Description: TECHNICAL FIELD The present invention relates to a manufacturing apparatus for a wooden panel frame, and in particular, a frame body is assembled into a square frame shape by a frame member, and at least the vertical and horizontal directions are provided inside the frame body. The present invention relates to a manufacturing apparatus for a wooden panel frame used when disposing a reinforcing core member assembled in a cross shape.

[Prior Art] Conventionally, in a wood-based prefabricated house, etc., a means for constructing walls, floors, roofs, etc. by so-called wooden panels made of plywood or the like has been implemented.

A wooden panel applied to the construction of such a prefabricated house has a structure as shown in FIG. 9, for example. That is, the reinforcing core members 2a and 2b extending horizontally and vertically are arranged inside the frame body 1 which is formed into a square frame shape by the frame members (core members) 1a and 1b forming the horizontal and vertical frames. To form a frame 3, the inside of which is surrounded by the reinforcing core materials 2a, 2b and the horizontal and vertical frame members 1a, 1b is filled with a heat insulating material 4 such as glass wool, and the front and back surfaces of the frame body 1 are The face materials 5 and 5 made of plywood are attached to each other.

By the way, in the conventional method for manufacturing the frame 3 for a wooden panel of this type, when the frame 3 is frame-processed, the vertical and horizontal frame members 1a and 1b and the reinforcing core member 2 which constitute the frame 3 as a pre-process.
A method is used in which a groove is machined in a and 2b, and the frame 3 is formed by combining the grooved portions of the frame members 1a and 1b and the reinforcing core materials 2a and 2b.

The wooden panel manufacturing process including the wooden panel framework 3 has been conventionally performed by using a manufacturing apparatus as shown in FIG.

That is, after mounting the frame members 1a and 1b on which the indirect groove processing has been performed on the work table 6 having the horizontal work table 6a, and by assembling these frame members 1a and 1b into a frame shape by two workers, The frame body 1 assembled in this frame shape is transferred to the next work table 7 having a similarly horizontal work table 7a, placed on this work table 7, and assembled in a cross shape to form a reinforcing core material 2a. , 2b are attached to form the wooden panel frame 3. Needless to say, each of the frame members 1a and 1b and the reinforcing core members 2a and 2b are nailed by an operator's hand by an automatic nailing machine or the like.

Next, the frame 3 having the reinforcing cores 2a and 2b attached thereto is sent to an adhesive application device 8 having an adhesive roller 8a for applying an adhesive, and the adhesive roller 8a is passed through the frame 3 to form an adhesive on one surface of the frame 3. The adhesive poured from the hopper 8b of the coating device 8 is coated. Then, on the work table 9a of the workbench 9, the face material 5 is attached to one surface of the framework 3 and the adhesive is applied to the other surface of the framework 3 by passing the adhesive roller 8a of the adhesive application device 8. To do.

Next, simultaneously with the application of this adhesive, the inside of the framework 3 is filled with the heat insulating material 4 cut into a predetermined size and shape, and the work table 10a of the workbench 10 is filled with the surface material 5 from the upper surface of the framework 3.
Then, a wooden panel as shown in FIG. 9 is manufactured.

The frame 1 and the plywoods 5 and 5 have a large outer dimension in consideration of the finishing allowance in advance, and after the manufacturing process by the manufacturing apparatus as shown in FIG. It has been processed to ensure that it has the specified dimensions.

[Problems to be Solved by the Invention] By the way, in the above-described conventional method for manufacturing a wooden panel frame 3, the work tables 6a and 7a each having a flat upper surface are provided with vertical and horizontal grooves having a recessed groove. Since the frame 3 is assembled by aligning the frame members 1a, 1b and the reinforcing core members 2a, 2b with the respective notched grooves, the conventional frame work is
There are many parts that depend on the experience and intuition of the worker, and the skill of the worker is required.

Therefore, instead of the method of performing the intermeshing groove processing as described above, a method of simply butting and combining the respective frame members 1a, 1b and the reinforcing core materials 2a, 2b, and adhering and affixing the butted portions is adopted. However, if this work is performed according to the above-described manufacturing method, the butted portions are likely to be displaced, and the frame 1
There is a problem that the workability is extremely poor, such as causing a problem such as a deviation or a distortion of the shape of the frame, or a dimensional deviation of the framework 3.

The present invention has been made in view of such circumstances, and even a skilled worker can easily manufacture a wooden panel having a shape and size that conforms to the standard, and can improve workability. It is an object of the present invention to provide a manufacturing apparatus for a wooden panel frame as described below.

[Means for Solving the Problem] The present invention is a wooden structure in which a frame body is assembled into a square frame shape by a frame material, and a reinforcing core material assembled in at least a vertical and horizontal cross shape is arranged inside the frame body. In a panel frame manufacturing apparatus, on an adjacent side portion of a work table that supports the frame,

A pin is provided so as to be retractable in correspondence with the position of the frame of the frame member and the position of the reinforcing core member, and also on the upper surface of the work table and with the first ruler, the second ruler, and Inside the framework arrangement area formed by the framework guide pins, there are provided a first frame ruler, a second ruler, and a frame framework pressing pin for fixing the frame material to the first ruler, the second ruler and the frame framework guide pin. The pin is provided with an up-and-down moving mechanism that enables the frame-shaped pressing pin to move up and down, and the up-and-down moving mechanism is rotatably attached to the lower surface of the work table, and the up-and-down moving mechanism includes the frame-based pressing pin The frame pressing pin is provided between the lower surface of the business table and a position corresponding to the first ruler, the second ruler or the frame guide pin, and the first ruler, the second ruler or the frame guide. A biasing member that biases the pin in the direction of the pin is provided, and at the upper end of this frame pressing pin, a tip end that is tapered upward is provided, and when the frame pressing pin is sunk from the work table, , By the biasing force of the biasing member,
So that the tip of this tapered portion is located inward of the frame arrangement area from the inside surface of this frame or this surface,
The arranging of the frame pressing pin was made a solution.

[Operation] When manufacturing a wooden panel using the manufacturing apparatus for a wooden panel frame of the present invention, first, a frame guide pin is projected onto the upper surface of a work table for assembling the frame,
In line with this frame guide pin and the first and second ruler,
Arrange the frame members. After that, the frame pressing pin for pressing and fixing the frame member to the first ruler, the second ruler, or the frame guide pin is made to project by operating the vertical movement mechanism.

As the framework pressing pin rises, the taper portion at the upper end of the framework pressing pin slides upward on the inner surface of the frame member. With the upward movement of the tapered portion, the biasing member is pulled and the vertical movement mechanism rotates. Along with this, the framework pressing pin horizontally moves in the direction away from the first ruler, the second ruler, or the frame guide pin against the biasing force of the biasing member. At this time, the framework pressing pin is biased by the action of the biasing member in the direction in which the frame member is pressed against the first ruler, the second ruler, or the frame guide pin.

Therefore, the frame member is strongly pressed against and fixed to the first ruler, the second ruler, or the frame guide pin, and never shifts its position or has its dimensions changed. It is possible to perform work while maintaining precision dimensions, squareness, and straightness.

After obtaining a frame body that is accurate to the standard in this way, a reinforcing core material is arranged inside the frame body at the position determined by the frame guide pin, and the butted part is fixed by adhesion and nailing. Then, a desired framework is manufactured.

In this way, the frame member and the reinforcing core member are positioned by the first ruler, the second ruler and the frame guide pin during the frame work, and the frame press pin always acts as described above. Since the first ruler, the second ruler, or the frame guide pin is strongly pressed and fixed, any worker can accurately manufacture a frame having a shape and size conforming to the standard.

Up and down, but other than this, for example, a hydraulic cylinder or the like may be used, or Of course, other than this may be used.

Further, as the urging member 38, a member other than the spring of the above-described embodiment may be used as long as it has a structure for urging the frame pressing pins 30 ... In the direction of the first ruler, the second ruler or the frame guide pin. Things may be used.

In addition, a cam attached to the upper end of the frame pressing pin 30
The shape of 40 is the tip that tapers downward.
It is not limited to the above embodiment as long as it has 40b, and other than this, for example, a shape in which only one side has an inclined surface inclined in a taper shape and the diameter is gradually reduced upward The cam 40 of can also be used. However, in this case, it is necessary to dispose the inclined surface in the direction of the frame members 1a, 1b.

Further, in the above embodiment, the concrete structure of the frame guide pin 13 is as shown in FIG. 3, but the structure is not limited to this, and the frame guide pin 13 may be pressed, for example, as shown in FIG. It may be configured to be inserted into a cylinder portion 34 of an air cylinder 33 similar to the air cylinder 33 used as a vertical movement control mechanism for the pin 30, and in this case, a mechanism similar to the vertical movement of the frame-structure pressing pin 30. Accordingly, the vertical movement is controlled.

In addition, in the above-mentioned embodiment, the manufacturing apparatus of the frame for the wooden panel is used to form the frame 3 by butt-bonding and nailing the frame members 1a and 1b and the reinforcing core members 2a and 2b without forming the notch grooves. Although the example used in the case of assembling has been described, it can also be used when assembling the frame members 1a and 1b and the reinforcing core members 2a and 2b that have been subjected to the indentation process in advance.

[Effects of the Invention] As described above, the wooden panel frame manufacturing apparatus of the present invention has the above-described configuration. Therefore, by the first ruler, the second ruler, the frame guide pin, and the frame press pin, The frame member and the reinforcing core member can be securely fixed to the correct position on the work table. Especially, the frame pressing pin is
The frame member is vertically movable, and as the pin rises, the urging force of the urging member always acts to press the frame member against the first ruler, the second ruler, or the frame guide pin. The core material for reinforcement and the reinforcing core material never cause positional deviation or dimensional deviation, and any worker can accurately assemble the target frame according to the standardized size and shape. Therefore, it is possible to standardize the frame work, improve the work efficiency, improve the size (shape) accuracy, and ensure higher quality.

Further, as described above, by securely fixing the frame material and the reinforcing core material to the correct position of the work table,
Without applying groove processing to the frame and reinforcing core,
There is the convenience that the framework can be assembled by a simple operation such as butting, adhering, and nailing. For this reason, the step of performing the recessed groove processing can be omitted, so the work can be simplified by reducing the number of processes, the cost and the construction period can be shortened, and the strength deterioration of the frame material etc. can be prevented by not providing the recessed groove. Is possible.

Further, the frame guide pin and the frame press pin can be retracted from the upper surface of the work table as described above,
Depending on the shape and dimensions of the target framework, only the necessary pins can be appropriately selected and projected, and with one manufacturing device,
Multiple types of frameworks can be manufactured. Further, if all the framework guide pins and the framework pressing pins are set in the retracted state, it is possible to smoothly transfer the framework to the next process without lifting or lifting the framework.
