Automatic Multi Slabs Palletizer Machine For Stone Slab Stacking

This automatic multi slabs palletizer takes over the stacking work at the end of your production line: instead of moving and stacking stone slabs one piece at a time by hand, it grips and stacks several slabs in a single cycle. Labor costs drop, material collection at the line end speeds up, and the chipping and collision losses typical of manual handling are largely avoided. A servo drive keeps every movement precise and stable so that stacked slabs sit neatly and uniformly, while the PLC electronic control system links seamlessly with upstream machines such as cutting and polishing lines to form one continuous automated production line.

• Multi-Slab Synchronous Palletizing – Grips and stacks multiple stone slabs in one cycle, replacing piece-by-piece manual handling. End-of-line staffing and on-site management costs go down, and the steady, controllable cycle supports long-duration continuous operation that keeps pace with high-capacity processing lines and removes end-of-line bottlenecks.
• Synchronous, Smooth Movement That Protects the Slabs – Synchronous lifting and placement logic keeps the load even and the motion impact-free. Common handling damage such as knocks, edge chipping and corner breakage is prevented, cutting product loss and rework while protecting the appearance quality and pass rate of every slab.
• Servo-Driven Precision – Key motion axes use servo drives paired with high-precision transmission for fast response and accurate positioning. Multiple slabs stay consistently aligned during synchronous operation and stack in neat order. The system holds its palletizing accuracy even under the dusty, heavy-load conditions typical of stone processing plants, keeping failure rates and maintenance costs low.
• PLC Compatibility for Fast Line Integration – A PLC-based control system with standard industrial communication interfaces integrates with upstream and downstream equipment such as cutting, polishing and chamfering machines, so a fully automated line from raw material to stacked finished product can be set up quickly, with automated material transfer and data exchange between processes.
• Customization and OEM/ODM Support – Equipment parameters, palletizing logic and complete solutions can be tailored to your slab sizes, line cycle times and plant layout. OEM and ODM partnerships are welcome for equipment integrators, stone brands and export distributors.

Working Example – End-of-Line Slab Palletizing

1. Receive: finished slabs leave the cutting or polishing line and reach the palletizing station.
2. Grip: the servo-driven gripping frame lowers and lifts several slabs synchronously in a single cycle (about 30 seconds per cycle, model LDFJ5300).
3. Transfer: the load stays even and impact-free along the 1450 mm lift stroke and 3500 mm travel path, so slabs arrive without knocks, edge chipping or corner breakage.
4. Stack: slabs are set down neatly and uniformly on the pallet; the PLC keeps the machine in step with upstream and downstream equipment for continuous flow.

Machines handle slab packages from 300×300 mm up to 1200×500 mm within the 300 kg loading capacity, replacing the manual stacking crew at the end of the line and keeping precision over long shifts even in high-dust plant conditions.
