La présente invention apporte justement une solution à ce problème.The present invention provides a solution to this problem.
Elle porte sur un dispositif de traitement de titres, en particulier de titres de transport comportant des informations magnétiques, du type comprenant :It relates to a device for processing tickets, in particular transport tickets comprising magnetic information, of the type comprising:
- au moins une tête d'inscription/lecture magnétique; - des moyens d'entraînement propres à entraîner au moins un titre devant la tête d'inscription/lecture magnétique; et- at least one magnetic writing / reading head; - drive means capable of driving at least one ticket in front of the magnetic writing / reading head; and

Selon une définition générale de l'invention, le dispositif comprend en outre un détecteur de pression monté sur l'organe presseur et propre à délivrer un signal proportionnel à la déformation dudit détecteur, ladite déformation étant fonction du déplacement de l'organe presseur provoqué par le passage d'un ou plusieurs titres.According to a general definition of the invention, the device further comprises a pressure detector mounted on the pressing member and capable of delivering a signal proportional to the deformation of said detector, said deformation being a function of the movement of the pressing member caused by the passage of one or more titles.
Ainsi, grâce à l'invention, il est possible de détecter les éventuels doubles de titres, sensiblement au moment de l'inscription/lecture magnétique du titre.Thus, thanks to the invention, it is possible to detect possible duplicates of titles, substantially at the time of magnetic entry / reading of the title.
Selon une caractéristique importante de l'invention, le détecteur de pression comprend une jauge de contrainte montée sur une lame de ressort en contact avec l'organe presseur, et des moyens de traitement sont propres à recevoir le signal délivré par la jauge, afin d'en déduire l'épaisseur et/ou le nombre de titres entraînés simultanément devant la tête d'inscription/lecture magnétique.According to an important characteristic of the invention, the pressure detector comprises a strain gauge mounted on a spring leaf in contact with the pressing member, and processing means are suitable for receiving the signal delivered by the gauge, in order to '' deduce the thickness and / or the number of titles simultaneously driven in front of the magnetic writing / reading head.

En pratique, un convertisseur analogique/numérique est propre à convertir le signal de sortie de l'amplificateur opérationnel en un signal numérique, et les moyens de traitement sont aptes à traiter ledit signal numérique ainsi converti afin d'en déduire l'épaisseur et/ou le nombre de titres entraînés simultanément devant la tête d'inscription/lecture magnétique. D'autres caractéristiques et avantages de l'invention apparaîtront à la lumière de la description détaillée ci- après et des dessins dans lesquels :In practice, an analog / digital converter is suitable for converting the output signal of the operational amplifier into a digital signal, and the processing means are capable of processing said digital signal thus converted in order to deduce therefrom and / or the number of titles simultaneously driven in front of the magnetic writing / reading head.

Les dessins annexés comportent à de nombreux titres des éléments de caractère certain. Ils pourront donc, non seulement servir à éclairer la description ci-après, mais aussi contribuer à la définition de l'invention, le cas échéant.The accompanying drawings contain elements of a certain character in many respects. They can therefore not only serve to clarify the description below, but also contribute to the definition of the invention, if necessary.
En référence à la figure 1, le dispositif de traitement de titres DIS, est par exemple celui décrit dans la Demande de Brevet déposée au nom de la Demanderesse, le même jour que la présente Demande, et sous le titre "Dispositif de traitement de titres à impression thermique et inscription/lecture magnétique selon un trajet interne en circuit fermé". A toutes fins utiles, une telle Demande de Brevet fait partie intégrante de la présente description.With reference to FIG. 1, the device for processing DIS titles is for example that described in the Patent Application filed in the name of the Applicant, on the same day as this Application, and under the title "Device for processing titles with thermal printing and magnetic writing / reading along an internal closed circuit path ". For all practical purposes, such a Patent Application forms an integral part of this description.
En bref, le dispositif de traitement de titres DIS comprend un poste d'introduction PIN, un poste de délivrance DEL, un poste d'inscription/lecture magnétique PIL et un poste d'impression thermique TT.In short, the title processing device DIS includes a PIN entry station, a DEL delivery station, a magnetic reading / writing station PIL and a thermal printing station TT.
La bande de titres est conduite devant un poste d'inscription/lecture magnétique PIL, comprenant une première tête d'inscription magnétique TMl, suivie d'une seconde tête TM2 , de lecture magnétique. En variante, le poste d'inscription/lecture magnétique PIL ne comprend qu'une seule tête magnétique. Dans ce cas, la bande défile plusieurs fois devant l'unique tête magnétique.The title strip is led to a magnetic writing / reading station PIL, comprising a first magnetic writing head TM1, followed by a second magnetic reading head TM2. Alternatively, the PIL magnetic read / write station only has one magnetic head. In this case, the strip passes several times in front of the single magnetic head.
Pour l'inscription/lecture magnétique bidirectionnelle, des moyens d'entraînement sont prévus pour être aptes à entraîner un titre selon un tronçon interne bidirectionnel, allant du poste d'introduction jusqu'à un poste de délivrance, via le poste d'inscription/lecture magnétique.For bidirectional magnetic writing / reading, drive means are provided to be capable of driving a ticket along a bidirectional internal section, going from the introduction station to a delivery station, via the registration station / magnetic reading.
En pratique, les moyens d'entraînement bidirectionnel (selon les sens F1-F2) comprennent une courroie Cl qui s'enroule sur des galets 4 et 6 via les têtes TMl et TM2, et s'enroule sur des galets 8 et 10 pour continuer le trajet interne. La courroie Cl est entraînée en circuit fermé grâce à un galet moteur 12, enroulé sur l'arbre moteur du moteur Ml.In practice, the bidirectional drive means (in the directions F1-F2) comprise a belt C1 which is wound on rollers 4 and 6 via the heads TM1 and TM2, and is wound on rollers 8 and 10 to continue the internal path. The belt C1 is driven in a closed circuit by means of a motor roller 12, wound on the motor shaft of the motor Ml.
Une fois que l'inscription magnétique des informations a été achevée sur un titre conservé, suivie de sa lecture immédia- te, la bande est conduite selon un canal de guidage CGI devant un poste de découpe COU.Once the magnetic writing of the information has been completed on a preserved title, followed by its immediate reading, the strip is led along a CGI guide channel in front of a COU cutting station.
En référence aux figures 2A et 2B, on retrouve le poste d'inscription/lecture magnétique PIL, avec sa ou ses têtes d'inscription/lecture magnétique TMl et TM2 et un organe presseur OP monté en regard de la ou des têtes d'inscription/lecture magnétique.With reference to FIGS. 2A and 2B, there is the magnetic writing / reading station PIL, with its magnetic writing / reading head (s) TMl and TM2 and a pressing device OP mounted opposite the writing head (s). / magnetic reading.
Un détecteur optique 111 est disposé en amont du poste d'inscription/lecture magnétique PIL, selon le sens FI. Le détecteur optique sert à synchroniser l'inscription/lecture magnétique et à initialiser la mesure d'épaisseur que l'on décrira plus en détail ci-après.An optical detector 111 is arranged upstream of the magnetic writing / reading station PIL, in the direction FI. The optical detector is used to synchronize the magnetic writing / reading and to initialize the thickness measurement which will be described in more detail below.
L'organe presseur OP comprend une surface d'appui 110 comprenant une lèvre d'entrée 112 et une lèvre de sortie 114. Les lèvres 112 et 114 sont recourbées vers l'extérieur du trajet du titre. La surface d'appui 110 est montée pivotante par rapport à un axe 116 perpendiculaire à la direction de défilement du titre à l'aide d'un levier 118 en forme de bras 119.The pressing member OP comprises a bearing surface 110 comprising an inlet lip 112 and an outlet lip 114. The lips 112 and 114 are curved towards the outside of the ticket path. The bearing surface 110 is pivotally mounted relative to an axis 116 perpendicular to the direction of scrolling of the title using a lever 118 in the form of an arm 119.
Selon l'invention, une jauge de contrainte 120 est montée sur un rappel élastique, ici une lame de ressort plane 122 dont l'extrémité libre 124 est en contact avec le levier 118. L'extrémité libre 124 de la lame de ressort 122 est avantageusement en forme de crochet dont la partie courbe 125 est en contact avec le bras du levier.According to the invention, a strain gauge 120 is mounted on an elastic return, here a flat spring leaf 122 whose free end 124 is in contact with the lever 118. The free end 124 of the spring leaf 122 is advantageously in the form of a hook, the curved part 125 of which is in contact with the arm of the lever.
La déformation de la jauge 120 est liée à la déformation de la partie plane de la lame ressort 122, elle-même fonction de la pression appliquée sur le bras 119 de levier 118, c'est«-à- dire la pression appliquée par le ou les titres sur la surface d'appui 110.The deformation of the gauge 120 is linked to the deformation of the flat part of the spring blade 122, itself a function of the pressure applied to the lever arm 119, that is to say the pressure applied by the or the titles on the support surface 110.
Des moyens de traitement 130 sont prévus pour recevoir le signal délivré par la jauge de contrainte 120 afin d'en déduire l'épaisseur et/ou le nombre de titres entraînés simultanément devant la tête d'inscription/lecture magnétique.Processing means 130 are provided for receiving the signal delivered by the strain gauge 120 in order to deduce therefrom the thickness and / or the number of titles simultaneously driven in front of the magnetic writing / reading head.
En référence à la figure 3, les moyens de traitement 130 comprennent un montage en pont de résistances RI , R2 et R3 propre à recevoir le signal délivré par la jauge de contrainte 120.With reference to FIG. 3, the processing means 130 comprise a bridge arrangement of resistors RI, R2 and R3 suitable for receiving the signal delivered by the strain gauge 120.
Un amplificateur opérationnel 132 reçoit les signaux issus du montage en pont de résistances RI, R2 et R3. Le montage en pont RI, R2 et R3 est du type "Wheatstone" dans lequel la jauge représente la quatrième valeur résistive.An operational amplifier 132 receives the signals from the bridge assembly of resistors RI, R2 and R3. The bridge assembly RI, R2 and R3 is of the "Wheatstone" type in which the gauge represents the fourth resistive value.
Cette quatrième valeur résistive varie en fonction de la déformation de la jauge. Les résistances RI, R2 et R3 sont réglées afin que le pont soit proche de l'équilibre dans les conditions normales de consigne.This fourth resistive value varies according to the deformation of the gauge. The resistors RI, R2 and R3 are adjusted so that the bridge is close to equilibrium under normal setpoint conditions.
Tout écart par rapport à ces conditions de consigne entraîne un déséquilibre du pont, lequel provoque une variation de la tension de sortie V de l'amplificateur différentiel 132. Cette tension est ensuite utilisée par les moyens de traitement afin d'en déduire une épaisseur et ainsi le nombre de titres entraînés simultanément devant la ou les têtes TMl et TM2. En numérique, un convertisseur analogique/numérique 134 convertit le signal de sortie V de l'amplificateur opérationnel 132 en un signal numérique.Any deviation from these setpoint conditions causes an imbalance of the bridge, which causes a variation in the output voltage V of the differential amplifier 132. This voltage is then used by the processing means in order to deduce therefrom a thickness and thus the number of titles driven simultaneously in front of the head or heads TM1 and TM2. In digital, an analog / digital converter 134 converts the output signal V of the operational amplifier 132 into a digital signal.
Des moyens de traitement numérique UC, par exemple selon un logiciel approprié, traitent le signal numérique ainsi converti, afin d'en déduire l'épaisseur du titre appliqué devant la tête d'inscription/lecture magnétique et déterminer ainsi les éventuels doubles ou triples.Digital processing means UC, for example according to an appropriate software, process the digital signal thus converted, in order to deduce therefrom the thickness of the title applied in front of the magnetic writing / reading head and thus determine any double or triple.
En pratique, le montage en pont de résistances RI, R2, R3 est agencé de telle sorte que le signal délivré par la jauge de contrainte en l'absence de titres de transport correspond à une valeur de repos.In practice, the mounting of resistors RI, R2, R3 is arranged in such a way that the signal delivered by the strain gauge in the absence of tickets corresponds to a rest value.
Le logiciel est adapté pour déduire de l'épaisseur ainsi détectée l'éventualité de passage simultané de 1, 2 ou 3 titres de transport devant la tête d'inscription/lecture magnétique.The software is adapted to deduce from the thickness thus detected the possibility of simultaneous passage of 1, 2 or 3 tickets in front of the magnetic recording / reading head.
Avantageusement, un procédé d'échantillonnage de la mesure d'épaisseur est prévu pendant l'inscription/lecture magnétique. Ce procédé consiste à acquérir l'épaisseur du titre à une fréquence choisie, par exemple tous les centimètres. Un traitement de ces échantillons permet d'éliminer les valeurs aberrantes de mesure pouvant être provoquées localement par les plis ou salissures des titres.Advantageously, a method for sampling the thickness measurement is provided during the magnetic writing / reading. This process consists in acquiring the thickness of the title at a chosen frequency, for example every centimeter. Processing these samples eliminates the outliers of measurement that can be caused locally by folds or soiling of the tickets.
Bien entendu, la présente invention n'est pas limitée au mode de réalisation décrit, mais s'étend au contraire à toute variante incluse dans le cadre des revendications ci-après. Of course, the present invention is not limited to the embodiment described, but on the contrary extends to any variant included within the scope of the claims below.
