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.

An operation abnormality detection method for detecting an operation abnormality in a molding device having a movable part includes: acquiring a prescribed measured value relating to operation of the movable part and calculating, as statistical information, an average value of prescribed information values based on the prescribed measured values: calculating a first threshold and a second threshold; acquiring a current measured value and comparing a current information value based on the current measured value with the greater of the first threshold and the second threshold; and issuing a warning if the current information value at least exceeds the greater of the first threshold and the second threshold.

A manufacturing apparatus and method for a resin container. The apparatus includes at least: a heating unit configured to heat a preform; a blow molding part configured to mold a plurality of the preforms into a container; and a conveyance member configured to convey the plurality of preforms that has been heated to the blow molding part. The conveyance member includes: a plurality of holding arms each configured to hold one of the plurality of preforms; a connecting member configured to connect together the plurality of holding arms at equal intervals; and a pitch changing mechanism configured to change a pitch between the plurality of holding arms, and the pitch changing mechanism includes a stopper mechanism configured to position the plurality of holding arms at a predetermined wide pitch when an interval of the holding arms is changed from a narrow pitch to the predetermined wide pitch.

The invention relates to a packaging method and to an associated packaging device (1) for packaging injection-molded plastic parts (2), which are pipette tips or medical reaction vessels, the injection-molded plastic parts (2) being arranged in cavity-pure subgroups (6) and then subjected to lateral inspection sub-subgroup (10) per sub-subgroup (10).
