Description
La présente invention concerne un dispositif de fabrication de dalles de parois, notamment de dalles de 'plafonds, du type constitué d'un cadre sur lequel une toile est tendue. The present invention relates to a device for manufacturing wall tiles, in particular ceiling tiles, of the type consisting of a frame on which a canvas is stretched.
On connaît divers types de dalles de ce type qui sont habituellement destinées à constituer un plafond mais qui peuvent également, dans certains modes de mise en oeuvre, être utilisées pour constituer une paroi murale. De telles dalles de parois sont habituellement obtenues en collant sur un cadre rigide, notamment un cadre métallique, une toile de matière plastique constituée la plupart du temps de chlorure de polyvinyle, ou PVC, que l'on chauffe afin de la faire se dilater de façon, qu'après refroidissement, la rétraction de @la toile sur le cadre assure la tension de celle-ci. Une des difficultés d'un tel mode de mise en oeuvre est que la toile au cours du chauffage ne se dilate pas de façon uniforme, si bien qu'elle se déforme, ce qui rend complexe son opération de collage sur le cadre rigide. Various types of slabs of this type are known which are usually intended to constitute a ceiling but which can also, in certain embodiments, be used to constitute a wall wall. Such wall slabs are usually obtained by gluing on a rigid frame, in particular a metallic frame, a plastic fabric consisting mostly of polyvinyl chloride, or PVC, which is heated in order to make it expand by so that after cooling, the retraction of the canvas on the frame ensures the tension thereof. One of the difficulties of such an embodiment is that the fabric during heating does not expand uniformly, so that it deforms, which makes its bonding operation on the rigid frame complex.
La présente invention a pour but de proposer un dispositif semi-automatique permettant de réaliser de telles dalles, et plus particulièrement d'effectuer l'opération de tension de la toile et de collage de celle-ci sur un cadre rigide. The present invention aims to provide a semi-automatic device for making such slabs, and more particularly to perform the operation of tensioning the fabric and bonding it on a rigid frame.
La présente invention a ainsi pour objet un dispositif de fabrication de dalles de paroi, notamment de dalles de plafond, constituées d'un cadre sur lequel est fixée une toile tendue, caractérisé en ce qu'il comporte un bâti assurant le maintien - de moyens support de la toile, - de moyens de maintien de la périphérie de la toile sur les moyens supports, - de moyens de tension de la toile, - de moyens d'application et de maintien du cadre sur la toile. The present invention thus relates to a device for manufacturing wall tiles, in particular ceiling tiles, consisting of a frame on which a stretched canvas is fixed, characterized in that it comprises a frame ensuring the maintenance of - means canvas support, - means for holding the periphery of the canvas on the support means, - means for tensioning the canvas, - means for applying and holding the frame on the canvas.
Les moyens support de la toile peuvent préférablement 'être constitués d'un cadre support sur lequel on vient disposer la toile, et les moyens de maintien sont constitués d'un second cadre, ou cadre de pression, qui est monté mobile verticalement par rapport au cadre support et qui comporte des moyens aptes à exercer une pression sur la périphérie de la toile. The canvas support means may preferably consist of a support frame on which the canvas has been placed, and the holding means consist of a second frame, or pressure frame, which is mounted vertically movable relative to the support frame and which comprises means capable of exerting pressure on the periphery of the fabric.
Dans un mode de mise en oeuvre de l'invention la base du cadre de pression comportera sur sa périphérie un élément profilé en forme de U dont les ailes sont destinées à venir en application contre la toile afin d'assurer le maintien de celle-ci. In one embodiment of the invention, the base of the pressure frame will include on its periphery a U-shaped profiled element, the wings of which are intended to come into application against the fabric in order to maintain it. .
' Ce maintien pourra être amélioré en creusant sur la périphérie de la face supérieure du cadre support, sous les branches du profilé à section droite en forme de U, une rainure dans laquelle sera encastrée une bande élastique. 'This support can be improved by digging on the periphery of the upper face of the support frame, under the branches of the U-shaped cross section profile, a groove in which will be embedded an elastic band.
Préférablement les moyens de tension seront constitués d'un premier plateau, ou plateau inférieur, disposé dans l'axe de l'ouverture du cadre support, comportant des moyens de déplacement relatifs verticaux par rapport à celui-ci, de façon à soulever la toile lorsque celle-ci est maintenue entre les cadres support et de pression, afin de la tendre. Preferably the tensioning means will consist of a first plate, or lower plate, arranged in the axis of the opening of the support frame, comprising means of relative vertical displacement relative to the latter, so as to raise the canvas. when the latter is held between the support and pressure frames, in order to tension it.
Afin d'améliorer les qualités d'élasticité de la toile ,et la bonne mise sous tension de celle-ci, on dotera le plateau inférieur de moyens de chauffage, constitués préférablement de bandes conductrices basse tension sensiblement réparties sur toute la surface du plateau. In order to improve the elasticity qualities of the fabric, and the good tensioning of the latter, the lower plate will be provided with heating means, preferably made up of low-voltage conductive strips substantially distributed over the entire surface of the plate.
Les moyens d'application et de maintien du cadre sur la toile seront notamment constitués d'un second plateau, ou plateau supérieur, pourvu de moyens aptes à lui faire effectuer un déplacement vertical relatif par rapport au plateau inférieur. The means for applying and holding the frame on the canvas will in particular consist of a second plate, or upper plate, provided with means capable of causing it to make a relative vertical displacement relative to the lower plate.
on décrira ci-après, à titre d'exemple non limitatif, une forme d'exécution de la présente invention, en référence 'aux dessins annexés sur lesquels: La figure 1 est une vue en élévation d'un dispositif de fabrication de dalles de parois suivant l'invention. an embodiment of the present invention will be described below, by way of non-limiting example, with reference to the appended drawings in which: FIG. 1 is an elevation view of a device for manufacturing slabs of walls according to the invention.

La machine représentée de façon schématique sur les figures est essentiellement constituée d'un bâti métallique 1 constitué d'un cadre tubulaire rectangulaire de grand axe vertical et longitudinal yy', qui comprend un premier ,montant transversal 3 disposé sensiblement à partir du tiers inférieur du bâti 1 et qui est renforcé dans le sens longitudinal suivant l'axe yy' par deux longerons 5 disposés à 45 . The machine shown schematically in the figures essentially consists of a metal frame 1 consisting of a rectangular tubular frame of large vertical and longitudinal axis yy ', which comprises a first, transverse upright 3 disposed substantially from the lower third of the frame 1 and which is reinforced in the longitudinal direction along the axis yy 'by two longitudinal members 5 arranged at 45.
Par ailleurs le bâti 1 comporte, sensiblement à partir de son quart supérieur, un second montant transversal 7. Furthermore, the frame 1 comprises, substantially from its upper quarter, a second transverse upright 7.
Le dispositif suivant l'invention comporte un cadre 9 dit cadre de pression, qui est fixe par rapport au bâti 1 et qui est disposé dans un plan horizontal perpendiculaire à celui-ci. Le dispositif comprend également un plateau mobile inférieur 11 qui, en position de repos, est situé sous le cadre de pression 9 et qui est apte à se déplacer verticalement à l'intérieur de celui-ci, sous l'effet d'un vérin hydraulique 13 dont la base repose sur le montant 3. Un cadre horizontal métallique 15, dit cadre support, est situé sous le cadre de pression 9 et est relié au plateau mobile 11 par l'intermédiaire de ressorts de compression 18, de façon que tout mouvement vertical du plateau 11 provoque un déplacement du cadre 15 par l'intermédiaire des ressorts 18. The device according to the invention comprises a frame 9 called a pressure frame, which is fixed relative to the frame 1 and which is arranged in a horizontal plane perpendicular thereto. The device also comprises a lower movable plate 11 which, in the rest position, is located under the pressure frame 9 and which is capable of moving vertically inside of it, under the effect of a hydraulic cylinder. 13, the base of which rests on the upright 3. A metallic horizontal frame 15, called support frame, is located under the pressure frame 9 and is connected to the movable plate 11 by means of compression springs 18, so that any movement vertical of the plate 11 causes the frame 15 to move through the springs 18.
Le montant transversal supérieur 7 supporte un vérin 19 muni de deux guides latéraux 21. La partie inférieure du vérin 19 est solidarisée d'un plateau supérieur horizontal 23 de dimensions telles qu'il puisse pénétrer à l'intérieur du cadre de pression 9. The upper transverse upright 7 supports a jack 19 provided with two lateral guides 21. The lower part of the jack 19 is secured to a horizontal upper plate 23 of dimensions such that it can penetrate inside the pressure frame 9.
on a représenté de façon schématique, sur les figures 4a à 4f, les différentes étapes de fonctionnement du dispositif suivant l'invention. Ce fonctionnement s'établit ainsi que décrit ci-après Ainsi que représenté sur la figure 4a on dispose tout d'abord sur le cadre support 15 un morceau de toile 17 qui possède des dimensions assez supérieures à celles du cadre sur lequel on veut la fixer. on actionne ensuite le vérin ,hydraulique 13 de façon que celui-ci se déplace vers le haut entraînant le plateau il, ainsi que le cadre 15, par l'intermédiaire des ressorts 18. Dans un premier temps, la toile 17 se trouve pincée entre les cadres 15 et 9 avec une force F correspondant à la force de compression des ressorts 18 (figure 4b). Le plateau il poursuit son déplacement vers le haut et, dans un deuxième temps, il vient en contact avec la toile 17 qu'il déforme par élasticité, ce qui a pour effet d'assurer sa tension, ainsi que représenté sur la figue 4c. there is shown schematically, in Figures 4a to 4f, the different stages of operation of the device according to the invention. This operation is established as described below. As shown in FIG. 4a, there is first of all placed on the support frame 15 a piece of canvas 17 which has dimensions which are fairly larger than those of the frame on which it is desired to fix it. . the hydraulic actuator 13 is then actuated so that it moves upward, causing the plate there, as well as the frame 15, by means of the springs 18. Firstly, the fabric 17 is pinched between the frames 15 and 9 with a force F corresponding to the compression force of the springs 18 (Figure 4b). The plate continues its movement upwards and, in a second step, it comes into contact with the fabric 17 which it deforms by elasticity, which has the effect of ensuring its tension, as shown in FIG. 4c.
Une fois la tension de la toile 17 effectuée, on dispose sur celle-ci le cadre métallique 25 sur lequel on souhaite fixer la toile 17, après avoir distribué sur la périphérie de la surface externe de celui-ci une colle appropriée correspondant à la nature de la toile et à la nature métallique du support ainsi que représenté sur la figure 4d. on fera préférentiellement appel à une colle se présentant sous la forme d'un gel, afin d'éviter tout coulage sur les côtés du cadre métallique 25. Once the fabric 17 has been tensioned, the metal frame 25 is placed thereon on which it is desired to fix the fabric 17, after having distributed over the periphery of the external surface thereof an appropriate adhesive corresponding to the nature of the fabric and the metallic nature of the support as shown in FIG. 4d. a glue preferably in the form of a gel is preferably used, in order to avoid any leakage on the sides of the metal frame 25.
Une fois le cadre 25 mis en place sur la toile 17 on actionne le vérin hydraulique supérieur 19 de façon que celui-ci descende le plateau 23 et qu'il vienne en appui sur la partie postérieure du cadre 25 de façon à appliquer ce dernier contre la toile 17 et maintienne cet appui pendant un temps déterminé, à savoir le temps de prise de la colle utilisée (figure 4e). Once the frame 25 is in place on the canvas 17, the upper hydraulic cylinder 19 is actuated so that it descends the plate 23 and that it comes to bear on the rear part of the frame 25 so as to apply the latter against the canvas 17 and maintains this support for a determined time, namely the setting time of the adhesive used (Figure 4e).
Des moyens de temporisation, non représentés sur le dessin, agissent alors sur le vérin hydraulique 19 afin de remonter celui-ci et dégager l'accès à la dalle constituée du cadre 25 et de la toile 17. Dans le même temps on agit également sur le vérin hydraulique 13 de façon à descendre le plateau inférieur 11 et le cadre support 15. I1 reste alors à récupérer la dalle et à éliminer les parties de toile 17 qui débordent du cadre 25. Time delay means, not shown in the drawing, then act on the hydraulic cylinder 19 in order to raise the latter and clear access to the slab consisting of the frame 25 and the fabric 17. At the same time it also acts on the hydraulic jack 13 so as to descend the lower plate 11 and the support frame 15. I1 then remains to recover the slab and to eliminate the parts of fabric 17 which project beyond the frame 25.
Dans un mode de mise en oeuvre de l'invention, afin d'améliorer les qualités de déformabilité de la toile 17, on dispose à l'intérieur du plateau 11 des moyens 29 de chauffage de la toile. On fera préférentiellement appel à des dispositifs de chauffage électrique susceptibles d'être répartis de façon uniforme à l'intérieur du plateau il et en mesure de délivrer un chauffage doux et régulier. On retiendra ainsi préférablement les systèmes de chauffage par bandes conductrices basse tension. In one embodiment of the invention, in order to improve the deformability qualities of the canvas 17, there are inside the plate 11 means 29 for heating the canvas. Preferably, electrical heating devices capable of being distributed uniformly inside the plate 11 and capable of delivering gentle and regular heating will be used. It is thus preferable to retain the heating systems using low-voltage conductive strips.
On sait que l'une des difficultés rencontrées dans le collage d'une toile sur un cadre métallique est d'assurer une pression également répartie sur la totalité de la périphérie de ce cadre. Pour ce faire, ainsi que représenté sur la figure 2, la surface supérieure du plateau il, est creusée d'une rainure périphérique 30 de faible profondeur et d'une largeur a supérieure à celle de chacun des montants du cadre 25. Cette rainure 30 reçoit un élastomère 32. De même la face inférieure du plateau 23 est également creusée d'une rainure périphérique 34 remplie d'un élastomère 36. Dans ces conditions, on comprend que les possibilités de compression des élastomères 30 et 36 compensent les erreurs d'épaisseur se manifestant sur la périphérie du cadre métallique 25, si bien qu'en tout point de celui-ci la toile 17 est correctement appliquée contre le cadre. Afin d'améliorer la facilité de positionnement de la toile 17 lorsque l'on dispose celle-ci sur le plateau 11, on dépose, sur sa surface supérieure, un revêtement de Téflon 10, qui facilite le glissement de la toile 17 sur le plateau et son positionnement par rapport à celui-ci. De tels moyens sont particulièrement intéressants lorsque la toile est constituée de PVC qui a pour inconvénient de produire une certaine tendance à l'adhérence. We know that one of the difficulties encountered in bonding a canvas on a metal frame is to ensure a pressure equally distributed over the entire periphery of this frame. To do this, as shown in FIG. 2, the upper surface of the plate 11 is hollowed out with a peripheral groove 30 of shallow depth and a width a greater than that of each of the uprights of the frame 25. This groove 30 receives an elastomer 32. Similarly, the underside of the plate 23 is also hollowed out with a peripheral groove 34 filled with an elastomer 36. Under these conditions, it is understood that the possibilities of compression of the elastomers 30 and 36 compensate for the errors of thickness manifested on the periphery of the metal frame 25, so that at any point thereof the fabric 17 is correctly applied against the frame. In order to improve the ease of positioning the fabric 17 when it is placed on the plate 11, a Teflon coating 10 is deposited on its upper surface, which facilitates the sliding of the fabric 17 on the plate and its positioning in relation to it. Such means are particularly advantageous when the fabric is made of PVC which has the disadvantage of producing a certain tendency to adhesion.
Par ailleurs, ainsi que représenté sur la figure 5, afin d'améliorer le maintien de la périphérie de la toile 17 qui se trouve pincée entre les cadres 9 et 15, on dispose sous le cadre 9 un élément profilé 40 à section droite en U, dont les deux branches verticales se trouvent appliquées sur la toile 17 contre une bande périphérique 42 en élastomère qui est notamment destinée à compenser les éventuels gauchissements des cadres en présence. Furthermore, as shown in FIG. 5, in order to improve the retention of the periphery of the fabric 17 which is pinched between the frames 9 and 15, there is arranged under the frame 9 a profiled element 40 with a U-shaped cross section. , whose two vertical branches are applied to the fabric 17 against a peripheral strip 42 of elastomer which is in particular intended to compensate for any warpage of the frames present.
Dans une variante de mise en oeuvre de l'invention représentée sur les figures 6 et 7, le plateau supérieur 23 est constitué de deux éléments montés à coulissement l'un par rapport à l'autre de l'avant vers l'arrière. Le plateau 23 est ainsi constitué d'une embase 24 qui est solidaire du piston 20 du vérin hydraulique supérieur 19, contre la face inférieure de laquelle sont fixées deux glissières latérales 27 qui supportent un élément 23' qui constitue le plateau destiné à venir en contact avec le cadre 40. La glissière 27 permet à l'élément 23' d'occuper deux positions, à savoir une position centrée et active (ainsi que représenté sur la figure 7) dans laquelle il vient en appui sur le cadre et une seconde position, ou position rétractée vers l'arrière du dispositif, qui permet à l'utilisateur d'avoir un accès facile au cadre support 15 sur lequel il doit disposer la toile 17 destinée à recouvrir le cadre, sans être gêné par la présence du plateau 23. In an alternative embodiment of the invention shown in Figures 6 and 7, the upper plate 23 consists of two elements mounted to slide relative to each other from the front to the rear. The plate 23 thus consists of a base 24 which is integral with the piston 20 of the upper hydraulic cylinder 19, against the underside of which are fixed two lateral slides 27 which support an element 23 'which constitutes the plate intended to come into contact with the frame 40. The slide 27 allows the element 23 'to occupy two positions, namely a centered and active position (as shown in FIG. 7) in which it comes to bear on the frame and a second position , or retracted position towards the rear of the device, which allows the user to have easy access to the support frame 15 on which he must have the canvas 17 intended to cover the frame, without being hampered by the presence of the plate 23 .
Dans un mode de mise en oeuvre de l'invention représenté sur la figure 8, la force de pression avec laquelle le ressort 18 applique le cadre 15 contre le cadre 9 est ajustable. A cet effet le plateau 11 est bordé, sur sa périphérie, d'un élément cornière 12 dont l'aile horizontale est traversée par une vis 14, le ressort 18 venant prendre appui dans une coupelle 16 disposée en extrémité de celle- ci. On comprend dès lors que par un vissage plus ou moins important de la vis 14 dans l'aile 12 on règle l'importance de la force de compression exercée par le ressort 18 sur le cadre support 15.In an embodiment of the invention shown in FIG. 8, the pressure force with which the spring 18 applies the frame 15 against the frame 9 is adjustable. To this end, the plate 11 is bordered, on its periphery, with an angle element 12, the horizontal wing of which is crossed by a screw 14, the spring 18 coming to bear in a cup 16 disposed at the end of the latter. It will therefore be understood that by a more or less significant screwing of the screw 14 in the wing 12, the importance of the compressive force exerted by the spring 18 on the support frame 15 is adjusted.
