Exporting finished sofas presents unique challenges: bulky dimensions, high freight fees, and risk of damage in transit. The NG-43RL Automatic Sofa Compression & Rolling Machine by NAIGU solves these problems with a seamlessly integrated workflow. Below is a detailed, step-by-step guide to how the NG-43RL transforms standard sofas into tightly rolled packs optimized for global shipping.

1. Sofa Loading & Positioning

Upon arrival at the NG-43RL inlet conveyor:

Operator Alignment: The sofa is placed upright on the conveyor and manually guided into centering guides.
Automatic Sensors: Position sensors detect the sofa’s width and height, triggering the machine’s sequence.

Benefit: Ensures consistent feeding and eliminates misalignment issues that can stall production lines.

2. Initial Compression Stage

Once the sofa is in position:

Hydraulic Compression Plates descend from both sides, applying uniform lateral pressure.
Pressure Control: Programmable HMI settings allow adjustment of compression force, accommodating various frame types and upholstery densities.
Quick Hold: A 3–5 second dwell time secures the compressed shape before rolling begins.

Benefit: Reduces sofa width by up to 50%, cutting down on volumetric weight for freight pricing.

3. Tri-Fold or Bi-Fold Adjustment

Depending on sofa depth and customer requirements, the NG-43RL can perform a tri-fold or bi-fold:

Servo-Driven Folding Arms swing inward to fold the sofa sections.
Fold Angle Programming is stored in job recipes—switch between 120° (tri-fold) or 180° (bi-fold) with one touch.
Adaptive Folding: Real-time feedback ensures fold arms adjust for variations in armrest thickness or cushion protrusion.

Benefit: Versatility to handle sectionals, loveseats, and standard three-seater sofas without manual retooling.

4. Rolling & Stretch Film Wrapping

After folding:

Rotary Drum Rollers cradle the folded sofa and rotate it end-over-end.
Integrated Stretch-Film Dispenser wraps each rotating bundle with tension-controlled film.
Multi-Layer Wrap: Two to three film passes lock the compressed shape for transit.

Benefit: Creates a tight, uniform roll that resists shifting and protects upholstery from moisture and dirt.

5. Sealing & Discharge

Upon completion of the wrap:

Automatic Film Cutter slices the film and affixes the tail end with heat sealing or adhesive tape.
Exit Conveyor Transfer: The finished roll pack is smoothly transferred to the discharge conveyor or palletizing station.
Cycle Time: Full process—from loading to discharge—takes approximately 25–30 seconds per sofa.

Benefit: High throughput of 100+ sofas per hour, enabling just-in-time export scheduling.

6. Palletizing & Logistics Integration

For streamlined export:

Optional Pallet Dispenser places pallets under the roll packs.
Robotic Palletizer Interface can be linked for fully automated stacking.
Labeling Module prints and applies shipping labels or RFID tags.

Benefit: Seamless integration with warehouse management systems (WMS) and freight providers.

Technical & Operational Highlights

Adjustable Compression Pressure: 0–500 kN range for different sofa constructions.
CE-Certified Safety Guards: Light curtains and emergency stops on all access points.
User-Friendly HMI: Recipe management for quick product changeovers.
Remote Diagnostics: IoT module enables real-time monitoring and preventive maintenance alerts.
