RUNMA swing robot arms have four pneumatic-driven axes of motion. The horizontal axis pulls the runner and parts away from the mold. The vertical axis lifts the runner/parts out of the mold area. The swing axis pivots the arm over the safety gate to outside of the injection molding machine where the runner and parts are released after the arm re-extends. In addition, the standard wrist axis on the arm rotates the gripper to enable orientation of runner and parts. The RUNMA swing robot arms offer the fastest take-out times available for sprue separation and parts removal. The self-lubricating pneumatic drive system ensures low maintenance, exceptional stability and reliability. The swing robot arms are constructed on modular principles to ensure high precision and lightness. The main arm rides vertically on a linear slide rail and slides horizontally on two roller guide-ways; no maintenance is required and smooth running and the elimination of play and slack is ensured. Travel cushions on the vertical axis minimize vibration and ensure smooth deceleration; hydraulic shock absorbers are fitted on the crosswise axis for efficient damping. For maximum flexibility the arm can be easily adjusted to release runner and parts at the operator or the rear side of the machine. The swing angle can be freely adjusted between 60 to 90 degrees through a positive, but easily adjusted location fitting on the cylinder-driven oscillating arm. The manual clamp system on the swing robot arms allows them to swing clear of the mold area in seconds without the use of any tools. The built-in ratchet mechanism, which controls motion of the robot arm out of the mold area, enables easy mold changes or maintenance.
