FIG. 1 is a side view showing a schematic configuration of the intermediate binding machine 10. In FIG. 1, the middle binding machine 10 is arranged adjacent to the printing machine 1, and the printed paper 3 is supplied from the printing machine 1 to the middle binding machine 10 from the ejection unit 2. Reference numeral 13 is used when the paper printed on the tray is manually supplied to the middle binding machine 10.

【0021】

Reference numerals 11 and 12 are the first and second paper feed rollers, and the paper discharged from the printing machine 1 is fed into the middle binding machine 10 by a conveyor belt 21 provided in a substantially horizontal direction. Reference numerals 13 and 14 are first and second paper accumulators provided inside the intermediate binding machine 10, and accumulating paper having different contents from the paper carried from the printing press 1 to the intermediate binding machine 10. To do. That is, the cover page is accumulated in any one of the first and second paper stacking portions 13 and 14, so that the binding process can be performed together with the paper bundle.

【0022】

Further, for example, color printing paper is accumulated in the first and second paper accumulating units 13 and 14, and inserted into a predetermined page of the paper carried in from the printing machine 1 to form a paper bundle. Can be bound. It is also possible to stack the cover sheet on one of the first and second paper stacking units 13 and 14 and the insert paper on the other side. 15 and 16 are carry-out rollers that carry out paper from the first and second paper collection units 13 and 14, and 17 are carry-out rollers 15 and 16 that carry out paper from the second paper feed roller 12 It is a transport belt that feeds to.

【0023】

The paper 3 carried from the printing machine 1 to the saddle stitch folding machine 10 and the paper (cover) supplied from the first and second paper accumulating units 13 and 14 are used for the saddle stitch folding process. The tips of the papers are aligned at the position of the stopper 18 of 1 and are sequentially laminated to form a paper bundle 22. Although not shown, the first stopper 18 is operated by a solenoid to stop a bundle of paper that is saddle-stitched and folded, but is operated so that a bundle of paper that is not saddle-stitched and folded is passed through.

【0024】

Reference numeral 19 denotes a stitcher arranged near the center of the paper bundle 22 formed at the position of the first stopper 18. The stitcher-19 moves horizontally according to the size of the paper bundle 22 to be bound, and is positioned so that the binding needle is struck near the center of the paper bundle 22. The stitcher-19 has a configuration in which a binding needle is driven from the lower side of the paper bundle 22 carried into the middle binding machine 10.

【0025】

When the saddle stitching process is completed, the first stopper 18 is opened, and the bound paper bundle 22 is conveyed in the substantially horizontal direction by the transfer belt 21 driven by the transfer roller 20. A switching gate 30a is provided on the front side of the third feed roller 29, and the paper bundle 22 whose course is selected by the switching gate 30a is driven by the transport roller 20. The belt 21 falls through a substantially vertical transport path, and its tip stops at the position of the second stopper 23. In this way, the transport belt 21 forms a substantially horizontal transport path and a substantially vertical transport path continuously at the position of the transport roller 20.

【0026】

24 is a folding knife and 25 is a pair of folding rollers, and these parts form the first folding portion A. 26 cuts and aligns the edges of the bundle of paper folded with a cutter. Since the binding needle is driven into the binding portion 19 from the lower side of the paper bundle 22 formed by aligning the tips of the papers at the positions of the first stopper-18 and sequentially stacking them, the binding portion 19 is driven in a substantially vertical direction of the transport belt 21. The paper bundle 22 that has fallen through the transport path of the paper and whose tip is stopped at the position of the second stopper 23 is arranged so that the position on the straight side of the binding needle is on the inside and the position on the bite side is on the outside. There is.

【0027】

Therefore, in the first bent portion A, the folding knife 24 is arranged on the outside of the transport path in the substantially vertical direction of the paper bundle, and the pair of folding rollers 25 are arranged on the inside thereof. The folding knife 24 is pushed in from the biting side of the binding needle driven into the paper bundle, and the paper bundle 22 is transferred to the carry-out roller 27 through the guide 26 with a folding habit by the pair of folding rollers 25. The carry-out roller 27 carries out the paper bundle 22 that has been saddle-stitched and folded to a third paper collecting unit 28 provided inside the saddle-stitching folding machine 10.

【0028】

In the third paper stacking unit 28, the paper bundles 22 are stacked in the vertical direction with the folding position on the lower side and the open side on the upper side. When the paper bundles 22 are accumulated in this way, the folded paper bundles 22 are dropped from the carry-out roller 27 and are sequentially accumulated, and the folding positions are aligned so that the folded paper bundles are accumulated without any gaps. The stacking efficiency of the paper stacking unit 28 can be improved.

【0029】

As described above, in the present invention, the first folding portion of the intermediate binding machine sandwiches the substantially vertical transport path of the paper bundle, arranges the folding knife on the outside, and arranges the folding knife on the outside, and a pair of folding rollers on the inside. Since the transport path for the folded paper bundle is formed, the size of the middle binding machine can be reduced. Further, since the stacking portion of the paper bundles that have been subjected to the saddle stitch folding process is provided in the internal space of the saddle stitch folding machine, the installation space of the saddle stitch folding machine can be effectively used.

【0030】

Paper that is not saddle stitched by Stitcher-19 passes through the first stopper-18. The paper has a switching gate 30a provided at a position in front of the third feed roller 29, which blocks the path to the first bent portion A for performing the middle folding process. The paper that has passed through the third feed roller 29 passes through the transport path 31 installed in the substantially horizontal direction, and the path is selected by the switching gates 30b and 30c and is carried into the second binding machine 40 as it is. Will be done.

【0031】

Paper that is not saddle-stitched may be folded only by the second folding portion B provided in the saddle-stitching machine 10. In the folding process by the second bending portion B, the course of the paper carried in through the transport path 31 installed in the substantially horizontal direction is changed by the switching gates 30b and 30c, and the fourth feed roller is changed. -The tip of the paper is stopped by the third stopper -33 by the la 32. Further, the rotation direction of the fourth feed roller 32 is changed to stop the other end of the paper with the fourth stopper-34.

【0032】

In this way, the paper stopped at the third and fourth stoppers-33 and 34 at both ends is pulled out again by the fourth feed roller 32, and from the fifth feed roller 35 to the second binding machine 40. Give the paper a crease when it is brought in. In some cases, the paper is carried directly from the third feed roller to the second binding machine 40 without providing the second bending portion B.

【0033】

The second binding machine 40, which is arranged adjacent to the middle binding machine 10 and connected to the middle binding machine 10, has a first transport unit 41, a second transport unit 43, a third transport unit 44, and a fourth. A transport section 45, a switching gate 42, a binding section 46, and a carry-out roller 47 are provided. Reference numeral 48 denotes a stacker for stacking paper attached to the second binding machine 40.

【0034】

The paper carried into the first transport section 41 by the switching gate 42 is guided to the second transport section 43, and the paper once transferred in the arrow P direction by the fourth transport section 45 is viewed in the opposite direction Q. The sheets are transferred in the direction, the tips are aligned at the binding portion 46, and the sheets are sequentially stacked to form a paper bundle. The paper bundle thus formed is subjected to a predetermined binding process such as flat binding and corner binding by the binding portion 46. The bundle of paper that has been bound is transported in the direction of arrow R by the fourth transport unit 45, and is carried out from the carry-out roller 47 to the stacker-48.

【0035】

The path of the paper folded by the second folding portion B of the middle binding machine 10 is selected by the switching gate 42 depending on the presence or absence of the binding process. The paper that is not bound is carried out from the carry-out roller 47 to the stacker-48 through the third transport section 44. The paper to be bound is transferred to the second transfer section 43 and the fourth transfer section 45 by the switching gate 42 as described above, and the tips of the sheets are aligned by the binding section 46 to form a paper bundle. , Performs binding processing at a predetermined position on the paper bundle.

【0036】

The second binding machine 40 to which the stacker-48 as shown in FIG. 1 is attached does not perform saddle stitching and is easy to configure. Therefore, as shown in the configuration diagram of FIG. As a binding machine for saddle stitching, it is placed adjacent to the printing machine 1 and widely used for users.

【0037】

In the present invention, focusing on the fact that the second binding machine 40 shown in FIG. 1 is widely used by users as a general-purpose machine for flat stitching and corner stitching, these binding processes are performed. The saddle stitch folding process, which is performed by the general-purpose machine and has a complicated structure of the binding processing unit and the folding processing unit, is to be performed exclusively by the saddle stitch folding machine of the present invention. For this reason, the configuration of the binding portion and the transport path of the paper bundle in the medium binding machine is simpler than that of the conventional one shown in FIG.

【0038】

Further, as described above, the space of the first bent portion can be reduced as compared with the conventional case, so even if the second binding machine 40 is connected adjacent to the saved space, the space will be reduced. It does not increase so much. When the second binding machine 40 is connected adjacent to the saddle stitching machine 10 in this way, the saddle stitching process, the flat stitching process, and the corner stitching process are performed by operating the switching gate. Since the selection can be made, the convenience during the binding process is enhanced.

【0039】

That is, when the saddle stitch folding process is not performed, the saddle stitch folding machine is removed as shown in FIG. 2, only the second binding machine 40 is connected to the printing machine 1, and when the saddle stitch folding process is performed, printing is performed. It is not necessary to remove the second binding machine 40 from the machine 1 and connect only the saddle stitch folding machine 11. The binding process can be selected while the middle binding machine 10 and the second binding machine 40 are connected, and the operability of the binding process is improved.

【0040】

In the paper stacking unit 28 provided inside the saddle stitch folding machine 10, the paper bundles that have been saddle stitched and folded are aligned and stacked in the vertical direction, but the paper bundles are sequentially arranged from bottom to top. It is also possible to stack them by arranging them in the horizontal direction.

【0041】

[Effect of the invention]

As described above, in the invention according to claim 1, a folding knife is arranged on the outside by sandwiching a second transport path formed in a substantially vertical direction of the intermediate binding machine, and a pair of folding rollers are provided on the inside. Since it is arranged, the size of the middle binding machine can be reduced and the cost can be reduced. In addition, since the first paper stacking section for accumulating the paper bundles that have been saddle-stitched and folded is provided in the internal space of the saddle-stitching machine adjacent to the pair of folding rollers, the installation space of the saddle-stitching machine is provided. Effective use of space can be achieved.

【0042】

In the invention according to claim 2, since a second paper stacking section for accumulating at least one of the cover and the insert paper to be stacked on the saddle stitched paper bundle is provided inside the saddle stitch folding machine, it is medium. The installation space of the binding machine can be used more effectively.

【0043】
