De manière caractéristique à l'invention, le poste 5 de dosage comprend au moins un capteur 13 de détection de présence d’un récipient 33 collecteur à l’intérieur de ladite enceinte 6. Ce récipient 33 collecteur est introduit dans l'enceinte 6 par une ouverture 9 de l'enceinte 6 disposée généralement en façade de l'enceinte 6. L’unité 14 de pilotage est configurée pour commander la machine 1 au moins en fonction des données fournies par le capteur 13 de détection de présence d’un récipient 33 collecteur à l’intérieur de ladite enceinte 6. En particulier, l'unité 14 de pilotage est configurée pour empêcher le fonctionnement du système 10 de vidange à l'état détecté d'une absence du récipient 33 collecteur à l'intérieur de ladite enceinte par le capteur 13 de détection de présence dudit récipient 33 collecteur. Ce capteur 13 de détection de présence empêche la commande d'une vidange du conteneur associé à un emplacement 4 de réception disposé en regard de l'ouverture 8 d'accès de l'enceinte 6 en l'absence d'un récipient 33 collecteur sur le support 7 de réception du récipient 33 collecteur. Characteristically of the invention, the metering station 5 comprises at least one sensor 13 for detecting the presence of a collecting container 33 inside said chamber 6. This collecting container 33 is introduced into the chamber 6 by an opening 9 of the enclosure 6 generally disposed on the front of the enclosure 6. The control unit 14 is configured to control the machine 1 at least as a function of the data supplied by the sensor 13 for detecting the presence of a container 33 collector inside said enclosure 6. In particular, the control unit 14 is configured to prevent the operation of the emptying system 10 in the detected state of an absence of the collector container 33 inside said. enclosure by the sensor 13 for detecting the presence of said collecting container 33. This presence detection sensor 13 prevents the control of an emptying of the container associated with a reception location 4 arranged opposite the access opening 8 of the enclosure 6 in the absence of a collecting container 33 on the support 7 for receiving the collecting container 33.
Dans l'exemple représenté, ce support 7 de réception du récipient 33 collecteur est formé par un plateau disposé à l'intérieur de l'enceinte 6. Ce support 7 de réception d'un récipient 33 collecteur est équipé d'un système 18 de pesée, tel qu'un peson ou un capteur de pesée. Le capteur 13 de détection peut être disposé au niveau de la moitié supérieure de l'enceinte 6 du poste 5 de dosage comme illustré à la figure 1A. Dans ce mode de réalisation, le capteur 13 de détection de présence d’un récipient 33 collecteur est un capteur comprenant deux parties 131 , 132 disposées en regard l’une de l’autre au niveau de la moitié supérieure de l’enceinte 6 du poste 5 de dosage. Ce capteur est ici un capteur optique mais aurait pu, de manière équivalente, être réalisé sous forme d'un capteur analogique. In the example shown, this support 7 for receiving the collecting container 33 is formed by a plate arranged inside the enclosure 6. This support 7 of reception of a collecting container 33 is equipped with a weighing system 18, such as a load cell or a load cell. The detection sensor 13 can be arranged at the level of the upper half of the enclosure 6 of the dosing station 5 as illustrated in FIG. 1A. In this embodiment, the sensor 13 for detecting the presence of a collecting container 33 is a sensor comprising two parts 131, 132 arranged facing each other at the level of the upper half of the enclosure 6 of the dosing station 5. This sensor is here an optical sensor but could, in an equivalent manner, have been produced in the form of an analog sensor.
En variante ou en complément, le capteur 13 peut être intégré au système 18 de pesée. Le support 7 de réception d'un récipient 33 collecteur peut également être monté mobile en monte et baisse à l'intérieur de l'enceinte 6 dans le sens d'un rapprochement ou d'un écartement de l'ouverture 8 d'accès à l'enceinte 6 ménagée dans la partie 61 supérieure de l'enceinte 6 du poste 5 de dosage à la verticale et au-dessus du support 7 de réception du récipient 33 collecteur. Le déplacement en monte et baisse du support 7 de réception d'un récipient 33 collecteur permet d'amener le dessus ouvert du récipient 33 collecteur au plus près du plafond de l'enceinte 6 du poste 5 de dosage pour éviter que des vapeurs de composés organiques volatils se répandent dans l'enceinte pendant le transfert de fluide depuis un emplacement 4 de réception d'un conteneur du bâti 3 support vers le récipient 33 collecteur de l'enceinte 6 du poste 5 de dosage. L'entraînement en déplacement en monte et baisse du support 7 de réception d'un récipient 33 collecteur peut s'opérer manuellement, par exemple par déplacement à coulissement du support 7 le long de rails dits verticaux disposés à l'intérieur de l'enceinte 6 et un dispositif 23 de maintien en position du support 7 peut être prévu. Ce dispositif 23 de maintien en position du support de réception d'un récipient 33 collecteur peut, comme dans l'exemple représenté à la figure 1 B, être formé par un bouton à ressort solidaire en déplacement du support 7, ce bouton à ressort venant se verrouiller dans l'un des crans d'une série de crans disposés sur une paroi de l'enceinte le long d'une ligne parallèle à la direction de déplacement en monte et baisse du support 7. En variante, le support 7 de réception d'un récipient 33 collecteur peut être monté mobile en monte et baisse à l'aide d'un actionneur, tel qu'un vérin. Dans ce cas, l'actionneur fait également office de dispositif de maintien du support 7 dans l'une quelconque des positions aptes à être prises par ledit support 7. As a variant or in addition, the sensor 13 can be integrated into the weighing system 18. The support 7 for receiving a collecting container 33 can also be mounted so as to move up and down inside the enclosure 6 in the direction of an approach or a separation of the opening 8 for access to the enclosure 6 formed in the upper part 61 of the enclosure 6 of the metering station 5 vertically and above the support 7 for receiving the collecting container 33. The upward and downward movement of the support 7 for receiving a collecting container 33 makes it possible to bring the open top of the collecting container 33 as close as possible to the ceiling of the enclosure 6 of the dosing station 5 to prevent vapors of compounds. volatile organic compounds spread in the enclosure during the transfer of fluid from a location 4 for receiving a container of the support frame 3 to the collecting container 33 of the enclosure 6 of the dosing station 5. The upward and downward movement drive of the support 7 for receiving a collecting receptacle 33 can be carried out manually, for example by sliding movement of the support 7 along so-called vertical rails placed inside the enclosure. 6 and a device 23 for holding the support 7 in position can be provided. This device 23 for holding the support for receiving a collecting receptacle 33 in position can, as in the example shown in FIG. 1B, be formed by a spring button integral with the movement of the support 7, this spring button coming from to be locked in one of the notches of a series of notches arranged on a wall of the enclosure along a line parallel to the direction of movement up and down of the support 7. As a variant, the receiving support 7 a collecting container 33 can be mounted mobile up and down using an actuator, such as a cylinder. In this case, the actuator also acts as a device for holding the support 7 in any one of the positions suitable for being taken by said support 7.
Pour parfaire l'ensemble, le poste 5 de dosage de la machine 1 de distribution de produit est équipé d'un circuit 15 de circulation de fluide gazeux de communication de l'enceinte 6 avec l'extérieur de ladite enceinte 6. Ce circuit 15 de circulation de fluide comprend un dispositif 16A de circulation forcée d’air ou est équipé d’un raccord 17 raccordable à un dispositif 16B de circulation forcée d’air comme illustré à la figure 1A. Dans le cas d'un dispositif 16A de circulation forcée d'air intégré à la machine 1 de distribution comme illustré à la figure 1 B, ce dispositif 16A de circulation forcée d'air peut être formé par un simple ventilateur disposé sur le circuit 15 de circulation de fluide gazeux de communication de l'enceinte 6 avec l'extérieur de l'enceinte 6. To complete the assembly, the metering station 5 of the product dispensing machine 1 is equipped with a circuit 15 for circulating gaseous fluid in communication from the enclosure 6 with the outside of said enclosure 6. This circuit 15 fluid circulation device comprises a forced air circulation device 16A or is equipped with a connector 17 connectable to a forced air circulation device 16B as illustrated in FIG. 1A. In the case of a forced air circulation device 16A integrated into the dispensing machine 1 as illustrated in FIG. 1B, this forced air circulation device 16A can be formed by a simple fan arranged on the circuit 15 circulation of gaseous communication fluid of the enclosure 6 with the exterior of the enclosure 6.
Dans le cas d'un dispositif 16B de circulation forcée d'air raccordable à la machine 1 de distribution de produits, ce dispositif 16B de circulation forcée d'air peut être formé par un réseau d'air comprimé ou un générateur d'air sous pression, tel qu'un compresseur. Indépendamment de la conception du dispositif 16Aou 16B de circulation forcée d'air, le circuit 15 de circulation de fluide gazeux de communication de l'enceinte 6 avec l'extérieur de l'enceinte 6, en particulier avec l'extérieur de la machine, est raccordée à l'enceinte 6 au niveau de l'ouverture 8 d'accès à l'enceinte disposée dans la partie supérieure de l'enceinte et débouche dans ladite ouverture. Ce circuit 15 de circulation de fluide gazeux comprend au moins un organe 19 d'obturation du circuit 15 et l'unité 14 de pilotage de la machine 1 est configurée pour commander le déplacement de l'organe 19 d'obturation entre une position fermée et une position ouverte, de préférence, au moins en fonction des données fournies par le capteur 13 de détection de présence d'un récipient 33 collecteur à l'intérieur de ladite enceinte 6. Ainsi, l'unité 14 de pilotage peut être configurée pour, en l'absence de détection d'un récipient 33 collecteur à l'intérieur de l'enceinte 6, maintenir l'organe 19 d’obturation du circuit 15 de circulation de fluide gazeux de communication de l'enceinte 6 avec l'extérieur de l'enceinte 6 en position fermée. Dans le cas d'un dispositif 16A de circulation forcée d'air intégré à la machine 1 de distribution de produits et formé par au moins un ventilateur, l'unité 14 de pilotage peut être configurée pour commander le fonctionnement du ventilateur uniquement à l'état détecté d'un récipient 33 collecteur sur le support 7 de réception d'un tel récipient. In the case of a forced air circulation device 16B which can be connected to the product dispensing machine 1, this forced air circulation device 16B can be formed by a compressed air network or an air generator under pressure, such as a compressor. Regardless of the design of the device 16A or 16B for forced air circulation, the circuit 15 for circulating gaseous fluid in communication from the enclosure 6 with the outside of the enclosure 6, in particular with the outside of the machine, is connected to the enclosure 6 at the level of the opening 8 for access to the enclosure arranged in the upper part of the enclosure and opens into said opening. This circuit 15 for circulating gaseous fluid comprises at least one member 19 for shutting off the circuit 15 and the unit 14 for controlling the machine 1 is configured to control the movement of the member 19 for shutting off between a closed position and an open position, preferably, at least as a function of the data supplied by the sensor 13 for detecting the presence of a collecting container 33 inside said enclosure 6. Thus, the control unit 14 can be configured for, in the absence of detection of a collecting container 33 inside the enclosure 6, maintain the member 19 for closing off the circuit 15 for the circulation of gaseous fluid for communication of the enclosure 6 with the outside of enclosure 6 in the closed position. In the case of a device 16A for forced air circulation integrated into the product dispensing machine 1 and formed by at least one fan, the control unit 14 can be configured to control the operation of the fan only at the detected state of a collecting container 33 on the support 7 for receiving such a container.
Dans l'exemple représenté à la figure 1A, le circuit 15 de circulation de fluide gazeux de communication de l’enceinte 6 avec l’extérieur de l’enceinte 6 dans le sens d'une circulation du fluide gazeux vers l'extérieur de l'enceinte 6, en particulier vers l'extérieur de la machine comprend une branche 151 de raccordement du circuit 15 à un dispositif 16B de circulation forcée d’air. L’organe 19 d’obturation du circuit 15 est disposé sur ladite branche 151 . Cette branche 151 obturable du circuit 15 est équipée, dans sa zone 21 de raccordement à une branche 152 dite principale du circuit 15, d’un système venturi 22. In the example shown in FIG. 1A, the circuit 15 for the circulation of gaseous fluid communicating the enclosure 6 with the outside of the enclosure 6 in the direction of a circulation of the gaseous fluid towards the outside of the The enclosure 6, in particular towards the outside of the machine, comprises a branch 151 for connecting the circuit 15 to a device 16B for forced air circulation. The shutter member 19 of the circuit 15 is disposed on said branch 151. This closable branch 151 of circuit 15 is equipped, in its zone 21 for connection to a so-called main branch 152 of circuit 15, with a venturi system 22.
Pour parfaire l'ensemble, l'enceinte 6 du poste 5 de dosage peut comprendre un capteur 20 de détection de composés organiques volatils. Dans ce cas, l'unité 14 de pilotage de la machine est configurée pour commander l'organe 19 d'obturation du circuit 15 de circulation de fluide gazeux de communication de l'enceinte 6 avec l'extérieur de ladite enceinte 6 en fonction des données fournies par le capteur 20 de détection de composés organiques volatils à l'intérieur de ladite enceinte. To complete the whole, the enclosure 6 of the metering station 5 may include a sensor 20 for detecting volatile organic compounds. In this case, the machine control unit 14 is configured to control the member 19 for shutting off the circuit 15 for the circulation of gaseous fluid in communication of the enclosure 6 with the outside of said enclosure 6 as a function of data supplied by the sensor 20 for detecting volatile organic compounds inside said enclosure.
Le procédé de commande en fonctionnement d'une machine 1 de distribution, telle que décrite ci-dessus, peut donc comprendre au moins une étape de détection de présence d'un récipient 33 collecteur à l'intérieur de ladite enceinte 6 et une étape de circulation forcée de fluide gazeux dans le circuit 15 de circulation de fluide gazeux de communication de l'enceinte 6 avec l'extérieur de ladite enceinte 6. Ce procédé comprend encore au moins une étape d'entraînement en déplacement en élévation du support 7 de réception d'un récipient 33 collecteur dans le sens d'un rapprochement de l'ouverture 8 d'accès ménagée dans la partie 61 supérieure de l'enceinte 6 du poste 5 de dosage. Ce déplacement permet l'amenée en appui du dessus du récipient 33 collecteur sur le plafond de l'enceinte 6 de sorte que les vapeurs de solvant sont confinées dans le récipient 33 collecteur. The method for controlling in operation a dispensing machine 1, as described above, can therefore comprise at least one step of detecting the presence of a collecting container 33 inside said chamber 6 and a step of forced circulation of gaseous fluid in the circuit 15 for the circulation of gaseous fluid in communication of the enclosure 6 with the exterior of said enclosure 6. This method also comprises at least one step of driving in elevation movement of the receiving support 7 a collecting container 33 in the direction of approaching the access opening 8 provided in the upper part 61 of the enclosure 6 of the metering station 5. This movement allows the supply to rest the top of the collecting container 33 on the ceiling of the enclosure 6 so that the solvent vapors are confined in the collecting container 33.
Ce procédé comprend encore au moins une étape d'entraînement en déplacement en élévation de l'enceinte 6 du poste de dosage dans le sens d'un rapprochement de la zone 2 de stockage. This method also comprises at least one step of driving in elevation displacement of the enclosure 6 of the metering station in the direction of approaching the storage zone 2.
Ce procédé comprend également, pour la mise en œuvre de l'étape de circulation forcée de fluide gazeux dans le circuit 15 de circulation de fluide gazeux, au moins une étape d'ouverture de l'organe d'obturation équipant ledit circuit et si nécessaire, une étape de mise en marche du dispositif 16A ou 16B de circulation forcée d'air. This method also comprises, for the implementation of the step of forced circulation of gaseous fluid in the gaseous fluid circulation circuit 15, at least one step of opening the closure member equipping said circuit and if necessary , a step of starting the device 16A or 16B for forced air circulation.
Dans le détail, le fonctionnement d'une machine de distribution, telle que décrite ci-dessus, peut être tel que suit. On suppose qu'un conteneur a été présélectionné de manière automatique par un opérateur via par exemple une interface homme/machine équipant ladite machine 1 . L'emplacement 4 de réception du conteneur 30 associé est positionné au-dessus et en regard de l'ouverture 8 d'accès ménagée dans la partie supérieure 61 de l’enceinte 6 du poste 5 de dosage en vue de la vidange partielle ou totale du conteneur. Un récipient 33 collecteur est introduit à l'intérieur de l'enceinte 6 via une ouverture d'entrée dans l'enceinte 6 et est disposé à l'intérieur de l'enceinte 6 sur le support 7 de réception d'un récipient 33 collecteur. Le support 7 est, si nécessaire, élevé pour amener le haut du récipient 33 collecteur au plus proche du plafond de l'enceinte 6 de sorte que le bord de l'ouverture du récipient 33 collecteur entoure l'ouverture 8 d'accès ménagée dans la partie 61 supérieure de l'enceinte 6 du poste 5 de dosage. Ce récipient 33 collecteur est détecté par le capteur 13 de détection de présence. L'enceinte 6 du poste de dosage est élevée pour permettre au dispositif 1 1 de commande en ouverture/fermeture d'un conteneur 30 de venir entourer la valve 31 de vidange du conteneur, cette valve 31 se logeant partiellement dans l'ouverture 8 d'accès de l'enceinte 6. Une compression est appliquée via le dispositif 12 d'alimentation en air sous pression sur la poche souple constitutive du conteneur 33 pour en permettre sa vidange à l'état ouvert de la valve de vidange du conteneur commandée en ouverture par le dispositif 1 1 de commande en ouverture/fermeture. La valve est ouverte pendant une durée contrôlée à partir des données issues du pesage opéré en continu par le système 18 de pesée jusqu'à obtenir la masse exacte requise. La valve peut alors être fermée. La pression est maintenue sur la poche souple du conteneur 30 au moins pendant toute la phase de vidange. Une fois la vidange achevée et la valve 31 de vidange fermée, l'enceinte 6 peut être rabaissée. Une nouvelle vidange peut être opérée après sélection d'un nouveau conteneur par répétition des opérations décrites ci-dessus. Au cours d'une vidange, le dispositif 16A ou 16B de circulation forcée d'air peut être activé et l'organe 19 d'obturation du circuit 15 de circulation de fluide gazeux de communication de l'enceinte 6 avec l'extérieur de l'enceinte 6, lorsqu'il est présent, peut être ouvert pour permettre une évacuation d'au moins une partie du contenu de l'enceinte 6, c'est- à-dire du volume de l'enceinte 6 contenant des composés organiques volatils, à l'extérieur de l'enceinte 6 pour éviter tout risque d'explosion. Le pilotage de l'organe 19 d'obturation du circuit 15 de circulation de fluide gazeux de communication de l'enceinte 6 avec l'extérieur de l'enceinte 6 et/ou du dispositif 16A ou 16B de circulation forcée d'air peuvent être parfaits à l'aide du capteur 20 de détection de composés organiques volatils lorsqu'un tel capteur est prévu ou à l'aide du système 18 de pesée. In detail, the operation of a dispensing machine, as described above, may be as follows. It is assumed that a container has been automatically preselected by an operator via for example a man / machine interface equipping said machine 1. The location 4 for receiving the associated container 30 is positioned above and facing the access opening 8 made in the upper part 61 of the enclosure 6 of the metering station 5 with a view to partial or total emptying. of the container. A collecting receptacle 33 is introduced inside the enclosure 6 via an inlet opening in the enclosure 6 and is placed inside the enclosure 6 on the support 7 for receiving a collector receptacle 33. . The support 7 is, if necessary, raised to bring the top of the collecting container 33 closer to the ceiling of the enclosure 6 so that the edge of the opening of the collecting container 33 surrounds the access opening 8 made in the upper part 61 of the enclosure 6 of the metering station 5. This collecting container 33 is detected by the presence detection sensor 13. The enclosure 6 of the dosing station is raised to allow the device 11 for controlling the opening / closing of a container 30 to surround the valve 31 for emptying the container, this valve 31 being partially housed in the opening 8 d access to the enclosure 6. Compression is applied via the pressurized air supply device 12. on the flexible bag constituting the container 33 to allow its emptying in the open state of the emptying valve of the container controlled in opening by the device 1 1 for controlling the opening / closing. The valve is open for a period of time controlled from the data resulting from the weighing operated continuously by the weighing system 18 until the exact mass required is obtained. The valve can then be closed. The pressure is maintained on the flexible pouch of the container 30 at least throughout the emptying phase. Once the emptying is complete and the drain valve 31 is closed, the enclosure 6 can be lowered. A new emptying can be carried out after selecting a new container by repeating the operations described above. During an emptying, the device 16A or 16B for forced air circulation can be activated and the member 19 for shutting off the circuit 15 for the circulation of gaseous fluid in communication of the enclosure 6 with the outside of the chamber. enclosure 6, when present, can be opened to allow evacuation of at least part of the contents of enclosure 6, that is to say of the volume of enclosure 6 containing volatile organic compounds , outside enclosure 6 to avoid any risk of explosion. The control of the member 19 for shutting off the circuit 15 for circulating gaseous fluid of the enclosure 6 with the outside of the enclosure 6 and / or of the device 16A or 16B for forced air circulation can be perfect using the sensor 20 for detecting volatile organic compounds when such a sensor is provided or using the weighing system 18.
L'organe 19 d'obturation du circuit 15 de circulation de fluide gazeux de communication de l'enceinte 6 avec l'extérieur de l'enceinte 6 peut ainsi être fermé avant la fin de la pesée, lorsqu'il reste encore quelques grammes à peser, pour éviter des flux d'air qui pourraient perturber ou nuire à la précision du dosage. The member 19 for shutting off the circuit 15 for the circulation of gaseous fluid in communication between the enclosure 6 and the exterior of the enclosure 6 can thus be closed before the end of the weighing, when there are still a few grams left. weigh, to avoid air flows which could disturb or impair the accuracy of the dosage.
