5.1 Preparing the teach procedure
If you are using the CheckKon/CheckOpti software packages,
please note the instructions in the software manuals on how
to prepare the teach procedure.
As standard during the teach procedure, the parts are blown
down from the belt at the first blow-down position. This is to
ensure that no sample parts are unintentionaly transported
further to the next machine.
5.1.1 Features and characteristics of the conveyed parts
The Checkbox registers conveyed parts as two-dimensional,
black-white profile pictures (parts contour). Features for dis-
tinguishing different good parts are derived from the parts
contour. Discolouring and surface faults do not influence the
test result during this recognition process.
The features of the conveyed part, which determine orienta-
tion and quality and which are important for the distinguish-
ing process, must be recognizable to the Checkbox.
Provide suitable sample parts for every parts type in accord-
ance with the following specifications:
– The sample parts show all the characteristics which a part
classified as “good” should possess.
Use different sample parts with a usual scatter of fea-
tures. With the scatter of features, you can determine the
extent to which test parts later classified as “good” may
deviate from each other.
