Abstract

The edges of the surface of the planks (1) receive a quantity of glue greater than the remainder of the surface. An additional fillet 18 is deposited on each side of the plank (1) which moves past under a curtain of glue fillets. The additional fillets are deposited by a device (14) which follows the edge of the plank (1) so as to adapt to the width or to the position of the latter. Gaps in the glue on the lateral faces of the beams are avoided while the glue is sparingly used. <IMAGE>

Description

La présente invention a pour objet un perfectionnement aux procédés et dispositifs d'encollage de planches de bois en vue de la fabrication d'assemblages dénommés lamellé-collé.The present invention relates to an improvement to the methods and devices for gluing wooden planks for the manufacture of assemblies called glulam.

Pour assurer le collage d'une planche contre une autre, on dépose de la colle sur la face de contact d'au moins une des deux planches, de préférence sous forme de filets parallèles équidistants, qui sont réalisés par des jets qui se déversent sur une planche qui défile en dessous. Comme on a à traiter des planches de largeurs différentes, pour éviter des réglages fréquents des machines, les jets forment un rideau de grande largeur, supérieure à la largeur des planches en défilement, de sorte que toutes les planches passant par l'installation reçoivent de la colle sur toute leur largeur, quelqu'elle soit. La colle qui est déversée en dehors de la largeur d'une planche en défilement tombe dans un bac de récupération placé en dessous, d'oû elle est renvoyée dans la pompe de l'installation.To ensure the bonding of one board against another, glue is deposited on the contact face of at least one of the two boards, preferably in the form of equidistant parallel threads, which are produced by jets which flow onto a board that scrolls below. As we have to deal with boards of different widths, to avoid frequent adjustments of the machines, the jets form a curtain of great width, greater than the width of the boards in movement, so that all the boards passing through the installation receive glue over their entire width, whatever it is. The glue which is poured outside the width of a moving board falls into a collecting tank placed below, from where it is returned to the installation pump.

Une planche ainsi traitée se présente alors comme représenté sur la figure 1 où l'on voit une planche 1 garnie de filets de colle 2. Tout cela va bien tant que les planches sont bien comme prévu, c'est-à-dire avec une épaisseur constante et bien plane. Or, il peut arriver que par suite du temps de transport et de stockage, la planche présente un défaut et soit déformée. Elle peut se galber et/ou se rétrécir sur les bords par suite de sécheresse, comme représenté en coupe en 3 sur la figure 2. On obtient alors des assemblages de lamellé-collé dont le bord présente des défauts comme le défaut 4 sur la figure 3. Quand on s'en aperçoit, l'assemblage entier risque d'être mis en rebus.A board thus treated is then presented as shown in FIG. 1 where we see a board 1 furnished with glue threads 2. All this is fine as long as the boards are as expected, that is to say with a constant thickness and flat. However, it may happen that as a result of the transport and storage time, the board has a defect and is deformed. It can curve and / or shrink at the edges as a result of dryness, as shown in section in 3 in FIG. 2. We then obtain glue-laminated assemblies whose edge has defects like defect 4 in Figure 3. When you notice, the entire assembly may be discarded.

La présente invention a pour but d'éviter ces inconvénients.The present invention aims to avoid these drawbacks.

Par conséquent, la présente invention a pour objet un procédé d'encollage de planches de bois en vue de la fabrication d'assemblages dénommés lamellé-collé, caractérisé en ce que les bords de la surface de la planche reçoivent une quantité de colle supérieure au reste de la surface. En général, la surface supérieure de la planche reçoit des filets de colle régulièrement espacés, et, selon la présente invention, un filet supplémentaire est déposé de chaque côté de la planche, à une petite distance du bord latéral de la planche. Le filet supplémentaire peut être plus gros que les autres.Consequently, the subject of the present invention is a method of gluing wooden planks for the manufacture of assemblies called glulam, characterized in that the edges of the surface of the plank receive a quantity of glue greater than the rest of the surface. In general, the upper surface of the board receives regularly spaced glue threads, and, according to the present invention, an additional thread is deposited on each side of the board, a short distance from the side edge of the board. The additional net may be larger than the others.

L'invention a aussi pour objet un dispositif pour la mise en oeuvre de ce procédé, comportant des moyens pour faire défiler à plat une planche de bois au dessus d'un bac de récupération et des moyens pour déverser sur la planche, pendant son déplacement, une couche de colle, de préférence sous forme d'une série de filets équidistants, lesdits moyens étant prévus pour déverser la colle sur une largeur supérieure à celle de la planche de façon que la colle déversée en dehors de la largeur de la planche tombe dans le bac de récupération, caractérisé en ce qu'il comporte des moyens adaptés à suivre au moins un bord de la planche pour déposer de la colle dans la région dudit au moins un bord.The invention also relates to a device for implementing this method, comprising means for scrolling flat on a wooden board above a recovery tank and means for pouring onto the board, during its displacement, a layer of glue, preferably in the form of a series of equidistant nets, said means being provided for pouring the glue over a width greater than that of the board so that the glue spilled outside the width of the board falls into the recovery tank, characterized in that it comprises means adapted to follow at least one edge of the board for depositing glue in the region of said at least one edge.

Dans une forme de réalisation avantageuse de l'invention, lesdits moyens adaptés à suivre au moins un bord de la planche comportent un suiveur sollicité élastiquement contre le bord de la planche, de façon à rester au contact du bord quelques soient la largeur et la position de la planche, des moyens de déversement étant fixés audit suiveur pour déverser un filet de colle à une distance déterminée de l'extrémité dudit suiveur qui est maintenue au contact du bord de la planche.In an advantageous embodiment of the invention, said means adapted to follow at least one edge of the board comprise a follower elastically urged against the edge of the board, so as to remain in contact with the edge whatever the width and the position of the board, pouring means being fixed to said follower for pouring a thread of glue at a determined distance from the end of said follower which is kept in contact with the edge of the board.

D'autres caractéristiques et avantages de l'invention apparaîtront au cours de la description qui va suivre, donnée à titre d'exemple non limitatif, en regard des dessins ci-joints, et qui fera bien comprendre comment l'invention peut être réalisée.Other characteristics and advantages of the invention will appear during the description which follows, given by way of nonlimiting example, with reference to the attached drawings, and which will make it clear how the invention can be implemented.

Sur les dessins,

  • la figure 1 est une vue en perspective avec coupe d'une planche garnie de colle selon un procédé classique,
  • la figure 2 est une vue en coupe d'une planche présentant un défaut,
  • la figure 3 est une vue en coupe du bord d'un assemblage de planches présentant un défaut, et
  • la figure 4 est une vue en perspective schématique d'un dispositif pour la mise en oeuvre du procédé selon la présente invention.
In the drawings,
  • FIG. 1 is a perspective view, in section, of a board filled with glue according to a conventional method,
  • FIG. 2 is a sectional view of a board having a defect,
  • FIG. 3 is a sectional view of the edge of an assembly of boards having a defect, and
  • Figure 4 is a schematic perspective view of a device for implementing the method according to the present invention.

Sur la figure 1, la planche 1 a été garnie de filets de colle 2. Cela est avantageusement réalisé dans une installation qui est traversée par une planche en mouvement passant à plat. L'installation comporte de façon connue une rampe déversant un rideau de filets de colle, sous lequel passe la planche à plat. Elle est ainsi garnie d'une série de filets ou cordons parallèles longitudinaux, qui permettent le collage pour l'assemblage. Pour pouvoir passer les planches de différentes largeurs sans avoir à faire de réglage, la longueur de la rampe est au moins égale aux plus larges planches à traiter. Donc en général, de la colle est déversée de part et d'autre de la planche et tombe dans un bac de récupération d'où elle est recyclée. Au cours du transport ou de l'entreposage, les planches peuvent se déformer et présenter des défauts comme en 3 sur la figure 2 : par séchage, les zones marginales de la planche peuvent être plus minces ou déformées. On a constaté selon l'invention qu'en mettant une surépaisseur de colle sur les rives des planches, le produit final était correct et ne présentait pas le défaut de petites crevasses comme en 4 sur la figure 3. Avantageusement, on dépose au voisinage du bord de la planche un cordon de colle qui peut être plus épais que les autres.In FIG. 1, the board 1 has been filled with glue threads 2. This is advantageously carried out in an installation which is crossed by a moving board passing flat. The installation comprises, in a known manner, a ramp discharging a curtain of glue threads, under which the flat board passes. It is thus furnished with a series of parallel longitudinal threads or cords, which allow gluing for assembly. To be able to pass the planks of different widths without having to make any adjustments, the length of the ramp is at least equal to the largest planks to be treated. So in general, glue is poured on either side of the board and falls into a collecting container from where it is recycled. During transport or storage, the boards can deform and have defects as in 3 in Figure 2: by drying, the marginal areas of the board can be thinner or deformed. It was found according to the invention that by putting an extra thickness of glue on the edges of the boards, the final product was correct and did not have the defect of small crevices as in 4 in FIG. 3. Advantageously, a bead of adhesive is deposited in the vicinity of the edge of the board, which may be thicker than the others.

Le dispositif représenté sur la figure 4 permet de déposer un cordon de colle à proximité d'un bord de la planche, à la distance que l'on désire, quelque soit la largeur de la planche.The device shown in Figure 4 allows to deposit a bead of glue near an edge of the board, at the distance you want, whatever the width of the board.

Une planche 1 défile à plat dans le sens de la flèche f dans une machine non représentée, pour recevoir sur sa face supérieure une couche de colle, éventuellement sous forme de cordons parallèles équidistants. En un point fixe 10 est articulé par une de ses extrémités un suiveur 11 comportant, au voisinage de son autre extrémité 11a, une face plane ou arrondie 12 sollicitée par un ressort 13 contre la face latérale 14 du bord de la planche 1. En un point du suiveur 11, avantageusement voisin de l'extrémité 11a, est fixée une patte ou un support quelconque 15 auquel est fixé un tube 16 de diamètre et longueur appropriés, alimenté en colle par un flexible 17, pour déposer un filet ou cordon de colle 18 sur le bord de la planche 1. La distance du cordon 18 au bord 14 de la planche ne dépend ni de la largeur de la planche, ni de sa position dans la machine. Cette distance est déterminée par la position du tube 16 sur le support 15. Elle peut être fixe ou réglable. L'orifice du tube 16 ou la pression de la colle peuvent être réglables pour déterminer l'épaisseur du cordon de colle.A board 1 runs flat in the direction of arrow f in a machine not shown, to receive on its upper face a layer of glue, possibly in the form of equidistant parallel cords. At a fixed point 10 is articulated by one of its ends a follower 11 comprising, in the vicinity of its other end 11a, a flat or rounded face 12 biased by a spring 13 against the lateral face 14 of the edge of the board 1. In a point of the follower 11, advantageously close to the end 11a, is fixed a tab or any support 15 to which is fixed a tube 16 of appropriate diameter and length, supplied with glue by a flexible 17, for depositing a net or bead of glue 18 on the edge of the board 1. The distance from the cord 18 to the edge 14 of the board does not depend on the width of the board, nor on its position in the machine. This distance is determined by the position of the tube 16 on the support 15. It can be fixed or adjustable. The hole of the tube 16 or the pressure of the adhesive can be adjustable to determine the thickness of the bead of adhesive.

Le dépôt de colle en supplément sur les bords de la planche permet de limiter la quantité de colle sur le reste de la planche à ce qui est réellement nécessaire, donc d'améliorer la qualité du produit fini, en réalisant une économie sensible de colle.The deposit of additional glue on the edges of the board makes it possible to limit the quantity of glue on the rest of the board to what is really necessary, therefore to improve the quality of the finished product, by achieving a significant economy of glue.

L'absence de fente dans le produit fini a aussi pour conséquence une usure réduite des fers de raboteuse lors de la mise au net de la poutre en lamellé-collé.The absence of a slit in the finished product also results in reduced wear of the planer irons when the glued laminated beam is neat.

L'invention n'est pas limitée par l'exemple ci-dessus et sa portée est définie par les revendications ci-après.The invention is not limited by the above example and its scope is defined by the claims below.
