Sheet metal storage is a chronic challenge in fabrication shops. Stacks of raw material occupy valuable floor space, require dangerous manual retrieval, and create delays when the required gauge or alloy is buried under heavier plates. Traditional cantilever racks or vertical storage towers still rely on fork lifts or overhead cranes to retrieve individual sheets—a slow and risky process. Herochu introduces a complete automated sheet metal storage system that integrates high‑density shelving with an intelligent three‑axis retrieval robot. This system not only stores sheets but also automatically feeds them to laser cutters, punches, or shears, creating a seamless just‑in‑time material flow.

Components of the Herochu Automated Sheet Metal Storage System

A fully functional automated sheet metal storage system consists of three subsystems working in coordination:

1. Storage structure – Customizable drawer‑type shelves, telescopic cantilever racks, or heavy‑duty pallet stands. Designed to hold sheet sizes from 0.5 m × 1 m to 2 m × 3 m, with load capacities per shelf up to 3000 kg.

2. Retrieval robot – Herochu’s three‑axis robot (100/200/300 kg payload) equipped with specialized grippers for metal sheets. The robot moves along the storage aisle or is mounted on a linear track.

3. Control software – Manages inventory, tracks sheet location by material type, thickness, and dimensions, and schedules retrieval based on production orders.

The system is manufactured by Ji’nan Constant Storage Machinery Manufacturing Co., LTD, a professional warehousing equipment manufacturer integrating R&D, production, sales, installation, and service. The brand name Herochu appears on every robot and control panel.

Why Automate Sheet Metal Storage?

Shops that rely on manual retrieval experience these pain points:

• Safety incidents: Sheets sliding from racks cause crushing injuries. Forklift collisions with storage racks are common.

• Damage to sheets: Dragging a sheet from the middle of a stack scratches both the retrieved sheet and the ones below.

• Lost time: Workers spend up to 30% of their shift searching for the correct sheet or moving other stacks to access the needed one.

• Low space utilization: Aisles must be wide enough for forklifts, reducing storage density by 40–50%.

Herochu’s automated sheet metal storage system solves all these issues. The robot retrieves sheets directly from any designated location, moves them smoothly without dragging, and delivers them to the processing machine—all under computer control.

Technical Specifications of the Retrieval Robot

The robot’s X/Y/Z working ranges can be selected from 50 mm to 300 mm cubes, depending on the required fine positioning. For storage applications, the robot typically uses a larger gross motion (provided by the arm span of 2700 mm) and then fine‑tunes the pick position using the working range.

Storage System Configurations

Drawer‑Type Sheet Metal Storage Shelves

Each drawer supports a single sheet or a small stack. The robot opens the drawer, picks the top sheet, and closes the drawer. This configuration offers the highest protection against scratching because sheets do not slide against each other. Drawer shelves are ideal for pre‑painted or stainless steel sheets. Herochu customizes drawer width, depth, and number of levels based on available ceiling height.

Telescopic Cantilever Storage Shelves

For high‑density storage of multiple sheet sizes, telescopic cantilever arms extend to present the sheet to the robot. These shelves are commonly used for aluminum plates and mild steel sheets. The cantilever arms can be spaced vertically as close as 150 mm, allowing storage of up to 20 sheets in a 3‑meter height.

Heavy‑Duty Sheet and Pipe Storage Shelves

Hybrid systems that store both sheets and round pipes. For sheet metal shops that also process tubes (e.g., for laser tube cutters), Herochu integrates pipe cradles alongside sheet shelves. The same robot can be equipped with a dual gripper (vacuum for sheets, V‑jaw for pipes) to handle both material types.

How the Automated System Works: Step‑by‑Step

1. Production order entry: The operator enters the required sheet material (e.g., 2 mm thick, 1500×3000 mm, hot‑rolled steel) into the control system.

2. Inventory lookup: The system identifies the storage location (e.g., drawer 7, level 3).

3. Robot navigation: The Herochu robot moves to that location. If the robot is mounted on a linear track, it travels along the aisle. If stationary, the base rotation axis (360°) aligns the arm with the storage bay.

4. Sheet retrieval: The robot extends its Z‑axis (linear), lowers the gripper, activates vacuum or closes the clamp, and lifts the sheet. The sprocket chain lift provides smooth, jerk‑free vertical motion.

5. Transfer: The robot rotates and extends to place the sheet onto a de‑stacking table, conveyor, or directly onto the laser cutter bed. The repositioning accuracy of ±0.05 mm ensures the sheet lands exactly where needed.

6. Inventory update: The system decrements the count for that material and can automatically reorder when stock falls below a threshold.

All cycles are completed in under 60 seconds for typical sheet sizes, including travel time.

Advantages Specific to Automated Sheet Metal Storage

Space Utilization Improvement

Manual storage requires wide forklift aisles—typically 3.5 to 4 meters. Herochu’s automated sheet metal storage system uses a robot that requires only 1.2 meters of aisle width (the robot’s base width). This reduction allows adding more storage rows or reducing building footprint. For a 1000 m² shop, converting to automated storage can free up 300–400 m² for additional production equipment.

Inventory Accuracy

Manual tracking with clipboards or basic spreadsheets leads to misplacements—“lost” sheets that are actually in the wrong rack. Herochu’s system uses barcode or RFID tags on each shelf and sheet. The robot can perform a full inventory scan in less than an hour, identifying every sheet’s location and condition.

Reduction in Material Damage

Sheets stored vertically in cantilever racks often develop edge dings from collision with fork tines. Sheets stored flat on pallets develop scratches from sliding. Herochu’s vacuum gripper picks sheets cleanly from the top, never touching the sheet’s face. The mechanical clamp (for thicker plates) grips only the edge within a designated “sacrificial” zone. As a result, usable sheet yield increases by 2–5%, directly improving profit margin.

Integration with ERP and MES

Herochu’s automated sheet metal storage system includes an API for connection to enterprise resource planning (ERP) and manufacturing execution system (MES) software. Production schedules automatically trigger sheet retrieval. The system can prioritize sheets by “first in, first out” (FIFO) to prevent material aging or oxidation.

Installation and Support

Ji’nan Constant Storage Machinery Manufacturing Co., LTD provides turnkey installation. The process begins with a site survey to measure floor flatness, ceiling height, and existing machine positions. Storage shelves are fabricated to custom dimensions.

For any metal fabricator seeking to move toward Industry 4.0, Herochu provides a proven, scalable, and quickly amortized solution.

The Unseen Workforce: Introducing the Herochu Automated Sheet Metal Storage System

Imagine a critical job order arrives. It requires a specific grade and thickness of steel plate. In a traditional shop, what follows is a familiar, time-consuming ritual: a operator climbs onto a forklift, navigates to a crowded storage area, and begins the physical labor of shifting heavy, precarious stacks of sheet metal. They’re searching, often by sight and memory, for the correct plate. Minutes turn into twenty. Dust is stirred, floors are scratched, and the risk of a costly slip or sheet damage looms with every movement. Finally, the right plate is found, extracted, and transported to the laser cutter. The machine, your most significant capital investment, has been idle all this time. This is the hidden tax of conventional storage—a tax on time, safety, and profitability.

The Herochu Automated Sheet Metal Storage System is not merely a piece of equipment; it is a fundamental re-engineering of your material handling workflow. It is the answer for forward-thinking manufacturers who recognize that true efficiency isn’t just about faster cutting speeds, but about eliminating the bottlenecks that exist between the cuts. This is the core of Industry 4.0: creating a seamless, intelligent, and autonomous flow of materials from storage to machine.

From Storage Clutter to Automated Command Center

The Herochu system transforms your raw material inventory from a static, chaotic pile into a dynamic, high-density vault. Think of it as a highly specialized, robotic librarian for your most valuable raw assets. Instead of relying on manual labor and guesswork, the system leverages Programmable Logic Controller (PLC) automation and an intuitive touch-screen interface to become the nerve center of your material flow.

The Core Promise: Centralized, Intelligent Control

• Centralized Storage: Every sheet, of every specification, is housed within a single, secure, and massively space-efficient structural frame. No more scattered piles across the workshop floor.

• Automatic Warehousing & Retrieval: This is the heart of the system. With a few commands on the touch screen, the machine itself locates, retrieves, and delivers the exact sheet you need. The operator’s role shifts from physical labor to supervisory command.

• Automatic Weight Detection: As sheets are stored, the system can log their weight, providing verifiable data for inventory management and ensuring no layer is overloaded beyond its engineered capacity.

• Classified Visual Management: The PLC software allows you to catalog your inventory digitally. You can input data like material type, thickness, grade, and job destination. The visual interface gives you a real-time, bird’s-eye view of your entire sheet metal stock, eliminating the chaos of “lost” inventory.

Engineering the Uncompromising: A Deep Dive into Herochu’s Automated Architecture

What separates a true industrial automation solution from a simple motorized rack? It’s the relentless focus on precision, durability, and seamless integration.

1. The Robotic Core: Precision Movement and Drive

The system’s ability to reliably handle tons of material with millimeter precision rests on its robust transmission and movement systems.

• Linear Guide Rail + Chain Movement: This combination is the workhorse of industrial automation. The linear guide rails ensure buttery-smooth, rigid, and precisely aligned horizontal and vertical movement, eliminating wobble or misalignment even under full 3-ton loads. The durable chain drive provides the powerful, positive engagement needed for consistent and reliable operation over millions of cycles. This is far superior to less robust systems like belt drives or simple rollers when dealing with such extreme weights.

• Optimized Performance Speeds: With a vertical lifting speed of 9 m/min and an inlet/outlet speed of 12 m/min, the system operates with a purposeful, efficient pace. It’s not rushed, because rushed movements lead to misalignments and dangerous pendulum effects on heavy sheets. It’s a speed designed for unwavering stability and precision, ensuring the sheet is presented perfectly for the next step in the process.

2. The Backbone: Structural Integrity and Customization

The framework of a Herochu system is a feat of structural engineering, designed not just to hold weight, but to do so dynamically and for decades.

• High-Strength Steel Construction: The main structure is fabricated from high-grade steel, ensuring it can withstand the constant stresses of moving loads and the dense weight of the stored inventory itself.

• Unmatched Customization: Your sheet metal inventory is unique. Your storage system must be, too. We offer complete customization on:

  • Number of Floors: Configure the height of your system to match your volume and ceiling height.

  • Number of Storage Units: Scale the system to your exact inventory needs.

  • Sheet Size: Standard models accommodate common sizes like 3015, 4020, and 6020mm, but we engineer solutions for any dimension you work with.

  • Load Capacity: Choose between a 3T or 5T load per layer to match the density of your materials.

3. The Intelligent Layer: Pallet and Support Systems

The point of contact with your valuable sheet metal is critical. Our drawer pallets are engineered for maximum support and minimal deflection.

• Engineered Pallets: With a pressure rating of 667 kg per square meter, the pallets are designed to support the sheet evenly across its entire surface, preventing the bowing or warping that can occur with inadequate support.

• Optional Support Configurations: We understand that different materials (e.g., delicate aluminum, thick steel, non-ferrous metals) may require different support structures. We offer optional pallet and support designs to ensure your specific materials are cradled perfectly, preserving their pristine surface quality.

The Tangible Transformation: Quantifying Your Return on Automation

Investing in a Herochu Automated System is a strategic decision that pays dividends across every facet of your operation.

1. Radical Space Liberation: The 23-Square-Meter Revolution

Space is your most finite resource. Traditional floor stacking is incredibly wasteful, requiring ample aisles for forklifts and room for personnel to maneuver. As our analysis shows, storing 8 different sizes of sheet metal in a traditional method can consume a vast area.

The Herochu 3015 model consolidates this entire inventory into a footprint of just 4.8m x 4.8m (approximately 23 square meters). This isn’t just incremental improvement; it’s a revolution. The square meters you reclaim can be used to install an additional laser cutter, a bending cell, or to create a more logical and safe production flow. It allows for capacity expansion without the prohibitive cost of a physical factory extension.

2. The Dawn of the “One-Person” Material Flow

Labor is your most valuable and costly resource. The Herochu system fundamentally changes the labor equation. What once required a skilled forklift operator’s full attention for extended periods now becomes a task that can be managed by a single person from a control panel. This “One-Person Operation” model doesn’t just reduce labor costs; it reallocates your human capital to higher-value tasks like machine programming, quality control, and process optimization. It is a critical step towards establishing a “black light factory” or automated production cell that can run with minimal human intervention.

3. Seamless Production Line Integration

An automated storage system in isolation is powerful. An automated storage system integrated with your production equipment is transformative. The Herochu system is designed for seamless connection with laser cutting machines, punching machines, and other automation equipment. It becomes the reliable feeder for your automated downstream processes, creating a continuous, uninterrupted production line. By integrating with ERP and MES systems, it provides real-time inventory data, enabling truly lean manufacturing and just-in-time material flow.

4. Unwavering Safety and Asset Protection

The safety benefits are profound. By automating the most physically dangerous aspect of sheet metal handling—the retrieval and transport of heavy, sharp plates—you virtually eliminate the risk of crushing injuries, forklift accidents, and sheet drops. Furthermore, storing sheets individually within a protected, enclosed structure completely prevents the scratches, dings, and edge damage common with traditional stacking, directly protecting your profit margins embedded in every raw sheet.
