Description

La présente invention se rapporte à un outillage de retrait d'un joint d'une gorge, ainsi qu'à un procédé de retrait d'un joint d'une gorge de réception d'un joint par cet outillage.The present invention relates to a tool for removing a seal from a groove, as well as to a method for removing a seal from a groove for receiving a seal by this tool.

On utilise beaucoup, dans le domaine des non-tissés, le liage par jet d'eau qui est une consolidation de nappe fibreuse par liage par jet d'eau. On a besoin, à cet effet, d'un injecteur qui distribue uniformément l'eau sous pression, allant de 1 à 400 bar, sur toute la longueur du voile formé par la machine. On connaît essentiellement une distribution par l'intermédiaire d'un forage, puis de trous de distribution, suivis d'une chambre de répartition, et une distribution par un forage, suivie d'une fente. Le dispositif de projection de jet d'eau, dénommé aussi injecteur, comprend notamment un corps et un mors résistant à la pression et délimitant une chambre intérieure ayant une entrée. La chambre intérieure communique avec interposition d'une plaque perforée avec une fente de sortie débouchant à l'extérieur du mors ou de l'injecteur. Une gorge sans fin est usinée dans le mors, en entourant la fente de sortie. Cette gorge à la forme d'une piste d'athlétisme, en ayant deux parties opposées délimitées chacune par un bord intérieur et un bord extérieur et deux parties courbes d'extrémité. Un joint torique est placé dans cette gorge afin d'assurer le maintien et l'étanchéité de la plaque perforée. L'objectif est que l'eau sous pression ne puisse sortir de l'injecteur que par les trous (buses) de la plaque perforée.In the field of nonwovens, water-jet bonding, which is a consolidation of the fibrous web by water-jet bonding, is widely used. For this purpose, an injector is needed which uniformly distributes the water under pressure, ranging from 1 to 400 bar, over the entire length of the web formed by the machine. Essentially, a distribution via a borehole, then distribution holes, followed by a distribution chamber, and a distribution via a borehole, followed by a slot, is known. The water jet projection device, also referred to as an injector, comprises in particular a body and a pressure-resistant jaw and delimiting an interior chamber having an inlet. The inner chamber communicates with the interposition of a perforated plate with an outlet slot opening outside the jaw or the injector. An endless groove is machined into the bit, surrounding the exit slot. This groove in the form of an athletics track, having two opposite parts each delimited by an inner edge and an outer edge and two curved end parts. An O-ring is placed in this groove to maintain and seal the perforated plate. The aim is that the pressurized water can only exit the injector through the holes (nozzles) of the perforated plate.

L'invention vise un outillage permettant d'enlever le joint proprement, sans le casser, sans prendre le risque de laisser des résidus dans le mors et sans ouvrir la lumière arrière du mors, particulièrement difficile d'accès sur des machines industrielles.The invention relates to a tool making it possible to remove the seal cleanly, without breaking it, without taking the risk of leaving residues in the jaw and without opening the rear light of the jaw, which is particularly difficult to access on industrial machines.

L'invention a pour objet un outillage de retrait d'un joint en élastomère sans fin d'un injecteur, caractérisé en ce qu'il comprend un embout d'un seul tenant ,de symétrie par rapport à un plan médian longitudinal et ayant une face inférieure plane, de laquelle sont issus deux patins longitudinaux ayant chacun une extrémité avant, et une face supérieure, sur laquelle sont usinées, successivement de l'avant vers l'arrière :

  • à l'avant, deux facettes inclinées par rapport à la face inférieure en allant jusqu'aux extrémités des patins en y formant des becs de raclage;
  • une rampe en T, du bord transversal inférieur duquel sont issues les deux facettes et dont le bord transversal supérieur le plus haut, moins large que le bord transversal inférieur, est commun au bord transversal avant d'une barre centrale longitudinale ; et
  • la barre centrale de moindre largeur que la largeur de la face inférieure.
The subject of the invention is a tool for removing an endless elastomer seal from an injector, characterized in that it comprises an end piece in one piece, of symmetry with respect to a longitudinal median plane and having a flat underside, from which come two longitudinal runners each having a front end, and an upper side, on which are machined, successively from the front to the rear:
  • at the front, two facets inclined with respect to the lower face, going as far as the ends of the runners, forming scraping tips there;
  • a T-shaped ramp, from the lower transverse edge from which the two facets originate and whose uppermost transverse edge, narrower than the lower transverse edge, is common to the front transverse edge of a central longitudinal bar; and
  • the central bar of lesser width than the width of the lower face.

En faisant pénétrer l'embout dans la chambre de l'injecteur, les becs raclent les gorges, dans lesquelles se trouvent les brins rectilignes du joint et les soulèvent. Lorsque l'embout arrive jusqu'au brin curviligne le plus loin de la lumière par laquelle l'embout a été introduit, ce brin curviligne se soulève aussi. En retirant l'embout, le joint tout entier est retiré.By making the tip penetrate into the chamber of the injector, the nozzles scrape the grooves, in which the rectilinear strands of the joint are located and lift them. When the tip reaches the curvilinear strand farthest from the lumen through which the tip was introduced, this curvilinear strand also rises. By removing the end cap, the entire gasket is removed.

Il l'est d'autant mieux que, de préférence, l'embout comprend de part et d'autre de la barre centrale longitudinale, deux barrettes longitudinales, dans l'alignement longitudinal des facettes, de moindre épaisseur que la barre centrale, issues du bord transversal supérieur le moins haut de la rampe et se prolongeant vers l'arrière au-delà d'elle jusqu'à des bords arrières en arc-de-cercle, en définissant entre elles et avec le bord arrière de la barre centrale et la face supérieure un logement de réception d'une pièce de maintien d'un plat de rallonge distinct, à bord circulaire, s'adaptant aux bords arrière en arc-de-cercle, le plat de rallonge ayant l'épaisseur des barrettes et la somme de l'épaisseur du plat de rallonge et de l'épaisseur de la pièce de maintien étant égale à l'épaisseur de la barre centrale. Le plat de rallonge est plus long que l'embout. Il peut avoir une longueur de 1 000 à 8 000 mm, tandis que l'embout peut avoir une longueur de 70 à 300 mm. La longueur s'entend parallèlement au plan médian de l'embout. La largeur s'entend transversalement à la longueur.It is all the better that, preferably, the end piece comprises on either side of the longitudinal central bar, two longitudinal bars, in the longitudinal alignment of the facets, of less thickness than the central bar, from from the lower upper transverse edge of the ramp and extending rearwards beyond it to arcuate rear edges, defining therebetween and with the rear edge of the central bar and the upper face a housing for receiving a part for holding a separate extension plate, with a circular edge, adapting to the rear edges in an arc of a circle, the extension plate having the thickness of the bars and the sum of the thickness of the extension plate and the thickness of the retaining piece being equal to the thickness of the central bar. The extension plate is longer than the end piece. It can be 1000-8000mm long, while the end cap can be 70-300mm long. The length is parallel to the median plane of the end piece. The width is understood transversely to the length.

L'angle de la rampe et/ou des facettes avec la face inférieure de l'embout est compris entre 5 et 30°, de préférence entre 10 et 20° et mieux est de 15°. De préférence, l'angle de la rampe avec la face inférieure est égal à celui des facettes avec la face inférieure.The angle of the ramp and/or of the facets with the lower face of the endpiece is between 5 and 30°, preferably between 10 and 20° and better still is 15°. Preferably, the angle of the ramp with the lower face is equal to that of the facets with the lower face.

On peut prévoir un trou de centrage dans l'embout et qu'un doigt de la pièce de maintien pénètre dans ce trou en passant par une ouverture du plat de rallonge superposée au trou.It is possible to provide a centering hole in the endpiece and a finger of the holding part to enter this hole by passing through an opening of the extension plate superimposed on the hole.

L'invention vise également l'utilisation d'un outillage suivant l'invention pour le retrait d'un joint de la chambre d'un injecteur, la section transversale hors-tout de l'outillage étant juste inférieure à la section transversale de la chambre.The invention also relates to the use of a tool according to the invention for removing a seal from the chamber of an injector, the overall cross section of the tool being just lower than the cross section of the bedroom.

L'invention vise enfin un procédé de retrait d'un joint de la chambre d'un injecteur, dans lequel on introduit l'outillage suivant l'invention dans la chambre de l'injecteur patins côté mors jusqu'à libérer le tronçon curviligne le plus proche du joint. On tire sur ce brin curviligne et on le tient à la main ou, de préférence, on l'accroche à un crochet ou bouton issu de l'injecteur du côté de l'opérateur, on introduit ensuite davantage l'outillage suivant l'invention patins côté mors jusqu'à ce qu'il vienne en butée côté transmission, en sorte que le joint est libéré et on retire l'ensemble de l'outillage et du joint.The invention finally relates to a process for removing a seal from the chamber of an injector, in which the tool according to the invention is introduced into the chamber of the injector on the jaw side until the curvilinear section is freed. closer to the joint. This curvilinear strand is pulled and it is held by hand or, preferably, it is hung on a hook or button from the injector on the side of the operator, the tool according to the invention is then further introduced. pads on the jaw side until it comes into abutment on the transmission side, so that the seal is released and all of the tools and the seal are removed.

In the accompanying drawings given solely by way of example:
  • the figure 1 is a sectional view of an injector, for which the removal tool according to the invention is used;
  • the figure 2 is a partial perspective view with removal of the upper part of the body of the end of the injector chamber;
  • the picture 3 is an exploded perspective view of a tool according to the invention;
  • the figure 4 is a perspective view from below of the end piece of the tool according to the invention; and
  • the figure 5 is a perspective view from above.

L'injecteur représenté à la figure 1 comprend un corps 1 supérieur, auquel est vissé un mors 2, l'ensemble constituant l'injecteur en acier inoxydable qui résiste à la pression. Le corps et le mors délimitent une chambre 3 intérieure ayant une entrée et communiquant par une fente 4, avec interposition d'une plaque perforée (non représentée au dessin), avec une fente 5 de sortie débouchant à l'extérieur du mors ou de l'injecteur.The injector shown in figure 1 comprises an upper body 1, to which is screwed a jaw 2, the assembly constituting the stainless steel injector which resists the pressure. The body and the jaw delimit an interior chamber 3 having an entrance and communicating via a slot 4, with the interposition of a perforated plate (not shown in the drawing), with an outlet slot 5 opening outside the jaw or the jaw. 'injector.

Une gorge 6 sans fin est usinée dans le mors 2, en entourant la fente 5 de sortie. Dans cette gorge doit être monté un joint 7 torique élastique en matière élastomère. Comme le montre la figure 2, la gorge 6 a deux parties 8, 9 opposées rectilignes, délimitées chacune par un bord 10, 11 intérieur et par un bord 12, 13 extérieur, et deux parties (une seule est représentée) courbées 14 d'extrémité, qui ne sont toutes deux délimitées que par un bord intérieur. Dans ces parties courbées d'extrémité, la gorge est dite ouverte. Une partie d'un joint qui tombe dans la plage ainsi délimitée aura toute facilité à venir s'appliquer sur le bord 14 par retour élastique, si le joint est au préalable étiré.An endless groove 6 is machined in the jaws 2, surrounding the outlet slot 5. In this groove must be mounted an elastic O-ring 7 made of material elastomer. As shown in figure 2 , the groove 6 has two rectilinear opposite parts 8, 9, each delimited by an inner edge 10, 11 and by an outer edge 12, 13, and two curved end parts (only one is shown) 14, which are not all two delimited only by an inner edge. In these curved end parts, the groove is said to be open. A part of a seal which falls within the range thus delimited will easily come to rest on the edge 14 by elastic return, if the seal is stretched beforehand.

On voit à la figure 2 qu'une seconde lumière 15 est ménagée sur une seconde face frontale du mors 2. Elle a des dimensions telles qu'un outillage de mise en place d'un joint dans la gorge peut y passer. Une première lumière 15 de même dimension se trouve à l'autre bout du tunnel 16 délimité par ses lumières 15 par une face 17 du corps 1 et par la face 18 inférieure; dans laquelle est usinée la gorge 6.We see at the figure 2 that a second slot 15 is provided on a second end face of the jaw 2. It has dimensions such that a tool for fitting a seal in the groove can pass through it. A first slot 15 of the same size is located at the other end of the tunnel 16 delimited by its slots 15 by a face 17 of the body 1 and by the lower face 18; in which groove 6 is machined.

La section transversale des lumières 15 et donc celle du tunnel est juste supérieure au rectangle délimité par les dimensions hors tout de l'outillage de mise en place.The cross section of the slots 15 and therefore that of the tunnel is just greater than the rectangle delimited by the overall dimensions of the installation tool.

L'outillage suivant l'invention comprend un embout d'un seul tenant de symétrie par rapport à un plan médian longitudinal, ayant une face 20 inférieure plane, de laquelle sont issus deux patins 21 longitudinaux ayant chacun une extrémité avant, et une face supérieure. La face 20 est inférieure à la figure, mais lorsque l'outillage est destiné à être utilisé dans un injecteur incliné ou orienté différemment, elle peut se trouver au-dessus de l'autre face. Dans le présent mémoire, on désigne les deux faces par inférieure et supérieure simplement pour faciliter l'exposé.The tool according to the invention comprises an endpiece in one piece of symmetry with respect to a longitudinal median plane, having a flat lower face 20, from which two longitudinal pads 21 come, each having a front end, and an upper face . Face 20 is lower than the figure, but when the tooling is intended to be used in an inclined or differently oriented injector, it may be above the other face. In this specification, the two faces are referred to as lower and upper simply for ease of discussion.

Sur la face supérieure opposée à la face 20, sont usinées successivement de l'avant vers l'arrière, à l'avant, deux facettes 22 inclinées d'un angle de 15°, par rapport à la face 20 inférieure, en allant jusqu'aux extrémités des patins 21 en y formant ainsi des becs de raclage.On the upper face opposite the face 20, are machined successively from front to rear, at the front, two facets 22 inclined at an angle of 15°, relative to the lower face 20, going up to 'at the ends of the pads 21 thereby forming therein scraping spouts.

Une rampe 23 en T, qui est inclinée de 15° par rapport à la face inférieure et du bord transversal inférieur duquel sont issues les deux facettes 22 et dont le bord transversal le plus haut, moins large que le bord transversal inférieur, est commun au bord avant d'une barre 24 centrale de moindre largeur que la largeur de la face 20 inférieure. De part et d'autre de la barre 24 centrale, s'étendent deux barrettes 25 longitudinales, de moindre épaisseur que la barre 24 centrale, dans l'alignement longitudinal des facettes 22 et se prolongeant vers l'arrière au-delà de la barre 24 centrale, en définissant entre elles et avec le bord arrière de la barre 24 centrale et la face supérieure un logement de réception d'une pièce 26 de maintien d'un plat 27 de rallonge distinct à bord circulaire, s'adaptant au bord arrière en arc-de-cercle. Le plat 27 de rallonge a l'épaisseur des barrettes 25 et la somme de l'épaisseur du plat 27 de rallonge et de l'épaisseur de la pièce 26 de maintien est égale à l'épaisseur de la barre 24 centrale. Il a une longueur de 6 m, alors que l'embout a une longueur de 1 m.A T-shaped ramp 23, which is inclined by 15° with respect to the lower face and the lower transverse edge from which the two facets 22 originate and whose highest transverse edge, narrower than the lower transverse edge, is common to the front edge of a central bar 24 of less width than the width of the lower face 20. On either side of the central bar 24 extend two strips 25 longitudinal, of less thickness than the central bar 24, in the longitudinal alignment of the facets 22 and extending rearwardly beyond the central bar 24, defining between them and with the rear edge of the central bar 24 and the upper face a housing for receiving a part 26 for holding a separate flat extension 27 with a circular edge, fitting to the rear edge in an arc of a circle. The extension plate 27 has the thickness of the strips 25 and the sum of the thickness of the extension plate 27 and the thickness of the retaining part 26 is equal to the thickness of the central bar 24. It has a length of 6 m, while the end piece has a length of 1 m.

Un trou 28 central est prévu dans l'embout. Un doigt 29 de la pièce 26 de maintien pénètre par ce trou dans l'embout. Le plat 27 de rallonge est vissé de manière amovible par deux vis 30 à tête fraisée (vis Fhc), qui ne dépasse de la face 20 inférieure, et par deux écrous 31 à l'embout, et maintenu par la pièce 26 de maintien sur le reste de l'outillage.A central hole 28 is provided in the tip. A finger 29 of the holding part 26 penetrates through this hole in the endpiece. The flat 27 extension is screwed in a removable manner by two screws 30 with countersunk head (screw Fhc), which does not protrude from the lower face 20, and by two nuts 31 at the tip, and held by the part 26 for holding on the rest of the tools.

Le plat 27 de rallonge est constitué d'un feuillard en acier inoxydable, tandis que le reste des pièces est en une matière plastique rigide. Le plat 27 de rallonge est enroulable.The extension dish 27 is made of a stainless steel strip, while the rest of the parts are made of a rigid plastic material.
