Automated labeling of cylindrical and conical containers requires specialized product handling to ensure label alignment and adhesion across varying diameters. The Multivac L 320 conveyor belt labeler addresses these technical challenges through a modular design that integrates product convergence, alignment, and robust guiding systems. This technology is particularly relevant for the chemical, pharmaceutical, and automotive industries, where precision in the digital supply chain is essential for traceability and regulatory compliance.
Technical Alignment and Multi-Surface Labeling
The L 320 series was showcased at ACHEMA 2022 in Frankfurt, Germany, where it demonstrated its capability to handle round or oval bottles, pots, and glass jars. The system utilizes a precise product convergence mechanism on the transport conveyor to align containers before they reach the labeling station. This alignment is critical for wrap-around labeling, front and back application, and the placement of sealing labels.
To maintain label integrity at high cycle rates, the machine is equipped with servo technology that synchronizes the dispensing speed with the conveyor motion. Measurable accuracy is further supported by various optional press-on devices, ensuring consistent adhesion even on tapered surfaces.
Integration and Digital Process Reliability
The labeling solution is designed for seamless integration into existing production lines or as a standalone unit for smaller operations. Through the HMI (Human Machine Interface), operators can centrally control the labeling, printing, and inspection processes. This integration supports the digital supply chain by allowing the automatic loading of print layouts and the storage of setting parameters in specific recipes, which significantly reduces conversion times during batch changes.
Optional modules enhance process reliability through integrated inspection technology. These systems perform comprehensive checks for label presence, barcode readability, and pattern recognition. Additionally, the inclusion of thermal transfer, thermal inkjet, or continuous inkjet printers allows for the application of variable data—such as best-before dates and batch numbers—directly during the labeling cycle.
Performance and Sustainability Metrics
The modular construction of the L 320 allows it to be adapted to specific industry standards, including various hygiene levels. By using standard components, the system offers high availability and low maintenance requirements. For high-output environments, the "zero downtime" function enables uninterrupted production by integrating multiple label dispensers that switch automatically when a roll is exhausted.
In terms of material efficiency, the system supports a wide range of label materials and formats. When compared to manual or less precise mechanical labeling, the high-precision servo control reduces material waste and ensures that labels are applied exactly at the intended position, supporting sustainable manufacturing goals by minimizing rejects.
