Abstract
A modular conveyor belt constructed of modules having upstanding ribs, each in the form of textured upper ridge structure atop an elongated rib base. Consecutive ribs are spaced apart laterally on the top surface of the modules. Longitudinal slots between laterally consecutively ribs admit the fingers of transfer plates for smooth transfer of articles on and off the belt. The textured rib structure includes rows of teeth, truncated pyramids or cones, corrugated structure, and sinuous beads atop which articles are supported with little slipping in wet conditions.
Claims33
A conveyor belt module comprising:
- a module body extending longitudinally from a first end to a second end, laterally from a first side edge to a second side edge, and in thickness from a top side to a bottom side, the module body comprising:
- a first set of hinge eyes spaced apart laterally along the first end;
- a second set of hinge eyes spaced apart laterally along the second end;
- a flat surface on the top side;
- a plurality of laterally spaced longitudinal ribs including a solid elongated base extending outward of the flat surface and textured upper ridge structure atop the base to support conveyed articles;
- wherein the textured upper ridge structure of each rib comprises two longitudinal rows of teeth separated laterally by a longitudinal groove.
A conveyor belt module comprising:
- a module body extending longitudinally from a first end to a second end, laterally from a first side edge to a second side edge, and in thickness from a top side to a bottom side, the module body comprising:
- a first set of hinge eyes spaced apart laterally along the first end;
- a second set of hinge eyes spaced apart laterally along the second end;
- a flat surface on the top side;
- a plurality of longitudinal rows of truncated rectangular pyramids extending outwardly of the flat surface and defining notches between consecutive pyramids in each row,
- wherein each row is spaced laterally from another row to form a longitudinal slot between consecutive rows,
- wherein the longitudinal dimension of the notches is less than the lateral dimension of the slots between consecutive rows.
A conveyor belt module comprising:
- a module body extending longitudinally from a first end to a second end, laterally from a first side edge to a second side edge, and in thickness from a top side to a bottom side, the module body comprising:
- a first set of hinge eyes spaced apart laterally along the first end;
- a second set of hinge eyes spaced apart laterally along the second end;
- a flat surface on the top side;
- a plurality of laterally spaced longitudinal ribs extending outwardly of the flat surface and having laterally spaced first and second side walls,
- wherein each rib is characterized by longitudinally spaced notches extending through the rib from the first side wall to the second side wall.
A conveyor belt module comprising:
- a module body extending longitudinally from a first end to a second end, laterally from a first side edge to a second side edge, and in thickness from a top side to a bottom side, the module body comprising:
- a first set of hinge eyes spaced apart laterally at the first end;
- a second set of hinge eyes spaced apart laterally at the second end;
- a plurality of teeth arranged at the top side into a plurality of longitudinal rows of teeth separated by longitudinal slots extending longitudinally along the top side,
- wherein each tooth defines with a consecutive tooth on a row a notch that separates the consecutive teeth longitudinally, and
- wherein the longitudinal dimension of the notches is less than the lateral dimension of the slots.
