In modern packaging operations, speed and precision are non-negotiable. That’s why 10 heads multihead weighers have become essential equipment in food processing, pharmaceuticals, chemicals, and more. These machines offer fast and accurate weighing of bulk and granular products, optimizing both efficiency and product consistency.
However, like any complex machinery, they can occasionally run into problems. Understanding how to troubleshoot common issues is essential to minimize downtime and maintain production flow.
Before diving into troubleshooting, it’s important to understand why consistent maintenance is crucial.
Prevents unplanned downtime that can disrupt the entire production line.
Protects your investment by extending the life of the machine.
Improves weighing accuracy, which reduces product giveaway and increases customer satisfaction.
Ensures safety in high-speed operations.
Regular maintenance helps detect small issues before they become major failures, saving time, money, and frustration in the long run.
The machine is over-dispensing or under-dispensing product.
Increased product giveaway or packaging that does not meet label claims.
Frequent customer complaints about inconsistent product weights.
Calibration Errors – The weigher may lose calibration due to vibrations, environmental changes, or aging sensors.
Product Residue Build-Up – Sticky or oily products may leave residues in the buckets, affecting actual net weight.
Faulty Load Cells – Load cells may wear out or become damaged, giving incorrect weight data.
Unstable Product Flow – Irregular or inconsistent product feeding from the top can skew weighing accuracy.
Calibrate regularly using certified weights. Always recalibrate after moving or servicing the machine.
Clean all hoppers and contact surfaces after each production run, especially when switching products.
Check load cells for wear or damage. Replace if they no longer respond accurately to known weights.
Adjust feeding equipment such as vibrating feeders or conveyor belts to ensure steady product flow.
Product remains stuck in weighing buckets.
Buckets do not open at the right time, disrupting packing cycles.
Incomplete discharges or repeated errors in filling pouches.
Mechanical Wear or Misalignment – With frequent use, parts like hinges and linkages wear down.
Pneumatic Failures – Air cylinders or valves that control the hoppers may lose pressure or become blocked.
Timing Errors in Software – Software misconfiguration can cause hoppers to open too soon or too late.
Inspect the bucket hinges, arms, and latches for signs of wear and tear. Lubricate or replace components as needed.
Check the pneumatic system: make sure air hoses are free of leaks and the compressor is working at the correct pressure.
Review software settings and delay timers in the control panel. Make sure each bucket opens in the correct sequence.
Weighing cycles take longer than expected.
Production output is lower than the designed capacity.
Machine takes a long time to find the right combination.
Incorrect Settings – Machine parameters may not be optimized for the current product.
Insufficient Feeding – The product is not reaching the weighers fast enough.
Product Characteristics – Sticky or irregular products may not flow easily into the buckets.
Overloaded or Underutilized Combination Logic – The algorithm takes too long to find the right mix of buckets to match the target weight.
Optimize machine settings like target weight range, permissible combination limits, and timing intervals.
Improve feeding systems: increase the vibration intensity or use additional feeders to maintain a steady flow.
Install product-specific feeders or agitators if working with sticky, clumping, or lightweight materials.
Update the combination algorithm in the machine software or consult the manufacturer for fine-tuning.
The HMI (Human Machine Interface) is unresponsive.
Error codes appear without clear cause.
System freezes or reboots intermittently.
Software Corruption – Sudden power loss or outdated firmware may corrupt the operating system.
Electrical Faults – Loose cables, surges, or grounding issues can affect display performance.
Physical Damage – Cracked screens or water ingress into the control panel.
Perform a hard reboot of the system. If the issue persists, consider reloading the firmware.
Inspect wiring connections for damage, wear, or improper grounding.
Replace the touchscreen unit if there’s visible damage or persistent malfunction.
Install surge protectors to guard against voltage spikes.
Product is falling outside buckets or getting stuck.
Frequent need to pause the machine and manually clear obstructions.
Irregular flow between feeders and the weigher.
Misaligned Buckets or Chutes – Parts out of position can misdirect product flow.
Improper Product Type – Some machines are not suitable for large, sticky, or delicate products.
Feeding Speed Too High – Overfeeding can overload weigh buckets and cause spillage.
Re-align all mechanical components like chutes and hoppers. Tighten any loose bolts or frames.
Use product-specific accessories such as anti-stick coatings or baffles.
Adjust feeder speed and product drop angles to maintain smooth transfer without overflow.
To avoid recurring issues, set a consistent schedule for inspecting and servicing your 10 heads multihead weigher.
Clean buckets, hoppers, and contact parts.
Inspect for visible damage, misalignment, or residue.
Monitor weighing accuracy during production.
Lubricate moving parts.
Check pneumatic and electrical systems.
Test load cell responsiveness with control weights.
Full calibration with certified weights.
Review software settings and update firmware if available.
Check feeder alignment and vibration levels.
Replace worn parts and seals.
Perform full system diagnostics.
Train staff on machine use and troubleshooting.
Train operators regularly to spot early warning signs and respond promptly.
Keep a logbook of errors, malfunctions, and maintenance actions for tracking patterns.
Work with the manufacturer for access to software updates, replacement parts, and expert support.
Install backup power systems to prevent data loss or damage during outages.
