Title
(EN) CONVEYOR BELT TRAINER
(FR) ENTRAINEMENT A BANDE TRANSPORTEUSE
Abstract
(EN)
An apparatus for training a conveyor belt (30) is formed by a training roller (40) enclosing a concentric shaft (60) around which it is rotatably mounted. The roller (40) is also pivotable relative to the shaft (60) about a pivot axis that is transverse to the longitudinal axis of the shaft (60). This means that when the belt (30) is properly aligned, the force of the belt (30) against the roller (40) is equally distributed on both sides of the pivot axis of the roller (40). However, when the belt (30) becomes misaligned, the roller (40) pivots in response to the unequal force of the belt (30) on opposite sides of the pivot axis to realign the belt (30). The roller (40) is coupled to the shaft (60) by a pair of friction rings (80) so that reversing the belt (30) rotates the shaft (60) between first and second positions, thereby rotating the pivot axis of the roller (40) so that the roller (40) continues to train the belt (30).
(FR)
Dispositif d'entraînement à bande (30) transporteuse constitué d'un rouleau (40) d'entraînement entourant un arbre (60) concentrique autour duquel il est monté de manière rotative. Le rouleau (40) tourne également par rapport à l'arbre (60) autour d'un axe d'articulation transversal par rapport à l'axe longitudinal de l'arbre (60). En d'autres termes, lorsque la bande (30) est correctement alignée, sa force contre le rouleau (40) est répartie de manière équilibrée sur les deux côtés de l'axe d'articulation du rouleau (40). Toutefois, dans le cas où la bande (30) se décentre, le rouleau (40) pivote en réaction au déséquilibre de la force de la bande (30) sur les côtés opposés de l'axe d'articulation afin de réaligner la bande (30). Le rouleau est couplé avec l'arbre (60) par deux bagues de frottement (80) de sorte que le mouvement inversé de la bande (30) fait tourner l'arbre (60) entre les première et seconde positions, ce qui fait tourner l'axe d'articulation du rouleau (40), ce dernier (40) continuant d'entraîner la bande (30).
