Japanese Patent JP2002534337
Kind Code:
A
Abstract:
A roller conveyor belt driver system for a roller conveyor includes a closed loop belt having a continuous driving surface and a non-circular base and a plurality of pulleys which support and engage said non-circular base for at least partially laterally restraining the belt from rotation. A first group of pulleys are constructed and arranged to position the belt in non-orthogonal orientation with respect to the rollers of the conveyor for contacting one or more rollers with the driving surface of the belt. Optionally, the belt driver system includes a lateral restraint associated with a respective pulley of the first group of pulleys to urge the belt to remain engaged with the respective pulley to prevent twisting of the belt and, therefore, increase the life of the belt. For example, the lateral restraint may comprise a bearing which is positioned adjacent the respective pulley and which contacts the belt to maintain the belt in proper orientation in the pulley. In one form, the belt comprises a link belt, which is formed from a plurality of interlocking links, which permits the belt to be easily removed for service or replacement.
