Description

[Detailed Description of the Invention] [Industrial Application Field] The purpose of the present invention is to create a six-sided box such as a speaker box by using a pair of processed board materials that are formed in series through bending grooves. This invention relates to a method for forming a six-sided box assembled with two plates.

[Prior art and its problems] In the past, in the toning treatment of the board joining edge of the board material used for box forming using particle board, veneer plywood, aluminum board, gypsum board, etc. , usually a simple butt with a 45 degree angle edge surface is planned, and a constant angle cut with the same saw blade or the like is planned.

However, in such a method, the joint of the toe edges is not always sufficient when an external force is applied to the toe surfaces, and misalignment is likely to occur when the toe faces are aligned during box installation, etc., which often results in This is what caused the food accident at the edge of the tome.

In addition, even when cutting the toe surface at such a fixed angle, the wall thickness of the board material is uneven, and the board materials that are connected to each other are cut, while the decorative surface of the board material is used as the surface plate surface, and On the other hand, since the non-decorative back surface of the board material is used as a surface plate surface, this often causes the problem that the edges of the cutting board materials are not perfectly aligned.

[Means for Solving the Problems] The method for forming a six-sided box assembled with two boards according to the present invention was specially devised in view of the inconveniences in the conventional precedent, and the method for forming a six-sided box assembled with two boards is specially devised in view of the inconveniences in the conventional precedent. In addition to creating stepped surfaces that engage with each other, the decorative surfaces of the board material are both made into surface plate surfaces by cutting the toe surfaces, and under the same conditions, one side of the board material that is suctioned and fixed to the surface plate is placed on the upper surface. The other is cut and shaped by abutting a stepped cutting saw blade from the lower side to particularly enhance the mutual joining precision and to reliably prevent unexpected displacement of the joining surfaces. , the gist of its structure is a board material 1 having laminated decorative sheets 1a, 1'a,
1', leaving the decorative sheets 1a and 1'a at the bottom corner 90
A pair of V-grooves with the same dimensions are cut inward from both sides of the board material, and the decorative sheet 1a
Cutting or cutting the circumferential edge of one of the board materials 1 that is attached with its surface in close contact with the surface plate surface from the outside downward direction to the inside upward direction of the fixed board material 1,
On the circumferential side of the board material 1, there is a lower tome surface at an angle of 90 degrees -α upward from the lower edge, and the tome surface that reaches the upper edge of the board via a rising step wall perpendicular to this toe surface. At the same time, the peripheral edge of the other board material 1', which is attached with the decorative sheet 1'a surface in close contact with the surface plate surface, is formed from the inner upper side of the fixed board material 1'. The board is cut or cut outwardly downward, and the board is attached to the circumferential side of the board 1 through an upper toe surface of 90 degrees -α downward from the upper edge and a rising step wall perpendicular to this toe surface. A pair of U-shaped board materials 1, which are simultaneously formed with a lower toe surface parallel to the toe surface reaching the lower edge, and then bent through the V groove;
1' with a phase of 90 degrees to each other, board materials 1,
1', the upper toe surfaces, the lower toe surfaces, and the step walls are brought into contact with each other and assembled.

[Example] Hereinafter, a typical example of a machine for forming the joint edge of a six-sided box construction board according to the present invention will be described with reference to the attached drawings of FIGS. 7 and 8. , the processing machine shown in this drawing is used for cutting a joint surface along a longitudinal side edge of a board material 1.

The processing machine 2 includes a pair of surface plates 3, 3' having suction holes 3a, 3'a formed therein so that the pair of board materials 1, 1' forming the box a can be simultaneously processed. A board 1, 1', which is a processing material, is placed on the surface plate 3, 3' with its decorative surface facing the surface plate 3, 3'. A separately prepared suction blower 4 connected to the lower surface by a flexible pipe (not shown) or the like is used to attract and position the surface plates 3 and 3'.

These surface plates 3, 3' are installed on table surfaces 6, 6' that are erected on the table frame 5, and have a pair of table running rails 7, 7' and guides on these rails 7, 7'. It has rollers 8 and 8' to allow it to run freely, and a hydraulic cylinder 9 to enable movement of the processing machine 2 in the front and rear directions.

The table running rails 7, 7' are particularly designed as a pair of chevron-shaped rails to provide good running characteristics and reliably prevent wobbling, waving, etc. on the surfaces of the surface plates 3, 3' during running. The positions of the mounting shafts of the guide rollers 8, 8' on the roller 7' can be freely adjusted, making it possible to accurately level the surfaces of the surface plates 3, 3'.

A frame 10 for attaching a saw or a cutter unit or the like is provided perpendicularly to the moving mechanism and straddling the moving mechanism for the moving mechanism of the surface plates 3, 3'. Alternatively, the cutter units 11, 11' are mounted.

Therefore, these cutter units 11,1

1'c, etc., hanging from the frame 10, saws or cutters 11C, 11'c are tilted to the side of the surface plates 3, 3' at a predetermined angle, and handles 11d, 11'd are used to control the vertical positions thereof. It is to be adjusted accordingly.

Incidentally, these saws or cutter units 11, 1
Sliding, fastening, or changing the angle of attachment to the saw or cutter 11c, 11'c on the frame 10 of 1' are, of course, accomplished by appropriate methods.

In the figure, reference numeral 12 indicates a hydraulic system that controls the hydraulic cylinder 9.

In particular, the processing machine 2 having such a configuration simultaneously processes the pair of board materials 1 and 1' constituting the box a.
In other words, the main purpose is to process under the same conditions, and by molding the toe surfaces that engage with each other simultaneously under the same conditions, it eliminates molding dimensional errors and ensures tight contact and no mutual deviation. The purpose is to create a tome surface.

With this intention, the board materials 1 and 1' are supplied to the surface plates 3 and 3' so that the decorative surfaces are adsorbed, and the saw or cutter 11c of the unit 11 is used to cut the non-decorative surface of the board material 1 from the lower side of the surface plate 3. The board material 1 is chamfered from its decorative surface to its non-decorative surface, and then the saw or cutter 11'c of the other unit 11' is placed in the upper side of the surface plate 3'. It is arranged so as to be more inclined toward the surface plate 3', and the board material 1' is chamfered from the non-decorative surface to the decorative surface.

This method uses the board decorative surface having a particularly smooth horizontal end surface as a reference surface, and uses the same saw or cutter 11 to ensure strict processing accuracy.
The purpose of this invention is to enable alternative use of the parts 11 and 11'c in either of the units 11 and 11', and to reliably prevent poor adhesion of the toe surfaces due to different shapes of saws or cutters.

That is, the same saw or cutter 11c, 11'c

As shown in FIG. 8, the units 11 and 11' are mounted in pairs at the front and rear of the frame 10 so that they can be moved and adjusted. It is specially designed to be compatible with tome surface treatment.

Next, the processing machine 2' shown in Figs. 9 and 10 is used for cutting the board materials 1, 1' in the short dimension direction, and the processing machine 2' shown in Figs. The structure is exactly the same as that shown in FIGS. 7 and 8, and the board materials 1 and 1' are intended to be cut under the same conditions.

In this processing machine 2', a V-groove machining blade 1 having a blade angle of approximately 45 degrees is used to perform the bending V-groove machining of the board materials 1, 1' at the same time as this toe surface treatment.
1e and 11'e are arranged perpendicularly to the units 11 and 11', and the thick parts of the boards are set at a constant angle, leaving the decorative sheets 1a and 1'a on the surfaces of the board materials 1 and 1'.
The V-cut is made at 90 degrees, and by applying such processing, it is possible to improve the work efficiency at the stage of assembling the six-sided box.

That is, as described above, the surface decorative sheets 1a, 1'
Since the box is bent around point a, it is possible to avoid misalignment during the adhesion stage of the toe surface and create an accurate raised surface compared to the case where the box corner surfaces are manufactured individually.

Note that the tome surfaces formed on the board materials 1 and 1' mesh with each other as shown in FIG.
is 90 degrees, angles c and d are 135 degrees ±α, and angles e and f are 45 degrees ±α, and a suitable saw blade is used so that the lower tome surface and the upper tome surface are parallel to each other, for example, as shown in FIG. It was planned to use a saw blade.
