BACKGROUND OF THE INVENTION
The present invention relates to an embossing technique.
[0002]
[Prior art]
The package, which is a paper container, is not only decorated by printing on base paper such as paperboard or cardboard, but also, for example, information on products packaged in the package by imprinting Braille Consumers are attracted by making it available to people and embossing animal designs.
[0003]
[Problems to be solved by the invention]
By the way, it is not efficient to perform braille or other embossing on individual packages, because the package is not productive or economical.
[0004]
Therefore, conventionally, an embossing apparatus that performs braille or other embossing has been proposed (for example, see Patent Document 1).
[0005]
[Patent Document 1]
JP 59-136777 A (FIG. 1, FIG. 2, FIG. 3)
[0006]
The embossing device not only embosses a base paper such as paperboard but also punches a paper (so-called blank) before assembling the package from the base paper.
In the embossing apparatus, a plate material called a die used for embossing or blank punching is used.
The punching die has a cutting blade for cutting a blank from a base paper and a ruled line blade for forming a ruled line (folding line) for making the blank three-dimensional. The punching die moves in a state of being opposed to the base paper supplied to the embossing device, punches a blank from the base paper with the cutting blade, and puts a ruled line in the blank with the ruled blade.
[0007]
On the other hand, in order to form the emboss, a desired portion of the blank is pressed with a metal convex mold as well as a metal concave mold.
[0008]
By the way, in the case of small embossing such as Braille, the size may be uneven or distorted depending on how the force acting on the blank is applied.
[0009]
The present invention has been made in view of the above circumstances, and a problem to be solved is to efficiently perform an embossing process more sophisticated than before.
[0010]
[Means for Solving the Problems]
In order to solve the above problems, the present invention has a concave mold and a convex mold for emboss formation on a base paper, and the base paper is fitted by fitting the concave mold and the convex mold in a state where the base paper is arranged between both molds. In the emboss forming apparatus for forming an emboss on the second face, a first face plate having one of the concave shape or the convex shape, and a second face having the other of the concave shape or the convex shape arranged opposite to the first face plate. A face plate and an elastic body that is attached to either the first face plate or the second face plate and supports the concave shape or the convex shape provided on the face plate to be attached are provided.
[0011]
In the present invention, one of these concave and convex molds is supported by an elastic body, so if pressing is performed with the base paper sandwiched between the concave mold and the convex mold, the pressing force at that time also acts on the elastic body, and thus elastic An elastic force is generated in the body, and the elastic force acts as a reaction force on a concave or convex shape that is not supported by the elastic body. The reaction force gradually presses the base paper as compared with the case where there is no elastic body, so that the amount of biting into the concave and convex base paper does not become abrupt. Therefore, since the plastic deformation of the base paper becomes gentle, the emboss can be formed clearly and clearly. Therefore, even fine embossing such as Braille can be finely formed.
[0012]
You may make it have two or more sets of the said concave type, convex type, and the said elastic body attached to the said 1st face plate and the said 2nd face plate.
Exquisite embossing can be efficiently performed by providing a plurality of emboss forming means.
[0013]
Since the application of pressure can be made uniform by the elastic body, it can be applied even when a plurality of packages are formed.
[0014]
Moreover, this invention is also an embossing method, and this method is the said 1st face plate before attaching any said type | mold to the 1st face plate to which one of the concave type or convex type | mold for emboss formation to a base paper is attached. An elastic body is fixed to the elastic body, the concave or convex shape is supported by the elastic body, the other of the concave or convex shape is attached to a second face plate, and the first face plate and the second face plate are interposed between them. The base paper is introduced, and one of the first and second face plates is brought close to the other face plate, and the base paper is pressed with the concave and convex shapes to emboss the base paper.

DETAILED DESCRIPTION OF THE INVENTION
(First embodiment)
[0016]
Hereinafter, an embodiment of the present invention (hereinafter referred to as an embodiment) will be described with reference to FIGS. In the drawing, only the main part relating to the embossing apparatus of the present invention is shown.
[0017]
First, FIG. 1 is a cross-sectional view of the main part of the embossing apparatus.
[0018]
In this apparatus, a die 1 as a first face plate is mounted, and a metal plate 2 as a second face plate is attached in parallel with the die 1 in the vertical direction of FIG. A base paper 3 is introduced between the die 1 and the metal plate 2, and the base paper 3 is embossed by pressing the base paper 3 with the die 1 and the metal plate 2. At the same time, a desired package blank (hereinafter, blank) 3 ′ (see FIG. 4) is punched from the base paper 3.
[0019]
2 and 3 are a plan view and a perspective view of the die 1.
[0020]
The cutting die 1 is provided by, for example, planting a cutting blade 5 and a ruled line blade 7 on a wooden substrate 4.
[0021]
The cutting blade 5 is disposed on the substrate 4 in an endlessly continuous state when seen in a plane, and the blank 3 ′ is cut from the base paper 3 by the cutting blade 5 being pierced into the base paper 3.
[0022]
The ruled line blade 7 is inside the cutting blade 5 and the ruled line blade 7 presses the base paper 3 to form a ruled line 12 as shown in FIG. 4 on the blank 3 ′.
[0023]
On the upper surface 4 a of the substrate 4, a rubber body 13 is formed along the cutting edge 5 for separating the base paper 3 from the cutting edge 5 and the die 1 after punching out the blank 3 ′.
[0024]
The rubber body 13 is compressed between the metal plate 2 and the punching die 1 when the blank 3 ′ is punched. At this time, an elastic repellency is generated, and the cutting blade 5 biting into the base paper 3 by the elastic repellency is It becomes easy to separate from the base paper 3.
[0025]
Further, a cork 21 having a hardness of 20 to 80 degrees that functions as an elastic body is bonded to the upper surface 4 a of the substrate 4, and a metal female braille forming plate 23 (concave) is placed on the upper surface 21 a of the cork 21. Supported by the state. The female braille forming plate 23 has a recess 23b that opens on the upper surface 23a. When the base paper 3 is deformed in accordance with the shape of the concave portion 23b, it becomes one of six points constituting Braille. In addition, if it is in the said range, it will not be limited to a cork, A rubber | gum, resin, a cell poly (polyolefin type), and another elastic body may be sufficient. The female braille forming plate 23 supported by the cork 21 is adjusted in height so as not to protrude from the cutting blade 5 and the ruled line blade 7. Note that a screwing means such as a screw may be used so that the female braille forming plate 23 can be freely attached to the substrate 4 of the die 1.
[0026]
A male braille forming plate 26 (convex type) is fixed to the metal plate 2 by a double-sided adhesive tape 27 so as to face the female braille forming plate 23. The male Braille forming plate 26 has a convex portion 26b that protrudes downward in FIG. 1 from its upper surface (surface on the female Braille forming plate side) 26a. With the base paper 3 positioned between the male braille forming plate 26 and the female braille forming plate 23, the die 1 is brought close to the metal plate 2 and the base paper 3 is moved to the male braille forming plate 26 and the female braille. Braille is formed on the base paper 3 by pressing with the forming plate 23.
[0027]
Further, the metal plate 2 is provided with a ruled crack prevention tool 29 corresponding to the ruled line blade 7.
[0028]
The attachment position of the female braille forming plate 23 may be anywhere as long as it is surrounded by the cutting blade 5, but it is preferably attached to the position that becomes the upper lid of the package when braille is imprinted on the base paper 3. This is because a blind person often touches the upper surface of a product (paper box) displayed at a store.
[0029]
Next, with reference to FIG. 1 and FIG. 5 to FIG. 8, steps until the embossed blank 3 ′ is extracted from the base paper 3 will be described.
[0030]
(1) First, the cork 21 is attached to the substrate 4 of the die 1 and then the female braille forming plate 23 is bonded to the upper surface 21a of the cork 21, thereby supporting the female braille forming plate 23 with the cork 21 (FIG. 5). reference).
[0031]
(2) A double-sided adhesive tape 27 is attached to the back surface of the male braille forming plate 26 and the male braille forming plate 26 is fitted to the female braille forming plate 23. Then, the male braille forming plate 26 is fastened to the female braille forming plate 23 with a known temporary fastening pin or temporary fastening tape (not shown) (see FIG. 5).
[0032]
(3) The die 1 is moved closer to the metal plate 2 when the blanking operation is performed before the blank 3 ′ is punched. When the male braille forming plate 26 in the temporarily fixed state is pressed against the metal plate 2, the male braille forming plate 26 is adhered to the metal plate 2 by the double-sided adhesive tape 27 (see FIG. 6).
[0033]
Thereafter, when the temporary fixing is released and the die 1 is moved away from the metal plate 2, the male braille forming plate 26 and the female braille forming plate 23 are disengaged, and the metal plate 2 has the male braille. The forming plate 26 is left (see FIG. 7).
[0034]
Moreover, the relative position of the die 1 and the metal plate 2 does not change. Therefore, if the die 1 is moved up and down with respect to the metal plate 2, when the male braille forming plate 26 and the female braille forming plate 23 are fitted, accurate fitting can be executed.
[0035]
(4) The base paper 3 is introduced between the female braille forming plate 23 and the male braille forming plate 26 supported by the cork 21, the die 1 is brought close to the metal plate 2, and the base paper 3 is eventually put into the male braille. By pressing with the forming plate 26 and the female braille forming plate 23, the emboss 25 is formed on the base paper 3, and the blank with the ruled lines 12 is punched out from the base paper 3 (see FIG. 1).
[0036]
Next, the function and effect of this apparatus will be described.
[0037]
Since the female braille forming plate 23 provided on the substrate 4 of the die 1 is supported by the cork 21, if the base paper 3 is sandwiched and pressed between the female braille forming plate 23 and the male braille forming plate 26, the pressing at that time The pressure also acts on the cork 21, so that an elastic force is generated in the cork 21. The elastic force of the cork 21 acts on the male braille forming plate 26 as a reaction force. Since this reaction force gradually presses the base paper 3 as compared with the case where the cork 21 does not exist, the amount of biting of the female braille forming plate 23 and the male braille forming plate 26 into the base paper 3 does not become rapid. Therefore, since the plastic deformation of the base paper 3 can be performed gently, the emboss 25 can be formed reliably and clearly. Therefore, even fine braille can be finely formed.
[0038]
Since the pressure applied by the cork 21 can be leveled, the present invention can be applied even when a plurality of packages are punched out. In this case, the substrate 4 and the metal plate 2 of the die 1 are enlarged and the female braille forming plate 23, the male braille forming plate 26 and the cork 21, the cutting blade 5, the ruled blade 7 and the rubber body placed on them. A plurality of 13 sets are prepared (see FIG. 9).
In this case, if there are a plurality of these members forming the emboss, the height can be corrected by the cork 21 even if the height of the concavo-convex shape is different. Therefore, when producing a plurality of the same blanks at a time, as well as producing a plurality of different types of blanks at a time, if the height dimensions of the concavo-convex shape of each blank are not extremely different, the cork 21 Since the difference in height of the concavo-convex mold can be absorbed by elasticity, a plurality of fine embossing processes can be simultaneously formed for each blank, which is efficient.
Therefore, productivity is improved and yield is increased.
[0039]
Further, in the present embodiment, the cork 21 that is an elastic body is attached to the die 1, but the cork 21 may be provided on the metal plate 2 side to support the male braille forming plate 26. In addition, although it has been described that the die 1 moves with respect to the metal plate 2, it is a matter of course that the metal plate 2 may move with respect to the die 1. Furthermore, in this embodiment, although the thing which adhere | attaches the male type braille forming plate 26 on the metal plate 2 using the double-sided adhesive tape 27 was illustrated, an adhesive agent can be utilized instead of the double-sided adhesive tape 27.
