Title
(EN) TRAY CONVEYOR
(FR) CONVOYEUR A PLATEAUX
Abstract
(EN)
A tray conveyor, comprising a plurality of independent trays (1) guided on at least one guide track (30, 31) and carried upon an air cushion, wherein the air supply is provided by said track itself, only when said tray is present upon the track and at the level thereof. The guide track includes an upper, substantially horizontal sole (31), with valve ends (3) terminating at the sole through apertures (4a, 5a) provided at regular intervals, according to the length of the trays (1) and the loads that may be carried thereupon. In dynamic operation, said valves (3) are open and discharge a compressed air jet when their apertures (4a, 5a) are covered by a tray (1), and are otherwise completely closed.
(FR)
Convoyeur à plateaux comprenant une pluralité de plateaux indépendants (1) guidés selon au moins une voie de guidage (30, 31), et reposant sur un coussin d'air, l'alimentation en air étant réalisée par la voie elle-même, uniquement en présence du plateau sur ladite voie et au seul niveau de celui-ci. La voie de guidage comportant une sole supérieure (31) sensiblement horizontale, au nivau de laquelle débouchent par des orifices (4a, 5a) à intervalle régulier, fonction de la longueur des plateaux (1) et des charges qu'ils sont susceptibles de porter, les extrémités de clapets (3). En fonctionnement dynamique, lesdits clapets (3) sont ouverts et libèrent un jet d'air comprimé lorsque leurs orifices (4a, 5a) sont recouverts par un plateau (1), et complètement obturés dans le cas contraire.
