Introduction
Robotic palletizers are revolutionising the way businesses handle end-of-line packaging. These automated systems efficiently stack boxes, bags, and other products onto pallets, significantly improving productivity and safety. In our previous article, we discussed the various palletizing robot applications that can improve your production operation.
While the benefits are clear, understanding the cost of a robotic palletizer is crucial before making this investment. This article explores the various factors that influence the price tag and provides tips for optimising your purchase.
Understanding the Value Proposition
Palletizing robot arms offer a multitude of advantages over manual palletizing. They can operate continuously, increasing output and throughput. This translates to reduced labour costs and frees up employees for other tasks. Additionally, robots eliminate the risk of injuries associated with manual lifting and repetitive motions.
However, the initial cost of a robotic palletizer can be substantial. Therefore, it’s essential to be fully informed about the price breakdown before taking the plunge.
Factors Affecting Robotic Palletizer Cost
Several factors contribute to the overall cost of a robotic palletizer system. Here’s a breakdown of the key considerations:
Robot Type: Robots are categorised by the number of axes they have for movement. A 4-axis robot offers basic up-down, left-right, and forward-backward movement. It’s the most economical option, while also offering some of the best and versatile applications for palletizing.
5-axis and 6-axis robots offer additional wrist articulation for greater flexibility and can handle intricate palletizing tasks. However, 5-axis and 6-axis cost much more than a 4-axis robot, and these specific types of robots require additional maintenance that may hinder your operation’s overall flow.
Payload Capacity and Reach: The robot’s payload capacity determines the weight it can handle. Likewise, the reach determines how far it can extend its arm to pick and place products. These specifications directly impact the robot model selected and ultimately, the cost. For example, a robot palletizer handling heavy palletized loads will require a higher payload capacity, increasing the price compared to a system handling lighter loads.
End-of-Arm Tooling (EOAT): This is the attachment on the robot’s arm that interacts with your products. The type of Gripper depends on the product characteristics. Vacuum grippers are ideal for flat, sealed packages. Mechanical grippers work well for rigid boxes. Specialised Grippers like carton erectors, or slip sheet dispensers, add functionality but also increase the cost. Grippers play a very crucial role in the success of palletizing applications.
Not many robot manufacturers produce their own Grippers due to its complexity and also require a deep understanding of product characteristics to be handled across different industries. Okura is a unique brand that has specialised in robot palletizing application with their own robot, many types of grippers, thousands of palletizing patterns for easy setting up.
System Integration: Integrating the robot with your existing workflow might involve additional expenses. This could include conveyor systems for product infeed and outfeed, safety fencing to ensure a secure work environment, and integration with your production control system.
Additional Features: Optional features like vision systems can be integrated for product recognition and optimising palletizing patterns. These features enhance efficiency but come at an added cost.
Manufacturer and Brand: Established robotic brands with proven track records typically command a premium price. Lesser-known manufacturers might offer lower upfront costs, but it’s crucial to evaluate the quality, warranty terms, and long-term support they provide.
Safety Features: Robotic palletizers incorporate safety features like fences, light curtains, and safety-rated components. Enhanced safety features ensure operator safety but might increase the overall cost.
Warranty and Ongoing Support: The warranty length and coverage offered by the manufacturer can influence total cost. Similarly, consider the cost of ongoing maintenance and support services provided by the integrator or robot manufacturer.
Environmental Factors: Harsh environments like those with extreme temperatures, dust, or moisture require specialised robots with additional features to ensure proper operation, leading to a higher cost.
Optimising Costs for Your Needs
When considering robotic palletizers, it’s vital to identify your specific needs to avoid overspending on unnecessary features. Carefully analyse your product characteristics, production volume, and desired palletizing patterns. This will help you select a robot with the right capabilities at a cost that aligns with your budget.
Exploring options for used robots with proper inspection and warranty can be a viable cost-saving alternative. Financing options are also available through banks or equipment leasing companies.
The long-term cost analysis shouldn’t solely focus on the upfront cost of the robot palletizer. Consider the return on investment (ROI) achieved through increased productivity, reduced labour costs, and minimised workplace injuries.
Conclusion
The cost of a robotic palletizer can vary significantly depending on the factors discussed above. Understanding these factors will empower you to make informed decisions when selecting a system that optimises your palletizing operation. Remember, robotic palletizing offers substantial benefits in terms of efficiency, safety, and cost savings in the long run.
