Palletizer Information

What is Palletizer

A palletizer is a machine which provides automatic means for stacking cases of goods or products onto a pallet. It is an automated system that stacks and organizes multiple products into a single load, making handling, storage, and shipping more efficient. It is commonly integrated into a larger packaging line, which may include additional functions such as weighing, counting, sorting, labeling, metal detection, and wrapping.

History of Palletizer

• Early Manual Stacking: Before the advent of automatic palletizing, manual hand stacking was used to organize products into pallet loads for storage and distribution. This method was labor-intensive and slow, requiring considerable effort for relatively low output.
• First Mechanical Palletizer: In 1948, the first mechanical palletizer was developed by Lamson Corp. It was a row-forming type, which arranged materials into rows. These rows were then transferred to another section where layers were stacked. This process was repeated until a complete stack of materials was formed, ready to be placed on a pallet.
• In-line Palletizer: In 1970, the need for faster logistics led to the introduction of the in-line palletizer. It utilizes a continuous motion flow divider that guides the goods into the desired area on the layer forming platform.
• Robotic Palletizers: In the early 1980s, robotic palletizers were introduced and have an end of arm tool (end effector) to grab the product from a conveyor or layer table and position it onto a pallet.

Purpose of Palletizer

• Improve Efficiency: Automatically stack products onto pallets, greatly reducing the time and labor cost compared with manual stacking, and improving the speed and efficiency of palletizing operations{insert_element_0_}.
• Enhance Stacking Quality: Ensure the accuracy and stability of product stacking, make the pallet stack more regular and stable, and reduce the risk of product damage and collapse during handling and transportation{insert_element_1_}.
• Optimize Space Utilization: Through reasonable stacking and arrangement, make full use of the space on the pallet, improve the space utilization rate of the warehouse and transportation vehicles, and reduce the storage and transportation costs.

Principle of Palletizer

• Mechanical Palletizers: Usually use conveyor belts to transport products to the palletizing area, and then through mechanical devices such as push plates, grippers, and lifting platforms, the products are stacked layer by layer on the pallet in a certain order{insert_element_2_}.
• Robotic Palletizers: The robotic arm is equipped with an end effector, which grabs the products from the conveyor or other feeding devices according to the预设的程序 and motion trajectory, and accurately places them on the pallet. The motion control system of the robotic arm and the visual recognition system of the end effector can ensure the accuracy and flexibility of palletizing{insert_element_3_}.

Features of Palletizer

• High Automation: It can complete the palletizing operation automatically without the need for manual intervention, reducing labor costs and improving production efficiency{insert_element_4_}.
• High Precision: With precise control systems and sensors, it can ensure the accuracy of product stacking, and the stacking position and height error are small{insert_element_5_}.
• Flexible Adaptability: It can be adjusted and configured according to different product sizes, shapes, weights and palletizing requirements to adapt to a variety of production lines and palletizing tasks{insert_element_6_}.
• High Safety: The equipment is equipped with safety protection devices such as emergency stop buttons, safety guards and photoelectric sensors to ensure the safety of operators and equipment during operation{insert_element_7_}.

Types of Palletizer

• Mechanical Palletizers: It has a simple structure, low cost and high reliability, and is suitable for palletizing single and regular products in small and medium-sized enterprises. It includes龙门式码垛机, 立柱式码垛机 and 机械臂式码垛机等{insert_element_8_}.
• Robotic Palletizers: It has high flexibility and accuracy, can handle complex palletizing tasks and random product placement, and is widely used in large-scale production lines and automated warehouses. It can be divided intoarticulated robot palletizers, SCARA robot palletizers and Delta robot palletizers according to the type of robotic arm{insert_element_9_}.
• In-line Palletizers: It is suitable for high-speed production lines with continuous motion, which can continuously stack products on pallets at a high speed and improve the production efficiency of the production line.
