Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to a coating booth.

[0002]

2. Description of the Related Art FIG. 5 shows a conventional construction of a coating booth. In the figure, reference numeral 1 is a coating booth body. The coating booth 1 main body includes a coating room 2, an air supply room 5, and a paint mist removing room 6
Is provided.

A work (for example, an automobile body) W sent to the coating chamber 2 by a conveyor 51 is coated by a paint spraying means (for example, an automatic coating machine or a coating robot) 9. External air is supplied into the coating chamber 2 from an air supply chamber 5 located above. Further, the air containing the paint mist generated during the coating in the coating chamber 2 is exhausted to the lower paint mist removing chamber 6 through the permeable floor surface 10P.

In the paint mist removing chamber 6, the paint mist is collected by gas-liquid contact by a venturi type paint mist removing device 7. The air cleaned by collecting the paint mist is discharged into the atmosphere by an exhaust fan (not shown).

Here, the floor surface 1 of the coating room 2 described above
As shown in FIG. 5, the 0P is composed of a pedestal 11 and a large number of funnel-shaped floor surface forming members 12 supported on the pedestal 11.

The pedestal 11 is formed of a large number of shaped steels and the like, and has a structural strength that supports each floor surface forming member 12 and allows an operator to walk on the floor surface forming member 12 safely. It is said that.

Further, as shown in FIG. 6, the floor surface forming member 12 has a square (or rectangular) shape with one side L of 500 to 600 mm, and is used by a worker for maintenance and inspection work in the coating chamber 2. Is said to have structural strength such that it can walk on it. Therefore, it generally has a considerable weight (for example, 10 to 15 kg).

By the way, to each floor surface forming member 12 constituting the floor surface 10P, paint mist or raw paint discharged at the time of switching the coating color is attached. Therefore, when the painting work is performed in the painting chamber 2 for a certain period of time, a large amount of paint adheres to each floor surface forming member 12, and the ventilation performance is significantly reduced. When such a situation occurs, an excessive load is applied to the exhaust fan and the like, and the exhaust gas in the coating chamber 2 becomes insufficient.

Therefore, conventionally, the floor surface forming member 12 is regularly cleaned. When performing such cleaning work,
The worker removes the members 12 that have adhered to each other due to the adhered paint one by one with a bar or the like, then carries them to a cleaning place outside the main body 1 of the coating booth and cleans them with chemicals to remove the paint. is doing. The cleaned floor surface forming member 12 is transported to the inside of the coating chamber 2 and mounted again on the pedestal 11.

[0010]

By the way, in the above-mentioned floor surface cleaning work, it is necessary to spend a great deal of time and labor for removing, transporting, and mounting the floor surface forming member 12, which is a heavy object, It will put an excessive burden on the worker.

Therefore, there is a strong demand for early development of a technique for eliminating such inconvenience. However, in the development of the technique, there are restrictions on the installation of equipment (paint spraying means 9 etc.) in the coating room 2 and the coating booth. It is required not to upsize.

[0012] In view of the above circumstances, an object of the present invention is to restrict the installation of equipment in the coating chamber or to increase the size of the equipment,
An object of the present invention is to provide a coating booth that can prevent the floor surface from being contaminated with paint while ensuring smooth exhaust in the coating chamber.

[0013]

[Means for Solving the Problem] The floor surface of the coating room is necessary when an operator enters the coating room to perform work (maintenance / inspection, etc.). The present invention has been made paying attention to the fact that the ventilation resistance is reduced and the paint does not become dirty.

That is, the coating booth according to the present invention is a coating booth in which the floor surface of the coating chamber in the coating booth main body comprises a pedestal and a plurality of floor surface forming members supported on the pedestal. In the main body, there is provided a storage portion capable of storing at least a floor surface forming member corresponding to the work coating area among the floor surface forming members at a position lower than the floor reference surface and retracted from the work coating area, A floor surface forming member is housed in the housing portion so that an opening can be formed on the floor surface of the coating chamber.

[0015]

In the present invention having the above-described structure, at the time of coating, the floor surface forming member corresponding to the work coating area can be removed from the mounting portion on the pedestal and stored in the storage portion below the floor reference surface. As a result, on the floor surface of the coating room, an opening having no resistance to the flow of air will be formed,
The ventilation resistance is greatly reduced to ensure smooth exhaust, and the floor surface (floor surface forming member) is not contaminated by the paint.

In addition, when maintenance and inspection are to be performed in the coating room when the coating is stopped, the floor surface forming member is taken out of the accommodating portion and the original position on the mount (that is, the opening).
Can be attached to. As a result, the opening on the floor disappears, and the worker can walk safely on the floor to smoothly perform maintenance and inspection.
