Title (EN) SIDE PLATE FOR A PLASTIC SPIRAL CONVEYOR BELT SYSTEM
(FR) PLAQUE LATERALE POUR UN SYSTEME A BANDE TRANSPORTEUSE SPIRALEE EN PLASTIQUE
Abstract:
(EN) A side plate (10) for a modular plastic conveyor belt for use in a spiral conveyor belt system has one or more generally vertical grooves (26) formed in its outer side, for engagement with protruding structure of cage bars of a spiral conveyor driving cage (40). At least one of the grooves (26) is positioned on a common center with a countersink bore which receives a plastic rod head of a connecting rod in the modular conveyor belt. In cooperation with the side plate grooves are bumps or protrusions (42) on the cage bars of the driving cage. These may be formed in cage bar caps (44) which are assembled onto the exterior of the cage bars. At least some of the bumps (42) on the cage bars are at any one time engaged in side plate grooves (26), providing assistance in the driving of the spiral conveyor belt by the driving cage (40).
(FR) Une plaque latérale (10) pour une bande transporteuse modulaire en plastique utilisée dans un système à bande transporteuse en spirale possède une ou plusieurs rainures (26) généralement verticales formées dans son côté externe dans lesquelles se logent des barres d'une cage d'une structure saillante d'une cage (40) d'entraînement de la bande transporteuse en spirale. Au moins l'une des rainures (26) est positionnée sur un centre commun avec un alésage fraisé qui reçoit une tête de bielle en plastique d'une bielle de connexion dans la bande transporteuse modulaire. Des bosses ou des protubérances (42) sur les barres de la cage d'entraînement coopèrent avec les rainures de la plaque latérale. Ces protubérances peuvent être formées dans des chapeaux (44) des barres de la cage et qui sont assemblées sur l'extérieur des barres de la cage. Au moins certaines des protubérances (42) sur les barres de la cage sont logées à n'importe quel moment dans les rainures (26 )de la plaque latérale, constituant ainsi une assistance à l'entraînement de la bande transporteuse en spirale par la cage d'entraînement (40).
