Coil-Fed CNC Laser Cutting Line

Process flow
An overhead crane places the coil on a loading cart. A hydraulic lift aligns it with the decoiler mandrel, which enters and expands inside the coil. The sheet passes through pinch rolls and a precision leveler before being transported to the cutting area. Marking, labeling and automatic stacking are optional reference functions.

Loading and decoiling
The loading cart operates outside the mandrel, lifts the coil into position, then lowers and returns after the mandrel has expanded. The decoiler uses tension-controlled unwinding. Load, coil dimensions, expansion range and construction details are maintained in the separate decoiler specification group.

Threading system
The welded frame, guide tongue and straightening head support and guide the leading edge into the pinch rolls. Hydraulic cylinders raise the hardened guide head and extend the transition plate. Support-plate, guide-plate and cylinder details are listed separately.

Leveling and drive
The source describes a six-high, 24-roll leveler for reference materials including stainless steel, clad sheet, galvanized sheet, nonferrous sheet and aluminum. Features include digital position indication, motorized adjustment, stop control and forward/reverse switching. Thickness and strength limits need confirmation. The main drive uses a motor, reducer, gear distribution box, couplings and universal shafts to drive the upper and lower work rolls. A DC motor and digital DC controller are described. Needle bearings, intermediate rolls, support rolls and wedge-adjusted supports are used to support the work rolls and limit sheet marking.

Laser cutting
The welded bed is annealed, vibration-aged and finish-machined. Rack-and-pinion and guideway drives use Yaskawa servos, with automatic lubrication on moving components. A MAX 6000 W laser source is listed for reference processing of aluminum, carbon steel, stainless steel and galvanized sheet. Worktable size, axis travel, positioning and speeds are maintained in a separate cutting-unit table.

Laser source and cutting head
The source describes customizable fiber length, QBH/QD connections and a broad modulation range. The configuration table lists “Precitech Procutter2.0,” while the feature text lists “LightCutter Zoom 2.0” and a power range up to 6 kW. These descriptions must not be treated as one confirmed configuration.

Sorting and unloading
The reference gripper combines vacuum cups and electromagnets to separate finished parts and scrap, with adjustable spacing. A six-axis ESTUN ER220-2650 robot is illustrated with 2650 mm reach, ±0.02 mm repeatability and 220 kg maximum payload; confirm these against the selected robot and end effector. A gantry unloading arrangement is another reference option.

Marking and power options
Listed marking powers are 20/30/50 W, with a field from 100 × 100 to 300 × 300 mm and maximum marking speed of 8000 mm/s. Listed interface languages are Chinese, English, French, German, Spanish and Russian. The industrial UPS description includes input/output isolation, digital DSP control and a modular layout; capacity and configuration are unspecified.

Configuration records
The component tables preserve the source brands, origins and quantities for controls, nesting software, servos, guideways, racks, pneumatics, optics, cooling, electrical equipment and handling platforms. Unverified market-share and maintenance-free claims are not presented as performance commitments.
