Description

  The present invention relates to a method for manufacturing a honeycomb panel.

  A honeycomb panel has a simple structure in which a honeycomb core is sandwiched between two face plates, but is lightweight and excellent in soundproofing. Therefore, the honeycomb panel is used for construction as a partition plate or the like. In the case of a transparent acrylic resin plate or the like, it is also used as an interior because of its beauty. Therefore, the honeycomb panel is required not only for the bonding strength between the honeycomb core and the face plate, but also for the flatness and good finish of the honeycomb panel.

  Here, in a general method for manufacturing a honeycomb panel, a method of bonding a honeycomb core to a face plate is performed by applying an adhesive to the entire face plate to which the honeycomb core is bonded, or attaching an adhesive sheet, and bonding the honeycomb core to the face plate. A manufacturing method is known in which an adhesive is cured by a heating device placed on the upper side of an agent or the like.

  And while the size of the face plate bonded to the honeycomb core is generally as large as 900 mm × 1800 mm or 1200 mm × 2500 mm, the thickness is as thin as 1 to 4 mm and easily bends. Therefore, when the honeycomb core and the face plate are bonded, the face plate ensures the flatness of the face plate in a place where the face plate is flat when bonded.

However, even if the flatness of the face plate is ensured, poor adhesion occurs when the thickness of the adhesive applied to the face plate is not uniform as a whole.
In addition, since the adhesive was applied to the entire surface, the adhesive was also applied to the portion that did not adhere to the honeycomb core, which was very wasteful and costly, and the face plate was a transparent acrylic resin In the case of a plate or the like, the adhesive applied to the inside of the face plate also has a problem that aesthetics are impaired due to a decrease in transparency.

Conventionally, in Patent Document 1, an adhesive made of a photo-curing resin is applied directly to the opening of the honeycomb core by a brush, a roller, a spray, or the like, instead of the face plate. A method for manufacturing a honeycomb panel to which a face plate is bonded is described. According to the method, since the adhesive is not applied to the entire surface of the resin plate, the amount of the adhesive can be reduced, and the adhesive is cured by light energy. It is possible to eliminate the need for costly overheating devices.

  However, in the case of a method in which the adhesive is applied only to the bonding surface of the honeycomb core by rollers, sprays, etc., the thickness of the adhesive that adheres to each cell constituting the honeycomb core differs, and the thickness of the adhesive The problem of poor adhesion due to unevenness remains.

  In addition, if a photo-curing adhesive is used, there is a problem that the cost is high and the face plate is limited to a transparent plate.

  Therefore, the present invention was created to solve such problems, and solves the above-described problems and does not impair the adhesive strength, while it has high flatness, is economical, and has a good finish. It is an object of the present invention to provide a method for manufacturing a honeycomb panel that can be used as an object.

  A method for manufacturing a honeycomb panel according to the present invention is a method for manufacturing a honeycomb panel in which two flat face plates facing each other and a honeycomb core disposed between the face plates are integrally formed with an adhesive. The adhesive layer is formed on the flat surface so as to have a uniform thickness, and one end surface of the honeycomb core to be bonded to the face plate is placed on the adhesive layer, and the adhesive By separating the honeycomb core from the layer, an adhesive is attached to the adhesive surface of the honeycomb core.

  According to the method for manufacturing a honeycomb panel according to such a procedure, if the honeycomb core is separated from the adhesive layer in order to place the adhesive surface of the honeycomb core on the adhesive layer having a uniform thickness, the honeycomb panel The thickness of the adhesive that adheres to the adhesive surface of the core is uniform throughout. Moreover, since the adhesive used is only the bonding surface of the honeycomb core, it is possible to cut a useless adhesive. And even if it is a case where a faceplate is a transparent acrylic resin board etc., there is no possibility that the transparency of the surface inside a faceplate may be impaired by an adhesive agent.

  In the honeycomb panel manufacturing method, the surface opposite to the bonding surface of the honeycomb core disposed on the adhesive layer is pressed by a pressing unit that contacts, slides, rolls, or presses. I made it.

  According to the method for manufacturing a honeycomb panel according to such a procedure, the other end surface of the honeycomb core placed on the adhesive layer is pressed by a pressing means such as a roller, so that the honeycomb core deformed by bending or the like is deformed. Even so, it becomes possible to reliably adhere the adhesive having the same thickness to the end faces of the upper and lower openings of the honeycomb core.

  The adhesive layer is formed on a flat plate disposed on the flat surface, and when the honeycomb core is separated from the adhesive layer, the adhesive layer is held on the adhesive layer while holding the honeycomb core. In order to apply force only in the thickness direction, the one end side of the flat plate was turned back to the non-adhered side of the honeycomb core so as to be separated.

  According to the method for manufacturing a honeycomb panel according to such a procedure, the honeycomb core can be peeled off from the adhesive layer with a smaller force than when the entire flat plate is peeled off at once. Further, since the direction in which the peeling force works is only the thickness direction of the adhesive layer, the honeycomb core has no force in the horizontal direction when peeling off, and deformation of the honeycomb core can be prevented, and Deviation of the adhesive itself attached to the honeycomb core can also be suppressed.

  The method for manufacturing a honeycomb panel according to the present invention has the following excellent effects.

  According to the first aspect of the present invention, there is no adhesion failure due to uneven thickness of the adhesive that adheres, and the adhesive strength can be maintained, while economical due to the cutting of excess adhesive. A honeycomb panel can be provided. When the face plate is a transparent acrylic resin plate or the like, there is no fear that the inner surface of the acrylic resin plate or the like has a loss of transparency due to the adhesive, so that a honeycomb panel with good finish can be provided. .

  According to the second aspect of the present invention, even if the honeycomb core is deformed such as bending, it is possible to avoid poor adhesion due to non-adhesion of the adhesive.

  On the other hand, according to the invention of claim 3, it is possible to prevent deformation of the honeycomb core when separating the honeycomb core from the adhesive layer, and displacement of the adhered adhesive having a uniform thickness, Furthermore, it is possible to provide a honeycomb panel having high flatness and good finish.

  A best mode for manufacturing a honeycomb plate of the present invention (hereinafter referred to as “embodiment”) will be described in detail with reference to the drawings.

First, the structure of the honeycomb panel 1 will be described with reference to FIG.
As shown in FIG. 1, the honeycomb panel 1 is formed by fixing two opposing face plates 3a and 3b and a honeycomb core 2 disposed between the two face plates with an adhesive 6b. .
The honeycomb core 2 has a hexagonal shape in plan view and a shape in which a plurality of cells 5 formed to have the same thickness are connected. The cell 5 maintains a cylindrical shape having a hollow portion, and the surfaces of adjacent cells are brought into contact with each other to form one honeycomb core. The material of the honeycomb core may be formed of a metal such as plastic or aluminum, and is not particularly limited. When manufacturing the honeycomb core 2 made of aluminum, it is manufactured by laminating a plurality of aluminum plates, fixing a part of the laminated aluminum plates with an adhesive, and stretching them from both ends. To do.
As the face plates 3a and 3b, for example, a transparent acrylic resin plate may be used as described above, but this does not limit the face plate to an acrylic resin plate, but an aluminum plate, a steel plate, a fiber reinforced plastic plate, or the like. It may be used.
The adhesive 6b is an adhesive that adheres to the adhesive surface of the honeycomb core 2 by separating the honeycomb core 2 and an adhesive layer 6a described later. Both the adhesive layer 6a (see FIG. 2) and the adhesive 6b are used. This is the same adhesive as the adhesive 6 described later.

Next, a method for manufacturing a honeycomb panel will be described with reference to FIG.
First, as shown in FIG. 2A, the adhesive 6 is applied on the flat plate 7 disposed on the flat surface 8. The applied adhesive 6 is not limited to a photocurable resin or the like, and may be an epoxy resin composition used as a general adhesive.
Moreover, although the flat plate 7 illustrated in this embodiment is made of aluminum, it is not limited to this. From the viewpoint of adhesiveness, it is desirable that the flat plate surface be cleaned and dried.

  Next, the adhesive layer 6a is formed by making the adhesive 6 applied on the aluminum flat plate 7 to have a uniform thickness as shown in FIG. 2B. Here, according to the present embodiment, the spatula 9 is used as a member for adjusting the adhesive 6 to a uniform thickness. However, if the member can make the thickness of the adhesive 6 uniform, a roller can be used. Etc.

Next, as shown in FIG. 2C, the honeycomb core 2 is placed on the adhesive layer 6 a, and the adhesive 6 a is attached to the adhesive surface of the honeycomb core 2. Here, it is desirable to place the honeycomb core 2 horizontally with respect to the adhesive layer 6a.
Further, in the honeycomb core 2 in which deformation such as bending occurs in the process of transporting the honeycomb core 2 or the like, even if the honeycomb core 2 is placed on the adhesive layer 6a, a portion not in contact with the adhesive layer 6a is present. Therefore, as shown in FIG. 2 (d), the other side of the honeycomb core 2 to which the adhesive layer 6a is not applied may be lightly pressed by a pressing means. By this method, it becomes possible to adhere an adhesive to the entire surface of the honeycomb core 2. Here, as an example of pressing, the roller 10 is pressed by rolling from one end side of the honeycomb core 2 to the other end side, but is not limited to this, using a flat plate or the like, You may pressurize by pressing the whole honeycomb core surface at once.

  Next, as shown in FIG. 2E, the adhesive layer 6a and the honeycomb core 2 are separated. Here, in order to separate the honeycomb core 2 and the adhesive layer 6a, it is necessary to apply a force. However, when such a force acts in the horizontal direction of the adhesive layer 6a, the honeycomb layer 2 is interposed via the adhesive layer 6a. A force also acts on the core 2 in the horizontal direction, and the shape of the honeycomb core 2 is deformed. Further, the adhesive 6b attached to the honeycomb core 2 is also displaced. However, the displacement of the adhesive 6b causes poor adhesion, and when the face plates 3a and 3b are transparent, the adhesive varies. This also causes the appearance of the honeycomb panel 1 after completion to deteriorate. Hereinafter, a specific method for separating the honeycomb core 2 and the adhesive layer 6a will be described with reference to FIG.

  As shown in FIG. 3 (a), the separation method includes an adhesive layer 6a formed on the flat surface 8 and having a uniform thickness, and a honeycomb core 2 placed on the adhesive layer 6a. Is peeled off in the thickness direction of the adhesive layer 6a. According to this method, the entire honeycomb core 2 may be peeled off at once in the thickness direction of the adhesive layer 6a, and the force for separating the adhesive layer 6a in the horizontal direction does not work. A shift of the layer 6a does not occur. However, according to this method, a large force is required to peel the adhesive layer 6a and the entire honeycomb core 2 at a time, and the honeycomb core 2 is easily deformed with respect to the applied force. Therefore, it is difficult to peel the entire honeycomb core 2 at a time without deformation.

On the other hand, as shown in FIG.3 (b), the adhesive bond layer 6a which forms uniform thickness is arrange | positioned on the flat plate 7 made from aluminum, and the honeycomb core 2 is mounted on the said adhesive bond layer 6a. Then, there is a method in which the adhesive layer 6 a and the honeycomb core 2 are peeled off by turning the aluminum flat plate 7. According to this method, since the force required for peeling off the honeycomb core 2 as a whole as shown in FIG. 3 (a) is small, the load applied to the honeycomb core 2 is small. The deformation of the core 2 can be prevented.
Further, when turning the flat plate 7 made of aluminum, in order to prevent a force from acting in the horizontal direction of the adhesive layer 6a, if the flat plate 7 made of aluminum is folded back, the force at the time of separation is increased. 2 and the deformation of the honeycomb core 2 can be prevented.

  Next, the honeycomb core 2 and the face plate 3a are fixed by an adhesive 6b. As shown in FIG. 2 (f), the honeycomb core 2 is placed on the face plate 3a with the side to which the adhesive 6b is attached, and the adhesive 6b is cured to fix the honeycomb core 2 and the face plate 3a. To do.

  When the honeycomb core 2 and the face plate 3b are fixed to each other on the other side of the honeycomb core 2 to which the face plate 3a is not fixed again by the steps in FIGS. 2A to 2F, the honeycomb plate 1 is manufactured. I can do it. When the face plates 3a and 3b are transparent, the honeycomb plate formed in this manner has a good appearance because the adhesive 6b does not hang down on the side surfaces of the honeycomb core 2. Therefore, when it is used for a partition board etc. as a building interior material, it looks good. As mentioned above, although embodiment of this invention was described, this invention is not limited to the said embodiment.

It is a whole perspective sectional view of the honeycomb panel concerning an embodiment. It is a perspective view which shows the process of the manufacturing method of the honeycomb panel which concerns on embodiment. FIG. 3 is a side view showing a state of separating the honeycomb core from the adhesive layer, which is a manufacturing process of the honeycomb panel according to the embodiment.
