Abstract

Equipment for welding plastic profiles together to form frames for windows, doors or similar structures includes a side tool(6) which lies in contact with the profile at each welding seam. The side tool(6) has a blade(5) which forms a side edge to the welding bead and is moved horizontally along a prescribed stroke length to and from the area of welding bead formation by a drive unit(3)

Description

1i 2765822 L'invention concerne un dispositif de soudage de profilés en1i 2765822 The invention relates to a device for welding profiles in

matière plastique pour constituer au moins un cadre pour fenêtres, portes ou analogues, avec à chaque fois un outil de délimitation, susceptible d'être mis en appui avec le profilé dans la zone du cordon de soudure à réaliser, présentant à chaque fois une arête latérale positionnable sur le cordon de  plastic material to constitute at least one frame for windows, doors or the like, each time with a delimiting tool capable of being supported with the profile in the area of the weld bead to be produced, each having an edge side positionable on the cord

soudure à réaliser et servant de lame de délimitation.  welding to be performed and serving as a delimitation blade.

Dans les machines à souder ou les groupes à souder, conçus pour souder des fenêtres en matière plastique, surtout dans le cas de machines à souder multitêtes, pour délimiter les cordons de soudure sur les faces visibles des fenêtres et des portes, sont prévues ce que l'on appelle des lames de délimitation, au moyen desquelles on réduit la largeur des bourrelets de soudure existants et provenant du soudage des profilés sur les faces intérieure et extérieure. Le réglage de l'intervalle et, ainsi, de la réduction de ces bourrelets est alors différent selon le système de profilé. Lorsque les profilés sont blancs ou colorés dans la masse, l'intervalle est usuellement de 1,5 à 2 mm entre les tranchants de lames, placés en regard des lames de délimitation. Une telle valeur d'intervalle est pertinente car on obtient ainsi un  In welding machines or welding groups, designed to weld plastic windows, especially in the case of multi-head welding machines, to delimit the weld beads on the visible faces of windows and doors, so-called delimitation blades are used, by means of which the width of the existing weld beads resulting from the welding of the profiles on the inner and outer faces is reduced. The setting of the interval and thus of the reduction of these beads is then different depending on the profile system. When the profiles are white or colored in the mass, the interval is usually 1.5 to 2 mm between the cutting edges of the blades, placed opposite the delimiting blades. Such an interval value is relevant because we thus obtain a

soudage solide.solid welding.

Cependant, dans le cas de feuilles multifilms à couches acryliques, les lames de délimitation doivent  However, in the case of multi-film sheets with acrylic layers, the boundary blades must

être réglées à un intervalle sensiblement égal à zéro.  be set at an interval substantially equal to zero.

Du fait de l'existence préalable possible d'une structure multifilms sur la face extérieure ou intérieure ou bien également sur la face extérieure et intérieure des fenêtres ou des portes, il faut que toutes les lames de délimitation prévues à cet endroit soient réglées de manière appropriée. Ceci s'avère nécessaire car, dans le cas, par exemple, de profilés multifilms reproduisant une boiserie, un intervalle  Due to the possible prior existence of a multifilm structure on the exterior or interior face or also on the exterior and interior face of windows or doors, it is necessary that all the delimitation blades provided at this location are adjusted so appropriate. This is necessary because, in the case, for example, of multi-film profiles reproducing a woodwork, an interval

plus large procure un effet inesthétique.  wider provides an unsightly effect.

Le réglage des lames de délimitation s'effectue cependant usuellement manuellement, o, le cas échéant, la mise à disposition d'un calibre de réglage peut s'avérer utile. Le réglage manuel constitue alors un facteur temporel essentiel lors du soudage des profilés en matière plastique. Dans le cas d'une machine de soudage à quatre têtes, il faut régler l'intervalle d'une quantité de lames allant jusqu'à seize. La durée nécessaire pour ce faire est d'au moins un quart d'heure par angle de cadre à fabriquer, le régleur devant également montrer une grande habileté  The adjustment of the delimitation blades is however usually done manually, where, if necessary, the provision of an adjustment gauge may prove useful. Manual adjustment is therefore an essential time factor when welding plastic profiles. In the case of a four-head welding machine, the interval between the quantity of blades up to sixteen must be adjusted. The time required to do this is at least a quarter of an hour per frame angle to be manufactured, the adjuster must also show great skill

pour opérer le réglage manuel.to operate the manual adjustment.

L'invention a de ce fait comme but de perfectionner un dispositif du type cité en introduction en ce que, de manière simple, rapide et satisfaisante, on puisse effectuer, sur la totalité des quatre angles d'un cadre en matière plastique, un réglage simple de l'intervalle, au niveau des cordons  The object of the invention is therefore to improve a device of the type mentioned in the introduction in that, in a simple, rapid and satisfactory manner, it is possible to carry out, over all the four angles of a plastic frame, an adjustment simple interval, at the cords

Selon l'invention, le but énoncé de l'invention est atteint par un dispositif du type cité en introduction dans lequel la lame de délimitation est déplaçable automatiquement d'une valeur de déplacement prédéterminée, au moyen d'un entraînement y relatif, sensiblement horizontal dans la direction du bourrelet de soudage à réaliser et montée en rappel dans sa  According to the invention, the stated aim of the invention is achieved by a device of the type mentioned in the introduction in which the delimiting blade is automatically movable by a predetermined displacement value, by means of a substantially horizontal relative drive. in the direction of the welding bead to be produced and rappelled in its

position initiale.initial position.

Selon l'invention, les différentes lames de délimitation sont déplacées automatiquement individuellement dans la machine de soudage de la valeur prédéterminée de déplacement et ainsi également de façon plus précise que dans le cas, par exemple,  According to the invention, the different delimitation blades are moved automatically individually in the welding machine by the predetermined displacement value and thus also more precisely than in the case, for example,

d'un réglage manuel.manual adjustment.

Le réglage de l'intervalle des lames de délimitation peut s'effectuer alors de façon optimale  The setting of the interval of the boundary blades can then be carried out optimally

et rapide selon le profil travaillé.  and fast according to the profile worked.

De préférence, l'entraînement est relié à un  Preferably, the drive is connected to a

3 27658223 2765822

dispositif de commande mémorisant la course de déplacement. De cette manière, les lames de délimitation peuvent être réglées automatiquement par  control device memorizing the travel stroke. In this way, the boundary blades can be adjusted automatically by

l'intermédiaire d'un code ayant été introduit.  through a code that has been entered.

L'entraînement, selon un perfectionnement, est constitué par un servomoteur électrique ou électropneumatique. De ce fait, la lame de délimitation est, de préférence, reliée à un vérin provoquant le déplacement, par exemple un vérin pneumatique. Un tel vérin peut, de manière simple, être disposé sur la  The drive, according to an improvement, is constituted by an electric or electropneumatic servomotor. Therefore, the delimiting blade is preferably connected to a cylinder causing displacement, for example a pneumatic cylinder. Such a jack can, in a simple manner, be arranged on the

plaque d'embase de la machine de soudage.  base plate of the welding machine.

Du fait que la lame de délimitation est déplaçable à chaque fois de cette manière, les lames de délimitation peuvent, après l'assemblage à jointement des profilés pour le soudage de ceux-ci, être rétractées simplement dans leur position initiale, afin que les bourrelets de soudage se constituant dans l'espace intermédiaire existant entre deux lames de délimitation ne soient pas soumis au risque d'être déchirés. Ceci est empêché de façon fiable par la sortie latérale des lames de délimitation sous le  Due to the fact that the delimiting blade is movable each time in this way, the delimiting blades can, after joining together the profiles for welding them, be simply retracted in their initial position, so that the beads welding formed in the intermediate space between two delimiting blades are not subject to the risk of being torn. This is reliably prevented by the lateral exit of the boundary blades under the

bourrelet respectif de soudage.respective welding bead.

Pour limiter le déplacement des lames de délimitation dans leur position sortie ainsi que dans leur position d'avance afin de former l'intervalle destiné aux bourrelets de soudage se constituant, sont prévues de préférence des butées destinées à délimiter le déplacement horizontal de la lame de délimitation dans la direction de l'avance et du rappel. Il s'agit alors de préférence de butées réalisées sous la forme à chaque fois de deux vis de butée dont l'une au moins est déplaçable avec la lame de délimitation et les  In order to limit the displacement of the delimitation blades in their extended position as well as in their advance position in order to form the gap intended for the forming welding beads, there are preferably provided stops intended to delimit the horizontal displacement of the delimitation in the direction of advance and recall. These are then preferably stops produced in the form each time of two stop screws, at least one of which is movable with the delimiting blade and the

autres disposées de façon localement fixe.  others arranged locally fixed.

Selon un perfectionnement, il est prévu que la lame de délimitation est à chaque fois verrouillable dans ses positions finales, si bien que, en particulier pendant le soudage, on empêche un déplacement  According to an improvement, it is provided that the delimiting blade is each time lockable in its final positions, so that, in particular during welding, movement is prevented

de diminuer l'intervalle.to decrease the interval.

Selon un perfectionnement, la fixation de la lame est prévue déplaçable horizontalement, dans la direction d'avance de la lame de délimitation. Cette fixation peut par exemple être constituée par une vis,  According to an improvement, the fixing of the blade is provided that can be moved horizontally, in the direction of advance of the delimiting blade. This fixing can for example be constituted by a screw,

montée dans un trou oblong ménagé sur une plaque-  mounted in an oblong hole made on a plate-

support de l'outil de délimitation destiné à la lame de délimitation. Ce faisant, le déplacement de la lame de délimitation vers les extrémités du profil à souder  support of the delimitation tool intended for the delimitation blade. In doing so, the displacement of the boundary blade towards the ends of the profile to be welded

ainsi que dans le sens contraire n'est pas empêché.  as well as in the opposite direction is not prevented.

Selon un perfectionnement, il est prévu un guidage s'étendant horizontalement pour la lame de délimitation. Celui-ci est alors de préférence constitué par une rainure servant de guidage longitudinal ainsi qu'un palier à billes. La rainure  According to an improvement, there is provided a guide extending horizontally for the delimiting blade. The latter is then preferably constituted by a groove serving as longitudinal guide as well as a ball bearing. The groove

peut alors, à son tour, être réalisée dans la plaque-  can then, in turn, be made in the plate-

support destinée à la lame de délimitation. Grâce à ce guidage longitudinal, lors du déplacement de la lame de  support for the boundary blade. Thanks to this longitudinal guide, during the movement of the blade

Evidemment, il est prévu que de tels outils de délimitation puissent être disposés tant façade supérieure et inférieure, respectivement en façade intérieure qu'également extérieure des profilés à souder. Ces outils de délimitation qui présentent des lames de délimitation selon l'invention sont alors commandés par un dispositif classique de commande, destiné à déplacer les lames de délimitation pour les régler. Le réglage de la lame de délimitation peut alors être effectué sur la face supérieure ou inférieure, o bien sur le côté supérieur ou inférieur des profilés, indépendamment les uns des autres selon  Obviously, provision is made for such delimitation tools to be arranged both on the upper and lower facades, respectively on the inner and on the outer facades of the profiles to be welded. These delimitation tools which have delimitation blades according to the invention are then controlled by a conventional control device, intended to move the delimitation blades to adjust them. The adjustment of the delimitation blade can then be carried out on the upper or lower face, or indeed on the upper or lower side of the profiles, independently of each other according to

les conditions que l'on a au moment du soudage.  the conditions that one has at the time of welding.

étendue sur la surface des profilés 101, 102.  extended over the surface of the sections 101, 102.

Pour assurer le guidage et la fixation de la lame de délimitation 5, l'outil de délimitation 6 présente une plaque-support 8. Dans la plaque-support 8 est prévue une rainure 9 servant de guidage longitudinal et s'étendant dans la direction de déplacement de la lame de délimitation 5. La lame de délimitation 5 peut être guidée de façon satisfaisante, lors de l'avance et du retrait, dans cette rainure 9,  To guide and fix the delimiting blade 5, the delimiting tool 6 has a support plate 8. In the support plate 8 is provided a groove 9 serving as longitudinal guide and extending in the direction of displacement of the delimitation blade 5. The delimitation blade 5 can be guided satisfactorily, during advancement and withdrawal, in this groove 9,

au moyen de paliers à billes 10 ou analogues.  by means of ball bearings 10 or the like.

En outre, l'outil de délimitation 6 présente une fixation de lame 11 déplaçable qui, par exemple, est constituée par un trou oblong s'étendant parallèlement à la rainure 9 ainsi qu'une vis de fixation. Aux deux extrémités opposées du tranchant 7 du genre lame de couteau, l'outil de délimitation 6 est pourvu respectivement de butées 12, 13, 14, 15, dont à chaque fois deux butées sont disposées sur l'un des deux côtés sans tranchant 7. Les butées 12, 13, 14, 15 sont chacune constituées par des vis de butées dont la vis de butée 14 est fixée sur la lame de délimitation 5 et se déplace avec celle-ci lors du déplacement. La vis de butée 15, disposée sur le côté de la vis de butée 14 parallèlement à celle-ci, est fixée sur la plaque d'embase 2 ou sur une autre partie localement fixe et montée fixe par rapport au déplacement de la lame de délimitation 5. La plaque d'embase 2 présente, sur son extrémité latérale tournée vers l'outil de délimitation, pour recevoir les vis de butée 14, 15, une cannelure 16 dont le fond 17 sert de surface de butée pour la tête de vis 18 de la vis de butée 14. La tête 19 de la vis de butée 15 localement fixe, par contre, traverse par sa tige la lame de délimitation 5, et est disposée à l'intérieur d'un trou oblong 20 s'étendant parallèlement à la surface latérale de  In addition, the delimiting tool 6 has a movable blade attachment 11 which, for example, consists of an oblong hole extending parallel to the groove 9 as well as a fixing screw. At the two opposite ends of the cutting edge 7 of the knife blade type, the delimiting tool 6 is provided respectively with stops 12, 13, 14, 15, each of which two stops are arranged on one of the two sides without cutting edge 7 The stops 12, 13, 14, 15 are each constituted by stop screws, the stop screw 14 of which is fixed on the delimiting blade 5 and moves with the latter during movement. The stop screw 15, arranged on the side of the stop screw 14 parallel to the latter, is fixed to the base plate 2 or to another locally fixed part and mounted fixed relative to the movement of the delimitation blade 5. The base plate 2 has, on its lateral end facing the delimitation tool, to receive the stop screws 14, 15, a groove 16 whose bottom 17 serves as a stop surface for the screw head 18 of the stop screw 14. The head 19 of the locally fixed stop screw 15, on the other hand, passes through its rod the delimiting blade 5, and is disposed inside an oblong hole 20 extending parallel to the lateral surface of

l'outil de délimitation 6 dans cette zone. Elle vient avec sa tête 19, lors du déplacement de la lame de délimitation 5, dans la direction du cordon de soudure, en appui sur la face intérieure, tournée vers la plaque d'embase 2, du trou oblong 20. Pour monter les vis de butée 12, 13, la lame de délimitation 5 présente un évidement 21 parallèle à la rainure 9 et à la face latérale afférente, dont les faces d'extrémité 22, 23 servent de surfaces de butée pour les têtes 24, 25, orientées à l'opposé les unes des autres, des vis de butée 12, 13. Les vis de butée 12, 13 sont alors chacune orientées à l'opposé l'une de l'autre sur une pièce de fixation 26 qui est par exemple fixée sur la plaque- support 8. De cette façon, lors du déplacement de la lame de délimitation 5, dans l'une ou l'autre direction, à chaque fois l'une des vis 12, 13 vient en appui par sa tête 24, 25, sur les faces de butée 22, 23 de  the delimitation tool 6 in this zone. It comes with its head 19, during the displacement of the delimitation blade 5, in the direction of the weld bead, bearing on the inner face, facing the base plate 2, of the oblong hole 20. To mount the screws 12, 13, the delimiting blade 5 has a recess 21 parallel to the groove 9 and to the associated lateral face, the end faces 22, 23 of which serve as abutment surfaces for the heads 24, 25, oriented at opposite to each other, stop screws 12, 13. The stop screws 12, 13 are then each oriented opposite one another on a fixing piece 26 which is for example fixed on the support plate 8. In this way, during the displacement of the delimiting blade 5, in one or the other direction, each time one of the screws 12, 13 comes to bear by its head 24, 25 , on the abutment faces 22, 23 of

l'évidement 21.the recess 21.

En actionnant le vérin 3, on peut ainsi déplacer la lame de délimitation 5 avec son tranchant 7 du genre lame de couteau, dans la direction du cordon de soudure 103 (figure 2, figures 1 à 4). On délimite alors au moyen des butées 12 à 15 la longueur de la course de déplacement. Après soudage, la lame de délimitation 5 est rappelée dans la direction opposée en actionnant à nouveau le vérin 3, les butées 14 et 13  By actuating the jack 3, it is thus possible to move the delimitation blade 5 with its cutting edge 7 of the knife blade type, in the direction of the weld bead 103 (FIG. 2, FIGS. 1 to 4). The length of the displacement stroke is then defined by means of the stops 12 to 15. After welding, the delimiting blade 5 is returned in the opposite direction by actuating the jack 3 again, the stops 14 and 13

délimitant alors ici la course de déplacement.  then delimiting here the displacement race.

En raison du déplacement automatique de cette lame de délimitation 5, on peut souder de manière simple des profils les plus différents qui soient, grâce au réglage s'effectuant automatiquement de l'intervalle, en réalisant un bourrelet de soudure 104 pour un réglage de 2 mm (figure 3) ou 105 pour un réglage d'intervalle d'environ 0,2 mm, entre les  Due to the automatic movement of this delimiting blade 5, it is possible to weld the most different profiles in a simple manner, by virtue of the adjustment being effected automatically of the interval, by producing a weld bead 104 for an adjustment of 2 mm (Figure 3) or 105 for an interval setting of approximately 0.2 mm, between the

tranchants 107 du genre lame de couteau.  sharp 107 knife blade type.
