Description

[Detailed Description of the Invention] This invention provides an outer surface of a main body part that is placed in a cover wrapping machine for pasting together the contents of books, notebooks, etc., that is, the main body part and the cover, at the facing part during bookbinding. #C This relates to a gluing device.

Recently, it has become common for books, notebooks, etc. (hereinafter simply referred to as books) to have a pocket integrated with the cover, on the inside of the cover, in other words, on the endpaper, to hold business cards, address information, etc.

Conventionally, machines for automatically pasting together the main body of this type of book, the cover, and the special number ζ plastic cover were:
This machine is called a cover wrapping machine, and the rollers apply glue to both outer surfaces of the main body that is fed from below, and then it is raised further and the cover that is waiting at the top is placed over it, and the outer side of the main body and the cover are glued together. They both finished #c1 and were integrated.

However, the gluing device used in that case was for the 1ζ type without pockets as described above, so when trying to cover the cover with a pocket with that device and stick it on, the glue was applied to the entire outer surfaces of both sides of the main body. Because of this, the paper on the outside of the main body part also sticks to the pocket that is integrated with the cover, making it impossible to perform I-printing with conventional machines. The gluing of the endpapers and the wrapping and pasting of the cover were also done by hand, making it extremely inefficient.

This invention solves this problem. According to the gluing device of the present invention, the outer part Cζ of the main body of the book corresponding to one pocket part of the cover is not glued, so there is no pocket on the cover. Even if the cover does not have a pocket, if the gluing device of the conventional cover wrapping machine is improved, it will automatically glue the outside of the main body part, and then glue the cover and the book. The binding process can be performed on the main body of the book, and after it leaves the cover wrapping machine, the binding can be completed by simply inserting the non-glued endpaper into the inside of the pocket by hand. be.

Next, to explain based on the drawings, the conventional gluing device is as shown in Figs.
The main body part 1 of the book is suspended on one or more plates 2 arranged in a ξζ direction so as to pass between the gluing devices, and on both sides of the passing position there are glue tanks (m) containing glue.
and - of the axis in the window! ! r# (fixed position lζ on the 51 circumferential surface
A large roller 5 (roll) and a small roller (noto) with four shallow grooves on the entire circumference are arranged as shown in Figure 1. The glue that is
One stick on the circumference of the large roller (4) rotated in the direction of the arrow,
The glue is transferred from the surface of the large roller (41) to the small roller (6) rotating in the direction of the arrow, and then the glue is transferred to the plate (2) 1.
ζ Both outer surfaces of the main body part 10 of the book that has been supported and raised are coated with glue, and the main body part of the book that has been coated with glue on both outer surfaces rises further. The main body is then wrapped in the cover and glued together to complete the process. Here, the shallow grooves provided on the circumferential surface of the small roller (6) are for better retention of glue, and the concave grooves (5) provided on the circumferential surface of the large roller This is to supply a thick and sufficient amount of glue to the cryo-method or spine affixed part on the back of the part, and between the large roller and small roller (6) there is a 1 to have a slight gap, and the rising speed of the 1ζ plate (2),
The rotational speed of the large roller (6) and the small roller (6) are determined by applying an appropriate amount of glue on both sides of the main body, and with a concave groove (5
) They are driven in appropriate synchronization so that a larger amount of glue is supplied and applied to the cryogenic area than to other areas where Iζ is held.

With such a conventional gluing device, glue is applied to both outer faces of the main body of the book. If the parts Cζ are overlapped and glued together, there will be an inconvenience that the paper of the endpaper will also stick to the top of the pocket. On the other hand, the gluing device of the present invention moves the small roller and large roller corresponding to the pocket side -ζ of the cover to the seventh roller.
As shown in Figure 8, the net-like groove in the corresponding part of the small roller (1ζ pocket) is eliminated, and this part is brought into close contact with the large diameter part (2) of the large roller (4). , these portions Iζ are designed to prevent glue other than the glue for cold sand carried by the groove (5) from migrating to the main body of the book. As shown, the main body part (1
) is a rectangular non-glued part αe (in Fig. 7, the right side of the dashed line, in Fig. 8, a point am).
For the non-glued part (2) The diameter portions (2) are brought into close contact with each other, and for the gluing H (2), the mesh-shaped grooved portion of the small roller (6) and the small diameter portion 0 of the large roller (4) are A slight gap Rm corresponding to the thickness iζ of the glue to be supplied is created between the small diameter portion (b) and the small roller (b).

In this case, instead of making the non-glued part α0 of the book body (υ) into a rectangular shape, the book body part (υ) should have the shape of the pocket corresponding part α◆ as shown by the two-dot chain line in Figure 7.8 (A). The shape of the large diameter portion of the large roller (4) corresponding to it is made to have a similar but slightly larger shape lζ, and the shape of the large diameter portion of the corresponding large roller (4) also corresponds to the shape tC of the non-glued portion as shown in Fig. 7.8 (B). It is also possible to form a pocket-like large diameter portion 0 as shown by the dashed line in Section 7.
As shown in Fig. 8 (B) Fig. 1, the large roller ((non-glued)) has the same diameter as the large diameter f15as at the end opposite to the corresponding large diameter part (2). A diameter portion (2) is provided, which is used when the large roller (shape and small roller (6)) are brought into close contact with each other.
This is to maintain the correct parallel state of the large roller (1) and small roller (6) at all times.
) may be a movable tightening mechanism using a bolt or nut I with a spring acting in the separation direction. Furthermore, the mesh-like grooves on the circumferential surface of the small roller (6) may be completely eliminated over the entire small roller. Furthermore,
The main body part (υ is the large roller (5 from the right side in Figure 7 of 4J)
Since the end faces will be aligned with the position of the intestine as a reference, the groove (5) will start from about 5 cm from the end of the ζ as shown in the figure, and will be connected to the right end of the small diameter part α. In the case of Fig. 8, the right end of the large diameter part (to) is set as the reference position of the end face of the main body part (1), and the groove (6) extends from the right end to the small diameter part (b) and the large diameter part. 5- from the right end surface of (to)
It is better to provide a processing chain for the s position. In some cases, the groove (6) may be provided only in the small diameter portion.

Then, as shown in Fig. 7, if lζ small diameter part ■ and large diameter part (2) are provided with large roller (4) Iζ, if the size of the pocket part is almost the same, the length of the whole book will be Gluing can be done using the same roll even if the size is slightly different.
It is convenient and possible.

Next, to explain the function 1ζ of the device of the present invention, similar to the conventional device shown in FIG. ) The large roller +41 and small roller (6) on the side corresponding to the non-pocketed side of the cover are the same as before, but the large roller +41 and small roller (6) on the side corresponding to the pocket appendix lζ are the same as before. ) has a unique configuration as shown in Figure 7.8, which has already been explained, and the main body part (1
) corresponding to the non-glued part (to) Iζ of the large roller ((to) the large diameter part (to) or the pocket-like large diameter part d and the small roller (6)
Because the part without mesh-like grooves is in close contact with the small roller (6) in that part, the glue does not transfer at all except thick glue, while the large roller (6) corresponding to the gluing part does not transfer the glue at all. Since there is a gap between the small diameter part (B) and the small roller (6) in 4), an appropriate amount of glue is applied to the small roller (6) 1 in that part.
As a result, no glue is applied to the non-glued portion αe of the main body portion (1), and the glue is applied only to the glued portion α0. Here, it goes without saying that glue is applied over the entire surface of the main body part (the side lζ of the front cover of υ that does not have a pocket, opposite to the cage). Also, glue is applied to the entire surface of the main body part (υ) of the kanreisha or spine pasteboard (9). The portion Cζ will be coated with thick glue carried by the grooves (6) on both sides thereof over all or almost all of it.

In this way, the main body part (1) coated with the lake is further
This plate (2) rises with the plate (2), and the cover (η) that is waiting upwards as in the past is covered and wrapped, and the cover (■) is pasted on the outside of the main body part (1).
It is discharged from the cover wrapping machine. In addition, the cover (
7) For the book iζ that grows pockets (3) on both insides, the large rollers on both sides (both the large rollers and the small rollers (6) are 1ζ,
Of course, it is sufficient to use the unique type of large roller and small roller based on the present invention, which are different from the conventional large roller and small roller.

As described above, according to the gluing device of the present invention, the main body portion (
No glue is applied to the part of the endpaper of υ that corresponds to pocket (3) on the cover history, so that part will not stick to the pocket (3) and will not be removed from the cover (output from the printing machine). After that, if you manually insert the unglued part of the paper into the inside of the pocket (3) as described above, the endpaper part will be completed. Even if there is a book with a cover without a pocket, most of the gluing and wrapping work can be done automatically by machine, so it saves manpower, allows for mass production and improves efficiency, and is highly effective. You can play the nest.
