Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bus design painting method in which the same characters, figures, etc. can be drawn on the surface of the bodies of different buses in the same manner.

[0002]

2. Description of the Related Art Generally, the design of characters, figures, etc. drawn on the surface of a vehicle body of a bus is different for each user, and the number of orders at one time is not so large. For this reason, when painting characters and figures on the surface of a bus body, at present, first create a design original image to be drawn on the surface of the vehicle body, and then based on this, use scales etc. on the surface of the vehicle body one by one. I used to draw a reference line or outline with a pencil, and then taping to determine the paint color range, and then paint.

[0003]

As described above, in the conventional painting method, characters and figures are sculpted on the surface of the vehicle body one by one based on the original design image, so that the vehicle body is injured. It often happens that the quality of each product is different. This is particularly noticeable when curves and the like are mixed, and is the same even when the operators are different. For this reason, there is a problem in that the quality of the work is not stable, and that it takes a lot of time to work, resulting in poor productivity and high cost.

The present invention has been made in view of the above problems, and its purpose is to design a bus in which the same characters, figures, and the like can be simply and similarly drawn on the vehicle body surfaces of different buses. To provide a painting method.

[0005]

In order to achieve the above object, a bus design painting method according to the present invention draws characters, figures, etc. on the surface of a vehicle body of a bus. While creating an original image corresponding to a figure or the like, the original image is transferred onto a film, and the characters and figures transferred onto the film are projected onto the surface of the vehicle body,
The characters / figures, etc. are designed on the surface of the vehicle body by tracing the projected characters / figures.

[0006]

According to this method, the original image such as characters and figures drawn on the surface of the vehicle body can be easily drawn on a small paper or the like by using an automatic drawing machine or the like. Then, this original image is transferred onto, for example, a film for an overhead projector by an electronic copying machine or the like, projected onto the vehicle body surface by the overhead projector, and the projected characters / figures are directly or taping-coated. If you paint after deciding the color range, you can easily design paint the same decided letters and figures. Moreover, since the same original image is projected in the same way on different vehicle body surfaces, there is no variation in the finished design accuracy. Therefore, it is possible to easily draw from the creation of original images such as characters and figures drawn on the vehicle body surface to the work of painting on the vehicle body surface, and to draw any number of them in the same way.

[0007]

Embodiments of the present invention will be described in detail below with reference to the drawings. FIG. 1 conceptually shows a coating process according to the method for designing and painting a bus according to the present invention, and FIGS. 2 to 4 conceptually show a main part configuration in the design coating process.

First, the construction of the main part in the design painting process will be described with reference to FIGS. 2 to 4. On the left and right sides of the passage through which the bus 1 in which characters, figures, etc. are drawn on the surface of the vehicle body, are respectively installed stand tables. The projectors 3, which are, for example, overhead projectors (commonly referred to as “OHPs”) installed on the two 2, are scattered along the passage, three projectors on each side, as indicated by reference numerals 3A, 3B, and 3C. . In addition, each projector 3 is capable of projecting toward the vehicle body surface 11 of the bus 1. Then, as shown in FIG. 3, the central projector 3B projects the corresponding design in the area D of the vehicle body surface 11 on the left and right side surfaces, and the front projector 3A also projects on the area E of the vehicle body surface 11 on the left and right side surfaces. The projector 3C on the rear side projects the corresponding design, and also projects the design corresponding to the region F of the vehicle body surface 11 on the left and right side surfaces.
The projectors (3A, 3B, 3C) can be used to project all images that are the design of the vehicle body surface 11 on the left and right side surfaces. The number of the projectors 3 is arbitrarily set depending on the front and rear lengths of the vehicle body surface 11, and the design image to be projected is separately prepared for each projector 3 and set. Further, the height position of each projector 3 is adjusted every time the height of the vehicle body is different, and the appropriate position is selected.

Next, the design painting process will be described with reference to FIG. 1 together with the layout diagrams shown in FIGS. First,
Prior to painting, the original image designed on the vehicle body surface 11 is projected on each of the projectors 3A, 3A using an automatic drafting machine (CAD) or the like.
It is created for each design corresponding to B and 3C (step S1). In this case, the original image size is about one-seventeenth of the size of characters, figures, etc. actually drawn on the vehicle body surface 11. Next, each original image is transferred onto the film (step S2). In this embodiment, the image is transferred onto a film for an overhead projector (commonly called "OHP film") by using an electronic copying machine. Next, the film produced in step S2 is processed by the corresponding projector 3A,
3B, 3C are set respectively, and characters / figures on the film are projected by the projectors 3A, 3B, 3C toward the bus 1 which is conveyed for painting and set at a predetermined position. The character / figure is projected on the screen (step S3). Further, the characters / figures projected from each of the projectors 3A, 3B, 3C are aligned, and the characters / figures are aligned with the vehicle body surface 11. Then, when the alignment work in step S3 is completed, the necessary parts on the vehicle body surface 11 are taped (step S4), and then the characters and figures on the painted vehicle body surface 11 are painted (step S5). After that, it is dried (step S
Completed with 6). The taping may be performed as needed. If necessary, the characters / graphics projected on the vehicle body surface 11 may be scribed only, and taping and painting may be performed elsewhere. Further, the front and rear surfaces of the body of the bus 1 can be similarly processed at another place or the same place.

Therefore, in this way, the vehicle body surface 11
According to the method of designing characters, figures, etc., the original drawing of characters, figures, etc. drawn on the surface of the vehicle body can be easily drawn on a small paper or the like by using an automatic drawing machine or the like. Then, this original image is transferred onto a film for an overhead projector by an electronic copying machine, and is projected onto the vehicle body surface 11 by an overhead projector as the projectors 3A, 3B, 3C, and the projected characters / figure shape. If you paint directly or taping after deciding the paint color range, you can easily design paint the decided characters and figures, and the same original image will be projected on different car body surfaces in the same way. , There is no variation in the finished design accuracy. Therefore, it is possible to easily draw from the creation of original images such as characters and figures to be drawn on the vehicle body surface 11 to the work of painting on the vehicle body surface 11 and also to draw any number of them in the same manner. Further, the projectors 3A, 3B, 3C can be easily set, and the leveling of the vehicle body etc. can be performed by the projectors 3A, 3B,
Since it can be adjusted with the OHP film on the 3C side, almost no additional equipment is required. Further, the original design image can be saved on a floppy disk or the like, which makes the storage easy.

In the above embodiment, the structure using the overhead projector as the projector 3 is disclosed.
The projector is not limited to the overhead projector, and may be a slide projector, a video projector, or the like. However, when the overhead projector is used, there is an advantage that the film can be easily made by an electronic copying machine or the like.

[0012]

As described above, according to the design painting method for a bus according to the present invention, the original images such as characters and figures drawn on the surface of the vehicle body can be easily printed on a small paper sheet by using an automatic drawing machine or the like. You can draw. Then, this original image is transferred onto, for example, a film for an overhead projector by an electronic copying machine or the like, projected onto the surface of the vehicle body by the overhead projector, and the projected character / figure shape is directly or taped to paint a color. By painting after deciding the range, you can easily design paint the decided characters and figures, and since the same original image is projected on different vehicle surfaces in the same way, there will be variations in the finished design accuracy. It will never happen. Therefore, it is possible to easily draw from the creation of original images such as characters and figures drawn on the vehicle body surface to the work of painting on the vehicle body surface, and to draw any number of them in the same way. As a result, the design accuracy is stable and the appearance is improved, and the working time can be shortened and the cost can be reduced to provide the product at a low cost.
