Abstract
A belt guide for a drive belt of a roller conveyor that cants the belt in the skewed roller section of the conveyor so that an edge portion of the belt, and not the entire width, engages the skewed rollers to impart driving motion. This is accomplished by providing a series of free-wheeling cam followers that support the raised edge portion of the drive belt that contacts the skewed rollers. A second series of freely rotatable grooved wheels or sheaves is provided whose grooved portion captures the lower edge portion of the drive belt.
Claims6
In a belt-driven roller conveyor having parallel frame members, a plurality of conveyor rollers having axes of rotation and being mounted obliquely with respect to the frame members, and a belt having a surface with a width defined by first and second edges, the belt frictionally engaging the conveyor rollers to impart rotation to the conveyor rollers about their axes, a belt guide comprising:
- a first series of at least one guide roller adapted to engage the first edge of the belt;
- a second series of at least one guide roller adapted to engage the second edge of the belt;
- whereby the first and second series of guide rollers support the belt so that only the surface of the belt adjacent one of the first or second edges thereof engages the obliquely mounted conveyor rollers to impart rotational movement thereto.
