Abstract
Description
La présente invention concerne un dispositif fermeture/verrouillage de la porte d'une enceinte notamment d'une enceinte de traitement telle que par exemple un autoclave. On sait que, notamment pour des raisons de sécurité, est essentiel d'être en mesure d'une part de contrôler bon état de fonctionnement de la fermeture d'une porte d'enceinte à l'intérieur de laquelle se déroule un processus mettant en oeuvre des températures élevées ou des pressions différentes de la pression atmosphérique. On peut bien entendu faire appel à des dispositifs individuels assurent respectivement une fonction de fermeture de porte une fonction de verrouillage de celle-ci, et fonction signalisation du caractère achevé de cette fermeture. De tels moyens séparés se révèlent à l'usage onéreux notamment pour la raison que chacun d'eux est parfois conduit à utiliser des éléments qui sont mis en oeuvre l'autre. La presente invention a pour but de proposer dispositif de fermeture qui assure à la fois une fonction verrouillage de la porte pendant le temps d'utilisation l'appareil, cet appareil étant notamment un autoclave, et contrôle, notamment par une signalisation extérieure, de fermeture correcte de celle-ci. présente invention a ainsi pour objet dispositif fermeture et de verrouillage de la porte d' enceinte, type comportant une broche montée à rotation axiale sur porte et qui comporte à son extrémité libre moins une butée transversale qui est apte à coopérer avec une surface en forme de came qui est solidaire du bâti de l'enceinte de façon qu'une rotation de la broche dans un sens déterminé ait pour effet, par l'application de cette butée sur la came, d'appliquer la porte en position fermeture, caractérisé en ce qu'il comporte - des moyens capteurs qui sont aptes à être sollicites par la butée lorsque la broche se trouve en position fermeture, - moyens de verrouillage comportant un verrou pourvu 'un logement apte à recevoir la butée et qui mobile parallèlement à l'axe de la broche entre deux positions, à savoir une position de verrouillage dans laquelle logement vient coiffer la butée et la bloquer en rotation une position de déverrouillage dans laquelle il est dégage de façon à autoriser la rotation de la broche, Preferentiellement les moyens de verrouillage comportent des moyens élastiques appliquant le verrou en position verrouillage et des moyens de rappel à commande électrique amenant le verrou en position de déverrouillage, à l'encontre des moyens élastiques, lorsqu'ils sont alimentes en courant électrique. The present invention relates to a device for closing / locking the door of an enclosure, in particular a processing enclosure such as, for example, an autoclave. We know that, in particular for security reasons, it is essential to be able, on the one hand, to control the proper functioning of the closing of an enclosure door inside which takes place a process putting in operates high temperatures or pressures different from atmospheric pressure. It is of course possible to use individual devices respectively providing a door closing function, a locking function for the latter, and signaling function of the completed nature of this closing. Such separate means prove to be expensive use in particular for the reason that each of them is sometimes led to use elements which are used the other. The object of the present invention is to propose a closing device which ensures both a locking function of the door during the time of use of the device, this device being in particular an autoclave, and control, in particular by external signaling, of closing. correct of it. object of the present invention is thus a device for closing and locking the enclosure door, of the type comprising a spindle mounted in axial rotation on the door and which comprises at its free end at least one transverse stop which is capable of cooperating with a surface in the form of cam which is integral with the frame of the enclosure so that a rotation of the spindle in a determined direction has the effect, by the application of this stop on the cam, of applying the door in the closed position, characterized in that that it comprises - sensor means which are capable of being acted upon by the stop when the spindle is in the closed position, - locking means comprising a lock provided with a housing capable of receiving the stop and which moves parallel to the axis of the spindle between two positions, namely a locking position in which housing comes to cover the stop and block it in rotation an unlocking position e in which it is released so as to allow the rotation of the spindle, Preferably the locking means comprise elastic means applying the lock in the locked position and return means with electric control bringing the lock in the unlocked position, when against elastic means, when supplied with electric current.
moyens capteurs pourront avantageusement être reliés a moyens électroniques commandant, dès qu' sont actives, l'activation des moyens de verrouillage ou déverrouillage. Dans un mode de mise en oeuvre de l'invention le verrou sera solidaire d'un noyau monté mobile en translation dans un solénoïde. Ce verrou sera sollicité par un ressort compression qui l'amènera en position de verrouillage, lorsque le solénoïde n'est pas excité, le passage en position de déverrouillage du verrou étant alors obtenu par 'excitation du solénoïde. sensor means may advantageously be connected to electronic means controlling, as soon as they are active, the activation of the locking or unlocking means. In one embodiment of the invention, the lock will be secured to a core mounted to move in translation in a solenoid. This lock will be biased by a compression spring which will bring it into the locking position, when the solenoid is not excited, the passage into the unlocking position of the lock then being obtained by 'excitation of the solenoid.
On décrira ci-après, à titre d'exemple non limitatif, diverses formes d'exécution de la présente invention, en référence au dessin annexé sur lequel La figure 1 est une vue en coupe brisee radiale et longitudinale d'un dispositif de fermeture/verrouillage 'une porte d'autoclave suivant l'invention, en position ouverture, suivant la ligne I-I de la figure 2. Various embodiments of the present invention will be described below, by way of nonlimiting example, with reference to the appended drawing in which FIG. 1 is a view in radial and longitudinal broken section of a closure device / locking an autoclave door according to the invention, in the open position, along line II of FIG. 2.

Figure 3 is a radial and longitudinal sectional broken view of the closure / locking device shown in Figures 1 and 2 in the closed position.
La figure 4 est une vue en coupe transversale du dispositif représenté sur la figure 3 suivant ligne IV-IV celle-ci. Figure 4 is a cross-sectional view of the device shown in Figure 3 along line IV-IV thereof.
La figure 5 est une vue en coupe transversale du dispositif représenté sur la figure 3 suivant ligne V-V celle-ci. Figure 5 is a cross-sectional view of the device shown in Figure 3 along line V-V thereof.
On a représenté sur les figures 1 à 5 un mode de mise en oeuvre d'un dispositif de fermeture/verrouillage d'un autoclave, le présent dispositif pouvant bien entendu être mis en oeuvre sur d'autres appareils de même type, c'est-à- dire des appareils nécessitant la mise en oeuvre de moyens sécurité empêchant l'ouverture intempestive la porte 'obturation. There is shown in Figures 1 to 5 an embodiment of a device for closing / locking an autoclave, the present device can of course be implemented on other devices of the same type, it is ie devices requiring the implementation of security means preventing inadvertent opening of the door 'shutter.
Un tel dispositif est installé sur la face frontale 1 l'autoclave et est destiné à assurer la fermeture d'une porte 3 et plus précisément d'appliquer cette dernière dans sens de la flèche F contre la face 1 de l'autoclave. A effet la porte 3 est munie d'une broche 5 perpendiculaire qui est montée à rotation autour son axe longitudinal yy' et qui est fixe en translation rapport la porte 3. La broche 5 est pourvue, à son extrémité libre, de deux axes radiaux 7 qui dépassent de sa surface extérieure et qui constituent le pêne des moyens de verrouillage. Such a device is installed on the front face 1 of the autoclave and is intended to ensure the closing of a door 3 and more precisely to apply the latter in the direction of arrow F against the face 1 of the autoclave. Indeed, the door 3 is provided with a perpendicular spindle 5 which is mounted for rotation about its longitudinal axis yy 'and which is fixed in translation relative to the door 3. The spindle 5 is provided, at its free end, with two radial axes 7 which protrude from its outer surface and which constitute the bolt of the locking means.
En position d'ouverture de la porte 3, ces axes 7 se trouvent, ainsi que représenté sur les figures et 2, en position horizontale. La face interne de la paroi 1 reçoit platine 6 qui, ainsi que représenté sur les figures 1 et présente deux profils 9 et 9' en forme came. Ces profils sont tels que, lorsque partant de position représentée sur les figures 1 et 2, on imprime a broche 5 mouvement de rotation dans le sens des aiguilles d'une montre (flèche C sur les figures 1 et 3), on amene, dans un premier temps, les axes 7 en contact avec base des profils 9 et 9' en forme de came et, si l'on continue la rotation de la broche 5, cette rotation, en raison du contact des axes 7 sur les profils 9 et 9', imprime un déplacement axial de la broche 5 suivant l'axe ' de celle- ci. Lorsque, ainsi que représenté sur les figures et 4, a fait tourner la broche 5 d'un quart de tour, axes 7 trouvent alors en position verticale et sont ainsi en appui sur la face interne de la platine 6, si bien que dans conditions, le déplacement horizontal F de broche 5 terminé. Ce mouvement de déplacement permet 'appliquer exemple un joint dont serait pourvue la porte contre une zone complémentaire de l'étuve permettant assurer 'étanchéité. On peut bien entendu prévoir des moyens butée permettant de bloquer la rotation de la broche 5 lorsque celle-ci a tourné d'un quart de tour et que axes 7 se trouvent en position verticale ou position fermeture de porte 3. In the open position of the door 3, these axes 7 are, as shown in the figures and 2, in a horizontal position. The internal face of the wall 1 receives plate 6 which, as shown in Figures 1 and has two profiles 9 and 9 'in cam shape. These profiles are such that, starting from the position shown in FIGS. 1 and 2, a rotational movement in the clockwise direction is printed with spindle (arrow C in FIGS. 1 and 3), in firstly, the axes 7 in contact with the base of the profiles 9 and 9 ′ in the form of a cam and, if the rotation of the spindle 5 is continued, this rotation, due to the contact of the axes 7 on the profiles 9 and 9 ', prints an axial displacement of the spindle 5 along the axis' thereof. When, as shown in Figures and 4, has rotated the spindle 5 a quarter turn, axes 7 are then in a vertical position and are thus supported on the internal face of the plate 6, so that under conditions , the horizontal movement F of spindle 5 finished. This movement of movement makes it possible to apply, for example, a seal which would be provided with the door against a complementary zone of the oven allowing to ensure sealing. It is of course possible to provide stop means making it possible to block the rotation of the spindle 5 when the latter has rotated by a quarter of a turn and that the axes 7 are in the vertical position or the door closing position 3.
La face interne de la platine 6 reçoit un micro- interrupteur 11 qui est pourvu d'un palpeur 13 disposé en extrémité d'un bras de levier 15. Lorsque axes 7 se trouvent en position verticale, ainsi que representé sur les figures 3 et 4, l' axe supérieur 7 vient en contact avec le palpeur 13 du micro-interrupteur 11 et repousse celui-ci ouvrant ainsi (ou fermant) un circuit électrique. micro- interrupteur 11 est relié à un circuit de commutation 17 d'une part, assure l'alimentation électrique d'une lampe de signalisation 19 et la mise en place 'un verrou 25 destiné à empêcher l'utilisateur de faire tourner broche pour ouvrir la porte 3. The internal face of the plate 6 receives a microswitch 11 which is provided with a feeler 13 disposed at the end of a lever arm 15. When axes 7 are in the vertical position, as shown in FIGS. 3 and 4 , the upper axis 7 comes into contact with the probe 13 of the microswitch 11 and pushes the latter thus opening (or closing) an electrical circuit. microswitch 11 is connected to a switching circuit 17 on the one hand, ensures the electrical supply of a signaling lamp 19 and the installation of a lock 25 intended to prevent the user from turning the spindle to open door 3.
Les moyens de verrouillage sont constitues d'un solénoïde 21 qui comporte en son centre un noyau mobile 23 dont l'extrémité est reliée au verrou 25. dernier est creusé 'un orifice circulaire central 26 destiné à admettre l'extrémité de la broche 5 et de deux cavités verticales de forme complémentaire de celle des axes 7. Un ressort compression 28 est disposé entre le solénoïde 21 et verrou Dans ces conditions, lorsque le solénoïde 21 n'est alimente en courant, le ressort 28 repousse le verrou 25 vient ainsi coiffer l'extrémité de l'axe 5 et les deux axes 7. Dans cette position l'utilisateur ne peut plus faire pivoter la broche 5 dans le sens du déverrouillage (sens inverse des aiguilles d'une montre, soit le sens opposé à flèche C) si bien que la porte 3 se trouve ainsi verrouillée. The locking means consist of a solenoid 21 which has in its center a movable core 23, the end of which is connected to the lock 25. the latter is hollowed out 'a central circular orifice 26 intended to admit the end of the spindle 5 and of two vertical cavities of shape complementary to that of the axes 7. A compression spring 28 is disposed between the solenoid 21 and latch Under these conditions, when the solenoid 21 is not supplied with current, the spring 28 pushes the latch 25 thus comes to cap the end of the axis 5 and the two axes 7. In this position the user can no longer rotate the spindle 5 in the unlocking direction (anti-clockwise direction, ie the direction opposite to arrow C ) so that door 3 is thus locked.
Lorsque le solénoïde 21 est alimenté en courant électrique le noyau 23 disposé dans celui-ci est rappele dans le solénoïde, ce qui a pour effet de faire reculer verrou dans le sens de la flèche F, ce qui assure déverrouillage de la porte 3. When the solenoid 21 is supplied with electric current, the core 23 disposed in it is returned to the solenoid, which has the effect of making the lock move back in the direction of the arrow F, which ensures unlocking of the door 3.
Le présent mode de mise en oeuvre de verrouillage particulierement intéressant en ce qu'il permet d'assurer une sécurité maximale dans la mesure où, en cas d'interruption intempestive du courant électrique, et donc d'interruption de l'alimentation en courant du solénoïde la porte 3 se trouve pas libérée mais au contraire passe mode verrouillage. This locking mode of implementation is particularly advantageous in that it ensures maximum security insofar as, in the event of untimely interruption of the electric current, and therefore interruption of the current supply to the door 3 solenoid is not released but on the contrary goes into locking mode.
La présente invention est également intéressante en sens qu'elle permet à l'aide de moyens simples d'assurer trois fonctions à savoir d'une part la fermeture de la porte, la signalisation de cette fermeture et le verrouillage de la fermeture.The present invention is also advantageous in the sense that it makes it possible, using simple means, to perform three functions, namely, on the one hand, closing the door, signaling this closure and locking the closure.
