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 each including a core having a rotating shaft and a sponge-like impregnating portion covering the outer peripheral surface of the core. The application roller is such that the liquid preservative injected into the core flows out of the plurality of round holes provided over substantially the entire outer peripheral surface of the core and is impregnated into the impregnated portion, and the liquid preservative is impregnated into the liquid from the surface of the impregnated portion. The preservative is exuded, and a liquid preservative is applied by passing a square material or the like as an object to be applied between such a pair of application rollers.

[0004]

However, when applying a liquid preservative, if a pair of application rollers are provided vertically upright, the liquid preservative impregnated in the impregnating section will have a gravity. As a result, the liquid preservative tends to accumulate below the impregnated part because of the flow from the upper part of the impregnated part to the lower part. As a result, there is a problem that a liquid coating agent cannot be uniformly applied to the square material. 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 applying a liquid coating agent to an object to be coated.

[0006]

The present invention will be described with reference to the accompanying drawings. Referring to the drawings, a core 31 having a rotating shaft 33 and an outer peripheral surface 37 of the core 31 are overlapped along the axial direction of the core 31. A plurality of sponge-like ring members 3
8, and a coating roller 30 including a ring member 38 and a suppression member 39 interposed between the ring members 38 to suppress the drop of the liquid coating material impregnated in the ring member. Features.

By interposing a restraining member between the ring members to prevent the liquid coating material impregnated in the ring member from dropping, the liquid coating material impregnated in the ring member is prevented from flowing downward by gravity. It is suppressed by the member. As a result, the liquid coating agent is less likely to accumulate below the ring member, and the upper and lower ring members of the plurality of ring members have substantially the same amount of coating agent to be applied to the rectangular material. As a result, the liquid application agent is uniformly applied to the object.

Preferably, the restraining member 39 is formed in a ring shape. If the restraining member is formed in a ring shape, it is only necessary to insert the restraining member into the core when interposing between the ring members, and the assembling work of the application roller can be easily performed.

Further, the restraining member 39 may be formed in an arc shape. Even if the restraining member is formed in an arc shape, the liquid coating material impregnated in the ring member is less likely to flow downward due to gravity than in the related art, so that the upper ring member and the lower side The deviation in the amount of application of the coating agent applied to the square material with the ring member is reduced, and the liquid application agent is applied to the object to be applied substantially uniformly.

Further, a radial groove 39 is formed in the restraining member 39.
It is desirable to form A. If a radial groove is formed in the restraining member, when the liquid coating material travels along the restraining member and flows in the horizontal direction toward the surface of the ring member, it is actively collected in the groove and the liquid coating material is efficiently leveled. Since it can flow in the direction, the liquid coating agent does not accumulate near the inner peripheral surface of the ring member. For this reason, the liquid preservative can efficiently seep onto the surface of the ring member 38.

Further, it is preferable to provide a plurality of outlets 35A on the outer peripheral surface 37 of the core 31 at least corresponding to each ring member 38. In this manner, a plurality of outlets are provided corresponding to the ring members, and the liquid coating material impregnated in each ring member is partitioned by the restraining member, so that it is suppressed from flowing downward by gravity. Thus, each ring member is individually and uniformly impregnated with the liquid coating agent. Also from this point, the application amount of the application agent applied to the square material is almost the same between the upper ring member and the lower ring member among the plurality of ring members, and the liquid application agent is uniformly applied to the object to be applied. Become so.
