Integration saves development time in the high-performance labeller

In 1932, master machine builder Albin Langguth founded the family-run Langguth company in Münster. The initial core business was based on repairs of all kinds for machines in the brewery, dairy, laundry, and filling machine sectors. However, the focus was always on the construction of new machines. Gradually, the company developed into a sovereign medium-sized enterprise and expanded as well into the USA and France.

The company now employs around 100 people and can look back on 90 years of experience and tradition. Today’s core business is based on the construction and development of labeling machines in the medium performance range, which are divided into the four different machine types “wetLAN”, “selfLAN”, “hotLAN” and “moduLAN”. Each range stands for a different labeling process, with the “hotLAN” category representing a process using hot glue.

Thanks to the cooperation with Siemens, it was possible to develop an intelligent solution for this process and to implement the high-speed “hotLAN 378” machine. Thanks to the use of a SIMATIC S7-1515T controller, several SINAMICS S210 servo drives and the TIA portal, a complete solution with servo drives instead of mechanical systems could be created. The integration of motion control and safety technology into the controller makes programming and commissioning a breeze.

The spin spray process allows cycle rates of up to 60,000 containers per hour with minimal glue consumption. This system is used mainly for labeling round containers. Another important point is the high efficiency of the equipment, which is achieved by non-stop operation and minimal changeover times.

“By using Siemens components, we save on training and engineering costs, which we can pass on directly to our customers. They also benefit from reduced maintenance costs and worldwide availability of spare parts,” says Franz-Josef Gehling, Product Manager in the hotLAN division of Langguth GmbH.

Langguth also relies on Siemens technology in other areas of the company, thanks in part to the high level of customer satisfaction and the very good technical support.

Further plants are already being planned for the future. The focus here will be primarily on the point of sustainability, as this is an extremely important topic for the Langguth company.
