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.
Claims8
An injection molding system comprising:
- an injection molding machine having functions of producing a molded product for each of respective molding cycles by injection molding, and measuring 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 adapted 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 the main task when the determination result is a failure;
- wherein the controller instructs the robot or an external device, in relation to the 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 a molded product, which was produced from a time when a determination result became successful, and until the physical quantity to be measured lies within a management range, or until a stand-by time elapses, from molded products produced before the occurrence of the retrying operation.
An injection molding method in which there is used an injection molding system configured to include an injection molding machine having functions of producing a molded product for each of respective molding cycles by injection molding, and measuring 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 comprising:
- a determining step of determining success or failure of the main task executed by the robot;
- a retrying step of executing a retrying operation of the main task by the robot in the case that the determination result is a failure;
- and
- an executing step in which, in relation to the main task for which a retrying operation thereof has occurred, the robot or the external device executes, instead of or in addition to the main task, a sorting task to distinguish a 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 molded products produced before the occurrence of the retrying operation.
