Loading machine control device and control method

Provided is a loading machine control device. When a loading instruction signal is received, the control device outputs operation signals for a machine and a slewing structure for moving the machine to a loading point. When an excavation operation signal is received in the case where the facing orientation of the slewing structure is included in a first region from a start orientation which is a facing orientation of the slewing structure faces when the loading instruction signal is received to a predetermined reference orientation, the control device does not output an excavation operation signal. When an excavation operation signal is received in the case where the facing orientation of the slewing structure faces is included in a second region from a reference orientation to a finish orientation which is a facing orientation of the slewing structure when the machine is located at a loading point, the control device outputs an excavation operation signal.
