Dynamic DWS (Dimensioning, Weighing, and Scanning) System – Precision Down to 1mm
In logistics distribution centers, operations must never pause, and data must always be accurate. The dynamic DWS system is designed to address this: it captures dimensions (length, width, and height), weight, and barcode information simultaneously—all within a single second—while the conveyor line remains in constant motion. The data provided is precise enough to support billing and automated sorting decisions. Yifang Technology’s GM220 and GM220Pro models both share a baseline precision of ±1mm, while offering distinct tiers in terms of throughput capacity and scanning flexibility.
GM220: A Balanced Benchmark for Low-to-Medium Volume Operations
The GM220 is tailored for e-commerce warehouses, regional express delivery hubs, and factory outbound lines handling up to 10,000 parcels per day. It integrates five core functions: dimensioning, dynamic weighing, top-down barcode scanning, photographic documentation, and seamless data integration. As parcels move along the conveyor at a constant speed, the system captures all necessary data in just one second per item—achieving a throughput of 1,500 parcels per hour, which is 5 to 10 times more efficient than manual processing.
Its reliability is twofold. First, it offers consistent precision: utilizing a proprietary parallel-light curtain combined with AI-driven dynamic vision algorithms, the system accurately reconstructs the 3D profiles of various items—including standard cartons, flexible poly-bags, irregularly shaped or bulging packages, and even black or reflective items. It handles dimensions ranging from 10×3×3 cm to 150×80×80 cm, with a weighing capacity of 60 kg, a dimensional accuracy of ±1mm, and a weighing margin of error as low as 10g—effectively minimizing billing disputes related to "dim weight" (volumetric weight) at the source. Second, it ensures operational stability: the industrial modular design minimizes belt vibration and speed fluctuations, supporting 24/7 continuous operation. Data is transmitted directly to WMS/ERP systems, with images strictly linked to specific parcel information, ensuring both cost-effectiveness and full traceability. For small-to-medium-scale production lines that do not require five-sided scanning, the GM220 serves as a well-balanced solution with a low deployment threshold and a short return-on-investment (ROI) period. The GM220Pro eliminates the most expensive manual process on the assembly line through five-sided scanning.
Traditional dynamic DWS (Dimensioning, Weighing, and Scanning) systems typically only read barcodes on the top surface, requiring personnel to manually flip packages to ensure the shipping label faces upward before they enter the line. During peak business periods, this manual flipping becomes a "bottleneck"—labor is wasted on simple, repetitive tasks, often leading to missed scans and operational congestion.
This is where the GM220Pro makes a breakthrough: its five industrial camera arrays perform instantaneous scanning across the front, back, left, right, and top surfaces. Regardless of where the barcode is placed—even on a side edge or corner—the system can read it, no matter the orientation of the package. This boosts the scan read rate from approximately 80% (with single-sided systems) to over 99%. The requirement for labels to be "facing up" is completely eliminated, allowing the equipment to replace the manual flipping station.
Efficiency is also maximized: the system handles 3,000 items per hour and is compatible with high-speed conveyor belts running at 1.5 m/s. It maintains a volumetric accuracy of ±1 mm and a weighing accuracy of 20–50 g, accommodating packages up to 80 × 80 × 80 cm and weighing up to 60 kg, while supporting high-speed operations across 40 induction points.
Tiered solutions without compromising quality: two operational paces built on a unified data foundation.
The difference between the GM220 and the GM220Pro lies not in their accuracy, but in their granularity for specific operational scenarios. The GM220 offers a balanced throughput of 1,500 items per hour, ideal for small-to-medium volume environments, while the GM220Pro—with its five-sided scanning capability and 3,000-item-per-hour throughput—is designed for high-speed sorting lines in large transit centers and cross-border logistics hubs. Both models share the same ±1 mm volumetric accuracy baseline and integrated data connectivity. Data is transmitted in real-time to WMS/ERP systems, with images, dimensions, weight, and barcode information archived together to create a verifiable, traceable audit trail for billing purposes. The value of dynamic DWS (Dimensioning, Weighing, and Scanning) systems lies not in "replacing the tape measure," but in ensuring that the physical data of every parcel on a conveyor line is—for the first time—both reliable enough for billing purposes and actionable for sorting operations. The GM220 offers an optimal price-performance ratio for small-to-medium-scale applications, while the GM220 Pro eliminates the need for manual reorientation—a step that often incurs the highest hidden costs. Rather than offering a "one-size-fits-all" machine, Yifang Technology provides a suite of dynamic data-capture solutions precisely tailored to specific throughput requirements and levels of automation.
