Abstract
A numerical controller instructs a robot or an automated machine (external device), in relation to a main task for which a retrying operation thereof has occurred, to execute, instead of or in addition to the main task, a sorting task to distinguish an exception molded product, which was produced from a time when a determination result became successful, and until a physical quantity to be measured lies within a management range, or until a stand-by time elapses, from a normal molded product produced before the occurrence of the retrying operation.
Claims6
An injection molding system comprising:
- an injection molding machine having a function of producing a molded product for each of respective molding cycles by injection molding, and having a sensor that measures a physical quantity to be managed;
- a robot capable of carrying out at least one main task involved in operation of the injection molding machine during the molding cycles;
- and
- a controller that comprises a processing device programmed to instruct the robot to carry out a determination in relation to success or failure of the main task executed by the robot, and to retry, when a determination result is a failure, the main task until the determination result becomes successful;
- wherein the processing device is further programmed to determine that a sorting task is needed that distinguishes a molded product produced from a time when the determination result with respect to the main task that the robot has been instructed to retry became successful until the physical quantity lies within a management range, or from said time until a predetermined stand-by time elapses, from molded products produced before the occurrence of the retrying operation,
- wherein the processing device is further programmed to instruct the robot to execute any one of a task of releasing, at a different sorting location compared to the molded products produced before the occurrence of the retrying operation, the molded product for which it is determined that the sorting task is needed, a task of marking, or a task of discarding.
An injection molding method in which there is used an injection molding system configured to include an injection molding machine having a function of producing a molded product for each of respective molding cycles by injection molding, and having a sensor that measures a physical quantity to be managed, and a robot capable of carrying out at least one main task involved in operation of the injection molding machine during the molding cycles, the injection molding method of each of the injection molding cycles comprising:
- a determining step of determining success or failure of the main task executed by the robot;
- a retrying step of executing, in the case that a determination result is a failure, a retrying operation of the main task by the robot until the determination result becomes successful;
- and
- an executing determining step in which it is determined that a sorting task is needed that distinguishes a molded product produced from a time when the determination result with respect to the main task that the robot has been instructed to retry became successful until the physical quantity lies within a management range, or from said time until a predetermined stand-by time elapses, from molded products produced before the occurrence of the retrying operation,
- a step of the robot executing any one of a task of releasing, at a different sorting location compared to the molded products produced before the occurrence of the retrying operation, the molded product for which it is determined that the sorting task is needed, a task of marking, or a task of discarding,
- wherein, during at least one of the injection molding cycles, the determining step determines failure of the main task executed by the robot.
