1. A control device configured to control an automatic loading operation of a loading machine, the loading machine including a swing body that is configured to swing about a center thereof and a work equipment that is attached to the swing body and has a bucket, the automatic loading operation being configured to cause the bucket to move to a loading position above a transport vehicle and to perform a loading motion to the transport vehicle, the control device comprising a processor that is configured to:
generate an operation signal of the work equipment and the swing body for moving the bucket to the loading position based on receiving a start command of the automatic loading operation;
generate an operation signal for braking a swing of the swing body based on receiving a stop command of the automatic loading operation; and
generate an operation signal for raising the work equipment to thereby avoid contact between the bucket and the transport vehicle in response to receiving the stop command of the automatic loading operation while the swing body rotates toward the transport vehicle in a state in which a height of the bucket is lower than the loading position.
