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.
