DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a coating apparatus.

[0002]

2. Description of the Related Art Conventionally, in the field of house construction, a panel construction method for constructing a floor, a ceiling, an outer wall, or a partition wall of each room with panel materials of a predetermined area manufactured in advance in a factory or the like in order to shorten a construction period. It's being used. In such a panel construction method, a panel material manufactured by attaching a face material such as plywood to a surface of a square frame-shaped base frame made of a wooden square material is used. Then, when manufacturing the panel material, a liquid preservative is applied in advance to the square material constituting the base frame by a coating device in order to prevent corrosion of the square material.

[0003] A conventional coating apparatus is provided with a pair of coating rollers vertically comprising a core having a vertical rotating shaft and a sponge-like impregnating portion covering the outer peripheral surface of the core. . The application roller is configured such that the liquid preservative injected into the core is impregnated into the impregnated portion, and the liquid preservative is oozed out of the surface of the impregnated portion. A liquid preservative was applied by passing through.

[0004]

However, with a pair of application rollers, the liquid preservative can be applied only to two opposing surfaces of the rectangular material at a time, so that the liquid preservative is applied to the four application surfaces of the rectangular material. In order to apply the agent, it is necessary to pass the timber twice between the application rollers, which is time-consuming and inefficient, and causes some unevenness between the upper end and the lower end of the application roller. there were. It is also conceivable to provide a pair of horizontally installed application rollers in addition to the application roller that is set up vertically, and apply the liquid preservative to the four surfaces of the timber at a time. If provided horizontally, the liquid preservative inside the core will accumulate below due to gravity, so the amount of liquid preservative to be applied to the timber is greater on the horizontal top surface than on the vertical side, There is a problem that the number of lower surfaces is reduced, the application amount is not uniform on the four surfaces of the square bar, and repair work is required. Such a problem is not limited to a liquid preservative, but also applies to a case where various coating agents such as an adhesive are applied.

An object of the present invention is to provide a coating apparatus capable of uniformly and efficiently applying a coating agent to each surface of a substrate to be coated.

[0006]

The present invention will be described with reference to the drawings. A core 41B having a rotating shaft 41A and an outer peripheral surface 41F of the core are brought into contact with an object to be coated (for example, the square member 10). An application device 23 including an application roller 41 including a sponge-like impregnating portion 41C.
And the rotating shaft of the application roller is provided in a direction inclined with respect to the horizontal direction.

In the present invention, since a plurality of application rollers are provided and brought into contact with the respective application surfaces of the object to be applied, the rotation axis of the application roller is provided in a direction inclined with respect to the horizontal direction. In comparison with the conventional case where only a vertically arranged application roller is provided or the case where a vertically installed application roller and a horizontally installed application roller are provided, the coating agent in each application roller is The difference in the bias of the coating material is reduced, and the amount of the coating material applied to the coating object is not more uneven than in the past, so that the coating agent is uniformly and efficiently applied to each coating surface of the coating object. Become.

The rotation axis of each coating roller does not necessarily have to have the same inclination angle with respect to the horizontal direction, but it is preferable that the rotation axis be inclined at the same inclination angle with respect to the horizontal direction. If the rotation axis of each application roller is inclined at the same inclination angle with respect to the horizontal direction, there is no unevenness even when comparing the application amount of each application surface of the application object. The coating agent is evenly applied to the application surface.

Further, the number of application rollers may be smaller or larger than the number of application surfaces of the object, but if possible, the number of application rollers is equal to the number corresponding to the number of application surfaces of the object. Preferably, it is provided. If the application rollers are provided in a number corresponding to the number of application surfaces of the application object, the operation of applying the application agent can be performed at one time, so that the operation efficiency is further improved.

The object to be coated is a square member 10, and the rotation axis of each coating roller is inclined at 45 degrees with respect to the horizontal direction, and the rotation of each coating roller is brought into contact with an adjacent surface of the square member. Preferably the axes are orthogonal. The timber is
Normally, the adjacent side surfaces are crossed at 90 degrees to each other, so that the rotation axis of each application roller is inclined at 45 degrees, and the rotation axis of each application roller that is in contact with the adjacent surface of the square bar is orthogonal, Since the inclination angles of the four application rollers that are in contact with the four application surfaces of the timber are the same, even when comparing the application amounts of the surfaces, there is no unevenness, and the application agent is even on the four application surfaces. It will be applied to.

Further, it is desirable that a total of four application rollers be provided, one pair for each of two opposing surfaces of the square bar. If a total of four application rollers are provided, one pair for each of the two opposing surfaces of the square bar, the coating agent will be applied to the four surfaces, which are the surfaces to which the square bar is applied, in one application operation. In addition, the work efficiency of the coating device is improved, and various square members having different widths and heights can be easily coped with by adjusting the size between each pair of coating rollers. In addition, the pair of application rollers sandwich the square, and even when each application roller is pressed against the square, the force can be received by the application roller arranged at the opposing position. The roller can reliably contact the square bar.

Further, it is desirable that the square member is supported by a support member 21 having a substantially V-shaped cross section. If the square member is supported by a support member having a substantially V-shaped cross section, each surface of the square member is guided at a predetermined inclination angle with respect to the horizontal direction according to the angle of the rotation axis of the application roller. It is not necessary to adjust the inclination angle of each of the surfaces to be coated with respect to the horizontal plane each time, which also improves the working efficiency.

As shown in FIG. 3, each application roller 41 has
A core 41B having a rotating shaft 41A, and a sponge-like felt impregnated portion 4 covering an outer peripheral surface 41F of the core 41B.
1C. In the application roller 41, the liquid preservative supplied through a hose 41D connected to the rotating shaft 41A flows into the inside of the core 41B from the upper end of the rotating shaft 41A, and is provided over substantially the entire outer peripheral surface 41F.

The lower end of the application roller 41 is covered with a bolt 41G, and the liquid in the core 41B can be discharged by removing the bolt 41G.

Each of the application rollers 41 of the application sections 23A and 23B
The rotation shaft 41A of the coating roller 41 is orthogonal to the feed direction of the rectangular bar 10 and is inclined at 45 degrees with respect to the horizontal direction, and is in contact with the application surface 11 adjacent to the rectangular bar 10. It is orthogonal to the rotation axis 41A. Thereby, the application roller 41 of each of the application units 23A and 23B is
The four coated surfaces 11 of the timber 10 are brought into contact with each other,
It is configured such that a liquid preservative is applied to four application surfaces 11 at a time by feeding the rectangular material 10 into 3A and 23B.

The coating process in the coating line 20 will be described below. First, when sending the timber 10,
The square member 10 is placed on the support member 21, and the inclination angle of each surface 11 to be coated of the square member 10 with respect to the horizontal direction is set to 45 degrees. Then, the rectangular material 10 is fed into the coating device 23 by the rotating member 25 rotating by the motor 27 of the feeding device 22 and the rotation assisting member 26 provided on the opposite side of the rotating member 25. A liquid preservative is applied to one of the two surfaces to be applied 11 of the two sets of opposing surfaces of the square bar 10 at the application unit 23A of the application device 23, and the application unit 23B
Then, a liquid preservative is applied to the other two application surfaces 11. The square material 10 in which the liquid preservative is applied to the four application surfaces 11 is sent to the delivery device 24 by the rotation of the application roller 41, and then the motor 27 of the delivery device 24.
The rotation member 25 is rotated by the rotation member 25 and the rotation auxiliary member 26 provided on the opposite side of the rotation member 25, and is sent to the next step while being supported by the support member 21. In this manner, a liquid preservative is applied to the square bar 10.

According to this embodiment, the following effects can be obtained. Since the rotation axis 41A of each of the application rollers 41 is provided in a direction inclined at 45 degrees with respect to the horizontal direction, the bias of the preservative in each of the application rollers 41 due to gravity becomes substantially the same. The preservative can be evenly and efficiently applied to the four surfaces 11 to be applied. Accordingly, it is not necessary to manually apply a preservative to the surface 11 to be coated of the square member 10 and repair the same, and the efficiency of the operation of applying the preservative to the square member 10 can be improved.

Further, a pair of application rollers 41 is provided for each of the two opposing surfaces 11 of
Since the individual pieces are provided, the operation of applying the liquid preservative to the application surface 11 of the square bar 10 can be performed once, and the operation efficiency of the application line 20 can be improved. In addition, by adjusting the size between the application rollers 41 provided in pairs, various square materials 10 having different widths and heights can be adjusted.
Can be easily handled. Further, a pair of application rollers 4
1, the square bars 10 are sandwiched, and even when each of the application rollers 41 is pressed against the square bars 10, the force can be received by the application rollers 41 arranged at the opposing positions. 41 can be reliably brought into contact with the square bar 10.

Further, since the rotating shaft 41A of each application roller 41 is provided in a direction orthogonal to the feed direction of the square bar 10, the rotation direction of each application roller 41 and the feed direction of the square bar 10 coincide with each other. The roller 41 can be smoothly rotated, and the square material 10 can be easily sent to the sending device 24 side.

Further, if the square member 10 is supported by the support member 21 having a substantially V-shaped cross section, each coated surface 11 of the square member 10 is guided so as to have a predetermined inclination angle (45 degrees) with respect to the horizontal direction. Therefore, it is not necessary to adjust the angle of inclination of each of the surfaces 11 to be coated of the square bar 10 with respect to the horizontal plane each time, and the working efficiency can be improved from this point as well.

Furthermore, by making the impregnated portion 41C made of a strong and strong stiff felt, the abrasion resistance of the impregnated portion 41C is improved, and even if the shape is deformed by using for a long time, the original shape is changed over time. In this case, the impregnated portion 41C removed by the deformation can be reused.

It should be noted that the present invention is not limited to the above-described embodiment, but includes other configurations capable of achieving the object of the present invention, and the following modifications are also included in the present invention.
For example, in the above-described embodiment, the impregnated portion 41C is made of felt. However, the present invention is not limited to this. For example, the impregnated portion 41C may be made of polyurethane and have many open cells.

The support member 21 is not limited to a substantially V-shaped cross section, but may be formed in, for example, a substantially U-shaped cross section or a substantially trapezoidal cross section. That is, an arbitrary shape may be selected as long as the square bar 10 can be fixed at a predetermined angle with respect to the horizontal direction in a direction orthogonal to the longitudinal direction.

Further, in the above-described embodiment, the square member 10 is supported by the support member 21, but the support member 21 is not necessarily required. In this case, the square material 10 may be sent to the coating device 23 while supporting the square material 10 with the hand of the operator.
However, it is preferable that the square member 10 be supported by the support member 21, for example, in that the inclination angle of the square surface 10 with respect to the horizontal direction of the coating surface 11 can be easily and accurately adjusted.

Further, in the above-described embodiment, the rotating shaft 41A of each coating roller 41 is inclined at 45 degrees with respect to the horizontal direction to have the same inclination angle.
Is changed, and the rotation axis 41A of each application roller 41 is changed.
May be configured to be inclined at different inclination angles with respect to the horizontal direction. In this case, the inclination angle of the rotation axis 41A of each application roller 41 with respect to the horizontal plane is close to 0 degrees or 9 degrees.
When the angle is close to 0 degrees, the difference in the bias of the coating agent becomes large as in the conventional case.
The range may be 0 to 60 degrees, preferably 40 to 50 degrees.

For a member having a rhombic cross section or a triangular cross section other than the square member 10, for example, the rotating shaft 41A of the coating roller 41 is inclined at an appropriate angle in accordance with the shape of the object to be coated. Just do it. In this case, each application roller 41
Of the rotating shaft 41A cannot be inclined at the same inclination angle with respect to the horizontal direction.
What is necessary is just to comprise so that the difference of the inclination angle of A may become as small as possible.

That is, the inclination angle of the rotating shaft 41A with respect to the horizontal direction of each coating roller 41 is
The difference in the amount of the coating agent in the first impregnation section 41C is small, and the difference in the coating amount between the coating rollers 41 is also small, so that the angle at which the coating agent can be uniformly applied to each of the surfaces to be coated of the object to be coated. It should just be set according to the object to be coated.

In the above embodiment, the application roller 41
Although a total of four pairs are provided for each of two opposing surfaces 11 to be applied to the bar 10, the pairs need not be provided. For example, the application roller 41 may be positioned in the feed direction of the bar 10. The application rollers 41 may be arranged at different different positions, respectively, or the four application rollers 41 may be arranged at the same position in the feed direction of the square bar 10.

Further, in the above embodiment, the application roller 4
The number 1 is provided corresponding to the four surfaces 11 to be coated of the square bar 10, but is not limited thereto, and may be smaller than the number of the surfaces to be coated. In this case, it is necessary to send the object to the application device 23 a plurality of times or to provide a plurality of application devices 23.
By inclining 1A, the unevenness of the surface to be coated can be reduced, and the repair work becomes unnecessary, so that a decrease in workability can be prevented. In the case where the coating agent is applied twice, the number of application rollers 41 may be greater than the number of application surfaces.

The coating roller 41 includes a core 41.
Not limited to those in which the coating agent is put inside B, for example,
A coating agent may be directly applied to the impregnating section 41C. Further, the application roller 41 is not limited to the shape of the above-described embodiment, and includes a core 41B having a rotating shaft 41A, and a sponge-like impregnated portion 41C that covers the outer peripheral surface 41F of the core 41B and contacts the square member 10. May be selected as appropriate in accordance with the object to be coated.

In the above embodiment, a preservative is used as a coating agent. However, the present invention is not limited to this. For example, a primer, an adhesive, a sealer, a paint, or the like may be used in addition to the preservative. Can be.

Further, in the above embodiment, the coating device 23
