Description

La présente invention concerne une capsuleuse manuelle, utilisable notamment pour la mise en place de capsules sur les nez filetés de robinets de bouteilles de gaz sous pression.The present invention relates to a manual capper, which can be used in particular for placing capsules on the threaded noses of taps of pressurized gas bottles.

Lorsque des bouteilles sortent de l'installation de remplissage en gaz liquéfié, leurs robinets doivent être pourvus d'une capsule destinée à remplir une double fonction d'étanchéité et d'anti-violation. Cette capsule est constituée d'une coupelle en aluminium ou autre matériau déformable, pourvue d'une languette d'arrachement; le fond de la coupelle comporte un joint d'étanchéité remplissant sa fonction quand la capsule est fixée par sertissage sur le nez de robinet. Il existe à l'heure actuelle une machine pour effectuer automatiquement le capsulage des robinets de bouteilles sur la ligne de remplissage mais, lorsque cette machine est en indisponibilité, on ne peut évidemment plus fixer de capsules et il faut alors visser sur les nez de robinets des bouchons filetés qui ne remplissent pas la même fonction que les capsules.When bottles come out of the liquefied gas filling installation, their valves must be provided with a cap intended to fulfill a double sealing and anti-violation function. This capsule consists of a cup made of aluminum or other deformable material, provided with a tearing tab; the bottom of the cup has a gasket fulfilling its function when the capsule is fixed by crimping on the tap nose. There is currently a machine for automatically capping the bottle valves on the filling line but, when this machine is unavailable, it is obviously no longer possible to fix capsules and it is then necessary to screw on the valve noses threaded plugs which do not fulfill the same function as the capsules.

Pour remédier à cet inconvénient, il est prévu, conformément à la présente invention une capsuleuse manuelle à commande fluidique qui comprend un bâti, notamment en forme de col de cygne, pourvu d'une poignée de manoeuvre, une tête de sertissage qui est mobile dans le bâti et qui coopère avec une enclume fixée dans le bâti, un dispositif de support, d'actionnement fluidique et de guidage de la tête de sertissage, un mécanisme de rappel de ladite tête et un dispositif de commande fluidique pourvus de moyens logiques de régulation et de sécurité.To overcome this drawback, there is provided, in accordance with the present invention, a manual capper with fluid control which comprises a frame, in particular in the form of a swan neck, provided with an operating handle, a crimping head which is movable in the frame and which cooperates with an anvil fixed in the frame, a support device, fluid actuation and guiding of the crimping head, a mechanism for returning said head and a fluid control device provided with logic regulation means and security.

La capsuleuse selon l'invention peut encore présenter les caractéristiques ci-après, considérées isolément ou selon toutes leurs combinaisons techniquement possibles :

  • - la tête de sertissage comprend un piston déplaçable à l'intérieur d'un manchon de guidage et coopérant avec un fourreau coulissant sur la surface extérieure du manchon pour actionner une garniture souple de sertissage, placée à l'extrémité de la tête, de façon qu'elle s'appuie contre la capsule et l'applique étroitement contre la périphérie et l'extrémité du nez de robinet en assurant ainsi son sertissage.
  • - le dispositif d'actionnement fluidique et de guidage de la tête de sertissage comprend un vérin pneumatique, notamment en forme de vessie plate gonflable, placé entre un plateau fixe, relié au bâti par des tiges de guidage et un plateau mobile de poussée, coulissant sur lesdites tiges de guidage et sur lequel est fixé ledit manchon de guidage de la tête de sertissage.
  • - il est prévu dans le manchon de guidage un butoir contre lequel vient buter le piston de sertissage, après compression d'un ressort de rappel intermédiaire.
  • - il est prévu sur la surface extérieure du manchon de guidage un épaulement servant à actionner le fourreau extérieur de la tête de sertissage en fin de cycle.
  • - pour assurer le retour du dispositif de support et d'actionnement de la tête de sertissage dans la position initiale, il est prévu un ou plusieurs ressorts de rappel agissant en compression entre le bâti et le plateau mobile de poussée.
  • - pour assurer ce mouvement de retour, il est prévu un ou plusieurs vérins fluidiques de rappel dont le cylindre est fixé sur ledit bâti et dont le piston est relié par une tige au plateau mobile de poussée.
  • - le dispositif de commande fluidique comprend une gâchette opérant par maintien d'un contacteur fluidique en condition de service, un temporisateur de réglage du cycle de sertissage, un distributeur de commande du vérin principal, un distributeur de commande du vérin de rappel, un distributeur d'asservissement et un circuit logique de sécurité pour arrêter la capsuleuse en cours de cycle.
The capper according to the invention can also have the following characteristics, considered in isolation or in all their technically possible combinations:
  • - the crimping head comprises a piston displaceable inside a guide sleeve and cooperating with a sliding sleeve on the external surface of the sleeve to actuate a flexible crimping lining, placed at the end of the head, so she relies on be the capsule and apply it tightly against the periphery and the end of the tap nose, thus ensuring its crimping.
  • - the fluid actuation and guiding device of the crimping head comprises a pneumatic cylinder, in particular in the form of an inflatable flat bladder, placed between a fixed plate, connected to the frame by guide rods and a movable thrust plate, sliding on said guide rods and on which said guide sleeve of the crimping head is fixed.
  • - There is provided in the guide sleeve a stop against which abuts the crimping piston, after compression of an intermediate return spring.
  • - There is provided on the outer surface of the guide sleeve a shoulder for actuating the outer sheath of the crimping head at the end of the cycle.
  • - To ensure the return of the support and actuation device of the crimping head in the initial position, there are provided one or more return springs acting in compression between the frame and the movable thrust plate.
  • - To ensure this return movement, one or more return fluid cylinders are provided, the cylinder of which is fixed to said frame and the piston of which is connected by a rod to the movable thrust plate.
  • - the fluid control device comprises a trigger operating by maintaining a fluid contactor in service condition, a setting timer for the crimping cycle, a control valve for the main cylinder, a control valve for the return cylinder, a distributor and a logic safety circuit to stop the capper during the cycle.

Dans l'exemple de réalisation des figures 1 et 2, la capsuleuse comporte essentiellement un bâti 1 en forme de col de cygne, pourvu à son extrémité arrière d'une poignée 4 suspendue par l'intermédiaire d'un crochet 6 à un câble 7 lui-même relié à une potence, non représentée. Le bâti 1 porte d'un côté le dispositif d'actionnement pneumatique 2 de la tête de sertissage 12 et de l'autre côté l'enclume 3 qui est fixe . Il est en outre prévu un dispositif de rappel 9 pour ramener la tête de sertissage dans la position initiale et un coffret de commande pneumatique 10 indiqué schématiquement sur la figure 1 et dont les composants seront décrits en détail dans la suite en référence au schéma de circuit de la figure 3. La capsuleuse/comman- dée à l'aide d'une gâchette 5 qui agit sur un contacteur pneumatique 8.In the embodiment of Figures 1 and 2, the capper essentially comprises a frame 1 in the form of a swan neck, provided at its rear end with a handle 4 suspended by means of a hook 6 from a cable 7 itself connected to a gallows, not shown. The frame 1 carries on one side the pneumatic actuating device 2 of the crimping head 12 and on the other side the anvil 3 which is fixed. There is also a return device 9 for returning the crimping head to the initial position and a pneumatic control unit 10 indicated diagrammatically in FIG. 1 and the components of which will be described in detail below with reference to the circuit diagram. of FIG. 3. The capper / controlled by means of a trigger 5 which acts on a pneumatic contactor 8.

On va maintenant décrire de façon détaillée la tête de sertissage de capsule et son dispositif d'actionnement et guidage.We will now describe in detail the capsule crimping head and its actuating and guiding device.

La tête de sertissage comprend une partie 11 en forme de piston coulissant à l'intérieur d'un manchon de guidage 16 et pourvue d'un côté d'un embout 13 dont la fonction sera précisée dans la suite. Le piston 11 agit de l'autre côté sur une calotte souple 29 maintenue en bout du manchon de guidage 16 de manière à l'appliquer contre une capsule C placée sur un nez N de robinet R (représenté en traits mixtilignes à la figure 1). En outre il est prévu à l'extérieur du manchon 16 un fourreau 28 dont le mouvement de coulissement sur le manchon est guidé par un téton, schématisé en 35 et se déplaçant dans une fente pa- te parallèle à l'axe du manchon 16. Ce fourreau 28 a pour fonction, en fin de course de sertissage, d'appliquer étroitement la calotte souple 29 contre et autour de la capsule pour que celle-ci épouse le profil du nez de robinet dans sa partie latérale filetée.The crimping head comprises a part 11 in the form of a piston sliding inside a guide sleeve 16 and provided on one side with a nozzle 13 whose function will be explained below. The piston 11 acts on the other side on a flexible cap 29 held at the end of the guide sleeve 16 so as to apply it against a capsule C placed on a nose N of valve R (shown in mixed lines in Figure 1) . In addition, there is provided outside the sleeve 16 a sheath 28 whose sliding movement on the sleeve is guided by a stud, shown diagrammatically at 35 and moving in a slit pa- you parallel to the axis of the sleeve 16. The function of this sleeve 28, at the end of the crimping stroke, is to apply the flexible cap 29 tightly against and around the capsule so that it conforms to the profile of the tap nose in its threaded side part.

Le dispositif d'actionnement 2 de la tête de sertissage 12 comprend un vérin de profil aplati en forme de vessie plate gonflable, notamment un vérin connu sous la désignation commerciale PRONAL; ce vérin alimenté par l'intermédiaire de la tubulure 23, est placé entre un plateau fixe 21, relié par des tiges de guidage 31,32, au bâti 1 de la capsuleuse, et un plateau mobile 22, pouvant coulisser sur lesdites tiges 31, 32. Sur ce plateau mobile 22 est fixé le manchon de guidage 16 de la tête de sertissage 12 par l'intermédiaire de vis schématisées en 34. Le manchon 16 coulisse dans un fût de guidage 15, représenté seulement de façon schématique et fixé dans la platine arrière 18 du bâti 1 de la capsuleuse.The actuation device 2 of the crimping head 12 comprises a cylinder of flattened profile in the form of an inflatable flat bladder, in particular a cylinder known under the commercial designation PRONAL; this jack supplied via the tubing 23 is placed between a fixed plate 21, connected by guide rods 31, 32, to the frame 1 of the capper, and a mobile plate 22, which can slide on said rods 31, 32. On this movable plate 22 is fixed the guide sleeve 16 of the crimping head 12 by means of screws shown diagrammatically at 34. The sleeve 16 slides in a guide barrel 15, shown only schematically and fixed in the rear plate 18 of frame 1 of the capper.

A l'intérieur du manchon 16 est fixé, à l'aide d'une goupille 25', un butoir 25 pourvu d'un embout 24 contre lequel vient buter, au cours du cycle de sertissage, le piston 11 après compression d'un ressort de rappel intermédiaire 14. Sur la surface extérieure du manchon 16, il est prévu un épaulement 27 qui a pour fonction, vers la fin du cycle de sertissage, de pousser vers l'avant le fourreau extérieur 28 de la tête 12 pour assurer l'enveloppement de la capsule C par la garniture extrême 29.Inside the sleeve 16 is fixed, using a pin 25 ', a stopper 25 provided with a tip 24 against which abuts, during the crimping cycle, the piston 11 after compression of a intermediate return spring 14. On the outer surface of the sleeve 16, there is provided a shoulder 27 which has the function, towards the end of the crimping cycle, of pushing forward the outer sheath 28 of the head 12 to ensure the wrapping of the capsule C by the extreme lining 29.

En regard de la tête de sertissage 12, il est prévu à l'extrémité du col de cygne du bâti 1 une enclume fixe 3 qui entre en contact avec le robinet R par l'intermédiaire d'une saillie 30 afin de le maintenir pendant le cycle de sertissage.Opposite the crimping head 12, there is provided at the end of the swan neck of the frame 1 a fixed anvil 3 which comes into contact with the tap R via a projection 30 in order to maintain it during the crimping cycle.

Une fois le cycle de sertissage terminé, il faut que l'ensemble de la tête de sertissage 12 et du dispositif d'actionnement revienne dans la position initiale. Il est possible d'utiliser à cet effet un ou plusieurs ressorts de rappel qui sont comprimés par la partie mobile du dispositif pendant la course de sertissage et qui se détendent ensuite pour la ramener en condition initiale. Cependant cette compression des ressorts pendant la course de sertissage absorbe une partie de l'énergie du vérin 17 et se traduit ensuite par une brusque détente des ressorts pendant le mouvement de retour et par conséquent par un choc important en fin de course. Aussi, conformément à une caractéristique de la capsuleuse selon l'invention, il est prévu, pour assurer le rappel de la partie mobile du dispositif, un vérin pneumatique 9 dont le cylindre est fixé sur la platine arrière 18 du bâti et dans lequel coulisse un piston 19 relié par une tige 20 au plateau mobile 22 portant le manchon 16. En fin de course de sertissage, ce vérin de rappel 9 est alimenté en air par le dispositif de commande 10 et assure un mouvement uniforme de retour du dispositif jusque dans la position initiale, avec aplatissement du vérin principal 17.Once the crimping cycle has ended, all of the crimping head 12 and the actuating device must return to the initial position. It is possible to use for this purpose one or more return springs which are compressed by the movable part of the device during the crimping stroke and which then relax to bring it back to the initial condition. However, this compression of the springs during the crimping stroke absorbs part of the energy of the jack 17 and then results in a sudden relaxation of the springs during the return movement and consequently by a significant shock at the end of the stroke. Also, in accordance with a characteristic of the capper according to the invention, there is provided, to ensure the return of the movable part of the device, a pneumatic cylinder 9 whose cylinder is fixed to the rear plate 18 of the frame and in which slides a piston 19 connected by a rod 20 to the movable plate 22 carrying the sleeve 16. At the end of the crimping stroke, this return cylinder 9 is supplied with air by the control device 10 and ensures a uniform return movement of the device as far as the initial position, with flattening of the main cylinder 17.

On va maintenant décrire la structure et le fonctionnement du dispositif de commande 10 de la capsuleuse, en référence au schéma de circuit pneumatique donné à titre d'exemple sur la figure 3. A cet égard il est d'ailleurs à noter que le circuit pourrait être également du type hydraulique. Comme le montre la figure 3, l'air comprimé entre en 36 et alimente en parallèle plusieurs éléments, notamment le contacteur pneumatique 8 de la gâchette 5. Quand celle-ci est actionnée, l'air comprimé parvient par l'intermédiaire du raccord 37 d'une part au temporisateur T et d-'autre part au distributeur D1, du type 5/2 différentiel dans l'exemple considéré, qui subit alors un pilotage sans laisser passer l'air. Le temporisateur est enclenché, c'est-à-dire ouvert et l'air parvient ainsi d'une part à l'autre extrémité du distributeur D1 de façon à manoeuvrer son tiroir et établir la liaison avec le distributeur D2 de commande de vérin principal 17, et d'autre part à l'entrée du distributeur D3, du type 5/2 bistable, servant à commander le vérin de rappel 9 mais qui est alors simplement piloté.We will now describe the structure and operation of the control device 10 of the capper, with reference to the pneumatic circuit diagram given by way of example in FIG. 3. In this regard it should also be noted that the circuit could also be of the hydraulic type. As shown in FIG. 3, the compressed air enters at 36 and feeds in parallel several elements, in particular the pneumatic contactor 8 of the trigger 5. When the latter is actuated, the compressed air arrives via the connector 37 on the one hand to the timer T and on the other hand to the distributor D 1 , of the 5/2 differential type in the example considered, which then undergoes piloting without letting the air pass. The timer is engaged, that is to say open and the air thus reaches on the one hand at the other end of the distributor D 1 so as to operate its drawer and establish the connection with the distributor D 2 for controlling main cylinder 17, and on the other hand at the entrance to the distributor D 3 , of the bistable 5/2 type, used to control the return cylinder 9 but which is then simply controlled.

Si tout est normal, la liaison 38-39-40-41 est alors établie avec le vérin 17 qui est par conséquent actionné et le cycle de sertissage est amorcé; le vérin précité peut exercer une force élevée, par exemple de 1 tonne. A la fin du cycle de sertissage, définie par le temporisateur réglagle T, il n'y a plus pilotage du distributeur D3 qui assure alors par l'intermédiaire du tuyau 46 l'alimentation de la cellule OU-47 et par conséquent, si tout est normal, du vérin pneumatique 9 de rappel de tête de sertissage 12. Celui-ci ramène alors le dispositif d'actionnement 2 en position initiale par l'intermédiaire de la tige 40.If everything is normal, the link 38-39-40-41 is then established with the jack 17 which is therefore actuated and the crimping cycle is initiated; the aforementioned cylinder can exert a high force, for example of 1 ton. At the end of the crimping cycle, defined by the adjustable timer T, there is no longer control of the distributor D 3 which then ensures, via the hose 46, the supply of the cell OU-47 and therefore, if everything is normal, from the pneumatic cylinder 9 for returning the crimping head 12. The latter then brings the actuating device 2 back to the initial position by means of the rod 40.

Si pour une raison quelconque d'insécurité, de mauvais positionnement de la capsule, ou autre, l'opérateur décide d'arrêter prématurément le cycle de sertissage, il est prévu un système de sécurité qui va maintenant être décrit. La gâchette 5 est du type à maintien continu en pression par la main de l'opérateur pendant tout le cycle de sertissage. Pour arrêter prématurément ce cycle, il lui suffit de relâcher la gâchette, ce qui provoque l'enclenchement du système de sécurité constitué par la cellule NON-49, normalement fermée, et le distributeur D4, du type 3/2 à rappel par ressort dans l'exemple considéré , Ce système intervient de la façon suivante : quand la gâchette est relâchée , la voie 38-39-40-41, et par conséquent 42, n'est plus alimentée en air. La cellule NON-49, ne recevant plus deux signaux pneumatiques à ses entrées, commute dans la condition d'ouverture et alimente le distributeur qui fournit alors de l'air, par l'intermédiaire de la cellule OU-47, au vérin de rappel 9 qui ramène la capsuleuse en-condition initiale en opérant ainsi dans le sens de la sécurité.If for any reason of insecurity, improper positioning of the capsule, or the like, the operator decides to prematurely stop the crimping cycle, a safety system is provided which will now be described. The trigger 5 is of the type with continuous pressure maintenance by the hand of the operator throughout the crimping cycle. To stop this cycle prematurely, he just has to release the trigger, which triggers the safety system consisting of the NON-49 cell, normally closed, and the D 4 valve, of the 3/2 type with spring return In the example considered, this system operates as follows: when the trigger is released, the channel 38-39-40-41, and consequently 42, is no longer supplied with air. The NON-49 cell, no longer receiving two pneumatic signals at its inputs, switches to the open condition and supplies the distributor which then supplies air, via the OU-47 cell, to the return cylinder 9 which brings the capper back to its initial condition, thus operating in the direction of safety.

La description ci-dessus montre que la capsuleuse selon l'invention est d'un fonctionnement très efficace et très sûr. Pour améliorer encore la maniabilité de l'appareil, on peut fixer par tout moyen approprié, non représenté sur les dessins, un fourreau dont l'axe est parallèle à la ligne d'action du dispositif de capsulage et qui est dimensionné de façon à permettre d'abord le passage de la main de l'opérateur et ensuite le maintien de son avant-bras pendant la manoeuvre de la capsuleuse et son actionnement à l'aide de la gâchette.The above description shows that the capper according to the invention is very efficient and very safe to operate. To further improve the maneuverability of the apparatus, a sheath whose axis is parallel to the line of action of the capping device and which is dimensioned so as to allow it to be fixed by any suitable means, not shown in the drawings first the hand of the operator and then the maintenance of his forearm during the operation of the capper and its actuation using the trigger.

Bien entendu l'invention n'est pas limitée au mode de réalisation décrit et toutes modifications et variantes à la portée de l'homme de l'art ne sortent pas du cadre de l'invention.Of course, the invention is not limited to the embodiment described and any modifications and variants within the reach of those skilled in the art do not depart from the scope of the invention.
