Abstract
A vibration sensor detects first data of a first component group and second data of a second component group. An injection molding machine performs diagnosis processing for diagnosing the first component group based on the first data in an injection mode and performs diagnosis processing for diagnosing the second component group based on the second data in a plasticization mode.
Claims15
An injection molding machine comprising:
- a first component;
- a second component different from the first component;
- a controller configured to drive the first component and the second component;
- and
- a first sensor configured to detect first data of the first component and second data of the second component, wherein
- the controller is configured to operate the injection molding machine using one of a plurality of modes including a first mode and a second mode,
- the first mode is a mode in which the first component is driven but the second component is not driven,
- the second mode is a mode in which the second component is driven but the first component is not driven, and
- the controller being further configured to:
- perform first diagnosis processing including at least one of abnormality detection and lifetime prediction of the first component based on the first data detected in the first mode, and
- perform second diagnosis processing including at least one of abnormality detection and lifetime prediction of the second component based on the second data detected in the second mode.
A method of diagnosing an injection molding machine, the injection molding machine including a first component, a second component different from the first component, and a first sensor that is configured to detect first data of the first component and second data of the second component, a mode of the injection molding machine including a first mode in which the first component is driven but the second component is not driven and a second mode in which the second component is driven but the first component is not driven, the method comprising:
- performing first diagnosis processing including at least one of abnormality detection and lifetime prediction of the first component based on the first data detected in the first mode;
- and
- performing second diagnosis processing including at least one of abnormality detection and lifetime prediction of the second component based on the second data detected in the second mode.
