Description

La présente invention concerne un dispositif pour l'admission contrôlée d'une poudre nocive dans une boíte.The present invention relates to a device for admission controlled of a harmful powder in a box.

Dans un certain nombre d'industries, on produit des poudres qu'il convient de conditionner dans des boítes. Ces poudres sont souvent nocives dans la mesure où d'une part elles peuvent être dangereuses pour l'entourage et où d'autre part elles peuvent présenter un pouvoir abrasif élevé.In a number of industries, powders are produced that should be packaged in boxes. These powders are often harmful insofar as on the one hand they can be dangerous for the entourage and where on the other hand they can present a power high abrasive.

Il convient donc de pouvoir disposer d'un dispositif permettant l'admission contrôlée d'une poudre dans une boíte, c'est-à-dire dans un conteneur permettant le conditionnement de ladite poudre. Il convient en outre de mettre au point une procédure, c'est-à-dire un procédé, permettant de réaliser, dans des conditions de sécurité convenables, le remplissage de ladite boíte. Ce sont là les buts de la présente invention.It is therefore advisable to have a device allowing the controlled admission of a powder in a box, that is to say in a container for packaging said powder. It should be in addition to developing a procedure, that is to say a process, allowing to carry out, under suitable security conditions, the filling of said box. These are the aims of the present invention.

Le dispositif selon l'invention est caractérisé en ce qu'il comporte :

  • un corps de forme générale cylindrique dont la partie inférieure ouverte se termine par une jupe d'étanchéité, ledit corps étant relié à un tuyau d'arrivée de poudre, à un tuyau d'extraction des gaz, et à un tube supérieur comportant un dispositif magnétique commandant un clapet mobile dans ledit corps et apte à coopérer avec ladite jupe d'étanchéité,
  • un carter fixé sur la partie inférieure dudit corps ouvert à sa partie centrale pour permettre le passage de la boíte et comportant un dispositif mobile escamotable assurant la préhension et le transfert du couvercle de la boíte,
  • des moyens de détection de la quantité de poudre dans la boíte,
  • et au moins un circuit de ventilation assurant au niveau du tour de l'ouverture dudit carter et/ou au niveau de ladite jupe d'étanchéité une évacuation de la partie de ladite poudre qui se situerait à ces niveaux.
The device according to the invention is characterized in that it comprises:
  • a generally cylindrical body whose open lower part ends in a sealing skirt, said body being connected to a powder inlet pipe, to a gas extraction pipe, and to an upper tube comprising a device magnetic controlling a movable valve in said body and able to cooperate with said sealing skirt,
  • a casing fixed on the lower part of said body open at its central part to allow the passage of the box and comprising a retractable mobile device ensuring the gripping and the transfer of the cover of the box,
  • means for detecting the quantity of powder in the box,
  • and at least one ventilation circuit ensuring at the level of the opening of said casing and / or at the level of said sealing skirt an evacuation of the part of said powder which would be located at these levels.

L'invention sera mieux comprise en se référant à l'exemple ci-après de réalisation, cet exemple étant illustré par la figure unique qui est une vue, en coupe longitudinale, du dispositif.The invention will be better understood by referring to the example below of realization, this example being illustrated by the single figure which is a view, in longitudinal section, of the device.

Sur cette figure, on a représenté :

  • en 1 le corps de l'appareil ; ce corps a sensiblement une forme cylindrique, et un diamètre suffisant, en partie basse, pour que la boíte y soit admise ; il comporte, autour de sa partie basse 2, une jupe 3 permettant d'assurer d'une part en coopération avec le haut de la boíte réceptrice et d'autre part en coopération avec un clapet mobile une certaine étanchéité,
  • en 4 un tuyau par lequel s'effectue l'arrivée de la poudre ; il est clair que l'inclinaison dudit tuyau par rapport à l'horizontale doit être choisie de façon à permettre un écoulement régulier de la poudre,
  • en 5 un tuyau pour l'extraction des gaz par aspiration ; ce tuyau est muni, à l'intérieur, d'une bougie de filtration 15 et, à son extrémité, le tuyau 5 se prolonge par le conduit de sortie 5a relié à des moyens d'extraction et de traitement des gaz,
  • en 6 un tube supérieur fermé, disposé au-dessus du corps 1 et solidaire de celui-ci,
  • en 7 un clapet mobile apte à coulisser dans le corps 1 et solidaire, par l'intermédiaire d'une tige de liaison surmontant le clapet, d'un noyau magnétique 9 coulissant dans le tube 6 et permettant, grâce à l'action d'un aimant 8 extérieur audit tube 6, la commande de la position dudit clapet 7 à l'intérieur du corps 1. La surface inférieure du clapet mobile est constituée d'une portion de sphère (ou de tore) annulaire et d'une surface plane terminale; cette portion de sphère est d'une dimension telle qu'elle s'adapte exactement à la surface intérieure de la jupe formant siège 3 pour assurer à ce niveau une bonne étanchéité, le clapet 7 présentant un diamètre maximum, au niveau de la portion de sphère précitée, qui est supérieur au diamètre d'ouverture de la jupe 3, ce dernier étant lui-même légèrement inférieur à celui de l'ouverture de la boíte de façon à assurer que la poudre glissant sur la face interne de la jupe pénètre dans la boíte (l'extrémité libre annulaire de la jupe 3 est en contact et/ou en appui avec le bord libre de la paroi interne de la boíte 19),
  • en 10 un carter qui est fixé à la partie inférieure du corps 1 ; ce carter a par exemple une forme générale rectangulaire dont la largeur est supérieure au diamètre de la boíte; ce carter comporte en son centre une ouverture suffisante pour laisser passer la boíte ; à l'intérieur de ce carter, on dispose un dispositif mobile 11 qui peut être déplacé, par translation sur toute la longueur du carter ; le déplacement de ce dispositif mobile 11 est commandé de l'extérieur du carter par un dispositif (non représenté en détail). Ce dispositif mobile 11 comporte une cavité pour y loger le couvercle 12 de la boíte. La préhension du couvercle est assurée par aspiration au moyen du tuyau 16. Ce dispositif mobile comporte également une ouverture 17 dont le diamètre est au moins égal à celui de la boíte,
  • en 14 deux circuits de ventilation ; l'un de ces circuits (141) comporte une entrée d'air disposée sur le pourtour de la boíte lorsque celle-ci est mise en place, cet air provenant de l'environnement du dispositif, par exemple l'enceinte de confinement, telle qu'une boíte à gants dans laquelle le dispositif est installé ; le deuxième circuit (142) comporte une entrée d'air située au-dessus de la jupe 3, cet air provenant également de l'environnement du dispositif ;ces deux circuits comportent une sortie d'air, qui peut être commune et qui a été représentée en 18, laquelle est avantageusement reliée à des moyens d'aspiration et de traitement des gaz extraits susceptibles de contenir de la poudre,
  • et un détecteur 13 rétractable, connu en lui-même, permettant de détecter le niveau de la poudre introduite dans la boíte lorsque ce niveau atteint une hauteur prédéterminée.
In this figure, we have represented:
  • in 1 the body of the device; this body has a substantially cylindrical shape, and a sufficient diameter, in the lower part, for the box to be admitted; it includes, around its lower part 2, a skirt 3 making it possible on the one hand to ensure, in cooperation with the top of the receiving box and, on the other hand, in cooperation with a movable valve, a certain seal,
  • in 4 a pipe through which the arrival of the powder takes place; it is clear that the inclination of said pipe relative to the horizontal must be chosen so as to allow a uniform flow of the powder,
  • at 5 a pipe for the extraction of gases by suction; this pipe is provided, inside, with a filter candle 15 and, at its end, the pipe 5 is extended by the outlet pipe 5a connected to gas extraction and treatment means,
  • at 6 a closed upper tube, disposed above the body 1 and integral with the latter,
  • at 7 a movable valve capable of sliding in the body 1 and secured, by means of a connecting rod surmounting the valve, of a magnetic core 9 sliding in the tube 6 and allowing, thanks to the action of a magnet 8 outside said tube 6, controlling the position of said valve 7 inside the body 1. The lower surface of the movable valve consists of a portion of annular sphere (or torus) and a flat surface terminal; this portion of the sphere is of a size such that it adapts exactly to the interior surface of the skirt forming the seat 3 to ensure good sealing at this level, the valve 7 having a maximum diameter, at the portion of aforementioned sphere, which is greater than the opening diameter of the skirt 3, the latter itself being slightly smaller than that of the opening of the box so as to ensure that the powder sliding on the internal face of the skirt enters the box (the annular free end of the skirt 3 is in contact and / or in abutment with the free edge of the internal wall of the box 19),
  • at 10 a casing which is fixed to the lower part of the body 1; this casing has for example a generally rectangular shape whose width is greater than the diameter of the box; this housing has in its center an opening sufficient to let the box pass; inside this casing, there is a mobile device 11 which can be moved, by translation over the entire length of the casing; the movement of this mobile device 11 is controlled from the outside of the casing by a device (not shown in detail). This mobile device 11 includes a cavity for housing the cover 12 of the box. The grip of the cover is ensured by suction by means of the pipe 16. This mobile device also includes an opening 17 whose diameter is at least equal to that of the box,
  • at 14 two ventilation circuits; one of these circuits (14 1 ) has an air inlet disposed around the periphery of the box when it is in place, this air coming from the environment of the device, for example the confinement enclosure, such as a glove box in which the device is installed; the second circuit (14 2 ) has an air inlet located above the skirt 3, this air also coming from the environment of the device; these two circuits have an air outlet, which can be common and which has shown in 18, which is advantageously connected to means for suction and treatment of the extracted gases capable of containing powder,
  • and a retractable detector 13, known in itself, making it possible to detect the level of the powder introduced into the can when this level reaches a predetermined height.

Le dispositif selon l'invention est utilisé en mettant en oeuvre le procédé dont on va décrire ci-après les principales séquences.The device according to the invention is used by implementing the process whose main sequences will be described below.

Dans une première étape, le clapet mobile 7 reposant sur la jupe 3, le détecteur 13 remonté et un couvercle 12 ayant été fixé en dessous du dispositif mobile 11, la boíte 19 est mise en place. Cette mise en place s'effectue en entrant le haut de ladite boíte par l'ouverture du carter (dans lequel le dispositif mobile 11 a été convenablement positionné) jusqu'à ce que le bord supérieur de ladite boíte 19 vienne en appui contre la face extérieure de la jupe 3 et comprime le ressort 20. Dans cette position , la boíte 19 et la jupe 3 referment la partie basse 2 du corps 1 et participent au confinement dynamique du dispositif par rapport à l'enceinte de confinement, comme il sera décrit plus en détail plus loin.In a first step, the movable valve 7 resting on the skirt 3, the detector 13 reassembled and a cover 12 having been fixed in below the mobile device 11, the box 19 is put in place. This bet in place is done by entering the top of said box through the opening of the housing (in which the mobile device 11 has been suitably positioned) until the upper edge of said box 19 comes in press against the outer face of the skirt 3 and compresses the spring 20. In this position, the box 19 and the skirt 3 close the lower part 2 of the body 1 and participate in the dynamic confinement of the device with respect to at the containment, as will be described in more detail later.

Dans une deuxième étape, le clapet mobile 7 est remonté au-dessus du niveau d'arrivée du tuyau 4.In a second step, the movable valve 7 is raised above the inlet level of the pipe 4.

Dans une troisième étape, le détecteur 13 est descendu dans le corps 1 et la poudre est admise, par ledit tuyau 4, dans la boíte 19.In a third step, the detector 13 descended into the body 1 and the powder is admitted, through the said pipe 4, into the box 19.

Lorsque le détecteur 13 de l'arrivée de poudre signale la fin du remplissage de la boíte 19, l'introduction de poudre par le tuyau 4 est stoppée, le détecteur 13 est rétracté selon son axe, le clapet mobile 7 est redescendu jusque sur la jupe 3 pour confiner l'intérieur du corps 1, ladite boíte est alors descendue jusqu'à ce que le bord supérieur de la boíte soit au niveau du plan inférieur du carter 10. Le dispositif mobile 11 situé à l'intérieur du carter fait alors l'objet d'une translation qui amène le couvercle 12 au-dessus de la boíte puis ce couvercle 12 est désolidarisé d'avec le dispositif mobile 11 pour être déposé sur la boíte. La boíte, avec son couvercle, est alors évacuée.When the powder arrival detector 13 signals the end of the filling of the box 19, the introduction of powder through the pipe 4 is stopped, the detector 13 is retracted along its axis, the movable valve 7 is down to the skirt 3 to confine the interior of the body 1, said the box is then lowered until the upper edge of the box is at the lower plane of the housing 10. The mobile device 11 located at the inside of the housing is then the subject of a translation which brings the cover 12 above the box then this cover 12 is detached with the mobile device 11 to be placed on the box. The box, with its cover is then removed.

Il va de soi que, durant toutes ces opérations, le dispositif de ventilation fonctionne en continu de façon à assurer une sécurité maximum. Pour cela, ledit circuit de ventilation comporte les moyens d'aspiration précités (5a, 18) reliés à une unité de traitement des gaz susceptibles de contenir de la poudre, cette unité de traitement constituant avantageusement en outre, pour le dispositif selon l'invention, des moyens plaçant l'intérieur dudit corps 1 en dépression par rapport à l'extérieur.It goes without saying that, during all these operations, the ventilation operates continuously to ensure safety maximum. For this, said ventilation circuit includes the means aforementioned suction lines (5a, 18) connected to a gas treatment unit likely to contain powder, this processing unit advantageously further constituting, for the device according to the invention, means placing the interior of said body 1 in depression relative to outside.

Ainsi, on comprend que trois situations sont possibles :

  • soit le clapet 7 referme le corps 1 en étant en appui sur la jupe 3 (cas non représenté), une étanchéité dynamique étant assurée au niveau des jeux subsistant entre la jupe 3 et la partie basse 2 du corps 1, d'une part, et entre le dispositif mobile 11 (position fermée non représentée) et l'ouverture inférieure du carter 10, d'autre part, du fait de la dépression continuellement établie entre l'intérieur et l'extérieur du dispositif grâce à l'aspiration, par les conduits 5a et 18, d'un courant d'air ayant circulé, depuis les entrées d'air 141 et 142, à l'emplacement des jeux précités afin d'en évacuer la poudre qui aurait pu s'y trouver,
  • soit la boíte 19 est en cours d'accostage sur l'ouverture du carter 10 et sur la jupe 3, le clapet 7 étant toujours en position basse, l'entrée d'air 141 permettant d'éviter toute sortie de poudre hors du dispositif au niveau de l'ouverture du carter (première étape précitée) grâce au phénomène d'étanchéité dynamique qui vient d'être décrit,
  • soit la boíte 19 est montée sur la jupe 3 (deuxième et troisième étapes précitées), le clapet 7 étant en position haute (voir figure), et le confinement dynamique précité est maintenu, pour éviter toute contamination par sortie non contrôlée de poudre en dehors du dispositif. En effet, l'ensemble de ventilation formé par les circuits d'entrée d'air (141 et 142), les jeux existant entre la jupe 3 et la partie basse 2 du corps 1 (voir les flèches en traits pointillés qui représentent le passage de l'air de ventilation au niveau de ces jeux) et les conduits de sortie (5a et 18) placent le volume intérieur du corps 1 et de la boíte 19 en dépression par rapport à l'extérieur afin de minimiser les risques de fuite de la poudre vers cet extérieur.
Thus, we understand that three situations are possible:
  • either the valve 7 closes the body 1 while resting on the skirt 3 (case not shown), a dynamic seal being ensured at the level of the games remaining between the skirt 3 and the lower part 2 of the body 1, on the one hand, and between the mobile device 11 (closed position not shown) and the lower opening of the casing 10, on the other hand, due to the vacuum continuously established between the interior and the exterior of the device by means of suction, by the conduits 5a and 18, of an air current having circulated, from the air inlets 14 1 and 14 2 , at the location of the abovementioned sets in order to evacuate the powder which could have been there,
  • or the box 19 is in the process of docking on the opening of the casing 10 and on the skirt 3, the valve 7 being always in the low position, the air inlet 14 1 making it possible to avoid any outflow of powder from the device at the opening of the casing (first step mentioned above) thanks to the dynamic sealing phenomenon which has just been described,
  • or the box 19 is mounted on the skirt 3 (second and third steps above), the valve 7 being in the high position (see figure), and the aforementioned dynamic confinement is maintained, to avoid contamination by uncontrolled exit of powder outside of the device. Indeed, the ventilation assembly formed by the air intake circuits (14 1 and 14 2 ), the clearances existing between the skirt 3 and the lower part 2 of the body 1 (see the arrows in dotted lines which represent the passage of ventilation air at these games) and the outlet ducts (5a and 18) place the interior volume of the body 1 and of the box 19 in depression relative to the exterior in order to minimize the risks of powder leaks to this exterior.

Il va également de soi que l'admission de la poudre dans le tuyau 4 est avantageusement réalisée en discontinu c'est-à-dire uniquement pendant que la boíte 19 est en position de remplissage.It also goes without saying that the admission of the powder into the pipe 4 is advantageously made discontinuously, that is to say only while the box 19 is in the filling position.

Selon un mode particulier de mise en oeuvre de l'invention, on utilise, pour assurer le support de la boíte et son mouvement, un dispositif de type peson 22 formant des moyens de pesée qui permettent de façon connue, de mesurer le poids de ladite boíte 19 contenant des quantités variables de poudre.According to a particular embodiment of the invention, one uses, to ensure the support of the box and its movement, a device scale type 22 forming weighing means which allow known, to measure the weight of said box 19 containing quantities powder variables.

Ainsi, le détecteur de niveau 13 sert uniquement en cas de dérive de pesée du dispositif de pesage et assure le non-débordement de la boíte.Thus, the level detector 13 is used only in the event of weighing drift of the weighing device and ensures the non-overflow of the box.

On note que le dispositif de pesée de type peson 22 et le détecteur de niveau 13 constituent tous les deux des moyens de détection de la quantité de poudre contenue dans la boíte soit par mesure du poids, soit par détection du niveau atteint par la poudre.Note that the weighing device type 22 and the level 13 detector both constitute detection means of the quantity of powder contained in the box either by measurement of the weight, either by detecting the level reached by the powder.
