止する２枚取り防止装置に関する。[Detailed description of the invention] Industrial application field This invention is a bookbinding machine in which signatures are placed in the collating section.
Regarding the signature feeder that feeds copies one after another,
In particular, the present invention relates to a double-sheet prevention device that prevents two or more signatures from being fed at one time.

生じるという欠点があつた。BACKGROUND TECHNOLOGY A signature feeder of a bookbinding machine includes a means for raising and advancing signatures, such as an infeed belt, and a face plate that stops the advance of signatures.
the bottom edge of the signature secured by the face plate,
It has a suction bar that can be pulled out from under the face plate to be held in the claw of the upper cylinder of the collating part. In such a signature feeder, if the thickness of the signature is thin or the spine is poorly flattened, a so-called double feed occurs in which two or more signatures are carried by the upper cylinder at a time, resulting in machine stoppage or product defects. There was a drawback that it occurred.
考案の目的
本考案はかかる従来技術の欠点を解消せんとす

る。Purpose of the invention The present invention aims to solve the drawbacks of the prior art, and aims to provide a double-sheet-taking prevention device with a simple structure that can prevent double feeders.
考案の構成
本考案者は上記目的を達成すべく種々検討の結

し、この高さが低い程発生が少ないがあまり低く

ドを防止することを特徴とする。Structure of the invention As a result of various studies to achieve the above object, the inventor of the present invention found that the height of the lower end of the face plate from the infeed belt affects the incidence of double feed, and that the lower the height, the less the occurrence of double feed, but the lower the height, the less the occurrence of double feed. It has been found that if the height is lowered, so-called no-feeds, where signatures are not fed, increase, and there is a limit to the mounting position of the face plate, and it is not possible to lower the height sufficiently. Therefore, in the present invention, instead of lowering the face plate position, a leaf spring is provided on the face plate that extends downward from its lower end.
It is characterized by preventing double feed without increasing no feed.

FIG. 1 is a cross-sectional view of a main part of a signature feeder equipped with a double-sheet prevention device according to the present invention, and FIG. 2 is a perspective view thereof. In the figure, 1 is an infeed belt, 2 is a stock table, 3 is a face plate, 4 is a sukkah, 5 is an upper cylinder of the collating section of the bookbinding machine, and 6 is a pawl, which are known. be. A long and thin leaf spring 8 is attached to the front surface of this face plate 3 (the surface that contacts the signature 7).
It is attached so as to extend further downward than the lower end of the face plate 3. Although the leaf spring 8 may be fixed in a fixed position, it is preferable that the leaf spring 8 be mounted so that its position can be adjusted so that the length extending below the face plate 3 can be adjusted depending on the type of signature.

となく、折り丁が供給される。 Next, the signature feeding operation will be explained. The signatures 7 arranged vertically on the stock table 2 are advanced toward the face plate 3 by the infeed belt 1 and are pressed against the face plate 3. Next, the sutcher 4 pulls out the lower end of the signature peeking out from the lower end of the face plate 3, and the upper cylinder 5 pulls out the entire signature with the claw 6 grasping this lower end, and transfers it to the next cylinder (not shown). send. At this time, when the picker 4 pulls the bottom end of the signature toward you, the bottom end of the following signature may also move toward you at the same time and be grabbed by the claw 6 of the upper cylinder 5, but the leaf spring 8 The lower end of the signature is made difficult to move, and the occurrence of double feed in which two copies of the signature are grabbed by the claws 6 at the same time is greatly reduced. Moreover, the leaf spring 8 moves the bottom edge of the signature
Since it can be deformed when being pulled out, there is no problem in pulling out the most advanced signature, and so-called no-feed, in which the signature is not fed to the pawl 6 of the upper cylinder 5, hardly occurs. Thus, double feed,
Signatures are fed without much occurrence of misfeed such as no feed.

できる。 FIG. 3 is a graph showing the misfeed occurrence rate with respect to the height of the lower end of the leaf spring 8 when the leaf spring 8 is used. For comparison, Fig. 4 shows the misfeed occurrence rate when no leaf spring is used. As is clear from this figure, by using the leaf spring 8, both double feed and no feed can be reduced.
