BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a paint booth, and more particularly, to a paint booth having a paint space capable of painting work therein and configured to allow ventilation with the outside.

Conventionally, as this kind of paint booth, a dry baffle paint booth is known. The baffle-type paint booth is formed in a rectangular box shape with the front open, and a baffle plate serving as a first filter is placed upright inside the box-shaped booth body, and is formed behind the baffle plate. Two filters are arranged, and an exhaust chamber is formed behind the second filter. Furthermore, an exhaust blower is attached to the upper portion of the exhaust chamber, and the air in the booth main body is exhausted through the exhaust chamber, the baffle plate, and the second filter by the exhaust operation of the exhaust blower.

When spraying paint from a spray gun in the booth main body, the paint mist sprayed from the spray paint gun and dissipated in the booth main body is baffle plate (first filter) and The coating mist is sucked through the second filter to collect the coating mist and prevent scattering of the coating mist. In the conventional paint booth, a vortex chamber is provided in the booth, the vortex is generated in the exhaust air from the vortex chamber, the air and the paint mist are separated by the vortex, and the paint mist which is separated is collected in a water tank. There is a venturi type booth.

And as another form, the oil circulation type coating booth is also known.

By the way, painting work is always performed with sheet metal work, such as an outer panel of an automobile, for example. And as a size of the panel in which the painting is performed, the working panel which is 1 to 2 sheets occupies 70 to 80% of the whole.

Even in the work of such a small panel, there are restrictions on the use of organic solvents and the place of work (environment). In order to satisfy these restrictions, the work is often performed using a full-fledged paint booth using an iron plate, a heat insulating material, or the like to form a sealed box in earnest.

However, the full-scale painting booth is expensive and inexpensive to paint one or two panels.

Therefore, conventionally, the painting work is performed using the simple coating booth which uses a vinyl material.

Either of the full-scale painting booth and the simple painting booth described above are almost stationary, subject to site constraints, and are inefficient in terms of effective utilization of the working place.

In addition, in terms of the work process of sheet metal coating, there are background treatments such as putty and surfacer coating, color tone work, and drying work, and in the conventional paint booth, drying work takes a long time. There was a problem with efficiency.

In addition, in terms of organic solvents in the sheet metal coating industry, from the viewpoint of PRTR (Pollutant Release and Transfer Register), VOC (Volatile Organic Compounds) and fire extinguishing methods, etc. In addition to the production line of automobile manufacturers, it is necessary to take measures for environmental problems in the maintenance industry.

From this background, the materials used have also changed, and in the maintenance industry, a low solvent type paint having a low solvent use rate and a low solvent type paint to replace the low solvent type to which a specific chemical such as xylene toluene has been designated are reduced. Has been put into the market.

In addition, since it is a time when a lot of water-based paint is put into the market from the problem of deodorization, the low solvent, the above-mentioned PRTR method problem, the VOC countermeasure problem, etc., even in the maintenance industry, ie, the paint user side, the work technology changes with the change of the said material. And a review of the working environment is necessary.

For example, when water-based paints are used, drying is very late, which causes a decrease in work speed and an increase in cost.

In addition, as a conventional coating booth, Patent Document 1 proposes a painting booth capable of safely performing a body sheet metal painting work on a site of a gas station.

1 and 2, the longitudinal frames 1a to 1d, the ceiling frames 1i to 1l, and the longitudinal frames 1e to 1g are formed as one piece, respectively, and are manufactured as separate members to be welded or other means. You may join.

The four pantograph mechanisms 2a, 2b, 2c, and 2d are each of the outermost longitudinal frames 1a, 1d, 1e, and 1h of the frame member 1 and the inner side adjacent to each other in parallel with each other. The upper end is connected to each other in the X-shape between the vertical frames 1b, 1c, 1f, and 1g, and the lower end side and each connecting portion of each vertical frame 1a to 1h are rotatably connected to each other. The connection part of the side and each longitudinal frame 1a-1h is connected so that a sliding movement to an up-down direction is possible.

The vertical frames 1a, 1d, 1e, 1h, which are outermost frame members 1, and the vertical frames 1b, 1c, 1f, 1g, which are inner frame members 1 adjacent to each other in parallel with the above, By the action of the pantograph mechanism, the apparatus approaches or deviates while maintaining parallelism in the directions (inward direction) and the opposite direction (outward direction) approaching each other.

The air supply opening part 3 is provided in the ceiling surface, and the dryer mounting frame 4 for attaching or contacting the dryer 10 with a blower mentioned later is provided in the circumference | surroundings part. It is provided between the ceiling frame 1j and the ceiling frame 1k.

In addition, an exhaust opening 5 is provided in a part of the circumferential side surface of the paint booth (upper in FIG. 2), and an exhaust means for attaching a filter, an exhaust fan, and a duct hose, which will be described later, is installed in the peripheral portion thereof. The frame 6 is provided between the horizontal frame 1r and the horizontal frame 1s.

At the lower end of each vertical frame 1a to 1h, a caster 7 is provided and is configured to move freely on the floor or the like.

The above is the structure of the frame member 1 which forms the frame | skeleton of a coating space.

Next, the coating booth in which the cover member 8 was mounted on the said frame member 1 is demonstrated, referring FIG.

The cover member 8 is comprised of four side peripheral surfaces, namely, the front surface 8a, the right surface 8b, the left surface 8c, the back surface 8d, and the ceiling surface 8e. The front surface 8a of the cover member 8 is rolled upward to allow the object to be coated, for example, a car, to enter and exit, and a locking mechanism (not shown) is provided so as not to fall.

As the cover member 8, a thick vinyl material is joined or molded by means such as cutting, sewing, fusion, fixing of adhesive rivets, or surface fasteners. In FIG. 5, the rectangular part of the large frame of the four corners of the front surface 8a and the back surface 8d becomes the thick opaque auxiliary cover 9. As shown in FIG.

Each lower end portion of the subsidiary cover 9 is provided with a thick skirt portion 9a. The lower end portion of the cover member 8 is closed between the lower end portion and the mounting surface of the auxiliary cover 9, and the internal air is less likely to leak. .

Since the auxiliary cover 9 is joined between the adjacent cover members 8a and 8b and the cover members 8a and 8c by a surface fastener, the auxiliary cover 9 has a role of preventing air from entering at the joint portion.

Next, with reference to FIG. 3 and FIG. 4, the effective utilization of the space of the coating booth of this invention is demonstrated. In FIG. 3, the coating space is largest. On the other hand, in Fig. 4, the innermost vertical frame 1d and its inner longitudinal frame 1c, and the outermost longitudinal frame 1h and its inner longitudinal frame 1g are strongly inward. When the two are pushed to approach each other, the cover member 8 is folded as shown in Fig. 4 while maintaining parallel states with each other by the parallel movement functions of the pantograph mechanisms 2b and 2d provided between the respective vertical frames. As a result, the painting area inside the painting booth is reduced, which reduces the space occupied by the painting booth and further improves the space efficiency.

Next, with reference to FIG. 5 and FIG. 6, the attachment / detachment function of the dryer with a blowing function is demonstrated to the coating booth of this invention.

The dryer 10 shown in FIG. 5 is supported by a pair of longitudinal rails 100a disposed on the ceiling of a separate building and a transverse rail 100b fitted to be slidably fitted to the longitudinal rails. In addition, it is supported by the pantograph in the vertical direction to be caught in the desired position, whereby the dryer is movable horizontally and vertically along the guide rail, it is also possible to move up and down in the vertical direction. In addition, the attachment of the coating booth of the dryer 10 to the dryer mounting frame 4 does not necessarily need to be fixed using fastening means, such as a bolt and a nut, but it is a sealing member with heat resistance in both contact parts. May be configured so that the dryer 10 abuts on the dryer mounting frame 4 having the sealing material.

FIG. 6 is a perspective view of a second embodiment in which the dryer 10 is brought into contact with the air supply opening of the painting booth by movable stand means.

That is, the enclosure 10a of the dryer is movable up and down by the arm means 11 and at the vicinity of the tip side of the arm means 11, centering on the horizontal axis and the vertical axis not shown in the figure. And the bottom part is movable by the caster 12 provided in the lower part of the arm means 11, and the enclosure 10a which has a reflecting compartment is provided with the air supply opening part 3 It is comprised so that the dryer attachment frame 4 may be made to contact.

Since the dryer 10 arrange | positions the filter for vibration damping in the position of the intake side behind the housing | casing part 10a which abuts the air supply opening part 3, or the back of a blowing means, it is a coating film by air blowing. It is possible to effectively prevent damaging the quality of the.

Further, the blowing means is configured to blow air to the coating film while cooling the terminal portion of the heater tube protruding from the ventilation space or the required blowing space of the housing portion 10a to the required blowing gap. Therefore, it is possible to cool the temperature of the terminal portion to a lower temperature, whereby it becomes possible to make the heat generation temperature of the heat generating portion to a higher temperature, thereby further shortening the drying time of the coating film.

By the way, the present invention mainly paints in the interior of the paint booth (painting room), for example, the side door (fender), trunk (trunk), bumper, car hood of the car ( When some external surfaces such as a car hood are damaged or the like, the vehicle is stopped along the side circumferential surface of the paint booth (for example, the front surface 8a) or the paint booth is stopped. The cover member of the front surface 8a is rolled up in the state which moved to the painting surface side, the to-be-painted surface of a vehicle is enclosed with the cover member, and the painting operation can be performed on the painting room side by exposing the to-be-painted surface in a painting room. It is composed.

In this case, since the inside of the painting booth does not need a wide space, it is preferable to move the outermost frame inward and to fold the cover member, as described above, for the efficiency of the space.

In addition, when the to-be-painted surface of the vehicle is surrounded by the cover member 8, there is a possibility that a gap is generated between the vehicle and the painting booth, in which case the auxiliary cover member is attached to the adhesive tape and the surface fastener ), It is preferable to attach by hooks or the like to seal the gap.

The cover member 8 is configured to lift only a part of the side circumferential surface, for example, the front face 8a. The cover member 8 is not limited thereto, and the other left and right side surfaces 8b and 8c and the rear face 8d are not limited thereto. The back may also be openable. In this case, the side circumferential surfaces may be configured to be connected to each other by a surface fastener, a hook, or the like.

The coating booth of the present invention configured as described above, for example, moves the object to be coated in the painting room or moves the coating booth to the object to be coated to prepare for painting.

Then, the dryer 10 and an exhaust fan (not shown) are rotationally started. The dryer 10 does not apply electricity to the heater during painting or supplies a small power to ventilate the interior of the painting room (a so-called push-pull structure).

After painting is completed, the power supply of the heater of the dryer 10 is set to a predetermined value, and the coating film is strongly dried. The drying of the coating film varies depending on the coating process, and an appropriate temperature and drying time are set in the undertreatment (putty, surfacer, coloring work, painting work, etc.).

In any drying step, the drying operation can be performed quickly in a state in which the object to be coated is placed in the painting room, so that a significant improvement in the work efficiency can be seen as compared with the conventional apparatus.

After completion of the painting work, the dryer 10 is removed from the air supply opening 3, and an enclosure portion (hot air discharge portion) is disposed near the surface to be coated to dry the surface to be coated directly.

In addition, the ability of the conventional full-scale coating booth and the simple coating booth which concerns on this invention is demonstrated.

The shape of the conventional full-scale paint booth is an example, and is 2500 mm in height and 4000 mm in width and 7000 mm in length. The capacity of a general air supply fan in this painting room is 340 to 430 m 3 / min, and the capacity of the exhaust fan is 340. It is -430 m3 / min.

On the other hand, the shape of the coating booth which concerns on this invention is 2000 mm in height, 2600 mm in width, and 2100 mm in length.

The capacity of the air supply fan of the dryer 10 according to the present invention is 40 to 44 m 3 / min, and the capacity of the exhaust fan is 37 to 55 m 3 / min, even if compared with the ventilation performance of the conventional full-scale paint booth. On the contrary, the wind speed in the painting booth according to the present invention is two to three times faster than the full booth, while the wind speed is generally 0.2 to 0.4 m / min. In view of the above, sufficient response is also possible to the paint of the late evaporation type, such as an aqueous paint, and the high boiling point liquid type paint, and can exhibit favorable effect.

By the way, the painting booth which concerns on this invention is not fixed as a work place in the field work, but the caster is attached to the lower part of the frame member, and the caster is also attached to the stand arm means which supports the dryer 10. In addition, in the type of hanging dryer 10, the rails are movable horizontally and vertically by guide rails. Therefore, the coating and drying locations can be freely changed in the factory. We can use space effectively.

The conventional coating booth had the inconvenience of having to carry over the work by moving a repair vehicle to a painting place after completion of the ground treatment process. According to the painting booth according to the present invention, a repair area of about one to two panels is provided. In this case, it is possible to carry out from the ground coating, repainting, and drying work in the same place regardless of the place.

This means that the sheet metal painting operation is greatly improved, and at the same time, it contributes to the significant cost reduction of the substrate related to the painting.

In addition, the coating booth according to the present invention can be moved horizontally and vertically by a dryer having a blowing function, so that the dryer is in contact with the air supply opening at the time of painting and is in communication with the interior of the painting booth for use for ventilation. When drying, it is separated from the air supply opening, and moved to the surface to be coated which needs to be dried, and a box (hot air ejection part) having a reflecting compartment of the dryer can be used to dry by installing a predetermined distance away from the surface to be coated.
