Automated Laser Cutting Loading System

The fiber laser on a modern fabrication floor is rarely the constraint. The bottleneck sits beside it: the operator threading a forklift through narrow aisles, the manual alignment of a 3,000 × 1,500 mm plate, the fifteen-minute gap between the last cut and the next arc-on. Herochu built the Automated Laser Cutting Loading System to close that gap permanently. This is not a loader bolted onto a machine. It is an integrated material flow architecture—storage tower, gantry manipulator, and discharge cart—engineered to keep the beam cutting while everything else happens in parallel.

Why Manual Loading Caps Laser Capacity

A 6 kW fiber laser can cut 3 mm mild steel at extraordinary speed, but only while the sheet is on the bed. Every manual exchange inserts non-productive minutes: fetching the next plate, checking for double sheets, aligning against stops, and clearing the skeleton afterward. Across two shifts, those minutes compound into hours of lost beam-on time. Herochu’s system addresses the root cause rather than the symptom. The storage tower holds raw plate in eight to ten configurable layers, with load capacities from 3,000 to 5,000 kg per layer depending on model. When the cutting program signals a pending sheet requirement, the gantry retrieves the correct plate before the current cycle ends, staging it above the bed so the exchange begins the moment the cut completes.

The Gantry That Understands Material Behavior

Not all sheet metal behaves identically under vacuum. Oily carbon steel clings. Film-covered aluminum releases unpredictably. Thin stainless flexes in ways that defeat single-zone suction. Herochu’s loading arm incorporates independent vacuum zone control, allowing inactive zones to seal off when nested parts or cutouts pass beneath the cups. A mechanical micro-flexing action at the Z-axis breaks the oil seal between stacked plates, followed by a compressed air injection at 0.6–0.7 MPa to separate stubborn sheets. Thickness verification confirms single-sheet isolation before the traverse begins. This sequence is not a luxury; it is the difference between reliable unattended operation and a crashed cutting head.

Technical Parameters That Define the Envelope

The HC-A series spans four standard configurations:

The loading arm traverses horizontally at 10–30 m/min and lifts at 5–10 m/min, with fork adjustment speeds of 5–20 m/min. Clear space is customizable to 350 mm, accommodating the plate support tooling that varies between shops. These are not abstract numbers. They determine whether the system keeps pace with a 4 kW laser on thin gauge or a 12 kW unit on 20 mm plate.

Layout as a Design Variable, Not an Afterthought

Herochu does not ship a fixed footprint. The storage tower, rail length, and discharge cart position are configured against the customer’s actual floor plan—ceiling height, aisle width, crane paths, and existing laser table orientation. A single gantry can serve two storage towers and two separate cutting beds, effectively doubling output per square meter of shop floor. For fabricators who have already maximized floor space, this multi-machine architecture is often the only path to capacity growth without a building expansion.

Conclusion

The Automated Laser Cutting Loading System from Herochu is an investment in beam-on time. By removing manual handling from the critical path, it converts a high-value laser into a continuously productive asset rather than a machine that waits. For shops running two shifts or contemplating lights-out operation, the system provides the material flow foundation that makes those ambitions operational rather than aspirational.
