Automatic Sheet Metal Storage & Retrieval System (AS/RS)

The manufacturing landscape has undergone a fundamental transformation over the past decade. Where once sheet metal fabrication relied heavily on manual labor, forklift traffic, and sprawling floor layouts, today’s competitive environment demands precision, speed, and intelligent material flow. The Automatic Sheet Metal Storage & Retrieval System (AS/RS) represents the culmination of this evolution—a fully integrated solution that bridges the critical gap between raw material inventory and production equipment.

Herochu has engineered its AS/RS platform to address the most persistent challenges facing metal fabricators: floor space constraints, manual retrieval bottlenecks, inventory inaccuracies, and machine idle time. By combining high-density vertical storage with robotic handling and intelligent software, this system transforms the traditional warehouse into a synchronized, high-velocity material supply chain.

System Architecture and Core Components

The Herochu Automatic Sheet Metal Storage & Retrieval System is built upon a robust architectural foundation. At its core lies a high-density drive-in pallet rack storage design, optimized for storing similar-sized sheet metal pallets in depth. This structure is reinforced with advanced steel automatic loading and unloading warehouse racks, finished with durable powder coating to withstand the rigors of industrial environments.

The retrieval mechanism operates on a combination of linear guide rails and chain drive transmission, ensuring smooth, reliable, and precisely positioned movement. This configuration enables the system to handle up to 1,800 kilograms of material per retrieval cycle with ease. The entire architecture functions as a fully automatic three-dimensional storage unit, featuring vertical lifts, horizontal shuttles, and robotic end-effectors that handle sheets with millimeter accuracy.

Robotic Handling and Unmanned Operation

One of the defining characteristics of the Herochu AS/RS is its autonomous operation capability. The system employs high-precision robotic arms and AGV transfer systems that retrieve required sheets and deliver them directly to the laser loader—entirely without manual handling. This robotic orchestration eliminates the dependency on forklifts and manual labor, cutting labor costs by up to 70% while simultaneously increasing daily cutting throughput by 40% to 60%.

The system is designed for true “lights-out” manufacturing. Once the production schedule is loaded, the AS/RS operates continuously through the night and across weekends, transforming cutting equipment into continuous processing assets. This unmanned capability is particularly valuable for facilities running 24/7 operations, where every minute of machine downtime translates directly into lost revenue.

Intelligent Warehouse Management System

The Herochu AS/RS is equipped with a sophisticated Warehouse Management System (WMS) that provides real-time inventory visibility and control. The WMS supports instant inventory queries, batch traceability, and expiration warnings, ensuring that material managers always have accurate information at their fingertips.

The scan-in and automatic positioning functionality achieves 100% accuracy, eliminating the errors, omissions, and inventory overstock that plague manual systems. Every sheet that enters the system is bar-coded, weighed, and stored by alloy, thickness, and job priority. This level of precision ensures that the right material is always available for the right job at the right time.

ERP Integration and Data Intelligence

Perhaps the most transformative aspect of the Herochu AS/RS is its seamless integration with enterprise resource planning (ERP) systems. This connection enables the integration of production, warehousing, and logistics data into a unified information platform. Production managers can view real-time inventory levels, track material consumption, and make intelligent decisions based on accurate, up-to-date information.

The ERP integration also supports predictive material staging based on production schedules. When a new order enters the system, the AS/RS can automatically prepare the required sheets for the cutting operation, reducing setup times and improving overall equipment effectiveness. This data-driven approach transforms the storage system from a passive warehouse into an active participant in the production planning process.

Technical Specifications and Customization

The Herochu AS/RS platform offers extensive customization options to match specific operational requirements. Standard configurations include up to 15 storage layers and multiple storage towers, with maximum storage dimensions reaching 6,000 by 2,500 millimeters. Per-layer load capacity can be specified up to 5,000 kilograms, accommodating everything from thin gauge aluminum to heavy steel plate.

The system operates with storage in/out exchange speeds of 5 to 15 meters per minute and lift speeds in the same range. Equipment lifting power ranges from 5.5 to 11 kilowatts, with inlet and outlet motor power between 1.5 and 2.2 kilowatts. The system supports both 220V and 380V input voltages at 50Hz or 60Hz power supply requirements.

For demanding industrial environments, the Herochu AS/RS features IP67 sensor protection rating and communicates via Siemens S7 protocol. Repetitive positioning accuracy is maintained at ±2 millimeters, ensuring consistent, reliable sheet placement.

Operational Benefits

The implementation of the Herochu Automatic Sheet Metal Storage & Retrieval System delivers measurable operational improvements across the entire fabrication workflow. Floor space utilization increases by up to 200% compared to traditional flat shelving, reclaiming valuable production area. Material change-over times are reduced to under 90 seconds, dramatically improving machine utilization.

Inventory accuracy reaches 99.8%, eliminating the costly errors associated with manual counting and record-keeping. Forklift traffic is reduced by up to 70%, significantly improving shop floor safety and reducing the risk of sheet damage caused by forklift tines. The system is fully compatible with forklifts, overhead cranes, and other lifting equipment, ensuring seamless integration with existing material handling infrastructure.

Conclusion

The Automatic Sheet Metal Storage & Retrieval System from Herochu represents a fundamental advancement in material handling technology. By integrating high-density vertical storage, robotic retrieval, intelligent inventory management, and seamless ERP connectivity, this AS/RS solution enables fabricators to achieve new levels of productivity, accuracy, and operational efficiency. For manufacturers seeking to eliminate bottlenecks, reduce labor costs, and unlock the full potential of their production equipment, the Herochu AS/RS provides a comprehensive, future-ready solution.
