Work system and feeder carriage transfer method

A work system comprising:

• a mounting system configured to mount a component on a board;
• and
• an unmanned conveyance system having an unmanned conveyance vehicle,
• wherein the mounting system includes:
• a base having a board positioner configured to position the board;
• a feeder carriage attachable to and detachable from the base;
• a connection mechanism configured to connect the feeder carriage to the base;
• a carriage detection sensor configured to detect whether or not the feeder carriage is located at a position where the feeder carriage is connectable by the connection mechanism,
• a part feeder attached to the feeder carriage and configured to supply the component in a state where the feeder carriage is connected to the base;
• and
• a mounting head configured to mount the component supplied by the part feeder on the board positioned by the board positioner,
• wherein the unmanned conveyance system includes:
• a first notifier configured to notify the mounting system of an arrival notification indicating that the unmanned conveyance vehicle transfers the feeder carriage scheduled to be connected to the base to a position where an operation of connecting the feeder carriage to the base starts;
• and
• a first processor configured to:
• cause the unmanned conveyance vehicle to travel so as to move the feeder carriage to the position where the feeder carriage is connectable by the connection mechanism upon receiving, from the mounting system, a connection permission of permitting a connection of the feeder carriage to the base, and
• cause the unmanned conveyance vehicle to travel in a direction away from the base upon receiving, from the mounting system, a connection completion indicating that the connection of the feeder carriage is completed, and
• wherein the mounting system further includes:
• a second processor configured to notify the unmanned conveyance system of the connection permission upon receiving the arrival notification, and
• after the notification, operate the connection mechanism to connect the feeder carriage to the base upon detecting the feeder carriage by the carriage detection sensor;
• and
• a second notifier configured to notify the unmanned conveyance system of the connection completion upon being informed of completion of the connection.
