Description
La présente invention concerne le domaine de l'industrie du bois, en particulier la fabrication de mobilier, notamment de caissons, et a pour objet un dispositif de serrage de cadres.The present invention relates to the field of the wood industry, in particular the manufacture of furniture, in particular of boxes, and relates to a device for tightening frames.
Les dispositifs de serrage de cadres existant actuellement sont généralement constitués par un bâti de section rectangulaire à l'intérieur duquel sont montés, avec possibilité de déplacement, au moins un élément vertical de serrage des bords verticaux des cadres à assembler et un élément horizontal de serrage des bords horizontaux des cadres sur le longeron inférieur du bâti (DE-A-1196844).The existing frame clamping devices generally consist of a frame of rectangular section inside which are mounted, with the possibility of displacement, at least one vertical element for clamping the vertical edges of the frames to be assembled and a horizontal clamping element. horizontal edges of the frames on the lower frame member (DE-A-1196844).
Ces dispositifs connus sont, soit du type à réglage manuel, dans lequels au moins un élément vertical sous forme d'un bras mobile peut être immobilisé en position sur les longerons du bâti au moyen de goupilles ou analogues, l'élément horizontal pouvant être réalisé sous forme d'une poutre montée à l'extrémité d'un vérin déplaçable dans le longeron horizontal supérieur et la poutre formant l'élément horizontal étant muni de vérins à action horizontale montés de manière réglable en hauteur sur ladite poutre, le vérin inférieur pouvant éventuellement être monté de manière fixe, soit du type à réglage automatique mécanique, hydraulique ou pneumatique. Les dispositifs de ce dernier type peuvent présenter un ou plusieurs éléments horizontaux déplaçables à partir du longeron horizontal supérieur en direction du longeron horizontal inférieur du bâti au moyen d'un mécanisme du type à croix de Saint-André ou au moyen d'entraînements linéaires agissant sur les extrémités du ou desdits éléments horizontaux. Ces dispositifs peuvent, en outre, également être munis de moyens de serrage des bords verticaux sous forme d'éléments verticaux également déplaçables par rapport aux montants du bâti au moyen d'un mécanisme du type à Croix de Saint-André ou au moyen d'entraînement linéaires agissant sur les extrémités de ces éléments verticaux.These known devices are either of the manual adjustment type, in which at least one vertical element in the form of a movable arm can be immobilized in position on the side members of the frame by means of pins or the like, the horizontal element being able to be produced. in the form of a beam mounted at the end of a cylinder displaceable in the upper horizontal beam and the beam forming the horizontal element being provided with cylinders with horizontal action mounted in an adjustable manner in height on said beam, the lower cylinder being able possibly be fixedly mounted, either of the type with automatic mechanical, hydraulic or pneumatic adjustment. Devices of the latter type may have one or more horizontal elements displaceable from the upper horizontal spar towards the lower horizontal spar of the frame by means of a mechanism of the Saint Andrew cross type or by means of linear drives acting on the ends of the said horizontal element or elements. These devices can, in addition, also be provided with means for clamping the vertical edges in the form of vertical elements. also displaceable with respect to the uprights of the frame by means of a mechanism of the Saint-André cross type or by means of linear drives acting on the ends of these vertical elements.
Ces dispositifs de serrage connus, communément appelés cadreuses, présentent, cependant, l'inconvénient, dans le cas de dispositifs à réglage manuel, de nécessiter un temps de réglage relativement long qui se répercute de manière particulièrement désavantageuse dans le cas de fabrication en petites séries.These known clamping devices, commonly called framing machines, have, however, the drawback, in the case of manual adjustment devices, of requiring a relatively long adjustment time which has a particularly disadvantageous effect in the case of manufacture in small series. .
Les dispositifs de serrage à réglage automatique permettent certes une adaptation rapide des réglages en fonction des cadres à réaliser mais sont, cependant, d'un prix de revient très élevé qui est incompatible avec un petit volume de fabrication.The automatic adjustment clamping devices certainly allow rapid adjustment of the settings according to the frames to be produced, but are, however, of a very high cost price which is incompatible with a small manufacturing volume.
On connaît également, par DE-A-3613742, un dispositif de serrage de cadres présentant des éléments de serrage verticaux déplaçables sur une poutre horizontale et munis de butées empêchant leur basculement, dans une direction, au-delà d'un angle de 90°. Ces éléments de serrage verticaux sont déplaçables par glissement sur leur butée supérieure et peuvent être serrées au moyen de broches. La manoeuvre de ces éléments est toutefois relativement délicate et pénible, leur glissement aisé et précis, en vue du positionnement, sur la poutre horizontale étant difficile à réaliser et nécessitant une dépense musculaire relativement importante. En outre, ces éléments ne permettent pas un serrage rapide de pièces entre eux.Also known from DE-A-3613742 is a frame clamping device having vertical clamping elements displaceable on a horizontal beam and provided with stops preventing their tilting, in one direction, beyond an angle of 90 °. . These vertical clamping elements are movable by sliding on their upper stop and can be tightened by means of pins. The operation of these elements is however relatively delicate and painful, their easy and precise sliding, with a view to positioning, on the horizontal beam being difficult to perform and requiring relatively large muscular expenditure. In addition, these elements do not allow rapid clamping of parts together.
La présente invention a pour but de pallier ces inconvénients.The present invention aims to overcome these drawbacks.
Elle a, en effet, pour objet un dispositif de serrage de cadres, constitué par un bâti de réception des cadres, par un moyen de serrage des bords horizontaux desdits cadres et par un moyen de serrage des bords verticaux des cadres constitué par un bras monté de manière mobile sur le longeron supérieur du bâti et pourvu d'un dispositif de blocage en position de service, caractérisé en ce que le dispositif agit par arc-boutement et est constitué par deux butées montées, l'une sur la face du bras tournée vers le cadre, au-dessus du longeron supérieur du bâti et l'autre sur la face opposée du bras en-dessous du longeron supérieur du bâti, en ce que le bras formant le moyen de serrage des bords verticaux des cadres est solidaire d'un châssis de roulement sur le longeron équipé de deux galets à gorge dont les joues entourent le longeron, ledit châssis étant constitué, d'une part, par un élément horizontal solidaire de l'extrémité supérieure du bras et portant les galets et, d'autre part, par un tirant reliant l'extrémité libre de l'élément au bras, sensiblement dans sa moitié inférieure, et en ce que les galets du châssis de roulement sont montés sur l'élément horizontal de ce dernier avec un décalage en hauteur de leurs axes, l'axe du galet le plus éloigné du bras étant disposé à un niveau plus élevé sur l'élément que l'axe du galet le plus proche du bras et les butées sont disposées sur le bras avec un écartement correspondant à la hauteur du longeron, en position de service du bras, le galet le plus proche du bras étant légèrement soulevé du longeron dans cette dite position de service.It has, in fact, for its object a clamping device for frames, constituted by a frame for receiving the frames, by a means for clamping the horizontal edges of said frames and by a means for clamping the vertical edges of the frames constituted by a mounted arm movably on the upper side member of the frame and provided with a locking device in the operating position, characterized in that the device acts by bracing and is constituted by two stops mounted, one on the face of the turned arm towards the frame, above the upper side member of the frame and the other on the opposite side of the arm below the upper side member of the frame, in that the arm forming the means for tightening the vertical edges of the frames is integral with a rolling chassis on the spar equipped with two grooved rollers whose cheeks surround the spar, said chassis being constituted, on the one hand, by a horizontal element integral with the upper end of the arm and carrying the the rollers and, on the other hand, by a tie connecting the free end of the element to the arm, substantially in its lower half, and in that the rollers of the rolling chassis are mounted on the horizontal element of the latter with an offset in height of their axes, the axis of the roller furthest from the arm being disposed at a higher level on the element that the axis of the roller closest to the arm and the stops are arranged on the arm with a spacing corresponding to the height of the spar, in the service position of the arm, the roller closest to the arm being slightly raised from the spar in this so-called service position.
L'invention sera mieux comprise grâce à la description ci-après, qui se rapporte à un mode de réalisation préféré, donné à titre d'exemple non limitatif, et expliqué avec référence aux dessins schématiques annexés, dans lesquels:
- la figure 1 est une vue en élévation latérale d'un dispositif conforme à l'invention, en position de service;
- la figure 2 est une vue partielle correspondant à la figure 1 représentant le moyen de serrage des bords verticaux en position de repos et de déplacement sur le longeron supérieur du bâti, et
- la figure 3 est une vue partielle, à plus grande échelle, correspondant à celle de la figure 2, représentant le dispositif de blocage en position de service.
- Figure 1 is a side elevational view of a device according to the invention, in the service position;
- Figure 2 is a partial view corresponding to Figure 1 showing the clamping means of vertical edges in the rest and displacement position on the upper side member of the frame, and
- Figure 3 is a partial view, on a larger scale, corresponding to that of Figure 2, showing the locking device in the service position.
Conformément à ce mode de réalisation de l'invention et comme le montre plus particulièrement, à titre d'exemple, la figure 1 des dessins annexés, le dispositif de serrage de cadres 1 qui est constitué par un bâti 2 de réception des cadres 1, par un moyen 3 de serrage des bords horizontaux desdits cadres 1 et par un moyen 4 de serrage des bords verticaux des cadres 1, qui 1 est constitué par un bras monté de manière mobile sur le longeron supérieur 5 du bâti 2 et pourvu d'un dispositif 6 de blocage en position de service par arc-boutement.In accordance with this embodiment of the invention and as shown more particularly, by way of example, FIG. 1 of the accompanying drawings, the frame clamping device 1 which is constituted by a
Le dispositif 6 de blocage en position de service par arc-boutement est avantageusement constitué par deux butées 6′ et 6˝ montées, l'une, 6′, sur la face du bras 4 tourné vers le cadre 1, au-dessus du longeron supérieur 5 du bâti 2 et l'autre, 6˝, sur la face opposée du bras 4 en-dessous du longeron supérieur 5 du bâti 2.The
Le bras 4 formant le moyen de serrage des bords verticaux des cadres 1 est solidaire d'un châssis de roulement sur le longeron 5 équipé de deux galets à gorge 7 dont les joues entourent le longeron 5, ledit châssis étant constitué, d'une part, par un élément horizontal 8 solidaire de l'extrémité supérieure du bras 4 et portant les galets 7 et, d'autre part, par un tirant 9 reliant l'extrémité libre de l'élément 8 au bras 4 sensiblement dans sa moitié inférieure.The
Les galets 7 du châssis de roulement sont avantageusement montés sur l'élément horizontal 8 de ce dernier avec un décalage en hauteur de leurs axes, l'axe du galet 7 le plus éloigné du bras 4 étant disposé à un niveau plus élevé sur l'élément 8 que l'axe du galet 7 le plus proche du bras 4 et les butées 6′ et 6˝ sont disposées sur le bras 4 avec un écartement correspondant à la hauteur du longeron 5, en position de service du bras 4, le galet 7 le plus proche du bras 4 étant légèrement soulevé du longeron 5 dans cette dite position de service. Ainsi, en position de non-utilisation du bras 4, ce dernier est légèrement incliné par rapport à la verticale, en direction du cadre à serrer, les deux galets 7 de son châssis de roulement reposant sur le longeron 5 et les butées 6′ et 6˝ présentant chacune un jeu avec la face correspondante dudit longeron 5. En effet, l'écartement entre les faces opposées des butées 6′ et 6˝ étant égal à la hauteur du longeron 5 en position de serrage d'un cadre 1 par arc-boutement, c'est-à-dire les butées 6′ et 6˝ s'appuyant chacune par une face sur ledit longeron 5 et le galet 7 le plus éloigné du bras 4 étant soulevé du longeron 5, le galet 7 le plus proche du bras 4 étant légèrement soulevé du longeron 5, lors du retour du bras 4 en position de non-utilisation, il s'effectue un pivotement de l'ensemble bras 4 et châssis de roulement autour de l'axe du galet 7 le plus proche du bras 4, après son appui sur le longeron 5, ayant pour effet d'écarter lesdites butées 6′ et 6˝ de leur point d'appui sur le longeron 5.The
De manière connue, le bras 4 est pourvu à son extrémité libre d'un vérin 10 d'appui sur le bord de la partie inférieure du cadre 1 à serrer et le moyen 3 de serrage des bords horizontaux des cadres 1 est constitué par un ou plusieurs vérins 12 à action verticale, dont la tige de piston s'appuie par l'intermédiaire d'une barre horizontale 13 sur les bords supérieurs desdits cadres 1.In known manner, the
Le bras 4 peut être muni d'un ou de plusieurs vérins 11, mobiles verticalement, de serrage des bords verticaux du cadre 1, le déplacement de ces vérins 11 étant réalisé au moyen d'autres vérins à déplacement vertical, ou par réglage manuel. Ainsi, il est possible d'adapter les vérins de serrage vertical aux dimensions verticales des cadres 1 à serrer.The
La mise en oeuvre du dispositif conforme à l'invention s'effectue par simple déplacement du bras 4 ensemble avec son châssis de roulement sur le longeron 5 du bâti 2 en direction du cadre 1 à serrer jusqu'à arrivée en butée du vérin 10, équipant l'extrémité libre du bras 4, contre la partie inférieure du côté vertical du cadre 1. Sous l'effet de l'inertie de l'ensemble bras 4 et châssis de roulement, est réalisé un arc-boutement du bras 4 sur les butées 6′ et 6˝. L'effet d'arc boutement obtenu est augmenté lors de la mise sous pression du vérin 10 et du ou des vérins 11, la force de serrage exercée par ces derniers ayant pour résultante un couple théorique de pivotement autour des butées 6′ et 6˝ et augmentant en conséquence leur force d'appui sur les faces correspondantes du longeron 5.The device according to the invention is implemented by simply moving the
Selon une variante de réalisation de l'invention, non représentée aux dessins annexés, le bras 4 ou son châssis de roulement peut être muni d'un dispositif de commande de déplacement sous forme d'un vérin dont l'arrêt est commandé par un palpeur situé à proximité du vérin 10 équipant l'extrémité libre du bras 4. Dans ce mode de réalisation, il suffit à l'opérateur de commander l'actionnement du vérin de déplacement du bras 4, le déclenchement de ce vérin s'effectuant automatiquement lors de la mise en butée du vérin 10 contre le cadre 1 à serrer. Il est ainsi possible à l'opérateur d'effectuer une manipulation éventuelle à deux mains avant la mise en butée du bras 4.According to an alternative embodiment of the invention, not shown in the accompanying drawings, the
Le dispositif conforme à l'invention permet de réaliser rapidement et de manière efficace un serrage des bords verticaux de cadres à assembler et une adaptation instantanée du moyen de serrage des bords verticaux des cadres aux dimensions de ces derniers.The device according to the invention makes it possible to quickly and effectively tighten the vertical edges of frames to be assembled and to adapt them instant of the means for clamping the vertical edges of the frames to the dimensions of the latter.
Grâce à l'invention, il est possible de réaliser un dispositif de serrage de cadres de constitution simple, de faible prix de revient et pouvant facilement être mis en oeuvre.Thanks to the invention, it is possible to produce a clamping device for frames of simple construction, of low cost price and which can easily be implemented.
Bien entendu, l'invention n'est pas limitée au mode de réalisation décrit et représenté aux dessins annexés. Des modifications restent possibles, notamment du point de vue de la constitution des divers éléments ou par substitution d'équivalents techniques, sans sortir pour autant du domaine de protection de l'invention selon la revendication 1.Of course, the invention is not limited to the embodiment described and shown in the accompanying drawings. Modifications remain possible, in particular from the point of view of the constitution of the various elements or by substitution of technical equivalents, without thereby departing from the scope of protection of the invention according to claim 1.
