2D Code Reader

SIGNUM 2 DC

The SIGNUM 1DC / 2 DC inspection system is a system for the inspection of codes that is used, among other things, on packaging machines in the pharmaceutical industry, but also in the food and pharmaceutical industries.

The intelligent cameras evaluate prints of 1D and 2D codes with exceptionally high reading performance. The optionally available control unit includes a PLC to enable retrofitting to an existing system.

The comprehensive software features enable producers and packagers to optimally evaluate even difficult optical conditions. In addition, scanware offers analysis tools that enable error analysis and thus the reduction of reject.

Inspection criteria and objects

Testable objects:

  • Labels
  • Package inserts

  • Code 32, Code 39, Code 128
  • Interleaved 2/5
  • DatenBar
  • Pharmacode

 

2D-Codes:

  • DataMatrix

Advantages of the 2D code readers

Available in various designs for simple and optimal system integration. The simple, user-oriented operation and the guided learning run make the system particularly user-friendly. Since only relevant areas are read, very high reading speeds of 150 barcodes and 80 DataMatrix codes per second are possible.

Error analysis enables improvements to be made to the codes, and all common codes are already incorporated. The evaluation is independent of the rotational position and transport direction of the test item and can work reliably even at high transport speeds of up to 6 m/s.

Software facts of 2D code inspection

The software offers the operator the possibility to implement the evaluation and improve productivity even without prior knowledge of coding.

Standard criteria are stored for all types of codes and can be adapted as required. The quiet zone that must be present around a code so that it can be read reliably is automatically included and visualised by the software. The evaluation of faulty codes precisely identifies their deviation. This means that errors can be corrected more quickly and further ejections can be avoided.

The reading results in the running machine are also visualised so that errors that occur in the interval are detected.
