DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a binder for gluing a cover and a body at the time of bookbinding of a bookbinding apparatus called a binder.
The present invention relates to a gluing method using an inder .

[0002]

2. Description of the Related Art In a notebook or the like, the main body and the cover are bonded not only to the back but also to the back, but in this case, it is preferable to bond the back to the entire surface in terms of strength and appearance. The facing and the back are glued separately because the type of glue used is different, but the facing gluing is performed by applying a gluing roller to the front cover that is continuously transported by the transport device. with a glue with only frequency (dial portion when combined with text), than is adhered together with this has been transported by another transport device body. Then, Installing conventional glue, to form parallel grooves or spiral grooves in the affixed stamp on the surface of only sizing <br/> rollers, reservoir glue into the recess of the groove, which is pressed against the cover Had transferred the glue.

[0003]

According to such a method, the gluing roller and the cover must be pressed against each other with a strong force. When it is deformed (curled) and is aligned with the text, a positional shift may occur. In addition, the glue accumulated in the concave portion of the groove is uniformly transferred to the paper with the rotation of the gluing roller and is sent to the non-contact portion in order without going, and finally a large amount of glue is transferred at a time. In some cases, gluing was uneven. Further, when the glue is accumulated in the concave portion, there is a disadvantage that the amount of the glue to be transferred is too large and the paper is deformed. SUMMARY OF THE INVENTION The present invention addresses such a problem, and the point is that glue is applied to the surface of the convex and concave portions and the paste is transferred to the cover.

[0004]

SUMMARY OF THE INVENTION In order to solve the above problems, the present invention is directed to a case (1) of a cover (10) to be transferred.
A gluing roller (34) is applied to the part to be matched with the face of 2)
In a gluing method using a binder for applying glue by a binder, an uneven portion (39) is provided on the surface of a stamp (38) attached to the surface of the gluing roller (34), and the uneven portion (39) is provided. ) only the surface of the projecting portion (39a) to adhere the glue of, by the glue gluing only formed by transferring the frequency binder of the stamp (the Te than the cover in a manner adhering to 38) (10) This provides a gluing method .

[0005]

[Advantage] By taking the above measures, the adhesive applied to the projections of the irregularities on the stamp surface is transferred only by lightly contacting the paper. It is transcribed uniformly. Therefore, Stan
Depending on the shape of the concave and convex portions of the tape, it is also possible to apply the paste in a polka dot pattern to a predetermined paste area of the cover , which is the most suitable paste application form.

FIG. 2 is an explanatory view of a binder for binding a book by pasting and adhering a cover 10 and a main body 12, and FIG. 3 is an explanatory view of a main part of the same. And a bonding device 18 for applying a glue to a predetermined gluing area (a portion to be matched with the return of the text 12) and a bonding device 18 for bonding the cover 10 and the back of the text 12.

The supply device 14 has a magazine 22 for storing the cover 10 over the supply drum 20, and a sucker 24 which swings and sucks the cover 10 in the magazine 22 one by one from below. And a pull-out roller 26 that presses the cover 10 sucked by the suction cup 24 on the supply drum 20 by oscillating motion. Thus, the cover 10 sucked by the suction cup 24 is transferred on the guide plate 28 by the rotation of the supply drum 20, and is sent to the gluing device 16 by the pair of upper and lower delivery rollers 30.

[0008] A gluing device 1 for gluing a predetermined gluing area of the cover 10, that is, a counterfeit when combined with the text 12.
Reference numeral 6 denotes a transport belt 32, a gluing roller 34 and a pressing roller 36 provided above and below the transport belt 32, and the like. A stamp 38 is attached to the surface of the gluing roller 34, and the glue is supplied to the stamp 38 from a glue supply roller 40 provided above the gluing roller 34. As a result, if the pressing roller 36 is pushed up while the cover 10 is passing under the gluing roller 34, the glue of the stamp 38 is transferred to the cover 10. In addition,
At this time, the glue is applied to the entire surface except for the portion corresponding to the back when the body 12 of the cover 10 is put together. For this reason, the stamp 38 escapes the middle part corresponding to the spine of the text 12,
The size is almost equal to the size of the cover 10. Further, the cover 10 is supplied from the supply device 14 and the stamp 38 is supplied.
Synchronize with the rotation of, so that the position is always matched.
In addition, a vacuum box 42 is provided below the transport belt 32 so that the cover 10 transported thereon is transported smoothly along the cover.

FIGS. 4 to 6 are development views of the stamp 38. The stamp 38 has a convex portion 39a and a concave portion 39b on its surface.
The concave / convex portion 39 is formed, and the specific shape of the concave / convex portion 39 is such that a cylindrical projection is projected on the surface to be a convex portion 39a (FIG. 4). The protrusions and grooves are alternately formed to form the uneven portions 39 (FIG. 5), and the ridges and grooves are spiral (inclined with respect to the cover transport direction) (FIG. 6). And so on. In the case of the protrusion 39a of the cylindrical projection, the glue applied with the protrusion 39a has a polka dot pattern, and in the case of the protrusion and the groove, the glue has a streak shape.

FIG. 1 is a sectional view showing a glued state of a stamp 38 having a cylindrical projection formed as a projection 39a.
The glue is applied to the surface of the cylindrical projection by the glue supply roller 40. If the pressing roller 36 is pushed up when the cover 10 passes, this glue is transferred to a predetermined gluing area of the cover 10 in a polka dot pattern. When the polka-dot-shaped glue is adhered to the back of the text 12, the size of the cylindrical protrusion is set so that it spreads over the entire surface with a predetermined thickness.
The density and the amount of glue are set. By the way, regarding the transport belt 32 at this time, the transport belt 32 has a large number of grooves 44 formed at right angles to the traveling direction, and a through hole 46 communicating with the vacuum box 42 is formed in a valley portion thereof.
Is formed. Thereby, the groove 44 is formed on the upper cover 10.
And the side plates 48 on both sides provide a closed space, so that a wide area can be vacuumed and the suction effect is high.

The bonding device 18 for bonding the back of the cover 10 to the back of the body 12 includes a transport chain 50, a pressing roller 52, and the like. The cover 10 on the transport belt 32 is received by the transport chain 50, and is synchronized with the transport chain 50. The back of the body 12 sandwiched between the vice 54 rotating on the transport chain 50 is aligned with the back. The back of the body 12 is a cutting device (not shown) provided at another station on the upper side of the vise 54.
And a hot-melt (hot-melt) glue is attached by a gluing device 55 (see FIG. 7).
When this is combined with the cover 10, this portion is adhered when passing over the pressing roller 52. Note that the start end of the transfer chain 50 and the end of the transfer belt 32 intersect (the transfer chain 50 is stretched outside the transfer belt 32), and the transfer chain 50 has a hook 56, The cover 10 sent by the conveyor belt 32 is hooked by the hook 56 so that the conveyor chain 50 can reliably receive the cover. A transfer chain 58 is also provided below the transfer chain 50, and the back portion is the bonding device 18.
The back cover 10 and the main body 12 adhered in this manner are back-adhered in the process following the transfer chain 58.

FIG. 7 is an explanatory view showing this facing-back bonding. First, the cover 10 and the main body 12 with their backs bonded are passed through a molding machine 62 composed of a press 60 while the facing-back ends are bonded and fastened. Then, it is temporarily tightened by passing through a temporary tightening machine 68 composed of a main belt 64 and a sub-belt 66, and finally is finally tightened by a final tightening machine 72 composed of a press 70 to finish.

[0013]

As described above, according to the present invention, an uneven portion is formed on the surface of the stamp attached to the surface of the gluing roller, and the convex portion is glued to form a predetermined gluing area on the cover. The adhesive is transferred only by lightly contacting the stamp with the cover, so that unnecessary pressure is not applied to the paper, and the paper is unlikely to curl. In addition, since the glue applied in this manner can be spread in an optimum amount when matched with the text of the text, it is difficult to cause excessive glue or unevenness, and there is no waste of glue. . In particular,
When glue is applied in a polka dot pattern, the glue will be discontinuous and distributed at a uniform density, so the curl of the cover will be reduced while it is being fed on the conveyor belt or chain, and Has a positive effect on positioning and gluing,
Clean the finish. In particular, since the counter-adhesion is performed after the back, the time for conveying the sheet with the glue applied is long, and this effect is significant.
