Abstract
A sound attenuated material handling element reduces vibration and sound in a material handling system. The material handling element may be a sound attenuated roller for use in a roller conveyer or a sound attenuated nestable tote for receiving and transporting articles in the material handling system. Reducing vibration in material handling element reduces the noise produced by the element. The sound attenuated roller includes sound attenuating material disposed inside of the roller and in contact with the inner surface of the roller body. The sound attenuated nestable tote includes sound dampening material disposed in or formed with the tote structure. The sound damping material may be integrally formed with the roller or tote in order to maximize vibration and noise attenuation. Three dimensional computer analysis may be used to determine optimized locations for placement of the sound damping material on the roller or tote.
