Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a paper fed in a predetermined order, which is folded in two along a center line, and glue is applied to the outside of the fold except for the final paper. The present invention relates to a saddle stitching and gluing apparatus used in a saddle stitching apparatus that performs saddle stitching by pressing a glued portion of one book.

[0002]

2. Description of the Related Art Conventionally, in the case of bookbinding by the saddle stitching method, the center line of a sheet fed in a predetermined order is folded in two along a fold, and the sheets including the final sheet are integrated into one book. The book was bound by binding with wires. Such a book bound by wire binding has drawbacks in that the ends of the wire are exposed from the paper, damaging the reader's finger, or the paper in the wire portion is broken and the paper comes off the book.

Also, a book stitched with a wire as described above cannot be recycled unless the wire is removed, and it takes more time and expense than necessary to recycle. Or was. There has been proposed a saddle stitching apparatus which can solve the drawbacks of the conventional saddle stitching method using wires and is also suitable for recycling (see Japanese Patent Application Laid-Open No. 11-301137).

In this conventional saddle stitching apparatus, cut sheets are sent out one by one in the order from the cover to the text, with the cut sheet facing down.
While applying the line glue on the center line of the cut paper with the knurl controlled by the sensor except for the final paper, the sheets are stacked until a predetermined number of single sheets are reached, and finally the center line is creased and the line glue part is folded. Is pressed to bind the book. According to the saddle stitching apparatus, since no wire is used, the above-mentioned drawbacks such as damage to the finger and detachment of the paper can be solved, and the apparatus is also suitable for recycling.

[0005]

However, the above-mentioned conventional saddle stitching apparatus has the following disadvantages. (1) When the cut paper is flat, line glue is applied to the center of the cut paper, so that when the cut paper with the line glue is bent, the center line is out of order, and there is a disadvantage that the cut paper is adhered at different portions. (2) The line glue is applied by supplying a fixed amount of glue from the nozzle in synchronization with the moving speed of the cut sheet. At this time, it is difficult to adjust the amount of glue discharged from the nozzle, and this adjustment is not appropriate. There is a disadvantage that the cut paper cannot be properly bonded and bound due to too much or too little glue. (3) High precision is required when arranging the nozzle, and there is a drawback that wire glue is applied to a different position if it is not appropriate. (4) There is a disadvantage that a device for preventing the glue from dropping from the tip of the nozzle between the cut sheets is required. (5) Since the sensor detects the leading edge of the cut sheet and discharges the glue from the nozzle to apply the line glue, when the detection surface of the sensor cannot detect the leading edge of the cut paper due to dirt or the like, the line glue is not applied, and However, there is a disadvantage that a control device for discharging the glue from the nozzle based on the detection signal is required. SUMMARY OF THE INVENTION It is an object of the present invention to provide a gluing apparatus for saddle stitching that solves the above-mentioned drawbacks and has a simple structure and that can glue reliably and accurately.

The gluing roller 11 is raised by the action of the gluing cam 35 a predetermined time before the rear end of the paper 55 reaches the lower end of the gluing roller 11. As a result, a portion where the glue is not attached is formed at a portion at a predetermined distance from both ends of the sheet 55.

The paper 55 glued in this way is
The next full-automatic high-speed saddle stitching machine 4 is moved to the next full-automatic high-speed saddle stitching machine 4, and the one sheet including the final sheet (cover) is collected in the full-automatic high-speed saddle stitching machine 4, and the glued portion of the single book is fully automatic high-speed saddle stitching Saddle stitching is performed by pressing with the machine 4.

Finally, the book which has been saddle-stitched is cut by a fully automatic three-way cutting machine 5 on all sides except for the gluing portion, to obtain a final completed book. Since the saddle stitching and gluing apparatus configured as described above operates as described above, there are the following advantages.

(1) The paper 55 is folded in two and the crease 5
6, since glue is attached to the fold 56 from the glue feeding spring wire 13 of the glue roller 11, there is an advantage that accurate gluing can be performed. (2) Since the glue adheres to the glue feed spring wire 13 and is adjusted by the glue amount adjuster 45, and the glue feed spring wire 13 comes into contact with the fold 56 of the paper 55 and adheres thereto, an appropriate Amount of glue can be attached, and paper 5
5 can be properly bonded and bound. (3) Gluing is performed while being sandwiched between the gluing roller 11 and the O-rings 53, 53.
You can always glue properly. (4) Since the glue does not fall from the glue feeding spring wire 13, a device for preventing dripping of the glue is unnecessary. (5) Since the gluing roller 11 is moved up and down mechanically, gluing can be performed reliably without any special device. It should be noted that the present invention is not limited to the above embodiment, and various modifications and changes can be made without departing from the spirit of the invention described in the claims.
