DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a saddle stitch book or a method and an apparatus for opening a saddle stitch immediately before binding with a staple. The present invention relates to a device for mounting in a book.

[0002]

2. Description of the Related Art As a technique for mechanically opening a book after bookbinding, a perfect binding book (a structure in which pages are bound with an adhesive, which is generally used for expensive books) uses gravity. A device for opening a page at random has been proposed.
Since this device is for inserting a postcard or a bookmark between pages of a randomly opened book, there is no problem even if the page to be opened is not specified.

On the other hand, when a postcard or the like is mechanically attached to a specific page, even a perfect binding book may be a saddle-stitch book (a structure in which paper on which pages are printed on the left and right are overlapped and bound at the center,
Generally used for cheap books), but before binding,
In general, the postcard is pasted on a predetermined page, and then bookbinding is performed.

[0004]

When the above-mentioned existing technology is used, even if a hard plate such as a compact disk (CD) or a floppy disk (FD) is to be stuck on the center page of a saddle stitch book, You can't do this. For example, the former device, which randomly opens a book after bookbinding using gravity, cannot always open the central page of the book. In addition, when the latter technique of pasting the object to a signature before binding is used, the object, that is, a CD, an FD or the like is damaged. This is because, in the bookbinding of saddle-stitched books, the printing paper serving as a book is repeatedly passed through the nip rollers and dropped onto a matching chain repeatedly. For this reason, during bookbinding,
Printing paper requires flexibility and lightness. Therefore, if a hard plate such as a CD or FD is stuck on the printing paper, not only does it hinder the bookbinding operation, but also the CD or FD.
And the like.

[0005] Therefore, as described above, a request for sticking a hard plate-like body to a saddle stitch book has to be manually dealt with at present.

[0006] The present invention has been made in view of the problems of the related art, and has as its object to provide a method and apparatus for mechanically opening a center page of a saddle-stitched book.

[0007]

According to the method of opening a saddle-stitched book or signature of the present invention which achieves the above object, the book or signature is conveyed in a closed state, during which the book or signature is opened. By gradually reducing the distance between the first and second members abutting the side and back of the end, and applying a compressive force in the horizontal direction to the book or signature, the half above the center of the book or signature. Raise the body, create a gap between the other half, and then insert the lower end of the opening guide that gradually and diagonally upward in the transport direction into this gap, The upper half is gradually lifted along the opening guide.

[0008]

When the saddle stitched book or signature is transported, the distance between the first and second members is reduced, and when a compressive force in the horizontal direction is applied, the upper half of the central page is structurally higher. Rising. For this reason, a gap is created between the other half, and an opening for inserting the lower end of the opening guide is formed here. Since the opening guide gradually extends obliquely upward, the upper half is gradually and automatically lifted as it is transported, and the book or signature is opened.

[0009]

1 to 3 are a plan view, a front view, and a side view schematically showing a CD sticking apparatus to which a method and an apparatus for opening a saddle stitch book or signature according to the present invention are applied. .

[0010] The apparatus of the present embodiment is an A4 or B
It is designed to attach a bag P containing a CD to a 5-size saddle stitch book. The saddle stitched book and the CD storage bag after bookbinding are introduced into the apparatus from the feeder 10 and the feeder 40, respectively. The apparatus of this embodiment will be described below along the processing operation flow.
An example will be given for a book of a size.

The feeder 10 of the saddle stitch book A4 after bookbinding is
A conveyor 14 for loading books is provided. The book A4 is supplied onto the conveyor 14 by the conveyor 12, and is positioned on the conveyor 14 by the stopper 16. Above the conveyor 14, a vacuum pad 18 connected to a vacuum pump (not shown) and operable in a manner indicated by an arrow C1 in FIG. 2 is provided. That is, the pad 18 is
Are sucked one by one and conveyed to the nip roller 22, where the book is caught by the roller 22 and released to return to the initial position.

At the exit of the nip roller 22, one end of a belt conveyor 24 is disposed, and a holding belt 26 and an opening belt 28 are disposed adjacent to the one end. The holding belt 26 and the opening belt 28 have an endless belt structure wound around driven rollers, and are driven by the contacting articles. An opening guide 32 and a back guide 36 attached to a supporter 34 along the conveyor 24.
Is arranged. The center page of the book A4 is opened by the opening guide 32 as the book A4 is conveyed along the conveyor 24 in the direction C2 in FIG. The details of the embodiment are as follows. During processing of A4 size books, it is desirable that the B5 size pressing belt 26a be lifted so as not to contact the books.

On the conveyor 24, the holding belt 2
6 rotates in a state in which the side of the open end of the book A4 is pressed against, and the opening belt 28 rotates in a state in which it contacts the back of the book A4.

At the entrance side of the conveyor 24, FIG.
That is, as shown in the cross-sectional view of the main part along the line IVA-IVA in FIG. 1, the book A4 is not subjected to a compressive force in the horizontal direction, and therefore, the book A4 is in a normal closed state.

However, since the opening belt 28 is gradually tapered toward the center of the conveyor 24, the distance between the opening belt 28 and the holding belt 26 is gradually shortened, and a compressive force is applied to the book A4 in the horizontal direction. Is done. Therefore, the upper half of the book A4 rises, and a gap is generated between the upper half and the lower half, that is, between the center pages and near the back. Then, the opening guide 32 enters this opening, and FIG.
(B) That is, the state is as shown in the cross-sectional view of the main part along the line IVB-IVB in FIG.

Subsequently, since the guide 32 extends obliquely upward, the upper half of the book A4 is gradually lifted as the book A4 is fed by the conveyor 24. As a result, in the book A4, the center page is opened, and the upper half is leaning against the back guide 36. This state is shown in FIG. 4C, that is, a cross-sectional view of a main part along the line IVC-IVC in FIG.

The other end of the conveyor 24 has a conveyor 24
A conveyor 54 for transporting the book A4 in a direction perpendicular to the direction A is provided. The opened book A4 is positioned on the conveyor 54 by the guides 32 and 36a and the movable stopper 38. The stopper 38 can be mechanically adjusted so as to lock the book at an optimum position according to the size of the book. For example, when processing a book of B5 size, the stopper 38 is moved somewhat toward the conveyor 24 side.

The feeder 40 for supplying the bag P containing the CD can also be mechanically adjusted in accordance with the size of the book or the position where the bag P is attached. For example, when processing a book of B5 size, the feeder 40 is also moved somewhat toward the conveyor 24 side.

The feeder 40 is provided with a vacuum pad 42 connected to a vacuum pump (not shown) and operable in a manner indicated by an arrow C3 in FIG. A nip roller 44 is provided at an outlet of the feeder 40.
Like the pad 18, the pad 42 sucks the bags P one by one and transports them to the nip roller 44. After the bags are caught by the rollers 44, they are released and returned to the initial position.

The nip roller 44 also functions as a gluing roller, and applies an adhesive for attaching the bag P to the book A4 on the back surface of the bag P. Accordingly, a member (not shown) for appropriately replenishing the adhesive is engaged with the roller 44.

At the exit of the roller 44, a conveyor 46 is provided. The conveyor 46 is disposed so as to be inclined downward, and a guide 48 is attached to the tip thereof. The conveyor 46 and the guide 48 are formed so that the contact area with the bag is reduced so that the bag P is not moored by the adhesive.

A stopper 52 is provided to face the guide 48. The stopper 52 penetrates into the opened book A4, and is arranged such that the tip of the bag P dropped from the guide 48 abuts. The conveyor 54 is set so that the tip of the bag P abuts against the stopper 52 and starts after being placed on the opened book A4.

When the conveyor 54 is started, the book A4 is put in the bag P
Are transported in the direction of arrow C4 in FIG. Book A
4 is closed at the top which is opened when passing through the slit 36b below the guide 36a, and further, two pairs of nip rollers 56,
It is bitten by 58. The book A4 receives pressure while passing between the rollers 56 and 58, whereby the bag P is firmly adhered to the book A4.

The outlet of the roller 58 has a product stocker 60
Is arranged. The stocker 60 includes four pairs of opposing forks 66 reciprocated by a cylinder 64, and the book A <b> 4 discharged from the rollers 58 is temporarily placed on the forks 66. The stocker 60 also includes a stopper 62, and the book A4 is positioned on the fork 66 by the stopper 62.

A conveyor 68 is provided below the fork 66. The conveyor 68 is rotatable in a horizontal plane,
The direction of the book A4 stacked on the conveyor 68 can be changed every predetermined number of copies. That is, when a predetermined number of books are accumulated on the fork 66 in the state shown in FIG. 3, the fork 66 is opened and the same number of books are stacked on the conveyor 68. Next, when the conveyer 68 rotates 180 degrees in the horizontal plane and a predetermined number of books accumulate on the fork 66 again, the fork 66 is opened, and the same number of copies Books are loaded. The book A4 stacked on the conveyor 68 is discharged out of the system by the conveyor 68 and the conveyor 72 after the conveyor 68 is full.

The saddle stitch book A4 processed by the above-described apparatus.
Is in a completed state as shown in FIG. The bag P containing the CD is attached to one of the center pages of the book A4. Bag P
Can be appropriately changed by adjusting the position of the stopper 38 or the feeder 40. S in FIG. 5 indicates a stapler needle that closes the saddle stitch book.

In the above embodiment, the saddle stitch book A4
Has been described in the mode of processing after binding with the staple S,
The above embodiment is similarly applicable to a signature immediately before binding with the staple S. Further, the object to be adhered is not limited to a CD, and other hard plate-like bodies such as an FD can be used.
