Description

La présente invention concerne une installation de traitement des dosses en vue de leur valorisation.The present invention relates to an installation for processing the files for their recovery.

On appelle "dosse" la pièce de bois que l'on détache lorsqu'on lave une grume au début du sciage.The piece of wood which is detached when washing a log at the start of sawing is called "dosing".

Les dosses présentent une face plane dressée à la scie et le reste de la surface, appelé le dos, est un segment de la grume.The backs have a flat face erected with a saw and the rest of the surface, called the back, is a segment of the log.

Les dosses ont évidemment une forme et des dimensions irrégulières qui les rendent inexploitables, si ce n'est pour fabriquer du charbon de bois ou, après un retraitement coûteux, de petites liteaux.The backings obviously have an irregular shape and dimensions which make them unusable, except for making charcoal or, after costly reprocessing, small strips.

La présente invention se propose de valoriser les dosses en réalisant, de façon économique, à partir de ces dernières, de nouveaux produits de forme et de dimensions standardisées.The present invention proposes to enhance the backing by making, economically, from the latter, new products of standardized shape and dimensions.

Ce but est atteint par l'invention en ce sens qu'elle apporte une installation de traitement qui comporte, d'une manière connue en soi, des moyens convoyeurs adaptés à recevoir, à acheminer et à évacuer les dosses avant, pendant et après traitement, des moyens presseurs appliquant la face plane des dosses contre les moyens convoyeurs, et des moyens de coupe susceptibles d'agir sur le dos des dosses.This object is achieved by the invention in the sense that it provides a treatment installation which comprises, in a manner known per se, conveyor means adapted to receive, route and evacuate the slabs before, during and after treatment. , pressing means applying the flat face of the backing against the conveyor means, and cutting means capable of acting on the back of the backing.

L'installation se caractérise en ce qu'elle comprend des premiers moyens de coupe situés de part et d'autre des moyens convoyeurs, au voisinage de leur extrémité de réception, lesquels premiers moyens de coupe sont adaptés à prédéligner les dosses pour créer des surfaces de référence, et des seconds moyens de coupe montés sur la face interne d'un rotor creux que traverse le convoyeur, en aval des premiers moyens de coupe, vu dans le sens de convoyage, lesdits seconds moyens de coupe étant adaptés à donner une surface convexe normalisée au dos des dosses prédélignées.The installation is characterized in that it comprises first cutting means located on either side of the conveyor means, in the vicinity of their receiving end, which first cutting means are adapted to pre-align the slabs to create surfaces reference, and second cutting means mounted on the internal face of a hollow rotor through which the conveyor passes, downstream of the first cutting means, seen in the conveying direction, said second cutting means being adapted to give a surface standard convex on the back of the pre-aligned backs.

Grâce à cette structure, on obtient un produit présentant une surface plane et une surface convexe réunies entre elles par des tranches planes.Thanks to this structure, a product is obtained which has a flat surface and a convex surface joined together by flat sections.

Les premiers moyens de coupe peuvent être constitués par des fraises.The first cutting means can consist of strawberries.

Les seconds moyens de coupe peuvent également être constitués par des fraises ou par des couteaux fixes selon la dureté du bois traité.The second cutting means can also be constituted by cutters or by fixed knives depending on the hardness of the treated wood.

Les moyens presseurs sont avantageusement constitués, en amount du rotor, vu dans le sens de convoyage des dosses, de cylindres à périphérie crantée qui agissent sur les dosses avant traitement et, en aval du rotor, de cylindres à périphérie concave qui agissent sur les dosses après traitement.The pressing means are advantageously made up, in the amount of the rotor, seen in the direction of conveying the slabs, of cylinders with notched periphery which act on the slabs before treatment and, downstream of the rotor, of cylinders with concave periphery which act on the slabs after treatment.

Si les tranches des dosses traitées peuvent être planes comme on l'a dit plus haut, elles peuvent également comporter des reliefs mâles et/ou femelles permettant leur réunion emboîtée côte à côte.If the slices of the treated slabs can be flat as mentioned above, they can also include male and / or female reliefs allowing them to be nested side by side.

A cet effet, l'installation comporte, en aval du rotor, vu dans le sens de convoyage des dosses, des moyens de bouvetage appropriés.To this end, the installation comprises, downstream of the rotor, seen in the direction of conveying the slabs, appropriate means of tipping.

L'invention sera mieux comprise à la lecture de la description ci-après faite en référence aux dessins annexés dans lesquels :

  • - la figure 1 est une vue schématique en élévation de l'installation selon l'invention,
  • - les figures 2a et 2b représentent, en perspective, des portions de dosses avant et après traitement, et
  • - la figure 3 est une coupe du rotor prise le long de la ligne III-III de la figure 1.
The invention will be better understood on reading the description below made with reference to the accompanying drawings in which:
  • FIG. 1 is a diagrammatic elevation view of the installation according to the invention,
  • FIGS. 2a and 2b represent, in perspective, portions of backing pieces before and after treatment, and
  • - Figure 3 is a section of the rotor taken along line III-III of Figure 1.

Si l'on se reporte à la figure 1, on voit que l'instal­lation comporte un bâti 1 supportant un convoyeur sans fin 2 entraîné, par l'intermédiaire d'une courroie 3, par une moteur 4. Le convoyeur 2 comporte une extrémité de réception 5 et une extrémité d'évacuation 6, de sorte que les dosses sont convoyées dans le sens indiqué par les flèches F.If we refer to Figure 1, we see that the installation includes a frame 1 supporting an endless conveyor 2 driven, by means of a belt 3, by a motor 4. The conveyor 2 has one end 5 and a discharge end 6, so that the slabs are conveyed in the direction indicated by the arrows F.

Au voisinage de l'extrémité de réception 5, il est prévu une paire de fraises d'entrée 19 adaptées à prédéli­gner les dosses.In the vicinity of the receiving end 5, there is provided a pair of entry cutters 19 adapted to pre-align the records.

Le bâti 1 supporte en outre des moyens hydrauliques ou pneumatiques 7 adaptés à appliquer des cylindres presseurs crantés 8a et 8b sur les dosses reposant sur le convoyeur 2.The frame 1 also supports hydraulic or pneumatic means 7 adapted to apply notched pressure cylinders 8a and 8b on the slabs resting on the conveyor 2.

Comme il ressort en outre de la figure 1, le convoyeur 2 traverse un rotor désigné dans son ensemble par 9, entraîné en rotation par une moteur 10, par l'intermédiaire de courroies 11.As further emerges from FIG. 1, the conveyor 2 passes through a rotor designated as a whole by 9, driven in rotation by a motor 10, by means of belts 11.

La structure du rotor ressort plus clairement de la figure 2 où l'on voit que sa face interne est garnie de fraises 12 ou de couteaux fixes 13, le choix entre fraises et couteaux fixes étant dicté par la dureté du bois traité.The structure of the rotor emerges more clearly from FIG. 2 where it can be seen that its internal face is furnished with milling cutters 12 or fixed knives 13, the choice between milling cutters and fixed knives being dictated by the hardness of the treated wood.

En aval du rotor 9, est prévu un couple de cylindres presseurs 14a et 14b dont la périphérie concave correspond, en courbure, à la convexité conférée aux dosses par les organes de coupe du rotor 9.Downstream of the rotor 9, a pair of pressing cylinders 14a and 14b is provided, the concave periphery of which corresponds, in curvature, to the convexity imparted to the backings by the cutting members of the rotor 9.

Entre les cylindres presseurs à périphérie concave 14a et 14b, sont situés des moyens de bouvetage 15 entraînés par un moteur 16 et adaptés à créer une rainure et une languette sur les tranches opposées de la dosse traitée.Between the pressing cylinders with a concave periphery 14a and 14b, there are located means of tipping 15 driven by a motor 16 and adapted to create a groove and a tongue on the opposite edges of the treated portion.

Le fonctionnement de l'installation est le suivant.The operation of the installation is as follows.

Au départ, la dosse est telle que représentée à la figure 2a, c'est-à-dire qu'elle présente une surface plane 17 et un dos irrégulier 18 grossièrement convexe.At the outset, the dosage is as shown in FIG. 2a, that is to say that it has a flat surface 17 and an irregularly roughly convex back 18.

La première étape consiste à créer des surfaces de référence telles que A, B, C, D de chaque côté de la dosse pour assurer un guidage et un centrage convenables de la pièce de bois dans le rotor. Cette création des surfaces de référence et réalisée à l'aide des fraises d'entrée 19. Les organes de coupe 12 ou 13 du rotor créent ensuite la surface convexe normalisée 20 du produit fini tel qu'il est représenté à la figure 2b. Ensuite, les moyens de bouvetage 15 forment dans les surfaces de référence A, B, C, D, respectivement, une languette 21 et une rainure 22.The first step is to create reference surfaces such as A, B, C, D on each side of the backing to ensure proper guidance and centering of the piece of wood in the rotor. This creation of the reference surfaces and carried out using the input cutters 19. The cutting members 12 or 13 of the rotor then create the standardized convex surface 20 of the finished product as shown in FIG. 2b. Then, the planing means 15 form in the reference surfaces A, B, C, D, respectively, a tongue 21 and a groove 22.

Le produit fini est susceptible d'être utilisé comme lambris intérieur, comme garniture extérieure d'abri de jardin (son aspect bombé rappelant celui des rondins), comme bardage de chantiers pour les bois de mauvaise qualité (par exemple lorsqu'il s'agit de l'aubier du chêne), la configu­ration ondulée des parois résultantes décourageant l'affi­chage.The finished product is likely to be used as interior paneling, as exterior trim for garden sheds (its rounded appearance reminiscent of that of logs), as cladding of construction sites for poor quality wood (for example when it is of the sapwood of the oak), the undulating configuration of the resulting walls discouraging the display.

Le produit selon l'invention peut être également utilisé pour la fabrication d'emballages.The product according to the invention can also be used for the manufacture of packaging.

On notera que, par suite du travail transversal qui est effectué sur les pièces de bois, de longues veines sont découvertes, ce qui donne au produit un aspect particulier exploitable en décoration.It will be noted that, as a result of the transverse work which is carried out on the pieces of wood, long veins are discovered, which gives the product a particular aspect which can be used in decoration.

Il est bien entendu que le produit fini n'a pas nécessairement une languette 21 et une rainure 22. Il pourrait présenter une languette de chaque côté, ou une rainure de chaque côté, les différentes pièces étant réunies ensemble par des pièces intermédiaires de profil complémen­taire. En variante, les surfaces de référence A, B, C, D pourraient être conservées telles quelles sans autre usinage et le produit résultant serait assemblé par clouage ou tout autre moyen approprié.It is understood that the finished product does not necessarily have a tongue 21 and a groove 22. It could have a tongue on each side, or a groove on each side, the different parts being joined together by intermediate parts of complementary profile. . Alternatively, the reference surfaces A, B, C, D could be kept as they are without further machining and the resulting product would be assembled by nailing or any other suitable means.
