How a Labeling Machine Works
Labeling machines are essential in various industries, including food and beverage, pharmaceuticals, cosmetics, and manufacturing. They apply labels to products, containers, packages, or bottles. Here's a step-by-step explanation of how a typical labeling machine works:
Product Feeding
Products are fed onto a conveyor belt or into a labeling station. This can be done manually or automatically. The conveyor belt ensures a steady flow of products into the labeling area.
Label System
Labels are supplied in rolls or sheets, depending on the machine type. Haizhou Machinery generally uses a roll-to-roll labeling system
Label Positioning
The machine uses sensors to detect the product's position and synchronize the label application. These sensors ensure that the label is applied in the correct position on each product.
Depending on the label type, such as paper labels, transparent labels, etc., different types of sensors will be required.
Label Application
The label applicator, which can be a tamp-blow, wipe-on, or air-blow system, applies the label to the product. The applicator dispenses the label onto the product surface, ensuring it adheres correctly.
Tamp-Blow: A tamp pad presses the label onto the product using a combination of pressure and air.
Wipe-On: A roller or brush wipes the label onto the product.
Air-Blow: The label is blown onto the product using a burst of air.
Haizhou labeling machine generally uses the Wipe-On method for labeling.
Adhesion and Alignment
After the label is applied, additional rollers or brushes may ensure the label is firmly adhered and aligned correctly. This step helps to eliminate wrinkles or bubbles that may form during the application.
Product Discharge
Once labeled, the products continue on the conveyor belt for further processing or packaging. The machine may also have a rejection system that removes products with improperly applied labels.
Control System
Modern labeling machines are equipped with control systems that monitor and adjust the labeling process. These systems can include touchscreens for easy operation, programmable logic controllers (PLCs), and connectivity for integration with other production line equipment.
Optional Features
Some labeling machines may include additional features such as printers for batch numbers or expiration dates, vision systems for label inspection, and various label types (e.g., self-adhesive, shrink sleeve, wrap-around).
Labeling machines increase efficiency, accuracy, and consistency in applying labels to products, which is crucial for branding, compliance, and inventory management.
