れないようになっている。Near the frame of the drive shaft 17, the cam gear
An intermediate gear 19 meshing with the gear 13 and having the same number of teeth as the gear 13 is fixedly provided, and a cam meshing with the sub input gear 8b and having a smaller number of teeth than the gear 8b is provided at an intermediate portion of the drive shaft. A drive gear 20 is rotatably supported via a support member 21 and a bearing 22. Further, an electromagnetic clutch 23 is provided around the drive shaft 17 near the support plate 15, and when energized by operating a button of an operation box (not shown), the rotation of the cam drive gear 20 is transmitted to the drive shaft 17 and conversely When is stopped, the rotation is not transmitted.
また、前記カムギア13の内面には円形のボス部25が一
体に形成され、このボス部25の外周にU字状の切欠き26
が案内面27とともに形成される。なお、耐久性を考慮し
て、図示例のように、切欠き26部分を耐久性のある別部
材で形成してボルト28でカムギア13に結合すると好適で
ある。A circular boss 25 is integrally formed on the inner surface of the cam gear 13, and a U-shaped notch 26 is formed on the outer periphery of the boss 25.
Are formed together with the guide surface 27. In consideration of durability, it is preferable that the notch 26 is formed of a separate durable member and connected to the cam gear 13 with a bolt 28 as shown in the example of the drawing.
一方、前記切欠き26に嵌合して前述した板カム12を所

フレーム1の外面に中間部を枢支されたレバー30の上端
に付設される。そして、このレバー30の下端に、基端部
において前記フレーム1に枢支されたエアシリンダ31の
ピストンロッド31a先端がピン結合される。On the other hand, a stopper roller 29 which fits into the notch 26 to fix and position the plate cam 12 at a predetermined position is attached to the upper end of a lever 30 whose intermediate portion is pivotally supported on the outer surface of the driving frame 1. . The distal end of the piston rod 31a of the air cylinder 31 pivotally supported by the frame 1 at the base end is pin-connected to the lower end of the lever 30.
前記エアシリンダ31は前述した電磁クラッチ23と同期
して作動され、電磁クラッチ23の通電時には収縮作動し
てストッパコロ29をボス部25から離間させ、逆に非通電
時には伸長作動してストッパコロ29を常時ボス部25の外
周へ当接させるようになっている。The air cylinder 31 is operated in synchronization with the electromagnetic clutch 23 described above. When the electromagnetic clutch 23 is energized, the air cylinder 31 contracts and separates the stopper roller 29 from the boss portion 25. The boss 25 is brought into contact with the outer periphery.
なお、第2図中35は折胴ギアである。 In FIG. 2, reference numeral 35 denotes a folding cylinder gear.
このように構成されるため、今操作ボックス内のボタ
ンをONにして電磁クラッチ23を通電すると、これと同期
してエアシリンダ31が収縮作動してストッパコロ29が切
欠き26内から離脱する。With this configuration, when the button in the operation box is turned on and the electromagnetic clutch 23 is energized, the air cylinder 31 contracts and the stopper roller 29 separates from the notch 26 in synchronization with this.
これにより、メイン入力ギア8aよりサブ入力ギア8bを
介して駆動されていたカム駆動ギア20の回転力が、電磁
クラッチ23の接続により駆動軸17及び中間ギア19を経て
カムギア13に伝達される。Thus, the rotational force of the cam drive gear 20 driven from the main input gear 8a via the sub input gear 8b is transmitted to the cam gear 13 via the drive shaft 17 and the intermediate gear 19 by the connection of the electromagnetic clutch 23.
この結果、前記カムギア13と一体の板カム12が、断裁
胴3の1回転に対し1.5回転の割合で増速回転され、前
記断裁胴3が1/3回転するごとに動作,不動作を繰返し
て2枚重ねの折り動作が行われる。As a result, the plate cam 12 integrated with the cam gear 13 is rotated at a rate of 1.5 rotations per rotation of the cutting cylinder 3, and the operation and non-operation are repeated every time the cutting cylinder 3 rotates 1/3. Thus, the folding operation of two sheets is performed.
一方、2枚重ねしない折り動作に切り換える時は、機
械の緩動状態で前述したボタンをOFFにして電磁クラッ
チ23への通電を止めれば良い。On the other hand, when switching to the folding operation in which two sheets are not stacked, the above-described button may be turned off and the energization to the electromagnetic clutch 23 may be stopped in a state where the machine is in a slow motion state.
これにより、電磁クラッチ23の切断で板カム12は駆動
源を失い、一時的に止まるが、やがてカムフォロア7の
コロ6と板カム12のリフト面とが係合することから、板
カム12が断裁胴3につれ回りされる。As a result, the plate cam 12 loses its drive source when the electromagnetic clutch 23 is disconnected, and stops temporarily. However, since the roller 6 of the cam follower 7 and the lift surface of the plate cam 12 eventually engage, the plate cam 12 is cut. It is hung around the torso 3.
この際、ストッパコロ29が前記ボタンのOFF時に同期
して、エアシリンダ31の伸長作動によりボス部25の外周
に当って転動さているため、板カム12が所定位置にくる
と、ストッパコロ29が自動的に切欠き26内に嵌合する。At this time, the stopper roller 29 is automatically rolled when the plate cam 12 comes to a predetermined position because the stopper roller 29 is rolled in contact with the outer periphery of the boss 25 by the extension operation of the air cylinder 31 when the button is turned off. It fits inside the notch 26.
この結果、板カム12が所定位置に固定位置決めされ、
前記裁断胴3が1/3回転するごとに動作して2枚重ねし
ない折り動作が行われる。As a result, the plate cam 12 is fixedly positioned at a predetermined position,
Each time the cutting cylinder 3 rotates 1 /, a folding operation is performed in which two sheets are not overlapped.

良い。In the above embodiment, the description is limited to the fixed positioning of the needle cam at the time of switching the folding specification, but in the present invention, in addition to the switching of the folding specification, at the time of replacement of the needle, the needle protrudes at an easily replaceable position. The present invention is also applicable to a case where the needle cam is fixedly positioned at a predetermined position. At this time, if the fixed positions of the needle change and the folding specification change are different, the aforementioned stopper roller 29, the lever 30 for moving the stopper roller 29, and the air cylinder 31 are connected to the boss 2
Another set of needle replacement may be provided at predetermined positions around the needle.
なお、本発明は前記実施例に限定されず、本発明の要
旨を逸脱しない範囲でストッパ機構等種々の変更が可能
てあることは言う迄もない。It should be noted that the present invention is not limited to the above-described embodiment, and it is needless to say that various modifications such as a stopper mechanism can be made without departing from the gist of the present invention.
