The use of collaborative robots (Cobot) in palletizing is experiencing significant growth, becoming a striking trend in the wave of automation. There are multiple driving factors behind this growth, and it indicates a broad development prospect in the future.
Growth drivers
Labor shortage and rising costs:
Globally, especially in the manufacturing and logistics industries, there is an increasing shortage of manual laborers, and labor costs are rising. Palletizing, as a highly repetitive and physically demanding job, has become the first choice for “machine replacement”.
“Machine replacement” has become a major practical need in the manufacturing industry.
Unique advantages of collaborative robots:
Safety: Collaborative robots have functions such as collision detection and safe stop, and can work closely with humans without setting up safety fences to meet safe production requirements.
Flexibility and ease of deployment: Compared with traditional industrial robots, collaborative robots are usually lighter, easier to program and redeploy (usually only a few hours or even minutes), which makes them very suitable for multi-batch, small-batch production and scenarios where production lines need to be adjusted quickly. They can even be installed on carts for movement.
Small footprint: Collaborative robots usually occupy a small area, especially in space-constrained production environments.
Easy to operate: Usually equipped with an intuitive user interface and drag-and-drop teaching function, it lowers the threshold for operation and does not require advanced programming skills.
Fast return on investment: The relatively low initial investment and high efficiency improvement make collaborative robots have a faster return on investment cycle in palletizing applications.
Acceleration of e-commerce and intelligent logistics warehousing: The rapid development of the e-commerce industry has led to a surge in order volume, and the demand for warehouse automation and efficient product handling solutions has continued to increase.
The palletizing and depalletizing applications of collaborative robots in warehouses can effectively cope with the growing demand for order processing.
Technological progress: The load capacity and arm span of collaborative robots themselves are constantly improving. For example, collaborative robots with a load of 30KG have been launched, which can meet most of the palletizing needs of industries such as food, daily chemicals, logistics and warehousing.
The deep integration of AI vision, force control, AGV (automatic guided vehicle) and other technologies enables collaborative robots to achieve smarter, more accurate and more flexible operations in palletizing applications, such as 3D vision disordered depalletizing, automatic calculation and adaptive new product palletizing solutions.
The standard configuration of palletizing process packages and the popularization of graphical operation interfaces further simplify the deployment and configuration process.
Typical application scenarios
Food and beverage industry: The demand for collaborative palletizing robots accounts for more than 65%, especially for scenarios with high requirements for hygiene and flexible production.
Daily chemical industry: Palletizing of multiple categories of daily chemical products can greatly improve efficiency and storage capacity.
Logistics warehousing: Palletizing, depalletizing and sorting of goods, especially in meeting the flexible production needs of multiple batches and small batch orders.
Auto parts, 3C electronics, mechanical processing, home appliance manufacturing, pharmaceuticals and other industries: Widely used in palletizing, packing and other links at the end of the production line.
Challenges and Future Development
Despite rapid growth, collaborative robots still face some challenges in the field of palletizing, such as:
Palletizing of complex or irregular products: Despite the progress of vision systems, more advanced sensing and grasping technologies are still needed for materials with extremely irregular shapes, sizes or packaging.
Demand for larger loads and reach: Although there are large-load collaborative robots, traditional industrial robots still have advantages in palletizing tasks that are extremely heavy or require larger workspaces.
Integration complexity: Although a single collaborative robot is easy to deploy, it still requires professional system integration capabilities to seamlessly integrate it into a complex automated production line.
Future development trends:
Smarter palletizing: Combining AI, big data and machine learning to achieve adaptive, optimized and predictive maintenance of palletizing tasks.
Collaborative robots with higher loads and wider range: Meet the palletizing needs of more heavy industries and large materials.
Deep integration of human-machine collaboration: Collaborative robots will work more closely with human workers, taking on more repetitive and dangerous tasks, allowing humans to focus on more valuable work.
Modular and rapid deployment solutions: Further simplify the configuration and implementation of palletizing solutions and lower the threshold for use.
Integration with mobile platforms: Composite robots (AGV + collaborative robots) will be more widely used in mobile palletizing, achieving seamless integration of internal factory logistics and palletizing.
