Title:
射出成形機の異常検出装置
Document Type and Number:
Japanese Patent JP6378236
Kind Code:
B2
Abstract:
An abnormality detection device includes a servo CPU; a physical quantity detection unit which detects a physical quantity such as a load applied on a servo motor which operates a movable part included in an injection molding machine. The abnormality detection device further includes a first storage unit directly readable/writable by the servo CPU; and a second storage unit not directly readable/writable by the servo CPU. A reference physical quantity is stored in the first and second storage units. The servo CPU outputs an instruction for stopping or decelerating the movable part in response to a first physical quantity deviation, which is a deviation between a reference physical quantity read from the first storage unit and a current physical quantity, or a second physical quantity deviation, which is a deviation between a reference physical quantity read from the second storage unit and a current physical quantity, exceeds a threshold value.
