Colour Inspection

SPECTRA CL

The SPECTRA CL optical colour blister inspection is used to detect under-mixing, size, position, fragments and overfilling of products on packaging machines. It is the ideal solution for standard inspection tasks in colour. Correctness of the different colours by means of RGB values is displayed in real time – making safety in the packaging process child’s play.

  • Hard and soft gelatine capsules

Examination criteria:

  • Colour
  • Presence
  • Size
  • Shape
  • Circumference
  • Position
  • Fragments
  • Overfilling
  • Surface defects
  • Serial defects

Advantages of scanware colour recognition

Due to the use of the real-time operating system QNX®, the SPECTRA CL colour inspection offers outstanding speed and reliability. All parameters in the colour detection can be applied simultaneously – without loss of function.

The comprehensive analysis options, user-friendly software that can be tailored to your needs and the automatic learning run make it particularly easy to use. In addition, the system can be upgraded at any time to high-resolution SPECTRA HR blister inspection to reliably detect not only correct colour but also the most demanding product-film combinations, for example hormone products

Software facts of colour detection

The result on the line is something to be proud of – production and format documentation as well as analysis of lane and cup filling offer you unique opportunities to detect errors in the infeed and reduce ejection. This is made possible by visualisation on the software interface.

The image memory works with up to 50 images, based on which an individual system suggestion for parameter limits is automatically created. This offers greater safety and simpler operation than standard limits to be adjusted by the user.

The automatic learning run enables a fast transition to production, as object position, blister geometry and product colour are automatically recognised. Of course, a manual learning run is also possible.

Automatic mask tracking compensates for trigger differences on intermittent machines.

The comprehensive audit trail and global parameter limits for extra high safety are fully 21 CFR Part 11 compliant.

The electronic illumination regulation is set in 16 illumination levels by means of a simple measuring line. This allows the optimum contrast to be achieved for inspection of colour values; the format-related settings allow high flexibility on the line.
