Abstract

The container return centre makes use of redundancy in the marking of the container to improve identification. The reader uses logic 'OR' processing of multiple scans, and the scans are made at two or more reading sites. The two sites are preferably diametrically opposed, each fitted with a pair of light or infra-red emitters and detectors. The detectors control operation of a pair of jaws, which allow a rejected container to fall into a reject handler. Accepted containers are carried away on an automated conveyor, and a signal given to dispense the return value of the container.

Description

DOMAINE DE L'INVENTIONFIELD OF THE INVENTION

L'invention concerne un appareil permettant la déconsignation d'un contenant rigide ou non de produits liquides ou solides dont l'identification est assurée par la reconnaissance d'un marquage déterminé de ce contenant consigné.The invention relates to an apparatus for withdrawal of rigid or non-rigid container of products liquids or solids whose identification is ensured by the recognition of a specific marking of this container recorded.

ART ANTERIEURPRIOR ART

La récupération, à des fins de recyclage ou non, des contenants de produits liquides ou solides, une fois ces produits consommés, constitue un enjeu important pour le respect de l'environnement.The recovery, for recycling or not, of containers of liquid or solid products, once these products consumed, is an important issue for the respect the environment.

Pour pallier au manque de discipline de certains consommateurs de ces produits, le principe de la consignation du contenant s'est révélé efficace.To compensate for the lack of discipline of some consumers of these products, the principle of Returning the container has been shown to be effective.

Toutefois, l'efficacité de ce principe se trouve totalement subordonnée à celle de la déconsignation c'est-à-dire à la restitution d'une contre-valeur, notamment monétaire, lors de la récupération du contenant. Pour favoriser le développement du réflexe de restitution du contenant vide chez le consommateur, des dispositifs automatiques de déconsignation ont été mis au point.However, the effectiveness of this principle is found totally subordinated to that of the deconsignation that is to say the return of a consideration, in particular monetary, when recovering the container. For favor the development of the restitution reflex of the empty container at the consumer, devices automatic termination codes have been developed.

Ceux-ci sont particulièrement adaptés à la récupération de gobelets délivrés par les distributeurs automatiques de boissons.These are particularly suitable for recovery cups delivered by the vending machines of drinks.

Le brevet français n° 2.580.418 mentionne l'utilisation d'un dispositif de détection de la présence d'un marquage sur un gobelet pour l'identifier et restituer une contrevaleur. Ce brevet, d'ailleurs abandonné, ne propose aucun mode de réalisation de ce dispositif de détection.French Patent No. 2,580,418 mentions the use a device for detecting the presence of a marking on a goblet to identify it and restore a value. This patent, which was also abandoned, does not offer any embodiment of this detection device.

Les brevets français nos. 2.618.239 et 2.656.942 décrivent un dispositif d'identification de gobelets par la reconnaissance d'une forme déterminée. L'exploitation de ce dispositif a révélé plusieurs inconvénients. En effet, ce type de reconnaissance :

  • augmente de façon significative le prix de revient du gobelet en imposant la fabrication de récipients de forme non standard;
  • ne permet pas une distinction suffisamment précise de l'origine du gobelet et peut entraíner la restitution de consignes pour des gobelets provenant d'un autre appareil de distribution.
French patents nos. 2,618,239 and 2,656,942 describe a device for identifying cups by recognizing a specific shape. The exploitation of this device revealed several drawbacks. Indeed, this type of recognition:
  • significantly increases the cost price of the cup by requiring the manufacture of non-standard shaped containers;
  • does not allow a sufficiently precise distinction of the origin of the cup and may result in the return of instructions for cups from another dispensing device.

Le brevet WO 93/03461 décrit un dispositif de contrôle de signes d'identification de gobelets. Celui-ci capte et évalue grâce à un barrage photoélectrique une lumière réfléchie caractéristique des signes d'identification.WO 93/03461 describes a control device of identification signs for cups. This picks up and uses a light barrier to evaluate a light thoughtful characteristic of identification signs.

Toutefois, le dispositif de lecture, placé trop près du gobelet à identifier fournit des résultats insuffisamment fiables. En effet, le barrage photoélectrique ainsi disposé est très facilement souillé.However, the reading device, placed too close to the cup to be identified provides insufficient results reliable. Indeed, the light barrier thus arranged is very easily soiled.

Le brevet français n° 2.645.305 décrit un système de reconnaissance par un moyen optoélectronique.French Patent No. 2,645,305 describes a system of recognition by optoelectronic means.

Le brevet français n° 2.631.477 décrit un système de reconnaissance du gobelet par dépression.French Patent No. 2,631,477 describes a system of recognition of the cup by depression.

Le brevet US 4.316.533 décrit un dispositif de récupération de contenants vides engendrant la délivrance d'une contre-valeur. Les contenants marqués sont identifiés par la lecture de cette marque à l'aide d'une émission ultraviolette qui, lorsqu'elle rencontre la marque, donne naissance à une émission fluorescente.US Patent 4,316,533 describes a device for recovery of empty containers leading to delivery of a counter value. The marked containers are identified by reading this mark using a program ultraviolet which, when it meets the mark, gives birth of a fluorescent emission.

Le brevet US 4.248.334 décrit un appareil de recyclage dans lequel un lecteur identifie la réflexion d'un rayon laser par un marquage réalisé sur le récipient.US Patent 4,248,334 describes a recycling device in which a reader identifies the reflection of a ray laser by a marking made on the container.

Le brevet US 4.248.389 décrit un dispositif de tri de divers types de récipient. L'identification de ces types de récipient est assurée par un lecteur optique (dont les caractéristiques techniques ne sont pas développées dans ce document).US Patent 4,248,389 describes a sorting device for various types of container. Identifying these types of container is provided by an optical reader (whose technical characteristics are not developed in this document).

La diversité des inventions réalisées dans le domaine de la récupération des contenants de produits montre l'intérêt économique de ces dispositifs. The diversity of inventions made in the field recovery of watch product containers the economic interest of these devices.

Toutefois, les inventions déjà réalisées présentent une fiabilité limitée dans la mesure où leurs systèmes d'identification du type ou de l'origine du contenant ne tiennent compte ni de la souillure ou la détérioration partielle du marquage ou des cellules de lecture, ni de la lecture au niveau de la surcouche du marquage du contenant.However, the inventions already made have a limited reliability as their systems identifying the type or origin of the container take into account neither the stain or deterioration partial marking or reading cells, nor the reading on the overlay of the container marking.

Un objet de la présente invention est un appareil de déconsignation d'un contenant dont la fiabilité de l'identification est sensiblement augmentée par redondance de la lecture du marquage.An object of the present invention is an apparatus for withdrawal of a container whose reliability identification is significantly increased by redundancy reading the marking.

Un autre objet de la présente invention est un appareil de déconsignation d'un contenant capable d'assurer une lecture suffisamment fine pour lire avec une grande précision un marquage relativement complexe et donc difficilement falsifiable.Another object of the present invention is an apparatus of disconnection of a container capable of ensuring a reading fine enough to read with great precision a relatively complex marking and therefore hardly falsifiable.

Un autre objet de la présente invention est un appareil de déconsignation d'un contenant présentant un dispositif de sécurité permettant la délivrance de la consigne uniquement après la chute du contenant dans un réceptacle déterminé, évitant ainsi les multiples restitutions de consignes pour un même contenant.Another object of the present invention is an apparatus of disconnection of a container presenting a device for security allowing the delivery of the deposit only after the container has fallen into a specific receptacle, thus avoiding multiple restitution of instructions for the same container.

BREVE DESCRIPTION DE L'INVENTIONBRIEF DESCRIPTION OF THE INVENTION

L'invention concerne un appareil de déconsignation d'un contenant rigide ou non de produits liquides ou solides.The invention relates to a device for deconsigning a whether or not rigidly containing liquid or solid products.

Toutefois, l'invention peut être exploitée pour tout type d'objet susceptible de porter une marque pouvant être lue par le dispositif décrit ci-dessous.However, the invention can be used for any type of object likely to bear a mark which can be read by the device described below.

L'appareil, selon l'invention, est construit de manière à assurer tout ou partie des étapes suivantes :

  • introduction du contenant;
  • détection de la présence du contenant;
  • lecture du marquage;
  • comparaison du code obtenu par la lecture du marquage avec un code de référence à l'aide d'une carte électronique pouvant contenir un microprocesseur;
  • choix de la déconsignation ou de la non déconsignation;
  • chute du contenant dans un réceptacle;
  • contrôle du bon cheminement du contenant;
  • le cas échéant, restitution de la consigne.
The device according to the invention is constructed so as to carry out all or part of the following steps:
  • introduction of the container;
  • detection of the presence of the container;
  • reading the marking;
  • comparison of the code obtained by reading the marking with a reference code using an electronic card which may contain a microprocessor;
  • choice of termination or non-termination;
  • dropping the container into a receptacle;
  • control of the correct progress of the container;
  • if necessary, return of the deposit.

Le marquage graphique ou sérigraphique est effectué sur le contenant avec une encre alimentaire conductrice ou non par un procédé connu.Graphic or screen printing is carried out on the container with a conductive or non-conductive food ink by a known method.

Le perfectionnement du dispositif d'identification du marquage selon l'invention est constitué par redondance de la lecture de ce marquage.Improvement of the device for identifying the marking according to the invention consists of redundancy of reading this marking.

Il peut, par exemple, être mis en oeuvre en dotant l'appareil de déconsignation d'au moins deux sites de lecture. La pluralité de ces sites permet d'éviter les erreurs de lecture, et donc les non restitutions de consignes pour des produits normalement consignés, provoquées par des souillures, salissures, détériorations partielles, etc. du marquage d'identification ou du dispositif de lecture. Les signaux correspondants à la lecture du marquage sont alors traités par une fonction logique, par exemple « ou » inclusif. Dans le cas du traitement par une fonction logique « ou » inclusif, la reconnaissance du marquage par un seul site de lecture entraíne donc la restitution de la consigne. Le deuxième site, et éventuellement les suivants, constituent donc en quelque sorte des sites de vérification de la conformité du marquage.It can, for example, be implemented by providing the deconsignation device of at least two reading. The plurality of these sites makes it possible to avoid reading errors, and therefore non-restitution of instructions for normally returnable products, caused by soiling, soiling, deterioration partial, etc. identification marking or reading device. The signals corresponding to the reading the marking are then processed by a function logical, for example "or" inclusive. In the case of processing by an inclusive “or” logic function, the recognition of marking by a single reading site therefore involves the return of the deposit. The second site, and possibly the following ones, therefore constitute sort of the compliance verification sites the marking.

Outre l'existence de deux sites de lecture du marquage du contenant, le positionnement du contenant par rapport à ces sites assure une fiabilité de lecture améliorée.Besides the existence of two sites for reading the marking container, positioning the container relative to these sites provide improved reading reliability.

En effet, le contenant à identifier, qui peut porter des souillures, salissures, etc., est suffisamment éloigné des éléments assurant la lecture pour éviter toute contamination ou détérioration de ceux-ci.Indeed, the container to be identified, which can carry soiling, soiling, etc. is sufficiently far away elements ensuring reading to avoid any contamination or deterioration of these.

Enfin, la distance suffisamment grande laissée entre ces éléments et le contenant permet d'assurer leur réglage en adaptant leur positionnement au contenant à identifier.Finally, the sufficiently large distance left between these elements and the container ensures their adjustment by adapting their positioning to the container to be identified.

Le perfectionnement du dispositif de lecture de marquage selon l'invention est également constitué par l'utilisation d'au moins deux cellules émettrices de faisceaux lumineux et deux capteurs photoélectriques, disposés par paire, par site de reconnaissance.The improvement of the reading device marking according to the invention also consists of the use of at least two cells emitting light beams and two photoelectric sensors, arranged in pairs, by reconnaissance site.

Le nombre de ces paires cellule/capteur varie selon la complexité du marquage à identifier. Un marquage complexe, et par conséquent difficilement falsifiable pourra être reconnu par la combinaison de multiples paires cellule/capteur.The number of these cell / sensor pairs varies according to the complexity of the marking to be identified. Complex marking, and therefore difficult to falsify could be recognized by the combination of multiple pairs cell / sensor.

Lorsqu'un contenant est placé en position d'identification, ces cellules émettent des faisceaux lumineux tels que la lumière blanche, des rayons laser, ultraviolets, infrarouges, etc. dont la réflexion varie en fonction de la zone rencontrée dudit contenant. En effet, une zone marquée ne réfléchit pas ces faisceaux comme une zone non marquée. Les faisceaux réfléchis sont alors reçus par les capteurs photoélectriques qui analysent numériquement ces signaux, réalisent une combinaison qui est ensuite comparée à une combinaison de référence mémorisée à l'aide d'une carte pouvant contenir un microprocesseur par un procédé connu.When a container is placed in position of identification, these cells emit beams bright such as white light, laser beams, ultraviolet, infrared, etc. whose reflection varies in depending on the area encountered of said container. Indeed, a marked area does not reflect these beams as a unmarked area. The reflected beams are then received by photoelectric sensors that analyze digitally these signals, achieve a combination which is then compared to a reference combination stored at using a card that can contain a microprocessor by a known process.

L'instruction de restitution de consigne est alors donnée si le marquage a été reconnu.The instruction to return the deposit is then given if the marking has been recognized.

EXEMPLES DE REALISATION DE L'INVENTIONEXAMPLES OF EMBODIMENT OF THE INVENTION

La figure 1 représente une partie à encastrer (4) du dispositif général de l'appareil de déconsignation selon l'invention. Elle montre particulièrement l'introduction du contenant (1) dans la goulotte (9) représentée sur la figure 3. Des lampes d'introduction (2) et de récupération (3) indiquent l'évolution du procédé d'identification du contenant (1) précédant la délivrance ou non dans le réceptacle à pièces (7) des pièces correspondant à la valeur de la consigne.Figure 1 shows a built-in part (4) of the general device of the disconnection device according to the invention. It particularly shows the introduction of the container (1) in the chute (9) shown in the figure 3. Introductory (2) and recovery (3) lamps indicate the evolution of the identification process of the containing (1) preceding the issue or not in the coin receptacle (7) for coins corresponding to the value of the deposit.

La figure 2 permet de suivre le cheminement du contenant et des pièces dans l'appareil de déconsignation selon l'invention. Le contenant (1) est introduit dans la goulotte d'introduction, glisse entre deux mâchoires, situées dans le sas de lecture, qui l'immobilisent de façon précise par rapport à une pluralité de paires cellule/capteur disposées en deux sites (seul le site (10A) est représenté) afin d'assurer une identification fiable du marquage.Figure 2 shows the progress of the container and parts in the voucher according to the invention. The container (1) is introduced into the introduction chute, slides between two jaws, located in the reading airlock, which immobilize it so precise with respect to a plurality of pairs cell / sensor arranged in two sites (only the site (10A) is shown) to ensure reliable identification of the marking.

La combinaison des paires cellule/capteur (11a), (11b) et (11c) permet d'identifier la présence d'un type de contenant autre que celui prévu pour l'appareil en détectant le cheminement temporel du contenant.The combination of cell / sensor pairs (11a), (11b) and (11c) identifies the presence of a type of container other than that intended for the device by detecting the time path of the container.

Les paires cellule/capteur (11b) et (11c) servent à contrôler le cheminement, représenté par la flèche (8), dans le bon sens du contenant. Quand le signal de fin de passage du contenant (1) est reçu par le capteur correspondant, généralement le plus proche du réceptacle de contenants usagés, la consigne est restituée. Les pièces stockées dans le rotor de stockage (5) sont libérées dans le conduit de descente des pièces (6) et chutent dans le réceptacle (7).The cell / sensor pairs (11b) and (11c) are used to check the path, represented by the arrow (8), in the common sense of the container. When the end of passage signal container (1) is received by the corresponding sensor, usually the closest to the container receptacle used, the deposit is returned. The parts stored in the storage rotor (5) are released in the lowering of the parts (6) and fall into the receptacle (7).

Dans la figure 3, le contenant (1), après son introduction par la goulotte (9), est immobilisé entre deux mâchoires (15) dans le sas de lecture (12) dans sa position de lecture. In Figure 3, the container (1), after its introduction by the chute (9), is immobilized between two jaws (15) in the reading airlock (12) in its position of reading.

Les figures 4, 5 et 6 représentent particulièrement un exemple de positionnement du dispositif de reconnaissance (10) du marquage du contenant (1), du dispositif de reconnaissance de conformité du type de contenant constitué par les paires (11a), (11b) et (11c) et du dispositif de contrôle du bon cheminement du contenant (11b) et (11c).Figures 4, 5 and 6 particularly represent a example of positioning of the recognition device (10) marking of the container (1), of the recognition of conformity of the type of container formed by the pairs (11a), (11b) and (11c) and of the control of the correct progress of the container (11b) and (11c).

Les paires cellule/capteur (10) du dispositif d'identification de marquage sont disposées en deux sites (10A) et (10B). Des fenêtres ouvertes dans la paroi du sas de lecture (12) leur permettent d'émettre vers le contenant (1) et de recevoir de celui-ci des faisceaux lumineux. Chaque paire cellule/capteur de chaque site de lecture (10A) ou (10B) est disposée de façon à ce que la cellule émettrice soit placée sur le même site que le capteur qui lui est associé, pouvant ainsi capter le faisceau réfléchi.The cell / sensor pairs (10) of the device identification marking are arranged in two sites (10A) and (10B). Open windows in the airlock wall read (12) allow them to send to the container (1) and to receive light beams from it. Each cell / sensor pair of each reading site (10A) or (10B) is arranged so that the transmitting cell is placed on the same site as the sensor assigned to it associated, thus being able to capture the reflected beam.

Pour les paires cellule/capteur (11a) (11b) (11c) des autres dispositifs, les cellules émettrices sont diamétralement opposées aux capteurs qui leur sont associés.For cell / sensor pairs (11a) (11b) (11c) of other devices, the emitting cells are diametrically opposed to the sensors associated with them.

La figure 6 représente, de plus, le dispositif permettant l'immobilisation du contenant (1) par des mâchoires (15). Un ressort (14) les maintient au repos pour retenir le contenant (1) et permet de les écarter par actionnement d'une came (13) entraínée par un moteur selon un procédé connu pour libérer ledit contenant.Figure 6 shows, in addition, the device allowing the immobilization of the container (1) by jaws (15). A spring (14) keeps them at rest for retain the container (1) and allows them to be separated by actuation of a cam (13) driven by a motor according to a known method for releasing said container.

L'invention sera mieux comprise par la lecture d'un exemple de réalisation préférée appliquée à un appareil pour la déconsignation d'un contenant (1), notamment de gobelets délivrés par les distributeurs automatiques de boissons chaudes ou froides, par l'identification d'un marquage déterminé réalisé sur ce contenant. Le dessin déterminé permettant l'identification fiable du gobelet est effectué par marquage graphique ou sérigraphique du contenant avec une encre alimentaire conductrice ou non selon un procédé connu.The invention will be better understood by reading a preferred embodiment example applied to a device for the withdrawal of a container (1), in particular from cups issued by vending machines for drinks hot or cold, by identifying a marking determined made on this container. The determined design allowing reliable identification of the cup is performed by graphic or serigraphic marking of the container with a conductive or non-conductive food ink according to a process known.

Le gobelet (1) introduit dans l'appareil est d'abord placé dans une position préétablie devant le dispositif de lecture du marquage. Pour ce faire, il est introduit dans l'appareil par la goulotte (9) dans le sens vertical, son ouverture vers le haut. En descendant dans l'appareil il passe entre deux mâchoires (15) qui constituent un moyen connu d'immobilisation de tels récipients.The cup (1) introduced into the device is first placed in a predetermined position in front of the reading of the marking. To do this, it is introduced in the device by the chute (9) in the vertical direction, its opening up. Going down into the device there passes between two jaws (15) which constitute a means known immobilization of such containers.

Le gobelet est ainsi toujours immobilisé au même endroit dans la même position dans le sas de lecture (12).The cup is thus always immobilized at the same place in the same position in the reading airlock (12).

Une fois immobilisé, il est soumis à l'identification de son marquage. Celle-ci est effectuée à l'aide d'un dispositif de lecture comportant au moins deux sites (10A) et (10B) de lecture constitués chacun par une pluralité de paires cellule/capteur (10) telles que décrites précédemment. Ces paires sont disposées de manière fixe à des points précis autour du gobelet et a une distance de celui-ci comprise entre 3 et 7 mm. Ces sites permettant la redondance de lecture sont mobiles ou fixes et généralement disposés de façon à effleurer la paroi du sas.Once immobilized, it is subject to identification of its marking. This is done using a reading device comprising at least two sites (10A) and (10B) for reading each consisting of a plurality of cell / sensor pairs (10) as described previously. These pairs are fixedly arranged at specific points around the cup and at a distance of this between 3 and 7 mm. These sites allowing the read redundancy are mobile or fixed and usually arranged so as to touch the wall of the airlock.

Le marquage du gobelet (1) constituant une série de codes clairs et de codes foncés et chaque cellule émettant un faisceau lumineux dirigé sur une zone déterminée du gobelet, la réflexion de ce faisceau est différente selon qu'il rencontre une zone foncée ou une zone claire (zone marquée ou zone non marquée) du gobelet. La lecture de cette réflexion se fait à distance par le capteur photoélectrique associé à chaque cellule. Par exemple, une zone claire renvoie un niveau logique zéro, une zone foncée renvoi un niveau logique 1.The marking of the cup (1) constituting a series of clear codes and dark codes and each emitting cell a light beam directed on a determined area of the cup, the reflection of this beam is different depending whether it meets a dark area or a light area (area marked or unmarked area) of the cup. Reading this reflection is done remotely by the photoelectric sensor associated with each cell. For example, a light area returns a logic level zero, a dark area returns a logic level 1.

Les informations ainsi reçues et interprétées numériquement par les capteurs, fournissent une combinaison. A l'aide d'une carte électronique pouvant contenir un microprocesseur, cette combinaison est ensuite comparée à une combinaison de référence préalablement mémorisée pour un marquage déterminé selon un procédé connu.The information thus received and interpreted digitally by sensors, provide a combination. Using an electronic card that can contain a microprocessor, this combination is then compared to a reference combination previously stored for a marking determined according to a known process.

Si les combinaisons sont identiques, la restitution de la consigne est accordée. Dans le cas contraire, la consigne n'est pas restituée.If the combinations are identical, the restitution of the deposit is granted. Otherwise, the instruction is not returned.

Une variante de cette réalisation préférée possède un dispositif de contrôle de la conformité du type de contenant introduit dans l'appareil. Ce dispositif est constitué par les trois paires cellules/capteurs (11a), (11b) et (11c) capables de détecter le cheminement temporel du contenant. Un contenant non conforme n'est pas immobilisé par les mâchoires (15) et tombe directement dans le réceptacle de contenants usagés. Sa non conformité est signalée par la rapidité de cette chute, la consigne n'est pas restituée. Au contraire, un contenant du type prévu par l'appareil de déconsignation est immobilisé par les mâchoires. Son marquage devra alors être identifié pour que la consigne soit restituée.A variant of this preferred embodiment has a container type control system introduced into the device. This system consists of the three cell / sensor pairs (11a), (11b) and (11c) capable of detecting the time path of the container. A non-conforming container is not immobilized by jaws (15) and falls directly into the receptacle of used containers. Its non-compliance is signaled by the rapidity of this fall, the deposit is not returned. At on the contrary, a container of the type provided by the disallowed is immobilized by the jaws. His marking must then be identified so that the deposit is returned.

Une réalisation préférée d'un appareil de déconsignation, selon l'invention, possède un dispositif de lecture de marquage du contenant constitué de deux sites de lecture (10A) et (10B) diamétralement opposés dans le sas de lecture (12), comportant chacun trois paires cellule/capteur (10) celles-ci étant situées à une distance comprise entre 3 et 7 mm du contenant mis en place pour identification.A preferred embodiment of a according to the invention, has a device for reading of marking of the container made up of two sites of diametrically opposed reading (10A) and (10B) in the airlock reading (12), each comprising three cell / sensor pairs (10) these being located at a distance of between 3 and 7 mm from the container put in place for identification.

Une variante de réalisation de l'invention possède des cellules émettrices de rayons infrarouges et leurs capteurs photoélectriques associés.An alternative embodiment of the invention has infrared emitting cells and their sensors associated photoelectric.

Une autre variante de réalisation de l'invention possède, en outre, un dispositif de sécurité ne permettant la délivrance de la consigne du contenant (1) consigné et identifié qu'après sa chute dans un réceptacle de récupération.Another variant embodiment of the invention also has a safety device which does not allow issuing the deposit for the returnable container (1) and identified that after falling into a receptacle of recovery.

En effet, ce dispositif de sécurité empêche la restitution d'une consigne si le contenant chemine dans le sens opposé à celui le menant à ce réceptacle.Indeed, this safety device prevents the return of a deposit if the container travels in the opposite direction to that leading to this receptacle.

Ce système est constitué par au moins deux paires cellule émettrice de faisceau lumineux/capteur photoélectrique (11b) et (11c), la première pouvant également, selon son positionnement par rapport au contenant immobilisé, servir de dispositif de détection de présence d'un contenant.This system consists of at least two pairs light beam emitting cell / sensor photoelectric (11b) and (11c), the former being able also, depending on its positioning in relation to the container immobilized, serve as presence detection device of a container.

Ces paires sont disposées à différents niveaux du chemin suivi par le contenant. Cette disposition permet de contrôler le sens du passage du gobelet.These pairs are arranged at different levels of the path followed by the container. This arrangement allows check the direction of passage of the cup.

Chaque cellule est diamétralement opposée au capteur qui lui est associé et affleure la paroi du conduit guidant le contenant vers le réceptacle de récupération. La cellule émet constamment un faisceau lumineux reçu par le capteur. Le signal du passage du gobelet est donné par l'interruption de la réception de ce faisceau par ce capteur.Each cell is diametrically opposite the sensor associated with it and is flush with the wall of the guide duct the container to the recovery receptacle. The cell constantly emits a light beam received by the sensor. The signal for the passage of the cup is given by the interruption of the reception of this beam by this sensor.

La restitution de la consigne n'est accordée qu'après la fin de l'interruption de la réception du faisceau lumineux par le capteur (11c) le plus proche du réceptacle de récupération.The return of the deposit is only granted after the end of the beam reception interruption illuminated by the sensor (11c) closest to the receptacle recovery.

L'efficacité du dispositif de sécurité est augmentée par sa capacité à détecter le cheminement du contenant du réceptacle de récupération vers la goulotte d'introduction (9).The efficiency of the safety device is increased by its ability to detect the path of the container recovery receptacle to the introduction chute (9).

En effet, un tel cheminement provoque une suite d'obstructions et de destructions des paires (11c), (11b) et (11a) de la paire (11c) à la paire (11a) engendrant une commande d'inhibition de la restitution de consignes.Indeed, such a progression causes a continuation obstructions and destructions of the pairs (11c), (11b) and (11a) from the pair (11c) to the pair (11a) generating a command to inhibit the return of instructions.
