[0002]

2. Description of the Related Art Conventionally, in wooden prefabricated houses and the like, means for constructing walls, floors, roofs and the like with wooden panels has been implemented. As a wooden panel applied to the construction of such a prefabricated house, there is a wooden panel having a structure as shown in FIG. 7, for example. This wooden panel is composed of a vertical frame member 1a, 1a and a horizontal frame member 1b, 1b, and a reinforcing core member 2a extending vertically and horizontally inside a frame body 1 assembled in a square frame shape.
2b are arranged to form the frame 2, and further, these reinforcing core materials 2
In addition, a heat insulating material 3 such as glass wool is filled in the interior surrounded by a and 2b and vertical and horizontal frame members 1a and 1b, and the frame 1
The surface materials 4 and 4 made of plywood are attached to both front and back surfaces of the above.

By the way, conventionally, in order to manufacture such a wooden panel, as a pre-process, vertical and horizontal frame members 1a and 1b constituting the frame body 1 are subjected to the incision grooving, and then these frame members 1 are processed.
The frame body 1 is formed by combining the recessed grooves a and 1b, and then the reinforcing core members 2a and 2b are assembled in the frame body 1 in a cross or the like to form the frame body 2, and then on both surfaces of the frame body 2. plywood
(Face material) It is made by a method such as sticking 4, 4.
And these manufacturing processes are implemented by using the manufacturing equipment as shown in FIG. 8, for example.

Explaining this manufacturing process, first, two work crew members A and B mount the frame members 1a and 1b, which have been subjected to the recessed groove processing, on a work table 5 having a horizontal flat plate 5a. After assembling 1b in a frame shape, the frame body 1 assembled in a frame shape is transferred to the next work table 6 having a flat plate 6a which is also horizontal, and is assembled in a cross shape on the work table 6. The reinforcing core materials 2a and 2b are attached. In addition, each frame 1
It goes without saying that the a, 1b and the reinforcing core materials 2a, 2b and the like are nailed by the hands of the workers A and B by an automatic nailing machine or the like. Next, an adhesive is applied to the frame 2 in which the reinforcing cores 2a and 2b are attached to the frame 1 by the adhesive applying device 7 having the adhesive roller 7a for applying the adhesive. Then, on the flat plate 8a of the workbench 8, the face material 4 is attached to one surface of the frame 2, and the face material 4 is turned upside down and sent to the adhesive applying device 7, and the adhesive roller 7a of the adhesive applying device 7 is passed through to form the frame. Apply adhesive to the other side of 2.

Then, at the same time when the adhesive is applied, the frame 2
The inside is filled with the heat insulating material 3 cut into a predetermined size and shape, and the face material 4 is attached to the flat plate 9a of the workbench 9 from the upper surface of the framework 2. Further, the face material 4 is pressed by a press machine not shown.
The frame member 2 is clamped and then stapled or nailed to securely fix the face member 4 to the frame member 2 to obtain a wooden panel as shown in FIG. Here, the face material 4 has a large outer dimension in consideration of a finishing allowance in advance. After the manufacturing process by the manufacturing apparatus as shown in the figure, as a post-process, a normal sizer process is applied to the surface material 4, and the size of the frame is calculated. Consideration is given to a predetermined size that suits.

[0006]

However, in manufacturing such a wooden panel, various steps are improved in order to improve the productivity thereof, and particularly the step of attaching the face material to the frame is performed. The following inconveniences have occurred. In recent years, since the adhesive for adhering the face material to the frame has been remarkably improved as compared with the conventional one, the face material can be sufficiently fixed to the frame without performing a fixing operation such as stapling or nailing. Is starting to appear. However, on the other hand, since the adhesive is a so-called instant adhesive, which is a quick-hardening type, there is a problem that once the face material is placed on the frame, it cannot be replaced.

On the other hand, regarding the face material, there is a demand for minimizing the finishing allowance by the sizer in order to reduce the material cost. However, when the finishing allowance is reduced in this way, the amount of play in arranging the face material on the frame is reduced. When the play is reduced in this way, the curing of the adhesive is quick as described above and it cannot be replaced again.Therefore, the positioning of the face material in the frame requires extreme care, that is, it is a process with poor workability. It will end up. The present invention has been made in view of the above circumstances, and an object of the present invention is to enable positioning and positioning of the face material accurately and automatically when the face material is attached to the frame with a fast-curing adhesive. The purpose of the present invention is to provide a face material sticking device.
