Loading machine control device and control method

1. A control device for controlling a loading machine including a swing body that swings around a center of swing and a work equipment that is attached to the swing body and has a bucket, the control device comprising:

an operation signal input unit that is configured to receive an input of a dumping operation signal and a loading command signal for causing the bucket to dump earth from an operator; and

an operation signal output unit that is configured to:

output an operation signal of the work equipment and the swing body for moving the bucket to a loading point in a case where the loading command signal is received,

prohibit an output of the dumping operation signal when the dumping operation signal is received, in a case where an azimuth direction in which the swing body faces is included in a first region from a starting point azimuth direction to a predetermined reference azimuth direction, the starting point azimuth direction being an azimuth direction in which the swing body faces when the loading command signal is received, and

output the dumping operation signal when the dumping operation signal is received, in a case where the azimuth direction in which the swing body faces is included in a second region from the reference azimuth direction to an end point azimuth direction which is an azimuth direction in which the swing body faces when the work equipment is positioned at the loading point.

2. The control device according to claim 1 , wherein the first region is a region where the work equipment and a loading object do not interfere with each other in a plan view from above.

3. The control device according to claim 1 , wherein the operation signal output unit outputs the operation signal of the work equipment for moving the work equipment to the loading point in a case of being included in the first region, and prohibits the output of the operation signal of the work equipment for moving the work equipment to the loading point in a case of being included in the second region.

4. A control device for controlling a loading machine including a swing body that swings around a center of swing and a work equipment that is attached to the swing body and has a bucket, the control device comprising:

an operation signal input unit that is configured to receive an input of a dumping operation signal and a loading command signal for causing the bucket to dump earth from an operator; and

an operation signal output unit that is configured to:

output an operation signal of the work equipment and the swing body for moving the bucket to a loading point in a case where the loading command signal is received, and

prohibit an output of the dumping operation signal when the dumping operation signal is received, in a case where an azimuth direction in which the swing body faces is included in a region from a starting point azimuth direction to a predetermined reference azimuth direction, the starting point azimuth direction being an azimuth direction in which the swing body faces when the loading command signal is received.

5. A control device for controlling a loading machine including a swing body that swings around a center of swing and a work equipment that is attached to the swing body and has a bucket, the control device comprising:

an operation signal input unit that is configured to receive an input of a dumping operation signal and a loading command signal for causing the bucket to dump earth from an operator; and

an operation signal output unit that is configured to:

output an operation signal of the work equipment and the swing body for moving the bucket to a loading point in a case where the loading command signal is received, and

output the dumping operation signal when the dumping operation signal is received in a case where an azimuth direction in which the swing body faces is included in a region from a predetermined reference azimuth direction to an end point azimuth direction which is an azimuth direction in which the swing body faces when the work equipment is positioned at the loading point.

6. A control method for controlling a loading machine including a swing body that swings around a center of swing and a work equipment that is attached to the swing body and has a bucket, the control method comprising the steps of:

receiving a loading command signal from an operator;

outputting an operation signal of the work equipment and the swing body for moving the work equipment to a loading point when the loading command signal is received;

receiving an input of a dumping operation signal for causing the bucket to dump earth from the operator; and

prohibiting an output of the dumping operation signal when the dumping operation signal is received in a case where an azimuth direction in which the swing body faces is included in a first region from a starting point azimuth direction to a predetermined reference azimuth direction, the starting point azimuth direction being an azimuth direction in which the swing body faces when the loading command signal is received, and

outputting the dumping operation signal when the dumping operation signal is received in a case where the azimuth direction in which the swing body faces is included in a second region from the predetermined reference azimuth direction to an end point azimuth direction which is an azimuth direction in which the swing body faces when the work equipment is positioned at the loading point.
