A conveyor system (1) with a support apparatus for maintaining non-pendular substantially straight-line motion of the material-conveying member (5) thereof, wherein the support apparatus includes straight-line linkage (18, 19) which is mounted between a rigid supporting surface (23) and the material- conveying member (5) so as to restrict movement of the material-conveying member (5) to a substantially straight-line non-pendular path parallel with the path of conveyance. Each straight-line linkage assembly (18, 19) which supports the material-conveying member includes a set of three linkage arms (39, 41, 43) which are pivotally interconnected with resilient bushings (45, 46, 52, 54, 56) that continually urge the linkage to a central neutral or resting position during movement thereof. Two of the linkage arms (39, 41) are pivotally connected in spaced relation at one end to a rigid support (21), and are each pivotally connected at their opposite end to a third intermediate linkage arm (43) which is disposed therebetween.

La présente invention concerne un système de convoyeur (1) doté d'un dispositif de support destiné à conserver au mouvement de l'organe (5) transporteur de matériaux du système de convoyeur une trajectoire non pendulaire essentiellement rectiligne. Le dispositif de support comporte en l'occurrence une liaison linéaire (18, 19) qui, établie entre une surface de support rigide (23) d'une part, et l'organe transporteur de matériaux (5) d'autre part, permet de conserver au mouvement de l'organe transporteur de matériaux (5) une trajectoire non pendulaire, essentiellement rectiligne, et parallèle au chemin de transport. Chaque ensemble de liaison rectiligne (18, 19) supportant l'organe transporteur de matériaux se compose d'un groupe de trois bras de liaison (39, 41, 43) articulés entre eux par des boîtes de glissement à action élastique (45, 46, 52, 54, 56) dont la tendance est de ramener en permanence la liaison vers une position centrale neutre ou de repos pendant son mouvement. Par l'une de leurs extrémités, deux des bras de liaison (39, 41) sont articulés pivotants sur un support rigide (21), conservant un entraxe substantiel entre eux. Par l'autre de leurs extrémités, ces bras sont articulés pivotants sur un troisième bras de liaison intermédiaire (43) qui les réunit.
