Abstract

PROBLEM TO BE SOLVED: To prevent counter-facing piercing bodies from colliding with each other during dividing between the piercing bodies and being broken by forming the counter-facing piercing bodies in such a manner that their tips are located at positions deviated in the axial center line of a rotary shaft. SOLUTION: Each of piercing bodies 21 formed around a piercing roll 23 is constituted of a face 21a extending in the radial direction of a drive shaft and a face 21b which crosses over the face 21a at 20 deg.. A piercing body 22 which is likewise formed around a piercing roll 24 is constituted of a face 22a extending in the radial direction of the drive shaft and a face 22b which is in parallel with the face 21b and crosses over the face 22a at 20 deg.. In addition, the counter-facing piercing bodies 21, 22 are of such a construction that the tips 21c, 22c of the counter-facing piercing bodies 21, 22 are deviated from each other in the axial center line of the drive shaft, i.e., to the right and the left. On the other hand, the tips of the piercing bodies 21, 22 are overlapped over each other by 0.7 mm in the vertical direction.

接着した時の商品価値が低下してしまうのである。In the conventional apparatus, as shown in FIG. 10, the piercing rolls 5, 6 are arranged to face each other, and the tips of the piercing bodies 3, 4 are cut parallel to the horizontal line. Blade 3a,
4a, the piercing bodies 3, 4 are piercing rolls 5,
6 are disposed at relatively small intervals in the rotation direction on the outer periphery of the piercing member 6, and the driving shafts 1 and 2 are bent by the force received when the wood fiber board P is divided.
If the distance between the tip ends of the piercing members is not at least about 1 mm, the piercing members 3, 4 are opposed to each other during rotation and the piercing members 3, 4 are damaged, and the force from the drive shafts 1, 2 is reduced.
For example, there is a problem that the splitting cannot be performed without being transmitted to the wood fiber board P. However, if the distance between the tips of the opposed piercing bodies 3 and 4 is set to about 1 mm as described above, the piercing body can be pierced at a sufficient depth from the surface in the case of a relatively thin plate-like body having a thickness of, for example, 1.5 mm. In the case of a plate-like body made of a hard material as well, a sufficient depth cannot be pierced, and the division becomes difficult. Of course, if the piercing rolls 5 and 6 are arranged not in the positions facing each other but in the direction of the center line of the drive shafts 1 and 2, the above problem will be eliminated. However, in order to improve the surface divided as described above, the regulating members 7 and 8 provided at opposing positions on the front and back sides of the wood fiber board P at a position immediately before the division by the dividing blade 9. It is necessary to press the wood fiber board P in the thickness direction from the front and back surfaces by the front end surfaces 7a and 8a. If the wood fiber board P is displaced in the axial center line direction, this pressurization cannot be performed sufficiently. In addition, the unevenness of the divided surface is large, and the commercial value when bonded to another plate material is reduced.

脂のシートを接着し、建物の床材や内装材に使用する。In this division, the piercing bodies 21 and 22 are pierced deeper than the center in the thickness direction of the wood fiber board S as shown in FIG. 3, but as clearly shown in FIGS. The tips 21c and 22c of the piercing bodies 21 and 22 are
At a position shifted in the axial center line direction of the drive shaft 1 or 2,
Since the rotating trajectories are different from each other, the trajectories are not damaged by hitting. During the division, an abnormal force acts on the piercing body 2
The tip of 1 or 22 is bent in the left-right direction in FIG.
Even when the two piercing bodies 21 and 22 receive a force to approach each other, the front end 21c of the piercing body 21 and the front end 22c of the piercing body 22 which are opposed to each other hardly hit. On the other hand, the regulating members 7 and 8 press the wood fiber board S at positions opposing each other with the wood fiber board S interposed therebetween.
Can be effectively pressed as compared with the case where the pressing is performed in a state of being displaced with respect to the wooden fiberboard S divided by the dividing blade 9.
The divided surfaces of a and Sb are good surfaces with little unevenness. These divided wood fiber boards Sa and Sb are sequentially peeled off from the piercing bodies 21 and 22 by the surfaces 10a and 11a of the peeling members 10 and 11 and transferred to the unloading conveyors 13 and 14 as in the conventional apparatus. It is transported to the process. With the wood fiber boards Sa and Sb thus obtained,
For example, a product obtained by dividing MDF is adhered to the surface of a plywood, and a veneer or a sheet of vinyl chloride resin is adhered onto the adhered MDF to be used for flooring and interior materials of a building.

る回転体を用いても良い。Although the embodiment of the present invention has been described above, the present invention may be modified as follows. 1. In FIG. 3, the angle at which the surface 21a and the surface 21b of the piercing body 21 intersect may be about 10 degrees to 30 degrees. The same applies to the piercing body 22. 2. The angle Z of the tip of the piercing body 21 shown in FIG. 5 may be about 20 to 50 degrees. 3. The shape of the opposing piercing body in the cross section shown in FIG.
It is not always necessary that they be the same, but the point is that the tips of the opposing piercing bodies may be located at positions shifted in the axial center line direction of the drive shaft, and as shown in FIG.
The angle formed by a and 25b is larger than the angle formed by the surface 22a and the surface 22b of the piercing body 22, so that the tip 25c and the tip 22c are shifted from each other in the axial center line direction. Is also good. 4. The shape of the piercing body in the cross section shown in FIG. 3 may be a piercing body 26 in which the surface 26b is formed as a curved line instead of a straight line as shown in FIG. The piercing body 27 having the two surfaces 27a and 27b described above may be used. Also in this case, the distal end 26c and the distal end 27c are configured to be shifted from each other in the axial center line direction. 5, the tips of the piercing bodies 21 and 22 shown in FIG. 4 are sharp, but as shown in FIG. 8, which corresponds to an enlarged explanatory view of a circle D in FIG. It may be formed so that the width in the left-right direction is, for example, about 0.5 mm. 6. In the present invention, the position of the tip of the opposing piercing body in the facing direction, that is, the position in the vertical direction of FIG. 3, may be such that both ends are spaced apart. Even in this state, the piercing bodies do not come into contact with each other even if both ends approach due to the drive shaft being bent by an abnormal force. 7. When dividing the plate-shaped body, the position of the cutting edge of the divided blade is fixed to a state shifted to one side from the center in the thickness direction of the plate-shaped body, instead of being bisected in the thickness direction, and the thickness is different. Two plate-like bodies may be obtained. 8. As the pressing member, in addition to the bar-type regulating members 7 and 8 in the above-described embodiment, in order to reduce the frictional force, the rotation is rotatably supported by a bearing at a position where the plate-like body is pressed. A body may be used.
