1. A control device for controlling a loading machine including a swing body that swings about a swing center and work equipment that is attached to the swing body and has a bucket, the control device comprising:
a processor including
a movement processing unit that generates
a work equipment operation signal in order to move the bucket to a loading point, and
a swing operation signal related to a target swing speed,
the work equipment operation signal and the swing operation signal being generated based on a command for starting a moving operation in order to move the bucket to the loading point without an operation of an operator;
an interference determination unit that determines whether or not the work equipment interferes with the loading target by the swing operation signal during swinging of the swing body; and
a target speed changing unit that changes the target swing speed when the interference determination unit determines that the work equipment interferes with the loading target.
