Safety Solutions for Air preparation

Customer: NPB Automation, Jönköping Sweden

Manufacture of beverage cans and tin cans is a niche part of the packaging industry which has seen a steady growth for a long time. NPB specialize in automation with extremely high efficiency. It constructs a handful of special machines – wrapper, dewrapper, bagger, debagger, balancer, palletizer – all customized per client’s requirements.  Through the years, NPB tried several security solutions for air preparation. But despite the indications from the safety valve, it has proved to be air in the system. The constructions have simply been so complicated that they have not worked satisfactorily together with the PLC system. Instead it has become directly unreliable. The solution from SMC is based on two emergency stop independent of each other. The safety valve has no built-in electronic logic circuit. It lacks intelligence and sends signals only to the secondary side is guaranteed without pressure at a given position, which eliminates the risk of unexpected movement of the machine. Thanks to the simplicity no hassle associated with customer safety PLC is raised. With SMC’s solution NPB has achieved a high but appropriate level of security that meets the security requirements and at the same time it is economically advantageous.  SMC has since delivered several varieties of the solution that is now installed on all machines at NPB.

“Nothing is more important than the safety of a machine! People should not have to risk being injured on the job. For a long time we have tried various security solutions of a high standard but the complexity has only led to a lot of hassle. SMC’s solution spot in its simplicity and yet so thought out. Magnus Wigenstedt, Export sales and marketing NPB Automation
