Roller-noise reduction in conveyor belts

摘要

Low-noise rollers in modular plastic conveyor belts. Energy-absorbing elements formed on belt rollers or in roller support structure is used to absorb the energy of impacts between rollers and the support structure. The energy-absorbing elements include resilient roller sections sandwiched between rigid sections, spring-like bent tabs on the end faces of rollers, hinged bumpers or flexible fingers between the end faces of the rollers and the roller support structure, and flexible structure protruding from the module into circumferential grooves in the outer cylindrical surface or circular grooves formed in the end faces of the rollers.

主权项

1. A conveyor belt comprising:
a plurality of rollers each having two opposite ends joined by an article-supporting outer surface; a plurality of axles rotatably supporting the rollers and defining axes of rotation about which the rollers are rotatable and along which the rollers are translatable, wherein the axles have two opposite ends; support structure for supporting the two opposite ends of the axles; an energy-absorbing element positioned on at least one of the support structure and the roller to absorb the energy of impacts between the rollers and the support structure as the conveyor belt moves.
