Oerlikon Manmade Fibers Segment
En route to the digital yarn factory

“From Melt to Yarn, Fibers and Nonwovens – Bring it to Life” This is the motto under which the Oerlikon Manmade Fibers Segment will transform itself into a digital machinery and plant manufacturing company for the production of chemical fibers.

 En route to the digital yarn factory, technologies such as artificial intelligence, machine learning or innovative HMI (Human Machine Interface) solutions promise the bridging between material and data flow – for customer value. These topics are also the central point of the “Oerlikon Innovation Forum” at which presentations in English and Chinese will be held several times a day for visitors of the exhibition booth.

The scenario of the future: textile production – from the supply chain through to dispatch – is autonomously controlled in the fully-networked Factory 4.0. The product being created controls and monitors the processes itself using embedded sensors. The manufacturing or order status is known at all times, raw materials are automatically reordered, wear and maintenance are planned as integral parts of the production process and error processes are identified, alleviated or displayed. This should cut costs, convert production lines more flexibly and help reduce downtimes and waste. For this, the machine construction sector has to provide correspondingly intelligent and web-enabled production systems. No easy feat, as this requires interfaces between all systems involved and the collation, channeling and evaluation of tremendous volumes of data in real time.

Oerlikon Manmade Fibers Segment wants to face these technical development challenges and has high standards. “We want to become the textile machine construction trendsetter for technologies of this kind,“ says CEO Georg Stausberg. The first steps on this journey have already been taken. The Plant Operation Center (POC) for process monitoring enables the collation of existing production data in a central location and to make these data available. HMI based services such as process monitoring via a service online app on smart phones and tablets were introduced as well as an assistance system based on mixed-reality glasses (Microsoft HoloLens). The system supports predictive maintenance concepts and enables virtual 360-degree tours through spinning systems.

AIM4DTY: Automated detection of error cause

At ITMA Asia + CITME 2018 the company gives an insight to this as well as an outlook for new developments for the digitization of the process chain “From Melt to Yarn, Fibers and Nonwoven”.

The digital future solution AIM4DTY provides help with the identification of possible error causes in texturing machines to help reduce quality risks. Here, machine learning is being used: The system recognizes and is being “trained” using trend charts and their respective errors. For example, in the texturing machine, the UNITENS monitoring sensor continually measures the yarn tension at all positions. An error is generated if a measurement value does not lie within the prescribed tolerances. In a lot of cases, the form of the graphs can provide information on the error causes and ultimately provide targeted and efficient response to these. A manual analysis and optimization is nearly impossible with more than 125,000 graphs per day. With the automated solution AIM4DTY the information is instantly available to customers, therefore allowing them to immediately optimize the quality during running production. It also ensures that predictive maintenance is now a reality.

Here, data security, data minimization and transparency are extremely important. This means that the data are utilized at the customer site as far as possible and only transferred to the Oerlikon central customer data center if required – and only following customer approval. “We process all data in accordance with the new European General Data Protection Regulation (GDPR), taking all further international data protection standards into account. Our customers always know which data we use and why”, explains Mario Arcidiacono, Business Intelligence & Data Warehouse specialist for the Oerlikon Manmade Fibers Segment.

Wiping robot with intelligent control system

The crucial advantage of the wiping robot used for the cleaning of the spinnerets is automation: intelligent control system which connects machines and processes. The information relating to all wiping positions, cycles and times can be saved in the management system. The robot accesses the saved wiping intervals in an automated and safety-relevant manner. To this end, the robot can cope with up to 48 positions, corresponding to one entire production line. However, the more decisive here is the impact of the intelligent control system, with whose help the spinning pump can be moved up and down in an automated and ‘in-time’ manner. To this end, pump stops can be kept to the absolute minimum using a robot, considerably reducing the impact of the wiping on both the polycondensation system process stability and on the yarn data of the spun yarn. The advantages over the manual process are for example extended cleaning cycles, less silicon use, more production time, less operating costs as well as advantages for human resources and health management. The wiping robot has been operating at two major yarn manufacturers in China now.

Staple FORCE S1100

The Staple FORCE S1100 is a one-step plant, which spins, draws, crimps, cuts and bales in a single process step, produces small batches (up to 15 tons per day) and can be swiftly reconfigured for various requirements, including polymer, dye and titer changes. Its process control system for easy operation is absolutely unique.

The service for repair-coating from Oerlikon Barmag for thread-handling parts such as godet jackets also includes the expert’s know-how to identify and review abrasion in order to recreate the correct surface structure at the location. This way they can provide all important requirements to creating optimal plant and yarn quality.

News from the PA6/66 sector

With the acquisition of the PE Polymer Engineering Plant Construction GmbH, based in Thuringia, Germany, Oerlikon Manmade Fibers Segment expanded its now completed polyamide process chain for fibers and filaments. The now available and tested technologies in the melt preparation process include the entire polyamide 6 polycondensation systems division and its PA6/66 co-polymer and the patented dimer-hydrolysis procedures for feeding recycled-lactam with the very highest end-product quality.

En route to digitization with a new mindset

To show its direction towards digitization, the company wants to offer virtual experiences to its visitors alongside machine exhibits at the exhibition booth in hall 2, B24. They will be deploying playful solutions to present the topic of artificial intelligence as well as a virtual showroom to allow visitors to experience complex systems live in 3D. “We want to show that the ‘digital factory’ is already in part becoming a reality in conjunction with our machine exhibits and that we are in a good position to further optimize the efficiency of our equipment and quality of their end products – with digital solutions” affirms Georg Stausberg.

According to the CEO, Oerlikon Manmade Fibers Segment already started establishing new ideas and mindsets a few years ago, and are working between disciplines, departments, areas and companies.

An important step was the acquisition of the newly integrated partner AC-Automation who has substantiated know-how in large-scale automation, transport, packaging and warehouse logistics and end product automated quality control. “Together with our process competencies and digital data handling we not only want but will offer further innovative Industrie 4.0 solutions for our customers – all the way to the digitization of the complete process chain,” promises Georg Stausberg, Segment CEO Manmade Fibers.
