By tightening the screw 58, the lever member 55 can be fixed so as not to rotate.

By rotating the lever member 55 as shown in FIG. 10, the cutting blade holding block 51 can be pushed down, whereby the chamfer blade 52 is moved to the plate-like body 12 as shown in FIG. The cutting part can be moved to a position where it can be chamfered. Then, by operating the handle portion 55c in the direction of arrow R in FIG. 10, the cutting blade holding block 51 can be easily pushed up by the principle of the crank mechanism, and the chamfering blade 52 is stored in the first moving blade portion 22. be able to. As shown in FIG. 10, during the chamfering operation, the reaction force acts as shown by a white arrow, so that the lever member 55 is urged to rotate in the direction opposite to the arrow R, and the chamfering is performed. The blade 52 is prevented from being pulled into the first movable blade portion 22. That is, the distance W between the axis of the connecting pin 55b and the axis of the stopper 56 is greater than the distance of the shaft 55.
The length is set to be longer than the distance N between the axis of “a” and the axis of the stopper 56. Therefore, when the handle portion 55c is tilted as shown in FIG. 10, a reaction force (open arrow) is applied to the stopper portion 5 around the axis of the rotating shaft portion 55a.
It acts only on the connecting pin portion 55b located on the opposite side of 6. Therefore, when a reaction force is acting on the connecting pin portion 55b during the chamfering operation, the lever member 55 is urged to rotate only in the direction opposite to the arrow R (clockwise), thereby preventing loosening. The function has been activated.

Next, the board fixing bracket 80 will be described with reference to FIG.
This will be described in detail with reference to FIGS. In this embodiment, as shown in FIG. 1, board fixing brackets 80 are provided at three places on the upper main body 16. 11 is a perspective view of the board fixing bracket 80, FIG. 12 is a state in which the switching lever 82 is in the neutral position, FIG. 13 is a state where a thick gypsum board 120 which is an example of the plate-like body 12 is pressed, and FIG. The state which pressed down the thin gypsum board 121 which is another example is each shown. Reference numeral 84 denotes a push piece, which is formed in a substantially elliptical shape and is rotatably mounted on the metal fitting body 81 about an eccentric axis. As shown in FIG. 12, the distance S from the axis 84a to one end is shorter than the distance H from the other end. A switching lever 82 is fixed to the push piece 84. When the switching lever 82 is turned counterclockwise from the neutral position and tilted as shown in FIG. 13, the one end side is turned downward, so that the thick gypsum board 120 (for example, 12 mm) can be pressed. Further, if the switching lever 82 is rotated clockwise and tilted as shown in FIG. 14, the other end side is rotated downward, so that the thin gypsum board 120 (for example,
9 mm). In this way, the plate-shaped body 12 inserted and sent through the gap 14 is
8 and can be reliably fixed in a state of being suitably sandwiched between the upper surface of the base member 8. Thereby, the cutting step and the chamfering step can be accurately and reliably performed.

Reference numeral 86 denotes a wire loop tension adjusting mechanism, which is provided at one end of the upper body 16. A pulley 76 around which one end 32a of the wire loop is wound,
The position of the upper main body 16 can be adjusted in the longitudinal direction by screws 88. The wire 33 constituting the wire loop 32 (see FIG. 4) usually extends during use. On the other hand, by tightening the screw 88, the wire loop 32 can be tensioned to a suitable tension. Note that 89
Is a pulley fixing bolt. This wire loop tension adjusting mechanism 86 is also provided on one end side of the lower main body 18. By the tension adjustment mechanism 86 of the upper and lower wire loops,
When the pulley 76 of the upper main body 16 is pulled, the first movable blade portion 22 is pulled, and when the pulley 77 of the lower main body 18 is pulled, the second movable blade portion 28 is pulled. Thereby, the upper and lower cutting blades 24a,
The displacement can be adjusted before and after 24b.

Next, a method of cutting a gypsum board (plate-like body 12) using the plate-like body cutting machine having the above-described configuration will be described. First, the plate-like body 12 to be cut is placed in the gap 1
4 and is placed at a predetermined position using a scale 40a. Next, the plate-like body 12 is
Is fixed. However, in order to perform the work efficiently, the worker may hold the plate-shaped body 12 by hand. Then, the handle 19 is gripped and pulled toward the near side where the feed guide section 40 including the scale 40a and the step section 40b for preventing displacement is provided. Thereby, as shown in FIG. 2 and FIG. 3, the paper 12x and 12y on the front and back of the plate-shaped body 12 are cut by the pair of rotary blades (cutting blades 24a and 24b). At this time, by pulling on the handle 19, the first movable blade portion 22 to which the handle 19 is fixed is directly moved, and the second movable blade portion 28 is synchronized with the first movable blade portion 22 by the synchronous moving means 30. Moving. At this time, the plate-like body 12
Since the cut is made from the front and back at the same position, the pressing force from both sides is cancelled, and it is prevented from floating or being bent. Further, since the cutting blades 24a and 24b can rotate, the resistance at the time of cutting can be reduced, and the paper on the front and back of the plate-shaped body 12 can be cut smoothly and easily. After this cutting step,
The handle 19 is pushed back to the original position.

Next, as shown in FIG.
By breaking the gypsum core material 12c, the plate-like body 12 is cut into a predetermined size. The cut plate-like body 12 is held as it is in a plate-like body cutting machine. The lever member 5 provided on the first movable blade portion 22
5 is rotated to make the chamfer blade 52 protrude. In this state,
The chamfer is performed by pulling the handle 19 again toward the user. After this chamfering step, the handle 19 is pushed back to the original position. Next, the fixing of the plate-shaped body 12 by the board fixing bracket 80 is released, and the work of one cycle of cutting and chamfering the plate-shaped body 12 is completed.

According to the above steps, the front and back surfaces 1
The papers 2a and 12b can be cut at the same time. That is, since the steps that have been conventionally performed separately can be reduced to one step, the working efficiency can be improved.
Further, since the cutting blades 24a and 24b can be moved straight since they are suitably guided by the first guide 20 and the second guide 26, the cutting trace becomes a clean straight line. Also, the cutting blades 24a, 24
b can be suitably adjusted in position and attached, and can be moved (run) with high accuracy along the first guide 20 and the second guide 26. Therefore, the depth of cut can be made uniform with high accuracy. Therefore, the plate-shaped body 12 can be neatly cut into a desired size. In addition, the state held for cutting the plate-like body 12 can be maintained, and chamfering can be performed in the next step. In other words, the handle 19 does not need to be positioned and held again, and
With only the above operation, chamfering can be performed efficiently and easily.

Further, according to the present invention, since power such as an electric motor is not required, it can be provided at low cost. In addition, the plate-like body 12 having various thicknesses (for example, 9 mm or 12 mm).
Can respond to. It is a field-assembled type, has a structure that can be reduced in weight by using aluminum material, and is easy to use. And because it can be easily stored in a box etc. by being assembled,
The accuracy of the equipment is maintained. Further, since commercially available round blades can be used as the cutting blades 24a and 24b, maintenance management is easy. Furthermore, by giving the feed guide section 40 a function of finely adjusting the angle, the plate-shaped body 12 can be cut with high precision (such as right-angle precision).

In the above embodiment, the case where a gypsum boat as an example of the plate-like body 12 is cut has been described. However, the present invention is not limited to this, and other applications include corrugated cardboard, paper, nylon, and vinyl chloride. Suitable for sheets, rubber sheets and thin metal plates. However, when cutting a thin plate, as shown in FIG. 17, the upper and lower cutting blades may be shaped so as to rub each other.
What is necessary is just to cut | disconnect an object to be cut by pulling 9 once.

In the above embodiment, a case where a rotary blade (round blade) is used as the cutting blades 24a and 24b has been described. However, the present invention is not limited to this, and a triangular or elliptical cutting blade which does not rotate is used. You may. As described above, the present invention has been described variously with reference to preferred embodiments. However, the present invention is not limited to the embodiments, and it is needless to say that many modifications can be made without departing from the spirit of the invention. That is.

[0032]

According to the present invention, it is possible to simultaneously and suitably cut both sides of the plate. In other words, the steps that have been conventionally performed separately can be reduced to one step, so that the working efficiency can be significantly improved.
Further, since the guide is suitably guided by the first guide and the second guide, the pair of cutting blades corresponding to the front and back of the plate can be moved straight, and the plate 12 can be cut cleanly into a desired size. It has a remarkable effect.
