最近, we received on-site photos from a customer’s single column rotary palletizer. The product is 6 kg boxes of honey water beverage, with a production capacity of 410 boxes per hour. The pallet pattern is 16 boxes per layer, stacked 6 layers high. The core highlights of the palletizing solution we designed for this customer are: a single column rotary main unit + dual-station pallet positions + two stretch wrappers working in tandem, coupled with a unique “two‑box‑one‑grip” pick‑and‑place design. This perfectly meets the customer’s requirements for high throughput and high stacking, also ensures seamless integration with the production line.
Q1: Why choose a single column rotary palletizer and design it with “two-box-one-grip”?
あ: The single‑post structure has a small footprint and offers high rotational and lifting speeds. When handling 6‑kg boxes, the gripping strategy is critical. Picking one box at a time would make the mechanical movements too frequent, making it difficult to break through the bottleneck of 410 boxes/hour. Picking a full layer at once would place excessive demands on the gripper’s load capacity and the rigidity of the cartons, and would also be susceptible to uneven spacing between incoming boxes. したがって, we adopted the optimal solution of “two‑box‑one‑grip”: it strikes the best balance between pick frequency and load, halves the number of mechanical actions, significantly improves cycle time, and results in a lighter, more agile gripping mechanism—while also reducing both initial equipment costs and long‑term maintenance expenses.
第2四半期: How is the ultra‑high throughput of 410 boxes/hour achieved with “two‑box‑one‑grip” and the dual‑station design?
あ: The key lies in the perfect use of “time overlap.” With two boxes picked each time, each layer of 16 boxes requires only 8 movements; 6 layers needs just 48 movements to complete the stack—dramatically reducing the number of actions. Combined with the dual‑station layout, when station A finishes stacking 6 レイヤー, the machine quickly rotates to station B to continue the “two‑box‑one‑grip” operation. 同時に, one of the two stretch wrappers starts online wrapping of the already‑stacked high pallet at station A. This “parallel processing, zero‑waiting” relay mode ensures a continuous and stable output of 410 boxes/hour.
Q3: Why must equip two stretch wrappers? Isn’t one enough?
あ: A single stretch wrapper would force the palletizer to stop and wait during wrapping, effectively cutting throughput in half. We equip two stretch wrappers to form a “perfect closed loop” with the dual stations. While the palletizer is busy with “two‑box‑one‑grip” at station B, the wrapper at station A is working. When station B finishes stacking, station A is ready to go. The two machines alternate seamlessly, eliminating wrapping wait time, unlocking the “last mile” of a fully automated production line.
Q4: と 16 boxes per layer and 6 レイヤー, how do you ensure the heavy stacks do not collapse?
あ: For the “two‑box‑one‑grip” motion path, we custom‑designed a dual‑box servo gripper. Each pick‑and‑place ensures that the load is perfectly centered and symmetrical, enabling smooth high‑speed rotation and lifting without the offset or collision risks associated with single‑box picking. Moreover, after the 6‑layer tall stack is pushed into the stretch wrapper, the two wrappers immediately apply high‑tension 360° film wrapping to reinforce the load, locking all 96 boxes firmly into a single, stable unit that can easily withstand the rigors of long‑distance transportation.
Q5: What core value does this “two‑box‑one‑grip” combined solution bring to the customer?
あ:
Ultimate cost‑performance: Compared to full‑layer gripping, “two‑box‑one‑grip” greatly reduces gripper complexity and hardware costs. Compared to single‑box picking, it substantially boosts efficiency. It is the “golden” design with the highest return on investment.
Absolute reliability: The single column all‑mechanical rotary structure, paired with mature servo systems, ensures extremely low failure rates even under 24/7 high‑load operation, and is very easy to maintain.
Space and labor savings: The equipment has a minimal footprint and completely replaces the heavy manual palletizing and handling work that would otherwise require 3–4 operators. Only one person is needed to oversee the two stretch wrappers, significantly improving the workshop working environment.
