PURPOSE:To vaporize drops of water while washing surfaces of punches, and to prevent rust, by ejecting steam for finish cleaning after ejecting pressurized warm water to punches of a tablet machine in preliminary cleaning. CONSTITUTION:A punch set box 1 containing punches 2 to be cleaned is put in a cleaning chamber 11 from an entrance door 5, which is then closed. When the box 1 moves forth to turn on a limit switch LSW1, a motor 8 drives a roller conveyor 13 to right and also allows a motor 10 to start simultaneously, thus ejecting a pressurized warm water, which has 5-7kg/cm<2> and 50-60 deg.C from nozzles 3 over the box 1. When the box 1 reaches a limit switch LSW2, the motor reverse to move the box 1 to left, and also permits ejection of steam with 2-3kg/cm<2>. Further, when the box 1 reaches the limit switch LSW1, the motor 8 turns normally again to move the box 1 to right. Thus, the box 1 slides between the limit switches LSW1 and LSW2 to eject the warm water over respective punches in the former half and the steam in the latter uniformly. |
