System Generalities
Mox lab presents the Crimping Compute Module, absolute novelty in the field of the control of crimping dimensions quality
This absolutely innovative system uses simultaneously both image processing techniques and continuous mechanical rotation of the can to sample on 360° a big number of measurements on each single can
Components of the highest technological level, such as special optics and illumination, high level cameras and compact processing units can guarantee incredible results
High-Quality Telecentric Optics
Rotating Unit with Can Protection Sliding Door
Interactive Real Time User Interface with Touch Screen
Principles of Operation
The system measures the can height and diameter acquiring big number of images during can rotation
Each acquired image, is processed according to sophisticated algorithms and height and diameters are continuously evaluated image by image
When the acquisition session is completed, the overall averages measures for both can height and diameter measures are evaluated and display
Motor controlled Rotation support
Optional vacuum system for best holding of the cans
Glass cover to ovoid any external ligh noise during caption
System Characteristics
When Starting a new acquisition, the
Touch Display show in real time the
results of each image processed. A
clear graphical Chart describe the
trends of the measurement algorithm
Each acquired image, is processed
according to sophisticated algorithms
and height and diameters are
continuously evaluated image by
image
When the acquisition session is completed, the overall averagesmeasures for both can height anddiameter measures are evaluatedand display
User Interface
developed for an
optimal user
experience
Intensive image
sampling in order
to have the most
stable measure
Final measure is
composed using all
the captured and
measured images
Measurement Logic
The applied logic of the measuring
algorithms are the same logic and rules
used by the classical ‘mechanical’
caliber.
On each image the height
corresponding to the 19 mm diameter
on the valve is evaluated using
automatic shape recognition and
sophisticated measuring procedure.
Each image provides two measure
related to the height values, one on
the left side and one on the right one,
and one measure for the diameter.
Images are
acquired at high
sampling speed
On each image left
and right heights
and diameter are
evaluated
Continous and
exhaustive
evaluation is done
on all the single
images
System Added Value
The developed system results in a
strong and stable measurement
system for the crimping process
control
The first advantage of using this
measurement solution id that each
measure is independent from the
human behavior and the repeatability
of the measuring process is
guarantee by the system itself
Furthermore, the measurement
procedure is quite fast and can be
done manually on a big number of
champions during the production
operations
Repeatability of the measures
Measures are
indipendent from
the operator’s skill
and ability
Measuring process
is quite fast and
can be done on big
set of champions
User Interface
All the captured and processed
images are displayed during
acquisition on the interactive User
interface
Operators can follow the system
measurement processing directly on
the main chart reporting all the
increasing session measurement
Some basics Real Time statistical
data are displayed directly under the
main chart, in order to better
understand the cans characteristics

information report
Deep in Details
All the acquired data are registered
on the system storage unit in order to
be used for production statistics and
Batch data archiving
Besides the basics statistical data, an
additional set of info are provided for
each can such as stem presence and
Inclination, Orthogonality of the valve
with respect to the can and
measurement set variance

Collectible data
The system is able to collect, from each single can processing, the following data:
- Valve crimping height
- Valve crimping Diameter
- Can Stem inclination
- Can and Valve orthogonality
- Measure set Standard Deviation and Variance
- Cp and CPK values of the whole session measurement
- Maximum and Minimum crimping quotes detected
- Can Crimping Fingerprint: trend of the measures variation on the can circumference. Give a clear idea about the quality of the crimping process on the single can
Technical info
The casing of the machine is made of
custom-shaped bi-color hot-painted
steel
The sliding door is made of thermo
formed plexiglass and allows to
protect the system form external light
interference during image caption
The system is equipped with both
Telecentric Optics and Lighting to
guarantee the best acquisition
