Description

"Dispositif de convoyage pneumatique de cartouches" "Pneumatic cartridge conveying device"
La présente invention concerne un dispositif de convoyage pneumatique de cartouches. Ce convoyage a lieu entre au moins un poste de travail, un centre de stockage et une station de reddition par le biais d'un circuit de convoyage en relation avec un circuit d'aspiration ou de soufflerie. L'invention s'adresse a tout type de convoyage pneumatique notamment pour le transport de fonds ou pour tout autre communication par le biais de cartouches entraînées par unThe present invention relates to a pneumatic conveying device for cartridges. This conveying takes place between at least one work station, a storage center and a surrender station by means of a conveying circuit in relation to a suction or blower circuit. The invention is intended for any type of pneumatic conveying, in particular for the transport of funds or for any other communication by means of cartridges driven by a
Particulièrement, des transferts entre une station de péage, des zones de stockage intermédiaires et une station de reddition, entrent dans le cadre de l'invention.In particular, transfers between a toll station, intermediate storage areas and a surrender station, fall within the scope of the invention.
Dans ce domaine , on connaî t du documen t FR-A-2. 638. 12& une instal la tion de transport pneuma tique et protège d ' obj ets de valeur comportan t une première voie de transport unidirectionnelle de la zone a risques vers un poste de stockage intermédiaire et une seconde voie de transport unidirectionnelle du poste de stockage intermédiaire vers un poste de reddition ainsi qu'une voie de transport bidirectionnelle entre la zone a risques et un local αe surveillance et de commande .In this area, we know of the document FR-A-2. 638. 12 & a pneumatic transport instal tion and protects valuable objects including a first transport route unidirectional from the risk zone to an intermediate storage station and a second unidirectional transport path from the intermediate storage station to a surrender station as well as a bidirectional transport path between the risk zone and a monitoring and control room .
Bien qu'efficace, l'installation proposée par ce document nécessite l'usage de deux turbines distinctes, d'une part pour le convoyage individuel des cartouches et d'autre part pour la reddition des cartouches en fin de travail de l'employé.Although efficient, the installation proposed by this document requires the use of two separate turbines, on the one hand for the individual conveying of the cartridges and on the other hand for the surrender of the cartridges at the end of the employee's work.
En effet, pour la reddition des cartouches, la puissance nécessaire au convoyage est plus importante compte tenu du plus grand nombre de cartouches véhiculées.Indeed, for the surrender of cartridges, the power required for conveying is greater given the greater number of cartridges carried.
Les deux turbines mises en œuvre auront donc des puissances différentes.The two turbines used will therefore have different powers.
L'emploi de deux turbines ou plus pesé fortement sur le coût et la complexité de l'installation.The use of two or more turbines weighed heavily on the cost and complexity of the installation.
Par ailleurs, le circuit de reddition propose dans le cadre de cette technique est complexe et nécessite un circuit supplémentaire ainsi qu'un aiguillage particulier.Furthermore, the surrender circuit offered in the context of this technique is complex and requires an additional circuit as well as a specific switch.
On connaît, par ailleurs , du document WO--A82.00131 une installation de poste pneumatique avec un alimentation en air de propulsion réglable. Selon ce document, pour chaque boîte a transporter, on détecte, a l'aide d'un dispositif de mesure, des oonnees spécifiques de transport c' est-a-dire d'une part la vitesse d ' accélération et d'autre part des paramètres physiques qui, pour une pression donnée de l'air de propulsion, influencent la vitesse et l'accélération des boîtes A partir des valeurs d ' accélération ainsi obtenues , il est possible de régler 1 ' alimentation en air de propulsion de manière que les boîtes lourdes ou légères avec des bagues de glissement neuves ou usées atteignent une vitesse désirée . Il est ainsi possible d' obtenir a un poste de réception une arrivée reσuliere et douce des boîtes. Ce document propose une régulation de l'alimentation en air pour obtenir une vitesse constante de la ooîte a transporter quelque soit sa masse.Also known from document WO-A82.00131 is a pneumatic station installation with an adjustable propulsion air supply. According to this document, for each box to be transported, a specific means of transport is detected using a measuring device, that is to say on the one hand the speed of acceleration and on the other hand physical parameters which, for a given pressure of the propelling air, influence the speed and the acceleration of the gearboxes From the acceleration values thus obtained, it is possible to adjust the propelling air supply so that heavy or light boxes with new or worn slip rings reach a desired speed. It is thus possible to obtain at a reception station a regular and gentle arrival of the boxes. This document proposes a regulation of the air supply to obtain a constant speed of the box to transport whatever its mass.
Cette installation ne résout pourtant pas le problème de l'emploi de plusieurs turbines et d'installations complexes pour la circulation des cartouches dans le cadre de convoyages pneumatiques .This installation does not however solve the problem of the use of several turbines and complex installations for the circulation of the cartridges within the framework of pneumatic conveyances.
Il ne s'agit par ailleurs pas de réguler la puissance de l'alimentation en air selon le nombre de cartouches a véhiculer mais seulement suivant le poids d'une ooîte a transporter .It is also not a question of regulating the power of the air supply according to the number of cartridges to be transported but only according to the weight of a box to be transported.
La présente invention permet de pallier les inconvénients des installations actuelles et présente pour ce faire de nombreux avantages. En premier lieu, elle présente des moyens de variations de flux, des moyens d'aspiration et de soufflerie. De cette façon, on assouplit le fonctionnement des turbines utilisées dans les dispositifs.The present invention overcomes the drawbacks of current installations and has many advantages for doing this. Firstly, it presents means for flow variations, suction and blower means. In this way, the operation of the turbines used in the devices is made more flexible.
En effet, il sera possible, a partir d'une seule turbine de réaliser le convoyage de cartouches individuelles ou de cartouches en série.Indeed, it will be possible, from a single turbine to carry out the conveying of individual cartridges or cartridges in series.
L'usage d'une seule turbine simplifie les circαits de convoyage des cartouches ainsi que la conception nécessaire pour automatiser le fonctionnement de l'ensemble. Un autre but de l'invention est d'unifier l'ensemble des fonctionnalités du dispositif de convoyage.The use of a single turbine simplifies the conveying circuits of the cartridges as well as the design necessary to automate the operation of the assembly. Another object of the invention is to unify all of the functionalities of the conveying device.
Une installation de convoyage pneumatique comporte un ou plusieurs postes de travail (par exemple des postes de caisse dans les stations de péage) , un centre de stockage (par exemple un emplacement ou sont stockées les cartouches pleines de billets et de pièces de monnaie suite a un envoi d'operateurs depuis un poste de péage) et une station de reddition (par exemple un emplacement ou l'operateur viendra en fin de service récupérer les cartouches qu'il aura envoyées au centre de stockage au cours de son travail) .A pneumatic conveying installation comprises one or more work stations (for example cash desks in toll stations), a storage center (for example a location where the cartridges full of banknotes and coins are stored following a a dispatch of operators from a toll booth) and a surrender station (for example a location where the operator will come at the end of service recover the cartridges that he will have sent to the storage center during his work).
On observe que le dispositif doit remplir plusieurs fonctions . Dans un premier temps, le convoyage depuis les postes de travail jusqu'au centre de stockage de cartouches individuelles doit être réalise. De plus, la fonction de reddition est nécessaire pour que les employés puissent récupérer les cartouches a la fin de leur période de travail. Par ailleurs, d'autres fonctions telles que l'échange de cartouches ou l'approvisionnement en cartouches vides doivent être remplies par le dispositif.It is observed that the device must fulfill several functions. Firstly, conveying from the workstations to the storage center for individual cartridges must be carried out. In addition, the surrender function is necessary so that employees can collect the cartridges at the end of their shift. In addition, other functions such as exchanging cartridges or supplying empty cartridges must be fulfilled by the device.
L'invention permet d'unifier les circuits nécessaires a toutes ces fonctionnalités et emploie pour ce faire une seule ligne principale pour toutes les opérations.The invention makes it possible to unify the circuits necessary for all these functionalities and employs for this purpose a single main line for all the operations.
On évite ici le recours a des circuits complexes et multiples ainsi qu'a des dispositifs de détection ou de freinage des cartouches se multipliant d'autant plus que le nombre de circuits possibles est augmenté. D'autres buts et avantages apparaîtront au cours de la description suivante, qui n'est cependant pas limitative de 1 ' invention .This avoids the need for complex and multiple circuits as well as for devices for detecting or braking cartridges which multiply the more the number of possible circuits is increased.

La figure 2 est une autre vue générale dans laquelle les fonctions de reddition, d'échange et d'approvisionnement en cartouches sont présentées.FIG. 2 is another general view in which the functions of surrender, exchange and supply of cartridges are presented.
La figure 3 est un mode de réalisation particulier des moyens de variation de flux selon l'invention.Figure 3 is a particular embodiment of the flow variation means according to the invention.
Les figures 4 et 5 illustrent le fonctionnement des moyens de variation de flux dans ce mode de réalisation.Figures 4 and 5 illustrate the operation of the flow variation means in this embodiment.
Les figures 6 a 8 présentent des moyens de l'invention pour la reddition des cartouches. La figure 9 montre un autre mode de réalisation particulier de l'invention pour l'approvisionnement en cartouches vide.Figures 6 to 8 show means of the invention for the surrender of cartridges. FIG. 9 shows another particular embodiment of the invention for the supply of empty cartridges.
La figure 10 montre une possibilité de réalisation du centre de stockage. Le dispositif de convoyage selon l'invention comprend un circuit de convoyage 14 sous forme d'un reseau de tuyaux, reliant des zones emettrices ou/et réceptrices de cartouches 26.Figure 10 shows a possible embodiment of the storage center. The conveying device according to the invention comprises a conveying circuit 14 in the form of a network of pipes, connecting emitting or receiving zones of cartridges 26.
Ce circuit 14 comprend notamment une ligne principale 5. Les cartouches pourront être d'un type couramment utilise dans le domaine du transfert de fonds pour stations de péage. Elles renferment généralement les billets et pièces de monnaie issus des péages. Les zones emettrices ou/et réceptrices pourront présenter diverses configurations et localisations.This circuit 14 notably includes a main line 5. The cartridges may be of a type commonly used in the field of money transfer for toll stations. They generally contain notes and coins from tolls. The transmitting and / and receiving zones may have various configurations and locations.
Une vue générale d'un tel ensemble est présentée en figure 1.A general view of such an assembly is presented in Figure 1.
On y voit trois postes de travail 1 au niveau desquels les operateurs peuvent recevoir et émettre des cartouches tout au long de leur travail.There are three workstations 1 at which operators can receive and issue cartridges throughout their work.
Est également illustre un centre de stockage 2. Il pourra s'agir d'un emplacement de stockage intermédiaire des cartouches 26, s 'amassant au fur et a mesure de la collecte au niveau des postes de travail 1 et restituées en fin de travail .A storage center 2 is also illustrated. It may be an intermediate storage location for the cartridges 26, accumulating as and when they are collected at workstations 1 and returned at the end of work.
A titre d'exemple, un stockage par colonnes ou s'empilent les cartouches 26 est montre en figure 1. Pour la récupération des cartouches 26 depuis le centre de stockage 2, une station de reddition 3 est présente.By way of example, storage in columns where the cartridges 26 stack up is shown in FIG. 1. For the recovery of the cartridges 26 from the storage center 2, a surrender station 3 is present.
D'autres zones emettrices ou réceptrices peuvent être constituées. Ainsi une zone d'approvisionnement 4 est figurée a la figure 2. Une station d'ecnange 8 qui ressort également de la figure 2 peut encore être formée. De façon courante, la circulation des cartouches 26 s'effectue de façon pneumatique. Pour ce faire, des moyens d'aspiration ou de soufflerie sont présents afin de générer un flux d'air dans le circuit de convoyage 14.Other transmitting or receiving zones can be formed. Thus a supply area 4 is shown in Figure 2. An exchange station 8 which also emerges from Figure 2 can still be formed. Commonly, the circulation of the cartridges 26 is carried out pneumatically. To do this, suction or blower means are present in order to generate an air flow in the conveying circuit 14.
Pour un bon fonctionnement du dispositif, il faut pouvoir faire varier le sens du flux d'air suivant le chemin que la cartouche doit suivre.For a good functioning of the device, it is necessary to be able to vary the direction of the air flow according to the path that the cartridge must follow.
En outre, il s'agit de générer un flux d'une puissance plus importante pour le transfert simultané de plusieurs cartouches 26 que pour le convoyage individuel des cartouches. Pour y parvenir, l'invention propose de façon avantageuse des moyens de variation du flux 6. Ils ont pour fonctior de faire varier non seulement le sens du flux mais aussi sa puissance . Selon un mode préfère de réalisation, les moyens de variation du flux 6 se présentent comme illustres en figure 3.In addition, it involves generating a flow of greater power for the simultaneous transfer of several cartridges 26 than for the individual conveying of the cartridges. To achieve this, the invention advantageously provides means for varying the flow 6. Their function is to vary not only the direction of the flow but also its power. According to a preferred embodiment, the means for varying the flow 6 appear as illustrated in FIG. 3.
Sur cette figure, une turbine 7 de conception connue fait office de moyens de soufflerie ou d'aspiration. Elle comprend une voie d'entrée du flux 42 et une voie de sortie 43. Ces deux voies 42,43 sont reliées a un boîtier 23 constituant le corps des moyens de variation du flux 6.In this figure, a turbine 7 of known design acts as blower or suction means. It comprises an inlet channel for the flow 42 and an outlet channel 43. These two channels 42, 43 are connected to a housing 23 constituting the body of the means for varying the flow 6.
Ce boîtier comporte également une sortie 17 a 1 ' atmosphère .This housing also has an outlet 17 to 1 atmosphere.
Enfin, le boîtier 23 communique avec les voies de soufflerie 15 et d'aspiration 16 constituant la partie amont du circuit de convoyage 14.Finally, the housing 23 communicates with the blower 15 and suction 16 channels constituting the upstream part of the conveying circuit 14.
Le boîtier 23 renferme d'autre part des moyens de mise en communication variable des voies 15, 16, 42, 43. Ils comprennent d'abord un disque 24 rotatif qui comporte une ouverture 25. Cette ouverture 25, comme cela ressort de la figure 3 permet, lorsque le disque 24 est correctement positionne, de mettre en communication deux voies : soit les voies d'entrée 42 et d'aspiration 16, soit les voies de sortie 43 et de soufflerie 15. Pour le reste de sa surface, le disque 24 assure la fermeture etanche a l'air des voies 15,16.The housing 23 also contains means for bringing the channels 15, 16, 42, 43 into variable communication. They firstly comprise a rotary disc 24 which has an opening 25. This opening 25, as can be seen in the figure 3 allows, when the disc 24 is correctly positioned, to connect two channels: either the inlet 42 and suction 16 channels, or the outlet 43 and blower 15. For the rest of its surface, the disc 24 ensures the airtight closure of the tracks 15,16.
On comprend aisément que selon la position du disque 24, un flux d'aspiration ou de soufflerie est génère dans le circuit de convoyage 14. Ce flux peut aussi être nul si l'ouverture 25 n'est en vis a vis d'aucune voie 15, 16, 42,It is easily understood that, depending on the position of the disc 24, a suction or blower flow is generated in the conveying circuit 14. This flow can also be zero if the opening 25 is not opposite any path. 15, 16, 42,
43.43.
Enfin, sa puissance est variable depuis une valeur maximale lorsque l'ouverture 25 est exactement au regard des voies 15,43; 16,42, jusqu'à des valeurs dégressives lorsque l'ouverture 25 ne communique que partiellement avec les voiesFinally, its power is variable from a maximum value when the opening 25 is exactly with regard to the tracks 15,43; 16.42, up to declining values when opening 25 communicates only partially with the channels
15,43 ; 16,42.15.43; 16.42.
On notera qu'un silencieux 20 de conception courante peut être inséré en aval des moyens de variation de flux 6 pour diminuer les nuisances sonores.It will be noted that a silencer 20 of current design can be inserted downstream of the flow variation means 6 to reduce the noise pollution.
Les moyens de soufflerie ou d'aspiration et les moyens de variations du flux 6 ainsi présentés permettent le convoyage de toute cartouche dans le circuit de convoyage 14.The blower or suction means and the flow variation means 6 thus presented allow the conveying of any cartridge into the conveying circuit 14.
Selon un mode préféré de réalisation, ce circuit de convoyage 14 comporte une ligne de transit 13. La formation de cette ligne évite la multiplication des lignes distinctes à toutes les liaisons nécessaires. La ligne de transit 13 assure la mise en instance des cartouches 26 avant leur orientation vers l'emplacement souhaité. Pour y parvenir, elle coopère avec un aiguilleur 9 apte à mettre en communication la ligne de transit 13 avec une autre ligne du circuit de convoyage 14.According to a preferred embodiment, this conveying circuit 14 includes a transit line 13. The formation of this line prevents the multiplication of separate lines at all the necessary connections. The transit line 13 ensures the storage of the cartridges 26 before their orientation towards the desired location. To achieve this, it cooperates with a switcher 9 able to put the transit line 13 into communication with another line of the conveying circuit 14.
Il pourra s'agir de la ligne de stockage 11 (vers le centre de stockage 2), de la ligne de reddition 12 (vers la station de reddition 3), de la ligne d'approvisionnement 18It could be storage line 11 (to storage center 2), surrender line 12 (to surrender station 3), supply line 18
(vers la zone d'approvisionnement 4), de la ligne d'échange 19(to supply area 4), from exchange line 19
(vers la station d'échange 8) et de la ligne principale 5(to exchange station 8) and main line 5
(vers les postes de travail 1).(to workstations 1).
A titre d'exemple, on décrit ci-après le convoyage d'une cartouche 26 depuis un poste de travail 1 jusqu'au centre de stockage 2 :By way of example, the following describes the conveying of a cartridge 26 from a work station 1 to the storage center 2:
1° Grâce aux moyens de variation du flux 6, une aspiration est engendrée dans la ligne principale 5,1 ° Thanks to the means for varying the flow 6, a suction is generated in the main line 5,
2° Par le biais de l'aiguilleur 9 commandé à cet effet, la cartouche 26 parvient dans la ligne de transit 13.2 ° By means of the switcher 9 controlled for this purpose, the cartridge 26 reaches the transit line 13.
3° les moyens de variation de flux 6 sont commandés pour inverser le sens du flux alors que l'aiguilleur 9 met en liaison la ligne de transit 13 et la ligne de stockage 11.3 ° the flow variation means 6 are controlled to reverse the direction of the flow while the switch 9 connects the transit line 13 and the storage line 11.
4° La cartouche parvient au centre de stockage 2. Tout autre circuit de cartouche peut être réalisé suivant ce principe de fonctionnement.4 ° The cartridge reaches storage center 2. Any other cartridge circuit can be produced according to this operating principle.
Pour des convoyages de plusieurs cartouches (notamment pour le transfert depuis le centre de stockage 2 jusqu'à la station de reddition 3), la pleine puissance sera utiliséeFor conveying several cartridges (in particular for transfer from storage center 2 to surrender station 3), full power will be used
-_ alors que l_e_s moyens _ de variation de flux 6 fixeront une puissance inférieure pour des cartouches individuelles.-_ while l_e_s _ of flow variation 6 will set a lower power for individual cartridges.
D'autres modes de réalisation sont présentés ci-après.Other embodiments are presented below.
Ainsi, à l'exclusion du transfert d'une série de cartouches 26 du centre de stockage 2 vers la station de reddition 3, le freinage d'une cartouche dans la ligne de transit 13 jusqu'à son arrêt est réalisé par compression d'air, en bloquant la circulation de l'air par fermeture des moyens de variation du flux 6 immédiatement après le passage de l'aiguilleur 9.Thus, excluding the transfer of a series of cartridges 26 from the storage center 2 to the surrender station 3, the braking of a cartridge in the transit line 13 until it stops is achieved by compression of air, by blocking the circulation of air by closing the flow variation means 6 immediately after the switch 9 has passed.
Dans un mode préféré, la station de reddition 3 est située entre les moyens de variation du flux 6 et la ligne principale 13. Cela est présenté en figure 2.In a preferred mode, the rendering station 3 is located between the means for varying the flow 6 and the main line 13. This is presented in FIG. 2.
De cette façon, il n'est plus nécessaire d'employer une ligne de reddition 12.In this way, it is no longer necessary to use a reporting line 12.
Deux modes de fonctionnement de la station de reddition sont exposés ci-après.Two operating modes of the surrender station are set out below.
Le premier d'entre eux est illustré en figure 2 dans le mode préféré où la station de reddition 3 est intercalée entre les moyens de variation de flux 6 et la ligne de transit 13.The first of them is illustrated in FIG. 2 in the preferred mode where the rendering station 3 is interposed between the flow variation means 6 and the transit line 13.
Dans ce cadre, la turbine 7 aspire la série de cartouches à convoyer depuis le centre de stockage 2, à travers l'aiguilleur 9 et l'aiguilleur de reddition 28 présent au niveau de la station de reddition 3. Cet aiguilleur 28 est visible aux figures 6 et 7.In this context, the turbine 7 sucks the series of cartridges to be conveyed from the storage center 2, through the switcher 9 and the surrender switcher 28 present at the level of the surrender station 3. This switcher 28 is visible to the Figures 6 and 7.
L'aspiration se prolonge pendant un temps suffisamment long pour permettre à toutes les cartouches 26 de dépasser la ligne de transit 13 et l'aiguilleur 28. Elles sont successivement freinées dans un tube d'amortissement 10. L'aiguilleur de reddition 28 assure la communication du tube d'amortissement 10 avec la ligne de transit 13 ou la ligne de sortie 27 vers le panier de réception 44.The suction is prolonged for a time long enough to allow all the cartridges 26 to exceed the transit line 13 and the switch 28. They are successively braked in a damping tube 10. The surrender switch 28 ensures the communication of the damping tube 10 with the transit line 13 or the outlet line 27 to the receiving basket 44.
Le tube d'amortissement 10 est ferme a son extrémité supérieure et est relie a une ou deux voies de passage 29,30 au flux débouchant sur un conduit 31 relie aux moyens de variation de flux 6.The damping tube 10 is closed at its upper end and is connected to one or two passageways 29, 30 to the flow leading to a conduit 31 connected to the flow variation means 6.
La première cartouche 26 aspirée dans le tube d'amortissement 10 se bloque au niveau de la voie de passage 30 comprimant le volume d'air de l'extrémité du tube 10 pour se freiner.The first cartridge 26 sucked into the damping tube 10 is blocked at the level of the passageway 30 compressing the volume of air from the end of the tube 10 to brake.
Les cartouches 26 suivantes sont aspirées, le flux circulant par la voie de passage 29. Elles s'empilent sous la première cartouche. Une cellule 45 vérifie le passage des cartouches 26. Quand elles sont toutes parvenues au tube d'amortissement 10, l'aiguilleur 28 connecte ce tube 10 a la ligne de sortie 27. Les cartouches descendent par gravité vers le panier 44.The following cartridges 26 are aspirated, the flow flowing through the passageway 29. They stack under the first cartridge. A cell 45 checks the passage of the cartridges 26. When they have all reached the damping tube 10, the switch 28 connects this tube 10 to the outlet line 27. The cartridges descend by gravity to the basket 44.
Un autre mode de réalisation de la station de reddition, voisin du premier peut être mis en œuvre, notamment dans le cas ou la station de reddition n'est pas intercalée entre la ligne de transit 13 et les mo\ens de variation du flux 6 (cas illustre en figure 1) .Another embodiment of the surrender station, close to the first, can be implemented, in particular in the case where the surrender station is not interposed between the transit line 13 and the flow variation methods 6 (case illustrated in Figure 1).
Dans cette autre version, la station de reddition 3 est reliée a la ligne de reddition 12 et se présente sous la forme d'un coffre 46 muni d'une porte 47. A l'extrémité supérieure de la ligne de reddition 12, un entraînement, notamment par une roue en caoutchouc motorisée assure le freinage des cartouches, puis leur entraînement vers le coffre 46. L'operateur peut alors les collecter par ouverture de la porte 47.In this other version, the surrender station 3 is connected to the surrender line 12 and is in the form of a trunk 46 provided with a door 47. At the upper end of the surrender line 12, a drive , in particular by a motorized rubber wheel ensures the braking of the cartridges, then their drive towards the trunk 46. The operator can then collect them by opening the door 47.
Cette variante de la station de reddition 3 est présentée en fîqure 8. Dans le mode de réalisation illustre a la figure 3, des volumes tampons 21,22 sont réalises dans les voies d'entrée 42 et de sortie 43 du flux. Ils sont utiles lorsque ces voiesThis variant of the surrender station 3 is presented in FIG. 8. In the embodiment illustrated in FIG. 3, buffer volumes 21, 22 are produced in the inlet 42 and outlet 43 paths of the flow. They are useful when these pathways
42,43 sont brusquement obstruées suivant la rotation du disque 2442.43 are suddenly obstructed according to the rotation of the disc 24
Les volumes tampon 21,22 diminuent les effets thermiques et mécaniques par leur effet capacitif d'absorption.The buffer volumes 21, 22 reduce the thermal and mechanical effects by their capacitive absorption effect.
A titre d'exemple, leur volume sera égal, au minimum, au débit de la turbine 7 pendant environ une seconde ; soit, pour une turbine 7 de capacité d'aspiration de 400 m3/h, une longueur de 10m en tube de diamètre 110mm.By way of example, their volume will be at least equal to the flow rate of the turbine 7 for approximately one second; or, for a turbine 7 with a suction capacity of 400 m 3 / h, a length of 10 m in a 110 mm diameter tube.
Dans un autre mode de réalisation, le dispositif intègre une zone d'approvisionnement 4 en cartouches 26 vides. La formation d'une telle zone ressort de la figure 2. La zone d'approvisionnement 4 est reliée a l'aiguilleur 9 par une ligne d'approvisionnement 18.In another embodiment, the device integrates a supply zone 4 of empty cartridges 26. The formation of such a zone is shown in FIG. 2. The supply zone 4 is connected to the switch 9 by a supply line 18.
La figure 9 montre que la zone d'approvisionnement 4 comprend d'abord une colonne 32. Celle-ci n'est pas forcement verticale. Elle comporte, a une extrémité, une ouverture 36, éventuellement associée a un couvercle, pour l'introduction des cartouches 26 par un operateur.Figure 9 shows that the supply area 4 first comprises a column 32. This is not necessarily vertical. It comprises, at one end, an opening 36, possibly associated with a cover, for the introduction of the cartridges 26 by an operator.
Dans une forme préférée de l'invention, l'ouverture 36 se trouve a proximité de la station de reddition 3, de sorte que l'operateur, après avoir réceptionne sa cartouche pleine a la station de redditon 3, la vide et la reintroduit immédiatement dans l'ouverture 32 pour sa mise a disposition dans le convoyage .In a preferred form of the invention, the opening 36 is located near the surrender station 3, so that the operator, after having received his full cartridge at the reddit station 3, empties it and reintroduces it immediately in the opening 32 for its provision in the conveyance.
A l'autre extrémité, la colonne 32 débouche sur des moyens de libération 33 de cartouches vers la ligne d'approvisionnement 18.At the other end, the column 32 leads to means 33 for releasing cartridges to the supply line 18.
A titre non limitatif, ces moyens de libération 33 pourront comprendre des moyens d'entraînement d'une cartouche 26 sous forme d'ensembles motorises a courroies 34 ou a galet s 'appliquant sur la cartouche 26. On a schématisé en figure 9 une courroie 34 monte sur deux axes de rotation 35 et actionnée par un moteur 37. Des moyens de suspension 38, tels un ressort assure la variation latérale de position d'un des axes de rotation 35. On a aussi représenté un détecteur de présence 39 de conception courante apte à détecter l'arrivée d'une cartouche 26 dans l'entrée de la ligne d'approvisionnement 18.Without limitation, these release means 33 may include means for driving a cartridge 26 in the form of motorized belts 34 or roller assemblies applied to the cartridge 26. There is shown diagrammatically in FIG. 9 a belt 34 mounted on two axes of rotation 35 and actuated by a motor 37. Suspension means 38, such as a spring ensures the lateral position variation of one of the axes of rotation 35. We also have shown a presence detector 39 of current design capable of detecting the arrival of a cartridge 26 in the inlet of the supply line 18.
Lorsqu'une cartouche 26 est complètement introduite dans cette ligne 18, l'information issue du détecteur de présence 39 engendre l'ouverture d'une soupape 41. Cette ouverture permet une entrée d'air 40 pour l'aspiration de la cartouche en instance.When a cartridge 26 is completely inserted into this line 18, the information from the presence detector 39 generates the opening of a valve 41. This opening allows an air inlet 40 for the suction of the cartridge in progress .
Dans le même temps, les ensembles d'entraînement sont inverses de façon a retenir les autres cartouches 26 présentes dans la colonne 32, comme illustré en figure 9.At the same time, the drive assemblies are reversed so as to retain the other cartridges 26 present in column 32, as illustrated in FIG. 9.
Dans la station d'échange 8 constituée pour une communication avec les postes de travail, le convoyage des cartouches 26 s'effectue, par un transit dans la ligne principale puis par une inversion du flux pour orienter, par l'aiguilleur 9, la cartouche 26 vers l'emplacement souhaite. Le même trajet peut être suivi en sens inverse par les cartouches 26 pour recevoir a la station d'échange des envois des postes de travail 1, là encore, par un transit dans le ligne principale 5 puis par une inversion de flux pour orienter, par l'aiguilleur 9, la cartouche 26 vers la station principale .In the exchange station 8 formed for communication with the workstations, the cartridges are conveyed 26, by a transit in the main line then by an inversion of the flow to orient, by the switch 9, the cartridge 26 to the desired location. The same route can be followed in the opposite direction by the cartridges 26 to receive at the exchange station consignments of workstations 1, here again, by a transit in the main line 5 then by a reversal of flow to orient, by the switch 9, the cartridge 26 to the main station.
L'ensemble du dispositif peut être automatisé par des moyens courants d'automatisation.The entire device can be automated by common means of automation.
On décrit ci-après un mode particulier de réalisation du centre de stockage 2. Ce dernier est raccorde au reste du circuit de convoyage par une ligne de stockage 11.A particular embodiment of the storage center 2 is described below. The latter is connected to the rest of the conveying circuit by a storage line 11.
Comme visible en figure 10, la ligne de stockage 11 est raccordée a l'entrée 51 du centre de stockage 2. Cette entrée 51 se situe a une extrémité d'un tuvau coude 50 L'autre extrémité du tuyau 50 débouche en partie supérieure d'un barillet 48. Cette extrémité forme la sortie 52 d'un sélecteur. Ce dernier est constitue d'une pluralité de tubes cylindriques 49 aptes a recevoir des cartouches en superposition Les tubes 49 sont parallèles et s'organisent suivant un cercle, pour former le barillet 48.As shown in FIG. 10, the storage line 11 is connected to the inlet 51 of the storage center 2. This inlet 51 is located at one end of a bent pipe 50 The other end of the pipe 50 opens out at the top of a barrel 48. This end forms the outlet 52 of a selector. The latter consists of a plurality of cylindrical tubes 49 able to receive cartridges in superposition. The tubes 49 are parallel and are organized in a circle, to form the barrel 48.
La sortie 52 peut être positionnée en regard de l'embouchure du tube 49 desiree. Pour ce faire, le tuyau coude 50 est mu en rotation selon un axe correspondant a celui du barillet 48.The outlet 52 can be positioned opposite the mouth of the desired tube 49. To do this, the elbow pipe 50 is rotated along an axis corresponding to that of the barrel 48.
La jonction etanche de la sortie 52 et du tube 49 s'effectue par un joint 56. La mobilité en rotation du tuyau 50 du sélecteur peut être opérée par motorisation.The sealed connection of the outlet 52 and the tube 49 is effected by a seal 56. The rotational mobility of the pipe 50 of the selector can be operated by motorization.
Les tubes 49, dont la capacité peut varier de 1 a 5 cartouches suivant les besoins de stockage, sont maintenus en position grâce a une gorge ou lamage du diamètre du tube réalisée sur chacune des plaques inférieure et intermédiaire.The tubes 49, the capacity of which can vary from 1 to 5 cartridges depending on storage needs, are held in position by means of a groove or countersinking of the diameter of the tube produced on each of the lower and intermediate plates.
Le tube 49 est ainsi positionne et sans aucune déformation du tube pour éviter tout risque de coincement des cartouches.The tube 49 is thus positioned and without any deformation of the tube to avoid any risk of jamming of the cartridges.
Afin de permettre l'aspiration des cartouches lors d'une opération de reddition c'est-a-dire de restitution des cartouches stockées dans le centre , une soupape 53 est placée entre le tube 49 et la plaque inférieure 60. Cette plaque inférieure 60 est fixée a la partie supérieure du centre par 4 montants garantissant la rigidité et la robustesse de la partie stockage de l'installation. Dans un but d'amélioration de la sécurité des cartouches stockées, des capteurs 59 peuvent être places a l'intérieur du stockeur, en cas de tentative de dépose des carters de protection sans autorisation, une alarme peut être activée ou déclenchée . Le centre de stockage est équipé, en partie haute, d'un sélecteur pivotant qui assure l'orientation des cartouches vers la zone de stockage constituée par des tubes 49.In order to allow the suction of the cartridges during a surrender operation, that is to say the return of the cartridges stored in the center, a valve 53 is placed between the tube 49 and the lower plate 60. This lower plate 60 is fixed to the upper part of the center by 4 uprights guaranteeing the rigidity and robustness of the storage part of the installation. In order to improve the security of the stored cartridges, sensors 59 can be placed inside the storage device, in the event of an attempt to remove the protective casings without authorization, an alarm can be activated or triggered. The storage center is equipped, in the upper part, with a pivoting selector which ensures the orientation of the cartridges towards the storage area constituted by tubes 49.
La rotation du tuyau 50 de sélection est assurée par un moteur 55 alimenté et géré par une carte électronique assurant tout lien (alimentation, communication et gestion du moteur), avec les autres éléments du système de convoyage pneumatique.The rotation of the selection pipe 50 is ensured by a motor 55 supplied and managed by an electronic card ensuring any link (supply, communication and management of the engine), with the other elements of the pneumatic conveying system.
Le tuyau 50 est positionné entre la plaque supérieure 58 et la plaque intermédiaire 61 qui sont reliées par 4 petits montants .The pipe 50 is positioned between the upper plate 58 and the intermediate plate 61 which are connected by 4 small uprights.
Le passage des cartouches est vérifié au moyen d'un détecteur 57 placé à proximité de l'entrée 51 qui permet d'éviter une arrivée brutale d'une cartouche dans le tube 49 celle-ci pouvant peser jusqu'à 2,5 kg.The passage of the cartridges is checked by means of a detector 57 placed near the inlet 51 which makes it possible to avoid a sudden arrival of a cartridge in the tube 49 which can weigh up to 2.5 kg.
Cette détection informe et ordonne l'arrêt de la soufflerie .This detection informs and orders the wind tunnel to stop.
La cartouche est alors freinée pneumatiquement par la compression du volume d'air contenu dans le tube 49 et dans le tuyau 50 et elle descend par gravité dans le tube 49. The cartridge is then pneumatically braked by the compression of the volume of air contained in the tube 49 and in the tube 50 and it descends by gravity into the tube 49.
