[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and apparatus for manufacturing a panel frame for producing panels such as wall panels and floor panels.

[0002]

2. Description of the Related Art A panel in which wooden frame materials are assembled into a frame shape to form a frame and face materials such as structural plywood and particle board are attached to the frame is disclosed in, for example, Japanese Examined Patent Publication No. 61-15.
It is used as a wall panel or floor panel of a wooden building having a load bearing wall structure as described in Japanese Patent Publication No. 83.

The frame for forming the panel as described above has a plurality of wooden frame members juxtaposed on the workbench at predetermined intervals.
Place the wood-based frame material along the end surface of the juxtaposed wood-based frame material,
It is assembled by nailing both and fixing.

[0004]

In the panel frame manufacturing method and apparatus as described above, some wooden frame members have a warp, and due to this warp, a step is formed in the nailing fixing portion between the wooden frame members. Therefore, it is difficult to attach a face material such as structural plywood or particle board to the obtained frame, or if the face material is forcibly attached, the face material becomes uneven, which is not preferable in appearance, and also has sufficient strength. Sometimes I couldn't get anything.

In view of the above points, an object of the present invention is to manufacture a panel framework which does not cause a step at its connecting portion even if the wooden frame material is warped.

It is a wooden frame material (hereinafter referred to as a second frame material).

The workbench 1 is wide enough to mount a frame to be assembled, and has rails 4, 5 along one edge.
Is attached. Although not shown, pins for arranging the first frame members A at predetermined intervals are planted on the workbench, and the first frame members A are mounted on the workbench 1 by the pins. It is designed not to move left or right. The surface of the workbench 1 is smooth and serves as a reference surface.

The nailing machine 2 is for nailing and fixing the second frame member B to the end surface of the first frame member A, and is attached to the frame body 3. The frame 3 is composed of an L-shaped frame body 31 having casters 32 and 33.
2, 33 are mounted on the rails 4, 5 and can be reciprocated along the rails 4, 5. In addition, one caster 3
The legs of 3 are omitted in the drawing and only the wheels are shown.

A fluid pressure cylinder 7 is also attached to the frame body 3. The pressing tool 6 is attached to a moving rod (not shown) of the fluid pressure cylinder 7, and the pressing tool 6 can reciprocate vertically with respect to the surface of the work table 1 by the operation of the fluid pressure cylinder 7. .

The invention method according to claim 1 using the above apparatus will be described. The first frame members A are placed side by side at a predetermined interval by placing the first frame members A on the workbench 1 in the required number based on the arrangement of the pins. After that, the second frame member B is placed on the workbench 1 on the side of the rails 4 and 5, and is placed along the end surface of the first frame member A.

The frame body 2 is positioned outside the first frame member A, and the fluid pressure cylinder 7 is operated to lower the pressing tool 6. By this descent, the lower surface of the pressing tool 6 presses the end portion of the first frame member A and the portion of the second frame member that is close to the end surface of the first frame member against the surface of the work table 1 that is the reference surface. To do. By this pressing, the upper surface of the end portion of the first frame member A is flush with the upper surface of the second frame member B.

With the pressing tool 6 pressing the first frame material A and the second frame material B, the nailing machine 2 is operated to move the second frame material B to the end surface of the first frame material A on the outer side. Stick and stick. When this nailing is finished, the pressing tool 6 is raised to move the frame body 2 along the rails 4 and 5 to the position of the end surface of the first frame material A that is next arranged. At this position, the same operation as described above is performed, and nail fixing is sequentially performed. The same operation is performed sequentially, and the second
The frame material B is nailed and fixed to all the end faces of one side of the first frame material A arranged side by side.

Then, the other end face of the first frame member A is remounted on the work table so that it faces the nail driver 2, and the second frame member B is replaced with the first frame member B in the same manner as described above. Nailed and fixed to the end face of A. In FIG. 2, the second frame member B has already been replaced with the first frame member A.
3 shows a state in which the other end face of the is fixed by nailing.

Although the panel frame is assembled in this manner, a crosspiece parallel to the second frame member B may be provided between the first frame members A if necessary.

Next, the method according to the second aspect of the present invention will be described with reference to FIG. FIG. 3 is a schematic view showing an example of an apparatus used in the method according to the second aspect of the present invention. In this apparatus, two pressing tools 61 and 62 are provided, and these pressing tools 61 and 62 are separate from each other. Fluid pressure cylinders 71, 7
2 is attached to the rod body and is capable of reciprocating independently of the surface of the workbench 1 independently.
And the same device as shown in FIG. Items common to those shown in FIGS. 1 and 2 are designated by the same reference numerals as those in FIGS. 1 and 2 and their description is omitted.

In the method using this device, one pressing tool 61 presses the end portion of the first frame material A, and the other pressing tool 62 presses the second frame material B. The panel frame is assembled in the same manner.

FIG. 4 shows another example of the apparatus used in the method according to the second aspect of the present invention. In the apparatus shown in FIG. 3, the pressing tool and the reference surface are in an upside down relationship. That is, the pressing tools 61, 62 and the fluid pressure cylinders 71, 72 are provided below the surface of the workbench 1, the shape steel 8 is attached to the frame body 31 of the frame 3, and the lower surface 81 thereof serves as a reference surface. There is.

Therefore, in the method using this apparatus, one pressing tool 61 is raised against the reference surface of the lower surface 81 of the mold steel 8 to press the end portion of the first frame member A and the other pressing tool 62. The panel frame is assembled in the same manner as the above-mentioned method, except that the second frame member B is pressed by raising.

In the method of manufacturing a panel frame using the apparatus as shown in FIGS. 3 and 4, the first frame member A and the second frame member B are separately pressed against the reference surface, so that this surface is not pressed. If the face material is attached, no unevenness will occur on the face material. Thus, this method is suitable when the thickness of the frame material is different as shown in FIG.

The present invention is not limited to the above embodiment. For example, in the above-described embodiment, the pressing tool and the nail driving machine can be horizontally moved along the rail, and the first
