Product positioning
This is a dynamic weighing device specifically designed for production lines or logistics sorting lines that handle medium-weight items and require manual intervention. Building on standard dynamic weight-checking functionality, it integrates automatic stop-and-go process control, enabling a seamless combination of automated weighing and manual operations such as barcode scanning, labeling, visual inspection, and record-keeping.
Core workflow
Dynamic Weighing: Items (such as boxes, bags, or pallets) are smoothly conveyed by a belt conveyor into a high-precision weighing section, where rapid and accurate weight measurements are completed without any interruption (weighing capacity up to 100 kg).
Automatic stop and judgment: After the weighing is completed, the control system immediately processes the data.
Automatic determination is performed based on the preset qualified weight range.
Whether the item is qualified or not, or even if no judgment is required, it is automatically conveyed to the designated “manual operation station” and accurately stops there, ensuring that the item comes to rest in a position that is convenient for workers to handle.
Manual Operation Phase: At this stage, the conveyor is in standby mode. Operators can perform a series of manual operations, such as:Scan the item’s barcode or QR code to link weight data.
Paste the pass/fail label.
Perform visual inspections or simple repairs.
Record abnormal information.
Manual Trigger Continue: After the worker has completed all operations, simply press the “Continue” button—typically located next to the workstation—and the conveyor will immediately start, transporting the item to the next stage (such as the flow path for合格品, the rejection chute for不合格品, or the next workstation).
Main Components and Features
Belt conveyance: Compared to roller conveyors, belt conveyors offer smoother operation and are vibration-free. They are particularly well-suited for items with uneven bottom surfaces, soft packaging, or those requiring precise alignment. Moreover, during an emergency stop, items won't roll due to inertia.
High-rigidity weighing bridge and sensors: Optimized specifically for a 100 kg capacity, these components offer exceptional resistance to off-center loading and vibration, ensuring high repeatability even under dynamic conditions (typically reaching ±10–50 g, depending on the configuration).
Intelligent Control System:
The core component is a high-performance checkweighing instrument, responsible for high-speed computation and process control.
Set up a “stop positioning” program to ensure that the stopping position is consistent every time.
Equipped with dual-button controls (“Emergency Stop” and “Continue Start”), it is safe and reliable.
Human-computer interaction interface:
The large-size touch screen displays information such as weight, judgment results, and cumulative counts in real time.
You can easily set parameters such as weight limits and stop delays.
Flexible interface: It can connect to barcode scanner signals to automatically associate weight data with barcode information, and via communication interfaces (such as Ethernet or RS485), it can upload data to MES or ERP systems.
Core Application Scenarios
This design is particularly suitable for the following processes:
Quality Inspection and Data Traceability: After weighing, operators manually scan codes to link product serial numbers with precise weights, enabling end-to-end quality traceability.
Composite Process Station: At the logistics center, after parcels are weighed, they require manual safety inspections, reinforced packaging, or special labeling.
Pre-sorting and Diversion Processing: As the front end of a fully automated sorting line, this stage involves manual operators who, based on weight information and visual inspection, determine which channel the item should be routed to (e.g., different carriers).
Semi-automatic handling of heavy-duty products—such as chemical raw materials, pet food, construction materials, and other large-packaged goods—may require manual sealing or sample inspection after weight verification.
Value delivered to the customer
Process Optimization: Perfectly combines the high efficiency of dynamic weighing with the flexibility of manual operations, eliminating bottlenecks in material handling and significantly boosting the overall efficiency of the composite process.
Accurate data: This eliminates errors and inefficiencies caused by manual handling and weighing on platform scales, ensuring that weight data is objective and real-time.
Reduce labor intensity: Items are automatically conveyed and precisely positioned within easy reach of workers, eliminating the need for workers to lift heavy objects and ensuring compliance with ergonomic principles.
Error-proofing and traceability: The system enforces a “weighing—stop—scan code” process to prevent missed inspections and scans. All data is digitized, facilitating quality management and analysis.
In summary, this 100-kg belt-type dynamic weighing machine is not just a weighing device—it’s also an intelligent process-control node. By employing a closed-loop process of “automatic weighing → precise pause → manual operation → button-activated resumption,” it provides an ideal solution for complex production processes that require human-machine collaboration.
