2. Description of the Related Art A construction method has been widely adopted in which construction work for a house or the like is speeded up and standardized to shorten construction time on site and provide a high quality construction. As such a construction method, for example, a so-called panel construction method in which members such as walls, floors, and ceilings are made into panels, these are produced in advance in a factory, and the obtained panels are simply assembled on site to complete a house or the like. It has been known.

In such a panel construction method, wooden panels having standardized dimensions are produced in a factory to be used as wall panels and floor panels. In recent years, however, such panels have been made larger and the entire wall on one side has been enlarged. It is also said that it will be a single panel. Then, in order to manufacture such a large-sized panel, usually, a plurality of wooden panels are bonded to each other at the mouth end thereof by bonding or the like, and the desired size and shape are adjusted.

By the way, when the adhesive is applied to the wood panel surface of the wooden panel, the wood panel is set upright and the wood panel surface to be coated is made horizontal, and in that state, brush coating, roll coater, etc. are used. Adhesive is applied to the surface of the wood. However, since it is difficult to hold the large panel in an upright state, it has been demanded to apply an adhesive to the vertical wood mouth surface while lying horizontally.

FIG. 7 shows an example of an apparatus for applying the adhesive 2 to the vertical wood mouth surface 1a of the wooden panel 1 in a lying state. In this apparatus, a cylindrical coating roller 3 is arranged so that its shaft 3a is in the vertical direction, and after the adhesive 2 is supplied to the outer peripheral surface of the coating roller 3 by hand or the like, the coating roller 3 is manually rotated in the circumferential direction. Then, the adhesive 2 is applied to the vertical wood mouth surface 1a of the panel 1 by this.

However, the application of the adhesive by such an application device has the following problems. Laura 3
It takes a lot of time and labor to supply the adhesive 2 to the outer peripheral surface, and the amount of the adhesive 2 supplied varies between individuals. Also,
If the amount of the adhesive 2 supplied to the outer peripheral surface of the roller 3 is small, coating unevenness occurs. Furthermore, if the supply amount of the adhesive 2 is increased in order to avoid such coating unevenness, the adhesive drips from the excessive portion, and the surrounding work site is soiled,
The loss of the adhesive agent 2 causes the manufacturing cost to increase.

In order to solve such a problem, the present applicant previously provided a coating device. (Japanese Patent Application No. 3-93330
As shown in FIG. 6, this coating device has a cylindrical roller 15 on the upper part of a storage tank 14 for storing the coating agent 13 so as to face a vertical wood mouth surface 11a of a work (wood panel) 11 to be coated. Is arranged and is rotatable, and the roller 15

Supplying means 24 for supplying the coating agent 13 into the agent reservoir 19
Is provided.

Then, the supply agent 24 automatically supplies the coating agent 13 in the storage tank 14 to the coating agent reservoir 19, whereby the roller 15 rotating while contacting the coating agent 13 in the coating agent reservoir 19 is rotated. A certain amount of coating agent 1 on the outer peripheral surface
3 can be automatically supplied, and the grooves 17 are provided on the outer peripheral surface of the roller 15, so that the coating agent 13 is prevented from dripping by entering the grooves 17 ,. 17 ... Since the coating material 13 that has entered the inside is scraped out by the convex piece of the brush plate,
The coating agent 13 was reliably applied to the vertical wood mouth surface of the work 11 to avoid troubles such as application unevenness and dripping.

[0009]

However, in the above-mentioned coating apparatus, since the adhesive that has accumulated on the premise that the adhesive has dripped from the roller 15 is pumped up by the supply means 24 (bucket), the mechanism of the entire apparatus is obtained. Becomes complicated,
In addition, when the coating agent has a particularly high viscosity, there is a point to be improved that it is difficult to process the coating agent attached to the supply means 24 (bucket).

The present invention has been made in view of the above circumstances. An object of the present invention is to simplify the mechanism for supplying the coating agent to the coating roller, prevent uneven coating, and perform coating from the coating roller. An object of the present invention is to provide a coating device capable of preventing the dripping of the agent.
