JP6180129B2 - Album and method for manufacturing the album - Google Patents

Description

  The present invention relates to an album in which a photograph is sandwiched between a mount and a transparent film, and a method for manufacturing the album.

  Conventionally, as shown in FIGS. 14, 15, and 16, albums 32, 33, and 34 are used in which a photograph S is sandwiched between a paper mount 30 and a transparent film 31 (FIGS. 14 to 16). In the figure, a part of the film 31 is omitted, and the film side surface 30a of the mount 30 is shown).

  In the album 32 of FIG. 14, the glue 35 is applied to a plurality of locations in the form of vertical lines on the film-side surface 30 a of the mount 30. In the album 33 in FIG. 15, the paste 35 is applied to the surface 30 a on the film side of the mount 30 at a plurality of locations in an oblique line shape.

  In the albums 32 and 33 in FIGS. 14 and 15, it is difficult to remove the air X that has entered between the mount 30 and the film 31, and the presence of the air X causes the mount 30 to dry and lose its adhesive force, or the air X exists. There is a problem that the photograph S is not clearly seen because the light is reflected at the part where the light is applied.

  The album 34 in FIG. 16 was developed to solve the above-described problem, and the paste 35 is applied to the film-side surface 30a of the mount 30 in a substantially lattice shape. In this album 34, the glue 35 is not applied to the intersection of the lattice, or the thickness of the glue 35 is increased to about 14 to 18 μm as shown in FIG. By enlarging, the passage of air is secured.

  As another album having air passages, an album in which embossing is performed on a mount and paste is applied to the embossed convex portion has been developed. As such an album, there are an album obtained by embossing a PET laminate mount, and an album obtained by embossing a non-laminate paper mount as disclosed in Patent Document 1.

Japanese Utility Model Publication No. 35-12234

  However, in the albums 33 and 34 shown in FIGS. 15 and 16, the amount of glue 35 applied is large because the glue 35 is applied to a plurality of locations in the form of vertical lines or grid lines. For this reason, in the albums 33 and 34 of FIGS. 15 and 16, a large force is required to peel the film 31 from the mount 30, and a loud sound is generated when the film is peeled off. Moreover, since the application amount of the paste 35 is large as described above, the material cost of the paste 35 is expensive.

  Further, in the album 34 of FIG. 16, the paste 35 is applied thickly, so that the writing tool jumps with the glue line or the glue line cannot be traced with the writing tool, and the writing line T is interrupted. Further, in the album 34 of FIG. 16, for example, if the application thickness of the glue 35 is reduced to improve the writing property, the surface 30a of the mount 30 is flat, so that the gap between the mount 30 and the film 31 is small. Thus, it becomes difficult to remove the air between the mount 30 and the film 31. From the above, in the album 34 of FIG. 16, it is difficult to achieve both the improvement of writing performance and the extraction of air.

  Further, in the album 34 of FIG. 16, a paste containing natural latex, an acrylic ester copolymer and water is used as the glue 35, the content of natural latex is 7 to 13% by mass, and the acrylic ester copolymer is used. Was 23 to 27 mass%, and the water content was 63 to 66 mass%. The glue 35 has an adhesive strength of 0.80 N to 1.50 N due to the high content of the acrylate copolymer, and this also causes the peeling sound of the film 31 to increase.

  In an album using a PET laminate mount (hereinafter referred to as a PET album), a primer is coated on the PET laminate mount in order to improve the adhesion between the glue and the PET laminate mount. For this reason, the PET laminate mount has a low writing property and it is difficult to directly write characters and the like.

  In addition, when manufacturing PET albums, the process of obtaining a PET laminate mount by pasting a PET film on paper, the process of coating a primer on the PET laminate mount, the process of embossing the PET laminate mount, The process of apply | coating glue to the convex part of is required. For this reason, many processes are required for manufacture. Moreover, material cost becomes high by using a PET film and a primer.

  Further, Patent Document 1 does not disclose anything about the shape of the embossed convex portion or the applied thickness of the glue, nor is it intended to improve the writing property of the mount. In the album of Patent Document 1, when a large amount of glue is applied to many convex portions, the amount and area of the glue applied are increased, and the writing property is lowered.

  The present invention has been made in view of the above matters, and its purpose is to have high writing performance in the mount, and it is possible to evacuate the air between the mount and the film, and a loud sound is produced when the film is peeled off. It is to provide an album that does not occur.

  Improving the writing ability on the mount is a unique issue that was not conceived by conventional albums. As a result of earnest research, the inventor of the present application has improved the above-mentioned writability and does not generate a loud sound when removing the air between the mount and the film, which has been a problem in conventional albums. Made it feasible.

That is, the album according to the first aspect of the present invention includes a mount made of paper and a transparent film superimposed on the mount, and the film-side surface of the mount has an arcuate cross section by embossing. projecting convex portion is formed to have a height of not more than than 0.02 mm 0.027 mm, the apex of each of the convex portions, glue Ru is applied with a thickness of 14μm or more 10 [mu] m.

  Preferably, on the film side surface of the mount, a convex arrangement region in which the convex portions are arranged vertically and horizontally and a flat region without the convex portions are formed by embossing, and the flat region is formed. A grid pattern is drawn to divide the convex array region.

  Preferably, the outer edge of each convex portion has a square shape in a plan view, and the length of the side of the outer edge of each convex portion is 0.6 mm to 1.0 mm.

  Preferably, the paste includes natural latex, an acrylic ester copolymer, an aromatic-modified terpene hydrocarbon resin, and water, and the content of natural latex is 18% by mass or more and 21% by mass or less, The content of the acrylic ester copolymer is 12% by mass to 14% by mass, the content of the aromatic modified terpene hydrocarbon resin is 2% by mass to 4% by mass, and the content of water is 62% by mass to 65% by mass. % Or less.

  In the album manufacturing method according to the second aspect of the present invention, a projecting portion having a height of 0.02 mm or more and 0.027 mm or less is formed on one surface of the mount by projecting in an arc shape by embossing. An embossing step, a paste applying step of applying a paste to a thickness of 10 μm or more and 14 μm or less on the apex of each convex portion, a drying step of drying the paste applied in the paste applying step, and the drying step And a superposing step of superposing a transparent film on one surface of the mount.

  Preferably, the embossing process, the glue applying process, the drying process, and the superimposing process are performed in a process in which the mount is conveyed by a roll.

Preferably, in the embossing step, the mount is passed between an embossing roll having a recess formed on the surface and another roll, and the embossing roll and the other roll are sandwiched between the embossing roll and the other roll at the time of passing. By applying this pressure, one surface of the mount is projected into the recess of the embossing roll, and the protrusion is formed on one surface of the mount .

  Preferably, the surface of the embossing roll is formed with a recessed portion arrangement region in which the recessed portions are arranged vertically and horizontally and a flat region without the recessed portion.

  Preferably, the opening edge of the recess of the embossing roll has a square shape in a plan view, and the length of the side of the opening edge of the recess is 0.6 mm to 1.0 mm.

  Preferably, in the glue application step, the mount is passed between a glue roll and another roll, and the vertex of the convex part is brought into contact with the glue adhesion surface of the glue roll during the passage, A paste is applied to the apex of the convex portion.

  According to this invention, the convex part which protrudes in cross-sectional arc shape is formed in the film side surface of a mount by embossing, and glue is attached only to the vertex of a convex part. For this reason, the slope of a convex part and the recessed part of embossing will be in the state which paper exposed. Therefore, the area where the paste is not applied per unit area of the mount surface is wide. For this reason, the area of the portion writable by the mount becomes wide. Further, since the applied thickness of the glue is as thin as 10 μm or more and 14 μm or less, the level difference of the glue is small. For this reason, the writing instrument does not jump at the position of the glue, and the writing line is not interrupted. From the above, the album of the present invention has high writing performance of the mount.

  Moreover, in the album of this invention, a convex part has the height of 0.02 mm or more and 0.027 mm or less, and a film is supported by this convex part. For this reason, there is a gap about the height of the convex portion between the mount and the film, and an air passage is ensured. Thereby, the air between the mount and the film can be extracted. In addition, since the convex portions are formed, it is not necessary to increase the application thickness of the glue, and a passage for air can be secured. Therefore, it is possible to improve both the writing property and the air.

  Further, since the air between the mount and the film can be removed, it is possible to prevent the photograph from being clearly seen due to light reflected by the air.

  In addition, since the paste is applied only to the apexes of the convex portions, the amount of the paste applied and the application area are small. Furthermore, since the film is suspended from the middle of the inclined surface of the convex portion, the entire surface of the film does not adhere to the mount. From the above, the album of the present invention does not require a large force to peel off the film, and no loud sound is produced when the film is peeled off.

  Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a plan view showing an album 1 according to an embodiment of the present invention, with a part of a film 3 described later being omitted. FIG. 2 is a side view showing the album 1 according to the embodiment of the present invention.

  The album 1 according to the present embodiment includes a mount 2 made of paper and a transparent film 3. As shown in FIG. 2, the mount 2 is folded in half, and the back surface 4 a of the upper half part 4 and the back surface 5 a of the lower half part 5 are bonded. The film 3 is folded in two along the bent ends (ends of the upper half 4 and the lower half 5) of the mount 2, and is superimposed on the surface 4b of the upper half 4 and the surface 5b of the lower half 5. . Hereinafter, the surfaces 4b and 5b of the upper half 4 and the lower half 5 on which the film 3 is overlaid are collectively referred to as the surface of the mount 2 on the film 3 side.

  In the album 1, as shown in FIG. 2A, the photograph S can be sandwiched between the upper half 4 and the film 3, or between the lower half 5 and the film 3. ), The film 3 is peeled off from the mount 2 (the upper half 4 and the lower half 5), so that the photograph S can be arranged on the mount 2 (the upper half 4 and the lower half 5) S can be removed.

  FIG. 3 is an enlarged view of a range of FIG. 4 is a cross-sectional view showing a state in which the album 1 is cut along the line aa in FIG. FIG. 5 is an enlarged sectional view showing the convex portion 6 formed on the mount 2. FIG. 6 is an enlarged plan view showing the convex portion 6.

  Unevenness is formed on the surface of the mount 2 on the film 3 side by embossing. As shown in FIG. 3, the outer edge of each embossed convex portion 6 has a square shape in plan view. The length A of the outer edge side of each convex portion 6 is 0.6 mm to 1.0 mm, and is preferably set to 0.8 mm. As shown in FIGS. 4 and 5, each protrusion 6 protrudes in a circular arc shape in cross section. The height B (FIG. 5) of each convex part 6 is 0.02 mm or more and 0.027 mm or less. This height B corresponds to 1/40 to 1/30 of the side length A (0.8 mm) of the convex portion 6.

  Adhesive 7 is applied to the apex 6 a of each convex portion 6. The glue 7 is applied to attach the photograph S or the film 3 to the mount 2. The coating thickness C (FIG. 5) of the glue 7 in each convex part 6 is 10 μm or more and 14 μm or less, preferably 12 μm.

  As shown in FIG. 6A, the glue 7 is applied in a substantially rectangular shape, for example. Or as shown in FIG.6 (b), the glue 7 may be apply | coated circularly. The width D (FIG. 5) of the glue 7 is set according to the length A of the side of the convex portion 6. When the length A is 0.8 mm, the width D of the glue 7 is For example, it is set to 0.65 mm. The glue 7 is applied only to the apex 6a of the convex part 6, and the glue 7 is not applied to the slope 6b of the convex part 6 and the embossed concave part 8 (FIG. 4), and the paper is exposed.

  The paste 7 contains natural latex, an acrylic ester copolymer, an aromatic modified terpene hydrocarbon resin, and water. For example, the content of natural latex is 18% by mass to 21% by mass, the content of acrylic acid ester copolymer is 12% by mass to 14% by mass, and the content of aromatic modified terpene hydrocarbon resin is 2% by mass. The content of water is set to 4 mass% or less and the water content is set to 62 mass% or more and 65 mass% or less. In this case, the adhesive strength of the glue 7 is about 0.30N to 0.60N.

As shown in FIGS. 1 and 3, on the surface of the mount 2 on the film 3 side, a convex region R1 in which convex portions 6 are arranged at a predetermined pitch by embossing, and a flat region without the convex portions 6. R2 is formed, and a grid pattern is drawn in which the flat region R2 becomes the dividing line of the convex portion arrangement region R1. The grid pattern is a guideline for determining the attachment position of the photograph S. For example, the width E of the vertical and horizontal protrusion arrangement region R1 is 4.6 mm, the width F of the flat region R2 is set to 0.2 mm, the convex portion arrangement region R1, the arrangement pitch G of the projections 6 are protrusions 6 are 1 / 10-1 / 16 of the side length a (0.8 mm). In addition, the width E of the convex portion arrangement region R1 can be set to a width of 4.6 mm to 7 mm.

  FIG. 7 is a schematic diagram showing an apparatus for manufacturing the album 1 according to the present embodiment. Hereinafter, the manufacturing process of the album 1 will be described.

  The manufacturing apparatus shown in FIG. 7 conveys the backing sheet 2 by rotating a plurality of rolls, and in the process of transporting the backing sheet 2, an embossing process, a first glue application process, a first drying process, which will be described later, A second glue application step, a second drying step, and an overlay step are sequentially executed. Hereinafter, these steps will be described in order.

  In the embossing process, the base paper of the mount 2 is drawn out from the scroll 9 and the one surface 2a of the mount 2 is embossed.

  FIG. 8 is an enlarged sectional view showing the embossing roll 10 and the rubber roll 11 used in the embossing process. FIG. 9 is an enlarged plan view showing the surface of the embossing roll 10. FIG. 10 is a cross-sectional view of the embossing roll 10 taken along the line aa in FIG.

  As shown in FIGS. 8 and 9, a plurality of recesses 12 are formed on the surface of the embossing roll 10. In the embossing process, as shown in FIG. 8, the mount 2 is passed between the emboss roll 10 and the rubber roll 11, and a predetermined pressure is applied to the mount 2 by being sandwiched by the rolls 10, 11 at the time of passing. One surface 2a of 2 is protruded into the concave portion 12 to form a convex portion 6 having an arcuate cross section.

  As shown in FIG. 9, the opening edge of the recess 12 has a square shape in plan view. The length H of the edge of the opening edge of the recess 12 is 0.6 mm to 1.0 mm, preferably set to 0.8 mm. The outer edge of the convex portion 6 formed in the embossing process coincides with the opening edge of the concave portion 12.

  Moreover, although the depth I (FIG. 10) of the recessed part 12 is set to 22.2 mm or more and 30.0 mm or less, for example, the height B (FIG. 5) of the convex part 6 obtained by an embossing process is the above-mentioned. It does not coincide with the depth I of the recess 12. This is because the pressing force is limited so that the surface 2 a of the mount 2 does not protrude to the bottom of the recess 12, and the restoring force is applied to the mount 2 after pressurization (after the mount 2 passes between the rolls 10 and 11). Is caused by In the embossing process, the height B of the convex portion 6 is about 0.09% of the depth I of the concave portion 12 (the height B of the convex portion 6 is 0.02 mm or more and 0.027 mm or less). ), The pressure applied to the mount 2 and the speed at which the mount 2 is conveyed are adjusted. In addition, when the height B of the convex part 6 is lower than 0.02 mm, it becomes difficult to remove the air between the mount 2 and the film 3. Moreover, when the height B of the convex part 6 is higher than 0.027 mm, the adhesiveness between the film 3 and the mount 2 is lowered.

  Further, as shown in FIG. 9, the surface 10 a of the embossing roll 10 is formed with a recessed portion arrangement region R <b> 3 in which the recessed portions 12 are arranged vertically and horizontally and a flat region R <b> 4 without the recessed portions 12. The concave array region R3 and the flat region R4 are provided to form the convex array region R1 and the flat region R2 on the mount 2 and draw a grid pattern.

  The vertical and horizontal width J (FIG. 9) of the concave array region R3 defines the vertical and horizontal width E (FIG. 3) of the convex array region R1, and is set to a width of 4.6 mm to 7 mm, for example. The width K (FIGS. 9 and 10) of the flat region R4 determines the width F (FIG. 3) of the flat region R2, and is set to 0.2 mm, for example. The arrangement of the concave portions 12 in the concave portion arrangement region R3 determines the arrangement of the convex portions 6 in the convex portion arrangement region R1. In the recess arrangement region R3, the recesses 12 are arranged vertically and horizontally at a pitch L (FIG. 9, FIG. 10) of, for example, 0.08 mm or more and 0.013 mm or less.

  After the embossing process, the glue 23 is applied to the other surface 2b of the mount 2 that has not been embossed (first glue applying process). The other surface 2b of the mount 2 becomes the back surfaces 4a and 5b (FIG. 2) of the upper half 4 and the lower half 5 when the mount 2 is folded in a half-folding process described later.

  In this first glue application step, as shown in FIG. 11, the mount 2 is passed between the rubber roll 13 and the glue roll 14, and the other surface 2 b of the mount 2 is attached to the glue-adhering surface of the glue roll 14 during the passage. The paste 23 is applied to the surface 2b of the mount 2 by being brought into contact with 14a.

  Then, in the first drying step, as shown in FIG. 7, the mount 2 is put into the drying furnace 15, and the glue 23 applied to the surface 2b of the mount 2 in the first paste applying step is dried.

  Then, in the second glue application step, as shown in FIG. 12, the mount 2 is passed between the rubber roll 16 and the glue roll 17, and the apex 6a of the convex part 6 is passed through the glue adhering surface 17a of the glue roll 17 during the passage. The paste 7 is applied to the apexes 6a of the respective convex portions 6 by being brought into contact with each other. In this second glue applying step, the amount of glue to be attached to the glue roll 17 and the force for pressing the backing sheet 2 against the glue roll 17 are adjusted, so that the application thickness C of the glue 7 (FIG. 5) is 10 μm or more and 14 μm. The width D of the glue 7 (FIG. 6) is adjusted to about 0.65 mm.

  Then, in the second drying step, as shown in FIG. 7, the mount 2 is again put into the drying furnace 15, and the glue 7 applied to each convex portion 6 in the second paste applying step is dried.

  Next, in the superimposing step, the base paper 2 and the film 3 are passed between the rubber rolls 18 and 19 so as to be in close contact with each other, so that the film 3 is superposed on one surface of the base paper 2.

  Subsequently, the cutting machine 20 cuts the polymer of the mount 2 and the film 3 into predetermined dimensions (cutting process). Next, the cut polymer is folded in half by a folding machine 21 and the back surfaces of the upper half 4 and the lower half 5 to which the glue 23 is adhered are adhered to each other (a double folding step). Thereafter, the finishing machine 22 performs finishing cutting to complete the production of the album 1.

  As mentioned above, according to this embodiment, the convex part 6 which protrudes in cross-section circular arc shape is formed in the surface by the side of the film 3 of the base_sheet | mounting_paper 2, and the glue 7 is attached only to the vertex 6a of the convex part 6. FIG. For this reason, as shown in FIG. 4, the slope 6b of the convex part 6 and the embossed concave part 8 are in a state where the paper is exposed. Therefore, the area where the paste 7 is not applied per unit area on the surface of the mount is wide. For this reason, the area of the writable portion on the mount 2 is increased. Further, since the application thickness C (FIG. 5) of the glue 7 is as thin as 10 μm or more and 14 μm or less, the level difference of the glue 7 is small. For this reason, the writing instrument does not jump at the position of the glue 7, and the writing line T (FIG. 1) is not interrupted. From the above, the album 1 of the present embodiment has a high writing property of the mount 2.

  Moreover, in the album 1 of this embodiment, the convex part 6 has the height B (FIG. 5) of 0.02 mm or more and 0.027 mm or less, and the film 3 is supported by this convex part 6. FIG. Therefore, as shown in FIG. 4, there is a gap about the height of the convex portion 6 between the mount 2 and the film 3, and a passage for air is secured. Thereby, the air between the mount 2 and the film 3 can be extracted. Further, by forming the convex portion 6, it is not necessary to increase the coating thickness of the glue as in the album 34 shown in FIGS. 16 and 17, and the passage of air can be secured. Therefore, it is possible to improve both the writing property and the air.

  Further, since the air between the mount 2 and the film 3 can be removed, it is possible to prevent the photograph S from being clearly seen due to light being reflected by the air.

  Moreover, since the glue 7 is applied only to the apex 6a of the convex portion 6, the application amount and the application area of the glue 7 are small. Furthermore, as shown in FIG. 4, since the film 3 is suspended from the middle of the inclined surface of the convex portion 6, the entire surface of the film 3 does not adhere to the mount 2. From the above, the album 1 of this embodiment does not require a large force to peel off the film 3, and no loud sound is produced when the film is peeled off. Moreover, since the application amount of the glue 7 is small as described above, the material cost of the glue 7 can be kept low.

  Moreover, the film 3 and the photograph S can be stuck to the mount 2 even if the adhesive force of the glue 7 is not strong by appropriately adjusting the interval between the convex portions 6 to which the glue 7 is applied. For this reason, an adhesive having an adhesive strength of about 0.30N to 0.60N can be used.

  As shown in FIGS. 1 and 4, since the grid pattern is drawn by the convex arrangement region R1 and the flat region R2 on the mount 2, the user can determine the attachment position of the photograph S using the grid pattern as a guide.

Further, as the PET album described above, it or pasting PET film to the paper, no need to co computing a primer to mount. For this reason, the album 1 of the present embodiment has fewer steps required for manufacturing than the PET album, and the manufacturing cost can be reduced.

  Moreover, according to the manufacturing method of this embodiment, an embossing process, a paste application process, a drying process, and an overlaying process are sequentially performed in the process in which the mount 2 is conveyed by a roll. For this reason, many albums 1 can be manufactured in a short time without the effort.

  Further, in the embossing process, the convex portion 6 having a desired height can be formed on the mount 2 by adjusting the pressure applied to the mount 2 and the speed at which the mount 2 is conveyed.

  Moreover, the convex part 6 which has a desired planar shape can be formed by adjusting the shape of the opening edge of the recessed part 12 of the embossing roll 10. FIG.

  Further, by forming the concave array region R3 and the flat region R4 on the embossing roll 10, the convex array region R1 and the flat region R2 can be formed on the mount 2, and a grid pattern can be drawn.

  Moreover, since the mount 2 is strongly compressed by embossing, the hygroscopicity of the mount 2 is suppressed.

  In the second glue application step, the amount of glue to be attached to the glue roll 17 and the force for pressing the backing sheet 2 against the glue roll 17 are adjusted to adjust the application thickness C and width D of the glue 7 (FIG. 5). Can be adjusted to a desired value.

  In addition, this invention is not limited to the said embodiment, Various modifications can be made.

  For example, in the embossing process, embossing may be performed by pressing an embossing die against a base paper of a flat board. In the method using the embossing roll 10 shown in the above embodiment, since the time for the embossing to contact the mount 2 is shorter than the method using the embossing mold, the convex portion 6 having a small corner and rounded can be formed on the mount.

  Further, in the embossing process and the first and second glue application processes, a paper roll may be used instead of the rubber rolls 11, 13, and 16.

Further, the grid pattern may not be drawn on the mount 2. In this case, for example, as shown in FIG. 13, the backing sheet 2, the entire surface of the film side, the convex portion 6 is Ru are array.

  Moreover, although the example using the double fold mount 2 was shown in the said embodiment, the mount without a fold may be used. In this case, for example, the album is obtained by embossing (formation of convex portions 6) and applying glue 7 on the upper and lower surfaces of the mount, and the film 3 is superimposed on the upper and lower surfaces of the mount.
