Description

  The present invention relates to a label sticking apparatus that can determine whether a bar code displayed on a label is good or bad.

  Conventionally, there is a label sticking device that can read a barcode printed on a label surface as disclosed in Patent Document 1 with a scanner and detect the quality of the barcode. The scanner of this label applicator is installed in a transport path (a path between a printing unit that prints on the label surface and a holder that holds and affixes the label) and reads a barcode.

  Detecting the quality of the bar code described above is based on whether the bar code is displayed on the label without missing or the bar code can be read by the scanner, or the bar code data is normal after the bar code is read by the scanner. This means detecting whether the code is normal or not.

  However, since the scanner of the conventional label applicator was installed in the transport path, when the label continuum, in which a number of labels are temporarily attached to the belt mount, meanders and floats in the transport path, the scanner labels There is a problem that the barcode on the surface cannot be read or the reading state becomes unstable, the barcode surface is not missing, and an error occurs even if the barcode is a normal data.
