What Automated Warehouse Systems Are There?

In a nutshell: The automation of warehouse systems is a key factor for efficient and cost-effective logistics processes. However, not every system is the right fit for every company. This article provides an overview of the most important automated warehouse systems, highlights their advantages, and sheds light on potential challenges. 

Cube Storage Solutions: Maximum Space Utilization 

Cube Storage systems are revolutionizing warehousing by efficiently utilizing available space in a cubic format. Bins are stacked on top of one another and retrieved by robots, enabling an extremely high storage density. 

Advantages:  

• Maximum space utilization 
• High picking speed
• Small footprint 

However: High capital investment and dependency on automated robotic systems.  

Small Parts Shuttle: Speed for the Small Parts Sector 

Shuttle systems are ideal for dynamic storage and rapid access to small parts. The driverless shuttles move on rails and transport bins to picking stations. 

Advantages:  

• High speed 
• Modularity and scalability 

However: Complex control systems and high maintenance requirements.  

Automated Small Parts Warehouses (AS/RS): High Precision for Small Goods 

AS/RS systems use stacker cranes or shuttles to store small parts in specially designed racking. They are ideal for a large number of items with small dimensions. 

Advantages: 

• High storage capacity 
• Efficient use of space 
• Precise order picking 

However: Increased maintenance requirements and complex integration into existing systems.  

Shelf to Person: Automating the Picking Process 

This system brings entire shelving units or compartments directly to the employee at a pick station, eliminating walking distances and increasing efficiency. 

Advantages:  

• Reduced walking distances 
• Improved ergonomics  
• Increased productivity 

However: Dependence on stable software control and limited flexibility for spontaneous changes.  

Autonomous Case-Handling Robots (ACR): Flexibility Through AI-Driven Robots 

ACR systems rely on autonomous robots that transport crates or bins and support picking processes. The AI-driven control enables dynamic adaptation of processes. 

Advantages: 

• High flexibility 
• Easy scalability 
• Intelligent control 

However: High initial investment and potential vulnerability to IT disruptions.  

Tray Storage Systems: Efficient Storage for Heavy and Sensitive Goods 

Tray storage systems use tray-based solutions on which goods are stored securely and automatically conveyed to picking stations. 

Advantages:  

• Ideal for heavy or sensitive goods 
• High efficiency through vertical utilization 

However: Limited adaptability to highly fluctuating storage requirements.  

Carousel Systems / Rotary Storage: Rotating Efficiency for Fast Access 

These systems use rotating shelves or storage compartments that bring items directly to the picking station. They are ideal for items with a high access frequency. 

Advantages:  

• Fast availability 
• Small footprint 
• High ergonomics 

However: Limited flexibility with irregular inventory levels and high maintenance requirements.  

Vertical Lift Modules (VLM): Space-Saving Storage Solution for High Efficiency 

VLM systems use vertical lifts that automatically deliver bins or trays to the picking station. They offer an ideal solution for limited storage space. 

Advantages:  

• Maximum space utilization 
• High security 
• Ergonomic operation 

However: High initial investment costs and limited adaptability for large goods.  

Conclusion: The Right Automated Warehouse System for Greater Efficiency 

Automated warehouse systems offer a wide range of opportunities to optimize warehouse logistics. Choosing the right system depends on individual requirements, budget, and warehouse structure. Companies should conduct a thorough needs analysis in order to benefit from the advantages in the long term. Find out in this article how to choose the right warehouse system.
