Description

  The present invention relates to a method and an apparatus for gluing the back of a text in a booklet such as an album.

  In recent years, photo books called photo books have been bound and sold for individuals. This photo book consists of multiple sheets of paper, such as photographic paper on which negative images are baked, and printing paper on which photographs are printed by sublimation transfer, ink jet, etc., and a cover is added to this text as necessary. It is created by superimposing and binding the text and cover by various methods.

  As a sheet binding method, ring binding, saddle stitching or flat binding using a binding tool, wireless binding using an adhesive, and the like are appropriately employed.

  The ring-binding method is performed by sandwiching the body of the above-mentioned paper between cover sheets, punching them on the back, and passing a spiral ring or an annular ring through the many small holes that are made. Saddle-stitching or flat-stitching with tools is performed by sandwiching the text with a cover and inserting a metal needle into the back of the text, and wireless binding with glue or a die coat on the back of the text. Application is performed (for example, refer to Patent Document 1), and then a cover is attached to the main body.

  Embodiments of the present invention will be described below with reference to the drawings.

<Embodiment 1>
As shown in FIG. 1, the text 1 created by the gluing method according to the present invention is configured by superposing a plurality of relatively thick papers 2 such as photographic papers. The sheet 2 may have a resin coating on the surface.

  Each sheet 2 is preliminarily displayed with a photographic image on one side or both sides thereof. The photographic image is displayed by, for example, sublimation transfer printing or ink jet printing.

  On the back of the main body 1, a hot melt adhesive as a paste is applied as a coating film 3. When the coating film 3 is solidified, all sheets 2 of the text 1 are bound and integrated in a wireless binding state. Since the hot melt adhesive is glued by a gluing method to be described later, as shown in FIG. 1, the hot melt adhesive penetrates from the back end surface of the text 1 to between the sheets 2 and 2.

  As shown in FIG. 2, the text 1 is wrapped in a cover 4 to be finished into a photo book as a booklet.

  On the outer and inner surfaces of the cover 4, a photographic image similar to the paper of the text 1 is displayed as necessary.

  The front cover 4 is created as a front cover 4a, a back 4b, and a back cover 4c connected in one direction. Then, ruled lines 6 and 6 are press-formed in advance on the boundary lines of the front cover 4a, the back 4b, and the back cover 4c before bookbinding.

  The pasting of the body 1 is performed by the pasting method shown in FIGS.

  (1) First, as shown in FIG. 3A, the paper sheets 2 are overlapped by the number of sheets constituting the text 1 of one photobook, and the clampers 7 and 7 are prevented from being misaligned. It is clamped with. In this state, the back end surface of all sheets 2 extends as a single plane. In this case, the length of the back side of the bundle of sheets 2 protruding from the tips of the clampers 7 and 7 is preferably about 10 mm to 20 mm.

  (2) On the other hand, as shown in FIG. 3B, a hot melt adhesive is applied as a molten film 9 on the substrate 8.

  A heater (not shown) is embedded in the base 8 and the base 8 is heated by the heat generated by the heater. A stick-shaped hot melt adhesive 9a is applied to the base 8 with a scissors, so that the hot melt adhesive is melted and extends as a film 9. Thereby, the adhesive is provided on the base 8.

  The base 8 can be not only plate-shaped but also belt-shaped. Alternatively, a recess may be formed in the center of the base 8, and a hot melt adhesive film 9 may be formed in the recess.

  (3) As shown in FIG. 4 (A), the clamped body 1 is moved toward and away from the base 8 in a posture such that the back of the main body 1 faces the base 8. Of course, the base 8 may be moved with respect to the back of the body 1.

  The spine of the main body 1 is pressed against the hot melt adhesive film 9 when the main body 1 is lowered onto the base 8, and further pressed against the surface of the base 8.

  Thereby, the coating film 3 of the hot melt adhesive adheres to the back end face of the main body 1.

  (4) As shown in FIG. 4B, the clamped body 1 is shifted from the base 8 by a distance corresponding to one pitch in the extending direction of the base 8. Of course, the base 8 side may be shifted with respect to the text 1.

  Then, the clamped body 1 is moved up and down with respect to the base 8 in such a posture that its back faces the base 8 again.

  The spine of the main body 1 is pressed against the new film 9 of the hot melt adhesive when the main body 1 is lowered onto the base 8, and further pressed against the surface of the base 8.

  In this way, when the bundle of sheets 2 to which the adhesive is applied is pressed against another position on the base 8, the adhesive coating film previously applied to the end surface of the sheet 2 by the newly transferred adhesive. 3 is pushed between the sheets 2 and 2. Since the leading end portion of the bundle of sheets 2 is not restrained by the clampers 7, 7, the sheet 2 is pushed outward by the viscosity of the adhesive, so that the adhesive penetrates between the sheets 2, 2 more smoothly.

  (5) As shown in FIG. 4C, the clamped text 1 is further shifted by a distance of one pitch in the extending direction of the base 8 with respect to the base 8.

  Then, the clamped body 1 is moved up and down with respect to the base 8 in such a posture that its back faces the base 8 again. The spine of the main body 1 is pressed against the new film 9 of the hot melt adhesive when the main body 1 is lowered onto the base 8, and further pressed against the surface of the base 8.

  As a result, the hot melt adhesive penetrates between the back end face of the text 1 and the sheets 2 and 2 deeper than before.

  (6) As shown in FIG. 4D, the clamped text 1 is further shifted by a distance of one pitch in the extending direction of the base 8 with respect to the base 8.

  Then, the clamped body 1 is moved up and down with respect to the base 8 in such a posture that its back faces the base 8 again. The back of the main body 1 is pressed against the hot melt adhesive film 9 when the main body 1 is lowered onto the base 8, and further pressed against the surface of the base 8.

  As a result, the hot melt adhesive penetrates between the back end face of the text 1 and the sheets 2 and 2 more deeply than the previous time.

  The number of steps (3) to (6) is adjusted as necessary.

  In this manner, the hot melt adhesive is moved from the back end face of the text 1 to between the sheets 2 and 2 by repeating the lifting and lowering operation while shifting the text 1 relative to the base 8 in the extending direction of the base 8. And go deeper.

  (7) The text 1 bound by the hot melt adhesive is removed from the clampers 7 and 7. The text 1 released from the clampers 7 and 7 is supplied onto the cover 1 as shown in FIG. 5A, and the spine of the text 1 is applied to the spine 4b of the cover 4 through the hot melt adhesive film 9. It is done.

  Ruled lines 6 and 6 are formed in advance on the spine 4 b of the cover 4.

  (8) As shown in FIG. 5B, the cover 4 is folded on the ruled lines 6 and 6, and the text 1 is wrapped by the cover 4.

  (9) As shown in FIG. 5C, the back of the main body 1 is put on the heating plate 5 in a state where it is overlapped with the back 4b of the cover 4, and both sides of the back 4b are pressed by the press plates 10 and 10. . The hot melt adhesive coating film 3 on the back of the main body 1 is melted again by heat transfer from the hot platen 5, and the back of the main body 1 is firmly bonded to the back 4 b of the cover 4.

  Thereafter, the coating film 3 of the hot-melt adhesive is solidified, and the text 1 wrapped with the cover 4 is completed as a photo book.

  A gluing device for carrying out the gluing method is configured as shown in FIG.

  As will be described later, the gluing device also includes a cover attaching unit, and is configured as a bookbinding device as a whole.

  As shown in FIG. 6, the gluing device has a base 8 on which hot melt adhesive is applied so as to form a liquid film 9, and a body 1 that is formed by stacking and clamping sheets 2, with the base 8 on the back. Elevating means for making a close-to-separate operation, that is, an elevating operation a plurality of times relative to the base 8 after facing the substrate 8 is provided on a base (not shown).

  The base 8 is formed of a horizontal plate. This horizontal plate has a width that is several times the thickness of the spine of the text 1 and a length that is slightly larger than the length of the spine.

  Although not shown, the base 8 is provided with a heater. When the heat of the heater is transferred to the surface of the base 8, the stick-shaped hot melt adhesive 9 a applied to the surface of the base 8 is melted, and the liquefied hot melt adhesive becomes a film 9 to form the base 8. Spread on the surface of the.

  When a liquid paste other than the hot melt adhesive is used as the adhesive, the heater is omitted.

  On one side of the base 8, a reciprocating means for the hot melt adhesive 9 a solidified in a stick shape is arranged along the length direction of the base 8. The reciprocating means has an endless belt 11, and a stick-like hot melt adhesive 9 a is connected to the endless belt 11. The endless belt 11 is stretched between a pair of pulleys 13 and 13 rotatably held by a frame 12 extending along the longitudinal side surface of the base 8. A motor 14 is motively connected to one pulley 13, and the pulleys 13, 13 rotate forward and backward by the rotation of the motor 14, so that the stick-shaped hot melt adhesive 9 a is in contact with the surface of the substrate 8. Move in the long side direction.

  The endless belt 11 pulls the stick-shaped hot melt adhesive 9 a under the control of the motor 14, and the stick-like hot melt adhesive 9 a moves back and forth on the base 8. As a result, the stick-like hot-melt adhesive 9 a comes into contact with the surface of the substrate 8 and melts, and becomes a liquid film 9 that spreads on the surface of the substrate 8.

  On the side of the base 8 opposite to the side where the reciprocating means for the hot melt adhesive is provided, the reciprocating means for the clampers 7 and 7 is provided.

  The clampers 7 and 7 are a pair of pressing plates that sandwich the text 1 formed by stacking the sheets 2, and both pressing plates are connected by a fastener such as a screw (not shown). The clamper 7 holds the body 1 in a pressurized state as shown in FIG.

  The reciprocating means of the clampers 7 and 7 has a horizontal guide rail 15 extending along the long side direction of the base 8, and the clampers 7 and 7 are held by the horizontal guide rail 15 so as to be slidable in the horizontal direction. Although the clampers 7 and 7 can be reciprocated manually, the horizontal guide rail 15 is provided with an endless belt and a motor (not shown) for reciprocating the clampers 7 and 7 as necessary.

  The clampers 7 and 7 move in one direction or both directions on the horizontal guide rail 15 by manual operation or driving by a motor or the like while holding the body 1. The clampers 7, 7 stop when the spine of the main text 1 faces the coating 9 slightly above the coating 9 of the hot melt adhesive applied on the base 8.

  The horizontal guide rail 15 is held up and down by vertical guide rails 16 and 16 erected from a base (not shown). For this reason, the clampers 7 and 7 can be moved up and down along the vertical guide rails 16 and 16 together with the horizontal guide rail 15.

  The base 8 can be reciprocated along the short side direction of the base 8 by reciprocating means. This reciprocating means is arranged to move the cam 17 and the base 8 in a direction crossing the moving direction of the stick-like hot melt adhesive 9a by the reciprocating means of the stick-like hot melt adhesive 9a.

  The reciprocating means has guide rails 18 and 18 extending along the short side surface of the base 8 and is stretched between a pair of pulleys 19 and 19 rotatably held on the guide rail 18. It has an endless belt 20. A cam 17 is connected to the endless belt 20, and the base 8 is connected via the cam 17. A motor 21 is movably connected to one pulley 19, and the pulleys 19, 19 rotate forward and backward by the rotation of the motor 21, so that the cam 17 is in contact with the horizontal guide rail 15 and in the short side direction of the base 8. Moving. A cam follower (not shown) with which the cam 17 is in contact is formed at the lower portion of the horizontal guide rail 15.

  The cam 17 functions as an elevating means for moving the body 1 toward and away from the base 8, that is, ascending and descending, and a plurality of cams 17 are provided in series in the short side direction of the base 8. Four cams 17 are provided if the gluing method shown in FIG. 4 is employed. When the row of cams 17 is moved by driving the motor 21, the body 1 moves up and down with respect to the base 8 together with the clampers 7, 7 and the horizontal guide rail 15 whenever the cam 17 comes into contact with the cam follower of the horizontal guide rail 15. Along with this, the base 8 also moves in the short side direction in small increments.

  The horizontal guide rail 15 extends long beyond one short side of the base 8 in the orthogonal direction, and a cover attaching portion is disposed below the portion where the horizontal guide rail 15 extends.

  The cover attaching portion is provided as necessary. When omitted, the horizontal guide rail 15 is shortened and formed as a support beam for the clampers 7 and 7.

  The cover attaching portion includes a heating platen 5 as a receiving portion that receives the back of the main body 1 together with the back 4b of the cover 4 and a pair of press plates 10 and 10 that pressurize both sides of the back. A heater (not shown) is embedded in the hot platen 5. The cover attaching part can be moved up and down as a whole, and the press plates 10 and 10 can reciprocate in a state of being opposed in the horizontal direction.

  When gluing is completed on the spine of the body 1 held by the clampers 7 and 7 in the above-described pasting device, the clampers 7 and 7 slide on the horizontal guide rail 15 together with the body 1 to the cover attaching section. Therefore, when the cover 4 is inserted and positioned between the spine of the body 1 and the cover attaching portion, the cover attaching portion is raised and the body 4 and the spine 4b of the cover 4 are placed in the gap between the press plates 10 and 10. To introduce. Accordingly, the cover 4 bends upward, and then the press plates 10 and 10 press both sides of the back. Further, the heating platen 5 is heated by a heater, and by this heat, the spine coating film 3 of the text 1 is melted again, and the spine of the text 1 is firmly bonded to the spine 4 b of the cover 4.

  Note that the cover 4 may be attached to the text 1 by setting the cover attaching part at a fixed position and lowering the text 1 held by the clampers 7 and 7 to the cover attaching part.

  Thereafter, the press plates 10 and 10 are opened to release the body 1 to which the cover 4 is bonded, and then the cover attaching portion is lowered.

  When the hot-melt adhesive of the coating film 3 is solidified, the text 1 is removed from the clampers 7 and 7, and a completed photo book is obtained.

  Next, the operation of the gluing device having the above configuration will be described.

  By driving the motor 21, the base 8 is moved directly below the stick-like hot melt adhesive 9a. The base 8 is preheated by a heater.

  The stick-like hot melt adhesive 9a moves on the substrate 8 by driving the motor 14. As a result, the stick-like hot melt adhesive 9 a is melted and spreads as a film 9 on the substrate 8.

  On the other hand, the body 1 is clamped by the clampers 7 and 7, and the clampers 7 and 7 are moved along the horizontal guide rail 15 onto the base 8. The clampers 7 and 7 stop on the base 8, and the back of the main body 1 faces the hot melt adhesive film 9 on the base 8.

  By driving the motor 21, the base 8 and the cam 17 are moved. As a result, the main body 8 moves up and down together with the clampers 7 and 7 and the horizontal guide rail 15, and at the same time, the base 8 moves in small increments. As shown in FIGS. The agent is applied repeatedly. In this way, when the body 1 is repeatedly pressed against the base 8, the hot melt adhesive penetrates deeply from the back end surface of the body 1 into between the sheets 2 and 2.

  When gluing of the back of the main body 1 is completed, the main body 1 is transported along with the clampers 7 and 7 along the horizontal guide rail 15 to the cover attaching section.

  When the cover 4 is inserted between the spine of the main body 1 and the cover attaching portion and the cover 4 is positioned, the entire cover attaching portion is raised, and accordingly, the spine 4b of the main body 1 and the cover 4 is press plate. It is introduced into the gap between 10 and 10, and the cover 4 is bent upward.

  Subsequently, the pair of press plates 10, 10 approach and press both sides of the body 1 and the back 4 b of the cover 4. The hot platen 5 is heated by a heater, and the heat melt adhesive coating film 3 on the back of the main body 1 is melted again by this heat, and the back of the main body 1 is firmly bonded to the back 4 b of the cover 4.

  Thereafter, the press plates 10 and 10 are opened to release the body 1 to which the cover 4 is bonded, and then the cover attaching portion is lowered.

  Then, after the hot melt adhesive of the coating film 3 is solidified, the text 1 is removed from the clampers 7 and 7. Thus, the text 1 wrapped with the cover 4 is completed as a photo book.

<Embodiment 2>
As shown in FIGS. 7A to 7D, in the second embodiment, the body 1 is set at a fixed position above the base 8 and then moved toward and away from the base 8 a plurality of times, that is, moved up and down. Each time this lifting and lowering operation is repeated, the back of the main text 1 is pressed against the hot melt adhesive film 9.

  Since the body 1 is pressed into place on the base 8, the hot melt adhesive film 9 is formed thicker than in the first embodiment.

  In addition, in this Embodiment 2, the same part as Embodiment 1 is shown using the same code | symbol, and the overlapping description is abbreviate | omitted.

  In addition, this invention is not limited to the said embodiment, A various change is possible within the range of the summary of this invention. For example, although the embodiment has been described as a method and apparatus for gluing the back of the text of a photobook, the present invention is not limited to a photobook, and can be applied as a method and apparatus for gluing the text of a booklet such as a picture book or catalog. Further, the adhesive is not limited to the hot melt adhesive, and other adhesives such as water glue can also be used. The relative raising / lowering operation of the main body and the adhesive is not limited to the raising / lowering operation in the vertical direction, and may be an approaching / separating operation in the inclined direction and the horizontal direction as necessary.
