Definitions

  • the invention relates to a device for cutting stacked, sheet-like good, with a table for receiving the good, whereby a back part of the table the material to be cut and a front part Table part receives the cut material, also with one in the area the rear table part arranged feed device for the Good, a side stop for the good, and one above the Table arranged portal frame, which is a knife for cutting the Good thing is a press beam that can be lowered onto the material to be cut and on the side facing the front table part a control panel and has a display field.
  • Such a device is for example from EP 0 056 874 A1 or DE 196 37 027 A1.
  • devices for Cutting sheets present in stacks, in particular of paper, Cardboard, foils or the like especially in the case of collective sheets, must Advance the saddle under the knife to be very accurate to ensure that the stack of knives at the desired dividing line is cut. Already slight shifts, for example Dimensional deviations due to paper distortion can lead to the The knife is not cut at the desired dividing line, but is shifted from it.
  • the individual patterns would be cut. To prevent this, the collecting sheets are printed in such a way that the individual patterns do not come into direct contact with one another, but remain between these distances.
  • the operations to be monitored by the operator on the rear part of the table, to rule out quality defects are of various types. For example, those that are next to each other when cutting collecting sheets Stack in the area of their upper sheet layers on the feed device run up, stacks may be shifted, individual sheets can be displaced, for example by blowing air, that warp the top layers of sheets. Especially if the cut sheets are not printed with cut marks Operator hardly possible to monitor the rear part of the table because the individual sheet layers without visible reference markings to run.

Only in this case the operator has to go under the portal frame, for example reach through and the correction by means of a utility angle the lateral alignment of the stack of material to be cut carry out, or from the front the or the material to be cut Align with the feed device using the utility angle.
  • the life image of the area is advantageously displayed of the rear part of the table arranged camera in the display panel only during the alignment of the material to be cut on the feed device and / or the side stop.
  • a further optimized operator guidance is then given if the life picture is only when the goods are misaligned displayed on the feed device and / or the side stop becomes.
  • the operator can thus completely focus on the cutting process and concentrate on the operation of the cutting machine Fading in the life image signals that an alignment process only is insufficient and thus a correction of the to be cut Good things required on the feed device and / or the side stop is.
  • the cut is triggered of the knife in the event of a misalignment of the goods on the feed device and / or the side stop is ineffective.
  • the operator can thus only cut with the machine if the material to be cut is correct aligned with the feed device and / or the side stop is. This significantly improves the quality of the cut Product at.
  • a separate monitor can be shown in the display panel of the life image.
  • a preferred design provides, however, that the cutting device has a display, that of the graphical representation of different machines or Workflows, with the life image of the Camera can be faded in.
  • the graphic display can be shown here partially or completely through the Life picture to be replaced. Only partially replaces the life picture graphic display on the display, can be in the remaining area of the Displays the most important operating and status functions at the same time the device can still be played.
  • the operator is thus a life picture in the area of displayed by him clearly visible, whereby he due the transfer of a life picture immediately the situation of the Cuttings in the area of the rear part of the table, the correction and finally the exact alignment of the material to be cut with the Can monitor feed device and / or the side stop.
