Abstract
A display device causes a display unit to display a first graph showing the temporal change of a feature value of a physical quantity measured in each molding cycle of an injection molding machine and a second graph showing the temporal change of events that occurred in the injection molding machine, with the time axes of the first graph and the second graph being defined in the same direction on the same scale, based on cycle information indicating the molding cycle in which the feature value was measured and occurrence period information indicating the occurrence time period of the events.
Claims16
A display device for displaying an operation history of an injection molding machine, comprising:
- a first storage control unit configured to acquire a feature value of a physical quantity measured in each molding cycle of the injection molding machine, and store the acquired feature value in a storage unit in association with cycle information indicating the molding cycle in which the feature value was measured;
- a second storage control unit configured to acquire event information indicating content of each of events that have occurred in the injection molding machine, and store the acquired event information in the storage unit in association with occurrence period information indicating an occurrence time period of each of the events;
- and
- a display control unit configured to, based on the cycle information and the occurrence period information, cause a display unit to display a first graph showing temporal change of the feature value and a second graph showing temporal change of the events, with time axes of the first graph and the second graph being defined in a same direction on a same scale,
- wherein the display control unit is configured to display marks respectively indicating the events, in the second graph in a manner that the marks are selectable.
A display method for displaying an operation history of an injection molding machine, comprising:
- a first storing step of acquiring a feature value of a physical quantity measured in each molding cycle of the injection molding machine and storing the acquired feature value in a storage unit in association with cycle information indicating the molding cycle in which the feature value was measured;
- a second storing step of acquiring event information indicating content of each of events that have occurred in the injection molding machine and storing the acquired event information in the storage unit in association with occurrence period information indicating an occurrence time period of each of the events;
- and
- a displaying step of, based on the cycle information and the occurrence period information, causing a display unit to display a first graph showing temporal change of the feature value and a second graph showing temporal change of the events, with time axes of the first graph and the second graph being defined in a same direction on a same scale,
- wherein the displaying step displays marks respectively indicating the events, in the second graph in a manner that the marks are selectable.
