Common Problems with In-Line Checkweighers and How to Fix Them
Drawing from industry insights, here are frequent issues that can disrupt In-line checkweigher performance, along with practical solutions. Early detection through routine checks can prevent downtime.
● Mechanical Wear and Tear: Components like load cells, motors, and belts degrade over time, causing inaccurate readings or jams.
Cause: High-volume usage or poor lubrication.
Solution: Inspect and replace worn parts regularly. Lubricate moving parts per manufacturer guidelines to extend lifespan.
● Conveyor Belt Misalignment or Blockages: Products may jam at high speeds, leading to invalid results.
Cause: Uneven product placement or debris buildup.
Solution: Clean belts daily, ensure products are centered, and install sensors for automatic shut-offs.
● Sensor and Electrical Failures: Loose sensors or power interruptions result in data jumps.
Cause: Faulty cables or surges.
Solution: Secure connections, upgrade grounding, and test sensors weekly.
● Software Glitches: Bugs or outdated firmware affect operations.
Cause: Lack of updates.
Solution: Install manufacturer updates promptly; contact support for diagnostics.
For expert troubleshooting, SameGram offers remote diagnostics and on-site repairs with a 12-month warranty and lifetime maintenance. Our combination systems, like those integrating inline checkweighers with metal detectors, minimize these issues through robust design—learn more.

Factors Affecting Checkweigher Combination System Accuracy
Accuracy is the cornerstone of effective checkweighing. Several variables can compromise it, but understanding them allows for targeted improvements.
| Factor | Description | Impact on Accuracy | Mitigation Tips | |||
Environmental Conditions | Temperature fluctuations, humidity (ideal: 30-85%), and vibrations from the line. | Alters load cell signals, causing voltage drops or added weight from vibrations. | Maintain stable conditions; use vibration-dampening mounts and follow manufacturer temperature guidelines. | |||
Product Variations | Inconsistent shapes, sizes, densities, or packaging textures. | Creates shifts or vibrations during weighing. | Standardize products where possible; calibrate for specific variations. | |||
| Conveyor Speed | High speeds reduce measurement time. | Increases errors from dust or instability. | Optimize speed for your setup; our high-speed checkweighers handle up to 180 m/min with ±0.02g precision. | |||
| Mechanical Wear | Loose fasteners, damaged load cells, or worn belts. | Leads to unstable readings. | Schedule regular inspections and part replacements. | |||
| Operational Errors | Improper setup or operator mishandling. | Results in configuration mistakes. | Provide thorough training; SameGram includes online sessions for seamless operation. | |||
By addressing these, you can achieve consistent results. SameGram's R&D-driven algorithms ensure superior accuracy even in challenging conditions, backed by certifications like CE and UL.
5 Basic Tips for Checkweigher Maintenance
To keep your checkweigher running smoothly, incorporate these proven tips into your routine:
1. Regular Cleaning and Inspection: Remove debris from belts, platforms, and sensors to prevent buildup. Inspect for wear daily.
2. Calibration and Verification: Use test weights to verify accuracy; calibrate per schedule to meet standards.
3. Lubrication and Belt Care: Apply lubricants as recommended; check for fraying and tension.
4. Software Updates: Install updates for bug fixes and enhancements.
5. Operator Training: Educate staff on procedures, reporting issues, and documentation.
These practices reduce downtime and extend equipment life. At SameGram, we offer preventive maintenance programs and free sample testing to tailor our checkweighers to your line—request a demo.
Step-by-Step Checkweigher Calibration Procedures
Calibration ensures your checkweigher meets tolerances and regulatory requirements. Follow this process for reliable results:
1. Preparation: Clean the system and ensure stable environmental conditions. Gather certified test weights matching your product range.
2. Zero Scale Setting: Reset to zero without products; enable active zero tracking.
3. Test Weighing: Run known weights through the system multiple times, recording results.
4. Adjustments: Fine-tune load cells or software if discrepancies arise; recalibrate for specific products.
5. Verification and Documentation: Confirm compliance with reports for audits; repeat quarterly or as needed.
Professional services, like those from SameGram, use advanced tools for precise calibration, minimizing giveaway. Our systems require less frequent calibration due to sensitive load cells—discover more.
