Product Information    

Background In  today's  pharma  packaging  production  mostly  highly  flexible packaging centers are used in order to meet the demands of high yields. This  is  caused by  the  increase  in  variety of products and packaging  presentations  as  well  as  the  increased  numbers  of small‐sized and micro‐sized batches. Above all, these systems are geared  to  fast  changeover  times  and  easy  clean‐ability  during batch  changes  and  thus  to  effective  production  in  order  to produce with a high total OEE.   Conversely,  this means  that more  and more  different  products are being run on these packaging lines. Some are partly similar in appearance or even look the same. The traditional camera‐based product  inspection  alone  therefore  can  no  longer  reliably differentiate between all of them and there  is a potential risk of mix‐up.

 The development of VisioNIR AS is the result of the considerations described above. The outstanding feature of VisioNIR AS is its dual function  which  is  also  revealed  by  its  name:  Visio  stands  for traditional  optical  inspection,  NIR  stands  for  near‐infrared spectral analysis (AS meaning Area Scan).  NIR  is  particularly  interesting  for  spectral  comparisons  and,  in analogy  to  criminal  investigation,  it  can  be  referred  to  as “molecular fingerprint”.

Functional Principle   

 

  Highlights  

The  vision  system  takes  a  snapshot  of  the  format area  and  performs  its  optical  inspection  (color, geometry,  etc.)  using  a  high‐res  camera  and  LED illumination.  It  also  provides  the  coordinates  of each tablet to the NIR system. The NIR system has a separate  light source  (halogen) which provides NIR radiation. This radiation is bundled and transported via  an  illumination  fiber  through  a  galvo  mirror system, which targets each tablet with a  light spot. On  the  same  pathway  back,  the  reflected  NIR radiation with spectral  information  is  then coupled into  the  collimation  light  fiber. The  collimated NIR radiation  is  transported  to  the  diode  array  NIR spectrometer  and  converted  into  a  spectral  chart.Evaluation  is  performed  via  software  so  the information  of  these  spectral  charts  can  be classified  in  order  to  distinguish  tablets  based  on their  physical‐chemical  characteristics  resp.  their “forensic fingerprint”.
