The German company Wohlenberg Buchbindesysteme (Wohlenberg Bookbinding Systems) is using Pepperl+Fuchs’ vision sensors in collating machines and adhesive binders to detect incorrect sheets.
The sensor’s camera, lighting and processing unit is integrated into a complete compact system, which does not need any external processing unit. Barcode and image comparison evaluation methods are contained in one device, significantly reducing integration time and costs.
With a maximum sheet speed of 6 m/s and a cycle time below 80 ms, the vision sensor is ideal for high processing speeds, and still has free resources for faster processes in the future! Functionality is further enhanced with the integrated rotary encoder interface for simultaneous offset of the trigger point. An error image memory stores image results and allows the simulation of false detections. This memory supports the customer during setup and when analyzing problems. In normal operation mode, the fast image transfer enables a visual check and image verification.
Pepperl+Fuchs provided a very viable solution for Wohlenberg Bookbinding Systems. Wohlenberg noted a primary reason for selecting the vision sensor was its long-term availability, since the sensor is produced entirely by Pepperl+Fuchs.
