5.1 Preparing the teach procedure
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.
Features and characteristics of the conveyed parts
– The Checkbox must be able to recognize those features of
the conveyed part which determine orientation and qual-
ity and which are important for the distinguishing pro-
cess.
– Small rotationally symmetric parts are particularly suit-
able. Non-rotationally symmetric parts can however also
be checked if a pre-orientation of the conveyed parts is
made with the small parts conveyor.
– The conveyed part must be positioned reliably on the
conveyor belt.
– The length, diameter and height of a conveyed part
must be suitable for the Checkbox.
– The conveyed part must be positioned in a stable
orientation on the conveyor belt (it must not roll away
or vibrate).
– The conveyed part must be sorted out reliably by the
actuators. Check during a test run to see if the actuators
used (e.g. blow nozzles) can sort out especially large con-
veyed parts made of material with streamline form.
