Description

La présente invention concerne l'extrusion de tous les produits pâteux tels que les mastics d'étanchéité, les colles, graisses etc... stockés dans des cartouches standards.The present invention relates to the extrusion of all pasty products such as sealants, glues, greases, etc. stored in standard cartridges.

Pour extraire les produits considérés de leur emballage on utilise généralement des pistolets mécaniques ou à air comprimé destinés à agir sur le fond mobile de la cartouche en vue de le déplacer axialement.To extract the products under consideration from their packaging, mechanical or compressed air guns are generally used intended to act on the movable bottom of the cartridge in order to move it axially.

Lorsqu'on on a affaire à des pistolets mécaniques l'éjection du produit manque de précision. De plus son utilisation est difficile pour un professionnel qui doit utiliser un grand nombre de cartouches. En outre la pression sur la gâchette doit être beaucoup plus forte en hiver quand le produit est un peu figé. Après avoir stoppé la pression sur la gâchette, le mastic continue de sortir du fait de la pression qui règne dans la cartouche.When dealing with mechanical guns the ejection of the product lacks precision. In addition, its use is difficult for a professional who must use a large number of cartridges. In addition the pressure on the trigger must be much stronger in winter when the product is a little frozen. After stopping the pressure on the trigger, the sealant continues to come out due to the pressure in the cartridge.

On utilise aussi des pistolets à air comprimé produit par un compresseur. Ce type de pistolet gaspille une grande quantité d'air du fait de son fonctionnement. En effet afin de neutraliser la pression exercée derrière le fond mobile de la cartouche et en vue d'arrêter net la sortie du produit il est nécessaire chaque fois qu'on relâche la gâchette d'effectuer une vidange de l'air à l'arrière du fond mobile de la cartouche. Ceci nécessite l'utilisation obligatoire d'un compresseur qui débite sans compter des milliers de litres d'air comprimé.Air pistols produced by a compressor are also used. This type of gun wastes a large amount of air due to its operation. Indeed in order to neutralize the pressure exerted behind the movable bottom of the cartridge and in order to stop the output of the product clean it is necessary each time that the trigger is released to drain the air at the rear of the movable bottom of the cartridge. This requires the compulsory use of a compressor which delivers thousands of liters of compressed air without counting.

L'inconvénient majeur de ces pistolets est tout d'abord la présence indispensable d'un compresseur qui n'est pas toujours très facile à transporter notamment en étage et dont le fonctionnement est très bruyant. En outre l'arrêt de la sortie du produit pâteux n'est pas obtenu très nettement car la vidange de l'air sous le fond mobile de la cartouche n'est pas instantanée. D'une manière générale l'utilisation d'un pistolet à air comprimé est d'un prix de revient très élevé.The major drawback of these guns is first of all the essential presence of a compressor which is not always very easy to transport, especially upstairs and whose operation is very noisy. In addition, stopping the outlet of the pasty product is not very clearly obtained because the air is emptied under the movable bottom of the cartridge. is not instant. In general, the use of an air pistol is a very high cost price.

De tels pistolets sont décrits dans le brevet français 1.508.882 et dans la demande française 2.301.306.Such pistols are described in French patent 1,508,882 and in French application 2,301,306.

Dans le premier document on montre que le débouché de la cartouche est associé à un tube souple sur l'extrémié duquel est monté l'injecteur destiné au déversement du produit pâteux. En déplaçant une gâchette on déforme mécaniquement le tube afin d'arrêter le déversement de la matière. Lorsque l'appareil doit être posé et qu'en conséquence la gâchette n'est plus actionnée il est nécessaire de couper l'arrivée d'air sous le fond mobile de la cartouche sinon le produit pâteux continue à se déverser. Cette opération entraîne bien entendu la vidange du volume situé sous le fond mobile de la cartouche sinon le produit pâteux continuerait à se déverser même après fermeture de l'arrivée d'air du fait de la pression régnant dans ce volume.In the first document it is shown that the outlet of the cartridge is associated with a flexible tube on the end of which is mounted the injector intended for the pouring of the pasty product. By moving a trigger, the tube is mechanically deformed in order to stop the spillage of the material. When the device has to be installed and that consequently the trigger is no longer actuated it is necessary to cut off the air supply under the movable bottom of the cartridge otherwise the pasty product continues to spill. This operation of course results in the emptying of the volume located under the movable bottom of the cartridge otherwise the pasty product would continue to spill even after closing the air supply due to the pressure prevailing in this volume.

Dans le second document l'embout rigide avec lequel coopère la sortie de la cartouche est pourvu d'un simple robinet à boisseau qui ouvre ou ferme cet embout afin que la matière puisse ou non être éjectée. Un tel robinet ne nécessite pas la purge du volume situé en dessous du fond mobile de la cartouche mais sa manipulation du robinet entraîne d'une part l'obligation pour l'utilisateur de se servir de ses deux mains et peut d'autre part être contrecarrée en cas de polymérisation de la substance dans le robinet ; dans ce cas celui-ci peut se coincer en position ouverte ou fermée.In the second document, the rigid end piece with which the outlet of the cartridge cooperates is provided with a simple ball valve which opens or closes this end piece so that the material may or may not be ejected. Such a tap does not require the purge of the volume located below the movable bottom of the cartridge, but its manipulation of the tap entails on the one hand the obligation for the user to use both hands and can on the other hand be countered in case of polymerization of the substance in the tap; in this case it can get stuck in the open or closed position.

Les perfectionnements-qui font l'objet de la présente invention visent à remédier à ces inconvénients et à assurer la réalisation d'un pistolet à mastic n'utilisant qu'une très faible quantité de gaz ce qui permet de supprimer le compresseur qui est remplacé par une petite bouteille d'azote industrielle. En outre le pistolet suivant l'invention permet en manoeuvrant une simple gâchette de fermer ou d'ouvrir un embout souple faisant suite au débouché de la cartouche, cette action étant réalisée pneumatiquement.The improvements which are the subject of the present invention aim to remedy these drawbacks and to ensure the production of a putty gun using only a very small amount of gas, which makes it possible to eliminate the compressor which is replaced. by a small industrial nitrogen bottle. In addition, the pistol according to the invention allows, by operating a simple trigger, to close or to open a flexible tip following the opening of the cartridge, this action being carried out pneumatically.

Conformément à l'invention, le piston d'un vérin à simple effet est associé à l'embout souple qui fait suite au débouché de la cartouche pour l'écraser lorsque ledit vérin est alimenté par un flux de gaz comprimé dérivé de celui qui agit sur le fond mobile de la cartouche, ledit flux étant envoyé dans le vérin considéré dès que l'utilisateur lâche une gâchette, tandis que l'actionnement de celle-ci entraîne l'arrêt dudit flux et la libération de l'embout en vue de permettre l'expulsion du produit pâteux.According to the invention, the piston of a single-acting cylinder is associated with the flexible end piece which follows the opening of the cartridge to crush it when said cylinder is supplied by a flow of compressed gas derived from the one which acts. on the movable bottom of the cartridge, said flow being sent into the jack considered as soon as the user releases a trigger, while the actuation of the latter causes said flow to stop and release the endpiece for allow the expulsion of the pasty product.

On a illustré en fig. 1 un dispositif suivant l'invention comportant une armature 24 associée à une poignée 15, ladite armature portant sur sa partie avant un bloc 1 tandis que sa partie arrière reçoit un vérin ouvert 28 .Illustrated in fig. 1 a device according to the invention comprising an armature 24 associated with a handle 15, said armature carrying on its front part a block 1 while its rear part receives an open jack 28.

Le bloc 1 qui est fixé à l'avant de l'armature 24 au moyen de deux vis 34, 35 (fig. 2) comprend un alésage longitudinal la dans lequel est engagé un tube souple 2 comportant une tête tubulaire 2a de plus grand diamètre qui prend appui sur la face interne du bloc 1 au moyen d'une collerette 2b. La tête 2a s'engage dans un lamage Ib du bloc 1. L'extrémité du tube 2 opposée à sa tête 2a dépasse hors du bloc 1 et peut recevoir une bague filetée 2c destinée par exemple à recevoir un embout de déversement non représenté.The block 1 which is fixed to the front of the frame 24 by means of two screws 34, 35 (fig. 2) comprises a longitudinal bore la in which is engaged a flexible tube 2 comprising a tubular head 2a of larger diameter which is supported on the internal face of the block 1 by means of a collar 2b. The head 2a engages in a counterbore Ib of the block 1. The end of the tube 2 opposite its head 2a projects out of the block 1 and can receive a threaded ring 2c intended for example to receive a discharge nozzle not shown.

Un autre alésage lc est ménagé dans le bloc 1 perpendiculaire ent à celui la. Cet alésage débouche sur la base du bloc 1 tandis que sa partie à plus faible diamètre aboutit dans l'alésage la. L'alésage lc reçoit un piston 4 dont la tête coopère avec la partie à grand diamètre de l'alésage lc, sa queue s'engageant dans la partie à plus faible diamètre dudit alésage. Un ressort de rappel 3 est prévu de manière qu'à l'état libre la queue du piston 4 ne se trouve pas en contact avec la périphérie du tube souple 2 (fig. 3). On remarque la présence d'un joint d'étanchéité 5 à la périphérie de la tête du piston 4 et d'un autre joint 6 disposé entre le bloc 1 et la partie avant de l'armature 24. Celle-ci comporte une perforation 24a qui aboutit sous le piston 4 par l'intermédiaire d'un canal 24b.Another bore lc is formed in the block 1 perpendicular to that la. This bore opens on the base of the block 1 while its part with a smaller diameter ends in the bore la. The bore lc receives a piston 4, the head of which cooperates with the large-diameter part of the bore lc, its tail engaging in the part with smaller diameter of said bore. A return spring 3 is provided so that in the free state the tail of the piston 4 is not in contact with the periphery of the flexible tube 2 (fig. 3). Note the presence of a seal 5 at the periphery of the piston head 4 and another seal 6 disposed between the block 1 and the front part of the frame 24. This includes a perforation 24a which ends up under the piston 4 through a channel 24b.

Comme illustré en fig. 3 le goulot d'une cartouche C s'engage à l'intérieur de la tête tubulaire 2a du tube souple 2, l'étanchéité entre la cartouche et ce tube étant faite par portée de l'épaulement de la cartouche contre la collerette 2b.As illustrated in fig. 3 the neck of a cartridge C engages inside the tubular head 2a of the flexible tube 2, the seal between the cartridge and this tube being made by bearing the shoulder of the cartridge against the flange 2b.

On a illustré en fig. 4 la position du piston 4 lorsque de l'air comprimé arrive dans la perforation 24 en provenant d'une vanne 8 fixée à l'armature 24 au niveau de sa poignée 15. On observe que le piston 4 se déplace vers le haut de manière que sa queue pince le tube souple 2 afin de le fermer de manière étanche comme on l'expliquera mieux plus loin.Illustrated in fig. 4 the position of the piston 4 when compressed air arrives in the perforation 24 from a valve 8 fixed to the frame 24 at its handle 15. It is observed that the piston 4 moves upwards so that its tail pinches the flexible tube 2 in order to close it in a sealed manner as will be explained better below.

La partie arrière de l'armature 24 supporte un vérin ouvert dont le cylindre 28 est assujetti à cette partie de l'armature par un talon 14 et une vis transversale 31. Le cylindre 28 est ouvert en direction du bloc 1 et on a engagé à l'intérieur de l'alésage de ce cylindre un piston 30 réalisé par exemple au moyen d'un élastomère. Le piston 30 comporte une lèvre périphérique 30a qui coopère de manière étanche avec l'alésage du cylindre 28. Ce piston 30 constitue butée pour un ressort 29 qui a tendance à repousser ledit piston vers l'extérieur du cylindre 28. Toutefois la course vers l'extérieur de ce piston est limitée par une vis 27 dont la tête 27a prend appui de manière étanche contre un épaulement 30b du centre du piston 30. Une rondelle d'étanchéité R peut d'ailleurs être associée à cet effet à la face de l'épaulement 30b en vis-à-vis de la tête 27a. On note la présence de deux trous longitudinaux30c, 30d faisant communiquer l'intérieur du cylindre 28 et l'extérieur de sorte que si le gaz comprimé arrive dans le cylindre 28 lorsqu'aucune cartouche n'est en place, il se produit une fuite qui empêche le retournement de la lèvre 30a.The rear part of the frame 24 supports an open jack, the cylinder 28 of which is secured to this part of the frame by a heel 14 and a transverse screw 31. The cylinder 28 is open in the direction of the block 1 and we have committed to inside the bore of this cylinder a piston 30 produced for example by means of an elastomer. The piston 30 comprises a peripheral lip 30a which cooperates in leaktight manner with the bore of the cylinder 28. This piston 30 constitutes a stop for a spring 29 which tends to push the said piston outwards from the cylinder 28. However, the race towards the exterior of this piston is limited by a screw 27, the head 27a of which bears in leaktight manner against a shoulder 30b of the center of the piston 30. A sealing washer R can moreover be associated for this purpose with the face of the 'shoulder 30b opposite the head 27a. Note the presence of two longitudinal holes 30c, 30d communicating the interior of the cylinder 28 and the exterior so that if the compressed gas arrives in the cylinder 28 when no cartridge is in place, a leak occurs which prevents the reversal of the lip 30a.

L'air comprimé arrive dans le cylindre 28 par une perforation 24c de l'armature 24 reliée à l'intérieur du cylindre considéré par un robinet à tiroir 22 illustré en fig. 7. A cet effet l'armature 24 est pouvue d'une saignée transversale 24d dont le fond comporte un perçage 24e aboutissant dans la perforation 24c (fig. 6 et 8). Dans la saignée 24 est placée un tiroir plat 34 comportant deux butées extrêmes 34a, 34b qui limitent son déplacement axial, la distance entre ces deux butées étant supérieure à la longueur de la saignée 24d. A une position du tiroir 34 le trou 24e de l'armature 24 est en correspondance avec une ouverture 34c du tiroir qui vient elle-même en face d'un trou 28a ménagé dans le cylindre 28 (fig. 8) de telle sorte que le gaz comprimé arrivant par la perforation 24c pénètre sous le piston 30. Le dessus du tiroir 34 comportant une rainure longitudinale 34d. Lorsqu'on fait subir une translation à ce tiroir on amène l'une des extrémités de la rainure 34d en vis-à-vis du trou 28a de telle sorte que l'intérieur du cylindre 28 est mis en communication avec l'extérieur (fig. 9). Bien entendu des joints d'étanchéité 35, 36 sont placés de part et d'autre du tiroir 34 respectivement autour du débouché des trous 24e et 28a. Ainsi à la position de fig. 9 du tiroir 34 on vidange le cylindre 28.The compressed air arrives in the cylinder 28 through a perforation 24c of the armature 24 connected to the interior of the cylinder consi drained by a slide valve 22 illustrated in fig. 7. To this end, the frame 24 is provided with a transverse groove 24d, the bottom of which has a bore 24e ending in the perforation 24c (FIGS. 6 and 8). In the groove 24 is placed a flat drawer 34 comprising two extreme stops 34a, 34b which limit its axial movement, the distance between these two stops being greater than the length of the groove 24d. At a position of the drawer 34 the hole 24e of the frame 24 is in correspondence with an opening 34c of the drawer which itself comes opposite a hole 28a formed in the cylinder 28 (fig. 8) so that the compressed gas arriving through the perforation 24c penetrates under the piston 30. The top of the drawer 34 having a longitudinal groove 34d. When this drawer is subjected to a translation, one of the ends of the groove 34d is brought opposite the hole 28a so that the inside of the cylinder 28 is placed in communication with the outside (fig. . 9). Of course, seals 35, 36 are placed on either side of the drawer 34 respectively around the outlet of the holes 24e and 28a. Thus at the position of fig. 9 of drawer 34 the cylinder 28 is emptied.

Les perforations 24a et 24c sont alimentées en air comprimé à partir de la vanne 8 par l'intermédiaire de tuyaux 25, respectivement 21 (fig. 1). La vanne 8 qui est fixée au-dessous de l'armature 24 au moyen d'une vis 7 comporte trois canaux 8a, 8b, 8c (fig. 10) dans lesquels sont emmanchés respectivement les tuyaux 25 et 21 ainsi qu'un tube 19 dont l'extrémité libre constitue un embout auquel est branché l'alimentation en gaz comprimé. On observe que le canal 8c débouche dans celui 8b de manière que le tuyau 21 soit alimenté directement en gaz. Un alésage étagé borgne 8d est ménagé longitudinalement dans la vanne 8. On note que la partie à plus faible diamètre de l'alésage 8d est en communication avec le canal 8c, tandis que le canal 8a débouche dans la partie à plus grand diamètre dudit alésage. Dans celui-ci est engagé une soupape 10 réalisée sous la forme d'une aiguille comportant une collerette 10a. Cette soupape sort de la vanne 8 à travers un presse-étoupe 33 afin que son extrémité libre vienne coopérer avec une gâchette 13. Un ressort 18 repousse la soupape vers l'extérieur comme illustré en fig. 1, 10. et 11. La collerette 10a de la soupape 10 est placée sur la longueur de celle-ci de manière qu'en position sortie, c'est-à-dire lorsque la gâchette n'est pas actionnée, le débouché du canal 8a soit situé à l'arrière de cette collerette afin que le gaz pénétrant dans la vanne 8 par le tube 19 puisse s'écouler dans le canal 8a et le tuyau 25 en traversant la partie arrière de l'alésage 8d. On observe qu'un joint torique 11 est disposé entre la collerette et le presse-étoupe 33 afin qu'il n'y ait pas de fuite le long de la soupape lorsqu'elle traverse ledit presse-étoupe et qu'elle se trouve en posiiton avancée. De même un joint torique 12 est associé à l'épaulement constitué par les deux diamètres de l'alésage 8d comme on l'expliquera ci-dessous.The perforations 24a and 24c are supplied with compressed air from the valve 8 by means of pipes 25, respectively 21 (fig. 1). The valve 8 which is fixed below the frame 24 by means of a screw 7 comprises three channels 8a, 8b, 8c (fig. 10) in which the pipes 25 and 21 are fitted respectively, as well as a tube 19 the free end of which constitutes a nozzle to which the compressed gas supply is connected. It is observed that the channel 8c opens into that 8b so that the pipe 21 is supplied directly with gas. A blind stepped bore 8d is formed longitudinally in the valve 8. It is noted that the part with the smallest diameter of the bore 8d is in communication with the channel 8c, while the channel 8a opens into the part with the largest diameter of the said bore . Therein is engaged a valve 10 made in the form of a needle having a flange 10a. This valve leaves the valve 8 through a cable gland 33 so that its free end comes cooperate with a trigger 13. A spring 18 pushes the valve outwards as illustrated in FIG. 1, 10. and 11. The flange 10a of the valve 10 is placed along the length thereof so that in the extended position, that is to say when the trigger is not actuated, the outlet of the channel 8a is located at the rear of this flange so that the gas entering the valve 8 through the tube 19 can flow into the channel 8a and the pipe 25 through the rear part of the bore 8d. It is observed that an O-ring 11 is disposed between the flange and the gland 33 so that there is no leakage along the valve when it passes through said gland and that it is in advanced position. Similarly, an O-ring 12 is associated with the shoulder formed by the two diameters of the bore 8d as will be explained below.

Lorsqu'on actionne la gâchette 13, c'est-à-dire qu'on la fait basculer autour de son axe 32 comme illustré en fig. 11, l'on enfonce la soupape 10 qui se déplace axialement à l'encontre de la réaction du ressort 18 de telle sorte que la collerette 10a de cette soupape vient prendre appui contre le joint 12. On coupe ainsi l'alimentation du tuyau 25 sans contrarier celle du tuyau 21. Le gaz contenu dans l'alésage lc du bloc 1 peut donc s'échapper entre l'alésage du presse-étoupe 33 et la soupape 10 du fait qu'il existe un jeu important entre ces deux éléments et que le joint 11 ne joue plus aucun rôle.When the trigger 13 is actuated, that is to say that it is tilted around its axis 32 as illustrated in FIG. 11, the valve 10 which is moved axially against the reaction of the spring 18 is pressed in so that the flange 10a of this valve comes to bear against the seal 12. The supply of the pipe 25 is thus cut off without opposing that of the pipe 21. The gas contained in the bore lc of block 1 can therefore escape between the bore of the cable gland 33 and the valve 10 because there is a significant clearance between these two elements and that the seal 11 no longer plays any role.

Lorsqu'on désire utiliser le dispositif suivant l'invention l'on prend une cartouche C renfermant du mastic ou autre produit pâteux, on applique sa base contre le piston 30 et l'on exerce sur celui-ci une force à l'encontre de la réaction du ressort 29 (fig.6) de manière à enfoncer ce piston dans le cylindre 28. On peut alors placer le goulot de la cartouche C à l'intérieur de la tête tubulaire 2a du tube 2 (fig. 3) puis on relâche la cartouche. Le ressort 28 applique le corps de celle-ci contre la collerette 2b du tube pour réaliser l'étanchéité entre ce dernier et l'épaulement de la cartouche. En supposant qu'un tuyau d'amenée de gaz comprimé soit branché à l'extrémité du tube 19, suivant la position du tiroir 34 l'air arrive ou non à l'intérieur du cylindre 28. Si ce tiroir est placé dans la position de fig. 8 le gaz arrive dans ledit cylindre, traverse l'espace annulaire compris entre la vis 27 et le trou central du piston 30 ainsi que les trous 30c et 30d pour venir sous le fond mobile de la cartouche en vue d'exercer sur lui une pression. De même le gaz arrivant par le tuyau 25 actionne le piston 4 dont l'extrémité pince le tube 2 de telle sorte que le produit pâteux ne peut pas sortir du tube. Si l'utilisateur appuie sur la gâchette 13 le piston 4 est rappelé vers le bas par le ressort 3 de telle sorte que le tube est libéré et que le produit sort du tube du fait de la pression de l'air sur le fond mobile de la cartouche C. Bien entendu le gaz qui vient d'agir sur le piston est chassé vers l'extérieur en passant dans l'espace annulaire entre le presse-étoupe 33 et la soupape 10.When it is desired to use the device according to the invention, take a cartridge C containing putty or other pasty product, apply its base against the piston 30 and exert on it a force against the reaction of the spring 29 (fig.6) so as to push this piston into the cylinder 28. We can then place the neck of the cartridge C inside the tubular head 2a of the tube 2 (fig. 3) and then releases the cartridge. The spring 28 applies the body thereof against the flange 2b of the tube to seal between the latter and the shoulder of the cartridge. Assuming a compressed gas supply pipe is connected to the end of the tube 19, depending on the position of the drawer 34 the air arrives or not inside the cylinder 28. If this drawer is placed in the position of fig. 8 the gas arrives in said cylinder, passes through the annular space between the screw 27 and the central hole of the piston 30 as well as the holes 30c and 30d to come under the movable bottom of the cartridge in order to exert pressure on it . Similarly, the gas arriving through the pipe 25 actuates the piston 4, the end of which clamps the tube 2 so that the pasty product cannot exit the tube. If the user presses the trigger 13 the piston 4 is returned downwards by the spring 3 so that the tube is released and the product leaves the tube due to the air pressure on the movable bottom of cartridge C. Of course, the gas which has just acted on the piston is expelled towards the outside by passing through the annular space between the cable gland 33 and the valve 10.

On a ainsi réalisé un dispositif qui permet une économie substantielle d'air comprimé, de sorte qu'il peut être alimenté au moyen d'une bouteille de gaz, notamment lorsque l'alimentation en air comprimé est difficile, par exemple lorsque l'utilisateur se trouve sur le toit d'un édifice de grande hauteur.A device has thus been produced which allows a substantial saving of compressed air, so that it can be supplied by means of a gas cylinder, in particular when the supply of compressed air is difficult, for example when the user is on the roof of a tall building.
