Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a saddle stitch binding method.

[Conventional technology]

A signature conveying means is composed of a thin endless belt such as an endless roller chain, and a large number of signature feeders are installed along this signature conveying means, and signatures are opened one after another on the running endless belt. Collating machines that perform collation by placing objects on top of each other are widely used. There is also a saddle-stitch binding device in which a spine stitcher (hereinafter referred to as a stitcher) is installed at the downstream end of the signature conveying means of this collating machine to perform saddle stitching, and then a cutting machine performs cutting. Widely used.

In these collating machines, bookbinding apparatuses, etc., a predetermined number of signature feeders are installed in one collating machine or bookbinding apparatus.

[Problem that the invention seeks to solve]

However, the number of signatures that make up the book that should be manufactured.

It varies depending on the number of pages of the book, the number of pages of the signature, etc. Therefore, when binding is performed using the bookbinding apparatus, the number of required signatures and the number of signature feeders may not match.

If the number of signatures is greater than the installed signature feeder, the predetermined number of signatures are collated and temporarily bound, and the collection of signatures is conveyed to the signature feeder of the bookbinding device again.

This requires a time-consuming and complicated process of setting and completing bookbinding, and is likely to result in quality defects such as misalignment.To avoid this, it is best to install a large number of signature feeders in advance; If you install a signature feeder, the number of signatures taken will often be less than the signature feeder.

In that case, the problem arises that the expensive signature feeder becomes idle.

The present invention has been made in view of such conventional problems.
Effectively use multiple folding machines or bookbinding devices.

To provide a saddle stitch binding method that enables bookbinding with a small number of folds or with a large number of folds.

[Means for solving problems]

In order to solve the above-mentioned problems, the present invention includes a signature conveying means made of a thin endless strip, and a signature conveying means provided along the signature conveying means, and a signature conveying means that opens the signature and transfers the signature to the belt-like body of the signature conveying means. At least two collating machines each having a plurality of signature feeders are provided, and the signatures being conveyed by the signature conveying means of one of the collating machines are taken out from the signature conveying means.

It is configured to be transferred to the signature conveying means of the other collating machine.

[Effect]

As described above, the present invention supplies signatures from one collating machine to the other collating machine, so there is no need to increase the number of signature feeders provided in one collating machine.

To enable bookbinding with many signatures. In addition, when binding books with a small number of signatures, each collating machine can be used for different binding operations, so that the signature feeder does not become idle.
Always used effectively.

Although the above embodiments all use a bookbinding apparatus equipped with a stitcher-1 cutting machine, etc., the present invention is not limited to this case, and can also be applied only to a 2-fold collating machine.

〔Effect of the invention〕

As is clear from the above description, one aspect of the present invention is to provide at least two collating machines each having a plurality of signature feeders along the signature conveying means, and to Since the structure is such that the signatures are taken out from the signature conveying means and transferred to the signature conveying means of the other collating machine, the number of signature feeders provided in one collating machine is increased. This makes it possible to perform bookbinding with many signatures, and also in the case of binding with a small number of signatures.

Each collating machine can be used for different book bindings.

As a result, the expensive signature feeder can be used effectively without being left idle, and even when binding a book with a large number of signatures, it is possible to perform temporary binding work and folding of signatures after temporary binding as in the past. This eliminates the need for the work of transporting the sheets and feeding them to the signature feeder of another collating machine, resulting in the effect that one work time can be shortened.
