Abstract
Description
L'invention concerne un procédé et une machine de mise on
oeuvre du procddd, pour obturer les extrémités de profilés en
matière plastique pour double vitrage notamment.The invention relates to a method and a machine for setting
work of the procddd, to close the ends of profiles in
plastic material for double glazing in particular.
Ltobjet de l'Invention se rattache notamment aux secteurs
techniques du travail des matières plastiques ainsi que des maté
riaux et éléments pour les fermetures à double vitrage des cons
tructions emploies dans le bâtiment.The object of the invention relates in particular to the sectors
techniques for working with plastics and materials
rials and elements for double glazing closures of cons
tructions used in the building.
Certains -profiles extrudés en matière plastique qui sont uti lisés notamment dans la réalisation de cadres de montaed des ------
doublesvitrages, tels que les profilés qui ont fait l'objet de précédents dépôts et notamment du Brevet français n 69.00917,
ont la déposante ost également la titulaire, sont constitués,
comme illustré à la figure G, par un profil extérieur (a) dé sec
tion en U avec éventuellement un prolongement inférieur (ai) en
équerre pour son scellement sur le dormant de l'ouverture, et d'un profil intérieur creux (b) à section en T, délimitant entre eux deux espaces (c-d) pour le logement des vitres (e) ou plaques. habituellement transparentes qui y sont fixées au moyen d'un matériau de scellement injecté.Certain extruded plastic profiles which are used in particular in the production of mounting frames for ------
double glazing, such as the profiles which have been the subject of previous filings and in particular French patent n 69.00917,
the applicant is also the licensee, are constituted,
as illustrated in figure G, by a dry external profile (a)
tion in U with possibly a lower extension (ai) in
bracket for its sealing on the frame of the opening, and of a hollow interior profile (b) with T-section, delimiting between them two spaces (cd) for the housing of the panes (e) or plates. usually transparent which are fixed to it by means of an injected sealing material.
L'assemblage des éléments généralement au nombre de quatre,
constituant le cadre de montage , s'opère dans les angles (voir
figure 7) par coupe on onglet (g) des profils extérieurs (a) et gé
néralement par une coupe (h) par fraisage le plus souvent du pro
fil intérieur (b) en T, perpendiculairement à la longueur du profilé. Ce mode d'assemblage laisse donc dans les angles un espace vide (,) qu'il raut ensuite colmater par une colle ou un produit
étanche. Néanmoins, et comme on l'a vérifié, ce produit peut avoir un certaine imperméa bitité à la vapeur d'eau qui peut passer entre les vitres provoquer des condensations nuisant a' la présentation et à la visi bilité. The assembly of the elements generally four in number,
constituting the mounting frame, operates in the corners (see
Figure 7) by section on tab (g) of the external profiles (a) and ge
usually by cutting (h) by milling most often the pro
inner wire (b) in T, perpendicular to the length of the profile. This method of assembly therefore leaves an empty space in the corners (,) which it is then necessary to seal with an adhesive or a product.
waterproof. However, and as has been verified, this product may have a certain impermeability to water vapor which can pass between the panes causing condensation which is detrimental to the presentation and to visibility.
Par ailleurs, on conçoit que ces opérations successives d'usi
nage du profil en T et de bouchage dans les angles sont longues et
coûteuses avec l'important inconvanient précité.Furthermore, it is understandable that these successive operations of usi
swimming T-profile and plugging in the corners are long and
expensive with the aforementioned important disadvantage.
C'est pourquoi, selon l'invention, on a cherché d obturer sans
apport de mare et sans usinage du profilé, le profil en T auN O-N
trémités du profilé, d'une manière mécanisée, autematique et rapide
avec une exécution parfaite. This is why, according to the invention, we have sought to seal without
contribution of pond and without machining of the profile, the T profile in ON
profile hoppers, mechanized, automatic and fast
with perfect execution.
Suivant une première caractéristique, on positionne longdtudi
nalement, transversalement et en hauteur, sur un support, le pro@i-
lé dont l'extrémité doit être préparée pour la coupe et l'obtura
2X.ion en vue de l'assemblage ; on fixe le dit profilé et son ex tremitc ; on chauffe et on coupe à la base le profil intérieur en T, sur la longueur nOcessaire pour ne pas gêner l'assemblage angulaire des extrémités des deux profilés ; on pivote la partie coupée etramollie à l'extrémité du profil en T, et on la rabat de façon à obturer, au moyen de cette partie coupée, l'extrémité du profil creux en T. According to a first characteristic, we position longdtudi
nally, transversely and in height, on a support, the pro @ i-
the end of which must be prepared for cutting and sealing
2X.ion for assembly; the said profile and its ex tremitc are fixed; the inner T-shaped profile is heated and cut at the base, over the necessary length so as not to hinder the angular assembly of the ends of the two profiles; the cut and softened cut part is pivoted at the end of the T-profile, and it is folded down so as to close off, by means of this cut part, the end of the hollow T-shaped profile
Suivant une autre caractéristique, la machine de mise en oeuvre de ce procédé d'obturation comprend : un support fixe recevant dans une position précise le profilé à obturer qui y est maintenu fermement par un moyen de serrage, un organe coupant équipé de moyen de chauffage, qui est monté coulissant sur un bâti monté articulé par rapport au support fixe, le dit organe coupant qui peut être pivoté par rapport au support fixe étant agencé pour séparer par ramolissement de matière, une partie du profil en T à l1extré- mité du profilé, puis de façon à rabattre la partie ramollie par pivotement du dit organe, afin d'obturer de manière étanche, sans apport de matière la section creuse du profil en T
Une autre caractéristique se trouve dans le fait que l'organe chauffant est un couteau en matériau conducteur, équipé intérieurement d'une résistance de chauffage et d'une sonde de contrôle précis de la température de flamoissement. According to another characteristic, the machine for implementing this sealing method comprises: a fixed support receiving in a precise position the profile to be closed which is held there firmly by a clamping means, a cutting member equipped with heating means , which is slidably mounted on a frame mounted articulated relative to the fixed support, the said cutting member which can be pivoted relative to the fixed support being arranged to separate by softening of material, part of the T-profile at the end of the profile , then so as to fold down the softened part by pivoting of the said member, in order to seal in a sealed manner, without adding material, the hollow section of the T-profile
Another characteristic is found in the fact that the heating element is a knife made of a conductive material, internally equipped with a heating resistor and a probe for precise control of the flaming temperature.
Suivant une autre caractéristique, le profilé à obturer est positionné sur le support fixe par l'intermédiaire de gabarits interchangeables suivant la section du profilé. According to another characteristic, the profile to be closed is positioned on the fixed support by means of interchangeable templates according to the section of the profile.
Ces caractéristiques et dtautres encore, ressortiront de la description qui suit. These characteristics and others will emerge from the description which follows.

Afin de rendre plus concret l'objet de l'invention, on le décrit maintenant sous une forme non limitative de realisation illustrée aux figures des dessins. In order to make the object of the invention more concrete, it is now described in a nonlimiting form of embodiment illustrated in the figures of the drawings.
La machine comprend un support fixe (1) constitu par exemple de deux montants (la) reliés à leur base par un socle (lb) équipé pour la fixation du support sur une surface quelconque. The machine comprises a fixed support (1) consisting for example of two uprights (la) connected to their base by a base (lb) equipped for fixing the support on any surface.
A la partie sùpérieure, le support reçoit en quatre points de fixation (A - B - C - D; par exemple, un gabarit (2) destiné au positionnement des profilés à obturer. A cet effet, le gabarit qui est de préférence en acier inoxydable ou matériau équivalent, présente intérieurement et dans le sens longitudinal, un rail d'appui et de guidage du profilé. Ce rail peut être de toute forme adaptée à la section du profilé. Dans l'exemple illustré, le rail est formé par deux barrettes longitudinales parallèles (2a) espacées lune de lg autre et avec les parois latérales du rail, de manière à délimiter un espace central pour le logement de la section en T du profilé et deux espaces latéraux pour le logement des ailes de la section en U du profilé dont le fond repose sur les barrettes. At the upper part, the support receives at four fixing points (A - B - C - D; for example, a template (2) intended for positioning the profiles to be closed. To this end, the template which is preferably made of steel stainless steel or equivalent material, internally and in the longitudinal direction, a support rail and guide of the profile. This rail can be of any shape adapted to the section of the profile. In the example illustrated, the rail is formed by two parallel longitudinal bars (2a) spaced one from the other and with the side walls of the rail, so as to delimit a central space for housing the T-section of the profile and two lateral spaces for housing the wings of the U-section of the profile whose bottom rests on the bars.
A une cxtrémité (en regard de l'organe d'obturation), les barrettes (2a) présentent des saillies (2b) destinées à servir de butée de positionnement au profilé engagé dans le rail. At one end (facing the closure member), the bars (2a) have projections (2b) intended to serve as positioning stops for the profile engaged in the rail.
Le profité placé on butée sur le gabarit est ensuite maintenu fermement dans cette position par tous moyens appropriés tels que levier à excentrique ou came, levier auto-verrouillable par système à parallélogramme -déformable et ressorts, ou encore coram.e illustré, figures i et 3, par un vérin double effet (3) qui est porté en (4) par le support fixe (l) et dont la tige de piston (3a) présente à son extrémité active une tête d'appui (3b) sur le profil .ai1.~ a- a quelle est exécutée une canalisation de fuite (3c) reliée au: : organes de commande de la machine pour empêcher son fonctionnement brs- qu'il n'y a pas de profilés mis en contact avec la tête (3b). The profit placed on the stopper on the template is then held firmly in this position by all appropriate means such as eccentric lever or cam, self-locking lever by parallelogram-deformable system and springs, or even coram.e illustrated, Figures i and 3, by a double-acting cylinder (3) which is carried at (4) by the fixed support (l) and whose piston rod (3a) has at its active end a support head (3b) on the profile. ai1. ~ a- to which is executed a leakage pipe (3c) connected to:: control members of the machine to prevent its operation brs- that there are no profiles brought into contact with the head (3b ).
Le gabarit (2) est équipé à son extrémité avant débordant du
support, d'axes (5) pour le montage à pivotement d'un bâti (6) cons titué essentiellement dtun profilé de section en U dont 1 patio avant a) présente des paliers ou bagues (7) de tourillonnement sur les exes (5), tandis que la partie arrière est fermée par une paroi (6b) de montage d'un moyen de commande en translations alternatives d'un organe chauffant (8) qui est constitué par un couteau en matériau conducteur de la chaleur.The template (2) is equipped at its front end projecting from the
support, of axes (5) for the pivoting mounting of a frame (6) consisting essentially of a U-shaped section of which 1 front patio a) has bearings or rings (7) of swiveling on the exes (5 ), while the rear part is closed by a wall (6b) for mounting a control means in alternative translations of a heating member (8) which is constituted by a knife made of heat conductive material.
La partie active (8a) effilée du couteau présente son arête face au profilé à obturer, au niveau de la ligne située entre le sons et la section en T du profile (figure 4). The tapered active part (8a) of the knife has its edge facing the profile to be closed, at the level of the line located between the sounds and the T-section of the profile (FIG. 4).
A l'intérieur, le couteau reçoit une résistance de chauffage (9) ainsi qu'une sonde de contrôle (10) sensible à L 5 C. Ces dispositifs sont reliés électriquement à tous moyens connus de distribution de courant et isolés par des plaques (il) en amiante ou autre matériau similaire accolés à une chape (12) sur laquelle est fixé le couteau qui est d'autre part guidé à coulissement par les ailes (6c) du bâti (6) coopérant avec des rainures latérales (lob) du couteau tigre 2). Inside, the knife receives a heating resistor (9) as well as a control probe (10) sensitive to L 5 C. These devices are electrically connected to all known means of current distribution and isolated by plates ( il) asbestos or other similar material attached to a yoke (12) on which is fixed the knife which is on the other hand guided by sliding by the wings (6c) of the frame (6) cooperating with lateral grooves (lob) of the tiger knife 2).
La chape (12) est reliée à l'arrière au moyen de commande du couteau qui peut être de toute nature et comme illustré à titre d' exemple, un vérin double effet (13) fixé sur la paroi (6b) du bâti~ et dont la tige du.piston (13a) est reliée à une équerre (14) art-- culée en (15) à la chape par une des ailes (14a), tandis que 1' autre aile (14b) est située en regard d'un organe (16) solidaire du bâti (6). The yoke (12) is connected to the rear by means of the knife control which can be of any kind and as illustrated by way of example, a double-acting cylinder (13) fixed to the wall (6b) of the frame ~ and whose rod du.piston (13a) is connected to a bracket (14) art-- abutment (15) to the yoke by one of the wings (14a), while one other wing (14b) is located opposite 'A member (16) integral with the frame (6).
L'organe (16) présente un orifice (15a) situé dans le champ de déplacement de l'aile (14b) de l'équerre (14) et communiquant avec une canalisation d'alimentation hydraulique ou pneumatique (16b) destinée à commander le pivotement du bâti (o) lorsque l'orifice (10a) est obturé par l'aile (14b), comme illustré fiqure 4. The member (16) has an orifice (15a) located in the field of movement of the wing (14b) of the bracket (14) and communicating with a hydraulic or pneumatic supply pipe (16b) intended to control the pivoting of the frame (o) when the orifice (10a) is closed by the wing (14b), as illustrated in FIG. 4.
et par exemple, par un vérin double effet (17) qui est monté a articulation libre en (18) entre les montants (la) du support fixe et dont une extrémité de la tige est articulée en (19) au bâti (6). and for example, by a double-acting cylinder (17) which is mounted with free articulation at (18) between the uprights (la) of the fixed support and one end of the rod of which is articulated at (19) to the frame (6).
On voit encore que lorsque le couteau (8) est pivoté selon figure S, la face inférieure (8c) de la partie active obture une canalisation (2c) formée sur la face avant (2d) du gabarit (2: et communiquant avec un organe (20) vissé dans le gabarit et relié hy- drauliquement ou pneumatiquement avec les moyens de commande de la machine. It can also be seen that when the knife (8) is pivoted according to FIG. S, the lower face (8c) of the active part closes a pipe (2c) formed on the front face (2d) of the template (2: and communicating with an organ (20) screwed into the template and connected hydraulically or pneumatically with the machine control means.
En se référant plus particulièrement aux figures , 4 et 5, on décrit maintenant le processus d'obturation des profilés avec la machine selon l'invention. Referring more particularly to Figures, 4 and 5, we now describe the process of closing the profiles with the machine according to the invention.
Le profilé à obturer (P) est positionné dans le gabarit (2) avec son extrémité en butée contre les saillies (2b) des barrette (2a), puis maintenu fermement en place par l'organe de serrage tEl que la tête (3b) du vérin (3) ou moyen similaire. A cet instant, le couteau (8) est dans la position représentée figure 1, c'est-àdire avec son arête au contact ou presque de l'extrémité du profilé (P). The profile to be closed (P) is positioned in the template (2) with its end in abutment against the projections (2b) of the bar (2a), then held firmly in place by the clamping member such as the head (3b) cylinder (3) or similar means. At this instant, the knife (8) is in the position shown in FIG. 1, that is to say with its edge in contact or almost with the end of the profile (P).
On chauffe alors le couteau (8) à l'aide de la résistance intérieure (9) jusqu'à une température déterminée en fonction du matériau du profilé et de l'épaisseur de matière à travailler. The knife (8) is then heated using the internal resistance (9) to a temperature determined according to the material of the profile and the thickness of material to be worked.
A titre indicatif, pour un profilé en matière plastique couramment employé dans la menuiserie de bâtiment, l'expérience a montré qu'il fallait chauffer le couteau à 3300C environ pour obtenir un ramollissement suffisant de la matière en vue de l'obturation par bouchage. As an indication, for a plastic profile commonly used in building joinery, experience has shown that the knife had to be heated to around 3300C to obtain sufficient softening of the material for sealing by plugging.
Lorsque le couteau est à température convenable, on agit sur le moyen de commande du couteau tel que le vérin (13), pour que sc arête active sépare. le fond (PI) du profilé et le profil en T (P2) par pénétration et ramolissement (flèche fl, figure 4), jusqu'à ce que l'aile (14b) de l'équerre (14) solidaire de la tige de vérin, obture l'orifice (16a) de l'organe (16) qui est relié au vérin (1 ou organe similaire de commande de pivotement du bâti (6) portant le couteau. When the knife is at a suitable temperature, action is taken on the knife control means such as the jack (13), so that the active edge separates. the bottom (PI) of the profile and the T-profile (P2) by penetration and softening (arrow fl, Figure 4), until the wing (14b) of the bracket (14) secured to the rod jack, closes the orifice (16a) of the member (16) which is connected to the jack (1 or similar member for controlling the pivoting of the frame (6) carrying the knife.
Le bâti (6) pivoté selon flèche f2, figure 5, permet au couteau (8) d'entraîner la matière ramollie du profilé dans un sens approximativement perpendiculaire à l'axe longitudinal du profilé, comme illustré figure 5. The frame (6) pivoted along arrow f2, FIG. 5, allows the knife (8) to drive the softened material of the profile in a direction approximately perpendicular to the longitudinal axis of the profile, as illustrated in FIG. 5.
Lorsque la face inférieure (8c) du couteau obture la caniisa tion (2c) débouchant sur la face avant (2d), l'action du vérin (1 est interrompue et le vérin (13) du bâti (6) est actionné pour autoriser le recul du couteau (8),.comme illustré en traits interror pus et par la flèche (f3) de la figure 5, ce qui permet d'obtenir l'obturation complète du profilé en même temps que le lissage de la paroi de fermeture ainsi constituée. When the lower face (8c) of the knife closes the caniisa tion (2c) leading to the front face (2d), the action of the jack (1 is interrupted and the jack (13) of the frame (6) is actuated to authorize the recoil of the knife (8), as illustrated in interror pus lines and by the arrow (f3) in FIG. 5, which makes it possible to obtain the complete obturation of the profile at the same time as the smoothing of the closure wall as well incorporated.
En fin de course arrière du vérin (13), le vérin de pivotemer
(17) ramène le bâti (6) dans la position Initiale, et la machine
est prête pour recommencer l'opération sur le profilé suivant.At the end of the rear stroke of the jack (13), the jack
(17) returns the frame (6) to the Initial position, and the machine
is ready to start again the operation on the next profile.
Les avantages ressortent bien dé. la description, on souligne
notamment': - L'obturation rationnelle des profilés sans apport de matière ni usinage du profilé, en une seule opération.The benefits are clear. the description, we underline
in particular ': - Rational sealing of the profiles without adding material or machining the profile, in a single operation.
- La simplicité et la fiSHlité de la machine qui peut être aisément montée en usine ou sur un chantier - Les nombreuses possibilités offertes par la machine, grâce à 1' interchangeabilité des gabarits selon la section du profilé à obturer - Les variantes possibles des moyens de commande et de serrage qui peuvent être adaptées à toutes cadences de production - La meilleure étanchéité obtenue entre les vitres par la matière du profilé remplaçant avantageusement les colles habituellement employées qui étaient plus ou moins perméables à la vapeur d'eau.- The simplicity and the reliability of the machine which can be easily assembled in the factory or on a building site - The numerous possibilities offered by the machine, thanks to the interchangeability of the templates according to the section of the profile to be closed - Possible variants of the means of control and tightening which can be adapted to all production rates - The best seal obtained between the panes by the material of the profile advantageously replacing the adhesives usually used which were more or less permeable to water vapor.
L'invention ne se limite aucunement à celui de ses modes d' application non plus qu'à ceux des modes de réalisation de ses diverses parties ayant plus spécialement été indiquées ; elle en embrasse au contraire toutes les variantes. The invention is in no way limited to that of its modes of application any more than to those of the embodiments of its various parts which have been more particularly indicated; on the contrary, it embraces all its variants.
