Abstract
A conveyor belt including a plurality of rollers that serve as tensile members for the conveyor belt. In some embodiments, the rollers include roller members that rotate about longitudinal shafts, wherein the roller shafts receive and transmit tensile forces along a longitudinal direction of the conveyor belt. In some embodiments, nothing exists between adjacent roller members across a width of the conveyor belt.
Claims24
A conveyor belt comprising:
- a plurality of rollers extending across a width of the conveyor belt, wherein the rollers serve as tensile members for the conveyor belt and wherein no belt component is positioned between adjacent rollers across the width of the conveyor belt.
A conveyor belt comprising:
- a plurality of transverse rows of rollers, each roller including a roller member and a longitudinal shaft about which the roller member can rotate, the longitudinal shafts being aligned with a longitudinal direction of the conveyor belt, the longitudinal shafts defining an opening at each end;
- and
- transverse shafts extending through the openings of the longitudinal shafts of the rollers of adjacent transverse rows so as to pivotally connect adjacent transverse rows together;
- wherein the longitudinal shafts alone receive and transmit tensile forces imposed upon the conveyor belt in the transverse rows between adjacent transverse shafts along the longitudinal direction of the conveyor belt.
1 more element
A conveyor belt comprising:
- a plurality of transverse rows of rollers, each roller including a roller member and a longitudinal shaft about which the roller member can rotate, the longitudinal shafts being aligned with a longitudinal direction of the conveyor belt;
- spacer members that maintain predetermined spacing between the rollers of each transverse row, the spacer members receiving ends of the longitudinal shafts and having transverse openings;
- and
- transverse shafts extending through the transverse openings of the spacer members so as to pivotally connect adjacent transverse rows together;
- wherein the longitudinal shafts, spacer members, and transverse shaft receive and transmit substantially all tensile forces imposed upon the conveyor belt in the longitudinal direction of the conveyor belt.
2 more elements
A roller for a conveyor belt, the roller comprising:
- a roller member;
- and
- a shaft to which the roller member is mounted and can rotate about, the shaft comprising an eyelet at each end that defines an opening adapted to receive a transverse shaft of the conveyor belt, the eyelets being offset relative to each other in a transverse direction so as to enable alignment of the shaft with a shaft of an adjacent roller along a longitudinal direction of the conveyor belt, wherein the shaft is adapted to receive and transmit tensile forces along the longitudinal direction of the conveyor belt.
