A ventilation device is provided, and a treatment device for treating excess spray paint mist discharged together with ventilation air and falling paint slag is provided below the painting work area, and a work floor is provided above the treatment device. Regarding the booth.

[Conventional technology]

Conventionally, in the coating booth as described above, in order to allow passage of ventilation air (exhaust air), passage of excess sprayed paint mist discharged together with the ventilation air, and passage of paint slag from the coating work area to the lower processing equipment. In addition, the working floor is made of a perforated plate such as grating or expanded metal, and the flooring of a predetermined size made of these perforated plates is arranged in a state of being mounted and supported on a support frame to form the work floor. Had formed.

[Problems to be Solved by the Invention]

However, although the floor material is a perforated plate, it is unavoidable that paint mist or paint slag adheres to and accumulates on the working floor during painting, and the adherence and accumulation gradually progresses and the working floor becomes clogged. As a result, the discharge of the excess sprayed paint mist from the coating work area is hindered, and the airflow state of the ventilation air in the coating work area changes, resulting in a problem that the finish quality of the automatic spraying coating deteriorates.

In order to avoid such deterioration of quality, floor materials are regularly removed and the coating material is peeled off by various devices. There has been a problem that the paint removal work requires a lot of labor and cost.

An object of the present invention is to solve the above-mentioned problems by improving the working form of the working floor.

[Means for Solving the Problems]

The characteristic configuration of the coating booth according to the present invention is that a ventilation device for flowing ventilation air for removing excess spray paint mist downward is provided in a coating work area where an automatic spray coating device is installed, and ventilation is provided below the coating work area. In a configuration in which a treatment device for treating surplus sprayed paint mist discharged with air and falling paint slag is provided, and a work floor is provided above the treatment device, the work floor is above the treatment device in a substantially horizontal posture. There is a drive device that operates to move between the used position and the storage position where the excess spray paint mist and the falling paint slag are removed from the passage and the passage is opened. On the street.

[Work]

In other words, in a coating booth that performs automatic coating with an automatic spray coating device, workers do not enter the coating booth during coating, and the work floor is used for various maintenance work in the booth when the coating operation is stopped. Used only when entering the painting booth.

Therefore, during painting, when the work floor is not used, the work floor is moved by the drive device to the storage position where the work path deviates from the passage of the excess spray paint mist and the falling paint slag and the passage is opened. By doing so, it is possible to prevent paint mist and paint slag from adhering to and depositing on the work floor, and not only to avoid adhering and depositing paint, but also to ventilate air discharged from the painting work area into the discharge path itself. Can be performed more smoothly than before in a state where there is no (that is, in a state where the path is open), so that the dischargeability of the excess sprayed paint mist to the lower processing device side can be improved compared to before. At the same time, the airflow state of the ventilation air in the painting work area can be maintained more stably in a predetermined state.

On the other hand, when the worker enters the coating booth when the coating operation is stopped, the work floor can be used by moving the work floor to the original use position above the processing device in a substantially horizontal posture by the drive device. The worker can perform various maintenance work in the booth as before, and, of course, the paint operation is stopped even when the work floor is in the use position, so the paint mist and The paint slag does not adhere to the work floor, and the work floor does not affect the painting.

〔The invention's effect〕

As a result, without any loss of usability of the work floor,
Also, while eliminating the work of removing the adhered paint and the work of removing and attaching the floor material, which required a lot of labor and cost in the past, it is possible to improve the dischargeability of the excess sprayed paint mist and to ventilate the air in the painting work area. By improving the stability of the air flow state, it is possible to improve the finish quality of spray coating,
