Practical Guide to Multi-Pick, Multi-Place, and Palletizing Configuration for Collaborative Palletiz

2026-04-22

Collaborative palletizing robots are widely used in modern packaging lines due to their flexibility, safety, and adaptability to different production requirements. One of the most valuable capabilities in real applications is the integration of multi-pick and multi-place functions, which allows the robot to handle multiple cartons within a single working cycle. This approach significantly improves efficiency, reduces cycle time, and enhances overall line performance.

Multi-pick functionality enables the robot to pick several boxes simultaneously by using a multi-suction cup end effector. Each suction cup is typically controlled independently, allowing the system to adapt to different product quantities and layouts. To ensure stable operation, the number of suction cups configured in the system must match the actual hardware, and each suction unit should be connected to a dedicated control valve. The arrangement of suction cups along the robot axis also plays an important role in maintaining balanced load distribution during picking.

In practical applications, the system determines how many boxes to pick based on the predefined configuration and the incoming product layout. For example, when multiple boxes arrive in a grouped formation on a conveyor, the robot can activate corresponding suction cups to pick them in a single motion. This reduces repetitive movements and improves throughput. At the same time, the orientation of the boxes on the conveyor must be consistent with the system settings, whether horizontal or vertical, to avoid positioning errors.

After picking multiple boxes, the robot can either place them simultaneously or distribute them in sequence according to the palletizing pattern. Sequential placement is often used when different orientations or positions are required within a single layer. In such cases, careful attention must be given to the rotation direction of the boxes to prevent deformation or interference. Proper coordination between motion trajectory and placement order ensures stable stacking and avoids collisions during operation.

Palletizing configuration is another critical factor affecting system performance. Most systems allow the use of predefined templates as well as manual adjustment of box positions. Operators can move, rotate, and align boxes within the interface to create the desired stacking pattern. A common practice is to begin palletizing from the reference point of the pallet and follow a consistent sequence, which helps maintain positioning accuracy. Staggered stacking patterns are often preferred because they improve the structural stability of the load.

Accurate coordinate settings and entry point adjustments are essential for precise placement. Entry point compensation allows the robot to fine-tune its approach position relative to the pallet coordinate system. By adjusting offset values in different directions, the system can correct minor deviations and ensure that each box is placed exactly as intended. This becomes particularly important when dealing with different pallet sizes or when switching between production formats.

Teaching pick points is a fundamental step in system setup. The robot is manually guided to a position directly above the box, and this position is recorded as the reference point for picking. In systems with multiple conveyors or different product types, separate pick points must be defined and correctly linked to their respective palletizing configurations. Consistency between pick points and pallet positions is necessary to maintain smooth and reliable operation.

Safety considerations remain essential throughout the configuration and operation process. Before starting the system, the working area should always be checked to ensure that no personnel or obstacles are present. During commissioning, it is recommended to operate the robot at reduced speed to verify motion paths and placement accuracy. Collision detection functions should be enabled, with sensitivity adjusted according to the actual load conditions. Although collaborative robots are designed for safer human interaction, additional safety measures such as barriers or sensors may still be required depending on the application.

During commissioning, all input and output signals should be verified, including sensors and control components. The alignment between the pallet and the robot coordinate system should also be confirmed. Running the system at a lower speed initially helps identify potential issues and allows for adjustments before full production begins. Once stable operation is achieved, parameters such as speed and motion efficiency can be gradually optimized.

The effective use of multi-pick and multi-place functions, combined with accurate palletizing configuration, enables collaborative robots to deliver high efficiency and consistent performance. With proper setup and adjustment, these systems can adapt to a wide range of packaging scenarios while reducing manual labor and improving operational reliability.
