Title
(EN) METHOD AND APPARATUS FOR CONVEYING A SOLID MATERIAL
(FR) PROCEDE ET APPAREIL POUR LE TRANSPORT DE MATERIAU SOLIDE
Abstract
(EN)
A method and conveyor for conveying a solid material by means of parallel, oblong transfer elements (31, 32) that move back and forth in the direction of transfer. Most of the surface of the transfer elements moves in the direction of transfer at the same time and at least part of the surface thereof is inclined towards the centre of the conveyor. The pieces (9) lying on the inclined outermost transfer elements (32) are carried by means of the lower longitudinal edge of these transfer elements, the angle of inclination of said edge about the longitudinal axis being smaller than the angle of inclination of the upper edge thereof. Thus, the support force exerted by the transfer elements on the pieces or parts lying thereon, and the friction force between them and the pieces or parts lying thereon, increase. At the same time, the support force that second, with respect to the outermost transfer elements lower transfer elements (1, 20, 31) exert on the pieces or parts lying thereon, and the friction between them and the pieces or parts lying thereon, decrease.
(FR)
L'invention concerne un procédé et un transporteur pour le transport d'un matériau solide au moyen d'éléments de transferts oblongs et parallèles (31, 32) qui se déplacent en va-et-vient dans le sens du transfert. Pratiquement toute la surface des éléments de transfert se déplace en même temps dans le sens du transfert et au moins une partie de la surface est inclinée vers le centre du transporteur. Les pièces (9) reposant sur les éléments de transfert les plus à l'extérieur (32) sont portées par le bord longitudinal de ces éléments de transfert, l'angle d'inclinaison dudit bord autour de l'axe longitudinal étant inférieur à l'angle d'inclinaison du bord supérieur. Ainsi, la force de soutien exercée par les éléments de transfert sur les pièces ou les parties reposant sur ces derniers et la force de friction entre eux et les pièces ou les parties reposant sur ces derniers, augmentent. En même temps, la force de soutien que les deuxièmes éléments de transfert inférieurs (1, 20, 31) exercent sur les pièces ou les parties reposant sur ceux-ci, et la friction entre eux et les pièces ou parties reposant sur ceux-ci, décroît.
