Troubleshooting Common Issues with 14-Head Multihead Weighers

Introduction

14-head multihead weighers are complex machines that can be used to accurately weigh and dispense a variety of products. However, even the most well-maintained weighers can experience occasional problems. This article will discuss some of the most common issues that can occur with 14-head multihead weighers and provide troubleshooting tips for each issue.

Misaligned Weigh Cells

If the weigh cells are misaligned, the weigher will not be able to accurately weigh the products. This can cause the weigher to overfill or underfill the containers, which can lead to product waste or customer complaints. To align the weigh cells, use a level to make sure that the weigher is level. Then, use a screwdriver to adjust the set screws on the weigh cells until the weigher is level.

Faulty Load Cells

If a load cell is faulty, it will not be able to accurately measure the weight of the products. This can cause the weigher to overfill or underfill the containers, which can lead to product waste or customer complaints. To test a load cell, use a weight to apply a known weight to the load cell. Then, use a voltmeter to measure the voltage output of the load cell. The voltage output should be proportional to the weight that is applied to the load cell. If the voltage output is not proportional to the weight, the load cell is faulty and should be replaced.

Clogged Hoppers

If the hoppers are clogged, the products will not be able to flow into the weigh buckets. This can cause the weigher to stop feeding products, which can lead to production downtime. To unclog the hoppers, use a vacuum cleaner to remove any debris from the hoppers. Then, inspect the hoppers for any damage. If the hoppers are damaged, they should be replaced.

Damaged Weigh Buckets

If the weigh buckets are damaged, they will not be able to accurately weigh the products. This can cause the weigher to overfill or underfill the containers, which can lead to product waste or customer complaints. To inspect the weigh buckets, remove the weigh buckets from the weigher and inspect them for any damage. If the weigh buckets are damaged, they should be replaced.

14-head multihead weighers are complex machines, but they are also very reliable. By following the troubleshooting tips in this article, you can quickly and easily resolve any issues that may arise with your weigher.
