Abstract
Description
La présente invention concerne une scie circulaire de long, pour la découpe de matériau en plaques ou panneaux placé dans un plan sensiblement horizontal. The present invention relates to a long circular saw, for cutting material into plates or panels placed in a substantially horizontal plane.
Une scie circulaire de long de ce type est dé cité, par exemple, dans CH-PS 522 483. Elle représente l'une des nombreuses tentatives de réalisation d'une scie circulaire utilisable, fonctionnant automatiquement dans une large mesure et avec une grande productivité. A circular saw of this type is mentioned, for example, in CH-PS 522 483. It represents one of the many attempts to make a usable circular saw, operating automatically to a large extent and with high productivity. .
L'invention a pour objet de réaliser une scie circulaire de long de ce type, qui ait une capacité productive beaucoup plus élevée, qui satisfasse à toutes les conditions, cWest-à-dire soit d'un fonctionnement sûr, tout en étant d'un coût de revient réduit. The object of the invention is to produce a long circular saw of this type, which has a much higher productive capacity, which satisfies all the conditions, that is to say either of safe operation, while being of reduced cost price.
On atteint ce but par le fait que deux lames de scie circulaire animées d'un mouvement de va-et-vient sont placées chacune sur un bras pivotant et sont entraînées en sens contraire chacune par un moteur, les bras pivotants changeant chacun de position, sur un chariot effectuant des mouvements de va-et-vient sous l'action d'un organe de traction, grâce à un organe de pivotement respectif, à chaque inversion du sens de déplacement du chariot et étant amenés dans une position oblique correspondant à l'épaisseur du matériau en plaque découpé de manière telle que c'est l'une des lames de scie circulaire qui opère dans l'un des sens de déplacement, et c'est l'autre lame qui opère dans l'autre sens de déplacement. This is achieved by the fact that two circular saw blades animated back and forth are each placed on a pivoting arm and are driven in opposite directions each by a motor, the pivoting arms each changing position, on a carriage performing back-and-forth movements under the action of a traction member, thanks to a respective pivoting member, each time the direction of movement of the carriage is reversed and being brought into an oblique position corresponding to the thickness of the plate material cut in such a way that it is one of the circular saw blades which operates in one direction of movement, and it is the other blade which operates in the other direction of movement .
La scie circulaire de long selon l'invention permet d'effectuer le découpage, non seulement pendant le mouvement d'aller, mais également pendant le mouvement de retour. Il en résulte un gain de temps considérable et, par suite, une augmentation de productivité, du fait que le découpage peut avoir lieu, même pendant le retour du chariot. The long circular saw according to the invention allows cutting to be carried out not only during the forward movement, but also during the return movement. This results in a considerable saving of time and, consequently, an increase in productivity, since the cutting can take place, even during the return of the carriage.
Un autre mode d'exécution avantageux de l'invention prévoit que les organes de pivotement sont des dispositifs cylindre-piston, hydrauliques ou pneumatiques qui sont articulés à l'une de leurs extrémités aux bras pivotants et, à leur autre extrémité, au chariot. Another advantageous embodiment of the invention provides that the pivoting members are cylinder-piston, hydraulic or pneumatic devices which are articulated at one of their ends to the pivoting arms and, at their other end, to the carriage.
On va décrire à présent avec davantage de détails un exemple de réalisation non limitatif de l'invention, en regard du dessin annexé dans lequel
- la figure 1 est une vue en coupe longitudinale schématique d'une scie circulaire de long
- la figure 2 est une vue de dessus d'un chariot;
- la figure 3 est une vue latérale d'un chariot.We will now describe in more detail a non-limiting exemplary embodiment of the invention, with reference to the appended drawing in which
- Figure 1 is a schematic longitudinal sectional view of a long circular saw
- Figure 2 is a top view of a carriage;
- Figure 3 is a side view of a carriage.
La figure 1 montre un bâti de machine 1 comportant un plateau porte-pièce 24 et deux rails de roulement parallèles 2 sur lesquels un chariot 3 comportant des galets de roulement 10 peut effectuer des mouvements de va-etvient. Le chariot 3 est mû par un moteur non représenté ici, placé sur un organe de traction 17 passant sur des poulies de guidage fixes 26. Sur le chariot 3, deux lames de scie circulaire 21 et 22 sont placées chacune sur un bras pivotant, 18 et 19,respectivement ; elles sont entraînées en sens contraire chacune par un moteur électrique, respectivement 4 et 5. Les moteurs 4 et 5 sont alimentés par un conducteur 20 qui aboutit à une prise de courant en passant par un galet.Selon la position de pivotement des bras pivotants 18 et 19, les lames de scie circulaire 21 et 22 se trouvent dans une fente longitudinale 25 du plateau 24 ou au-dessous de cèlui-ci. La figure 1 montre qu'une plaque 23 placée sur le plateau 24 est séparée par la lame de scie 21 se déplaçant de gauche à droite. Lorsque le chariot 3 se déplace de droite àgauche, c'est, par contre, la lame de scie 22 qui sépare la plaque 23. FIG. 1 shows a machine frame 1 comprising a work-holding plate 24 and two parallel rolling rails 2 on which a carriage 3 comprising rolling rollers 10 can perform reciprocating movements. The carriage 3 is driven by a motor not shown here, placed on a traction member 17 passing over fixed guide pulleys 26. On the carriage 3, two circular saw blades 21 and 22 are each placed on a pivoting arm, 18 and 19, respectively; they are each driven in opposite directions by an electric motor, respectively 4 and 5. The motors 4 and 5 are powered by a conductor 20 which leads to a socket via a roller. Depending on the pivoting position of the pivoting arms 18 and 19, the circular saw blades 21 and 22 are located in a longitudinal slot 25 of the plate 24 or below it. Figure 1 shows that a plate 23 placed on the plate 24 is separated by the saw blade 21 moving from left to right. When the carriage 3 moves from right to left, it is, however, the saw blade 22 which separates the plate 23.
Comme le montrent les figures 2 et 3, les deux moteurs 4 et 5 sont fixés sur le chariot 3 avec décalage dans le sens de la longueur des rails 2. Les moteurs 4 et 5 comportent des arbres 6 et 7 placés dans des paliers 8 et 9 et qui, par l'intermédiaire de courroies trapézoidales 11 et 12, entraînent les lames 21 et 22. Celles-ci sont fixées sur des arbres 27 et 28 placés aux extrémités libres des bras pivotants 18 et 19. Les bras pivotants 18 et 19 sont placés sur les arbres 6 et 7 de façon à pouvoir pivoter et ils sont articulés chacun, à distance de ceux-ci, à un dispositif cylindre-piston 13 et 14, respectivement, fixés au chariot 3 en un emplacement fixe On prévoit, sur chaque cylindre, un raccord 15 et 16 respectivement, de branchement d'une conduite à fluide sous pression non représentée ici.On peut, par suite, faire pivoter les lames de scie circulaire 21 et 22 de façon continue et indépendamment l'une de l'autre. As shown in Figures 2 and 3, the two motors 4 and 5 are fixed to the carriage 3 with offset in the length direction of the rails 2. The motors 4 and 5 have shafts 6 and 7 placed in bearings 8 and 9 and which, by means of trapezoidal belts 11 and 12, drive the blades 21 and 22. These are fixed on shafts 27 and 28 placed at the free ends of the pivoting arms 18 and 19. The pivoting arms 18 and 19 are placed on the shafts 6 and 7 so as to be able to pivot and they are each articulated, at a distance from these, to a cylinder-piston device 13 and 14, respectively, fixed to the carriage 3 at a fixed location. each cylinder, a connector 15 and 16 respectively, for connection of a pressurized fluid line not shown here. It is therefore possible to pivot the circular saw blades 21 and 22 continuously and independently of one of the 'other.
La scie circulaire de long selon l'invention fonctionne de la façon suivante. The long circular saw according to the invention operates as follows.
Sur le chariot 3 représenté en traits pleins sur la figure 1, la lame de scie circulaire de gauche 21 est dans une position de pivotement vers le haut telle qu'en se déplaçant de gauche à droite, -elle sépare la plaque 23. La lame de gauche 22 se trouve, par contre, complètement audessous du plateau 24 dans une position inactive. Dès que le chariot 3 a terminé son déplacement de gauche à droite, les lames 21 et 22 passent, en pivotant sous l'action des dispositifs à cylindre-piston 13 et 14 dans les positions représentées en tirets. A peu près en même temps, la plaque 23 est de nouveau positionnée pour une autre coupe, ou bien une nouvelle plaque est déposée. Le chariot 3 est alors de nouveau amené de droite à gauche dans la position initiale en étant tiré par le câble de traction 17, et il est clair que c'est la lame 22 qui découpe alors la plaque 23, tandis que la lame 21 se trouve en position inactive au-dessous du plateau 24. A l'aller, c'est donc la lame 21 qui est active et, au retour, la lame 22. A la fin de déplacement de gauche à droite, les lames 21 et 22 reviennent en pivotant dans leurs positions initiales. Les phases des mouvements du chariot 3 et des lames 21 et 22 peuvent être commandées à la main ou automatiquement par des éléments de manoeuvre non représentés ici et un dispositif de commande. On the carriage 3 shown in solid lines in FIG. 1, the left circular saw blade 21 is in an upward pivoting position such that, moving from left to right, it separates the plate 23. The blade on the left 22, on the other hand, is completely below the plate 24 in an inactive position. As soon as the carriage 3 has finished moving from left to right, the blades 21 and 22 pass, pivoting under the action of the piston-cylinder devices 13 and 14 in the positions shown in dashed lines. At about the same time, the plate 23 is again positioned for another cut, or else a new plate is deposited. The carriage 3 is then again brought from right to left in the initial position by being pulled by the traction cable 17, and it is clear that it is the blade 22 which then cuts the plate 23, while the blade 21 is found in the inactive position below the plate 24. On the outward journey, it is therefore the blade 21 which is active and, on the return, the blade 22. At the end of movement from left to right, the blades 21 and 22 return by pivoting to their original positions. The phases of the movements of the carriage 3 and of the blades 21 and 22 can be controlled by hand or automatically by operating elements not shown here and a control device.
