Description
Dispositif d'arrêt d'urgence avec ensembles de commutation à assemblage sécurisé Emergency stop device with secure assembly switching assemblies
La présente invention se rapporte à un dispositif de commutation de type arrêt d'urgence. The present invention relates to a switching device of the emergency stop type.
En règle générale, un dispositif de commutation de type arrêt d'urgence comporte un ensemble de commande portant un organe d'actionnement et au moins un ensemble de commutation appelé également bloc de contacts destiné à être monté à l'arrière de l'ensemble de commande. L'ensemble de commutation comporte un pont mobile supportant des contacts mobiles actionnés par l'organe d'actionnement par rapport à des contacts fixes d'une position de fermeture vers une position d'ouverture pour ouvrir un circuit électrique en cas d'urgence. Dans un dispositif d'arrêt d'urgence, les contacts principaux sont donc de type normalement fermé. As a general rule, an emergency stop type switching device comprises a control assembly carrying an actuating member and at least one switching assembly also called a contact block intended to be mounted at the rear of the set of switches. ordered. The switching assembly comprises a movable bridge supporting movable contacts actuated by the actuating member with respect to fixed contacts from a closed position to an open position to open an electrical circuit in an emergency. In an emergency stop device, the main contacts are therefore of normally closed type.
Lors du montage du dispositif, l'ensemble de commande et l'ensemble de commutation sont montés mécaniquement de part et d'autre d'une paroi. L'ensemble de commutation est donc invisible à l'utilisateur. Il est donc impossible pour l'utilisateur de savoir en permanence si l'ensemble de commande est bien monté sur l'ensemble de commutation. Or un décrochage de l'un des ensembles par rapport à l'autre ne permet plus au dispositif de fonctionner correctement. Etant donné qu'un dispositif d'arrêt d'urgence est destiné à exercer une fonction de sécurité, il est nécessaire que ce dispositif fonctionne correctement. Pour cela, Il faut donc s'assurer que l'ensemble de commutation est bien accroché à l'ensemble de commande lorsque le dispositif d'arrêt d'urgence est amené à fonctionner. When mounting the device, the control assembly and the switching assembly are mounted mechanically on either side of a wall. The switching assembly is therefore invisible to the user. It is therefore impossible for the user to know continuously whether the control assembly is properly mounted on the switching assembly. But a stall of one of the sets relative to the other no longer allows the device to work properly. Since an emergency stop device is intended to exercise a safety function, it is necessary that this device functions properly. For this, it is necessary to ensure that the switching assembly is hooked to the control assembly when the emergency stop device is operated.
Il est notamment connu des brevets US 6,198,058 et DE4101493 des dispositifs permettant de surveiller l'accrochage de l'ensemble de commande sur l'ensemble de commutation. Dans ces deux brevets, un jeu de contacts normalement fermés et un jeu de contacts normalement ouverts sont mis en série sur le circuit électrique à commander. Tant que l'ensemble de commutation est déconnecté mécaniquement de l'ensemble de commande, les contacts normalement ouverts restent ouverts et lors du montage de l'ensemble de commutation sur l'ensemble de commande, ces contacts normalement ouverts se ferment. En fonctionnement normal, lors d'une pression sur l'organe d'actionnement, les contacts normalement fermés s'ouvrent.
Cependant, ces solutions de l'état de la technique ont pour seul but de surveiller l'accrochage d'un seul ensemble de commutation. Or il est courant qu'un dispositif d'arrêt d'urgence puisse comporter plusieurs ensembles de commutation adjacents, c'est-à-dire un ensemble de commande principal et un ou plusieurs ensembles de commutation de type auxiliaires qui sont accrochés à l'arrière de l'ensemble de commande. Pour s'assurer qu'ils sont tous bien accrochés à l'ensemble de commande, il faudrait donc leur attribuer à chacun un mécanisme spécifique du type de celui décrit dans les brevets de l'art antérieur. Mais lorsque les ensembles de commutation auxiliaires sont destinés à réaliser des fonctions simples, par exemple de type signalisation ou sont connectés en redondance de l'ensemble de commutation principal, l'ajout d'un mécanisme spécifique pour sécuriser leur accrochage semble inadapté car complexe et trop coûteux. US Pat. No. 6,198,058 and DE4101493 disclose devices for monitoring the attachment of the control assembly to the switching assembly. In these two patents, a set of normally closed contacts and a set of normally open contacts are placed in series on the electrical circuit to be controlled. As long as the switching assembly is mechanically disconnected from the control assembly, the normally open contacts remain open and when mounting the switching assembly on the control assembly these normally open contacts close. In normal operation, when pressing on the actuator, the normally closed contacts open. However, these solutions of the state of the art are only intended to monitor the attachment of a single switching assembly. However, it is common for an emergency stop device to have a plurality of adjacent switch assemblies, i.e., a master control assembly and one or more auxiliary type switch assemblies that are attached to the master switch assembly. rear of the command set. To ensure that they are all firmly attached to the control unit, it should therefore be assigned to each a specific mechanism of the type described in the patents of the prior art. But when the auxiliary switching assemblies are intended to perform simple functions, for example signaling type or are redundantly connected to the main switching assembly, the addition of a specific mechanism to secure their attachment seems inappropriate because complex and too expensive.
Le but de l'invention est de proposer un dispositif de commutation de type arrêt d'urgence dans lequel il est possible de sécuriser l'accrochage de ses ensembles de commutation de manière fiable, simple et peu coûteuse. The object of the invention is to provide an emergency stop type switching device in which it is possible to secure the attachment of its switching assemblies reliably, simply and inexpensively.
Ce but est atteint par un dispositif de commutation de type arrêt d'urgence comportant un ensemble de commande doté d'un organe d'actionnement pouvant prendre une position de repos et une position d'actionnement, un premier ensemble de commutation et un deuxième ensemble de commutation destinés à être assemblés mécaniquement suivant un axe de fixation par leur face avant sur l'ensemble de commande, le deuxième ensemble de commutation étant positionné de manière adjacente au premier ensemble de commutation, le premier ensemble de commutation comportant : This object is achieved by an emergency stop type switching device comprising a control unit provided with an actuating member that can assume a rest position and an actuating position, a first switching assembly and a second set. switching devices intended to be mechanically assembled along a fixing axis by their front face on the control assembly, the second switching assembly being positioned adjacent to the first switching assembly, the first switching assembly comprising:
- un commutateur d'actionnement de type normalement fermé destiné à commander un circuit électrique selon la position de l'organe d'actionnement, a normally closed type operating switch intended to control an electrical circuit according to the position of the actuating member,
- un dispositif mécanique pour ouvrir le circuit électrique lorsque l'ensemble de commande est décroché mécaniquement du premier ensemble de commutation, a mechanical device for opening the electrical circuit when the control assembly is mechanically unhooked from the first switching assembly,
caractérisé en ce que le premier ensemble de commutation comporte : characterized in that the first switching assembly comprises:
- des moyens mécaniques aptes à agir sur le deuxième ensemble de commutation pour assurer l'accrochage mécanique du deuxième ensemble de commutation sur l'ensemble de commande lorsque le
premier ensemble de commutation est accroché mécaniquement sur l'ensemble de commande. mechanical means able to act on the second switching assembly to ensure the mechanical attachment of the second switching assembly on the control assembly when the first switching assembly is mechanically hooked to the control assembly.
Selon une particularité, le premier ensemble de commutation comporte un boîtier et les moyens mécaniques comportent une partie saillante réalisée sur le boîtier et coopérant avec une face arrière du deuxième ensemble de commutation lorsque le premier ensemble de commutation est accroché mécaniquement sur l'ensemble de commande. According to one particular feature, the first switching assembly comprises a housing and the mechanical means comprise a projecting part made on the housing and cooperating with a rear face of the second switching assembly when the first switching assembly is mechanically hooked onto the control assembly. .
Selon une autre particularité, la partie saillante est constituée d'une ailette réalisée perpendiculairement à l'axe de fixation. Selon une autre particularité, le dispositif comporte une seconde ailette réalisée symétriquement à la première ailette et destinée à coopérer avec une face arrière d'un troisième ensemble de commutation pour s'assurer de son accrochage lorsque le premier ensemble de commutation est accroché mécaniquement sur l'ensemble de commande, ce troisième ensemble de commutation étant positionné de manière adjacente au premier ensemble de commutation. According to another feature, the projecting portion consists of a fin made perpendicular to the axis of attachment. According to another feature, the device comprises a second fin made symmetrically to the first fin and intended to cooperate with a rear face of a third switching assembly to ensure that it latches when the first switch assembly is mechanically hooked on the control assembly, said third switching assembly being positioned adjacent the first switching assembly.
D'autres caractéristiques et avantages vont apparaître dans la description détaillée qui suit en se référant à un mode de réalisation donné à titre d'exemple et représenté par les dessins annexés sur lesquels : Other features and advantages will appear in the detailed description which follows with reference to an embodiment given by way of example and represented by the appended drawings in which:

De manière connue, un dispositif de commutation de type arrêt d'urgence, appelé également interrupteur coup de poing, comporte au moins deux ensembles 1 , 2
distincts formés d'un ensemble de commande 1 et d'un ou plusieurs ensembles de commutation 2a, 2b, 2c. In known manner, an emergency stop-type switching device, also called a punch switch, comprises at least two sets 1, 2 separate formed of a control unit 1 and one or more switching assemblies 2a, 2b, 2c.
En référence à la figure 1 , l'ensemble de commande 1 comporte un organe d'actionnement 10 destiné à être enfoncé en cas d'urgence par l'opérateur suivant un axe de commande (X) pour ouvrir un circuit électrique. L'organe d'actionnement 10 peut ainsi prendre une position de repos, dans laquelle il n'est pas enfoncé, laissant le circuit électrique fermé et une position d'actionnement dans laquelle il est enfoncé pour ouvrir le circuit électrique. Referring to Figure 1, the control assembly 1 comprises an actuating member 10 to be depressed in an emergency by the operator along a control axis (X) to open an electrical circuit. The actuating member 10 can thus take a rest position, in which it is not depressed, leaving the electric circuit closed and an actuating position in which it is depressed to open the electric circuit.
Les ensembles de commutation 2a, 2b, 2c sont destinés à être accrochés par leur face avant f1 , f10, f20 suivant un axe de fixation confondu avec l'axe de commande (X) à l'arrière de l'ensemble de commande 1 . The switching assemblies 2a, 2b, 2c are intended to be hooked by their front face f1, f10, f20 along an axis of attachment coinciding with the control axis (X) at the rear of the control unit 1.
Typiquement le dispositif de commutation de type arrêt d'urgence comporte un ensemble de commutation principal 2a destiné à la commande du circuit électrique et par exemple un ou deux ensembles de commutation auxiliaires 2b, 2c adjacents à l'ensemble de commutation principal 2a et destinés à assurer par exemple des fonctions de signalisation. L'un des deux ensembles de commutation auxiliaires comporte par exemple un jeu de contacts électriques normalement fermés (appelé NC pour "Normally Closed"), appelé également contacts à ouverture, tandis que l'autre ensemble de commutation auxiliaire comporte un jeu de contacts électriques normalement ouverts (appelé NO pour "Normally Opened"), appelé également contacts à fermeture. Ces ensembles de commutation auxiliaires sont couramment utilisés dans les dispositifs de commutation déjà présents sur le marché. Typically the emergency stop type switching device comprises a main switching assembly 2a for controlling the electric circuit and for example one or two auxiliary switching assemblies 2b, 2c adjacent to the main switching assembly 2a and intended for for example, to provide signaling functions. One of the two auxiliary switching assemblies comprises for example a set of normally closed electrical contacts (called NC for "Normally Closed"), also called open contacts, while the other auxiliary switching assembly comprises a set of electrical contacts. normally open (called NO for "Normally Opened"), also called closed contacts. These auxiliary switching assemblies are commonly used in switching devices already on the market.
Le principe de l'invention est de pouvoir sécuriser l'accrochage d'au moins un ensemble de commutation à l'aide d'un autre ensemble de commutation dont l'accrochage est surveillé grâce à un dispositif spécifique. Autrement dit, un premier ensemble de commutation qui est accroché à l'arrière de l'ensemble de commande comporte un dispositif permettant de surveiller qu'il est bien accroché à l'ensemble de commande et des moyens mécaniques aptes à agir sur un deuxième ensemble de commutation adjacent pour assurer l'accrochage mécanique de cet ensemble de commutation sur l'ensemble de commande. The principle of the invention is to be able to secure the attachment of at least one switching assembly by means of another switching assembly whose attachment is monitored by a specific device. In other words, a first switching assembly that is hooked to the rear of the control assembly comprises a device for monitoring that it is hooked to the control assembly and mechanical means able to act on a second set adjacent switch to ensure mechanical attachment of this switching assembly on the control assembly.
Selon l'invention, l'ensemble de commutation principal 2a permet donc de sécuriser l'assemblage d'un ou deux ensembles de commutation auxiliaires 2b, 2c sur l'ensemble de commande 1 . Pour cela, chaque ensemble de commutation auxiliaire
2b, 2c doit être positionné de manière adjacente à l'ensemble de commutation principal 2a. Si le dispositif comporte deux ensembles de commutation auxiliaires 2b, 2c, ces ensembles doivent être positionnés de part et d'autre de l'ensemble de commutation principal 2a (figures 1 A et 1 B). According to the invention, the main switching assembly 2a thus makes it possible to secure the assembly of one or two auxiliary switching assemblies 2b, 2c on the control unit 1. For this, each auxiliary switching assembly 2b, 2c must be positioned adjacent to the main switching assembly 2a. If the device comprises two auxiliary switching assemblies 2b, 2c, these sets must be positioned on either side of the main switching assembly 2a (FIGS. 1A and 1B).
L'ensemble de commutation principal 2a est par exemple du type représenté sur les figures 2A à 6. The main switching assembly 2a is for example of the type shown in FIGS. 2A to 6.
Il comporte notamment, comme dans les brevets US 6,198,058 et DE4101493 de l'art antérieur, un dispositif mécanique qui permet d'ouvrir le circuit électrique commandé lorsque l'ensemble de commande est décroché mécaniquement, permettant ainsi de s'assurer que l'ensemble de commutation principal 2a est bien accroché lorsque le dispositif d'arrêt d'urgence doit fonctionner. D'autres solutions sont également présentées dans les demandes déposées par la demanderesse sous les n °PCT/EP2009/062736 et FR0956479. Les figures 2A à 6 représentent donc une variante de réalisation aux solutions décrites dans ces brevets antérieurs. It comprises, in particular, as in US Pat.

This assembly 2a comprises a housing 20 (FIG. 6), for example made of plastic, having hooking means 21a, 21b to the control assembly 1. According to the invention, the housing 20 contains an actuating switch for controlling the electrical circuit according to the position of the actuating member 10. The housing 20 also contains a detection switch for monitoring that the switching assembly main 2a is hooked on the control assembly 1 by keeping the electrical circuit open as the command set is mechanically disconnected from the main switching assembly 2a. The operation switch has a set of normally closed operating contacts and the detection switch has a set of normally open sense contacts. The operation switch and the detection switch are connected in series to the electrical circuit to be controlled.
Plus précisément, le commutateur d'actionnement comporte un support mobile d'actionnement 3 et un ressort principal 4 positionné entre le support mobile d'actionnement 3 et le boîtier 20. Le support mobile d'actionnement 3 est constitué de deux demi-plaques conductrices 30, 31 de l'électricité assemblées sur une pièce centrale 32 qui est en matériau isolant, par exemple en plastique, cette pièce centrale
32 étant montée sur le ressort principal 4. Chaque demi-plaque 30, 31 porte à son extrémité un contact d'actionnement 300, 310 mobile apte à coopérer avec un contact d'actionnement 200, 210 fixe correspondant pour commander le circuit électrique. Le support mobile d'actionnement 3 est initialement dans une position de fermeture des contacts et est apte à se déplacer vers une position d'ouverture lorsque l'organe d'actionnement 10 est enfoncé dans sa position d'actionnement. More specifically, the actuating switch comprises a movable actuating support 3 and a main spring 4 positioned between the movable actuating support 3 and the housing 20. The movable actuating support 3 consists of two conductive half-plates. 30, 31 assembled on a central piece 32 which is made of insulating material, for example plastic, this central piece 32 being mounted on the main spring 4. Each half-plate 30, 31 carries at its end an actuating contact 300, 310 movable adapted to cooperate with a corresponding fixed actuating contact 200, 210 for controlling the electrical circuit. The movable actuating support 3 is initially in a closed position of the contacts and is able to move to an open position when the actuating member 10 is depressed in its actuating position.
Le commutateur de détection comporte pour sa part un support mobile de détection 5, un ressort d'ouverture 6 et un ressort 7 de pression de contacts. Le support mobile de détection 5 comporte une pièce conductrice 50 de l'électricité présentant une section transversale en forme de chapeau portant à chaque extrémité un contact de détection 501 , 51 1 mobile. Les contacts de détection 301 , 31 1 correspondants aux deux contacts de détection 501 , 51 1 mobiles sont dits contacts de détection "fixes" et sont réalisés sur le support mobile d'actionnement 3, de telle sorte qu'ils sont solidaires en mouvement du support mobile d'actionnement 3. Ces contacts 301 , 31 1 sont en effet fixes sur le support mobile d'actionnement lorsque ce dernier est en position de fermeture ou en position d'ouverture mais se déplacent avec le support mobile d'actionnement 3 lorsque celui-ci change de position. Le jeu de contacts de détection est placé entre les deux ensembles formés chacun d'un contact fixe d'actionnement et d'un contact mobile d'actionnement. The detection switch comprises, for its part, a mobile detection support 5, an opening spring 6 and a contact pressure spring 7. The mobile detection medium 5 comprises a conductive piece 50 of electricity having a hat-shaped cross-section carrying at each end a movable detection contact 501, 51 1. The detection contacts 301, 31 1 corresponding to the two movable detection contacts 501, 51 1 are said "fixed" detection contacts and are made on the mobile actuating support 3, so that they are integral in movement with each other. mobile movable support 3. These contacts 301, 31 1 are in fact fixed on the mobile operating support when the latter is in the closed position or in the open position but move with the mobile actuating support 3 when this one changes position. The set of detection contacts is placed between the two sets each formed of a fixed actuating contact and a movable actuating contact.
Le support mobile d'actionnement 3 et le support mobile de détection 5 sont déplaçables en translation suivant l'axe de commande (X). Le support mobile d'actionnement 3 est initialement dans une position de fermeture dans laquelle ses contacts d'actionnement sont fermés et est apte à se déplacer vers une position d'ouverture dans laquelle ses contacts d'actionnement sont ouverts. Le support mobile de détection 5 est initialement dans une position d'ouverture dans laquelle ses contacts de détection sont ouverts et est apte à se déplacer vers une position de fermeture dans laquelle ses contacts de détection sont fermés. Lorsque le support mobile de détection 5 est en position de fermeture, la pièce conductrice 50 assure, via les contacts de détection, la continuité électrique entre les deux demi-plaques conductrices 30, 31 du support mobile d'actionnement 3. Lorsque le support mobile d'actionnement 3 et le support mobile de détection 5 sont dans leur position de fermeture, le circuit électrique est fermé. The mobile actuating support 3 and the movable detection support 5 are displaceable in translation along the control axis (X). The movable actuating support 3 is initially in a closed position in which its actuating contacts are closed and is able to move to an open position in which its actuating contacts are open. The mobile detection support 5 is initially in an open position in which its detection contacts are open and is able to move to a closed position in which its detection contacts are closed. When the mobile detection support 5 is in the closed position, the conductive part 50 provides, via the detection contacts, the electrical continuity between the two conductive half-plates 30, 31 of the mobile operating support 3. When the mobile support 3 and the movable detection support 5 are in their closed position, the electric circuit is closed.
L'ensemble de commutation principal 2a comporte un dispositif d'actionnement coopérant avec l'organe d'actionnement 10 de l'ensemble de commande 1 . Ce dispositif comprend un poussoir d'actionnement 8 et un poussoir de
détection 9 agencés pour agir respectivement sur le support mobile d'actionnement 3 et sur le support mobile de détection 5. The main switching assembly 2a comprises an actuating device cooperating with the actuating member 10 of the control unit 1. This device comprises an actuating pusher 8 and a pusher detection 9 arranged to act respectively on the mobile operating support 3 and on the mobile detection support 5.
Le poussoir d'actionnement 8 est susceptible d'être actionné par l'organe d'actionnement 10 pour ouvrir le circuit électrique. Le poussoir de détection 9 est susceptible d'être actionné lorsque l'ensemble de commande 1 est connecté mécaniquement sur l'ensemble de commutation principal 2a, de manière à déplacer le support mobile de détection 5 pour fermer le circuit électrique. The actuating pusher 8 can be actuated by the actuating member 10 to open the electric circuit. The sensing pusher 9 is operable when the control assembly 1 is mechanically connected to the main switching assembly 2a, so as to move the movable sensing support 5 to close the electrical circuit.
Selon l'invention, les deux poussoirs 8, 9 sont coaxiaux et imbriqués, le poussoir de détection 9 étant apte à coulisser dans le poussoir d'actionnement 8. Les deux poussoirs 8, 9 sont susceptibles de prendre chacun une position de repos dans laquelle ils sont saillants à l'extérieur du bloc de contacts et une position de travail dans laquelle ils sont déplacés vers l'intérieur du bloc de contacts. According to the invention, the two pushers 8, 9 are coaxial and nested, the detection pushbutton 9 being able to slide in the actuating pusher 8. The two pushers 8, 9 are each capable of taking a rest position in which they protrude outside the contact block and a working position in which they are moved inwardly of the contact block.
Le poussoir de détection 9 (figure 6) comporte une partie haute constituée d'une tête 90 contre laquelle peut venir s'appuyer l'organe d'actionnement 10 de l'ensemble de commande 1 , prolongée d'une partie intermédiaire formée de deux montants parallèles réalisant un mécanisme de glissière pour la pièce conductrice 50 du support mobile de détection 5, le ressort de pression de contacts 7 prenant appui d'une part contre le support mobile de détection 5 et d'autre part contre la tête 90 du poussoir de détection 9. Le poussoir de détection 9 se termine par une partie basse dans laquelle vient se loger le ressort d'ouverture 6, ce dernier étant agencé entre le support mobile d'actionnement 3 et le poussoir de détection 9. Le poussoir de détection 9 et le support mobile de détection 5 sont ainsi agencés de manière à pouvoir coulisser l'un par rapport à l'autre suivant l'axe de commande (X). The detection pusher 9 (FIG. 6) comprises an upper part consisting of a head 90 against which the actuating member 10 of the control assembly 1 can be supported, extended by an intermediate portion formed of two parallel uprights providing a slide mechanism for the conductive part 50 of the mobile detection support 5, the contact pressure spring 7 bearing on the one hand against the movable detection support 5 and on the other hand against the head 90 of the pusher 9. The detection pusher 9 ends with a lower part in which the opening spring 6 is housed, the latter being arranged between the mobile actuating support 3 and the detection pusher 9. The detection pusher 9 and the movable detection support 5 are thus arranged so as to slide relative to each other along the control axis (X).
Le poussoir d'actionnement 8 (figure 6) comporte un corps principal parallélépipédique muni sur deux faces opposées de deux ailettes 80 symétriques destinées à s'appuyer contre le corps 20 du bloc de contacts lorsqu'il est sollicité par le ressort d'ouverture 6 vers sa position de repos. Il comporte également une ouverture centrale 81 à l'intérieur de laquelle est agencé le poussoir de détection 9, la tête 90 du poussoir de détection 9 comportant une collerette maintenue en appui contre le poussoir d'actionnement grâce au ressort d'ouverture 6. Le poussoir d'actionnement 8 comporte également deux organes 82 symétriques s'étendant de manière saillante, parallèlement à l'axe de commande (X), en direction du support mobile d'actionnement.
En liaison avec les figures 2A à 5B, le principe de fonctionnement de l'invention est le suivant : The actuating pusher 8 (FIG. 6) comprises a parallelepipedal main body provided on two opposite faces with two symmetrical fins 80 intended to bear against the body 20 of the contact block when it is urged by the opening spring 6. towards his rest position. It also comprises a central opening 81 inside which the detection pusher 9 is arranged, the head 90 of the detection pusher 9 comprising a collar held in abutment against the actuating pusher by means of the opening spring 6. The actuating pusher 8 also comprises two symmetrical members 82 protrudingly extending, parallel to the control axis (X), in the direction of the movable actuating support. In connection with FIGS. 2A to 5B, the operating principle of the invention is as follows:
Figures 2A et 2B Figures 2A and 2B
Lorsque l'ensemble de commande 1 est déconnecté mécaniquement de l'ensemble de commutation principal 2a, les deux poussoirs 8, 9 sont en position de repos. Le poussoir de détection 9 est sollicité vers sa position de repos par le ressort d'ouverture 6 et entraîne le poussoir d'actionnement 8 vers sa position de repos. Le poussoir de détection 9, sollicité vers sa position de repos par le ressort d'ouverture 6, maintient le support mobile de détection 5 en position d'ouverture. When the control unit 1 is mechanically disconnected from the main switching assembly 2a, the two pushers 8, 9 are in the rest position. The detection pushbutton 9 is biased towards its rest position by the opening spring 6 and drives the actuating pusher 8 towards its rest position. The detection push-button 9, biased towards its rest position by the opening spring 6, keeps the mobile detection support 5 in the open position.
Figures 3A et 3B Figures 3A and 3B
L'ensemble de commande 1 est assemblé mécaniquement sur l'ensemble de commutation principal 2a, ce qui entraîne le poussoir de détection 9 vers l'intérieur du bloc de contacts à rencontre du ressort d'ouverture 6. Sous l'action du poussoir de détection 9 et du ressort de pression de contacts 7, le support mobile de détection 5 descend en position de fermeture. Le poussoir d'actionnement 8, libéré de la pression exercée par le poussoir de détection 9 via le ressort d'ouverture 6, descend pour venir s'appuyer via ses organes 82 sur le support mobile d'actionnement 3. The control assembly 1 is mechanically assembled on the main switching assembly 2a, which causes the detection push-button 9 towards the inside of the contact block to meet the opening spring 6. Under the action of the push-button detection 9 and the contact pressure spring 7, the movable detection support 5 goes down in the closed position. The actuating pusher 8, released from the pressure exerted by the detection pusher 9 via the opening spring 6, descends to come to bear via its members 82 on the mobile actuating support 3.
Le commutateur d'actionnement et le commutateur de détection sont alors fermés, le dispositif d'arrêt d'urgence est donc correctement assemblé et prêt à fonctionner. The actuation switch and the sense switch are then closed, thus the emergency stop device is correctly assembled and ready for operation.
Figures 4A et 4B Figures 4A and 4B
Alors que l'ensemble de commande 1 est assemblé mécaniquement sur l'ensemble de commutation principal 2a, une pression sur l'organe d'actionnement 10 de l'ensemble de commande 1 entraîne d'abord le poussoir de détection 9 entièrement à l'intérieur du poussoir d'actionnement 8 en réduisant la surcourse du poussoir de détection 9 par compression du ressort 7 de pression de contacts. Le commutateur de détection et le commutateur d'actionnement restent fermés. While the control assembly 1 is mechanically assembled to the main switching assembly 2a, pressing the actuating member 10 of the control assembly 1 first drives the sensing pusher 9 fully to the inside the actuating pusher 8 by reducing the overtravel of the sensing pusher 9 by compression of the contact pressure spring 7. The detection switch and the operation switch remain closed.
Figures 5A et 5B
En continuant d'appuyer sur l'organe d'actionnement 10 de l'ensemble de commande 1 , celui-ci entraîne l'ensemble formé du poussoir d'actionnement 8 et du poussoir de détection 9 vers l'intérieur du bloc de contacts. Le poussoir d'actionnement 8 étant alors déjà en appui sur le support mobile d'actionnement 3 (cf. figure 3B), celui- ci appuie alors sur le support mobile d'actionnement 3 et l'entraîne jusqu'à sa position d'ouverture à rencontre du ressort principal 4. Le commutateur d'actionnement est donc ouvert. Le commutateur de détection reste pour sa part en position de fermeture. Figures 5A and 5B Continuing to press the actuating member 10 of the control unit 1, the latter drives the assembly formed by the actuating pusher 8 and the detection pusher 9 towards the inside of the block of contacts. The actuating pusher 8 is then already resting on the movable actuating support 3 (see FIG. 3B), which then bears against the movable actuating support 3 and drives it to its position. opening against main spring 4. The actuating switch is thus open. The detection switch remains in the closed position.
Par conséquent, il est possible de surveiller l'accrochage de l'ensemble de commande 1 sur l'ensemble de commutation principal 2a en ouvrant le commutateur de détection lorsque l'ensemble de commande 1 est déconnecté mécaniquement de l'ensemble de commutation 2a tout en ne perturbant pas le fonctionnement normal du dispositif lorsque l'ensemble de commande 1 est correctement assemblé sur l'ensemble de commutation principal 2a. Therefore, it is possible to monitor the latching of the control assembly 1 on the main switching assembly 2a by opening the detection switch when the control assembly 1 is mechanically disconnected from the switching assembly 2a while by not disturbing the normal operation of the device when the control assembly 1 is correctly assembled on the main switching assembly 2a.
Par ailleurs, pour sécuriser l'assemblage de chaque ensemble de commutation auxiliaire 2b, 2c adjacent, l'ensemble de commutation principal 2a comporte des moyens mécaniques coopérant avec la face arrière f1 1 , f21 de chaque ensemble de commutation auxiliaire 2b, 2c. Ces moyens mécaniques comportent par exemple une partie saillante réalisée sur le boîtier 20 de l'ensemble de commutation principal 2a et destinée à venir en contact avec la face arrière f1 1 , f21 de chaque ensemble de commutation auxiliaire 2b, 2c adjacent. Cette partie saillante est par exemple constituée d'au moins une ailette 220, 221 (deux ailettes sur les figures) réalisée sur une face latérale f3, f4 du boîtier 20 de l'ensemble de commutation principal 2a et formant une surface d'appui s'étendant de manière perpendiculaire à l'axe de fixation ou, autrement dit, parallèlement à la face arrière f2 du boîtier 20. Comme le dispositif d'arrêt d'urgence peut comporter deux ensembles de commutation auxiliaires dont l'accrochage doit être sécurisé, l'ensemble de commutation principal 2a comporte une ailette 220, 221 sur chacune de ses faces latérales f3, f4. Les deux ailettes 220, 221 sont réalisées symétriquement sur chaque face latérale f3,f4 du boîtier de l'ensemble de commutation principal 2a et permettent ainsi de sécuriser en même temps l'accrochage des deux ensembles de commutation auxiliaires 2b, 2c. Furthermore, to secure the assembly of each adjacent auxiliary switching assembly 2b, 2c, the main switching assembly 2a comprises mechanical means cooperating with the rear face f1 1, f21 of each auxiliary switching assembly 2b, 2c. These mechanical means comprise for example a protruding part made on the housing 20 of the main switching assembly 2a and intended to come into contact with the rear face f1 1, f21 of each adjacent auxiliary switching assembly 2b, 2c. This protruding portion is for example constituted by at least one fin 220, 221 (two fins in the figures) made on a lateral face f3, f4 of the housing 20 of the main switching assembly 2a and forming a bearing surface. extending perpendicularly to the fastening axis or, in other words, parallel to the rear face f2 of the housing 20. As the emergency stop device may comprise two auxiliary switching assemblies whose attachment must be secured, the main switching assembly 2a comprises a fin 220, 221 on each of its lateral faces f3, f4. The two fins 220, 221 are made symmetrically on each side face f3, f4 of the housing of the main switching assembly 2a and thus make it possible to secure at the same time the attachment of the two auxiliary switching assemblies 2b, 2c.
Selon l'invention, la présence de ces ailettes 220, 221 sur l'ensemble de commutation principal 2a oblige à accrocher d'abord les ensembles de commutation
auxiliaires 2b, 2c sur l'ensemble de commande 1 puis d'accrocher l'ensemble de commutation principal 2a qui, s'il est bien accroché, sécurise l'accrochage des ensembles de commutation auxiliaires 2b, 2c qui sont adjacents.
According to the invention, the presence of these fins 220, 221 on the main switching assembly 2a makes it necessary to first hook up the switching assemblies. auxiliaries 2b, 2c on the control assembly 1 and then hook the main switching assembly 2a which, if it is hooked, secures the attachment of adjoining auxiliary switching assemblies 2b, 2c.
