The AM-20 cobot palletizer series is a high-efficiency, flexible light-to-medium load palletizing solution designed for mainstream end-of-line packaging scenarios. Featuring a 20kg rated payload and a stable throughput of up to 12 cartons per minute, this series delivers outstanding working efficiency for daily packaging operations. It covers diversified application demands with three complete configurations: the AM-20-G for standard 1900mm stacking height, the AM-20-S supporting 2300mm high stacking for elevated palletizing requirements, and the AM-20 Ultra equipped with a 2100mm extended working reach and stacking height to expand horizontal operation coverage. All models in the series maintain ultra-high positioning accuracy of ±0.04mm, reliable IP54 industrial dust and water resistance, and a compact floor-saving footprint that adapts to most standard production line layouts. Adopting intuitive visual programming and supporting fast one-hour on-site commissioning, the series enables operators to complete pallet pattern setup quickly without professional robot expertise. It also supports flexible functions including single/double gripper switching and dual-product simultaneous stacking, making it a cost-effective and versatile automated palletizing choice for food, pharmaceutical and daily chemical industries.
