Description

  The present invention relates to a board cutting machine, and more particularly, to a board cutting machine capable of cutting a gypsum board in a horizontal direction or a vertical direction and chamfering a cutting portion, thereby greatly improving workability.

  Gypsum board is widely used as a base material for walls and ceilings for building interiors. Generally, a gypsum board has a structure in which gypsum powder is hardened in a flat plate shape and paper is pasted on both sides thereof.

As described above, the gypsum board is sold on a regular scale, so it is necessary to cut it according to the building. As a general cutting method in a construction site, a method is used in which cuts are made on both sides of a gypsum board with a cutter knife and folded along the cuts. In this cutting method, since the cut surface after cutting is uneven, it is necessary to finish the cut surface with a special planer or the like, and it is necessary to improve workability. In addition, there is a method of cutting with a circular saw or the like so that the cut surface is not uneven, but in this case, there is a disadvantage that a large amount of cutting powder is generated and the working environment is deteriorated.
For this reason, various techniques for cutting a gypsum board have been proposed and disclosed.

For example, a pair of upper and lower supports that can be guided and moved on both front and back surfaces of a building board such as a gypsum board, an interval holding member that holds an interval between the two supports, and a structure interposed between the two supports. A construction board comprising a position regulating member for regulating the end face of the construction board and a pair of upper and lower blade bodies attached to both supports via a holder and forming cuts on both front and back surfaces of the construction board The technique of a cutting tool is disclosed (for example, patent document 1).
According to this technology, the building board can be cut quickly and safely.

Also, chamfer the corners of the chamfered material in the corners of the horizontal and vertical parts on the L-shaped base material that contacts the surface and side surfaces of the chamfered material such as gypsum board at the horizontal and vertical parts. A technique of a chamfering tool such as a gypsum board is disclosed in which a disk cutter having an inclined blade surface is rotatably mounted on a mounting shaft provided at the front and rear center positions of the base material (for example, Patent Document 2).
According to this technique, it is possible to efficiently and labor-saving chamfering such as a plaster board.

Furthermore, it is a device that performs cutting processing of gypsum board and chamfering on one side of the ridge part of the cutting part almost simultaneously with a circular saw, and has a circular saw for chamfering with a smaller diameter on one or both sides of the cutting circular saw. A technique of a cutting device configured by detachably stacking is disclosed (for example, Patent Document 3).
According to this technique, the cutting process and the chamfering process on one side of the ridge part of the cutting part can be performed almost simultaneously in one step.

  However, although the building board cutting tool described in Patent Document 1 can quickly and safely cut the building board, it is necessary to perform the chamfering work after cutting as a separate work. There was a problem that the nature was bad. In addition, it is necessary to work by placing the building board on a table laid on the work floor, and there are many cases where the work is carried out with a middle waist posture, and there is a problem that physical fatigue is large. Furthermore, there is a problem that the work space cannot be saved because a large work space is required to lay the building board.

Further, the chamfering tool such as gypsum board described in Patent Document 2 can perform chamfering such as gypsum board efficiently and labor-saving, but it is necessary to perform the cutting work as a separate work, and the workability is improved. There was a problem of being bad.
Furthermore, although the technique of the cutting device described in Patent Document 3 described above can perform cutting and chamfering on one side of the edge of the cutting portion almost simultaneously in one step, a large amount of cutting powder is generated and the working environment is poor. There was a problem of becoming.

  In order to solve the above-mentioned problems, the present invention efficiently cuts and chamfers a standing posture in an easy working posture by cutting the gypsum board in a standing state and chamfering the cutting portion.

(Cutting means)
The cutting means 2 is provided on the back surface 12 side of the gypsum board 10, and the cutting means 2a for cutting to which the cutting blade 21 is attached, and the chamfering that is provided on the surface 11 side of the gypsum board 10 and to which the chamfering blade 25 is attached. Cutting means 2b. That is, two chamfers for chamfering both corners of the cutting portion 21 cut by the cutting blade 21 from the surface 11 of the gypsum board 10 and the cutting blade 21 for cutting the gypsum board 10 from the back surface 12 of the gypsum board 10. A configuration having a blade 25 is provided. In this way, when the gypsum board 10 passes between the chamfering blade 25 and the cutting blade 21, the gypsum board 10 can be cut and the cut portion can be chamfered, so that the cutting operation and the chamfering operation on the surface 11 side are performed. Can be performed collectively, and work efficiency can be improved.

Moreover, the combination of the cutter with respect to the gypsum board 10 of this invention is not limited to the said combination. For example, as a combination of the blade on the front surface 11 side / the blade on the back surface 12 side of the gypsum board 10, in addition to the chamfering blade 25 / cutting blade 21 of this embodiment, the cutting blade 21 / chamfering blade 25, for cutting. Combinations of the blade 21 + the chamfering blade 25 / the chamfering blade 25, the chamfering blade 25 / the cutting blade 21 + the chamfering blade 25, and the like can be given. In this way, by providing the chamfering blade 25 on both sides of the gypsum board 10, the front surface 11 side and the back surface 12 side can be chamfered.
Furthermore, it is also possible to provide the cutting blade 21 on both sides of the gypsum board 10, and the combination of the cutting tool on the front surface 11 side / the cutting tool on the back surface 12 side may be the cutting blade 21 / cutting blade 21. If it does in this way, cutting ability can be improved and thick gypsum board 10 can be cut easily.

  As shown in FIGS. 3 and 5, the cutting blade 21 and the chamfering blade 25 are disk-shaped round blades with blades around the entire circumference. By using a round blade, when a predetermined blade portion is worn by cutting, the round blade is rotated and can be fixed again so as to cut the gypsum board 10 with an unused blade portion. In addition, the replacement life of the chamfering blade 25 can be extended.

FIG. 3: has shown the general | schematic enlarged exploded view of the principal part for demonstrating the cutting means and moving means by the side of the cutting tool of the board cutting machine concerning one Embodiment of this invention.
In the drawing, the cutting means 2a on the cutting blade 21 side includes a cutting blade 21, a fixing plate 211 in which the center of the cutting blade 21 is screwed by a bolt (not shown), and the fixing plate 211. It has a configuration including a blade receiver 22 attached almost at the center.

  The blade receiver 22 includes an annular flat plate and a cylindrical shaft portion 22a projecting from the back surface side of the center hole of the flat plate. The shaft portion 22a is a circular hole 451 of the vertical moving plate 45. And is attached to the vertical movement plate 45 in a rotatable manner. In this way, the blade receiver 22 is rotated to adjust the direction of the cutting blade 21 in the horizontal direction or the vertical direction. For example, the blade receiver 22 is moved vertically by using a bolt or the like (not shown). By fixing to 45, the cutting direction of the cutting blade 21 can be freely set. Therefore, for example, even when the gypsum board 10 is cut in the horizontal direction and the vertical direction, the cutting direction can be easily changed by rotating the blade receiver 22.

  The cutting means 2a includes two link mechanisms including a blade receiver 22 as a follower, a center plate 222 as a fixed link, two connecting rods 223, and a cutting direction switching lever 224 as an original clause. ing. Both ends of the connecting rod 223 are rotatably connected to the cutting direction switching lever 224 and the blade receiver 22 via pins 221. The center plate 222 has an upper end rotatably connected to the cutting direction switching lever 224 via a pin 221, and a lower end fixed to the vertical movement plate 45. In this way, when the upper cutting direction switching lever 224 is rotated in the counterclockwise direction when viewed from the front direction around the pin 221 at the upper end of the center plate 222, as shown in FIG. Since the cutting blade 21 rotates in the counterclockwise direction and faces the horizontal direction, the gypsum board 10 can be cut in the horizontal direction. Further, as shown in FIG. 4, when the cutting direction switching lever 224 is rotated in the clockwise direction when viewed from the front, the blade receiver 22 rotates in the clockwise direction, and the cutting blade 21 is directed in the vertical direction. The gypsum board 10 can be cut in the vertical direction.

FIG. 5: has shown the general | schematic enlarged exploded view of the principal part for demonstrating the cutting means by the side of the cutter for chamfering of the board cutting machine concerning one Embodiment of this invention.
In the figure, the cutting means 2b on the chamfering blade 25 side is different from the cutting means 2a in that it has two chamfering blades 25 instead of the cutting blade 21. The other components are almost the same as the cutting means 2a. Moreover, the cutting means 2b provided with the chamfering blades 25, 25 is provided opposite to the cutting means 2a provided with the cutting blade 21 (see FIG. 2).
Therefore, in FIG. 5, the same components as those in FIG. 3 are denoted by the same reference numerals, and detailed description thereof is omitted.

The cutting means 2b has a pair of fixed plates 251 mounted opposite to each other at substantially the center of the annular blade receiver 22, and the chamfering blade 25 is disposed on the tapered surface 252 of the fixed plate 251. It is attached so that the tip approaches.
Further, as shown in FIG. 6, the chamfering blade 25 (which will be described separately as appropriate, 25 a and 25 b) and the cutting blade 21, the cutting edge tips C ₁ and C ₃ of the blades 25 a and 25 b, and the cutting tool 21. When the cutting edge tip C ₂ is in the order of C ₁ , C ₂ , C ₃ , for example, with respect to the cutting direction and when viewed from the side, each cutting edge tip C ₁ , C ₂ , C ₃ is at one point C _0. Are arranged side by side so as to converge. In this way, it is possible to avoid interference between the blade tips C ₁ , C ₂ , C ₃ , and to cleanly finish the cut surface 13 and the chamfered surface 14 as shown in FIG.

In addition, the cutting means 2b is connected to the cutting direction switching lever 224 of the cutting means 2a via the pin 221 so that the upper end of the connecting rod 223 is rotatable, and the upper end of the center plate 222 is connected via the pin 221. The cutting direction switching lever 224 of the cutting means 2a is rotatably connected. That is, the cutting means 2b shares the cutting direction switching lever 224 (see FIG. 2) of the cutting means 2a. If it does in this way, the cutting direction of the cutting blade 21 and the chamfering blade 25 can be changed synchronously by rotating one cutting direction switching lever 224. Further, by moving up and down one cutting direction switching lever 224, the cutting blade 21 and the chamfering blade 25 can be moved in the vertical direction in synchronism, so that workability can be improved. Further, the cutting direction and the vertical position of the cutting tool 21 and the chamfering tool 25 can always be made to coincide with each other with high accuracy, and the cutting direction and the vertical position of the cutting tool 21 and the chamfering tool 25 are shifted. It can be avoided.
In this embodiment, the chamfering angle is about 45 °, but the angle is not limited to this. Moreover, although the both sides (the upper side and the lower side in FIG. 7) are chamfered, it is good also as a structure which chamfers any one.

  Although not shown, the cutting means 2b is connected to a rotation restricting means for restricting the rotation of the blade receiver 22 (for example, a knock pin fitted into the vertical movement plate 45 and the blade receiver 22 or a center plate 222). And a fixing plate and a pin for fixing the position of the rod 223. In this way, the cutting direction switching lever 224 is operated, and the orientation of the cutting blade 21 and the chamfering blade 25 can be easily and accurately adjusted to the horizontal direction, the vertical direction, etc., and the state is maintained. Can be fixed.

(transportation)
The moving means 4 includes a main moving means 4a for moving the cutting means 2a, and a slave moving means 4b that is provided opposite to the main moving means 4a and moves the cutting means 2b.
As shown in FIG. 3, the main moving means 4a includes a vertical moving plate 45, a horizontal moving member 41a, and a rail 411 for moving in the horizontal direction.
The vertical moving plate 45 is a square flat plate with a circular hole 451 formed in the center, and rollers 452 with grooves for sandwiching a pair of rails 453 for moving in the vertical direction are rotatably provided at the four corners. In this way, the vertical moving plate 45 has a grooved roller 452 sandwiching the rail 453 so that the position in the front / rear direction is defined, and the pair of rails 453 are opposed to each other in the water direction. Since two sets of rollers 452 are inserted, the position in the horizontal direction is defined. That is, since the vertical movement plate 45 moves only in the vertical direction along the rail 453, the gypsum board 10 can be cut in a stable state when the gypsum board 10 is cut in the vertical direction.

  The horizontal moving member 41a includes a vertically long plate material that forms a groove shape including the substrate 412 and the side plate 413, rails 453 provided at the front end of the side plate 413, and rollers 414 provided at the four corners on the back side of the substrate 412. It is made up of. The horizontal direction moving member 41a is placed on the two rails 411 provided on the placing table 3 such that the grooved roller 414 sandwiches the rail 411. In this way, the horizontal direction moving member 41 a is regulated in the front / back direction and vertical position, and can move in the horizontal direction along the rail 411. The main moving means 4a can be an assembly type that can be easily disassembled and assembled by placing the rollers 414 on the rails 411. When the board cutting machine 1 is transported, the main moving means 4a can be moved between the moving means 4 and the mounting table 3. Can be divided and transported easily.

  Further, although not shown, the main moving means 4a is attached in the vicinity of a horizontal position measuring means (for example, in the vicinity of the upper rail 411) for measuring the horizontal position of the cutting blade 21 oriented in the vertical direction. In addition, it may be configured to include a horizontal position measuring means or the like that includes a rail attached with a scale and a pointer that moves on the scale and is connected to the horizontal movement member 41a. In this way, when cutting the gypsum board 10 in the vertical direction, the cutting tool 21 can be efficiently and accurately aligned with the cutting position.

  Further, as shown in FIG. 8, the main moving means 4a is arranged so that the main moving means 4a moves in a state where the main moving means 4a is maintained at a right angle with respect to the rail 411 (for example, along the upper and lower rails 411). A pair of upper and lower racks 461 fixed to the mounting table 3, one rotating shaft 463 rotatably provided on the horizontal movement member 41 a, and fixed to both ends of the rotating shaft 463 that meshes with the pair of racks 461. It is preferable to have a configuration including a horizontal direction synchronous moving means or the like including a pair of pinions 462. In this way, for example, when the upper part of the main moving means 4a is pushed in the horizontal direction, this force is transmitted to the lower rack 461 via the rotating shaft 463 and the pinion 462, and the upper and lower parts of the main moving means 4a are synchronized. Move in the horizontal direction. Therefore, when the lower part of the gypsum board 10 is cut in the horizontal direction, even if the upper part of the main moving means 4a is pushed in the horizontal direction, the main moving means 4a is inclined in the pushing direction due to the resistance of the cutters 21 and 25. It is possible to avoid problems such as end. As a result, the gypsum board 10 can be stably cut.

The horizontal synchronous movement means functions as a fixing means when a rotation preventing member (not shown) for preventing the rotation of the pinion 462 is provided, and is aligned when the gypsum board 10 is cut in the vertical direction. The main moving means 4a can be fixed to the mounting table 3 so as not to move in the horizontal direction.
In addition, the main moving unit 4a of the present embodiment is configured to be manually moved in the horizontal direction, but is not limited to this configuration. For example, the pinion 462 may be driven by a stepping motor or the like. . In this way, the main moving means 4a can be automatically moved, aligned and fixed.
Further, since the cutting blade 21 receives a large force in the back surface direction when cutting, as shown in FIG. 9, the vertical moving plate 45 is provided with a roller 471 that travels in the vertical direction, and the horizontal moving member 41a. A rail 472 on which the roller 471 travels may be provided on the front side of the substrate 412. In this way, the cutting blade 21 can be stably moved in the vertical direction.

The follower moving means 4b for moving the cutting means 2b is connected to the main moving means 4a by the connecting plate 46 so that the cutting means 2a and the cutting means 2b face each other (see FIG. 2). As shown in FIG. 5, the slave moving means 4b includes a vertical moving plate 45 and a horizontal moving member 41b.
Compared with the main moving means 4a, the slave moving means 4b is provided with a connecting plate 46 instead of the roller 414, and the connecting plate 46 connects the horizontal moving member 41b to the horizontal moving member 41a. . Other components are substantially the same as those of the main moving means 4a.
Therefore, in FIG. 5, the same components as those in FIG. 3 are denoted by the same reference numerals, and detailed description thereof is omitted.

The horizontal direction moving member 41b is connected to the horizontal direction moving member 41a via the connecting plate 46. When the horizontal direction moving member 41a moves in the horizontal direction, the horizontal direction moving member 41b moves in the horizontal direction in synchronization with the horizontal direction moving member. When 41a is positioned, it is positioned together. Further, since the cutting means 2b is attached to the vertical movement plate 45, it can move freely in the vertical direction.
The connecting plate 46 is provided at the upper end and the lower end of the horizontal movement member 41b, and moves above and below the plaster board 10 that is laid sideways, so that it does not interfere with the plaster board 10. Absent.

  Although not shown, the secondary moving means 4b is affixed to the vertical position measuring means (for example, the front face of the center plate 222) for measuring the vertical position of the cutting blade 21 in the horizontal direction. And a vertical position measuring means that is connected to the upper portion of the horizontal direction moving member 41b and includes a pointer that moves on the scale. In this way, when cutting the gypsum board 10 in the horizontal direction, the cutting blade 21 can be efficiently and accurately aligned with the cutting position.

Further, as shown in FIG. 10, the secondary movement means 4b includes a fixing means (for example, a rack 481 provided on the horizontal movement member 41b, a rack 481 provided on the horizontal movement member 41b, and the rack 481). It is preferable to have a configuration including a pinion 482 that is engaged with the vertical movement plate 45 so as to be rotatable and a rotation preventing member (not shown) that prevents the pinion 482 from rotating. In this way, when the gypsum board 10 is cut in the horizontal direction, the aligned vertical movement plate 45 can be fixed to the horizontal movement member 41b so as not to move in the vertical direction.
Although the slave moving unit 4b of the present embodiment is configured to manually move in the vertical direction, the configuration is not limited to this configuration, and for example, the pinion 482 may be driven by a stepping motor. In this way, the vertical movement plate 45 can be automatically moved, aligned and fixed.

  The support member 321 has a boomerang shape in plan view, and a central portion thereof is rotatably supported by a rotation shaft 323. Further, the arms 3211 and 3212 on both sides of the support member 321 have a stepped portion (board support portion) 3213 on which the gypsum board 10 is placed at the tip, and a curved surface 3214 on the front side. Further, a triangular locking groove 3215 is formed in the center of the back surface side of the arms 3211 and 3212.

  The locking member 322 has a structure including a wedge 3221 engaged with the locking groove 3215 and a contact portion 3222 that contacts the horizontal movement member 41a that moves in the horizontal direction. The abutting portion 3222 has a central portion protruding to the front side and tapered surfaces on both the left and right sides. When the abutting portion 3222 abuts against the horizontal moving member 41a that moves in the horizontal direction, the front side is pressed by a compression spring (not shown) or the like. The locking member 322 biased in the side direction functions as a driven portion of the cam mechanism and moves in the back side direction. In the cam mechanism, the horizontal movement member 41a functions as a driving part.

On both sides of the horizontal movement member 41a, mounting rollers 454 for supporting the gypsum board 10 mounted on the stepped portion 3213 from below are provided.
Further, it is preferable to provide contact rollers 455 that contact the contact portion 3222 and the curved surface 3214 at both corners on the back surface side of the horizontal direction moving member 41a. Therefore, the main moving means 4a can be moved smoothly.

Next, the operation of the board support means 32 will be described.
As shown in FIG. 12 (b), the board support means 32 is configured so that the wedge 3221 of the locking member 322 biased in the front direction is engaged with the locking groove 3215 of the right arm 3212, so that the contact roller The state where the left arm 3211 places the gypsum board 10 can be maintained until 455 hits the abutting portion 3222.

FIG. 13 is a schematic enlarged view of the main part for explaining the operation of the board support means of the board cutting machine according to one embodiment of the present invention, and (a) shows a state in which the locking member has released the locking. FIG. 5B is a top view showing a state in which the support member is locked by the locking member after the support member is rotated.
In FIG. 9A, the locking member 322 has a contact portion 3222 that contacts the contact roller 455 and the substrate 412 that move in the left direction, and moves to the back side by the cam mechanism. It will come off the locking groove 3215 of 3212 and will be in a rotatable state. Subsequently, when the contact roller 455 contacts the curved surface 3214 of the left arm 3211, although not shown, the rotatable support member 321 is pushed by the contact roller 455 and rotates clockwise, The stepped portion 3213 of the right arm 3212 moves to the lower part of the gypsum board 10 to place the gypsum board 10. In addition, when the support member 321 rotates, the mounting roller 454 supports the gypsum board 10 that is temporarily not supported.

  Next, as shown in FIG. 13B, when the substrate 412 moving in the left direction and the contact roller 455 pass through the contact portion 3222, the locking member 322 is moved to the front side by the biasing force of a spring (not shown). Since it moves, the wedge 3221 is engaged with the locking groove 3215 of the left arm 3212 to lock the support member 321. In addition, when the horizontal direction moving member 41a moves from left to right, it can move right without any trouble by returning to the above operation. That is, although the board support means 32 is supporting the gypsum board 10 from the back surface direction, the horizontal direction moving member 41a which moves the back surface side of the gypsum board 10 can pass through without trouble.

  The board back support means 35 is different from the board support means 32 in that the stepped portion 3212 is not provided. That is, the board back support means 35 can support the gypsum board 10 from the back surface side at the tip end surfaces of the arms 3211 and 3212, and the back side of the gypsum board 10, similarly to the board support means 32 described above. The horizontal direction moving member 41a that moves is configured such that it can pass without hindrance.

Next, the horizontal cutting operation of the board cutting machine 1 configured as described above will be described with reference to the drawings.
FIG. 14 is a schematic view of a main part for explaining a state in which the board cutting machine according to one embodiment of the present invention cuts the gypsum board in the horizontal direction, and (a) is a perspective view of the state before cutting. (B) shows a perspective view during cutting.
In the figure, in the board cutting machine 1, the moving means 4 is moved to the right end, the gypsum board 10 is placed on the stepped portion 3213 of the board supporting means 32, and is supported by the board backing support means 35 from the back side. In the state, it rests on the mounting table 3. In this way, the board cutting machine 1 can save the installation space and work space of the board cutting machine 1, and can work in a posture in which the worker stands, thus reducing physical fatigue. be able to.
For easy understanding, the slave moving means 4b and the cutting means 2b are omitted.

In the board cutting machine 1, the cutting direction switching lever 224 is rotated in the counterclockwise direction, and the cutting blade 21 and the chamfering blade 25 are fixed to the vertical moving plate 45 in a state of facing the horizontal direction. Therefore, it is possible to prevent a problem that the cutting direction is shifted during cutting.
Further, the cutting direction switching lever 224 is moved up and down to adjust the vertical positions of the cutting blade 21 and the chamfering blade 25, and the vertical moving plate 45 is fixed to the horizontal moving member 41a. Thereby, since the vertical direction moving plate 45 does not move during cutting, the gypsum board 10 can be accurately cut in the horizontal direction.

  After the cutting blade 21 and the chamfering blade 25 have been set in the cutting direction and the vertical position, when the moving means 4 is moved to the left, the gypsum board 10 is moved to the front as shown in FIG. From the side, it is chamfered by the chamfering cutter 25 and from the back side by the cutting cutter 21. That is, by moving the moving means 4 to the left side, the gypsum board 10 can be cut in a chamfered state, and work efficiency can be greatly improved.

Next, the cutting operation in the vertical direction of the board cutting machine 1 configured as described above will be described with reference to the drawings.
FIG. 15: is the schematic of the principal part for demonstrating the state which the board cutting machine which concerns on one Embodiment of this invention cut | disconnects a gypsum board to a perpendicular direction, (a) is a perspective view of the state before a cutting | disconnection. (B) shows a perspective view during cutting.
In FIG. 2A, the gypsum board 10 is placed on the stepped portion 3213 of the board support means 32 and is laid on the placement table 3 while being supported by the board back support means 35 from the back side.
For easy understanding, the slave moving means 4b and the cutting means 2b are omitted.

The state of FIG. 15A is performed by the following work, although not shown.
First, in the board cutting machine 1, the moving means 4 is moved to the right end, the cutting direction switching lever 224 is rotated clockwise, and the cutting blade 21 and the chamfering blade 25 are oriented in the vertical direction. It is fixed to the vertical movement plate 45.
Subsequently, after raising the cutting direction switching lever 224 to a height at which the cutting blade 21 and the chamfering blade 25 do not contact the gypsum board 10, the moving means 4 is moved leftward to adjust the horizontal position, The horizontal movement member 41 a is fixed to the mounting table 3. Thereby, since the horizontal direction moving member 41a does not move in the horizontal direction during cutting, the gypsum board 10 can be accurately cut in the vertical direction.

  After the cutting direction and the horizontal position of the cutting blade 21 and the chamfering blade 25 are set, when the vertical direction moving plate 45 is moved downward, as shown in FIG. From the front side, the chamfering blade 25 is chamfered, and from the back side, the cutting blade 21 is cut. That is, by moving the moving means 4 downward, the gypsum board 10 can be cut in a chamfered state, and work efficiency can be greatly improved.

  Thus, according to the board cutting machine 1 according to the present embodiment, the plaster board 10 in a standing state can be cut in the horizontal direction and the vertical direction and the chamfering of the cutting portion can be performed collectively. Workability can be greatly improved. In addition, since it is possible to work in an easy working posture in a standing state, it is possible to reduce the physical fatigue of the worker and to save space in the work place.

The board cutting machine of the present invention has been described with reference to the preferred embodiment. However, the board cutting machine according to the present invention is not limited to the above-described embodiment, and various modifications can be made within the scope of the present invention. It goes without saying that implementation is possible.
For example, the board cutting machine 1 is configured to move the cutting blade 21 and the chamfering blade 25 with respect to the gypsum board 10 by moving the moving means 4, but the moving means 4 is fixed and the gypsum board is fixed. The gypsum board 10 may be cut and chamfered by pushing 10 between the cutting blade 21 and the chamfering blade 25.
Moreover, it is good to provide the hook-shaped horizontal direction clamp 36 (refer FIG.1 and FIG.11 (a)) which supports so that the gypsum board 10 may not move to a horizontal direction so that attachment to the vertical direction and the left-right frame 31 is possible, By doing so, it is possible to avoid the problem that the cutting means 2 interferes with the horizontal presser 36.

  Furthermore, the board cutting machine 1 may be configured to include a tilting unit that tilts the board cutting machine 1 in the cutting direction. As shown in FIG. 16, the inclination means includes a square pipe 31a in which the right end portions of the rail 411 and the beam members 320 and 350 are welded, and the square pipe 31a to the columnar member 31b of the right frame 31. It consists of a bolt (not shown) that can be freely changed in position. In this way, the board cutting machine 1 is inclined obliquely upward to the right by sliding the right frame 31 downward (lifting the square pipe 31a upward) and fixing the square pipe 31a to the columnar member 31b. Can be installed in the state. Accordingly, when the gypsum board 10 is cut in the horizontal direction, the moving means 4 (not shown) can be cut while being lowered from the upper right to the lower left, so that it can be easily cut using gravity. . In addition, it is possible to effectively prevent the board cutting machine 1 from slipping leftward during cutting.

  As described above, the board cutting machine of the present invention is not limited to the cutting of gypsum board, and can be widely applied to, for example, cutting of wooden or resin plate members.
