When it comes to equipping your processing facility, choosing the right equipment can significantly impact your operations. Robotic palletizers present attractive advantages, but is upgrading to one really worth it? If you're torn between a conventional and robotic palletizer, you've arrived at the right place.
At TDI Packsys, we specialize in advanced automation and packaging solutions tailored for industrial facilities. Below, we’ll explore everything you need to know about the pros and cons of both conventional and robotic palletizing systems.
Understanding Conventional Palletizers
Conventional palletizers utilize conveyor belts to palletize one product at a time. This traditional method works best for facilities focused on a single SKU, offering limited flexibility. Despite its simplicity, a conventional palletizer can provide impressive speed and consistency when handling a single product type. However, there are several significant downsides to consider.
Typically, conventional palletizers come in two main varieties:
- Low-level palletizers: These operate using a floor-level conveyor belt to arrange products into aligned rows. The system then stacks these rows onto a pallet.
- High-level palletizers: Similar to low-level models, high-level palletizers also use conveyor belts but allow the pallet to be raised or lowered for faster throughput.
The Pros and Cons of Traditional Palletizers
Conventional palletizers excel in scenarios involving cube-shaped boxes. They can achieve decent speeds, averaging between 10 to 40 bags per minute or up to 200 compact boxes per minute. However, they come with notable drawbacks:
- Large footprint: Conventional palletizers require extensive conveyor systems, taking up valuable space in your facility.
- Maintenance demands: These systems often need regular upkeep, which can be time-consuming and costly.
- Moving parts prone to failure: Traditional palletizers have many components that can fail due to human error, posing safety risks.
- Limited versatility: Conventional systems are only suitable for a single product type.
- High energy consumption: These systems tend to consume more energy, driving up operational costs.
Exploring Robotic Palletizers
A robotic palletizer employs a robotic arm to pick up, orient, and distribute units onto pallets based on a pre-programmed pattern. Unlike conventional systems constrained by linear conveyors, robotic palletizers can handle multiple SKUs and a wide range of products, including entire sheets of boxes, pails, bags, bottles, bundles, drums, and more. The gripper can pick up multiple products at once, depending on the palletizing pattern, allowing for efficient and seamless throughput.
Popular Types of Robotic Palletizers
Robotic palletizers differ mainly in how their arms move and function. Some popular options include:
- Cartesian palletizers: Equipped with a single arm capable of moving in up to three directions.
- Selective Compliant Articulated Robot Arm (SCARA): Features a single arm that can move left, right, forward, or backward.
- Articulated palletizers: Utilize a swivel joint arm for maximum movement and flexibility.
The Benefits and Drawbacks of Robotic Palletizers
Robotic palletizers offer several advantages over their conventional counterparts:
- Greater flexibility and versatility: Robotic systems can palletize virtually any product type, including multiple items simultaneously.
- Enhanced speed and efficiency: Depending on your product and pattern complexity, robotic systems can achieve remarkable efficiency by packing entire sheets of units at once.
- Improved safety and reduced maintenance: Robotic palletizers are less prone to breakdowns, minimizing potential hazards and reducing maintenance needs.
- Increased precision: Robotic systems execute highly accurate patterns with minimal error margins.
- Lower energy and space usage: Modern robotic solutions consume less energy and occupy less space compared to conventional palletizers.
Despite these advantages, robotic palletizers come with some limitations. The sophisticated software requires more upfront training, which may not be feasible for smaller production environments.
Selecting the Right Palletizer for Your Facility
Deciding between a conventional and robotic palletizer involves weighing several critical factors:
- Speed and Throughput: Both systems can offer comparable speeds depending on the product type and specific model. Conventional palletizers are ideal for simple, compact boxes, while robotic systems excel across a broader range of products.
- Flexibility and Adaptability: If you only need to palletize one product type, a conventional system may suffice. For facilities handling multiple unit types, shapes, and sizes, a robotic palletizer is more adaptable.
- Product Handling Capabilities: Conventional palletizers handle cube-shaped boxes and bags effectively. Robotic palletizers can manage these as well as bottles, drums, entire pails of boxes, and more.
- Footprint and Space Requirements: Conventional palletizers typically require more floor space due to conveyor belt needs. Robotic systems are more compact, making them suitable for space-constrained facilities.
- Cost of Investment and Operation: Both systems involve similar upfront costs, but conventional systems usually incur higher maintenance expenses. They also consume more energy, leading to greater operational costs.
- Return on Investment (ROI): To maximize ROI, a robotic palletizer is likely the better choice. It helps reduce maintenance costs, downtime, and energy bills while improving efficiency.
Safety and Maintenance Considerations
When evaluating conventional versus robotic palletizers, safety is a crucial factor. A system malfunction could lead to workplace injuries, liability issues, and more.
Robotic palletizers generally offer safer operation due to their simpler design and fewer moving parts. Minimal upkeep reduces the risks associated with frequent human intervention, and most robotic systems feature protective cages to ensure safety.
Maintenance Requirements and Costs
Robotic palletizers are known for their reliability and uptime, requiring minimal maintenance. While conventional palletizers may not break down frequently, they do necessitate regular preventive maintenance, which can hinder productivity and profitability.
Operator Training and Skill Requirements
In the past, operating robotic palletizers was considered challenging, requiring extensive team training. However, advancements have made these systems more intuitive and user-friendly. Conventional palletizers usually demand little training since they are no more complex than other machinery in your facility. Robotic systems may require initial onboarding and software proficiency.
Integrating and Automating Each System
Beyond the core benefits and drawbacks, modern systems offer additional opportunities for enhancement. With a robotic palletizer, you can leverage its innovative integration features to automate your facility's operations further.
Integration Options With Other Systems
Robotic palletizers rely on software to function. Depending on the model you choose, you might integrate this software with other systems for seamless communication between stages of production. For instance, you could connect your palletizer with a slip sheet dispenser, pallet dispenser, or exit pallet conveyor to enable coordinated operation.
While conventional palletizers can integrate with other machines, they cannot match the level of automation achievable with robotic systems.
Automation Levels You Can Achieve
By integrating your packaging equipment, you can potentially achieve full automation. From product packaging to palletizing, robotic machinery can handle every step, minimizing human intervention while boosting efficiency. Since robotic palletizers can pick up units from various locations, they are versatile enough to support diverse applications across your facility.
The Role of AI and Machine Learning
Robotic palletizers utilize advanced software that enables enhanced data analysis. By incorporating AI and machine learning into your connected machinery, you may identify efficiency improvements or pinpoint issues causing downtime to optimize your facility's operations. These insights are unavailable with conventional systems.
