Abstract

1. Method of making multiple panes filled with gas, comprising at least two glass sheets (18, 19) connected at their periphery by spacing frame (20) thus defining a space between them, characterised in that a gas other than air is introduced into the space defined by the glass sheets during assembly of the pane, before obturation of the space between the glass sheets.

Description

L'invention concerne d'une manière générale un procédé pour la fabrication de vitrages isolants remplis de gaz et constitués par au moins deux feuilles de verre reliées entre elles par un cadre formant entretoise.The invention relates generally to a process for the manufacture of insulating glazing units filled with gas and constituted by at least two sheets of glass connected together by a frame forming a spacer.

Selon les méthodes usuelles, pour fabriquer un vitrage isolant rempli de gaz, on assemble d'abord le vitrage à l'aide d'un cadre entretoise préalablement percé d'orifices, ou on perce des orifices dans le cadre d'un vitrage déjà assemblé, puis on remplit de gaz l'espace compris entre les feuilles de verre et enfin on obture les orifices du cadre. Celui-ci doit comporter au moins deux orifices, un pour le remplissage par le gaz et un pour la sortie de l'air qu'il faut évacuer. Mais le remplissage en gaz d'un vitrage déjà terminé et l'obturation des orifices du cadre entretoise sont des opérations compliquées et longues, si bien que ce procédé est relativement coûteux et inadapté à la fabrication en grande série de vitrages remplis de gaz.According to the usual methods, to manufacture an insulating glazing filled with gas, the glazing is first assembled using a spacer frame previously pierced with holes, or holes are drilled in the framework of an already assembled glazing , then the space between the glass sheets is filled with gas and finally the holes in the frame are closed. This must have at least two orifices, one for filling with gas and one for the outlet of the air which must be exhausted. However, filling a previously finished glazing with gas and closing the orifices of the spacer frame are complicated and time-consuming operations, so that this process is relatively expensive and unsuitable for mass production of gas-filled glazing.

L'invention vise à permettre la fabrication de vitrages remplis de gaz, de façon continue et beaucoup plus rapide que précédemment.The invention aims to allow the manufacture of glazing filled with gas, continuously and much faster than previously.

Pour cela elle propose un procédé dans lequel on effectue le remplissage en gaz ou en mélange gazeux pendant l'assemblage même du vitrage, avant l'obturation de l'espace compris entre les feuilles de verre.For this it proposes a process in which the filling is carried out with gas or a gaseous mixture during the actual assembly of the glazing, before the space between the glass sheets is closed.

Les éléments du vitrage à assembler sont alors transportés par exemple sur un convoyeur à bande dans une station de montage où l'on peut également amener le gaz ou le mélange gazeux, ces éléments sont alors assemblés et en même temps la charge de gaz est incorporée.The elements of the glazing to be assembled are then transported for example on a belt conveyor in an assembly station where it is also possible to bring the gas or the gaseous mixture, these elements are then assembled and at the same time the gas charge is incorporated .

De préférence une première feuille de verre est d'abord envoyée en position inclinée dans la station de montage, elle est prise par un plateau à dépression formé essentiellement d'un caisson à vide ayant des orifices d'aspiration pour tenir la feuille de verre, puis le plateau se déplace avec la feuille de verre pour permettre l'entrée d'un nouvel élément du vitrage à monter dans la station de montage. Ce deuxième élément se compose de préférence d'une unité préfabriquée formée d'une seconde feuille de verre sur laquelle est fixé un cadre entretoise, la face libre du cadre tournée vers la première feuille de verre maintenue en attente par le plateau à dépression,étant recouverte d'une matière adhésive, par exemple du caoutchouc Butyl. Quand le deuxième élément du vitrage est ainsi dans la station de montage, en face de la première feuille de verre, on envoie du gaz ou le mélange gazeux désiré dans l'espace compris entre les deux feuilles de verre et on chasse l'air.Preferably, a first sheet of glass is first sent in an inclined position to the assembly station, it is taken up by a vacuum plate formed essentially by a vacuum box having suction orifices to hold the sheet of glass, then the tray moves with the glass sheet to allow entry of a new glazing element to be fitted in the assembly station. This second element preferably consists of a prefabricated unit formed of a second sheet of glass on which is fixed a spacer frame, the free face of the frame facing the first sheet of glass held in standby by the vacuum plate, being covered with an adhesive material, for example Butyl rubber. When the second element of the glazing is thus in the assembly station, opposite the first glass sheet, gas or the desired gas mixture is sent into the space between the two glass sheets and the air is expelled.

Dans un mode de réalisation avantageux, la station de montage peut être une presse qui assemble les deux feuilles de verre constitutives du vitrage multiple en y incorporant un gaz.In an advantageous embodiment, the mounting station can be a press which assembles the two glass sheets constituting the multiple glazing by incorporating a gas therein.

Le gaz peut être envoyé dans la presse d'une façon continue ou bien au fur et à mesure des besoins, de haut en bas ou bien de bas en haut. En cas d'amenée continue du gaz, la presse constitue une unité fermée de tous les côtés, afin de réduire au minimum les pertes de gaz.The gas can be sent to the press continuously or as needed, from top to bottom or from bottom to top. In case of continuous gas supply, the press is a closed unit on all sides, in order to minimize gas losses.

L'assemblage des feuilles de verre dans la presse se fait de préférence par application de la première feuille de verre maintenue par le plateau à dépression sur la face libre recouverte de matière adhésive du cadre entretoise fixé sur la seconde feuille de verre.The glass sheets are assembled in the press preferably by applying the first glass sheet held by the vacuum plate on the free face covered with adhesive material of the spacer frame fixed on the second glass sheet.

L'assemblage étant terminé, on ouvre la presse et on évacue le vitrage rempli de gaz qui a ainsi été fabriqué.The assembly being completed, the press is opened and the glazing filled with gas which has thus been produced is removed.

L'invention propose aussi un dispositif pour mettre en oeuvre le procédé de fabrication de vitrages isolants multiples remplis de gaz.The invention also provides a device for implementing the method for manufacturing multiple insulating glazing units filled with gas.

Les Figures 1 et 2 montrent une installation comprenant essentiellement une presse 1, pour la fabrication de vitrages isolants multiples selon un procédé discontinu. La presse 1 se compose d'un premier plateau 2 incliné et en forme de caisson et d'un second plateau 3 basculant par rapport au premier. Les plateaux 2 et 3 se font face et sont reliés entre eux par une articulation pivotante 4 représentée en traits discontinus sur la Figure 2. Les plateaux 2 et 3 sont en outre reliés par au moins un vérin 5 grâce auquel ils peuvent être pressés l'un contre l'autre. Le cas échéant, le plateau mobile 3 peut encore se déplacer latéralement en glissant sur une rampe de guidage 70 (Figure 2) de la ferrure 71 grâce à des vérins supplémentaires 6, de façon à augmenter l'écartement des plateaux 2 et 3 entre eux.Figures 1 and 2 show an installation essentially comprising a press 1, for the manufacture of multiple insulating glazings according to a batch process. The press 1 consists of a first inclined plate 2 in the form of a box and a second plate 3 tilting relative to the first. The plates 2 and 3 face each other and are connected to each other by a pivoting articulation 4 shown in broken lines in FIG. 2. The plates 2 and 3 are also connected by at least one jack 5 by means of which they can be pressed. one against the other. If necessary, the movable plate 3 can still move laterally by sliding on a guide ramp 70 (Figure 2) of the fitting 71 by means of additional jacks 6, so as to increase the spacing of the plates 2 and 3 between them .

Le plateau 2 de la presse a une forme de caisson avec une cavité 74 (Figure 2) munie de renforts 76, et équipée sur sa face arrière d'un raccord 7 pour l'amenée d'air comprimé. L'entrée d'air comprimé dans le raccord 7 est représentée par une flèche 72 sur la Figure 2. La paroi de travail ou paroi avant 8 du plateau 2, disposée vis-à-vis de la paroi arrière 73 du même plateau 2 est munie d'orifices 9 pour le passage de l'air comprimé dans l'entrefer 10 de la presse 1.The plate 2 of the press has a box shape with a cavity 74 (Figure 2) provided with reinforcements 76, and equipped on its rear face with a connector 7 for the supply of compressed air. Compressed air inlet in the fitting 7 is represented by an arrow 72 in FIG. 2. The working wall or front wall 8 of the plate 2, disposed opposite the rear wall 73 of the same plate 2 is provided with holes 9 for the passage of compressed air in the air gap 10 of the press 1.

Lorsqu'on enclenche l'arrivée d'air comprimé, l'air sortant par les orifices 9 forme un coussin d'air entre la paroi de travail avant 8 du plateau 2 et les feuilles de verre 19, 18 en appui contre cette paroi, facilitant ainsi leur glissement lorsqu'elles arrivent et lorsque le vitrage fini est évacué.When the compressed air supply is turned on, the air exiting through the orifices 9 forms an air cushion between the front working wall 8 of the plate 2 and the glass sheets 19, 18 bearing against this wall, thus facilitating their sliding when they arrive and when the finished glazing is removed.

Le plateau 3, disposé verticalement en position de départ de la presse 1 a également de préférence une forme de caisson avec une cavité 12 et des renforts 75. Il est muni d'un raccord d'aspiration 13 reliant la cavité 12 avec un système 14 de production de vide. La paroi de travail ou paroi avant 15 du plateau 3 est munie d'orifices de succion 16 qui permettent de prendre et de maintenir une feuille de verre 18 par succion.The plate 3, arranged vertically in the starting position of the press 1 also preferably has the shape of a box with a cavity 12 and reinforcements 75. It is provided with a suction connection 13 connecting the cavity 12 with a system 14 vacuum production. The working wall or front wall 15 of the plate 3 is provided with suction orifices 16 which make it possible to take and hold a sheet of glass 18 by suction.

Au dessus de l'entrefer 10 de la presse 1, se trouve une rampe 22 de remplissage de gaz, qui peut même pénétrer dans l'entrefer 10. Cette rampe 22 est de préférence un peu plus étroite que l'épaisseur des vitrages isolants à fabriquer afin de permettre la fermeture de la presse, même lorsqu'elle pénètre dans l'entrefer 10. Sur sa face inférieure, cette rampe 22 présente des orifices 23 de sortie du gaz ou du mélange gazeux, amené jusqu'à ladite rampe 22 par une conduite 24. La rampe 22 est subdivisée en une pluralité de chambres 47, 47', 47", 47"', ... par des cloisons 59. Un palpeur 35 destiné à mesurer la longueur des feuilles de verre 18, 19 arrivant dans la presse 1 est disposé à l'entrée de ladite presse, pour commander l'injection de gaz dans la nombre de chambres 47 juste nécessaire dans chaque cas ; on évite ainsi toute consommation non nécessaire de gaz.Above the air gap 10 of the press 1, there is a ramp 22 for filling with gas, which can even penetrate into the air gap 10. This ramp 22 is preferably a little narrower than the thickness of the insulating glazing to be manufacture in order to allow the press to close, even when it enters the air gap 10. On its underside, this ramp 22 has orifices 23 for the outlet of the gas or of the gaseous mixture, brought to said ramp 22 by a pipe 24. The ramp 22 is subdivided into a plurality of chambers 47, 47 ', 47 ", 47"', ... by partitions 59. A probe 35 intended to measure the length of the glass sheets 18, 19 arriving in the press 1 is arranged at the entrance to said press, to control the injection of gas into the number of chambers 47 just necessary in each case; this avoids any unnecessary consumption of gas.

Au-dessus des orifices de sortie 23, la rampe 22 est munie de lèvres d'étanchéité 25, 26 qui obturent la partie supérieure de l'entrefer 10 de la presse. La lèvre d'étanchéité 25 est disposée sur le bas de la paroi latérale de la rampe 22, du côté du plateau 2 ; elle empêche en même temps la rampe 22 de glisser le long de la paroi de travail 8 du plateau 2. La lèvre 26 s'articule de façon élastique sur le haut de la paroi latérale de la rampe 22, du côté du plateau 3, l'extrémité de la lèvre 26 portant sur la paroi de travail 15 du plateau 3.Above the outlet orifices 23, the ramp 22 is provided with sealing lips 25, 26 which seal the upper part of the air gap 10 of the press. The sealing lip 25 is disposed on the bottom of the side wall of the ramp 22, on the side of the plate 2; at the same time it prevents the ramp 22 from sliding along the working wall 8 of the tray 2. The lip 26 is articulated elastically on the top of the side wall of the ramp 22, on the side of the tray 3, l end of the lip 26 bearing on the working wall 15 of the plate 3.

Lors de la fermeture de la presse, la lèvre 26 qui se compose de préférence de plastique indéformable avec un bord extérieur élastique, se déplace vers le haut pour permettre une parfaite fermeture de la presse. La rampe 22 est reliée par la conduite 24 avec une source de gaz 27 (Figure 7). La rampe 22 peut recevoir, avec le gaz excédentaire aspiré et remis en circuit, du gaz ou un mélange gazeux supplémentaire. Mais la source d'approvisionnement en gaz peut également desservir sé- parement chaque chambre 47, 47', 47", etc directement. La position en hauteur de la rampe 22 peut être ajustée grâce à un système de levage 11, agissant sur ses extrémités, par exemple un système de deux chaines verticales. Au-dessous des plateaux 2 et 3 de la presse 1 se trouve une boîte d'aspiration 28 qui obture l'entrefer 10 de la presse vers le bas. La boîte 28 se compose d'un fond 29 au-dessus duquel est placé un couvercle 31 muni de fentes 30. La boite 28 est reliée par une conduite 32 avec un ventilateur d'aspiration 33, qui aspire le gaz excédentaire dans l'entrefer 10 de la presse 1 par l'intermédiaire de la boîte 28.When the press is closed, the lip 26 which is composed preferably of non-deformable plastic with an elastic outer edge, moves upward to allow perfect closing of the press. The ramp 22 is connected by line 24 with a gas source 27 (Figure 7). The ramp 22 can receive, with the excess gas sucked in and put back into circuit, gas or an additional gas mixture. But the gas supply source can also separately supply each chamber 47, 47 ', 47 ", etc. directly. The position in height of the rail 22 can be adjusted by means of a lifting system 11, acting on its ends , for example a system of two vertical chains. Below the plates 2 and 3 of the press 1 is a suction box 28 which closes the air gap 10 of the press down. The box 28 is composed of a bottom 29 above which is placed a cover 31 provided with slots 30. The box 28 is connected by a pipe 32 with a suction fan 33, which sucks the excess gas in the air gap 10 of the press 1 by l through the box 28.

L'étanchéité entre les parois latérales de la boite 28 et les plateaux 2 et 3 de la presse est réalisée. A cet effet, un joint 34 flexible est monté entre la boite 28 et le plateau 3 pour maintenir cette étanchéité lorsque ledit plateau 3 se déplace vers le plateau 2 au moment de la fermeture de la presse. Si on désire, pour améliorer encore l'étanchéité de l'entrefer 10, on peut aussi prévoir sur les côtés entrée et sortie de la presse, des lèvres en caoutchouc (non représentées) qui se chevauchent au moment de la fermeture.The seal between the side walls of the box 28 and the plates 2 and 3 of the press is produced. To this end, a flexible seal 34 is mounted between the box 28 and the plate 3 to maintain this seal when said plate 3 moves towards the plate 2 when the press is closed. If desired, to further improve the sealing of the air gap 10, it is also possible to provide on the inlet and outlet sides of the press, rubber lips (not shown) which overlap at the time of closing.

Devant la presse 1 est installé un plateau 36 de transport et d'appui des feuilles de verre ; ce plateau de transport 36 est légèrement incliné et son inclinaison correspond à l'inclinaison du plateau 2 de la presse 1. Ce plateau 36 a de préférence la forme d'un caisson dont la cavité 37 est en liaison par une conduite 38 avec un ventilateur 39 fournissant de l'air comprimé. Cet air comprimé s'échappe par des orifices 41 de la face de travail ou face avant 40 dudit caisson, qui fait face aux feuilles de verre 18, 19. Un coussin d'air favorisant le glissement des feuilles de verre se forme ainsi entre lesdites feuilles et la paroi avant 40 du plateau 36.In front of the press 1 is installed a plate 36 for transporting and supporting the glass sheets; this transport plate 36 is slightly inclined and its inclination corresponds to the inclination of the plate 2 of the press 1. This plate 36 preferably has the shape of a box whose cavity 37 is connected by a pipe 38 with a fan 39 providing compressed air. This compressed air escapes through orifices 41 of the working face or front face 40 of said box, which faces the glass sheets 18, 19. An air cushion promoting the sliding of the glass sheets is thus formed between said sheets and the front wall 40 of the tray 36.

Avantageusement, le ventilateur 39, par l'intermédiaire de la conduite 69 alimente aussi le plateau 2 de la presse 1.Advantageously, the fan 39, via the line 69 also supplies the plate 2 of the press 1.

Un plateau de transport et d'appui 42, incliné, identique au plateau 36 est également disposé à la sortie de la presse 1.A transport and support plate 42, inclined, identical to the plate 36 is also disposed at the outlet of the press 1.

Pour remplacer le coussin d'air, les plateaux 36 et 42 peuvent être munis de galets usuels tels que 60 comme visualisé sur le plateau 42 de la Figure 1.To replace the air cushion, the plates 36 and 42 can be fitted with usual rollers such as 60 as shown on the plate 42 of Figure 1.

Au-dessous des plateaux d'appui et de transport 36, 42, et également au-dessous du plateau 2 de la presse 1, faisant saillie par rapport aux surfaces de travail de ces différents plateaux 36, 2, 42, sont prévus des rouleaux porteurs 43 montés dans des paliers 44 pour faire défiler les feuilles de verre ou les vitrages multiples fabriqués.Below the support and transport plates 36, 42, and also below the plate 2 of the press 1, projecting from the working surfaces of these different plates 36, 2, 42, there are rollers carriers 43 mounted in bearings 44 for scrolling the sheets of glass or the multiple glazing units manufactured.

A l'extrémité inférieure du plateau 3, au niveau du fond, sont installés les éléments d'appui 45 servant de support inférieur pour les plaques de verre 18. Ces éléments 45 sont montés avec un pas tel que lorsque les plateaux 2 et 3 se rencontrent, ils se trouvent intercalés entre les rouleaux d'appui 4.At the lower end of the plate 3, at the bottom, are installed the support elements 45 serving as a lower support for the glass plates 18. These elements 45 are mounted with a pitch such that when the plates 2 and 3 are meet, they are interposed between the support rollers 4.

Les Figures 3 a 9 illustrent les différentes phases d'une fabrication de vitrages multiples isolants à l'aide de l'installation montrée sur les Figures 1 et 2.Figures 3 to 9 illustrate the different phases of manufacturing multiple insulating glazing units using the installation shown in Figures 1 and 2.

La Figure 3 montre une vue de côté de la presse 1 avec une feuille de verre 18 supportée par le plateau incliné 2, la feuille 18 étant avancée dans la presse jusqu'à une butée. A l'extrémité inférieure du plateau 2, la feuille 18 est supportée et transportée par les rouleaux 43.Figure 3 shows a side view of the press 1 with a glass sheet 18 supported by the inclined plate 2, the sheet 18 being advanced in the press to a stop. At the lower end of the plate 2, the sheet 18 is supported and transported by the rollers 43.

La Figure 4 montre le système fermé. La fermeture de la presse 1 se fait par approche du plateau 3 contre la feuille de verre 18. Une fois la presse fermée, une dépression se produit dans le plateau 3, et la feuille 18 est aspirée sur la paroi de travail avant 15 de ce plateau 3. Le plateau 3, par l'intermédiaire de l'articulation pivotante 4, est alors séparé du plateau 2 (Figure 5). Puis, par l'intermédiaire du plateau d'appui et de transport 36 se trouvant devant la presse, la feuille de verre 19 munie de son cadre entretoise 20, est avancée dans la presse jusqu'à la butée (non représentée) et la rampe 22 de remplissage de gaz s'abaisse (Figure 6). Les faces avant du cadre 20 sont recouvertes d'un adhésif 21, ici, du caoutchouc Butyl, qui du fait de ses bonnes propriétés d'adhérence, convient bien.Figure 4 shows the closed system. The press 1 is closed by approaching the plate 3 against the glass sheet 18. Once the press is closed, a vacuum occurs in the plate 3, and the sheet 18 is sucked on the working wall before 15 of this tray 3. The tray 3, via the pivoting joint 4, is then separated from the tray 2 (Figure 5). Then, by means of the support and transport plate 36 located in front of the press, the glass sheet 19 provided with its spacer frame 20, is advanced into the press up to the stop (not shown) and the ramp 22 gas filling lowers (Figure 6). The front faces of the frame 20 are covered with an adhesive 21, here, butyl rubber, which because of its good adhesion properties, is very suitable.

Aussitôt que la feuille de verre 19 est avancée jusqu'à la butée dans la presse 1 et se trouve ainsi placée exactement vis-à-vis de la feuille de verre 18, le système de transport s'arrête et l'amenée du gaz ou du mélange gazeux 46 par la rampe de remplissage 22 s'enclenche. Le gaz 46 se compose de préférence d'un gaz à hautes propriétés isolantes, par exemple de gaz rare tel que l'hélium, le néon ou l'argon, de gaz carbonique, d'azote, de composés carbone-fluor tels que les fréons, etc... Le gaz excédentaire est aspiré par la conduite 32 installée sur la boîte d'aspiration 28 grâce au ventilateur 33. Ce gaz excédentaire peut être réinjecté dans la conduite 24 puis dans la rampe 22, si on le désire.As soon as the glass sheet 19 is advanced to the stop in the press 1 and is thus placed exactly opposite the glass sheet 18, the transport system stops and the supply of gas or of the gas mixture 46 by the filling ramp 22 engages. The gas 46 preferably consists of a gas with high insulating properties, for example a rare gas such as helium, neon or argon, carbon dioxide, nitrogen, carbon-fluorine compounds such as freons, etc ... The excess gas is sucked through line 32 installed on the suction box 28 through the fan 33. This excess gas can be reinjected into line 24 and then into the manifold 22, if desired.

Aussitôt que l'entrefer 10 de la presse 1 est rempli de gaz 46 (Figure 7), le plateau 3 avec la première feuille de verre 18 est rapproché du cadre entretoise 20 collé sur la seconde feuille de verre 19 elle-même en appui sur le plateau 2, et une pression P est appliquée grâce aux vérins 5 et 6 (Figure 8). Les feuilles de verre étant comprimées sur le cadre entretoise 20 recouvert d'adhésif, et en même temps la cavité entre les feuilles de verre remplie de gaz étant obturée, le vitrage multiple isolant rempli de gaz (Figure 10) se trouve fabriqué. Après cela, la presse s'ouvre par recul du plateau 2 et le vitrage fabriqué sort de l'entrefer de la presse en roulant sur les rouleaux 43 (Figure 9). Pendant le pressage P, l'arrivée d'air comprimé au plateau 2 est stoppée par la soupape 77 ; pendant le pressage on peut aussi interrompre la dépression appliquée au plateau 3 en agissant sur la soupape 78.As soon as the air gap 10 of the press 1 is filled with gas 46 (Figure 7), the plate 3 with the first glass sheet 18 is brought closer to the spacer frame 20 glued to the second glass sheet 19 itself resting on the plate 2, and a pressure P is applied by means of the jacks 5 and 6 (Figure 8). The glass sheets being compressed on the spacer frame 20 covered with adhesive, and at the same time the cavity between the glass sheets filled with gas being closed, the multiple insulating glazing filled with gas (Figure 10) is manufactured. After that, the press opens by retreating from the plate 2 and the glazing produced leaves the air gap of the press by rolling on the rollers 43 (Figure 9). During pressing P, the supply of compressed air to the plate 2 is stopped by the valve 77; during pressing, the vacuum applied to the plate 3 can also be interrupted by acting on the valve 78.

Les Figures 11 et 12 représentent une variante d'installation pour la fabrication de vitrages multiples isolants remplis de gaz. Dans cette variante, le plateau 3 de la presse 1 ne bascule pas, mais se déplace parallèlement à lui-même et au plateau 2 en glissant sur des rampes de guidage 70. Ces rampes de guidage 70 peuvent être constituées par les bords supérieurs de la boite d'aspiration 28. Le plateau 3 se déplace, par l'intermédiaire d'au moins un vérin 6 à chacune de ses extrémités, vers le plateau 2, ou s'écarte de ce dernier lorsque la presse 1 doit s'ouvrir. Les vérins 6 sont reliés d'un côté à la paroi extérieure 79 du plateau 3 et de l'autre côté au bâti du dispositif par une oreille 80 fixée sur la boîte d'aspiration 28. Les vérins 6 sont de préférence commandés pneumatiquement. L'avantage du dispositif selon la Figure 12 réside dans le fait que l'entrefer 10 entre les plateaux 2 et 3 est plus petit, ce qui produit de plus faibles pertes de gaz au remplissage du vitrage multiple, car le volume de gaz dans la presse ouverte est plus petit.Figures 11 and 12 show an installation variant for the production of multiple insulating glazing units filled with gas. In this variant, the plate 3 of the press 1 does not tilt, but moves parallel to itself and to the plate 2 by sliding on guide rails 70. These guide rails 70 can be formed by the upper edges of the suction box 28. The plate 3 moves, via at least one cylinder 6 at each of its ends, towards the plate 2, or moves away from the latter when the press 1 must open. The jacks 6 are connected on one side to the outer wall 79 of the plate 3 and on the other side to the frame of the device by a lug 80 fixed to the suction box 28. The jacks 6 are preferably controlled pneumatically. The advantage of the device according to Figure 12 lies in the fact that the air gap 10 between the plates 2 and 3 is smaller, which produces lower gas losses when filling the multiple glazing, because the volume of gas in the open press is smaller.

Les Figures 13 à 19 illustrent la fabrication d'un vitrage multiple rempli de gaz avec le dispositif des Figures 11 et 12. La Figure 13 montre la presse 1 de la Figure 11, vue de côté avec la feuille de verre 18 en place. Dans la Figure 14, la presse est fermée et le plateau 3 qui ici aussi a de préférence la forme d'un caisson subit une dépression qui aspire la feuille 18 sur ce plateau. Lors de l'ouverture de la presse (Figure 15), la feuille 18 est maintenue contre le plateau 3 par effet de succion et repose sur les éléments d'appui 45. Après l'ouverture de la presse, la deuxième feuille de verre 19 entre dans la presse, puis la rampe de remplissage de gaz 22 s'abaisse dans l'entrefer 10 (Figure 16), et ce jusqu'à approcher le bord supérieur de la feuille 19. L'étanchéité par rapport au plateau 2 est obtenue par le joint 25. Sur cette feuille 19, un cadre entretoise 20 est collé par un adhésif 21. Dès que la feuille 19 se trouve vis-à-vis de la feuille 18, le soufflage d'air comprimé dans le plateau 2 est stoppé et l'amenée du gaz 46 par la rampe 22 s'enclenche. Puis le plateau 3 avec la feuille 18 maintenue sur la surface de sa paroi de travail avant 15 est pressé contre le cadre entretoise 20 par les vérins 5 et 6 (Figure 18). La compression des feuilles de verre et de l'entretoise 20 a pour effet d'obturer d'une façon étanche la cavité entre les feuilles 18 et 19. Après la fin de l'opération de pressage, la presse s'ouvre et le vitrage fini est évacué de la presse (Figure 19). Pendant l'ouverture de la presse 1, la rampe de remplissage de gaz 22 remonte pour sortir de l'entrefer 10. Dans ce dispositif également, le gaz 46 excédentaire aspiré par la conduite 32 peut être renvoyé dans la rampe 22 par l'intermédiaire d'un ventilateur d'aspiration-compression 81 et de la conduite 24. La rampe 22 n'est ici représentée qu'avec une seule chambre 47 avec un flexible d'amenée 24 mais il est évident qu'une rampe à plusieurs chambres, par exemple 47' à 47", 47"' etc, est également possible.Figures 13 to 19 illustrate the manufacture of a multiple glazing unit filled with gas with the device of Figures 11 and 12. Figure 13 shows the press 1 of Figure 11, side view with the glass sheet 18 in place. In Figure 14, the press is closed and the plate 3 which here also preferably has the shape of a box undergoes a depression which sucks the sheet 18 on this tray. When the press is opened (Figure 15), the sheet 18 is held against the plate 3 by suction effect and rests on the support elements 45. After the press has been opened, the second glass sheet 19 enters the press, then the gas filling ramp 22 lowers in the air gap 10 (Figure 16), until it approaches the upper edge of the sheet 19. The seal relative to the plate 2 is obtained by the seal 25. On this sheet 19, a spacer frame 20 is glued with an adhesive 21. As soon as the sheet 19 is opposite the sheet 18, the blowing of compressed air into the plate 2 is stopped and the supply of gas 46 by the rail 22 is engaged. Then the plate 3 with the sheet 18 held on the surface of its front working wall 15 is pressed against the spacer frame 20 by the jacks 5 and 6 (Figure 18). The compression of the glass sheets and of the spacer 20 has the effect of sealingly closing the cavity between the sheets 18 and 19. After the end of the pressing operation, the press opens and the glazing finished is removed from the press (Figure 19). During the opening of the press 1, the gas filling ramp 22 rises to exit the air gap 10. In this device also, the excess gas 46 sucked in through line 32 can be returned to the ramp 22 via a suction-compression fan 81 and the pipe 24. The ramp 22 is here shown only with a single chamber 47 with a supply hose 24 but it is obvious that a ramp with several chambers, for example 47 'to 47 ", 47"' etc, is also possible.

Les Figures 20 et 21 montrent une autre variante du dispositif pour la fabrication de vitrages multiples isolants remplis de gaz. La presse 1 est dans ce cas entourée d'un carter 48 et la rampe 50 de remplissage de gaz est de préférence montée fixe dans le couvercle 49 du carter 48. La rampe 50 peut toutefois traverser le couvercle 49, l'orifice de passage de ladite rampe étant rendu étanche par exemple par un joint en caoutchouc. La rampe 50 est reliée à la source de gaz 27 par une conduite 51 et une conduite 52 munie d'une soupape 53. La conduite 51 reçoit aussi la conduite 32, issue de la boîte d'aspiration 28, et munie d'une soupape 54 et d'un système de refoulement 33.Figures 20 and 21 show another variant of the device for manufacturing multiple insulating glazing units filled with gas. The press 1 is in this case surrounded by a casing 48 and the gas filling rail 50 is preferably mounted fixed in the cover 49 of the housing 48. The rail 50 can however pass through the cover 49, the orifice for passage of said ramp being sealed, for example by a rubber seal. The manifold 50 is connected to the gas source 27 by a pipe 51 and a pipe 52 provided with a valve 53. The pipe 51 also receives the pipe 32, coming from the suction box 28, and provided with a valve 54 and a delivery system 33.

De cette façon, le gaz 46 excédentaire aspiré dans la boîte \ 28 est renvoyé dans la rampe 50. Cette rampe, dans le présent dispositif, est de préférence en une seule partie et par ses orifices 23 situés sur sa face inférieure le gaz s'écoule de préférence continuellement dans l'entrefer 10 entre les plateaux 2 et 3 de la presse. Il se forme ainsi une atmosphère de gaz entre ces plateaux. Ici aussi le plateau 3 de la presse 1 peut être mis en dépression. Le plateau 2, par contre, par l'intermédiaire du raccord 7, reçoit également le gaz de remplissage en surpression pour la formation d'un coussin gazeux entre lui-même et la plaque 18. Ce coussin gazeux a la même fonction que le coussin d'air des dispositifs précédents.In this way, the excess gas 46 sucked into the box \ 28 is returned to the rail 50. This rail, in the present device, is preferably in a single part and through its orifices 23 located on its underside the gas s' preferably flows continuously into the air gap 10 between the plates 2 and 3 of the press. It is thus forms a gas atmosphere between these plates. Here also the plate 3 of the press 1 can be put under vacuum. The plate 2, on the other hand, via the connector 7, also receives the overpressure filling gas for the formation of a gas cushion between itself and the plate 18. This gas cushion has the same function as the cushion of the previous devices.

L'avant de la presse 1 est obturé par un volet 55 coulissant horizontalement ou verticalement, en une seule partie, ou en plusieurs parties.The front of the press 1 is closed by a flap 55 sliding horizontally or vertically, in a single part, or in several parts.

La sortie de la presse 1 possède de préférence des lèvres élastiques 56 dont les bords se chevauchent de façon à permettre la sortie du vitrage fabriqué sans mécanisme mobile et commande d'ouverture spéciale synchronisée avec le mouvement dudit vitrage.The output of the press 1 preferably has elastic lips 56 whose edges overlap so as to allow the output of the glazing produced without a mobile mechanism and special opening control synchronized with the movement of said glazing.

Le carter renfermant la presse 1, fermé latéralement par le volet 55 d'un'côté et les lèvres 56 de l'autre côté est de préférence précédé d'un sas 57 muni d'un volet mobile d'entrée 58, sas à l'intérieur duquel se situe le plateau d'appui et de transport 36.The casing containing the press 1, closed laterally by the flap 55 on one side and the lips 56 on the other side is preferably preceded by an airlock 57 provided with a movable inlet flap 58, airlock at the inside of which is located the support and transport plate 36.

Des palpeurs 62 ou des dispositifs équivalents de repérage de la présence du vitrage sont prévus, devant le sas 57 et à l'intérieur dudit sas pour commander l'ouverture et la fermeture des volets 58 et 55. Ce sas préliminaire 57 sert à réduire les pertes de gaz qui se produisent inévitablement du fait de l'ouverture du volet 55. A la sortie du carter 48, on peut utiliser le système de lèvres élastiques 56 étant donné que le vitrage multiple est terminé et qu'il ne présente plus de surfaces collantes.Probes 62 or equivalent devices for identifying the presence of the glazing are provided, in front of the airlock 57 and inside said airlock to control the opening and closing of the flaps 58 and 55. This preliminary airlock 57 serves to reduce the gas losses which inevitably occur due to the opening of the flap 55. At the outlet of the casing 48, it is possible to use the elastic lip system 56 since the multiple glazing is finished and that it no longer has any surfaces sticky.

Le sens d'écoulement du gaz ou du mélange gazeux de haut en bas selon les Figures 1, 11 et 20, peut en cas de besoin être inversé.The direction of flow of the gas or the gas mixture from top to bottom according to FIGS. 1, 11 and 20 can, if necessary, be reversed.

Le procédé de fabrication décrit ci-dessus permet le remplissage par un gaz de vitrages multiples de n'importe quelles dimensions, sans qu'il soit nécessaire de pratiquer le moindre réglage pour passer d'une dimension à une autre.The manufacturing process described above allows filling with multiple glazing gas of any size, without the need to make any adjustment to move from one dimension to another.
