[0004]
FIG. 3 is a schematic configuration diagram illustrating an example of performing the perfect binding process by the bookbinding machine. In the figure, 7 is a sheet called “play sheet play” on the lower side (hereinafter abbreviated as “play sheet”), 8 is an upper play sheet, and the upper play sheet 8 is a sheet stacking unit in the direction of arrow F. 3 is conveyed. After that, the sheet bundle 1 for one book is conveyed to the sheet stacking unit 3 in the direction of arrow A and stacked on the upper idle paper 8, and then the lower idle sheet 7 is conveyed in the direction of arrow E and Overlaid on a stack of paper. Here, the terms “upper side” and “lower side” are used differently depending on whether they are on the upper side or the lower side of a bundle of sheets for a book with the cover as a reference. This idle paper is a plain color paper, and there may be a case where only the upper or lower idle paper is used.
[0005]
The sheet bundle 1 for one book in which the lower play paper 7 and the upper play paper 8 are stacked is then carried into the bookbinding machine in the direction of arrow G. The bookbinding machine includes a bookbinding processing start unit 9, a milling processing unit 10, a gluing processing unit 11, and a cover attaching processing unit 12. The sheet bundle 1 for one book is transferred in the direction of arrow H in the bookbinding machine. When the bookbinding process is started, the back side of the sheet bundle 1 for one book is arranged on the level plate 9a side of the bookbinding process starting unit 9, and is sandwiched by a clamper (not shown) and sent to the milling processing unit 10 in the next process. .
[0006]
The milling processing unit 10 is provided with a milling cutter, and when passing a stack of one stack of play sheets on the upper and lower sides, the back surface is made flush with the glue on the entire surface. Pre-processing is performed so as to adhere evenly. Next, the sheet bundle for the one book whose back surface is flush with each other is sent to the gluing processing unit 11. The gluing processing unit 11 is provided with a gluing roller 11b that stores gluing in a gluing tank 11a, and performs a predetermined gluing process.

After being stuck on the back of the sheet bundle 1 on which the lower play sheet 7 is stacked, the nip plates 12a, 12b, and the bottom plate 12c, move the nip plates 12a, 12b, The vicinity of the edge of the back side of the sheet bundle 1 is tightened from both sides to fold the cover 2 and attach the cover.
[0008]
FIG. 4 is a perspective view showing another example of the bookbinding process. In the example of FIG. 4, instead of stacking the lower and upper idle sheets 7 and 8 on the sheet bundle 1 in FIG. 3, a sheet larger than the sheet bundle is made larger than the sheet bundle. The folded sheet 13 is folded and bound between the cover 2 and the sheet bundle 1 for one book.
[0009]
[Problems to be solved by the invention]
When a bookbinding process is performed by a sheet binding machine as shown in FIG. 2 or a bookbinding machine as shown in FIG. 3, if a bundle of sheets is printed in monochrome and a cover is printed in color A bundle of sheets and a cover for one book are created by separate printing machines or copying machines. For this reason, a bundle of sheets and a cover for one book are transported separately to a sheet stacking unit, and bookbinding is performed by superimposing them manually. For this reason, there has been a problem that the bookbinding process takes time due to poor work efficiency.
[0010]
In addition, as shown in FIG. 3, even when the upper and lower idle sheets are inserted between a bundle of sheets and a cover, the idle sheets are colored plain sheets. Therefore, it is created separately from a bundle of sheets for one book, transported to a sheet stacking unit, and bookbinding is performed by superimposing them manually. Furthermore, even when the folding sheet shown in FIG. 4 is inserted between a bundle of sheets and a cover, the bundle of sheets and the folded sheet are conveyed separately to the sheet stacking unit. The bookbinding process is performed by superimposing them manually. For this reason, there has been a problem that the bookbinding process takes time due to poor work efficiency.
[0011]
In view of the above problems, the present invention is a bookbinding processing device that automatically superimposes a stack of sheets such as a cover sheet for color printing, play sheets, and folding sheets, and a bundle of sheets for one booklet, thereby quickly performing a bookbinding process. The purpose is to provide.
[0012]

[0014]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of a bookbinding apparatus according to the present invention will be described with reference to FIG. FIG. 1 is a schematic side view of a bookbinding apparatus according to an embodiment of the present invention. The same reference numerals are given to the same or corresponding parts as in FIG. 2, and detailed description is omitted to avoid duplication. In FIG. 1, 14 is a supply device for a bundle of sheets 1 for one book, 15 is a collating machine, and 17 is a saddle stitching machine. A sheet bundle 1 for one book created by a printing machine or a copying machine is carried into the supply device 14. A bundle of sheets 1 collated by a collating machine installed elsewhere may be carried in.
[0015]
The collator 15 is provided with eight paper feed stages 15a to 15h in the vertical direction. Further, a horizontal conveyance path 16a and a vertical conveyance path 16b are provided. In each of the paper feed stages 15a to 15h, alignment sheets to be stacked on a bundle of sheets such as a front cover for color printing, idle paper for upper and lower sides, and folding paper are stored. These alignment sheets are fed from the vertical conveyance path 16b and conveyed to the stacking unit 3 of the saddle stitching machine 17 through the horizontal conveyance path 16a. Although not shown in the drawing, a carry-out mechanism for automatically carrying out a bundle of sheets 1 from the supply device 14 to the horizontal conveyance path 16a of the collator 15 is provided.
[0016]
Next, a specific example of the bookbinding process will be described with reference to FIG. In the example of FIG. 2, it is assumed that the sheet bundle 1 for one book is printed in monochrome, and the cover 2 is printed in color. The color-printed cover sheet 2 is carried into an appropriate paper feed stage of the collator, for example, a paper feed stage 15h. A bundle of sheets 1 is unloaded from the supply device 14 and loaded into a horizontal conveyance path 16a of the collating machine. At this time, the cover sheet 2 color-printed from the paper feed stage 15h is fed to the upper side of the sheet bundle 1 for one book through the vertical conveyance path 16b, and the sheet bundle 1 for one book is fed from the conveyance path 16a in the horizontal direction. The cover 2 printed in color is superimposed on the sheet and discharged.
[0017]
The sheet bundle 1 and the color-printed cover 2 discharged from the horizontal conveyance path 16a of the collating machine 15 are subsequently conveyed to the sheet stacking unit 3 of the saddle stitching machine 17 and described above. In this way, the finished product 6 is obtained by performing the saddle stitching process and the middle folding process. Originally, a collating machine supplies printed paper to a plurality of paper feed stages for each page, takes out the paper one by one from each paper feed stage, aligns the pages in order, and feeds the paper. Although used as a means for forming a bundle, in the present invention, focusing on the sheet feeding function of such a collating machine, the bookbinding process is performed by feeding sheets according to one sheet bundle. A collating machine is used for superimposing for the purpose of expanding the range of use of the collating machine.
[0018]
In the above example, an example in which a color-printed cover sheet is supplied using one sheet feeding stage of the collating machine has been described. However, a cover sheet is supplied in advance to a plurality of sheet feeding stages, and one sheet feeding stage is provided. When the cover feed from the paper tray is completed, the cover shifts to the next paper feed tray, feeds the cover, and stacks one paper stack and the color printed cover one after the other in order to form the saddle stitcher. It is also possible to adopt a configuration in which a large number of bookbinding processes are performed continuously by discharging to the stacking unit. When the cover is made of thick paper, there is a limit to the number of sheets that can be stored in a single paper feed stage. Therefore, such a divisional arrangement into a plurality of paper feed stages is effective.
[0019]
Next, in the example shown in FIG. 3, a single sheet bundle is printed in monochrome, the cover is printed in color, and the upper and lower colored plain idle sheets are placed between the sheet bundle and the cover. An example of bookbinding processing according to the present invention in the case of insertion will be described. In this case, for example, a color-printed cover is supplied to the paper feed stage 15f of the collating machine 15, the upper idle paper is supplied to the paper feed stage 15g, and the lower idle paper is supplied to the paper feed stage 15h. .
[0020]
When the bookbinding process is performed, the lower idle paper is first fed from the paper feed stage 15h via the vertical conveyance path 16a and conveyed to the paper stacking unit for bookbinding. Next, the sheet bundle 1 for one book is carried into the horizontal conveyance path 16 a of the collator 15. Subsequently, the upper idle paper is discharged from the paper feed stage 15g, and the color-printed cover sheet is discharged from the paper feed stage 15f, and the upper idle paper is stacked with the cover facing up, and then conveyed in the horizontal direction from the vertical conveyance path 16b. The sheet is fed onto the sheet bundle 1 for one book transported on the path 16a. In this way, the upper idle paper fed from the paper feed stage and the cover are stacked on the sheet bundle 1 for one book, and are discharged from the collator 15.
[0021]
The bundle of sheets, the upper idle paper, and the cover discharged from the collating machine 15 are subsequently conveyed to the bookbinding processing paper stacking unit in which the lower idle paper is in a bookbinding standby state. Are overlapped and bound. The bookbinding process in this case is performed by a sheet binding machine.
[0022]
Also in this example, each paper feed stage of the collating machine 15 can be appropriately sorted and used. For example, a color-printed cover sheet is supplied to the paper feed stages 15a and 15b, upper idle paper is supplied to the paper feed stages 15c and 15d, and lower idle paper is supplied to the paper feed stages 15e and 15f. Each of the alignment sheets can be continuously fed from the vertical conveyance path 16b and automatically stacked on a bundle of sheets for one book to continuously perform a large number of bookbinding processes.
[0023]
The bookbinding process by the bookbinding machine is performed as follows. The cover sheet and upper and lower idle sheets are supplied to the sheet feeding stage of the collator, and the upper and lower idle sheets are fed from the collator and overlapped with a bundle of sheets. And carry out the process up to the gluing process. The cover sheet fed from the collating machine is transported to the cover stacking unit through another transport path, and is bound and bound by the cover sheet processing unit with the sheet bundle for which the pasting process is performed.
[0024]
As shown in FIG. 4, even when folding paper is inserted between a bundle of sheets and a cover sheet, only the folded paper or both the folded paper and the cover sheet are fed from the sheet feeding stage of the collator. The bookbinding process can be performed by continuously feeding the sheets and automatically superimposing them on a sheet bundle.
[0025]
In the example of FIG. 1, only one collating machine is used, but a large number of sheets can be stored by using a multiple collating machine. For example, when four collating machines having eight paper feed stages in the vertical direction are connected and used, 32 paper feed stages can be used. As a result, the supply capacity of the aligned sheets is increased, and a large amount of bookbinding processing can be performed continuously.
[0026]
【The invention's effect】
As described above, in the present invention, since the alignment sheets are automatically fed from the sheet feeding stage of the collating machine and stacked on one sheet bundle, a large number of bookbinding processes are continuously performed. This improves the work efficiency of the bookbinding process. Moreover, since the range of use of the collating machine can be expanded, production facilities can be used effectively.
