With system integration toward the Internet of things
RFID readers in the dye house read the contents of radio tags, robotic dispensing systems supply the precisely constituted dye mix. If sensors report excessive shrinkage of the textile goods, the smart machine controller corrects the process parameters.

If delivery deadlines are not met, downstream production processes are adjusted immediately. For Andreas Hannes, Marketing Manager with Sedo Treepoint GmbH, the company has been on course for Industry 4.0 for a long time. Based in Mengerskirchen, Hesse, Sedo Treepoint GmbH specialises in digitising and automating the manufacturing processes for textile finishing. As a member of the VDMA, it is listed in both the textile machinery and software divisions. In an interview with Andreas Hannes.
How do you set about creating a digital network for the purposes of Industry 4.0, and how does this affect the human operators?
In the case of the new textile finishing facility for the Shandong Ruyi Group, one of the largest textile manufacturers in China, in 2014 we carried out a total digitisation project. In terms of data integration, the project involved networking all continuous machines, production data acquisition, an energy management system, the enterprise resource planning (ERP) system, and even printing management as well as other elements.
We keep ourselves very closely informed about new trends like the Internet of Things and include them in our developments. This removes much of the burden from human operators. The installed central system is self-explanatory and easy to operate. All information can be accessed at the workstation; machines can be operated and controlled from the work desk. Machine parameters are fine-tuned and production is planned by the system. Maintenance and diagnosis can also be carried out remotely. Consequently, human operators are more mobile and their role becomes one of supervision rather than hands-on intervention.
You describe yourselves as trendsetters for IT in textile finishing. Could you explain what this means specifically?
Sedo Treepoint earned its reputation as a manufacturer of machine controllers in the form of touchscreen PCs and in hardware automation. This includes the software that runs on the machines. And the importance of the software is growing. Dyeing machines were automated for the first time anywhere in the world 30 years ago in Mengerskirchen. Since then, we have developed many integrated systems; after all, the technology has not ceased its advance. Today, our company offers integrated software and automation solutions for all textile finishing applications, and for other departments too. If a production facility is responsible for multiple processing stages, for example spinning, knitting and weaving, we can offer products for these areas as well.
Sedo was one of the first companies in the world to carry out integration ? that is what we call the networking of data from various systems ? of colorimetry in the laboratory and in production. One milestone was an additional software package for energy management, which we introduced onto the market four years ago, at the last ITMA. There are no products like them in the textile industry with such versatility. The customer can effectively create his "own" product from the Sedo module system and expand it one step at a time. In the case of a completely new investment, we can carry out a deep integration with all systems, functions and departments.
How is this integration organised?
Vertically, let’s start at the top of the automation pyramid, for example. The apex is the ERP system, in which the orders are entered or invoices are written. The orders then pass right through to the machine level at the bottom. Of course, machines are not
