The manufacture of snack products requires a multi-part, interlinked production cycle. Previously the plant sections were regarded as individual units with separate emergency shutdown circuits. That made troubleshooting time-intensive and meant a large part of production was stopped.Pilz developed a concept to optimise these processes. Now that the configurable small controller PNOZmulti 2 is used, …
When designing its machines it’s important to Marelec to offer maximum safety. The razor-sharp blades on the portion cutters represent the greatest risk; they are barely visible due to the fast cutting movement. That’s why Pilz advised the machine builder to use a protective cover including safety fence monitoring. If the cover is opened, the non-contact, …
Malfunctions can arise quickly if points are set incorrectly. So it was all the more important to the operators of the Dolderbahn and Rigi Bahnen AG that the points controller be upgraded to the state of the art and comply with the applicable CENELEC standards. There are eight points in total, made up of three …
The camera is mounted on a slide, which crosses access to the understage area at high speed downstage. Previously, flashing lights had warned of the approaching slide camera. The idea was to optimise this concept, to increase the safety of the stage technicians and exclude manipulation. Today, the danger zone is secured by Pilz’s Type …
However, the safety measures were not to hinder the (bending) process. Cost-optimised, integrated bending angle measurement on the camera-based protection and measurement system PSENvip from Pilz supports this aim – particularly on shorter length press brakes. The module that has now been integrated for bending angle measurement requires no additional space in the work area …
In principle the sensor detects when the danger zone is accessed and initiates a safe state on the machine. In this case, however, the sensor’s task is different: to monitor the area in front of the machine and ensure that the operator does not leave it. It is absolutely essential to monitor the deep drawing …
Three safety functions were to be reproduced on the inline measurement system– emergency stop, a safety gate required for setup and maintenance work, and a safety flap to prevent intervention in the upstream machine. In safety technology terms the safety solution also had to harmonise with the upstream and downstream production process. The safety solution …
PNOZmulti 2 carries out functional safety and burner control tasks as a complete solution in a single system; these are tasks that were previously performed by separate burner controllers. That’s quite a challenge, as monitoring involves a complex control sequence: At the heart of every wafer production line is the oven, which may be up …
The risk analysis from Pilz showed that appropriate protective measures needed to be taken on the assembly cell for the two intervention areas as well as the five maintenance flaps. As the required safety solution was to be flexible, modular and expandable for use on similar plants, the decision went in favour of the configurable …
From the storeroom, several tonnes of paper reels travel across the production plant’s operating area because, due to lack of space, the plant is built “back to front”. That’s why each reel must be inserted manually by an operator, with a considerable loss of efficiency. Also, for reasons of infrastructure, the plant had been reset …
