Description

painting room

technical field

The present invention relates to a painting booth, and more specifically, relates to a painting booth having a painting space capable of performing painting operations inside and capable of ventilating with the outside.

Background technique

Conventionally, a dry-type mask-type paint booth is generally known as such a paint booth. The baffle-type painting room is formed in a rectangular box shape with an open front, and a baffle as a first filter is erected inside the box-shaped room body, and a second filter is arranged behind the baffle. The exhaust chamber is formed behind the 2 filters. In addition, an exhaust fan is installed on the upper part of the exhaust chamber, and the air in the chamber body is exhausted through the exhaust chamber, the baffle, and the second filter through the exhaust action of the exhaust fan.

When spraying paint from a spray coating gun in the chamber body, the spray mist sprayed from the spray gun into the chamber body passes through the baffle (first filter) and the second filter. Absorb and collect paint mist to prevent spray mist from scattering. In addition, as the form of the conventional painting booth, there is a Fenqiu type room with the following structure. A vortex chamber is provided in the chamber, and the exhaust gas is vortexed in the vortex chamber, and the air is vortexed by the vortex. Separate from the paint mist, and collect the separated paint mist in the water tank.

As another form, an oil circulation type paint booth is also known.

However, for example, painting work must be performed simultaneously with sheet metal work on automobile outer panels and the like. And as the size of the boards to which this coating is applied, 1 to 2 boards account for 70 to 80% of the whole.

In the work of such small boards, there are also restrictions on the use of organic solvents and restrictions on the workplace (environment). In order to meet this restriction, a truly sealed box shape is often formed, and a regular type of paint booth is used for work. The paint booth uses iron plates, heat insulating materials, and the like.

However, the above-mentioned standard-type paint booths are expensive and uneconomical for painting 1 to 2 boards.

Therefore, in the conventional technology, painting is actually carried out using a simple type painting booth using vinyl resin materials.

Most of the above-mentioned regular type painting booths and simple type painting booths are fixed-type and are not suitable for effective use of workplaces due to space constraints.

In addition, in terms of the work process of sheet metal coating, there are primer treatment such as putty and putty coating, color matching work, and surface coating drying work. In the conventional painting room, drying work takes a lot of time. There is a problem with work efficiency.

In addition, in recent years, organic solvents in the sheet metal coating industry have been investigated from the perspectives of the PRTR method (Pollutant Release and Transfer Register: chemical substance discharge control management promotion method), VOC countermeasures (Volatile Organic Compounds: volatile organic compound countermeasures), fire protection law, etc. See, not only the production lines of automobile manufacturers, but also in the repair world must take measures against environmental problems.

From this background, the materials used are also changing. In the maintenance industry, low-solvent types with low solvent usage rates or solvents designated as specific chemicals called xylene and toluene should be reduced, and low-solvent type paints that replace them should be used. market.

In addition, starting from the problem of deodorization, low solvent, the above-mentioned PRTR method problem, and the problem of VOC countermeasures, etc., since water-based paints have begun to be put on the market in large quantities, the maintenance industry, that is, paint users, must also change the above-mentioned materials. Facing the operating technology and operating environment again.

For example, in the case of using water-based paint, since the drying is very slow, the work speed is slow, which becomes a major cause of cost increase.

Incidentally, as a conventional painting booth, Patent Document 1 proposes a painting booth in which vehicle body sheet metal coating work can be safely performed in a gas station site.

That is, the vehicle body sheet metal coating room for a gas station described in Patent Document 1 has: a vehicle body sheet metal coating space for performing sheet metal coating; a roof part provided above the vehicle body sheet metal coating space ; explosion-proof air supply fan, which is located on the top cover and is used to blow outside air into the vehicle body sheet metal coating space; The air blown in by the explosion-proof air supply fan is purified; the exhaust filter is arranged on any side of the side surface of the vehicle body sheet metal coating space and is used to purify the polluted air in the vehicle body sheet metal coating space Exhaust box, it is arranged on the outside of this exhaust filter, is used for storing the air purified by this exhaust filter; Explosion-proof exhaust fan, it is arranged on this exhaust box, is used for this exhaust box The air stored inside is discharged to the outside; the control panel is used to control the explosion-proof air supply fan and the explosion-proof exhaust fan.

With the coating booth thus constituted, there is no risk of fire from flammable gases such as thinners floating in the vehicle body sheet metal coating space, flammable gas agent paint, etc., and the working environment is also good. Considering the fire protection law, it also takes into account VOC countermeasures.

Detailed ways

Next, a painting booth according to an embodiment of the present invention will be described with reference to the drawings.

Fig. 1 is a schematic structural perspective view of the frame group member of the first embodiment of the painting booth according to the present invention seen obliquely from above, and Fig. 2 is a frame group of the painting booth shown in Fig. 1 seen from directly above A three-dimensional view of a model structure of a component, etc.

In Fig. 1 and Fig. 2, the skeleton group member 1 forms a roughly cuboid painting space as a whole, including: left and right four vertical frames 1a, 1b, 1c, 1d and 1e, 1f, 1g, 1h; top frames 1i, ij, 1k, 1l, 1m, 1n; horizontal frame 1o, 1p, 1q, 1r, 1s; zoom mechanism 2a, 2b and 2c, 2d.

In Fig. 1 and Fig. 2, the vertical frames 1a-1d, the top frames 1i-1l and the vertical frames 1e-1g are respectively integrally formed, but they can also be made into separate components and combined by welding or other methods.

Between the outermost vertical frames 1a, 1d, 1e, and 1h of the frame group member 1 and the inner vertical frames 1b, 1c, 1f, and 1g respectively adjacent to them in a parallel state, four zoom mechanisms 2a, 2b, 2c , 2d are connected to each other in an X shape, the lower end side and each connecting portion of each vertical frame 1a-1h are connected to each other to be rotatable, and the upper end side and each connecting portion of each vertical frame 1a-1h are connected to be slidable in the vertical direction.

The outermost frame group members 1, i.e. the longitudinal frames 1a, 1d, 1e, 1h, and the inner frame group members adjacent to them in a parallel state, i.e. the longitudinal frames 1b, 1c, 1f, 1g are kept parallel by the action of the scaling mechanism. In the state, they approach or leave in the direction of mutual approach (inner direction) and the direction of mutual separation (outer direction).

An air supply opening 3 is provided on the top surface, and a dryer mounting frame 4 for mounting or contacting a dryer with a blower function 10 described later is provided between the top frames 1j and 1k around the portion.

In addition, an exhaust opening 5 is provided on a part of the surrounding side of the painting space (the upper part in FIG. 2 ), and an exhaust device mounting frame 6 for installing an exhaust fan and a duct hose is provided on the horizontal frame 1r at the surrounding part. and 1s.

Wheels 7 are provided at the lower ends of the respective vertical frames 1a to 1h, so that they can move freely on the ground or the like.

The above is the structure of the skeleton group member 1 forming the skeleton of the painting space.

Next, the painting booth in the state where the cover member 8 is put on the frame group member 1 will be described with reference to FIG. 5 .

The cover member 8 includes four peripheral sides, namely, a front side 8a, a right side 8b, a left side 8c, a back side 8d, and a top side 8e. The front surface 8a of the cover member 8 is provided with a locking piece (not shown), which allows the object to be painted, such as a car, to enter and exit, and can be lifted upward without falling down.

As the cover member 8, a relatively thick vinyl material is joined or formed by means of cutting, sewing, melting, bonding, riveting, or a zipper. In FIG. 5 , the thick framed rectangular portions at the four corners of the front 8 a and the back 8 d serve as thick opaque auxiliary covers 9 .

Thick skirts 9a are provided at each lower end of the auxiliary cover 9 to seal between the lower end of the cover member 8 and the installation surface so that internal air hardly leaks out.

In addition, since the auxiliary cover 9 is joined with the adjacent cover members 8a and 8b and the cover members 8a and 8c by a zipper, it functions to prevent the inflow of air at the joint portion.

Next, referring to FIG. 3 and FIG. 3 , the effective use of the space of the painting booth according to the present invention will be described. In Figure 3, the painting space is the largest. On the other hand, in FIG. 4, when the outermost vertical frame 1d, the inner vertical frame 1c, the outermost vertical frame 1h, and the inner vertical frame 1g are strongly pressed inward to make them approach each other, The cover member 8 is folded as shown in FIG. 4 while maintaining the mutual parallel state by the parallel movement function of the zoom mechanisms 2b and 2d provided between the vertical frames. As a result, the painting area inside the painting booth is reduced, which reduces the occupied space of the painting booth and further improves space efficiency.

Next, the attachment and detachment function of the dryer with the air blowing function in the painting booth of the present invention will be described with reference to FIGS. 5 and 6 .

The drying machine 10 shown in Fig. 5 is supported by a pair of longitudinal guide rails 100a arranged on the ceiling of another building and a transverse guide rail 100b slidably fitted on the longitudinal guide rails, and is supported on the The up and down direction is locked at the desired position, so that the dryer can move vertically and horizontally along the guide rails, and can also be lifted up and down. The installation of the drying machine 10 on the drying machine mounting frame 4 in the painting room does not necessarily need to be fastened with fastening parts such as bolts and nuts, and a heat-resistant sealing material can also be interposed between the abutting parts of the two. , make the dryer 10 abut against 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 means of a moving frame device.

That is, the frame part 10a of the dryer is movable up and down by the mechanical arm device 11, and is rotatable around a horizontal axis and a vertical axis not shown in the figure near the front end side of the mechanical arm device 11. The wheels 12 at the lower part of the mechanical device 11 are movable on the ground, and the frame 10 a having a reflective area body is in contact with the dryer mounting frame 4 of the air supply opening 3 .

Since the dryer 10 is equipped with a filter for dust removal at the back of the frame body 10a abutting against the air supply opening 3 or at the air suction side behind the air blower, it can effectively prevent the quality of the coating film from being damaged by the air blow. Case.

In addition, the air blower is configured to cool the ventilation space of the frame portion 10a or the required space for blowing air, and the terminal portion of the heating pipe protruding to a gap for blowing the required air, while blowing the air to the coating film. air supply. Therefore, the temperature of the terminal portion can be cooled down to a lower temperature, whereby the heat generation temperature of the heat generation portion can be increased, and the drying time of the coating film can be further shortened.

However, in the present invention, the painting is mainly carried out in the interior of the painting booth (painting booth), but for example, when the outer surface of a part of the car's side door, fender, car trunk, bumper, hood, etc. is damaged Occasionally, etc., the car is parked along the surrounding side of the painting booth (for example, the front 8a), or the cover member of the front 8a is lifted up in the state where the painting booth is moved to the side of the painted surface of the car, and the cover is closed with the cover. The member surrounds the surface to be painted of the automobile, and the painting operation is performed on the side of the paint booth with the surface to be painted exposed in the paint booth.

In this case, since the interior of the painting booth does not require a large space, it is desirable in terms of space efficiency to move the outermost frame inward and fold the cover member in advance as described above.

When the surface to be painted of the automobile is surrounded by the cover member 8, there may be a gap between the automobile and the painting booth. In this case, it is preferable to connect the auxiliary cover member with an adhesive tape, a zipper, or a hook. , to block all the gaps.

The cover member 8 is configured to only lift up a part of the peripheral side such as the front 8a, but it is not limited to this, and other left and right side surfaces 8b, 8c, and back 8d may also be opened. They can be connected to each other with veneer zippers or hooks.

In the painting booth of the present invention configured as described above, for example, the object to be painted is moved into the painting booth, or the painting booth is moved to the object to be painted to prepare for painting.

Next, the dryer 10 and the exhaust fan (not shown) are started to rotate. During painting, the dryer 10 does not energize the heater or supplies a small electric power, so that the inside of the painting booth is ventilated (a so-called push-pull structure).

After the coating is completed, the electric power supplied to the heater of the dryer 10 is set to a predetermined value to strongly dry the coating film. The drying of the coating film differs depending on the coating process, and an appropriate temperature and drying time are set for primer treatment (putty, putty coating, etc.), toning work, surface coating work, etc.

In any drying process, the drying operation is carried out quickly while the object to be painted is placed in the painting booth, so compared with the conventional equipment, the working efficiency can be greatly improved.

The dryer 10 is separated from the air supply opening 3 after the painting operation is completed, and a frame part (hot air discharge part) is arranged near the surface to be painted to directly dry the surface to be painted.

By the way, the capabilities of the conventional standard paint booth and the simplified paint booth of the present invention.

An example of the conventional standard paint booth shape is that the height is 2500mm, the width is 4000mm, and the depth is ^7000mm . 340～430m ³ /min.

In contrast, the shape of the painting booth of the present invention is 2000 mm in height, 2600 mm in width, and 2100 mm in depth.

The air supply fan capacity of the dryer 10 of the present invention is 40 to 44 m ³ /min, and the exhaust fan capacity is 37 to 55 m ³ /min, and there is no difference in ventilation performance compared with the above-mentioned standard paint booth of the prior art. In terms of wind speed, it is generally 0.2-0.4m/min, and the wind speed in the painting room of the present invention is 2-3 times faster than the standard painting room. From the above point of view, it can fully adapt to slow evaporation type paints such as water-based paints, and high boiling point liquid paints, and can exert good effects.

However, the painting room of the present invention is not a fixed type as a workplace for on-site operations, but wheels are installed on the lower part of the skeleton group member. In addition, wheels are also installed for the rack type mechanical arm device supporting the dryer 10. In addition , when the suspension type of the dryer 10 is used, since it can be moved vertically and horizontally by using the guide rail, the painting place and drying place can be freely changed, and the space in the workshop can be effectively used.

In the conventional painting booth, there was sometimes such a problem that the repair vehicle had to be moved to the painting site for surface coating work after the priming treatment process was completed. However, the painting booth of the present invention only needs 1 to 2 blocks. The repair area on the left and right sides of the board can be carried out from primer coating, surface coating to drying in the same place without choosing a place.

This means that it is possible to greatly improve the efficiency of the sheet metal coating operation, and at the same time contribute to a significant cost reduction of equipment related to coating.

In addition, the painting room of the present invention has a structure in which the dryer with the air supply function can move horizontally and vertically, so when painting, the dryer is brought into contact with the air supply opening to make it communicated with the inside of the painting room. , used for ventilation, leave the air supply opening during drying, move to the surface to be coated to be dried, and separate the frame (hot air injection part) with the reflection area of the dryer at a specified distance Installed in front of the surface to be coated, it can be used for drying, which can significantly shorten the hook time. It can also be used for ventilation and drying, which can reduce equipment costs and improve space efficiency.
