Description

  The present invention relates to a bookbinding method (book production method) for bookbinding using an adhesive.

  Conventionally, as a bookbinding method for photo albums and albums, 1) an adhesive (emulsion system, glue, hot melt system, etc.) is applied to the back surface (or / and the surface of the core paper) of the printed material (photo) 2) the core The procedure of pasting the printed material on the paper, 3) folding the core paper in half so that the printed material is inside, 4) applying the adhesive to the back surface of the core paper, and 5) pasting the back surfaces of the core paper together is known. It has been. Such a bookbinding method is often used for personal bookbinding by an on-demand method such as a wedding anniversary album.

  In the above procedure, the core papers or the printed material are bonded to each other following the application of the adhesive to the core paper or the printed material. In this case, in order to stabilize the adhesive state, it is necessary to wait for drying (curing) of the adhesive after being fixed in a bonded state.

  However, the existence of such a standby process is a major factor that hinders the shortening of the period from order receipt to delivery. In particular, in on-demand bookbinding, which often requires delivery in a short period of time, the standby process tends to become a rate-limiting process substantially.

  SUMMARY OF THE INVENTION Accordingly, the present invention provides a framework that enables efficient bookbinding by shortening the period from order receipt to delivery when bookbinding is performed by sticking together core papers to which printed matter is pasted. The purpose.

  Here, since the adhesive may partially expand and contract as drying progresses, if it is simply fixed and dried in a bonded state, the paper may swell when the bonding is completed There is. Therefore, usually, a method is adopted in which the adhesive is dried by applying pressure to the paper surface with, for example, a weight, and the adhesive is dried to suppress the occurrence of the swell.

  However, even if the occurrence of undulation at the end of bookbinding can be suppressed to some extent, the expansion and contraction rate with respect to changes in temperature and humidity is greatly different between the paper normally used as the core paper and the adhesive (the core paper is The adhesive will expand and contract to some extent depending on the temperature and humidity, but the adhesive will not expand or contract after stabilization), resulting in waviness after bookbinding due to changes in temperature and humidity based on seasonal changes, etc. There remains a risk of coming.

  Therefore, a second object of the present invention is to provide a bookbinding technique that does not cause any warping not only at the end of bookbinding but also at the end of bookbinding.

  The bookbinding method of the present invention is a method of preparing a plurality of core papers to which printed matter is pasted and bonding them to each other, and applying adhesive adhesive to both the front and back surfaces of the core paper, each having a release paper. A step of bonding, a step of peeling off the release paper on the surface of the core paper and pasting the printed material, a step of folding the core paper with the surface on which the printed material is pasted inward so as to form a spread centering on the folding position, and folding And a step of arranging the plurality of core papers stacked, and a step of peeling the release paper on the back surface of the core paper and bonding the core papers together.

  Preferably, the core paper is synthetic paper.

  Also preferably, the adhesive adhesive is an adhesive that produces adhesiveness at room temperature.

  Preferably, the method includes a step of applying a sticky adhesive only to the surface of the core paper and bonding the release paper, and in the step of arranging the arrangement, when stacking a plurality of folded core papers, The core paper to which the adhesive adhesive is applied and the core paper to which the adhesive adhesive is applied only on the surface are stacked so as to be alternately arranged.

  Preferably, the release paper is affixed to the core paper in a state where it can be separated into three parts, a central part sandwiched between the left part, the right part, and the left and right parts.

  Preferably, the step of applying the printed material includes the step of peeling the central portion of the release paper on the surface to expose the core paper corresponding to the central portion, and the printed material corresponding to the left and right page positions of the core paper. The step of fixing the position of the printed matter using the adhesiveness of the portion corresponding to the central portion of the core paper, and the left part and the right part of the release paper on the surface with the position of the printed matter fixed And a step of completing the pasting of the printed matter.

  Preferably, the step of laminating the core papers corresponds to the step of peeling the central portion of the release paper on the back surface to expose the core paper corresponding to the central portion, and the central portion of the core paper. Using the adhesiveness of the parts to be fixed, the process of fixing the positions of the core papers, and with the positions of the core papers fixed, peel off the left and right parts of the release paper on the back, respectively, And a step of completing the bonding.

  The bookbinding jig of the present invention is a bookbinding jig used in the bookbinding method of the present invention, and is in contact with at least one of the vertical side or the horizontal side of the core paper, and the position of the core paper And a means for installing a bar-shaped jig for preventing interference between printed materials respectively attached to the left and right sides of the core paper.

  Another bookbinding jig of the present invention is a bookbinding jig used in the bookbinding method of the present invention, and includes a surface A, a surface B, and a surface C, and a plurality of folded core papers are stacked. When arranging the arrangement of the plurality of core papers, the bottom and end surfaces of the core paper bundle are slid while contacting the surface A and the surface B, and the back portion of the bundle is brought into contact with the surface C.

  ADVANTAGE OF THE INVENTION According to this invention, when binding the core paper which stuck the printed matter mutually, it can shorten the period from order receipt to delivery, and can bind efficiently. Further, it is possible to provide a bookbinding technique in which no warping occurs not only at the end of bookbinding but also after the bookbinding is completed.

  Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings. The bookbinding method of the present embodiment is configured by sequentially performing three steps of an adhesive application step, a printed matter sticking step, and a core paper sticking step.

  Hereinafter, each step will be described in detail with reference to FIGS. Note that the steps in each process (including partial processes to which no reference numerals are assigned) can be executed in any order or in parallel within a range that does not contradict the processing contents.

(Adhesive application process: Fig. 1)
First, the synthetic paper prepared for the core paper (for example, YUPO from YUPO Corporation, Peach Coat from Nisshinbo, Carle from Chisso, etc.) is cut into the spread size of the book to be bound, and the core paper is cut. Create (FIG. 1A).

  Synthetic paper is made of synthetic polymer material as a main material and processed to give paper properties and is used for paper applications. The degree of expansion and contraction with respect to changes in temperature and humidity is small compared to paper. . In this embodiment, since such synthetic paper is used for the core paper, even when the temperature or humidity changes due to seasonal changes or the like, undulation occurs due to the difference in expansion / contraction rate between the core paper and the adhesive. The possibility can be suppressed.

  Next, a sticky adhesive is applied to the side (core paper surface) to which the printed matter of the core paper is attached (FIG. 1B). However, as shown in FIG. 1B, a region (adhesive removal region) where no adhesive is applied is provided in a line (for example, about 3 to 4 mm width) in the center of the spread using a mask or the like. Such an adhesive removal region prevents the left and right spread prints from interfering with each other, and allows the pressure from the back of the book to be opened and closed when the book is opened and closed, thereby preventing the printed product from turning over and peeling off. .

  As the adhesive adhesive, it is desirable to use an adhesive (generally an emulsion or volatile adhesive) that generates adhesiveness at room temperature. Glue and hot melt adhesives are solid at room temperature, and when heated, they have sufficient fluidity for adhesion, and after application, the solvent evaporates or is absorbed by the substance to be bonded. Because it has the property that the adhesive is cured and adhesive force is generated, a heating process is required when applying, and in addition to making the work cumbersome, it is difficult to have tackiness at room temperature It is.

  As a method for applying the adhesive, an appropriate method may be adopted depending on the type of the adhesive. For example, the adhesive is applied to the core paper using a brush or the like if it is an emulsion type adhesive, or using a spray or the like if it is a volatile adhesive.

  In the experiment conducted by the applicant, the following two types of adhesives were used, and appropriate adhesive performance could be obtained even at room temperature and after the adhesive was stabilized.

(1) Product name “Nissetsu PE-154Y”
Manufacturer: Nippon Carbide Industries Co., Ltd. Chemical name: Vinyl acetate / (meth) acrylic acid alkyl ester copolymer solution Component and content: resin 30-40%, toluene 14%, ethyl acetate 50-60%

(2) Product name “Cybinol AT-523”
Manufacturer: Seiden Chemical Co., Ltd. Chemical name: Acrylic copolymer aqueous emulsion component and content: Acrylic copolymer 51.0%, Water 49.0%

  Next, the release paper is pasted to the core paper surface to which the adhesive is applied, and the state is maintained until the adhesive state of both is stabilized (if the adhesive is an emulsion adhesive, the adhesive is dried) (Waiting) (FIG. 1 (c)).

  As the release paper, a paper coated with an appropriate resin or the like according to the property of the adhesive can be used. However, the release paper used in the present embodiment is attached to the core paper in a state where it can be separated into three parts, that is, the central part sandwiched between the left part, the right part, and the left and right parts. As will be described later, the central part is peeled off to expose the corresponding part of the core paper, and the printed material and the core paper are partially pasted using the adhesiveness of that part to fix their positions. Used to do. In the example shown in FIG. 1, the central portion is provided in a line shape (for example, a line shape having a width of about 30 mm larger than the width of the adhesive removal region) so as to divide the left portion and the right portion.

  In order to attach the release paper to the core paper in a separable state, for example, a groove portion having a thickness that can be easily separated may be provided between each portion of the release paper. Alternatively, after the core paper and the release paper are bonded together, only the release paper may be cut so that the three parts can be separated.

  When the release paper has been bonded to the core paper surface, the release paper is also bonded to the side where the core papers are bonded (back surface of the core paper) in the same manner as shown in FIGS. FIG. 1 (d) and FIG. 1 (e)). However, since the printed material is not pasted on the back side of the core paper, it is not necessary to provide an adhesive removal region. Moreover, although the shape and size of the left part, the right part, and the center part can be the same as the core paper surface, they may be different. However, the central part is provided so as to at least divide the left part and the right part.

  Note that the cutting of the synthetic paper, the application of the adhesive to the core paper, and the bonding with the release paper may be performed manually or may be performed using a conventional pressure-sensitive adhesive sheet creating apparatus or the like.

  Moreover, it is good also as a structure which apply | coats an adhesive agent to a synthetic paper sheet | seat, cuts after bonding release paper, and produces a core paper. In this case, in consideration of the size of the core paper and the arrangement on the sheet, the adhesive is applied to the synthetic paper sheet so that the adhesive removal area is appropriately secured when the core paper is formed by cutting.

  The core paper coated with adhesive is prepared and stored as described above. As described above, in the bookbinding method of the present embodiment, the adhesive application process is separated as a process preceding the other processes. Therefore, only the adhesive application process is performed, and the core paper is previously prepared prior to the bookbinding request. It can be created.

(Printing process: Fig. 2)
First, an adhesive-coated core paper matching the size of the book to be bound is taken out from the storage location, and set on the printed material alignment jig 100 with the core paper surface facing up (FIG. 2A). ).

  In the alignment jig 100, the side edges in the vertical direction of the core paper are arranged so that the printed material and the core paper can be reliably aligned, that is, the position of the core paper can be fixed and set on the jig. Alternatively, a means for fixing the position of the core paper in contact with at least one of the left and right sides is provided. In the example shown in FIG. 2A, as the fixing means, linear raised portions 10 and 11 are provided above and below the alignment jig 100, and the interval between the raised portions 10 and 11 is set to the vertical width of the core paper. Is approximately the same. Further, the right and left width of the alignment jig is substantially matched to the left and right width of the core paper. Thus, if the core paper is placed between the raised portions 10 and 11 and the core paper is placed so as not to protrude from the jig 100, the position of the core paper is fixed on the jig 100 and set. It can be done.

  In addition, it is desirable to provide means for installing a rod-shaped jig 13 (described later) for preventing interference between printed materials attached to the left and right portions of the core paper at the left and right centers of the jig 100. In the example shown in FIG. 2A, as the means for installing, the upper and lower raised portions 10 and 11 are provided with groove portions 12 having a width (for example, about 1 mm) smaller than the width of the adhesive removal region.

  Next, using, for example, the groove 12, the central portion of the release paper on the surface of the core paper is peeled off, and the surface of the core paper corresponding to the central portion is exposed (FIG. 2B).

  Next, the printed material corresponding to each of the left and right spreads is placed on the core paper, and the printed material is partially attached using the adhesiveness of the portion corresponding to the exposed central portion of the surface of the core paper. Is fixed (FIG. 2C). At this time, before sticking the printed matter, or after sticking the left or right printed matter, before sticking the remaining printed matter, the rod-shaped jig 13 having a width smaller than the width of the adhesive removal region (for example, about 1 mm), For example, the groove portion 12 is used to set on the core paper. This is because the attachment position of the printed material can be determined with reference to the jig 13, and interference between the left and right printed materials can be prevented by the jig 13.

  Next, with the position of each printed matter fixed, the left and right portions of the release paper on the surface of the core paper are peeled off to complete the pasting of the entire printed matter (FIG. 2D).

  As described above, the corresponding printed matter is pasted on one core paper necessary for bookbinding.

(Core paper pasting process: FIGS. 3 and 4)
First, each of the one core paper to which the printed matter is attached is folded with the core paper surface inward so as to form a spread with the folding position as the center (that is, with the adhesive removal region as the center) (see FIG. 3 (a)).

  Next, a plurality of core sheets in a folded state are stacked in the order of the pages at the time of bookbinding so that the top and bottom are aligned, and the stack of core sheets stacked using the back-to-back jig 101 is flattened up and down. The arrangement is arranged (Fig. 3 (b)).

  The back-to-back jig 101 slides the bottom 20 and the end surface 21 of the bundle of core papers in contact with the surface A and the surface B when arranging the arrangement of a plurality of stacked core paper bundles. The surface A, the surface B, and the surface C are connected to form a right angle so that the top and bottom of the bundle and the back portion 22 can be made flat by bringing the surface 22 into contact with the surface C ( (Refer FIG.3 (b)).

  Here, when the release paper on the back side of the core paper is simply divided into two parts, the left part and the right part, when the core paper is bent, the release paper is peeled off as shown in FIG. There is a risk that the back may float. In this case, the degree of floating may differ depending on the core paper, and even if the surface C is used, it is difficult to arrange the back portion 22 to be flat. However, in the present embodiment, the release paper on the back surface of the core paper is provided with a central portion so as to divide the left portion and the right portion. Therefore, even when the core paper is folded, the back portion 22 is peeled off by the release paper. It does not float and can be appropriately arranged using the surface C so that the back portion 22 becomes flat.

  Next, with respect to the bundle of core papers, for example, by sandwiching the upper part with a clip or the like, the central part of the release paper on the back surface of each core paper is peeled off while maintaining the arrangement, and the part corresponding to the central part The back surface of the core paper is exposed (FIG. 3C).

  Next, using the adhesiveness of the portion corresponding to the exposed central portion on the back side of the core paper, the vicinity of the back portions of the adjacent core papers is partially bonded together to fix the positions of the core papers (FIG. 4 (a)).

  Next, in a state where the positions of the core papers are fixed, the left and right portions of the release paper on the back surface of the core paper are peeled off to complete the bonding of the core papers (FIG. 4B).

  Finally, the release paper on the back surface of the core paper located at the end is peeled off and bonded to the inner surfaces of the front cover and the back cover to complete bookbinding (FIG. 4C).

  In the bookbinding method of the present embodiment, since the adhesive application step is separated as a process preceding the printed matter application step and the core paper application step, only the adhesive application step is performed and the adhesive-coated core is previously applied. It is possible to create paper. In other words, according to the bookbinding method of the present embodiment, when an order is placed, only the printed material pasting step and the core paper pasting step are performed using the core paper coated with the adhesive prepared in advance. Perform and complete bookbinding. According to such a method, it is not necessary to apply an adhesive after ordering or to wait for it to dry. Therefore, the period from ordering to bookbinding completion (delivery) can be greatly shortened and bookbinding can be performed efficiently. it can.

  Further, as described above, in the bookbinding method of the present embodiment, the adhesive coating step is performed in advance, and the core paper is stored in a state where the release paper is bonded (that is, in a state where the adhesive is dry and stable). Therefore, it is unlikely that the drying of the adhesive proceeds (adhesive expansion and contraction) at the stage of the sticking process. Therefore, according to the bookbinding method of the present embodiment, it is possible to avoid the conventional problem that drying of the adhesive proceeds after sticking, and thereby the adhesive partially expands and contracts to cause undulation.

  Furthermore, in the bookbinding method of the present embodiment, since synthetic paper is used as the core paper, undulations that occur after the end of bookbinding, which is difficult to avoid with the conventional method, that is, changes in temperature and humidity based on seasonal changes, etc. The undulation caused by this can be greatly suppressed (the undulation can be substantially eliminated).

(Modification)
The present invention is not limited to the above-described embodiment, and can be variously modified and applied.

  For example, in the above-described embodiment, an adhesive is applied to the back surface of any core paper and the release paper is bonded, but the present invention is not necessarily limited to such an aspect. For example, the adhesive application process of the above embodiment, and in this process, the adhesive adhesive is applied only to the surface of the core paper, and the release paper is bonded, in which the steps of FIGS. 1 (d) and (e) are omitted. The core paper (core paper A) having the adhesive adhesive applied to both the front and back surfaces and the core paper (core paper B) having the adhesive adhesive applied only to the surface are prepared. Then, in the printed matter pasting step and the core paper pasting step, the printed matter is pasted and the core papers are superposed so that the core paper A and the core paper B are alternately arranged in a folded state in the bundle of core papers (FIG. 6). In this case, in the step of laminating the core papers, the adhesive is not applied to the back surface of the core paper B, but the adhesive is applied to the back surface of the core paper A that is the counterpart of the pasting. The core papers can be bonded together as in the above embodiment.

  Further, for example, in the adhesive application step of the above-described embodiment, the back side of the core paper may be configured such that the adhesive is applied only to the right half surface or the left half surface and the release paper is bonded. In the step of laminating the core papers, the right half of the back side of the core paper and the left half side of the other back side of the core paper are pasted together. Therefore, even if configured as described above, the core paper is the same as in the above embodiment. You can paste them together.
