Roller Conveyor Scale for Weighing Process
A roller conveyor scale—also known as a roller conveyor weighing system—is a specialized conveyor that integrates a weighing mechanism to measure the weight of items as they pass over or stop on the rollers. These systems are commonly used in logistics, warehouses, manufacturing, and shipping for accurate and efficient in-motion or static weighing of cartons, parcels, or pallets.
What Is a Roller Conveyor Scale?
It is a roller conveyor section with embedded load cells that measure weight. The scale can be part of a gravity roller or powered roller conveyor. Items may be weighed:
- Statically (item stops on the weighing platform)
- Dynamically/in-motion (item is weighed while moving)
Key Features
| Feature | Description |
| Built-in Load Cells | Sensors that measure the weight accurately |
| Digital Display or PLC Output | Shows weight in real time or sends data to a control system |
| Weighing Accuracy | Typically ±0.1% to ±0.5% depending on system design |
| Roller Type | Steel, PVC, stainless depending on application |
| Capacity Range | From 10 kg to 2000 kg or more depending on design |
| Interface Options | RS232, Ethernet, Profibus, Modbus, or USB |
Typical Specifications
| Parameter | Range / Option |
| Roller Width | 300 – 1200 mm |
| Roller Pitch | 75 – 150 mm |
| Weighing Capacity | 10 – 2000 kg or more |
| Platform Size | 400×400 mm to 1200×1500 mm |
| Accuracy | ±0.1 kg to ±0.5% of full scale |
| Power Supply | 110V/220V AC or 24V DC |
| Display | LED or LCD with optional touch screen |
| Data Integration | Barcode scanners, printers, or ERP/WMS systems |
Applications
| Industry | Use Case |
| Courier & Logistics | Weigh parcels before sorting or dispatching |
| Manufacturing | Check weight of products in production or packing lines |
| Warehousing | Validate shipment weights for invoicing |
| Food & Beverage | Portion control and quality assurance |
| Pallet Handling | Weigh full or partial pallet loads |
Types of Roller Conveyor Weighing Systems
| Type | Description | Use Case |
| Static Weighing Conveyor | Item must stop on scale for reading | Shipping accuracy check |
| Dynamic/In-Motion Weighing | Weighs moving items via software filters | Parcel sorting lines |
| Integrated Checkweigher | Compares actual vs. target weight | Quality control systems |
| Heavy-Duty Pallet Scale | Designed for forklift-loaded conveyors | Palletized goods weighing |
