Swing arms applicators are mainly used for label frontal application on products moving on a conveyor. The swing arm is driven by a robust pneumatic rotary cylinder, which brings the tamp plate at the desired angle. A proximity sensor will release the label as close as possible to the product, for a reliable and accurate positioning. Thanks to its clever mechanical design and advanced electronics and firmware, the AP122 Swing arm is simple, reliable and cost effective. Due to the moderate force of the pneumatic actuator, this system is intrinsically safe for the operators.
