Description

La chaîne de roulement, objet du brevet français déposé le 1.9.81 sous le numéro 81 16738, permet, à l'aide de moyens mécaniques simples et fiables, de coller en continu et, notamment, de fabriquer du bois reconstitué par superposition de planches, appelé bois lamellé.The rolling chain, the subject of the French patent filed on 1.9.81 under the number 81 16738, allows, using simple and reliable mechanical means, to bond continuously and, in particular, to make reconstituted wood by superimposing boards , called laminated wood.

La presse continue, réalisée à partir de cette chaîne de roulement, ou par d'autres moyens, n'est utilisable, pour la production de bois lamellé, qu'en combinaison avec le chauffage haute-fréquence, afin d'obtenir un durcissement suffisamment rapide de la colle.The continuous press, produced from this rolling chain, or by other means, can only be used, for the production of laminated wood, in combination with high-frequency heating, in order to obtain a sufficiently hardening. quick glue.

La difficulté d'application d'un tel chauffage, due à l'application nécessaire d'organes isolants, le coût élevé et le mauvais rendement des générateurs, l'hétérogénéité du matériau bois rendant le réglage et le fonctionnement délicats, ont conduit à rechercher de nouveaux moyens, permettant d'éviter l'apport de chaleur dans les plans de collage.The difficulty of applying such a heating, due to the necessary application of insulating members, the high cost and the poor efficiency of the generators, the heterogeneity of the wood material making the adjustment and the operation delicate, led to seek new means, making it possible to avoid the addition of heat in the bonding planes.

Le procédé de collage, objet du brevet français déposé le 1.10.81 sous le numéro 81 18661 et sous le titre de "procédé et dispositif de collage de deux surfaces de bois entre elles", constitue une réponse partielle au problème posé.The bonding process, subject of the French patent filed on 1.10.81 under number 81 18661 and under the title of "process and device for bonding two surfaces of wood between them "constitutes a partial response to the problem posed.

Alors que la molette, dispositif essentiel utilisé pour l'application du procédé précité, convient parfaitement pour la réalisation de micro-sillons dans un plan perpendiculaire à l'axe des fibres du bois, les sillons ne sont pas réalisables par molettage ou impression, parallèlement à celles-ci : l'élasticité des fibres d'une part, et leur fissilité d'autre part, s'y opposent.While the thumbwheel, an essential device used for the application of the aforementioned process, is perfectly suitable for producing micro-grooves in a plane perpendicular to the axis of the wood fibers, the grooves cannot be produced by knurling or printing, in parallel to these: the elasticity of the fibers on the one hand, and their fissility on the other hand, oppose it.

L'objet essentiel de l'invention est basé sur l'obtention d'un autoserrage en réalisant dans les surfaces de bois à assembler, des micro-sillons, par enlèvement partiel ou total de matière, en évitant de solliciter, au-delà de certaines limites, l'élasticité et la fissilité des fibres.The essential object of the invention is based on obtaining a self-tightening by making in the wood surfaces to be assembled, micro-grooves, by partial or total removal of material, avoiding stress, beyond certain limits, elasticity and fissility of the fibers.

Pour obtenir un tel résultat, il est fait usage des possibilités qu'offre la presse continue, celle notamment de transmettre des efforts de translation élevés sur le matériau en compression et véhiculé à travers la machine.To obtain such a result, use is made of the possibilities offered by the continuous press, in particular that of transmitting high translational forces on the material in compression and conveyed through the machine.

Afin de coller deux ou plusieurs pièces de bois entre elles par autoserrage, on munit les surfaces à assembler de microsillons ; on les encolle et on les introduit en les superposant dans une presse continue en les comprimant progressivement entre deux surfaces planes.In order to stick two or more pieces of wood together by self-tightening, the surfaces to be assembled are provided with microgrooves; they are glued and introduced by superimposing them in a continuous press by gradually compressing them between two flat surfaces.

Ce procédé peut être rendu plus performant de la manière suivante :

  • Il a été pris pour base le procédé décrit dans le brevet français déposé le 12.10.81 sous le numéro 81 19288 et ayant pour titre : "Machine pour le débit, sans pertes de matières, de feuilles, planches et madriers à partir d'équarris en bois".
This process can be made more efficient as follows:
  • The process described in the French patent filed on 12.10.81 under number 81 19288 was taken as a basis and having as its title: "Machine for cutting, without loss of materials, sheets, boards and planks from rendered in wood".

Dans une telle machine, un couteau fixe sépare par tranchage du bois massif en compression et translation à l'intérieur d'une presse continue, en deux parties.In such a machine, a fixed knife separates by solid wood cutting in compression and translation inside a continuous press, in two parts.

Pour réaliser les micro-sillons, il a été prévu un dispositif analogue à celui du couteau fixe à l'intérieur de la presse continue, mais dont les fonctions successives sont les suivantes :

  • 1°) Séparer deux planches superposées à l'intérieur de la presse et destinées à être assemblées par collage.
  • 2°) Réaliser sur chaque plan de collage les microsillons à l'aide d'outils, par défilement de ces plans à travers la zone d'action de ces outils.
  • 3°) Couvrir les plans munis de sillons, de colle par défilement de ces plans à travers une zone d'enduction.
  • 4°) Réunir les planches séparées en phase 1, par emboîtage rigoureux des sillons les uns dans les autres.
To make the micro-grooves, a device similar to that of the fixed knife inside the continuous press has been provided, but the successive functions of which are as follows:
  • 1 °) Separate two overlapping boards inside the press and intended to be assembled by gluing.
  • 2 °) Carry out the microgrooves on each bonding plane using tools, by scrolling these plans through the action area of these tools.
  • 3 °) Cover the plans provided with grooves, glue by scrolling these plans through a coating area.
  • 4 °) Bring together the separate planks in phase 1, by rigorous fitting of the grooves into each other.

La presse continue, ces fonctions étant réalisées, exerce ensuite une compression importante sur les planches munies de sillons et enduites de colle, pour qu'un autoserrage efficace assure une pression de contact pour le durcissement de la colle après sortie de ces planches, de la presse.The continuous press, these functions being carried out, then exerts a significant compression on the boards provided with grooves and coated with glue, so that an effective self-tightening ensures a contact pressure for the curing of the glue after leaving these boards, the hurry.

Autoserrés, les bois lamellés en sortie de presse pourront être stockés sous enceinte chauffée ou non, jusqu'à complet durcissement de la colle, avant mise en oeuvre.Self-tightening, the laminated timber at the press outlet can be stored in a heated or unheated enclosure, until the glue has completely hardened, before processing.

L'invention sera mieux comprise à l'aide des dessins annexés, décrivant et illustrant l'un des modes préférentiels de mise en oeuvre du procédé.The invention will be better understood with the aid of the appended drawings, describing and illustrating one of the preferred modes of implementing the method.

La figure 1 de ces dessins est une coupe schématique d'un dispositif mettant en oeuvre le procédé selon l'invention, parallèlement à l'axe de la presse continue.Figure 1 of these drawings is a schematic section of a device implementing the method according to the invention, parallel to the axis of the continuous press.

La figure 2 est une coupe perpendiculaire à l'axe de deux planches réunies par autoserrage.Figure 2 is a section perpendicular to the axis of two boards joined together by self-tightening.

Selon la figure 1, un corps fixe 1 en acier, ayant la forme d'une lentille, est fixé à l'intérieur de la presse continue, de la même manière que le couteau fixe décrit dans le brevet 81 19288.According to Figure 1, a fixed body 1 of steel, having the shape of a lens, is fixed inside the continuous press, in the same way as the knife fixed described in patent 81 19288.

Ce corps 1 remplit 4 fonctions :

  • 1°) Séparer 2 planches entre elles,
  • 2°) Munir les plans à coller de micro-sillons,
  • 3°) Enduire ces plans de colle,
  • 4°) Reserrer les planches en les guidant pour éviter tout glissement latéral.
This body 1 fulfills 4 functions:
  • 1 °) Separate 2 boards between them,
  • 2 °) Equip the planes to be glued with micro-grooves,
  • 3 °) Coat these planes with glue,
  • 4 °) Tighten the boards by guiding them to avoid any lateral sliding.

Un couteau 2 en acier, situé à l'avant du corps 1 contribue à remplir la première fonction, celle de séparer 2 couches de planches.A knife 2 made of steel, located at the front of the body 1 contributes to fulfilling the first function, that of separating 2 layers of boards.

La partie cônique à l'avant du corps 1 est destinée à écarter les planches et à les diriger vers une zone parallèle dans laquelle se trouvent logés les couteaux 3 de façonnage des micro-sillons qui assurent la deuxième fonction du corps 1. La longueur de la partie cônique est fonction de l'épaisseur des planches, le rayon de courbure des planches tolérable et généralement admis étant égal à 160 fois cette épaisseur.The tapered part at the front of the body 1 is intended to spread the boards and direct them towards a parallel zone in which are housed the knives 3 for shaping micro-grooves which ensure the second function of the body 1. The length of the conical part is a function of the thickness of the boards, the tolerable and generally accepted radius of curvature of the boards being equal to 160 times this thickness.

Dans cette zone parallèle, les planches sont fortement comprimées par les tapis articulés de la presse continue non figurés sur le dessin, et plaqués contre les faces parallèles du corps 1. Dans ces faces sont logés des couteaux fixes 3, dont la position est règlable et qui agissent à la manière d'un rabot, l'angle d'attaque de ces couteaux se situant autour de 30 degrés. Le talon des couteaux 3,sur lequel glissent les planches, est muni de sillons ayant la forme de ceux que l'on souhaite appliquer aux planches. Ces couteaux 3 pourront être précédés de couteaux identiques, mais dont le talon possède une surface plane, agissant à la manière d'une lame de rabot, l'épaisseur du copeau étant égale à la valeur du dépassement de la surface du talon par rapport à la surface de glissement du corps 1.In this parallel zone, the boards are strongly compressed by the articulated belts of the continuous press not shown in the drawing, and pressed against the parallel faces of the body 1. In these faces are fixed knives 3, the position of which is adjustable and which act like a plane, the angle of attack of these knives being around 30 degrees. The heel of the knives 3, on which the boards slide, is provided with grooves having the shape of those which it is desired to apply to the boards. These knives 3 may be preceded by identical knives, but the heel of which has a flat surface, acting in the manner of a planer blade, the thickness of the chip being equal to the value of the protrusion of the surface of the heel relative to the sliding surface of the body 1.

Un réglage latéral des couteaux 3 permet de positionner les sillons de telle manière à ce que l'on obtienne, au moment de la jonction des plans encollés, un emboîtage rigoureux de ceux-ci. Des évidements 4, de forme circulaire de préférence, sont prévus pour permettre l'évacuation des copeaux engendrés par les couteaux 3. Dans ces évidements sont logés des moyens mécaniques d'extraction des copeaux, par exemple une vis d'Archimède. Celle-ci extrait les copeaux du corps 1 à travers un hachoir pour obtenir des copeaux fragmentés évacuables pneumatiquement ou par tout autre moyen.A lateral adjustment of the knives 3 makes it possible to position the grooves so that one obtains, at the time of joining the glued planes, a rigorous fitting of these. Recesses 4, preferably of circular shape, are provided to allow the evacuation of the chips generated by the knives 3. In these recesses are housed mechanical means for extracting the chips, for example an Archimedes screw. This extracts the chips from the body 1 through a chopper to obtain fragmented chips that can be removed pneumatically or by any other means.

La troisième fonction du corps 1, qui consiste à enduire les plans de collage, est assurée par un poste d'encollage, constitué par des buses 5 situées derrière les couteaux de profilage et en zone parallèle du corps 1.The third function of the body 1, which consists in coating the bonding planes, is ensured by a gluing station, constituted by nozzles 5 located behind the profiling knives and in the parallel zone of the body 1.

Les buses d'encollage reçoivent la colle par des conduits sous pression munis de vannes commandées par des cellules photoélectriques ou autres moyens électromécaniques, dépendantes de l'avancement des planches 6. Ces buses 5 peuvent être remplacées par des rouleaux encolleurs recevant la colle par des bacs dans lesquels ces rouleaux barbottent. Ils seront munis de préférence de cannelures ayant la forme des sillons.The glue nozzles receive the glue by pressurized conduits fitted with valves controlled by photoelectric cells or other electromechanical means, dependent on the advancement of the boards 6. These nozzles 5 can be replaced by glue rollers receiving the glue by tanks in which these rollers bubble. They will preferably be provided with grooves having the shape of grooves.

La quatrième fonction est assurée par une partie cônique identique à l'avant du corps 1 précédemment décrit. Les faces de glissement du corps 1, situées derrière les couteaux de profilage, sont munies de rainures dans lesquelles viennent s'encastrer les sillons des planches, afin d'éviter tout déplacement latéral de celles-ci, avant encastrement des planches entre elles.The fourth function is provided by a conical part identical to the front of the body 1 previously described. The sliding faces of the body 1, located behind the profiling knives, are provided with grooves in which the grooves of the boards are fitted, in order to avoid any lateral displacement of the latter, before embedding the boards together.

La presse continue comporte, en aval du corps l, une zone de pression suffisante pour l'obtention d'un autoserrage puissant, empêchant tout relachement après la sortie de la presse.The continuous press comprises, downstream of the body 1, a zone of pressure sufficient to obtain a powerful self-tightening, preventing any slackening after the release of the press.

En amont du corps 1, une zone de pression, ayant en général une longueur double de la zone précédemment décrite, transmet aux planches 6 des efforts de translation supérieurs aux efforts de résistance dûs aux surfaces de glissement du corps 1 additionnés des efforts de coupe des couteaux 3.Upstream of the body 1, a pressure zone, generally having a length twice the zone previously described, transmits to the plates 6 transla tion greater than the resistance forces due to the sliding surfaces of the body 1 plus the cutting forces of the knives 3.

La figure 2 montre en coupe deux planches 6 assemblées par micro-sillons. Selon ce dessin, les sillons 7 ont une forme trapézoïdale, le pas étant en général 4 fois supérieur à la hauteur et celle-ci inférieure ou égale à 2 mm. Un angle d'environ 6 degrés des parois assurant l'autoserrage donne des résultats très satisfaisants, cet angle étant inférieur à l'angle de frottement.Figure 2 shows in section two plates 6 assembled by micro-grooves. According to this drawing, the grooves 7 have a trapezoidal shape, the pitch generally being 4 times greater than the height and the latter less than or equal to 2 mm. An angle of about 6 degrees of the walls ensuring self-tightening gives very satisfactory results, this angle being less than the friction angle.

Cette description n'a pas de caractère restrictif, chaque caractéristique pouvant être combinée avec des moyens connus, sans pour autant sortir du champ d'application de l'invention et de son domaine de protection.This description is not restrictive, each characteristic can be combined with known means, without however departing from the scope of the invention and its field of protection.

Le séparateur 2, par exemple, peut ne pas faire l'objet d'un dispositif séparé, le nez du corps 1 ayant la forme d'un couteau et un bord d'attaque apte à séparer les planches.The separator 2, for example, may not be the subject of a separate device, the nose of the body 1 having the shape of a knife and a leading edge capable of separating the boards.

Pour réaliser les sillons, on peut mettre en oeuvre plusieurs outils 3, un premier outil agissant telle une lame de rabot, destiné à aplanir les planches, un second outil réalisant une partie des sillons, un troisième outil assurant la finition.To make the grooves, it is possible to use several tools 3, a first tool acting like a planer blade, intended to flatten the boards, a second tool making part of the grooves, a third tool ensuring the finishing.

Les outils 3 peuvent être remplacés par des outils rotatifs, sans déroger à l'esprit de l'invention. Il en est de même des buses d'encollage 5, dont la fonction peut être effectuée par des rouleaux encolleurs, par exemple, de faible diamètre, munis ou non de cannelures.The tools 3 can be replaced by rotary tools, without departing from the spirit of the invention. The same applies to the glue nozzles 5, the function of which can be carried out by glue rollers, for example, of small diameter, with or without grooves.

Selon les besoins et la nature du bois, les sillons 7 pourront être de forme différente, selon que l'on recherche un autoserrage plus ou moins puissant, une surface de collage importante, ou une économie maximum de bois.Depending on the needs and the nature of the wood, the grooves 7 may be of different shape, depending on whether one is looking for a more or less powerful self-tightening, a large bonding surface, or a maximum economy of wood.

Par la combinaison de la compression en continu et de l'autoserrage, mettant en oeuvre des moyens simples et fiables, de nouvelles perspectives sont offertes à l'industrie du bois, libérant le matériau de ses servitudes dimensionnelles, en augmentant son homogénéité tout en préservant ses qualités mécaniques et esthétiques intrinsèques, et ceci au moindre coût.By the combination of continuous compression and self-tightening, using simple and reliable means, new perspectives are offered to the wood industry, freeing the material from its dimensional constraints, increasing its homogeneity while preserving its intrinsic mechanical and aesthetic qualities, and this at the lowest cost.
