Say Goodbye to Large Footprints, Mandatory Safety Fences, Complex Teach Pendant Programming, and Difficult Line Relocation: Experience Safe Human-Robot Coexistence, Flexible & Rapid Deployment Intelligent Palletizing
The Collaborative Robot Palletizing System (Cobot Palletizer) (integrating high-payload cobot arm $\rightarrow$ safety sensing & collision detection system $\rightarrow$ modular flexible end-of-arm tooling (EOAT) $\rightarrow$ intelligent no-code palletizing algorithm software $\rightarrow$ pallet/box positioning sensors $\rightarrow$ high-precision flexible palletizing output) is an industrial-grade flexible automation assistant engineered to solve end-of-line packaging pain points such as palletizing labor shortages, extreme physical fatigue, massive footprints and mandatory safety enclosures of traditional industrial palletizers, frequent line changeovers for high-mix low-volume production, and tight workshop space constraints.
LANTU Machinery introduces an integrated fully automatic cobot palletizing solution. Equipped with a lightweight high-payload cobot arm, supported by vision/photoelectric precision positioning and no-code graphical palletizing software, it performs millisecond-level collision sensing in open workspaces—enabling safe human-robot collaboration without rigid safety fences. Whether handling cartons, bagged materials, liquid drums, plastic crates, or boards, it delivers high sensitivity, optimal space utilization, and diverse pattern stacking (such as interlocking, pinwheel, or column stacks).
As a source packaging and palletizing machinery manufacturer, LANTU Machinery has designed this system—covering inverse kinematics, collision torque monitoring, trajectory smoothing, and pattern generation—to be as intuitive as a smartphone app. Operators simply drag to teach or select box and pallet dimensions via a 3D graphical user interface, and the system automatically calculates optimal stacking trajectories. Occupying a minimal footprint of only 1.5–2.0 square meters, offering one-touch forklift relocation, and providing plug-and-play capability, it helps factories save space, labor, time, and hassle.
Choosing a reputable source manufacturer is crucial for your end-of-line automation upgrade. LANTU Machinery’s mature cobot palletizing algorithms and modular hardware engineering ensure your packaging line achieves high-efficiency closed-loop operation, rapid commissioning, and long-term stability.
Core Components and Three System Safeguards (LANTU Precision Parts)
Our collaborative robot palletizing systems are fully equipped with industry-leading core components, ensuring operational safety, high accuracy, and an ultra-long service life.
1. Cobot Arm Body & Safety Collision Safeguards
High-Payload / Long-Reach Cobot Arms: Available in 10kg / 12kg / 16kg / 20kg / 25kg / 30kg payload specifications with working radii ranging from 1300mm to 1900mm, fully meeting standard pallet dimensions (e.g., 1200×1000mm, 1100×1100mm) and high-stack requirements (stacking heights up to 1.8m–2.2m with elevation columns).
High-Sensitivity Joint Torque Sensors: Features 10-level safety collision detection that automatically brakes and stops within milliseconds upon contacting humans or obstacles, eliminating the need for physical safety fences while satisfying safety compliance standards.
Expandable Servo Elevation Column (Z-Axis): Optional servo-controlled synchronous elevation column dynamically adjusts the cobot base height during stacking, extending native arm reach to easily handle tall stacks over 2.2 meters.
2. Modular Multi-Function End-of-Arm Tooling (EOAT)
Flexible Vacuum Grippers: Ideal for standard cartons, display boxes, and flat boards, utilizing foam pads or multi-suction cup arrays to securely grip irregular or porous carton surfaces for single or multi-box pick-and-place.
Mechanical Pneumatic Clamps: Designed for open-top boxes, plastic crates, or heavy containers, utilizing side-clamping or bottom-support mechanisms to ensure secure handling without box damage.
Bag Grippers (Pneumatic / Electric): Tailored for granular or powder bags, utilizing bottom-supporting claws or pin-plates to manage flexible bag deformation during stacking.
3. Intelligent Palletizing Software & Guidance System
No-Code 3D Graphical Interface: Integrated 7-inch / 10-inch industrial touchscreen or mobile tablet terminal with an interactive 3D stack designer. Users input box dimensions (L×W×H), pallet size, and layer count, and the software generates optimal trajectories and stacking patterns within 1 minute.
Dual-Pallet Alternate Stacking: Supports Station A / Station B dual-pallet layouts. When Pallet A reaches full capacity, the cobot seamlessly switches to Pallet B without stopping production, allowing operators to safely clear Pallet A for uninterrupted continuous operation.
Automatic Sheet Placement (Optional): Optional side-mounted slip-sheet grippers automatically retrieve and place cardboard interleavers between specified layers to enhance stack stability.

Comprehensive Pre-Shipment Simulation & Live Testing: Every system undergoes full-load continuous motion and stack stability testing using customer-specific box samples and pallet layouts prior to shipment.
What Factors Should You Consider When Purchasing?
Single Package Weight & Speed Target: What is the weight of a single box/bag (kg)? What is the required speed in boxes/bags per minute? (Standard cobot palletizing speeds range between 6 and 13 cycles/min; for ultra-high speeds exceeding 15 cycles/min, traditional industrial robots may be considered).
Pallet Dimensions & Stacking Height: What are your standard pallet dimensions (e.g., 1200×1000mm)? What is the maximum target stack height? (Determines whether a Z-axis servo elevation column is required).
Workshop Environment & Power Supply: Are there explosion-proof or dust-proof requirements (e.g., powder industries)? Is the site power supply single-phase 220V or three-phase 380V?
Infeed Conveyor Interfacing: Is the incoming product flow continuous or intermittent? Are infeed indexing mechanisms or lane dividers needed?
Frequently Asked Questions (FAQ)
Q1: Does a cobot palletizer truly operate safely without a fence? What if it hits an operator?
Answer: Yes, it is designed for fence-free operation. Cobots incorporate advanced joint force sensors and electronic safety stop systems. If the joint detects an external force exceeding preset thresholds (such as contacting a person), the system stops within milliseconds without causing injury. For high-traffic areas, optional Safety LiDAR sensors can be added to slow down the robot when people approach and automatically resume full speed when the area is clear.
Q2: How complicated is it to reconfigure patterns when switching carton sizes?
Answer: Extremely simple. LANTU Machinery systems feature intuitive 3D graphical palletizing software. When switching carton sizes, operators simply enter the new box dimensions (L×W×H) and weight on the touchscreen. The software automatically calculates optimized stacking trajectories and layer patterns, completing changeover in under 3 minutes without writing code.
Q3: What is the stacking speed of a cobot palletizer compared to traditional industrial robots?
Answer: Cobots prioritize safety, compactness, and flexibility with moderate speeds. Paired with high-efficiency grippers, cobot palletizers operate at 6 to 13 cycles per minute (speeds can double when picking multiple boxes per cycle). Traditional industrial robots offer higher speeds (15–25 cycles/min) but require large footprints and rigid safety enclosures. For the majority of small-to-medium packaging lines, cobot palletizers provide an exceptionally high return on investment.
