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.

An accumulation-and-release conveyor using a roller belt with rollers arranged to rotate in the direction of belt travel. The rollers extend through the thickness of the belt. A movable stop is positioned along the carryway just downstream of a bearing surface that is movable into and out of contact with the rollers. When the bearing surface is out of contact with the rollers, they are freely rotatable; when the bearing surface contacts the rollers, they roll on the bearing surface to propel articles in the direction of belt travel. The stop is selectively moved between a blocking position preventing articles from passing and accumulating them with low back line pressure on the freely rotatable rollers and a release position allowing articles to pass to the accumulation zone where they are propelled forward and separated from each other by the rotation of the rollers rolling on the bearing surface.

A package-culling conveyor system and a method for culling flat packages from a bulk flow of flat and non-flat packages. The conveyor system includes a tilted conveyor belt that conveys flat packages along its length while non-flat packages tumble off its lower side edge to initially cull flat packages from a bulk flow of packages. Retention means, such as a high-friction outer conveying surface or a raised barrier along the length of the outer conveying surface of the tilted conveyor belt, holds flat packages on the tilted conveyor belt. The initially separated packages are more fully culled in a conveyor comprising a roller conveyor belt with package-supporting belt rollers rotated in a direction to push packages sidewise toward a culling element that extends along the length of the roller conveyor belt. Examples of culling elements include powered rollers and vertical walls forming side guards. The powered roller lifts the contact side of non-flat packages to free flat packages underneath.

A tiltable lift and a method for using it to aid the unloading of a pallet. The tiltable lift comprises a lift mounted atop a tiltable platform. A pallet load of pallet load elements, such as containers, cartons, boxes, trays, or bundles, deposited on the lift is tilted. A wall extending upward from the platform receives a side of the tilted pallet load, which is urged against the wall by gravity. The lift lifts the pallet load along the wall to position the topmost layer of the pallet load at a top end of the wall for easy access and removal of pallet load elements from the pallet.

A case turner comprising a powered roller conveyor with a bump turn and a tapered roller just downstream of the bump turn to assist in turning cases completely 90. The larger diameter of the tapered roller is on the opposite side of the conveyor from the bump turn.

A conveyor system and methods for conveying and unstacking flat and non-flat packages. The conveyor system includes an inclined conveyor belt delivering packages to a tilted conveyor belt that conveys flat packages along its length while non-flat packages tumble off its lower side edge to initially cull flat packages from a bulk flow of packages. Retention means, such as a high-friction outer conveying surface or a raised barrier along the length of the outer conveying surface of the tilted conveyor belt, holds flat packages on the tilted conveyor belt. The inclined conveyor belt has stop elements spaced apart along the belt's length and is advanced in stop-and-go fashion to help unstack piggy-backed packages as they are conveyed up the incline. The initially separated packages are more fully culled in a conveyor comprising a roller conveyor belt with package-supporting belt rollers rotated in a direction to push packages sidewise toward a culling element that extends along the length of the roller conveyor belt.

An article induction system for preparing a stream of articles, such as mail parcels, for processing employs a series of conveyors operating under control of a controller for feeding articles to an operator at a cull belt at an optimal paced rate. The article induction system includes a destacking section, a separation and alignment section, a buffer section and a culling section manned by an operator. A controller controls the speed of each component based on measurements provided by sensors so as to feed articles to the operator at a desired paced rate.
