【考案の詳細な説明】 〔産業上の利用分野〕 本考案は、たとえば巻折式折機に使用する紙押え装置に
関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a paper pressing device used in, for example, a folding folder.
巻折式折機の正面図を第３図に、側面図を第４図に示
す。A front view and a side view of the roll-folding machine are shown in FIGS. 3 and 4, respectively.

折帳は送行テープ５によりデリバリフアン６に送られ、
デリバリフアン６により整列させられる。The sheet of paper 1 is cut by the cutter cylinder 2 to have a constant circumference, and the first folding is performed between the cutter cylinder 2 and the first gripping cylinder 3 to form an intermediate signature. Further, the transport paper 1, which is an intermediate signature, is folded for the second time between the first gripping cylinder 3 and the second gripping cylinder 4, and becomes the final signature. Then, the final signature is sent to the delivery fan 6 by the delivery tape 5,
Aligned by delivery fan 6.
上記工程において、最終折帳の折り精度を向上させるた

行に配置され、両端をフレーム９に回転自在に支持され
ている。In the above process, it is necessary to remove the bulge of the intermediate signature in order to improve the folding accuracy of the final signature. Therefore, as shown in FIG. 5, the elastic force of the cantilever-supported leaf spring 7 is utilized to press the intermediate signature with the tip of the leaf spring 7. Reference numeral 8 denotes a support shaft, which is arranged parallel to the rotation axis of the first gripper cylinder 3 and has both ends rotatably supported by the frame 9.
10はホルダで、ホルダ11と組み合わされて支持軸８に固

ヤである。Reference numeral 10 denotes a holder, which is combined with the holder 11 and fixed to the support shaft 8 to position the leaf spring 7 to be placed. In addition,
Reference numeral 12 is a spring-provided contact plate, which overlaps the plate spring 7 and constitutes a laminated plate spring. 13 is Washiya.
先端で中間折帳を押える板ばね７には繰返し応力が加わ
るから、長時間使用していると折れる。Repeated stress is applied to the leaf spring 7 that presses the intermediate signature at the tip, so that the leaf spring 7 breaks when used for a long time.
このとき折れた板ばね７が飛散し、中間折帳に巻きこま
れて中間折帳と一体になつて移動すると、他の装置を傷
つけてしまう。このため、板ばね７に寿命が来ていなく
ても、所定の時間ごとに新しいものと交換しなければな
らないという問題点があつた。At this time, the broken leaf springs 7 scatter and are wound around the intermediate signature, and when moved together with the intermediate signature, other devices are damaged. For this reason, there is a problem that the leaf spring 7 must be replaced with a new one every predetermined time even if the life of the leaf spring 7 is not reached.
本考案の目的は、上記した課題を解決するため、板ばね
７を寿命が来るまで使用できる構造にすることによつて
板ばね７の交換頻度を減らし、作業能率を向上させると
ともに、ランニングコストを低下させることにある。In order to solve the above problems, the object of the present invention is to reduce the frequency of replacement of the leaf springs 7 by making the leaf springs 7 usable until the end of their life, improving the work efficiency and running cost. To lower it.
上記した課題を解決するための手段を、本考案の一実施
例を示す第１図により説明する。Means for solving the above problems will be described with reference to FIG. 1 showing an embodiment of the present invention.

の両者にはそれぞれ切欠き部25が設けてあり、先端にく
り返し荷重がかかり疲労して折れるときには、それぞれ
切欠き部25で破断するようにしてある。A holder 18 is fixed to the support shaft 8 in combination with the holder 11. A leaf spring 14 is fixed to the holder 18 at one end together with the contact plate 21. A hole 15 is provided in the beam portion of the leaf spring 14, and a hole 22 is provided at a position corresponding to the hole 15 of the plate 21. Reference numeral 16 denotes a support, which is integrated with the holder 18 via a bracket 17 fixed to one end of the holder 18. 19 is a screw hole provided in the support 16. 20 is a bolt, the head is a hole
Larger than 15 and 22, the shank penetrates holes 15 and 22 and screw holes 19
It is screwed to. The bolt 20, the leaf spring 14 and the contact plate
It does not have to be in contact with 21. 23 is a spring. 24 is a spring 23
It is a bolt for adjusting the pressing force of. Further, as shown in FIG. 2 which is an A view of FIG. 1, a leaf spring 14 and a contact plate 21 are provided.
Both of them are provided with notches 25, and when the tip is repeatedly subjected to a repeated load and is broken due to fatigue, the notches 25 are broken.
以下、動作について説明する。The operation will be described below.
巻折式折機を稼動させるときには、支持軸８を所定の角
度回転させ、板ばね14の先端を第１咥え胴に向つて押し
付け、板ばね14を弾性変形させる。中間折帳は板ばね14
に押えられるから、ふくらみは発生せず、精度のよい最
終折帳を得ることができる。When the roll-folding machine is operated, the support shaft 8 is rotated by a predetermined angle and the tip of the leaf spring 14 is pressed toward the first jaw cylinder to elastically deform the leaf spring 14. Intermediate signature is leaf spring 14
Since it is pressed by the bulge, bulge does not occur and the final signature can be obtained with high accuracy.
長期間使用すると、板ばね14は疲労し、遂には最も弱い
位置である切欠き部25の位置で破断する。そして、破断
した板ばね14はボルト20により飛散することなく、ボル
ト20に保持される。また、当板21が折れた場合も同様に
してボルト20に保持される。When used for a long period of time, the leaf spring 14 becomes fatigued and finally breaks at the position of the notch 25, which is the weakest position. Then, the broken leaf spring 14 is held by the bolt 20 without being scattered by the bolt 20. Further, when the contact plate 21 is broken, it is similarly held by the bolt 20.
なお、本実施例においては、重ね板ばねを構成する板ば
ね14と当板21のたわみをばね23によつて規制しているか
ら、従来の構成のものにくらべ寿命を長くすることがで
きる。In addition, in the present embodiment, since the deflection of the leaf spring 14 and the contact plate 21 which constitute the leaf spring is controlled by the spring 23, the life can be extended as compared with the conventional configuration.
また、片持ちばりの場合、一般に固定端すなわち、ワツ
シヤ13の端面の位置で折れるから、切欠き部25は特に設
けなくてもよいことは言うまでもない。Further, in the case of a cantilever, it is needless to say that the notch 25 does not have to be particularly provided, since it is generally bent at the position of the fixed end, that is, the end face of the washer 13.
さらに、ボルト20の代りに銷などを用いてもよいし、穴
15の代りに係合部材を板ばね14に固定させてもよい。In addition, instead of the bolt 20, you may use a pig, etc.
Instead of 15, the engaging member may be fixed to the leaf spring 14.
以上詳述したように、本考案によれば、板ばね14が折れ
てもボルト20に保持されるから、板ばね14が折れるまで
使用することができる。従つて、板ばね14の交換頻度が
減り、作業能率を向上させることができるという効果が
ある。まだ、ライニングコストが低下するという効果も
ある。As described above in detail, according to the present invention, even if the leaf spring 14 is broken, it is held by the bolt 20, so that it can be used until the leaf spring 14 is broken. Therefore, there is an effect that the frequency of exchanging the leaf springs 14 is reduced and the work efficiency can be improved. There is still the effect of reducing the lining cost.
