Inner Sidewall Inspection Excessive False Rejects
1. If production operation allows turning all ISW rejection OFF, do so
using the
CONTROL > ISW
screen and disable the
REJECT
ENABLE
function. (Set to 0.)
2. If it is not possible to turn all ISW rejection OFF, disable the
REJECT STATUS
of the individual regions which appear to be a
problem.
3. Verify the inspection zones are concentric with the bottle bottom
image. If they are not, go to the
INSPECTION SETUP > ISW
screen and adjust the horizontal and vertical settings as required.
4. Check the
Current Detects
column to see if any of the inspection
zone is detecting more often than other zones.
5. Use the button with the bottle (under the image) to "freeze" the
rejected bottles and examine their images.
6. Observe that the frozen reject bottle image will have small red dots
marking the places where it located the objects. These dots are called
detection points
.
7. Observe the
DETECT
function. This is normally adjusted to a value
between 100 and 200. The higher the number, the more sensitive the
inspection zone will become. The highest possible value is 999 and
lowest is 1.
