Object diameter measurement
Task:
In a Bearing manufacturing plant it
happens that balls of incorrect sizing
fall into the mix. The customer wants
do differentiate between one to two
sizes as some bearings use two differ‐
ent sizes. The application is very fast
and an accuracy of 0.5mm needs to be
detected.
How to ... (Setup and configuration)
Using the AS30, we can set two fields. One field would be the correct ball and the sec‐
ond for the second size. If only one is needed, only configure one.
The measurement value can also be monitored using the analogue output or IO-Link for
more variables. With IO-Link, you can have four pre-configured sizes.
•
Run an easy teach to evaluate the
first result
•
Run an advanced teach and based
on the reflectivity of the ball, select
your sensitivity. In our case “Fine”
was suitable
•
In the Configuration Qint, set your
tolerance values in window mode
and output to QL1
•
For Qint 2, set your broader detec‐
tion window if a second size is
needed and set the output to QL2
Sopas
First steps
1.
Using a set background ( conveyor or slide), do a standard setup of the device. Use
a single teach (Image 1) for each of your sizes to establish the sizing based on the
mounted distance.
2.
Set your window to an acceptable tolerance (Image 2).
3.
Re-evaluate your sensitivity and teach-in tolerance to the most robust detection.
