In particular, the present invention relates to a gravure printing apparatus that can reduce the cost required to adjust the humidity of air in a sealed room and a drying room.

  Conventionally, a gravure printing machine having a sealed chamber, a gravure plate cylinder and an impression cylinder which are provided in the sealed chamber and prints on a web, and a drying chamber located downstream of the gravure plate cylinder and the impression cylinder A gravure printing system equipped with is known. Further, in the gravure printing system 20, as shown in FIG. 3, a sealed chamber humidity adjustment air supply device 22 that supplies humidity-adjusted air is provided in the sealed chamber 21, and a drying chamber of the gravure printing machine 23 is provided. 24 is provided with a humidity adjusting air supply device 25 for drying chamber for supplying air whose humidity is adjusted.

  In such a gravure printing system 20, when adjusting the humidity of the air in the sealed chamber 21, first, the air outside the sealed chamber 21 is taken in by the humidity adjusting air supply device 22 for the sealed chamber, and the humidity is adjusted. The air is supplied to the sealed chamber 21 through a sealed chamber supply pipe 26 connected between the operating humidity adjusting air supply device 22 and the sealed chamber 21. Thereafter, the air is exhausted from the sealed chamber 21 to the outside of the sealed chamber 21 through the sealed chamber exhaust pipe 27 provided in the sealed chamber 21. On the other hand, when the humidity of the air in the drying chamber 24 of the gravure printing machine 23 is adjusted, first, the air outside the sealed chamber 21 is taken into the humidity adjusting air supply device 25 for the drying chamber, and the humidity is adjusted. The air is supplied directly to the drying chamber 24 through the drying chamber supply pipe 28 connected between the regulated air supply device 25 and the drying chamber 24. Thereafter, the air is exhausted from the drying chamber 24 directly to the outside of the sealed chamber 21 through the drying chamber exhaust pipe 29 provided in the drying chamber 24.

  However, in the above-described gravure printing system, a humidity adjusting air supply device for a sealed chamber and a humidity adjusting air supply device for a drying chamber are provided in order to supply humidity-adjusted air to the sealed chamber and the drying chamber, respectively. Therefore, installation costs for installing these humidity-controlled air supply devices for sealed rooms and humidity-controlled air supply devices for drying rooms, and operating humidity-controlled air supply devices for sealed rooms and humidity-controlled air supply devices for drying rooms Therefore, it is difficult to reduce the cost required for adjusting the humidity of the air in the sealed room and the drying room.

  Further, when operating the humidity adjusting air supply device for the closed chamber and the humidity adjusting air supply device for the drying chamber, a relatively large amount of operating energy is required for the operation, which hinders energy saving.

  The present invention has been made in consideration of such points, and provides a gravure printing system capable of reducing the cost required for adjusting the humidity of air in a sealed chamber and a drying chamber of a gravure printing machine. For the purpose.

  The present invention relates to a gravure printing having a sealed chamber, a gravure plate cylinder and an impression cylinder which are provided in the sealed chamber and which prints on a web, and a drying chamber located downstream of the gravure plate cylinder and the impression cylinder.

  The present invention is provided with a hermetic chamber humidity measuring means for measuring the humidity in the hermetic chamber in the hermetic chamber, and the humidity measuring means for hermetic chamber is based on the measured value measured by the hermetic chamber humidity measuring means. A gravure printing system to which a control device for controlling a humidity adjusting air supply device is connected.

  The present invention is provided with a drying chamber humidity measuring means for measuring the humidity in the drying chamber in the drying chamber of the gravure printing machine, and the measurement value measured by the drying chamber humidity measuring means is transmitted to the control device, The control device is a gravure printing system that controls the humidity adjusting air supply device based on a measured value from the sealed chamber humidity measuring unit and a measured value from the drying chamber humidity measuring unit.

  According to the present invention, humidity-adjusted air is supplied to the sealed chamber by the humidity-adjusted air supply device, and the air in the sealed chamber is introduced into the drying chamber through the air inlet provided in the drying chamber of the gravure printing machine. Then, the air in the drying chamber is exhausted directly outside the sealed chamber through an exhaust pipe provided in the drying chamber. Thus, the humidity of the air in the sealed chamber and the drying chamber can be adjusted with one humidity adjusting air supply device. For this reason, compared to the case where separate humidity adjustment air supply devices are installed and operated for the sealed chamber and the drying chamber, the installation cost for installing the humidity adjustment air supply device and the humidity adjustment air supply device are operated. Therefore, the operating cost for the operation can be reduced, and the cost required for adjusting the humidity of the air in the sealed room and the drying room can be reduced. In addition, the operating energy required to operate the humidity-adjusted air supply device can be reduced compared with the case where separate humidity-adjusted air supply devices are operated for the sealed chamber and the drying chamber.
