  • Patent number: 9327905
    Abstract: A conveyor belt module includes a body, a link end formed by the body, and an opening through the link end along a hinge axis. A cover extends from the body in a direction of the hinge axis and a post extends from the cover; a bearing is rotatably engaged with the post. A fastener engages the post to capture the bearing between the cover and the fastener, such that the bearing is housed at least partially between the upper and lower extremes of the body. A track for supporting and guiding the conveyor belt module includes a guide arm extending into a guide channel defined by the body to engage the bearing. The conveyor belt module may also include laterally offset protrusions extending from the link end in opposite directions to inhibit engagement with a drive member.

  • Patent number: 9227785
    Abstract: A modular conveying assembly includes active roller control for reducing backline pressure without product to product contact when accumulating products. The conveying assembly includes a first roller belt module having a top surface and at least one first roller axle support extending above the top surface. The first axle support supports at least one roller above the top surface. The at least one roller is rotatably coupled to a rotatably driven drive axle, such that rotation of the drive axle causes rotation of the roller. A clutch including a driven surface fixed to the drive axle engages a driving member to rotatably drive the drive axle and, thus the roller.
