A system for zero pressure accumulation on roller conveyors is described, addressing issues arising from variable article lengths. It dynamically adjusts accumulation zone behavior to prevent jams and maintain high density by measuring article length and coordinating zone release. The system handles articles that span multiple predefined zone lengths, ensuring continuous product flow without collisions or gaps that reduce throughput. Recovery from emergency stops is managed by re-evaluating article positions and zone states, enabling a safe restart of material flow. This arrangement improves efficiency in material handling operations with diverse article dimensions.

This disclosure describes a self-correcting belt tracking system designed for conveyor applications. It addresses the problem of conveyor belts wandering off-center, which leads to premature wear, edge damage, and potential operational failure. The system employs a pivoting idler roller assembly, whose angular position is controlled by an actuator in response to the belt's lateral position. Belt edge location is detected using a non-contact sensing array. A control algorithm calculates the required idler angle to steer the belt back to its central path, preventing sustained off-tracking and reducing maintenance requirements.
