ABSTRACT: Problem bottling is a very cost-intensive part
of beer and liquids production. One problem is that the efficiency of
bottling plants isn’t high enough. To increase the efficiency of the
plant, operators need to know the critical points of their plant. In
addition they need to measure the influence of different parameters on
efficiency. For this, the LVT (Chair of Food Packaging Technology) of
TUM (Technische Universität München) and partners started the research
project LineMET, which was funded by the Federal Ministry of Education
and Research. LineMET should generate an efficiency analysis tool that
helps the operator to find critical points and influences of different
parameters automatically using operating data. Based on the research
presented at the 2007 MBAA Convention by A. Kather, LineMET had the
following goals: development of an integrated efficiency analysis tool
(demonstrator application); extension of the component library (LineMod)
for model base diagnosis; extension of the LineMod system boundary to
rate influences from logistics and intralogistics to the plant;
extension of the diagnosis functions to complex patterns; and
development of a tool to generate line models from the component library
methods. The project was divided in four parts. One was a database that
contains data points according to the Weihenstephan Standards. This
information is enough for key performance indicator (KPI) calculation
and line diagnosis. The most important part from a scientific point of
view was the model based diagnosis, where LineMod, the model library,
was extended. New components were built, like split and merge for
splitting/merging object flows. With this library nearly all kinds of
filling plants could be modeled. The extension of the models to analyze
minor speed of bottling plants was also a result. Another part was the
development of ATLAS. ATLAS is a graphic tool to build plant models.
Users only need to rebuild their line with drag and drop out of the
component library and to set some parameter, like death time of
conveyors. The last part is visualization. LineMET gives examples of how
to visualize the diagnostic results and to calculate article related
KPIs. It is important to investigate influences of bottle type or
product, for example on the efficiency of the whole plant. LineMET had
two big results. 1) Model based diagnosis can now be used for bottling
plants. The determination of reasons for filler downtime is now
possible, with a rate over 85%, and all types of bottling plants can be
modeled. 2) A demonstrator application was implemented in a commercial
tool. It calculates article related KPIs based on real plant data. The
only requirement is that the plant provides data according to the
Weihenstephan Standards.
Stefan Flad, born in 1982 in Freising,
received the university entrance diploma in 2002 at the Dom-Gymnasium
in Freising. After that he studied from 2003 until 2008 at the Technical
University of Munich, Garching. In 2008 he graduated as an engineer
(Dipl.-Ing.) for mechatronics and information techniques. Focus areas
were microtechnics and control engineering. In late 2008 he started as a
Ph.D. student at the Chair of Food Packaging Technology, Technical
University of Munich. He was project coordinator of the LineMET project.
He works on the member committee of the Weihenstephan Standards for
data acquisition and teaches process control engineering at TUM.
