Description

VERROUILLAGE DE SECURITE D'UNE PORTE D'AUTOCLAVE SAFETY LOCK ON AN AUTOCLAVE DOOR
La présente invention concerne un dispositif de fermeture/verrouillage de la porte d'une enceinte et notamment d'une enceinte de traitement telle que par exemple un autoclave.The present invention relates to a device for closing / locking the door of an enclosure and in particular of a treatment enclosure such as for example an autoclave.
On sait que, notamment pour des raisons de sécurité, il est essentiel d'être en mesure d'une part de contrôler le 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 qui assurent respectivement une fonction de fermeture de la porte une fonction de verrouillage de celle-ci, et une fonction de signalisation du caractère achevé de cette fermeture.We know that, in particular for security reasons, it is essential to be able, on the one hand, to control the proper operating condition of the closure of an enclosure door inside which a process takes place. using high temperatures or pressures different from atmospheric pressure. It is of course possible to use individual devices which respectively provide a function for closing the door, a function for locking the latter, and a function for signaling the completion of this closure.
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 sur 1 * autre .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 on the other.
La présente invention a pour but de proposer un dispositif de fermeture qui assure à la fois une fonction de verrouillage de la porte pendant le temps d'utilisation de l'appareil, cet appareil étant notamment un autoclave, et le contrôle, notamment par une signalisation extérieure, de la fermeture correcte de celle-ci.The object of the present invention is to propose a closing device which provides both a door locking function during the time of use of the device, this device being in particular an autoclave, and control, in particular by signaling. exterior, of the correct closing thereof.
La présente invention a ainsi pour objet un dispositif de fermeture et de verrouillage de la porte d'une enceinte, du type comportant une broche montée à rotation axiale sur la porte et qui comporte à son extrémité libre au 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 de fermeture, caractérisé en ce qu'il comporte : des moyens capteurs qui sont aptes à être sollicités par la butée lorsque la broche se trouve en position de fermeture,The present invention thus relates to a device for closing and locking the door of an enclosure, of the type comprising a pin mounted at axial rotation on the door and which comprises at its free end at least one transverse stop which is able to cooperate with a cam-shaped surface which is integral with the frame of the enclosure so that a rotation of the spindle in one direction determined has the effect, by applying this stop on the cam, to apply the door in the closed position, characterized in that it comprises: sensor means which are capable of being acted upon by the stop when the spindle found in the closed position,
- des moyens de verrouillage comportant un verrou pourvu d'un logement apte à recevoir la butée et qui est mobile parallèlement à l'axe de la broche entre deux positions, à savoir une position de verrouillage dans laquelle le logement vient coiffer la butée et la bloquer en rotation et une position de déverrouillage dans laquelle il est dégagé de façon à autoriser la rotation de la broche, Préférentiellement les moyens de verrouillage comportent des moyens élastiques appliquant le verrou en position de verrouillage et des moyens de rappel à commande électrique amenant le verrou en position de déverrouillage, à 1 ' encontre des moyens élastiques, lorsqu'ils sont alimentés en courant électrique.- Locking means comprising a lock provided with a housing capable of receiving the stop and which is movable parallel to the axis of the spindle between two positions, namely a locking position in which the housing comes to cover the stop and the block in rotation and an unlocking position in which it is released so as to authorize the rotation of the spindle, Preferably the locking means comprise elastic means applying the lock in the locking position and electrically controlled return means bringing the lock in the unlocked position, against elastic means, when they are supplied with electric current.
Les moyens capteurs pourront avantageusement être reliés à des moyens électroniques commandant, dès qu'ils sont activés, 1 ' activation des moyens de verrouillage ou de déverrouillage. Dans un mode de mise en oeuvre de 1 ' invention le verrou sera solidaire d'un noyau monté mobile en translation dans un solénoïde. Ce verrou sera sollicité par un ressort de compression qui 1 ' amènera en position de verrouillage, lorsque le solénoïde n'est pas excité, le passage en position de déverrouillage du verrou étant alors obtenu par l'excitation du solénoïde.The sensor means can advantageously be connected to electronic means controlling, as soon as they are activated, the activation of the locking or unlocking means. In an embodiment of the invention, the lock will be secured to a core mounted movable 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 :Various embodiments of the present invention will be described below, by way of non-limiting example, with reference to the appended drawing in which:
La figure 1 est une vue en coupe brisée radiale et longitudinale d'un dispositif de fermeture/verrouillage d'une porte d'autoclave suivant l'invention, en position d'ouverture, suivant la ligne I-I de la figure 2. La figure 2 est une vue en coupe transversale du dispositif représenté sur la figure 1 suivant la ligne II- II de celle-ci.Figure 1 is a broken radial and longitudinal sectional view of a device for closing / locking an autoclave door according to the invention, in the open position, along line II of Figure 2. Figure 2 is a cross-sectional view of the device shown in Figure 1 along line II-II thereof.

La figure 4 est une vue en coupe transversale du dispositif représenté sur la figure 3 suivant la ligne IV- IV de celle-ci. La figure 5 est une vue en coupe transversale du dispositif représenté sur la figure 3 suivant la ligne V-V de celle-ci.Figure 4 is a cross-sectional view of the device shown in Figure 3 along line IV-IV thereof. 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 de sécurité empêchant 1 ' ouverture intempestive de la porte d'obturation. Un tel dispositif est installé sur la face frontale 1 de l'autoclave et est destiné à assurer la fermeture d'une porte 3 et plus précisément d'appliquer cette dernière dans le sens de la flèche F contre la face 1 de l'autoclave. A cet effet la porte 3 est munie d'une broche 5 perpendiculaire qui est montée à rotation autour de son axe longitudinal yy' et qui est fixe en translation par rapport à 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.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, that is to say devices requiring the implementation of security means preventing one inadvertent opening of the shutter door. 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. To this end, the door 3 is provided with a perpendicular pin 5 which is mounted for rotation about its longitudinal axis yy 'and which is fixed in translation relative to the door 3. The pin 5 is provided, at its free end, 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 1 et 2, en position horizontale. La face interne de la paroi 1 reçoit une platine 6 qui, ainsi que représenté sur les figures 1 et 2, présente deux profils 9 et 9 ' en forme de came. Ces profils sont tels que, lorsque partant de la position représentée sur les figures 1 et 2, on imprime à la broche 5 un mouvement de rotation dans le sens des aiguilles d'une montre (flèche C sur les figures 1 et 3), on amène, dans un premier temps, les axes 7 en contact avec la 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 yy ' de celle-ci. Lorsque, ainsi que représenté sur les figures 3 et 4, on a fait tourner la broche 5 d'un quart de tour, les axes 7 se trouvent alors en position verticale et sont ainsi en appui sur la face interne de la platine 6, si bien que dans ces conditions, le déplacement horizontal F de la broche 5 est terminé. Ce mouvement de déplacement permet d'appliquer par exemple un joint dont serait pourvue la porte 3 contre une zone complémentaire de 1 ' étuve permettant d'assurer 1 ' étanchéité. On peut bien entendu prévoir des moyens de butée permettant de bloquer la rotation de la broche 5 lorsque celle-ci a tourné d'un quart de tour et que les axes 7 se trouvent en position verticale ou position de fermeture de la porte 3. La face interne de la platine 6 reçoit un microinterrupteur 11 qui est pourvu d'un palpeur 13 disposé en extrémité d'un bras de levier 15. Lorsque les axes 7 se trouvent en position verticale, ainsi que représenté 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. Le micro-interrupteur 11 est relié à un circuit de commutation 17 qui, d'une part, assure l'alimentation électrique d'une lampe de signalisation 19 et la mise en place d'un verrou 25 destiné à empêcher l'utilisateur de faire tourner la broche 5 pour ouvrir la porte 3.In the open position of the door 3, these axes 7 are, as shown in Figures 1 and 2, in a horizontal position. The internal face of the wall 1 receives a plate 6 which, as shown in Figures 1 and 2, has two profiles 9 and 9 'in the form of a cam. These profiles are such that, starting from the position shown in FIGS. 1 and 2, the spindle 5 is rotated in a clockwise direction (arrow C in FIGS. 1 and 3), brings, 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 yy' thereof. When, as shown in FIGS. 3 and 4, the spindle 5 has been rotated by a quarter turn, the axes 7 are then in a vertical position and are thus in abutment on the internal face of the plate 6, if although under these conditions, the horizontal movement F of the spindle 5 is finished. This movement of displacement makes it possible to apply, for example, a seal which would be provided with the door 3 against a zone complementary to the oven, making it possible to ensure sealing. It is of course possible to provide abutment means making it possible to block the rotation of the spindle 5 when the latter has turned a quarter of a turn and the axes 7 are in the vertical position or the closed position of the door 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 the axes 7 are in the vertical position, as shown in FIGS. 3 and 4, l '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. The microswitch 11 is connected to a switching circuit 17 which, 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 making turn pin 5 to open door 3.
Les moyens de verrouillage sont constitués d'un solénoïde 21 qui comporte en son centre un noyau mobile 23 dont l'extrémité est reliée au verrou 25. Ce dernier est creusé d'un orifice circulaire central 26 destiné à admettre 1 ' extrémité de la broche 5 et de deux cavités verticales 27 de forme complémentaire de celle des axes 7. Un ressort de compression 28 est disposé entre le solénoïde 21 et le verrou 25. Dans ces conditions, lorsque le solénoïde 21 n'est pas alimenté en courant, le ressort 28 repousse le verrou 25 qui 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 la flèche C) si bien que la porte 3 se trouve ainsi verrouillée.The locking means consist of a solenoid 21 which has at its center a movable core 23, the end of which is connected to the lock 25. The latter is hollowed out with a central circular orifice 26 intended to admit the end of the spindle 5 and of two vertical cavities 27 of shape complementary to that of the axes 7. A compression spring 28 is disposed between the solenoid 21 and the latch 25. Under these conditions, when the solenoid 21 is not not supplied with current, the spring 28 pushes the lock 25 which thus covers 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 ( anticlockwise, 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 rappelé dans le solénoïde, ce qui a pour effet de faire reculer le verrou 25 dans le sens de la flèche F, ce qui assure le 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 25 move back in the direction of the arrow F, which ensures the unlocking of the door 3.
Le présent mode de mise en oeuvre de verrouillage est particulièrement 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 ne se trouve pas libérée mais au contraire passe en mode verrouillage. La présente invention est également intéressante en ce 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 locking implementation mode 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. from the solenoid the door 3 is not released but on the contrary goes into locking mode. The present invention is also advantageous in 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.
