  • Patent number: 9022206
    Abstract: A cleaning device is provided for removing debris from rotating conveyor rollers, and includes a housing constructed and arranged for insertion between two adjacent rotating rollers, the housing having a first set of cleaning wheels at a first housing end associated with a first of the conveyor rollers, and a second set of cleaning wheels located on an opposite end of the housing and associated with a second of the conveyor rollers. At least one of the cleaning wheels is reciprocable relative to the housing between a retracted position permitting insertion of the housing between the rollers, and a extended position extending the reciprocating wheel towards the adjacent roller for limiting lateral movement of the housing between the rollers. Upon movement of the housing between the rollers in a direction parallel to a longitudinal axis of the rollers, the cleaning wheels operationally engage and remove residue collected on the rollers.
