  • the bracket to which the blast fan is attached is firmly fixed to the suspending bar via, for example, a fastening member such as a bolt & nut, there arises a problem that the blast fan cannot be shifted easily and quickly to desired positions according to the size or the material of the sheet to be printed, so that it requires long time for an adjustment work.
  • a sheet-discharging apparatus for a sheet-fed printing press includes a fan device having a plurality of blast fans provided above a sheet-stacking position where sheet fed from a printing apparatus are stacked for providing a downward flow and a frame for mounting the blast fans, in which at least some of the plurality of blast fans are arranged in contact with the lower surface of a frame body corresponding to elongated openings formed on the thin-plate shaped frame body which constitutes the frame, and are slidable in the feeding direction and/or in the widthwise direction with respect to the frame body.
  • the blast fans are directly attached to the frame body so that the upper surfaces of flange portions formed into an annular (doughnut) shape at upper ends of the blast fans and the lower surface of the frame body come into abutment with each other, the dimension of the fan device in the height direction may be reduced to the substantially same dimension as the thickness of the blast fan, so that the fan device is downsized, and the visible range of the operator (personnel) of the sheet-discharging device may be widened, thereby improving the visibility.
  • the upper surface of the frame body may be formed into a shape having less concavo-convex, which facilitates cleaning, dust such as paper flour or powder accumulated on the upper surface of the frame body may be removed easily, and hence the cleaning work of the fan device may be simplified, whereby the working time required for the cleaning operation may be reduced.

  • partitioning panels formed into an endless ring are provided so as to project upward from the upper surface of the frame body along the peripheries of the openings.
  • the dust such as paper flour or powder accumulated on the upper surface of the frame body is prevented from dropping downward (that is, toward the sheets stacked on the paper discharge table) through the openings by the outer peripheral surfaces (radially outer surfaces) of the partitioning panels, and hence the upper surface of the sheets stacked on the sheet-discharging table may be maintained in a clean state, and the sheets are prevented from becoming damaged, and hence the quality of the printed materials is improved.
