Bottle Preform Loader

The challenge was to design a mechanism to transfer the injection molded preforms into a blow molding machine. The preforms, however got stacked automatically due to their geometry. To solve that issue the following mechanism was devised. This is only a conceptual model. The solution that came to my mind can be seen in the animation below. Notable parts of the design include linear and rotary pneumatic actuators, ball screws and stepper motors.
