How to Troubleshoot Common Issues with Automatic Multihead Weighers

Automatic multihead weighers are sophisticated machines that can quickly and accurately weigh and package products. However, like any machine, they can occasionally encounter issues. This article will guide you through troubleshooting some of the most common issues with automatic multihead weighers and provide solutions to get your machine back up and running smoothly.

Feed Issues

– Product is not being fed consistently into the weigher. Check the product hopper to ensure that it is full and that the product is flowing freely. Inspect the feed conveyor for any blockages or damage. Adjust the feed rate if necessary.

– Product is bridging or sticking in the hopper. Try using a vibrator or agitator to loosen the product. Ensure that the hopper is designed for the specific product and that it is not too large or too small.

Weighing Issues

– Weigher is not weighing accurately. Calibrate the weigher according to the manufacturer’s instructions. Check the load cells for damage or misalignment. Ensure that the weigh pans are clean and free of debris.

– Weigher is overweighing or underweighing consistently. Adjust the target weight setting in the weigher’s control panel. Check the weighing algorithm and ensure that it is appropriate for the product being weighed.

Discharge Issues

– Product is not being discharged properly from the weigher. Inspect the discharge chute for any blockages or damage. Ensure that the discharge gate is opening and closing properly. Adjust the discharge speed if necessary.

– Product is leaking from the weigher. Check the seals around the discharge chute and weigh pans for damage or wear. Replace any worn or damaged seals. Tighten any loose bolts or screws.

Electrical Issues

– Weigher is not powering on. Check the power supply and ensure that it is connected properly. Inspect the electrical connections for any damage or loose wires. Reset the weigher’s circuit breaker or fuse.

– Weigher is experiencing intermittent power outages. Identify the source of the power outages by checking the electrical supply, wiring, and connections. Contact a qualified electrician if necessary.

Mechanical Issues

– Weigher is making strange noises. Inspect the weigher for any loose or worn parts. Lubricate any moving components as per the manufacturer’s recommendations. Check the drive system for any damage or misalignment.

– Weigher is vibrating excessively. Balance the weigher by adjusting the leveling feet. Inspect the weigher’s frame for any damage or loose bolts. Reduce the weighing speed if necessary.

By following these troubleshooting steps, you can quickly identify and resolve the most common issues with automatic multihead weighers. If you are unable to resolve the issue yourself, contact the weigher manufacturer or a qualified technician for assistance. Regular maintenance and calibration can help prevent future issues and ensure the optimal performance of your automatic multihead weigher.
