Abstract: A decentralized tracking system is discussed herein. The decentralized tracking system can be comprised of two or more tracking elements and be used to track packages moving on a conveyor system. Each tracking element can operate independently, despite being highly sophisticated and dynamically coordinated with one or more other tracking elements. The conveyor system can be a modular and/or accumulation conveyor system that has sorting functionality. The decentralized tracking system can be used to divert packages for sortation by, for example, embedding a destination zone into the package's tracking data and/or preprogramming conveyor zones to sort specific packages based on a package identifier.

Abstract: A drive controller for controlling movement of a plurality of packages by an accumulation conveyor. The drive controller is configured to determine a length of each of the packages and to coordinate driving of a number of zones needed to accommodate the package. For example, a sensor in each of the conveyor zones communicates blockage by the packages to the drive controller. The drive controller determines a sequence of blockage of the sensors in adjacent zones. Blockage of the sensor in an upstream zone before the sensor in a downstream zone indicates an oversized package that extends longer than a zone length of the downstream zone and into the upstream zone. The drive controller is configured to drive the downstream zone and upstream zone simultaneously when detecting the oversized package.

Abstract: A conveyor system that includes a zoned conveyor surface and a loading sensor. The loading sensor is configured to detect placement of a load into the zone. A loading timer is activated by loading detection by the sensor and while activated, a controller system halts movement of the zone. This stops movement of the zone, facilitating placement of the load in the zone. Also, a sensor blocked signal may be sent to the upstream zone to stop movement of any loads in the upstream zone into the zone while loading. Normal movement in the upstream zone is handled by triggering a travel timer for a predetermined period of time, during which the loading timer is overridden so that the upstream load travels normally downstream.
