Abstract
The enunciator system for an AGV includes a transmitter mounted on the AGV connected to an electrical control circuit having a plurality of individual switches operable to cause the transmitter to transmit a specific signal upon arrival of the AGV at predetermined locations along a circuitous route. Each location along the AGV route has identifier markings detectable by the AGV such that the AGV will stop for a predetermined period of time at each location as it travels along its route. If a switch for a specific location is actuated, the transmitter will transmit a signal to a receiver at that location which then triggers an audio or visual alarm at the location to alert a person at the location as to the arrival of an item on the AGV. After a predetermined period of time, the alarm will cease and the AGV will continue along its circuitous route. If the item is not removed from the AGV at the specified location, the AGV will continue along with the route until it arrives once again at the specified location at which time it will again trigger the alarm at that location, Because each specific location has its own independent receiver to receive an independent signal from the transmitter, more than one location may be specified for different items without triggering the alarms of undesignated locations.
