The Cotton Sorter comes with a touch screen based
operator’s console, allowing comfortable and easy
machine set-up, operation and follow up.
Contaminants to be ejected are described as a devia-
tion in color and size. The contaminant size is defined
as a combination of contaminant width (number
of pixels) and contaminant length (number of scan
lines). Tolerances in color are defined by means of
threshold levels (limits). Setting a low level results
in objects with a color value below this limit being
identified as a contaminant.
The result of the scanning by the cameras is shown
on the “camera display menu”. On the horizontal
X-axis, the number of camera pixels is indicated
whereas the Y-axis displays the color level. A value
of zero corresponds with black, whereas 255 means
white. It is obvious that the flow of normal cotton is
recognized as close to the white level.
Benefits
- Upgrade possibilities for low quality cotton
bales
- Evaluation of cotton suppliers
- Less customer complaints
- Independent of operator’s goodwill
- Higher efficiency on OE machines and winders
because of a lower number of foreign fiber cuts
by the yarn clearers
- Low cost of installation due to flexible system
set-up
- Low energy consumption
- No moving parts resulting in mini-mized main-
tenance
- Easy calibration, once a week (10 seconds with
stopped cotton flow)
