LSC 5

 

A non-contact inspection system for liquid container blanks

 

LSC 5L is an inspection system for quality control, designed for purposes of liquid container manufacturing industry. The inspection system compares actual container blanks to their standard values. 

 

Measurement principles of LSC 5 Length Measurement:

A linear positioning unit moves the blank below a high resolution CCD-linecamera. The blank is scanned and measured automatically without contact.

The measurement principle of LSC 5L is based on visible brightness signatures (creases and cuts) at the surface of the blank. Therefore the LSC5L system contains a special designed illumination unit. The so-called super user mode of the LSC5 software allows to define measurement instructions. These instructions typically contain:
        length to be measured, starting or ending at cuts or creases
        instructions to check the orthogonality of crease lines
        instructions to check knife positions
        labels, standards and tolerances for every measurement item

After putting a blank onto the linear positioning unit, the user selects the measurement instruction from a list. Hereafter the blank is scanned and the result is evaluated by a PC. LSC5 supports sequence measurements.

 

Results of measurement:

The protocol of a measurement can be printed out or stored in a file. In case of sequence measurement the result is added to a file which can be processed by spreadsheet programs. The result of the measurement can be printed out together with a scematically drawn blank.

Technical information:

Measurement dot (depending on the maximum size of blank) typically                     50 Microns
Measurement precision (depending on the maximum size of blank) typically             100 Microns
Measurement speed (depending on the number of inspection lines) typically             45 sec
