Description

[Detailed description of the invention]

0001

[Industrial Application Field] When cutting plate-shaped objects such as flat roofing materials, tiles, and flooring materials, the present invention enables efficient cutting by fixing the cutting point in an accurately positioned state. This invention relates to a workbench for cutting plate-shaped objects.

0002

[Background Art] Conventionally, when cutting a predetermined portion of a plate-like object using an electric cutter, a black line is drawn on the cut portion of the plate-like object, and then the electric cutter is moved along the ink line. Alternatively, the electric cutter is moved by applying an auxiliary ruler to the cut portion and moving the electric cutter along the ruler.

0003

[Problem to be Solved by the Invention] However, in the case of the former cutting process, it is difficult to move the electric cutter accurately along the ink line, and the electric cutter may deviate from the ink line, making it difficult to cut with high precision. There may be cases where it becomes impossible to
Furthermore, there is a problem in that cutting efficiency is reduced because the operator must move the electric cutter while visually checking the cutter plate of the electric cutter and the ink lines.

On the other hand, even when cutting is carried out by applying an auxiliary ruler to the cutting position as in the latter case, the auxiliary ruler cannot be securely fixed and may shift during cutting, or the electric cutter may The auxiliary ruler may be displaced from the auxiliary ruler, making it difficult to cut accurately. Furthermore, the auxiliary ruler may be damaged by the electric cutter, and in any case, accurate cutting cannot be performed.

[0005] In addition, with any of the cutting methods, for example, when constructing roofing materials on-site, it is difficult to cut on a sloping roof, and furthermore, cutting waste is scattered during cutting. This dust not only worsens the working environment, but also causes problems such as the dust adhering to the coating surface of the roofing material, causing a whitening phenomenon and, in the worst case, requiring repainting.

The present invention has been made in view of these problems, and it is possible to securely fix a plate-like object so that it can be cut along a predetermined cutting line even if the cutting work area is inclined. To provide a workbench for cutting a plate-shaped object, which can easily and accurately perform the cutting operation, and can effectively suck and remove dust from cut chips.

Further, a cutting positioning frame material provided with a ruler piece 9 that matches the locus of movement of the cutting blade of the electric cutter that moves along the guide member 2 is placed on the cutting jig table. It has a removable structure.

[0008] Furthermore, in such a workbench for cutting a plate-shaped object, as described in claims 2 and 3 above,
A slit leading to the back surface of the base plate is bored in the cutting blade passage groove provided on the plate-like object mounting base plate, and this slit is communicated with a dust intake chamber provided integrally at the center of the lower face of the base plate. A suction pipe was connected to the dust intake chamber, and plates for fixing the end face of the plate-like object were arranged at several places on both sides of the plate-like object mounting base, and the end-face fixing plates were inserted into appropriate places. It has a structure in which the enlarged head of the bolt body is movably engaged in a guide groove recessed in the width direction of the plate-shaped object mounting base, and a nut body is screwed into the upper end of the bolt body.

[Operation] First, if the workplace is sloped, install a support base on the slope, and then move the plate-like object mounting base upwards against the support base until the base becomes a horizontal surface. Stand up and hold in that position. After that, the plate-like object to be cut is placed on this platform, and the cutting jig table is stacked on top of it, and the ruler piece of the cutting positioning frame material is brought into contact with the plate-like object through the central through hole. .

[0010] Next, the plate-like object is moved horizontally on the base plate so that its cutting line matches the ruler piece, and is fixed in this state. This fixing means involves moving a plurality of end face fixing plates disposed on the base plate along the guide groove to bring them into contact with the end face of the plate-like object, and then screwing the nut body in this state. The end face fixing plate is fixed at that position to clamp the plate-like object.

[0011] After that, the ruler piece is removed, and then an electric cutter is placed between the guide members of the cutting jig table and moved along the guide members, and the movement locus of the cutting blade follows the ruler piece. Since the cutting line is aligned with the cutting line, the plate-shaped object can be accurately cut along the cutting line. Dust, which is cutting debris, is collected by generating suction force through a suction pipe in the dust intake chamber provided on the back side of the plate-shaped object mounting table, and then passing through the cutting blade passage groove provided on the upper surface of the plate-shaped object mounting table.

It is configured so that

[0024] In order to cut a plate-shaped object A such as a plate-shaped roof tile using the workbench for cutting plate-shaped objects constructed as described above, first, the tile material (plate-shaped object) is cut on the roof of a house. In the case of construction, as shown in FIG. 8, when the plate-like object mounting base 2 is stacked on the support base 1, it is installed in an inclined state. Stand up and fix it in a horizontal position.

That is, when the plate-like object mounting base 2 is rotated upward with respect to the support base 1 installed on the roof, the drawer rod 32 of the angle adjustment mechanism 3 is pulled out from the support rod 31, and the plate If you let go of the object mounting base 2 after rotating it to a horizontal position,
The plate-shaped object mounting base 2 is fixed in a state where the engaging teeth 35 of the drawer rod 32 are engaged with the engaging teeth 34 of the support rod 31 at appropriate positions. When the locking member 33 is moved toward the meshing portion along the support rod 31 in this state, the wedge-shaped protrusion 36 presses the upper end surface of the support rod 31 to lock the engagement teeth 35 to the meshing teeth 34. It is maintained in the same state.

In this way, when cutting a plate-like object on a sloped surface such as a roof, the plate-like object mounting base 2 is adjusted and fixed in a horizontal state, and the supporting base is The support base 1 is fixed at that position by connecting a rope (not shown) to the mounting brackets 12, 12 fixed to one end surface of the support base 1 and fixing the rope in place. Of course, when working on a horizontal surface such as a floor surface, the plate-shaped object mounting base 2 may be superimposed on the support base 1.

After the plate-like object mounting base 2 is thus set in a horizontal state, the plate-like object A to be cut is placed on the plate-like object mounting base 2, and then, as shown in FIGS. 3 and 4, As shown, the cutting jig table 4 is placed on top of the plate-shaped object A, and the cutting positioning frame material 5 is placed on top of the plate-shaped object A. Place it in contact with the top. In this state, by horizontally moving the plate-like object A on the mounting base 2, a cutting line B drawn in advance on the top surface of the plate-like object A, or a cutting line B drawn by a marking line, etc., is drawn on the ruler piece 53. Match the tip edge.

Note that in advance, the fixing nut 56 of the ruler piece 53 attached between the arm members 52, 52 is loosened, and the ruler piece 53 is moved along the elongated holes 54, 54 of the arm members 52, 52. After adjusting the mounting position so that the straight edge of the tip of the piece 53 matches the linear movement locus of the cutting blade 73 of the electric cutter 7, which moves while being guided by the guide members 42, 42 of the cutting jig table 4, , and is fixed by screwing a nut 56.

After that, the end face fixing plate 6 is inserted into the guide groove 26.

The end face fixing plate 6 has guide grooves 26 at several locations corresponding to positions where at least both end faces of the plate-like object A on the mounting base 2 can be clamped and the plate-like object A can be fixed so that it does not move. It should be installed on.

The end face fixing plate 6 is provided with center holes 61 and 62 on both sides thereof, and one of the center holes is pivoted to the guide groove 26 of the plate-like object mounting base 2. Therefore, when the respective center holes 61 and 62 are pivotally supported, the angle and positional relationship of each side of the end face fixing plate 6 with respect to the end face of the plate-like object A can be varied variously. According to the size and shape of the object A, it can be installed in a usage state that is most easily supported.

After fixing the plate-like object A, the cutting positioning frame material 5 is raised upward and then removed from the cutting jig table 4 by tilting it to one side of the support base 1 (FIG. 4). Thereafter, as shown in FIGS. 6 and 7, an electric cutter 7 is attached to one end of the cutting jig table 4 between the guide members 42 and 42.
The cutting blade 7 of the electric cutter 7 is fitted and placed on the surface plate 71 of the electric cutter 7.
3 while rotating the cutter 7 through the guide members 42, 4.
2 and moved in the length direction of the through hole 43, the cutting blade 73 accurately cuts the section of the plate-like object A along the cutting line B.

During this cutting operation, by operating the exhaust motor 10 of the dust collection box 9, the branch pipe 8 of the suction hose 8 is removed.
1 and 82 to generate suction force in the elongated hole 74 of the electric cutter 7 and inside the suction box 23 attached to the bottom surface of the plate-shaped object mounting base 2, and to remove the dust, which is the cutting waste of the plate-shaped object A, for a long time. It is absorbed into one branch pipe 81 through the hole 74, and the suction box 2 is absorbed through the slit 25 of the plate-shaped object mounting base 2.
3 into the other branch pipe 82 and collected from the suction hose 8 into the dust collection chamber 91 of the dust collection box 9.

After cutting a predetermined portion of one plate-like object A in this way, the next plate-like object A is cut in the same manner as described above, but the cutting of the plurality of plate-like objects A to be cut is If the wires are provided in the same part, attachment/detachment to/from the mounting base 2 can be done by using any end fixing plate without loosening the nuts 69 of all the end fixing plates 6 that clamp and fix the plate-like object A. 6
Loosen the nut 69 so that it can be removed slightly,
By bringing the end face of the next plate-like object A into contact with the other fixing plate 6, the positioning of the cutting line as described above can be quickly performed.

[0034] Furthermore, if the plate-like material A to be cut is a roofing material to be installed on a corner ridge of a roof, the joining end surfaces of the roofing materials on both sides that are joined at the ridgeline of the ridge are not vertical planes, but from the surface. They are joined in surface contact only after they are formed on the inclined end surfaces that are inclined diagonally inward toward the back surface. Therefore, when cutting such roofing materials, the surface plate 71 of the electric cutter 7 is rotated in the left-right direction so that it has the same inclination angle as the inclined end surface with respect to the vertical direction of the cutting blade 73. Thereafter, the surface plate 71 may be fixed, and then the cutting blade 73 may cut the surface plate 71 while moving the surface plate 71 using the guide members 42, 42 as a guide as described above.

[0035]

As described above, according to the workbench for cutting plate-like objects of the present invention, after placing the plate-like object to be cut on the mounting base, the cutting jig stand is stacked on top of it. By moving the electric cutter along the guide member provided on the jig stand, it becomes possible to cut a plate-shaped object easily and efficiently.

Furthermore, prior to this cutting operation, a cutting positioning frame member provided with a ruler piece 9 that matches the locus of movement of the cutting blade of the electric cutter that moves along the guide member 2 is inserted through the through hole between the guide members. Since it is configured to come into contact with a plate-shaped object, the cutting point of the plate-shaped object can be set easily and accurately, and a large number of plate-shaped objects can be cut one after another in an orderly manner.

In addition, plates for fixing the end faces of plate-like objects are arranged at several places on both sides of the plate-like object mounting base, and the enlarged head of the bolt body inserted through the end-face fixing plate is inserted into the appropriate position of the plate-like object. By movably engaging the guide groove recessed in the width direction of the mounting base and screwing the nut body onto the upper end of the bolt body, the plate-like object with the cut point set can be easily attached to the plate-like object. It can be firmly fixed in the state, the fixing work can be done quickly, and cutting can be performed with high precision.

Furthermore, a slit that communicates with the back surface of the plate-shaped object mounting plate is formed in the cutting blade passage groove provided in the longitudinal direction of the central part of the plate-shaped object mounting plate, and this slit is connected to the cutting blade passage groove provided in the longitudinal direction of the central portion of the plate-shaped object mounting plate. By communicating with the dust intake chamber integrally provided in the center of the lower surface and connecting the suction pipe to the dust intake chamber, it is possible to suction and remove dust generated during cutting without scattering it. This not only improves the working environment, but also prevents any adverse effects on the plate-shaped objects. Furthermore, even on a sloped surface such as a roof, after installing a support base on the slope, move the plate-like object mounting base upwards with respect to this support base until the base becomes a horizontal surface. By standing it upright and fixing it in that state, you can perform cutting operations as smoothly as on a flat surface.
