Abstract
An injection molding system includes an injection molding apparatus that performs injection molding with a die and a conveyor apparatus on one side of the injection molding apparatus that inserts the die into the injection molding apparatus, where the conveyor apparatus includes an actuator connectable to the die. The injection molding system also includes a die detection unit that detects the conveyed die, an actuator detection unit that detects a state of the actuator, and a controller that controls the conveyor apparatus to prohibit a conveying operation of the die based on detection results by the die detection unit and the actuator detection unit.
Claims18
An injection molding system, comprising:
- an injection molding apparatus configured to perform injection molding with a plurality of dies;
- a conveyor apparatus that includes an actuator that provides power to alternately convey a first die of the plurality of dies and a second die of the plurality of dies into the injection molding apparatus for injection of a molded material;
- a force detection sensor configured to detect a force applied to the actuator;
- a plurality of detection sensors for detecting at least one die of the plurality of dies;
- and
- a controller configured to control the conveyor apparatus to stop a conveying operation based on a detection result by the force detection sensor while the plurality of dies are moved by the actuator,
- wherein, when the first die is conveyed into the injection molding apparatus, the second die is simultaneously conveyed to a cooling position external to the injection molding apparatus,
- wherein, when the second die is conveyed into the injection molding apparatus, the first die is simultaneously conveyed to a cooling position external to the injection molding apparatus, and
- wherein, after finishing conveying the die into the injection molding apparatus, the controller prohibits further conveying operation based on a detection result of the die by each detection sensor of the plurality of detection sensors.
A method for injection molding using an injection molding system that includes a conveyor apparatus with an actuator configured to alternately convey a die into an injection molding apparatus, a plurality of detection sensors for detecting the die, and a controller, the method comprising:
- performing injection molding using the die and the injection molding apparatus;
- detecting, by at least one sensor of the plurality of detection sensors, a force applied to the actuator;
- and
- controlling the conveyor apparatus to stop a conveying operation based on a detection result by the at least one sensor while the die is moved by the actuator,
- wherein, after conveying the die into the injection molding apparatus, the controller prohibits further conveying operation based on a result of the detecting.
A method for manufacturing products using an injection molding system that includes a conveyor apparatus with an actuator configured to alternately convey a die into an injection molding apparatus, a plurality of detection sensors for detecting the die, and a controller, the method comprising:
- performing injection molding using the die and the injection molding apparatus;
- detecting, by at least one sensor of the plurality of detection sensors, a force applied to the actuator;
- and
- controlling the conveyor apparatus to stop a conveying operation based on a detection result by the at least one sensor while the die is moved by the actuator,
- wherein, after conveying the die into the injection molding apparatus, the controller prohibits further conveying operation based on a result of the detecting.
