Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides the following advantages when processing outward-folded signatures such as sutra folds using a bookbinding machine (saddle stitching, flat binding, perfect binding) or a collating and pasting machine. Simple binding for in-line processing machines in printing machines in which cutters for making cuts in the folded signatures on the outside are attached to the cutters of the opposing cutter cylinders of the rotary cutter section so that the folded pieces of the signatures do not separate. It is related to the device.

Conventionally, folded copies of rotary presses or signatures folded on the inside are processed using bookbinding machines (saddle stitching, flat binding, perfect binding machines), or collating and pasting machines. In some cases, even if the folds are suctioned by a vacuum cleaner etc., the folds will not become separated.
For signatures that are folded outwards, such as sutra folds, modified Z-folds, and three-folds, the folds are pulled one by one by the feeder, breaking them apart, and even if they are handled during the saddle stitching process, This may cause problems such as the paper being opened by the bookbinding machine (saddle stitching,
It was not possible to use a flat binding machine, a perfect binding machine), or a collating and pasting machine.

The present invention has been made to solve these problems.

The present invention will be explained with reference to the drawings which are embodiments thereof.

First, let's talk about the inline processing machines. From the rotary printing machine section A to the gluing, punching, and sewing machine processing section B, the first folding machine section C ₁ , the second folding machine section C ₂ , and the third folding machine section
The paper flow conveyed through _C3 is cut at the rotary cutter section D.

Then, as in the present invention, the folds are sent to the transfer device section E as folds in the form of outward folds, such as the sutra fold as shown in FIG.

In the present invention, the rotary cutter section D has the following configuration so that the folded sections are not separated in the transfer device section E or during the subsequent bookbinding process.

That is, in front of the opposing cutter barrels 1 and 2, there are a guide plate 5 for guiding the signatures and a drive roller 3.
and a pressure roller 4, and at the rear there are belts 6 ₁ and 6 ₂ for transporting the signatures.

On the outer periphery of the cutter barrels 1 and 2, a conventional cutter stand ₇₁ is provided in the generatrix direction, and therefore the cutter 8 is also provided on the cutter stand ₇₁ in the same direction.

On both sides of this cutter stand ₇₁ , cutter stands ₇₂ , ₇₂ are newly provided in the generatrix direction, and on these cutter stands ₇₂ , ₇₂ , a plurality of cutters 9 and 10 are lined up in the generatrix direction, and several sets of such a plurality of sheets are lined up in the generatrix direction. The cutters 8 act to cut the signature when they mesh with each other, the cutter 9 has a convex shape, and the cutter 10 has a concave shape, and functions to cut into the signature when they mesh with each other.

The signatures transferred to the rotary cutter section D having such a configuration are sent by the driving roller 3 and pressure roller 4 to the opposing cutter cylinders 1 and 2 via the guide plate 5. Cutter barrel 1 and 2
Since the cutters 8, 8 and 9, 10 mesh with each other on the center line, the signature is cut by the cutters 8, 8, and cuts are made on both sides of the signature as shown in FIG. is loaded and transferred to the next bookbinding process by transfer belts 6 ₁ and 6 ₂ .

Figures 7a and b show the saddle stitching process in the bookbinding process.
It is as follows. In the figure, the signature 11 transferred from the transfer device section E is placed in its storage box 1.
2 from inside by the upper bite cylinder 13, and the two lower bite cylinders 14, 14
The vehicle is then transferred to a chain 15, saddled on top of the chain 15, and transported. In this case, even if the folded folds to be transferred are the sutra folds shown in FIG. In this case, it goes without saying that the separated folds are not separated by the cuts in the side edges.

FIGS. 8a and 8b show the side-stitching process, in which the signatures 11 stored in the storage box 16 are pulled out by the gripping cylinder 17 and placed on the lower guide plate 18. Pole 19 dropped and transported
transported by. In this case, even when folded into three as shown in FIG.

Since the present invention has the above-mentioned configuration, even when the signature is folded outward, such as a sutra fold, a modified Z-fold, or a trifold, cuts are made on both sides of the fold, so it can be used as a type of simple binding. The folded pieces do not separate and fall apart during the subsequent operation using the feeder in the bookbinding process, or when handling saddle stitching, making it more efficient to proceed with the work. Moreover, such a function can be achieved simply by attaching a concave and convex cutter that faces the conventional cutter of the opposing cutter barrel.

Furthermore, even if the transfer belt 6 ₁ in the rotary cutter section D is omitted, or even if all the transfer belts 6 ₁ and 6 ₂ are omitted, the signatures will not vary, so the structure of the machine can be simplified. be able to.
