Laser Cutting Machine Loading and Heavy Duty Pallet Rack Storage

Loading a laser cutting machine efficiently requires more than just a forklift and a stack of pallets. The loading process directly affects machine utilization, operator fatigue, and material surface quality. Similarly, heavy duty pallet rack storage for laser cutting machine loading must accommodate not only raw sheets but also finished parts, skeletons (remaining grid structures after cutting), and scrap. Herochu has developed a comprehensive system for laser cutting machine loading and heavy duty pallet rack storage that handles up to 1000kg per lift with the Servo Swing Arm Manipulator and stores up to 6 tons per layer in the HC-B drawer-type rack. This article details how Herochu solves the loading and storage challenges specific to high-volume laser cutting operations.

The Demands of Laser Cutting Machine Loading

Laser cutting machines, whether fiber or CO2, have become faster and more automated. A modern 6kW fiber laser can cut 1mm stainless steel at speeds exceeding 30 meters per minute. At that pace, the cutting table empties every few minutes. If the loading system cannot deliver the next sheet within 30 seconds, the laser sits idle. Traditional laser cutting machine loading methods – overhead crane with vacuum lifter or manual forklift – typically take 60-90 seconds per sheet, leading to significant downtime over a shift. Herochu’s Servo Swing Arm Handling Manipulator reduces loading cycle time to 20-30 seconds, directly increasing laser utilization by 15-25%.

But fast loading is meaningless if the storage system cannot stage sheets close to the machine. That is where Herochu’s heavy duty pallet rack storage design comes in. Unlike standard pallet racks designed for boxed goods, Herochu’s HC-B series racks are specifically engineered for flat sheet metal, with each “pallet” being a full-extension drawer capable of holding 3 to 6 tons.

Herochu Servo Swing Arm Handling Manipulator for Laser Cutting Machine Loading

The manipulator is available in three capacity classes: 300kg, 500kg, and 1000kg, corresponding to models HC-R3015-500 (300kg max), HC-R3015-750 (500kg), and HC-R3015-1000 (1000kg). All models support maximum feeding formats of 3000x1500mm or 4000x2000mm, with minimum feeding formats as small as 1250x1000mm. The manipulator uses electric servo power – no compressed air required – making it suitable for shops without high-CFM air compressors.

Key features for laser cutting machine loading:

• Variable speed control: Move heavy plates slowly during alignment, then faster during transport.

• Suction cup array: 15 to 118 cups; diameters 150mm, 200mm, or 250mm. For loading thin sheets (1-8mm), the high cup count prevents localized dimpling.

• Emergency stop and auto-braking: If an operator releases the handle or if power fluctuates, the brake engages and holds the load. No drifting or dropping.

• Modular assembly: The manipulator can be disassembled into modules that fit through a standard doorway, then reassembled on-site.

The manipulator mounts on a swing arm base that allows 180-degree rotation, covering the area between the storage rack and the laser cutting machine’s loading side. For shops with multiple laser cutting machines, Herochu offers a track-mounted version that serves several machines.

Heavy Duty Pallet Rack Storage – Redefining “Pallet” for Sheet Metal

Standard heavy duty pallet racks use wooden or metal pallets that sit on beams. This design works for discrete items but fails for sheet metal because sheets cannot be easily pulled from the middle of a pallet stack. Herochu’s HC-B drawer-type rack redefines heavy duty pallet rack storage for laser cutting applications by making each “pallet position” a fully extendable drawer. The rack is built from Q235B/Q355 steel, with bolt-together construction and laser-cut precision holes.

Model HC-B6020-66 is the flagship for heavy duty storage: it handles 6000x2000mm sheets (the largest standard size in many industries) and supports 6 tons per layer. With 6 layers (5 storage + 1 top), total rack capacity reaches 30 tons. External dimensions are 6505mm long x 2280mm deep x 2500mm high. The bottom layer has 355mm ground clearance, and each drawer moves on integrated pull-out bearings.

For shops that do not need the full 6-ton capacity, Herochu offers HC-B3015-63 (3 tons per layer) and HC-B4015-63 (5 tons per layer). All racks include a depth pad height that ensures the sheet sits slightly above the drawer surface, reducing friction during loading and unloading.

Loading Workflow with Herochu’s Integrated System

A typical laser cutting machine loading and heavy duty pallet rack storage workflow using Herochu equipment:

1. Preparation: The operator receives a cutting job order that specifies material type, thickness, and sheet size.

2. Drawer selection: The operator pulls out the correct drawer from the HC-B rack. The drawer extends fully, exposing the entire top sheet.

3. Manipulator pickup: The Servo Swing Arm Manipulator moves over the extended drawer. The operator lowers the suction cups onto the sheet, activates the vacuum, and the auto-brake holds the sheet.

4. Loading: The manipulator swings to the laser cutting machine’s loading position. The operator positions the sheet precisely over the cutting bed or exchange table, releases the vacuum, and retracts the cups.

5. Unloading finished parts: For cut parts, Herochu can integrate a second manipulator or a conveyor system. Alternatively, small parts are manually removed and placed into smaller pallet racks or bins.

The entire cycle from drawer pull to sheet loaded takes under 45 seconds with an experienced operator. For automated lines, Herochu’s engineering team can integrate a PLC-controlled sequence that triggers drawer extension and manipulator movement without manual intervention.

Frequently Asked Questions for Heavy Duty Systems

Q: How do I proceed with procurement of a Herochu loading and storage system?
A: Contact Herochu’s technical personnel through the background portal. Provide your laser cutting machine parameters (table size, loading height, cycle time), the materials you cut (type, thickness, sheet size), and your storage volume (number of sheets per material). Herochu will provide a suitable technical solution and quotation. Alternatively, leave your WhatsApp, WeChat, or email for a sales team callback.

Q: Can the heavy duty rack store cut skeletons (remaining grid structures)?
A: Yes. Herochu recommends dedicating one drawer for skeleton storage. Because skeletons are irregular and may have sharp edges, Herochu can supply a protective grid liner to prevent damage to the drawer surface.

Q: Do I need a loading robotic arm or an integrated loading/unloading system?
A: That depends on your laser cutting machine table design and your production volume. Herochu needs to know the specific loading method you prefer: board rack (direct loading from the storage drawer), exchange platform (shuttle table), or material warehouse (fully automated storage and retrieval). Provide these details, and Herochu will design accordingly. Leave your contact information for a detailed consultation.
