Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an automobile painting frame that can be easily installed in a small space.

(Conventional technology) When painting automobiles at automobile repair shops, etc., spray painting is generally done using a spray gun, but paint errors and harmful solvents are scattered, deteriorating the working environment in the factory and the surrounding living environment. To ensure this, painting is usually done in a closed room.

Conventionally, there is an apparatus for painting automobiles used for such purposes as disclosed in, for example, Japanese Utility Model Publication No. 46384/1984.

In other words, this publication states that an exhaust groove is formed on the floor of a paint drying room whose periphery is hermetically divided with heat insulating panels, and hot air or intake air supplied from outside is guided to an exhaust cleaning device through the groove. An automobile paint drying room is shown in which paint is discharged outside using a blower.

(Problem that the invention aims to solve) However, with such conventional so-called underfloor pit type, it may be impossible to excavate the pit due to the architectural structure of the repair shop, and even if it is possible, the construction period may be short. For a long time, there have been problems such as increased construction costs.

On the other hand, the other methods mentioned above include the so-called trestle type and suction type, but in the case of the former, the construction period is shorter than the pit type, but the work floor is slightly higher than the factory floor. Since it is usually made of iron, the construction cost is about the same as the pit method, and because of its one-piece structure, it is not easy to replace the frame.
There are problems such as maintenance becoming extremely difficult.

In the latter case, the paint mist is sucked in from a duct installed at the rear or side of the work bay. Most of what is inhaled is floating mist, and heavy mist falls onto the work floor and accumulates. Attach,
There is a problem of staining the work floor.

The purpose of the present invention is to solve these conventional problems and provide a frame for car painting that can be manufactured at low cost with a simple configuration and that can be easily installed using a small space. .

(Means for Solving the Problems) Therefore, the automobile painting stand of the present invention includes a pair of side ducts that can be installed on the floor and a cross duct that communicates with these ducts, and a plurality of An intake frame having an intake port formed therein is removably provided so that a vehicle can be mounted on the frame, a filter is accommodated in the cross duct, and a ventilation port communicating with the intake duct is formed in the duct. By using a simple configuration of a duct structure that also serves as a pedestal without requiring pit excavation or a large-scale pedestal structure, it can be manufactured at low cost and can be easily installed using a small space. It is characterized by what it did.

(Embodiment) Hereinafter, an embodiment of the present invention will be explained with reference to the drawings. In Figs. It is appropriated to The work bay 2 is constructed by not partitioning the surrounding area with a partition wall, by partitioning the surrounding area by a simple partition wall 3 such as a vinyl sheet, or by installing it directly in the painting room. A painting stand 4 is installed.

The painting frame 4 includes a pair of entry steps 6, 6 for boarding the automobile 5, and side ducts 7, 7 removably hooked to the rear ends of these steps 6, 6 by appropriate means. It is composed of a cross duct 8 which communicates with these ducts 7, 7 and is connected to its rear end via bolts, nuts, etc.

Of these, the boarding step 6 has a wide inclined surface 6a extending downward and downward in the front, and side pieces 9, 9 which can be installed on the floor surface 1 are formed on the sides thereof.

The side ducts 7, 7 are constructed of elongated frames having a substantially isosceles hollow cross section, and as shown in FIG. , 11 are arranged facing each other in a substantially V-shape, the front ends of which are closed with appropriate members, and the rear ends are open, and a bottom plate 12 is fixed between the inner lower portions of these frames 11, 11.

A supporting metal fitting 13 having an L-shaped cross section is fixed to the inner upper part of the duct frame 11, and these metal fittings 1
A plurality of intake frames 14, 15, 1 on 3, 13
6 is removably housed.

As shown in FIG.
A plurality of mounting frames 18 made of, for example, striped steel plates bent in a U-shape are installed between 7 and 17, and the front and rear wheels 19 and 20 of the automobile 5 can be mounted on these frames 18. frame 18,
Elongated air intake ports 21, 22, and 23 are formed between the holes 18.

These intake ports 21, 22, and 23 have different opening widths for each intake frame 14, 15, and 16, and the opening widths are gradually increased in the order of intake frames that are spaced apart from an intake fan, which will be described later. That is, the opening width of the intake port 21 that is farthest from the fan is the largest, and that of the intake port 23 is the smallest.

In this case, although it is possible to have the intake frame as a long unitary structure, it is preferable to configure it as in the embodiment, which is convenient for cleaning and handling.

In addition, the height of the duct frame 11 gradually increases toward the rear as shown in FIG. suppress corners,
The length of step 6 is intended to be shortened.

On the other hand, the cross duct 8 consists of an elongated box having the same length as the outer width of the side ducts 7, 7, and among the duct frame 24 and side frames 25 forming the peripheral wall, the elongated duct frame 24,
A support plate 26 is fixed to the upper inner side of the plate 24, a cover plate 27 is removably housed on the plate 26, and a bottom plate 28 is fixed below the plate 26.

The duct frame 24 located at the front is provided with a pair of ventilation holes (not shown) communicating with the side duct 7, and the duct frame 24 located at the rear is provided with a horizontally elongated intake port 29. One end of an intake duct 30 is connected to the intake port 29 .

The other end of the intake duct 30 extends outside the work bay 2 through the partition wall 3, and an intake fan 31 is provided at the open end thereof. In the figure, 32 is a filter housed in the cross duct 8.

FIGS. 8 and 9 show other embodiments of the present invention, in which the same reference numerals are given to parts corresponding to those of the embodiment described above. That is, in this embodiment, a substantially box-shaped bridging duct 33 that communicates with the side ducts 7, 7 is connected between the front ends of the side ducts 7, 7 via bolts and nuts, thereby increasing absorption of paint mist and increasing the efficiency of the duct. 7,7 is characterized by its stability.

The cross-linked duct 33 has a substantially wedge-shaped front view as shown in FIG. An intake frame 35 having an intake port 34 similar to that of the intake frame 14 is removably housed in the upper opening thereof.

(Function) When installing the automobile mount constructed in this way, the work bay 2 is partitioned by partitioning the periphery of a desired position on the flat work floor surface 1 with a partition wall 3, for example.

Then, a pair of side ducts 7, 7 are arranged parallel to each other approximately in the middle of the work bay 2, and the steps 6, 6 are latched onto the front ends, that is, the closed ends, of these ducts 7, 7. That is, the ventilation holes (not shown) of the cross duct 8 are positioned at the open ends, the ventilation holes (not shown) of these ducts 8 are positioned, and the ducts 7 and 8 are connected with bolts, nuts, etc.

In this way, boarding step 6 and each duct 7, 8
After connecting the support plates 1 of the side ducts 7, 7
3, 13, from the front the intake frame 14, 1
5 and 16, a filter 32 is installed in the cross duct 8, and a cover plate 27 is installed on the support plate 26 thereof.

Further, one end of an intake duct 30 is connected to the intake port 29 of the cross duct 8, the other end is extended to the outside of the work bay 2 through the partition wall 3, and an intake fan 31 is installed at the outside opening of the duct 30. do it.

In this way, when installing the above-mentioned pedestal, the existing work floor 1 can be used as is, and the step 6 and the ducts 7 and 8, which also serve as the pedestal, can be assembled and installed by climbing onto it. It can be installed in a short period of time, and unlike conventional methods, it does not require excavation of pits.
There is no need for a large-scale stand with an integrated structure.

Moreover, the work bay 2 is configured to have a small space that allows a worker to pass outside each of the ducts 7 and 8, and the side duct 7 is tilted forward and downward, so that the length of the boarding step 6 is small. By shortening the space, the above-mentioned space reduction is promoted, and the use of the work floor 1 is reduced.

In addition, for the side duct 7, an intake frame 1 that also serves as a mounting plate for the automobile 5 and an intake member is provided.
Since only parts 4, 15, and 16 need to be attached, the number of parts is reduced accordingly, and the structure and assembly are simpler than the conventional structure in which these parts are configured separately.

Furthermore, since the filter 32 is housed in the cross duct 8 which also serves as a filter box, there is no need for a large filter box like in the past, and the number of separate parts is therefore reduced, and the structure is simplified and The use of floor space can be reduced.

In addition, a simple partition panel is constructed above the work bay 2 to close off the upper opening, and an air supply fan is attached to the panel to push the paint mist downward, that is, toward the painting stand 4 side. That is desirable.

In the automobile frame assembled in this way, the side duct 7 is connected to each intake frame 14, 1.
It communicates with the inside through the intake ports 21, 22, and 23 of the ducts 5 and 16, and communicates with the cross duct 8 through its rear opening and the ventilation hole (not shown). It communicates with the outside of the work bay 2 via an intake port 29 and a ventilation duct 30.

When actually painting the entire circumferential surface of a car using such a stand, the car 5 must be loaded into the work bay 2, and then climbed onto the side ducts 7, 7 via the boarding steps 6, 6. , move the intake frames 14, 15, and 16 rearward, and move the front wheels 1
9 and 19 move to the rear ends of the side ducts 7 and 7, the automobile 5 is stopped.

In this case, when painting only a part of the car 5, such as the bonnet or trunk panel, the painting position is positioned as close to the center of the side duct 7 in the length direction as possible to prevent the paint mist from spreading unevenly. It is desirable to increase its inhalation efficiency.

Then, by closing the entrance side of the work bay 2 and driving the air supply fan (not shown) and the intake fan 31, a series of preparatory work is completed. That is, when the fan is driven, air is supplied into the work bay 2 through the air supply fan, and on the other hand, the air inside the work bay 2 is sucked in through the side ducts 7, 7 by the intake fan 31. This is discharged to the outside of the work bay 2 via the cross duct 8 and the intake duct 30.

Under these circumstances, when painting is performed using a spray gun, for example, paint mist, solvent, etc. are dispersed into the work bay 2, and this is forcibly moved downward via the air supply fan, causing each Intake port 21, 2
2, 23 and the side duct 7 from the intake hole 10,
It is sucked into 7.

In this case, the opening widths of the intake ports 21, 22, and 23 are such that the opening width of the intake port 21 that is farthest from the intake fan 31 is the largest, and that of the intake port 23 is the smallest. The intake area is adjusted accordingly, so each intake frame 1
The intake air amount at 4, 15, and 16 becomes almost uniform,
Uniform air intake is performed over the entire area of the side ducts 7, 7.

Moreover, the intake air is supplied to the intake holes 10 of the duct frames 11, 11 extending laterally from the ducts 7, 7.
This also improves the efficiency of sucking in paint mist.

In this way, the paint mist and the like sucked into the side ducts 7, 7 move rearward inside the ducts 7, 7, and are guided into the cross duct 8 through the ventilation holes from the open ends of the ducts 7, 7, and into the cross duct 8. Dirt and dust are removed by the filter 32 installed at the air intake port 2.
9 to the intake duct 30 and is discharged to the outside of the work bay 2.

After painting, the drive of the fan is stopped, the state is maintained for a predetermined period of time, and the car 5 is heated after it is dried.
is removed from work bay 2.

On the other hand, as a result of such painting, paint errors adhere to the work floor 1, boarding steps 6, 6, and ducts 7, 8, which require cleaning. 16, cover plate 27, and filter 32 can be removed individually, making it possible to wash them with water. Furthermore, if necessary, the steps 6, 6 and ducts 7, 8 can be removed and carried out to the outside of the work bay 2. , this type of cleaning work can be performed easily and precisely.

Even with such cleaning, since the bottom plates 12 and 28 of both ducts 7 and 8 are constructed at a height from the floor surface 1, they will not rust due to adhesion of water.

(Effects of the invention) As described above, the car painting stand of the present invention is equipped with a pair of side ducts that can be installed on the floor, a cross duct that communicates with these ducts, and a plurality of air intake ports at the top of the side ducts. A removable intake frame is provided so that a car can be mounted on the frame, and a filter is accommodated in the cross duct and an intake port communicating with the intake duct is formed in the duct. By using a duct structure that also serves as a pedestal without requiring excavation or constructing a large-scale pedestal, it can be manufactured with a simple structure and at low cost.

Therefore, unlike conventional devices of this type, there are no problems such as separate installation of the vehicle mounting plate and intake member, or the need for a dedicated filter box, and the number of parts can be reduced accordingly. It has a practical effect and can be easily installed by utilizing space.
