## Abstract

A work system includes a mounting system which mounts a component on a board and an unmanned conveyance system having an unmanned conveyance vehicle. The unmanned conveyance system includes a first notifier which notifies the mounting system of an arrival notification indicating that the unmanned conveyance vehicle transfers the feeder carriage to a position where an operation of connecting the feeder carriage to the base starts, and a first processor which causes the unmanned conveyance vehicle to travel in a direction away from the base upon receiving, from the mounting system, a connection completion indicating that a connection of the feeder carriage is completed. The mounting system includes a second processor which causes the connection mechanism to connect the feeder carriage upon receiving the arrival notification, and a second notifier which notifies the unmanned conveyance system of the connection completion upon being informed of completion of the connection.

## Claims

### Claim 1

A work system comprising:
a mounting system including a base having a connection mechanism, a feeder carriage being detachable from the base, and a mounting-system processor configured to perform mounting operations that cause the connection mechanism to release a connection of the feeder carriage,
an unmanned conveyance system including an unmanned conveyance vehicle having a capturing mechanism and a conveyance-system processor in communication with the mounting system, the conveyance-system processor configured to perform conveyance-system operations causing the capturing mechanism to capture the feeder carriage and the unmanned conveyance vehicle to travel in a direction away from the base, wherein the conveyance-system processor starts to perform the conveyance-system operations when the connection mechanism completes releasing the connection of the feeder carriage.

### Claim 2 (depends on 1)

The work system of claim 1, wherein:
the mounting-system operations further comprise identifying, using an input device, the feeder carriage being required to be removed by the unmanned conveyance vehicle, and the conveyance-system operations further cause the unmanned conveyance vehicle to move to the identified feeder carriage attached to the base.

### Claim 3 (depends on 1)

The work system of claim 1, wherein the feeder carriage includes a holding member configured to hold a replacement table.

### Claim 4 (depends on 3)

The work system of claim 3, wherein:
the mounting-system operations further comprise determining that the replacement table is required to be removed based on set-up changing information, and
when the replacement table is ready to be removed, the conveyance-system processor starts to perform the conveyance-system operations causing the replacement table to be removed by the unmanned conveyance vehicle.
