Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a bookbinding method and a bookbinding apparatus for a saddle-stitched book in which a large number of four-page papers are stacked and folded.

Conventionally, wire saddle stitch binding and adhesive saddle stitch binding have been implemented as saddle stitch binding methods.

Wire saddle binding is widely used for weekly magazines and the like, and is a method in which four pages of paper are stacked and bound in the center with a wire 12, as in the book 10 shown in FIG. The wire saddle-stitched book made in this way has the central pages spread out, so when you stroke your throat strongly with your fingers, your fingertips are easily damaged by the wire 12, and if you use it for a long time, the four central pages will fall off. There is an inconvenience that the wire 12 may become rusty if the wire is removed.

Glued saddle binding is widely used for pamphlets and the like, and as in the book 20 shown in FIG. 2, glue 24 is attached to the center of a sheet of paper 22 (A), Fold it so that it overlaps and apply glue 26 again to the center (B), fold this glue 26 so that it overlaps (C), then fold this glued part as a crease (D), cut out the top and bottom and complete. This is method (E). Although the adhesive saddle-stitched book produced in this manner eliminates the above-mentioned disadvantages of the wire saddle-stitched book, it has the following limitations. In other words, a self-adhesive saddle-stitched book is not limited to the 16-page one shown, but can have various numbers of pages depending on how the paper is folded, but due to the folding process, it is not possible to make a thick book, and the maximum number of pages is limited. (However, it is about 36 pages. Also, of course, the paper quality of each page is the same.

The present invention was devised for the purpose of eliminating the disadvantages and limitations of trigger saddle stitch binding and adhesive saddle stitch binding, and allows for single-lube saddle stitch books of any number of pages and various paper types to be produced. It is to be bound into a book.

That is, the method for binding saddle-stitched books of the present invention applies glue to the outer surface of the back of the bound material that is folded at the back and has a dogleg shape, and then attaches other similarly folded binding material to the outside of the bound material. This method is characterized by repeating this process and gluing together a large number of binding materials to complete the book.

This bookbinding method will be explained in detail below with reference to FIG.

First, prepare the bound material 3o, fold it at the back to make a dogleg shape, and apply glue 22f to the outer surface of the back (A
). This bound material 3° may be a single sheet of paper with 4 pages, or it may be a glued saddle-stitched book of several 10 pages made by the above-mentioned conventional glued saddle-stitch binding. Also glue 3
2 may be attached to the entire back of the bookbinding material 30, or may be attached only to a portion or intermittently in dots. Next, to the bound material 3o glued in this way, another similarly folded bound material 3
0' and apply glue 32 to the back of this bound material 30' (B). Next, stack the binding materials again in the same way and glue them C), and repeat this process. In this way, a large number of binding materials are glued together to complete the saddle-stitched book 34.

In this bookbinding method, since a book is formed by stacking the binding materials 3o one after another, it is possible to bind a book with a large number of pages or a book in which the paper quality of each page is different. Of course, since wire is not used, there are no problems such as rusting of wire saddle-stitched books.

This bookbinding method can be easily carried out using the bookbinding apparatus of the present invention.

The binding device for saddle-stitched books of the present invention includes a conveyor for loading and transporting bookbinding materials folded at the back and having a dogleg shape in cross section, and a conveyor provided along this conveyor for stacking bookbinding materials kiffi on this conveyor. This apparatus is characterized by having a bookbinding material supply device and a gluing device that is installed between the binding material supplying devices of υ and that allows the binding material to be attached to the upper end of the bookbound material that is transferred by a conveyor clasp.

A bookbinding apparatus 40 according to an embodiment of the present invention shown in FIG. 4 will be described below. 42 is a conveyor, and a dogleg-shaped strip 44' (not shown in the drawing) extends horizontally.
t'' is attached, and a protruding piece 46 is provided on a part of this strip 44 that protrudes in the opposite direction. Therefore, this conveyor 42 is folded at the back and binds the bound material 48, which has a doglegged cross section, into a branch shape. 50.52tj: Bookbinding material supply device, which is provided along the conveyor 42 and moves the protrusions 46 in synchronization with the conveyor 42. Just before, 48 tons of bound materials were dropped.
The bound materials 48 are piled up on the conveyor 42. The bookbinding material supplying device 50 stacks the bookbinding materials 48 in a folded state in its hopper 54, takes them out one by one from the bottom end, opens the bottom part in a dogleg shape, and drops them. Bookbinding material supply device 5
2 stacks the bound materials 48 completely flat in the hopper 56, takes them out one by one from the bottom edge, and discharges them obliquely downward while folding them, and is mainly used for relatively thick papers such as covers. Reference numeral 58 denotes a gluing device, which is provided between each bookbinding material supply device 50 and 52, and is connected to the conveyor 42 and the same A.
The nozzle that spews out glue then sprays the glue onto the upper end of the bound material 48 being transferred on the conveyor 42, that is, the back of the uppermost bound material. Note that the gluing device is not limited to this type, and may be of a similar type, such as one using a gluing roller. Reference numeral 60 denotes a presser device, which is provided at the tip of the bookbinding supply device at the rear end, synchronizes with the conveyor 42, descends onto the stacked bookbinding materials 48, moves together with the conveyor 42 for a certain period of time, and presses and glues the bookbinding materials. Glue the R parts with . Note that this holding device is not limited to this type, but any other type can be used, and 1d is also the same as the position 1 in this example.
- 1 or between each bookbinding material supply device 50, or in the book kit loading process following this bookbinding device 40.
In the case of 4) where sufficient bonding pressure is applied to the 1' portion, this j.) (equipment j3 f can also be omitted.

In other words, the configuration of this bookbinding device 40 is such that a gluing device is added to the existing wire saddle stitching device, and the wire binding device (...) is removed from the presser wire binding device in this bookbinding device. be.

This bookbinding device 6': 40 operates as follows. In front of the projecting piece 46 of the conveyor 42, a first bookbinding material is placed in a gap passing under the lower part of the first bookbinding material supply device 50,
Next, use the glue device 58 to apply 4i'J) ("

Next, a second bound material is superimposed on this piece as it passes through the lower part of the second bound precious material supply device j4.50, and then the back of this second bound material is pasted by the gluing device 58. is glued to. In this way, each bound material supply device 50.
As they pass through the lower part of the booklet 52, the bookbinding materials 48 are successively glued and stacked one on top of the other. In this way, all manufacturing essences t
1 are stacked on top of each other, they are pressed down by a presser device 6o to be completely adhered, and the bookbinding is completed.

The bookbinding apparatus of the present invention can realize the bookbinding method of the present invention as described above, and is easy to implement since it requires only slight modifications to the conventional trigger saddle stitch bookbinding apparatus. can do.

As described above, according to the bookbinding method and device of the present invention, it is possible to break the limitations of conventional glued saddle stitch binding, and to produce a large number of pages and many types of paper, which was previously only possible with wire saddle stitch binding. By gluing the saddle-stitched book of the structure, it can be realized while eliminating the inconvenience of using wire.
