In October, Zwick invited Roell to the testXpo again - and held a press conference as part of the in-house exhibition. Among other things, the new testing machine generation Allround-Line was presented. This is a flexible system with two test rooms that can be used for testing tasks in quality control as well as in research projects.
A new manufacturing cell that includes milling, loading, and unloading, plus clamping technology and sensors for improved reliability facilitates the production of worm gear screw jacks considerably.
An industrial wafer baking machine is complex in terms of control technology. The ignition process of the gas-fired long-tube burner alone comprises 20 individual steps. Numerous other process steps are added as the baking process continues. The wafer machine specialist Franz Haas-Waffelmaschine therefore decided in favor of a flexibly configurable, safe miniature control system that can be used to monitor and control not only the functional safety but also the burner control and thus the entire safety technology of the baking machines.
Large batches are increasingly being replaced by short runs – and this also applies to labels. To keep changeover times and waste low, the Danish press manufacturer Nilpeter relies on a vision system that is fully integrated into the line.
The system allows monitoring of the process stability involved in laser structuring for the design of a new range of functionalized surfaces such as easy to clean finishes for ovens, fridges, and other home appliances.
The presentation of the inspect award 2022 took place at the Vision trade fair - on a smaller scale than usual, but still with overwhelming glamour compared to the Lockdown 2020. Awards were presented for the best innovations in industrial machine vision and optical metrology. Thus, the journey to Stuttgart was worthwhile for the attendees not only because of the Vision.
For the first time in three years, the machine vision industry made its pilgrimage back to Stuttgart for Vision. It all took place on a smaller scale - fewer exhibitors and visitors than in 2018 - but the joy in view of the reunion outshone everything.
Technical article by Lea Sauerwein, Christian Ebenhöh, and René Geiger in the current issue 5/2021 of PhotonicsViews: a new approach to the joining of polymers combines two different processing wavelengths with the method of quasi-simultaneous welding in order to achieve a significant reduction of welding time and enhanced weld seam quality.

Instead of printing the barcode on the packaging, it can also be lasered directly onto the skin of fruit or vegetables. This saves on packaging costs and protects the environment. But to ensure that the peel is not damaged in the process, the focus of the laser must be precise, despite the fact that the individual fruits are always different sizes. A 3D sensor from a company in northern Germany helps with this.
Collaborative robots (cobots) have a key role in current and future trends in industrial automation and production.
