Description
Dispositif de correction pour le bâti pendulaire d'une machine pour le sciage des pierres Correction device for the pendulum frame of a machine for sawing stones
La présente invention a pour objet un dispositif agencé de façon à assurer, de manière automatique et continue, le réglage de la position des centres d'oscillation des biellettes à mouvement pendulaire qui soutiennent le bâti porte-lames d'une machine pour le sciage des marbres, granits et autres pierres dures.The present invention relates to a device arranged so as to ensure, automatically and continuously, the adjustment of the position of the centers of oscillation of the pendulum movement rods which support the blade-holder frame of a machine for sawing marbles, granites and other hard stones.
On sait que dans les bâtis oscillants de ce type, il est nécessaire de compenser, au cours de l'opération de coupe, le déplacement du pied de la bielle d'actionnement par suite de la variation continue de la position du secteur d'oscillation des biellettes qui supportent le bâti porte-lames par rapport à l'axe vertical passant par le centre de pivotement desdites biellettes.It is known that in oscillating frames of this type, it is necessary to compensate, during the cutting operation, for the displacement of the foot of the actuating rod as a result of the continuous variation of the position of the oscillation sector. rods which support the blade-holder frame with respect to the vertical axis passing through the pivot center of said rods.
Dans tous les systèmes connus à l'heure actuelle, ceci est obtenu en manoeuvrant manuellement un boulon qui permet de régler la longueur de la bielle d'actionnement qui assure le déplacement alternatif du bâti porte-lames. Or, pour des raisons évidentes de sécurité, cette manoeuvre est effectuée après que la machine ait été arrêtée, ce qui introduit un effet de discontinuité dans le travail et implique des pertes de temps non négligeables en pratique.In all systems known at present, this is obtained by manually operating a bolt which makes it possible to adjust the length of the actuating rod which ensures the reciprocating movement of the blade holder frame. However, for obvious safety reasons, this maneuver is carried out after the machine has been stopped, which introduces a discontinuity effect in the work and involves considerable loss of time in practice.
L'adoption du dispositif à excentriques tournants tel que défini dans la revendication 1 ci-après permet une compensation automatique et continue de la position du pied de bielle au cours de l'opération de coupe, sans qu'il soit nécessaire d'arrêter la machine.The adoption of the rotary eccentric device as defined in claim 1 below allows automatic and continuous compensation of the position of the big end during the cutting operation, without the need to stop the machine.
Le dessin annexé, donné à titre d'exemple, permettra de mieux comprendre l'invention, les caractéristiques qu'elle présente et les avantages qu'elle est susceptible de procurer :
Fig. 1 est une vue de côté montrant de manière très schématique l'agencement général d'une machine de sciage équipée d'un dispositif à excentriques tournants suivant l'invention.The appended drawing, given by way of example, will allow a better understanding of the invention, the characteristics which it presents and the advantages which it is capable of providing: Fig. 1 is a side view very schematically showing the general arrangement of a sawing machine equipped with a rotary eccentric device according to the invention.
Fig. 2 représente de la même manière, mais à plus grande échelle, le détail du mécanisme de commande du dispositif envisagé.Fig. 2 shows in the same way, but on a larger scale, the detail of the control mechanism of the envisaged device.
Fig. 3 est une vue de détail en élévation par l'avant.Fig. 3 is a detail view in elevation from the front.
Fig. 4 est un schéma géométrique illustrant le fonctionnement du dispositif.Fig. 4 is a geometric diagram illustrating the operation of the device.
Conformément à l'invention et comme illustré en fig. 1, les axes ou pivots 1 et 2 sur lesquels s'articulent les biellettes 3 et 4 du bâti pendulaire porte-lames 5 d'une machine pour le sciage des marbres, granits et autres pierres dures, sont soutenus par des disques ou excentriques 6 et 7 qui sont régulièrement entraînés en rotation au cours du mouvement de descente dudit bâti 5 faisant suite à l'avance du travail de coupe, afin de compenser de manière continue la variation qui affecte la position du pied de bielle 8 au fur et à mesure que la bielle d'actionnement 9 mise en mouvement par la rotation du volant 10 se déplace verticalement vers le bas.In accordance with the invention and as illustrated in FIG. 1, the axes or pivots 1 and 2 on which the rods 3 and 4 of the pendular blade-holder frame 5 of a machine for sawing marble, granite and other hard stones are articulated, are supported by discs or eccentrics 6 and 7 which are regularly driven in rotation during the downward movement of said frame 5 following the advance of the cutting work, in order to continuously compensate for the variation which affects the position of the small end 8 as and when that the actuating rod 9 set in motion by the rotation of the flywheel 10 moves vertically downwards.
Sur la vue de détail de fig. 2, on peut observer le mécanisme destiné à l'entraînement continu en rotation du disque ou excentrique 7 supportant le pivot 2 de l'une des biellettes 4. Ce disque est monté sur un petit bâti qui se déplace le long de l'une des colonnes 11 de la machine, laquelle colonne comporte une denture de crémaillère 13 qui engrène avec un pignon 12 lié angulairement audit disque à travers un réducteur 14, du type à vis sans fin et à roue hélicoïdale.In the detail view of fig. 2, we can observe the mechanism for the continuous drive in rotation of the disc or eccentric 7 supporting the pivot 2 of one of the rods 4. This disc is mounted on a small frame which moves along one of the columns 11 of the machine, which column has a rack tooth 13 which meshes with a pinion 12 angularly connected to said disc through a reducer 14, of the worm and helical wheel type.
En fig. 3 on note que chaque biellette 4 se présente sous la forme d'un portique afin de soutenir les deux côtés opposés du bâti porte-lames 5.
Fig. 4 fait ressortir que les disques o u excentriques 6 et 7 qui soutiennent les biellettes 3 et 4 tournent de façon à amenel l e s pivots 1 et 2 sur le coté opposé desdits excentriq uesIn fig. 3 it is noted that each link 4 is in the form of a gantry in order to support the two opposite sides of the blade holder frame 5. Fig. 4 shows that the discs or eccentrics 6 and 7 which support the rods 3 and 4 rotate so as to bring the pivots 1 and 2 on the opposite side of said eccentric
(position 1' et 2') lorsqu' au cours de sa descente le bâti porte-lames, vient s'aligner avec l'axe de la bielle 10, pour ramener lesdits pivots à l'orientation originale (position 1" et 2") lorsque le bâti au cours du sciage descend au-dessous de la ligne de symmétrie.(position 1 'and 2') when, during its descent, the blade holder frame, comes to align with the axis of the connecting rod 10, to bring said pivots back to the original orientation (position 1 "and 2" ) when the frame during sawing drops below the line of symmetry.
II convient de relever que les mouvements oscillants des biellettes 3 et 4 restent maintenus à des positions toujours symétriques par rapport aux axes verticaux qui passent par les pivots 1 et 2, en assurant de la sorte un fonctionnement optimal des lames de coupe à toutes les phases du travail. La compensation de cette position s'effectue de manière automatique et continue, sans nécessiter aucune intervention des opérateurs, en permettant une réduction sensible des temps de travail.It should be noted that the oscillating movements of the links 3 and 4 remain maintained at positions always symmetrical with respect to the vertical axes which pass through the pivots 1 and 2, thereby ensuring optimal operation of the cutting blades at all phases work. The compensation of this position is carried out automatically and continuously, without requiring any intervention from the operators, allowing a significant reduction in working times.
On observera encore que l'emploi de biellettes plus courtes autorisé par le dispositif suivant l'invention permet de diminuer dans une mesure non négligeable les dimensions et l'encombrement du bâti pendulaire.
It will also be observed that the use of shorter connecting rods authorized by the device according to the invention makes it possible to considerably reduce the dimensions and the size of the pendulum frame.
