Zero waste target: A new integrated system for laser marking cans

Magnoni, the LM-group brand, has developed the latest version of its integrated system for laser marking empty beverage cans.  This system enhances the performance of its predecessor, thanks to the integration of an additional control ''station''.

The system operates by first receiving the product accumulated in a single lane which flows on the vacuum belt. Aspiration occurs from below via a system that ensures the cans remain stable along their path, aiding their progression through the initial control station where the inside and rim of the cans are monitored. After this step the cans are taken over by the following transport system which have the aspiration from above.

This method ensures the laser system can mark products on the bottom.

Each control phase has a dedicated waste system, with traceability managed by encoders. This ensures precise control and minimizes all forms of waste.

The can row proceeds on the subsequent belt where aspiration is reintroduced from below, as in the initial stage. Technically, this ensures the cans are stabilized before they proceed to the next phase of production.

An Italian multinational has invested in this system, which can process up to 90,000 cans per hour, or 30,000 more than its previous version.

With two control "stations" and corresponding groups for handling non-compliant cans, waste is reduced. The two control phases are distinct: one is dedicated to the can's integrity, while the other is focused on the marking process. This system allows the equipment to achieve greater precision and efficiency.

For added safety, two side doors prevent from tampering and protects from the laser system. In terms of software, the machine is compatible with any model of industrial vision system.
