<p>The conveyor system, for conveying goods from one point to another, has its rollers (11,13,15,16) partly on a fixed frame (7) and partly on a moving frame (8) moving relative to the fixed frame. When the moving frame moves in one direction, the conveyor belt (4) remains stationary relative to the moving frame, while in the other direction the belt moves relative to the moving frame. The number of steps in which the belt moves is variable. S-shaped deflection rollers (15,16) guide the belt between its input end (12) and output end (14). One of these rollers is on the moving frame and the other on the fixed frame.</p> |
