Title
(EN) DIRECT DRIVE CONVEYOR BELT SYSTEM
(FR) SYSTÈME DE COURROIE TRANSPORTEUSE À ENTRAÎNEMENT DIRECT
Abstract
(EN)
A direct drive conveyor belt comprises an endless toothed thermoplastic belt and multiple driving pulleys working in tandem. The pulleys have driving sheaves and non-driving sheaves and the belt teeth are adapted to engage the driving sheaves as the belt wraps around the pulleys. The pulleys are driven by a common drive shaft through continuous duty clutches and are out of phase with each other such that the belt teeth are alternately engaged by driving sheaves on different pulleys. The pulleys can also be independently driven. The endless belt can alternately be driven by a computer controlled motor with an external rotor with sheaves where the speed of the motor is accelerated between successive engagements of a belt tooth.
(FR)
L'invention concerne une courroie transporteuse à entraînement direct qui comprend une courroie thermoplastique crantée sans fin et plusieurs poulies d'entraînement fonctionnant en tandem. Les poulies possèdent des poulies motrices et des poulies non motrices et les crans de la courroie sont adaptés pour venir en prise avec les poulies motrices lorsque la courroie s'enroule autour des poulies. Les poulies sont entraînées par un arbre d'entraînement commun au moyen d'embrayages à fonctionnement continu et sont déphasées les unes par rapport aux autres de sorte que les crans viennent alternativement en prise avec des poulies d'entraînement sur différentes poulies. Les poulies peuvent aussi être indépendamment entraînées. La courroie sans fin peut être alternativement entraînée par un moteur commandé par ordinateur équipé d'un rotor extérieur pourvu de poulies, ce qui a pour effet d'accélérer la vitesse du moteur entre des prises successives d'un cran de courroie.
