When considering intelligent logistics upgrades for a carton plant, the palletizing of board bundles is often the most critical link for equipment stability and efficiency. This dual-station column rotary palletizer, equipped with custom integrated gripper, perfectly meets the demanding requirements of a capacity of 350 bundles/hour with stacking heights of up to 16 layers.
Q1: Why does the dual-station design achieve efficient and stable output of 350 bundles/hour?
A: Traditional single-station robots have to wait for the forklift to return before starting the next cycle. Dual‑station means when one pallet is full, the machine can switch immediately to an empty pallet and continue stacking. This seamless handover ensures that the high‑frequency rhythm of 350 bundles/hour is no longer limited by equipment response time. And even during long‑duration operation with 16‑layer high stacks, it maintains zero errors.
Q2: For 8–15 kg bundles picked one at a time, how does the custom gripper ensure stability?
A: Weight is a major challenge in palletizing. We adopt a mechanical servo-driven integrated gripper, with special load-strengthening design tailored to the characteristics of corrugated board. The gripper’s load capacity far exceeds the single-bundle requirement of 15 kg, providing ample safety margin.
In practice, the clamp‑style design, combined with photoelectric encoder sensing, ensures that heavy bundles are always firmly locked during high‑speed rotation and movement—no clamping deviation or slippage—so that the foundation of the 16‑layer high stack remains solid.
Q3: What challenges does a stack pattern of 3 bundles per layer and 16 layers impose on the equipment?
A: The challenges lie in motion accuracy and mechanical stability. Stacking 16 layers requires extremely high positioning accuracy in the vertical (Z) axis. The levelness error for each layer must be controlled within millimeters, otherwise the stack risks collapse.
Our system achieves precise positioning through a Z‑axis servo motor combined with a lifting gearbox and four‑axis coordinated motion. The counterweight effectively balances the weight of the column, reducing energy consumption, ensuring that even during 16‑layer stacking, operation remains smooth and steady.
Q4: What tangible production line benefits can this equipment bring to a carton plant?
A: Compared with traditional manual handling, the benefits are immediately visible. In terms of capacity, the robot’s 24/7 continuous operation provides stability that manual labor cannot match, and its efficiency far exceeds conventional average speeds.
In terms of space and flexibility, the column design occupies a smaller footprint, making it ideal for compact workshops.
