JP7572059B2 - Drying/painting table and production method of painted items - Google Patents

Description

The present invention relates to a painting table for painting and drying wood and other materials, and a method for producing painted objects.

Wooden boards such as wood deck flooring deteriorate due to wind and rain, and in some cases may even rot, making it essential to apply an antiseptic paint. To increase durability, it is necessary to apply an antiseptic paint not only to the front but also to the back. Generally, painting is done on finished products. However, as mentioned above, wooden boards such as wood deck flooring need to be thoroughly painted with an antiseptic paint before assembly to protect them from corrosion, and a workbench is used on which to place the boards and other items to be painted (Patent Document 1).

The following explanation will be given using drawings, but the drawings are created for explanatory purposes, and in order to make the explanation easier to understand, some components not necessary for the explanation may not be shown intentionally. Also, some components may be shown intentionally large or small for the explanation, and the drawings are not drawn to an accurate scale.
In the following description, the same reference numerals in different drawings indicate parts having the same functions, and duplicated descriptions in each drawing will be omitted as appropriate.

In this invention, coating materials are not limited to paints and varnishes, but also include any coating material such as preservatives and caulking materials.

[Overall structure of drying/painting stand]
1 is a perspective view of a drying/painting stand 1. The drying/painting stand 1 is composed of a workpiece placement section 11 and a support section 13 that supports the workpiece placement section 11. A plurality of protrusions 12 are attached to the upper surface of the workpiece placement section 11. The workpiece placement section 11 is supported by the support section 13.

[Support part]
The support section 13 supports the workpiece placement section 11, and in the first embodiment, is attached to the workpiece placement section 11 in a non-foldable manner. The support section 13 may be configured to be foldable, which has the advantage of being compact when folded. The support section 13 is not necessarily required. The workpiece placement section 11 may be made wide enough to stand on its own, and appropriate items such as scaffolding at a construction site may be used as the support section 13.

[How to use the drying/painting stand]
2 is an explanatory diagram of an example of use of the drying/painting table 1. An operator prepares a pair of drying/painting tables 1 and places an object 2 (plate material) to be coated on the protrusions 12 of both drying/painting tables 1. The object 2 can be made of any material, such as wood, plastic, metal, etc. The shape of the object 2 is not limited to plates, and can be any shape, such as building materials such as rectangular columns, three-dimensional objects such as box-shaped cover members, or parts of equipment with complex shapes.

The workpiece 2 (plate material) placed on the protrusions 12 has a first surface (front surface) 21 painted with paint. Then, before the painted paint dries, it is flipped over as shown by the arrow, and the second surface (back surface) 22 is painted. The paint on the first surface (front surface) 21 is not dry, but since it is supported by the protrusions 12, the effect on the painted surface can be kept to a minimum. It is desirable for the tip of the protrusions 12 to be sharp like a nail in order to reduce the effect on the painted surface. After the first surface (front surface) 21 and second surface (back surface) 22 have been painted, the workpiece 2 (plate material) is left, if necessary, until the paint dries.

After drying, small marks remain on the first surface (front surface) 21 where the protrusions 12 came into contact, indicating that the coating has thinned. If necessary, workers who are concerned about these marks can apply a topcoat only to the areas with the small marks.

The above examples of use can be summarized as follows as a method for producing coated articles.
(First step) A step of preparing the drying/coating table 1 of the present invention.
(Second step) A step of placing the workpiece 2 on the protrusion 12 provided on the workpiece placement portion 11 with the first surface (front surface) 21 of the workpiece 2 facing upward.
(Third step) A step of coating the first surface (front surface) 21 of the workpiece 2 .
(Fourth step) In the fourth step, before the paint dries, the workpiece 2 is rotated so that the second surface (rear surface) 22 of the workpiece 2 faces up and the first surface (front surface) 21 is placed on the protrusions 12.
(Fifth Step) The fifth step is to paint the second surface (rear surface) 22 of the workpiece 2 with paint.
A method for producing a coated object comprising at least the steps of:
If necessary,
(Sixth step) A step of drying the paint while the workpiece 2 is placed on the workpiece placement section 11 .
may be added.

When the workpiece 2 is a rectangular column, the worker paints four surfaces in the same manner, including the first surface (front surface) 21, the second surface (rear surface) 22, and both side surfaces. In this way, the worker can efficiently paint the workpiece 2.
Since the drying/painting table 1 in Example 1 is configured as a pair, even long plate materials (workpieces 2) can be accommodated by adjusting the distance between the two drying/painting tables 1, making it even easier to use.

In Example 1, the workpiece 2 (plate material) which is a building material is used, but it can also be used for small workpieces, such as parts, by devising the shape of the workpiece mounting portion 11 and the arrangement of the protrusions 12. Figure 3 is a perspective view of the drying/painting table 1 for painting parts.
In order to accommodate parts of various shapes, the protrusions 12 are attached in multiple rows to the upper surface of the workpiece mounting portion 11. The protrusions 12 in the second embodiment are pyramidal in shape and have sharply pointed tips. This minimizes the area that comes into contact with the workpiece 2. If the workpiece 2 is easily scratched, the tips of the protrusions 12 may be rounded.

(Shape of protrusion)
The protrusions 12 serve to support the weight of the workpiece 2. If the workpiece 2 is heavy, it is preferable to support it with a large number of protrusions 12. Furthermore, if the surface of the workpiece 2 is made of a material that is easily scratched, it is preferable that the tips of the protrusions 12 are rounded.

As described above, the optimum tip of the projection 12 may vary depending on the weight of the workpiece 2 and its susceptibility to damage. Therefore, the worker can use a cap material 3 to be attached to the tip of the projection 12. Fig. 4 is an explanatory diagram of the cap material, and when the workpiece 2 is likely to be scratched, the cap material 3 with a rounded tip and made of a soft material (e.g., synthetic resin) can be fitted to the tip of the projection 12, so that the workpiece 2 can be placed on the workpiece placement unit 11 under optimal conditions. The cap material 3 can also be made to have a pointed tip that is sharper than the projection 12. A wide variety of cap material materials are available, from soft ones like rubber to hard ones.
In this way, by providing various variations in the cap material 3, it can be adapted to any type of object 2 to be coated.

(paint)
As mentioned above, the coating material is not limited to paint or varnish, but may be any chemical agent, so long as it is applied to the object 2. The drying/coating table 1 of the present invention can also be applied to the object 2 in which there are gaps between the plate materials (objects 2 to be coated), such as a panel-shaped member in which multiple plate materials (objects 2 to be coated) are arranged and secured with a backing material.
For example, the drying/painting table 1 of the first or second embodiment can be used for filling gaps between plate materials (objects 2 to be coated) with a caulking material. The paint in the present invention includes caulking materials.

(test)
A commercially available waterproof silicone caulking material was diluted two-fold with a solvent and used as the paint. The paint was applied to both sides of a wooden deck floor material as the object to be coated 2 using a drying and coating table 1, and both sides of the object to be coated 2 could be efficiently coated.
It was also confirmed that the coated object 2 had extremely high water resistance.

Furthermore, the above-mentioned embodiments and possible variations can be combined by reusing each other's technologies, so long as there are no particular contradictions or problems in their purpose and configuration, etc.
