BMS controller.
cessary if something is jammed,
for example, or if a bottle is lying
the wrong way in the crate. After
this, the crates are transported
to the decapping unit, then to
the bottle check. “An identification
system checks the crates to
see which ones contain standard
NRW bottles, which we process,
and which crates contain
other bottles,” explains the head
of operating technology.
A Unipack 103 sorting and
unloading machine from BMS,
which has individually controllable
gripping heads, reliably sorts
out the NRW bottles. All other
bottle types are placed on a separate
belt, where they are manually
packed into crates and transported
to an exchange store. The
empty crates travel to the crate
washing system, where they are
cleaned, and they are then transported
to the bottle packaging
machine and put back into circulation.
Bottle cleaning and inspection
The empty NRW bottles are conveyed
to the Lavatec E2 bottle
cleaning machine. In addition
to boasting high throughput,
this machine is effi cient when
it comes to the resources
of gas and fresh water. The
MOVIGEAR ® performance drive
units that drive the input and
output belts with the bottles
also provide greater energy efficiency.
After cleaning, the empty
bottles pass through the empty
bottle inspection machine. Using
a camera system, complete with
infrared and ultrasound technology,
this machine checks
whether there is any liquid left
in the bottles, whether they are
dirty or cracked, and whether
the mouth of the bottle is OK –
in other words, everything that
can currently be checked using
technology.
Filling, capping, labeling,
and packing
The inspected bottles are then
transported on conveyor belts
for filling. A Krones bottle filling
carousel first evacuates the
bottles and then rinses them
with CO 2
. To prevent oxygen deposits
and to balance the pressure
from the drink, they are
evacuated and rinsed a second
time. The beer bottles are filled
to overflowing and then capped
immediately. The fill level is then
checked, before the bottles are
rinsed off externally and labeled.
Finally, a BMS Unipack 2.0 gantry
machine packs the bottles into
crates that are then transported
to the warehouse for palletizing.
This is where the two BMS Unipal
105 palletizers come back into
play, this time to palletize the
beer crates, closing the circle of
the material flow.
Fig. 3: Standard asynchronous motors (left in the image) are used for angled conveyor
lines that require a brake. The energy for these motors comes from MOVIMOT ®
flexible inverters mounted close to the motor. The particularly energy-efficient
MOVIGEAR ® performance drive units (right) are only used for horizontal conveyor
lines. They feed kinetic energy back completely, and therefore need no brake.
Horizontal and angled
conveyor lines
“The customer wanted to use
energy-efficient,
decentralized
drives at the various conveyor
lines for the crates and bottles,”
explains the account manager.
“This is precisely what the
MOVIGEAR ® performance drive
units from the MOVI-C ® modular
automation system are designed
for. They are certified as energy
efficiency class IE5 and can be
controlled via PROFINET, which
was another thing the customer
had asked for.” The MOVIGEAR ®
performance drive units are used
for horizontal conveyor lines,
and therefore require no brake.
Standard asynchronous motors
are used for angled conveyor
lines that require a brake. The energy
for these motors comes from
MOVIMOT ® flexible inverters from
the MOVI-C ® modular automation
system that are mounted close to
the motor. Thanks to horizontal
compatibility across all electronic
products, the full range of motor
types can be controlled with just a
single inverter type, and only one
piece of engineering software is
needed.
Good communication
between the holy mountain
and Kirchheim
“This project was the first system
with MOVIGEAR ® performance and
integrated drive electronics that
SEW-EURODRIVE had designed for
a brewery customer, and the first
to be installed in Germany,” the account
manager recalls. The head
of opera ting technology adds:
“We enjoyed good communication
with Kirchheim, and always trusted
in SEW-EURODRIVE. What's
more, we really appreciated how
open and honest SEW-EURODRIVE
was with us.”
