Multi-Pallet Support

Unlike traditional systems limited to one pallet at a time, dPally excels at managing one or two pallets simultaneously, even with varying sizes.

For high-volume businesses dealing with multiple pallets of different sizes, dPally offers a significant advantage. It streamlines depalletizing, reducing downtime and boosting productivity. Handling one or two pallets optimizes throughput and minimizes robot inactivity, ensuring a smooth flow of products.

This feature allows businesses to consolidate operations and streamline workflows, resulting in cost savings. Industries with high-volume depalletizing requirements benefit from this practical and efficient solution, which ensures continuous operations, improved productivity, and reduced equipment needs.

Dual Product Mode

A remarkable feature of dPally is its ability to depalletize in Dual Product Mode, meaning that the software can simultaneously transfer boxes from two pallets onto two conveyor belts. The feature is a remarkable capability that sets it apart as an efficient and high-productivity depalletizing system. 

By handling two pallets at once, dPally optimizes throughput and reduces time, maximizing the overall efficiency of the depalletizing process. This results in a more continuous flow of products, reducing bottlenecks and streamlining material handling operations.

The Dual Product Mode enables businesses to handle higher volumes of products within the same time frame, leading to increased productivity and output, which will be especially beneficial for industries with high-demand production schedules or time-sensitive operations. In addition to the productivity benefits, the Dual Product Mode can also lead to cost savings, as businesses may reduce the need for additional depalletizing equipment or labor. Overall, dPally’s Dual Product Mode will significantly enhance productivity and material flow. 

Effortless Pallet Height Handling

Many depalletizing systems may struggle to handle tall pallets, leading to inefficiencies and potential product damage. However, dPally’s advanced technology and design allow the robot to manage more elevated loads smoothly, ensuring a seamless and reliable depalletizing process. 

Depending on the size and arrangement of the boxes, dPally can handle items with heights up to approximately 2.5 meters. A standard setup of a 900 mm-1400 mm lifting column attached to a UR10 and UR20 further contributes to dPally’s effortless pallet height handling. This lifting column provides the necessary support and stability to accommodate most pallet sizes.

While effortlessly handling pallets above two meters in height, dPally offers businesses greater flexibility and adaptability in depalletizing operations. This feature reduces the risk of product damage during the depalletizing process.

Boundaries of dPally – and how to overcome them

Life is not all about benefits – and dPally is no exception. Although it offers impressive capabilities, certain limitations must also be considered, as well as the strategies to overcome them:

Pallet Accuracy

Pallets may not be perfectly aligned during stacking, loading, or transport because of slight lateral variations. The lateral positioning can still be acceptable, and the lateral tolerance is the allowance for these minor deviations. It limits how much the items can deviate from an ideal, perfectly aligned position on the pallet while still being considered acceptable and safe for depalletizing. 

To address this challenge, dPally uses a controlled pick-up strategy, leveraging the e-Series robots’ force sensors, ensuring accurate depalletizing even with height and lateral tolerance challenges during transportation, making dPally more advanced than its “sibling“, Pally.

By implementing the controlled pick-up strategy, dPally enables the robot gripper to detect and assess the allowable margin of error in positioning or aligning items during the pick-up process. With its advanced technological capabilities, dPally ensures precise and accurate pick-up of boxes, even in slight variations in the horizontal alignment of items on the pallet.

Speed Consideration

When using Force Mode to pick up items during depalletizing, it may slow down the overall process, which can affect the number of boxes that can be depalletized in a given time frame.

However, with the use of dPally, speeds of up to 30 cases per minute (CPM) can be achieved, which is significantly higher than what is possible without dPally or its competitors.

Reach Constraints

Reach Constraints refer to a limitation in the range of motion or distance the robotic arm can generally extend to access objects on a pallet. When picking up boxes, the robot may need to raise them to avoid obstacles before placing them on the conveyor belt.

With dPally’s standard setup, which includes a lifting column ranging from 900mm to 1400mm, it can even depalletize high pallets that are roughly around 2.5 meters high, depending on the boxes’ size and pattern. This setup determines the vertical distance that the robot can reach when picking up boxes.

Gripper Size and Orientation

Gripper Size Consideration:

It’s crucial to avoid using a gripper larger than the boxes handled in the depalletizing process. If the gripper is too big, it may not fit properly around the individual boxes, and as a result, it could grip multiple boxes at once or grip parts of neighboring boxes. 

The gripper size should be proportional to the dimensions of the box. Additionally, the gripper should be able to activate different zones during the depalletizing process.

Gripper Orientation:

In addition to selecting an appropriately sized gripper, the orientation of the gripper while approaching and gripping the boxes is critical. We recommend letting dPally define the gripper orientation automatically rather than setting it manually.

By allowing dPally to determine the orientation of the gripper, the robot can approach the boxes as efficiently and effectively as possible. The software’s algorithms and logic have been optimized to understand the dimensions and positions of the boxes, allowing the robot to pick them up accurately and securely, minimizing the risk of misalignments or unintended box movements during the pick-up process.

By letting dPally handle the gripper orientation, the depalletizing process becomes more streamlined, reliable, and less prone to errors caused by manual adjustments.

dPally’s niche

Although dPally is an ideal solution for small and medium-sized enterprises that use collaborative robots to improve safety and efficiency, larger logistics companies may require even greater customization and flexibility. 

These companies often have unique and specific needs that demand highly customizable depalletizing solutions. They may handle unconventional pallet configurations, non-standard packaging, or fragile items that require specialized handling. Therefore, dPally’s standardized capabilities on a UR collaborative robot may provide a different level of flexibility and customization than these companies need.
