Swing arms are mainly used for label application, on the front of moving products on a conveyor. The AP4050 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, this system is simple, reliable and cost effective. Due to the moderate force of the pneumatic actuator, the AP4050 Swing Arm is intrinsically safe for the operators.
