Robotic palletizer is a kind of object that has been loaded into the container, according to a certain arrangement of yard in the pallet, pallet board (wood, plastic) on the machine. In use, the robot palletizer can arrange the objects (e.g. boxes, bags, etc.) into different stacks according to a pre-programmed program for automatic stacking, and then push them out for forklift transportation to the warehouse for storage.
Palletizing robots can be integrated with any production line to provide intelligent, robotic, and networked production sites, which can realize the palletizing logistics for a wide variety of operations in the chemical, beverage, and food industries, and are widely used in cartons, plastic boxes, bottles, bags, drums, film packaged products and filled products.
How Robotic Palletizing Works?
Robotic palletizing is divided into several main steps:
1. Product Identification: After being transported on the conveyor belt, products are transferred onto a robotic arm which uses sensors and vision systems to locate them and identify any items within its working range.
2. Pick and Place: The Robotic Palletizer picks up products and places them onto a pallet in sequence until the pre-defined stacking pattern has been accomplished.
3. Layer formation: The robot palletizer arranges the products in a specific pattern to form a stable layer on the pallet.
4. Pallet exchange: When the pallet is full, the system automatically removes the full pallet and brings an empty pallet to continue the operation.
The History of Robotic Palletizers
Robotic palletizing dates back decades to when industrial robots first made an appearance in the early 1960s. Due to limited technological innovation at that time, robotic systems were very basic at performing basic tasks such as welding, painting and assembly; manually operated palletizers still dominated this task.
As time passed and technology evolved, robotic palletizers became increasingly complex and versatile. Beginning in the 1980s when automated equipment designed specifically for palletizing first appeared – such as palletizers and conveyor systems. After their popularity had grown substantially due to computerized control systems in the 90s making robotic control systems simpler to program as well as flexible applications, robotic palletizing robots eventually came equipped with multiple gripping methods so as to adapt easily to products of different shapes, weights, materials or shapes.
Robotic palletizers have quickly become an indispensable asset to numerous industries today, with modern versions often including features such as vision systems and sensors to automate identification, positioning and quality inspection resulting in greater operational flexibility and accuracy across a broad spectrum of applications.
Advantages of Robotic Palletizers
- Increases production capacity: Robotic palletizers can operate non-stop and are much more efficient than manual palletizers.
- Accuracy: Robotic Palletizing accurately stacks products for easy subsequent transportation and reduces the risk of product damage.
- Cost savings: In the long run, robot palletizers not only save labor costs, but also significantly increase production efficiency.
- Consistency and precision: Robots maintain consistent performance, reducing common errors in manual palletizing.
- Flexibility: Modern robotic palletizers offer excellent flexibility, easily being programmed to support various product types and palletizing patterns.
- Safety: Automated processes reduce injuries associated with manual processes by drastically decreasing risk factors associated with manual palletizing tasks.
Common Robotic Palletizer System Components
1. End-of-Arm Tooling (EOAT): EOAT refers to an attachment at the end of a robot palletizer which interacts directly with products and is responsible for performing pick and place tasks accurately and quickly, guaranteeing accurate handling and efficient product distribution. EOATs can be modified according to specific applications or product types as required.
2. Control Cabinet: This computer and its accompanying software ensure that a robot operates smoothly and accurately, keeping every moving part under its direct control.
3. Conveyor System: A conveyor system plays an essential part in providing access to palletizing areas from robotic arms.
4. Peripheral Equipment: Peripheral equipment serves to safeguard operations by restricting who enters an operating area and to provide workers with an uninterrupted working environment. It plays a pivotal role in protecting workers while creating an ideal working atmosphere.
5. Pallet: Robot palletizers place products on a tray arranged in a certain configuration so that they can be grouped and stacked for subsequent conveyance and storage.
6. Pallet Warehouse: A library for storing empty pallets, where pallets can be stacked in an orderly manner for easy access.
7. Sensors and Vision Systems: Help robots identify and locate products, ensuring accurate handling and placement. Vision systems can also be used to inspect products for quality control.
Different End-of-Arm Tools of Robotic Palletizer
- Gripper: Commonly used for gripping bagged items, grippers can be customized with double grippers to grip double bags at once, adapting to various bag shapes and sizes.
- Vacuum Cup: Grips objects by means of a vacuum and is suitable for handling products with flat and smooth surfaces such as boxes and buckets.
- Clamp: The clamp securely grips products of different shapes and sizes, such as boxes, bags, or other canned goods.
- Custom EOATs: Custom designed EOATs offer tailored solutions that address specific applications or product types to fulfill unique handling requirements.
Applications
Robotic palletizers have many uses across industries:
- Food & Beverage: Stacked cartons, bags, bottles, and cans help streamline packaging operations while creating consistent stacking patterns.
- Pharmaceutical: Handling pill boxes and medical supplies ensures cleanliness and precision handling.
- Palletizing parts and finished products helps manufacturers improve efficiency while decreasing labor costs, and automating this process helps warehouses manage large volumes quickly and accurately.
- Consumer Goods: For household, electronic, and other consumer items that will be shipped via shipping carriers, packaging is vital in creating efficient stacking conditions and preparation.
Operational Considerations
- Space Requirements: Proper layout planning is essential to ensure that there is enough space for the robotic palletizer and its associated equipment.
- Integrate: For optimal operation with minimal interruption, seamlessly incorporate a robotic palletizer into an existing production line.
- Maintenance: For optimal performance and longevity, proper equipment maintenance must take place regularly. Create a maintenance schedule to keep it in tip-top shape.
- Training: Train operators and maintenance personnel to use the robotic palletizer safely and efficiently, and prevent accidents to ensure proper use.
- Product diversity: The robot should handle different types and sizes of products. Ensure that the palletizer can accommodate a variety of products to maintain versatility and efficiency.
- Throughput requirements: The robot must meet the required speed and efficiency. Evaluate production needs to ensure that the palletizer can handle the required throughput.
- Safety measures: Implement safety measures to protect workers and equipment. Develop and follow safety protocols and emergency procedures.
What are the limitations of palletizing robots?
Robot palletizing machines present many advantages; however, there can also be disadvantages:
- Initial Cost: Although initial investments may be higher, their long-term advantages often outweigh them.
- Flexibility: Irregular products may prove challenging to handle; custom solutions might need to be created specifically to manage them.
- Complex programming: Programming for different tasks can be complex and require expertise. A technician may be required for programming and maintenance.
- Space requirements: Sufficient space is required for installation and operation. Space restrictions may affect implementation in some facilities.
- Product Compatibility: Not all products are suitable for palletizing, especially very delicate or irregularly shaped products. Ensuring product compatibility is critical.
- Maintenance requirements: Regular maintenance is required.
Robotic palletizers are an indispensable automation tool. Their use has proven extremely beneficial in increasing work efficiency quickly while cutting labor costs over time, making operations safer, and optimizing logistics and manufacturing processes.
