イドの改良構造に関する。[Detailed Description of the Invention] Technical Field of the Invention The present invention relates to a paper folding device for folding creased continuous paper sent out by an output conveyance system, such as a stacker for a line printer, and in particular for folding paper that is sent out. The present invention relates to an improved structure of a paper guide, which is one of the structural means of the paper guide.
技術の背景上記のようなスタッカは一般に、ラインプリンタからの
用紙を紙送りローラによって下方へ放出し、用紙折りた
たみ部へ折りたたんで堆積するようになっている。BACKGROUND OF THE INVENTION A stacker such as the one described above generally ejects paper from a line printer downward by a paper feed roller, folds it into a paper folding section, and stacks the paper.
かかるスタッカにおける重要な問題は如伺にして用紙の
折目を放出順に折りたたむかにある。An important problem with such stackers is how to fold the folds of the sheets in the order in which they are released.
すなわち、用紙を単に自由放出しただけでは、折目の復
元性、空気抵抗、用紙の腰の強さ程度によっては、折目
が放出順に整然と折りたたまれず、先行の折目よりも後
続の折目の方が先に折りたたまれたりして円滑な折りた
たみが行なわれなくなる。In other words, if the paper is simply released freely, the folds may not be folded in an orderly manner in the order of release, depending on the restorability of the fold, air resistance, and the stiffness of the paper, resulting in the folds being folded more easily in the following fold than in the preceding fold. The other side may fold first, and folding may not be done smoothly.
尚、放出順に用紙の折りぐせの通り折りたたみたいとい
う要望は、このような折りたたみ状態が最も収容容積が
小さく且つその後の取扱いにも便利だからである。The reason for the desire to fold the sheets according to the folding pattern in the order of release is that such a folded state has the smallest storage volume and is convenient for subsequent handling.
従来技術と問題点このため従来より種々の用紙ガイド機構が提案されてい
る。Prior Art and Problems For this reason, various paper guide mechanisms have been proposed in the past.
例えば特願昭４４−３０６９７、および米国特許第２９
０６５２７号により、鎖（チェーン）を使用した用紙ガ
イド機構が提案されている。For example, Japanese Patent Application No. 44-30697 and U.S. Patent No. 29
No. 06527 proposes a paper guide mechanism using a chain.
この機構は、用紙放出路の両側に複数本の鎖を垂れ下げ
ておき、用紙が紙送りローラから送出されると用紙折目
が鎖に当接しながら順に下降して折りたたみが順序正し
く円滑に行なわれるようにしたものである。This mechanism has multiple chains hanging down on both sides of the paper ejection path, and when the paper is sent out from the paper feed roller, the paper folds descend one by one while coming into contact with the chains, ensuring that folding is done in an orderly and smooth manner. It was designed so that
しかるに上記の公知機構は次のような欠点がある。However, the above-mentioned known mechanism has the following drawbacks.
その１つは高速折りたたみの場合の問題である。One of them is the problem with high-speed folding.
すなわち、公知機構は長さおよび重量がほぼ同じで固有
振動数のほぼ同一な鎖を使用している。That is, known mechanisms use chains of approximately the same length and weight and with approximately the same natural frequency.
低速折りたたみの場合は用紙が鎖に強く当ることはない
ので鎖はほとんど振動せず、また多少振動しても用紙を
送り込み折りたたむ速度が遅いので鎖に突き当った用紙
の折目がまだ移動しない内に振られた鎖が戻って来るの
で、その機能は維持される。In the case of low-speed folding, the paper does not hit the chain strongly, so the chain hardly vibrates, and even if it does vibrate a little, the speed at which the paper is fed and folded is slow, so the fold of the paper that hits the chain does not move yet. The chain that was shaken will come back, so its function will be maintained.
しかし高速折りたたみの場合は用紙の送り込みが早くな
り、折目よりも高速で移動するので用紙が鎖に強く当っ
て鎖が振動することになる上、この場合、次の用紙折目
が放出された時にたまたま鎖が外方へ振動していてその
ガイド機能を果たさない事態が往々にして起り得る。However, in the case of high-speed folding, the paper is fed quickly and moves faster than the fold, so the paper hits the chain strongly and causes the chain to vibrate, and in this case, the next paper fold is ejected. Occasionally it may happen that the chain vibrates outwards and no longer performs its guiding function.
更には鎖が内方へ戻る際に用紙折目に衝突して悪影響を
与えることもある。Furthermore, when the chain returns inward, it may collide with the paper folds, causing adverse effects.
また公知機構のもう１つの欠点は鎖の帯電の問題である
。Another drawback of the known mechanism is the problem of chain charging.
即ち、鎖は一般に金属などの導電体から作られているが
、鎖の取付部材が電気的に絶縁されているために、帯電
した用紙が鎖に当接しながら滑り落ちる作用によって鎖
に静電気が蓄積し、静電吸着力によって用紙が鎖に吸着
されて折りたたみが乱れる場合があることである。In other words, chains are generally made of a conductive material such as metal, but because the attachment members of the chain are electrically insulated, static electricity accumulates on the chain due to the action of the charged paper sliding down while coming into contact with the chain. The problem is that the paper may be attracted to the chain due to electrostatic attraction force, causing the paper to be folded irregularly.

にある。Purpose of the invention Accordingly, the present invention aims to eliminate the above-mentioned drawbacks of the paper guide mechanism using chains as described above, that is, the guide mechanism can be obtained sufficiently even in the case of high-speed folding, and moreover, the paper adsorption due to the electrification of the chain It is an object of the present invention to provide an improved structure that can prevent the disorder of paper folding that occurs.
考案の構成本考案はかかる目的を達成するために、上記のような複
数の鎖を垂下させた用紙ガイド機構を具備した用紙折り
たたみ装置において、該用紙ガイドを構成する複数の鎖
を少なくとも２以上の異なる固有振動数の鎖で構成する
とともに該用紙ガイドをアースした事を特徴とするもの
である。Structure of the Invention In order to achieve such an object, the present invention provides a paper folding device equipped with a paper guide mechanism having a plurality of chains suspended as described above, in which the plurality of chains constituting the paper guide are arranged in at least two or more chains. It is characterized in that it is composed of chains with different natural frequencies and that the paper guide is grounded.
鎖の固有振動数を異ならしめるためには、個々の鎖の長
さを異ならしめれば可能である。In order to make the natural frequencies of the chains different, it is possible to make the lengths of the individual chains different.
なお、使用する全部の鎖を１本ごとに異ならしめる必要
はなく、数本づつ複数グループごとに異ならしめても良
い。Note that it is not necessary to make all the chains used different for each chain, but it is also possible to make them different for each group of several chains.
考案の実施例以下、本考案につき添附図面を参照し実施例にもとづい
て詳細に説明する。Embodiments of the invention Hereinafter, the present invention will be described in detail based on embodiments with reference to the accompanying drawings.
第１図は本考案による用紙折りたたみ装置の一実施例の
略本縦断面図である。FIG. 1 is a schematic vertical sectional view of an embodiment of a paper folding device according to the present invention.
まず、この装置全体の構成および作用を概略的に説明す
ると、例えばラインプリンタ（図示せず）から排出され
た用紙Ｐは紙送りローラ１および２によって振動させら
れながら放出口３から下方へ放出される。First, to roughly explain the structure and operation of this device as a whole, for example, paper P discharged from a line printer (not shown) is vibrated by paper feed rollers 1 and 2 and discharged downward from a discharge port 3. Ru.
この放出路の両側にはそれぞれ複数本の鎖５を垂れ下げ
た構造の用紙ガイド４が設けである。Paper guides 4 each having a structure in which a plurality of chains 5 are suspended are provided on both sides of this discharge path.
用紙Ｐは折目がこれら用紙ガイド４の鎖５に当接しなが
ら順に下降し、用紙受台６上に折りたたまれて堆積され
る。The sheets P descend one after another while their folds abut against the chains 5 of the sheet guides 4, and are folded and stacked on the sheet holder 6.
用紙受台６は、用紙受台６上に堆積された用紙Ｐの最上
面が放出口３より常に一定の距離となるように下降する
ように構成される。The paper holder 6 is configured to descend so that the top surface of the paper P stacked on the paper holder 6 is always a constant distance from the discharge port 3.
本考案は上記用紙ガイド４の特に鎖５に特徴がある。The present invention is particularly characterized by the chain 5 of the paper guide 4.
用紙ガイド４は第１図および第２図に示すように、機枠
側板７にブラケット８を取り付け、これに複数本（図示
例では９本）の鎖５を垂れ下げた構造である。As shown in FIGS. 1 and 2, the paper guide 4 has a structure in which a bracket 8 is attached to a side plate 7 of the machine frame, and a plurality of chains 5 (nine in the illustrated example) are suspended from the bracket 8.
第２図の例では鎖５は長さの異なる鎖５ａ、５ｂ、５ｃ
を含み、それぞれ３本づつ３グループにまとめて配列し
である。In the example shown in Figure 2, the chains 5 have different lengths 5a, 5b, 5c.
They are arranged in 3 groups of 3 each.
個々の鎖５ａ、５ｂ、５ｃは長さが異なるためその固有
周期が異なる。The individual chains 5a, 5b, 5c have different lengths and therefore different natural periods.
従って用紙Ｐの折目が鎖５に当って鎖が外方振動させら
れたときに原位置へ復帰するタイミングが異なるので、
従来のように全ての鎖が一斉に外方へ振動してしまうと
いう事態は実質的に解消される。Therefore, when the fold of paper P hits the chain 5 and the chain is vibrated outward, the timing at which the chain returns to its original position is different.
The conventional situation where all the chains vibrate outward at the same time is substantially eliminated.
すなわち、次の用紙折目が放出された際に鎖５ａ 、ｓ
ｂ 、５ｃのいずれかがガイドとして機能する本来の位
置であり、従って用紙折目は順次いずれかの鎖に当接し
ながら常に適当な保持力で支えられつつ整然と下降する
ことになる。That is, when the next paper fold is released, the chains 5a, s
Either b or 5c is the original position to function as a guide, and therefore, the paper folds will descend in an orderly manner while coming into contact with one of the chains sequentially and always being supported by an appropriate holding force.
なお、第３図および第４図は鎖５ａ、５ｂ、５ｃの他の
配列の例を示すものである。Note that FIGS. 3 and 4 show examples of other sequences of chains 5a, 5b, and 5c.
第３図の場合は３種類の鎖５ａ、５ｂ、５ｃを交互に配
夕１ルたものであり、用紙が常に幅方向全体に亘ってガ
イドされる点で第２図の例よりも好ましい。In the case of FIG. 3, three types of chains 5a, 5b, and 5c are arranged alternately, which is preferable to the example of FIG. 2 in that the paper is always guided over the entire width direction.
また第４図の場合は個々に長さの異なる鎖を長さの順に
並べたものであり、第２図の場合とほぼ同様の機能を有
する。Further, in the case of FIG. 4, chains having different lengths are arranged in order of length, and has almost the same function as the case of FIG. 2.
また、上記の鎖５は導電性金属から作られており、用紙
ガイド４には第１図に示すようにアース９を接続しであ
る。The chain 5 is made of a conductive metal and is connected to the ground 9 to the paper guide 4 as shown in FIG.
これにより帯電した用紙Ｐの鎖５との当接及び滑りによ
って生ずる静電気が鎖５に蓄積されること、すなわち鎖
５の帯電を防止できるので、その結果として用紙Ｐが鎖
に吸着されるのを防止することができ、用紙折りたたみ
のために帯電による吸着がない場合を基準にして設定し
た条件を乱すことがなくなるので用紙Ｐの乱れのない円
滑な折りたたみが実現される。This prevents static electricity generated by the contact and sliding of the charged paper P with the chain 5 from being accumulated on the chain 5, that is, from charging the chain 5. As a result, the paper P is prevented from being attracted to the chain. Since the conditions set based on the case where there is no adhesion due to electrostatic charge for paper folding are not disturbed, smooth folding of the paper P without disturbance is realized.
尚上記の実施例では第２図に示すようにブラケット８は
側板７に枢軸１０で回転可能に取り付けである。In the above embodiment, the bracket 8 is rotatably attached to the side plate 7 about a pivot 10, as shown in FIG.
これは用紙Ｐの折りたたみ幅に応じて両側の用紙ガイド
４の鎖５の間隔を調節するためである。This is to adjust the interval between the chains 5 of the paper guides 4 on both sides according to the folded width of the paper P.
この場合、ブラケット８は枢軸１０に取り付けたばね１
１によって通常は回転しないように保持されている。In this case, the bracket 8 is attached to the spring 1 attached to the pivot 10.
1, it is normally held so as not to rotate.
考案の効果以上の説明から明らかなように、本考案によれは、ガイ

により特に高速折りたたみの場合にも用紙ガイド４がそ
の機能を維持することができ、また用紙ガイドのアース
により鎖の帯電を防止して鎖への用紙の吸着を防止した
ことによって円滑な用紙折りたたみを行なえる。Effects of the Invention As is clear from the above explanation, the invention allows the paper guide 4 to maintain its function even during high-speed folding because the chains constituting the guide are composed of chains with different natural frequencies. Furthermore, by grounding the paper guide, the chain is prevented from being charged and the paper is prevented from adhering to the chain, so that the paper can be folded smoothly.
また構造も非常に簡単であり、極めて実用性の高いもの
と云える。Furthermore, the structure is very simple and can be said to be extremely practical.
