  • An adjustment of the gap dimension can be made both with the aid of data of the carrier web as well as the grid track. If, in the following, an increased focus is placed on the observation of the grid track, an analogous consideration of the carrier track is generally possible. In this respect, it is assumed that when the sensors record data about the state of the grid track, alternatively, data of the carrier web can be used.
  • the grid rail offers advantages in using sensors incorporating depth information due to the large differences between the punched and non-punched areas.
  • the carrier web may e.g. offer advantages in printed labels due to greater contrast between labels and underlying carrier web.
  • the desired state which is used as the basis for determining a deviation of an actual state, can be predefined or predefinable, for example, as described above.

  • a manually and optimally adjusted system can first be visually checked by an operator to then initialize the learning phase, for example, via the control unit of the control system.
  • the control program learns the lattice or carrier web pattern resulting in this set desired state by possibly processing and storing the signal resulting from the sensors in this regard.
  • an image of the signal can also be stored, for example in order to reduce the number of data used and to require less storage space or to be able to better compare the actual and desired states.

  • the system can be informed depending on the sensor not only on the presence or absence of one or more labels in the grid web, but also on the material of the grid rail, on any imprints and contours and about the distance of the grid rail.
  • the evaluation unit can also use for calibration purposes, the data of a reference sensor of the punching device for signal analysis, wherein the reference sensor as a rotary or position sensor, which is attached to the punching cylinder, as a rolling wheel on the cylinder, as a microswitch or other one or more full or partial revolutions the punch cylinder indicative sensor, which is optionally attached to the frame of the device may be formed.

  • the data can be normalized to compensate for differences in web speed.
  • a virtual time base can be formed against the background of the signal obtained from the reference sensor.
  • data images can be separately defined as the desired state for each sensor so that the correspondingly adapted data of the sensor or its image can be compared with the reference pattern of the desired state during normal functional operation. Too large a deviation from the reference pattern is considered an error indicating, for example, a label in the grid path.
  • an error can already lead to an automated readjustment of the punching device.
  • the gap size can be reduced.

  • a line scan camera which is tuned to the carrier and / or the grid track.
  • color gradients or surface materials of the grid can be taken into account in the creation of the desired state.
  • a line scan camera or even a 2D or 3D camera which can determine the arrangement of the grid in space, is advantageous for an automated adjustment of the gap dimension of the punching device, since the signal evaluation over the preferably entire width of the material web, punched out in the labels be possible in a simple manner and even any frays or partially stuck labels can be detected.
  • the device can thus be readjusted in more detail.
  • a gap which is too large, but also a too small one can be recognized, for example, by the fact that a label which can be produced with punching edges of lesser height, which is e.g. can be generated laterally in the web, but is punched out. Accordingly, monitoring of the corresponding material web position can be set up in the evaluation unit and this specific deviation does not lead to a reduction of the gap dimension. If an excessive depth punching is detected in this or another way, can be activated automatically or automatically via an operating unit automatic delivery, such that the gap is automatically increased so far that labels stuck in the grid track and then subsequently an adjustment of the Gap automatically takes place until no more tags get stuck.
