Description

  The present invention relates to a product obtained by attaching a surface material to a plate-like base material used for building materials and the like, and a manufacturing technique thereof.

  Conventionally, plate-like products have been widely used for building materials, and as one of the products, sheets are pasted as surface materials on the top and both sides of the plate-like base material, and the remaining surface is painted or A sheet wrapping product in which a sheet is attached in a separate process is known. Conventionally, in order to manufacture this type of sheet wrapping product, a plate-shaped base material is conveyed in the longitudinal direction by an apparatus called a wrapping machine, and the base material has a width wider than the base material width. The sheet was attached by applying an adhesive to the sheet, and both side edges of the sheet were gradually wound around and pasted on the side surface of the substrate using rollers (see Japanese Patent No. 2736232). However, in conventional wrapping machines, there is no probability of attaching a sheet to the front and back sides of a running base material, so the sheet cannot be attached to the front and back sides of the base material. In the process, a sheet was attached to the front and back sides of the substrate or painted. However, this manufacturing method is inferior in productivity, and requires labor for another device, so labor costs are incurred.

Japanese Patent No. 2736232

  The present invention has been made in view of such problems, and is a sheet having a configuration in which a top surface of a plate-like base material and at least each of the four side surfaces adjacent to the top surface are covered with a single sheet. It is an object to provide a wrapping product.

  In addition, the present invention produces a sheet wrapping product having a configuration in which at least a region adjacent to the top surface of each of the plate-like base material and the four side surfaces of the base material is covered with a single sheet. Another object of the present invention is to provide a manufacturing method and apparatus that can be manufactured with good performance.

  In order to solve the above-mentioned problem, the sheet wrapping product of the present invention is a sheet of base material and one sheet that is affixed to at least a region adjacent to the top surface of each of the top surface and the four side surfaces of the base material. In addition, the top surface of the base material is in a planar state before the sheet is attached to the top surface of the base material, but is attached to the top surface of the base material. And a pair of first side surface sticking pieces for being attached to side surfaces along a pair of parallel first sides of the top surface, The first side surface includes a pair of second side surface adhesive pieces that are connected to the top surface pasting portion and are attached to side surfaces along a pair of second sides perpendicular to the first side of the top surface. The sticking piece and the second side sticking piece are formed by notches formed on the sheet so that the corners of the top surface are apexes. Furthermore, one of the first side surface sticking piece and the second side surface sticking piece extends outward from the side surface of the base material to which the first side surface sticking piece and the second side surface sticking piece are attached, and can be attached to the adjacent side surface. The other of the first side surface adhesive piece and the second side surface adhesive piece is close to the protrusion portion attached to the side surface when it is attached to the side surface of the substrate. Both ends are recessed so as not to overlap, and the first side surface adhesive piece and the second side surface adhesive piece are attached to the four side surfaces of the base material so as not to overlap.

  In order to solve the above-described problems, the sheet wrapping product manufacturing method and apparatus of the present invention attach a continuous sheet having a width wider than the width of the top surface to the top surface of the substrate conveyed at regular intervals. By separating the sheet at an intermediate position between the material and the base material, an intermediate product is created by attaching the sheet to the top surface of the base material so that the sheet extends outside the four sides of the top surface. Side surfaces along the pair of first sides of the top surface in a region outside the top surface of the sheet by forming notches with the corners of the base material top surface as apexes in the four corner portions. Forming a pair of first side surface sticking pieces to be attached to the top surface and a pair of second side surface sticking pieces to be attached to the side surfaces along the pair of second sides perpendicular to the first side of the top surface; Place it on one end of the first side piece and the second side piece A projecting portion extending outward from the side surface of the base material to be attached is formed, and the base material is transported in parallel to a pair of side surface sticking pieces on the side forming the projecting portion, and both sides with respect to the traveling direction. The pair of side surface adhesive pieces located on the side of the base material are wound around and attached to the side surface of the base material, and then the base material is stopped. Affix to the side adjacent to the side to which the piece is affixed, and then attach the base material to the side surface in a direction perpendicular to the direction that the pair of side surface adhering pieces are wrapped and attached to the side surface of the base material first. While the side sticking piece having the attached protruding portion is conveyed as the back side, the protrusions at both ends of the side sticking piece located on the front side with respect to the traveling direction and the pair of side sticking pieces located on both sides are wound around the side of the substrate. A configuration to paste Than is.

  Here, in the manufacturing method and apparatus described above, the base material is stopped, and in this state, the protrusions at one end of the pair of side surface adhesive pieces are attached to the side surface adjacent to the side surface to which the side surface adhesive piece is attached. Instead of attaching, it is good also as a structure which sticks the protrusion part of both the both ends of a pair of side surface sticking piece to the side surface adjacent to the side surface which stuck the side surface sticking piece.

  The sheet wrapping product of the present invention covers the entire area of the base material top surface and at least the top surface of each of the four side surfaces with a single sheet, and also forms a ridge line between the adjacent side surfaces on the sheet. Since it is covered with a protruding part, it looks very good, looks like a real board, and water absorption from the side is suppressed, so it becomes a high-quality, high-functional product. In addition, since the protrusions attached to the side of the same substrate and the side application pieces do not overlap, there is no level difference due to the application of the sheet, and this sheet wrapping product is installed side by side to form the floor or wall surface. When doing, it has the effect that both can be made to contact | adhere well and the floor surface and wall surface which look good can be formed.

  According to the manufacturing method and apparatus of the present invention, a sheet is attached to the top surface of the base material, cutouts are formed in the four corner portions of the sheet, and the sheets are separated from each other along the four sides of the top surface. A pair of first side surface adhesive pieces and a pair of second side surface adhesive pieces are formed, and a pair of side surface adhesive pieces on the side having protrusions are attached to the side surfaces of the base material, and then the protrusion portions are attached to the adjacent base material side surfaces. Then, the operation of sticking the remaining side surface sticking piece on the side surface of the substrate can be performed in-line. For this reason, by using the manufacturing method and apparatus of the present invention, the above-described sheet wrapping product of the present invention can be manufactured in-line, and the production efficiency can be increased and the labor cost can be reduced.

  Hereinafter, preferred embodiments of the present invention will be described. FIG. 1 shows a sheet wrapping product according to an embodiment of the present invention. (A) is a schematic perspective view thereof, (b) is a sheet wrapping product, and a sheet is attached to the top surface of a substrate. However, FIG. 4C is a schematic perspective view showing a planar state before being attached to the four side surfaces of the substrate, and FIG. The sheet wrapping product indicated as a whole by reference numeral 1 is composed of a plate-like base material 2 and a single sheet 3 attached to the top surface and four side surfaces of the base material 2. Examples of the base material 2 include wood, plywood, resin board, and particle board. The sheet 3 acts as a surface material for decorating or protecting the substrate, and examples thereof include a veneer, a print paper, various plastic films, and a laminated sheet.

  The base material 2 includes a top surface 2a, a pair of side surfaces 2b along a pair of parallel first sides 2ab of the top surface 2a, and a pair of second sides 2ac perpendicular to the first side 2ab of the top surface 2a. A pair of side surfaces 2c is provided. As shown in FIG. 1 (b), the sheet 3 is bonded to the top surface 2a of the substrate 2 but in a planar state before being bonded to the four side surfaces 2b and 2c. The top surface sticking part 3a affixed to the top surface of the top surface and a pair of first side surface sticking pieces that are connected to the top surface sticking part 3a and are attached to the side surface 2b along the pair of first sides 2ab of the top surface 3b and a pair of second side surface sticking pieces 3c that are connected to the top surface attaching portion 3a and are attached to the side surface 2c along the pair of second sides 2ac of the top surface. The first sticking piece 3b and the second sticking piece 3c are separated by a notch 4 formed in the sheet 3 so as to have the top corner 2ad positioned between them as a vertex, and interfere with each other. Without being attached to the side surfaces 2b and 2c. Further, the pair of first side surface sticking pieces 3b formed on the outer side of the first side 2ab of the top surface has a triangle extending beyond both ends of the side surface 2b to which the first side surface sticking piece 3b is attached at both ends thereof. A protruding portion 3bc having a shape is provided, and the protruding portion 3bc can be attached to the side surface 2c along the adjacent second side 2ac. On the other hand, both ends of the pair of second side surface adhesive pieces 3c are attached to the side surface 2c when the second side surface adhesive piece 3c is attached to the side surface 2c along the second side 2ac except for the region in contact with the top surface. It is in a shape that is recessed from both ends of the second side 2ac and the side surface 2c so as to be close to but not overlap with the attached protruding portion 3bc. The 1st side surface sticking piece 3b and the 2nd side surface sticking piece 3c are set to the magnitude | size which can cover the substantially whole region of the base material side surfaces 2b and 2c.

  As shown in FIG. 1A, the sheet 3 having this shape is formed by bending the first side surface sticking piece 3b along the first side 2ab of the top surface and sticking the first side surface sticking piece 3b to the base material side surface 2b. Is bent along the ridge line between the substrate side surfaces 2b and 2c, and is affixed to the substrate side surface 2c. The second side surface adhesive piece 3c is bent along the second side 2ac of the top surface and is affixed to the substrate side surface 2c. Thus, the base material 2 is wrapped. The sheet wrapping product 1 having this structure covers not only the top surface 2a of the base material 2 but also almost the entire area of the four side surfaces 2b and 2c with one sheet 3, and the ridgeline between the side surfaces 2b and 2c is also a sheet. Since it is covered with 3, it looks very good and also suppresses water absorption from the side, making it a high-quality, high-function product. Furthermore, although the protrusion part 3bc and the 2nd side surface sticking piece 3c which are affixed on the base material side surface 2c are adjoining, since there is no overlap, the level | step difference has not arisen. For this reason, when this sheet wrapping product 1 is arranged side by side to form a floor surface or wall surface, the side surfaces can be attached in good contact with each other, and there is an advantage that a very good looking floor surface or wall surface can be formed. .

  FIG. 2 shows a sheet wrapping product 1A according to another embodiment of the present invention. This sheet wrapping product 1A has triangular protrusions 3cb extending beyond both ends of the base material side surface 2c at both ends of the second side surface sticking piece 3c formed outside the second side 2ac of the base material top surface. The both ends of the other first side surface sticking piece 3b are formed so as to be retracted corresponding to the protruding portion 3cb, and the protruding portion 3cb is attached to the side surface 2b. Advantages similar to those of the embodiment shown in FIG. 1 can be obtained by the sheet wrapping product 1A having this configuration.

  In the embodiment shown in FIGS. 1 and 2, the protrusions 3bc and 3cb are triangular, but the shape of the protrusion is not limited to this, and can be changed as appropriate. For example, as shown in FIG. The projecting portion 3bc may be shaped like a triangular tip, and the end shape of the second side surface sticking piece 3c may be shaped to match the shape of the projecting portion 3bc. Also by this, a sheet | seat can be affixed on the substantially whole surface of the side surface 2c, without producing the overlapping part of a sheet | seat on the base material side surface 2c.

  Furthermore, in above-mentioned embodiment, it is set as the structure which covers the substantially whole area of 4 side surface 2b, 2c of the base material 2 with the 1st side surface adhesive piece 3b and the 2nd side surface adhesive piece 3c, However, 4 side surface 2b, 2c is thickness. It is not always necessary to cover the entire area in the direction, and it is sufficient to cover at least the area adjacent to the top surface 2a. FIG. 4 shows an embodiment in that case. In this embodiment, the area adjacent to the top surface of the four side surfaces 2b and 2c is covered with the first side surface adhesive piece 3b and the second side surface adhesive piece 3c. It is said. In general, since a large number of sheet wrapping products 1 are used side by side, only the area adjacent to the top surface of the four side surfaces 2b and 2c can be seen from the surface side. Therefore, if only that portion is covered with the sheet 1, it looks good. ,No problem. Moreover, the groove | channel and convex strip for a fitting may be formed in the side surface of the base material 2, In that case, it is in the area | region from the top surface to a groove | channel or a convex strip of 4 side surfaces 2b and 2c. What is necessary is just to set it as the structure which affixes the 1st side surface sticking piece 3b and the 2nd side surface sticking piece 3c.

  Furthermore, the dimension of the base material thickness direction of the 1st side surface sticking piece 3b and the 2nd side surface sticking piece 3c affixed on the 4 side surfaces 2b and 2c of the base material 2 does not necessarily need to be the same, for example, in FIG. As shown, the pasting area in the side face thickness direction of the first side sticking piece 3b may be reduced and the pasting area in the side face thickness direction of the second side sticking piece 3c may be increased.

  Next, a manufacturing method and apparatus for the sheet wrapping product having the above configuration will be described. 6A is a schematic plan view showing a sheet wrapping product manufacturing apparatus that manufactures the sheet wrapping product 1 shown in FIG. 1, and FIG. 6B is a notch 4 formed on the sheet 3 attached to the top surface of the substrate 2.
