Automatic Checkweigher Systems for Inline Weight Control
These systems deliver dynamic weighing on moving conveyors to keep packs within target weight while protecting throughput. They integrate with forming, filling, sealing, cartoning, and palletizing equipment and automatically verify, sort, and reject items that fall outside set limits.
Suitable for bags, pouches, trays, bottles, cartons, and net or mesh packaging across food, pharma, chemical, and logistics operations.
Key Benefits
- Stable accuracy at speed: Rigid frames and refined algorithms maintain repeatable results under vibration and product variation, supporting weight compliance on lightweight sachets and fast-moving snack packs.
- Hygienic and durable: SUS304 or SUS316 stainless steel frames with IP65 options and food-grade belts support washdown requirements for fresh produce, seafood, and protein lines.
- Easy operation and low upkeep: Multilingual touch HMI, recipe libraries, and modular conveyors simplify changeovers. Tool-less belt removal and energy-efficient drives reduce maintenance time.
- Compliance and traceability: Built-in statistics, reject logs, and links to plant systems enable data capture and audit trails. Optional printing/labeling and feedback signals help upstream fillers maintain target weights.
Configurations and Reject Options
- Conveyor formats: Flat-belt, roller-top, and guided belts suit bags, pouches, trays, bottles, and cartons. Guides and timing belts stabilize tall or irregular items for consistent results.
- Pusher rejection: Side pushers divert heavier bags, trays, or boxes into a reject lane with reliable handling.
- Air-jet rejection: Fast air nozzles remove lightweight sachets and flow-wrapped snacks with minimal impact.
- Flap or drop-gate: Gentle mechanisms for fragile packs such as baked goods, blister packs, or bottles.
- Combination units: Integrate weight verification with metal detection or X-ray inspection to save floor space and consolidate controls.
Industry Applications
- Fresh produce and prepared foods: IP65 options and smooth surfaces maintain hygiene while controlling weight on variable-size items.
- Snacks and pet food: Works with multihead or linear weighers upstream and VFFS or flow-wrappers downstream to sustain high-speed changeovers.
- Frozen foods and seafood: Low-temperature compatible belts and stainless structures resist corrosion and condensation in cold or wet areas.
- Pharmaceuticals and chemicals: Tight tolerances, recipe control, and traceability support regulated processes; optional enclosures and guarding enhance safety.
- Warehousing and logistics: Industrial units verify parcel and carton weights for fulfillment, cost control, and automated sortation.
Line Integration and Controls
These systems connect to fillers, multihead weighers, sealers, labelers, case packers, and palletizing robots. PLC integration, fieldbus connectivity, and recipe management enable quick changeovers and automatic filler feedback to keep weights on target. When paired with automated inspection and handling, lines have shown meaningful gains in output, reduced manual labor, and high first-pass quality.
Specifications and Options
- Pack sizes: From small sachets and stickpacks to jars, trays, and full cartons.
- Formats: Narrow belts for single-serve items, wide belts for bulk bags, and multi-lane configurations for compact, high throughput.
- Throughput and tracking: Variable-speed drives and encoder-based tracking support consistent weighing and conveyor synchronization.
- Materials and protection: SUS304/SUS316 frames, FDA-compliant belts, IP65 enclosures, guarding, and interlocks for operator safety.
- Service and support: Pre-configured modules, on-site commissioning, training, remote diagnostics, and global after-sales coverage.
FAQ
Q: Which pack types are compatible?
A: The systems handle bags, pouches, trays, bottles, cartons, and net or mesh bags. Guides and belt options help stabilize tall or irregular items.
Q: How does feedback control maintain target weights?
A: The unit sends control signals upstream to adjust fillers based on live weight data. This reduces drift and keeps products within set limits.
Q: What hygiene options are available for washdown lines?
A: SUS304 or SUS316 stainless steel, food-grade belts, and IP65 protection support cleaning procedures common in fresh food and seafood processing.
