2. Description of the Related Art Generally, a box-shaped body having a panel structure is prepared by first preparing a panel consisting of a surface plate and a core material for each surface,
Although it was formed by assembling each panel like this in a box shape via a frame, the manufacturing cost, dimensional accuracy,
Recently, the following materials have been developed in order to improve the adhesive strength, watertightness, etc. That is, FIG. 3 shows an example of such a box-shaped body, (1) is an overall perspective view, (2)
The figure is a cross-sectional view of the main part before bending, and (3) is the cross-sectional view of the main part after bending. The box-shaped body 1 having the panel P structure which has been recently developed has a continuous outer surface plate 2, a core material 3 on each surface adhered to the inner side of the surface board 2, and a corner between the core materials 3. And a frame 4 to be formed, and was molded as follows. That is, first, with respect to the outer surface plate 2 prepared in a linear and flat state as a whole,
After adhering the core material 3, the inner surface plate 5, the frame 4, etc. of each surface while sequentially positioning them in the longitudinal direction in a predetermined positional relationship (shown in phantom lines in FIG. (2) Refer to the drawing), with respect to such a panel P, a pressing force is applied to the surface plate 2 from the outside, and the outside surface plate 2 is bent along the bending of each frame 4 between the inner core materials 3. As a result, the box-shaped body 1 was formed (see FIG. 3 (3)) (see the solid line in FIG. 3 (1)). Conventionally, such bending and forming has been performed manually.

[0003]

By the way, the following problems have been pointed out in such a conventional example. That is, conventionally, as described above, since the box-shaped body 1 is formed by manually bending the surface plate 2 of the panel P, firstly, the bending work is not easy, and thus the box-shaped body 1 is not easily formed. However, there is a problem in that a great amount of labor is required for the molding.
Secondly, especially when the width of the panel P is wide, that is, the surface plate 2
It has been pointed out that it is almost impossible to bend the surface plate 2 with a uniform force at the same time when it is long in the short-side direction, which makes the bending work extremely difficult and inaccurate. Thirdly, in such bending, usually, the face plate 2 at the corner of the panel P is
Adhesion between the frame 4 and the core material 3 is performed, and the bent state is fixed. By the way, it is necessary to keep the bent state of the surface plate 2 as it is until the adhesive A for bonding is cured, but it is not easy to hold the bent state by hand, and thus the box-shaped It has also been pointed out that a great amount of labor is required to mold the body 1.

In view of such circumstances, the present invention has been made to solve the problems of the above-mentioned conventional example, and is provided with a predetermined pedestal, a roller and a positioning movement mechanism, and the roller is provided at a corner of the pedestal. Since the continuous surface plate of the panel is bent along the bending of the frame by moving the plate while positioning and pressing it near the portion,
In addition, the bending of the face plate is facilitated, and secondly, even when the width of the panel is wide, accurate bending can be simultaneously performed with a uniform force. Thirdly, the bending state during the curing time of the adhesive is further improved. It is an object of the present invention to propose a panel bending device capable of easily holding a panel.

That is, this panel bending apparatus includes a continuous surface plate, a core material on each surface adhered to the inside of the surface plate, and a frame located at a corner between the core materials. Used when forming a box-shaped body. The pedestal includes a pedestal having a corner corresponding to the inner corner of the box-shaped body, a roller arranged near the corner of the pedestal, and a positioning movement mechanism for the roller. Then, the roller is press-contacted from the outside to the surface plate placed on the pedestal and prepared in advance in a generally flat state with each core material or frame, and through the frame inside the surface plate. The surface plate can be bent along the bending of the frame while being positioned toward the corner portion and applying a pressing force to the surface plate while moving.

[0006]

Since the present invention comprises such means, it operates as follows. That is, first, a continuous integrally molded panel is prepared in advance, in which the core material of each surface is positioned and adhered to the surface plate in a continuous flat state through the frame of the edge and a slight gap, Such a panel
The frame is mounted on the pedestal of the panel bending device so that the frame is located so as to project at the corner. Then, the roller is brought into pressure contact with the surface plate of the panel from the outside by the positioning movement mechanism, and is positioned toward the corner portion of the pedestal through the frame inside the surface plate. Then, the roller is moved around the frame by the positioning movement mechanism, and a pressing force is applied to the surface plate, so that the surface plate is bent along the bending of the frame to form a box-shaped body.

Then, in the panel bending apparatus of the present invention, firstly, the surface plate of the panel is easily bent by moving the rollers while positioning them by the positioning moving mechanism on the pedestal. Therefore, secondly, even when the width of the panel is wide, the accurate bending of the surface plate can be realized simultaneously with a uniform force by the rollers, the positioning movement mechanism, the pedestal and the like. Third, even when the surface plate, frame, and core material are bonded to each other at the corners of the panel, the positioning and fixing of the roller by the positioning movement mechanism makes it easy to keep the bent surface plate during the adhesive curing time. Can be held at.

In FIG. 3 (1), 7 is a joint between the panels P. Thereafter, such a panel P is bent by applying a pressing force from the outside using the next panel bending device 6 (shown in phantom lines in FIG. 3 (1), FIG. 3). (2) Figure, (3) Figure in Figure 3), Panel P
The box-shaped body 1 having the structure is formed (see the solid line display in FIG. 3A). Such a box-shaped body 1 is used as a cart in which articles are stored and various services are provided by further adding a door, a back plate, casters and the like.

As shown in FIGS. 1 and 2, the panel bending apparatus 6 has the following pedestal 8, roller 9 and positioning movement mechanism 10. First pedestal 8
Is provided with a corner portion 11 corresponding to a right-angled corner shape inside the box-shaped body 1 (see FIG. 3 (1)). In the illustrated example, the upper surface of the pedestal 8 is one of the panels P. The core material 3, for example, has an area corresponding to the size of the core material 3 on the side surface or the upper and lower surfaces, and corner portions 11 are formed at right angles on the left and right at intervals corresponding to the length of one side of the core material 3. ing.

Next, the roller 9 of the panel bending apparatus 6
In the illustrated example, a pair of positioning moving mechanisms 10 are provided on the left and right sides, and each has a flat plate-like guide portion 12 fixed to the front and rear of the pedestal 8 and a guide hole 13 vertically provided on the guide portion 12. A fulcrum pin 14 that can move up and down in the guide hole 13, a handle 15 having one end (lower end) rotatably attached to and held by the fulcrum pin 14, and the other end (upper end) of such front and rear handles 15. And a handle shaft 16 for connecting the two.

The roller 9 has front and rear handles 15 for the left and right positioning and moving mechanisms 10, respectively.
Around the fulcrum pin 14 from the center of the above, it is hung horizontally around the rotary shaft 17 so as to be rotatable around the rotary shaft 17. The roller 9 is arranged near the corner portion 11 of the pedestal 8 and can be pressed against the surface plate 2 of the panel P placed on the pedestal 8 from the outside. Along with this, the roller 9 is positioned toward the corner portion 11 of the pedestal 8 via the frame 4 inside the surface plate 2 that is pressed against the roller 9, and while moving, applies a pressing force to the surface plate 2 to move the surface plate 2 to the frame 4. It can be bent along a curved line. The pressure contact, the positioning, the movement, etc. of the roller 9 are realized by the horizontal swinging around the fulcrum pin 14 of the handle 15 of the positioning movement mechanism 10, the vertical movement of the handle 15 along the guide hole 13, and the like. To be done. In addition, such a positioning movement mechanism 10 of the roller 9 is
Of course, the present invention is not limited to the method using the fulcrum pin 14 and the handle 15 in the illustrated example, and various other methods that realize predetermined pressure contact, positioning, movement, etc. of the roller 9 may be adopted.

The present invention is constructed as described above.
Then it becomes as follows. First, two consecutive linear and flat outer surface plates are paired with each other, and the core material 3 on each surface is longitudinally arranged in a predetermined positional relationship with the frame 4 at the end edges and a slight interval. A panel P with a frame 4 that is continuously integrally molded and is sequentially positioned and bonded is prepared in advance. In the illustrated example, a panel P in which an inner surface plate 5 is further bonded to each core material 3 is prepared. Then, such a panel P is placed on the pedestal 8 of the panel bending device 6. The panel bending device 6 is provided with a predetermined pedestal 8, a roller 9 and a positioning movement mechanism 10, and has a panel P.
Is mounted on the pedestal 8 of such a panel bending device 6 so that the frame 4 between the core members 3 is located at the corner portion 11 so as to project. Then, the roller 9 is brought into pressure contact with the surface plate 2 of the panel P from the outside by the positioning movement mechanism 10, and is positioned toward the corner portion 11 of the pedestal 8 via the frame 4 inside the surface plate 2. Then, the roller 9 is moved around the frame 4 by the positioning movement mechanism 10 to apply a pressing force to the surface plate 2 of the panel P, thereby bending the surface plate 2 along the bending of the frame 4. The box-shaped body 1 is molded.

To explain these points in more detail, first, as shown in FIG. 2 (1), the panel P is placed so that the predetermined core material 3 is located on the pedestal 8 and left and right. The frames 4 are set so as to project from the left and right corner portions 11, respectively. Then, the left and right rollers 9 are positioned and pressure-contacted to the frame 4 of such a panel P via the surface plate 2. Next, as shown in FIG. 2 (2),
By gradually swinging the handle 15 of the left and right positioning moving mechanism 10 from the standing state to the left and right around the fulcrum pin 14, the rollers 9 are respectively rotated.
While rotating around 7 as a center, it moves around the frame 4 via the surface plate 2 in the state of positioning pressure contact. As a result, a pressing force is applied to the surface plate 2 between the roller 9 and the frame 4, and the surface plate 2 is bent along the bending of the left and right frames 4. Further, as shown in FIG. 2 (3), while the handle 15 of the left and right positioning movement mechanism 10 is tilted to the left and right, the handle 1 and the roller 9 are held together.
5 is lowered along the guide hole 13 via the fulcrum pin 14. As a result, the core material 3 positioned on the left and right sides of the panel P via the surface plate 2 by the roller 9 moves to the side surfaces 18 of the pedestal 8.
They are pressed against each other and positioned and fixed. Therefore, it becomes possible to maintain the above-described bent state of the surface plate 2 along the frame 4 as it is.

As described above, the panel bending device 6 is used when forming the box-shaped body 1 having the panel P structure.
It becomes the second and the third. First, by moving the roller 9 while positioning it by the positioning movement mechanism 10, the surface plate 2 of the panel P is bent along the bending of the frame 4, and the bending is easily performed without manual work. To be done.

Secondly, the width of the panel P is particularly wide,
Even if the lateral direction of the surface plate 2 is long and the depth of the box-shaped body 1 is deep, the roller 9, the positioning movement mechanism 10, the pedestal 8 and the like do not cause difficulties such as manual work, and apply a uniform force. At the same time, accurate bending of the face plate 2 is realized.

Thirdly, in such bending, the surface plate 2, the frame 4 and the core member 3 at the corners of the panel P are formed.
When the bonding between the two is performed and the bent state is fixed, the following is performed. That is, the positioning and fixing of the roller 9 by the positioning and moving mechanism 10 makes it possible to easily hold the bent state of the surface plate 2 as it is during the curing time of the adhesive A without difficulty as in the case of manual work ( See (3) of FIG. 2, (2) of FIG. 3, and (3) of FIG. 3).

[0018]

As described above, the panel bending apparatus according to the present invention is provided with a predetermined pedestal, a roller and a positioning movement mechanism, and moves the roller while positioning and pressing them in the vicinity of a corner of the pedestal. The following effects are exhibited by bending the continuous surface plate of the panel along the bending of the frame.

First, bending of the surface plate of the panel is facilitated. That is, the bending is dramatically facilitated as compared with the conventional manual work, and therefore, the box-shaped body having the panel structure is easily facilitated.

Secondly, especially when the width of the panel is wide,
A uniform force enables accurate bending at the same time. That is, even when the width of the panel is wide, the lateral direction of the surface plate is long, and the depth of the box-shaped body is deep, the bending work does not become difficult unlike the conventional manual work, and uniform force is applied at the same time. Bending is realized.

Thirdly, the bent state can be easily maintained during the curing time of the adhesive. That is, the bent state of the surface plate can be easily maintained as it is until the adhesive between the surface plate, the frame and the core material at the corners of the panel is cured, and the box-shaped body of the panel structure can be formed from this aspect as well. Easy and easy. As described above, the effects of the present invention are remarkably large, such as the problems existing in this type of conventional example are eliminated.
