Securing Beverage Capping Systems
Manufacturing News Center
Abstract-- ELAU’s new integral servo motor/drive, the PacDrive™
SCL-055, has received significant attention among respected liquid packaging
machinery builders.
Already, KRONES, SIG Alfa, SACMI Labelling, SIG Simonazzi, IMA, Ronchi
Mario and Alcoa are applying the purpose-built SCL servo technology.
Discussions with many other European and North American machine builders
are also underway.
There are compelling reasons for using the PacDrive SCL in all liquid
packaging applications, from beverages to pharmaceuticals to liquid
foods. In the beverage sector, Krones AG, which introduced their new
servo capper using the SCL technology at the Brau Beviale 2003 trade
show in Nuremberg, cite these main benefits:
- Pushbutton recipe changes Package format changes -- caps or bottles
-- can be selected at the operator panel and implemented without manual
adjustment of the capping heads.
The new Krones Servo Capper was introduced
at the Brau Beviale 2003 trade show in Nuremberg, using a new
PacDrive SCL-055 servo motor/drive-equipped automation system
from ELAU. |

- Capping process quality
The quality of the capping process is directly dependent upon the consistency
of capping torque. The precise servo feedback ensures the accuracy of
the capping moment to within + 1.5 lb-in. The beverage industry measures
capping torque specifications according to the Cpk processability index,
with a minimum Cpk target of >1.33. This value was very difficult to
reach with a mechanical capper, while the new servo capper exceeds this
value by a significant margin.
- Error detection and quality documentation
The controller detects faulty or slipping threads and misaligned or
deformed caps and assures that faulty units are ejected from production.
In addition, electronic capping heads permit the online documentation
of quality parameters. Statistical data can then be accessed and analyzed
by production management systems.
- Predictive maintenance
Remote diagnostic capabilities in the PacDrive system enable preventive
maintenance to reduce unscheduled downtime. Increasing bearing friction
in the capping head or in the motor, for example, can be sensed, the
cause identified, and the appropriate maintenance interval predicted
before failure occurs..
- Optimized for liquid applications / rotary tables
The SCL servo motor/drive’s trapezoidal form factor lends itself to
integration on space-restricted rotary tables. Integrated electronics
eliminate the need for separate amplifiers and electrical cabinets on
the rotating machine member. Wiring requirements are vastly simplified,
with a single cable connection between motor/drives and a carousel-mounted
power distribution box. The SCL features IP 67 moisture sealing and
a durable, multifunctional coating makes the PacDrive™ SCL-055 resistant
to caustic chemicals.

One PacDrive
controller can handle up to 99 SCL servo motor/drives. A single cable
provides the PacDrive SCL with power, motion control interface and
I/O communications. |
