Title
(EN) SAWING MACHINE FOR CUTTING BLOCKS OF STONE MATERIAL WITH A CONVEYOR BELT PROVIDED WITH A CLAMP FOR CLAMPING THE BLOCK OF STONE
(FR) MACHINE À SCIER POUR COUPER DES BLOCS DE MATÉRIAU DE PIERRE AVEC UNE BANDE TRANSPORTEUSE MUNIE D'UNE PINCE POUR SERRER LE BLOC DE PIERRE
Abstract
(EN)
The present invention relates to a sawing machine (1) which comprises at least one stationary element (8) arranged vertically on the conveyor belt (2) to allow the block of material (3) to be cut to rest against it, and at least one mechanical locking element (9) consisting of a main body (15) adapted to be removably, transversely disposed to the conveying direction of the conveyor belt (2) at said stationary element (8), and adapted to move from a first rest position in which the locking element (9) is not in contact with the block of material (3) to be cut at a second operating position in which said locking element (9) presses said block of material (3) to be cut against said stationary element (8). In this way, the blocks of material (3) to be cut are clamped between the stationary element (8) and the locking element (9) until the cutting station is reached; the locking element (9) can be positioned on the conveyor belt (2) and removed from it each time the cutting operation of a block of material (3) is completed and that a new block of material (3) to be cut is to be locked.
(FR)
La présente invention concerne une machine à scier (1) qui comprend au moins un élément fixe (8) disposé verticalement sur la bande transporteuse (2) pour permettre au bloc de matériau (3) à couper de s'appuyer contre celui-ci et au moins un élément de verrouillage mécanique (9) constitué d'un corps principal (15) conçu pour être disposé de manière amovible, transversalement à la direction de transport de la bande transporteuse (2) au niveau dudit élément fixe (8) et conçu pour se déplacer d'une première position de repos, dans laquelle l'élément de verrouillage (9) n'est pas en contact avec le bloc de matériau (3) à couper, vers une seconde position de fonctionnement, dans laquelle ledit élément de verrouillage (9) presse ledit bloc de matériau (3) à couper contre ledit élément fixe (8). De cette manière, les blocs de matériau (3) à couper sont serrés entre l'élément fixe (8) et l'élément de verrouillage (9) jusqu'à ce que la station de coupe soit atteinte ; l'élément de verrouillage (9) peut être positionné sur la bande transporteuse (2) et retiré de celle-ci à chaque fois que l'opération de coupe d'un bloc de matériau (3) est achevée et qu'un nouveau bloc de matériau (3) à couper doit être verrouillé.
