Labelling Machinery: Troubleshooting Tips

Labelling machinery plays a crucial role in many industries, from food and beverage to pharmaceuticals and manufacturing. These machines are responsible for applying labels to products accurately and efficiently. However, like any mechanical equipment, labelling machines can encounter issues that disrupt production. In this article, our experts explore some common labelling machine problems and provide troubleshooting tips to help you keep your production line running smoothly.

Misaligned Labels

One of the most common issues with labelling machinery is misaligned labels. When labels are not applied precisely to the product surface, it can result in a waste of materials and compromised product presentation. Here’s how to troubleshoot this problem:

• Check Label Alignment Sensors: Ensure that the label alignment sensors are clean and properly positioned. If they are dirty or misaligned, the machinery may not be able to detect the correct position for label application.
• Inspect Label Roll Alignment: Make sure the label roll is correctly loaded and aligned. Misaligned label rolls can lead to skewed label placement.
• Calibrate Labelling Head: If misalignment persists, calibrate the labelling head according to the manufacturer’s instructions. This may involve adjusting settings for label placement accuracy.

Label Jams

Label jams occur when labels get stuck or tangled within the machinery, causing downtime and potential damage to the equipment. To troubleshoot label jams:

• Clear Obstructions: Shut down the machine, and carefully remove any stuck labels or debris from the label path. Ensure that there are no loose label fragments inside the machinery.
• Check Label Roll Tension: Improper label roll tension can contribute to label jams. Adjust the tension according to the manufacturer’s recommendations to prevent future jams.
• Regular Maintenance: Implement a regular maintenance schedule to keep the labelling machinery in optimal condition. Lubricate moving parts and replace worn-out components to reduce the risk of jams.

Wrinkled or Folded Labels

Wrinkled or folded labels can result in a less-than-professional appearance for your products. To address this issue:

• Check Label Material Quality: Ensure that the label material is of high quality and suitable for the labelling machine. Inferior materials may be more prone to wrinkling or folding during application.
• Inspect Label Application Speed: Adjust the labelling machine’s speed to match the label material’s thickness and flexibility. Slower speeds can reduce the likelihood of wrinkles.
• Label Tension Control: Some labelling machines offer tension control features that can help prevent label wrinkling. Adjust the tension settings as needed.

Inconsistent Label Adhesion

Inconsistent label adhesion can result in labels peeling off or not adhering properly to products. To troubleshoot this problem:

• Check Label Adhesive Quality: Ensure that the adhesive used on the labels is of the correct type and quality for the product’s surface. Different materials may require different adhesives.
• Clean the Product Surface: Make sure the product surface is clean and free of any contaminants, such as dust or oils, that could hinder label adhesion.
• Adjust Label Pressure: Some labelling machines allow you to adjust the pressure applied during label application. Experiment with different pressure settings to find the optimal one for your labels.
  

Inaccurate Label Placement

When labels are not applied precisely to the designated area on a product, it can lead to aesthetic issues and potential legal compliance problems. To troubleshoot inaccurate label placement:

• Check Label Sensors: Verify that the label sensors are functioning correctly. If they are dirty or malfunctioning, they may not detect the correct label placement position.
• Inspect Labelling Head: Examine the labelling head for any damage or misalignment. If necessary, calibrate or realign it to ensure accurate label placement.
• Review Labelling Machine Settings: Double-check and adjust the labelling machine’s settings, including label size, position, and speed, to match the requirements of your products.
