Description

[Detailed description of the device]

[0001]

[Industrial application] The present invention relates to a coating booth. More specifically, the present invention relates to a coating booth having a dew condensation preventing effect on equipment installed in the coating booth.

[0002]

2. Description of the Related Art Conventionally, in order to prevent dew condensation on equipment such as an automatic coating machine installed in a coating booth, the equipment is warmed up.

[0003]

[Problems to be Solved by the Invention] There has been a problem that energy is wasted in preventing condensation by warming up conventional equipment.

[0004]

[Means for Solving the Problems]

A blower that introduces heated and / or humidified outside air into the coating booth, a rectifier that separates the introduced outside air into each process in the coating booth, and a blower installed in each process in the coating booth A paint booth, characterized by comprising an exhaust device with variable exhaust capacity for exhausting the introduced outside air,

Providing

[0007]

[Function] When there is a dangerous condition that dew condensation occurs on equipment in the process where equipment that requires dew condensation prevention during the process in the coating booth is installed, warmed outside air is introduced into the paint boot, In addition, operate the exhaust system installed in the process where the equipment is installed with higher capacity than other exhaust systems. Then, the heated outside air concentrates on the process in which the equipment is installed.

When there is no risk of dew condensation on the equipment, the operation of the exhaust system is returned to the same level. Humidify the air if necessary.

Embodiment An explanation will be given according to FIG. 1 showing a central sectional view of an embodiment of the present invention.

Reference numeral 11 denotes a coating booth, which is hollow. A blower 12 introduces outside air into the coating booth 11. The blower 12 is provided with a heating device and a humidifying device to heat or humidify the outside air introduced.

F1, F2, F3, F4, F5, and F6 are coating processes sequentially performed in the coating booth 11. Reference numeral 31 is an automatic coating machine installed in the coating booth 11. The automatic coating machine 31 is installed in each of the processes F2 and F5. Since the automatic coating machine 31 is a device, dew condensation occurs depending on temperature and humidity conditions.

Reference numeral 21 is a rectifying device including a rectifying plate, and 22 is a blower passage that connects the blower 12 and the coating booth 11 to each other. The rectification device 21 is classified according to the process steps F1, F2, F3, F4, F5, and F6 in the coating booth 11 at the introduction portion of the air passage 22 into the coating booth 11.

Reference numeral 23 is an exhaust device. The exhaust device 23 is installed in each process F1, F2, F3, F4, F5, F6 in the coating booth 11. The exhaust device 23 can change the exhaust capacity for exhausting the introduced outside air by an inverter or the like.

As a device that needs to prevent dew condensation during the process in the coating booth 11, when the automatic coating machine 31, which is a device installed in the processes F2 and F5, has a dangerous condition to cause dew condensation, the blower 12 The outside air heated in step 1 is introduced into the coating booth. At the same time, the exhaust device 23 installed in the processes F2 and F5 in which the automatic coating machine 31 is installed has a higher capacity than other exhaust devices and is set to, for example, doubled to operate. Then, the heated outside air concentrates on the steps F2 and F5 in which the device 31 is installed as indicated by the arrow shown by the solid line in FIG. It warms up in a short time because the hot air is blown to the necessary places.

Under the condition that there is no risk of dew condensation on the device 31, the operation of each exhaust device 23 is returned uniformly. Then, the outside air is uniformly introduced into each process as indicated by the arrow shown by the broken line in FIG. If necessary, the blower 12 humidifies the outside air.

[0016]

[Effects of the Invention] Therefore, in the present invention, the time for warming up the equipment for preventing the occurrence of dew condensation is reduced and the energy loss is reduced.
