Pilz offers TÜV-SÜD-certified solution for safe monitoring of cardboard feed in the packaging sector

With the TÜV-SÜD-certified safety solution, which safely monitors the cardboard feed on packaging machines, this process can now be designed to be safe and productive. The solution package offers two safety controllers to choose from — the small controller PNOZmulti 2 for applications configured via a software tool, and the safety relay myPNOZ for batch size 1 infeed solutions. Two optical sensors are added per infeed device. The solution complies with performance level (PL) d and category (Cat.) 3 of EN ISO 13849-1 or SIL 2 of IEC 62061 and ensures minimised downtimes and higher productivity for greater efficiency in the secondary packaging sector.

The new, certified safety solution from Pilz monitors small and medium-sized machines in the secondary packaging sector. Certification saves users time during design, configuration and commissioning. With the TÜV-SÜD-certified safety solution, even integration into existing applications and retrofitting is easily implemented. As a result, the application can be adapted flexibly and individually at any time. Also, there is no need for additional protective measures such as safety fences or similar guards, so the space can be used more efficiently

Specific application depends on use

For machines with a small function range, the package includes the modular safety relays myPNOZ: the tailormade batch size 1 solution can be used immediately via plug & play and is available as a pre-configured unit. The small controller PNOZmulti 2 is used for more large-scale projects. With this, safe automation projects can be implemented flexibly via a graphical configuration software tool. What’s more, if necessary, two cardboard magazines can be monitored simultaneously with just one base unit.

Both safety controllers monitor the optical sensors — installed directly on the infeed opening — which register the status of the cardboard boxes. Additional safety functions such as E-STOP, safety gates or light curtains can also be implemented.
