Automatic Checkweigher Systems for Inline Weight Control
Our automatic checkweigher portfolio verifies product weight in motion to support label claims and reduce giveaway. These systems integrate into new or existing packaging lines across food, pharmaceutical, and industrial plants.
How an Inline Weigher Works
Products pass over high-stability load cells while DSP and microprocessor filtering reduce vibration and product effects. Phase-adapted compensation and small-target algorithms stabilize readings at speed.
Ejection options—air blast, pusher, drop flap, or stop-on-reject—remove under- or overweight items without stopping the line.
Why Choose Our Checkweigher Manufacturer
Proven results: installations since 2002 with documented improvements in line speed, capacity, labor efficiency, and quality pass rates.
Hygienic, compliant builds: SUS304 or SUS316 stainless steel with IP65 protection. Designs align with FDA, HACCP, and GMP. Tool-less belt removal and open profiles simplify cleaning.
Smart controls: 7 multilingual touch screens, guided setup, product recipes, auto zero, and production statistics. USB updates complete in minutes.
Reliability and maintenance: modular frames, wear-resistant parts, energy-efficient drives, and standardized spares help reduce service time.
Types and Configurations
Standard inline unit for packaged goods: pouches, trays, bags, and bottles with tailored ejection for product fragility.
High-precision micro-weight model: for sachets and small bottles; supports tight giveaway limits.
Heavy-duty carton/case weigher: reinforced frames for boxes, bundles, and cases before palletizing.
Combination weighing + inspection: integrated metal detection or X-ray with shielding and synchronized signals to reduce interference.
Multi-lane and multi-weight sorter: verifies each lane and routes under/target/overweight items for rework or optimization.
Washdown versions: sealed electronics and components for wet or high-moisture zones.
Key Features of the Weight Checking System
Accuracy at speed: adaptive filtering, DSP processing, and phase compensation for stable readings.
Throughput without compromise: optimized conveyor geometry and fast ejection support high line speeds.
Fast changeover: recipe-based setup, guides, timing screws, and hold-downs for unstable packs.
Connectivity and data: Ethernet/IP, Modbus/TCP, OPC UA, plus USB export for batch reports and audit trails.
Mechanical reliability: modular design, quick-release belts, and standardized spares.
Safety and precise removal: guarding, interlocks, lockable bins, and synchronized timing reduce collateral rejects.
Applications
Food & beverage: snacks, pet food, pasta, frozen foods, seafood, fruits, and vegetables.
Pharmaceutical & healthcare: bottles, blisters, sachets with audit trails to support GMP.
Industrial & consumer goods: verify counts or missing parts in kits and personal care items; end-of-line carton checks.
Technical Snapshot (model-dependent)
Weight range: a few grams to tens of kilograms.
Accuracy: tuned to product size and line speed.
Throughput: single-lane or multi-lane formats.
Construction: SUS304/SUS316; IP65 (higher ratings on request); food-grade, quick-release belts.
Electrical & I/O: standard industrial power; digital I/O, encoder inputs, reject confirmation sensors.
Networks: Ethernet/IP, Modbus/TCP, OPC UA; USB for data and upgrades.
Removal methods: air, pusher, flap, diverter, or stop-on-reject with lockable bins.
Line Integration and ROI
These weighing systems link upstream with fillers or VFFS and downstream with metal detectors, X-ray, labelers, and case packers. Real-time feedback can adjust fillers or augers to hold average weight on target and reduce overfill.
Service and Support
We provide commissioning, product calibration, and operator training. Preventive maintenance, wear kits, and remote diagnostics help sustain performance. Software updates are fast, and multilingual interfaces ease use across shifts.
FAQs
Q: How do I choose the right checkweigher?
A: Match product size, weight range, target accuracy, and line speed. Consider belt dimensions, ejection style, hygiene class, and data integration needs.
Q: Can the system handle wet or frozen products?
A: Yes. Washdown versions with sealed electronics and IP65/66 protection suit seafood and frozen foods.
Q: What factors affect accuracy on an in-motion scale?
A: Product stability, belt condition, vibration, and temperature. Adaptive filtering, guides, and hold-downs help mitigate these.
Q: How is compliance and traceability supported?
A: The system records each weighment and reject event. Data exports via USB or network support audit trails aligned with GMP and HACCP.
