Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention conveys signatures used for processing in bookbinding, etc., with the fold side facing down in a vertical posture in a row-stacked state and folded at the front end side in the conveying direction. The present invention relates to a signature supply device for sequentially extracting one copy from a copy and supplying the copy to the processing device side.

[0002]

2. Description of the Related Art A conventional saddle-stitch bookbinding machine is equipped with a number of signature feeders corresponding to the number of signatures required for binding a predetermined number of saddle-stitch books. Are arranged in order along a signature conveying path composed of a gathering chain.

Each of the above-mentioned signature feeding devices includes a vertical signature front end support plate for stacking and accommodating a signature group with the fold side facing down and being arranged in a row at an angle close to the horizontal, and a bottom support. A plate group and a stacking unit for the signatures, in which both side guides are arranged at both sides of the signature, that is, at positions corresponding to the upside-down direction of the saddle stitch book, are provided. And a paper feeding unit for feeding paper by pulling out one by one from a hole provided in the lower part of the front end support plate in order from a front end side signature in the carrying direction.

The mounting section includes a signature front end support plate,
A large number of signatures (a group of signatures) can be held inside the area surrounded by the bottom support plate and the side guides on both sides, and the signatures mounted on the mounting section are closer to the front end side in the transport direction. The signatures are sequentially extracted and conveyed one by one by the paper feed unit (vacuum method, signature extraction section by the jaw method), and the conveyed signatures eventually have their folds on the upper side and their open ends. With the section facing down, it is hung on a gathering chain (endless chain equipped with push claws at equal intervals) that is being fed, and one copy is fed from the signature feeder to the gathering chain. Are stacked in the order of a predetermined page on the signature that has been placed first, and are collated for each predetermined number of copies.

The collated signatures are eventually conveyed to a binding portion such as a stitcher (wire binding portion) and bound along the fold at the center of the signature, and then the other three folds other than the folds. Is cut and completed as a saddle stitch book.

The signatures mounted on the mounting base of these signature feeders are arranged vertically in a row bundle with the fold side down.
It is conveyed toward a sheet feeding section on the front end side in the conveyance direction by a conveyance section such as a belt conveyor-like feed mechanism arranged on the lower side of the mounting table, and the signature on the front end side is supported by a vertical support plate. The signature is sucked by the paper feed unit (vacuum suction unit of the paper feed unit), and the signatures are sequentially pulled out one by one from the front-end signature.

[0007]

However, when the signatures that are generally used for bookbinding are stacked in a vertical position in a horizontal state, the so-called signatures have a weak waist, and therefore, due to the weight of the signatures. In a so-called vertical stack type signature supply device that bends easily and bends easily in a vertical position, the signatures are mounted in a vertical position in a horizontal state on a mounting part It is difficult to maintain the vertical position (upright position) and replenish (additional replenishment) without doing so, and it requires skill. Also, when replenishing, it is continuous to the trailing edge of the remaining signature in the mounting part. There is a problem that the delivery mechanism for performing the delivery and delivery of the replenishing signature becomes large and complicated.

[0008] As a measure for eliminating the collapse of the signatures in the mounting portion, the signatures are laid horizontally and stacked in the vertical direction so that the signatures are stacked and mounted on the mounting portion. There is a signature supply device, but in this case, since the signatures are placed and supplied in a horizontal state, a stack of folded signatures (a group of signatures)
Although the above-mentioned problem that the paper collapses during transportation is solved, the total load of the signature group is at the bottom because the copies are extracted one by one from the bottom of the accumulated signatures and supplied. Compared to the vertical stacking type, there is a problem that misfeed (supply failure) is more likely to occur due to the accumulated load, and the number of stacking sections on the stacking section is larger than that of the vertical stacking type signature feeder. However, there is a problem in terms of efficiency in that only a small number of signatures can be mounted and accommodated in the mounting section.

The present invention avoids misfeeds due to bending of a signature due to the weakness of the signature of the signature in a stacking type signature supply device, and especially during the transportation during the supply of the signature. The purpose is to prevent the collapse of the signature group so that the signatures can be smoothly fed into the mounting section.

[0010]
