Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a thick-page book such as an album, a photo album, and a picture book, and a bookbinding apparatus for the thick-page book. In the present specification, "thick page book" is a generic term for books including thick pages reinforced by reinforcing cardboard.

[0002]

2. Description of the Related Art A general album is a book with a cover, a back ball, and a back cover, which are attached to each other on the back side by attaching photographs to a large number of cardboard mounts each having a size of one page. It was done. However, in such a conventional album, since the left and right sides of the spread surface are formed by different mounts, it is unsightly if a large continuous photo is pasted on the left and right pages because a gap is formed at the seam. Further, in the case of producing a large number of copies, it takes a lot of work to attach a large number of photographs to each page.

Therefore, recently, an image taken by a camera or the like is laid out on a computer screen and printed out on a high-quality paper, and the print paper is bound into an album or a photograph printed on the photographic paper is bound up. It is also used as an album. However, when the size of the print paper is set to one page, when a series of photographs are placed on the left and right pages, there is a gap between the joints and it becomes unsightly. It is also possible to put large continuous photos on the left and right pages by using a print paper with a size of two pages spread, but the paper that can be printed by the printer is limited in thickness, so it is possible to use two papers back to back. Even if the sheets were stuck together, there was not enough waist, and it was not possible to make an album with a profound feeling and a high-class feeling.

[0004]

SUMMARY OF THE INVENTION The present invention solves the above-mentioned problems of the prior art, and allows printed photographs to be placed on the left and right pages, and has a profound feeling and a high-class feeling. It was made for the purpose of providing a thick page book. Another object of the present invention is to provide a bookbinding apparatus suitable for mass-producing such thick pages.

[0005]

The thick-page book of the present invention, which has been made to solve the above-mentioned problems, has a plurality of printing papers, each of which has a size of two pages and which is V-folded at the center, on each back surface. In between 1
A thick-paged book made by adhering reinforcing cardboard of a size corresponding to the number of pages, in which the center of each printed paper is placed on the back side of the book rather than the end of the reinforcing cardboard, and It is characterized in that it is projected as described above.

The thick-page bookbinding apparatus of the present invention is a thick-page bookbinding apparatus in which V-folded print paper and reinforcing cardboard are glued by a gluing roller and glued sequentially. The gluing roller is a roller having a large number of concave portions on its surface. In addition, it is preferable that the pressure roller arranged to face the gluing roller is elastically supported so as to be movable according to the difference in thickness between the print paper and the reinforcing cardboard.

The thick-page book of the present invention is formed by inserting a plurality of sheets of print paper, each of which has a size of two pages and which is V-folded in the center, so that when opened, it becomes a single-page spread print paper. , It is possible to put continuous print photos on the left and right pages. In addition, since a reinforcing cardboard having a size of one page is bonded and bound between the backs of the respective print sheets, the booklet can have a sufficient thickness, and a thick page book with a heavy feeling and a high-class feeling can be obtained. . Moreover, since the central portion of each print paper is projected to the back side more than the end portion of the reinforcing cardboard by the thickness of the reinforcing cardboard or more,
When opened, the reinforcing cardboards on both sides do not interfere with each other and can be opened in a full flat state.

As described above, since the thick page book of the present invention is made by alternately pasting papers having greatly different thicknesses, it cannot be glued well with a normal bookbinding apparatus, and the thick paper and the pressure roller cannot be glued together. When the reinforcing cardboard is passed through the gap, the glue may be strongly pushed out and adhere to the pressure roller, resulting in a defective product. However, according to the bookbinding apparatus of the present invention, since excess glue can be absorbed in the large number of concave portions on the surface of the gluing roller, it is possible to efficiently bind a large number of books without generating defective products.

BEST MODE FOR CARRYING OUT THE INVENTION Preferred embodiments of the present invention are shown below. FIG. 1 is a perspective view showing an album which is a thick page book of the present invention, FIG. 2 is an enlarged cross-sectional view of the vicinity of the back portion, and FIG. 3 is an explanatory view of an opened state. In these drawings, reference numeral 1 denotes a plurality of print sheets each having a size of two pages and folded in a V shape in the center. On the print paper 1, a photograph image taken by a camera or the like, which is laid out on a computer screen, is printed together with characters and illustrations. In the present specification, the print paper includes a photographic image printed by a printer, a color copier, and a photograph printed on photographic paper. Since the print paper 1 has a size of two pages and can be opened in a full flat state as shown in FIG. 3, continuous print photographs can be placed on the left and right pages.

Since these print papers 1 are made of high-quality paper or photographic paper, they are not sufficiently flexible. Therefore, in the album of the present invention, a reinforcing cardboard 2 having a thickness corresponding to one page is adhered between the back surfaces of the print paper 1 so as to have a waist. Then, as shown in FIG. 2, the center of each print paper 1 is located on the back side of the album rather than the end of the reinforcing cardboard 2.
The reinforcing cardboard 2 is interleaved by projecting the thickness of the cardboard 2 or more.
3 and 4 are facing sheets, 5 is spine cardboard, 6 is a cover material, and 7 is a core.

As described above, the thick-page book of the present invention can have a sufficient thickness by adhering the reinforcing thick paper 2 between the respective back surfaces of the print paper 1, so that the thick-page book has a heavy and luxurious feeling. It becomes a page book. Further, since the central portion of each print paper 1 is made to project more than the end portion of the reinforcing cardboard 2 by the thickness of the reinforcing cardboard 2, the reinforcing cardboards 2 interfere with each other even when opened as shown in FIG. Or, the print paper 1 can be opened in a full flat state without being pulled. The thickness equal to or larger than the thickness of the reinforcing cardboard 2 means about 1 to 5 times, preferably about 1.1 to 2 times the thickness of the reinforcing cardboard 2.

As described above, the thick-page book of the present invention can have continuous printed photographs on the left and right pages, and has a profound feeling and a high-class feeling. Therefore, a commemorative album, a graduation album, a photo album, etc. Is suitable as
It is also suitable for photo books and picture books.

In order to bind the above-mentioned thick-page book, a plurality of V-shaped folded print papers 1 and a thick reinforcing cardboard 2 are alternately glued and sequentially bonded. Since the thickness of the print paper 1 and the thickness of the reinforcing cardboard 2 are extremely different from each other, it is not possible to properly interleave the paper with a normal bookbinding apparatus. Therefore, the bookbinding apparatus of the present invention has the following special device.

FIG. 4 is a diagram showing an embodiment of the bookbinding apparatus of the present invention. This bookbinding apparatus is a V-folded print paper 1.
The reinforcing cardboard 2 and the reinforcing cardboard 2 are pasted together by the pasting mechanism 10 and are sequentially pasted together by the collating and pasting mechanism 20 below. The gluing mechanism 10 scoops glue from a gluing roller 11 that is in contact with the gluing surface of paper, a pressure roller 12 that faces the gluing roller 11, a sizing roller 13 that is disposed behind the gluing roller 11, and a glue container 14. A glue roller 15 for raising is provided.

The V-folded print paper 1 and the reinforcing cardboard 2 are alternately fed between the gluing roller 11 and the pressure roller 12, and are glued to the left surface of FIG. 4 by the gluing roller 11. , Lower collating and laminating mechanism 2
Dropped to 0. As shown in FIG. 5, the pressure roller 1
The spring 2 is pressed toward the stopper 17 by the spring 16 and maintains a constant space corresponding to the print paper 1 with the gluing roller 11, but when a thick reinforcing cardboard 2 passes through. As shown in FIG. 6, the pressure roller 12 retracts against the spring 16 to absorb the difference in thickness.

However, when the thick reinforcing cardboard 2 passes between the gluing roller 11 and the pressure roller 12, the contact pressure between the gluing roller 11 and the reinforcing cardboard 2 becomes high,
Excessive glue swells up and adheres to the pressure roller 12 as it is, causing defective products. Therefore, in the present invention, the gluing roller 11 is a roller having a large number of concave portions 18 uniformly formed on the surface thereof as shown in FIG. 8 so that excess glue can be absorbed therein. The shape and arrangement of the concave portion 18 are not particularly limited, and may be a groove such as a diagonal mesh or a set pattern of dots as long as the excess glue can be absorbed inside. However, if it is a continuous groove in the vertical direction, excess glue cannot be absorbed. As a result, even when the thick reinforcing cardboard 2 is passed through the gluing mechanism 10, uniform gluing can be performed as with the thin print paper 1.

The printing paper 1 and the reinforcing cardboard 2 which are glued on one side by the gluing mechanism 10 are attached to the collating mechanism 20.
It is dropped on the front surface of the rocking plate 24. An arcuate cam-shaped guide 22 is provided below the guide 22, and the lower ends of the print paper 1 and the reinforcing cardboard 2 are supported by the guide 22. In the bookbinding apparatus of the present invention, this guide 22 can be slightly moved up and down by an appropriate lifting device 23 such as a cylinder or a solenoid. When the print paper 1 is received, the guide 22 is lowered, and when the reinforcing cardboard 2 is received, the reinforcing cardboard 2 is used. Increase by more than the thickness of. As a result, it is possible to perform collated paper in a state where the central portion of the print paper 1 is projected more than the end portion of the reinforcing cardboard 2 by the thickness of the reinforcing cardboard 2 or more.

As shown in FIGS. 4 and 7, the oscillating plate 24 is oscillated about a lower shaft 25 by a cylinder 26 to a vertical position indicated by an imaginary line, and the printed paper 1 and the reinforcing cardboard 2 to which the gluing is applied. Is pressed against the preceding paper and pasted together. In addition, the leaf spring 2 for detent is provided on the side surface of the rack 27.
8 is arranged to prevent the paper from returning together when the rocker plate 24 returns.

In this way, the printing paper 1 and the reinforcing cardboard 2 are alternately glued and bonded together, and then the outer cardboard 5, the cover material 6 and the core 7 are wrapped and bonded to the outside. Then, it becomes a thick page book of the present invention.

[0020]

As described above, the thick-page book of the present invention can carry continuous printed photographs on the left and right pages,
Moreover, the book has a profound and luxurious feel. Further, according to the bookbinding apparatus of the present invention, it is possible to mass-produce the thick page book of the present invention while uniformly gluing the print paper and the reinforcing cardboard having different thicknesses.
