Description

  The present invention relates to a composite decorative panel, in particular, a composite decorative panel provided with a honeycomb structure as a core material, and a method for attaching a decorative edge member in the composite decorative panel.

  Conventionally, as a composite decorative panel used for a door or a storage door in a house, for example, a honeycomb structure material is used as a core, a thin decorative plate is bonded to the front side, and a MDF (medium fiber board) is provided on the back side. A panel structure having a sandwich structure in which wood materials such as the above are bonded together is known (see Patent Document 1). According to this, by using the honeycomb structure material as the core material, it is possible to reduce the weight and prevent the warpage.

  In addition, as a honeycomb structure material, in addition to a paper honeycomb formed from paper, a material formed from a light metal such as aluminum or a synthetic resin such as plastic is generally known. In addition, as the structure of the honeycomb, for example, a structure in which a large number of hexagonal cells are arranged, or a structure in which corrugated portions formed in a corrugated shape along a longitudinal direction and flat plate-shaped flat portions are alternately stacked is configured. Things are known.

  On the other hand, the thing which stuck the makeup | decoration edge member to the mouth of woody materials, such as particle board via an adhesive agent is also known (refer patent document 2). According to this, the design can be improved not only on the front surface side and the back surface side of the wooden material but also on the mouth end surface, and for example, it can be used as a table top plate or a shelf plate.

  However, in the panel body having the honeycomb structure as the core as described above, even if it is attempted to bond the decorative edge member to the end face, sufficient adhesion strength cannot be obtained, and for example, it is large relative to the decorative edge member. When a tensile force is applied, there is a concern that the decorative edge member peels off. More specifically, since the honeycomb structure material is formed in a honeycomb shape by combining thin plate members so that many voids are formed inside, the end face when the panel body is cut to a desired size (Kiguchi surface) was an uneven surface in which many depressions were formed at predetermined intervals, and a sufficient adhesion area could not be secured. In other words, the decorative edge member and the honeycomb structure material are in contact with each other only at the end face (that is, the linear portion) of the thin plate member constituting the honeycomb structure material, so that sufficient adhesive strength can be obtained from the lack of the bonding area. I could not.

  Therefore, in view of the above situation, the present invention can provide a composite decorative panel capable of obtaining sufficient adhesion strength to the honeycomb structure material and preventing peeling of the decorative edge member, and a decorative edge in the composite decorative panel. An object is to provide a method for attaching a member.

The composite decorative panel according to the present invention includes a “honeycomb structure material,
Using the honeycomb structure material as a core material, a surface material bonded to the surface side of the honeycomb structure material;
A back surface material bonded to the back surface side of the honeycomb structure material;
A decorative rim member attached to a front end of a sandwich-structured panel body composed of the surface material, the honeycomb structure material, and the back surface material;
The end face of the honeycomb structure material is formed so as to protrude outward from the mouth end surface of the panel body, and then provided with a plurality of bent protruding pieces bent along the end face,
The decorative edge member is affixed to the end face of the panel body including the plurality of bent protruding pieces via an adhesive ”.

  Here, as the “honeycomb structure material”, a paper honeycomb made of paper or a metal honeycomb made of a light metal such as aluminum may be used. Further, the configuration of the honeycomb is not particularly limited, and examples thereof include a configuration in which wavy portions and flat portions are alternately stacked, and a configuration in which a large number of hexagonal cells are arranged. .

  Moreover, although the material of "surface material" and "back surface material" is not specifically limited, a melamine decorative board or MDF (medium quality fiber board) can be illustrated. The “surface material” and the “back surface material” may each be composed of a single member, but may be composed of a plurality of thin plate members bonded together. For example, the surface material may be composed of a melamine decorative board and paper tube base paper, and may be bonded so that the melamine decorative board is on the surface side (outside). Further, the material of the “decorative edge member” is not particularly limited, and may be a resin member such as an ABS resin or wood.

  In addition, the “folded protruding piece” may be bent as a shape, and may be configured by, for example, determining a bending direction in advance and applying a force in that direction, and pressing the protruding piece inward. You may comprise by crushing.

  According to the composite decorative panel of the present invention, the panel body has a sandwich structure, the honeycomb structure material is used as a core material, the surface material is bonded to the front surface side, and the back material is bonded to the back surface side. In particular, a plurality of bent protruding pieces are formed on the end face of the honeycomb structure material, and a decorative edge member is attached to the end face of the panel body including these bent protruding pieces via an adhesive. Yes. Here, the bent protruding piece is formed by bending the protruding piece protruding outward from the end face of the panel body along the end face, and according to this, the end face of the honeycomb structure material In this state, the gap is closed by the bent protruding piece. That is, the area that contacts the decorative edge member increases, and as a result, the adhesion area can be greatly increased.

In addition, the method of attaching the decorative edge member in the composite decorative panel of the present invention is "honeycomb structure,
Using the honeycomb structure material as a core material, a surface material bonded to the surface side of the honeycomb structure material;
With a method for attaching a decorative edge member in a composite decorative panel, in which a decorative edge member is attached to the mouth end surface of the panel body with respect to a panel body having a sandwich structure composed of a reverse surface material bonded to the reverse surface side of the honeycomb structure material. There,
A projecting piece forming step of forming a plurality of projecting pieces by projecting the end face of the honeycomb structure material relatively outward from the end surface of the panel body by cutting out the end surfaces of the surface material and the back material. When,
A protruding piece bending step of forming a plurality of bent protruding pieces located on substantially the same plane as the front end of the panel body by bending the protruding pieces protruding outward along the front end of the panel body; ,
And a sticking step in which the decorative edge member is pressure-bonded to the front end of the panel body including the plurality of bent protruding pieces via an adhesive ”.

  According to the method for attaching a decorative edge member in the composite decorative panel of the present invention, when the decorative edge member is attached to the end of the panel body, at least the protruding piece forming step, the protruding piece bending step, and the attaching step are sequentially performed. Done. First, in the protruding piece forming step, the end surfaces of the front surface material and the back surface material are notched so that the end surface of the honeycomb structure material protrudes relatively outward from the end surface of the panel body to form a plurality of protruding pieces. When the end surfaces of the front surface material and the back surface material are cut out, part of the honeycomb structure material adjacent to the front surface material and the back surface material may be cut out together. That is, the protruding piece may be formed on the entire end face of the honeycomb structure material, but may be formed only on the central portion excluding both sides. Moreover, although the notch method is not specifically limited, For example, the method of moving a rotary blade relatively along the end face can be illustrated.

  Next, in the protruding piece bending step, the plurality of protruding pieces protruding outward are bent along the front end of the panel body (that is, the end surfaces of the notched surface material and back surface material). Thereby, the some bending protrusion piece located on the substantially the same plane as the end face is formed.

  In the subsequent sticking step, the decorative edge member is adhered to the front end of the panel body including the plurality of bent protruding pieces. That is, an adhesive is applied to one or both of the inner surface of the decorative edge member and the top surface of the panel body, and the decorative edge member and the front end surface of the panel body having a plurality of bent protruding pieces are butt-bonded to each other. . By pasting the decorative edge member through such a process, it becomes possible to manufacture a composite decorative panel in which the adhesive strength of the decorative edge member is significantly increased.

  Thus, according to the present invention, by forming a plurality of bent protruding pieces on the end face of the honeycomb structure material, the adhesion area to the decorative edge member is greatly increased, and the adhesion between the panel body and the decorative edge member is achieved. The strength can be increased, and as a result, peeling of the decorative edge member can be reliably prevented.

It is a disassembled perspective view which shows the structure of the composite decorative panel of this embodiment. It is an expansion perspective view which shows the structure of the principal part in a panel body, (a) shows the conventional structure, (b) has shown the structure of this embodiment. It is a conceptual diagram which shows the flow of the process regarding the manufacturing process of a composite decorative panel. It is explanatory drawing which shows typically the sticking method etc. of a makeup | decoration edge member.

  Hereinafter, a composite decorative panel according to an embodiment of the present invention will be described with reference to FIGS. 1 and 2. The composite decorative panel 1 of the present embodiment can be used as a table top plate, a shelf board, a TV stand, a storage door, a partition wall or a door of a house, and the like as shown in FIG. A panel member 5 having a sandwich structure is composed of a surface material 3 affixed to the front surface side 2 and a back material 4 affixed to the back surface side. In addition, a decorative edge member 7 is attached to the whole end surface 5a of the panel body 5 over the entire circumference, and the design is improved not only on the front and rear surfaces of the panel body 5, but also on the front end surface 5a. . Here, the paper honeycomb 2 corresponds to the honeycomb structure material of the present invention.

  Each member will be described in detail. The paper honeycomb 2 includes a corrugated portion 10 formed in a corrugated shape along the longitudinal direction, and a flat plate portion 11 that is bonded to the top of the corrugated portion 10 and has the same width and length as the corrugated portion 10. The single-sided corrugated board 9 is provided as one layer. A plurality of single-sided cardboards 9 are juxtaposed in a horizontal direction perpendicular to the flat portion 11 and bonded together to form an integrated plate-like honeycomb structure. Since such a paper honeycomb 2 uses paper as a raw material and has many voids inside, it can be reduced in weight compared to a woody material such as particle board and has a honeycomb structure, so that warp and twist Can be prevented. In addition, since the paper honeycomb 2 is configured by arranging a plurality of single-sided cardboards 9 in the horizontal direction, the first end face 2a parallel to the flat part 11 of the single-sided cardboard 9 and a second end part perpendicular to the flat part 11 are provided. The end face shape is different from that of the surface 2b. That is, in forming the panel body 5 of a predetermined size, in the first end face 2a that appears when the corrugated portion 10 is cut in parallel with the flat portion 11, the cut surface of the corrugated portion 10 is constant through the gap. It becomes the form by which the flat part 11 is arrange | positioned at the back | inner side of the space | gap while being arrange | positioned at intervals. On the other hand, in the second end face 2b that appears when cut perpendicularly to the flat portion 11 (that is, along the stacking direction of the single-sided cardboard 9), the cut surfaces of the flat portion 11 are arranged at regular intervals through a gap. In addition, the wavy portion 10 is disposed in the gap. Note that, as a characteristic configuration, a plurality of bent protruding pieces 12 are formed on the first end face 2a and the second end face 2b of the paper honeycomb 2 of this example, which will be described later.

  The surface material 3 attached to the surface side of the paper honeycomb 2 with an adhesive is composed of a melamine decorative board 16 and a paper tube base paper 17. The melamine decorative board 16 is generally used as a finished surface of furniture, doors, etc., and is hard to be damaged because of its high surface hardness, and is excellent in water resistance and easy to clean. Furthermore, since there are various types such as color and wood grain, it is possible to finish the table top with excellent decorativeness. On the other hand, the paper tube base paper 17 is recycled paper obtained by recycling used paper, and is used for manufacturing a core rod for winding paper, foil, fabric, and the like. Although the thickness is not particularly limited, a 1 mm paper tube base paper 17 is used in this example.

  The back surface material 4 attached to the back surface side of the paper honeycomb 2 via an adhesive is made of MDF (medium fiber board). MDF is made by loosening wood into a fiber and blending an adhesive into a board shape. The MDF obtains a stable strength and is less prone to warping and twisting and is easy to process.

  The decorative edge member 7 is affixed to the entire wood face 5a of the panel body 5 including the paper honeycomb 2, the surface material 3, and the back material 4, and has a strip shape formed of ABS resin. It is also possible to form the synthetic resin other than ABS resin or wood. The decorative edge member 7 is adhered to the wood surface 5a of the panel body 5 via an adhesive. Specific examples of the adhesive include an ethylene-vinyl acetate resin hot melt adhesive mainly composed of a resin obtained by copolymerizing ethylene vinyl alcohol (EVA) and vinyl acetate, and an amorphous polypropylene resin (APP). Mention may be made of a polyolefin resin hot-melt adhesive having a main component.

  By the way, a general paper honeycomb is formed in a honeycomb shape by combining thin plate-like members so that many voids are formed inside, so that an end surface when the panel body is cut to a desired size ( As shown in FIG. 2 (a), the end surface of the thin-plate-shaped member (ie, the linear portion) is in contact with the end face (ie, the end face), and the bonding area is extremely small.

  On the other hand, in the paper honeycomb 2 of this example, as shown in FIG. 2B, a plurality of bent protruding pieces 12 are integrally formed on the first and second end surfaces 2a and 2b. The decorative edge member 7 is attached to the end face 5a including these bent protruding pieces 12 via an adhesive. The bent projecting piece 12 is formed by projecting the projecting piece 12a (see FIG. 4B) projecting outward from the wood end surface 5a of the panel body 5 along the wood end surfaces 3a and 4a of the surface material 3 and the back surface material 4. It is formed by bending. According to this, the space | gap in the end surface of the paper honeycomb 2 will be in the state obstruct | occluded by the some bending protrusion piece 12, and the area contact | abutted to the decorative edge member 7, ie, the adhesion area with respect to the decorative edge member 7, is increased significantly. Is possible. In this example, the inner surface of the decorative edge member 7 is also bonded to the front end surfaces 3 a and 4 a of the front surface material 3 and the rear surface material 4 by the adhesive 14 applied to the inner surface side of the decorative edge member 7. In other words, the adhesive strength of the decorative edge member 7 is greatly increased by using substantially the entire wood surface 5a of the panel body 5 as the surface to be bonded.

  Next, a method for manufacturing the composite decorative panel 1, particularly a method for attaching the decorative edge member 7 in the composite decorative panel 1, will be described with reference to FIGS. 3 and 4. As shown in FIG. 3, the production line 19 has four steps of attaching the decorative edge member 7 to the panel body 5 conveyed by a conveyor (not shown), that is, a protruding piece forming step 20 and a protruding piece folding. The bending process 21, the adhesive application process 22, and the crimping process 23, and thereafter, four processes for processing the decorative edge member 7, that is, an end cut process 24, a trimming process 25, a scraper process 26, and a round trimming process 27 are performed. They are provided in order from the right side to the left side of the page.

  In addition, since the panel body 5 is rectangular in plan view, when the decorative edge member 7 is attached over the entire circumference, the decorative edge member 7 needs to be attached to each of the four end surfaces 5a. A series of processes in the manufacturing line 19 is repeated four times. Further, the last round trimming step 27 is performed only once after the decorative edge member 7 is attached to all the end surfaces 5a.

  Each step will be described. In the protruding piece forming step 20, as shown in FIGS. 4A and 4B, among the end surfaces 5 a of the panel body 5, the end surfaces of the surface material 3 and the back surface material 4 and the first end adjacent to the end surfaces. The rotary blade 30 is brought into contact with both end sides of the surface 2a and the second end surface 2b, and the rotary blade 30 is relatively moved in the horizontal direction (the front side in FIG. 3), whereby the surface material 3 And the end surface of the back surface material 4 is notched, and the some protrusion piece 12a which protrudes outward relatively from the wood end surface 5a of the panel body 5 is formed. In this example, the end surfaces of the surface material 3 and the back material 4 are cut so that the protruding length of the protruding piece 12a is about 5 mm.

  In the protruding piece bending step 21, as shown in FIGS. 4B and 4C, the plurality of protruding pieces 12 a protruding outward are formed from the front end 5 a of the panel body 5 (that is, the notched surface material 3 and the back surface). Bend along the end face of the material 4. Thereby, the some bending protrusion piece 12 located on the substantially same plane as the end face 5a is formed (refer FIG.2 (b)). Further, in the protruding piece bending step 21, after bending the protruding piece 12a, pressure is applied by a press or the like to crush the end face, and according to this, the end face of the paper honeycomb 2 is finished to a flat surface. It is done.

  In the adhesive application step 22, as shown in FIG. 4D, the application roller 32 is rolled while supplying the adhesive 14 stored in a tank (not shown) to the inner surface of the decorative edge member 7. The adhesive 14 is applied to the entire inner surface of the decorative edge member 7 with a uniform thickness. The decorative edge member 7 is continuously fed out by a feeding device (not shown). In the adhesive application step 22, the decorative edge member 7 having a required length according to the dimensions of the panel body 5 is used. Then, the adhesive 14 is applied. In FIG. 4D, for the sake of convenience, the rotation axis of the application roller 32 is shown as rolling in the horizontal direction, but it is rolled up in the horizontal direction (along the line) with the rotation axis as the vertical direction. You may do it. Moreover, you may make it apply | coat the adhesive agent 14 to the wooden surface 5a side of the panel body 5. FIG.

  In the crimping step 23, as shown in FIG. 4 (e), the decorative edge member 7 having the inner surface coated with the adhesive 14 and the front end 5a of the panel body 5 on which the bent protruding pieces 12 are formed are brought into contact with each other. Thereafter, the pressing roller 33 is rolled on the outer surface of the decorative edge member 7, thereby pressing the decorative edge member 7 and the panel body 5. At this time, the width (length in the vertical direction) of the decorative edge member 7 is larger than the thickness of the panel body 5, and the sticking position of the decorative edge member 7 to the wooden face 5 a of the panel body 5 is in the vertical direction. Even if it deviates, it is possible to reliably cover the front end 5a of the panel body 5. In FIG. 4 (e), for the sake of convenience, the rotation axis of the pressing roller 33 is shown as being horizontal and rolling up and down. However, the rotation axis is vertical and rolling in the horizontal direction (along the line). You may do it. Here, a combination of the adhesive application step 22 and the pressure bonding step 23 corresponds to the sticking step of the present invention.

  In addition, since the end cut process 24-round trimming process 27 performed after completion | finish of the crimping | compression-bonding process 23 is a well-known process conventionally implemented, detailed description is abbreviate | omitted here, but in the end cut process 24, The decorative edge member 7 continuously fed out by the feeding device is cut after sticking. Further, in the trimming step 25, as shown in FIG. 4 (f), an excessive portion of the decorative edge member 7 that protrudes from the upper surface or the lower surface of the panel body 5 is cut out with a blade (not shown). As shown in FIG. 4G, the scraper process 26 chamfers the edge 34 by bringing a blade (not shown) into sliding contact with the upper and lower edges 34 of the decorative edge member 7 in the longitudinal direction. Moreover, in the round trimming process 27, as shown in FIG.4 (h), a cutting tool (not shown) is slid in the up-down direction with respect to the butting | matching part 35 of the end surfaces of the decorative edge member 7, and the part 35 of FIG. Perform chamfering.

  Thus, according to the composite decorative panel 1 of the present embodiment, the plurality of bent projecting pieces 12 are formed on the first and second end surfaces 2a and 2b of the paper honeycomb 2, and these bent portions are formed. Since the decorative edge member 7 is stuck to the wood surface 5a of the panel body 5 including the protruding piece 12 via the adhesive 14, the bonding area to the decorative edge member 7 is greatly increased, and the panel body 5 and the decorative edge The adhesive strength with the member 7 can be increased, and as a result, peeling of the decorative edge member 7 can be reliably prevented.

  The present invention has been described with reference to preferred embodiments. However, the present invention is not limited to these embodiments, and various modifications can be made without departing from the spirit of the present invention as described below. And design changes are possible.

  That is, in the said embodiment, although the thing using the melamine decorative board 16 and the paper tube base paper 17 was shown as the surface material 3, you may make it use wooden materials, such as MDF like the back surface material 4. FIG.

  In the above embodiment, the surface material 3 and the back material 4 are directly bonded to the paper honeycomb 2. However, a paper member such as cardboard is pasted on the front surface and the back surface of the paper honeycomb 2 in advance. You may make it adhere | attach the surface material 3 and the back surface material 4 with respect to the paper honeycomb board formed.
