconde plaque de chaque capteur capacitif ainsi constitué. On peut déjà comprendre qu'un tel sélecteur permet d'obtenir, par mesure de la capacité entre la plaque P1 et la pièce P à identifier une caractéristique représentative de la surface de la plaque constituée par la pièce P considérée, et qui est donc fonction du diamètre de cette dernière, compte tenu de l'épaisseur constante de la platine 1 en tant que diélectrique.The plates P1 and P2 thus define, with any part P stopped in the static position, the two plates of two capacitive sensors, and they are respectively intended to be electrically connected to a capacity measurement circuit passing through the conductive segment 4a of the pavement and the piece P as the second plate of each capacitive sensor thus formed. We can already understand that such a selector makes it possible to obtain, by measuring the capacity between the plate P1 and the part P to identify a characteristic representative of the surface of the plate constituted by the part P considered, and which is therefore a function the diameter of the latter, taking into account the constant thickness of the plate 1 as a dielectric.

Il est à voir aussi que dans le capteur capacitif constitué par la pièce P considérée avec la plaque P2, la mesure de la capacité correspondante constitue une caractéristique représentative de l'intervalle résiduel e existant entre la pièce P considérée et la plaque P2, et qu'elle est donc fonction de l'épaisseur de la pièce à identifier.It should also be seen that in the capacitive sensor constituted by the part P considered with the plate P2, the measurement of the corresponding capacity constitutes a characteristic representative of the residual interval e existing between the part P considered and the plate P2, and that 'It is therefore a function of the thickness of the part to be identified.

Dans les limites de l'enveloppe précitée définie par la plus petite pièce Pp, telle que vue à la fig. 2, il est en outre ici disposé dans la platine 1, un capteur inductif CI. Ce dernier est constitué par une carcasse de ferrite 6 à section en E affleurant le plan de la face interne de la platine, et dans laquelle est logée une bobine 7 destinée à être raccordée à un circuit de mesure de l'inductance de cette bobine, laquelle est fonction de la fermeture du circuit magnétique de la carcasse 6 qu'assure la pièce P à identifier dans la position statique prédéfinie. Cette mesure est ainsi représentative d'une caractéristique électromagnétique de matière de chaque pièce.Within the limits of the aforementioned envelope defined by the smallest part Pp, as seen in FIG. 2, it is further here arranged in the plate 1, an inductive sensor CI. The latter consists of a ferrite carcass 6 with an E-section flush with the plane of the internal face of the plate, and in which is housed a coil 7 intended to be connected to a circuit for measuring the inductance of this coil, which is a function of the closure of the magnetic circuit of the carcass 6 which the part P to be identified ensures in the predefined static position. This measurement is thus representative of an electromagnetic characteristic of the material of each part.

Les platines isolantes 1 et 2 peuvent servir de support de circuit imprimé pour les circuits de mesures capacitives prévues, une platine supplémentaire isolante 8 étant ici prévue comme support du capteur inductif CI et pouvant porter un circuit imprimé de mesure correspondant.The insulating plates 1 and 2 can serve as a printed circuit support for the capacitive measurement circuits provided, an additional insulating plate 8 being here provided as a support for the inductive sensor CI and can carry a corresponding measurement circuit.

Il est entendu que tant les circuits de mesure capacitives que celui de mesure d'inductance peuvent être de tout type connu ou approprié pour de telles mesures, au choix de l'homme de l'art.It is understood that both the capacitive measurement circuits and that of the inductance measurement can be of any known or appropriate type for such measurements, at the choice of a person skilled in the art.

En outre, afin de pouvoir introduire dans les mesures capacitives faites une correction des conditions d'ambiance du sélecteur, il est également ici prévu, à l'écart mais au voisinage des capteurs capacitifs, sur les platines 1 et 2, deux plaques conductrices, telle que celle 9 de la platine 1, constitutives d'une capacité témoin de tarage, permettant ainsi de procéder à des mesures capacitives relatives échappant aux variations des conditions d'ambiance.In addition, in order to be able to introduce into the capacitive measurements a correction of the ambient conditions of the selector, there is also provided here, apart but in the vicinity of the capacitive sensors, on the plates 1 and 2, two conductive plates, such as that 9 of the plate 1, constituting a calibration calibration capacity, thus making it possible to carry out relative capacitive measurements escaping from variations in the ambient conditions.

On comprendra qu'on peut ainsi dans ce cas établir dans un bref intervalle de temps d'arrêt de chaque pièce, deux mesures dimensionnelles de diamètre et d'épaisseur ainsi que d'une caractéristique électromagnétique, permettant d'identifier par leur combinaison, de façon fiable, et avec un sélecteur simple et de faible encombrement au niveau de ces capteurs, toutes sortes de pièces. Il suffit simplement, comme déjà évoqué, pour adapter un appareil à toute monnaie désirée, de changer au niveau des circuits électroniques d'exploitation, des données mémorisées destinées à être comparées aux résultats des mesures faites, pour déterminer si les caractéristiques correspondantes des pièces testées sont celles des bonnes pièces ou de pièces à refuser.It will be understood that in this case it is thus possible to establish, in a brief interval of stopping time for each part, two dimensional measurements of diameter and thickness as well as of an electromagnetic characteristic, making it possible to identify by their combination, reliably, and with a simple selector and compact on these sensors, all kinds of parts. It suffices simply, as already mentioned, to adapt a device to any desired currency, to change at the level of the electronic operating circuits, stored data intended to be compared with the results of the measurements made, to determine whether the corresponding characteristics of the coins tested are those of good parts or parts to refuse.

Par exemple, après ces mesures, la barrière 5 peut être effacée temporairement pour laisser la pièce testée continuer vers un aiguillage d'acceptation ou de refus actionnable en fonction de l'exploitation des résultats de mesure.For example, after these measurements, the barrier 5 can be temporarily erased to allow the tested part to continue towards an acceptance or refusal switch which can be actuated as a function of the exploitation of the measurement results.

Ou encore, la barrière 5 peut être prévue comme barrière effaçable pour la seule acceptation des pièces, tandis qu'une partie du trottoir 4 et la portion 4a de celui-ci peuvent être précises en tant qu'éléments effaçables transversalement à la platine 1, à l'effet de remplir la fonction de rejet des pièces non acceptées vers une sébille correspondante.Or again, the barrier 5 can be provided as an erasable barrier for the sole acceptance of the coins, while a part of the sidewalk 4 and the portion 4a thereof can be precise as elements which can be erased transversely to the plate 1, in order to fulfill the function of rejecting parts that are not accepted to a corresponding waste.

Cette ou ces fonctions d'effacement peuvent être combinées de manière connue à une fonction de triage ne laissant venir les pièces qu'une à une au poste d'identification, et le cycle de mesure peut être déclenché en réponse à toute détection de présence de pièces assurée d'une manière quelconque connue (par contact de présence ou détection photoélectrique par exemple), étant à voir que toutes ces dispositions de manutention des pièces peuvent recevoir de nombreuses solutions ou variantes dans le cadre des principes d'identification des pièces et de construction du sélecteur faisant particulièrement l'objet de la présente invention et venant d'être décrits.This or these erasing functions can be combined in a known manner with a sorting function leaving the pieces coming one by one to the identification station, and the measurement cycle can be triggered in response to any detection of the presence of parts provided in any known manner (by presence contact or photoelectric detection for example), being that all of these parts handling arrangements can receive many solutions or variants within the framework of the principles of identification of parts and construction of the selector which is particularly the subject of the present invention and which has just been described.
