Self-aligning conveyor belt cover system

摘要

A conveyor has a belt arranged to be urged around conveyor rollers, and a belt cover formed of an endless loop of fabric material which is in frictional communication over the belt. The belt cover is formed of a polyester carcass that has a monofilament weft that is transverse to the direction of travel, and maintains alignment with the belt. The belt cover is installed to a tensile force of between 1 and 1.5 pounds/inch, corresponding to an overall elongation of approximately 0.1%, which allows frictional communication between cover and belt for load transmission without binding. The communication between the belt cover and the belt has a coefficient of friction of ˜0.50. A message is printed on the belt cover. In addition, an antimicrobial material is disposed on the belt cover, and is formed of silver nanoparticles embedded in a polyurethane film having a thickness of ˜0.5 mil.

主权项

1. A conveyor arrangement of the type having a conveyor belt and a plurality of conveyor rollers, the conveyor arrangement comprising:
a base conveyor belt arranged to be urged endlessly around the plurality of conveyor rollers in a path; and a conveyor belt cover formed of an endless loop of fabric and arranged to overlie said base conveyor belt and to be urged endlessly around the plurality of conveyor rollers along substantially the same path, said conveyor belt cover being in frictional communication with, and multidirectionally displaceable over, said base conveyor belt.
