Abstract
A movement processing unit generates a work equipment operation signal for moving a bucket to a loading point and a swing operation signal related to a target swing speed, based on a command for starting an automatic movement of the bucket. A target speed changing unit changes the target swing speed so that the work equipment does not interfere with the loading target during a swing of a swing body.
Claims6
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.
A control method for 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 method comprising:
- generating
- 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 generating the work equipment operation signal and the swing operation signal being 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;
- determining whether or not the work equipment interferes with the loading target by the swing operation signal during swinging of the swing body;
- and
- changing the target swing speed when the interference determination unit determines that the work equipment interferes with the loading target.
