Automation System PSS 4000 from Pilz Automation Safety, L.P.

These days the quality of the packaging is as important as the packaging lines being multifunctional. Not only must the lines satisfy the very highest requirements in terms of productivity, flexibility and reliability, but safety must also be absolute.

Quality and efficiency - Modernized safety technology

Nestlé Purina Petcare, based in Aubigny, France, is a worldwide manufacturer of dog and cat food; it's priority is the quality of its products. to guarantee this quality into the future, the company, which belongs to Nestlé France, arranged a comprehensive retrofit of its production facilities. The focus was on modernization of the electronics and the safety of the packaging lines. The aim was to increase production to serve the rapidly growing market segments for the Nestlé products manufactured in Aubigny.

PSS 4000 for highly flexible packaging processes

To manufacture and package high-quality pet food, packaging lines need to be flexible and must meet today's applicable safety standards. At Nestlé Purina Petcare, products are generally packed into rectangular aluminum pouches. The package designs vary, depending on the type and size of the package to be filled. As there are repeated changes in the packaging process, the engineering needs to be flexible. in this case the automation system PSS 4000 was the perfect fit to do the job.

Data is transmitted in real-time via Ethernet

Other criteria for using the automation system included easy operation and diagnostics via the corresponding software platform PAS 4000. Data transfer via the real-time Ethernet SafetyNET p, which enables all data to be transferred safely, was another key factor: The real-time Ethernet adapts to the existing data transfer structure and uses the existing Ethernet (Modbus TCP) to communicate with the distributed remote stations PSSuniversal I/O and the automation system's higher level control systems PSSuniversal PLC. Safety data from the individual stations is transmitted to the installed operator terminals in real-time along with the data from the packing stations.

Overall packaging line process assured in the event of partial failure

The PSS 4000 also enables all data to be managed on a decentralized basis: if any of the seven areas on a packaging line has to switch to a safe condition in the case of danger, the other areas will continue production, so that the overall process is not interrupted.

"We were able to reduce downtimes significantly thanks to the improved diagnostic function." Thierry Jouval, Project Manager at Nestlé Purina Petcare

TUV Rheinland Robot Integrator Program

TUV Rheinland Robot Integrator Program

The industry's first comprehensive Robot Integrator Program saves robot integrators significant time and cost investments by allowing them to mark each cell compliant with ANSI/RIA R15.06 with the TUV Rheinland Mark. As opposed to a traditional certification or an on-site field labeling, TÜV Rheinland's Robot Integrator Program certifies the knowledge and skill-set of robot integrators in addition to testing robotic cells and processes against ANSI/RIA R15.06. This reduces the need for frequent onsite or off site testing and allows manufacturers to apply a single TÜV Rheinland label to multiple cells. The Robot Integrator Program individually assesses a robot integrator's understanding of the ANSI/RIA R15.06 standard along with the ability to consistently produce compliant robot cells. Following the requirements and procedures of the new program will enable robot integrators to produce individually compliant robotic cells under one serialized TÜV Rheinland Mark, which meets the national electric code and allows acceptance by Authorities Having Jurisdiction (AHJ) and end users.
