Description

La présente invention se rapporte à un outillage de mise en place d'un joint dans une gorge. Elle se rapporte aussi à un procédé de mise en place d'un joint dans une gorge de réception d'un joint, dans lequel on utilise un outillage de mise en place du joint.The present invention relates to a tool for installing a seal in a groove. It also relates to a method for fitting a seal in a groove for receiving a seal, in which a tool for fitting the seal is used.

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. 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, ayant deux brins rectilignes et deux brins curvilignes, 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.Water-jet bonding, which is a consolidation of the fibrous web by water-jet bonding, is widely used in the field of nonwovens. 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. 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, having two rectilinear strands and two curvilinear strands, is placed in this groove in order to ensure the maintenance and sealing of the perforated plate. The aim is that the pressurized water can only exit the injector through the holes (nozzles) of the perforated plate.

L'outillage de mise en place d'un joint torique en élastomère décrit au brevet français 2 902 035 s'est imposé dans la technique. L'invention vise à perfectionner la mise en place d'un joint en élastomère sans fin dans un injecteur.The tool for installing an elastomer O-ring described in the patent French 2,902,035 established itself in technology. The invention aims to improve the fitting of an endless elastomer seal in an injector.

On utilise suivant l'invention un outillage ou un ensemble de cet outillage et du joint qu'il sert à poser, qui comprend une roue tournant autour d'un axe et ayant un seul crochet. Le crochet fait saillie vers l'extérieur de la jante de la roue et s'étend seulement dans le plan médian de la jante perpendiculaire à l'axe. Il est de symétrie par rapport à ce plan. Ses deux faces latérales sont respectivement à une même distance des faces latérales ou joues de la roue, dans la direction de l'axe. Le crochet a une face concave et une face convexe opposée à la face concave. Le joint à poser est accroché au crochet et est enroulé autour de la jante en pouvant ainsi se dérouler en étant parfaitement guidé sans torsion. En outre, cela permet d'emmagasiner le joint à l'abri des poussières et autres salissures par contact avec le sol, comme c'est le cas pour des joints d'une longueur de chaque brin rectiligne de 3 à 4 mètres. Pour que le joint soit encore mieux équilibré sur la roue, il vaut mieux que la face concave du crochet en contact avec le joint ait le même rayon de courbure que le tore du joint.According to the invention, a tool or a set of this tool and of the seal that it is used to install is used, which comprises a wheel rotating around an axis and having a single hook. The hook projects outward from the rim of the wheel and extends only in the median plane of the rim perpendicular to the axis. It is symmetrical with respect to this plane. Its two side faces are respectively at the same distance from the side faces or flanges of the wheel, in the direction of the axis. The hook has a concave face and a convex face opposite the concave face. The seal to be installed is attached to the hook and is wrapped around the rim, thus being able to unroll being perfectly guided without torsion. In addition, this makes it possible to store the seal protected from dust and other dirt by contact with the ground, as is the case for seals with a length of each rectilinear strand of 3 to 4 meters. For the seal to be even better balanced on the wheel, it is better that the concave face of the hook in contact with the seal has the same radius of curvature as the torus of the seal.

Pour bien guider l'entrée du joint par une lumière de la chambre d'un injecteur, l'outillage a, suivant un mode de réalisation qui peut être combiné à ce qui précède mais qui constitue également une invention indépendamment de celui-ci, une chape fixée à l'axe, dont l'âme définit un tunnel rectiligne et au plancher duquel est fixé un plat d'accompagnement, qui dépasse du tunnel par la sortie de celui-ci. Le tunnel a de préférence une longueur de 50 à 200 mm.In order to properly guide the entry of the joint by a hole in the chamber of an injector, the tooling has, according to an embodiment which can be combined with the foregoing but which also constitutes an invention independently of the latter, a yoke fixed to the axle, whose core defines a rectilinear tunnel and to the floor of which is fixed a side plate, which protrudes from the tunnel through the outlet thereof. The tunnel preferably has a length of 50 to 200 mm.

Pour mieux guider le joint pendant son enroulement, il est prévu deux encoches, qui sont parallèles à la direction longitudinale du tunnel sur la face extérieure de l'âme, qui débouchent sur la face frontale d'entrée du tunnel et qui sont symétriques l'une de l'autre par rapport au plan médian. Cela permet de bien paralléliser les deux brins parallèles du joint à l'enroulement.To better guide the seal during its winding, two notches are provided, which are parallel to the longitudinal direction of the tunnel on the outer face of the core, which open onto the front entrance face of the tunnel and which are symmetrical one from the other with respect to the median plane. This makes it possible to properly parallelize the two parallel strands from the joint to the winding.

De préférence, il est prévu deux rainures parallèles à la direction longitudinale du tunnel sur les faces latérales intérieures du tunnel, les deux rainures étant symétriques par rapport au plan médian de la jante perpendiculaire à l'axe. Ces deux rainures sont destinées à guider un plat ou lame de rallonge, dont les deux bords longitudinaux sont insérés dans les rainures depuis l'entrée du tunnel.Preferably, two grooves are provided parallel to the longitudinal direction of the tunnel on the inner side faces of the tunnel, the two grooves being symmetrical with respect to the median plane of the rim perpendicular to the axis. These two grooves are intended to guide a flat or extension blade, the two longitudinal edges of which are inserted into the grooves from the entrance to the tunnel.

L'outillage comprend aussi un coulisseau que la lame de rallonge est destinée à rallonger et qui est introduit dans le tunnel par la sortie de celui-ci. Le coulisseau a sur la face inférieure une rainure transversale de plus grande largeur que le diamètre du joint. Lors du déroulement du joint de la roue servant de dérouleur, un brin curviligne du joint tombe automatiquement dans cette rainure lors du coulissement dans le tunnel. Cela permet ensuite de poser le joint dans l'injecteur.The tool also comprises a slider that the extension blade is intended to lengthen and which is introduced into the tunnel through the outlet thereof. The slider has on the underside a transverse groove of greater width than the diameter of the seal. When unwinding the seal from the wheel serving as an unwinder, a curvilinear strand of the seal automatically falls into this groove as it slides through the tunnel. This then allows the seal to be placed in the injector.

Par face inférieure du coulisseau, on entend la face qui est tournée vers le mors par opposition à celle tournée vers le corps, lorsque le coulisseau est introduit dans l'injecteur. Mais cette face n'est pas forcément en dessous de l'autre face suivant la position de l'injecteur.By lower face of the slider, we mean the face which is turned towards the bit as opposed to that facing the body, when the slider is introduced into the injector. But this face is not necessarily below the other face depending on the position of the injector.

De préférence, le coulisseau a deux épaulements symétriques l'un de l'autre par rapport au plan longitudinal médian du coulisseau, conjuguées de deux butées sur les faces latérales du tunnel de manière à limiter la pénétration du coulisseau dans le tunnel, lorsque le coulisseau y est introduit par la sortie.Preferably, the slider has two shoulders symmetrical to each other with respect to the median longitudinal plane of the slider, combined with two stops on the side faces of the tunnel so as to limit the penetration of the slider into the tunnel, when the slider is introduced there through the output.

De préférence, le coulisseau est en trois parties, une première partie ayant une première face principale plane et une seconde face principale, opposée à la première, usinée en ayant une rampe et une rainure, une deuxième partie, formant lame de rallonge de moindre épaisseur que la première partie et dont la première face principale est à affleurement avec la première face principale de la première partie, et une troisième partie de maintien, qui maintient la deuxième partie sur la première partie.Preferably, the slider is in three parts, a first part having a first flat main face and a second main face, opposite the first, machined by having a ramp and a groove, a second part, forming an extension blade of less thickness than the first part and whose first main face is flush with the first main face of the first part, and a third holding part, which holds the second part on the first part.

De préférence, un plat d'accompagnement est fixé de manière amovible au fond du tunnel et se prolonge au-delà de la sortie du tunnel. Le guidage du joint et son introduction dans la gorge du coulisseau sont ainsi bien assurés. Ce plat, qui pourrait aussi venir de matière avec la chape, est fragile et serait, dans ce dernier cas, susceptible de se casser. Il vaut mieux qu'il soit une pièce séparée de la chape.Preferably, a side dish is removably attached to the bottom of the tunnel and extends beyond the tunnel exit. The guiding of the seal and its introduction into the groove of the slider are thus well ensured. This plate, which could also come from material with the yoke, is fragile and would, in the latter case, be likely to break. It is better if it is a separate piece from the screed.

Pour assurer un bon guidage lors de l'entrée du coulisseau dans l'injecteur, la chape a deux cornes. Les deux cornes sont issues de la chape dans le sens de sortie du tunnel et dépassent du plat d'accompagnement dans le sens de la sortie du tunnel.To ensure good guidance when the slider enters the injector, the yoke has two lugs. The two horns come from the clevis in the direction of the exit of the tunnel and protrude from the side dish in the direction of the exit of the tunnel.

L'invention a également pour objet un procédé de pose d'un joint en élastomère sans fin dans un injecteur, à l'aide d'un outillage suivant l'invention, dans lequel on enroule un joint sur la roue en le faisant passer dans les deux encoches, on introduit le brin curviligne libre (celui qui n'est pas accroché) du joint dans le tunnel par l'entrée du tunnel en le faisant traverser le tunnel et on le passe en dessous du plat d'accompagnement, on introduit le coulisseau dans le tunnel par la sortie de celui-ci, côté rainure tournée vers le plat d'accompagnement, on introduit le brin curviligne libre dans la rainure du coulisseau, on aboute le plat de rallonge au coulisseau et on introduit l'ensemble du coulisseau et du plat de rallonge dans la chambre de l'injecteur jusqu'à ce que le brin curviligne tombe dans la gorge de réception de ce brin du joint dans la chambre de l'injecteur comme décrit au brevet français 2 902 035 .The invention also relates to a method for fitting an endless elastomer seal in an injector, using a tool according to the invention, in which a seal is wound on the wheel by passing it through the two notches, we introduce the free curvilinear strand (the one that is not hooked) of the seal into the tunnel through the entrance of the tunnel by making it cross the tunnel and we pass it below the side dish, we introduce the slider in the tunnel through the outlet of the latter, groove side facing the accompanying plate, the free curvilinear strand is introduced into the groove of the slider, the extension plate is joined to the slider and the whole of the slider and extension plate into the injector chamber until the curvilinear strand falls into the groove of the reception of this strand of the joint in the chamber of the injector as described in the patent French 2,902,035 .

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 '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 of elastomeric material. As shown in picture 2 , the groove 6 has two straight 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), which are both bounded only by an inner edge. In these curved end parts, the groove is said to be open. A part of a joint which falls within the range thus delimited will easily come to rest on the edge 14 by elastic return, if the joint 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 inférieure 18; dans laquelle est usinée la gorge 6.We see at the picture 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 de pose d'un joint torique en élastomère sans fin représenté aux figures 3 à 7 comprend une roue 20, de la jante 21 de laquelle est issu un seul crochet 22, dont la partie 23 incurvée de manière concave a le même rayon de courbure que le tore du joint qui est destiné à s'y accrocher et avec laquelle le joint est en contact. Le crochet 22 s'étend dans le plan médian de la jante 21 perpendiculaire à l'axe 24 de la roue. Un joint 19 sans fin torique en matière élastomère est accroché par l'un de ses brins curvilignes au crochet 23 (voir la figure 7) et est enroulé autour de la jante 21. Il est défini sur la face extérieure de l'âme 30 deux encoches 28, 29 parallèles à la direction longitudinale d'un tunnel défini dans l'âme 30, qui débouchent sur la face frontale d'entrée du tunnel et servent à guider le joint 19 et à en bien paralléliser les brins rectilignes à l'enroulement. Les deux encoches 28, 29 sont symétriques l'une de l'autre par apport au plan médian. La roue est de symétrie par rapport au plan médian perpendiculaire à l'axe. Le tunnel défini par l'âme 30 de la chape est rectiligne. Sa longueur est de 10 cm.. Sur les faces latérales intérieures du tunnel sont prévues deux rainures 33, 34 d'introduction d'un plat de rallonge 47. Le tunnel a un fond constitué par un plat 35 d'accompagnement du joint, lorsque celui-ci passe dans le tunnel de l'entrée vers la sortie. Le plat 35 dépasse du tunnel et a à son extrémité une forme concave, qui s'adapte à la forme de la gorge de joint dans sa partie en regard de la lumière.The tools for fitting an endless elastomer O-ring shown in figures 3 to 7 comprises a wheel 20, from the rim 21 of which comes a single hook 22, the concavely curved part 23 of which has the same radius of curvature as the torus of the joint which is intended to be hooked thereto and with which the joint is in touch. The hook 22 extends in the median plane of the rim 21 perpendicular to the axis 24 of the wheel. An endless O-ring 19 made of elastomeric material is attached by one of its curvilinear strands to the hook 23 (see the figure 7 ) and is wound around the rim 21. There are defined on the outer face of the core 30 two notches 28, 29 parallel to the longitudinal direction of a tunnel defined in the core 30, which open onto the front face of entrance to the tunnel and serve to guide the gasket 19 and to properly parallelize the straight strands when winding. The two notches 28, 29 are symmetrical to each other with respect to the median plane. The wheel is symmetrical with respect to the median plane perpendicular to the axis. The tunnel defined by the core 30 of the yoke is rectilinear. Its length is 10 cm. On the inner side faces of the tunnel are provided two grooves 33, 34 for the introduction of an extension plate 47. The tunnel has a bottom formed by a plate 35 accompanying the joint, when it passes through the tunnel from the entrance to the exit. Flat 35 protrudes from the tunnel and has a concave shape at its end, which adapts to the shape of the seal groove in its part facing the light.

Une tige 36 crochue est montée à coulissement dans une rainure 37 sur une face extérieure d'une joue 31 de la chape. Le bas du tunnel est constitué par le plat 35.A hooked rod 36 is slidably mounted in a groove 37 on an outer face of a flange 31 of the yoke. The bottom of the tunnel is formed by plate 35.

Le coulisseau, en un matériau qui glisse facilement sur de l'inox comme de l'ABS, est constitué d'un patin ayant une face 40 supérieure, rectangulaire, plane et lisse. La face latérale gauche, de l'outillage (à la figure 6) est en forme de T ayant une hampe 41 et une barrette 42. La barrette 42 est rectangulaire, en ayant une largeur de 20 mm et une hauteur de 10 mm. La hampe 41 est sensiblement rectangulaire, d'une largeur de 10 mm et d'une hauteur de 5 mm. La hauteur de l'outillage H est de 10 mm. La face inférieure (supérieure à la figure) de la hampe 41 est plane et parallèle à la face 40. La hampe 41 constitue un plot ou toc d'entraînement, en étant interrompue par une rainure 43 ouverte vers le bas (vers le haut à la figure). Un joint peut être mis dans cette rainure 43 et enfilé ainsi autour du toc 41. De l'autre côté de la rainure 43, la face inférieure se poursuit par une barre 44 centrale longitudinale sur laquelle est apposée une flèche F indiquant le sens d'introduction du coulisseau. Deux rampes 45, symétriques l'une de l'autre par rapport à la barre 44, sont disposées sur les bords longitudinaux de l'outillage. Les rampes sont inclinées suivant une pente de 15° de la surface inférieure 42 de la barre à une plateforme 46 la plus basse de l'outillage qui est au même niveau que la face inférieure de la hampe 41 et que la barre 44.The slider, made of a material which slides easily on stainless steel such as ABS, consists of a shoe having an upper face 40 which is rectangular, flat and smooth. The left side face, of the tooling (at the figure 6 ) is T-shaped having a shaft 41 and a bar 42. The bar 42 is rectangular, having a width of 20 mm and a height of 10 mm. The stem 41 is substantially rectangular, with a width of 10 mm and a height of 5 mm. The height of the tool H is 10 mm. The lower face (upper in the figure) of the shaft 41 is flat and parallel to the face 40. The shaft 41 constitutes a stud or drive dog, being interrupted by a groove 43 open downwards (upwards at the figure). A seal can be placed in this groove 43 and thus threaded around the dog 41. On the other side of the groove 43, the lower face continues with a central longitudinal bar 44 on which is affixed an arrow F indicating the direction of introduction of the slider. Two ramps 45, symmetrical to each other with respect to bar 44, are arranged on the longitudinal edges of the tool. The ramps are inclined at a 15° slope from the lower surface 42 of the bar to a lowest platform 46 of the tool which is at the same level as the underside of the shaft 41 and the bar 44.

Le coulisseau a deux épaulements 51 (voir les figures 8 et 9) conjugués de deux épaulements 52 des faces latérales intérieures de la chape. Deux cornes 53 sont issues des joues 31 de la chape dans le prolongement des faces latérales du tunnel. La distance hors-tout des cornes 53 est juste inférieure à la largeur de la lumière de l'injecteur.The slider has two shoulders 51 (see the figures 8 and 9 ) combined with two shoulders 52 of the inner side faces of the yoke. Two horns 53 come from the cheeks 31 of the yoke in the extension of the side faces of the tunnel. The overall distance of the horns 53 is just less than the width of the injector lumen.

L'outillage comprend aussi un plat 47 de rallonge (voir la figure 6) constitué d'un feuillard ou lame d'acier inoxydable enroulable fixé de manière amovible au coulisseau à l'aide d'une pièce 48 de maintien ayant un doigt 49, qui pénètre dans un trou 50 du coulisseau avec interposition du plat 47. La pièce 48 de maintien est vissée au coulisseau par deux vis 51.The tool also includes an extension flat 47 (see figure 6 ) consisting of a roll-up stainless steel strip or blade removably fixed to the slider by means of a holding part 48 having a finger 49, which penetrates into a hole 50 of the slider with the interposition of the flat 47. The retaining piece 48 is screwed to the slider by two screws 51.

On utilise l'outillage de mise en place d'un joint dans la gorge 6 de la manière suivante :
Après que l'on a enroulé un joint 19 sur la roue en accrochant le joint au crochet 22 et avoir pris soin d'enrouler le joint 19 en le faisant passer dans les encoches 28, 29, on introduit le brin curviligne libre du joint 19 dans le tunnel par l'entrée du tunnel en le faisant traverser le tunnel et on le passe en dessous du plat 35 d'accompagnement, on introduit le coulisseau dans le tunnel par la sortie de celui-ci, côté rainure 43 tournée vers le plat 35 d'accompagnement, jusqu'à introduction du brin curviligne libre dans la rainure 43 du coulisseau, on aboute le plat 47 de rallonge au coulisseau et on introduit l'ensemble du coulisseau et du plat 47 de rallonge par une lumière de l'injecteur dans la chambre de l'injecteur jusqu'à ce que le brin curviligne tombe dans la gorge de réception de ce brin du joint dans la chambre de l'injecteur comme décrit au brevet français 2 902 035 .The tooling for fitting a seal in groove 6 is used as follows:
After a seal 19 has been rolled up on the wheel by hooking the seal to the hook 22 and having taken care to roll up the seal 19 by passing it through the notches 28, 29, the free curvilinear strand of the seal 19 is introduced. into the tunnel through the entrance to the tunnel by making it cross the tunnel and it is passed below the accompanying plate 35, the slider is introduced into the tunnel through the exit thereof, groove side 43 facing the plate 35 of accompaniment, until the introduction of the free curvilinear strand into the groove 43 of the slider, the extension plate 47 is butted to the slider and the assembly of the slider and the extension plate 47 are introduced through a lumen of the injector in the chamber of the injector until the curvilinear strand falls into the groove for receiving this strand of the seal in the chamber of the injector as described in the patent French 2,902,035 .
