Types of palletizing robots

With the flexible and strong joints of industrial robot arms and other machinery, palletizing robots come in various types to meet different needs. The most common way to classify them is by their structure.

• Column robots have three or more vertical and horizontal joints resembling human arms. Their strength lies in their ability to cover wide areas and reach high shelves. Column robots are good for handling medium to large items. Like other palletizing robots, they can perform various functions by replacing their end effectors.

• Cylindrical robots have a column-like polar coordinate system. They offer a low-cost alternative for palletizing tasks that require less precision but an adequate reach. Their simple design makes them easy to maintain in harsh environments, though their speed and accuracy may not match other types of robots.

• Delta robots are a good option for quickly packing items into boxes. Their design gives them the capability to move very fast. They have excellent acceleration and deceleration performance, enabling them to work without stopping for long periods between tasks. Delta robots also take up little space, making them easy to fit into tight places.

• SCARA robots, known as Selective Compliance Assembly Robot Arms, have an arm with rotary joints. SCARA palletizing robots are suitable for tasks that require picking and placing actions. For example, they can stack boxes on pallets and toppling them with excellent precision at high speed. Their simple design enables them to be affordable options for many businesses.

• Cobots, or collaborative robots, are designed to work alongside humans. They offer a flexible palletizing solution with safe motion systems and user-friendly interfaces. Cobots can handle multiple tasks, adapt to changing production lines, and reduce downtime. Their collaborative nature allows easy integration into existing workflows.

Specifications and maintenance of palletizing robots

Industrial robots are usually measured based on their reach, payload capacity, accuracy, speed, number of axes, and other specifications. Here are the common specifications for the robots:

• Reach: It refers to the maximum distance the robotic arm can extend from its base. Reach is typically measured in meters or inches. Robots built for tall and wide packages will have longer reaches.
• Payload capacity: This is the maximum weight the robot can handle safely. It’s typically measured in kilograms or pounds. The weight of the box that the robot is expected to handle will determine the payload capacity of the robot.
• Precision and accuracy: These refer to the robot’s ability to stack items in the exact desired location consistently. They are usually measured in millimeters or centimeters. Precision and accuracy are crucial especially when the concern is around stability and balancing of stacked items. The higher the accuracy of a robot, the more costly it is.
• Speed: It indicates how quickly the robot can move and perform tasks such as stacking or picking. Speed is often measured in cycles per hour. Speed requirements will vary depending on the production linespace and desired output.
• Number of axes: This refers to the robot's joints and axes, which determine its range of motion and flexibility. Most palletizing robots have 4 to 6 axes. The more the axes, the greater the flexibility and accuracy of the robot.

Robotic arms require periodic maintenance so that they continue to function optimally over a long period of time. Here are a few general maintenance tips that apply to most robotic arms:

• Lubrication: Regularly lubricate joints and gears in the robotic arm. Lubrication reduces wear and tear and it also minimizes friction and operating noise.
• Inspection and cleaning: Carry out regular cleaning and inspection of the robotic arm. This will help to identify any damage, debris, or loose parts that may require immediate attention. As a guide, manufacturers recommend cleaning the arm after every hour of operations.
• Calibration: Regularly check and calibrate the robot’s sensors and joints to maintain high levels of precision and accuracy. Ir frequent calibration can lead to drift phenomenon over time, where the robot gradually loses its precision.
• Software updates: Update the robot’s software regularly. This helps to improve performance, add new features and enhance security.
• Operating conditions: Monitor the environmental conditions the robotic arm operates in. Maintain appropriate temperature and humidity within recommended ranges. Also, protect the arm from harsh environmental elements such as dust, moisture, chemicals, and extreme temperatures.

Scenarios of palletizing robots

Palletizing robots are widely used in various industries, providing multiple options for handling and packaging products. Here are some typical application scenarios for palletizing robots.

Robot palletizers are commonly used in food and beverage production lines to package bottles, cans, boxes, and other containers. They can efficiently stack these items onto pallets according to predefined patterns, optimizing space utilization and ensuring securely packed pallets.

In the e-commerce and logistics industry, palletizing robots play a crucial role. They are used to handle and stack parcels, boxes, and other goods onto pallets for efficient sorting, packing, and shipping. Their high-speed operation helps enhance warehouse productivity and streamline logistics processes.

The grocery industry utilizes robot palletizers for packaging operations. These robots are employed to stack grocery items, such as cartons, boxes, and bags, onto pallets for efficient distribution to stores. With their flexibility and adaptability, they can handle various grocery products and ensure timely and accurate palletizing.

Manufacturing industries, including electronics, automotive, consumer goods, and more, extensively use palletizing robots. They are used to stack finished products, components, cartons, and other items onto pallets for consolidation and distribution. The robots' precision and speed contribute to improving production efficiency and streamlining workflow.

Palletizing robots are utilized in the pharmaceutical and cosmetics industries for packaging operations. They are employed to stack pharmaceutical products, cosmetics containers, and other delicate items onto pallets with accuracy and care. Robot palletizers ensure proper arrangement, reduce the risk of damage, and enhance productivity in these regulated industries.

Robotic palletizers find applications in the chemical industry for handling and stacking chemical products, containers, drums, and other hazardous materials. They provide safe and efficient palletizing solutions while maintaining proper handling procedures for chemicals.

Palletizing robots are commonly used in the household product industry for packaging operations. They are employed to stack household items, such as cleaning products, personal care products, and other consumer goods, onto pallets for distribution to retail stores or warehouses.

How to Choose Palletizing Robots

Various factors need to be considered when selecting the right palletizing robot. They include the size, weight, and shape of the products to be palletized, the amount of product delivered per time, the desired level of automation, the budgetary constraints, and the floor space available at the facility.

Robots come in different load and item handling capacities. Consider the weight and dimensions of the items to be palletized and ensure that the robot chosen can handle them comfortably. Smaller robots that handle lighter loads are more common, while larger robots or those with additional automation capabilities are available but at a higher price.

Whether a robotic palletizer or one with an automated function is chosen will depend on how manual or automated the workflow is. Manual palletizing can be tedious, repetitive, and exhausting, leading to low productivity and high levels of staff turnover. Automated robots cost less to run in the long term, but they are more expensive initially.

Consider how much needs to be palletized per hour. High-throughput facilities that handle large volumes of products would require a robot with a higher speed and capacity compared to small warehouses or facilities that handle smaller volumes. The amount of floor space available will also be a consideration, as robots take up more space than manual palletizing.

Due diligence needs to be done, and multiple suppliers should be contacted and compared before making a final decision, as the choice of robot will have a long-term impact on efficiency, costs, and the facility’s overall functioning.
