Abstract

A loading machine includes a swing body and work equipment with a bucket. A control device of the loading machine includes a loading target specifying unit that specifies a position and shape of a loading target, an avoidance position specifying unit, and a movement processing unit. The avoidance position specifying unit specifies an interference avoidance position based on the position and shape of the loading target. The movement processing unit outputs an operation signal to drive only the swing body until the bucket reaches the interference avoidance position from a loading position above the loading target, to cause the bucket to move to the interference avoidance position. The movement processing unit outputs an operation signal to drive the swing body and the work equipment after the bucket has reached the interference avoidance position, to cause the bucket to move to an excavation position above an excavation target.
