Multihead weighers are widely used in the food packaging industry as they offer fast and accurate weighing of products. However, like any machine or equipment, multihead scale is prone to faults and issues that may affect their performance. Troubleshooting common issues with multihead weighers is essential to ensure that the machine runs efficiently and provides accurate weights consistently. In this article, we, Smartpack, a China multihead weigher packaging machine manufacturer, will discuss some of the most common issues that may arise with multihead weighers and how to troubleshoot them.
1. Product Sticking to the Weighing Surface
One of the most common issues that may occur with a multihead weigher is that the product may stick to the weighing surface, causing inaccurate weights. This can happen due to the product’s moisture content or the presence of static electricity.
Solution: To solve this issue, you should choose the dimple plate for feeding pans, hoppers and discharge chute, which is with many spots on the plate. This desgin can reduce the contact area between food and machine, ensuring the stick food have a smooth flow. Generally we (Smartpack) will take into consideration details, such as the , type of top cone(vibrate or rotary), bucket style (standard or scraper), and even the angle of discharge chute. Additionally, using a non-stick food grade teflon coating on the weighing surface is an option for very sticky products.
2. Inconsistent Weight Accuracy
Another common issue that may arise with a multihead weigher is inconsistent weights. This can happen due to various reasons, such as incorrect calibration, incorrect machine settings, or external influence factors.
Solution: To troubleshoot this issue, you should first check if something hangs around the weigh hoppers. Second, check the load cells condition on touch screen,
then do a right calibration. Additionally, you should also check the machine’s settings and ensure that they are set correctly. If the issue persists, you should check the machine’s parts, such as the load cell and the weigh hopper, and replace them if they are worn out.
3. Material Blockages or Bucket Jamming
Sometimes, the product may get stuck in the hoppers, causing blockages and disrupting the weighing process. This can happen due to various reasons, such as oversized product, incorrect machine settings.
Solution: Every volume of hopper has a limitation for products size. Share you new products size with your multihead weigher supplier, check if your new products can be weighed by same weigher model. Then check the machine’s settings and adjust them to match product, such as the setting of hopper opening time. If the issue persists, you should check if the weigher parts run singularly, if yes please replace the relevant connect parts of them.
4. Excessive Noise
Excessive noise is another common issue that may occur with a multihead weigher. This mainly due to loose bolts, or incorrect machine settings.
Solution: Firstly check the machine’s parts condition, such as the bearings, the motor, and the hoppers, tighten the bolts if necessary or check if the motors turn in the right direction.
5. Inaccurate Product Feeding
When a multihead weigher inaccurately feeds products into its hoppers, it can result in inconsistent weights and disrupt the packaging process. This issue can be caused by factors such as worn-out or misaligned feeders, incorrect settings, or product blockages.
Solution: To troubleshoot this issue, you should first check the feeders and ensure that they are aligned correctly and not worn out. You should also check the machine’s settings and adjust them accordingly. If the issue persists, you should check for product blockages and clear them. Additionally, routine maintenance can help prevent this issue by keeping the machine’s parts in good working condition.
6. Electrical
Electrical issues such as power supply fluctuations, blown fuses, or damaged wiring can cause a multihead weigher to malfunction or stop working altogether. These issues can be caused by factors such as environmental factors, improper installation, or worn-out parts.
Solution: To troubleshoot electrical issues, you should first ensure that the machine is properly installed and that all connections are secure. You should also check for worn-out parts and replace them as needed. Finally, monitoring environmental factors and taking steps to protect the machine from power fluctuations or other electrical issues can help prevent electrical problems from occurring.
In conclusion, the multihead weigher troubleshooting common issues includes product sticky, unaccurate target weight, material blockages, inaccurate products feeding and electrical. These problems are interlinked, they effect the function, speed and accuracy of multihead scale.
