Article delivery system and method

An article delivery system for delivering an article used in production of a board on which a component is mounted between an automated guided vehicle configured to convey the article and a storage section configured to store the article, the system comprising:

• a first electric conveyor provided on a side of the automated guided vehicle, and configured to deliver the article between the first electric conveyor and the storage section;
• a first communication module provided on the side of the automated guided vehicle, and configured to transmit a first signal to a side of the storage section;
• a first emergency stop switch provided on the side of the automated guided vehicle;
• a second electric conveyor provided on the side of the storage section, and configured to deliver the article between the second electric conveyor and the first electric conveyor of the automated guided vehicle;
• a second communication module provided on the side of the storage section, and configured to transmit a second signal to the side of the automated guided vehicle;
• a second emergency stop switch provided on the side of the storage section;
• a conveyor control device provided on the side of the automated guided vehicle, connected to the first communication module, the conveyor control device including a processor configured to control the first electric conveyor;
• and
• a control device provided on the side of the storage section and connected to the second communication module, the control device including a processor configured to control the storage section, wherein
• the first and second communication modules are configured to exchange signals with each other,
• power supply to the first electric conveyor is shut off and the first signal from the first communication module changes in response to operation of the first emergency stop switch,
• power supply to the second electric conveyor is shut off and the second signal from the second communication module changes in response to operation of the second emergency stop switch,
• the power supply to the second electric conveyor is shut off in response to a change in the first signal from the first communication module,
• the power supply to the first electric conveyor is shut off in response to a change in the second signal from the second communication module, and
• even when the power supply to the first and second electric conveyors is shut off in response to the operation of the first or second emergency stop switch, power supply to the conveyor control device and the control device is continued such that communication between the conveyor control device and the control device is continued via the first and second communication modules.
