DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sizer device for producing wood panels used as building materials for prefabricated houses and the like, and finally finishing the shape of the wood panels to be manufactured by cutting.

[0002]

2. Description of the Related Art Generally, in a wooden prefabricated house or the like, means for constructing a wall, a floor, a roof, or the like with a wooden panel is used. As a wood panel applied to the construction of such a prefab house, for example, FIG.
There is a structure as shown in FIG. This wood panel P
Are frame materials (core materials) 1a, 1b constituting vertical and horizontal frames
A reinforcing core material 2a, 2b extending vertically and horizontally is arranged inside a frame body 1 assembled in a rectangular frame shape to form a framework 2. Further, these reinforcing core materials 2a, 2b and a vertical and horizontal frame material 1a are provided. 1b is filled with a heat insulating material 3 such as glass wool, and face materials 4 and 4 made of plywood are stuck on both front and back surfaces of the frame 1, respectively.

[0003] The manufacturing process of the wood panel P will be briefly described. First, after the frame members 1a and 1b are assembled in a frame shape,
The reinforcing core members 2a and 2b assembled in a cross or the like are attached. Next, an adhesive is applied to the frame 2 in which the reinforcing cores 2a, 2a are attached to the frame 1. Then, the face material 4 is stuck on one surface of the framework 2 and further turned over, and an adhesive is applied to the other surface. Next, simultaneously with the application of the adhesive, the inside of the framework 2 is filled with the heat insulating material 3 cut into a predetermined size and shape, and the face material 4 is attached from the upper surface of the framework 2. Here, the face material 4 is set to have a large outer dimension in consideration of a finishing allowance in advance.

[0004] As a finishing process for the manufacture of the wood panel P, a sizer finish for cutting the finishing margins of the four side edges of the wood panel P is performed. By the way, a conventional sizer device for performing such sizer finishing has a pair of disk-shaped rotary blades arranged in parallel, and the interval between these rotary blades is set to the standardized width or length of the wooden panel. It is made to correspond. Then, by passing the wooden panel between these rotary blades, two opposite side edges of the wooden panel are cut and finished.

[0005]

However, in the sizer, the wood panel is passed between the rotary blades to cut and finish one of the opposing side edges, and thereafter, the other side edge is made the same. However, in such a cutting method, if the surface of the wood panel is distorted in an arc shape, the wood panel may be shifted in the horizontal direction with respect to the traveling direction, and it is somewhat difficult to finish the wood with sufficient accuracy. There was difficulty.

[0006] Further, in the sizer finishing by such an apparatus, although the opposing side edges are shaped in parallel with high accuracy, it is difficult to accurately make the corners of the wooden panel into a right angle. That is, in the sizer device, a mechanism is not provided such that an angle between adjacent side edges of the wood panel becomes a right angle, and thus, after cutting one opposing side edge, the other When cutting the side edge of the wood panel, the worker will determine the running direction of the wood panel, so that a squareness with sufficient accuracy cannot be obtained,
On the other hand, if this is done carefully, it takes time and results in a loss of productivity.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a sizer device capable of cutting and finishing a wood panel so that the size and shape of the wood panel are higher than the standard. It is in.

Are fitted with the positioning pins 37, and the third
Then, the fourth positioning members 41 and 42 are rotated to position the fixing pins (not shown) on the side edges of the table surface 35a.

Then, these fixing pins come into contact with and press against the frame members 1a and 1b of the wooden panel P, and the wooden panel P
The two cut sides are brought into contact with the positioning pieces 39 of the positioning pins 37, respectively. By such an operation, the wood panel P is set in advance by the positioning holes 36 and the positioning pins 37 on the basis of the two sides cut and finished at high accuracy by the first sizer device 10 at a right angle. They are placed in the proper position.

Subsequently, in the same manner as in the operation of the first sizer device 10, the third and fourth fixing members 43 and 44 are moved down as shown in FIGS. , And the third sizer device 45 and the fourth sizer device 46 are sequentially driven as shown in FIG. 10D to remove the finishing allowance of the face material 4 and finish the sizer finishing. Then, the positioning pins 37 are removed from the positioning holes 36, the third and fourth fixing members 43 and 44 are further raised, and the wooden panel P is moved to the next step.

In such a sizer device, the first
And by driving and driving the second sizer machines 13 and 14, the finishing allowance of two adjacent sides of the wooden panel P can be cut at a high-precision right angle, and further, based on these two sides. By cutting and finishing the other two sides with high-precision squareness by the third and fourth sizers 45 and 46, the entire squareness can be sizer-finished with extremely high accuracy. In addition, since the sizers 13 and 14 (45 and 46) are run and cut in a state in which the wood panel P is fixed, even when the face material is distorted in an arc shape, the finishing allowance is accurately corrected in order to correct the distortion. Can be cut. Further, the first sizer device 10
After the two sides are cut and finished, the other two sides are cut and finished with reference to the two sides cut and finished by the second sizer device 11, so that the sizer finishing is quickly performed by making these operations continuous. It is possible,
Thereby, productivity can be improved.

The second sizer 11 in the above embodiment is also an embodiment of the sizer according to claim 1 of the present invention. P sizer finish is possible. That is, in a state where the positioning pins 37 are not fitted in the positioning holes 36, cutting is performed in the same manner as in the cutting in the first sizer device 10 described above.
Next, by turning the wood panel P half a turn, and performing cutting in the same manner as cutting with the sizer device 11,
The sizer finish can be completed.

[0030]

As described above, in the present invention, the sizer according to the first aspect of the present invention drives the first and second sizers so that the two sides of the wooden panel have a finishing margin. Can be cut at a high-precision squareness, and furthermore, by turning the wood panel a half turn, the cut and finished two sides are brought into contact with a positioning pin fitted in a positioning hole at a predetermined position, and these are cut. Based on
