Quality inspection machine for PET-Recycle
Small samples from the PET recycle material are collected during
production.
4 kg Flakes material out of 5000 kg is used to make sample
disks.
This samples are inspected with a camera. Black Specks are classified. into 3
to 4 classes. The number of specks and the class size are
counted. If the percentage of disk with Specks pass the
Specification, then the Production-lot is free to be used for
Preform. This process reflects the purity of produced flakes material astonishing well.
Machine with:
- Sample feeder
- Camera Inspection
- Colour spectrum measurement
- Defect Disk rejection

Disc Inspection IS10: Quality Inspection
Machine for recycling or vergin PET
The quality of the recycling material is
measured with counting the specks, classifiing them in classes
and checking as well for clouds coming from dirt. Additional
classes of very small Specks give a feedback about the quality
of the production. The good function of Windshifters to remove
lable or wood parts or of the Metall detectors are visible
quickly after inspection.
Beside of Black Speck inspection the
machine can be equipped witha color.
Spektrometer. We have combined automation computer (PLC) which
controlls the disc supply, To Camera and Spectrometer and
Evaluation to a fully automatic inspection. The machine
with Spectrometer (Konica Minolta
spectrophotometer) is able to test the color of hundreds (or thousands)
of samples fast.
Our
system transfers a sample (plastic) to the
spectrophotometer, than instructs the spectrophotometer to take
a color measurement, than transfers out the sample and transfers
the next sample. The system is able to reject the color-faulted
samples and collect the good ones.

Color Measurement
At
the color measurement you can specify a reference color and a
tolerance radius. If the sample is little bit different from the
reference color, but the difference is within the tolerance,
then the sample will be accepted; otherwise it will be refused
and even mechanically rejected to a separated container. If you
are interested about the cloudiness of the samples, you also can
specify a reference

value, and an upper or lower tolerance limit (or both). So, if
the sample is too much cloudy comparing to the reference value,
it will be refused and rejected. On the same way, if the sample
is too less cloudy comparing to the reference value, it is
refused and rejected. You can specify the acceptable difference
with the upper and lower tolerance limit.
