SPRUE PICKER ROBOT

The sprue picker, a simple pick-and-place robotic device was intended as a low cost method of sprue removal or part and runner separation in the injection molding process. In most cases the low cost of these sprue pickers is maintained by employing a pneumatic motion system as the basis for their design. However, this design configuration provides a low cost robot at the expense of system durability, accuracy, speed and functionality. These desirable and needed features, inherent to the servo driven motion systems, seem unattainable in the present environment of cost conscious sprue picker applications
