    Abstract: A conveyor and a method for metering articles on a conveyor belt advancing in a direction of belt travel. Article-supporting rollers in the belt are actuated by a stationary bearing surface defining an upstream acceleration zone to accelerate articles forward along the conveyor belt. An activation belt advancing in the direction of belt travel at a speed faster than the conveyor belt provides a mobile bearing surface that actuates the belt rollers to rotate opposite to the direction of belt travel in a downstream deceleration zone. The conveyor belt also has regularly spaced retractable flights, which are retracted by contact with the stationary bearing surface in the acceleration zone and extended into a blocking position by contact with the mobile bearing surface in the deceleration zone. Articles in the deceleration zone are pushed rearward atop the rollers into metered positions against the leading faces of the flights.

  • Patent number: 8167118
    Abstract: A conveyor, a conveyor belt used in the conveyor, and a belt module used to construct the conveyor belt, in which the module includes belt rollers that extend outward of a conveyor surface of the modules to support conveyed articles. The belt rollers are mounted in cavities in the modules that open onto the conveying surface and a recessed surface recessed inward of an outermost surface opposite the conveying surface through the thickness of the modules. Bearing surfaces, such as the peripheries of conveyor rollers underlying the conveyor belt along a carryway run, extend into the conveyor belt past the outer surface to contact the belt rollers. As the belt advances, the belt rollers rotate on the bearing surfaces to push conveyed articles along or across the belt.

  • Patent number: 8167119
    Abstract: A low-pressure accumulation system and a conveyor belt in an accumulation conveyor for the use with the system. The belt, which is flanked on opposite sides by lines of gravity rollers, has a longitudinal lane of article-supporting belt rollers arranged in groups along the length of the conveyor belt. The groups are spaced apart from each at regular intervals. Trays sit atop the gravity rollers until they are lifted slightly higher by one of the slightly elevated groups of article-supporting belt rollers, which engage the bottom of the tray and convey it along toward a discharge end. Retractable stops selectively block the trays from advancing on the accumulation conveyor. The freely rotatable article-supporting belt rollers roll along the bottoms of any blocked and accumulated trays and provide low back pressure. The belt may also include low-friction rollers that ride on bearing surfaces below the belt to help lower friction between the belt and the conveyor structure while the belt is running.
