Modular roller-top conveyor belt
First Claim
1. A modular conveyor belt comprising a series of rows of belt modules and hinge pins hingedly interlinking consecutive belt rows end-to-end to form an endless conveyor belt, each row including at least one module comprising a body section extending from a first end to a second end in the direction of belt travel, a first plurality of hinge elements along the first end, and a second plurality of hinge elements along the second end, the first plurality of hinge elements of a row being interleaved with the second plurality of hinge elements of an adjacent row and pivotally joined by a hinge pin in a hinged connection between consecutive rows of belt modules, wherein the body section of at least some of the modules includes a bottom surface and an opposite upper surface and at least one cavity formed in the body section and opening onto the upper surface and a roller rotatably disposed in the cavity for rolling contact with articles conveyed on the belt.

Abstract
A modular roller-top conveyor belt constructed of a series of rows of belt modules having hinge elements at opposite ends of each row. The hinge elements of each row are interleaved with the hinge elements of an adjacent row and interlinked by hinge pins to form an endless conveyor belt. Each of the belt modules includes a body section extending between opposite ends of each row in the direction of belt travel. Cavities formed in at least some of the modules open onto an upper conveying surface of the belt. Rollers residing in the cavities protrude onto the upper conveying surface to engage conveyed articles in rolling, low-friction contact. The rollers may be cylindrical rollers that rotate about axles, spherical balls that rotate in all directions, or caster-like roller assemblies.

11. A modular conveyor belt suitable for transferring articles off a side edge of the belt, comprising a series of rows of belt modules and hinge pins hingedly interlinking consecutive belt rows end-to-end to form an endless conveyor belt, each row extending between two side edges and including at least one module comprising a body section extending from a first end to a second end in the direction of belt travel and forming an upper article conveying surface, a first plurality of hinge elements along the first end, and a second plurality of hinge elements along the second end, the first plurality of hinge elements of a row being interleaved with the second plurality of hinge elements of an adjacent row and pivotally joined by a hinge pin in a hinged connection between consecutive rows of belt modules, wherein the body section of at least some of the modules includes:
-
a pair of opposing walls formed in the body section transverse to the direction of belt travel and bounding a cavity opening onto the upper article conveying surface, an axle extending across the cavity through the pair of opposing walls, and a roller disposed in the cavity with a salient portion protruding above the upper article conveying surface and encircling the axle for rotation about an axis of rotation as defined by the axle. - View Dependent Claims (12)
