Abstract
Description
La présente invention concerne une scie comportant une ou plusieurs lames pour couper des buches et un Qu plusieurs couteaux de séparation qui sont disposés après les lames. The present invention relates to a saw comprising one or more blades for cutting logs and a Qu several separation knives which are arranged after the blades.
On connaît dans l'art des montures de ce type dans lesquelles les guides, lames de scie et couteaux de séparation sont montés de manière fixe dans la scie. Le problème avec une telle réalisation est que l'espace entre les points fixes de guidage travaillant le bois, vus dans la direction de sciage de la bûche, s'agrandissent tellement qu'un sciage en courbe ne devient plus possible. Par conséquent, la ou les lames de scie ne peuvent suivre la sinuosité de l'arbre, et elle(s) sciera(ront) la buche suivant la ligne sur laquelle elles sont fixées. Cela réduit sensiblement le rapport d'utilisation du bois. Mounts of this type are known in the art in which the guides, saw blades and separation knives are fixedly mounted in the saw. The problem with such an embodiment is that the space between the fixed guide points working the wood, seen in the sawing direction of the log, becomes so large that a curved sawing no longer becomes possible. Consequently, the saw blade (s) cannot follow the winding of the tree, and it (s) will saw (ront) the log along the line on which they are fixed. This significantly reduces the wood usage ratio.
L'objet de la présente invention est d'éliminer l'inconvénient cité ci-dessus et de proposer un nouveau type de scie. La scie de la présente invention est caractérisée en ce que les lames de scie et les couteaux de séparation sont situés Aus un enserdble de sciage séparé. qui est relié par articulation au bâti de la scie et suit la sinuosité de la bûche. La liaison articulée de l'ensemble de sciage permet un sciage en courbe même dans le cas de bûches de gros diamètre car, grâce â la liaison articulée, l'espacement des points de guidage fixes dans la direction de sciage est suffisamment court et les lames de scie et le couteau de séparation peuvent mieux suivre la sinuosité de l'arbre pendant le processus de sciage. The object of the present invention is to eliminate the drawback mentioned above and to propose a new type of saw. The saw of the present invention is characterized in that the saw blades and the separation knives are located in a separate saw assembly. which is connected by articulation to the frame of the saw and follows the sinuosity of the log. The articulated connection of the sawing unit allows curved sawing even in the case of large-diameter logs because, thanks to the articulated connection, the spacing of the fixed guide points in the sawing direction is sufficiently short and the blades saw blade and the separation knife can better follow the winding of the tree during the sawing process.
La suite de la description se réfère aux dessins annexés, dans lesquels
la figure 1 représente une bûche entre les lames et guides'de la scie de la présente invention, dans une vue en élévation ;
la figure 2 est identique à la figure 1, avec l'unité de sciage selon un autre mode de réalisation de l'invention.The following description refers to the accompanying drawings, in which
Figure 1 shows a log between the blades and guides of the saw of the present invention, in an elevation view;
Figure 2 is identical to Figure 1, with the sawing unit according to another embodiment of the invention.
La scie selon la présente invention comprend, cette éntniération étant faite dans le sens d'alimentation, des roues de traction montées élastiquement 1, un jeu â autocentrage de rails de guidage 2, des couteaux d'équarrissage 3, 4, pouvant tourner autour d'un axe horizontal et d'un axe vertical, des rouleaux de-guidage 5, et un ensemble de sciage 6. Des lames de scie 7 et des couteaux de séparation 8 sont situés dans l'ensemble de sciage 6, lequel est fixé à un bâti 9 de la scie d'une manière articulée, ce qui permet de suivre la sinuosité de la bûche. The saw according to the present invention comprises, this entneration being made in the feeding direction, elastically mounted traction wheels 1, a self-centering set of guide rails 2, rendering knives 3, 4, which can rotate around a horizontal axis and a vertical axis, guide rollers 5, and a saw assembly 6. Saw blades 7 and separating knives 8 are located in the saw assembly 6, which is fixed to a frame 9 of the saw in an articulated manner, which makes it possible to follow the sinuosity of the log.
Dans le mode de réalisation de la figure 2, l'ensemble de sciage comprend des rouleaux guidage 10 à l'avant des lames de scie 7. Ces rouleau guident l'ensemble de sciage 6 en conformité avec la sinuosité de la bûche 11. L'ensemble de sciage 6 est fixé de manière articulée au bâti 9 de la scie de manière à pouvoir pivoter autour d'un axe horizontal 12, et peut de plus être monté de manière à pouvoir tourner autour d'un axe vertical 13 représenté par un trait mixte en figure 2. In the embodiment of FIG. 2, the sawing assembly comprises guide rollers 10 at the front of the saw blades 7. These rolls guide the sawing assembly 6 in accordance with the winding of the log 11. L the sawing assembly 6 is hingedly attached to the frame 9 of the saw so as to be able to pivot around a horizontal axis 12, and can moreover be mounted so as to be able to rotate around a vertical axis 13 represented by a dashed line in Figure 2.
Grâce à la mobilité de l'ensemble de sciage 6 que permet l'agencement articulé, le sciage en courbe est maintenant effectué avec succès, même dans le cas où l'on emploie des lames de scie circulaire 7 de grand diamètre. Thanks to the mobility of the sawing assembly 6 that allows the articulated arrangement, the curved sawing is now carried out successfully, even in the case where circular saw blades 7 of large diameter are used.
Il apparaîtra à l'homme de l'art que la présente invention est susceptible de variantes et de modifications. Par exemple, le nombre des lames de scie 7 et des couteaux de séparation 8 peut être de 1 ou plus. Selon la linéarité ou la sinuosité de la bûche que l'on scie, la lame 7 et le couteau 8 peuvent, pendant le processus de sciage, être alignés avec les lignes des couteaux 3, 4 équarrissant les côtés de la bûche, comme dans l'exemple précédent,ou être situés sur une ligne différente, c'est-à-dire que le couteau de séparation 8 est monté en pivotement par rapport à la lame de scie 7. It will be apparent to those skilled in the art that the present invention is subject to variations and modifications. For example, the number of saw blades 7 and separating knives 8 can be 1 or more. Depending on the linearity or the sinuosity of the log to be sawed, the blade 7 and the knife 8 can, during the sawing process, be aligned with the lines of the knives 3, 4 squaring the sides of the log, as in 'previous example, or be located on a different line, that is to say that the separating knife 8 is pivotally mounted relative to the saw blade 7.
