Thermo checkweigher combines code printing and verification

All-in-one Versa RxV system handles 550 bottles/cartons a minute

The all-in-one Versa RxV

Thermo Fisher Scientific’s Versa RxV checkweigher addresses the needs of pharmaceutical and other products that require track and trace capability. The all-in-one high-speed system (up to 550 bottles/cartons a minute) combines code printing and verification (alphanumeric and machine readable) with checkweighing.

‘Pharmaceutical companies, as well as manufacturers of other products such as food and cosmetics, are looking for cost-effective ways to integrate track and trace capabilities into their production lines. By combining the key elements of serialisation – marking and verification – into the checkweigher, companies save both cost and space,’ said Kevin Zarnick, North America pharmaceutical sales manager at Thermo Fisher Scientific.

Thermo Fisher’s customisable approach to building a Versa RxV enables manufacturers to select which code printer and vision system brand is added to the checkweigher frame. The modular build means that pharma companies can specify the components they prefer.

According to Thermo Fisher, a key differentiator of the Versa RxV from competitive all-in-one units is its single operator interface. Instead of mounting separate user interfaces for the checkweigher, code printer and machine vision system, the firm has incorporated the control of all functions into one screen. This improves ease-of-operation and saves valuable line space.

To improve checkweighing accuracy, a single brushless motor is mounted in the back of the enclosed cabinet that minimises mechanical vibration while powering the infeed, weigh table and outfeed conveyors. The “knife-edge” belt design also provides superior product handling when products travel from the infeed conveyor onto the weigh table at high speeds.

Additionally, side belts with horizontal and vertical adjustment ensure the correct position of the bottle or carton during marking and verification.

The checkweigher also features two reject mechanisms – one for packages rejected by the vision system due to illegible or incorrect codes and the other for over/under weights.
