4.1 Preparing the Teach procedure
If you are using the CheckKon/CheckOpti software package:
note also the instructions on preparing the Teach procedure
in the software manuals.
Features and properties of the conveyed parts
The Checkbox registers conveyed parts as 2-dimensional,
black and white profile pictures (parts contour). Features for
distinguishing various good parts are derived from the parts
contour . Discolouring or surface faults do not influence the
test result in this recognition procedure.
The features of the conveyed part relevant for distinguishing,
as well as for determining the orientation and quality, must
be recognizable for the Checkbox:
S Use the Checkbox preferably for testing rotation-symmet-
rical small parts.
The testing of non-rotation-symmetrical parts is only pos-
sible if a pre-orientation of the conveyed parts is carried
out with the small parts conveyor.
The conveyed part must be fed through in a safe manner on
the conveyor device:
– The length, diameter and height of a conveyed part must
be suitable for the CHB-C-X.
– The conveyed part must be supplied in a stable orienta-
tion (it must not roll away or vibrate).

actuators.
As standard during the Teach procedure, the parts are sorted
out at the first actuator position. This is to ensure that no
sample parts are transported by mistake to the next machine
in the process.
