Description

  The present invention relates to a cutting waste leveling unit and a shredder device that level the cutting waste accommodated in the shredder device to make the height of the cutting waste substantially uniform.

  Conventionally, the cutting waste cut by the cutting unit built in the shredder apparatus falls into a cutting waste container disposed below the cutting unit.

  Usually, the shredder device is provided with a cutting waste detection sensor, and when the cutting waste container is full of cutting waste, the cutting waste detection sensor detects the state and forcibly stops the operation of the cutting unit. An alarm is generated to notify that the cutting container is full of cutting lines (eg, blinking red light). Then, when the administrator of the shredder apparatus takes out the cutting waste from the cutting fault container and empties the cutting waste container, the cutting unit returns to an operable state.

  Further, when the cutting waste is simply accommodated, the volume of the cutting waste is much larger than the volume of the sheet before cutting. For this reason, when the cutting waste detection sensor detects that the height of the cutting waste has reached the predetermined height, the cutting waste in the cutting waste container can be leveled, and further, the cutting waste can be stored in the cutting waste container. The technique to do is disclosed (refer patent document 1).
